This study set out to investigate if work-family conflict and work-family enhancement would have mediating effects on the impact of gender role attitudes of women from double income households on their satisfaction of work and marriage. A structural modelof gender role attitudes was set as the independent variable, work-family conflict and work-family enhancement as the mediating variables, and work satisfaction and marriage satisfaction as the dependent variables. The subjects consisted of 2,713 married women from double income households and information was obtained from the first year data of the Korean Longitudinal Survey of Women and Families (KLoWF) collected by the Korean Women's Development Institute (KWDI). Using SPSS 15.0 software, descriptive statistics were gathered, and frequency and factor analyses were conducted. AMOS 7.0 software was used to analyze both the measurement model and the structural model. The results indicate that work-family conflict and work-family enhancement had partial mediating effects on the impacts of gender role attitudes on work and marriage satisfaction among women from double income households. Notably, work-family enhancement had a greater effect than work-family conflict, which suggests that the elements of work-family enhancement, which are the positive aspects of work on family and family on work, should be promoted. It is, however, also important to make efforts to resolve work-family conflict by increasing the satisfaction level of work and marriage among women from double income households.

Loewner ([13]) showend the semigroup of the real non-singular totally positive matrices is generated by itsinfinitesimal elements, that is,s the set of all Jacobi matrices with non-negative off-diagonal elements. In general, a semigroup is not completely recreated from the set of its infinitesimal elements. We extend Loewner's work and show that the semi-group of all invertible upper (or lower) triangular stochastic matrices is generated by the set of its infinitesimal elements.

본 연구에서는 오토인코더의 재구성 오류의 임계값을 이용하여 가스 시설에서의 작업이 정상 작업인지 비정상 작업인지를 판단하는 알고리즘을 구축하였다. 이 알고리즘은 정상 작업의 시계열 데이터만으로 오토인코더를 학습하여 최적화된 정상 작업의 재구성 오류의 임계값을 도출한다. 이 알고리즘을 새로운 작업의 시계열 데이터에 적용하여 재구성 오류를 구한 다음 이것을 정상 작업의 재구성 오류 임계값과 비교하여 정상작업인지 비정상 작업인지를 판별한다. 이 알고리즘을 학습하고 검증하기 위해서 가상의 가스 시설에서의 작업을 규정하고 정상 작업 데이터로만 이루어진 학습 데이터 세트와 정상 작업과 비정상 작업 데이터를 모두 포함한 검증 데이터 세트를 구축하였다.

According to the Labor Standard Law in Japan which was enacted after World War II in 1947, all work hours for adult men, women, and youth were set at a maximum of eight hours per day and forty-eight hours per week. In other words, a six-day work week, with only one-day off, was set. Now we are in the full five-day and two-day off school system. The five-day school week influences on our home life. Students are highly enthused by the new system, in looking forward to their personal time they now have to play with friends, to relax, or just watch TV. To implement this new five-day school system positively and effectively, we should see the point at issue related to the two-day off system from a different angle, which suggests that we should see far ahead into the future.

To maximize effectiveness of standardization activities, it is essential to set priorities for determined standardization work items in the next generation internet protocol television (NG-IPTV) technologies. In this study, the analytic hierarchy process(AHP) is employed and applied to ranking of NG-IPTV standardization work items as a multi-criteria decision making tool which involves comprehensive surveys. Survey results are analyzed and we identified a useful three level segmentation of standardization strategic plan which shows standardization work item priorities.

Human being does work to live out and they have their private life because human has sociality. Both work and life are important to live out but they are on the trade-off relationship. Because keeping the balance between work and life is too hard, it has been interested by academic and practical areas. Definition of Work-life balance here is that balance or imbalance arising between work and life has no negative impact on their daily life. Above all, Work-life balance is important because it is strongly related to identity. Recently, the introduction of the mobile office system has emerged as a way to solve the problem of work-life balance. It is based on the teleworking which was formerly generated. Teleworking is to perform the work in the employee's home or office space set aside without going into the workplace. Concept of the mobile office system here is not only using portable devices during work for convenience but also the system which is designed for the performance. Thanks to the diffusion of smart devices(smart phone, tablet pc), mobile office system has been spread. Although the importance of mobile office systems is emerging, there are few researches about it. Even they mostly focus on the standpoint of performance of mobile office system. However, Quality of life is as important as the performance. As a part of Quality of Life field, Work-life balance is the closest to employee's quality of life. So this study aims to examine the effect of the use of mobile office systems on work-life balance. To do so, we try to find factors effecting Work-life balance from existing studies and then set a research model. We set the use of mobile office systems as independent variables which are divided by use of function, use by location and use by situation. There are four dependent variables - sense of self command, sense of balance, solving work problem, solving life problem. We collected data from employees who are using mobile office systems on their job. 215 people were participated in the survey and we used multiple regression analysis to verify our research model. Results show that every independent variable has no impact on solving work problem while they have slight impact on the other dependent variables. Especially use on the business trip has significant effect on dependent variables. It means that there is a possibility use of mobile office system could control the employee's quality of life and system should be evolved until it covers even critical tasks. Also, support for mobile office system -education, encouragement-should be provided. By mobile office system is maturing, future research would be done.

In this thesis using FTA technique, the author proposes a new method of analysis of some accidents in construction work. Some efficient plans of safe facility investment are made out. For this study, I referred to 'The Death Accident in Construction Works', which have been published by Korea Industrial Safety Corporation from 1993 to 1999 for 6 years. I selected some of apartment constructions which have caused many deaths for the purpose of analysis in the study. I found that the concrete work using ferro-deck takes more deaths than the conventional construction. After finding this, I selected GANG FORM works using ferro-concrete which is the most widely used but causes many accidents. On the basis of the classification, I try to do some quantitative analyses by adding the death frequency and material factors. In order to draw up the most efficient investment plan, it is imperative that FT diagram be made out and that factors. In order to draw up the most efficient investment plan, it is imperative that FT diagram be made out and that minimal Cut Set be needed. It requires a great deal to labor and time to get Minimal Cut Set. The Minimal Cut Set which is formed of these process is the main factor to analyze disaster in the work. It is desirable that we add calculated percentage of accidents to these factors to these factors in value order, that is to say, from the high cost to low cost.

The set of root classes plays a crucial role in the Nielsen root theory. Extending Brown et al.'s work on the set of root classes of iterates of maps, we rearrange it into the reduced orbit set and show that under suitable hypotheses, any reduced orbit has the full depth property as in the Nielsen type theory of periodic orbits.

The purpose of this study is to investigate the relationship between work-family conflict and job-life satisfaction of married female workers. Two data sets were used in this study. Both data sets were gathered from structured questionnaires and time dairies. The first data set was collected from 370 married female production workers in 1995 and the second set was collected from 143 married female clerical workers in 1996. Job and life satisfaction were measured on 5-point Likert scale where 5= very unsatisfied and 5= very satisfied. The overact means for both groups were 2.97, 3.09 for job and life satisfaction respectively The findings of this study are; 1) Clerical workers have significantely higher job and life satisfaction than production workers. 2) Multivariate analysis reveal that work-family conflict is negatively related to job satisfaction while income is positively related to job satisfaction. 3) In the path analysis model, work-family conflict has a negative direct effect and indirect negative effect mediated through job satisfaction on life satisfaction. Job satisfaction and husband's division of housework have a positive direct effect on life satisfaction. However, total labor time has a negative indirect effect mediated through work-family conflict on life satisfaction and income huts a positive indirect effect mediated through job satisfaction on life satisfaction.
