The relationship between Schwanniomyces occidentalis CBS 2863 (formerly castellii) and CBS 1153 (formerly alluvius), and their variety persoonii was examined at alpha-amylase gene level. Using Sch. occidentalis alpha-amylase gene as probe, Sch. occidentalis alpha-amylase gene homologues were obtained from Sch. occidentalis CBS 1153 and Sch. occidentalis var. persoonii. The restriction analysis of these homologues showed that the restriction enzyme sites between Sch. occidentalis CBS 2863 and CBS 1153 was identical but different between these strains and Sch. occidentalis var. persoonii.

The extracellular alpha-amylase was purified to homogenity from the culture filtrate of starch grown Sch. castellii CBS 2863. The purified enzyme was glycoprotein with a molecular weight of about 56 kDa. The pH and temperature optimum were 5.5 and 40C, respectively. The enzyme was fairly stable up to 40C and at acid pH range (pH 4.0-7.0). The apparent Km and Vmax of the enzyme toward starch was 1.0mg/ml and 100U/mg protein, respectively. The analysis of amino acid composition was found to be acidic protein. The amino acid sequence of N-terminal peptide consisted of Asp-Val-Ser-Ser-Ala-X-X-Thr-Arg-Ser-Glu-Ser-Ile-Tyr.

Schwanniomyces castellii의 제놈 DNA로 제조된 유전자 은행으로부터 cloning된 ${\alpha}$-amylase 유전자가 Sacchromyces cerevisiae에서 발현되었다. Cloning된 삽입 DNA 절편의 크기는 약 5.0 kb이었고, Southern 및 immunoblot 분석 결과 cloning된 ${\alpha}$-amylase 유전자가 Sch. Castellii로부터 유래되었음이 확인되었다. S. cerevisiae SHY3 형질전환체에서 Sch. Castellii ${\alpha}$-amylase 유전자발현은 모균주에 비해 낮았으나, 단백질의 분자량 및 효소의 성질은 Sch. Castellii에서 분리한 ${\alpha}$-amylase의 그것과 차이가 없었다. The gene encoding ${\alpha}$-amylase of Schwanniomyces castellii was cloned in Saccharomyces cerevisiae. The 5.0-kilobase insert was shown to direct the synthesis of ${\alpha}$-amylase. Southern blot analysis confirmed that this ${\alpha}$-amylase gene was derived from the genomic DNA of Sch. castellii. Immunoblot analysis showed that ${\alpha}$-amylase production from S. cerevisiae transformant was less than that of donor strain. The ${\alpha}$-amylase secreted from S. cerevisiae transformant was shown to be indistinguishable from that of Sch. castellii on the basis of molecular weight and enzyme properties.

본 연구는 광양만 퇴적물의 이화학적 조성과 중금속 함량을 알아보기 위해 함수율, COD, $H_{2}S$, 입도 및 10가지의 중금속을 17개 조사지점에 대해 분석${\cdot}$조사하였다. 조사기간동안 나타난 결과로서 퇴적물의 함수율 변화는 35.5${\sim}$53.8%를 나타내었다. COD와 $H_{2}S$는 각각 3.8${\sim}$12.9 mg/g, 0.1${\sim}$11.4 ${\mu}g/g$를 나타내었다. 퇴적물 입도의 구성은 입경 $74{\mu}m$ 이하가 40.5${\sim}$86.7% 74${\mu}m$ 이상이 11.5${\sim}$43.0%로 나타났다. 등농도 분포도를 이용한 중금속의 공간분포로부터 광양만 퇴적물에 영향을 미치는 몇 곳의 배출원을 추정할 수 있었다. 중금속 배출원 중 여천공단 내의 신풍천, 쌍봉천 그리고 하수처리장의 방류수역이 주요 배출원으로 판정되었다. 중금속의 분석 결과를 US, EPA 비오염해역의 guideline에 비교할 때 납과 수은은 guideline에 모두 적합한 것으로 평가되었으나 망간, 아연, 구리, 철, 비소, 크롬 등은 guideline을 모두 상회하고 있었다. For the purpose of surveying the physicochemical composition of sediment collected from Kwangyang Bay, the percentage of water loss, COD, $H_2S$, grain size and 10 heavy metals were studied at 17 sites. During the surveying period, the changes of the percentage of water loss were appeared $35.5\;{\sim}\;53.8%$. COD and $H_2S$ were showed $3.8\l{\sim}\;12.9\;mg/g$, and $0.1\;{\sim}11.4\;{\mu}g/g$, respectively, In composition of grain size on the sediment, percentages of grain sizes under $74\;{\mu}m$ were varied from 40.5% to 86.7% and above $74\;{\mu}m$ were varied from 11.5% to 43.0%. From the spatial distribution of heavy metal using contour map, we can suppose some heavy metal discharges which affect sediment of Kwangyang Bay, It was estimated that Shinpung creek, Ssang-bong creek, and draining area of sewange treatment plant were the main discharge among the heavy metal output sources. By comparison between present study and heavy metal guideline of nonpolluted sea sediment that is provided by EPA, US, it was showed that the contents of Pb and Hg were acceptable but contents of Mn, Zn, Cu, Fe, As, and Cr were higher than those of EPA guideline.

In Kwangyang bay, the biological and ecological surveys were carried out at seventeen sites both in surface and bottom water from July 1996 to May 1997. Fifteen abiotic and biotic parameters were determined on each sample. These data were subjected to simple regression, multiple stepwise regression and the principal factor analysis-to scrutinize the effect of environmental conditions on water quality and ecosystem. By the results of these analyses in Kwangyang bay, ecosystem were regulated by five factors for four seasons. The results showed that distribution of the microbial population was mainly influenced by inflow of fresh water, nitrogenous nutrients, suspended solids and water temperature. The overall size of microbial population was greater ten and five times than those obtained in 1982 and 1992, respectively.

The community compacts and mutual aid societies of Milyang Park family in the region of Cheongdo in the 19th and 20th Centuries had showed as follows: (1) The promotions of learning and educational activities of local aristocrats in Joseon dynasty based on the foundation of confucian norms represented how to take control of cultural hegemony in the local area. (2) The community compacts and mutual aid societies of Milyang Park family in the region of Cheongdo built social safety net. And they expended educational activities confined within the relatives, and thereby strengthened the social status of Milyang Park family in the regional community in the 19th through 20th centuries. (3) Janghyun Park inherited the tradition of his family, and thereby developed confucian tradition into national confucianism in modern Korea.

Flow is an optimal experience transforming mental state from boredom or anxiety to equilibrium. It is a melting pot of religious culture aiming at utopian values and mass culture searching for amused values, thereby integrating sacred value and profane fun. The core structure of flow experience is the cognitive optimization process approaching a balance of challenge and skill. Flow has three attributes: mental attention, raised feeling, unaffected behavior. On the foundation of flow experience, religious culture and mass culture share narratives composed by stage structure, images arousing sympathy, and ritualized behaviors practiced repeatedly. Through these, they tend to combine individuation with socialization. From the perspective of play pattern, variant modes of religious culture are divided into some typical groups. They are classified into traditionalism and liberalism according to whether it obey the rules or not. They are divided into anthropocentrism and theocentrism according to whether it emphasis on autonomous subjectivity of human will or not. Their combination are four: traditional anthrocentrism, traditional theocentrism, liberal anthrocentrism, liberal theocentrism. Therefore, religious culture aiming at utopian values has penetrated mass culture searching for amused values, the latter has exercised deep effects upon the former. From the perspective of religious culture, flow experience has four modes of cultural realization: apophatic/kataphatic mysticism, intentional pietism, practical activism, divergent enthusiasm.
