Zooplankton samples were collected at ten stations in lower part of Han river during the period between June and September 2011. A total of 23 taxa occurred, which consisted of six species of cladocerans, four taxa of copepods, 11 species of rotifers, one species of nematod and a aquatic insect, respectively. Abundance was fluctuated between 1,700∼14,530 individuals/m3. Maximum abundance was recorded at Janghang wet land in June and drastically decreased in July possibly due to heavy rain fall in the summer. Higher abundances were observed at upper stations again in September. Dominant species were Bosmina longirostris, copepodites and Brachionus calyciflorus. Only an occurrence of carnivorous cladoceran of Lepodora kindtii at Janghang wet land seemed to indicate the well conservation of the wet land in lower Han river.

This study was designed to investigate the effect of styrene-7,8oxide(styrene oxide) on their potentialto induce of sister chromatid exchanges(SCE) in phytohaemagglutinin-stimulated human whole blood lymphocytes cultured for 72 hours. The treatment with styrene or styrene oxide diluted by acetone were carried out 48 hour before harvest. The concentration of styrene was 1.0,1.5 and 2.0 mM and that styrene oxide was 50 and 100 M, and control group was treated wiht acetone only. A dose-dependent increase of SCE was observed in lymphocytes treated with styrene or with styrene oxide. The toxictiy of styrene oxide was about 15times of that of styrene considering the ability of inducing SCE in the cultured human lymphocytes and cell replicationindex. This study result was on the line that the active metabolite formed from styrene through the action of the erythrocytes is styrene oxide.

Studies on the seasonal distribution of zooplankton were carried out in 1994 in waters off Yongkwang Atomic Power Plant. Zooplankton samples were collected four times seasonally at six selected stations. Forty - three taxa of zooplankton were distributed and 25 species representing 21 copepods, 2 chaetognaths, 1 protozoan and appendicularian were identified to species level. Zooplankton abundance varied between 840-42, 014 indiv. m-3 and were recorded the highest abundance in September and the lowest in February. Seasonal succession in the dominant species was observed from winter and spring with Acartia omorii to summer and autumn with A. pacifica and Paracalanus indicus. With the prevalence of ueritic copepods all the year round, i.e., A. omorii, A. pacifica and P. indicus, the studied waters were revealed to have the typical zooplankton fauna in coastal waters of the Yellow Sea.

Six times of field study on seasonal distribution of zooplankton community during the period from June 1995 to June 1996 in lower Han-river revealed that a total of 69 taxa of zooplankton distributed in the study water. Rorifers showed prosperity in species number with the followence of cladoceran and copepods. zooplankton dynamics in the study water maintained high secondary production in the spring. Extremely low abundance was observed with a few number of species in the winter. The occurrence of some rotifers of Brachionus caluciflorus and Asplanha priodonta indicates the study water being as eutrophic condition. No indicator species of cladocerans and copepods, however, occurred.

Alkyd resin의 분산제로서의 응용성을 알아보기 위하여 여러 가지 분자량의 PEG와 phthalic anhydride로부터 합성된 diacid와 stearic acid와 1,1,1-trimethylolethane으로부터 합성된 diol과의 축합중합에의하여 여러 가지조성의 alkyd resin을 합성하였으며 이들을 trichloroethane(TCE)용매 중에서 분산시 투광도, 시간별 침강속도 및 합성한 alkyd resin의 HLB값 등을 측정하였다. 실험결과 본 alkyd resin은 수지중에 친수성 부분과 소수성 부분을 가지고 있어 비교적 극성인 미립자들이 비극성 용매중에서 고르게 분산되었으며 PEG 1,000을 사용하여 합성한 alkyd resin(HLB값은 10.19)와 TCE용매 중에서 미립자들의 분산성이 가장 우수하였다. 또한 PEG분자량 증가와 함께 친수성 부분이 증가되어 분산성이 떨어짐을 알 수 있었다. Alkyd resins were prepared from phthalic anhydride, polyethylene glycol, stearic acid and 1,1,1-trimethylolethane. These product have both hydrophilic and lipophilic part. Dispersion tests were carried out spectrophotometrically in 1,1,1-trichloroethane using particles. Particles dispersion with alkyd resin showed that it was maximum when molecular weights of hydrophilic and lipophilic part were close to one. This happened when alkyd resin was prepared from PEG 1,000. This result was turned out to agree well with HLB value 10∼11.

