소양강댐 유역의 비점원 오염 포텐셜을 평가하기 위하여 LTHIA/NPS, RUSLE그리고 ArcView GIS 모델을 사용하였다. NPS 오염 포텐셜(VI)계산은 강우유출(RI), 토양유실(EI), 농약사용량(CI), 가축분뇨(LI)와 상업용 비료(FI) 사용량을 대표하는 지수(Index)를 사용하였다. 유역의 유출심은 4.9에서 34.3cm였으며, 토양유실량은 0.25에서 802 ton/ha/year 범위로 평균은 6.46ton/ha/year이었다.

During braking at a train, thermal energy is generated due to the frictions between disk and lining and wheel and shoe. In general, the braking transfers the kinetic energy into thermal energy. Therefore, the frictional characteristics are varied according to the braking force, the thermal resistance, and the thermostable, etc. Using a Dynamo testing we have studied the frictional characteristics and the thermal distribution to investigate a stable speed and to improve the testing method through comparing and analysing in the measurement of the thermocouple temperature and infrared camera.

This study is to develop a Fe-based disc brake lining with sponge structure for rolling stock of 150㎞/h train and to concept design with 3 groove type for brake disc reducing hot hair-crack and certainly friction coefficient. The developing brake lining would be to presumption of saving 300 million won during one year.

It is vary importance that stopping distance for the freight train and need to design parameter of the brake force and friction coefficient. Acoording to the brake force between shoe and wheel less than the adhesion between wheel and rail. Because of vary difference between empty and weight car of 0~500kN, this solution was made to application for variable loaded brake system When the V=110㎞/h, the emergency stopping distance of freight train is about 700m, so this study was considered on the two condition, one of the increse brake force and to be different of the increse friction coeifficient on the brake shoe. It was usefull increse friction coeifficient Result of study, analyze effect of the brake shoe on the brake force of the freight car and high friction coefficient were proposed. To do this, μ=0.155±10% when S=600m on the V=110㎞/h of the train, 2 groove of friction surface on the temperature distribution were considered
