환경감마선량 변동을 감시하기 위해 한국원자력연구소 부지 주변에 온라인 감마선량 감시망을 구성하였다. 모니터링 포스트에 설치된 전리함 검출기에 의해 측정된 자료는 무선전송방식으로 중앙통제소에 전송되어 실시간으로 감시된다. 무선전송 방식은 자료의 전송, 처리 및 자자에 신뢰도가 높고 경제적이었다. 감시시스템은 급격한 선량증가시 조기경보체제와 연결할 수 있게 하였다. On-line gamma monitoring system around KSERI-site was set up to monitor the radiation fluctuations in environment. Data on gamma exposure rates measured by the ionication chamber in the monitoring posts are transmitted to a computer of central control station with radio telemetry transmission and reliable on handing and storing of data. This monitroing system can triger an early warning system in the event of abnormal radiation levels.

熱帶豆科作物 Winged Bean (Psophocarpus tetragonolobus(L.) DC.)의 定植期와 收量

李龍三,尹晟鐸 濟州大學校 亞熱帶農業硏究所 1989 亞熱帶農業硏究 Vol.6 No.-

本 試驗은 TPT-8, UPS-63을 공시하여 定植時期에 따른 winged bean의 種實收量과 green pod 收量 그리고 이들의 수량구성요소를 조사하여 적정 정식기를 구명코자 시험하였던 바 그 결과를 요약하면 다음과 같다. 1. 種實收穫區 및 green pod 收穫區 모두 開花所要日數는 정식일이 늦을수록 단축되는 경향이었으나 開花期는 거의 비슷하여 長日性植物로 판단되었다. 2. 定植期間 種實收量을 보면 5월 30일 定植期가 가장 수량이 많았으며 같은 정식기의 UPS-63이 185kg/10a로 가장 수량이 많았다. 3. 定植期間 green pod 收量은 5월 30일 定植期가 가장 수량이 많았으며 가장 수량이 많았던 구는 5월 30일 정식구의 TPT-8로 1834.3kg/10a이었다. Two varieties, TPT-8 and UPS-63 with three transplanting date of May 1, May 15 and May 30 were tested to determine optimum transplanting date of winged bean (Psophocarpus tetragonolobus (L.) DC.) in relation to seed yield and green pod yield. The results obtained are summarized as follows; 1. Days from planting to flowering were shorter as transplanting date got later in both seed harvest trial and green pod harvest trial. But flowering date was about the same time, indicating that winged bean is long-day plant. 2. Among transplanting dates, May 30 transplanting date yielded the highest seed yield and UPS-63 in the same transplanting date showed the highest seed yield by 185.0kg/10a. 3. Among transplanting date, May 30 transplanting date also yielded the highest green pod yield and TPT-8 in the same transplanting date obtained the highest yield by 1,834.3kg/10a.

정책북한의 대외교역 구조적 특징

이원복,이용삼 국제무역학회 2001 국제무역연구 Vol.7 No.2

북한의 대외경제정책은 국가독점의 원칙, 자급자족경제의 원칙에 입각하여 자립경제 건설의 완성을 위한 보조적 수단으로 간주해 왔으므로 무역의존도는 높지 않았다. 따라서 자립적 민족경제 건설을 상위개념으로 경제발전에 꼭 필요한 상품을 수입하고 그에 필요한 외화를 얻기 위해 상품을 수출하는 것을 기본으로 하고 있다. 그러나 사회주의권의 붕괴로 대외경제협력의 기반이 상실돼 대외무역액이 급격하게 감소하게 되고 북한의 주요 원조국이었던 러시아와 중국마저 구상무역에서 경화결제로 전환함에 따라 북한은 대외무역의 중요성을 점차 인식하게 되었다. 북한은 이러한 경제난을 극복하기 위하여 개방과 개혁을 통한 대외관계 개선으로 교역규모를 확대하고 있다. 북한의 대외교역 규모는 2000년도에 전년대비 33.1% 증가하여 북한경제의 회복을 보여주고 있으며 교역상대국의 다변화를 위하여 노력하고 있으나 수출입물자를 수송할 인프라구축이 열악하여 수송이 용이한 아시아, 유럽과의 교역이 98.5%로 지역별 편중이 심한 무역구조를 가지고 있다. 국가별로는 중국, 일본이외에 태국, 인도 등의 동남아시아 국가들과의 교역이 급속히 증대되고 있다. 그리고 북한의 주요수출상품은 섬유, 전기·전자, 기계류, 수산물, 비금속, 광물, 플라스틱, 농임 산물 등이며 주요수입상품은 기계 및 전기·전자, 섬유, 에너지물자, 식량, 운송기기, 플라스틱, 화학공업제품 등으로 구성되어 있다. This paper represents the structural characteristics on foreign economic policy of North Korea by analyzing the status of trade and relations with foreign countries. The trade dependence of North Korea has not been high until 1980's before destroying socialism system since they import only necessary commodities for building self-economy. However the economic conditions of North Korea have the experience of minus growth and serious difficulties economically which is caused due to inefficient economic policy and due to destroying socialism system. Therefore this paper analyzes the current status of trade and structural characteristics of North Korea to understand how they are going to overcome their difficulties economically by opening economy positively.

