  • This study is to estimate differences, relationships and related factors of environmental risk perception and perceived benefit among residents and workers. A self-administered questionnaire survey using a structured instrument was carried out to residents and workers in industrial area during April, 2002. Total number of participants were 657 including 329 residents and 328 workers. Participants assessed environmental risk perception, self- assessed knowledge, trust in authorities and perceived benefit associated with 10 products manufactured in industrial area. There were difference in environmental risk perception, knowledge and trust in authorities and perceived benefit among residents and workers. Especially, trust in authorities and perceived benefit were statistically significant difference among residents and workers. Inverse relationships between environmental risk perception and perceived benefit have been observed for different products. In other words, the greater the perceived benefit, the lower the perceived risk, and vice versa. Factors mostly associated with participant's characteristics of environmental risk perception were age. marriage status (workers), education level (workers). There was statistically significant difference. Perceived benefit was statistically significant difference with sex, marriage status, residence duration, education level (workers). Related factors of environmental risk perception among residents and workers were age, trust in authorities. And factors affecting the perceived benefit were sex, age, education level (workers), and trust in authorities (workers). According to the results, people having high trust in the authorities perceived less risks than people having low in the authorities. To improve the communication of risk information, further study focus on assessment of experts, government and stakeholder in industrial area. Methodologies of this study can be used as the basis for investigating the structure of public perception of environmental products risks and benefit, designing a public information and risk communication program, and developing policy actions to improve acceptance.

  • The conflicts between environment protection and economic development are becoming increasingly important in environmental decision making of Nakdong River Basin. A science-based evaluation system is now needed to represent both the environmental values and the economic values with a common measure. EMERGY, spelled with an \"m\" evaluates both the work of river and that of human in generating products and services. The monetary cost-benefit analysis and the environmental accounting by EMERGY analysis were applied to determine whether there will have a net benefit in environmental decision making of Nakdong River Basin. Based on the results of the environmental accounting, all alternatives which related to environmental decision making of Nakdong River Basin show that more and more of EMERGY cost becomes needed than the a EMERGY benefit from getting water to drink in the lower basin. From these results, for selecting alternatives to manage water quantity and quality that is sustainable in the environmental use and economic development, environmental accounting concepts must be considered, and the economic structure of Nakdong River Basin should be changed from the present industrial structure to social-economic based on ecological-recycling concept for the sustainable use of Nakdong River.ong River.

  • The environmental problem come because the demage cost of environmental pollution is not properly reflected in market price. The government regulations for market is justified to solve the problem. The policy needs a close analysis of environmental, economical effect for the point of time, methods, rational decision making of the government regulations. Especially, we need to assume and analyze about social expenses by environmental pollution and policy execution. The cost-benefit analysis about environmental pollution is used to support decision making. The value of benefit about damage by environmental pollution or about improvement changes a monetary unit through the cost-benefit analysis. The working like this is said environmental material valuation or measuring valuation. This work is studied about looking for proper analysis model to apply our environmental materials.

  • Since the Renewable Portfolio Standard (RPS) would be started in 2012, the use of renewable energy should be 11% of total energy use including bio-fuel in 2030. The economic efficiency for renewable energy in B power plant was considered with the bio-diesel, wind power and solar power. The Net Present Value (NPV) and Benefit/Cost Ratio(BC) were used for the economic efficiency with the cost and benefit analysis. In case of bio-diesel, the cost resulted from the fuel conversion and the benefit would be created with trade and environmental improvement. With regard to wind power and solar power, the construction cost would be required and benefit factors would be same as the bio-diesel. The wind power was the best of economic efficiency of renewable energy as the results of NPV and BC ratio. Whereas, the market of wind power was very popular and the techniques of wind power has been developing rapidly.

