This study was made to expand the knowledge of the relationships between the mussels and the bitterlings (Acheilognathus yamatsutae Mori) and the materials were collected in lake Uiam from Mar. 1987 to Oct. 1988. The female fish has developed a prominent ovipositor and the male sidplayed a nuptial color during reprodductive period from the late April to August. The territory-defending behavior was four types and the extent of territory was about 60cm in diameter and 30cm in height. The mussel was the most important factor to stimulated the reproductive behavior rather than male and female. The number of total mean egfs in a fish was 300 and the mean egg size was 1.97mm in length and 1.74mm in breadth of ovoid shape. The preference of the oviposition of fish to the messels was order of Unio douglasiae, Lamprotula gottschei, Anodonta fukudai and A. woodiana. The egg began to hatch approximately 33 hours after insemination and reached the free swimming stage within 22 days after insemination at water temperature 25±1℃. The sex ratio of the male to the female was 1:1.73 and approached to an adult-shaped fish from about 40mm of body length. The contents of stomach were the algae and zooplanktons.

This study was carried out to determine the attachment parts and rates on the host fish and the successive stages of the glochidial encystment. A scanning electron microscope observation of the glochidia, the larvae of freshwater brivalve, Anodonta arcaeformis flavotincta, on the host fish, Carassius auratus, was conducted. The attachment rates on the host fish were 30.1%, 22.3% on the pectoral, the caudal, and the pelvic and anal fin, respectively. Glochidia, once attached to the host, have become encysted within 27 hours. The glochidia in fish tissues have sloughed between 13 days and 15 days when the water temperature was 16℃ in laboratory. During encystment, the epithelial cells of the host fish migrated actively toward the attached glochidia and covered them. In the encystment process, the encysted tissues in the host have become loose in seven days and exposured a pat of the glochidium in eight days after infection. No changes of the glochidial size have found before attachment and after sloughing.

The purpose of this study is to estimate the National Health Insurance budget needed for the Korean elderly's denture service coverage. For more exact estimating the budget, denture need and demand were calculated by using 2000 National Oral Health Survey data. The results were summarized as follows ; 1. Over 65 years old, full denture and partial denture need per arch were each 8.5% and 16.8%. And over 70 years old, those were each 11.3% and 17.8%. 2. Over 65 years old, full denture and partial denture demand per arch were each 22.8% and 21.2%. And over 70 years old, those were each 27.%% and 21.1%. 3. Based on the denture need, the health insurance budget needed in the first operative year was about 955.4 billion won, over 65 years old and about 644.2 billion won, over 70 years old. 4. Based on the denture demand(wear), the health insurance budget needed in the first operative year was about 207.5 billion won, over 65 years old and was about 151.6 billion won, over 70 years old. If health insurance policy of elderly's denture service coverage is performed, actual denture wear rate is going to increase, and the budget needed is also increasing. Because current National Health Insurance budget status is poor, it is difficult to execute health insurance coverage for elderly's denture service. Therefore we suggest that health insurance coverage for preventive service is to be considered in order to reducing denture need in the long term view.

Flocculant-producing microorganisms were screened from obtained strains in the laboratory using a pulp-wastewater treatment as the flocculating agent. K-111 strain that had high flocculating activity among them was selected and identified as Bacillus sp. K-111 16s rDNA sequencing. The favorable medium for the production of flocculant was glucose 1.5%, NH_4NO_3 0.2%, tryptone 0.01%, K_2HPO_4 0.08%, KH_2PO_4 0.06%, CaCO_3 0.03%, MgSO_4·7H_2O 0.005%, MnSO_4 0.005% in 1 liter of D.W. at initial pH 7.0. The optimum culture temperature and pH were 30℃ and pH 7.0, respectively. the flocculating activity was observed most highly after 36 to 48 hr of cultivation at the optimum conditions. the flocculating activity of produced biopolymer on optimum conditions was about 2.5-fold higher than that of screening medium.

The spawning condition was investigated of the bitterling, Acheilognathus yamatsutoe Mori in aquariums. Sexual responses in male and female bitterlings were very sensitive to the mussel rather than the other sex. But spawning behavior was shown ouly when all of the male, the female and the mussel were present. And the sexual response was not shown at all when there was no direct contact with the live mussel.

Organizational structure significantly influences form performance. A recent survey of logistics professionals revealed that centralized structures accommodated logistics system integration better than decentralized structures. Also, centralized forms spent a lower percentage of net sales on logistics costs and information systems supports costs than decentralized forms. On the other hand, no significant differences were identified between centralized and decentralized forms in terms of information system performance. Information system support needs were addressed comparably regardless of organizational structuring. However, while centralized and decentralized firms exhibited similar capabilities in terms of effectiveness, centralized forms appeared to be more efficient.

The purpose of this study is to substitute water-based painting materials for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters. This study assessed the exposure of organic solvents to the painters using water-based and solvent-based painting materials and compared compositions, painting processes and the health hazards of the application of these alternative painting materials. The results of this study are as follows. 1. solvent-based painting materials used in motor-repairing process consist of various organic solvents, which consist primarily of toluene, xylene, ethyl benzene, ethyl methyl bezene, trimethyl bezene, ethyl acetate, butyl acetate, methyl isobutyl ketone, 2-ethoxy ethanol, 2-ethoxy ethyl acetate and toluene-2.4-diisocianate and the others. These organic solvents are know as health-hazardous substances. But water-based painting materials are high-solid, low-solvent ones and consist of such two organic solvents as 2-butoxy ethanol and 2-heptanone and the others. 2. The painters using solvent-based painting materials in motor-repairing process are exposed to various organic acetate, methyl isobutyl ketone, trimethyl benzene, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. But the painters using solvent-based ones are only exposed to 2-butoxy ethanol and 2-heptanone. 3. By using water-based painting materials in stead of solvent-based painting materials containing health-hazardous organic solvents, the exposure of such organic solvents in the painter's breathing zone can be largely prevented. 4. This study recommends water-based painting materials as substitutes for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters.

