Mosquitoes were collected with light trap at a pig shed in the vicinity of Daegu city from mid-April to the end of November in 1981 and 1982. A total of 12,942 and 118,061 individuals were collected in 1981 and 1982 respectively. The collection comprised 77% females and 23% males in 1981, and 96% females and 4% males in 1982. The catches were classified into following 7 species: Culex (Culex) pipiens pallens, C. (C.) tritaeniorhynchus summorosus, Anopheles (Anopheles) sinensis, C. (C.) vagans, C. (C.) oritntelis, C. (C.) bitaeniorhynchus, Aedes (Aedimorphus) vexans nipponii. The former three species showed distinct seasonal prevalence. Arranged in the descending order in size of the catches, in 1981, Culex (Culex) pipiens pallens was 44.9% of the total collection (at sex ratio of 0.85), Anopheles (Anopheles) sinensis 42.9% (0.05), Culex (Culex) tritaeniorhynchus summorosus 12.1% (0.00). On the contrary, Culex (Culex) tritaeniorhynchus summorosus 70.4% (0.00), Anopheles (Anopheles) sinensis 25.2% (0.05), Culex (Culex) pipiens pallens 4.4% (2.19) in 1982. The monthly percentages of collected mosquitoes to the total collection were 0.1% (in 1981) and 0.0% (in 1982) in May; 3.5%, 1.3% in June; 50.0%, 33.9% in July; 37.1%, in August; 8.8%, 11.9% in September; 0.5%, 0.8% in October and 0.0% in November. As for seasonal prevalence, mosquitoes appeared in May in both years and began to increase in number from the first week of June in 1981, but from the second week of May, ahead of three weeks in 1982. The highest peak time in 1982 was the second week of August, two weeks later than the fifth week of July in 1981. Culex (Culex) pipiens pallens showed the maximum activity for the fifth week of July in 1981, but for the third week of July, ahead of two weeks in 1982. Culex (Culex) tritaeniorhynchus reached the highest peak for the second week of August in both years. Anopheles (Anopheles) sinensis showed the maximum activity for the fifth week of July in 1981, but for the third week of July, two weeks earlier in 1982. The highest peak times of three main species were compared respectively as folows. Culex (Culex) pipiens pallens had the highest peak time in common with Anopheles (Anopheles) sinensis, Culex (Culex) tritaeniorhynchus summorosus showed the maximum activity for the second week of August in 1982.

일본 통산성 ㆍ자원에너지청은 금년초 1985년도 석유유통합리화조사 등의 일환으로서 「석유가스개발가능성조사보고서 」를 작성하였다. 유입LPG의 공급원다양화 방안의 하나로 추진되어 온 동조사는 1982년의 동남아시아를 시작으로, 1983년 중남미, 1984년 북미, 카나다지역을 대상으로 실시되었다. 1985년에는 대일본수출이 기대되고 있는 호주와 뉴질랜드를 대상으로 통산성으로부터 조사위탁을 받은 일본LPG협회가 「석유가스개발가능성조사단 」을 결성, 11월 11일부터 27일까지 현지조사를 실시했다. 이 자료는 일본 「석유정책 」지(86.8.5 및 15)에 실린 동보고서를 번역한 것이다. <편집자 주>

Fishery production of topshell in Cheju-do has been rapidly decreased in the last few years. To investigate the origin of this problem and estimate maximum sustainable yield (MSY) and catch per unit effort (CPUE) of topshell in Cheju-do, a survey has been done ysing the statistical data for 19 years (1968-1986) of topshell production in Cheju-do and data for 3 yea.5 (1984-1986) from an fishery village, Tonggui-ri, Pukcheju-gun, Cheju-do. Maximum sustainable yield of topshell in Cheju-do assumed to be 2,500-2,800 metric tons(M/T) per year. The annual fishery productions of topshell from 1982 to 1986 were 3,368, 3,649, 3,308, 3,136, and 1,400 M/T, respectively. These results show that topshell had been over-fished during 1982 to 1985. Because of the over-fishing, production sharply decreased down to 1,400 M/T in 1986. Total annual production of topshell in Tonggui-ri is a little less than one Percent of that of Cheju-do. To achieve this production, over the half of resistered diving women in this village have been worked. To estimate catch per unit effort of topshell in Cheju-do, it seems better to use the data which is the number of diving women who have been worked for certain period of time than the number of working days in the same period of time.

A retrospective analysis was undertaken of 46 patients who were referred with squamous cell carcinoma of the esophagus during the period of March 1979 through October 1982, and who were treated by curative radiotherapy in the Department of Therapeutic Radiology Seoul National University Hospital. The overall two-year actuarial survival rate was $20\%$ Survival was analyzed with respect to the site of the cancer, its size, radiation dose, and degree of response. Patients with the best two-year survival rate are the ones who had the tumor no of more than 5cm in length $(39.3\%)$ or confined to the upper third of the esophagus $(29.5\%)$. An optimum radiation dose ranged from 1600 to 1700 rets. Patients to complete response had $42.4\%$ of two-year actuarial survival, but those to no response had $0\%$ of survival.

An experimental watershed was selected and sustainable yield was evaluated. The study area(3.89$\textrm{km}^2$) was located in Kyungpook Sangju Yangchon-dong. The visual MODFLOW was verified by comparing the observed and estimated groundwater table. The analysis of the observed and estimated groundwater table from 19 March 2003 to 18 March 2004 showed that the average error was 0.0009m, the error sum of squares 7.245$m^2$, absolute mean error 0.094 m, root mean square error 0.141m, and the model efficiency was 92%. The normal, 10- and 30- year drought frequency years were selected and sustainable yield was evaluated in these periods. Ratios of sustainable yield to the annual infiltration were 14.5% for the normal year(1992), 15.1% for the 10-year(1994), and 15.2% for the 30-year drought frequency year(1982). The results of this study can be used as a basic information for groundwater development and management planning considering regional characteristics.

Measurement of the radon concentration close to the ground surface can be used in search of environmental radiation for human safety, exploration for uranium, premonitory signals from earthquakes. We can detect radons in soil gas by alpha particle track method using the plastic track detectors, cellulose nitrate (LR115-Type 2 and CA80-15, Kodak $Path\'{e}$) and CR-39. For present works, radon cups having these detectors were made in our laboratory and their conversion factor was determined. A typical conversion factor was $1tr/cm^2{\cdot}30days=1.2{\times}10^{-2}pCi/l$. In the radon cups, some of $CaSO_4$ were used as desiccant for reducing the moisture effects on plastic track detectors. With these radon cups, underground radon concentrations of Kyungpook area were measured. Average radon concentration in Daegu from Jan. 1981 to Feb. 1982 was 39.7pCi/l. From Aug. 1981 to Feb. 1982, average radon concentrations of Daegu, Angang, Kyungju, Pohang, Chungha, and Andong were 31.8pCi/l, 124.5pCi/l, 127.0pCi/l, 79.1pCi/l, 144.4pCi/l, and 70.9pCi/l, respectively. The results were compared with the environmental radiation measured by TLD method.