Impacts of the power plant operation located in the coastal area of Samchonpo were investgated in the view point of the population dynamics of zoo -and phytoplankton five times seasonally during the period from August 7 1990 to August 27 1991. Ninty nine taxa of phytoplankton, representing 2 forma, 1 variety, 79 species and 17 unidentified species belonging to 39 genera were tentatively identified. Phytoplankton standing crops varied with months and stations ranging from 5.8×104cells /l (November 1990, station 5) to 4.83×106cells /l (May 1991, station 4) in surface, ranging from 2.9×105cells /l (Novemver 1990, station 5) to 5.90×106cells /l (May 1991, station 4) in bottom. Dominant species through the present study were Chaetoceros compressus and C. curvisetus in August 1990, Nitzschia pungens in November, Eucampia zodiacus and Skeletonema costatum in February 1991, Leptocylindrus danicus in May, and S. costatum and S. tropicum in August. Causative organisms of red -tide due to diatoms were 24 taxa. Among them, six species occurred throughout the year ; Chaetoceros debilis, Cylindrotheca closterium, Guinardia flaccida, Nitzschia pungens, Rhizosolenia setigera and Skeletonema costatum. Chlorophyll -α was fluctuated ranging from 6.18mg /m3 (August 1990, station 1) to 23. 77mg /m3(February 1991, station 4) in surface, This value of chlorophyll -a might be assumed that eutrophication occurred in studied waters. Twenty two taxa of zooplankton communities, representing 14 copepods, 4 cladocerans, 2 chaetognaths, 1 protozoan and 1 appendicularian were identified. Zooplankton abundance varied with months and stations ranging from 1,677 indiv./m3 to 18,057 indiv./m3.

The traditional culture has been developed for a long time with an unique property according to folk character, custom and environment within an area. Especially in 1906, when the westerners were interested in oriental cultures more and more, Paul Poiret presented Japanese traditional dress of napping sleeve coats and harem pants, henceforth japanese fashion theme began to rise. The Japanese style rose as an important fashion item of the modern fashion, with various fashion themes such as orientalism, ethnic, folklore, ecology, etc., needless to say of activities of Japanese designers. The revealed patterns on Japanese dress and it's ornament plays a role of expressive decoration as well as stand for the nation, the ideology of the age and aesthetic consciousness. For this reason, it is necessary to study Japanese traditional patterns expressed in modern fashion systematically. Therefore, in this research, the demonstrated Japanese traditional patterns on the modern fashion were divided into natural, artificial and complex design and were looked out the characteristic, furthermore it was studied in regard that Japanese patterns were how to apply in modern fashion. It was concluded that the characteristics of the Japanese traditional patterns presented in the modern fashion were as follows: first, creation of environmental friendly design using plenty of natural materials; second, expression of paint-like impression and beauty of margins by simplifying of patterns; third, expression of amusing design by using bright colors and print; finally, various patterns were spreaded out complicated on dress. The characteristics of Japanese traditional patterns in the above were expressed in the modern fashion.

Impacts of thermal discharges on zooplankton dynamics were studied during the period between March and October, 1993 at five selected stations in waters adjacent to Seosan Power Plant. Nineteen taxa of zooplankton communities, representing 14 copepods, 4 cladocerans, 1 protozoan, 1 chaetognath and 1 appendicularian were identified. Three species of copepods, Paracalnus indicus, Acartia bifilosa, A. omorii, and Noctiluca scintillans, Sagitta crassa and Oikopluera dioika appeared all the year round. Zooplankton abundances varied between 530-14,388 indiv./m3 and were recored the highest value in June and lowest in August. According to the dominance of small -sized inlet water copepods, the seasonal occurrence of cladocerans and high abundance of N. scintillans in summer, the studied waters showed to be one of typical waters in neritic zones of the Yellow Sea.

開化期 韓國女性의 近代意識의 形成

This paper attempts to trace the process of formation of Korean Women's "modern" consciousness and to indicate how it started to grow. Since the 17th century the voluntary modernization effort had been pursued by the followers of practical science. However, the effort had met with failure. The effort began to be realized in the 19th century when the Korean government partially perceived the necessity of modernization and opened her door to keep abreast with the other nations of the world. Korean women came to be enlightened by those who had the chance to be in contact with new knowledge and things, by the introduction of Christianity, and by modern education for women in so-called mission schools. The Kaap-O Reform in 1894 brought changes to all walks of life. The political and economic system of the country together with the social one began to be changed. Accordingly, the enlightenment penetrated the family system, people's social standing, government official's social privileges and so forth. The change was, more or less, an expected outcome of the social needs of the period. In the name of women's beauty and virtue, any remarriage of women was strictly forbidden. However, the custom was abolished with the reform. On the other hand, early marriage of women was forbidden. Although schools were open to common people at the time, no one paid any particular attention to the necessity of educating women. Women made a complaint against the government, and with men took part in the patriotic civil rights movement of the Manmin-Kongdong-Hoi)"All the people getting together society") and tried to oust the incompetent ministry and to establish a reform cabinet. Thereafter, as Japan expanded her aggressive forces, the women's rights movement together with the movement for restoring the sovereignty of Korea was developed. The women's consciousness in this crucial situation complemented the patriotic movement at this time. In 1905, when Korea was deprived of diplomatic rights by Japan, The women's patriotic consciousness was enhanced. They established women's organizations, schools for women, and actively participated in the Kukchae-Posaang Movement("National debt redemption movement") with men. The purpose of the above-mentioned movements was to save the country from crisis and to produce capable women who could do a big part in safeguarding the country. The Korean women's movement is quite different from its western counterpart in the sense that the women's movement in the West has been launched against men. The "enlightened" Korean men have supported and welcomed Korean women's "modern" consciousness, since the friction between the two sexes had to be dissolved in the face of the much bigger task loaded on their shoulders, the protection of the sovereignty of their country from the enemy outside.
