The Revised Universal Soil Loss Equation (RUSLE) has been used in over 100 countries to estimate potential long-term soil erosion from the field. However, the RUSLE estimated soil erosion cannot be used to estimate the sediment delivered to the stream networks. For an effective erosion control, it is necessary to compute sediment delivery ratio (SDR) for watershed and sediment yield at watershed outlet. Thus, the Sediment Assessment Tool for Effective Erosion Control (SATEEC) was developed in this study to compute the sediment yield at any point in the watershed. To compute spatially distributed sediment yield map, the RUSLE was first integrated with the ArcView GIS and three area based sediment delivery ratio methods were incorporated in the SATEEC. The SATEEC was applied to the Bangdong watershed, Chuncheon, Gangwon Province to demonstrate how it can be used to estimate soil loss and sediment yield for a watershed. The sediment yield using USDA SDR method is 8,544 ton/year and 4,949 ton/year with the method by Boyce. Thus, use of watershed specific SDR is highly recommended when comparing the estimated sediment yield with the measured sediment data. The SATEEC was applied with hypothetical cropping scenario and it was found that the SATEEC can be used to assess the impacts of different management on the sediment delivered to the stream networks and to find the sediment source areas for a reach of interest. The SATEEC is an efficient tool to find the best erosion control practices with its easy-to-use interface.

National Agricultural Pesticide Risk Analysis (NAPRA) World Wide Web (WWW) 시스템(http;l//danpatch.ecn.purdue.edu/∼napra)은 다양한 영농방법에 따른 농약과 영양물질의 지표수/지하수 유실량을 웹에서 모?하고자 개발되었다. 단일 토양에 대해서 모의할 수 있는 Single Field 버전의 많은 기능이 개선되었고, 행정구역/수계 경계에 대해서 모의할 수 있는 County/Watershed 버전을 확장시켜, Web Geographic Information Systems (GIS) 버전의 NAPRA 시스템을 개발하였다. Web GIS 틀을 이용하면, 모의하고자 하는 지역을 마우스로 디지타이징 한 후 그 지역에대해서 영농방법에 따른 영향을 모의할 수 있다. 모의결과를 웹브라우저를 통해서 지도로 보여줄 뿐만 아니라, 그 결과를 데스크탑용 CIS에서 사용할 수 있는 포맷으로 제공한다. 모델을 운영하기 위하여 방대한 양의 입력자료가 필요하고, 일반 사용자가 준비하기 힘든 데이터들이 있는데, NAPRA WWW 시스템은 이러한 입력자료를 서버측 GIS, 데이타 베이스, 강우 및 온도 모델 예측치에서 추출하여 모델을 운영한다. 또한 모의결과를 방대한 양의 텍스트 파일이 아닌, 차트나, 테입블, 또는 지도형태로 보여주기 때문에, 농부와 같이 전문지식이 없는 사람이 이 시스템을 이용하여 여러가지 영농 방법 중에서 환경 친화적이면서 경제성을 유지 할수 있는 최적관리기법을 찾아낼 수 있다.

L-THIA/NPS to Assess the Impacts of Urbanization on Estimated Runoff and NPS Pollution

임경재,비니드엥겔,김영석,최증대,김기성 江原大學校 附設 環境硏究所 2003 環境硏究 Vol.20 No.-

The land use changes from non-urban areas to urban areas lead to the increased impervious areas, consequently increased direct runoff and higher peak runoff. Urban areas have also been recognized as significant sources of Nonpoint Source (NPS) pollution, while agricultural activities have been known as the primary sources of NPS pollution. Many features of the L-THIA/NPS GIS, L-THIA/NPS WWW system have been enhanced to provide easy-to-use system. The L-THIA model was applied to the Little Eagle Creek (LEC) watershed in Indiana to evaluate the accuracy of the model. The L-THIA/NPS GIS estimated yearly direct runoff values match the direct runoff separated from U.S. Geological Survey stream flow data reasonably. The R2 and Nash-Sutcliffe values are 0.67 and 0.60, respectively. The L-THIA estimated runoff volume and total nitrogen loading for each land use classification in the LEC watershed were computed. The estimated runoff volume and total nitrogen loading in the LEC watershed increased by 180% and 270% for the 20 years. Urbanized areas - "Commercial", "High Density Residential", and "Low Density Residential" of the LEC watershed made up around 68% of the 1991 total land areas, however contributed more than 92% of average annual runoff and 86% of total nitrogen loading. Therefore, it is essential to consider the impacts of land use change on hydrology and water quality in land use planning of urbanizing watershed.

