The study attempts to explore factors which affect life satisfaction of the elderly, and thereby to identify the most efficient strategy to enhance their happiness and satisfaction with life by means of a family support system. Previous research suggests that the family is the main origin from which emotional and ecionomic satisfacton of the aged evolves, and satisfaction is facilitated by societal assistance for the family to financially support old persons. These theoretical antecedents are incorporated into a causal model for empirical verificatio. To this end, interviews were conducted in Seoul with 300 individuals who are 60 years old or over. The major findings of this study support the theoretical assertions of previous studies. They are summarized as follows : 1. Family solidarity is highly correlated with life satisfaction of the elderly. 2. Family solidarity is raised by the intensity of their social association, satisfaction with housing, and financial resources. 3. Eduation, income and marital status as exogenous variables do not directly affect life satisfaction and family solidarity, despite their strong overall correlation. Casual effects of each variable are linked to family solidarity and then to life satisfaction through a family support system for the elderly.

Life cycle costing is one of the most effective cost approaches when we choose a solution from series of alternative so the least long-term cost ownership is achieved. Life cycle costing in railway industry has been focused on the prediction of investment for railway vehicles. But in today, the life cycle cost, LCC, prediction on the aspect of operation and maintenance cost through whole life cycle is highly necessary. In this paper, we present a strategy for the development of life cycle cost estimation software on the aspect of maintenance strategies of railway vehicle. For this purpose, we suggested a structure of LCC software based on the UNIFE LCC model. And we developed a pilot version of software to evaluate the LCC model that we suggested for railway vehicle. We performed LCC analysis on the brake module of metro vehicle in case study and concluded that the software and model developed in this research could enough to support engineers in choosing better cost effective solutions from many alternatives.

The study explored the work-life balance of three dual-earning couples using the household economics approach according to the hermeneutics paradigm. Three families were analysed. The couples were interviewed individually with a non-structural interview guide about their work history and life history, and with a semi-structured interview and structured questionnaire about their work hours, childcare practice, husband-wife relation, household income and expenditure, and daily and weekly schedule. The results revealed the different paths and various strategies to adjust work-life balance among the cases. Strategies were discussed to facilitate changes in labor market policy, childcare policy, working place culture and family's daily life planning.

This report is the result of interim evaluation of a health promotion project which was operated by a public health center of K Gu in the year of 2000. It evaluated the aspects of the aim of a project, a target group. and adequacy and appropriateness of a approaching strategy by considering data of public health center's self-evaluation, and guidelines of a group assigned to evaluate the project. The way of evaluation was dividing the project into a colligated evaluation and a evaluation by projects in the aspects of the structure, the procedure. and the result of a result. Through this. a device to improve the health improvement project was derived. The target data for evaluation was the second data and data of self-evaluation, reported data, membership register data of a health management. and interview materials with the people in charge by projects that are all collected as a project management documents. The result of evaluation is stated below. 1. Main purpose of a health promotion project is building a environment of healthy life practicing and providing information through various ways to increase the rate of practicing healthy life. Through overall project. the ultimate purpose and definite purpose were same, however, it was not quite satisfied to offer planning of a time, and a target amount in detailed strategy. As the purpose was to build environment of healthy life practicing. most of the projects had the whole community citizen as a target group. That made difficult to operate detailed projects. so the result was hard to estimate as much as the effort put into it. Also, there were too many kinds of projects and target groups to be equal to by the human source of a health promotion project team. so we were just bent on operating a project. and could not prepare for the evaluation. As the most of former evaluation of public health service was just counting number of the objects, the new way of evaluating a project wasn't familiar to us. so the evaluation of a detailed project cannot be done well. Techniques and advices needed for all of these things weren't offered appropriately. For the forward direction of unfolding project. it is desirable to operate project by selecting focused target and considering a strategy of evaluation as a strategy of reasonable spread. The evaluation of the project became difficult as participation of citizen for it was poor. So, approach strategy that can lead the motivation of community citizen should be derived. 2. For the continuation of a health promotion project, technical assistance system. description of a field in charge, and arrangement of the amount of task should be developed as a central level. Furthermore, as the health promotion project focus on behavioral modification program whose purpose is to lessen dangerous factors. the public health service model which is incorporated with former project should be developed and spread out in the field for the object-centered project plan.

