Welcome Message
Local Host
Dr. Hiroshi Uechi
Faculty of Commerce
Osaka Gakuin University
Dear delegates,
It is my great pleasure to welcome you to the joint conference of Annual Conference on Engineering
and Applied Science (ACEAT), International Conference on Life Science and Biological Engineering
(LSBE), and Annual Conference on Management and Social Science (ACMASS) in Osaka, Japan,
which promotes exchanges of information, communications and collaborations among researchers
worldwide. The 21st century is the age of atomic and molecular science, and the age of exploration to
Mars and possibly to other planets using spacecraft technology. We gradually come to understand the
earth as the unique spacecraft in the universe, and we need collaborations not only from scientists but
also people with all expertise in order to resolve problems and sustain our societies and ecological
systems, energy resources, etc. The international conferences such as ACEAT, LSBE and ACMASS
would help mutual understandings and play more important and valuable roles in due course. Above
all, we would like to welcome all of you to the above conferences and also hope that every participant
will enjoy cultural explorations in Japan.
Yours sincerely,
Dr. Hiroshi Uechi

Nanostructured Metal Oxide Materials for Energy Storage
Dr. Kwun Nam Hui
Associate Professor
University of Macau
Abstract
With the rapid development of electronic technology, wearable and flexible devices such as roll-up
displays, biomedical sensors, and wearable devices, have drawn considerable attention. Developing high
energy density flexible supercapacitors (FSCs) hold the promise to provide a safe, fast charge/discharge
rate, and long-life flexible energy storage devices. To date, electrodes of high-performance FSCs are
mainly composed of carbonaceous materials such as carbon nanotube (CNT), graphene and
CNT/graphene hybrid due to their distinct properties of high conductivity and mechanical flexibility.
However, the CNT/graphene-based electric double-layer capacitor possesses low specific capacitance due
to its intrinsic double-layer charge storage mechanism, which relies on the electrostatic attraction of
electrolyte ions and charges at the electrode surface. Accordingly, hybridizing pseudocapacitive metal
oxide materials with carbon-based materials such as CNT and graphene has become an appealing strategy
in increasing the specific capacitance and energy density of film electrodes. In this talk, the speaker will
present his recent work in the development and application of nanostructured metal oxide electrode for
high-performance flexible supercapacitors. Several strategies, including the morphology control,
core/shell architecture, and defect engineering, will be discussed to improve the electron transports,
electrolyte ions diffusion kinetics, and electrical conductivity of metal oxide electrodes.

Topic:
Reviving the Engineers in Our Genes
Abstract
It can be said that the history of mankind is the history of engineering. Archaeology tells us that Homo
habilis, the oldest known human species who had the ability to create and use tools more than 2 million
years ago also developed a brain double the size of its predecessor who had started walking on two legs
another million years before. Evolutionary Psychology also tells us that engineering started when
evolution shaped what we call the engineering mind in our ancestors. Urge theory of Toda (1981)
postulated that human emotions evolved to survive in natural environments in which our ancestors lived
during most of the human history. An urge is a set of emotion and action that, upon encountering a certain
type of situations, ‘urges’ us to do certain actions that optimize our chance of survival in those situations.
Let us examine two types of urges that are relevant for the history of engineering.
Learning urges: emotions like curiosity and challenge which were essential for learning the skills and
knowledge necessary to make and use tools.
Social urges: helping urge giving the motivation to help others in need or contribution urge to do
something useful for the community.
These urges were the driving force behind the ancient engineering, inventing and improving many useful
tools. These mental functions were adaptations to the natural environments in which our nomadic
ancestors survived by hunting and gathering for millions of years. However, the engineering driven by
20
these urges has, by making new kinds of tools, changed the very environments in which they had evolved
to function. Some groups of homo sapiens started to engineer the environments when they invented
agriculture about several hundred thousand years ago which then spread to most other groups. Farming
forced them to shift from the nomadic lives with simple tools to settled lives with larger and more
complicated tools, creating houses, storages, villages, and weapons to protect them. Then only about a
few hundred years ago, less than 0.1% of the human history, engineers invented machines that used fossil
energies which led to the industrial revolution, changing our environments drastically and fundamentally.
When our environments change so rapidly, there is no time for our genes to properly adapt to them, and
these urges no longer function properly in our modern environments. For example, learning urges like
curiosity and challenge seem to work well in young children when they play with natural objects or
simple toys, but as they grow older and the tools and toys they use become more and more complicated, it
becomes more difficult to feel curious about their mechanisms or feel challenged to make the toys/tools
themselves. Social urges like help urge or contribute urge are difficult to function in modern
environments because the natural and human resources that support our daily lives have become invisible.
Thus, more and more people buy and consume things that are produced by people they never meet using
resources they never see, and those who produce things in factories never meet the users, and never know
where the materials and energies they use are from. Humans have created environments in which most
people are caught in what Ivan Illich (1973) called "radical monopoly" in which they have to rely on huge
systems that supply them foods, energy, health, and everything they need to survive in exchange of money,
which they must earn by keep working, rather than working together to help each other live. This
ignorance of the production processes has caused many global issues, such as environmental destruction,
inequality, and exploitation of poorer communities.
The history of engineering is so ironical: the engineering mind that was supposed to function in natural
environments actually have created environments that it cannot function well, thus making it more
difficult to do engineering with proper motivations and producing solutions that can address more
sustainable benefits rather than short-term gains. What can engineering do to fix this situation?
In our keynote presentation, we propose some directions for revising the engineer design process to try to
answer this question. This new process introduces stages including stakeholders identification and
evaluation, experience and roleplaying workshops as well as participatory design practice. With these new
stages, we hope the learning urges and social urges in our engineering minds could be revitalized, while
the objectives and engineering solutions could also be realigned to help yielding sustainable benefits. As a
result, it may help us to escape from this vicious cycle.

Narcissism and Antisocial Personality: Global Challenges for Business and
Beyond
Dr. Meg Milligan
Associate Professor
Troy University
Abstract
Narcissism refers to a set of characteristics that describe some individuals’ basic personality style, as well
as to a mental disorder called Narcissistic Personality Disorder (NPD). Narcissistic traits include
arrogance, self-centeredness, need for admiration, a sense of entitlement, interpersonal exploitation, and
lack of empathy. The term derives from the myth of Narcissus, who fell in love with his reflection in a
pool of water, and this led to his demise. Research indicates a trend toward increasing narcissism
worldwide.
The Diagnostic and Statistical Manual of Mental Disorders (DSM), the text used by mental health
providers as a basis for diagnosis, added NPD to its third edition in 1980. All subsequent editions list
NPD, including the most recent, the fifth edition, published in 2013. NPD is included in the World Health
Organization’s (WHO) international companion, the International Classification of Diseases, Tenth
Revision (1992), as well.
Narcissistic traits are prominent in other DSM personality disorders, most notably Borderline Personality
Disorder (BPD), depicted in the movie Fatal Attraction, and Antisocial Personality Disorder (ASPD), with
its salient psychopathic personality component, exemplified by Joseph Stalin of the Soviet Union, and
serial killers such as Ted Bundy in the U.S. The prototypical psychopath is a superficially charming,
impulsive, manipulative, remorseless, pathologically lying, male social predator with an inflated sense of
self. A synthesis called the Dark Triad, which describes a particularly dangerous type of personality,
focusses on psychopathy, narcissism, and Machiavellianism (deceitful, amoral, master manipulators).
Narcissism has a compelling fascination for a wide audience. Although the negative and destructive
aspects are obvious, such as its association with criminality, aggression and vengeance, there appear to be
22
some positive applications in certain contexts, such as productive narcissism, successful leadership if
these individuals are managed effectively, and positive organizational narcissism.
A resurgence of interest in narcissism accompanied President Trump’s election, the “narcissistic”
millennial generation’s ascendency, concerns about narcissism in politics and big business, and a general
trend toward globalization. Furthermore, data indicate increasing individualism, focusing on oneself
rather than group wellbeing, worldwide, with a corresponding decrease in collectivism, concern for the
common good.
Examples of business leaders with narcissistic tendencies include Andy Fastow, ex-CFO of Enron, who
contributed greatly to his company’s demise and spent six years in prison; Bernie Madoff who
orchestrated the most costly financial fraud in U.S. history; and Facebook founder, Mark Zuckerberg,
who faces backlash from data security breaches that affect millions of people worldwide. In addition,
collective narcissism, a belief that one’s group is superior to other groups and that others can be quashed,
first applied to Adolf Hitler, as well as the type of abnormal narcissism seen in ASPD, seem widely
applicable in today’s world.
It is clear that people with narcissistic and antisocial personality traits can present huge problems to
today’s businesses and beyond, whether these traits are in the normal range or not. My address (1)
describes narcissism and antisocial personality, (2) discusses the positives and negatives applied to
business and social issues, and (3) depicts the current and future challenges to international business and
global society presented by narcissistic and antisocial behavior, as well as some possible solutions.

The Controversial Portrait of the “Hero”: Saigo Takamori and His Sei-Kan Ron
in the Early 1870s
Dr. Mizuno Norihito
Professor
Akita International University
Abstract
It would not be an overstatement that Saigo Takamori is one of the most heroically or favorably described
historical figures in Japan today, for example, as Saigo has ever been picked up as the protagonist of
NHK’s year-long historical TV drama called Taiga drama twice, including this year. His dramatic life as
one of the primary contributors to the imperial restoration in the late 1860s and as the leader of the
anti-government armed uprising in the late 1870s and his personality has been attracting the Japanese.
However, in postwar Japan under the so-called pacifist constitution, it seems to be arduous to fit his
controversial proposal for Korea policy in 1873 into the popular image. The policy proposal called
Sei-Kan ron has become an issue among historians since the late 1970s. Inside and outside of academia,
there are conflicting two theories on his intent: some regard him as a jingoist advocating a military
solution to break through stagnated normalization talks with Korea, also expecting a war to materialize
his domestic and external objectives. Others contend, however, that Saigo sought for and was even
confident in settling the diplomatic trouble peacefully. This presentation does not find convincing grounds
to support the pacifist theory in which the postwar Japanese ethos would more affinity, and instead argues
that he never dropped the use of force as a policy option.
Keywords: Saigo Takamori, Japan, Japanese-Korean Relations, Meiji Era

1. Background
Sludge as a by-product from wastewater treatment in the textile industry is increasing every year due to
the increasing need of traditional and modern clothing along with the increase of population in the world,
particularly in Indonesia. The polluted soils have negative impacts on agriculture production and human
health. The objective studies are to assess plant toxicity of the textile-sludge contaminated soils, and to
measure effect of adding citric acid as a natural chelating agent on Zn concentrations of the contaminated
soils, plant growth and Zn uptake by sunflower.
2. Results
The plant height of S0C0 was 67.2 cm significantly higher than the other treatments, which of S1C1 was
51.8 cm significantly higher than that of S1C0 and S1C2. Dry biomass distributions of root, stem, leaf
and flower were in the range of 8-15%, 36-49%, 22-25% and 19-29% of the total dry biomass,
respectively. Table 1 represent plant biomass (dry bases), Zn concentrations of soil and plant, and Zn
uptake of sunflower at 8 WAT. The highest total dry biomass was 5.1 mg/plant (S0C0) and not
significantly higher than that of S0C1, S0C1 and S1C1. Application of citric acid on S0 and S1 treatments
was suppressed plant height of 30% and 57%, and decreased dry biomass of 36% and 78% of the highest
total dry biomass, respectively. However, the treatment of S1C1 had the lowest plant height suppression
and biomass decrease of 23% and 33%, respectively. Concentrations of Zn on S0 treatments were tended
to decrease with increasing dose of citric acid, but Zn concentration of S1C1 was significantly higher than
that of S1C0. Similarly, Zn uptakes were not significantly decrease on S0 treatment, but significantly
higher on S1C1 than S1C0 and S1C2 treatments.

Abstract
Genetically engineered micro-organisms have been widely used for producing high added value
biomolecules such as pharmaceuticals, biofuels and natural products. To facilitate advancements in
biotechnology and synthetic biology, the CRISPR/Cas9 system was developed to become the most
effective and commonly used DNA engineering tool for gene activation, gene interference, gene
knock-out and knock-in. E. Coli and S. Cerevisiae are the two strains frequently used in research and
industries. Successful genomic editing of these stains with CRISPR/Cas9 provides great advantages when
studying a gene’s function as well as cell factory development. At Synbio Technologies, we utilized our
propriety Genotype-Phenotype-Synotype (“GPS”) platform build up an E. Coli gene editing platform that
successfully generates gene knock-in or knock-out in E. Coli genome. We have successfully engineered E.
Coli by introducing butanol synthase genes into its genome, resulting in a new strain expressing butanol.
Moreover, we also constructed a universal gene editing vector for S. Cerevisiae and Pichia. Using this
vector, the ADE1 gene of S. Cerevisiae was successfully knocked-out, which led to the inhibition of
adenine related synthesis pathway and accumulation of red pigment in cells, resulting in a “pink” S.
Cerevisiae strain. Using the same technique, another S. Cerevisiae strain was also engineered to stably
produce albumin by an insertion of a HindIII endonuclease site within the albumin denaturation gene
(YPS1). Through these experiments, we have displayed that the CRISPR/Cas9 system is remarkably
flexible and programmable for multiplexed gene editing and regulation in micro-organisms.

1. Background
Phosporotioate antisense oligonucleotides (ODNs) as a gene silencing of malarial Erythrocyte Binding
Agent (EBA) 175 and Deoxyhipusin Sintase (DHS) have shown to posses promising features an anti
malarial agents because of the rapid emergence of drug resistance all current drugs. To improve its
stability from nuclease degradation and increase cellular penetration, ODNs EBA 175 and ODNs DHS
were complexed with combination of three biomedical polymers namely chitosan (CS),
poly-lactic-co-glycolic acid (PLGA), and poloxamer. This study describes the formulation and process
modification to improve the nanoprecipitation technique, particularly to the physicochemicals and
morphology of ODNs polymeric nanoparticles. Furthermore, the principal objective was to explore the
influence of such modification on nanoparticle size.
2. Methods
Selected parameters on the nanoprecipitation method, such as the polymer ratio, rate and time of stirring,
were varied to obtain polymeric nanoparticles. The physicochemicals ODNs polymeric nanoparticles
were characterized by Dynamic Light Scattering measuring of particle size, polydispersity index and zeta
potentials. The morphology were characterized by Transmission Electron Miscroscopic (TEM).
3. Results
The results reveal that spherical nanoparticles with particle size less than 200 nm, the particle size
distribution in the range 0.3 – 0.5 and zeta potential approximately +27 mV were obtained in poloxamer –
PLGA ratio (10:1), 900 rpm and 2 h of stirring. The presented results demonstrate that nanoprecipitation
method in ODNs polymeric nanoparticle was affected by polymeric ratio, rate and time of stirring.

Abstract
Recent years, biological signals have attracted much attention as a tool of human interface.
Electromyogram (EMG) has been used in a variety of situations in particular. Generally, EMG in
muscular volume of arms or shoulders has been measured in many cases. In addition, expensive wet type
sensors have been often used. However, they are inconvenient and high-cost. On the other hand, in hand
motion recognition and personal authentication using wrist EMG, we have obtained good results.
However, accuracy is poor when hand motion recognition and personal authentication are carried out at
the same time. For the above reasons, we carry out hand motion recognition and personal authentication
at the same time, and try to obtain higher accuracy than the previous research. The conventional method
used EMG of movement Japanese Janken (Fig.1). We use a multi-input and multi-output model of a
Convolutional Neural Network (CNN). The average accuracy of hand motion recognition is 94.6%. The
average accuracy of personal authentication is 95.0%. In this paper, we use a Wide Residual Network
(WRN). The average accuracy of hand motion recognition is 97.8%. The average accuracy of personal
authentication is 98.4%. In future work, we aim to improve accuracy by adjusting WRN parameters. In
addition, we prepare a class not belonging to any class in multi-class classification.

Abstract
This article aims to evaluate the effects of number and position of mini dental implant (MDI) on stress
and strain distribution by performed three-dimensional Finite Element Analysis (FEA) in edentulous
mandibular and evaluate von Mises stress and maximum principal strain in different ten overdenture
conditions. Firstly, 3D part of edentulous mandibular was reconstructed from a computed tomography
(CT) analysis (Faculty of Dentistry Chiang Mai University) which were inserted by two, three, four and
five mini dental implants (MDIs) on different positions. Mini dental implant model and other components
were modelled analogous to real mini dental implant diameter 2.75 mm. After reconstruction procedure,
all components were processed to finite element analysis procedure (FEA). In FEA procedure all
components were assembled and assigned necessary mechanical properties. Load was applied 200 N on
posterior teeth (first molar) under bilateral condition. Stress and Strain were compared and analyzed by
multiple statistical procedure (Volume-average, Geometric mean) 1 mm in peri-implant area. Preliminary
results from FEA procedure von Mises stress and Maximum principle strain seem clearly interpret
relationship in number of mini dental implant and trends of stress and strain values. Therefore, the
volume average method was used to further explain this relationship. The result reveals that when number
of mini dental implant increased the stress and strain values tend to decrease 1 mm around peri-implant
area both cortical and cancellous bone. A gap between both stress and strain values decrease when mini
dental implant was inserted. From mini dental implant position perspective, the results showed both stress
and strain around in peri-implant area decrease when an implant position away from loading position. The
results of this study can conclude that number and position of mini dental implant significantly affects
stress and strain on peri-implant bone.

Abstract
The utilization of Accounting Information System (AIS) by the small, medium, and micro enterprises
(SMEs) at present is apparently at the minimum level if not to mention the integrated operation. This study
attempts to fathom and analyze, first, the impact of subsequently the system quality, the information
quality, the top management support upon the perceived usefulness. Second, the effect of the system quality,
the information quality, and the top management support on the end-user information satisfaction. Third,
how the perceived usefulness affects the end-user information satisfaction. Fourth, to analyze the effect of
the system quality, the information quality, and the top management support on end-user information
satisfaction via the perceived usefulness.
The study observed the designated SMEs managers in a chosen area of targeted location in East Java,
Indonesia. The structural equation modeling was employed to study the effect of those variables under
study, namely the system quality, information quality, top management support on the end-user information
satisfaction through the perceived usefulness.
The results revealed that the system quality, the information quality, as well as the top management support
proven to be affecting the designated SMEs perceived usefulness. Among those variables under study, it
was proved that the system quality, information quality, top management support influence on the end-user
information satisfaction. However, the perceived usefulness is an intervening variable that can mediate the

Abstract
Biological asset is a living animal and plant that have biological transformation. International Accounting
Standards Council (IASC) has published International Accounting Standard (IAS) 41 Agriculture which
regulates the biological assets, but its deemed inappropriate for accounting biological asset especially
animals owned by theme park, because recreational activity is not agricultural activity as there is no
management of the biological assets but simply control of the number of animals.
This research conducted at 3 (three) theme parks in Bali, Indonesia, with purpose to disclosure the
accounting treatment of biological asset owned by theme parks. The result shows that the first and second
theme parks use IAS 16 Property, Plant and Equipment as the basis of accounting treatment for biological
asset, while the third theme park uses IAS 38 Intangible Asset.
The first and second theme parks recognized their biological asset as Other Asset and measured value of
biological asset based on the cost of permit. The third theme park recognized their biological asset as
Property and Equipment and measured biological asset based on its estimation of cost of raising the
animal through estimated average life for its species.
Recommendation given is that theme parks specialized in zoological activity should report their
biological assets gained from exchanges with other theme park at acquisition cost. Animals born on the
theme parks should be recorded at the cost of raising the animals into adulthood. Accounting standard use
is the IAS 16.

Abstract
Previous studies show that population aging usually puts downwards pressure on house prices, however,
that is not the case of China. Based on the analysis of house prices rising, population aging, availability of
financial services and failure in optimizing the allocation of household assets in China, this paper
examines the role of financial availability in the relationship between population aging and housing price,
and offers a new explanation for the impact mechanism of China's population aging on housing prices.
First, a theoretical model is developed to study the interaction between population aging, financial
availability and housing prices in China. Then, using the prefectural panel data from 1999 to 2015 in
China, we carry out empirical test by adopting both static and dynamic models. The empirical results
show that in China, the effects of aging on house prices is highly depend on the availability of financial
services. When financial availability level is low, the aging has positive effects on housing price. With
increase access to financial services, the effects reserves. Our empirical results verify our theoretical
model in explaining why and how financial availability plays a role in the relationship between
population aging and housing prices. We argue that the insufficient financial availability leads to "a
shortage of financial asset ", which results in the contradiction between residents' large demand for assets
and insufficient supply in the financial market. As a result, China’s house prices continue to increase
because a large amount of funds pour into real estate market.

Abstract
Financial management is very important in a family to avoid financial problems of the family itself.
However, the capacity of low socioeconomic family understanding in managing family finances is
certainly not the same as an able family or a family with income above average exposure. This study aims
to explain thoroughly the model of low socioeconomic family financial management through the
perspective of street children mothers from Muntigunung, Tianyar Barat, Karangasem (informants),
relating to how to recognize and manage family finances, prioritizing home needs stairs, and income
allocation for savings.
This type of research is qualitative descriptive research with the process of collecting data through
participant observation, unstructured interviews, and documentation. Data analysis using interactive
model data analysis with three flow analysis, namely data condensation, data presentation (data display),
and conclusions or verification.
The result in general, informants do not understand how to properly manage finances. Their educational
and environmental limitations are classified as poor, encouraging them to prefer to borrow if they have
financial problems. If they get a salary, the meal will be used to pay the debt. But this debt process
continues every month and causes no desire to save (set aside income). Then, income is something that is
used to meet religious needs and family needs, debt is another way to meet needs (if income has run out),
while saving is not a solution to fulfill their needs.

