As aging society makes rapid progress, various social problems arise. The drop of productive labor and the increase of welfare cost can be taken as examples. From this point of view, a use of aged labor is a matter of great Important to national productivity improvement. But, the participation rate of the aged in economical activity amounts to 49.8 percent and their unemployment rate does 2.1 percent. The purpose of this paper is to analyze the deterioration of skill and the lowering of adaption to new working environments due to aging. Since the aging effect is closely related to worker's productivity, it should be properly measured and analyzed. The coordination tester is used to find out activity limitations. Experimental results show that the expert skill of the workers can be improved through the effective of their experience. Therefore we can say that some operation is not influenced by aging.

Research on social hierarchy is a growing research topic in the studies of management and organization. Despite the abundance of studies demonstrating the relevance of social hierarchy in teams, little understanding exists for status disagreement among team members, specifically how status disagreement reduces team members' contributions to influence team performance. This conceptual study argues that team status disagreement negatively impacts team performance through reduced team member's knowledge contribution, including reduced team knowledge sharing and increased knowledge hiding. In addition, we propose that team skill differentiation aggravates the negative effect of status disagreement, such that when team skill differentiation is high, teams under high status disagreement are more likely to experience detracted team performance. This research mainly discusses status disagreement and its effect on team knowledge contributions by reviewing previous literature and developing several propositions, suggests theoretical contributions and practical implications, and presents an agenda for future research.

This study is to investigate many kinds of conceptual models of social problem solving approach as well as decision making method, and then describes educational implications, especially for more effective method of teaching problem solving ability in order to reduce children' anti social behaviors and to be able to have their healthy and happy lives. Problem solving ability or decision making skills have been taken to goal of primary school curriculum, but is too cognitive or too centered to morality for student to get that kinds of skill or competency. As a result of new education method is developed on the basis of Socal Emotional Learning(SEL) as well as Emotional Intelligence which put on the importance on the role of emotion in the problem solving. This method have two distinctions. First, It has the background of culture specific views of emotion to be proper this method in our society. Second, It should be integrated into moral education as a part of school curriculum to establish secure and long term intervention.

This study explored the relationship between peer support, strategies used to cope with interpersonal stressors, and social skills among 4th and 5th graders. Instruments were the Social Support Appraisal Scale, the Self-Report Coping Scale, and the Teenage Inventory of Social Skills. Results showed that children used different coping strategies by the level of peer support. Children with more peer support were more active in seeking social support and in solving peer conflict. Children with more problems in peer relationships used more avoidance strategies such as internalization and externalization. Children with a high level of social skills were more likely to use approach strategies in peer conflict while children with a low level of social skills were more likely to employ avoidance strategies. Internalization was the most important strategy in explaining inappropriate peer relationships. For girls, social skill was the most essential variable in their peer relationships.

This article studied the motivational factor of participation skill competition and their effectiveness. This study was restricted to cooks within those who had participated in a cooking contest to allow measurement of participation and satisfaction. This thesis investigated 116 cooks by questionnaires from April 6, 2005 to April 23, 2005, of which 106 responses were used for statistical processing to perform this study First, from the motive of participation, 13 variables were analyzed into 3 factors such as the factor of social recognition, the factor of speciality, and the factor of self-development and self-realization. The factor as a motive of participating in skill competition has a significant effect on effectiveness. A total of three factors were extracted from Recognition consisting of 10 variables. Each factor was labeled as awareness of the competition, revision of test questions, and selection of the judges of the competition. Second, three factors were derived from 12 variables in association with the effect of the contest, including factors of contribution to industry development, technical and technological effect, and psychological effect. In addition, it was revealed that the motive of participating in skill competition had an significant impact on recognition. Third, the results of regression analysis demonstrated that factors relating to recognition of skill competition and participation motives significantly influence on the effect of the contest. One limitation of this study is that the Population of the survey was limited to those who had Participated in the contest. Thus, the findings of this study may not be generalizable for other cases. It is clear that further research is needed to collect more in-dept data from other similar competitions in an effort to extend the application of the present results to other studies.

Objectives: The objective of this study is to evaluate the job characteristics of container terminal workers by applying the Job Strain model, and to assess the relationship among the general characteristics, job characteristics and psychosocial distress. Methods: A self-administrated questionnaire survey was performed to the container terminal workers in Pusan. Among the 200 male workers who answered the questionnaires, white-collar workers and blue-collar workers were 100, respectively. Karaseks Job Content Questionnaire was utilized to evaluate the job characteristics and Psychosocial well-being index (PWI) was applied to measure the extent of their psychosocial stress. Results: In white-collar workers, the skill discretion, created skill, decision-making authority, decision-making latitude, psychological job demand, and supervisor support of the job characteristics were significantly high, while in blue-collar workers physical exertion was significantly high. The result of Psychosocial well-being index (PWI) reveals that blue-collar workers were more stressed than white-collar workers, especially, the indices of depression (factor 2), sleeping disturbance and anxiety (factor 3), General well-being and vitality (factor 4) were significantly increased; whereas, in white-collar workers, only the index of social performance and self-confidence (factor 1) was significantly increased. And PWI scores were significantly increased in the lower social support and psychological job demand. By the multiple logistic regression analysis for PWI, blue-collar workers had increased odds ratio of 2.66(95% CI;1.11-6.41) compared with white-collar workers. The unmarried workers increased odds ratio of 3.54(95% CI;1.18-10.62) compared with married workers. And workers who have not own house increased odds ratio of 2.35(95% CI;1.15-4.79) compared with workers who have own house. Particularly, odds ratio of work-shift in blue-collar workers was 11.10(2.14-57.64). Conclusion: Skill discretion, created skill, decision-making authority, decision-making latitude, psychological job demand, and supervisor support were increased in white-collar workers. Decreased skill discretion and increased physical exertion were found in blue-collar workers, which is supported the Job Strain model. Job stress of blue-collar workers was comparatively higher than that of white-collar workers, especially, skill discretion, decision-making authority, decision-making latitude, job insecurity, physical exertion were noticeable factors. Especially, sleeping, smoking, and work shifting turned out to be a main cause that increases stress. Therefore, in order to decrease the job stress, a health promotion program to change the health behaviors should be activated and an organized job stress management program should be introduced. Especially, working condition for blue-collar such as physical exertion and work-shift should be improved.
