This study was conducted to investigate the factors affecting depression in elementary school teachers. The research design was a descriptive study. Methods:Data were collected by questionnaires from 283 elementary school teachers. Data were analyzed using a t-test, ANOVA, a $Scheff{\acute{e}}$ test, correlation analysis, and multiple regression analysis. Results: The mean scores were 2.44, 3.07 and 3.68 out of 5 on Likert scales for burnout, job stress and ego-resiliency, respectively. The mean scores were 1.47 and 2.95 out of 4 on Likert scales for items of depression and job satisfaction, respectively. Teaching experience and class size affected depression significantly. There was a positive correlation between depression and burnout(r=0.465, p<.001), and between depression and job stress(r =.220, p<.001),while a negative correlation was observed between depression and job satisfaction(r=-.249, p<.001), and depression and ego-resiliency(r=-.643, p<.001). Multiple regression analysis showed that ego-resiliency(${\beta}=0.639$), job satisfaction(${\beta}=.141$), burnout(${\beta}=.094$), and job stress(${\beta}=.067$) affected depression in order and the four research variables led to a 42.7% prediction for depression among elementary school teachers. Conclusion: Based on the results of this study, a systematic plan for decreasing job stress and increasing eco-resilience is needed to improve depression among elementary school teachers.

Purpose: This study was conducted to identify the factors that influence nurses' organizational citizenship behavior. Methods: A cross-sectional design was used, with a convenience sample of 547 nurses from four university hospitals in Seoul and Gyeonggi province. The data were collected through a questionnaire survey done from September 22 to October 10, 2008. The tools used for this study were scales on organizational citizenship behavior (14 items), self-leadership (14 items), empowerment (10 items), organizational commitment (7 items), job satisfaction (8 items) and transformational transactional leadership (14 items). Cronbach's alpha and factor analysis were examined to test reliability and construct validity of the scale. The data collected were processed using SPSS Window 15.0 Program for actual numbers and percentages, differences in the dependent variable according to general characteristics, and means, standard deviations, correlation coefficients and multiple regression analysis. Results: The factors influencing nurses' organizational citizenship behavior were identified as self-leadership ($\beta=.247$), empowerment ($\beta=.233$), job satisfaction ($\beta=.209$), organizational commitment ($\beta=.158$), and transactional leadership ($\beta=.142$). Five factors explained 42.0% of nurses' organizational citizenship behavior. Conclusion: The results of this study can be used to develop further management strategies for enhancement of nurses' organizational citizenship behavior.

Purpose - This study introduces a methodology for finding the optimal tracking error of active stock funds. Tracking error is commonly used in risk budgeting techniques as a concept of cost for alpha creation. Design/methodology/approach - This study uses a post-optimal smart beta portfolio that maximizes alpha under the given tracking error constraint. Findings - As a result of the analysis, the smart beta strategy that maximized alpha under the constraint of 0.15% daily tracking error shows the highest IR. This means the maximum theoretically achievable efficiency. In this regard, a fixed-effect panel regression analysis is conducted to evaluate the active efficiency of domestic stock funds. In addition to control variables based on previous studies, the effect of tracking error on alpha is analyzed. The alpha used in this model is calculated using the smart beta portfolio according to the size of the constraint of the tracking error as a benchmark. Contrary to theoretical estimates, in Korea, the alpha performance is maximized under a daily tracking error of 0.1%. This indicates that the active efficiency of domestic equity funds is lower than the theoretical maximum. Research implications or Originality - Based on this study, it is expected that it can be used for active risk management of pension funds and performance evaluation of active strategies.

This study investigated the effects of overtime work on the health-related quality of life (HRQoL) of Korean blue-collar workers. This cross-sectional study collected data on 229 Korean blue-collar workers in six small-sized companies from October to November 2015. The data were analyzed using hierarchical multiple regression analysis to estimate the effect of overtime work while considering convergence variables. In the hierarchical regression model, when overtime work variable was included in the model, $R^2$ change was statistically significant. The significant predictors for HRQoL were overtime work (${\beta}=.152$, p=.025), depression (${\beta}=-.192$, p=.003) and night shift work (${\beta}=-.201$, p=.032). The results of this study provide a basic data for establishing optimal working hours standards for improving the quality of life of Korean blue-collar workers.

Purpose: This study examined the associations of job stress and burnout with the quality of life (QOL) among 119 emergency medical technicians (EMTs). Methods: Using a descriptive correlational design, 260 EMTs working in D City or S City completed the questionnaires. Hierarchical multiple regression analysis was conducted to determine the predictors of QOL among 119 EMTs. Results: Overall, there was relatively low job stress among 119 EMTs. There were significant differences in job stress and burnout by general characteristics, especially regarding those of gender, service career, job rank, and self-reported health. In a hierarchical multiple regression, general characteristics explained 29% of QOL (Model I, F=16.369, p<.001). The explanatory power for QOL increased to 49% upon adding job stress (Model II, F=18.737, p<.001), and 59% upon adding burnout (Model III, F=22.621, p<.001). In the last model, self-reported health (${\beta}=.316$, p<.001), job demand (${\beta}=-.130$, p=.009), job insecurity (${\beta}=-.136$, p=.010), lack of reward (${\beta}=-.189$, p=.001), emotional exhaustion (${\beta}=-.196$, p=.004) and lack of personal accomplishment (${\beta}=-.334$, p<.001) were significant predictors of QOL among 119 EMTs. Conclusion: Based on the results, it is necessary to assess and manage job stress and burnout systematically among EMTs, and to develop health improvement programs for better QOL.
