The purpose of this study was to review journal articles, master's theses, and doctoral dissertations on self-leadership in nurses in order to identify overall trends in nursing self-leadership and to suggest strategies to improve self-leadership. Methods: Twenty-six papers on self-leadership in nurses were reviewed. Results: These papers were journal articles, master's theses, and doctoral dissertations regarding nurses who worked in general hospitals, university hospitals, and public health centers. Self-leadership was measured by using instruments developed by Manz (1983), Prussia, Anderson, & Manz (1998), and Houghton & Neck (2002). The instrument was composed of 18 items, with a 5-point Likert scale developed by Manz (1983) and modified by Kim (2002). Nurses' self-leadership was found to be related to job satisfaction, organizational commitment, nursing performance, and citizenship behavior. General characteristics of nurses, including age, education, marital status, position, and career, were also associated with self-leadership. Conclusion: The study findings provide data on recent trends in nurses' selfleadership. These results serve as basic data to provide a standard for developing self-leadership and indicate directions for further research.

The aim of this study was to identify the closeness, self-esteem and intention of exercise maintenance in the elderly participants of the BeHaS exercise program. Methods: Thirty-one elderly participated in the BeHaS exercise program which held 1 hour a week for 8 weeks. Data were collected by self-report questionnaires. Analysis of data was done using UCINET 6.0 for closeness and SPSS 22.0 program for frequency and Wilcoxon signed rank test. Results: The score of closeness, self-esteem and intention of exercise maintenance in pretest were significantly higher than those of posttest relatively(p<.001, p=.040, p=.007). Conclusion: These findings suggest that the BeHaS exercise program for elderly can be effective nursing care to improve closeness, self-esteem and intention of exercise maintenance.

Purpose: The purpose of this study was to identify the relationships among network centrality, psychological well-being (PWBS), and intention to exercise maintenance in participants of an aquatic exercise program. Methods: Using a single-experimental design, 17 osteoarthritis patients participated in an aquatic exercise program. The questionnaire to connect the network of members was used to peer nomination by Moreno (1953). Data were analyzed with the UCINET using centrality (degree, closeness, betweenness) and SPSS using descriptive statistics, wilcoxon signed ranked test, and spearman's rho. Results: Closeness centrality, PWBS, and intention to exercise maintenance were significantly different between 4 weeks and 8 weeks. At 4 weeks, PWBS was positively correlated with closeness centrality. Intention to exercise maintenance was positively correlated with degree, closeness, and betweenness centrality. At 8 weeks, PWBS was positively correlated with closeness centrality. Intention to exercise maintenance was positively correlated with closeness centrality. Conclusion: The aquatic exercise program can be effective in increasing closeness centrality, psychological well-being, and intention to exercise maintenance. This was the first study attempted to analyze construction of member relationships in osteoarthritis patients participating an exercise program by using social network analysis.
