The compositions of lipid class and fatty acid of free lipids as non-starch lipid and bound lipids(extraction either at low or high temperature) as starch-lipid extracted from starch in mung bean(phaseolus radiatus L) was investigated. The contents of neutral lipids glycolipids and phospholipids in free lipids were 98.2% 1.7% and 0.1%, whereas those found in bound lipids were 84.3-85.7% 10.5-11.0%, and 5.2-3.3% respectively The major components of neutral lipid fraction in the bound lipids were triglyceride and esterified sterol and those were composed of 0% of total neutral lipids. Monogalactosyl idiglyceride and esteryl steryl glycoside were observed as main glycolipids components in both free and bound lipids. Among the phospholipids in the bound lipids phosphatidylinositol phosphatidyl serine and phosphati-dyl ethanolamine were identified an major constituents. The free lipids contained palmitic(50.2%) stearic(20.6%) oleic(8.5%) and behenic(7.4%) acids and bound lipids had more palmi-tic and linoleic acids but less stearic acid compared to thosed in the free lipids.

기후변화로 인한 수문학적 변동은 지속가능한 수자원 관리를 위해 중요한 인자로 고려되고 있다. 특히, 가뭄 등 기상재해는 자연재해 차원을 넘어서 사회적 갈등으로 발전할 여지가 크며 특히 수자원 배분은 환경, 경제를 뛰어넘은 생존의 문제로 발전하고 있다. 따라서 본 연구는 기후변화가 가져올 가뭄 등 재해관리를 위한 의사지원체계 구축하고 다양한 기후변화 시나리오에 대응할 수 있는 탄력성 있는 수자원전문가시스템의 개발을 통해 이상기후 및 가뭄대비 물분쟁에 대한 합리적 대안을 제시하고자 한다. 본 연구에서는 섬진댐의 상황을 모델로 하고 있다. 섬진강 유역은 섬진강댐의 건설당시 발 빠른 이주대책의 불이행으로 수몰지역 내에 초기 정착민들이 계속 거주하게 되어 댐 제원을 충분히 활용하지 못하고 있어 효과적인 치수사업에 어려움을 겪어오다가 공사간의 협력을 통해 치수능력증대사업을 추진하여 저수지의 저류량을 증가시키고자 섬진강댐 재개발 사업을 추진한 지역이다. 하지만, 유역내의 이상기후로 인한 수문학적인 변동과 가뭄으로 인한 물관련 당사자간의 용수확보분쟁의 소지가 있어 물관리를 위한 수자원전문가시스템의 개발이 시급한 실정인 지역이기도 하다. 대상지역 수자원전문가시스템의 개발을 목표로 HSPF(Hydrologic Simulation Program with FORTRAN)을 이용하여 기후변화로 인한 수문학적 변동성을 파악하였다. 그리고 수자원 전문가 모델로서 외국에서 사용되고 있는 SUPER, HEC-ResSim, RiverWare, MODSIM, WRAP, PowerSim, 그리고 STELLA의 장 단점 등 특성을 분석하여 국내에 적합한 수자원전문가시스템 갖추어야할 기능 및 구성을 분석하였다. 연구 결과 국내실정에 필요한 모델은 공영시각모형(Shared Vision Model)으로서 그 장점은 첫째, 수자원의 관리나 물분쟁시 반드시 필요한 유역의 물리적인 인자와 수역관리에 필요한 수문인자, 그리고 물분쟁의 소지가 있는 의문사항이나 문제점의 해결책을 위한 실마리를 제공할수 있다. 둘째, 물관련 이해당사자들이 직접 참여하여 모형을 평가하고 서로간의 이해관계를 위한 충돌이 발생했을 때 문제해결을 위한 대안을 제시할 수 있는 정보를 제공할 수 있다. 셋째, 물배분의 원칙에 따른 한쪽으로 편중된 대안이 제시되었을 경우에 공동으로 대안에 대한 평가를 통하여 평등한 물배분을 가능하게 한다. 넷째, 시민단체나 환경단체, 그리고 기관책임자들이 공동으로 모형의 형성과정을 지켜본 후 논의할 수 있어 이상적인 모형을 만들 수 있는 장점이 있다.

Recently, magnesium hydroxide ($Mg(OH)_2$) has many applications in various field, due to its outstanding characteristics such as a nontoxic, noncorrosive and thermal stable properties. In this study, different shapes of flower and flake type magnesium hydroxide were synthesized by precipitation method at room temperature using $MgSO_4$, $MgCl_2$ and $Mg(NO_3)_2$ as magnesium sources, NaOH and $NH_3$ as alkaline sources. Influence of synthesis on the morphological characteristics, sizes and shapes of magnesium hydroxide particles, was investigated, such as different precursors and parameters. The shape of magnesium hydroxide depend on magnesium and alkali sources. Average size of flower particle had about $1{\mu}m$, and flake had about 20 ~ 50 nm. The synthesised magnesium hydroxide groups were characterized by XRD, FE-SEM, FT-IR, EDS, PSA and TG.

