Purpose: The purpose of this study was to construct and test a structural equation model on nursing work outcomes based on Youssef and Luthans' positive psychological capital and integrated conceptual framework of work performance. Methods: This study used a structured questionnaire administered to 340 nurses. Data were analyzed using structural equation modeling. Results: Positive psychological capital showed indirect and direct effects on job satisfaction, retention intention, organizational citizenship behavior, and nursing performance. While, the nursing work environment had direct and indirect effects on job satisfaction and nursing performance, it only had indirect effects on intention to work and organizational citizenship behavior. Additionally, a mediating effect on retention intention and organizational citizenship behavior was found between job satisfaction and nursing performance variables. Conclusion: The nursing organization needs to build a supportive work environment and reinforce positive psychological capital to improve nursing performance. Additionally, it needs to actively manage the necessary parameters involved in the stages of job satisfaction, retention intention, nursing performance, and organizational citizenship behavior of nurses. The findings propose the continuous management of nursing personnel based on nurses' attitude outcome, behavioral intention, behavioral outcome, and stage of role performance.

This study examines the influence of control algorithms on dimming performance to determine appropriate control setting when direct/indirect lighting is controlled by a daylight dimming system. Computer simulation were performed for a small office with double skin envelope under various daylight conditions. A retractable fabric shading and Venetian blind were applied for internal and external envelopes under three CIE standard sky conditions. Unshielded and partially-shielded photosensors were used, and three control algorithms were applied for the sensors. In general, dimming level was too excessive due to the direct impact of light from lighting fixture to the photosensor. Providing insufficient lighting output, the unshielded photosensor completely failed to secure required illuminance under any daylight condition. When a partially-shielded photosensor was applied under clear sky, three setting points functioned effectively. Less sensitivity for the partially-shielded photosensor was effective to control the dimming system optimally with reasonable energy saving. However, the daylight dimming control system for direct/indirect lighting does not appear to be energy effective when photosensors without enough shielded area is installed on ceiling where light from fixtures reaches directly.

The purpose of this study was to examine structural relationships among directors' coaching leadership, organizational culture, early childhood teachers' empowerment, teacher-efficacy and job satisfaction. The data were collected from 575 early childhood teachers and analyzed with Pearson's correlation and structural equation modelling analysis. The results were as follows: first, directors' coaching leadership was found to have a direct effect on early childhood teachers' job satisfaction and an indirect effect through organizational culture, teachers'empowerment and teacher-efficacy. Second, organizational culture was found to have a direct effect on early childhood teachers' job satisfaction and an indirect effect through teacher-efficacy. Third, early childhood teachers' empowerment was found to have a direct effect on job satisfaction and an indirect effect through teacher-efficacy. Fourth, teachers' teacher efficacy was found to have a direct effect on job satisfaction. Additionally, directors'coaching leadership was found to be the most important variable predicting early childhood teachers' job satisfaction. These results suggest that improving directors'coaching readership, organizational culture, teachers' empowerment, teacher-efficacy could help facilitate early childhood teachers'job satisfaction.

This study analyzed the effects of ICT technical characteristics of agricultural industry on smart farm entrepreneurial intention by using smart farm effort expectation and smart farm acceptance intention as mediators for smart farm pre-founders. Sub-variables of the technical characteristics of agricultural industry ICT were classified into availability, economics, data convergence and scalability. 349 questionnaires collected from pre-founders living in the country were used for empirical analysis. SPSS v22.0 and Process macro v3.4 were used to analyze the data based on serial multiple mediation model. First, economics and scalability had a positive (+) effect on start-up intention. Second, availability, economics and scalability had a significant effect on effort expectation. Third, effort expectation had a significant positive effect on acceptance intention. Fourth, acceptance intention had a significant positive effect on start-up intention. Fifth, the indirect effects of economics on start-up intention were all significant through effort expectation, through acceptance intention and through both effort expectation and acceptance intention. Sixth, the indirect effect of data convergence on start-up intention was significant through acceptance intention. Seventh, the indirect effect of scalability on start-up intention was significant through effort expectation and through both effort expectation and acceptance intention. As a follow-up study, it is necessary to study for the mediating variables other than mediators introduced in the study or the moderated mediation analysis through the conditional process model in which the moderating variable is introduced.

