This paper presents the development and application of a riparian buffer zone design model(RBZDM). The model was developed as a decision-making tool for watershed management, by integrating geographic information system(GIS) and analytical hierarchy process(AFIP) theory. Several factors for watershed management, such as pollution removal capacity, land aquisition cost, distribution of point and non-point pollution sources, and possibility of new pollution source location, were analyzed based on AHP theory. The vegetated buffer zone width was designed using GIS-based riparian buffer analysis. The developed model was applied to the Kyoungan Stream watershed, which is an important part of Paldang lake catchment area. The Kyoungan stream watershed was divided into sixteen subbasins. Six of them belong to the main stem, where the model was applied. Ten alternatives of buffer zone width and five hierarchial levels were designed. The relative importance and the relative preference were computed by pair-wise comparison of evaluation criteria given in hierarchial levels. The buffer zone width was determined by linear function of the given alternatives and relative preferences. From this study, it was determined that the six buffer zone widths of Kyoungan main stems would be 1,594, 1,744, 1,856, 1,782, 1,338, 1,780 meter, from upstream to downstream.

The purpose of this study is to suggest optimum size of residents' bedrooms in nursing homes. Bedroom is an essential part of nursing homes because nursing home residents spend most of their times in bedrooms and occupy the largest part of facility area. Therefore it is necessary to set an adequate standard related to resident room area in nursing facilities, which have a great effect on planning longterm care facilities for the elderly. The body dimensions of elderly people and care givers have been collected from the previous study. Based on the body dimensions data, the behaviors of elderly as well as care givers have been analysed. The minimum areas-exclusive of toilets, closets, vestibules and so on - have been proposed from the results of the behavior analysis.

신택순,김선구,강한석,이길왕,조병욱,전해열 密陽産業大學校 農業技術開發硏究所 1998 農業技術開發硏究所報 Vol.2 No.1

본 연구는 제주재래마의 유전적 특성파악과 이를 통한 타품종과의 유전적 특이성을 가지는 DNA 표지인자를 개발하고자 PCR-RAPD기법을 이용하여 제주재래마와 더러브렛, 가고시마의 3품종에서의 다형 band에 대한 특성파악을 실시한 결과이다. 각 품종별로 10두의 혈액을 혼합한 후 분석하였고 200개의 random primer들 중 PCR증폭양상의 재현성을 기준으로 70개의 primer를 선별하였다. 또한 선별된 primer들중 다형성을 9개의 primer를 이용하여 개체별 DNA분석을 실시하였으며 9개의 prkmer에 의해 나타난 15개의 band는 제주재래마 특이 band, 4개는 더러브렛종에 그리고 4개는 가지고시마 재래마에 품종특이 RAPD band가 나타났다. 따라서 RAPD기법에 의해 품종간의 차이를 보이는 표지인자의 개발이 가능할 뿐 아니라 품종간의 특성차이를 보이는 유전인자 개발과 특성파악이 용이한 것으로 평가되었다. This study was carried out using PCR-RAPD technique to estimate genetic characteristics of Cheju Horse (Jorangmal) and to develop the DNA marker for bread identification in horse. Each three horse breeds was represented by pooled DNA from 10 individuals and tested for 200 different random primers for their reproducible PCR pattern. From them 70 primer were selected and 9 primers were used to detect the difference between breeds at the individual level. Fifteen highly polymorphic bands were observed between breeds using 9 primers . Additionally, the 15 most polymorphic bands showed great difference between breeds in their appearing frequencies, implicating their usefulness in the breed discrimination and in the characterization of genetic structure. Therefore, the polymorphism of RAPD could be used in characterizing genomic difference between breeds and some genetic mechanism that give rise to breed disctimination in horse.

이주롱,이석민,한효상,이해혁,이임순,이권해 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.2

목적 : 전자간증 산모에서 초임신부와 다산부 각각의 임상적 특징을 조사하여 비교 분석하고자 하였다. 연구방법 : 1998년 1월부터 1999년 12월까지 2년간 순천향대학 서울병원에서 입원 분만한 임신성 고혈압성 질환 환자중 초임신부 106명과 다산부 50명, 총 150명을 대상으로 임상통계학적으로 조사 분석하였다. 결과 : 분만까지 임신기간의 비교시 초임신부에서는 33-36주에서 17.9%였고 다산부에서는 34.0%로, 다산부에서 조기분만의 예가 의의있게 많았다. 신생아 체중이 2500g 미만인 군이 초임신부군에서는 36.8%였고 다산부군에서는 62.0%로 다산부군에서 더 많았다. 임신성 고혈압성 질환의 중등도를 보면 중증자간전증의 초임신부에서 35.8%와 다산부에서는 44.0%로, 초임신부에 비해 다산부군의 중증 자간전증의 비율이 많았다. 결론 : 중증 임신성 고혈압성 질환이 다산부군에서 더 많았으며 적은 주수에서 제왕절개술을 시행해 출생아의 체중이 초임신부군에 비해 더 작았고 Apgar 점수도 더 낮았다. Objective : To study the clinical differences of primiparous and multiparous preeclamptic patients. Methods : We statistically analyzed 106 primiparous and 50 multiparous preeclamptic patients who were admitted to the Soonchunhyang University Hospital from January 1998 to December 1999. Results : It was statistically found that multiparae were more likely to give premature birth than primiparae: Thirty four percents of multiparae gave birth in the period between the 33rd and the 36th gestational weeks while 17.9% of primiparae did in the same period. Sixty two percents of the newborn babies of multiparae weighed less than 2500g. Among primiparae, the ratio was 36.8%. In addition, more multiparae(44.0% vs. 35.8%) suffered from severe preeclampsia. Conclusion : severe preeclampsia was found more frequently among multiparae. Since they gave birth earlier by cesarian section than primiparae, their babies weighed less and had lower apgar scores.

