This study is to investigate the micro hydropower by discharge water of Jeju sewage treatment plant located in Jeju city and Dongbu sewage treatment plant located in Seogwipo city, Jejudo. The flow rate is applied at 1.11 ㎡ /sec in Jeju and 0.157㎡/sec in Dongbu, which are the average 95 day flow rates for the recent 3 years. The net head is 5.21m in Jeju and 12.41m in Dongbu which are hight between discharge flow chamber and the location of hydraulic turbine installation. Therefore, the quantity of electric power generation is estimated to be 42.97kW in Jeju and 14.6kW in Dongbu. The monthly quantity of electric generation is 28.23MW in Jeju and 9.46MW in Dongbu. Also the yearly quantity of electric generation is 338.7MW in Jeju and 113.53MW in Dongbu. The type of hydraulic turbine recommends a crossflow or a tubular in Jeju and an inline-type hydraulic turbine in Dongbu.

Jeju-do highly relies on outside sources of energy because of its geographical situation. Recently, it has been necessary to enhance its stable energy sources there by protecting it from rising oil prices and preventing further global warming and the resulting serious environmental disruptions caused by the use of fossil fuels. Therefore, in this study, We investigate at the reserves and the available capacity of other energy sources, such as solar, wind, biomass, wastes and small hydro energy. The results show that the available capacity of solar energy is 123,525 TOE/year, wind energy is 1, 871,748 TOE/year, and biomass energy is 30, 127 TOE/year. Waste energy has an available capacity of 6,629 TOE/year and small hydro energy is estimated at 2,617 TOE/year. The results of the available capacity of clean energy sources show that it is likely double the annual energy consumption of Jeju. Solar energy and wind energy are the greatest potential energy sources, compared to other energy sources. Furthermore, wind energy is available in the highest quantity.
Al₂O₃와 TiO₂를 플라즈마 용사한 코팅재의 마모 특성

This paper is to investigate the wear behaviors of two type ceramics, Al₂O₃ and TiO₂, by coated plasma thermal spray method under the lubricative environment. The lubricative environments are grease fluids, a general hydraulic fluids, and bearing fluids. The wear testing machine used a pin on disk type. Wear characteristics, which were friction force, friction coefficient and the specific wear rate, according to the lubricative environments were obtained at the four kinds of load and sliding velocity is 0.2 m/sec. After the wear experiments, the wear surfaces of the each test specimen were observed by a scanning electronic microscope.