1. Background
According to a 2015 assessment, the average flight in the region is currently delayed by 29 minutes and
this could reach 59 minutes by 2025 without action, due to air traffic control capacity and staffing issues.
Connectivity increases as the range of destinations increases, the frequency of service increases and/or
larger “hub” airport destinations are served. The trade-off between convenient connections and airport
congestion, showing that a higher layover cost leads an airline to reduce layover time by concentrating its
flights. In order to describe how airports’ on-time performance (OTP) relates to each other geographically,
we typically model an outcome variable that measures the airports’ on-time performance as a function of
the explanatory variable – connectivity, most commonly in a regression type of framework. When seeking
to establish the association in a regression model between the OTP score and connectivity, we implicitly
assume that the geographical or spatial locations of the observations in the analysis do not matter.
The study deals with the spatial dependence problem in linear regression analysis. This spatial patterning
– spatial autocorrelation – may be treated as useful information about unobserved influences, but it does
challenge the application of methods of statistical inference that assume the mutual independence of
observations. In addition to characteristics of individual airports, the infrastructure to support better
on-time performance in one airport are not independent of whether neighboring airports have better OTP
or not. We are suggesting that there is feedback among proximate airports that influences their
connectivity and OTP. What is the definition of neighboring airports? Are high connectivity levels
requisites for better OTP or worse OTP? What is the average value of OTP in the neighbors of the Kansai
International Airport (KIX)? Are these average values of neighboring observations correlated with each
airport's own score on OTP or connectivity?
2. Expected Results/ Conclusion/ Contribution
We have seen that the distribution of OTP displays spatial clustering in the sense that airports are more
likely to have higher values on the OTP score if they are surrounded by airports that also have high levels
of OTP. Although some of the clustering in OTP obviously could be due to spatial clustering in
connectivity, which in turn is positively related to OTP, we have shown that the spatial clustering in the
OTP data does not completely disappear when we condition on an airport’s level of connectivity. Given
that the distribution of OTP still displays spatial clustering after conditioning on an airport's connectivity,
we should look for possible ways to incorporate this spatial dependence in our previous regression model.
Keywords: On-Time Performance (OTP), Connectivity, Spatial Lag

Abstract
Silicon (Si) nanostructures, in combination with one dimensionality and nanoscale features, have been
intensively studied for various applications. To engineer the Si nanostructures for practical devices, the
well controllability over dimensions and geometries has found to be essential, which is especially
applicable in fabricating the miniaturized devices and even bridging the realization of commercial
products. Herein, in this study, the controlled fabrication of nanostructured Si was demonstrated using the
wet chemical etching process, allowing the realization of diversified geometries of Si, such as nanopores,
nanobelts, straight/zigzag nanowires and others. These intriguing Si nanostructures enable different
properties from the bulk Si, including luminescent and photocatalytic characteristics, which will be
addressed in this talk. Moreover, we explored the impacts of texturized structures on the photovoltaic
performances of solar cells, and the results revealed the efficiency of nanostructure-based hybrid solar
cells could be improved by reducing the defective sites essentially arisen from the contact
non-uniformities between organic p-type layers and inorganic n-type nanostructures. Such hybrid designs
exhibited the improved conversion efficiency with 1.8 times greater than that of untexturized solar cells.
This approach allowed providing a unique opportunity for the understanding of nanoscale etching on
silicon which remained unclear from the existing techniques and related studies.

Abstract
In the thermal power plants, failure due to Type IV creep damage has occurred in high temperature steam
pipes made of Mod.9Cr-1Mo steel and a remaining life evaluation method is required. The purpose of this
research is to establish a simple method to estimate initiation rate, growth rate and initiation start time,
and to propose a new remaining life evaluation method. In this study, creep test is carried out with
notched test piece made of simulated fine grain heat affected zone (FGHAZ) of Mod.9Cr-1Mo steel.
Shape of test piece with high stress Triaxiality Factor (TF) that can be used in single axis creep test
machine was selected by FEM analysis. The damage test piece was observed with optical microscope.
The number density of voids with certain radius were measured. From them, the initiation rate of voids,
the growth rate of voids and the initiation start time of voids were calculated.

Abstract
Type Ⅳ creep damage of high chromium steel is a problem in high temperature steam piping of thermal
power plants, so a remaining life evaluation method is required. The grain boundaries of Fine Grain Heat
Affected Zone (FGHAZ) in the modified 9Cr-1Mo steel are intricately complicated immediately after
welding, but as the creep progresses, the recovery and recrystallization of the crystal grains proceed, the
grain size increases and the grain boundary become a simple shape close to a straight line. Although the
average grain size is an indication of recovery and recrystallization, it is a relative damage evaluation
because the initial value and the value at creep rupture are unknown. Therefore, we studied on using the
fractal dimension of grain boundary as an absolute indication. First, a creep test of a round bar specimen
having a notch was conducted to reproduce Type IV creep damage. We measured the fractal dimensions
at several different locations. Next, we obtained distribution of principal stress, von Mises stress, stress
triaxiality factor (TF) and creep strain of the test piece by FEM analysis. Then, the distribution of creep
damage was calculated with the time fraction rule. We compared fractal dimension with the maximum
principal stress, von Mise stress, triaxiality factor, creep strain and creep damage to confirm the
correlation between them.

1. Background
Diabetes mellitus has become one of the most significant health concerns in recent years [1]. Among them,
monitoring the daily blood glucose level has been considered an important issue of medical treatment of
diabetes. The above reasons illustrated the importance of development of analytical strategies for
detection of glucose with high sensitivity. In this study, we reported a facile green approach for the in situ
growth of silver nanoparticles (AgNPs) on the surfaces of carbon nanodots (CND). The AgNPs/CND
hybrid nanostructures possessed the ultrasensitive sensing capability of detecting glucose contents. It was
known that Glucose oxidase (GOx) could specifically catalysze the oxidation of glucose in the presence
of oxygen to form H2O2. We combined such reaction with the AgNPs/CND hybrid nanostructures for
providing the highly sensitive detection of glucose, and the sensitivity could reach at human blood
glucose level (4-7mM) [2].
2. Results
The result of H2O2 detection was illustrated in Figure 1(a), it showed that the absorption spectra of
AgNP/CND hybrid nanostructures could function as a sensitive detector for monitoring H2O2
concentration with the concentration range of 0-100 μM. The absorption band was noted at 400-410 nm, a
characteristic absorption of AgNPs due to the surface plasmon absorption. There was a phenomenon in
which the concentration of H2O2 and the characteristic absorption simultaneously decreased, as shown in
Figure 1(a). Moreover, a linear calibration line (R2 = 0.9846) was plotted by comparing the decrease of
absorbance (%) versus H2O2 concentration (μM). It was clearly shown that AgNP/CND hybrid was
ultrasensitive to H2O2 and it provided a recorded detection limit of 10 μM. The glucose detection was
illustrated in Figure 1(b), where it showed the absorption spectra of AgNPs/CND hybrid nanostructures
could efficiently detect the glucose detection with the concentration of 0-600 μM. The linear calibration
graph was achieved by plotting the decrease of absorbance (%) versus glucose concentration (μM) (R2 =
0.9233). It could be noted that the detection limit of glucose could reach 50 μM. The facile preparation of
AgNPs/CND hybrid featuring the highly sensitivity in detection of glucose was confirmed in this study.

*E-mail: [email protected]
1. Background/ Objectives and Goals
Timing offset estimation is one of the most important technical issues in orthogonal frequency division
multiplexing (OFDM) that has attracted much attention in various wireless applications, since a timing
estimation error could cause a severe signal-to-noise ratio (SNR) degradation. Although various timing
offset estimation schemes [1]-[3] have been proposed, [1] performs poorly under the influence of the
multipath fading, since one of the correlation peaks of the delayed paths can often be mistaken for the
correlation peak of the first path, and [2] and [3] presenting a threshold test and a normalization technique,
respectively, exhibit a serious degradation in performance when the first path suffers from severe
attenuation. In this paper, so, we propose a novel two-step OFDM timing offset estimation scheme: We
first obtain an initial estimate of the timing offset by finding a timing index maximizing an impulse-like
correlation function, and then, we estimate the timing offset by observing the statistical change of the
correlation function in the timing region around the initial estimate. Numerical results show that the
proposed timing offset estimation scheme offers an improvement in performance over the conventional
schemes.
2. Expected Results/ Conclusion/ Contribution
Fig. 2 shows the mean squared error (MSE) performances of the proposed and conventional schemes with
the following parameters: , the cyclic prefix length of 8, the carrier frequency offset of
0.1, and a multipath Rayleigh fading channel with an 8-path exponential power delay profile. From the
figure, the proposed scheme provides a better performance than those of the conventional schemes. This
is because the proposed method is based on the statistical information obtained from the multiple
correlation peaks, unlike the conventional methods employing the single correlation peak of the first path.

Abstract
In this study, the influence of illuminance and infrared on light sensors and color sensors used for
educational robots was examined. Main results obtained in this paper are as follows: (1) The light sensor
is susceptible to illuminance changes, and the higher the illuminance is, the more difficult it is to
distinguish between white and black colors. (2) It was confirmed that the color sensor cannot identify
colors correctly if it was irradiated with infrared at close range. The color sensor used in the experiment
identifies colors by frequency changes of reflected light from objects which irradiates from LED. (3) It
was experimentally verified that the influence of illuminance and infrared cannot be ignored in robot
competitions such as line trace. (4) The senior school teams which had received the education have won
national competitions in WRO fifteen years in a row and participated in international competitions in
WRO held in different countries on behalf of Japan. The senior school teams have won international
competitions in WRO eleven times up to the present. Students who had received the education to examine
the accuracy of the robot sensor obtained excellent results in the robot competitions.

Abstract
In a wireless communication system, frequency offset is one of the main problems and it should be
corrected at the receiver before the data processing algorithms applied to the received signal. Frequency
shift which is known as Carrier Frequency Offset (CFO) is generally introduced by the dynamic
environment conditions in the wireless communication channel. In this study, we proposed the
time-domain Cyclic Prefix based CFO estimation method and apply this method to the Filtered OFDM
(FOFDM) signal in the wireless channel. FOFDM is one of the good candidates for the next generation
5G communication systems. According to the simulations the received signal with the corrected CFO has
a good frequency synchronization and gives perfect Bit Error Rate (BER) results.

Abstract
Several student retention theorists have purported unique models to support First Year Engagement
theory. The scholarly contributions of Vincent Tinto (1993), Alexander Astin (1984), and Carol
Goodenow (1993) inform much of the literature. Astin (1984) provided an extensive foundation of
knowledge of the factors that contribute to academic and social engagement. Similarly, Tinto’s (1993)
research addresses the role of student engagement in relation to student persistence and Goodenow (1993)
discusses how a sense of belonging contributes to student success. However, with all this knowledge, first
year experience programs are not consistently achieving desirable results and colleges and universities
struggle to retain admitted students. This proposal utilizes the existing theoretical underpinnings
connected to first year experience to reveal the need for a more robust examination of the first year
experience and deeper investigation of factors that support and thwart student success and persistence and
ultimately propose the first comprehensive first year engagement theory.

1. Background/ Objectives and Goals
The internationalisation of research activities has been occurring relatively rapidly in the university
ecosystem. Addressing global sustainability issues is a part of strategies in enhancing international
research collaboration in universities. With significantly increasing awareness in polar (Antarctic and
Arctic) sustainability issues across the globe, along with the extensive history, and interest of international
research collaboration among universities and other higher education institutions - it is timely to explore
how regionally focussed scholarly endeavours, using the case of polar research, can contribute to a robust
foundation for the internationalisation dimension of a national higher education agenda.
2. Methods
This study implements qualitative research techniques, and operates at two analytical levels of analysis
which are internationalisation of university in the context of research, and the relative contribution of
tangible and intangible values from the polar research programme in the context of internationalisation.
3. Expected Results/ Conclusion/ Contribution
The key results of the study include exploring the importance of the international dimension of polar
research conducted in universities, by bringing to attention the values of mobility, co-authorship,
international network, global citizenship and knowledge diplomacy. This study sheds light on the theories
and lends a new body of fundamental social knowledge related to the internationalisation of research
strategies in university through polar research initiatives. Besides, this study explores a discipline more
thoroughly to generate specific hypotheses that can be tested in future empirical studies.

Abstract
In modern societies, education has become critical for both individuals and governments. From the
individuals’ perspective, education is not only critical in their seeking of jobs and attainment of social
status, but also is a key determinant of their personal success. From the governments’ perspective,
education produces professionals for the industries and nurtures leaders for the society. Given the rapid
development of the logistics industry in China and Hong Kong and the increasing demand for logistics
professionals with degree qualifications, the government, industry and education institutions are looking
for practical means to attract more logistics students below degree level to further their degree study,
thereby becoming logistics professionals. This paper reports a study that examined the factors
determining intention of logistics students below degree level to further their degree study using the
theory of reasoned action (TRA) model. A total of 81 logistics sub-degree students from a Hong Kong
university participated in the study. The results identified attitude, job security, aptitude and difficulty of
curriculum as important factors that determine logistics students’ decision to further their degree study.
Based on the findings, this paper offers some recommendations to the government, industry and
education institutions to encourage logistics students below degree level to further their degree study.

Abstract
The Information and Communication Technologies (ICT) are digital forms of communications. With the
fast-increasing transmission rate of Internet, the use of ICT in the daily activities of human life for all
sectors cannot be overemphasized. The Singapore government gives great recognition to the prominent
role ICT plays in education by allocating substantial fund to help all schools to set up good standard and
suitable educational technology settings. However, one of the most deciding factors to whether ICT can
be appropriately and effectively integrated into schools’ curriculum is teachers’ ICT skills beside their
subject content knowledge. In this study, we identify the required software, hardware, and support for
pre-school teachers. We also identify the ICT skills that pre-school teachers should have. This study used
questionnaire survey and interview to collect relevant information for the investigation.

1. Background
Superabsorbent gels as a three-dimensional network formed from both linear and branched polymers are
proficient of absorption and retention numerous kinds of liquids such as bodily fluids and blood solutions.
Recently, commercial superabsorbent gels are mainly produced from polymers derived from fossil as a
non-renewable and non-biologically degradable. Therefore, in this work, a novel superabsorbent gels
mainly produced from high purity and biodegradable polymer as bacterial cellulose (BC) was developed.
2. Methods
The preparation process of this superabsorbent gels was divided into 3 steps as a follow. Firstly, BC was
modified via carboxymethylation reaction to present carboxyl group onto their chains as carboxymethyl
bacterial cellulose (CMBC) in order to well disperse in the alkaline aqueous medium. Secondly, the
pendant group as double bond was then introduced where the CMBC was reacted with glycidyl
methacrylate (GMA). In the final, the superabsorbent gel was obtained when CMBC containing pendant
group was crosslinked with polyethylene glycol diacrylate (PEGDA) via radical polymerization in
alkaline aqueous solution. The the carboxyl group content, superabsorbent gel morphology and chemical
structure were then characterized by back titration, scanning electron microscopy and Fourier transform
infrared spectroscopy, respectively.
3. Results
We have successfully prepared superabsorbent gels using BC as the main component. It was found that
both the a carboxylic group content and crosslinker used influenced both the polymer network and water
retention value (WRV) of the superabsorbent hydrogels. The superabsorbent hydrogel with the optimal
condition of the use of crosslinking 5 wt% of CMBC-g-GMA with 2 wt% PEGDA represented the
eequilibrium WRV of 125 g/g hydrogel in distilled water at water absorption rate reaching 80% of the
total swelling capacity in 30 min. Due to the green nature of BC with inherent properties of high purity,
biodegradability and sustainability, the BC-based superabsorbent hydrogels may potentially find new uses
in hygiene, food, agricultural and pharmaceutical products.

1. Background
Heat storage materials have been attracted for a wide range of application such as air conditioning,
agriculture and textiles. The utilization of these materials was developed by the encapsulation. There are
many encapsulation techniques for the preparation of heat storage material microcapsule. The
microsuspension polymerization is one of the most popular techniques because of high encapsulation
efficiency. Therefore, in this work, it was then selected for microcapsule preparation. Some parameters
influenced on morphology and thermal properties of the encapsulated heat storage material were studied.
2. Methods
The methyl methacrylate (MMA)-based microcapsule encapsulated Rubitherm 27 (RT 27) used as heat
storage material was prepared by microsuspension polymerization. The solution of oil phase consisting of
MMA, crosslinked comonomer, benzoyl peroxide (initiator) and RT 27 was mixed with polyvinyl alcohol
aqueous solution. Thereafter, the mixture was homogenized to form monomer droplets dispersed in
aqueous phase. It was then polymerized at 80 C for 8 hours. The influence of crosslinked comonomer
type as ethylene glycol dimethacrylate (EGDMA), trimethylolpropane trimethacrylate (TRIM) and
divinylbenzene (DVB) on the microcapsule formation was investigated at various ratios of MMA:
crosslinked comonomer.
3. Results
In this study, three kinds of crosslinked comonomer as EGDMA, TRIM and DVB were used to
copolymerize with MMA as main monomer. In addition, various ratios (0:100, 30:70, 50:50, 70:30 and
100:0) of MMA: crosslinked comonomer were also studied. In the cases of MMA copolymerized with
EGDMA and TRIM, nonspherical microcapsules with low shell strength were formed. In contrast, using
MMA: DVB at 70:30 wt% exhibited the best result. The nonspherical microcapsule with high shell
strength was obtained. Furthermore, the latent heats of crystallization and melting of the encapsulated RT
27 were approximately 140 J/g-RT 27 closed to those of the original RT 27. The obtained copolymer
microcapsule with good thermal properties could be potentially used in various heat storage applications.

Abstract
Thermal batteries are operating temperatures using pyrotechnic heat pellet reaction melts the solid
electrolyte to activate the battery. To activate the battery, the heat pellets are ignited by heat paper. The
ignition process therefore depends on the combustion of the heat paper, which is sensitive to pyrolants
properties. Changes in these factors due to manufacturing variance, In this paper, we prepared metal
particles + metal oxide particles with energetic polymers as binder and investigated the characteristics of
heat papers such as calorimetric value and fabricated. Results show that during combustion, the
calorimetric value of Zr/BaCrO4 with nitrocellulose were increased. And the tape casting process can
have any desirable shape and size suitable for the operation. Therefore, the heat paper prepared were
stably ignited, burned and the combustion becomes efficient.

1. Background
Thermoplastic elastomers (TPE) typically classified into six generic classes of commercial TPEs;
Styrenic block copolymers(TPS), Thermoplastic polyolefin elastomers (TPO), Thermoplastic
Vulcanizates(TPV), Thermoplastic polyurethanes(TPU), Thermoplastic copolyester(TPC), Thermoplastic
polyamides(TPA) and Not classified thermoplastic elastomers(TPZ). The greener and higher performance
of TPE could be achieved by reinforcing with natural fiber. The flexural strength of TPU was enhanced
by adding the Hemp fiber [1]. The utilization of cellulose nanocrystals (CNCs) as a reinforcing material
in TPE was reported [2]. It was found that Tg and tensile strength was improved by adding CNCs.
Development of TPE reinforced with Kenaf fibre(KF) was also studied [3]. Two types of impact modifier,
thermoplastic natural rubber (TPNR) and polypropylene/ethylene propylene diene monomer (PP/EPDM),
were used. The present of KF and maleic has significantly increased the tensile strength of the PP/EPDM
composite while only less increment attained in TPNR system. In this work, the micro cellulose(MC) was
employed to reinforce the green TPC based on Poly(carbonate)(PC)/Poly(butylene succinate)(PBS)/
epoxidized natural rubber(ENR) blends. The mechanical enhancement without scarifying the elastomeric
characteristic was the main aimed.
2. Results
Table 1 summarizes the tested properties of green TPE/MC composites. With increasing the MC content,
the lost of impact strength but increasing in the tensile properties was observed. The tensile resilience
testing indicates the elastomeric characteristic of the green TPE composite.
At 40 g of MC in ERN compound, by increasing the ENR loading in the green TPE composite, it was
found that The impact strengths were in upright trend with good tensile elastic properties. The lost in
tensile properties due to the resilience tension load were minimal. ENR content at 100 g was
recommended for manufacturing the green TPE/MC composite. By employing the bentonite as
filler/colorant in the TPE manufacturing, it was found that the bentonite act as thixotropic filler. However,
it had no significant effect to the mechanical properties, especially tensile characteristics, of the TPE/MC
composite.
Fig. 2 show the selected SEM photos of PC/PBS blend and green TPE/MC composite at 60 g of MC
content, respectively. It is seen that there is no major phase separation between PC and PBS in the blend.
At 60 g of MC in the TPE matrix phase, it is visualized that the micro fiber is well dispersed in the matrix
phase. Also, good interfacial adhesion is apparently observed.

Abstract
The International Roughness Index (IRI) is the standard roughness index of pavement management
employed to acquire quantitative longitudinal surface-bump data of road profiles. It is a calibration of
road roughness measurement by using a quarter-car vehicle math model. The main purpose of this paper
is to closely examine correlations between the data profile of IRI and longitudinal surface-bump data and
explain mechanism in terms of physics by employing Lagrangian dynamical approach. The
conventional definitions and a new profile to define IRI is proposed.

Abstract
In real life, managers often have to face a variety of decision-making problems. Among them, the theme
of multi-criteria decision making (MCDM) is one of the most important and complex issues in the
decision-making field. In general, the elements of MCDM can be composed of three parts: input, output,
and solution. The input is expressed as m scenarios with n criteria. It usually assumes that the underlying
input data can be represented in a decision table. Accordingly, the output is the optimal result or set of
results that are resolved by different types of solution methods. In this study, we present a summary
technique that displays decision tables as new summary tables; allowing managers to make decisions
faster. The proposed technique is to optimize the results of the summarization, that is, to minimize the
loss of information. Since finding the minimum result is a NP-hard problem, we apply a genetic algorithm
to improve the summary results.

Abstract
In the regular work process of peer review, editors have to read and understand the entire set of
submissions to choose appropriate reviewers. However, due to a large number of submissions, to select
reviewers manually becomes error-prone and time-consuming. In this research, a framework that
considers different indispensable aspects such as topical relevance, topical authority and research interest
is presented and, an integer linear programming problem is formulated with practical considerations to
recommend reviewers for a group of submissions. Specifically, the topical relevance and the topical
authority are utilized to recommend relevant and accredited candidates in submission-related topics, while
the research interest is to exam the willingness of candidates to review a submission. To evaluate the
effectiveness of the proposed approach, categories of comparative experiments were conducted on two
large scholarly datasets. Experimental results demonstrate that, compared with benchmark approaches,
the proposed approach is capable to capture the research interest of reviewer candidates without a
significant loss in different evaluation metrics. Our work can be helpful for editors to invite matching
experts in peer review and highlight the necessity to uncover valuable information from big scholarly data
for expert selection.

