강영호,Kang, Young-Ho 한국생태학회 2003 Journal of Ecology and Environment Vol.26 No.6

Historical Documents on Proper Tree Selection System of Korea were collected in Japan and introduced in this review. Products of some pine species and fruit were used for laying a tribute to Kings in the Chosun dynasty. In this review, some case studies and implementation of proper tree selection system during the period of Japanese rule, the atlas of climatically favourable regions for the species of trees and bamboos in Korean peninsular, and the test results on regional afforestation, tree selection and proper tree selection of fast growing trees were introduced. Of these documents, especially, the atlas of climatically favourable regions of trees and bamboos growing in Korean peninsular is considered as a valuable document. It tis expected that these historical documents on proper tree selection system might be use as references for the researches on indigenous forest, forest resources development, afforestation of fire damaged areas, and the restoration project of North Korea by the time of reunification of Korea. 이 논문에서는 우리나라 적지적수 연구사에 관한 사료를 제시하였다. 필자는 조선시대의 임금에 대한 진상을 목적으로 한 적지적수사와 일제강점 초기의 간이적인 적지적수 연구 및 실시사례, 강점중기에 이르러서는 조선수목죽류 기후상적지도, 후기에는 속성수의 절지식재시험 및 지역별 조림수종 선발시험 등에 관한 주요 자료를 해외에서 수집 발굴하였다. 조선수목죽류 기후상적지도는 아직까지 국내에 알려지지 않은 자료로서 향후 우리나라 산지의 지원화 및 산불 피해지 복구조림, 남북통일을 대비한 북한지역 녹화사업의 기초자료로서 뿐만 아니라 고유임상 및 식생연구 등에도 유용하게 사용될 것으로 기대된다.

The optimum etching condition of allyl diglycol carbonate (CR-39) for detecting the 60 MeV N-ions was determined as $70^{\circ}C$, 20% NaOH for 130min, by considering the variations of track density and diameter. Under these conditions, the maximum detectable track density was $1.7{\times}10^7tr/cm^2$. Track densities were linearly increased with increase of the total charge of the incident 60 MeV N-ions. By considering the scattring of N-ions as the Rutherford elastic scattering of point source, the measured relative probability was well consistent with the calculated value. The detection efficiency of CR-39 was in the range of 54-41% for 60 MeV N-ions of 12 nC-100 nC. Allyl diglycol carbonate(CR-39)에 조사(照射)된 60MeV의 질소이온을 검출하기 위한 최적부식 조건을 부식시간에 대한 비적밀도와 비적직경의 변화를 고려하여 $70^{\circ}C$, 20% NaOH 용액에 대해 부식시간 130분으로 정하였다. 이 조건에서 검출가능한 최대비적밀도는 $1.7{\times}10^7tr/cm^2$였으며 입사(入射)된 질소 이온의 총전하량의 증가에 따라 비적밀도가 선형적으로 증가하였다. 또한 $2{\mu}m$의 금박에 의한 질소 이온의 산란을 점선원(點線源)에 의한 Rutherford 산란으로 고려함으로써 측정된 상대산란확률이 이론치와 일치하여 선량측정이 가능하였으며 $12nC{\sim}100nC$의 입사(入射) 질소이온의 전하에 대해 $54{\sim}41%$의 검출 효율을 얻었다.

Objectives : To determine the prevalence, pattern. and out-of-pocket expenditure of complementary and alternative medicine (CAM) utilization in Korean adult population. Methods : We conducted a representative telephone survey of 2,042 persons aged 18 or older. Data about any health problem, details of their use of medical doctors(MDs) offices/hospitals/pharmacies services and CAM during the preceding 12 months were collected with structured questionnaire. Results : The utilization rate of CAM among Korean adults was 29% in one year. A total of 231 kinds of CAM was identified from this survey. Annual out-of-pocket expenditure associated with CAM use in 1998 amounted to ${\xi}{\S}1.88$ billion and was comparable to 40.8% of out-of-pocket expenditure paid for MDs offices/hospitals/pharmacies services. Among those(N=424) who paid for both MDs offices/hospitals/pharmacies services an d CAM, 35.8% paid more for CAM. CAM gave more satisfaction than western medicine to those who had experience of both types of therapy. About half of CAM users were willing to recommend CAM to others. Disclosure rate to physician among CAM users was not high(40.6%). Conclusion : CAM became a popular source of health care in Korea, Korean spent a substantial amount of out-of-pocket money on CAM without any public control. Because CAM use is likely to be increased rapidly through lay referral system, health policy makers and health professionals should pay more attention to CAM for making appropriate utilization of CAM.

