The purpose of this study was to explore the effects of work rewards on the organizational effectiveness including mediator role of self-efficacy, and also the work rewards was divided into three categories of task rewards, organizational rewards and social rewards, organizational effectiveness into two categories of organizational commitment and job satisfaction. Research findings are follows; First, job diversity and job challenge of task rewards, payment of organizational rewards, superior support of social rewards have a positive influence on organizational commitment. Second, job diversity, job challenge and job autonomy of task rewards, superior support of social rewards have a positive influence on job satisfaction of finance public enterprise employees. Third, tested mediator role of selt-efficacy between work rewards and organizational effectiveness, and found out moderating roles between work rewards and organizational commitment, but its role between organizational rewards and job satisfaction was found only in job stability of organizational rewards. In terms of the results of this study, the theoretical and practical implications of the findings were discussed and directions for future research were presented.

The purpose of this study is to investigate the causal relationships among self-efficacy, perceived usefulness, supervisor and peer support, satisfaction, and transfer intentions in the corporate mobile learning. For this study, the web survey was administered to 302 mobile learning learners of the A domestic corporation in South Korea. Structural equation modeling(SEM) analysis was conducted in order to examine the causal relationships among the variables. The results indicated that first, self-efficacy, perceived usefulness, and supervisor and peer support had positive effects on satisfaction. Second, supervisor and peer support and satisfaction had positive effects on transfer intentions. Third, satisfaction mediated the relationship between self-efficacy and perceived usefulness, while it did partially the relationship between supervisor and peer support and transfer intentions. Based on the result of the research, the study proposes organizational environment with cooperative supervisor and peer support should be made in order to improve the level of learners' transfer intentions. In addition, learning strategies that facilitate learners' self-efficacy and mobile information technology acceptance are needed to develop for enhancing the learners' satisfaction.

This research attempts to analyze the relationship among leadership, LMX and organizational achievements for chefs in the Jeju district. The results of the research revealed that the leadership type only affected the servant leadership of LMX. Furthermore, the job satisfaction for leadership and LMX was influenced by organizational commitment. Therefore, to strengthen the relationship of LMX, the leadership type's servant leadership must be the essential link between the relationship of LMX, and LMX serves as the link between leadership and organizational achievement. Ultimately, to augment the employer-employee relationship, the factors of servant leadership must be applied, for example, by taking good care of the workers, persuasion, attentively listening to the workers, sympathy, and suggestion of vision, as well as the mutual link and respect among the employers and employees, all of which were shown to have positive influences on the organizational achievements.

This paper attempted to empirically analyze whether or not ethical behavior at the individual level has a positive effect on both companies and employees. In addition, based on the social exchange theory, a hypothesis was established that perceived supervisory support has a positive moderating effect on the relationship between ethical behavior, job satisfaction, and job performance. As a result of analyzing a questionnaire given to 238 sales employees, It was first verified that ethical behavior by sales staff had a positive effect on job satisfaction and performance, as expected in the hypothesis. Second, the moderating effect of perceived supervisory support was significant only in the relationship between the ethical behavior of the salesperson and job performance. On the other hand, the moderating effect of perceived supervisory support on the relationship between ethical behavior and job satisfaction was not verified. Based on the results of this study, the implications and future directions of study are presented.

This study tested the relationship between servant leadership and intrinsic motivation. And, the mediating role of intrinsic motivation between servant leadership and individual performance was also investigated. Based on related theory and literature review, 4 hypotheses were developed and tested. Questionnaires were distributed to 280 employees of 3 service enterprises. Among returned questionnaires, 214 samples were used for empirical study. According to results, listening behavior of supervisor had significant positive effects on intrinsic motivation of subordinate. But, sympathy behavior and service behavior of supervisor had no significant effects on intrinsic motivation of subordinate. Also, intrinsic motivation of subordinate had significant positive effects on job satisfaction and organization commitment. Finally, the results suggest that intrinsic motivation mediate the relationship between servant leadership and individual performance. The mediating role of intrinsic motivation between servant leadership and individual performance was partly or fully supported. Implications and directions for future research are discussed in conclusion.

The OCB(organizational citizenship behavior), spontaneous extra-role behavior of social workers, plays very important role in the provision of qualitative service for the clients and the organizational performance of social welfare agencies. Starting from the importance of OCB for the effective organizational management, this study focuses on the effects of antecedents such as organizational justice(procedural and distributional) and trust in supervisor on the OCB. This study collected data from 360 social workers and 59 their supervisors working in the community welfare centers, paired the self-reported data and the supervisor-rated data, and analyzed the data through the SEM (Structural Equation Modeling) method. The findings of the study show that organizational justice(procedural and distributional) has no direct effect on the OCB, but indirect effect on the OCB through the mediator of trust in supervisor, and that procedural justice has more effect than distributional justice. This study suggests that the management of spontaneous behavior of social workers is not a separated fragmentary phenomenon but should be understood and managed comprehensively in the continuation of the perception of organizational members for the organizational management, the resulting affectivity toward their supervisor, and their behavior in the organizational life.

The purpose of this study was to investigate the correlation between visual analogue scale(VAS) of the waist and Oswestry Disability Index(ODI) and the muscle strength of the waist for male field hockey athletes. The VAS and ODI were conducted by self-written evaluation, and muscle strength was measured by using DAVID. Pearson correlation was used for data analysis, and the statistical significance level was set to α = .05. The VAS of the waist of male field hockey athletes and the ODI were statistically significant. However, other VAS and the ODI did not correlate to the strength of the lower back. Therefore, there is a need to develop a new exercise program for the rather than strength training during the waist rehabilitation exercise. It is thought that these studies will serve as basic data useful for the development of treatment and exercise programs for athletes in the future.

The performance of supersonic impulse turbine was investigated experimentally. Experiment was performed with the compressed air instead of the high temperature burned gas because of the limitation of test facility and danger. As a result of the experiment with the compressed air, the performance in the real gas(burned gas) was predicted by the similarity method. The nozzle area of prototype turbine was calculated based on the real gas. So, it is difficult to satisfy the similarity conditions completely. Two similarity conditions were set and the design point for real gas was existed between two similarity conditions. And, the new turbine test model with calculated nozzle area based on the compressed air was tested. Therefore, similarity point of the new turbine test model was also existed between above two similarity points. It means that the design point for real gas was similar to the test point with the new turbine model.