Abstract
In this digital era, protecting secret data has been an essential factor. This protection can be done by
implementing various methods, such as data hiding. However, there are some problems in that scheme,
such as the limitation of the amount of the secret which can be protected. Indirectly, this relates to the
quality of the generated stego data. In this paper, we introduce the multiple peaks-based histogram
shifting method for protecting data. In this case, we divide the secret data according to the number of
corresponding peaks. The experimental result shows that the more peaks used for embedding data, the
more decrease the quality of stego data. However, this reduction is getting smoother along with the
increasing the number of peaks. Furthermore, we also find the optimum number of possible peaks to use
without much reducing the quality of the corresponding stego image.

Abstract
Due to the popularity of the Internet of Vehicles (IoV), many malicious packets may enter to the internal
network of a car from the Internet or telecommunication network. It is difficult to update the Internet of
Things (IoT) system into the newest version because most of IoT devices are low-powered and their
memory sizes are small. The hackers place the Trojans or backdoors through the known vulnerability by
scanning the system information. Therefore, our study focuses on the probing attacks and prevents such
situations. We provided a lightweight intrusion detection system with machine learning technology to
improve the detection of the malicious flows.

Abstract
In Educational Data Mining (EDM), classification is one of the crucial tasks to obtain a better education
environment. Support Vector Machine (SVM) has been among popular classification algorithms.
Nevertheless, there is still no further research about how to improve the performance of SVM. In this
paper, we focus on this issue. That is, how the enhancement of classification performance of SVM using
kernel selection on student’s cognitive domain should be performed. Here, kernel explored consists of
four kernels, namely: linear, polynomial, RBF and sigmoid. The experimental result indicates that the best
performance of SVM is achieved when linear (SVM_Linear) is applied whose accuracy level is about 84
%. On the contrary, the lowest of accuracy level is reached by polynomial (SVM_Polynomial), which is
about 63%. The other kernels: RBF (SVM_RBF) and sigmoid (SVM_Sigmoid) gain the same level of
accuracy, which is around 76%.

Abstract
Automatic Number Plate Recognition (ANPR) is an approach that adopts Optical Character Recognition
(OCR) and other image processing techniques (e.g., image segmentations and object detection) to read
vehicle registration plates. In order to get an efficient, smart and powerful system, ANPR software should
operate in real time. In recent years, the rapid increase in programmability of graphic processing units
(GPUs) has enabled us to get real time speed when implementing license plate segmentation. In order to
clarify the rate of time acceleration while observing the accuracy of the system, GPU techniques have
been widely used to obtain real time during implementing license plate segmentation, and to compare the
parallel system against the serial system. In this paper, an efficient algorithm has been presented to get all
advantages of License Plate Segmentation (LPS). More specifically, we propose a new methodology for a
powerful parallel OCR framework for LPS using GPUs with Compute Unified Device Architecture
(CUDA). Our proposed parallel GPU approach can be equally applied to Egyptian case and can also be
extended to cover more similar countries that employ the Arabic language. It is based on keeping the
names of these countries along with a list of Arabic characters as entries in a table; such these entries
could be matched parallel with the car plate.

Abstract
Tracking and detecting of moving object has obtained an eminent importance reason to impetuous
technological advancement in the field of computer science in Video Surveillance System. Human motion
is generally nonlinear and non-Gaussian and thus many algorithms are not suitable for tracking. One of
the applications to maintain universal security is crowd control. The main problem of video surveillance
is the ability of the monitoring officers with regard to crime detection. For security monitoring of live
surveillance systems, target identification and tracking strategies can automatically send warnings to
monitoring officers. In this paper we propose a robust tracking method to tracking the specific person and
detecting all human area in Video Surveillance System using the individual’s feature. The proposed
method to determine automatic detection and tracking combines Histogram of Oriented Gradient (HOG)
feature detection with a particle filter. The Histogram oriented Gradient features are applied for single
detection window for the identification humans area, after we use particle filters for robust specific people
tracking in the video surveillance systems by using colour and skin colour based on the characteristics of
a target individual. We have been improving the implementation, evaluation system of our proposed
methods. From our experimental results, we have achieved high accuracy detection rates and tracking
robust specific target objects.

Abstract
There are machine observation and human observation methods for the traffic volume survey problem.
However, it is difficult to classify car models because high accuracy machine classification is difficult.
The objective of this research is to classify car models and investigate traffic volume. In this method, we
detect a car from a moving image and use CNN to recognize it. We count the number of cars passing per
model and save the results in a CSV file. The recognition accuracy of the learning model used in this
method was about 59 %.

Abstract
Employers currently encounter more and more members of Generation Z - who finished their school as well
as university education - without knowing exactly what this generation wishes and needs. This paper
verifies current assumptions about Generation Z with a quantitative study, consisting of two parts. As a first
step, members of Generation Z (n = 103) were queried upon their work attitudes while in a second step,
company representatives (n = 48) were asked about their assumptions on the adolescents’ preferences.
Thus, not only conclusions on young adults could be drawn, but also on the (lack of) knowledge about
Generation Z of their employers. The prior assumption that the young generation would be difficult to
employ inter alia due to their refusal of a work-life blending, lacking career orientation, and inability to take
feedback could not be supported. In fact, Generation Z seems to be committed as well as motivated to work
for their professional success. Employers showed a decent understanding of their young employees, though
there seem to be a couple of misapprehensions.

Abstract
A manager makes inventory decisions based on inventory evaluation. There are two evaluation schemes.
One is end-of-period evaluation which assesses inventory periodically. The other is continuous evaluation
which calculates inventory-related cost as it accrues continuously over time. While it is known that
end-of-period evaluation leads to overstocks at the most downstream installation, it is not clear how it
affects an upstream installation. This paper compares decision-making under the two evaluation schemes
for a two-stage serial inventory system. It is found that end-of-period evaluation leads to overstocks at the
upstream installation as well. Thereafter, the consequence of mistakenly using end-of-period evaluation is
examined in terms of cost. This paper aims to discover a connection between results found under the two
evaluation schemes and facilitate a manger’s decision-making.

Abstract
Corporate Social Responsibility (CSR) is one of the most important corporate strategy for enhancing
competitive advantages and sustainable development of business. In the study, a case analysis and
in-depth interview were arranged with well-known international aviation corporate – Cathay Pacific; to
identify and evaluate the revised model on CSR practice in the sector.
In general, the interviewee provided valuable views and examples aligned with the revised model. The
findings would be helpful for filling the literature gap and provides a foundation for further studies of
CSR practices in other sectors / industries. The limitation of this research is that it only focuses on
qualitative research (i.e. personal interview and case study). Future research should be applied with
quantitative approach using a large sample of companies in order to generalize results.

Abstract
Based on an online questionnaire survey targeting at employed people from more than 10 provinces of
China, this paper investigates the distribution of hours mismatch among different social classes, trying to
give answers to two questions: which class is more overworked? How to reduce the sense of being
overworked with different kinds of job rewards, and whether the influences of job rewards differ in social
status? We find that although middle-class people are more likely to feel overworked, they have the
smallest hours mismatch; people at the lower status suffer the greatest discrepancy between actual and
preferred hours; the effects of both intrinsic and extrinsic rewards decline when social status moves up;
organizational efficiency as a kind of rewards makes elite people feel more overworked.

Abstract
Empirical studies of social network analysis have provided sufficient evidence to support the general
claim that high-centrality individuals in social networks outperform those with low centrality. We device
arguments from theories to question this claims and identify the needs for taking reversed causality into
consideration when examining the centrality-performance relationship. It is puzzling that previous studies
have assume causality only in one direction from centrality to performance, but not the reverse. The
possible origins of the endogeneity are discussed. Furthermore, the study reexamine the
centrality-performance relationship in the context of movie directors’ networks and box-office
performance. Our findings show that all measures of centrality significantly affect the outcome variable
when the method of instrumental variables is applied to address the proposed reversed causality.

Abstract
The number of street food vendors in Indonesia is enormous. Many of them sell their products on
semi-permanent stalls, while others moving around the residential area with their food cart. It is widely
known that sometimes their food hygiene is questionable. This study aims to acquire the knowledge level
of those street food vendors about food safety practices. The study was conducted in Bandung,
questionnaires were given to 300 respondents who were street food vendors. They were spread in three
areas where street food vendors were concentrated in bandung. After the data were collected They were
analyzed descriptively. The result showed that street food vendors still not aware of some important
knowledge related to food safety. It is proven that they have already known common knowledge about
food safety practices. However, they still need to improve more advanced knowledge in regarding food
safety practices. One of the most important findings of this study is that their knowledge about
government regulations of food safety is relatively low. This study is expected could become one of the
references for the government to give training and education program for street food vendors.

1. Background
Obstacles detection and avoiding abilities are very critical to achieving autonomous flight for commercial
unmanned aerial vehicles that have been widely applied to various applications, such as inspection,
surveillance and transport. There are some commonly-used approaches, like infrared, ultrasonic and
vision-based methods, for detecting and localizing obstacles in a real space, but all of them are with
disadvantages while being employed outside. Therefore, this study introduces a monocular vision based
depth sensing system by combining deep learning and LiDAR technologies.
2. Results
A great quantities of image correspondences that captured from a ZED camera are first collected to be the
dataset of training and testing. In order to compute the depth from disparity, the camera calibration is
necessary for obtaining intrinsic and extrinsic parameters. Thus the depth can be easily calculated by the
disparity, focal length and stereo baseline. However, a low-cost camera is only used in our application
scenario and there is no baseline in our work. A function of transforming disparity to depth must be
urgently needed. Here, a simple linear regression model is employed, where the disparity values are
estimated and the depth values are from a laser ranger finder, respectively. Fig. 2 shows the linear
regression curve. In the experiments, we have implemented the proposed system on an embedded
platform, as shown in Fig. 3, which contains the flight controller, Raspberry Pi, a camera, a LiDAR lite,
and a neural computing stick. Fig. 4 shows the depth sensing results, where the left image is the original
captured image on a drone and the right one is the estimated depth.

1. Background
Crinum thaianum (water-onion) is a native aquatic plant in the south of Thailand. It is in the family
Amaryllidaceae. Its leaves are extremely tough, making it suitable for aquariums with large fish.
Water-onion during blooming season in Ranong and Phangnga Provinces used to be a tourist attraction
site many years ago. At present it is classified as an endanger species due to the illegal digging for
exportation and the upstream destruction. These practices can lead to the reduction of water-onions.
No genetic information on water-onion has been reported. It will be good to have genetic information of
this endanger native species of Thailand for species specific identification and for evaluation of genetic
variations for conservation practices and sustainable uses.
2. Methods
Microsatellite (MS) markers were developed from the enrichment genomic library of water-onion. The
usable markers were used for genotyping of all water-onion samples. Moreover, DNA sequencing of
water-onion were performed at the ITS of rDNA (nuclear-encoded) and rbcL, matK, trnH-psbA intergenic
spacer (plastid-encoded) regions. The sequences were compared to the other crinum plants used as out
groups.
3. Results
Fifteen out of 28 MS markers were successful in amplification the specific target. DNA sequences in each
region were generated in out groups and 5 samples of water-onions collected from different locations in
Ranong and Phangnga Provinces. Crinum thaianum samples are still grouped together even though they
are in different locations. Therefore these four regions can be used as a marker to classify Crinum
thaianum from Crinum plants. For the future works, more MS markers will be developed. The
information obtained will be useful for specific identification of water-onion, the endanger species.

1. Background
Sensors are devices that respond to chemical, physical and biological stimuli, resulting in the production
of a signal that provides a quantitative measurement of the stimuli. We need sensors for monitoring
structural integrity of reactor containment buildings and nuclear waste repository, control of nuclear
power plants, pollution monitoring and leakages of toxic gases/chemicals[1-2]. The main objective of the
present work is to develop ion selective electrode sensors based on PVC membrane by incorporating
Schiff base ligands and their complexes, macrocyclic ligands as ionophores for sensing different metal
ions. Ion selective electrodes have been prepared and the electrodes performance was optimized by
varying the amounts of PVC, plasticizers and cation/anion excluders. Various characteristic features of
these proposed chemical sensors with different parameters such as response time, selectivity, lifetime and
pH effect on sensor response have been studied. The semicarbazide and thiosemicarbazide based Schiff
base ligands and their metal complexes have been synthesised and used for the fabrication of
electrochemical sensors or ion- selective electrodes. The proposed ISEs were successfully applied for the
determination of various cations and anions in water samples and also as an indicator electrode in
potentiometric titrations.
2. Results
The response of different metal ions and rare earth ions were plotted as the negative log of concentration
and the potential values obtained for different metal ions. The different membrane ingredients, such as
amount of ionophore, amount and nature of the plasticizer and additives influence the potentiometric
response behaviour of the sensor [7, 8]. The proposed electrochemical sensor exhibits a fixed membrane
composition and can be used to determine Pb2+
ion concentration in solution. The electrode works well in
a relatively wide, independent pH range and exhibits a fast response time, high sensitivity and selectivity
for Pb2+
ions. The life time of the electrode was 8 weeks. The proposed electrode was successfully applied
to the determination of lead in water samples by indirect potentiometry.

Abstract
The objective of this research is to apply the artificial neural network method to forecast the demand for
alum and chlorine, which are the main chemicals used in the water treatment process of Bangkhen water
treatment plant. The forecasting models are developed from monthly chemical consumption amount data
from October 2008 to September 2015 to forecast the monthly chemical demand amount during October
2015 to September 2016. Turbidity, dissolved oxygen, oxygen consumed, conductivity and pH are used as
the input variables of the models and selected by stepwise regression. The results show that the
appropriate structure for the artificial neural network, which provides the minimum forecast error for
alum, is one hidden layer with a number of neurons in the hidden layer – the output layer equals to 20–1.
The corresponding transfer functions are purelin–logsig. For chlorine, the proper structure is one hidden
layer with a number of neurons in the hidden layer – the output layer equals to 15–1. The corresponding
transfer functions are purelin–logsig. The mean absolute percentage errors of the alum and chlorine
demand forecasts are 18.27% and 14.70%, respectively.

Abstract
As stated by the expansion of the railway systems in Thailand, a great demand of construction material
especially rock aggregates, flows into the market so that the development of new material resources must
be precipitated. Chiang Mai, Thailand, contains the natural resources with high potential in developing as
material reserves for supporting raw material for railway construction, thus the investigation of the actual
resources has not been verified. In order to complement this desideratum, the combination of field
observation and geological technologies were a ubiquity for the investigation of these earth resources.
Conversely, in unapproachable area such as mountainous, the investigation using those techniques were
limited. To overwhelm those obstacles, the integrated remote sensing approach using the combination
between the observed spectrum of specific outcrop from spectrometer, Spectral Angle Mapper (SAM) and
the NDVI analysis were applied to locate the potential igneous rock outcrop within the region of Chiang
Mai, so that the further on-field investigation will consumes shorter period by straightly forwarding to
investigate the possible area. According to the study’s result, the appropriate SAM angle in classification
of biotite-hornblende granite outcrop in the inspected area were determined to be 0.35 radian with totally
3.66 km2 of the scattered potential area.

1. Background
The use of Low Intensity Pulsed Ultrasound (LIPUS) has demonstrated promising effects on articular
cartilage, especially on chondrocytes in knee osteoarthritis. However, fewer studies investigate what
extent LIPUS propagate within the knee joint space. The purpose of this study is to evaluate the
propagation properties of ultrasound over a simplified joint space model by using computer simulations.
2. Methods
The 2D computer simulations incorporate a reference model, which mimics the structure of the joint of a
human knee from a lateral view of CT image. All the simulations were performed using k-Wave, which is
an open source acoustics toolbox for MATLAB. It is designed for time domain acoustic and ultrasound
simulations. k-Wave allows the user to specify acoustic parameters, such as sound speed and density of
the medium and any acoustic source in the medium. The ultrasound transducer was modeled as a 2.0 cm
line source, which produced a 1.0 MHz ultrasound pulse. The ultrasound source was located at about 20
mm from the medial condyle. The effects of ultrasound transducer in different positions in height
direction were examined.
3. Results and Conclusion
Simulation results showed that ultrasound is capable to propagate through the simplified knee joint space
model. The amplitude of ultrasound pulse is decreased from the anterior to the posterior region of the
joint space. The amplitude of ultrasound pulse is also related to the position of ultrasound source in height
direction. Although the simulation model of this study has a considerable simplification, it is a start of
investigating the properties of ultrasound propagation in the joint space. The next stage of this study will
take into account for the heterogeneities of the articular bone structure.

1. Background
Fluorescent viscosity sensors – molecular rotors – provide one of the most convenient ways for
measuring viscosity in aerosols, model membranes and living cells.1 However, despite the increasing
usage of molecular rotors, the relation between their molecular structure and sensitivity to viscosity or to
other parameters, such as temperature and properties of the solvent is not well examined. We have
attempted to vary the molecular structure of BODIPY-C10 (Figure 1A) – one of the most popular
molecular rotors – and see how this impacts the sensitivity of the molecular rotor to viscosity, temperature
and solvent properties.2
2. Results
In this work we varied the substituents on the BODIPY-type molecular rotor, starting with heavy
electron-withdrawing –NO2 group, to electron donating –NMe2 group. The structures are shown in Figure
1B. Since BODIPY-type rotors are used to sense viscosity via their fluorescence lifetime, we have
measured the lifetimes of new BODIPY rotors at varying viscosities, temperatures and in different solvent
mixtures.
The rotor with no group (Figure 1B, middle) possessed very similar viscosity sensitivity properties to
BODIPY-C10; its viscosity-sensitive range is approximately 10 cP to 1000 cP, the time-resolved
fluorescence decays are shown in Figure 1C. In contrast, the rotor with –NMe2 group (Figure 1B, right)
was non-fluorescent. However, the rotor with –NO2 was not only fluorescent and viscosity sensitive, but
its viscosity sensitive range extended up to 50 000 cP, which makes it much more suitable viscosity probe
for high viscosity environments than BODIPY-C10. To our knowledge, this is the first fluorophore capable
of viscosity sensing in such viscous environments. Overall, this is an interesting example showing how
relatively small changes in molecular structure of molecular rotors can drastically change their properties.

1. Background
Waste generated from cattle farms is in the form of feces and cow urine. Every kilogram of milk
produced by dairy cattle produces 2 kg of cow solid waste (Sihombing, 2000). The amount of feces and
urine produced reaches 10% of the weight of livestock (Rinekso et al, 2011). Maximum capacity of PT.
Greenfields Indonesia, which reaches 10,000 cows, can produce 45 million liters of milk will produce
waste with a large enough quantity. If there is no good management of the cattle farm waste, it is feared
that there will be environmental pollution or other environmental problems that will have an impact on
human health and comfort around the area. Cow manure contains N (2.0%), P (1.5%), K (2.0%), Ca
(4.0%), Mg (1.0%) and S (0.5%) (Agricultural Research and Development Agency, 2013), and cow urine
contains up to 4.0% organic matter (Hartatik & Widyowati, 2006). These ingredients can still be used as
nutrients or plant nutrients by applying them as organic fertilizer. The objectives of this research are (1) to
determine the influence of liquid waste and solid livestock density as fertilizer on soil quality (2) to
determine the effect of liquid fertilizer on coffee plant growth (3) to determine the effect of solid fertilizer
on the growth of coffee plants.
2. Results
The results of the study showed that (1) the provision of cattle farm wastewater 1 time can improve the
C-organic chemical properties, N. total, P, CEC, Ca and Mg, while the soil chemical properties of pH, K,
Na, the amount of base and saturation of the base decreased . The C / N and Ca ratio parameters did not
change in the treatment of organic wastewater treatment once. Treatment of livestock liquid fertilizer 2
times can improve soil chemical properties pH, N total, Ca, Mg and saturation bases, while other
chemical properties of C organic, C / N ratio, P, CEC, K, Na, and base amount decline. Giving solid
waste of cattle farms 1 time can increase chemical properties of pH, C organic, N total, Ca and saturation
of base, while the soil chemical properties C / N ratio, P, KTK, K, Na, Mg and base amount decreased.
The treatment of the provision of livestock solid waste 2 times can improve the soil chemical properties
of pH, N. total, P, Ca, Mg, base number and base saturation, while other organic C. chemical properties,
C / N ratio, CEC, K and Na decrease (2) Provision of liquid waste fertilizer has a significant effect on
plant height and high rate of coffee plants (3) Provision of solid waste (compost) has a significant effect
on plant height, plant height velocity and number of buds.

1. Background
Rice is an important staple crop for billions of people. However, the cultivation usually exposed to
drought stress which is the factor that limited plant growth. The previous evidence suggested that the low
concentration of hydrogen peroxide (H2O2) plays an important role in abiotic stresses. It regulates the
antioxidant system and the other drought tolerance mechanism via ABA signaling (Saxena et al., 2016).
Although the studies about the effects of H2O2 on drought tolerance related to physiological
characteristics were well-established; however, various concentrations of H2O2 were used and the suitable
concentration for rice is not reported. Therefore, this study aimed to investigate the effects of different
concentrations of H2O2 on the physiological characteristic related to drought tolerance by foliar spray
method.
2. Results
Rice seedlings exposed to drought stress dramatically decreased RWC and total chlorophyll content but
increased EL and MDA content compared to the seedlings under well water condition. Foliar spray with
H2O2 benefits to rice seedlings by improving several physiological characteristics. It is well-known that
H2O2 act as the signaling molecule under drought stress, many mechanisms related to drought tolerance
are activated during this condition including enzymatic-antioxidant system and abscisic acid signaling.
The main antioxidant enzymes including SOD and CAT were induced under drought stress in order to
remove the reactive oxygen species. Foliar spraying with all concentration of H2O2 tended to increase
these enzymes activities compared to distilled water spraying. The similar trend was found in MDA
content and EL, the results indicated that H2O2 spraying slightly decreased the oxidative damage
compared to distilled water treatment. In addition, the advantage in improving total chlorophyll content
was found in 1-2 mM of H2O2 spraying compared to distilled water group. In summary, H2O2 plays a vital
role during drought stress by enhancing antioxidant system as well as maintaining the water content. H2O2
is involved in ABA signaling which is related to stomatal closure. This may help H2O2 treated seedlings
maintaining higher RWC. As a result, higher antioxidant enzymes activities were higher in H2O2 treated
group; moreover, the reduction of EL and MDA were observed. The results from this study indicated that
the most effective H2O2 concentration in this study was 1 mM.