Primary aldosteronism is a syndrome characterized by hypertension, hypokalemia, suppressed plasma renin activity, and elevated serum aldosterone levels. Conn first described it 1955 in association with adrenal cortical adenoma(Conn's syndrome). Today, it can be divided into at least six distinctive sub-groups. The diagnosis of primary aldosteronism is usually suspected when the patient presents with poorly controlled hypertension with hypokalemia. The main issues in the evaluation of primary aldosteronism are to differentiate an adenoma from hyperplasia and to localize the adenoma. Basic hormonal studies and computed tomographic(CT) scanning can be used effectively for that differentiation. An adenoma is one of a few potentially curable forms of hypertension, and it is best treated by removing the adrenal tumor. We experienced a case of a typical adrenal adenoma. The patient was a 37-year-old male who had experienced in both his legs over a period of several days a weakness due to hypokalemia. He was diagnosed using basic hormonal studies and adrenal CT scanning. After, he received laparoscopic adrenalectomy and was discharged with improved condition.

For the study of TIS21 protein, a primary response gene product, we produced affinity-purified antisera against recombinant TIS21 protein. At first, hexahistidine-tagged recombinant TIS21 protein was produced by using bacterial expression system and was purified to near homogeneity using Ni^(2+)-affinity column in the presence of urea. PBS-soluble and -insoluble TIS21 protein fractions were immunized into rabbits after dialysis. High-titer antiserum was obtained from one of the rabbits immunized with PBS-soluble fraction. Meanwhile, partially purified recombinant TIS21 protein was further purified by preparative SDS-PAGE and it was conjugated with the sepharose resin. The high-titer serum was applied to this affinity column and affinity-purified antiserum was obtained. This affinity-purified antiserum recognized TIS21 proteins expressed in bacteria as well as in mammalian cell when it was used in western blot. In addition, this affinity-purified antiserum recognized a constitutively expressed 40 kDa protein from NIH3T3, B9, C3HIOTI/2 and 293 cell lines. Detection of this protein with the affinity-purified antiserum can be inhibited by recombinant TIS21 proteins prepared by our laboratory and other laboratory. Therefore this 40kDa protein can be an immunologically cross-reactive protein with TIS21 protein.

Tuberculous peritonitis is discovered from sixty to ninty percent of pulmonary tuberculosis patients. Clinical symptoms are nonspecific such as mild fever, weakness and malaise but show tenderness in right lower abdomen and abdominal distension. Diagnosis is confirmed by laparoscopic and pathologic findings. We report a case of tuberculous peritonitis in an 11-year-old boy who was hospitalized because of abdominal distension with pain on right lower abdomen which had developed one day before he came to hospital. Chest X-ray showed pleural effusion on both sides. We did laparoscopic examination and observed diffuse nodular infiltration. In biopsy specimen we observed osseous granuloma and acid-fast bacilli in AFB stain.

In this study, preparation system for elementary school science teacher in Korea and Japan was compared and analyzed. The study is composed of two parts. In the first part, the science curricula for elementary schools of the two nations were compared, and in the second part the preparation systems for teacher were compared. The results are as follows: First, the instructional hours allotted to science in Korea is higher than those of Japan. That is, while in Korea 102 instructional hours are allotted to science in every grade from 3rd to 6th grades, in Japan 70 hours are allotted in 3rd grade to 95 hours in 6th grade. Second, the science teacher-preparation systems of the two nations are differ manly in the courses provided to prospective elementary teacher. In Korea, the system is managed in purposeful, unified, and closed type, while in Japan the system is operated in several types, including parallel, integrative, connection of the undergraduate and graduate levels, and open types. Especially, in Korea the prospective teachers take subjects through relatively straightforward way which lacks of more specialized courses, and in Japan the courses are divided into three ways. including more specialized course for specific areas such as social science and science. which enable the prospective teachers to take the course on their decisions. Additionally, the areas of educational practices are more specifically divided in Japan. These results may have important implications for the preparation of able teachers for elementary science and improvement of quality of science instruction at schools.
