최근 도시지역의 수해요인은 내수침수불량에 기인하기 때문에 유수지 및 배수펌프장을 신설하여 유수지로 유입되는 유출량을 하천으로 강제배수하게 된다. 그러나 하수관거의 용량이 부족하여 유수지로 미처 유입되기 전에 하수관거의 역류로 침수피해가 자주 발생하고 있다. 따라서 본 연구에서는 도시 내배수 체계의 조사방법을 제시, 하수관거의 위험도를 평가하고 개선할 수 있는 방안을 제시하였다. 또한 배수펌프의 가동대수를 단순한 수위기준에서 변화시켜 실무에서 전문가가 아니더라도 사용할 수 있는 전산모형 8개를 개발하여 제시하였고, 지속기간, 설계빈도, 시간분포 등을 변화시켜 유수지 수위의 적정 조절여부를 검토하였다. 그리고 강제적인 배수에 의해 하류부의 수위영향이 예견되기 때문에 해당 유역의 수위를 안전하게 유지하면서도 하류부에 수위영향을 최소화할 수 있는 방안에 대해서도 검토하였다. 연구결과 Fuzzy 모형이 기존의 운영방법보다 더 효과적으로 유수지의 수위를 저하시킬 수 있었으며, 하류부 수위는 약 8cm 정도 감소시킬 수 있었다. Urban flood damage has been caused by drainage deficiency. One of the methods to solve this problem is to construct detention basin and Pumping station and to pump out the water to the river. However, because of rapid urbanization, the capacity of drainage pipelines is sometimes not sufficient enough during the rainy season. Therefore, even though we have enough pumping stations, the inflow of surface water never reaches to the detention area, causing floods in urban area. This research is to find improvement of urban drainage system, estimating drainage pipeline risk. Also, eight models for a computer program were developed for practical use. The models were verified changing precipitation duration, intensity, design period, time distribution model, and etc. This verification was processed focusing that the model can regulate the water level in the detention basin and minimize the effect downstream. As a result Fuzzy models were found to be efficient to lower the water level in detention basin, and decreased about 8 cm in water level of downstream.

The purpose of this study was to provide basic materials available to establish the recognition of dance sport on status of dance sport as sport for all. For this purpose, this study used the questionnaire research so as to investigate how middle-aged were conscious of dance sport and the level of their participation in dance sport. In conducting the questionnaire research, questionnaires were distributed to 456 middle-aged in Seoul and Kyonggi Province. Based on the study results, the following conclusion was drawn : First, Cognition of the dance sport of those middle-aged women who are currently receiving dance sport training represents for the most part a high response. When viewed from varied social aspects, magazines or books of dance sport are deemed to be short of, and instead cultivation of specialists related to it is considered a prerequisite. And the notion that general cognition of dance sport came enhanced today than in the past might be ascribed to the fact that dance sport was recently taken as an exhibition game at the Sydney Olympics. Second, cognition of the effects and values of dance sport of those middle-aged women who take part in dance sport reflects a positive response on the whole. Their perception indicates that dance sport is conducive to the maintenance and promotion of health. Furthermore, they think that dance sport contributes to the development of culture and simultaneously is of much help to relieving stress, along with the notion that it is one of the most necessary leisure activities in contemporary society. Third, as a result of having analysed participation into and preference for dance sport of those middle-aged women who take part in dance sport, they do not lapse much time for it, and their dance sport techniques are thought not to be so good by their own evaluation. This is presumed to be caused by so little time spent for it, and their preference covers dance sport of varied genre musics. Fourth, those middle-aged women who take part in dance sport disclose a very good response on dance sport socialists.
