구조물의 경제성 분석은 그 프로젝트의 실행을 결정할 수 있는 중요한 요소이다. 본 논문에서는 대공간구조물의 경제성 분석을 위하여 기존에 건설된 대공간 구조물(제주 월드컵 경기장)의 건설비용을 분석하여 경제성 분석 모델의 구축을 위한 기초 자료를 제공하고자 하였다. An economic analysis is one of the most important factor to determine tile project feasibility. In some mega project, however, it is not unique factor to make a Go or No-Go decision because of overriding this work, an economic aspect by some project indirect factor such as political, social, environmental and technical factor, etc. The purpose of the this study is to investigate the cost model effects of spatial structure.

Pressure loads caused by gas, water and wind are the most important load cases in structural analysis. Often the pressure loads are approximated by constant directional loads since it is difficult to evaluate the exact value. However, the pressure load is defined as a displacement dependent one and it is necessary to consider the follower effects of the load in analysis procedure. In this study, the large deformation analysis considering geometrical nonlinearity for shell structures under pressure loads is presented. Finite element by using a three-node flat triangular shell element is formulated and the follower effects of the pressure load are included in the formulation. Some of results are presented for cantilevered beam under uniform external pressure and thin circular ring under non-uniform external pressure. The present results are in good agreement with the results available in existing literature and commercial software ABAQUS.

In this work, a finite element model is presented for geometrically non-linear analysis of shell structures. Finite element by using a three-node flat triangular shell element is formulated. The non-linear incremental equilibrium equations are formulated by using an updated Lagrangian formulation and the solutions are obtained with the incremental/iterative Newton-Raphson method and arc length method. Some of results are presented for shell structures. The obtained results are in good agreement with the results available in existing literature.

The aim of the research is to propose a design framework of Building Management Systems (BMS) using IFC-BIM. IFC mainly deals with geometric information at architectural design stage but there are rare efforts to bridge the gap among stakeholder through the building life cycle. To date, research on sensor related data format such as IfcSensor entity is in its early stage, there is scarce knowledge. Patch & Implant technologies based on wireless sensors and sensor network can lead to the efficient Facility Management (FM), which can help reduce the greenhouse gases practically. The research steps are as follows; firstly, theoretical aspects of smart building and its environmental perspective are discussed. Context sensitive maintenance method is chosen and detailed explanation on the components of the system such as context awareness, building information modeling, web service, and mobile devices are follows. Thirdly, by analyzing relevant IFC entities, its applicability to BMS in mobile environment based on web service is sought. Data management work flow for Wireless BAS is introduced at the end.

본 연구는 효과적인 복부관리를 위하여 스톤테라피가 비만청소년의 체성분과 허리둘레에 미치는 효과를 검증하고자 BMI가 25이상인 청소년을 대상으로 실험군 7명과 대조군 7명으로 나누어서 1회 30분, 주3회, 8주 동안 스톤테라피를 실시하고 난 후에 허리둘레와 체성분검사를 실시하였다. 그 결과, 실험대상자들의 실험전, 후 차이를 비교해보면 체중, BMI, 체지방량, WHR, 허리둘레가 감소하였고, 골격근량이 증가한 것으로 나타났고, 두 집단 간의 허리둘레, WHR, 체지방량에서 통계적으로 유의미한 감소효과가 있었다. 또한 스톤테라피 관리 후에 살도 빠졌고 뱃속도 편하며, 배변도 좋아짐으로써 만족하고 있다고 대다수가 응답함으로써 스톤테라피가 체중감소에 긍정적인 영향을 미친다는 것을 알 수 있었다. The purpose of this research is to verify the effects of stone therapy upon reduction in adolescents' body composition and waist circumference. Targets of this research were 25 with BMI more than 25. They were divided into 2 groups. 7 people were treated by stone therapy as a experimental group. 7 people were for the control group without execution of abdominal management. All of them were not restricted to exercise or eat. The stone therapy was carried out for 30 minutes per once and 3 times a week for 8 weeks. After then, body composition test and waist circumferencewere was measured. The results are as following. The experimental group showed the reduction in weight, BMI, waist circumference, WHR, body fat amount in comparison with control group in terms of statistical significance. The results means that stone therapy would be conducive in alleviating abnormal body composition and in reducing obeisity.