E-mail: [email protected]
1. Background
In Thailand, rice (Oryza sativa L.) is one of the most important crops. It is a widely cultivated staple food
that is exported worldwide (Siriphollakul et al., 2017). However, the cultivation usually exposed to
drought stress which is the factor limiting plant growth. Many recent studies found that plant growth
regulators are extensively used to regulate plant growth and to enhance plant drought stress tolerance.
Melatonin is a biological hormone involved in many important physiological processes in plants
including the regulation of plant growth and development. Furthermore, melatonin acts not only as a
signaling molecule for enhancing the resistance of plants to biotic and abiotic stresses, but also as a
powerful free-radical scavenger and has a direct antioxidant activity (Arnao and Hernández-Ruiz, 2015).
Although effects of melatonin on drought tolerant and the role of melatonin in alleviating drought stress
has been widely described for several species, the role of melatonin in rice response to stress is still less
well known. Therefore, this research purposes to investigate the effects of melatonin on growth, some
physiological characteristics and antioxidant enzyme activities in rice under drought stress.
2. Results
The results showed that after 7 days of drought stress, rice seedling growth including shoot length, root
length, fresh weight and dry weight significantly decreased in non-treated plant (0 µM melatonin)
compared to the control. The foliar spray with melatonin benefitted to rice seedlings by increasing shoot
and root length as well as root fresh weight and root dry weight compared to non-treated plant. However,
shoot fresh weight and shoot dry weight were not barely altered from non-treated plant. Relative water
content significantly decreased in non-treated plant compared to the control, with reduction by 28%. The
application of melatonin showed relative water content of treated plant higher than that of non-treated
plant. The drought-stressed plant showed higher chlorophyll content compared to the control plant. The
foliar spray with melatonin slightly increased chlorophyll content compared to non-treated plant. Under
drought stress, the electrolyte leakage significantly increased in non-treated compared to the control,
however, melatonin treatment had a positive effect on electrolyte leakage. Melatonin decreased the
electrolyte leakage, that was lower than non-treated plant. Furthermore, malondialdehyde content, an
indicator of lipid peroxidation was not altered. In addition, drought stress increased the activities of
antioxidant enzymes such as SOD, CAT, APX and POD in rice seedling and the application of exogenous
melatonin tended to increase these enzymes activities compared to non-treated plant.

Gene Expression in the Resistant and Susceptible to Bombyx Mori Nucleopolyhedrovirus
(BmNPV) Silkworm Strains

Department of Biology, Faculty of Science, Khon Kaen University, Thailand
E-mail: [email protected]
1. Background
The silkworm, Bombyx mori, is an economically important insect group for the sericulture or production
of silk fiber, processing to silk thread and silk fabric. In addition, the two main proteins from silk cocoon,
fibroin and sericin, have been applied in pharmaceuticals and cosmetics such as wound healing,
antiwrinkle and anti aging (Yao et al., 2003). However, the major problem in rearing silkworm is
pathogenic diseases causing the cocoon crop loss (Saksung and Tawonanukulkit, 1997). One of the major
diseases is “grasserie disease” induced by Bombyx mori nucleopolyhedrovirus (BmNPV) infection.
Subsequently, many studies have reported proteins involving in antiviral mechanism in silkworm that are
Bmlipase-1, serine protease-2, lipase-1 and alkaline trypsin proteins (Ponnuvael et al., 2003; Nakazawa et
al., 2004). In Thailand, the classification of mulberry silkworm are divided into three races by their
origins that are Thai native, hybrid and foreign silkworm strains. The Thai native silkworms seem more
resistant to viruses than the foreign silkworm. However, the levels of resistance to BmNPV infection of
silkworm strain have not been reported. Therefore, the prior aim of this study is to investigate the level of
potential resistance to BmNPV infection in both the resistant and susceptible larvae strains by comparing
target gene expressions using qRT-PCR.
2. Results
Grassery disease of silkworm (Bombyx mori) caused by Bombyx mori nuclear polyhedrosis virus
(BmNPV) is one of important epidemic diseases affecting the sericulture in Thailand. This study aimed to
investigate genes expressions related to BmNPV response in silkworm. Eight strains of silkworm
including Sumrong, Nanglai, Nangsiw, Nangtui, Nangnoi, Kaki, Pangpuay and NNK8 were used in this
experiment. Total of 20 larvae of each strains were divided into two groups; the treatment group and the
control group. The treatment group, the concentration of polyhedral virus with 105 OB/ml was spread on
fresh mulberry leaf and fed the fourth instar on the first meal. The control group was fed on fresh
mulberry leaf with sterilized distilled water coating instead of viral contamination. They were reared to
the fifth instar larval then individual mid-gut were dissected for RNA extraction by TRIzol. A total
amount of extracted RNAs were between 1179.44 to 1782.93 ng/µl and the RNA purities were between
1.99 to 2.05. The cDNA was synthesized by reverse transcription and then the cDNAs were investigated
by Real-time quantitative PCR (qRT-PCR). The transcription level of Bmlipase-1 was increasingly
expressed in the Sumrong and Nanglai strains with significantly different (p<0.05) when compared to the
control group.

1. Background/ Objectives and Goals
The 2008-09 credit crisis has highlighted the importance of counterparty risk in connection with valuation
and risk management of credit derivatives. Counterparty risk in general is the risk that the party to a
financial contract may fail to make all the payments required by the contract, causing losses to the other
party. Contracts privately negotiated between counterparties like over-the-counter (OTC) derivatives are
most likely subject to counterparty risk. Modeling counterparty credit exposure for credit derivatives is
more complicated than for other noncredit products, since the reference credit and counterparty may
display some sort of default correlation. A few studies have been made to analyze the valuation of
counterparty risk within a credit default swap (CDS). In contrast, little attention has been given to analyze
the counterparty risk embedded in a basket default swap (BDS). Therefore, we take into account of
counterparty risk for the valuation of a BDS in this paper, aiming to fill the gap in the literature on the
analysis of counterparty risk within credit derivatives.
2. Expected Results/ Conclusion/ Contribution
Based on the IS algorithm proposed in the paper, we will conduct numerical analyses of the estimation of
fair spreads for k-th-to-default BDSs, and examine how the counterparty credit risk is priced in BDS
contracts. It is expected to see that the estimator for the default leg based on our IS algorithm is more
efficient than that based on naive Monte Carlo simulations. We expect that the IS estimator based on our
proposed algorithm displays a marked decrease in variance, especially when the chance of the k-th default
event occurring is highly unlikely. Finally, it is expected that our numerical results can provide evidence
about how the counterparty credit risk is priced in the market via the calculation of the CVA values.
We contribute to the literature by providing a solid basis for the estimation of k-th-to-default BDS default
legs after taking into account the counterparty risk. We expect that our numerical analyses have
implications for the debate on the regulation of derivatives markets.

Generalized Riskiness-Minimizing Hedge Ratio: Considerations of Physical Risk and
Risk-Tolerance
Jen-Wei Yang
Department of Economics, Soochow University, Taiwan (ROC)
E-mail: [email protected]
Abstract
This study proposes the generalized-riskiness-minimizing spot-futures hedge ratio which is determined by
minimizing the generalized riskiness index of the hedge portfolio return, where the generalized riskiness
index is proposed by Bali, Cakici, and Chabi-Yo (2011). Unlike the most risk indices adopted in the
previous studies, this risk index (1) measures the physical risk of an asset return as well as the
risk-tolerance of an investor; (2) satisfies monotonicity with respect to stochastic dominance. The solution
for this optimal hedge ratio are provided and can be estimated by method-of-moment. By using this hedge
ratio, the empirical findings show that the hedgers can pay smaller hedge costs to eliminate the larger
total risk (including the larger risk-tolerance-induced risk and a little bit smaller physical risk) than the
optimal hedge ratios which are determined by minimizing the riskiness proposed by Foster and Hart
(2009).

1. Background/ Objectives and Goals
In the condition of information asymmetry, mortgage-backed securities (MBS) were generally considered
as an information insensitive design with high liquidity. But a large amount of mortgage-backed securities
were in the lack of liquidity for a relatively long time during and after the subprime crisis, even some of
the securities were not in credit deterioration, which became an puzzle in academy. From the perspective
of information asymmetry, the research introduced the concept of investor confidence in theoretical and
empirical analysis, and tried to explain why the mortgage-backed securities in good quality lacked
liquidity during and after subprime crisis.
2. Expected Results/ Conclusion/ Contribution
The research found that, when the signals from the design of mortgage-backed securities, such as MBS
credit ratings, can effectively increase investor confidence, investors tend to increase the expected value
of the securities, which would decrease the volatility and increase the trading volumes, which improves
the liquidity. If the signals expose severe problems, such as the MBS credit ratings were questioned
during and after subprime crisis, investor confidence would be hurt since the investors don’t have other
more information about the securities under information asymmetry, and investors tend to leave the
market, which means, the liquidity would dry up. The results give a reasonable explanation to the
breakdown of MBS market during and after the subprime crisis. The result empirically represents as that
the bid price of mortgage-backed securities has significant excess earnings with the changes of MBS
credit ratings; when the credit ratings get upgrading, the investors tend to give higher bid price than its
expected value, which proves the existence of investor confidence in the market.

This study extends the previous papers regarding the influence of business culture over decision making
of the firm (see, for example, Hilary and Hui, 2009; Li et al., 2013) to investigate how the local culture of
the headquarter of a firm affects the corporate risk-taking behavior in mergers and acquisitions (M&As).
As tender offer has been considered as a risky takeover strategy to bidders, the US tender offer deals
during 1977-2015 are collected to examine whether the firm located in a county with higher regional
gambling preference will be more possible to adopt the riskier tender offer strategy and how such regional
cultural factor influences the short-/long-term performance of these bidders.
Using US merger and acquisition data during 1977-2015, the empirical results show that the higher the
gambling preference of a region is, the more possible an acquirer headquartered in this region chooses
tender offer strategy in its merger, and the higher price it is willing to pay. Although the short-term
announcement effect of tender offers across regions are statistically indifferent, it is also found that the
acquirers headquartered in the regions with higher gambling preferences have significantly higher returns
in the long term, regardless of whether the cumulated abnormal return (CAR) or other market-based
measures are used. These results are robust and consistent with early studies in that the culture of a region
do change the risk attitudes of the firm headquartered there to corporate decisions and strategies,
including tender offer.

Abstract
Laboratory experiments were perfumed to determine the rates of processes responsible for the recovery of
dissolved oxygen (DO) in an embayment connected to a main channel. We measured the horizontal
velocity vectors to evaluate large-scale circulation within the embayment and measured the time series of
DO concentrations during the recovery processes promoted by supply from the main channel. The present
study highlights the influence of the aperture ratio of the embayment/main-channel opening. and finally,
it was found that DO recovery rate is controlled by the bulk-mean velocity in the main channel, the
aperture ratio, and the position of the embayment opening.

Abstract
Headspace solid-phase microextraction (HS-SPME) was developed for extraction of organic acid
preservatives, which are benzoic acid, sorbic acid and propionic acid, in fruit juice and analyzed by gas
chromatography with flame ionization detector (GC-FID). The 85 µm polyacrylate coated fiber (PA) was
used to extract the analytes from headspace of 10 mL sample solution and were desorbed by thermal
desorption at 250 oC in the GC injection port. The optimum condition for HS-SPME was 10 mL of
sample solution, extraction temperature of 50 oC, extraction time of 30 min and the addition of 0.05
mol/L sulfuric acid and 4.5 g of anhydrous sodium sulfate. Under the optimum condition, high accuracy
and precision of three organic acid preservatives in fruit juice were achieved.

Abstract
The recovery of waste engine oil was investigated in this study by thermal cracking reaction. The pyrolysis
process was designed as two-stage reactor including distillation process. The various factors affected to the
product yield and property were investigated, such as reactor configuration, nitrogen carrier gas flowrate
and reactor temperature. We found that the configuration as two-stage reactor increased the residence time
resulting in the improvement of final product properties: specific gravity and viscosity. The high yield of
pyrolysis oil was obtained from the single-stage configuration at high temperature but relatively low in
quality. Moreover, packed bed in the second reactor could enhance the color and properties of pyrolysis oil.

1. Background
Due to denaturation of protein drugs via oral administration, which is the most convenient mode of drug
delivery, protein drugs are usually administered by parenteral route. Another challenge in protein drug
delivery is to maintain the tertiary protein structure, which is essential to bioactivity. Exposure of protein
drugs to unfavorable conditions during formulation could reduce or even destroy their bioactivities. In
order to address all these concerns, one technique for oral delivery of protein drugs that can be used is by
employing protective coatings to control delivery. This may be carried out by the microencapsulation
process which isolates the core from its surrounding hostile environment. Most often than not, sodium
alginate-based hydrogels are well suited in microencapsulation applications because of its low cost and
stability when exposed to an acidic environment. As far as established methods are concerned,
encapsulation of proteins in alginate microparticles still suffers from certain limitations.
Therefore, this study’s major goal is to use external ionotropic gelation, a very convenient
microencapsulation method, in developing protein-loaded sodium alginate based microparticles and
evaluate its encapsulation efficiency and the model protein’s in vitro release behavior. Also, bovine serum
albumin (BSA) will be used as a model protein in this study.
2. Results
SEM images show that addition of model protein results to increase size and production of smoother
surface of micropaticles. Also, low moisture content was found for the fabricated microparticles of around
9.97%. with respect to swelling, acidic medium has caused minimal swelling while larger swelling ratios
were observed for pH 7.4 medium. Furthermore, encapsulation efficiency of BSA-loaded alginate
microparticles was recorded to be around 46.74%. Lastly, microparticle samples exhibited initial burst
effect after two hours of dissolution. Data also shows cumulative protein release of around 73.67% after
five hours of dissolution.

Abstract
In Taiwan, cultural & creative industry parks have become one of the developmental strategies of every
government's policy integrating cultural and economic development, and most of them adopt the method
of contracting-out management, that is, public-private-partnerships (PPPs). However, not every park can
create economic efficacy and achieve policy goals. This article focuses on the problems and controversies
of the outsourcing of Taiwan’s cultural creative industry parks with the theories of principal-and-agency
theory. Firstly, this article lists some problems of the cultural parks (five managed by the Cultural
Ministry and one by Taipei City Government) with the methods of literature review, depth interview and
case study & comparison. Secondly, this article further explains the types and reasons of these
controversies. Lastly, this article proposes some policy suggestions for these controversies, expecting to
make the governmental outsourcing more successful.

and Thailand as well. However, the revenues from mainstream tourism impacted to the social system
were dramatically changed, natural resources were largely exploited, and the economic profits were not
distributed fairly. Thus, The community-based management (CBT) became an alternative sustainable
solution. The qualitative was deployed as documentary research, the data collection was gathered from
the official report and previous research. Then, the CBT model and participation theory were employed
for analyzing. The research result founded that The community-based Tourism (CBT) improved a social
system in Thailand is along with the environment. This research suggests that the Thai government should
apply the CBT model and participation especially for a local community to nationwide.

Abstract
This paper discusses the epistemological challenges faced by social scientists in conducting qualitative
research on overseas Chinese family and consumption. It discusses the concepts, issues and subjectivity
challenges on constructing and narrating the Chinese realities in consumption research. It proposes an
institutional-actor approach to understand the concept of familism among the Chinese when investigating
their consumption behaviors. It argues that for the development of overseas Chinese reality, their
identities are largely shaped by socio-historical and socio-economic events. Particularly, the overseas
Chinese diaspora in the Southeast Asian region which has succeeded in becoming not only a formidable
economic force today, but also a unique form of capitalism in contemporary times. With such affluence
among the Chinese, however, there have been very few studies done on their capitalistic consumption
albeit any alterations to their existing value systems, and social institutions and ties. Several studies have
concluded that certain family systems not only survive in modern economic context but that they often
function positively to enable individuals to mobilize capital and other resources for production and
consumption.

Abstract
For the Mathieu equation, 2 2 0x a x b x cos( t ) we may divide the plane (a, b) into stable
and unstable zones called the stability chart. The stability chart is characterizing by the boundary curves
between the stable and unstable zones, indicate the values of (a, b) at which the equation shows periodic
response. The solutions of Mathieu equation in a stable zone are interesting as it is either periodic or
quasi-periodic. Linearity of the Mathieu equation makes the stability chart to be independent of the initial
conditions.
This paper show how we can examine the behavior of Mathieu equation in an stable zone to determine its
- -transition curves
will be examined as a sample stable zone. It will be shown that there are splitting curves within the stable
zone corresponding to periodic solutions. The boundary curves are associated to the point where the
Mathieu equation as stable behavior on one side and unstable on the other side. However, the new curves
are associated to the point at which the equation has periodic solutions and is stable on both ides.
Employing power spectral density, we discover the distribution of sub and super-harmonics as well as
quasi-periodic solutions of Mathieu equation. Energy-rate methods, time response, phase plane, Poincare
points, and power spectral density are utilized to examine the dynamic behavior of Mathieu equation at
different points within the stable zone.

1. Background
In tissue paper folding machines, the paper is transferred on the surface of folding drums by air suction,
Fig. 1. Small openings of air intake tubes are distributed on the folding drum surfaces. The air intake
tubes and air suction channels which run through the interior of the drum provide the pressure difference
between the opposite sides of the papers to form the suction force to attract the paper. At the downstream
of the folding drums, the paper sheets are released with air pressure discharge. Various multi-panel
interfolded overlap patterns can be achieved with different finger mechanisms, Fig.2. As the production
speed increases with wider paper webs, it was found out that the edges of sheet panels are misaligned as
they are stacked on the pack of folded sheets built at the downstream of folding drums. The disarranged
edges of the sheet packs cause unsatisfaction on the appearance quality and require engineering
investigation.
2. Results
Figure 4 shows the pressure transient responses of air intake tubes for the suction process for the first 3
seconds. Figure 5 shows the pressure transient responses of air intake tubes for the discharge process for
the subsequent 5 seconds. The required suction pressures to attract the tissue paper sheets attached to the
drum surfaces are calculated and plotted on the figures of the pressure transient responses to estimate the
response time for the folding drums to attract and discharge the paper sheets. It is found that the required
suction pressure of air intake tubes built up very fast for the attraction process. The delay for the attraction
of the paper sheets to the drum surface seems impossible, i.e., no slippage of the paper sheets on the
folding drums. However, the discharge process shows longer response times are required to release the
paper sheets, especially for the air intake tubes in the middle region of the folding drum. The difference
of the release time between the inner most and outermost air intake tubes can be up to 2 ms, for a folding
drum design of 3400mm span. The corresponding arc length of the folding drum to the 2ms response time
is about 5 mm, which agrees closely with the amount of edge misalignment on the pack of folded sheets.
Due to the fluid inertia, the pressures of the air intake tubes change slower near the middle region of the
folding drum than those in the outer regions, which are close to the vacuum pump. The air suction process
is a forced process caused by the vacuum pump. But the air discharge process is a passive process by
venting to the atmosphere. Also, the longer span of the folding drum design the larger the response time
difference between the air intake tubes in the middle region and outer region of the folding drum.

Abstract
Photovoltaic systems are becoming increasingly important and widely used in many applications, as they
are considered cleaner and renewable. Recently, there has been a technology research on the Internet of
Things (IoT) Smart Environment Monitoring and Real Time Systems (SEMAR) that can control and
analyze air quality parameters, perforated roads and congestion in a location in real time so that it can
help government in the massacre of road conditions. But now the development of this technology requires
an energy generation system that can be integrated easily and without burdening vehicles used to monitor
road conditions. To meet the needs of electrical energy is made independent power plant in the form of
photovoltaic system. The power plant is built using Maximum Power Point Tracking (MPPT) Modified
Perturbation and Observation (P&O) Technique to obtain a more efficient and effective system. In the
design, the size of solar photovoltaic is 18 V 50 Wp with a battery of 12 V 17 Ah, so to perform the
battery charging process required MPPT solar charger capacity of 5 A. With the use of MPPT MP&O,
obtained an increase of electric power from without MPPT, average of 9.67%.

Abstract
Major portion of the Lower Officers’ Hill colony situated in the city of Kohima, India, have been affected
including a 200 m section of Asian Highway-1 (AH-1), severely disrupting traffic and causing great
inconvenience for decades to the people of the Indian states of Nagaland and Manipur. The area is
composed of the Disang Group, made up primarily of shales intercalated with thin beds of sandstone and
siltstone that are highly jointed, fractured and weathered. A major stream called the Sitsie Rü flows in the
western boundary while two tributaries run parallel on the north and south. The area falls in a residential
zone that receives heavy rainfall during the Monsoon increasing the amount of water percolation into the
soil and toe erosion by the streams that pose great threat to the settlers. Geotechnical analyses of the slope
material and kinematic analysis of joint data is used to determine the existing slope strength and to assess
the potential failure mode. Study of satellite imageries are also undertaken to determine the local
structural influence of this unstable zone. The study aims to suggest some unique remedial measures for
this complex landside and thereby address this chronic problem that has tormented the people for several
years.

1. Introduction
There have been a number of major international fire accidents involving long vehicle tunnels. A fire
accident in the Mont Blanc tunnel connecting France with Italy happened on March 24, 1999. The tunnel
is 11.6 km long. The accident caused a large truck to catch fire and 39 people died. On October 24, 2001,
a large freight train caught fire in a 16.9 km long St. Gotthard tunnel between Italy and Switzerland. In
the accident, 11 people were killed and many people were injured.
There are many international studies to analyze the fire hazards of vehicle tunnels, but most of the
research objects are straight tunnels. The slope of the tunnel, the type of vehicle, and the flow of traffic
have a great influence on the development of tunnel fires. When formulating an emergency response
strategy for a tunnel, all parameters must be considered.
3. Results and discussion
After reviewing the weather data, the natural wind direction in summer and winter are in the opposite
direction. This paper analyzed the impact in the scene of the fire incident influenced by natural wind. The
famous international fire simulation software (FDS) was used to simulate the situation of three different
tunnel fire scenarios under the influence of seasonal winds.
In this study, the visibility of people and the temperature are used to discuss the environment which the
people in the tunnel are evacuated when a tunnel fire occurs. Three different cases were simulated to
analyze the influence of natural wind on Kaohsiung Cross-Harbor Tunnel. Cases were no natural wind,
winter wind (from January to March) and summer monsoon (from July to September). The results show
that the spread of smoke is greatly affected by the natural wind. The conclusions are not found in the past
research. The formulation of disaster response strategies must take into account the impact of natural
winds.

