This study investigated the factors that facilitate knowledge creation of team with the aspect of knowledge management. We considered two characteristics which are team members' psychological characteristics (achievement needs and conflict emotion) and knowledge network characteristics among team members (internal cohesion and external bridging) and verified the relationship between these characteristics and team performance. Furthermore, we examined whether these characteristics have a different effect on team performance according to the mastery climate. This study performed a survey targeting team members in knowledge based firms and 376 final surveys to be used as a sample in this study. The result showed that team members' psychological characteristics and knowledge network characteristics among Team members have an influence on team performance significantly. In addition, the master climate moderated the relationship between team members' psychological characteristics and team performance.

The introduction of a team system to any organization is usually to improve that organizations dynamics, by increasing the proper adaptation to rapidly changing environments, by reducing approval procedures, and by promoting power authorization. In this regard, this study was carried out in an attempt to determine (1) whether or not the introduction of a team system can be as effective in hospital organizations as it has been in business organizations, and (2) what behavior factors influence such effectiveness. For the current study, questionnaires were distributed to the employees of a university hospital in Pusan. Four hundred eighty three of them(94.7%) were retrieved and analyzed through statistical processes. The three types of variables that were found to influence team effectiveness were: (1) independent variables of team organization characteristics, such as communication, organizational atmosphere, leadership and team knowledge, (2) intervening variables of team organization characteristics. such as job autonomy, technological variety, task subjectivity, task feedback and task importance, and(3) the dependent variables of team level effectiveness, such as job satisfaction and commitment to team organization. The gathered data were processed by using the 6.12 version of the statistical program SAS(Statistical Analysis System), and the reliance coefficient of those measured variables was then evaluated as an average of 0.78. The influence of team level effectiveness was analyzed by using multiple regression analysis. These differences in effectiveness were then analyzed on the basis of related mean values, while the differences among demo-sociological characteristics were analyzed by using the dispersion analysis(ANOVA) and the t-test. The results of the study can be summarized by the following. First, regarding the relationship between team organization characteristics and team level effectiveness, all of the factors including communication, organizational atmosphere, leadership and team knowledge were found to have a significant influence on effectiveness. Second, the factors of team job characteristics, such as technological variety, task importance and job autonomy, had significant effects on job satisfaction and organizational commitment among the teams members. Team level effectiveness was generally high, while team job satisfaction was higher the teams organizational commitment. Third, regarding the demo-sociological characteristics, team level effectiveness was found to be higher among those who were older, who had more job experience, and who had a higher position. Comparing the differences among job types, the effectiveness was relatively higher in the fields of nursing and administration/management then in other fields. Further study should be done towards the setting of variables for characteristics of hospital organization, developing suitable methods of measurement, and researching individual level effectiveness.

This study aims at analyzing the relationship between team characteristic and innovation performance. The mediating effect of creative climate on the team characteristic and innovation performance is also measured. Based upon literature review, individual creative characteristics, team diversity, team cohesion, task characteristics are presented as antecedents of team characteristic. Creative climate affects the creative behavior and innovative performance. Creative climate is measured as the Team Climate Inventory (TCI) proposed by Anderson & West (1998) including goal, participative-autonomy and innovative-support. Data were collected from 186 survey responses (54 Teams) out of total 462 (69 teams) from the R&D department of a major ICT firm in Korea. Empirical results show the diversity, cohesion, job characteristic, individual creative characteristic have a positive effect on the creative climate and innovation performance. The participative-autonomy climate factor appears to mediate the relationship between team characteristic (diversity, cohesion, job and individual characteristics) and innovation performance. However, the mediating effects of goals and innovative-support factors were not significant statistically. It was confirmed that the organization can contribute to improve the team innovation performance by facilitating a autonomy and participative climate as well as fostering the team characteristic.

The effective management of knowledge has become one of the critical success factors in current organizations. In spite of the extensive use of Knowledge Management System (KMS), useful information and knowledge resources are still transmitted through personal networks among people in organizations. Thus, social network theory which focuses on social relationships in organization can be a fruitful theoretical resource for enhancing Knowledge Management (KM) performances. In this study, we investigate the effects of intra-team network characteristics (i.e., group density and degree of centralization) and external boundary spanning activities on knowledge management performances of a team. We also acknowledge that all group members do not necessarily agree on the team goal and actively disseminate useful information and knowledge. Drawing on the political perspective on KM which emphasizes the role of trust among group members, we examine the mediating effects of team trust between internal/external network characteristics and KM performances. From the data of 220 teams in financial companies in Korea, we found that: (1) group density had positive effects on KM performances (i.e., knowledge creation, sharing, and use). (2) However, centralization was not significantly associated with KM performances. (3) Team trust was found to be an important factor mediating the relationship between intra-team network characteristics, boundary spanning activities, and KM performances. Based on these results, we discuss and suggest possible implications of the findings when designing and implementing KM practices.

This study was conducted to evaluate the effectiveness of team system at university hospitals in Korea. Data were collected from administrative and medical support workers at 4 university hospitals through the self-administered questionnaires and analyzed using frequency analysis, t-test, and oneway ANOVA. The results of this study are as follows. First, teams with higher team management characteristics show higher level of quality of work life and performance effectiveness. Second, teams which consist of members with variety background and skills show higher level of quality of work life and performance effectiveness. Third, team which have the higher autonomy, technology variety, job significance, and feedback show higher team effectiveness. Fourth, team which have team leaders with higher leadership score show higher level of quality of work life and performance effectiveness. Fifth, there are differences in team effectiveness in terms of sicio- demographic variables such as average age, position, and tenure of team members, length of team system, and team size. Sixth, the job autonomy of team members and the leadership of team managers have significant effects on the quality of work life variables. Seventh, the leadership of team leaders, job autonomy of members, and individual contact between team managers and members have significant effects on the team performance variables. In conclusion, in order to increase the effectiveness of team system in university hospitals, it is required to consider the characteristics of team management, diversity of team members, the autonomy of team members, the leadership of team manager, and the socio-demographic factors of team members.

The purpose of this study is to investigate the causal relationship between job characteristics and creativity. The role of transformational leadership is also examined. To identify the relationship between core team job characteristics and transformational leadership, an empirical survey was conducted through surveys of domestic distribution companies. Among the collected questionnaires, missing and insincere responses were excluded and 636 individuals of 107 teams were used for the SPSS 18 analysis. It was found that job meaningfulness was positively related to team creativity and transformational leadership also had a significant effect. Task feedback was shown to be an important factor on the motivation to perform tasks successfully. In the case of transformational leadership, this leadership style helped individuals overcome fear by providing support, sympathy, and consideration to create novel ideas. But, its effects were different on team creativity when it interacted with core job characteristics. Departments where creativity is highly emphasized within an organization are able to design job characteristics which fit the task at hand. Moreover, transformational leadership brings about different effects on team creativity when it interacts with job characteristics. The findings of this study suggest that organizations should consider characteristics of tasks and individuals as well when conducting education and training.
