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.

To examine that effect of internet self-efficacy on flow, perceived risk, attitude, and purchase intention, It suggested hypotheses from the basis of prior studies. All of hypotheses were supported and the findings can be summarized as follows. First, internet self-efficacy had a positive effect on flow and a negative effect on perceived risk. Second, flow had a positive effect on attitude and perceived risk had a negative effect on attitude. Attitude had a positive effect on purchase intention also. In view of the result of analysis, between flow and purchase intention are mediated by and between perceived risk and purchase intention are mediated by attitude also.

This is a descriptive research study aimed to investigate the relationship between health promoting behaviors, and some factors such as family function, health perception, and self - efficacy of nursing college students and identify the factors affecting health promoting behaviors. Results showed that family function, health perception, and self - efficacy were correlated with health promoting behaviors. Regression analysis showed that family function, health perception, and self - efficacy seemed to explain 37.7% of health promoting behaviors. Thus, as family function, health perception, and self-efficacy are important factors that affect health promoting behaviors of nursing college students, it is necessary to develop a health education program considering family function, health perception, and self-efficacy to promote desirable health promoting behaviors. In the follow-up study, it is necessary to expand the study subjects and the results of such studies should be applied to the development of programs aimed at promoting the health of nursing college students, and further studies should be conducted to verify the effectiveness of those programs.

The purpose of this study is to identify the effects of perceptions of organizational politics(i.e., POPs) and leader-member exchange(i.e., LMX) on the perceived work performance. Also, this paper investigates the moderating effect of LMX on the relationship between POPs and work performance. Particularly, this study is to expand on prior research by investigating the three-way interaction effect of LMX and self-efficacy. The summary of results based on a sample of 280 employees who were working in various organizations in KOREA is following. First, POPs were not significantly related to perceived work performance. Second, LMX was positively and significantly related to perceived work performance. Third, LMX did not moderate the negative relationship between POPs and perceived work performance. Finally, our results showed that for individuals with a high level of self-efficacy, LMX moderates the negative relationship between POPs and perceived work performance. That is, for individuals with a high level of self-efficacy, POPs were positively related to work performance under high LMX(in-group), but were negatively related to work performance under low LMX(out-group). Theoretical and practical implications of our findings as well as directions for future research are provided.