1. Research purposes
On the scene of a fire, smoke also does great harm to human in addition to the high temperature. The
anti-smoke tool has the characteristic of obstructing the view, which will affect people’s evacuation
activity. Some standards about full-scale hot smoke test have been published to analyze the smoke
controlling ability. The common test standards include 4391-1999 Smoke management systems - Hot
smoke test in Australia, JIS A4303 – 1994 Inspection Standard of Smoke Exhaust Equipment in Full-scale
Tests in Japan, GA/T 999-2012 Test method for verifying field performance of smoke management
system – Hot smoke test in China, and CNS 15937: Test method for field performance of smoke control
system − Hot smoke test in Taiwan. Although some test standards are issued internationally, the quantity
of the visual tracer particle injected has not been described in detail. Different fire loads have their
corresponding smoke generation amount. Some researches discuss the smoke generation amount. Some
empirical plume equations were developed at the California Institute of Technology (Cetegan, Zukoski,
and Kubota 1982), National Institute of Standards and Technology (McCaffrey 1983), and Factory
Mutual Research Corporation (Heskestad 1983, 1984). According to Handbook of smoke control
engineering, the smoke generation amount is shown in Equation (1a) and (1b) [20]: If there are too much
or insufficient smoke generated on the test site, it is possible to cause the distorted judgment result.
Therefore, it is a necessary topic to quantify the smoke generation rate of smoke generator during the hot
smoke test.
3. Results and discussion
There are some international standards for building smoke extraction system using full-scale hot smoke
test. For the judgment of validity, the flow direction of the smoke can only be visually observed. In this
study, smoke was released in a room to investigate the procedure for measuring the smoke generation rate.
This research applies some devices to do the test to define the procedure how to measure smoke exhaust
amount in a quantization way. In order to keep the smoke continuously floating during the experiment,
400c.c. of ethanol was burned in this study. The indoor temperature is moderately raised and the
buoyancy of the smoke can be maintained. Recording the thermocouple measurement temperature can
analyze the state of the room. The spread of hot smoke in the room can be observed through the four sets
of CCTV. From the results, it is proved that the concentration and distribution of smoke are immediately
and accurately identified by the decay rate of light and the recorded CCTV images.

Abstract
The occurrence of cavitation phenomenon is common in a fluid flow as the hydrostatic pressure of the
fluid reaches the vapour pressure at a given temperature. In recent years, cavitation phenomenon is widely
used as a constructive tool in engineering. Orifice plate design is crucial to generate hydrodynamic
cavitation and achieve the desired cavitating intensity for engineering applications. Hence, the main
objective of this paper is to establish a relation between cavitation intensity and orifice constriction ratio.
Therefore, two sets of orifice plates namely Single Hole Orifice (SHO) and Multiple Hole Orifice (MHO)
are designed and investigated. Cavitation intensity of all the orifice plates is quantified using cavitation
number. Finally, an empirical model is developed to establish the relationship between cavitation number
(σ) and orifice constriction ratio (𝛽).

Abstract
Technologies have the potential to change the way family businesses access and share information about
the owner’s way of life orientation. With the evolution of the Internet, WWW and social media, family
business owners face the dilemma of how to run their businesses their way while adopting technologies
that can help them run their businesses. This paper examines technology adoption and way of life by
gender of a rare panel dataset of U.S. family business owners who remained in business over 19 years.
Technology adoption was compared by Internet and social media use, and way of life of the owners was
examined by whether social media was used. Recommendations for future study are presented, as are
suggestions for how the study findings can guide and inform public policy and practices by business and
community development practitioners.

Abstract
Institution is defined as a society or an established organization for an educational, social, religious or
similar purpose that is working together for a common goal. Church is an example of religious
organization representing an institution. This study aims to assess the religious tourism and carrying
capacity of the National Shrine of Saint Padre Pio in Batangas. Data were gathered using survey and key
informant interview to determine the socio-demographic profile of the respondents and church structure,
rules regarding National Shrine of Saint Padre Pio. The study revealed that tourist-respondents in the area
are majority young adults in the age group of twenty to twenty five years old that have a monthly income
of ten thousand pesos and below. This is because in this stage of life, youth enjoy doing adventure and
activities like going to different places that have significant features in the country. Church, Healing,
Family bonding and Recreation are the common reasons of the visitors in visiting the area. Mode of
transportation is mostly by the use of private vehicles specifically cars and motorcycles. Carrying
capacity and total daily visit of the shrine is computed using the formula of Boullon and Limit of
Acceptable Change. The carrying capacity for Shrine was computed to be 1,720 and 431 for the upper
and lower limit respectively in the assumption that 8,000 square meters is being utilize while the carrying
capacity for 16,000 square meters is 3,442 and 861 for the lower and upper limit respectively. The total
daily visit the lower limit is 5,735 and 11,470 persons for 50% and 100% usage of the area respectively.
For the upper limit the standard total daily visit is 1,435 and 2,870 persons for 50% and 100% usage of
the area respectively. With the growing volume of visitors, environmental concerns like orderliness and
cleanliness may also be included in the set of rules when in the premises of the National Shrine of Saint
Padre Pio more specific for the solid waste management.

E-mail: [email protected]
Abstract
This research aims to study the concepts and types of priests of other religions which appear in the
Tipiṭaka, to study the Buddha's relationship with other religious priests and to use it as a practice for
Buddhists to live in harmony with other religions. The researcher used as a research method a
documentary and commentary of the Pali Tipiṭaka Siamese official version, Mahamakut Rajavidyalaya
and the Tipiṭaka and the Commentaries which are translations of the Mahamakut Rajavidyalaya
Foundation under Royal Patronage. The study mainly focused on the appearance of the Vinaya Tipiṭaka
and the Suttanta Piṭaka.
The result of this study found that other religions and priests, which appear in the Tipitaka as the 6
teachers' religions; Including Purnakassapa, Makhaligosala, Ajitakesakambala, Pakudhakaccayana,
Niganthanāṭaputra and Sañjayvelaṭṭhaputra. Each religion has a different viewpoint. Other religious
priests include Paribajaka, Tāpasa, Jatila, Añyatithika and Hermits. The relationship in terms of being an
adversary include Brahmins, Huhukajāti, Dīghanakhaparibājaka and Saccaka-Nigantha and so on. Then,
there is also a friendly relationship, such as Sīhasenapati, a disciple of Nigantha, Kūṭaḍanta-brahmana,
Mahasakuludayiparibajaka, Paribbajaka named Kandaraka and Dῑghatapassῑ- Nigantha.
When analyzing why other religious priests changed Buddhism. Due to the use of the miraculous miracle,
and from the curiosity or intolerance in the study of that person. In the past, the contact of the Buddha
with other religion's priests was friendly. If there was something to criticize, when he clarified, it was
considered terminated. If there is some good, it was accepted and applied in Buddhism. If the act of the
Buddha was to deal with other religion's priests as a practice for the disciples of today, it is possible to do
so.

1. Background
In this study, we point out that Managing system and method of fishing gear using automatic
identification device. An automatic identification device installed in a fishing gear such as a fishing net,
fish trap fish trap provides the fishing gear information including the identification information and the
position information by wireless communication, it is received, classified, managed and stored by the
receive station. Using this information we can judge the status of fishing gear and systematically manage
it.
2. Methods
The automatic identification device installed in the fishing gear transmits the information of the fishing
gear(identification information, location information) regularly. This information is transmitted to the
control server of the land authority and registered in the database server.
The fishing gear management system can check the status and location of the fishing gear in real time and
analyzes the stored DB to determine and manage the state of the fishing gear. If an abnormal condition
occurs in the fishing gear, It transmits real-time abnormal condition to the control ship and it can perform
management (finding and tracking a lost fishing gear) of fishing gear.
3. Results
Recently, the maritime environment contaminated by the abandoned fishing gears. To solve this problem,
there are required systematic management techniques for the fishing gears based on ICT technologies.
The existed management system of fishing gears are optionally use by owners, but there needed a
monitoring and control architecture of integrated and national surveillance. To do this, we introduce the
architecture for effectiveness monitoring and management which collects position and state information
by automatic identification buoy device to send the fishing ship, administrator ship, and shore side control
center based on IoT and mobile network. Especially, we develop the ENC-based integrated control system
for efficiency management which provides position indication, state information display and loss alarm of
fishing gears.

1. Background
Visually impaired people face more difficulties in daily life than sighted people. For example, they may
encounter difficulties in finding an object at home or picking up an object that falls down on the ground.
When they go out, they may meet with accidents because of the barriers on the roads to their destinations.
2. Results
The assistive technology system can provide short-term but real-time remote visual assistance. It can
effectively help the visually impaired people to eliminate the problems encountered at that time. The
assistive technology system has an accessible user interface. The visually impaired people can operate the
system on their own without the help from anyone else. The assistive technology system is an embedded
system which equips with information sensors and can be self-propelled. It can move ahead, back and
make a turn. It has the function of barrier detection which can automatically stop the system from moving
ahead when there is a barrier ahead. The system features the function of image capture and can transmit
images of the surrounding environment to remote vision-assistive provider when needed. The image
capture device in the assistive technology system supports left and right steering. In addition, the assistive
technology system supports two-way audio transmission, and thus the visually impaired people and
vision-assistive providers can communicate directly with each other. The vision-assistive providers can
remotely control the system and provide guidance according to the environment and conditions faced by
the visually impaired. The remote control can be operated by using a computer or a mobile phone.
Visually impaired people can use the developed assistive technology system at home or during movement.
In the future, the function of the sensing environmental information such as object color, environmental
brightness, luminance and temperature, and position of heat source and barriers will be extended. It is
hoped that the assistive technology system can be used by the visually impaired people for the purpose of
home safety.

1. Background
In this paper, we propose a method to efficiently acquire 3D image data using multiple Intel realsense
d435 cameras and ChArUco boards. The Intel RealSense Depth Camera D435 (Keselman, et al., 2017) is
an USB-powered camera that includes wider field of view depth sensors and a RGB sensor. ChArUco
board is a mixture of Chessboard and Aruco pattern. The advantage of this board is that each corner is
given an id so that it can be calibrated more accurately. In this paper, we calculate the affine matrix
between each camera and ChArUco board, and calculate the affine matrix which is transformed from each
camera to the reference camera coordinate system based on the acquired affine matrix. For more accurate
calibration, we define the cost function and optimize the parameters through function optimization with
the gradient descent method.
2. Results
Table 1 shows the results of this paper. In this paper, we reduced the average error from about 45mm to
5mm through 10 million iterations. The method proposed in this paper can efficiently remove errors that
occur in multiple RGBD camera calibration.

Abstract
In this paper, a mult-mode modulation transceiver for 3G and 4G wireless communication system is
proposed. Due to the fact that different wireless communication systems were developed in the recent
years, how to integrate different transceivers in one hardware is an important issue. This paper proposes a
multi-mode modulation scheme based on soft defined radio to integrate different modulation schemes
including quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation(16 QAM) by
tuning the parameters. First, we verify signal simulation by Matlab, then we use VHDL of Alter Quartus
II softwave for timing simulation, pin planner and circuit design. Finally, download the software into the
Altera EP2C35F672C6N IC, and verify simulation with result by Logic Analyzer.

Abstract
The main purpose of this paper is to integrate the position sensorless control and Takagi-Sugeno (T-S)
speed control of permanent-magnet synchronous motor (PMSM). In the aspect of position sensorless
control, the extended electromotive force (EMF) algorithm is adopted and the extended EMF is estimated
by using a least-order observer. In the aspect of driving control, the T-S fuzzy models are implemented to
design the controller based on the concept of parallel distribution compensation (PDC). The stability
analysis is verified through Lyapunov theorem. Finally, the controller gains are obtained by Linear Matrix
Inequality (LMI). In this paper, dynamic model and system configuration are first introduced. Next, the
principle of extended EMF method is demonstrated. Moreover, the controller is designed based on T-S
fuzzy models and system stability is analyzed. All control schemes are digitally realized by the
microcontroller. Finally, the rotor position estimation and speed tracking performance are validated by
experimental results.

1. Background
The demand for image-based intelligent security system is steadily increasing, and the development of
deep learning is accelerating [1]. In order to improve the monitoring performance, an algorithm that
requires a large amount of calculation based on high resolution image information is required, but this
increases the cost of the security system. Therefore, it is possible to construct an economical system by
summarizing and transmitting high-resolution image information as much as possible [2, 3]. In this study,
a pedestrian detector and a tracer are used to express the behavior patterns of pedestrians in a shortened
way, and a method of effectively classifying normal and abnormal is presented.
2. Results
In order to judge the situation, it is assumed that 1 ~ 10 people are supposed to invade the group, and it is
assumed that there is unconventional movement, speed, directional movement, The abnormal situation
DB is constructed assuming that the delayed scene is abnormal. Lobby pedestrians are represented by
compressing the images in 48x14x3 pixels of density, speed and direction and classified them into normal
and abnormal by using CNN-LSTM deep learning network. We studied each 48x14x3 image using CNN
network and learned the temporal classification by connecting the fully connected layer sequence of CNN
network to the input of LSTM network.
We divided the entire DB into 50% training DB and 50% test DB, and performed learning by changing
the number of fully connected layer output nodes (N) and the number of hidden nodes (M) in LSTM.
Table 1 shows the results of the recall according to the parameter change. The relatively simple
CNN-LSTM structure shows that this performance is due to the efficient compression of the pedestrian
surveillance image to 48x14x3 level.

Department of Electronic Engineering, National Kaohsiung University of Science and Technology, First
Campus, Taiwan, ROC
E-mail: [email protected]
1. Background
Due to the benefits of low loss, high power-handling capability, and high selectivity, waveguide bandpass
filters (BPFs) have been widely used in wireless communication, radar, and satellite systems. Various
types of waveguide BPFs have been developed and extensively studied recently. However, most
investigations of the waveguide BPF designs adopted the “waveguide ports”, that is, uniformly extended
waveguides, to be the input and output ports of the filter (see an example shown in Fig. 1(a)). In many
practical applications, however, filters are connected to external systems and/or circuits using coaxial
cables. In such a scenario, a coaxial-to-waveguide adaptor would be required in the connection between
the filter with waveguide ports and external circuits. The additional coaxial-to-waveguide adaptors would
not only increase the cost of circuit integration, it could also influence the filter performances. Therefore,
the design of a waveguide BPF with coaxial feedings has become an important research in the modern
microwave engineering.
2. Results
To demonstrate the proposed design, a 6-pole BPF having Chebyshev response is developed in this work.
The center frequency f0, bandwidth BW, and passband return loss level of the filter are 5.8 GHz, 0.1 GHz
and 20 dB, respectively. Meanwhile, the standard WR-159 rectangular waveguide is utilized to construct
the filter. Fig. 2 shows the simulated and measured frequency responses of the filter. As can be seen, the
performances of the designed filter, including the bandwidth, in-band insertion loss (|S21|), and required
return loss (|S11|) level, are very close to the desired design. The in-band insertion loss is measured to be
around 0.58 dB, which is about 0.27 dB higher than the simulated result. The frequency shift between the
measured and simulated passbands is about 7.5 MHz. Also, only the return loss near the upper edge of the
passband is slightly higher than the expectation. The small discrepancies should be attributed to the
material losses and the variation in manufacture. These satisfied filter performances demonstrate the
validity of the proposed design method.

1. Background
In the field of surveillance cameras, People Counting is a technology that has long been developed for the
purpose of floating population analysis. However, due to the limitation of hardware specification of
embedded board, high performance algorithm could not be installed in camera. Launched in 2017, the
NVIDIA Jetson TX2 is a high-performance embedded board with a GPU. The proposed method proposes
a real time people counting using Jetson TX2 and a stereo camera.
2. Results
To evaluate the performance of the proposed method, 23 videos were taken every 5 minutes and the
counting accuracy was measured. Table 1 shows the comparative evaluation of the proposed method and

1. Background
Recently, there are many researches which adopts 4th industrial revolution element technologies (AI,
big-data, IoT, etc.) into maritime domain such as ship, shipyard and service (3S) fields. Especially,
intelligent analysis techniques apply to support maintenance for machinery equipment of ship as a service.
To do this, we need enough data to extract a meaningful analysis result from machinery facilities.
However, there are no standard for data exchange and management of machinery and automation
equipment in vessel.
To solve this problem, the standardization works of ISO 19847 and 19848 are in progress by TC 8. In the
these standards, the first one defines requirements of shipboard data servers to share filed data at sea, and
the other one covers requirements of standard data for shipboard machinery and equipment. The ISO
19847 presented shipboard data server as shown in Fig. 1 (a), and we configured a system architecture
based on the shipboard data server standard which as shown in Fig. 1 (b). In this paper, we implement the
shipboard data server based on the ISO 19847, and develop a fault prediction system using the
machine-learning (ML) method to provide maintenance supporting service for engine room (main engines,
generators, etc.) as one of the application. When the application exchanges data with server, it should
follow the IEC 61162-450 (streaming data), XML/JSON (formatted data) and/or CSV (file data) by the
ISO 19848.
2. Results
Currently, we finished ML for the developed system using the migrated AMS data. However, the data
only contains normal state values. Therefore, we going to research and develop a generation module for
simulation fault cases to adopt mutation of the genetic algorithm (GA). We will conduct the reinforcement
learning for the system, and connect with real-time data hereafter.

Abstract
Magnetic components, such as inductors, common mode inductors and transformers, are important
components of power converters. Their placement and wiring may affect the ability to suppress
electromagnetic interference noise. Due to the miniaturization and increasingly higher power density, the
composition of the power converters become more and more compact, which leads to the near field
coupling effects among the components. Our study analyzed the mechanism of the near-field magnetic
coupling among the magnetic components, and further verified the accuracy of the near-field magnetic
coupling parameters obtained by the simulation through experiments.

1. Background
Recently, many studies are actively in progress to apply the big-data analysis techniques of various fields.
In the sea navigation domain, the maritime big-data is defined as gathered data from the navigation and
communication equipment of ships such as AIS (automatic identification system). In addition, importance
of the maritime safety is emphasizing, because maritime accidents are rising with increasing of maritime
traffic. To reduce the accident risk, we proposed a safety information providing system to prevent the
collision accident by towing lines in this paper. The purpose of towing lines is to drag something on water
such as fishing nets and accident (shipwrecked, etc.) vessels by towing ships. However, the towing lines
are very difficult to distinguish in sea area when bad visibility condition or nighttime, especially for high
speed and small size ships. The system analyzes the degrees of risk to use a proposed algorithm based on
vessel traffic monitoring system, and provides the safety information service to the potential (high-risk)
ship by automatic VHF voice communication using the TTS (text-to-speech) module. The concept of the
system architecture is as shown in Fig. 1.
2. Results
We developed the vessel monitoring system based on ENC (electronic navigational chart) for VTS (vessel
traffic service) center, and implemented TTS module and digital to VHF voice converter. Also, we made
the DCPA and TCPA calculation modules, and we are optimizing the automatic tracking algorithm to find
the towing ships with fishing nets or accident vessels, and so on. In near future, we will accomplish the
integration the developed modules into the vessel monitoring system, and conduct enough testing.

propose an optical reader that can measure the transmittance in a very sensitive and rapid manner on a
hybrid paper-polymer centrifugal disc platform. This device enables real-time monitoring of multiple
samples by measuring the absorbance of the light transmitted through the paper integrated on the disc
between the light emitting diode (LED) and the photodiode (PD) regardless of the ambient light condition.
To confirm its efficiency, we analysed one of the blood's important indicators, glucose in a successful
manner within 10 seconds without any additional complex image analysis. In addition, we discussed the
results by comparing with the reflectance-based methods and with those of the previously reported studies
by introducing a figure of merit to evaluate the performance of the assay.

Abstract
Calcium carbonate (CaCO3) reinforced poly(butylene succinate) (PBS) composites have been produced
with different CaCO3 concentrations by using a twin screw extruder and an injection molding machines.
The mechanical, thermal and morphological properties as well as raw materials cost estimation have been
investigated. Experimental results indicated that the tensile and flexural strengths of the PBS matrix resin
were improved with increasing the CaCO3 contents from 10-30wt%. However, they were dropped at
50wt% due to the agglomerations of CaCO3. The heat distortion temperature (HDT) was higher than
those of the neat PBS resin by around 10°C. Scanning electron microscopy (SEM) indicated some
agglomerations at high CaCO3 contents. CaCO3 acted as nucleating agent only at 10wt%. Higher than this
content, it acted as filler and its agglomerations reduce the degree of crystallinity by around 5%.
Maximum reduction of raw materials cost by around 48% was observed at 50wt% CaCO3.

Abstract
To enhance the extraction efficiency of carotenoids from yellow pulp of Gac fruit, the use of Accellerase
1500, a commercial cellulase, with various concentrations (0.25-3%, w/w) was applied. The results
showed that the application of Accellerase could promote the extraction of carotenoids from yellow pulp
as evidenced by the lutein, lycopene and β-carotene tended to increase with increasing the levels of
Accellerase used. The suitable concentration of Accellerase was approximately 0.5% as indicated by the
highest contents of lutein and β-carotene were found while the lycopene content was still quite high.
According to the results, the utilization of cellulase treatment could be applied for increasing yield of
carotenoid extraction from carotenoid-rich plant, especially yellow pulp from Gac fruit.

