한강은 서울 지역을 관통하고 있다는 점에서 수도권의 수자원 이용과 폐수 수용체로서의 한강의 역할이 실로 막대하다. 이런 맥락에서 한강에서의 수질오염문제는 주요한 사회경제적 문제 중의 하나로 부각되고 있다. 한강 수질 악화를 방지하기 위한 관리 방안이 이미 시행중에 있으나 여전히 한강 수질 오염은 문제로 남아 있는 실정이다. 이를 감안하여 보다 나은 관리책에 대한 요구에 부응하기 위하여 본 논문은 기존의 수질기준을 최소비용으로 달성하는 비용 효과적인 방식을 시스템 최적화 분석 기법에 접목하는 모델을 구축하고 있다. 이 모델은 우리 나라에 두드러진 수문학적 특징, 즉 자정능력상의 계절적 차이가 지역적 특성과 오염 처리 기술상의 다양함, 그리고 기존의 법적 제도적 특정들과 어떻게 연결되어 얼마나 처리 비용상의 절약을 유도해 낼 수 있는지에 관한 정책정보를 제공해 줄 수 있게 고안되었다. 연구의 결과치에 의하면, 표적 지천상의 지역적 안배와 처리 공정상의 기술-비용적 차이를 고려하고 비갈수기에 처리시설을 신축적으로 운영할 경우 한강 수계에서 BOD 부하량 삭감비용은 상당한 정도( 예로, 1992년 물가수준에서 매일 3,000만 원 이상) 절감 가능한 것으로 나타나고 있다.

2011년 후쿠시마 원자력발전소 사고 이후, 발전원의 위험사고비용 및 환경피해비용에 대한 관심이 대두되고 있다. 전력은 생산과정 뿐만 아니라 발전소 건설, 발전소 운영, 송 배전을 통한 전력 공급, 폐기물처리 등의 각 과정에서 다양한 환경비용을 야기하고 있다. 따라서 발전원의 환경영향을 수용자적 입장에서의 평가할 필요가 있다. 본 연구에서는 컨조인트 분석법의 일종인 선택실험법을 적용하여 발전에 따른 환경영향 속성들에 대해 평가한 후, 발전원별로 상이한 속성 값에 속 성별 추정치를 반영하여 발전원별 환경비용을 수용자적 입장에서 추정하였다. 발전원부문이 환경에 미치는 영향에 대한 속성을 온실가스 배출, 건강피해, 지역피해, 온배수 배출로 선정하였고, 제시금액은 비교 대상 발전원들의 전력거래 단가 및 가구당 지출하는 월평균 전기요금수준을 기준으로하여 35,000원에서 75,000원까지의 총 다섯 가지 속성수준으로 구분하였다. 다항로짓모형을 적용하여 발전원별 각 환경영향에 대한 속성별 한계지불의사액 추정하고, 발전원간의 환경비용을 산정하였다. kWh 당 수력발전(0원/kWh) 대비 타 발전원의 추가 환경비용은 26원/kWh­832원/Wh로 환경적 영향 측면에서 국민수용성이 가장 높게 나타났다.

It is very difficult to accurately calculate efficiency of each accessory device constituting the pump system and pump efficiency by the Conventional efficiency measurement method only. Therefore, this study introduced the lastest Thermodynamic pump efficiency measurement method in the district heating pump system for the first time in Korea. As a result, data uncertainty was high by the Conventional method, but the pump and Hydraulic Coupling efficiency values applied the Thermodynamic and Conventional method parallel measurement data were able to derive meaningful results that verified the reliability and adequancy of the pump performance measurement method by performing complementary roles. In additon, as a result of applying the Thermodynamic method to the distirct heating pump system, despite the high temperature environment of up to 120 ℃, it was possible to verify the reliability of the Thermodynamic method, such as high stable data mesurement, and durability of the measurement equipment.