The purpose of this paper is to decompose the effect of resources of natural parks(NP) on user's satisfaction to answer the research question: What are the causal effects of resources of natural parks on user\ulcorner After reviewing the literature, classification of resources of NP, various approaches and analysis methods employed, we constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 414 visitors at 6 of the 73 NP in Korea in 2001, based on a stratified sampling method. We have analyzed the data using descriptive statistical methods, Pearson's correlation analysis, and a path analysis method. We found that 1) While the indirect effect of topographical feature and valley(TFV), socio-cultural resources(SCR), and climate, sound, and scent(CSS) turned out to be 2.75, 1.20, and 2.00 times higher than that of wild animal and plant(WAP), the direct effect of TFV, SCR, and landscape turned out to be 2.95, 2.88, and 2.64 times higher than that of CSS, 2) The magnitude of causal effects of the three exogeneous variables of TFV, WAP, and SCR and two intervening variables of CSS and landscape on User's satisfaction turned out to be 0.403, 0.048, 0.323, 0.188, and 0.243, respectively, 3) Total direct effect of the exogeneous and intervening variables on user's satisfaction is 0.871, while that of indirect effect is 0.334, and 4) Causal effect of tangible resources is 1.80 times higher than that of intangible while total effect of tangible resources are 1.36 times higher than that of intangible. The research results suggest that 1) Criteria for designation and maintenances of NP and results of previous studies on resources turned out to be unreliable and distorted, 2) In the criteria of planning and maintenance of NP, intangible resources must be included, 3) Remedial directions to increase user's satisfaction should be focused on maintenance of TFV and landscape in NP, and 4) The approach and path analysis adopted by this research is valid and highly useful for other resource based recreation area. It is recommended that more empirical study on seasonal variation of resources in NP based user's preference be performed in the future.

The purpose of this study is to investigate the direct effect of victimization experience on cyber security behavior and the indirect effect of information protection awareness through the Dual Process Theory. Baron & Kenny regression analysis was conducted and the results are as follows - first, victimization experience has a positive effect on cyber security behavior; second, the relationship between victimization experience and cyber security behavior is mediated by cyber security awareness; and third, the direct effect of victimization experience on cyber security behavior and the indirect mediating effect of cyber security awareness are both positive (+). The direct effect of victimization experience on cyber security behavior is analyzed to be relatively large compared to the indirect effect that cyber security awareness has on cyber security behavior. Based on these results, It is suggested that periodic cyber security education and campaign policies are needed to enhance cyber security behavior.

The purpose of this study is to examine the demographic, economic, and psychological factors that influence the quality of life (QoL) of the elderly. The data in the 'Survey on the Elderly in 2011', were collected from The Ministry of Health & Welfare and the Korea Institute for Health and Social Affairs. The samples included 3,312 out of the total of 15,146 elderly people aged from 65 to 70 years. Multiple regression analysis and path analysis were used to analyze the research model. The findings are as follows. First, the most critical factor that affected the QoL of the elderly was "subjective standard of living" with other factors including "subjective physical condition level", "depression", "total annual income", "the number of chronic disease", "self-esteem", "economic supports from their adult children", "education level", "living with their adult children or not", "sex", and "home ownership", in that order. Second, based on the path analysis results, the QoL of the elderly was influenced by "subjective physical condition level", "subjective standard of living", "depression", "self-esteem", "total annual income", "education level", and "the number of chronic disease", in that order. In particular, "depression" had a negative direct effect and an indirect effect on the QoL of the elderly, whereas "self-esteem" had a positive direct effect and indirect effect on their QoL. Third, "labor force participation status" did not affect the QoL of the elderly. However, it implied the mediating effect of "self-esteem" and "depression" on their QoL. These results show that demographic, economic, and psychological factors heavily influence the QoL of the elderly. Specifically, "depression" and "self-esteem" turn out to be mediating variables that strongly influence the QoL of the elderly. Also, "labor force participation status" does not have a positive direct effect on the QoL of the elderly but has a positive mediating effect of "depression" and "self-esteem" on their QoL.
