A halophilic bacterium was isolated from domestic marine. The bacterium was gram negative and motile. Transmission electron micrograph after cultivating for 6-, 20-, 72-, and 144 hrs showed that it was bacilli and contained intracellular granules, which were pleomorphic, larger in density by the time and considered to be PHB since they were positive on the sudan black B staining. The presence of sodium chloride was critical, because the isolated marine bacterium could not multiply and even produce any immunostimulant in the deficiency of sodium chloride. The strain produced an immunostimulant, which was investigated for the biological characteristics. The optimal conditions for the production of the immunostimulant were 1 % dextrose and 1 % yeast extract in artificial sea water for carbon and nitrogen sources, respectively. The initial pH and growth temperature for the production were 8.0 and $30^{\circ}C$ under the presence of oxigen, respectively.

The optimal medium composition for the production of carotenoid pigment from Haloarcular sp. EH 1 as a dietary for fishes were 1.0% sucrose, 1.0% yeast extract, 25% sodium chloride, 0.3% sodium citrate, 0.2% potassium chloride, 2.0% magnesium sulphate, 0.002% ferric sulphate(pH 7.0). The incubation temperate, aeration rate and agitation speed were 40oC, 100ml medium/500ml vol. shaking flask, and 180 rpm/min. The carotenoid pigment production was highest after 5 days of incubation with the light.

Opuntia ficus-indica var. sabotan was administered with diet for 5 weeks on db/db diabetic mice and its antidiabetic activity was investigated. Leaves of Opuntia ficus-indica var. sabotan inhibited the increase of body weight, glucose elevation in blood and urine, and protein excretion in urine, and protein excretion in urine. Opuntia ficus-indica var. sabotan also inhibited the intestinal maltase and sucrase activity on db/db Mice loaded with maltose and sucrose. However, it did not significantly lower HbAlc in blood of db/db mice. These results suggest that leaves of Opuntia ficus-indica var. sabotan could be effective on insulin-independent diabetic mellitus type 2.

The extremely halophilic archaebacterium Haloarcular sp. EH-1 was isolated from solar salts. Haloarcular sp. EH-1 accumulated poly(3-hydroxyalkanoate) (PHA) as intracellular granules. PHA production in batch culture have been studied. The PHA was identified as poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHB/HV) of 3-hydroxybutyric acid and 3-hydroxyvaleric acid by the analysis of GC, IR and NMR. The melting temperature of PHB/HV was 152.46$^{\circ}C$, viscosity was 1.25 ㎗/g, and molecular weight was $1.44 X 10^5.$

The objective of this study was to develop bioactive ginseng yogurt, fermented by B. minimum KK-1 and B. cholerium KK-2, which showed transforming activity of ginseng extract to compound K. Among older people, 3% ginseng yogurt fermented by B. minimum KK-1 and mixed with Bifidobacterium KK-1, KK-2 showed the highest overall acceptability(6.80, 6.80) among 1%(3.87, 3.67), 2%(4.40, 4.53) and 3% ginseng yogurt. The pH of ginseng yogurt was lower than that of plain yogurt. During 9 days of storage, the pH of each yogurt slightly decreased and then increased until 15 days of storage. The 3 8.25 log CFU/g and B. cholerium KK-2; 7.78 log CFU/g). Therefore, ginseng might be used as a growth factor during the fermentation of yogurt. The L value of ginseng yogurt decreased, and the a and b values increased, with increasing ginseng concentration.

The protective effect of Bifidobacterium breve K-110, K-111 and B. infantis K-525 on carbon tetrachloride induced hepatotoxicity in rats was investigated. Among them, B. infantis K-525 had the most potent hepatoprotective activity. It reduced serum aspartate aminotransferase and alanine aminotransferase levels to 51% and 80% of the $CCl_{4}-treated$ groups, respectively. In rat liver homogenate intoxificated with $CCl_{4}$, B. infantis K-525 inhibited in vitro as well as in vivo lipid peroxidation more than the other Bifidobacteria.

본 논문에서는 유전 알고리즘을 이용한 강의시간표 작성 시스템 설계 방법을 제안한다. 강의시간표는 교과목의 강의시간, 강의실, 교수자 등의 정보를 시간표 테이블에 할당하는 문제이면서 스케줄링 문제이다. 강의시간표로써의 의미를 가지기 위해서는 강의실 중복 회피, 교수의 강의시간 중복회피와 같은 필수 제약조건(Hard Constraint)을 만족해야 한다. 또한, 강의시간표 문제는 NP-Complete 문제로 알려져 있으며 기존의 Exact 알고리즘으로는 최적 해를 구하는 것이 힘들다. 따라서 본 논문에서는 휴리스틱 알고리즘 중의 하나인 유전 알고리즘을 교과목의 강의시간 배정 부분과 강의실 배정 부분을 각각 별도의 부시스템 (Sub-system)으로 나누어 적용하는 방법을 제안한다. 실험 결과 강의시간표로써의 의미를 가질 수 있는 필수 제약 조건을 만족시킬 수 있음을 알 수 있었다.

The Purpose of this study was to find in the art the basis of originality appeared on the fashion design and investigating the erotic expression appeared on the ornaments how art surrealism, pop art, post moderninism-formularize in the modern fashion. This study about the expression of eroticism and modren costume, through the source of pictures contained in art books and mode magazine and documents investingation has resulted as follows: First, the formality and contents that related art and fashion shows us a various aspect. That based on modeled characteristic and various technique of the art. Second, the expression of eroticism in fashion expressed differently in style, material and expression method that is more strongly, sometimes metaphorically with spirit of the time's. Third, the expression of eroticism in fashion whether direct way or symbolic way has appeared as partial exposure of the body. It is appearing to the course that can display individuality of each person over the taboo of the part and the previous limitation of fashion.

Acute oral toxicity of Bifidobacterium breve K-110, Bifidobacterium breve K-111, Bifidobacterium infantis K-525 were studied in Sprague-Dawley rats of both sexes. In this study, we examined number of deaths, clinical signs, bod weight and gross findings for 14 day after single oral administration of B. breve K-110,B. breve K-111 or B. infantis K-525 with different levels. They did not show any toxic effect in rats and oral LD$_{50}$ value was over 5 g/kg in rats.s.