Local opposition and protest constitute single greatest hurdle to the siting of locally unwanted land uses(LULUs), especially siting of high-level radioactive disposal not only throughout Korea but also throughout the industrialized world. It can be attributed mainly to the NIMBYism, equity problem, and lack of participation. These problems are arisen from rational planning process which emphasizes instrumental rationality. But planning is a value-laden political activity, in which substantive rationality is central. To achieve this goals, we need a sound planning process for siting LULUs, which should improve the ability of citizens to influence the decisions that affects them. By a sound planning process, we mean one that is open to citizen input and contains accurate and complete information. In other word, the public is also part of the goal setting process and, as the information and analyses developed by the planners are evaluated by the public, strategies for solutions can be developed through consensus-building. This method is called as a co-operative siting process, and must be structured in order to arrive at publicly acceptable decisions. The followings are decided by consensus-building method. 1. Negotiation will be held? 2. What is the benefits and risks of negotiation? 3. What are solutions when collisions between national interests and local ones come into? 4. What are the agendas? 5. What is the community' role in site selection? 6. Are there incentives to negotiation. 7. Who are the parties to the negotiation? 8. Who will represent the community? 9. What groundwork of negotiation is set up? 10. How do we assure that the community access to information and expert? 11. What happens if negotiation is failed? 12. Is it necessary to trust each other in negotiations? 13. Is a mediator needed in negotiations?

The purpose of this study was to explore natural groupings among adults based on gender role conflict, ambivalent sexism and aggression, and find differences in their acceptance of rape myths. 372 male and female adults in the Daegu and Gyeongsang province were surveyed and 350 were analyzed on their gender role conflict, ambivalent sexism, aggression and acceptance of rape myths. The cluster analysis divided participants into sub-groups such as 'unaggressive but conflicted about gender stereotypes', 'receptive to adaptive gender notions ' and 'compliant to aggressive gender stereotypes'. The sub-groups had differing levels of gender, age and education. There were differences in acceptance of rape myths among these groups, Post-hoc testing showed that the 'compliant to aggressive gender stereotype' subgroup showed the highest level of acceptance of rape myths, following by 'unaggressive but with gender stereotype conflicts' and 'receptive of adaptive gender notions'. Finally, needs for assessing individual characteristics according to their subgroup types and developing psychoeducational programs focused on the subgroup characteristics were addressed. Then, recommendations for future study were discussed.

This study aims to reveal how a port affects the living conditions of its neighborhood area with a case study of Pusan New Port and to suggest several implications to port policy. PLS-SEM reflective measurement model satisfies the criteria on reliability and validity, and also structural model meets the criteria in terms of R2, path coefficients' significance and predictive relevance(Q2). The results of PLS-SEM support the hypotheses of this study: The expansion of Pusan New Port contributes to the improvement of living conditions of Gangseo-gu(nearby area) through its significant and sequential effects on the employment and population increase of Gangseo-gu. The originality of this study can be found in enunciating that a port plays a role as a driving force of the betterment of living conditions of its nearby Gu-level area. In terms of policy, central and local governments and port related companies should cooperate with each other to reinforce the acceptability of port policy through the improvement of the living conditions of port neighborhood area. To evaluate comprehensively the influence of a port on its neighborhood area, a further study needs to identify how a port affects the quality of life of the area or what kinds of socio-economic effects a port has on the area.

Using survey data of selected 1,349 individuals nationwide in Korea, we measure the influencing factors for the acceptance of nuclear power and estimates the probability of acceptance under several scenarios with different percentages of monetary compensation. Results of panel probit demonstrate that nuclear risk aversion tendency was found to be higher in case of female, younger age, past experience of extreme event such as an earthquake. However, the residents' residency nearby the nuclear power plant was not related to the risk-aversion tendency. In addition, we found that the nuclear acceptance is improved when the monetary compensation rate is increased. Although the policy demand intended to reduce GHG emissions in South Korea, the expansion of nuclear power is not be easy due to the occurrence of recent strong earthquakes because the risk attitude of an individual is influenced by subjective assessments formed through direct and indirect experiences of natural disasters such as an earthquake. Our results suggest that the opposition to construction of nuclear power plant is expected to be further intensified especially when combined with the experiences of threatening earthquakes. As a result, the debate and policy conflicts of nuclear power plants will consistently continue and large social costs are apparent for the acceptance of nuclear power plant.
