강남콩의 지방질을 chloroform-methanol-water (1:2:0.8, v/v)의 용매로 추출하고 이를 silicic acid column chromatography에 의하여 중성지방질, 당지방질 및 인지방질로 분획한 다음 이들의 지방질 조성과 지방산 조성을 TLC, GLC에 의하여 분리 정량하였다. 강남콩의 총지방질 함량은 1.9%이었으며 이중 중성지방질은 48.2%. 당지방질은 7.5%, 인지방질은 44.3%이었다. triglyceride는 중성지방질중 64.6% 함유된 주성분이었으며 가장 함량이 높은 인지방질과 당지방질로서 phosphatidyl choline은 인지방질중 32.9%, esterified steryl glycoside는 당지방질중 38.8% 함유되어 있었다. 강남콩의 주요 지방산은 linolenic, linoleic, oleic, palmitic acid이었으며 특히 linolenic acid는 그 함량이 높아 총지방질의 경우 37.1%, 중성지방질의 경우 50.4% 함유되어 있었다. Lipids of kidney bean were extracted by the mixture of chloroform-methanol-water (1:2:0.8 v/v), fractionated into neutral lipids, glycolipids and phospholipids by silicic acid column chromatography, and the composition of these lipid classes were determined by TLC and GLC. The lipid content of kidney bean was 1.9%, and the lipid was consisted of 48.3% neutral lipids. 7.5% glycolipids and 44.2% phospholipids. Triglyceride was the major component of neutral lipids (64.6%). The major glycolipid and phosphlolipid were esterified steryl glycoside (38.3%) and phosphatidyl choline (32.9%). The major fatty acids of kidney bean lipid were linolenic, linoleic, palmitic and oleic acid. Linolenic acid contents were very high to be 37.1% in total lipid and 50.5% in neutral lipid.

Recently, wind energy has been in the spotlight as a alternative energy resources in Korea. To improve it's efficiency, It is essential that large scale Wind Turbine Generator System should develop and floating offshore structure is suitable for this. In this environment, big, strong and heavy Tower is very important part to support the Wind Turbine System. In this paper, structural analysis is established on Tower by considering load factor of blade and floating barge through finite element tool.

In this paper, We propose the wave energy converter system of floating cylindrical structure. The new shape structure system is a movable-body-type wave energy converter. The wave energy converter system of the cylinder lying on the water is designed as to be unstable condition. That is, the meta center height of this system is below 0. The structure's motion is to be rotational. The equation of motion is established on the structure's motion for the wave. And this equation of motion is solved and structure's motion is analysed by Runge-Kutta-Nystrom method(RKN method). Within the limit that the wave is not disturbed by the object, the response of rotation tend to be proportional to the diameter of cylinder. Because meta center height is 0, It can be rotated unidirectionally by reciprocating motion of the waves.
