심문보 한국환경정책학회 2001 環境政策 Vol.9 No.1
The objective of this research was to lay out a scheme to enhance an efficiency and a beneficial cost effect on those planned and existing livestock waste facilities through making alternative ideas after grasping those problems related with facility operation and management carried out by individual livestock farmhouse and public treatment facilities in a local government. The research was focused on such livestock farmhouses as to produce the largest waste loads among those located in Chungnam province. The literature review was conducted to catch hold of the waste productions and present treatment conditions based on the data furnished by the live stock·related departments. Moreover, fined investigations into actual conditions were carried out to seize the problems related with maintenance and management of livestock waste treatment facilities. Since the optimum breeding heads are about two hundreds, the appropriate treatment facilities may minimize the maintenance/management costs. Besides, it is necessary to set up such facilities with low maintenance/management costs, easy operation, and no additional process. In terms of the economy of scale, the supporting funds should be concentrated on such livestock farmhouses with 2000 heads In order to enhance price competitiveness.

In an attempt to solve multiobjective optimization problems, many traditional methods scalarize the objective vector into a single objective. In those cases, the obtained solution is highly sensitive to the weight vector used in the scalarization process and demands the user to have knowledge about the underlying problem. Moreover, in solving multiobjective problems, designers may be interested in a set of Pareto-optimal points, instead of a single point. In this paper, pareto-based Continuous Evolutionary Algorithms for Multiobjective Optimization problems having continuous search space are introduced. This algorithm is based on Continuous Evolutionary Algorithms to solve single objective optimization problems with a continuous function and continuous search space efficiently. For multiobjective optimization, a progressive reproduction operator and a niche-formation method fur fitness sharing and a storing process for elitism are implemented in the algorithm. The operator and the niche formulation allow the solution set to be distributed widely over the Pareto-optimal tradeoff surface. Finally, the validity of this method has been demonstrated through a numerical example.

This study covered the area of Tapjeong reservoir located in Nonsan city to establish the efficient management and improvement of water quality. Based on the water quality examination, it was found that the current COD and chlorophyll-a concentration of the reservoir average about 3.2mg/L, 8.4mg/m3, respectively indicating that the water contamination is becoming worse. The watershed divided into seven areas based on the seven streams among which Nonsan area was found to discharge 80% of pollutant loads into the reservoir. The model predicted that the proper buildup of wastewater treatment facilities in Nonsan and Yongdang areas can significantly improve the water quality. The findings suggest the following water quality management alternatives, 1) construction of wastewater treatment facilities to reduce pollutant loads, 2) preparation of pollutant resistant plants living in contaminated water around the streams, 3) creation of ecological park and wetlands, 4) maintenance of restricted area for fishing in the reservoir, and so forth.
수도권 지역 도시민의 귀촌지역 결정과 지방자치단체의 귀촌지원 정책의 영향요인 분석 - 태안군의 사례를 중심으로 -

본 논문은 수도권 지역의 귀촌 희망자들이 성별, 연령, 직업, 소득, 지역에 따라서 귀촌지역 결정과 귀촌정보 취득 및 자치단체의 귀촌지원 정책들에 대하여 집단간에 어떠한 차이를 보이고 있으며. 지방자치단체의 귀촌지원정책에 미치는 영향요인들은 무엇인지를 분석하는데 있다. 이를 위해 수도권 지역 도시민 171명을 대상으로 설문조사를 실시하여 통계분석을 실시하였다. 분석결과, 수도권지역 도시민들이 귀촌지를 선택하는 이유는 경제적인 것 보다는 환경적인 것과 건강한 삶과 관련이 있었다. 또한 귀촌인들이 주로 귀농 귀촌 박람회와 주변의 지인을 통해 귀촌정보를 얻는 것에 상대적으로 높은 만족감을 갖고 있었다. 아울러 자치단체의 귀촌지원 정책들에 대하여 귀촌 희망자들은 지역주민과의 친밀감 조성과 건축 인허가 등 행정절차 안내 등이 매우 중요하다고 판단하고 있다. In this paper, we are trying to find out that there is making a difference between groups of returnees in the metropolitan area, regarding the decision of returning their hometown. We investigate what kind of factors make them reveal the preferences as to acquiring information on hometown and supporting policies for returning to their hometown, depending on gender, age, occupation, income and region. The purpose of this study is to analyze what factors affect local governments' support policies for returning their homes. To this end, a survey was conducted on 171 urban residents in the metropolitan area. The analysis showed that urban residents in metropolitan areas chose back-to-village home; because, they were more concerned with the environmental consideration and healthy lives rather than economic ones. In addition, the villagers had a relatively high level of satisfaction in obtaining the village information through the villagers' exhibition fairs and acquaintances. As the support policies of local governments are concerned, they believe that the guidance of the administrative procedures such as building intimacy with local residents and building permits are important.
