This research was to investigate and study on 92 Dental Technicians who had had some experience of working or being employed at dental craft-shops or craft-rooms in Seoul area and had transferred to other types of occupation, with regard to their reasons for changing their profession. For an approach to the study, some questionnaires and interview including 3 aspects of in quiriesmental, economic and social backgrounds-were administered, and major findings are as follows ; 1. The ages in which transferring to other kinds of job happened occurred mostly from 20 to 30(78.26%) an a group of subjects whose ages ranged from 20 to 30 years old. And, with regard to their experience of working or being employed at dental craft-shops or craftrooms, the transfer of their profession to the other kinds mosty happened in a group of subjects(94.56%) whose experience of working in the dental field is less than 4 years. 2. The reason of transfer with reference to the mental background was mostly mattered in a group that expressed "Excessive Work Duties"(34.78%), and most lowly mattered in a group of subjets who had "Certain Relations with Dentists"(8.70%). Thus, it appeared that the biggest reason of transfer by the mental background was, due to the excessive duty work, not to have Sufficient time to be usualized by dental technicians for their own purpose. 3. With reference to the economical background, a group that declared there was "No Wage Standards in Ratio to Their Labor" was the most in the separation rate as shown 45.56%. And, a group suspecting "No Guarantee for Their Living after Retirement" Showed a separation rate, 9.78%. In other words, the reason for transfer was that they did not receive due wage according to their amount of labor. 4. With reference to the social background, a group making a subject for no good working environments or conditions had a separation rate, 41.30%, which was the most among others, and a group with a subject of "The Rarity of Employment because of Excessive Supply of Dental Technicians" had the rate, 10.87%, which was the lowest. This meant that the major cause of transfer by the social background was a phenomenon for dental technicans to escape from unclean working places.

In previous research of social dilemma, there is no extended game that the players can select one game out of some social dilemma games. We propose this kind of game as ＂Distributed Social Dilemma＂ In this game, each player tries to acquire the adaptive strategy throughout local interactions. We make use of GA as evolutionary operations. In this paper, our purpose is to examine how the game selection of players influences the evolution of cooperation in distributed social dilemma. In order to examine, we formulate distributed social dilemma by Game Theory and use agent-based simulation that each agent is regard as player

Social commerce is a new type of e-commence that is based on social networking technologies and aggressive marketing strategies, such as one-deal-a-day. However, although social commerce has become very popular, little is known of customers' substantive purchasing behaviors when using social commerce sites. These behaviors, namely visiting and purchasing behaviors, are the focus of this study. Hence, this study aims to provide comprehensive understanding of the visiting and purchasing behaviors of customers in relation to social commerce sites. A research model based on the utilitarian and hedonic values of shopping, social influence, and convenience, which represent social commerce features, was developed and empirically analyzed using data from social commerce site users. The results revealed that purchasing behaviors of consumers when they use social commerce sites are affected directly by the utilitarian value (perceived usefulness) of the site as well as their purchase intention. Purchase intention is affected by perceived usefulness, subjective norm, and visiting behaviors. The visiting behaviors of consumers in relation to social commerce sites are also affected directly by the hedonic value (playfulness) of the site as well as their intention to visit the site. The findings of this study have implications for practitioners with regard to understanding and promoting the use of social commerce sites.

In general, grandparents have been very influential resource persons on their grandchildren's gross development. Nevertheless it has been difficult to find many empirical studies that focused on the specific competence of grandchildren and showed strong evidence in its regard. Therefore this study was intented to investigate the influence of grandparents' social support on their grandchildren's social competence in the light of grandparent's social support on their grandchildren's social competence in the light of grandchildren-grandparent relationship. The subjects were 230 fifth grade children in elementary school who were 123 boys and 107 girls. Among them, 94 children were related with grandfathers, 167 children with grandmothers 101 children with maternal grandfathers and 182 children with maternal grandmothers. The questionaire was used as a methodological instrument and the statistics such as frequency, percentile, mean, Pearson's correlation, One-Way ANOVA and Scheff test were used for data analysis. The findings were as follows : 1) Children's affectional intimacy to grandparent was positively correlated with perceived grandparent's social support. 2) Perceived grandparent's social support was affirmatively correlated with grandparent-mother relationship, that is, grandchildren-grandparent relationship was mediated by mother. And 3) children who more perceived grandparent's social support than less perceived grandparent's social support were highly rated I social competence by teacher. In the result, children emotionally, informatively and instrumentally supported by paternal or maternal grandparents showed high social competence defined supported by paternal or maternal grandparents showed high social competence defined as interpersonal relationship ability on the significant level respectively.