This research evaluated factors on cement-based solidification process designed for hazardous sludge produced from electroplating industry. Four factors of sand/cement ratio, water/cement ratio, amount of wet sludge and amount of a precipitator, were investigated in terms of leachability and compressive strength of the solidified materials. Results of triplicate tests and statistical analysis indicated that sand/cement ratio(S/C) had the greatest effect on leaching of Cr(VI) from the solidified materials while water/cement ratio(W/C) on Zn and compressive strength. Cr(VI) was fixed better than Zn by portland cement. An experimental modeing was developed to estimate leached metal concentration and compressive strength at a given condition. Proper mixing criteria were also suggested for the use of the solidified mixture as construction materials. In solidification of 30g dry sludge, optimal condition was studied for S/C ratio, W/C ratio and the weight of precipitator which were 1, 1.5 and 1.075g respectively.

This article analysis the aesthetics of metal-body of (1989) and its metamorphosis of dehumanization through visual desires expressed by body images. This paper suggests theoretical analysis based on aesthetic views to understand the underlying meanings. The research categorizes three types of images; surreal image, grotesque image and eros image from the metamorphosis of dehumanization and transformation throughout the film. As the surreal image, the metamorphic process of transformation, demolition, derangement, illusion, and human desire continues to reflect the evil side of a human in everyday life. It also visualizes the images of exaggeration through weakness and bizarre side of metal-body. The grotesque image of body metamorphosis displays and symbolizes double-sides of bizarre and weak side of human in the everyday environment when malformation reaches its peak when Tetsuo finally shows his transforming figure. Finally, the eros image is analogized as a man's inner self and self-destruction in surreal world and a grotesque figure when overwhelming desire of transforming into rebirth of a perfect metal-body, Tetsuo. The surreal image, grotesque image, and eros image portraits human desires inner and outer-self into visualized image and that represents the means of excessive desire for dreaming of world domination with merging non-organic medium of metal and organic body to create a perfect body-image.

This study directly analyzes the wage distributions rather than indirectly looking at a few of their moments. It also investigates wage distributions using various descriptive and semi-parametric methods. The wage distributions of Korean manufacturing industries can in general be represented by three distinct forms, underdeveloped, advanced and the medium of the two. The discrepancies in these distribution forms are explained by differences in the labor-type distributions and their weights in the composition of wage distribution forms, and further clarified through various descriptive statistics based on them. However, the descriptive statistical analysis has a limit in that it shows mixed outcomes of different categoric variables. Then, this problem is resolved by applying a semi-parametric estimation of hazard function and the marginal effect evaluations of variable changes on estimated distributions not on the function. As a result of this marginal analysis, the common features and differences of categoric variables and their intensities of effects on distributions are revealed.

The spatial dose distribution was measured with ionization chamber as preliminary study to evaluate operator dose and to study dose reduction during neuro-interventional procedures. The zone of operators was divided into four area (45, 135, 225, and 315 degree).We supposed that operator exist on the four area and indicated location of critical organs(eyes, breast, gonad). The spatial doses were measured depending on distance( 80, 100, 120, and 140 cm) and location of critical organs. The spatial doses of area of 225 degree were 114.5 mR/h (eyes location), 143.1 mR/h (breast location) and 147 mR/h (gonad location) in 80 cm. When changed location of x-ray generator, spatial dose increased in $18.1{\pm}10.5%$, averagely. We certified spatial dose in the operator locations, Using the results of this study, It is feasible to protect operator from radiation in neuro-interventional procedures.

We augment an unrelated quantitative attribute to Bar-Lev et al.'s model (2004) which is composed of sensitive quantitative variable and scrambled one to present a multiplicative unrelated quantitative randomized response model(MUQ RRM). We also establish theoretical grounds to estimate the sensitive quantitative attribute according to circumstances irrespective of known or unknown unrelated quantitative attribute. Finally, we explore the relationship among the suggested model, Eichhorn-Hayre model, Bar-Lev et al.'s model and Gjestvang-Singh's model, and compare the efficiency of our model with Bar-Lev et al.'s model.

Commercial turkey poults not previously exposed to avian rotavirus were inoculated orally with the virus alone or in combination with E coki serotype 078 at 1, 7, 14 and 21 days of age. Turkey poults of 1, 7 and 14 days of age were susceptible to infection despite the presence of maternal antibodies against avian rotavirus in their serum. However, turkey poults at 21 days of age were less susceptible compared to those ages 1, 7 and 14 days. The clinical signs in poults of all ages were mild. Viral antigens were demonstrated in the mature villous epithelial cells of the duodenum, jejunum and ilem. Histopathological lesions were characterized by vacuolation of the epithelial cells and heterophil infiltration in infected turkey poults. A significant difference in D-xylose absorption was observed between control and rotavirus infected groups at 1 and 3 days post-infection in 14 days old turkey poults.
