베트남은 1991년 이래로 지속가능한 개발을 국가계획에 반영하여 온 최초의 몇 안 되는 실행국가이다. 2004년 4월에는 베트남의 수상이 베트남 아젠다 21의 지속가능성과 연계한 전략적 접근에 대한 결정을 문서화하고 있다. 아젠다 21의 제28장에서 언급된 바와 같이 지역 자치단체장은 지역 아젠다 21을 실행하기 위한 과정에 참여하고 있으며 이는 지역사회, 지역의 정책 및 프로그램이 국가계획과 연계되어야 하며 지역의 단체들은 이 부분에 준비 및 참여를 수행하였다. 본 논문은 이러한 국가 계획하에 아젠다 21을 수행한 2개의 지방자치단체에 대한 참여프로그램 분석을 수행한 연구이다. 랑손시의 대중위생관리 및 미칸마을의 녹색성장에 대한 참여프로그램을 분석하였다.

Recently, the social and environmental functions of nature river are important due to the increase of expectation for river restoration. So it should be considered the effect of vegetation affecting the conveyance capacity and hydraulic resistance. However, it has not yet proposed a objective standard and modeling method to estimate the effect of conveyance capacity according to vegetaion distribution in the watercourse such as water level or velocity. Therefore, this study simulates the variations of water level and velocity using 3-dimensional hydrodynamic model, EFDC, to consider a conveyance capacity in downstream of the Soyang Reservoir. The simulation results were validated using statistical index such as F-test and T-test. As results, the water level rises about 0.01 to 0.47m and velocity difference are about -0.95m/s to 0.23m/s.

In this study, a diagnostic wind model, CALMET and a micrometeorological numerical model, ENVI-MET were used to analyze the wind field in and out of the site designated for the industrial complex around Buron-myeon, Wonju, Gangwon-do. The results of modeling with CALMET showed that the air flow in industrial complex was little affected by the surrounding terrain. And the result of wind field analysis with ENVI-MET showed there are turbulent air flows such as cavity and wake around structures in the industrial complex, which can cause high-air pollution. Therefore, it is necessary to design the industrial complex considering the wind path according to wind directions.

River otter(Lutra lutra) are listed as endangered species and Natural monument in Korea, and this study examined the possibility of extinct of river otter in Hongchon river using with the application of Population Viability Analysis (PVA) technique. In Hongchon river areas population was estimated 9 individuals for the last 1999-2005 years and PVA analysis was done for the next 10 years using the average population of 9. Using the initial population the river otter was estimated 30% of extinct for the next 10 years. This estimation was quite low considering water pollution and construction of highways. Also PVA only used population size lacking in other life history information. Nonetheless river otter population can be in risk of extinction if the current construction of crossovers, cement bank are maintained. Long term information regarding life history needs essential.

In this study, the plausible grid size was estimated to increase for efficiency of reservoir management using 3 dimensional water quality model. To validate utilization of a real time water quality management tool, ELCOM-CAEDYM model was applied to Soyang reservoir in korea. 100m grid size can represent the real topography and take out exact analysis results. $400{\times}400m$ grid can be easily used to analysis because of data capacity. Consequently, the grid size of 200m or 300m was recommended to establish 3D model considering the required simulation time and the irrelevance between horizontal grid size and vertical distribution for temperature and turbidity analysis.

This study was conducted to investigate the sudden rise of fine particle concentration after the passage of typhoon USAGI and NARI in Busan. Nocturnal inversion layer was formed at atmospheric boundary layer and wind direction changed from southerly wind to northeasterly wind after USAGI passed through Busan. Fine particle concentration in Busan rapidly increased by subsidence of air pollutants released from sources and dust transported from in the vicinity of industrial regions. Wind direction changed from northeasterly wind to southeasterly wind, wind velocity increased and lower atmosphere became extremely unstable after NARI passed through Busan. $PM_{10}$ concentration of Busan increased sharply because of surface dust dispersed by strong wind. Fine particle concentration generally decreases by precipitation and wind after typhoon passes through. However, the concentration can also go up not only by subsidence and transportation in nocturnal inversion layer but also by surface dust which temporarily occurs by strong wind.