1. Background
Paragonimus are commonly known as lung flukes that belongs to family Paragonomidae of order
Plagiorchiida (Toledo and Fried, 2014). Those trematodes are the main parasites for paragonimiasis in
lung of many mammal species and human (Sugiyama et., 2004). Those flukes reveal a large range of
prevalence in tropical and subtropical regions, especially in Africa, Asia, and South America (Peters and
Pasvol, 2007). In freshwater aquatics, crabs, snails and some shrimp have been known an important
zoonosis as intermediate host. Moreover, metacercarial lung flukes were found in crayfish that infected to
lung tissues of the crayfish-eating raccoon (Diaz, 2011). In Thailand, there are common 3 species of
Paragonimus such as P. westermani, P. siamensis, P. heterotremus that are the important case of
pulmonary, abdominal and cerebral paragonimiasis (Vajrasthira, 1986). Recently, in Thailand, crayfish
become the famous exotic pet and aquaculture for those decapod farms. However, crayfish (Cherax sp.)
were found in natural environments (Wanjit and Chaichana, 2013). Soh et al. (1966) also reported that
shrimp as intermediate host of paragonimus westermani in korea. Therefore, the aims of this study were
development of molecular genetic detection of lung fluke infection in crayfish (Procambarus and Cherax)
by using multiplex real time PCR analysis.
2. Results
All primers showed the specific bands of DNA-binding dye and the lengths in each PCR of individual
products. However, some band intensity for ITS2 primers were weak. Then, in real time PCR analysis,
paired primers of CO1 were used for detecting the Paragonimus in our experiments. Moreover, there was
undetectable for distilled water and genomics of nematode as negative controls. For a multiplex real time
PCR, three primer sets showed clearly signal detections for separating the genomic DNA of positive
controls in each sample of 3 metacercarial flukes. For detection limit, a minimal amount of DNA was 0.1
ng/ml. In 41 freshwater crabs collected from natural environments, the sensitivity, specificity and
accuracy of real time PCR analysis were 81.5, 90.0 and 85.0 %, respectively in comparison with light
microscopy independently. In experiments of crayfish, no signals of 16 samples were found in chemical
treatments with bithionol from 20 samples. Three samples from hepatopancreas were detected as P.
heterotremus, and 1 sample as P. westermani. No signal detection was found in P. siamensis. However,
parasites were not observed under light microscope analysis for any sample. In experimental groups with
fed on crab tissues, 11samples from hepatopancreas were detected as P. heterotremus for 7 samples, and
as P. westermani for 4 samples form 20 samples. Nine samples were not detectable. In light microscopic
observations, the results were congruent with molecular detections for P. heterotremus for 6 samples and
P. westermani for 2 samples. In contrast, 2 samples were examined as P. heterotremus under a light
microscope, but not in real time PCR. Eight samples in light microscopic results were agreed with in PCR
that there were not found any positive result for both methods. However, 2 samples were detectable in
PCR but not in light microscope.

1. Background
Nano dimensions provide substances with a number of specific properties applicable in different areas of
human activity. Silver and gold nanoparticles have considerable potential for medical applications. At
present, nanoparticles are predominantly produced by physicochemical procedures that are often not
environmentally friendly and green nanotechnology is therefore a desirable alternative (Pereira L. et al.,
2015; Huang J. L. et al., 2015. Extensive and long-term knowledge in the field of microbial cultivations,
ease process scale up and the enormous range of enzyme activities of microorganisms predict their use in
this field. In the paper, we summarize our knowledge of nanoparticle production using different types of
bacteria and the basic characteristics of the obtained nanoparticles.
2. Results
The screening of the 12 strains of bacteria proved that extracellular enzymes of all strains were able to
synthesize silver and gold particles from AgNO3 or HAuCl4 in varying amounts. The largest amount of
nanoparticles was observed after 72 hours of incubation in the supernatant at a 10 mM concentration of
AgNO3 or HAuCl4. The detected absorption maxima for semiquantitative spectrophotometric
determination of the presence nanoparticles has to be determined individually depending on the size of
nanoparticles produced by different strains. Pseudomonas fluorescens CCM 2115 and Pseudomonas
aeruginosa DBM 3777 showed the highest ability to synthesize silver and gold nanoparticles.
Synthesized nanoparticles showed a very narrow distribution of sizes and shapes, which is important for
practical use. Most often, they were almost spherical polygons. P. aeruginosa generate relatively large
polygons silver nanoparticles with dimensions of 50-90 nm. In contrast, B. subtilis synthesized silver
polygons of about 10 nm in size, and P. fluorescence formed fibrous shapes with a diameter of about 10
nm. P. aeruginosa and E. coli synthesized polygonal nanoparticles of gold up to 15 nm in size with a
deviation of approximately ±3 nm.

* E-mail: [email protected]
1. Background
Rhamnolipids are biosurfactants with many potential industrial applications due to their unique properties
- biodegradability, physico-chemical stability and low toxicity. Although rhamnolipids were studied for
more than 60 years, industrial production allowing their commercial use is still not satisfactorily solved.
The big problem is still the high price and purity of the products obtained. A possible solution is to
increase the productivity of production strains and improve downstream processes which make up a
significant part of the total production cost (Abdel-Magoud et al., 2011; Randhawa and Rahman., 2014;
Chong, 2017). The aim of our research was to optimize the batch cultivation in a laboratory bioreactor
with the purpose to enhance the rhamnolipid production.
2. Results
Glycerol, used as the sole carbon source, provided very good yields of rhamnolipids for the given strain
and as a hydrophilic substrate, allowed easy isolation of rhamnolipids from the cultivation media.
Although limitation of nutrients in the medium is usually a significant factor in the production of
rhamnolipid-type metabolites, we have not find an increase in production even when the phosphorus
content is reduced to 10% of the concentration used in the standard medium. On the other hand, a 20%
reduction in total nutrient concentration in the medium resulted in a 26% increase in rhamnolipid
production in the bioreactor. However, this finding can also have a considerable economic effect,
especially in larger cultivation volumes. Another effective mechanism for increasing the production of
rhamnolipids was modification of the cultivation temperature. During cultivation of P. aeruginosa DBM
3774 at 37 °C, the production of rhamnolipids doubled compared to cultivation at 30 °C. P. aeruginosa
DBM 3774 shown considerable variability in the production of rhamnolipids depending on pH. This
strain achieves the highest production of rhamnolipids at pH in the range of 6.7 to 7.1, which is a little
higher in comparison to other producers. After optimization of all tested parameters achieved
concentration of rhamnose in the medium was 5.7 g / l, which corresponds to a concentration
rhamnolipids 14.0 g / l.

Glucose oxidase (GOx) composites with conducting polymers (e.g., polypyrrole (Ppy)) are excellent
nanobiomaterials suitable for the design of bioelectronics devices such as biosensors and biofuel cells.
Immobilization of GOx is a very important issue affecting the enzymatic activity, biodegradability,
longevity and stability, which is one the most important and challenging characteristics in practical
application of biosensors. The purpose of this research was to evaluate impact of polypyrrole (Ppy)
composites on stability of GOx enzyme.
Spectroscopic properties of GOx, flavin adenine dinucleotide (FAD) and composites of these compounds
with polypyrrole (Ppy) were investigated in a sodium acetate buffer solution. In the present study, the
nanosecond fluorescence quenching was observed for GOx/Ppy and FAD/Ppy composites by the
steady-state absorption and time-resolved fluorescence spectroscopy technique.
The exploration of native GOx and FAD solutions confirmed that about 5% of FAD dissociated from
GOx during the period of solution preparation, and this fraction remained constant for 1 month. It has
been found that the Ppy, which formed composites with FAD and GOx, facilitated the removal of FAD
molecules from GOx and twice reduced the fluorescence decay rate. Differences in the FAD and Ppy
average fluorescence relaxation times showed that the FAD composite with Ppy and Ppy effectively
quenched the FAD fluorescence and FAD could not freely unfold. The intramolecular electron transfer
took place between adenine and isoalloxazine moieties over the first 5 ps after the excitation. The findings
are very useful in the selection and adaptation of enzyme immobilization strategies, which are applied in
the development of biosensors and biofuel cells.

E-mail: [email protected]
The human genome encodes four Piwi members, including Hiwi, Hili, Hiwi2 and Piwil3. Piwi is the germ
line-specific subclass of Argonaute proteins. The PIWI proteins family members have been demonstrated
to have essential roles in spermatogenesis in mice. Piwi gene null mice demonstrate loss of germ cell
phenotype and these phenotypes may be linked to high expression of retrotransposons. In this study, we
would like to investigate the expression of Piwi in human spermtogenesis by collection of discarded
azoospermia testes tissue from patient after IVF (in vitro fertilization) treatment.
Azoospermia is the medical condition of a male not having any sperm in their semen. It is associated with
very low levels of fertility, and azoospermia cases are idiopathic, since the molecular mechanisms
underlying the defects remain unknown. Azoospermia has two forms: obstructive azoospermia (OA),
where sperm are created, but cannot be mixed with the rest of the ejaculatory fluid due to a physical
obstruction, and non-obstructive azoospermia (NOA), where there is a problem with spermatogenesis,
this failure may occur at any stage in sperm production for a number of reasons. This situation may be
caused by genetic abnormalities.
We analyzed the mRNA expression level of Piwi in the NOA testis compare with OA testis by real time
PCR. Testes tissue from NOA group expressed significantly (P < 0.0001) lower Piwi levels than those
from OA group. Based on these data, we suggest that Piwi genes may involves spermatogenesis in human
testis.

1. Background
Balance is required for maintaining static or dynamic posture, performance of ADLs and moving around
safely in the community [1]. As balance is affected by the progressive loss of sensorimotor functioning
with increasing age [2]. Many researchers have suggested an evaluation method of balance for static state
[3,4,5], but these measures are difficult to relate to activity requiring dynamic balance. The aim of this
study was to develop a robust evaluation algorithm of dynamic balance using an inertial sensor and a
computational geometry technique known as a convex hull algorithm.
2. Results and Discussion
Table. 1 shows the average age and the postural stability score. There was a significant difference for the
postural stability score between the groups (p=0.011). The high score group have significantly less lower
balance function than low score group. Fig. 2 shows representative convex hull for five different ADLs
(a-e) of low and high score groups. Each pair (nx, ny) of represents a point in the xy-plane. This
difference showed a possibility that the developed stability index based on the convex hull algorithm
would be applied to an evaluation of balance.

E-mail: [email protected]
Despite substantial progress in the study of cancers, important questions remain about the elucidation of
the relationship between the molecular origins of cancers and their resulting phenotypes. Network biology
is an integrative and systems-level approach for the interpretation of genome data, provides insightful
models for genetic phenomena, and sheds light on disease mechanisms via the identification of modules
perturbed in disorders. Deciphering the function of cancer-associated genetic variants is likely to get us
closer to achieving an understanding of cancer architecture that will ultimately be translatable into clinical
applications.
Cancers have been the first cause of death in Taiwan for 36 years. The number of deaths exceeded 48,000,
accounting for 28% of all Taiwanese deaths in 2017. Currently emerging big data techniques are
transforming medical science into a data science. Nation-wide collections of physician and hospital
claims data allow exploring the health state of an entire country’s population. Our studies integrated
systems-level molecular and genetic basis as well as population-based electronic health records (EHRs) in
Taiwan to discover cancer comorbidities.
In this work we constructed a cancer comorbidity network by EHR data and analyzed the structure of
comorbidity disease network stratified by gender and age. We also constructed a molecular disease
network and a protein-protein interaction network by public biobank datasets. Networks serve as a
paradigm for data integration and analysis, providing a systems-level understanding of the mechanisms
underlying diseases. With use of a variety of datasets, we inferred disease pathway and analyzed the
disease trajectory to understand the mechanisms in cancers. Understanding of the dynamics of
molecular-based network and population-based network may be helpful to elucidate potential biomarkers
of cancer progression and translate this knowledge about cancer pathogenesis for the development of
better strategies for the prevention, diagnosis, treatment and prognosis.

In order to increase the swine and poultry production, it’s commonly to raise animals in areas of
high-density population. Therefore, the infectious disease could spread easily and rapidly. Among the
infectious disease, viral diseases play a great role in yield reduction. This study was conducted to develop
antivirus agents based on probiotic Bacillus strains. For the purpose of screening of bacterial strains with
antiviral activity, 106 bacterial strains were isolated from the soil samples that obtained from the
Experimental Farm of National Taiwan University by using enrichment culture technique. The
cytotoxicity of these bacterial isolates toward baby hamster kidney (BHK) cells were determined. In
addition, the antiviral activities of these bacterial isolates were evaluated by using the Sindbis virus
screening approach, in which the inhibitory effects of these bacterial isolates against Sindbis virus (SBV)
replication in BHK cells were determined. Among these bacterial isolates, three strains (AC, CK, and LN)
showed low cytotoxicity and high antiviral activity and were further identified according to their
morphological and biochemical characteristics. The bacterial cultures of AC, CK, and LN were separated
into the extracellular supernatant, intracellular extract, cell wall fraction, and whole-cell culture, which
were determined their cytotoxicity toward BHK cells and human colon epithelial Caco-2 cells, and their
inhibitory effect against SBV replication in BHK and Caco-2 cells. In the BHK cell model, the
intracellular extract of CK showed no cytotoxicity but exhibited anti-SBV activity. In the Caco-2 cell
model, the extracellular supernatant, intracellular extract, and whole-cell culture of CK showed no
cytotoxicity but exhibited anti-SBV activities. The mRNA expression levels of antiviral factors, including
IFN-β, IL-6, MX1, and ISG56, of the virus-infected Caco-2 cells were further determined. The results
indicated that extracellular supernatant and whole-cell culture of CK significantly increased the IL-6
expression levels, intracellular extract of CK significantly increased the ISG56 expression levels, and
whole-cell culture of CK significantly increased the MX1 expression levels in the SBV-infected Caco-2
cells. Therefore, the inhibitory effect of CK against SBV replication in Caco-2 cells could be attributable
to the fact that CK could enhance the expression of cell-intrinsic antiviral factors. These results suggested
that CK might have a potential to be developed as feed additives with antiviral activity.

Evaluation of Cysteic Acid in Bleached Hair Using Soft X-ray Spectroscopy

Development Headquarters, Milbon Co. Ltd., Japan
E-mail: [email protected]
Abstract
Bleaching is one of hair-decoloring techniques widely used in the beauty treatment. Since hydrogen
peroxide is used in this process, disulfide bonds in proteins are oxidatively cleaved and cysteine residues
are converted to cysteic acid residues. Increased cysteic acid is considered to be a major cause of hair
damages. Infrared (IR) spectroscopic measurement has been a mainstream up to now for evaluation of
cysteic acid. However, since the spectral peak derived from cysteic acid detected by IR spectroscopy is
small, so it is difficult to argue the generation behavior further in detail. In this study, by analyzing the
chemical structural state of hair sulfur atom by X-ray absorption fine structure (XAFS) measurement
using synchrotron radiation X-ray microbeam, we have discussed the generation behavior of cysteic acid
within hair cortex compared with IR spectroscopic method. It has been found out that cysteic acid
generation in hair cortex is diffusion-controlled because the amount of cysteic acid obtained by both IR
spectroscopic method and XAFS measurement increases linearly with square root of bleaching time. This
result of XAFS measurement strongly supports the proposed diffusion model that the diffusion-controlled
behavior for cysteic acid generation in the cortex is caused by controlling the diffusion of hydrogen
peroxide from cell membrane complex into cortical cell. In addition, the deviation from this linearity has
been observed in the long-time bleaching samples from a result of XAFS measurement, and it has been
suggested that the reduction of cysteic acid due to the protein outflow from hair is additively detected.
From this result, it is considered that XAFS measurement has higher sensitivity than IR spectroscopic
measurement in evaluation of cysteic acid in hair cortex.

1. Background
Pestalotiopsis microspora NK17 is an entophyte that is capable of producing amount of secondary
metabolites, such as taxol, one of the widely prescribed anticancer drug. Analyzing the metabolic
profiling may be helpful to improve the production of Taxol.
2. Methods
High performance liquid chromatography (HPLC) was used to detect the fermentation products and then
purified by semi-preparative HPLC. The structure of these compounds were elucidated by NMR
(containing 1H-NMR,
13C-NMR, HSQC and HMBC). To explore the biosynthesis of them, metabolites in
the strains carrying individual deletion of the 36 PKS genes in NK17 were analyzed by HPLC.
3. Conclusion
Four more dibenzodioxocinone derivatives in the liquid culture of the isolate NK17, i.e. pestalotiollide C
(2), 1’,2’-dehydropenicillide (3), 3’-methoxy-1’2’-dehydropenicillide (4), and a new metabolic product,
1’,2’-epoxy-3’,4’-didehydropenicillide (5) were defined. Interestingly, all the four compounds share the
same carbon skeleton of pestalotiollide B (1), a characterized dibenzodioxocinone derivative. Results
showed that deletion of pks23, pks37 and pks45 led to a significant decrease of compound 1 and 3, while
deletion of pks24, pks34 and pks39 led to a significant decrease of compound 2 and 4. Deletion of pks28
and pks1 could reduce the production of compound 1 and 4, respectively. The addition of side chains of
the compounds were deduced. The data may help to illustrate the biosynthesis of dibenzodioxocinones
and help to create new CEPT-inhibitors in fungi.

Abstract
The effects of temperature on the decolorization kinetics of methylene blue for photo-fenton using
Fe-diatomite were studied at 25, 55 and 75C. The chemical compositions of Fe-diatomite were analyzed
by X-ray fluorescence. The surface area, pore volume and average pore diameter were determined by
BET method. The photo-fenton process follows pseudo first-order reaction in the first stage. The linear
relationship between ln C/C0 and reaction time (t) was obtained. It was seen from the result that the
decolorization rate constants (k) decreased with the increasing temperatures because of the accelerated
decomposition of H2O2 into water and oxygen. The reaction activation energy (Ea) was -2.97 kJ/mole.

1. Background
Biomass energy, or bio-energy, refers to renewable energy by converting biomass, and is the most
available resource on Earth, as it is a value energy product that can replace depleting fossil energy.
Biomass mainly consists of cellulose, hemicelluloses, and lignin, with cellulose content about 40~50%,
hemicelluloses content about 2~30%, and lignin about 5~20 %. After conversion, biomass can be
prepared into liquid, gas, and solid fuels. For the increasingly scarce fossil fuels, biomass energy is an
important resource. Another purpose of this study is to develop a computer simulation model for the
bubbling fluidized bed biomass gasification process that can accurately forecast the various operational
conditions of the gasification furnace. The development of the original model uses the ASPEN
PLUS-based Gibbs free energy minimization.
2. Methods
According to the gasification process, when using ASPEN PLUS to establish the model for a bubbling
fluidized bed biomass gasification furnace, the DRY-REAC (using the reactor RSTOIC model) and
DRY-FLSH models are combined to simulate the drying process. The DECOMP model uses the RYield
reactor model to simulate the pyrolysis process of biomass decomposition (non-conventional components
are broken into elements and ash). The GASIFIER model uses the RGibbs reactor model to simulate the
gasification process, the RGibbs reactor model uses Gibbs free energy minimization, and the SEPRATOR
model uses the SSplit Fractions model to separate syngas and ash. The ASPEN PLUS-based bubbling
fluidized bed biomass gasification furnace model
3. Results
The simulation results found that CO2 content decreased with rising gasification temperature; however,
the H2 and CO contents increased, while the CH4 content changed little. In addition, with the rising ER
value, the CO, H2, and CH4 contents decreased while the CO2 content increased. The results are consistent
with Narváez et al. (1996), who used pine sawdust in a bubbling fluidized bed for gasification. Simulation
results proved that the ASPEN PLUS-based bubbling fluidized bed biomass gasification model can
accurately simulate the bubbling fluidized bed’s biomass gasification process with relatively better
reliability and applicability.

1. Background
Mercury is a highly toxic pollutant. Inorganic mercury can be converted into methyl mercury, and easily
accumulates in living organisms by contaminated drinking water, food chain and soil. An optical chemical
sensor (optode) is a device that is interesting in determination of mercury because of fast, low cost, and
simple monitoring. Moreover, the detection by optodes allows visualization of color changes by the naked
eye, which makes them suitable for on-site detection. Therefore, the objective of this research is to
develop a paper-based cation-selective optode sensor or paper strip as an instrument-free and portable
device for on-site detection of Hg2+
in water samples.
2. Results
The response of the paper strip relies on cation-exchange equilibrium between the aqueous solution
containing Hg2+
and the sensing paper. CU1 induced the extraction of Hg2+
from aqueous solution into the
sensing paper by formation of a coordinated compound. To maintain an electroneutrality of the system,
hydrogen ions of chromoionophore XIV are released from the sensing paper at the same time. Therefore,
the color of paper strip turns from blue (CH+) to yellow (C). The ion-exchange process is expressed by Eq.
1,
(1)
where L and R- are CU1 and KTpClPB, respectively.
The paper strip responded to Hg2+
by changing in color from blue to yellow at pH 5.0 with a response
time of 15 min. The sensor showed excellent selectivity toward Hg2+
over interfering ions including Na+,
Mg2+
, K+, Ca
2+, Cr
3+, Fe
3+, Co
2+, Ni
2+, Cu
2+, Zn
2+, Cd
2+ and Pb
2+. Only Ag
+ can interfere by changing in
color from blue to yellow. However, this interference can be easily eliminated by AgCl precipitation. The
response of the paper strip has usual sigmoidal shape, adjusting the data set to a Boltzmann equation2 with
R2 = 0.9990. The dynamic range went from 6.6×10
-7 M to 5.0×10
-5 M, and the limit of detection (LOD)
calculated with this method was 0.66 µM (0.13 ppm, n=10) which was closed to LOD of Hg2+
detection
calculated from conventional planar film optode3. However, this proposed method was not required any
instruments and provided an easily detection method for on-site analysis. Finally, the paper strip was
successfully applied to determine Hg2+
in real water samples including drinking water, tap water and pond
water with the recovery of 82-119% and %RSD less than 11%. The results are in satisfactory agreement
with those obtained by inductively coupled plasma spectrometric measurements (ICP-OES).

Abstract
Cu2Sn3S7 (CTS) can be used as the light absorbing layer for thin-film solar cells due to its good optical
properties. In this research, the powder, baking, sulfur, sintering (PBSS) process was used instead of
vacuum sputtering or electrochemical preparation to form CTS. During sintering, Cu and Sn nanopowders
mixed in stoichiometric ratio were coated to form the thin film precursor. It was sulfurized in a sulfur
atmosphere to form CTS. The CTS film metallurgy mechanism was investigated. After sintering at 500
°C, the thin film formed the Cu2Sn3S7 phase and no impurity phase, improving its energy band gap. The
interface of CTS film is continuous and the formation of intermetallic compound layer can increase the
carrier concentration and mobility. Therefore, PBSS process prepared CTS can potentially be used as a
solar cell absorption layer.