Although the Working Formulation is commonly used to classify NHL in Korea, it has been recognized as imperfect for primary extranodal lymphoma, expecially for patients with nasal, paranasal disease because of their histological characteristics. Angiocentric T/NK cell lymphoma remains rare clinical presentation in North America and Europe but is more common in Asia and Latin America. The optimal mode of treatment has also not been decided on, probably because of their rarity and limited understanding of its natural course. The aim of this study was to analyze our experience with 14 patients with angiocentric lymphoma seen at the Chungnam Natioanl University Hospital over the last 5 years. We reviewed the records of 14 patients who were treated at the Chungnam National University Hospital between January, 1996 and December, 2000. The angiocentric T/NK cell lymphoma accounted for about 8.2% of NHL. The median age was 52.5 (range 36-71) years. Sex ratio was equal. According to the Ann Arbor staging system, disease was classified as stage Ⅰin 3 patients, stage Ⅱ in 8 patients and stage Ⅳ in 3 patients. Systemic B symptoms were present in only four patients in only four patients. All patients has extranodal involvement. The most frequently involved extranodal sites were nasal cavity followed by paranasal sinuses and orpharynx. The most common presenting symptoms were nasal obstruction with purupent rhinorrhea followed by dysphagia. According to the International prognostic index (IPI), most patients was in low-risk group (11 patients). Nine patients responded completely. Seven patients were received combination chemotherapy and 2 patients had radiation therapy as a initial treatment. Five patients were relapsed. After a median follow-up of 660.5 days, the overall survival and disease-free survival rates at 3 years was 56.8% and 42.9% respectively. The median survival time was not yet reached. The median overall survival time was 1338.5 (range 1212-1564) days for non-relapsed and 733.4 (range 302-1008) days for relapsed patients. The median time from CR to relapse was 100.5 (range, 39-159) days. There were limitations to know enough about the characteristics of angiocentric T/NK cell lymphoma because of a small number of patients. In the future, multicenter trials will be neccesary to identify clinical characteristics, optimal treatment mordalities and their responses, and prognostic factors.

交通安全을 위한 道路管理 方案

李勇宰,오주삼 中央大學校 建設環境硏究所 1994 環境科學硏究 Vol.5 No.-

The need for efficient systems for managing road pavements and structures is growing, as maintenance activities continue to gain in importance compared with new road construction, and competition for available funding and environmental awareness both increase. In addition, the growing interest of traffic safety and traffic volumes and the ageing of the existing infrastructure create the need to develop effective strategies for reconstruction and marginal increases in capacity to avoid uneconomic reduction of the service conditions on existing roads. Road management thus has to be understood to include not just the maintenance of the original conditions of the road, but also the improvement of its characteristics such as traffic safety in order to satisfy the increasing requirements at a satisfactory level of service. The objective of thesis is to suggest policies related to the improvement of traffic safety by an efficient road management. Thus the road management policy becomes capable of shaping the technical standard and policies, and balancing the financial demands of both maintenance and improvements of traffic safety.

韓國經濟開發計劃과 財政의 役割 : 1962∼'71

李龍三 大邱大學校 社會科學硏究所 1998 社會科學硏究 Vol.5 No.1

韓國은 1960年 1人當 GNP가 $79에 불과한 빈곤한 國家였으며 그때의 輸出은 $3,290만 인데 輸入은 그 10培인 $35,400만이었기 때문에 外國의 資本이 없으면 經濟活動을 제대로 할 수 없었다. 이와 같이 美國을 비롯한 외국의 援助가 감소됨에 따라 政府는 外國의 資本을 도입하는 經濟開發5個年計劃을 세워 自立經濟의 確立을 목표로 하였으며 이러한 經濟開發計劃을 성공시키기 위해서는 무엇보다 財政運營의 役割이 중요하였다. 특히 經濟開發에 중점을 둔 財政投融資 活動은 경제성장에 지대한 영향을 미쳤다고 할 수 있다. 따라서 본 논문에서는 한국경제개발계획에 있어서 중요한 기능을 한 재정의 경제적 역할을 살펴보고자 하는 것이 목적이다.

이윤영,유관희,김삼용,안병준 충남대학교 암연구소 1991 癌共同硏究所 硏究誌 Vol.1 No.1

Using the colorimetric [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT)assay, we evaluated the chemosensitivity of 8 anticancer drugs{vincristine(VCR), vinblastine (VBL), adriamycin(ADR), cisplatin(CPDD), etoposide(VP-16), cytosine arabinoside(ara-C), bleomycin (Bleo) and cyclophosphamide(CYC)} and the cytotoxicity-enhancing effects of (±)-ar-turmerone and the extracts of the crude drugs {Lithospermum erythrorhizon(LE) and Scutellaria baicalensis (SB)} on the above mentioned anticancer drugs against HL-60 and KG-1 cells among 8 anticancer drugs, VCR, VBL, ADR, and CPDD inhibited the growth of both cell lines by more than 50%, while VP-16, ara-C, Bleo, and CYC were less effective. (±)-ar-Turmerone had significant inhibitory effects against both cell lines, showing the ID_(50) values of 11.730 μg/ml and 0.292 μg/ml for HL-60 and KG-1 cells, respectively. But the extracts of LE and SB roots showed no significant cytotoxic effects. According to ID_(50) values, the cytotoxicities of VCR, VBL and ADR against HL-60 were enhanced two, eight and three times by mixing (±)-ar-turmerone, five, seven and three times by adding the extract of LE root, and twenty, six and three times by mixing the extract of SB root, respectively. The cytotoxicities of the above mentioned drugs against KG-1 cell were enhanced two, seven and three times by mixing (±)-ar-turmerone, two, three and three times by combining wilth the extract of LB root, and two, five and two times by adding the extract of SB root, respectively. The cytotoxicity-potentiating effects of (±)-ar-turmerone and the extracts of LE and SB roots against HL-60 cell were greater than KG-1 cell.