The sample of this study consisted of 140 informal caregivers who provided care to the older adults(over 60 years of age) in Great Cleveland, USA. Self-rated questionnaires were utilized to collect information. The purpose of the study was to identify coping strategies most frequently utilized by informal caregivers of older adults and to examine predictors of the caregivers' health responses to the caregiving situation applying Lazarus and Folkman stress model(1984). Stepwise multiple regression was used to identify significant predictors among caregivers' demographic-socio-economic factors, older adult's dependency of activities of daily living(ADLs), caregiver's appraisal to the caregiving situation, and coping strategies. Informal caregivers (N=140) included in the study utilized help-seeking and problem-solving coping strategies more than self-blame and minimization of threat coping strategies. Caregivers' responses to the caregiving situation were observed by caregivers' perceived physical health, depression and life satisfaction. For perceived physical health, threat appraisal, older adult's dependency on ADLs, existential growth coping strategy, and monthly income accounted for 25% of the variance. Caregivers who appraised the caregiving situation as more threatening, reported higher dependency on ADLs, used more existential growth coping strategy, and had higher monthly income reported better physical health. For depression, threat appraisal, stress appraisal, existential growth coping strategy, self-blame coping strategy, and monthly income accounted for 48% of the variance. Caregivers who used more existential growth coping and less self-blame coping, appraised the situation as less threatening, less stressful, and had higher monthly income reported less depression. For life satisfaction, self-blame coping, existential growth coping, monthly income, stress appraisal accounted for 49% of the variance. Caregivers who used more existential growth coping, less self-blame coping, less stress appraisal, lower monthly income reported better life satisfaction. In conclusion, informal caregivers in this study utilized positive coping strategies such as problem-focused, existential growth, help-seeking, rather than negative coping strategies including self-blame. When they utilized positive coping strategies more often, caregivers experienced higher perceived physical health, higher life satisfaction and lower depression. Therefore, nursing intervention which utilized positive coping strategies is needed to enhance informal caregivers to have positive health responses to the caregiving demands.

In this paper, a new single phase voltage sag/swell compensator using direct power conversion is proposed. A new compensator consists of input/output filter, series transformer and direct ac-ac converter, which is a single-phase back-to-back PWM converter without dc-link capacitors. Advantages of the proposed compensator include: simple power circuit by eliminating dc link electrolytic capacitors and thereby, improved reliability and increased life time of the entire compensator; simple PWM strategy or compensating voltage sag/swell at the same time and reduced switching losses in the ac-ac converter. Further, the proposed scheme is able to adopt simple switch commutation method without requiring complex four-step commutation method that is commonly employed in the direct power conversion. Simulation and experimental results are shown to demonstrate the advantages of the new compensator and PWM strategy. A 220V, 3kVA single-phase compensator based on the digital signal processor controller is built and tested.

As mobile Technology came into people's everyday life the conflicts between users' expectation on the mobile technology and real performance has increased. These kind of conflict as far as technology concerned, are called 'technology paradox' and have been studied by few researchers. The discussion on mobile technology paradox could be critical to understand users' mobile technology usage behavior because when users perceive the paradox they are supposed to choose a coping strategy. another factor regarding the perception of paradox and coping strategy the culture should be considered. Thus this paper developed a measurement for mobile technology perception and empirically tested based on survey result from Korea and U.S.A. The analysis clearly shows that there are substantial differences in perceiving technology paradox and choosing the coping strategy between Korean users and American users.

BIM could be used for integrating project information through life cycle of building facilities. Also it could improve the accuracy and work efficiency through data interoperability with other disciplines. However, these benefits from adopting BIM could not be attained easily in real project cases. In order to make the most use of BIM and get the maximum benefits from it, the environments such as standards, guidelines and the related technologies are also could be supported. Therefore many countries are developing or already developed the technology roadmap for BIM. In this study, we tried to analyze the BIM technology status and develop the strategy for improve usability of BIM in Korea.
