Purpose: The purpose of this study is to identify the factors that influence HRQOL for married working women. Methods: The subjects of the study were 577 full-time working married women living in five province. The data were collected using a structured questionnaire, from April to September 2006. Results: As for the general characteristics, there was a statistically significant difference in the level of HRQOL(total) according to age, education, menopause, family income, leisure activities, residence, duration of marriage, number of children, firstborn age, household duties of husband, job, career, type of work, women's income, and purpose of working. The level of HRQOL showed a statistically significant difference according to BMI and behavioral factors except for caffeine intake and follow up health screening. The HRQOL were significantly correlated with depression, marital satisfaction and job satisfaction. The multiple regression analysis showed that the HRQOL were significantly predicted by depression, marital satisfaction, education, regular exercise, daily working hours and job satisfaction. These variables explained 48.5% of the variance of HRQOL. Depression was the main predictor of HRQOL. Conclusion: It could be concluded that nursing intervention to reduce depression should be developed to promote the HRQOL for married working women.

Objective: This study intended to examine whether working mothers' job satisfaction has a moderating effect on the relationship between their parenting stress and second childbearing intention. Methods: The subjects were 202 working mothers in Seoul and Gyeonggi province, all of who had a single child under 36 months old. Working mothers' parenting stress, job satisfaction and second childbearing intention were assessed with questionnaires completed by the mothers. The data were analyzed using descriptive statistics, t-test, one-way ANOVA, Duncan test, Pearson's correlation, and moderator regression analysis. Results: First, a significant difference was revealed in the mothers' second childbearing intention depending on the type of their child's main caregiver. The second childbearing intention of the mothers who relied on babysitters to care for their children was lower than that of the mothers whose mothers, mother-in-laws or child care teachers cared for their children. Secondly, working mothers' parenting stress and job satisfaction significantly affected their second childbearing intention. Thirdly, the mothers' job satisfaction moderated the relationship between their parenting stress and second childbearing intention. Conclusion/Implications: It is necessary to provide working mothers with social support for enhancing their job satisfaction and alleviating their job stress, in order to increase their second childbearing intention.

The main purpose of this study is to obtain forest scenic beauty management informations toward forest working systems in pinus densiflora forest stands, etc. To get these information, visual preference and spatial image analysis methods are used. 25 different alternatives were simulated to visualize on basis of actual forest working methods with taken photos from May to July, 2003. The options were illustrated as photos produced by computer software. Respondents' ratings for 25 landscape scenes were obtained by interview survey method. Each alternatives were evaluated by forest major student group with total 103 respondents after reliability test. Visual preference evaluation was used 10 point rating scale. Spatial images of 12 alternatives were measured by 12 semantic differential scale. In general, the respondents preferred refreshing and ordering forest stand after forest working to natural forest stand before forest working. High visual preference for forest density produces 400-600 trees/ha in small diameter class forest stands. Regarding visual preference according to pavement type of trail, soil trail is ranked high. Visual preference for cutting area ranks mature forest stand and visual preference for trail slope cover type ranks shrub with grass as relatively high on the preference scale. Through the factor analysis, spatial images of 12 coniferous forest stands are classified as 'ordered opened' and 'beautiful healthy'. Results indicate how to conduct forest working systems for forest scenic beauty management.

The purpose of the study was to investigate social support, depression, drinking and smoking in college and working females. The convenience sample consisted of 169 college females and 133 working females. Data were collected from March to May, 2000. Social support was measured by the 6-item Social Support Questionnaire which assesses the size of the emotional social support network and satisfaction with social support. The Center for Epidemiologic Studies Depression scale was utilized to measure the level of depression symptoms. The average number of drinks and cigarettes smoked per week during the previous month was assessed. Results indicated that college students had more social support than working females. However, there were no significant differences in satisfaction with their support, depression, drinking and smoking between two groups. College females who smoked cigarettes were more depressed and had less social support than those who did not smoke. Also college females who drank alcohol were more depressed than those who did not drink during the previous month. However, the level of social support and depression were not associated with drinking and smoking among working females. Based on the results, it is suggested the application of various interventions to deal with drinking and smoking behavior among college and working females.

This paper describes an experimental study on fatigue life extension by using cold working process in fastener hole of aircraft structure. Cold working process was applied for A12024-7351 specimens by considering the effect of edge margin on fatigue life. It is generally recognized that cold working process offers a protective zone around fastener hole of aluminum aircraft structure due to the residual compressive stresses which lead to retardation of crack growth. Thus this process provides the beneficial effect of increasing the fatigue life of the component. there by decreasing maintenance costs. It has also been successfully incorporated into damage tolerance and structural integrity programs. Cold working specimens were tested at constant amplitude peak cyclic stresses. Fatigue life of cold working specimen compared with that of specimen fabricated with base material. The increase of fatigue life for cold working specimen is discussed by both considering the effect of residual compressive stresses measured by X-ray diffraction technique and quantitative effect of edge margin.

A fast and inexpensive approximate analysis method to predict power output characteristics of the Stilting engines in a preliminary design stage was investigated. In basic equations proposed by Walker, typical temperatures of working fluids in expansion and compression spaces were treated as those of working fluids in heater and cooler respectively. While the temperature of working fluid in the expansion space was actually lower than that of working fluid in the heater, the temperature of working fluid in the compression space was higher than that of working fluids in the cooler. In this paper, the working fluid temperature of expansion space was treated as lower than the heater temperature and that of compression space was treated as higher than the cooler temperature. Also, according to them, the power output characteristics of the Stirling engine were evaluated with respect to the GPU-3 and 4-215 Stilting engines. The following conclusions were drawn from the analysis. 1. Using the available experimental data from the GPU-3 Stirling engine, it was shown that the approximate analysis predicts the brake power with a maximum error of 19 percent at 1, 000rpm and with a minimum error of 3 percent at 2, 000rpm. 2. The approximate analysis data which for the GPU-3 Stirling engine were much closer to the experimental data than those of adiabatic 2nd order and 3rd order analysis within 1, 500rpm to 2, 500rpm. 3. The approximate analysis data which for the GPU-3 and 4-215 Stilting engines were much closer to the experimental data than those of the Beal number analysis.

This paper explores the relationship between working hours and the residual gender wage gap in Korea. Because the labor practice of working long hours in Korea favors men, who tend to spend little time on domestic labor, long working hours can influence the residual gender wage gap by discriminating against women. We analyze this discrimination empirically, and find the following results. First, the returns from working long hours are not high in most occupations in Korea. Second, working hours have a positive effect on the residual gender wage gap in male-dominated occupations, but not in female-dominated ones.
