Furthermore the study has its aims at advancing instructors' skills by using finding of it. The study used 'SPSS 11.0 FOR WINDOW - Statistical Package' to analyze the collected samples and dealt with data of 174 individuals. Statistical analysis of the research for hypothesis verification was about frequency, trust level, mutual relationship, variables, and T-verification. The meaningful level for any result was ranged within 95%(p< .05), 99%(p<.01). The finding are as follows. Effects on pleasure, one of elements of team spirits taken by instructor's training style are analyzed as follows. It was proved to be meaningful in relation with a series of activities like training, democratic, social, compensatory aspects and showed also considerable relation with power based behaviors. That says, players are found to enjoy high pleasure when social and bureaucratic behaviors of instructors are very energetic. In addition to that, training, democratic, and compensatory activities didn't show any meaningful effect. Team spirit was found to play a main role between instructor's behaviors and training, democratic, social rewarding activities. Democratic and social acts influence on team spirit. Looking into the detailed aspects, team spirit was resulted very high in the individuals with low democratic mind and was shown high group spirit by groups with high sociable activities.

This study examines the effect of founders' strategic orientation and social capital on the performance of startups in Korean contexts. Founders' strategic orientation is proposed as the main factor to reduce the risk of failure and to increase the potential of future growth of the startup. Three main components of strategic orientation, entrepreneurial, market, technology, were simultaneously tested with a sample of Korean startups. Furthermore, founders' social capital, networks with supporting entities and the level of chemistry within founding members were also proposed to be important factors. We also tested possible mediating effects of social capital on the main impact of strategic orientation. With a sample of 79 startups founded less than 5 years in Seoul Metropolitan Areas, we found that technology orientation of founders only significantly increases the performance of startups, but both entrepreneurial and market orientation do not. Regarding social capital effect, the external networks of the founding members are effective as proposed, and also the high cohesiveness of founding members increases the startup performance. However, the mediating role of social capital is just partially confirmed. The implications of our findings, in both sense of firm's strategy and startup policy, are discussed. This study is expected to be a bridge connecting firms' strategy with startup policy-making in Korea.

Knowledge is a key resource for organizations to gain and maintain competitive advantage. Therefore, it is important for organizations to motivate employees to share knowledge with each other in order to achieve optimal performance of knowledge resources. Despite the efforts of organizations to share knowledge, knowledge hiding is still prevalent among employees. In this paper, we want to analyze the factors that may cause more general and pervasive knowledge-hiding behavior in organizations through empirical analysis. The results of this study show that, first, the relationship between team cohesion and knowledge hiding has been verified differently depending on the sub-behavior of knowledge hiding : playing dumb, evasive hiding, and rationalized hiding. Team cohesion has been shown to significantly reduce the playing dumb and evasive hiding. On the other hand, it was shown that team cohesion did not have a significant causal relationship with rationalized hiding. Second, the moderating effect of ethical leadership has been statistically significant in terms of team cohesion and relationships with playing dumb and evasive hiding. In other words, the higher the ethical leadership, the stronger the negative relationship between team cohesion and knowledge hiding. Finally, the theoretical and practical implications of this paper and future research directions are discussed.

The purpose of this study is to verify that voting behavior of congressmen can vary depending on the different candidate selection methods of political parties. Specifically, this paper examines whether congressmen elected through a primary tend to deviate from the party line vote in the floor voting, compared to those who did not. As a result, it was founded that congressmen who went through competition of the primary are more likely to defect from the party line vote than who did not. This empirical evidence suggests that if the introduction of the open primary system is further expanded in the future, it may lead to weakening of party cohesion and reinforcing lawmakers' autonomy.

Recently, Dennis et al.(2008) proposed media synchronicity theory. In this theory, for conveyance communication processes, use of media supporting lower synchronicity should result in better communication performance. But for convergence processes, use of media supporting higher synchronicity should result in better communication performance. This paper proved a part of the propositions of media synchronicity theory, because media synchronicity theory was proposed theoretically, not empirically. We used a data set generated from the survey. The respondents of survey were 163 students who had experienced the communication media in the classes that should summit result of team projects or team reports. According to the results of data analysis, higher use of communication media led to better learning performance. The familiarity of task moderated the effect of communication media on learning performance. And use of media supporting higher synchronicity led to better learning performance.

The purpose of this study is to find specific practice methods of single parents self-help groups in community welfare centers. A participatory action research was conducted to achieve the purpose. Six social workers and three researchers participated in the study who shared the problem of lack of specific practice methods even though a self-help group was useful for self-reliance and empowerment of low-income single-parents. Various activities such as reading articles, analysis of each self-help group, case studies, and learning facilitation methods were conducted during 10 meetings. At the same time, peer supervision proceeded at each meeting. The progress of each group was shared, the application of practice methods and plans were discussed, and applying discussed methods to group practice and reviewing the process and outcomes of the practice were repeated in the peer supervison. As a result, the following positive changes appeared: First, the goals and vision of each group became clearer. Second, initiative of the members was promoted. Third, intimacy, mutual cooperation, the attatchment to the group were strengthened. A qualitative analysis was also conducted on the content discussed. As a result, 17 practice methods were derived in four themes such as initiative/ empowerment, cohesion, leadership, and destandardization. Practice issues concerning single parents self-help groups in community welfare centers were discussed based on the results.