기후변화와 무분별한 개발 등으로 인해 생물다양성의 감소와 멸종 위험이 심각해짐에 따라 자연생태계에 대한 보전의 중요성이 높아지고 있다. 이러한 상황에서 본 연구는 자연자원과 생태계 변화 등에 대한 정보제공을 목적으로 한 평가기반의 자연생태 전망평가체계에 대한 국외 사례를 검토하였다. 결과로서 국외에서는 국내와 유사하게 다양한 조사기관에서 분류군별 조사를 수행하고 있으며 조사된 자료가 통합적으로 수집·관리되고 단기간내 지속적으로 제공되고 있다. 또한 기초조사 자료와 함께 평가기반의 예측·전망 정보를 제공함으로써 국가정책 및 환경영향평가 등에서의 활용도가 높은 것으로 조사되었다. 이를 바탕으로 국내 자연생태 조사 현황과 환경영향평가 등에서의 정보이용의 한계성을 분석하고 자연생태 정책수립 지원 등 정보로서의 자연생태 전망평가체계 작성 필요성에 대해 고찰하였다. 또한 제안된 자연생태 전망평가 등의 다양한 정보를 통해 국내 자연생태계 정책에 효과적으로 활용할 수 있는 정책방향을 제안하였다.

토양 환경은 그 유한성과 다양한 기능의 가치로 인해 중요한 자원으로 인식되고 있다. 따라서 많은 나라에서 토양의 질과 관련된 인자를 활용한 전략환경영향평가를 수행하고 있다. 하지만 우리나라는 아직까지도 오염도 위주의 제한된 인자만을 사용하고 있다. 본 연구에서는 개발기본계획에 대한 전략환경영향평가에서 토양의 복합적 특성을 고려할 수 있도록 개선하고 이를 보금자리주택 공급계획과 도시관리계획에 시범 적용하였다. 토양을 고려한 전략환경영향평가는 체크리스트 방법을 사용하여 상위계획과의 연계성, 대안 설정 분석, 입지의 타당성을 평가하였다. 평가 결과, 토양 유기물과 토양 침식 항목이 개발기본계획에서 가장 중요하게 고려해야 하는 인자로 도출되었다. 다만, 상기 두 인자에 대한 데이터베이스의 준비, 평가 비용의 증가 등을 예상할 수 있지만, 본 연구에서 개선한 전략환경영향평가 기법은 토양자원 보전에 기여할 수 있을 것으로 기대된다.

Aircraft noise model such as FAA Integrated Noise Model(INM) has recently been used for forecasting the impact of noise in a residential area near an airport and quantifying the effect of various options for noise mitigation. The noise modeling should be reliable and precise in order to ensure the quality of the results provided. In this study, the validation of the noise levels simulated by the INM against measurement data recorded continuously at multiple monitoring sites was discussed. As a result of validation, the quality of the input data used as a fixed point profiles for the INM was enhanced. The noise contour maps were designed as a way to evaluate the aircraft noise of the vicinity of the airfield. The results of this study indicate that the validation of aircraft noise model by the measurement data would be required for the accurate assessment of the aircraft noise levels.

In this study, the accurate water quality analysis in rivers, including the non-point source is performed. First of all, watershed model, SWAT(Soil and Water Assessment Tool) was applied to analyze the impact of the non-point source in study area. And then, water quality analysis integrating the point source and the non-point source is implemented using QUALKO model. For more exact simulation, it should be the calibration and verification of variables and parameters which are needed for simulation. In addition, the importance of considering the non-point source was confirmed in river water quality simulation. BOD, TN, TP were analysed, and the results shows that BOD, TN and TP concentration was increased to 16.8%, 8.2% and 25.8% respectively. The more accurate estimate will be carried if use of reliable measurements and watershed simulation be done in models linking process. The suggested technique will improve the accuracy of the water quality analysis. The methodologies presented in this study will contribute to basin-wide water quantity and quality management.
