동복호의 수중생태계 구조를 파악하기 위한 조사의 일환으로 상류, 중류, 하류의 식물플랑크톤의 출현패턴을 조사하였다. TN과 TP농도의 조사지점과 조사시기에 따른 변화는 5월을 제외하고는 크지 않았다. 클로로필의 농도는 상류와 중류에서는 8월에 가장 낮고 봄과 가을에 높은 것으로 나타났고, 하류에서는 5월에 최고의 농도를 나타냈다. 동정된 식물플랑크톤은 상류에서 78종, 중류에서 71종, 그리고 하류에서 63종으로 총 108종이었다. 녹조류가 54종, 규

하천식물의 자연환경조건을 규명하기 위하여 국내 중소규모의 10개 하천(한강수계의 문산천, 곡릉천, 낙동강 수계의 미천, 쌍계천, 남천, 북한강 수계의 가평천, 조종천, 남한강 수계의 청미천, 양화천, 복하천)을 선별한 다음에 각 하천의 전 유로연장에서 가장 자연성이 높은 구간 1km를 중점조사구로 결정하였다. 그리고 그 구간에 대하여 2004~2007년 여름에 식물조사를 belt transect 방법으로 실시하였다. 그 결과 총 296종이 출현하였는데, 그 중에서 출현빈도가 높은 121종과 대상지의 환경인자(저수로 물로 부터의 거리, 하상재료의 크기, 사주의 개수, 대상지의 고도, 하상경사, 저수로의 폭, 하천수질측정값)간의 RDA (Redundancy analysis) 및 피어슨의 상관성 분석을 실시하였다. 그 결과 대입된 식물종들은 대상지의 고도, 하상경사, 사주의 개수의 인자와는 유의성이 없었으나, 하상재료의 크기, 저수로의 폭, 전기전도도와 인산염인(PO4-P)의 농도와는 상관성이 “매우 높은~보통”으로 분석되었다. 그리고 이 식물들은 현재의 그들의 수환경 조건을 그대로 반영하고 있기 때문에 분석방법의 신뢰성에 큰 무리가 없으나, 사례의 다양성 부족으로 다른 사례하천으로의 확대해석은 어려울 것이다. 그러나 본 자료는 앞으로 하천특성에 따른 식물연구나 하천식물 선정을 위한 기초 자료로는 이용할 수 있을 것이다.

The underwater sound transmission system(USTS) was experimentally made to monitor the cetacean's appearance by telemetry, and then its system was tested to evaluate its performance from July to October, 2007 at the Kimnyeong berth and the dolphin's breeding ground of Pacific Land in Jeju island, respectively. The results showed that the sweep sound in the trial experiment and the whistle sound of bottlenose dolphin(Tursiops truncatus) were favorably received by telemetry. Therefore, we could confirm the USTS is able to monitor the cetacean's appearance in real time without direct observation at sea within effective range of code division multiple access(CDMA) communication method.

2004년 4월부터 9월까지 총 6개월 동안, 강원대학교 학술림내 연엽산 일대의 딱정벌레목의 출현상을 채집방법에 따라 조사하여 비교하였다. Sweeping에 총35과 151종 690개체가 나타났고, light trap에 30과 148종 689개체가 출현하였으며, 그리고 pitfall trap에는 총18과 112종 1674개체가 채집되었다. 채집방법별 건중량은 pitfall trap (181.46 g), light trap (39.85 g), 그리고 sw

본 연구는 2000년 일부 구간이 자연형 하천으로 복원된 불광천을 대상으로 하여 한 하천 내에 정비방식이 다른 직강화 하천구간과 자연형 하천복원구간으로 구분하여 식물상 및 식물종의 출현빈도를 비교 분석하였다. 조사는 2003년 5월과 8-9월에 걸쳐 이루어졌으며, 식물상은 하천의 양안에 출현한 모든 식물을 동정하여 정리하였고. 식생은 200m를 기준으로 하여 Belt-transect 방법을 이용하였다. 2003년 5월 및 8-9월은 직강화 하천구간에서는 33과 73속 88종의 식물이 출현하였고. 자연형 하천복원구간은 36과 76속 90종의 식물이 출현하였다. 귀화율 (Naturalized Index：Nl)은 직강화 하천구간은 22.7%, 자연형 하천복원구간은 21.1%였고, 도시화지수 (Urbanization Index：Ul)는 직강화 하천구간이 7.8%. 자연형 하천복원구간이 74%로 직강화 하천구간이 자연형 하천복원구간보다 약간 높았다. Belt-transect 조사법에 의한 식물종 출현빈도 결과는 직강화 하천구간에서는 하안에는 여뀌와 환삼덩굴이 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 이에 반해 자연형 하천복원구간에서는 하안에는 갯버들, 여뀌, 소리쟁이. 환삼덩굴이, 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 즉 직강화 하천구간과 자연형 하천복원 구간은 제방에는 구간에 따른 차이가 없고, 하안의 경우에는 자연형 하천복원구간에 도입된 갯버들이 출현하여 차별을 보였다.