  • 서울시는 '건강한 물순환 도시' 조성을 비전으로 선포하고 도시 물환경 악화에 따른 문제를 해결하기 위한 노력을 기울이고 있다. 이를 위해 서울시는 빗물의 침투 및 저류 기능 등을 이용하는 저영향개발(LID) 시설의 설치를 확산시키기 위한 정책 및 제도 개선을 추진하고 있다. 이러한 저영향개발 시설은 공공이 선도하는 물순환 도시 조성과 이를 위한 빗물의 표면 유출 억제와 물이용 효율화를 목적으로 하고 있다. 또 악화된 물순환과 물환경을 회복하기 위해 다양한 저영향개발 시설이 설치 및 운영되고 있다. 그러나 이에 대한 체계적인 경제성 평가를 위한 편익 분석 방안은 미흡한 실정이다. 따라서 본 연구에서는 저영향개발 시설의 경제적 환경적 사회적 편익을 다각적으로 분석하기 위해 저영향개발 시설별로 물 에너지 대기질 개선 기후변화 대응의 4개 카테고리별로 편익 분석항목을 선정하였다. 이러한 카테고리별 분류에 따른 직간접인 편익효과의 정량화 및 가치 평가 결과, 각 시설별로 연간 1,191원의 단위면적 당 편익이 발생하는 것으로 산정되었다. 분석 항목별 편익 분포 특성은 시설의 특성에 따라 다양한 것으로 나타났다(물: 30~90%, 에너지: 4~44%, 대기질 개선: <1~2%, 기후변화 대응: 5~22%). TBL 분석 결과, 시설별로 경제적 편익의 비중이 가장 큰 것으로 나타났으며(75~90%), 환경적 편익(<1~2%) 및 사회적 편익(9~24%)이 산정되었다. 향후, 현재의 개별 저영향개발 시설에 대한 편익 분석 방안을 기반으로 단지 및 지구단위의 물순환 연계 시스템이 적용될 경우, 도시 열섬 현상 및 홍수 재해 예방 등 저영향개발 시설 운영의 편익에 대한 시너지 효과 등을 평가할 수 있을 것으로 기대된다.

  • 본 연구에서는 에너지절감 제품을 대상으로 친환경성이 소비자의 제품에 대한 구매의도에 미치는 영향을 분석하였다. 이를 통해 본 연구에서는 에너지절감 제품의 경제성, 편리성, 친환경성 등이 구매의도에 유의한 정(+)의 영향을 나타내는 것을 확인하였다. 또한, 이들 구매영향 요인들 중 경제성과 친환경성의 효과는 소비자의 환경의식 수준에 따라 달라져서, 환경의식이 높은 소비자는 경제성에 둔감하게 반응하여 경제성이 낮더라도 친환경 제품에 대한 구매의도가 환경의식이 낮은 소비자에 비해 크게 줄지 않으며, 친환경성에는 민감하게 반응하여 친환경성의 높아지면 친환경 제품에 대한 구매의도가 환경의식이 낮은 소비자에 비해 크게 높아지는 것으로 나타났다. 본 연구의 결과에 따르면 친환경제품에 대한 마케팅전략을 수립함에 있어 소비자의 환경의식을 고려하여 환경의식이 낮은 집단에서는 해당 제품의 경제성을 높여 소비자의 비용을 절감 시키는 방안이 요구되고, 환경의식이 높은 집단에서는 해당 제품의 친환경성을 강조하는 것이 효과적일 수 있을 것이다.

  • It is necessary to study and develop guidelines for providing comfort and health indoor air quality for office workers since air-tight envelope system of current office building may cause poor indoor air quality. The purpose of this study is to propose guideline for volatile organic compounds in office base on the field study, human health risk assessment and cost-benefit analysis. The field study was conducted to survey the concentrations of volatile organic compounds in indoor air of 69 offices from June to September, 2005 in Seoul and Gyeonggi-do. The rate of excess to guideline of volatile organic compounds in indoor air of new apartment on the Ministry of Environment in Korea(MOE) was surveyed 37.6% for benzene, 6.8% for toluene, and 1.5% for ethylbenzene. As the result of human health risk assessment, mean cancer risk did not exceed 10-6 which is guideline of US.EPA. Also, total hazard index did not exceed 1 which is guideline of US.EPA. Through the cost-benefit analysis of angle on the social-economics to verify the necessary to establish the standards of volatile organic compounds for improvement and development of indoor air quality in office, the present value of benefit was higher than the present value of cost. With the above considerations in mind, it is suggested that the field study for indoor air quality in offices should be expanded and human health risk assessment and cost-benefit analysis be performed th offer scientific data for decision-making of policy for improvement and management of indoor air quality in office.