1. Background
When the inversion layer occurs in the atmosphere, the diffusion of airborne pollutants is limited and air
quality becomes poor. The inversion occurrence and profile of atmospheric temperature around the
discharging chimneys is necessary to be monitored for pollution reduction and environmental governance.
The popular methods used to collect meteorological data are through monitoring by air balls or an
inversion thermometer. Compared with the aforementioned equipment, using unmanned aerial vehicles
(UAVs) combined with sensors (Martin et al., 2011; Gonçalves and Henriques, 2015) is inexpensive and
effective to operate and move according to the results of this study.
2. Methods
First, mount the module of sensors on the top of the multi-axis UAV. The module included sensors of
temperature, relative humidity, PM2.5, GPS, bluetooth transmission, and data logger and processor.
Second, allow the UAV to rise vertically to collect and transfer meteorological data and PM2.5
concentration at controlled altitude levels near the selected chimneys. Finally, the collected data can be
quantitatively rendered in ten minutes.
3. Results
Figure 1 showed the trend of atmospheric temperature and airborne PM2.5 concentration near the
chimney of a steel plant with increasing altitude. The vertical height of this chimney located at altitude of
4.6 meters is 143 meters. The monitoring time was around 8 o'clock at night and its relative humidity was
about 75%. Inversion phenomenon of atmospheric temperature occurred at heights of 192, 235, and 270
meters. It was shown that the dispersible height of the discharged pollutants, such as PM2.5, from this
chimney and the surface only reached to 192 meters. At altitudes in 300 meters, there were multiple
inversion layers detected in time using our method. By immediate alert of inversion layers around the
discharging pipes of factories, effective reduction and impact control of pollution emissions can be
achieved.

* E-mail: [email protected]
1. Background
Over the last decades, the interest in transition metal nanocatalysts has significantly increased because
they can use in numerous fields of chemistry. The broad applicability could be attributed to outstanding
properties of nanomaterial including quantum effect, unexpected chemical, optical, mechanical, electrical
and magnetic property.1 These properties offer researchers the chance to advance the catalytic activity and
stability of nanocatalyst. Since silver nanomaterials have unique properties such as stability, lower cost,
antibacterial activity and higher speculative open circuit potential, those nanomaterials have been widely
used as a catalyst. Furthermore, silver nanomaterials with various size and shape showed an enhanced
catalytic activity in an oxidation of organic matter, epoxidation of alkenes, and photocatalytic reactions.2
2. Results
Figure 1 shows the SEM images of silver nanomaterials prepared by using silver nitrate and different
reducing agents. The resulting Ag nanomaterials reduced by a sodium borohydride were formed in the
shape of a sphere. Figure 1 (a) image shows unclearly sphere shape of Ag nanoparticles, therefore, we
measured TEM and high-performance FESEM so as to obviously obtain a shape of Ag nanoparticles in
Figure 3. At this time, the ionic liquid which acts as both co-solvent and surfactant led to smaller and
more orderly Ag nanoparticles. In order to determine the role of an ionic liquid, Ag nanoparticles were
synthesized without ionic liquid in the presence of sodium borohydride as reducing agent (Figure 1 (b)).
As shown in Figure 1 (a-b), the SEM images clearly show that the average diameter of Ag nanoparticles
without ionic liquid is approximately 98 nm, which are twice as big as Ag nanoparticles using ionic liquid.
Also, in order to verify an effect of reducing agent, we changed the reducing agents such as sodium
borohydride and hydrazine hydrate in same reaction time and temperature. When hydrazine was used, the
Ag nanoparticles were formed in shape of plates with broad size distribution in Figure 1 (c).
We successfully achieved the Ag nanocatalysts with different size and shape in ionic liquid media. The
shape of these catalysts were controlled by using different reducing agents, in actually, Ag synthesized
using sodium borohydride was formed in a shape of sphere for 0.5 h at room temperature. Furthermore,
the hydrazine hydrate as reducing agent built Ag hexagonal plates with indeterminate plates in small size
for 12 h at room temperature. In this synthetic method, the ionic liquid which acts as both co-solvent and
surfactant led to smaller and more orderly Ag nanomaterials. The resulted Ag catalyst exhibited
photocatalytic activity in MO oxidizing as a reaction of water purification under natural sunlight and
visible light (Xe-lamp) irradiation.

1. Background
The demand for wearable devices has increased exponentially in recent years. Stretchable conductive
textiles are an important element in next-generation wearable device [1]. Conductive textiles can be used
as sensors for monitoring human motion through changes in the electrical resistance to varying strain
rates.
2. Methods
In this study, we propose a water-based MWCNTs (multi-walled carbon nanotubes) ink and a
vacuum-filtration process. MWCNTs have excellent electrical conductivity and mechanical strength and
is cheaper than other metallic materials. The vacuum-filtration process is simpler and cheaper than other
manufacturing methods. The textile used to prepare the conductive textile consisted of 93% polyester and
7% polyurethane. Conductive threads were used to form the electrical contact points for measuring the
electrical resistance. The conductive textile prepared by the vacuum-filtration method was attached to the
finger joints of a glove to form a motion-sensing glove. Thermogravimetric gravimetric analysis was
performed to investigate the thermal stability of the MWCNTs before and after oxidation. The defect
variations in the MWCNTs before and after oxidation were confirmed by Raman spectroscopy, and
field-emission scanning electron microscopy was used to examine the morphology of the conductive
textile samples. A stretch evaluation system was constructed to measure the variations in electrical
resistance according to changes in the length of the conductive textile; the stretch evaluation system
consisted of a bending machine and a digital multimeter.
3. Results
The conductive textile prepared by vacuum filtration was evaluated for resistance variations as it was
subjected 10,000 cycles of repeated stretching at strain rates of 0% to 20%. The samples showed good
results with resistance changes of less than ± 3% after 10,000 cycles of stretching. This result
demonstrates that the conductive textile prepared by the vacuum filtration had excellent durability. The
pulse of the resistance variation was uniform, which means that this textile can be applied as a reliable
resistance displacement sensor. A motion-sensing glove was fabricated with the conductive textile
prepared by vacuum filtration. The pulse of the oscilloscope changed accurately according to the
movements of the fingers, demonstrating that the conductive textile prepared in this study can be applied
to motion sensing in real products.

* E-mail: [email protected]
1. Background
The lithium metal battery has attracted much attention as the ultimate lithium secondary battery for high
energy density. However, safety issues and battery performance deterioration due to the growth of lithium
dendrite have hampered the practical use of lithium metal batteries. Recently, lithium fluoride has been
considered as a lithium metal protective layer to solve this problem. In order to form lithium fluoride as
an artificial SEI, coating methods such as deposition [1], liquid reaction [2], and gas reaction [3] are
applied on the surface of lithium metal.
2. Methods
In this study, lithium fluoride was deposited on lithium metal using thermal evaporation method to inhibit
dendrite formation. Thermal evaporation is advantageous in that the deposition rate is faster than that of
sputtering or other deposition methods and the impact applied to the substrate is weak. To verify the
characteristics of lithium metal batteries according to the thickness of lithium fluoride, lithium fluoride
was deposited to the thickness of tens to hundreds of nanometers. To confirm the electrochemical
properties, the symmetric cells (Li│Li) were fabricated to evaluate the time-dependent impedance
change and the potential change over time under the condition of 1 mA/cm-2
and 1 mAh/cm-2
. The Li│
LiCoO2 cells were fabricated by applying LiCoO2 cathode material, which is widely used in industry, and
the stability change according to application of lithium fluoride was evaluated. In addition, the surface
morphology according to the application of LiF was compared through SEM analysis.
3. Results
EIS analysis according to the time and cycle progress showed that the impedance change of bare Li cell
was larger than LiF-coated Li cell. In the cycling stability evaluation using the symmetric cells,
LiF-coated Li cell showed more stable characteristics than bare Li cell at current density of 1mA/cm2.
The SEM images showed that lithium grows roughly on the bare Li metal and the surface morphology of
the LiF-coated Li metal is relatively smooth. In Li│LiCoO2 cells cycling evaluation, LiF-coated Li cell
showed more stable cycle performance than bare Li cell and suggested possibility for practical use.

1. Background
Wind power plays an important role in the renewable energy development of Taiwan. It is disclosed from
the government planning reports that wind farm development, related standards & design verifications,
and the operation & maintenance of wind turbine are important issues that should be studied carefully. In
addition, those issues are related closely to the reliability engineering and statistics. To this end, this study
intends to apply the reliability engineering to the development of wind power industry. However, in this
stage, analysis of collected wind data with statistics and reliability techniques is the major task.
2. Methods
Several well-known probability density functions (PDF) including Normal, Log Normal, Weibull,
Rayleigh, Gamma, Bimodal Mixture Weibull are chosen to best fit the wind-speed data in this study. In
the estimation of parameters for each probability density function, the maximum likelihood (ML) method
is used. To better understand the characteristics of wind such as the wind direction and its associated wind
speed, which is crucial to the design of single wind turbine tower as well as the deployment of a set of
wind turbines, the rose diagram is adopted and drawn. The wind power density that is a quite important
indicator for developing the wind farm is also evaluated. In addition, the turbulence intensity (TI) which
can be quantified with the wind data and the normal turbulence model is calculated to help the design of
the wind turbine.
3. Results
In the present study, works carried out and results obtained based on collected wind data of a particular
wind farm in Taiwan are summarized as follows. (1) Fitting of wind-speed by several probability density
functions. (2) Construction of wind-rose diagram and evaluation of wind power density. (3) Investigation
of wind-speed variation in different elevations. (4) Disclosing the joint probability density of wind-speed
and wind-direction. (5) Preliminary investigation of extreme wind speed in consideration of Gumbel’s
order statistics. (6) Investigation of turbulence intensities and examination whether the result is in
compatible with the specification of IEC 61400. The conclusion in this stage is that a bimodal mixture
Weibull distribution can better describe the wind speed of the particular wind farm than Weibull
distribution which is frequently used in specifications and the design of wind power systems. It is also
found that, as predicted from aerodynamics, wind speed does increase along with elevation, but the
distribution style remains similar. If a 50-year return period is considered, it is found the expected
extreme wind speed is 46.5 m/s. It is also concluded that turbulence intensities of the wind farm are in
compatible with that required by IEC 61400. It indicates that the wind farm is worth being developed.

Abstract
Power facilities are important social infrastructures, and they must maintain their functions even in the
event of a natural disaster. As power supply is required for swiftly carrying out reconstruction projects
made necessary by the occurrence of natural disasters like earthquakes, the seismic stability of power
facilities is very important. In this study, the seismic performance of the cable termination facility, a
power facility, was evaluated using the shaking table test. In addition, the results of the shaking table test
were applied to a finite element model for the conduct of seismic response analysis. The maximum stress
values obtained from the shaking table test and finite element analysis were lower than the allowable
stress of the material and met the acceptance criterion suggested by IEEE Std. 693:2005. Furthermore, the
finite element analysis showed maximum stress values higher than those obtained from the shaking table
test. Therefore, it was confirmed that the seismic safety of cable termination facilities can be evaluated
using finite element analysis.

1. Background
Solar power is a key development for the purpose of the global sustainability trends in renewable energy
but raises level of uncertainty in power systems. However, influenced by factors of geography and
circumstance, the solar power has the characteristics of intermittency and uncontrollability. Therefore, the
study of solar power forecasting technology for assisting power system operation is becoming important.
The solar power forecasting is an important measure to solve this problem and to ensure the reliable
operation of a power system which is significantly fed. Power dispatch plays a very important role for
better decisions in system and to secure the reliable and stable energy supply. The solar power forecasting
is an important for power system and helps to improve the reliability and also reduces the generation cost.
2. Results
The RBFNN has the capability of dealing with varied and complicated relations between input and output
data, and Particle Swarm Optimization (PSO) helps with the appropriated regulation of weighting
parameters to improve the forecasting results. In addition, proper parameter settings of RBFNN is
important to its efficiency and accuracy. In this paper, use the PSO to perform the parameter optimization
for RBFNN, which not only improve the solar power forecast model availability and improve the
forecasting accuracy. Simulation results provided a short-term solar power forecasting and demonstrated
the effectiveness of the proposed method in a volatile environment. RBFNN has the capability of dealing
with varied and complicated relations between input and output data, and PSO helps with the
appropriated regulation of weighting parameters to improve the forecasting results. The data of solar
power were used to demonstrate the performance of RBFNN and PSO and integrated historical data and
central meteorological bureau data to forecast solar power. For case study, it proved that RBFNN and
PSO have the capability to produce better results for volatile solar power forecast.

1. Background
Robusta coffee is one of popular agricultural crops, especially in southern Thailand. Normally, Robusta
coffee is internationally traded as green coffee bean, which is produced by dry processing. From dry
process, it provided the unwanted material which was mixed into the green coffee bean such as parchment
coffee (Prata & Oliveira, 2007). Parchment coffee separation from the Robusta green coffee bean is the
important process because it can increase the value of Robusta green coffee bean. It can also decrease the
problem in the coffee processing especially roasting process. Therefore, the objective of this work was to
investigate the effects of sieve angle and air velocity on the separation efficiency of parchment coffee
from Robusta green coffee bean using pneumatic separation machine combined with vibrating sieve. The
loss percentage, weight purity index and specific energy consumption (SEC) were also investigated.
2. Results
The experimental result showed that the pneumatic separation combined with vibrating sieve can help the
separation efficiency to be higher due to the vibrating sieve provided the good distribution of materials
(Delaney et al., 2012). The air can easily blow through the materials. The air velocity and the sieve angle
significantly affected the performance of pneumatic separation machine combined with vibrating sieve.
The separation efficiency, loss percentage, weight purity index were higher with increasing air velocity.
The higher air velocity provided the parchment coffee to be easily removed, leading to higher separation
efficiency and weight purity index. However, the green coffee bean was more blown out to the parchment
coffee tray when increasing air velocity. Therefore, the loss percentage was also higher. In addition, the
increase of air velocity provided the increase of SEC value. This is because of higher energy requirement
value. In term of sieve angle, the increase of sieve angle provided the lower value of separation efficiency,
loss percentage, weight purity index as well as SEC. The higher sieve angle provided the faster movement
of materials (Kannan et al., 2016), leading to the shorter time for separation and resulting in the lower
value of separation efficiency, loss percentage, weight purity index and SEC.

1. Background
Hyaluronic acid (HA) or hyaluronan is one of the glycosaminoglycans that consists of repeating units of
N-acetyl-D glucosamine along with glucuronic, which is linked by glycosidic bonds [1]. HA is a linear
and high molecular weight polysaccharide. In cosmetic products, HA has been utilized due to viscoelastic,
free radical scavenging properties and good biocompatibility [2]. In addition, the concentrations of HA
added in cosmetics are up to 1% [3]. Therefore, the determination of HA in cosmetic samples is
necessary because it helps for quality control of products in both manufacturing process and the markets.
The aim of this study is to develop a simple capillary electrophoresis (CE) method for determination of
HA in cosmetic samples.
2. Results
HA was detected from cosmetic samples, which diluted to 100 times with 10% v/v BGE. The results
showed good separation because of no matrix to interfere the signal of analyte. The analysis time was
achieved at approximately 8.5-8.7 min. For quantitative analysis of HA, the standard addition method
was used to construct a calibration curve, which was in the ranges of 50-250 mg L-1. Limits of detection
and quantitation of the proposed method for determination of HA were 1.0 and 3.0 mg L-1
, respectively.
In addition, intra-day (n=5) and inter-day (n=3) precisions were investigated and found that the
percentages of relative standard deviation of the corrected peak area at 60, 120 and 180 mg L-1 HA were
0.8, 0.9 and 1.9% (for intra-day) and 3.1, 3.4 and 6.5% (for inter-day), respectively. The developed
method was applied for determination of HA in cosmetic samples and found that the recovery percentages
of HA were in the range of 80.5 to 91.6%, indicating high accuracy of the method. Therefore, the
developed method was reliable and simple without complicated sample preparation. Moreover, this
method can be possibly applied in cosmetic industry for quality control of products.

Abstract
Acoustical measurements and recordings were made during 15 lectures in 11 university classrooms at
Kangwon National University in Korea. A statistical method modified by Sato and Bradley (2008, JASA)
was used for obtaining octave band speech and noise levels in university classrooms during lectures. In
the 11 active university classrooms the students experienced: speech levels of 51.5 dBA (s.d.=2.7 dBA),
noise levels of 44.3 dBA (s.d.=2.1 dBA), and a speech-to-noise ratio of 7.2 dBA (s.d.=2.7 dBA). The
results showed that the speech and noise levels were 0.7 dBA higher and 0.1 dBA lower than in the 11
UBC classrooms (Hodgson et al, 1999).

Department of Biomechatronic Engineering, National Ilan University, Taiwan
E-mail: [email protected]
1. Background
In the past decade, the egg industry suffers severely labor shortage in Taiwan. Although the egg
washing/packing automation system had been introduced into some large companies, egg shipping boxes
are still moved onto pallets by porters. A porter may move up to 2 or 3 tons of goods per day in a
commercial egg packing factory. This work is heavy and harmful to the porters. Automation using robot
might be a feasible way to replace human. In order to satisfy the different customer’s need, various
products with various shipping boxes and their corresponding pallets, and even the piling methods, will
coexist in the egg packing production simultaneously. The product diversity makes the automatization
complex and difficult because it conflicts with the golden rule “standardization” and “simplification”. The
objective of this research was to develop an automated flexible transportation system for egg shipping
boxes to overcome the overcome the problem.
2. Methods
This study develops an automated flexible transportation system for egg shipping boxes. The system was
divided into four major parts: (1) a new conveyor was set up to transport the egg shipping boxes form the
packing lines to the pallet area. (2) A product identification station was located on the conveyor in front of
the pallet area. This station detected the RFID tags on the shipping boxes, identified the type of products
and its corresponding setting weight, and sent the command to robot to move and pile this boxes. (3) A
robot moved the boxes to the assigned pallets based on the type of product. The unqualified boxes would
be bypass by the robot and be conveyed to the inspection area at the end of conveyor. The worker would
recheck the contents in the unqualified boxes.
3. Results
The intelligent flexible transport system was set in a commercial egg factory with 16 egg packing lines
and the production capacity of 400,000 eggs/day. This system was designed to manage the transportation
of eight different type of shipping boxes on four different size of pallets and 14 corresponding piling path
of robot. In each batch of production, the robot would handle three different types of product to their
assigned pallets. The transport capacity of the robot should be more than 240 boxes per hour, or 2,000
boxes per day, almost equal to 8 to 10 workers. This system alleviate the urgent manpower requirement
and the reduce risk of occupational injury in egg packing factory. It will also provide an inspection
mechanism to detect the human error in the box-packing process.

1. Background
The elevated jet in crossflow (the transverse jet) has been studied extensively because of its widespread
applications, for instance, combustion, mixing, cooling, stack flare, and propulsion devices (e.g., Pratte &
Baines 1967, Fric & Roshko, 1985). The mixing of jet with crossflow played a major role in the
applications. The acoustic excitation to the jet was used in the present work to study the characteristic
flow behaviors and mechanism for mixing enhancement.
2. Results
Figure 1 shows typical instantaneous flow patterns in the median plane of the non-excited elevated
transverse jet at the jet-to-crossflow momentum-flux ratio R = 1.2 obtained by the laser-assisted
smoke-flow visualization technique. A clear counterclockwise-rotating vortex train appears on the upwind
shear layer of the deflected jet after the jet left the tube-tip. This vortex train does not appear stably. It
appears intermittently and disappears sometimes without periodicity. This type of flow structure occurs at
R > 1. The deflected jet column near the tube exit is coherent. The jet fluids start to disperse and expand
appreciably as the jet column is bent over. The natural-state of the shear-layer vortices does not cause
large dispersion of jet fluids. Figure 2 shows the flow pattern in the median plane of the transverse jet
excited by the sound waves at an off-resonance frequency. The crossflow impingement deflects the jet
column near the tube exit. The jet fluids in the downstream area present large up-down oscillating
motions. The frequency of the bent jet oscillation is synchronized with the forcing frequency of the
acoustic excitation. The jet pulsations induce back-and-forth flapping motions of the jet column near the
tube exit. As the jet column near the tube exit tilts up, a vortex is induced downstream of the tilting jet.
The periodically created vortices propagate downstream and cause the deflected jet to oscillate. The
flow-visualization pictures shown in Fig. 3 are for the resonance frequency excitation, which presents
crowded puffs as the jet column near the tube exit is flapping back-and-forth quickly. The puffing
frequency is the same as the resonance frequency. The large excitation intensity at the resonance
frequency makes the jet flow penetrate to high elevation and hence the spread of the smoke in the
transverse direction looks wider than that in Fig. 2. The measurements of carbon monoxide concentration
show significantly higher mixing efficiency than that of the non-excited transverse jet as the jet is
acoustically excited, particularly excited at resonance frequency.

E-mail: [email protected]
Abstract
The paper presented the propagation characteristics of graded phononic crystals with smart material. The
acoustic waveguide characteristic of the graded phononic crystals is used to design some novel acoustic
devices and the composite system combined with graded phononic crystals structure. Besides, the graded
phononic crystal system is composed of circular cylindrical with air background in this study.
At first, the effective refractive index of the phononic crystal system can be tuned by adjusting the filling
ratio because that periodic structure behaves like a homogeneous medium, since dispersion relation is
almost linear in long wavelength limit assumption. Then, the plane wave expansion method is utilized to
calculate the band structures of the graded phononic crystal. Thus, the effective refractive index of the
graded phononic crystal with various filling rations can be obtained. The smart materials can be used in
graded phononic crystal structure to design more effective acoustic waveguide devices. Additionally, it
also can be adopted to study other types of graded phononic crystal devices with various smart materials
based on the numerical and experimental results of this paper.

1. Background
Urbanization and its overcrowding has changed disaster environment by spreading the urban area to the
steep slope (or mountain slope) and the reservoirs that had existed in the rural area in the past. Collapses
of those steep slopes of the mountains and the reservoirs are likely to cause a wide range of complex
disasters. Those should be considered by preliminary disaster impact assessment at a stage of urban
development plan. However, the preliminary disaster impact analysis has been performed only for single
disasters, not complex disasters. It is only dependant on qualitative judgment of the committee members.
This study mainly performed some precedent research on the development of GIS-based risk management
tool for multi-disasters induced by landslides and ole reservoir collapse.
2. Results
This study was performed with a purpose of developing a GIS-based complex disaster risk assessment
tool estimating the losses from multi-disasters caused by steep slope landslides and old reservoir collapses.
It is mainly supposed to firstly develop risk assessment criteria to identify whether there is a need for risk
mitigation, to develop cost-benefit analysis tool to judge whether t is an acceptable risk or not, to identify
GIS-based qualitative/ quantitative risk analysis tools, and then to estimate loss. Through these processing,
an amount on the damages induced by multi-disasters can be finally estimated. Based on these steps, it
can be expected that the risk assessment and management for slope landslides and the collapse of old
reservoirs is performed in both qualitative and quantitative way.