노경호,송명석,한순구,김재덕,이윤우 한국화재소방학회 2002 한국화재소방학회논문지 Vol.16 No.2

몬트리올 의정서에 의해서 규제받는 Halon-1301과 대체 물질중의 하나인 CO_2의 물성(밀도, 점도, 엔탈피)의 실험식을 구하였다. 문헌에서 얻은 실험값을 이용하여 온도에 대한 회귀분석에 의해서 실험식을 얻었다. 압축인자를 이용하여 온도에 대한 2차 함수로서 밀도에 관한 실험식을 제안하였다. 점도는 온도에 대한 지수함수로 표시되며, 보정인자를 사용하여 사용 온도범위를 확장하였다. 엔탈피는 열용량과 마찬가지로 온도에 대한 2차 함수로 정의하여 나타내었다. 본 연구에서 제안된 위의 실험식의 상관계수는 0.99이상이었다. For Halon-1301 regulated by Montreal Protocol and CO_2 as its alternatives, the empirical equations of density, viscosity, and enthalpy were correlated in terms of temperature. They were obtained by regression analysis from the experimental data in the literature. The empirical equation of density was expressed as compressibility factor by the second- order function of temperature. The empirical equation of viscosity was formulated as a power function, and a correction factor was considered to cover the wider range of temperature. Finally, heat capacity as well as enthalpy were well fitted by empirical form of the second-order temperature. The correlation coefficients of the equations in this work were more than 0.99.

High silicon Al-Si alloys with nanocrystalline structures have been produced by mechanical alloying process. Microstructural changes of the Al-Si alloys were investigated by scanning electron microscopy and the transmission electron microscopy. X-ray diffraction analysis was also made to characterize the lattice constant, crystallite size and misfit strain. It was found that the effective milling time by attrition milling was about 12hours for Al-70 wt%Si alloy system. The Al and Si crystallites were reduced to about 30 nm and 70 nm, respectively, by the mechanical alloying for more than 12hours. The misfit strains increased with milling time UD to 240 hours, and saturated to 5.73×10^(-3) for Al and Si crystallites, respectively.

이흥선,변박장,최순관,신원한,권귀향,이인수,이경석,김범태 순천향대학교 1994 논문집 Vol.17 No.4

The 1.06㎛ Neodymium-YAG Laser(800 micron hemisherical) is revealed a useful tool for percutaneous laser disc decompression(PLDD). Especially PLDD would be applied to the management of lumbar disc herniation with minimal intervention. Total irradiated energy to one level of disc space was bout 1000 to 2000 joules. We performed this method at 10 levels, in 7 cases of patients, consisting of 4 males and 3 females with an average age of 37.7 years. Five cases showed excellent and good results, were observed. In two cases, open surgery was required because of unsatisfactory results. The best results were obtained in the protrusion type of disc herniation. We have summarized some advantages of PLDD: a) safe and simple procedure in an outpatient setting, b) avoiding general anesthesia, late spinal instability, c) possibility of repetitive use.

External lyogels containing prostaglandin E₁ethyl ester(PGE₁-EE), a produrg of prostaglandin E₁(PGE₁) as a therapeutic agent for erectile dysfunction, were formulated to overcome the aqueous instability and enhance the percutaneous absorption. Lyogels of PGE₁-EE were prepared with ethanol (EtOH)/proplyene glycol (PG) cosolvent system as a vehicle, cineol as an enhancer, and hydroxypropylcellusose as a gelling agent. In vitro percutaneous absorption studies were performed to determine the rate of PGE₁ absorption through rat or hairless mouse skin. The permeability of PGE₁-EE lyogel with enhancer was 16-fold greater than that of lyogel without enhancer. Cosolvent produced 9-fold increase in percutaneous absorption. Pharmacodynamic effects of lyogels were evaluated in mature male cats in terms of intracavernosal pressure (ICP). Lyogles containing 0.01% of PGE₁-EE showed higher ICP compared to intraurethral preparation of PGE₁(1%) and enhancer-free control lyogel. The shelf-life (t_(10%) of lyogel at refrigerated condition (4℃) was calculated as 928 days, which is 4.2 times longer than that of control hydrogel. As a result, PGE₁-EE was formulated successfully to a lyogel system with a selective enhancer and cosolvent system for the topical delivery of PGE₁.
