도시의 많은 교량 구조물은 내구연한 및 노후 상태에 따라 외형적 변형이 발생하고, 지진과 태풍 등은 노후 시설물의 변형을 더욱 악화시키고 있다. 불규칙하고 미세한 점진적 외형 변형은 육안으로 확인하기 어렵고, 시설물의 성능을 저하시키게 된다. 따라서 최근에 교량 구조물의 이상 거동을 실시간의 무선 방식으로 검지하는 기술이 연구되고 있다. 본 연구는 자이로스코프를 이용하여 구조물의 미소한 물리적 변화량을 실시간으로 측정하는 변위측정모듈을 개발하였다. 개발된 계측 모듈의 성능은 시뮬레이션 실험을 통해 검증하였다.

The interest in decrepitude expanded by graying is gradually growing in modern society. Moreover, he concern over decrepitude along with healthy mind and body is increasing. Therefore, there are many concerns and efforts toward physical and mental health. In addition, the interest in and effort for appearance health and value is rising as well as physical and mind health. The middle age is the most stable age based on the economic and social status that had been achieved through the life, but it is the most stressful age due to physical health problem and appearance ageing. There are many advanced studies for self-esteem and life satisfaction in old age by using hair, skin-care, cosmetic, nail-art among beauty related fields but studies on self-esteem and perception of successful ageing through user satisfaction of beauty service is lacking. This study is aiming to verify empirically the positive effect of self-esteem improvement through user satisfaction of beauty service on perception of successful ageing for middle-aged over 50 years old. The study has assumed that the higher middle-aged's satisfaction of beauty service is, the more self-esteem improves and there has a mediated effect to contribute successful ageing.

Agricultural water occupies the largest portion of total water use in Korea, and generally researches on the development of agricultural water have been stressed on the demand of agricultural water itself. But it is unavoidable to change a policy from the development of water resources to cope with the increase of water demand to the effective management of existing water resources. Evaluation of the decrepitude of irrigation facilities and their reasonable maintenance are important for the effective supply and use of agricultural water. Therefore it is necessary to develop evaluation technique that diagnoses the current condition of irrigation canals and suggest a countermeasure to improve the found problems. 25 items in 6 classes were selected for the evaluation of irrigation canal systems, and the weighted value between the items was calculated using AHP (Analysis Hierarchy Process) method. The current condition of the irrigation facilities was evaluated from the class evaluation marks, and ranking was decided from the total marks between the projects, and finally the priority of the project for the improvement was given.

This study started from my concern over maintenance and renewal of existing buildings and other seriously damaged Modern Architecture under the urban development. Above all, we must face up to reality of an increasing need of renovation of old buildings that are in its physical, social, and economical decrepitude. Currently, 25% of total buildings come under renovation period within 20 years, which means that we do not have enough time to decide the destiny of old buildings. In the city, there has been endless controversy over conversation and development. Recently the Cultural property Registration System made it possible a positive usage of non-designated cultural property with historical value. This very useful system renewed our perception on Modern Architecture as cultural property and also triggered peoples' interest in recreating new value beyond economical one. So we really need a balanced view that can bring into both growth of contemporary city and renewal use of Modern Architecture. Here, in this study I tried to solve that problem with Conversion Design and define what a realistic design way for them is. To get more reasonable result, I chose a factor analysis for 20 conversion projects in Japanese Modern Architecture. Conversion Design is a proper way to restore the identity of old buildings and the most effective way to sustainable use of Modern Architecture.

최근, 지하수 양수량이 적은 관정을 대상으로 양수량을 증가시키기 위한 연구가 활발하게 이루어지고 있다. 이러한 관정에 대한 효율적인 방법으로는 공압파쇄를 이용할 수 있다. 공압파쇄는 관정 내 일시적 및 단계적으로 공기압을 주입하여 암반 내 응력의 불균형을 초래시켜 균열의 폭, 길이, 수를 증가시키거나 균열 내 물질을 제거함으로써 지하수가 유입될 수 있는 공간을 확보해주는 공법이다. 즉, 일시적으로 큰 공기압을 암반 내로 주입하여 암반 원래의 투수성보다 더 높은 투수성 및 지하수양을 얻을 수 있다. 이 연구의 결과로서 P-5공에서는 파쇄 전 양수량이 $26\textrm{m}^3/day$, 수위강하량이 51.12m, 비양수량은 $0.51\textrm{m}^2/day$이며, 파쇄 후 양수량은 $30\textrm{m}^3/day$, 수위강하량이 56.58m, 비양수량은 $0.53$m^2$/day$이다. 이는 당초보다 $4\textrm{m}^3/day$이 증가되었으며 약 15%의 수량증대 효과가 나타났다.

Urban style row-rise houses for rent have been supplied to the center of city from the 1950's first half The amount of stock is about 450,000 houses and occupies about 40％ in the private rented house. As for the structure, the 60％ of them is wooden-structure and the rest is non-wooden. Stocks of 57.5％ of the wooden-structure and 86％ of the non-wooden were built after 1981 years. It was 1981 years that the new earthquake-resistant standard was carried out, the improvement of stocks built before 1981 is necessary because those don't satisfy the present standard. To investigate the renovation possibility of urban style row-rise houses for rent, actual situation of two-story apartment at 2,4, and 5 Chome Taito-Ku in Tokyo was surveyed from July to November 2001. The number of building analyzed is 227 ridges among 234 ridges of the surveyed two-story building. 90％ of building analyzed is wooden structure. 1) The site of 88％ building surveyed is close to a road less than 4m width. It becomes the existing non-conformed building in the building construction act. It is impossible to make a renovation such as rebuilding, extension and remodeling because it requires the set back when renovating this type of non-conformed building, 2) The building built before 1981 is almost wooden-structure, and occupies 37％ of the building surveyed, and doesn't satisfy the present earthquake-resistant standard. An improvement of them is needed because the decrepitude of building proceeds. 3) 50％ of openings and 40％ of windows of the building surveyed doesn't use noncombustible materials. Though it becomes the existing non-conformed building, it can satisfy the present standard by replacing openings with noncombustible materials.

This study attempts to suggest a standard for maintenance and repair cost per each unit area, by analyzing the causes and cost of various maintenance and repair work in the university facilities. The result of my study on the data of maintenance and repair work for 12 years between 1990 and 2001 in the two campuses of the university that I selected for my case study is the following. (1) The yearly average for maintenance and repair cost in the facilities of the university with 67 old and new buildings for the past 12 years was $W4,422/m^2$. In addition, the repair cost based on the calculation of the degree of decrepitude of the buildings was $W10,291/m^2$. (2) The number of causes of maintenance and repair work increase steadily every year, due to the development of universities and changes in the educational environment. A special case like a university merger also appears, which also demands maintenance and repair work of university facilities. (3) It is important that a budget for interior maintenance is increased or added to an extent, in order to minimize the maintenance and repair cost of the university facilities, and to cope with changing educational environments flexibly. (4) The publication of a white paper that includes the planning of a building, construction process, and changes in design, seems to be required for the sake of users' convenience and efficient maintenance and repair work.
