One of the organizational characteristics in the modern society is the emphasis placed upon individual autonomy in an effort to promote and develop each member's morale as well as the efficiency in personnel management. Therefore, it can be understood that the importance of "Self" is recognized in work places and the leadership of supervisors and each member's self-management and control are also emphasized, leading to establishment of the "Self-leadership" concept. In this study, the effect of the Transformational Leadership of the supervisors on the subordinates' Self-leadership was analyzed and the causal factor of organizational support in the relationship between Transformational Leadership and Self-leadership was defined. A survey was conducted with 182 security officials at the National Assembly and the following results were obtained. First, Transformational Leadership had a positive effect on Self-leadership and the Transformational Leadership of the supervisors had a statistically significant impact on the organizational support awareness. Furthermore, organizational support showed a statistically significant mediator effect in the relationship between the Transformational Leadership of the supervisors and the Self-leadership of the subordinates. Finally, future directions in regard to the personnel management system were suggested.

This study analyzes the influence of the four components of authentic leadership on employees' OCB and job performance to suggest the implications behind the developing of authentic leadership. A survey was conducted on employees of various business areas in Korea, and 448 responses were used in statistical analysis. The results are as follow: First, self-awareness has not shown significantly effective on organizational citizenship behavior and job performance. Second, internalized moral perspective has shown significantly effective toward organizational citizenship behavior and job performance. Third, relational transparency has shown significantly effective for organizational citizenship behavior, but not effective for job performance. Forth, balanced processing of information has not shown significantly effective on organizational citizenship behavior and job performance. This paper makes significant contribution by considering the supervisor's relational transparency and internalized moral perspective, because these authentic leadership dimensions improve employees' OCB and job performance.

Though rocket nozzle flow is very important to the rocket performance, the direct measurement is very difficult because of high temperature and high pressure gas flow. Then the experiment utilizing the hydraulic analogy has been developed for such a problem. Supersonic flows through an axisymmetric De Laval nozzle of solid rocket motor was simulated in a 2-D sluice-type water-table designed and manufactured utilizing hydraulic analogy. Methods to minimize or account for non-analogous effects in the hydraulic system must be reviewed for the quantitative application of the hydraulic analogy. In this application the water table is inclined slightly, so that gravity acceleration has a small component in the direction of motion, thus compensating for the effect of friction. Flow visualization leads to better understanding of the analogous system. Within the experimental errors, it is shown that the hydraulic analogy can be used as an effective tool for the study of two dimensional isentropic flows of gases in many fields.

The court in Korea values evidence justice, and also demands justification for the process of collecting evidence. Therefore, it is necessary to raise the level of organizational commitment, which means that the police investigators performing these tasks feel attached to the police organization they belong to, and that they feel united about the goals of the organization. Based on this recognition, the study analyzed the effects of the police's perception of organizational Justice on organizational commitment, and classified organizational Justice into distributive Justice, procedure Justice and interaction Justice. Therefore, this study analyzes the effect of the police's perception of organizational Justice on organizational commitment and verifies the effect through multiple regression analysis by injecting the trust of Supervisors into a mediating variable. The study was also conducted on the assumption that the trust of Supervisors is important in carrying out the field investigators work in the South Korean police. To achieve the purpose of this research, a total of three surveys were conducted from May 2017 to October 2019 at the National Police Agency using the selection process of investigators and job training courses for the national police, and a total of 500 copies were used as analysis data. Looking at the results analysis of this study, first, it was found that there was a statistically significant static (+) effect on organizational commitment, where the organizational Justice of police officers was a independent variable. Second, the relationship between organizational Justice and organizational commitment has shown that the trust of Supervisors has a mediating effect in korean police organization.

This study examined the impact of learning organization activities on burnout and the moderating effect of supervisor trust in a learning organization. The results of the study shows that among the activities of a learning organization, independent variables in this study, promoting inquiry and dialogue as well as encouraging collaboration and team learning affect burnout. In other words, the dedication of an organization to creating a culture in which various learning approaches are experimented through questioning and giving feedback as well as collaborative learning that can reinforce the effective use of team resources have an impact on reducing emotional exhaustion, which is considered to be at the core of burnout. Plus, these factors reduce impersonalization, which is activated to prevent further emotional exhaustion by dealing with customers, colleagues and jobs in a cold, negative and perfunctory way. In this study, the dimensions of promoting inquiry and dialogue as well as encouraging collaboration and team learning were found to reduce the decline in personal sense of achievement of an employee with a negative assessment of himself or herself derived from a lack of achievement in his or her job. Supervisor trust (integrity, benevolence and ability) had a moderating effect on the relationship between strategic learning leadership and impersonalization/emotional exhaustion. This suggests that the trust of supervisor helps mediate and moderate the emotional exhaustion and impersonalization of organizational members by encouraging leaders to drive change and take the organization to a new direction. The study has provided implications that communication plays an important role in reducing burnout in the learning context such as positive, appreciative inquiry and feedback analysis to identify strength, and that supervisor trust is critical in order to ensure strategic learning leadership exerts greater influence on the organization.

This study is about the impersonal behavior of the supervisor, which is the root cause of 'Workplace Harassment [bullying]', which becomes familiar to Korean workers. For the purpose of the study, characteristics of supervisors are classified into three situations such as personal situation (authoritarian propensity), organizational situation (job insecurity), and personal and organizational situation (self-defensive ambivalence). Then the effects of those propensities on the organizational commitment of their subordinating workers through abusive supervision were analyzed. To this end, separate surveys for team leader and team members were composed. The subjects were male and female workers in large enterprise in Korea. The major results of the study are as follows. First, the three predisposing factors related to the abusive supervision (authoritarianism, job insecurity, and self-defensive ambivalence) made positive (+) effects on the abusive supervision of the supervisor. Second, in the hypothesis 2 regarding the effects of the abusive supervision of the supervisor on the organizational commitment of the subordinates, it was found that the abusive supervision of the supervisor made negative (-) effects on the organizational commitment of the subordinates. Third, in the verification of the hypothesis 3 regarding the mediating effect of the abusive supervision, the three predisposing factors partially mediated the abusive supervision and made negative (-) effects on the organizational commitment of the subordinates.
