In this study, we examined the effect of shared leadership on organizational trust, knowledge sharing, and innovative behavior. Also, it was verified that organizational trust and knowledge sharing play a mediating role in the relationship between shared leadership and innovative behavior. Data were collected from a survey of 348 manufacturing workers in Ulsan and Gyeongju. SPSS 22 was used for frequency analysis and exploratory factor analysis. AMOS 22 was used for confirmatory factor analysis to verify the validity of the variables and for covariance structure analysis to verify the research hypothesis. The results of this study are as follows. First, shared leadership has a significant positive effect on organizational trust, knowledge sharing, innovative behavior. Second, organizational trust has a significant positive effect on knowledge sharing and innovative behavior. Third, knowledge sharing has a significant positive effect on innovative behavior. Finally, organizational trust and knowledge sharing play a partial mediating role in the relationship between shared leadership and innovative behavior. The result of this study suggests that organizational trust and knowledge sharing should be strengthened through shared leadership in order to increase the innovative behavior of organization members.

This study conducted a regression analysis on 312 local government officials in Gyeonggi-do to verify the hypothesis on the relationship between job autonomy and organizational citizenship behavior. Path analysis was conducted to analyze the mediating effect of organizational fairness recognition and the moderating effect of self-efficacy. Looking at the analysis results, first, it was confirmed that the higher the degree of job autonomy perceived by the members of the organization, the more positive (+) organizational citizenship behavior was. Second, the partial mediating effect of procedural justice was confirmed in the relationship between autonomy and organizational citizenship behavior. On the other hand, the mediating effect of distributional justice was rejected in the relationship between autonomy and organizational citizenship behavior. Third, self-efficacy controlled the mediating role between job autonomy and organizational citizenship behavior in recognition of procedural justice. Fourth, it was analyzed that self-efficacy plays a controlling role between job autonomy and organizational citizenship behavior. The results of this study are expected to contribute to the development of organizational behavior theory through preceding factors of organizational citizenship behavior to improve the organizational performance of local public officials.

This study examines factors that influence delinquent behavior among Korean adolescents using longitudinal analysis. A total of 1,012 students completed a questionnaire when they were Grade 6 and 739 students completed a follow-up questionnaire when they became Grade 9. Results of multiple regression analysis indicate that the following variables predicted delinquent behavior of Grade 9 students: Bullying, previous delinquency, experience of punishment, victimization, social efficacy, and moral disengagement. The above six variables have direct and mediating influence of delinquent behavior. Relational factors also influenced delinquent behavior. Social exclusion from friends reduce social efficacy, which increases victimization and which in turn increases bullying, leading to greater delinquency. Parental rejection, social exclusion from friends and hostility from teachers increase moral disengagement, which increases bullying, leading to delinquency. Low academic achievement increases the likelihood of being punished, which increases bullying, leading to delinquency. The results indicate that moral disengagement and social efficacy are mediating factors of delinquency and negative life-events (i.e., social exclusion from friends, rejection from teachers, hostility from parents and low academic achievement) increase the likelihood that Korean adolescents will engage in delinquent behavior. Implications of the results for future research are discussed.

This study aimed to investigate how teacher's attitude toward violence affect students who experienced bullying victim in their role in making peer-to-peer violence deepen, and how students who experienced the bullying victim react to show aggression, and the aggression is blocked by teacher's attitude toward violence, resulting in decrease of doing the bystander's negative behavior. By conducing this study, this study ultimately aimed to ensure that the teacher's attitude toward violence is very important in preventing peer bullying in the classroom. To achieve this aims, this study conducted a survey of 820 fourth, fifth and sixth graders in 40 classes at 10 elementary schools and limited only 365 of the respondents who reported experiencing peer bullying victim. This study utilized the structural equation modeling method to analyze the data. The results were as follows. First, it showed that the lower the bystander's negative behavior in victims who experienced peer bullying, and the lower the responsive aggression reacted from the peer bullying, when the teacher shows an unacceptable attitude toward violence. Teacher's attitude toward violence also appears to affect peer bystander's negative behavior by mediating peer bullying victim's reactive aggression, indicating that the teacher's attitude toward classroom violence may reduce the aggression of students from the experience of victimization, and consequently prevent the classroom from becoming more leprosy by reducing peer bullying.

The present empirical research examines the effect of team leader's ethical leadership on team members' in-role behavior and psychological capital. This study also predicts that management decoupling and personal decoupling will moderate the effect of ethical leadership negatively. A growing body on leadership research highlights the role of team leader's moral manager in team settings. Ethical leadership also becomes a salient issue in the situation of unethical decision making and misuse of management power which have done by unethical leaders all around the world. In order to identify the effect of ethical leadership, I collected data of 922 team members from bank, semiconductor manufacturer, and university hospital. Our findings show that ethical leaderships have a positive effect on team members' in-role behavior and psychological capital. In addition, I also found the significant moderation effect of management decoupling which team members perceive their top management team's inauthenticity. Contrary to the prediction, however, the result doesn't support the moderation effect of personal decoupling. I discussed implications of confirming and disconfirming findings in details.

This paper investigates the relationships between leader-member exchange(LMX), perceived team efficacy, and organizational citizenship behavior(OCBI, OCBO) in the Korea Post. Also the study investigates the moderator effect of leader integrity and the mediator effect of perceived team efficacy in the relationships between LMX and OCB(OCBI, OCBO). The multiple regression analysis were employed to test the hypotheses. The main finding of this study was as follows: First, LMX had a positive effect on the perceived team efficacy. Second, the perceived team efficacy had a positive impact on OCB(OCBI, OCBO). Third, the perceived team efficacy completely mediated effect on the relationship between LMX and OCBI. Also the perceived team efficacy partially mediated effect on the relationship between LMX and OCBO. Fourth, the positive relationships between LMX and OCB(OCBI, OCBO) were stronger when leader integrity was high rather than low. In particular, this review concludes with implications for future research, limitations of this study, and practical application.

This study investigated South Korean citizens' political communication and deliberation through Twitter during the 2014 General Election, focusing on influential opinion leaders' political information behaviors. Individual semi-structured interviews were administered with 13 opinion leaders using the multiple interview modes of email interviews, Skype interview and face to face interviews. Through the analytical lens of the theory of Information Worlds, the chosen social types and social norms of opinion leaders impacted their political information behaviors, including how they assessed, shared, exchanged, or avoided information, and, in turn, created boundaries between and around their information worlds that allowed for both conflict and synergy.
