이 연구에서는 점탄성감쇠기가 설치된 구조시스템의 통합최적설계 방법을 제시하였다. 최적화를 위한 목적함수로는 구조시스템이 유발하는 사회적 비용을 의미하는 총 생애주기비용을 사용함으로써, 구조제어 시스템의 성능에 기반한 경제적 유익을 극대화하도록 하였다. 구조물의 층별 기둥 강성 및 점탄성감쇠기의 사용량 등을 설계변수로 하여 생애주기비용함수를 정의하였으며, 통합시스템을 동시에 최적화하기위한 방법으로 유전자 알고리즘을 적용하였다. 동일한 초기비용을 사용하며 통합최적설계를 수행하지 않은 설계를 통해 얻어진 지진응답과 비교한 결과, 제안하는 통합 설계방법은 보다 우수한 진동제어효과를 발휘하는 것으로 나타났다.

In this paper, the system reliability concept was presented to predict the lifespan of bridges. Lifetime distribution functions (survivor functions) were used to model real bridges to predict their remaining life. Using the system reliability concept and lifetime distribution functions (survivor functions), a program called LIFETIME was developed. The survivor functions give the reliability of component at time t. The program was applied to an existing Colorado state highway bridge to predict the failure probability of the time-dependent system. The bridge was modeled as a system, with failure probability computed using time-dependent deteriorating models.

The purpose of this study is to examine the level of social integration of the person with physical disabilities based on independent living paradigm according to life span and to find factors affecting social integration and therefore to make policy implications for a better rehabilitation system. The data was obtained through telephone interviews with physically disabled residing in the city of Seoul and the suburb area of the city. The final sample consists of 591 respondents. The data was analyzed through frequency, oneway anova, pearson's correlation analysis, and multiple regression. In this study, social integration based on independent living paradigm was divided into separate but related dimensions: autonomy of activity daily living, accessibility, economic level, degree of social support satisfaction, consumer control, psychological empowerment. The major findings of this study were as follows: First, the levels of six dimensions of social integration based on independent living paradigm were very different and especially the level of dimensions such as degree of social support satisfaction and consumer control were lower than other dimensions of social integration. Second, each level of social integration by life span was very different. Finally, the factors affecting social integration were socio-psychological traits such as social support, rehabilitation services, self esteem and acceptance of disability as well as the attribution to disability. The current findings suggest that improving nay only ADL or accessibility but also consumer control or social support should be considered by professional and policy makers. And differentiated intervention and policy according to life span necessary to policy makers and field practitioners.

This qualitative study explored a middle-aged lesbian's life and her identities by the oral life history approach in feminist epistemology, where the participant is not the object but the subject of knowledge. The participant kept her own perspective that her homosexuality was not intrinsic but constructed. In her life's history, she was a "docile body" accepting socially constructed historical meaning of homosexuality, as well as a "resistant body" protesting against social discrimination and oppression for homosexual population. She overcame an embedded negative recognition of her scaled injured body and her sexuality as "deficient". Finally, she showed an amazing resilience and an indomitable spirit for reconstructing the meaning of her body as "blessed." Beyond the deficient body, as an active agent not the pathologic sexual minority, she could cultivate compassion and empathy for others. From the results, it is important how to place gender and sexuality in the context of social work theory and practice. Sexuality, not sexual orientation, is 'our' collective agenda to address the social problems which were associated with social hierarchy, inequality, and injustice.

In the resent years, the importance of VE (value engineering) and LCC (life cycle cost) analysis for apartment building construction projects has been fully recognized. Accordingly theoretical models, guidelines, and supporting software systems were developed for the value engineering and life cycle cost analysis for construction management including large building systems. However, the level of consensus on VE and LCC analysis results is still low due to the lack of reliable data on maintenance. This paper presents time dependent LCC model based value analysis method for rational investment decision making and design alternative selection for construction of apartment building. The proposed method incorporates a time dependent LCC model and a performance evaluation technique by fuzzy logic theory to properly handle the uncertainties associated with statistics data and to analyze the value of alternatives more rationally. The presented time dependent VE and LCC analysis procedure were applied to a real world project, and this case study is discussed in the paper. The model and the procedure presented in this study can greatly contribute to design value engineering alternative selection, the estimation of the life cycle cost, and the allocation of budget for apartment building construction projects.
