지역경제의 생태학적 평가에 관한 연구 : 낙동강 유역을 중심으로 The case of Nakdong River region, Korea
윤갑식,김홍배,최세호 漢陽大學校 環境工學硏究所 1998 環境科學論文集 Vol.19 No.-
본 연구에서는 수질오염이 산업폐수, 가계하수 그리고 토지유출수의 3가지 요소에 의해서 발생된다는 가정을 바탕으로 환경수준과 경제활동 사이에 존재하는 상반관계를 낙동강유역을 대상으로 분석하였다. 분석에는 다지역 투입산출모형이 이용되는데 이때의 다지역 투입산출표는 행정구역이 아닌 유역권을 기준으로 작성되었고 이를 바탕으로 목표년도(2010)의 낙동강 유역 수질수준을 예측하였다. 또한 수질을 개선하기 위해 두가지 정책 즉, 자체처리시설을 증설하는 정책과 종말처리장을 증설하는 정책을 제시하고 이것을 정책에 소요되는 비용과 정책효과 측면에서 평가하여 지역별 가장 효율적인 정책을 제시하였다. 마지막으로 GRDP에서 수질오염에 의해 발생하는 환경비용을 고려한 ERDP(환경적으로 조정된 지역내 순생산)를 제시하였다. This paper analyzes the trade-off relationship between environmental quality and economic activity, specifically focusing on water pollution of Nakdong-river region, Korea. The analysis begins with the assumption that water is contaminated by three pollutive sources, production sector, household sector and land surface water. Three-region input-output table is constructed based on the Catch basin area not administrative area for analysis. Water polluting level of Nakdong river region in the year 2010 is forecasted taking into account the pollutive sources. Also, two types of environmental policies are presented and assessed in terms of pollution abatement costs and effects. Finally, the interest in this paper stems from recent advances in so-call EDP(environmentally adjusted net domestic product) which reflects environmental costs in GDP. The paper attempts to calculate ERDP(environmentally adjusted net regional domestic product) by incorporating EDP into regional level with the assumption that environmental costs are represented by water pollution abatement costs.

We previously reported that the exogenous administration of cumambrin A, a sesquiterpene lactone from the dried flowers of Chrysanthemum boreale Makino has a pharmacological effect on normalization of blood pressure in the spontaneously hypertensive rats (SHR). In the present study, we further investigated the effect of cumambrin A on the relaxation of phenylephrine-induced precontracted rat aortic artery rings. The potency of cumambrin A was then compared to verapamil, a well known Ca^(2+)-channel blocker. The results demonstrate that the isolated rat aortic arteries are relaxed to basal tension at a concentration of 5X10^(-5)M cumambrin A treatment. The results also show that the phenylephrine-induced contraction is inhibited by a pretreatment of cumambrin A. Co-treatment of cumambrin A and verapamil showed a strong synergetic effect on the relaxation of rat aortic artery rings. Thus, these data demonstrate that cumambrin A is a potent relaxant of rat aortic smooth muscle and suggest that cumambrin A modulates intracellular or extracellular Ca^(2+) mobilization.

Studies with diabetic mammalian systems showed that chiro-inositol administration decreased blood glucose levels. We investigated which foodstuffs contain large amounts of chiro-inositol by surveying vegetables, edible plants and other staples in an effort to explore the nutritional or therapeutic supplements of chiro-inositol for diabetic patients. In the course of our investigation, we found that soybean and soybean derivatives have high chiro-inositol levels (upto 20 mg/g). The purified chiro-inositol from the soybean was then tested for reducing hyperglycemia by administrating the chiro-inositol in streptozotocin-treated diabetic rats. The results showed that the intragastric administration of 50 mg chiro-inositol/kg BW lowered hyperglycemia by 40% and that the effect was sustained for approximately 12 hr.

Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

객체 지향 데이타 모델을 지원하는 데이타베이스 시스템은 기존의 데이타베이스의 단점을 보완하며, 다양하고 복잡한 실세계의 정보를 처리할 수 있다. 객체 지향 데이타베이스 시스템은 사용자의 접근을 위해 질의 및 객체 관리 인터페이스를 필요로 한다. 본 논문에서는 사용자를 위한 질의 인터페이스와 질의 계획을 수행하기 위한 객체 관리 인터페이스를 설계함으로써 질의 목적을 달성토록 하였다. 설계된 객체 관리 인터페이스는 응용을 위해 "C"언어 함수로 구성하였고, 성능 항상을 위한 확장성을 제공할 수 있도록 설계 하였다. The database system that supports object oriented data model can complements conventional DBMS's drawbacks and processes complex and intensive applications. In object oriented database system, the access and management of all objects are manipulated by object manager. Therefore, a query interface as well as an Object Manager Interface(OMI) is required for interfacing between a user and an object store. In this paper, we propose the query interface which can support object oriented paradigm and design rules of OMI, and implement OMI based on the rules. The OMI have been implemented by using C language on UNIX OS machine.

For the optimal design of plasma facing components of a fusion reactor, the thorough understanding of thermal behavior of high heat flux components are required. The purpose of this research is to investigate the characteristics of heat flow and thermal stress in divertors which are exposed to high heat load varying with time and space. Numerical simulations of heat flow and thermal stress for three types of divertor are performed using finite volume method and finite element method. Respectively, commercial FLUENT code are used in the heat flow simulation, and maximum surface temperature, temperature distribution and cooling rate are calculated. Commercial ABAQUS code are used for calculating temperature distribution, thermal stress, strain and displacement. Through this computer simulation, design data for cooling system and structural are provided.

Naphthalene sublimation technique is employed to investigate the heat transfer enhancement of fin-tube heat exchangers using vortex generators. Experiments are performed for the fin-circular tube heat exchanger with and without vortex generators, and fin-flat tube heat exchanger with and without vortex generators. Local and spanwise averaged heat transfer coefficients are measured on the surface of fin, and compared with those obtained without vortex generator. Average heat transfer coefficients of fin-flat tube heat exchanger are much lower than those of fin-circular tube heater exchanger. On the other hand, fin-flat tube heat exchanger with vortex generators has a little higher heat transfer value than fin-circular tube with vortex generators. Friction loss for four types of heat exchanger are also measured and compared.
