Purpose: This study examined the relationships among menopausal symptom, self-efficacy, health promoting behaviors, and investigated factors affecting health promoting behaviors of teachers with middle-aged women experiencing menopause. Methods: From September to October 2012, a convenience sample of 252 subjects aged 40 to 60 years was recruited from 8 elementary schools, 3 middle schools and 5 high schools. The data analysis was done by ANOVA and stepwise multiple regression. Results: Menopausal symptom of subjects was slightly lower than general middle aged women and the average level of health promoting behaviors was similar to general middle aged women. Health promoting behaviors were differentiated by severity of menopausal symptom, not by menstruation state. Menopausal symptom was negatively related to health promoting behaviors. The most significant factor affecting health promoting behaviors was self efficacy (14.3%). The combination of self efficacy, menopausal symptom, and elementary school teachers accounted for 20.1% of health promoting behavior. Conclusion: When developing health promotion program for teachers with middle-aged women, such program should consider self-efficacy, menopausal symptom, and school type.

Purpose: This study was conducted to find out the effects of self-efficacy on job stress symptoms and coping strategies depending on perceived job stress. Method: The subjects were 447 workers employed in a manufacturing company. Demographic characteristics, self-efficacy, job stress, job stress symptoms and coping strategies were assessed by a self-administered questionnaire. Each envelope to keep the secret sealed completed questionnaires. Result: Job stress and job stress symptoms in workers with a high level of self-efficacy were lower than those of a low level of self-efficacy. Active coping strategies in workers with a high level of self-efficacy group were higher than those of a low level of self-efficacy. In multiple regression analysis, job stress symptoms were significantly higher in increasing job stress, increasing self-efficacy, office workers, manager group and increasing age. Active coping strategies were significantly higher in increasing self-efficacy, increasing career, males and decreasing job stress. Whereas passive coping strategies were significantly higher in females, increasing job stress and increasing self-efficacy. Conclusion: This study suggests that self-efficacy is a significant factor on job stress, job stress symptoms and coping strategies. Therefore, developing a job stress management program to increase self-efficacy and verifying its effects are needed.

Purpose: The purpose of this study was to identify quality of sleep and its influencing factor among middle-aged male workers. Methods: The subjects of this study were 411 middle-aged male workers living in Seoul and Gyeonggi-do. The data were based from self-reported using structured questionnaires asking about low urinary tract symptoms, circadian rhythm, quality of life and sleep quality including general characteristics. The data were collected from September 11 to October 31, 2013 and analyzed by t-test, one-way ANOVA, Pearson correlation coefficient and hierarchical regression. Results: Mean score of the sleep quality was $5.03{\pm}2.57$ (range: 0~21) and reported as bad sleep quality in 55.7%. Low urinary tract symptoms (${\beta}$=.30, p<.001), circadian rhythm (${\beta}$=-.17, p<.001), quality of life (${\beta}$=-.14, p<.001) were shown as significant association of sleep quality. Conclusion: Strategies to improve sleep quality in middle-aged male workers are necessary and nursing intervention should be developed to improve education program for prevention and management of low urinary tract symptoms. It is also necessary to legalize the institutional devices to upgrade work environment and to place regulations on overtime at work places in order for these workers to obtain sufficient sleep time for recovery of biological rhythms and improving sleep quality.

Purpose: This descriptive study was to examine the effect factors on health promotion lifestyle of shift work nurses. Methods: The 418 working nurses who completed questionnaires with consent were analysed. Results: The average level of health promotion lifestyle of shift work nurses was 2.21 and it was significantly lower than 2.36 of fixed work nurses. In shift work nurses, the highest health promotion lifestyle was personal relationship of 2.79 and the lowest was physical activity of 1.58. The young, shorter shift work duration, unmarried and general nurses were evaluated as not-healthy diet. The old, longer shift work duration and married showed less physical activity. Less self-efficacy and more job stress, depression, fatigue showed lower health promotion lifestyle. Conclusion: Self-efficacy on health behavior of shift work nurses was the most effective factor on all areas of health promotion. Therefore, we need to develop a health promotion program including self-efficacy encouragement. We suggest that this program be more effective when more precisely characterized according to age, marital status, shift work duration, job position, and psychological problems such as depression and fatigue.

Purpose: This study aimed to investigate the level and related factors related to health-promoting lifestyle in operating room nurses in Korea. Method: A cross-sectional descriptive survey design was employed. The data were collected using questionnaire for three weeks in December 2018 from 110 operating room nurses working for more than six months in a general hospital located in Seoul. The Health Promoting Lifestyle Profile-II, The Korean Version of the Practice Environment Scale of Nursing Work Index, and Operating nurse's Job stress Factor Scale were used. Results: Significant relationships were observed between health promoting lifestyle and educational level(p= .025), perceived economic status (p= .001) wearing a lead apron for protection from radiation during the operation(p< .001), work satisfaction(p= .016), and fatigue related to work(p= .006). Also significant correlations were identified between nursing work environment and health promoting lifestyle. However, the health promoting lifestyle was not statistically different based on occupational stress(p= .365). In multiple linear regression analyses, the level of health promoting lifestyle found to be higher in subjects who did not wear a lead apron for protection from radiation(p= .017), and who had more positive perception of the nursing work environment(p= .034). Conclusion: In order to increase health promoting lifestyle of operating nurses, the strategies to improve the nursing work environment are essential.

Many occupational workers or professionals have to walk on the various floors for a long period of time. The objective of this study was to develop the safety shoes with increased traction through the material selection. In order to fulfill our objective, first, two kinds of filler were selected to compare the wear mechanism at outsole surface. The developed rubber materials were tested with two kinds of portable slip meters. The sample safety shoes with developed rubber materials were also tested with subject in the laboratory. During walking, the safety shoes were naturally abraded with counter surface. The coefficient of friction(COF) was gradually decreased with number of steps to 30,000, while the COF was abruptly increased from 30,000 to 40,000. The experimental results showed that COF tested with silica rubber was at least 10% higher than that with carbon black rubber in wet or detergent condition. It has been well recognized that filler properties play a important role in wet traction in the tire industry. However it has been unclear that filler properties would be decisive factor in safety shoes. Our study shows that silica exhibits a higher slip resistance than carbon black without reference to wear states in wet or detergent condition. So, this results will provide guides for outsole compounders to develop new products and improve product performance.

Purpose: This study aimed to examine the factors associated with behavior that reduces exposure to environmental hormones among nursing students. Methods: Data were collected from 160 nursing students in D and B cities, using self-report questionnaires. Data were analyzed using SPSS 22.0, and the analyses included descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient test, and stepwise multiple regression. Results: Behavior that reduces exposure to environmental hormones differed significantly in terms of the participants' knowledge about environmental hormones. Behavior that reduces exposure to environmental hormones was negatively correlated with knowledge of environmental hormones, attitude towards pro-environmental behavior, and environmental self-efficacy; these factors were significant predictors of behavior that reduces exposure to environmental hormones, and accounted for 27.0% of the variance. Conclusion: Environmental self-efficacy was identified as the most significant factor affecting behavior that reduces exposure to environmental hormones in nursing students. Therefore, it is necessary to develop programs to improve pro-environmental behavior and environmental self-efficacy in nursing students.
