Objective: The purpose of this study was to examine the direct and indirect effects of mothers' and children's emotional instability and maternal affectionate-rational parenting on children's attributional style. Methods: The participants of this study were 253 4th, 5th and 6th grade elementary school students and their mothers in Seoul and Incheon. Data were analyzed by path analysis using AMOS 21.0. Results: The results were as follows: First, children's attributional style for negative and positive events was significantly related to children's emotional instability and maternal affectionate-rational parenting. Also, mothers' and children's emotional instability was significantly associated with affectionate-rational parenting. Second, mothers' emotional instability had indirect effects on children's attributional style for negative and positive events through maternal affectionate-rational parenting. Finally, children's emotional instability had not only significant effects on children's attributional style for positive achievement events, but also indirect effects on children's attributional style for negative and positive events through maternal affectionate-rational parenting. Conclusion/Implications: The results of this study suggest that both environmental and individual factors, including mothers'and children's emotional instability and maternal affectionate-rational parenting, need to be considered to explain children's attributional style. Also, these findings have implications for developing intervention programs for children's attributional style and parental education.

Purpose: In Korea, win-win growth policy has been successfully implemented in supply chain and logistics management. In the policy, it is recommended to support supply chain partners with various mechanisms including financial and technical aids. This study attempts to scientifically analyze the effects of direct and indirect win-win growth policy factors on supply chain and logistics management performance through partnership factors. Research design, data and methodology: This study builds a structural equation model reflecting the relationship between the win-win growth policy, partnership and performance factors. The proposed model is verified with the PLS (Partial Least Squares regression) methodology. Data from shipper and logistics companies were collected and analyzed by the PLS model. Results: The analysis showed that both direct and indirect policy factors are meaningful to improve supply chain and logistics performance. Indirect support factors including R&D, management innovation, human resources development and educational supports have positive impacts on partnership factors. Direct support factors including financial aids and fairness also have positive impacts on the performance. Conclusions: This study is meaningful in that it suggests a turning point in which supply chain Win-win growth and partnership efforts are perceived as new value-creating mechanism rather than unilateral cost reduction for logistics industry.

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 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 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.
