The purpose of this study is to investigate the relationship between children and adolescents' moral emotions - empathy, guilt and gratitude - and helping behavior. For this study, questionnaires on empathy, guilt, gratitude and helping behavior were administered to 938 students in the 4th, 5th, 7th, 8th, 10th and 11th grades attending elementary, middle and high school in Seoul and Gyeonggi Province. The data were analyzed through frequency analysis, mean, standard deviation, t-test, one-way ANOVA, Pearson's correlation, enter multiple regression analysis and hierarchical multiple regression analysis by using SPSS Win 12.0. The main findings of this study are as follows: Firstly, by gender, empathy, guilt and helping behavior differed significantly, also, by grade, empathy, guilt, gratitude and helping behavior differed significantly. In addition, religion made a significant difference in empathy, gratitude and helping behavior. Secondly, variables influencing helping behavior were found to differ by developmental stage. The variable influencing the helping behavior of elementary school students was found to be empathic concern. For middle school students, guilt was found to influence their helping behavior, while for high school students, perspective-taking was found to be the key variable. Thirdly, gratitude was found to have a partial mediating effect on the relation between empathy(or guilt) and helping behavior.

The study was conducted to compare organizational innovation depending on the leadership type of middle managers in general hospital. Moreover, the study was also to prove whether employees'readiness causes any differences to the link between leadership and organizational innovation. The result is based on 769 sheets of survey paper answered by administrations and nurses working at general hospitals or the same level of hospitals located in the metropolitan area. The methods of analysis used are as follows: reliability analysis, frequency analysis, t-test, ANOVA, multiple regression analysis, and hierarchical regression analysis. Main results of the study can be summarized as below. First, by analyzing the influence of task-behavior leadership on organizational innovation, R squre on knowledge management which is organizational innovation factor was 12.5%, R squre on creativity was 9.1%, and R squre on innovation behavior was 10.3%. Regression model appeared to be statistically significant as well. Both task-behavior and relationship-behavior leadership have influence on organizational innovation and it is learned that relationship-behavior leadership has a bigger influence on all the organizational innovation factors. Second, moderating effect of the employee's readiness is examined in terms of the link between leadership and organizational innovation. As a result, the member's readiness had positive influence when it comes to the link between leadership and organizational innovation. Also, after verifying moderating effect of readiness (ability/willingness), this study shows that ability readiness has positive influence on the link between task-behavior(or relationship-behavior) leadership and creativity, and innovation behavior while willingness readiness positively influences the link between task-behavior(or relationship-behavior) leadership and creativity & innovation behavior. To summarize results of the study, this study shows that the members who possess high readiness also have high organizational innovation, which promises their positive role in a group.

Peroxiredoxin 6 (PRDX6) is a bifunctional protein with both glutathione peroxidase and calcium-independent phospholipase activity. Recently, we reported that PRDX6 plays an important role in dopaminergic neurodegeneration in Parkinson's disease. However, the relationship between PRDX6 function and emotional behavior remains elusive. In the present study, we examined depression- and anxiety-like behaviors in PRDX6-overexpressing transgenic (PRDX6-Tg) mice using the forced swim test, tail suspension test, open field paradigm, and elevated plus-maze. PRDX6-Tg mice exhibited depression-like behaviors and low anxiety. In particular, female PRDX6-Tg mice exhibited anxiolytic behavior in the open field test. Furthermore, the serotonin content in the cortex and 5-hydroxytryptophan-induced head twitch response were both reduced in PRDX6-Tg mice. Interestingly, levels of dopa decarboxylase expression in the cortex were decreased in male PRDX6-Tg mice but not in female mice. Our findings provide novel insights into the role of PRDX6 in 5-HT synthesis and suggest that PRDX6 overexpression can induce depression-like behaviors via downregulation of the serotonergic neuronal system.

This paper presents the results of a numerical investigation of the effect of geotextile reinforcement on underlying buried pipe behavior using PLAXIS 3D. In this study, variable parameters such as the in-plane stiffness of the geotextile, the pipe stiffness, the soil stiffness, the footing width, the geotextile width, and the location of the geotextile reinforcement layer are investigated. Deflections and bending moments acting on the pipe are evaluated for different combinations of variables and are presented graphically. It is observed that with an increase in the in-plane stiffness of the geotextile reinforcement, there is a tendency for a decrease in both deflections in the pipe and bending moments acting on the pipe. Conversely, with an increase in the pipe stiffness, geotextile reinforcement efficiency decreases. In the investigated region of soil stiffness, for the given pipe and geotextile stiffness, an optimum efficiency of geotextile is observed in medium dense soils. Further, it is shown that relative lengths of geotextile and footing has an important role on geotextile efficiency. Lastly, it is also demonstrated that relative location of geotextile layer with respect to the buried pipe plays an important role on the geotextile efficiency in reducing the bending moments acting on the pipe and deflections in the pipe. In general, geotextiles are more efficient in reducing the bending moments as opposed to reducing deflections of the pipe. Numerical validation is done with an experimental study from the literature to observe the applicability of the numerical model used.

