  • En case of the fatigue life evaluation of rolling stock structures, mainly deterministic fatigue life evaluation has been carried out. But most of the parameters influencing on the fatigue life have a probabilistic distribution such as normal, log-normal, Weibull, etc. Therefore, to take probabilistic factors into fatigue life evaluation, probabilistic methods are being applied to the fatigue life evaluation of rolling stock. In this paper, probabilistic S-N analysis and methods using limit state functions are introduced. And some results of fatigue life evaluation obtained with these methods for rolling stock structures are shown.

  • The aim of this study is to propose the reasonable method of evaluation on the value of the life-time household work. for homemaker claim her share in the matrimonial property in relation to her life-time household work and to provide the basic data to measuring proper compensation for homemaker and calculating of the donation tax and inheritance tax amount. Tom compare the difference of the method of evaluation on the value of the life-time household work is evaluted by three methods: the model of the life-time household work which is reflected major variables in the FLC frame work marital stage, total marital period. The major findings are as follows: 1) Among the three evaluation me? The method of Total marital period is evaluatied the lowest value of the life-time household work. 2) The evaluation method of marital stage is more resonable method than the method of total marital period habe a convenience of evaluation but it dos'nt reflected major variables which influence the value of life-time household work. 3) the most resonable method of evaluation on the value of the life-time household work is revealed the model of the life-time household work which is reflected major variables in the FLC frame work the age of first and last offspring marital period.

  • The aim of this study is to propose the criteria for a evaluation model of the lifetime household work and organize the model. The results were as follows: Three criteria for a evaluation model of the life-time household work were proposed. $\circled1$ An appropriate framework of the evaluation model should be based on the transition of the family life. $\circled2$ The model should include major variables influencing the value of household work of homemaker. $\circled3$ The model should be flexible enough to accommodate various evaluation methods, and should reflect idiosyncracies of different evaluation methods. In view of the criteria stated above, the present study is based on the family life cycle framework. And the age of the last offspring exhibits a consistent major influence in the evaluation based on the household work hours, while the education level of homemakers shows a consistent major influence in the evaluation based on household worker. So as to reflect these two major variables in the family life cycle framework.

  • The purpose of this study was to analyze the characteristics of the factor structure in Clothing Silhouette Image and the differences of Image Evaluation related to Grouping of Line and Grouping of Body Emphasis using Silhouette Image Factor and Life Space as variables. Clothing Silhouette Image was estimated by the photographs of 9 Life Spaces ${\times}$ 23 Clothing Silhouettes with 15 semantic differentiated by-polar scales. The major finding were : The factor structure of Clothing Silhouette Image were found to include 4 factor dimensions-Capability Evaluation, Function, Activity. It was clear that Silhouette Image were affected by Life Spaces. There were the differences of Image Evaluation related to Grouping of Line and Grouping of Body Emphasis. There were the differences of Life Space Evaluation related to Grouping of Line and Grouping of Body Emphasis. Therefore it is important to considerate Life Space for selecting Clothing Silhouette.

  • Family professionals and family program staff need to consider the importance of program evaluation in Korea since an increasing number of Healthy Family Support Centers are providing diverse intervention and education programs. The purpose of this research paper is to (a) introduce a program evaluation model that includes the program life cycle; (b) help family professionals and family program staff understand the link between program implementation and evaluation processes; and (c) facilitate discussions in terms of program evaluation of Healthy Family Support Centers and evaluation roles of different levels of Healthy Family Support Centers including the headquarters, regional, and local centers. Understanding the program life cycle and relevant evaluation processes will help family professionals and family program staff be more strategic in answering critical questions about a program's effectiveness. The benefits of program evaluation and its implications are discussed.

  • 본 연구의 목적은 자기연민과 삶의 만족의 관계에서 사회에 대한 인식과 자신에 대한 평가의 매개효과를 보는 것이다. 이를 위해 자기연민척도와 삶의 만족도 척도를 사회적 안녕감과 핵심자기평가와 함께 직장인 215명에게 실시하였다. 연구결과, 사회적 안녕감과 핵심자기평가는 자기연민과 삶의 만족도 간의 관계를 완전 매개 하였고, 사회적 안녕감과 핵심자기평가의 간접효과 간의 차이는 유의하지 않았다. 이러한 결과는 자기연민이 삶의 만족도를 개선하는 효과가 사회적 안녕감과 핵심자기평가를 통해 설명될 수 있음을 보여준다. 추후 연구를 위한 본 연구의 시사점과 제한점에 대해 논의하였다.

  • Over the last several years, Korea has increasingly adopted design-build for public construction projects. There is a much greater awareness of the need to change to a system based on 'Value for Money', which is high on the government's agenda. A whole life performance bid evaluation model is proposed to aid decision makers in the selection of a design-builder. This is based on the integration of a framework using an analytic hierarchy process, as the bid awarding system is being changed from one based on the lowest price to one based on best value over the life-cycle. Key criteria such as whole life cost, service life planning and design quality are important through the key stages of the evaluation process. The model uses a systematic and holistic approach, which enables the public sector client to make better decisions in design-builder selection, which will deliver whole life benefits based on long-term cost-effectiveness.

  • In order to ensure the construction of sustainable reinforced concrete structures, durability evaluation of RC structures before construction should be carried out. In this paper, a service life evaluation technique using a safety factor determined by a reliability theory for RC structures subjected to chloride attack is proposed. The life safety factor and the service life evaluation .proposed in this paper can be applied consistently for the durability evaluation of recently developed Korean standard specification for durability of concrete structures which be used effectively for the evaluation before construction and maintenance for RC structures under chloride attack.

  • The purpose of this study is to find the differences between the husband's and wife's satisfaction of home life. This study is also to compare and analyze some empirical influence on life satisfaction of husband and wife according to home socio-demographic variables and subjective evaluation of economic level including their perception levels of home economics circumstance. The major results are as follows; 1. The husband's score of life satisfaction shows signifcantly more than wife's score that is his score is 3.36 and her score is 3.19. 2. The variables which affect couple's life satisfaction are the perception of resource adequacy the perception of the adequacy of household income, the evaluation level of resource contribution and the perception of level of living relative to others. The most influential variable of the husband is the perception of resource adequacy, while the most influential variable of the sife is the evaluation level of resource contribution. 3. The result of the relative contribution for the variables of life satisfaction are as follows. The explanation of husband's sociodemographic variable is 11.5% if variable of subjective evaluation of economic level is added the explain power is 34.1%(increase, 22.6% (p<0.001)) The explanation of wife's socio-demographic variable is 9.8% If variable of subjective evaluation of economic level is added the explanation is 41.2% (increase 31.4% (p<0.001)).
