Purpose: The purpose of this study was to describe and understand elementary school health teachers' role perception in their own perspectives. Methods: Data were collected from three focus groups composed of five participants for each group. Each focus group had an interview for two and a half hours on the average. The main question was "What is your perception on the roles of health teachers in elementary schools?" Qualitative data from transcribed notes and field notes were analyzed using qualitative content analysis. Results: Five main roles were identified from the participants. The participants perceived themselves as 'an expert of health education in school and community', 'a health service provider for school members', 'a health guardian for school members, the coordinator of healthcare related works in school, and the leader of school health. Conclusion: The participants have multiple role identities, which are very important for health management of school members. And the roles such as an expert of health education and a leader for school health are recently emphasized. The findings of this study can provide useful information to design orientation programs for newly appointed health teachers and continuing education programs for enhancing role performance of health teachers in elementary schools.

The disposition towards volunteer work and leadership traits are the basic qualities that should be possessed by teenagers who are to become next generation leaders. The 'Volunteer Work and Leadership' program was developed to attain this goal and all S high school students were subjected to this program. This program was comprised of four modules, and this dissertation is focused on the second module: 'Wisdom Leader'. This program, which was conducted for six hours on a daily basis, was carried out two times per day during the first semesters of 2006 and 2007 on freshmen students. The program was comprised of three conceptual frameworks-Education of the heart that improves your emotion which includes 'cultural performance', 'volunteer work leadership group performance' and 'spot strategy for stress management'. Education of the hand pursues knowledge, which includes 'special lecture of leadership' and 'leader research through movies', and Education of hand which students directly participate in workshops were also used. After studying the results of the program, it was found that the satisfaction level of the education was higher during the second session than the first session. Therefore the objective of this program to enhance the leadership qualities of students was attained Also, this dissertation was able to reaffirm the relationship between volunteer work and leadership. I hope that the leadership content can be used systematically for enhancing the educational effect of volunteer work.

Purpose: The purpose of this descriptive study was to identify the impact of workplace bullying and LMX (Leader-Member Exchange) on turnover intention among nurses. Methods: The participants were 364 nurses from the Seoul metropolitan area who were attending a continuing education program. A structured questionnaire was used for data collection and data were analyzed using the SPSS/Window program. Hierarchical multiple regression analysis was performed to verify the effect of variables on turnover intention. Results: Higher workplace bullying was associated with higher turnover intention. Workplace bullying was negatively correlated with leader-member exchange. The most influential factors for turnover intention were LMX (${\beta}=-7.22$, p<.001), work load (${\beta}=2.96$, p=.003), and workplace bullying (${\beta}=2.64$, p=.009). These factors accounted for 28% of the variance in turnover intention. Conclusion: The study results indicate that there is need to develop strategies to prevent workplace bullying and cultivate a good relationship between nursing managers and nurses to lower nurses' turnover intention.

The purpose of this study is to verify the research model and identify the causal relationship among leader's super leadership, self-leadership, psychological empowerment, sport commitment and performance perceived by Taekwondo athletes. The subjects of the study were middle and high school Taekwondo athletes registered in the Korea Taekwondo Association in 2020 and 2021, and data from 454 people were used as final effective samples through convenience sampling. The collected data used the SPSS 23.0 version and the Amos 21.0 version to verify the hypothesis. As a result, the following conclusions were obtained. First, we discovered that the leader's super leadership had a positive impact on the athlete's self-leadership, psychological empowerment, and sport commitment. Second, we found that the athlete's self-leadership had a positive effect on psychological empowerment, sport commitment, and performance. Third, we found that athlete's psychological empowerment had a positive effect on sport commitment and performance. Fourth, we found that the athlete's sport commitment had a negative effect on performance. Therefore, this study has reminded us about importance of psychological empowerment and sport commitment for explaining the relationship between leadership type and performance perceived by Taekwondo athletes, and might contribute to the theoretical discussion of variables related to athletes' performance.

The purpose of this study Is to verify relationship between leadership styles ( consideration leadership and Initiating structure leadership) and Job satisfaction In university libraries. The conclusions in this study are summarized as follows： 1. Correlations between leadership styles and job satisfaction are positive. Consideration leadership is higher correlation than initiating structure leadership. 2. Leadership styles have affected on Job satis-faction (promotion, task, salary, superior, fellow) differently. Consideration leadership is higher influenced than initiating structure leadership except satisfaction of task. 3. It is no difference that leadership styles have affected on job satisfaction by a characteristic(sex, school career, librarian's license) of person. As consideration leadership is higher correlation and influence than initiating structure leadership, leader should have done consideration leadership and then library's staffs can get job satisfaction in order to achieve job satisfaction, leader had better show consideration leadership regardless of sex. school career and librarian's license. leadership styles have influenced Job satisfaction differently. It shows indirectly that library's staffs are not discriminated by sex, school career and librarian's license.

본 논문은 기존 PSO의 문제점으로 지적되는 Local minimum에의 고착을 해결하여 평균적인 성능을 향상시킬 수 있는 방법을 제안한다. 이를 위해 기존에는 하나의 Best Value만을 향해서 이동하는 것에서 벗어나, 각 Particle들을 Cluster로 나누고 각각의 Best Value를 중심으로 이동하며, 각 Cluster Leader들은 다른 Cluster Leader와 통신하며 순위에 따라 이동한다. 제안 방법으로 수렴속도와 Local minimum 회피에 대해 실험을 통해 비교 분석한다. 실험 결과로부터 제안 방법이 Local minimum 회피에서 성능 향상이 있음을 고찰하였다.

In this paper, we propose a new location service and location-based routing for data dissemination from a source to a mobile group sink in less energy consumption of the sensor node. Unlike the existing protocols, the proposed protocol uses a leader sink instead of a group area as the location information to represent a mobile sink group. The proposed protocol also uses grid leaders on virtual grid structure to support sink mobility in location service. By using a leader sink as a representative and grid leaders for mobility supporting, the proposed protocol can exploit an efficient hierarchical location service and data dissemination method without using flooding. Accordingly, the proposed protocol carries out upper layer location services and data dissemination between a leader sink and a source and lower layer location services and data dissemination between the leader sink and member sinks. Simulation results demonstrate that the proposed protocol achieves energy-efficiency.