Elderly population of Korea has been significantly increasing, therefore, social and economical influence of the elderly people has been increasing, too. Recently, research regarding elderly people is important because many elderly men take care of their appearance and clothing, and clothing plays an important role in everyday life. The purpose of this study is to investigate the clothing behavior of men aged 55 years and older who were residents of Seoul. The data were collected with a interview and self-administered questionnaire at various places. The importance of various factors on clothing behavior is different. 2. Age has a negative relationship with conformity, but a positive relationship with aesthetics and satisfaction of clothing. Allowance has a positive relationship with all clothing behaviors factors excepts conformity. 3. Life satisfaction has a positive relationship with education and allowance, also, life satisfaction of occupation group is higher than no occupation group is higher than no occupation group. 4. Appearance satisfaction has not a significant relationships with age, but, has a positive relationship with education. 5. There are positive relationships between not only life satisfaction and clothing behavior factors, but also appearance satisfaction and clothing behavior factors except conformity.

So many patterns of the clothing give the specific indication for one's clothing behavior and present the common style for the society. Human being gives the one's free expression and attempts to change the existing cultural environment by the clothing even though human being would be restricted in choosing the clothing within the category of the society & the culture. The value of human being which attempts to escape the restriction through the behavior theory of T. Parsons is analysed and studied. The role of the modern society is being transformed and human being attempts to express one's self through the clothing very strongly. The clothing behavior means the expression of oneself for others. This phenomenon comes from the changing of human being's view of value through the social & cultural environment which give human being the freedom of the individual to choose the various clothing.

Crowd behavior analysis research has revealed a central role in helping people to find safety hazards or crime optimistic forecast. Thus, it is significant in the future video surveillance systems. Recently, the growing demand for safety monitoring has changed the awareness of video surveillance studies from analysis of individuals behavior to group behavior. Group detection is the process before crowd behavior analysis, which separates scene of individuals in a crowd into respective groups by understanding their complex relations. Most existing studies on group detection are scene-specific. Crowds with various densities, structures, and occlusion of each other are the challenges for group detection in diverse crowded scenes. Therefore, we propose a group detection approach called Collective Interaction Filtering to discover people motion interaction from trajectories. This approach is able to deduce people interaction with the Expectation-Maximization algorithm. The Collective Interaction Filtering approach accurately identifies groups by clustering trajectories in crowds with various densities, structures and occlusion of each other. It also tackles grouping consistency between frames. Experiments on the CUHK Crowd Dataset demonstrate that approach used in this study achieves better than previous methods which leads to latest results.

While green packaging related concerns are mainly studied in developed countries, there is a lack of knowledge to observe purchase behavior toward green packaging in developing countries, especially in Vietnam. Buying green packaged products in FMCG is not required to trade-off between sustainability and product performance. Hence, this present research aims to understand the gap attitude - behavior existing on FMCG green packaged products among Vietnamese young consumers with psychosocial factors (environmental concern, environmental knowledge of green packaging and green trust) and contextual factors (availability of desired green packaging and product attributes). With a sample size of 396 respondents, data was collected by convenient sampling method and then was analyzed using structural equation modeling. The results reveal that all psychosocial factors are positive related to attitudes while purchase behavior is positively influenced. The findings also report that contextual factors have positive impacts on purchase behavior, which proves the important role of contextual factors in influencing consumer choices. It suggests that green packaging is receptive to Vietnamese young consumers but it should be considered within product-related context to enhance the difference in sustainability among similar FMCG products. Practical implications for marketers and future researches have also been discussed at the end of study.

An experimental study has been carried out of the combustion behavior of single fuel droplets of water-in-light oil emulsions in an electric furnace to elucidate the dominant factor for the occurrence of micro-explosions. The tests were carried out by changing the following four parameters; the size of water droplets in the emulsified fuels having the same water content, the ratio of water to light oil, ambient temperature in electric furnace, and the kind of fuel having different viscosity(Kerosene, Olive Oil). The result shows that the each parameter plays the different role in the effect on behavior of vaporization, explosion, ignition and combustion for single droplets of water-in-oil Emulsified fuels.

This study is purposed to make sure of the Effects of Enterprise Trust on Relation-Continuing Intention and the Mediation Effects of Relation-Continuing Intention in the effects of Enterprise Trust on Customer Citizenship Behavior. Enterprise Trust consists of two elements(Enterprise Sincerity, Enterprise Ability), Customer Citizenship Behavior is made up of two elements(Guest Preference, Guest Cooperation) and Relation-Continuing Intention has one element itself. As a result, two things have been found. First, Enterprise Trust has a partly positive impact on Customer Citizenship Behavior. In details, both of two elements of Enterprise Trust have positive influences on Guest Preference, one element of Customer Citizenship Behavior, on the other hand, Enterprise Sincerity, one element of Enterprise Trust has a positive influence on Guest Preference, one element of Customer Citizenship Behavior but Enterprise Ability, the other element of Enterprise Trust, has no meaningful impact on Guest Preference. Second, Relation-Continuing Intention has a mediating effect between Enterprise Trust and Customer Citizenship Behavior. In details, Relation-Continuing Intention has a partial mediating role between Enterprise Sincerity and Guest Preference, between Enterprise Ability and Guest Preference and between Enterprise Sincerity and Guest Cooperation. However Relation-Continuing Intention has a full mediating role between Enterprise Ability and Guest Cooperation.