흑연음극을 이용하여 LiCl-KCl공융염내에서 금속우라늄의 전해정련을 수행하였다. Uraniurn-Graphite Intercalation Compound(U-GIC)의 형성에 의하여 우라늄 전착물의 sell-scraping이 일어나며 전해정련에서 stripping과정을 생략함으로서 전해효율을 높일 수 있다. 우라늄 전착물내의 희토류 원소 오염은 무시할 만 하였으나 약 300ppm정도의 탄소가 오염되어 있는 것으로 관찰되었다. 탄소 오염은 이트륨을 이용한 정제공정 등을 거칠 경우 제거 가능하리라 사료된다. 회수된 우라늄 전착물의 조직 특성을 분석하였으며, 스틸 음극에 의해 회수된 전착물과 비교하였다. 이 결과는 초기 실험결과 이며 보다 심층적 연구를 통하여 사용 후 금속핵연료의 전해정련 개념을 개선시킬 수 있을 것으로 판단된다.

Globally, cancer research has been considered one of the most important field of biomedical researches. Recently, in Korea, there are increasing concerns about cancer research and the development of national cancer control programme. For the efficient investment in cancer research at the national level, strategic approach is needed based on the nationwide information about current status of research. However even the basic data on cancer research have not been systematically collected, and are not available when necessary. The aim of this study is to assess current status of cancer research. For this purpose, this study applied two round Delphi method in which fifteen experts in cancer research fields participated. They rated each items on the initial list at the first round, and modified their responses at the second round. Panels responded that pathogenesis of cancer, research & development of cancer drug, and oncogene, etc. are the most urgent and important research Holds. They assessed national level of cancer research as being 49.6% of the world highest level. Coefficient of variation tended to be lowered with the iteration. Predictive stability was evaluated to be lower in items of urgency than in items of importance and research level. Although this study shares the same limitations in the selection of the experts with many other Delphi studies, it provides a primary data that would be required to plan the national strategy of the cancer research.

저준위 방사성 액체폐기물의 새로운 감용방법으로써 cellulose acetate막을 사용한 투과증발법의 연구가 수행되었다. 실험결과에 의하면 일반적으로 유기물의 분리에 사용되는 투과증발법은 액체폐기물의 감용을 위한 제염효과가 우수하였고, 수분의 증발속도도 저준위 방사성 액체폐기물의 감용을 위해 널리 사용되는 자연증발에 비해 현저히 빨랐다. 또한 주입용액의 조건에 따른 실험결과를 토대로 투과증발특성을 평가하였으며, 투과증발량을 증가시키기 위해 cellulose acetate막의 최적제막조건을 설정하였다. As a promising method for the volume reduction of the low-level liquid waste, the pervaporation process was studied using a cellulose acetate membrane. Experimental results showed that the pervaporation method, usually applied to separation of organic materials, has a good decontamination effect for the volume reduction of liquid waste and the evaporation rate of water in this process was markedly faster than that of natural evaporation method, a wide-used process for the volume reduction of liquid waste. Depending on the feed solution conditions, the pervaporation characteristics were evaluated by the experimental results and the optimum conditions for preparation of the cellulose acetate membrane were established to increase the pervaporation flux through the membrane.

우리나라는 현재 농촌인구의 지속적인 감소와 고령화 등으로 농업 생산에 많은 문제점이 발생하고 있다. 특히 노동력 부족은 농업중심의 지방자치단체에서 극복해야 하는 최대 숙제가 되고 있다. 이에 최근 고도화된 디지털기술 기반의 드론, 센서, 로봇 등을 활용한 효율적인 농업이 빠르게 확산되고 있다. 본 연구는 벼 재배시 육묘·이앙 작업 등 노동력 절감하기 위한 드론을 활용한 벼 항공직파 시 파종기의 살포형태에 따른 벼의 생육특성을 조사하였다. 본 시험은 김제시 광활면의 간척지 벼 재배포장에서 수행하였다. 시험품종은 예찬벼(천립중:26.8g)를 활용하여 22년 5월 19일에 파종량 4kg/10a 수준으로 파종하였다. 파종시 8엽기(21inch) 농업용드론에 원판회전식 입제살포기와 농촌진흥청에서 개발 중인 직분사식 파종기를 각각 부착하여 5m/s 내외의 비행속도, 2.5m 살포고도(유효살포폭: 3~5m), 살포기 개폐율 70~100%의 살포조건으로 진행하였다. 시비, 병해충 방제 등 기타 재배는 농촌진흥청 벼 표준재배법에 준하였다. 파종량에 따른 ㎡ 당 입모수는 직분사식 정밀파종기가 원판회전식 입제살포기 대비 평균 13.7개 많은 것으로 조사되었다. 파종된 종자의 분포정도를 조사한 결과 원판회전식 형태는 좌측으로 종자가 편중된 경향을 보였으며 직분사식 형태은 비교적 균일하게 파종되었다. 변이계수 분석결과 직분사식 파종기가 원판회전식 입제살포기 대비 7% 이상 향상된 것으로 나타났다. 벼 출수기는 8월 19일로 동일하였으며 ㎡당 수수는 390-420개로 조사되었다. 수확 후 수량 및 수량구성요소, 품질 등에 대한 조사를 진행할 예정이다. 직분사식 파종기의 단위시간당 작업량, 정밀도 등 농작업 효율 등을 개선하고 벼 항공직파에 대한 매뉴얼을 정립한다면 대규모 간척지 또는 들녘 등 실용화가 가능 할 것으로 판단된다.
