Fast pyrolysis of Quercus acutissima was carried out in a fluidized bed pyrolyser and then the physicochemical properities of obtained bio-oil were analyzed using GC/MS. The yields of bio-oil of Quercus acutissima and Larix leptolepis from a fluidized bed pyrolyzer were maximized at $350^{\circ}C\;and\;400^{\circ}C$, respectively. This is due to the difference or cellulose content between the two tree species. Above the optimum temperature, the yields of char and oil decreased as the reaction temperature increased, but the yield of gas-phase and water fraction increased. It is concluded that this phenomenon is occured by secondary pyrolysis in the free board. The feeding rate of the sample in a fluidized bed pyrolyser did not affect the yields and composition of products, because of a sufficient mixing between bed materials and sand. 유동층 열분해로에서 상수리나무의 급속열분해를 수행하고 생성된 바이오오일의 물리화학적 특성을 GC/MS를 이용하여 분석하였다. 유동층 열분해로에서 얻어진 상수리나무와 낙엽송의 바이오오일 수율은 각각 $350^{\circ}C,\;400^{\circ}C$에서 최대치를 보였으며 이는 두 수종간의 셀룰로오스 함량차이에 기인하는 것으로 추정된다. 최적온도 이상에서는 반응온도가 증가할수록 프리보드에서의 2차 열분해에 의하여 촤와 오일의 수율이 감소하였고 가스상 성분과 수분의 함량이 증가하였다. 유등층 열분해로에서 시료의 투입량은 생성물의 수율과 조성에는 큰 영향을 주지 않았으며 이는 충분한 혼합이 이루어지기 때문으로 판단되었다.

The withdrawal method for protecting the uncontaminated part from the spread of contaminants was suggested by a simultaneous equation. The formulation of them is based upon the build up of the ridge part between the contaminated and uncontaminated parts that resulted from the efficient use of barrier wells. The quality in the withdrawn groundwater depends upon the heads at wells no. 5 and 6. The determination of pumping rates and qualities with changing the heads at wells no. 5 and 6 should be given by considering the demand for water use and the capacity and cost for removing the contained contaminants. The results of this study should be used in taking a plan for supplying water use as well as preventing the spread of contaminants from some known contaminated sources.

MRE(Magneto-rheological Elastomer) is a material which shows reversible and various modulus in magnetic field. Comparing to conventional rubber vibration isolator, MREs are able to absorb broader frequency range of vibration. These characteristic phenomena result from the orientation of magnetic particle (i.e., chain-like formation) in rubber matrix. In this study, Silicon was used as a matrix in order to manufacture MREs. Magnetic reactive powder(MRP), having rapid magnetic reaction, was selected as a magnetic particle to give magnetic field reactive modulus. The mechanical properties of manufactured MREs were measured with the application of magnetic field. The analysis of MR effect was carried out by FFT analyzer with various induced magnetic field. As the addition of CIP and induced magnetic field intensity increased, increment of MR effect was observed.
