  • High performance liquid chromatographic (HPLC) analysis of mycelia of Sclerotium rolfsii grown in broth medium supplemented with garlic (Allium sativum) and onion (Allium cepa) was carried out to estimate qualitative and quantitative changes in phenolic acids. Several phenolic acids, such as gallic, chlorogenic; ferulic, o-coumaric and cinnamic acids were detected in varied amounts in mycelia grown on such media as compared to control. Phenolic acids represents a wide range of secondary metabolite found in the cells of plants and microbes including fungi. The growth characters of S. rolfsii in various supplements also varied from thin and transparent to thick and opaque.

  • Three marine species of Cladophora (Cladophoraceae, Chlorophyta) commonly occurred on the coast of Cheju Island, Cladophora conchopheria Sakai, C. gracilis (Griff.) Kutzing and C. wrightiana Harvey were described morphologically, considering their taxonomic characters. C. conchopheria Sakai, specifically growing on the surface of Lunella coronata, is a very minute plant of 550-990 ${\mu}{\textrm}{m}$ in height and has intracuticular adventitious rhizoids borne from the lower portion of the first to fourth segments. C. gracilis occurs on calm habitat and shows a pseudosympodial growth with pectinate branchlets. c. wrightiana always produces protoplasmic protuberances at the node of middle portion of thallus. It grows to 30 cm or more in height and is dark green in subtidal bottom.

  • This study aims to inquire into the expressive characters of Shiro Kuramata's works regarding his design languages. His design languages, based on sentimentality and aesthetics characteristic of the orient and his unique memories and experiences, can be defined as nongravitation, fioatation and transparency. And the definition can be completed by his unique extinguishing technique, eliminating the structure with materials without feature, such as glass and acrylic and expanded metal, steel mash and 'Star piece Terrazzo' a material which he has invented. This study examines Shiro Kuramata's design works from the late 1960's to 1991, the year of his death, the background of his growth and the art and people who have influenced him. It also looks into the indigenous cultural background and his unique memories and experiences. The study also considers his furniture works and interior design to read his languages properties of the materials and expressive techniques. The study presents data on Shiro Kuramata and puts forwards the significance of his works and tries to lead the way of the interior design by application techniques of materials.

  • The morphometric truss characteristics and classical dimensions of the marine medaka, Oryzias dancena, that might distinguish diploid and triploid fish were examined. Significant differences in all the classical and truss dimensions of the diploid and triploid fish were observed in both sexes (p<0.01). All the dimensions of the triploid fish were greater than those of the diploid fish. The triploid marine medaka shows sexual dimorphism in these characters, and the sexual dimorphism of the triploid marine medaka is similar to that of the diploid marine medaka. Thus, when their classical dimension and truss dimension was measured, the growth of triploid marine medaka is faster than that of the diploid fish, and it displays clear sexual dimorphism, with male fish having longer dorsal and anal fins than female fish.

  • Pregnant Wister rats were given daily subcutaneous administrations of methamphetamine (MAPT; varying doses ranging from 1.0 to 4.5mg/kg) from days 7 to20 of gestation and teratogenic effects have been determined. The teratogenic effects inducible with orally administered caffeine (90mg/kg/day)for the same durations were used as the positive controls. MAPT doses greater than 2.0 mg/kg have suppressed the rate of maternal weight gain. Some of the offsprings (F1) of the prenatal MAPT treated groups had decreased growth rate and delayed development of physical characters and functional reflexes. The male offsprings of the MAPT treated groups had significant decreases in their spontaneous motor activity but had enhanced conditioned avoidance responses. However, the mating performances of these offsprings were not affected. These results indicated that prenatal exposure of MAPT may induce some behavioral teratogenicity in rats.

  • The purpose of this study is to understand the subjective experiences of married women about marital adjustment. Eleven women were interviewed, creating interview texts that were analyzed by van Manen's wholistic and selective approaches. These women explained marital adjustment in five aspects: being realistic, accepting their identity as married women, taking the middle, acting craftily, and building up their characters. In conclusion, these women experienced the growth and transition while they adjusted to their marital life in the early stage of marriage.

  • A genetic analysis of reproductive characters of masu salmon at three year classes was described. the reproductive performance of masu salmon spawning at 2 years of age was analyzed using data number fertility hatchability and growth traits to the juvenile stage. The phenotypic correlations among the traits were also estimated. it was determined that egg volume was the principle deter-minant of egg number and that the relationship of number to size was negative. It is recommended that selection for egg size be included in all selection programs and egg number be ignored in any welection program designed to increase body size. Phenotypic correlations between body size of parents and egg traits as well as between body size of offspring and egg traits were not significantly positive or negative magnitude at three year classes.

  • A strain of Streptomyces sp. isolated from soil was found to produce extra-cellular $\beta$-lactamase associated partially to the cell growth. The $\beta$-lactamase was purified from the culture supernatant through anmonium sulfate fractionation, ion-exchange chromatographies and gel filtration. The final purification fold and recovery yield were 57 and 6.2%, respectively. Molecular weight of the $\beta$-lactamase was estimated to be about 67, 000 by SDS-polyacrylamide gel electrophoresis. The optimal reaction condition was at pH 7-8 and at 35-$45^{\circ}C$. The $K_m$ and $V_{max}$ values of the enzyme for penicillin G were estimated to he 3 mM and $3\times 10^3$ $\mu\textrm{M}$/min/mg protein, respectively. The purified $\beta$-lactamase was classified to the class A enzyme hydrolyzing only penicillin.