It is a recent trend to emphasize community services for the rehabilitation of the mentally ill. However, it is also necessary to provide social work services for those living in the institutions, who is the most underprivileged in our society. To deal with interpersonal skill deficits which is one of the main characteristics of the mentally ill, social skills programs are being utilized, usually in the communities, but not in the institutions. Therefore, the objective of this study is to develop and evaluate institution-relevant program for the improvement of assertiveness, which is the basic ability among the interpersonal skills, and self-esteem, which is the emotional basis of assertiveness. Because there has been little literature on such a program, a preliminary program had been implemented in order to include the peculiarities of the life in the institutions on the main program. The evaluation of the program effect was done by pretest-post test control group design, and its results are as follows. Firstly, in regard to program effectiveness, the pre and post test showed that self-esteem improved in a statistically meaningful way, but that assertiveness did not so. However, the staff verified the improvement of the group members' assertiveness to some degree in their actual lives. Secondly, in regard to the group process, the group interaction improved in a statistically meaningful way between 2nd and 5th session, and the improvement maintained till the program termination. Also the group members evaluated the program as helpful in their everyday lives. Therefore it can be said that the result of this program is encouraging. In light of this, several suggestions were made: utilizing more dynamic techniques in the program; developing the advanced level of the program; making an effort to change environmental structures as well as individuals; applying this kind of program to another living facilities such as those for the homeless or handicapped.

The result of this study suggests that students' perception of service value is related to functional value with regard to need and satisfaction, epistemic value, image, emotional value, functional value with regard to price and quality, and social value. Specifically female students give less importance to epistemic value than their male counterparts. Students in the 2nd grade gave less favorable scores to the functional value with regard to need and satisfaction, epistemic value, image, emotional value and functional value with regard to price and quality than students in the 1st grade. Students in the night class gave less scores to epistemic value and functional value with regard to price and quality than students in the day class. It is confirmed that the difference between groups by the period in school is in functional value with regard to need and satisfaction, image, emotional value, and functional value with regard to price and quality. And it is also revealed that these results are similar to the results of analysis by the grade. In conclusion college operators should not overemphasize that the department of Hotel culinary arts occupies the leading position of the culinary academic world in Korea and the firms of food service industry positively evaluate the department of Hotel culinary arts, and in order to cope with the rapidly changing environment of the culinary education consistent investment constant changes and of efforts should not be stopped. On one hand the teaching staff of the department of Hotel culinary arts should reconsider their original role, and need behavior and practice to fill their deficiency with steady efforts in terms of students' perceived service value. In addition the students of the department of Hotel culinary arts should not be shackled by the past tradition, should not take a pessimistic view of the present situation, should not take an optimistic view of the future, and should always cultivate their ability to provide for the future.

Objectives In regard to the social competition hypothesis, depression is viewed as an involuntary defeat strategy. A previous study has demonstrated that adaptation in microenvironments can result in a wide range of behavioural patterns including defense activation disorders. Using a simulation model with evolutionary ecological agents, we explore how the fitness of various defence activation traits has changed over time in different environments with high and low social mobility. Methods The Evolutionary Ecological Model of Defence Activation Disorder, which is based on the Marginal Value Theorem, was used to examine changes in relative fitness for individuals with defensive activation disorders after adjusting for social mobility. Results Our study examined the effects of social mobility on fitness by varying the d-values, a measure of depression in the model. With a decline in social mobility, the level of fitness of individuals with high levels of defense activation decreased. We gained insight into the evolutionary influence of varying levels of social mobility on individuals' degrees of depression. In the context of a highly stratified society, the results support a mismatch hypothesis which states that high levels of defence are detrimental. Conclusions Despite the fact that niche specialization in habitats composed of multiple microenvironments can result in diverse levels of defensive activation being evolutionary strategies for stability, decreased social mobility may lead to a decrease in fitness of individuals with highly activated defence modules. There may be a reason behind the epidemic of depression in modern society.

Through analyzing papers on digital libraries and the contexts of usage of the term, ‘digital library’, this study investigates that the professional discourses about digital libraries regard them digital technologies. But digital libraries need to be recognized as socio-technical networks which are constructed by social interaction between heterogeneous elements. The study suggested that Social Informatics and a STIN(Socio-Technical Interaction Network) model should be applied to understand and analyze digital libraries as socio-technical networks.