Orientalness is a concept that express the collective identity of the Orient in relation to the West. THe concept itself is mutable and defined by the relationship between the two regions art different points in time. Changes in the concept depend on a number of factors, such as cultural influence, the political balance of power between the two regions, and on the interpretative sheme that defines the relationship. In addition, the geographical notion of the concept evolves culturally, socially and politically. During this process, Oriental-ness becomes Oriental-ism art times. I will attempt to survey and measure the progression of Orientalness from its emergence in early 17th century to its subsequent tranformation in modern Korea as reflected in art theory and art works. The recognition of the comparative characteristics of Oriental art began when the Orient was exposed to the art of the West in the late Ming dynasty during the early 17th century. The changes in the artistic climate in China affected the late Chosun. I will start with a brief introduction of this time and the birth of Orientalness. The concept gradually changed during the period of Enlightenment(開化期) towards the end of the 19th century, and during the colonial period(1910-1945) it took on a new form. Establishment of the concept of "Orient" as a single, unifying concept spanning across cultures and national boundaries has been attributed to late Meiji period Japan, whose intention at that time is believed to have been to build a pan-Asia(亞細亞) empire with Japan at its commandinf center. IT has been stressed that the real motive behind the formation of one single cultural unit, where the shared common written language was Chinese and Confucianism and Taoism were the common metaphysical traditions, was to build one political unit. WHen the notion of a geographical unit of Asia was replaced by the cencept of Asia as a cultural and political unit, a massive growth of interest and discourse were provoked around the concept of Orientalism. When Orientalism was being formulated, Korea automatically became member of "one Asia" when the country became colonized. For Koreans, the identity of the Orient had ti be defined in ciltural terms, as the political notion of a nation was non-existent at that time. THe definition if udentity was pursued at two levels, pan-Asia and local. If Orientalism was an elite discourse centered in pan-Asian philosophical and religious trditions, localized Orientalism was a popular dis-course emphasizing locality as the byproduct of natural geographic condition. After the liveration in 1945 from colonial rule, a thrust of movement across towards political nationalism. Two types of discourses on Orientalism, elite and popular, continued as central themes in art. Despite the effort to redefine the national identity by eradicating the cultural language of the colonial past, the past was enduring well into the present time. As discussed above, even when the paintinf themes were selected from Korean history, the tradition of usinf history paintinf as a manifestation of political policy to glorify the local identity had its founding during the Meiji period. THe elevation of folk art to the level of high art also goes back to the colonial promotion of local color and local sentiment. Again, the succession of the past (colonial) ideal was defended as the tradition assumed a distict modern shape that was abstract in style. The concept of the "Orient" is of relative and changing nature. It was formulated in relation to Western culture or civilization. Whatever the real motive of the adoption of them had been, the superiority of the Orient was emphasized at all times. The essence of the Orient was always perceived as the metaphysical tradition as a way to downgrade Western culture as materialistic. This view still prevails and the principle of Orient was always sought in Confucianism, Taoism, and Buddhism. Even when Orientalism was employed by imperialist Japan in an effort to establish her position as the center of the Orient, the spiritual source was still in Chinese philosophy and religion. In art also, the Chinese literati tradition became the major platform for elite discourse. Orientalism was also degined locally, and the so-called local color was pursued in terms of theme and style. Thus trend continued despite the effort to eradicate the remnants of colonial culture long after the aesthetic ideal of the modern Korean art.

In order to investigate the properties in distribution and movement of anchovy school catches by the lift net in the Kamak bay and their relation to the environmental factors, I. e., the amount of chlorophyll-a and turbidity were observed from June to August in 1997 and compared with the catch of anchovy by the lift net. The results obtained are summarized as follows;1) The amount of chlorophyll-a ranged from 4.0 to 12.0 mg/m3 on July and from 3.0 to 15.0 mg/m3 on August in horizontal distribution, the amount of chlorophyll-a ranged from 3.0 to 8.0mg/m3 on June, from 5.5 to 11.6 mg/㎥ on July, and from 6.0 to 11.1 mg/m3 on July and from 1.0 to 6.0ppm on August, respectively. 2) Anchovy school can be presurmed, they are come from north of bay, visited and distributed through east of bay at the middle of June. Moreover, they spreaded in all bay. Then gradually, when July arrive, they go to the south the nearest the coasts, and they are outflow through the south entrance of bay at the end of August.3) The catch of anchovy was highest on July, poor second on August, and lowest on June. The chlorophyll-a and the turbidity influenced remarkably on the distribution and movement of anchovy school and the influence of chlorophyll-a was alrgest.

This study was carried out to determine the sex of genomic and embryonic DNA using polymerase chain reaction(PCR). Bovine specific(216bp) and Y chromosome speicific DNA primers(l4lbp) were synthesized and tested for sexing. Bovine embryos used in this study were produced by in vitro fertilization. Few blastomeres for PCR were bisected by nicromanipulator and demi -embryos were cultured in TCM 199 medium containing 0.1% of solcoseryl. The results obtained were as follows; 1. Average optical density of genomic DNA extracted from blood of Hanwoo was 1.79 0.14. 2. 2. The ratio of the demi-embryos developed to blastocyst was 62.1 and 81.9% in morula and blastocyst, respectively. 3. When DNA of 2~4, 5~10 and more than 11 blastomeres was amplified with Y chromosome specific DNA primer by PCR, appreance rate of Y specific DNA band was 16.7, 46.2 and 40.0%, respectively. At least 5 to 10 blastomeres were required to determine the sex of embryos. 4. The rate of demi-embryos developed to blastocyst was 73.3% in TCM 199 medium supplemented with 0.1% solcoceryl. but 55.6% in control.
