In a military maintenance system, the standard maintenance man-hour of weapon systems is a tool to estimate the maintenance capabilities of maintenance units, provide standards for determining the maintenance needs and workload, and provide basic data for establishing a maintenance plan. The standard maintenance man-hours of major weapon systems have already been derived and used, but the standard maintenance man-hour in a wartime maintenance environment has not been computed. Therefore, the standard wartime maintenance man-hours need to be derived and This study proposes a process and method of computing the maintenance man-hours. In addition, this work suggests the criteria of collecting and screening data that is necessary for estimating the standard maintenance man-hours and introduces a methodology for analyzing the characteristics of maintenance man-hour distribution in the process. The proposed process first designs a model that reflects the wartime maintenance environment, selects statistical techniques, collects maintenance data, analyzes the descriptive statistics, estimates the distribution, and finally presents representative values of maintenance man-hour. Based on the proposed method, the standard wartime maintenance man-hours of the four weapon systems were calculated, and the distribution of the maintenance man-hours was analyzed to follow a lognormal distribution, and the method presented reliable results.

The main purpose of this study is to examine the relation between different patterns of commitment to work role and fathering and the level of life satisfaction. 272 fathers, whose oldest child is under 12 years old with professional, managerial and clerical jobs, were selected. The major findings of this study were as follow: 1) Married men with the oldest child under 12 years old were more likely to be committed to fathering than to work role. 2) The significant variables that affected the level of commitment to fathering were the age of the oldest child, the frequency of participation in the meeting after work, parental satisfaction, and how they perceive the spousal support. And the significant variables that affected the level of commitment to work role were type of job, parental distress, work satisfaction, work distress. 3) Patterns of commitment to fathering and work role were categorized into four groups. The names were given as positively balanced commitment pattern, positive fathering commitment pattern, negative fathering commitment pattern, and totally negative commitment pattern. 4) The significant variables important in classifying the patterns of commitment to work role and fathering appeared to be the age of the oldest child, work distress, the frequency of participation in the meeting after work, parental satisfaction, how they perceive the spousal support, work satisfaction and weekend total working hour. 5) The balanced positive commitment to work and fathering was associated with the highest level of life satisfaction.

The purposes of this study are to provide background information to develop a family-friendly work policy and to increase the effectiveness and feasibility of this policy. We surveyed the performance of family-friendly work policies, and workers‘ needs and utilizations of 17 family-friendly work policies. We also examined the factors that influence the utilization of family-friendly work policies. The study sample consists of 197 working mothers who have at least one child under age 10. The major findings are as follows: 1) The most-needed family-friendly work policy among working mothers is child care leave 2) Of those family-friendly work policies that are not currently provided, the most-needed policy is family care leave 3) The size of firms, the provision of substitutes, and 40-hour work schedules are statistically significant variables that influence the provision of necessary family-friendly work policies and 4) In addition, the work place culture is a very important factor related to the utilization of work- and family-friendly policies.

Purpose: This study aimed to investigate the relationships between the characteristics of nurses' work schedules, health outcomes, and work-life balance. Methods: This was a secondary data analysis that included 422 nurses in Korean hospitals. Descriptive analysis, independent sample t-test, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis were used to identify the associated factors. Results: Multiple linear regression analysis showed that work-life balance was lower when atypical work was performed (β=-.14, p=.010). Nurses who did not work overtime showed a higher level of work-life balance than those who worked overtime infrequently (β=-.11, p=.002) or frequently (β=-.28, p<.001). The work-life balance level increased when nurses had better subjective health status (β=.16, p<.001) or higher sleep quality (β=.29, p<.001). It was verified that the work-life balance level was higher for single-person households than for households with two (β=-.18, p=.003), three to four (β=-.16, p=.022), or five or more (β=-.21, p<.001) persons. Conclusion: This study suggests that government and hospital organizations should provide high-quality care and consideration to nurses who do atypical or overtime work as well as their subjective health status and sleep quality. Further research should focus on the development of a policy that improves the work-life balance of nurses, especially for those who work during atypical hours.

Purpose: This was a descriptive observational study examining the reasons for, frequency of, and factors affecting work interruption among intensive care unit (ICU) nurses. Methods: Convenience sampling was used to recruit 46 regular nurses who had been working in an ICU at D tertiary hospital in B metropolitan city for at least six months. To measure the degree of work interruption, this study revised a tool used by Brixey et al. (2007) for analyzing the type of work interruption. Results: A total of 1,787 work interruptions occurred during 368 hours of observation, i.e., at an average of 4.85 times per hour. Communication-related factors caused work interruption most frequently, followed by environmental, work-related, and personal factors. As for the work-related characteristics of nurses, participants experienced work interruption more frequently while working on weekdays, when the medical staff were stationed, than on weekends. Conclusion: ICU nurses experienced work interruption frequently. With the health care system expected to become more complicated in the future, efforts should be made to reduce unnecessary work interruptions to improve the operation efficiency of ICUs.

The purposes of this study were to analyze the structure of time use in farm households, and to compare the time use structure of women farmer with that of their husbands. The data for this study were collected from 276 farm households, selected from 8 provinces in the country. The data were collected at two times of farming season and off－farming season and classified as farm labor and household labor by labor types. SPSS(ver 12.0) statistical package was utilized to analyze the data, and t－test was performed for this study. The major findings are as follows; 1) In the case of work directly related to farming, husband's working hour was significantly longer than that of wife during the farming and off－farming season. In contrast with wife's household working hour was significantly longer than that of husband during both seasons. 2) There existed a severe work time imbalance between wife and husband during the-farming season. Based on the findings of this study, the following implications could be drawn to promote efficient labor and equal labor sharing. First, the consciousness has to be changed because the impartial labor sharing roles. We have to develope many programs to break these fixed ideas. And these programs have to be included to educational course and be instructed continuously. Second, the role of wife that household and farming work is important and will be magnified in the future.
