This paper presents a development of an educational simulator of particle swarm optimization (PSO) and application for solving the test functions and economic dispatch (ED) problems with nonsmooth cost functions. A particle swarm optimization is one of the most powerful methods for solving global optimization problems. It is a population-based search algorithm and searches in parallel using a group of particles similar to other AI-based heuristic optimization techniques. In developed simulator, lecturers and students can select the functions for simulation and set the parameters that have an influence on PSO performance. To improve searching capability for ED problems, a crossover operation is proposed to the position update of each individual (CR-PSO). To verify the feasibility of CR-PSO method, numerical studies have been performed for two different sample systems. The proposed CR-PSO method outperforms other algorithms in solving ED problems.

Purpose: This study was to identify the relationship between stress, social support and depression in the elderly. Method: The subjects were 283 elderly adults over 60 in Seoul. Data was collected by questionnaire surveys using convenience sampling. The instruments used in this study are the ELSI developed by Aldwin(1990), the Interpersonal Support Evaluation List developed by Cohen & Hoberman (1983), and the Geriatric Depression Scale by Yesavage & Brink(l982). Data was analyzed by the SAS program, using descriptive statistics, Pearson Correlation Coefficient, t-test, ANOVA and progressed Multiple Regression. Result: The relationship between stress and depression had a positive correlation (r=0.33), but the relationship between stress and social support had no significant correlations. The relationship between social support and depression had a negative correlation (r=-0.38). The most powerful predictor of depression was the economic status and then a combination of stress, and social support account for 39% of the variance in depression in the elderly. Conclusion: These results suggested that stress and social support deficits can be potential risk factors in old age depression. Therefore, these findings give useful information for constructing an intervention program focused on depression in the elderly.

Purpose: The purpose of this study was to identify the relationships among emotional labor, empowerment, job burnout, and turnover intention. Methods: The design of this study was a cross-sectional descriptive study. The subjects of this study were 358 nurses working for over 6 months in Seoul and Gyeonggi-do. The data were collected from 4th to 30th of September, 2009 through one-to-one interviews. Survey data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical regression. Results: We find the positive correlation of turnover intention with emotional labor and with job burnout, but the negative correlation of empowerment with job burnout and with turnover intention. The nurses' turnover intention scores were relatively low with 1.30. Job burnout, shift work, and frequency of turnover were predictors of turnover intention. The most powerful predictor variable was job burnout (${\beta}$=.420, p<.001). We find that emotional labor and empowerment as determinants of turnover intention are not significant. Conclusion: These results suggest that manager should consider shift work of nurses and job burnout in order to manage nurse organization and resource effectively.
