Volatile organic compounds in the ambient air were gathered irregularly by normal temperature concentrating method at Odea-ri and Oceon-ri Ulsan-gun in the neighbourhood of Ulsan Petrochemical Industrial Complex and analyzed with gas chromatograph. Several hydrocarbons in common aklospheric air or emitted fugitively from the chemical plants were identified and quantified by comparison with the retention times of standard compounds. The results from several field surveys in 1992 show that the concentrations of styrene at residential area of Odea-ri and Ocheon-ri were less than 0.4 ppm, but once a while greater within the chemical plants area. When it smelled unpleasantly in these area, the concentration of hydrocarbons were also high. It was concluded that the close and long-term investigation about other odorous components but hydrocarbons will be necessary to ascertain the cause of unpleasant odor of these area.

Cerithiid specimens collected in South Korean waters (12 localities) during the period from August 1965 to October 1991 were identified and classified. In the present study, seven species in six genera were identified as Korean Cerithiidae. Among them, three species, Blttlum variegatum Kuroda and Habe, 1971, Brttrum cratlculatum Gould, 1860 and Ataxocerlthlum abnormale (Sowerby, 1903), are new to Korean malacofauna and fully redescribed with illustrations.

우리나라 배전전압은 1917년 경성전기주식회사가 표준 배전전압으로 3.3kV를 채택한 이래 1960년대 중반까지는 3.3kV, 5.7kV-y, 6.6kV이었다. 1965년 10월, 경북 칠곡군 약목변전소 관내의 당시 박정희 대통령 생가 인근을 통과하는 22kV 비접지 송전선로 9km에 다중접지된 중성선을 추가시설, 3상 4선식 배전선로화하여 4개부락 40kV의 부하를 공급함으로써 우리나라에 22.9kV-y 중성선 다중접지 배전방식 도입의 효시가 된 이래, '22.9kV-y승압'사업은 1970년부터 1986년까지 한전의 배전분야 최우선사업으로 전국 방방곡곡에 걸쳐 시행되었다. 이제는 서울 일부와 제주도에서만 시행중으로 종료단계인 오늘에 이르기까지, '22.9kV-y승압'은 한전의 본사와 전국의 사업장에서 수많은 배전분야 종사자들이 총력을 기울여 이룩한 세계 전력 산업사에 그 유례가 드문 격상에 의한 배전전압 단일화 사업으로써, 배전사업 현대화의 중심사업이었다 하지 않을 수 없다.

1. As the low standard of living of the people who live in both the model and compared villages, is almose similar to each other, the state of their food intaking has nearly the same degree. 2. The villagers of the two kinds of village mentioned above do not cast off their traditional eating habits getting an energy from rice and vegetarian diet. They, however, have been so much interested in the problem of birth control that they have a few children in less than four-year-old. We have to go on the problems of driving a reasonable family plan, and replacing the traditional food life by taking a fatty food. 3. Their pool life forces them to have an over work for supporting their family. Even though they take much Fe from grains and vegetables day after day, Fe does not give a great influence on making Hb (Erythrocyte) in a body. Accordingly most of them have developed symptoms of anemia. This research, comparing with the research results of Ewha University and Seoul Medical College shows much lack of Hb. So it is need for them to take a large quantity of animal protain and make a healthful habit by reforming their food life.

During October-December 1987, chigger mites infested on the striped field mice (Apodemus agrarius cereae) collected at Pochun-gun, Gyeonggi Province and Chinhae city, Kyongnam Province were identified. . 1. Of 171 back-striped mice collected, chigger mites wire found from 58 mice, showing 33.9% of infestation rate. 2. Total 865 chigger mites collected were classified into seven species; Leptotrombidium pallidum (4.3%), L. palpate(23.0%), L. orienpalis(20.2%), L. xetum(19.0%), Neotrombicula tamiyai(32.9%), JV. japonica(0.25%) and Euschongastia koreaensis(0.3%). Though the most dominant species in number was N. tamiyai(32.9% of the total), this species was collected at very limited locality and for a short period. Therefore, most common species in Korea seems to be L. palpale which was found at all localities throughout the whole survey period. L. pallidum which is known as the vector species of tsutsugamushi disease in Korea was collected in a very low number(4.3% of the total chiggers collected). 3. The number of chigger mites infested on a host animal showed great variations from one chigger up to 207 chiggers. The present study has shown that there may be other Leptotrombidium species mite(s) for the vector and host of tsutsugamushi disease in Korea.