신사회운동과 政治 : 政治勢力化의 요인과 쟁점 Factors and Issues for Politicking

권태환,송호근 서울대학교 사회과학연구원 2000 한국사회과학 Vol.22 No.1

이 연구의 결론에 해당하는 이 논문은 사회운동의 정치세력화의 다양한 양상을 비교론적 관점에서 권역별로 분석한 앞의 논문들의 연구결과를 종합하여 정치세력화의 개입하는 구조적 요인들을 체계화하는 데에 목적을 둔다.앞의 연구들은 '정치세력화'를 신사회 운동의 정당정치화에 국한하기보다는 어떤 결집된 형태가 아니더라도 정부와 정치권의 중대한 정책결정에 무시할 수 없는 압력을 가할 수 있는 운동형태로 규정하여 상당히 폭 넓은 입장을 취한다.'정치세력화를 향한 길'을 일차적 과정과 이차적 과정으로 구분하고, 이차적 과정을 정치세력화의 중대한 계기로 보았다.이 논문은 이차적 과정을 관할하는 가장 중요한 요인으로 '정치적' 기회구조를 지목하고, 정치적 기회구조를 지배집단의 구조와 이념적 관용의 수준, 국가의 구조, 정당구조로 세분하여 각각의 구체적 양상을 검토하였다.이러한 관점에서 본다면, 한국의 사회운동은 다른 국가들에 비하여 정치세력화의 조건이 비교적 양호하고 조직적 기반도 그런대로 괜찮은 편이다.그러나, 여전히 낙관적인 전망을 허용하는 것은 아니다. As a conclusion of this research, this paper aims at summarizing and systemizing the result of these papers published in this volume that are a comparative analysis of various aspects of politicking of civil social movements (CSMs) in East Asia, Latin America, and South Korea. This research stands upon a broad concept of the politicking of CSMs that includes dispersed claims of civilians without a visible organization that can affect governmental and political decision making. This paper divides the road to power into two consecutive stages, i.e., the first and second stages. The second stage is more decisive on the politicking than the first stage. The success and failure of the second stage relies upon the 'political opportunity structure' that consists of three important factors: the degree of ideological toleration and the structure of the ruling class, the structure of state and political party. From this standpoint, Korea's CSMS are comparatively in favorable conditions for politicking than Latin America and East Asia. But it does not still allow optimistic prediction.

홍천강 상류에 서식하는 묵납자루, Acheilognathus signifer의 성 성숙과 산란시기

백현민,송호복,권오길 한국어류학회 2003 韓國魚類學會誌 Vol.15 No.4

묵납자루, Acheilognathus signifer의 성적성숙과 산란시기를 연구하기 위하여 2002년 3월부터 동년 10월까지 북한강 수계의 홍천강 상류인 내촌천에서 조사, 연구하였다. 생식소성숙도지수(GSI)는 4월에 암컷(GSK = 6.95±0.83)과 수컷(GSI = 2.84±0.55) 모두 최대치로 나타났고, 암컷은 8월(GSI = 2.02±0.91), 수컷은 9월에(GSI = 0.54±0.50)최저치를 보였으며, 10월부터 GSI가 상승하였다. 산란관길이 지수(OI)는 5월에 최대로 신장(26.53±8.34%)되었으며, 8월에 가장 축소(5.77±1.37%)되었다. 암컷은 체장 45㎜ 이상, 수컷은 체장 40㎜이상부터 생식 활동이 가능 할 것으로 추정되었다. 암컷과 수컷에서 산란에 참여 비율이 높은 연령군은 2년생이었으며, 수컷은 암컷보다 3년생의 참여 비율이 높았다. 생식 주기는 3~4월의 성숙기 5~6월의 완숙 및 산란기, 7~8월의 퇴화 및 휴지기, 9~10월의 성장기로 구분되었다. 포란수는 141~314(평균 225)개였으며, 성비에서 암컷이 수컷보다 우세하게 나타나 암수의 성비가 1:1이 아니었고, 암수의 성비는 유의한 차이를 보였다(c^(2) = 13.5, P<0.05). 본 종의 산란 성기는 GSI가 높은 값을 나타내고, 산란관이 최대로 신장되며, 난소와 정소가 최대로 성숙하는 5월로 추정되었다. The Korean bitterling, Acheilognathus signifer, collected in the Naechoncheon, Hongchungun, Kangwon-do, Korea, from March to October 2002, were examined for sexual maturation and spawning season. Gonadosomatic index (GSI) and ovipositor indices (OI) values reached the maximum in May. The body length at sexual maturity was estimated at 45 ㎜ for the females and 40 ㎜ for the males. Reproductive cycle can be classified into the growing stage (September to October), mature stage (March to April), ripe and spent stage (May to June), and degenerative and resting stage (July to August), Two-year-old populations were the highest participants in spawning. Fecundity of A. signifer ranged from about 141-314 (average 225) eggs. The sex ratio of fema1e : male was not significantly different from 1 : 1 (χ² = 13.5, P< 0.05).