Study on Cumulative-Hazard Risk Assessment Based on Reliance Between Single Natural
Disaster

Cuber Solution Ltd., Republic of Korea
* E-mail: [email protected]
1. Background
The scale of natural disasters has been recently increasing due to climate change and rapid urbanization.
Their characteristics have become complex by combination of natural disaster and substantial social
disasters (Agusomu and Paki, 2011). Those complex disaster have defined as cumulative-disaster and the
increasing damages induced by the cumulative-disasters are resulted in the growth of interest in risk
assessment and management for cumulative-disasters (CRED, 2013). Since the cumulative-disasters have
occurred as a result of multiple or simultaneous natural disasters and social disasters, as a first step to
assess the risk of the cumulative-disaster, it is essential to analyze the causal and reliance between
disasters (Farrokh Nadim and Zhongquang Liu, 2010). Therefore, this study mainly analyzed the
reliance between single disasters for the risk assessment of cumulative-disaster. This is evaluated by
establishing a scenario of complex disaster and assessing the risk of cumulative-disasters based on their
reliance.
2. Results
This study mainly assessed the risk of cumulative-disaster by using the Delphi technique. Fistly, the
reliance of single disasters are calculated and the virtual scenario is established. Finally,we proposed a
new method for assessing the complex risk due to cumulative-disasters using the reliance on
inter-disasters. The risk assessment method is specified and supplemented in consideration of frequency
and intensity of disasters. In the future, we will improve and extend the scenario by raising the reliability
of the group of specialists surveyed by each disaster.

E-mail: [email protected]
Abstract
At the time of localized torrential rains, wood on a mountain surface is washed onto rivers and these
driftwood in rivers aggravate the flood events. For example, large driftwood blocks the river, which lead
to increased water levels and flooding of the nearby areas. Therefore, some previous researchers have
investigated the driftwood capturing structure to remove woody debris from the river.
In the present study, we considered the driftwood capturing structure by using an anti-flood pond. The
laboratory flume experiments were conducted and we investigated the driftwood trapping probability in
the anti-flood pond. The results indicated that the trapping probability is highly influenced by the groyne
position.

Taipei, Taiwan
* E-mail: [email protected]
1. Background
Powder metallurgy (PM) technique is a versatile process to economically fabricate metallic materials in
mass production. However, the presence of pore, which impairs the mechanical performances, in the PM
materials is the most important issue to overcome. In general, the porosity of the PM steels ranges from 5
vol% to 15 vol% [1,2]. The pore acts as a stress or strain concentrator and leads to inferior mechanical
properties [3]. Unfortunately, the effects of the pore and the microstructure on the strain distribution have
not been clearly studied to date. The objective of this study was thus to investigate the influence of
microstructure and pore feature on the partition of strain during tensile testing. Two PM steels including
pure Fe and Fe-0.43C were analyzed in this study.
2. Results
The microstructure of the pure Fe specimen was fully ferrite, and the porosity was 10.9 vol%. The pores
in the Fe sample were very irregular and large. From the DIC strain mapping of the Fe sample, it is clear
that the strain concentrated at the original powder peripheries and sintered necks. The strain gradually
extended into the powder interior with the increase in the tensile stress. Ductile fracture on the sintered
neck was definitely identified by SEM. On the other hand, the microstructures of the Fe-0.43C steel were
ferrite and pearlite, and the porosity was 11.2 vol%. In the Fe-0.43C steel, the strain was also
concentrated in the ferrite. No obvious strain in pearlite could be found. The fracture surface/path also
indicates that the pores near ferrite was the dominant fracture site in the ferrite/pearlite steels. This results
also proves that the presence of pearlite in the steel can increase the tensile strength of the steel, though
the ductility was degraded. Therefore, the strain and fracture were non-uniform and were localized in the
ferritic area. In conclusion, DIC technique was very useful for evaluating the microstructure responsible
for the strain and provide valuable information for microstructural design of PM steels.

Mao Zedong during the Rectification Movement in the Yan’an Period
Wei-Li Wu

E-mail: [email protected]
1. Background
“The east is red as the sun is rising. China has brought forth Mao Zedong.” Mao Zedong is a legend in
modern Chinese history. He rose from an assistant librarian to the leader ruling over China within a few
decades, dominating the destiny of hundreds of millions of people. Reflecting upon Mao’s political career,
he displayed military talents early on, but was excluded by the Bolsheviks who returned from the Soviet
Union. However, during the Long March, he regained military power because of his correct military
strategy. With respect to the power of the party, he had been locked in a struggle with the
“Internationalists,” and it was only until the early Yan’an period that reversal of events became unlikely.
However, “with power to spare we must pursue the tottering foe,” Mao relentlessly pursued and attacked
Wang Ming who refused to make self-criticism. At the time when thinking was yet to be united, Mao
launched the “Rectification Movement” with the aim to overhaul the high-level leadership within the
party, and “seizing this opportunity” to spearhead the campaign to grassroots. After this “spiritual”
cleansing, “Mao Zedong Thought” came to reign supreme in the party, which was like a rehearsal of the
“Cultural Revolution” many years later. Mao, through this campaign, firmly gripped the party, as well as
political, and military powers. This study takes the “Rectification Movement” as the background, and
attempts to clarify the theoretical foundation and means of Mao with a view to establishing the
relationship between Mao Zedong and the “Rectification Movement.”
2. Conclusions
The Yan’an Rectification Movement was the key that Mao was able to concur the whole country, and
smile proudly with his position as secure as Mount Tai after the establishment of the People’s Republic of
China. The campaign model of the Yan’an Rectification Movement also influenced the operation of the
political movements in subsequent decades. Such influence could hardly be over-emphasized.
In the Yan’an Rectification Movement, through his own learning and innate personality, Mao employed
many tactics and means. With the conclusion of the Rectification Movement, Mao obtained immense
power that fused together the military and the party, similar to the nuclear fusion that was about to
produce formidable power. Mao at this time had become every inch a “sage-philosopher” in the eyes of
Edgar Snow, like a never falling red star that shone over all of China.

Public Communication of Green Energy and Low Carbon Technology - A Study on the
Propaganda for National Renewable Energy Policy in Taiwan
Cheng-Neng Lai
Department of Public Relations and Advertising, Shih Hsin University, Taiwan
E-mail: [email protected]
Abstract
Taiwan relies on imports for up to 98% of its energy because lack of energy resources. In addition to the
worries about nuclear energy, renewable energy has become the most popular and important solutions in
the world in recent years. Although there are more than 70% of Taiwanese support to use renewable
energy, the relevant policies and infrastructures could be rejected by a minority of local groups or the
inhabitants in remote regions. The reasons against to build a renewable-energy power plant are mainly
caused by the misunderstanding or bias about the development of energy. Taiwan government, which is
conducted by the Ministry of Science and Technology (MOST), executed the National Energy Program
(NEP) to develop the green energy and to do an effective communication with the public about the
positive use of renewable resources in Taiwan. The "Public Communication of Green Energy and Low
Carbon Technology" is mainly used to publicize the fields in renewable energy and popular science
communication. The public will understand the importance of low-carbon emissions and green energy,
and then turns to support the national energy policy through an effective communication with the
professional and multiple opinions in all aspects of renewable energy.
In order to effectively reach the goals on the technology innovation and policy promotion of green energy
in Taiwan, and to create a friendly environment with low-carbon emissions and developing the relevant
green industries, this study will aim as follows:
A. Design visual communication materials to promote green energy: some of professional, lively, and
easy to understand new popular media materials such as infographics, info. for dummies, cartoons
and animation will be introduced in this study. It will help people to learn more about the popular
science of green energy and low-carbon knowledge with the necessity for development of green
energy and low-carbon technology in Taiwan.
B. Build a social media website for green energy and popular science about low-carbon technology: a
few official online communication tools such as MOST Facebook, Wow Knowledge, Wow Energy
NEP-II, will be introduced to the public. These two-way communication platforms can effectively
respond to current issues and helping people to learn more about green technology.
C. Public relations and propaganda on green energy and low-carbon policy: an effective and interactive
communication will be conducted to promote the green energy and low-carbon policy through some
face-to-face workshops or a live broadcasting. The highlights of NEP-II and its executive results will
be discussed and presented via different public relations platforms with current issues or depth
reporting articles reported on electronic and traditional media.
This study found the public may change their negative thought and attitudes to support the green energy if
they learned some clear and objective statements, infographics, cartoons or science films with pros and
cons about new energy. The development of national energy is a long-term program and green powers
must bring benefits to the society. Through the appropriate popular science media and knowledge sharing
materials to the public, especially for the elder inhabitants and kids in remote regions, the
misunderstanding and stubborn bias against to develop the green energy or renewable resources could be
decreased or dismissed in future Taiwan.

1. Background/ Objectives and Goals
Research activities conducted by clinical nurses are an important part of continuing education as quality
improvement through the practice of evidence based nursing (EBN) is expected. The barriers for the
clinical nurse to perform these studies include time constraints, insufficient knowledge of the current
literature, lack of authority to change practice, a deficit of critical appraisal skills, and inadequate support
for the implementation of research findings(Huchinson and Jhonston, 2004).Therefore, since 2007, the
Sapporo City University has supported nursing research. Previous studies noted that supporting a nurse
based on her level of research knowledge provided an intervention effect toward implementation of a
given program (Higashino, et al., 2016). While there are reports on the requirements for entire projects,
detailed specific needs have not been explored. The purpose of this research is to describe the specific
needs of nurses to pursue research and to clarify the future activities to support research.
2. Expected Results/ Conclusion/ Contribution
In total, 177 nurses completed the survey for analysis (response rate, 65.8%). The mean number of years
of work experience was 14.9 (standard deviation, 8.2). The mean number of research projects was 4.9
(standard deviation, 4.5), with 50.8% respondents being the staff nurses. The ethics review question had a
median score of 3 with intermediate difficulty. The data analysis question had a median score of 5 with a
high degree of support needed. Presentation had a median score of 3 with a moderate degree of support
required. Methods and data analysis both had median scores of 5, indicating that a high degree of support
was necessary. A total of 86.3% respondents received support in determining the methods of their studies.
There were very few responses to the questions about presentation and submission of the manuscript
because not many nurses could get that far in the process. The area with the least satisfaction about the
support received was literature review with only 83.1% satisfied; however, 98.1% were satisfied with the
support received regarding ethics review. About 94.3% respondents believed that assistance was needed
from the university with training to conduct follow-up, whereas only 79.0% believed that assistance with
motivation was necessary. Our results indicate that the following factors must be addressed to support
research by clinical nurses: teaching method, reviewing the literature, selecting an appropriate research
method, and analyzing the data. Our results also demonstrated that there was dissatisfaction with the
methods of communication used. To respond to the needs for research support from the university, it will
be necessary to consider clinical human resource development.

Rental Device’s Management by Using Barcode Application System
Yu-Hsuan Hsu, Yi-Cheng Hsieh
Changhua Christian Hospital
E-mail: [email protected]
1. Purpose
The rapidly changing medical industry has dramatically changed the way hospital operate. In
collaboration with the medical device manufacturer, adopting short-term lease not only reduces hospital
cost, but also ensures the medical technology is updated in a timely manner; however, the management of
rental equipment cannot be ignored. At present, the barcode system is widely used in hospitals for
surgical instrument management. If the barcode system can be applied to the management of rental
equipment, it can further improve patient safety.
2. Situation
Traditionally, the operating room rental device registration flow sheet must be filled in by hand, including
the date of surgery, the surgeon, the operation time, the patient's name, the name of the brand, the name of
the device, then fill in the number of boxes and the estimated delivery time after contacting the
manufacturer. After the manufacturer delivers the device, the manufacturer must fill in the external
delivery device receipt, including the surgeon, patient name, medical record number, operation date,
brand name, and device name... then attach it to the device packaging. All checklists must be manually
filled in repeatedly, which is time consuming and difficult to keep track in the future.
3. Method
Operating room staff can use the surgical scheduling system to confirm the rental equipment’s brand and
name the day before. The relevant information is transmitted from the operating room to the Central
Sterilization Supply Department. In order to effectively identify and track the device, it is cleaned by the
Central Sterilization Supply Department upon its delivery by the the manufacturer and a sticker
containing patient’s name is printed and attached to the equipment.
4. Conclusion
The traditional handwritten checklist method not only increases the staff’s workload, but also raises the
issue regarding legibility of the writing and paper waste. Moreover, it is impossible to accurately track the
equipments use by the patient. The barcode system has been widely used in operating room equipment to
track and manage rental equipment and also transmit relevant information. In addition to printing a
barcode sticker containing only the patient’s name, the system can also be programmed to print a
complete message delivery slips. Therefore, the operating room staff can be more clearly assigned and
information delivered by the Barcode system is more complete.

Impact of Retailer’s Selling Advantage on Manufacturer’s Channel Selection

E-mail: [email protected]
1. Introduction
A central question in the domain of supply chain management and marketing is the manufacturer’s
distribution channel selection. Dell operates the direct channel in terms of either brick-and-mortar or
online store to sell PCs. The phenomena that manufacturers selling exclusively through independent
retailers widely expand across different product categories, e.g., Acer, Colgate, Gillette, Heinz, Kelloggs,
and Tylenol (Hsiao and Chen, 2014). Besides these, manufacturers have been competing with retailers at
the retailing layers for many years in different forms, e.g., company-owned franchises, catalog sales,
online stores, and factory outlets (Arya et al., 2007). Opening direct channels usually involves
manufacturers’ significant investments in destabilising the direct channel and adopting retail practice (Ha
et al., 2016). Whereas channel selection decisions on both the manufacturer’s (Cai, 2010; Khouja et al.,
2010; Hsiao and Chen, 2014) and the retailer’s sides (Wang et al., 2016) have been extensively
investigated and well understood, the impact of retailer’s selling advantage on channel selection with
specific features has been completely ignored and received no attention in existing literature. In
comparison with the manufacturers suffering from inexperience, inefficiency in retailing operations, or
the extra cost of opening e-commerce channel., traditional retailers usually have a selling advantage in the
sales and marketing process, which is stemmed from the fact that the retailer has superior knowledge of
customer preferences, more direct contact with customers, or economies of scope with other retailing
activities.
The primary purpose of this study is to bridge this gap by systematically comparing channel selection
decisions under the following four different supply chain structures proposed by Cai (2010) while taking
the retailer’s selling advantage into consideration to facilitate our analysis:
— a manufacturer-owned direct channel (Scenario D);
— a traditional single-manufacturer-single-retailer retail channel (Scenario R);
— a supply chain with two traditional retail channels (Scenario RR);
— a dual-channel supply chain with a traditional retail channel and a manufacturer-owned direct
channel (Scenario RD).
More specifically, we seek to address the following research questions:
(i) How would the retailer’s selling advantage affect the manufacturer’s channel selection decision?
(ii) How would the retailer’s selling advantage affect the retailer’s and consumers’ preferences
among different channel structures?
The main contributions of the present study are summarized as follows. First, the manufacturer’s optimal
decisions of channel selection are dual-channel, while the precious choice evolves around the
distributions of its selling cost. More specifically, the manufacturer chooses a mix of a traditional retail
channel and a direct channel when the selling cost is sufficiently small, and two traditional retail channels
when the selling cost exceeds a specific threshold. This approves the statement that retail competition is
typically viewed as a healthy economic driver (Arya et al., 2007). Second, we observe that the optimal
choices for the retailer are an exclusively retail channel or the configuration of a traditional retail channel
and a direct channel. Third, consumers favor the retail competition, that is, in the forms of two traditional
retail channels and the mix of a traditional retail channel and a direct channel.
The rest of this paper proceeds as follows. Section 2 describes the key elements of our model. Section 3
provides the basic results. Section 4 presents the central analysis. Section 5 concludes this study.

Abstract
Dental malocclusion is an distortion in dentofacial growth or an abnormal relationship between the teeth
and dental arches. Malocclusion could led to obstacles for the patient in terms of physical function, the
teeth which were not well arranged could be a good place to accumulation of residual food, so it could
caused caries and periodontal disease. Malocclusion can be affected with aesthetics, especially in class II
division 1 because of the convex of facial profie, resulting unattractive face and had an unfavorable
impact on a teenager’s psychological development. Adolescence is the time of crisis and seek an identity
with the case of malocclusion is more likely to be a victim of bullied in school so that could effected to
long- term psychosocial impact. This research was to investigate the influence of dental maloclussion
class II division 1 on the psychosocial impact among Junior High School Students in Makassar, Indonesia.
The study was conducting as an analytic observational with cross-sectional study design. Sample of this
research were 1st and 2
nd year of YP-PGRI junior high school students, Makassar, Indonesia. The p value
of this research was less than 0.05, there for the results of this research are statistically significant.
Hypothesis was accepted and showed that there was an influence of dental malocclusion Class II division

With the advent of the digital age, the application of information technology has become an inevitable
trend. Virtual reality (VR) incorporated into teaching, the development of new teaching models, the
cultivation of students’ self-directed learning, and the implementation of teachers’ use of interactive VR
teaching have also become new-generation teaching trends. Therefore, this study adopted E-learning
technology to enhance high school students’ mathematics learning motivation. With the “simultaneous
linear equations in 3 unknowns” unit as the example, this study presented the eight stereoscopic
corresponding models in three planes which are difficult to display in two-dimensional teaching, allowing
students to watch and operate in VR. This not only enhances students’ self-interaction in learning, but also
incorporates gamification to elicit students’ interest in math learning, thereby improving their motivation
to learn and at the same time reducing the burden and inconvenience brought upon teachers in material
preparation and related problems. The test process in this study includes a pretest, an experiment, and a
posttest. In the pretest questionnaire, Keller’s ARCS motivation model was adopted, with four dimensions
designed to gain an insight into students’ math learning motivation prior to the test. Then, the students’
were given a chance to operate a set of VR-aided learning materials which was setup in this study. The
VR-aided learning materials consisted of five units. In Unit 1 and Unit 2, the students in the VR
environment interacted with a flat screen showing a film. The content of the film was a 3-D model
extended from Escher’s illusion works. The 3-D model provided for students to observe served the
purpose of letting students understand the differences between 2D and 3D and how 3D models achieve
illusion through these differences. Unit 3 included eight dimensional models with three planes. Students
could deconstruct these models to understand how they were stereoscopically combined. Before starting
the next unit, the high school math teacher first conducted a 40-minute math class taught using the
conventional way. At the end of the class, the students were given Unit 4 and Unit 5. Unit 4 was a
question and answer game with eight dimensions in three planes. The questions were in three-dimensional
diagrams frequently seen in daily life. The purpose was to relate to students’ daily lives and facilitate
understanding and association. Unit 5 was a “simultaneous linear equations in 3 unknowns” question and
answer game. The purpose was to enable students to understand the association between “simultaneous
linear equations in 3 unknowns” and “graphs”. The design of these two units incorporated the
gamification element. First, the students were requested to answer all the questions within a given time;
otherwise, the train in the game would crash and end the unit. Then, after the end of both units, the leader
board of total scores for correct answers appeared to increase the fun of peer competitions. At the end of
the five units and conventional lecturing, the students filled out a learning motivation posttest
questionnaire. The questionnaire also adopted Keller’s ARCS motivation model to investigate the
students’ math learning motivation situation after completing the teaching material in the research design.
The Likert 5-point scale was used to analyze whether the students’ learning motivation increased The
overall test, including the pretest, the experiment, and the posttest took about 150 minutes to complete.
After the test, the study adopted the independent sample t-test to carry out an analysis and compare
differences in learning motivation before and after applying VR teaching aids in the course. The research
results show that although “the application of VR digital teaching material in high school math teaching”
and “enhancing the math learning motivation of high school students” showed no significant correlation,
the average score showed the students’ math learning motivation increased. Finally, based on observations
during the test conduction process and the class teachers’ interviews, it was inferred that the application of
VR digital teaching material in high school math teaching enhanced the students’ learning motivation. In
the future, the overall teaching aid design and usability will be optimized, thereby improving the overall
performance and specific recommendations that aid follow-up upgrade and revision will be proposed in
order to serve as references for schools, teachers, digital teaching aid development, and related studies.

1. Background/ Objectives and Goals
The purpose of this study was to examine the structural relationship among mother-child interactions,
father-child interactions, self-esteem and happiness of first grade children in Korea. In addition, we
attempted to examine the difference of variables between boys and girls.
2. Methods
Analysis of 1,361 households was conducted using t-test, correlation analysis and structural equation
modeling. Samples originated from eighth (2015) wave of the Panel Study on Korean Children (PSKC).
3. Expected Results/ Conclusion/ Contribution
The main results were as follows. First, it was found that boys showed higher level of happiness and
self-esteem than girls. The degree of mother-child interaction and father-child interaction were not
different between two groups. Second, child’s happiness was highly correlated with self-esteem,
mother-child interaction, and father-child interaction. Third, the results of structural equation modeling
analysis indicated that the mother-child had not only direct effects on children’s happiness, but also
indirect effects through the medium of children’s self-esteem. Father-child interaction had an indirect
effect on child’s happiness, mediated by child’s self-esteem. That is, child’s self-esteem had partial
mediating effect on the relationship between mother-child interaction and child’s happiness, and also had
a full mediating effect on the relationship between father-child interaction and child’s happiness. Fourth,
the results of multiple group analysis indicated that there was no difference in path weights between boys
and girls. These results indicate that mother-child interaction has a greater impact on the children’s
socioemotional development, but father-child interaction should not be ignored. The implications of these
findings were also discussed.

1. Background
In Taiwan, there have been many incidents of food safety that has caused the public to doubt and distrust
food production. People are becoming ever more conscious about food safety as its impact on consumers
isn’t merely on the psychological and physical level, but also encompasses risks to their lives; it can also
indirectly affect the understanding and reaction of consumers towards the risks of food safety. However,
Taiwan’s food traceability measures have been implemented for a long period, but food safety issues has
further emphasized the public’s attention to food traceability.
2. Methods
As CVM can evaluate unrealized market benefits, it’s suitable for this study in evaluating the public’s
willingness to pay to reduce health risks and their acceptance of a comprehensive food traceability system
(such as food traceability and graded certification labels).
3. Expected Results
The empirical results show that: (1) women are willingness to pay more cost for the food certificated label
attention. (2) The most important food marked name is listed below: certificated label, materials, calories.
(3) As a whole, almost average 30% respondents can absolutely understand the food traceability
information.