Varied opinions have been raised on Sushen's regional activities. These are Hwabuk drift theory, Shandong Peninsula drift theory, Liaotung Peninsula theory and the theory of Eastern Area in Heilongjiang Province. The theory of Sushen Dongbei that Sushen's regional activities are the Eastern Area in Heilongjiang Province is widely accepted in the chinese academia. However, this paper try to criticize the theory of Sushen Dongbei on the basis of archeological data. Prehistoric monuments of the Eastern Area in Heilongjiang Province are Singaeryu remains, Sonamsan remains, Aenggaryeong remains, Seokhoejang remains, Jinheung remains and Aporyeok remains. Residential group in the Eastern Area of Heilongjiang Province lived the economic life of fishing and hunting and were involved with primitive agriculture only in partial area. Its society was patriarchal clan steps of phallocentrism. By considering the cultural exchange between the Eastern Area in Heilongjiang Province and Chinese dynasty, the aspect of cultural exchange in two areas was unascertainable. Therefore, the theory of Sushen Dongbei is a mistake in Chenshou's "Sanguozhi" and nothing but a theory that base on the unified theory of Zhonghua minzu and the nationalistic intention in China.

본문은 동북 3성의 지리, 역사, 연구 상황을 개술하고 착중하여 조선족이 동북 3성에 이주한 시기를 4개기로 나누어 그 분포 특징을 밝혔다. 4개의 시기는 (1) 함풍-동치년 시기 (2) 광서년 시기 (3) 선통-민국년 (4) 위만 시기이다. 매시기마다 조선족이 동북 3성에 이주한 역사 지리적 배경을 천명했고 당시 조선족의 이주 노선과 분포특징을 귀납하였다. (1) 조선족이 동북에 이주하여 온 노선은 모두 20개 노선이 있었다. 그중 이주 수량이 많은 노선으로는 종성-개산툰-용정 노선, 남양-도문 노선, 만포-집안 노선이다. (2) 압록강 유역의 중간진에서 중국 림강에 들어온 이주민이 가장 일찍 했다면 두만강 유역은 10-20년 더 높다. (3) 동북 3성 조선족 인구밀도는 두만강과 압록강에 가까울수록 크고, 멀수록 작다. (4) 압록강, 두만강 유역에는 평안도와 함경도의 이주민이 많고, 두 유역에서 북쪽으로 갈수록 조선 남부의 이주민이 많다. (5) 동복 3성 조선족은 산지보다 평원에 많이 분포되었는데 동북의 수전개발에 커다란 공헌이 있다. (6) 중국 조선족에 97.1%가 동북에 집중되나, 그중에서도 길림성에 1,811,946명으로서 전국 조선족 총수의 65.8%를 차지하고, 흑룡강성에 452,398명으로서 25.2%를 차지하며, 요넝성은 230,378명으로서 9.0%를 차지하고 있다.(1990년 통계) (7) 도시에 있는 조선족은 모두가 잡거하고 농촌에서는 잡거구도 있지만 대부분은 순 조선족 부락을 이루었다.

The survey of silkworm disease occurrence in autumn rearing season, 1984, was carried out and the results are as follows. 1. The percentage of diseased larvae in the current season was about 17%. 2. Among silkworm diseases, grassarie was predominant, as it took 38.5% of total diseased larvae, followed by muscardine which took 20.3% and flacherie was taken by 11.9% 3. The infection of silkworm larvae with pathogens occurred more at grown larva stages than at young larva stages. 4. The loss of cocoon yield was mainly caused by unsuitable climate conditions and agricultural insecticides applied in the rice paddy fields and fruit gardens near mulberry fields. The cocoon production also was reduced by the failure of silkworm disease control due to the incomplete disinfection of rearing rooms and tools.
