  • 본 연구에서는 의사결정자의 대립관계가 있는 항만개발 문제에 대한 우선순위 평가와 보상관계를 분석하였다. 이를 위해 먼저 항만개발에 대한 관련문헌을 분석하여 평가요소를 추출하였고, FSM법을 이용하여 평가요소를 구조화하고, 구조화 분석을 통해 평가항목을 선정하였다. 두 번째, 항만개발 평가 주체를 지역주민, 이용자, 지자체로 선정하고 AHP법을 이용하여 종합 평가치를 산출하였다. 세 번째 JMPR법을 이용하여 평가주체간 제휴를 구성하였을때 종합 평가결과와 대체안 선정에 따른 불만량을 최소로 하여 평가하는 방법을 제시하였다. 또한 대체안 선정에 따른 보상문제를 정량화하고 보상관계를 분석하였다. 그 결과 대상 항만중 부산항 개발이 가장 우선되어야 하며, 항만이용자는 환경에 대한 인식의 개선과, 지자체에서는 환경 친화적인 항만개발을 위한 환경 인센티브 정책을 추진해야 할 것이다.

  • EMEP/EEA Emission Inventory Guidebook에 의하면 자동차 주행에 따른 총 대기오염물질 배출량을 Hot Start와 Cold Start로 구분해 산출하도록 하고 있다. 본 연구에서는 이러한 자동차 주행주기 특성을 감안하여 교통사업의 타당성 분석 시환경비용절감 편익의 현실적인 산정방안에 대해 검토하였다. 이를 위해 교통수요 분석모형(EMME/3)을 이용하여 분석영향권내 모든 링크단위의 교통량과 통행속도 자료를 활용하는 Tier 3 방식으로 환경오염 물질을 선출하였다. 본 연구에서 제안된 방법론의 적용성 검토를 위해 현재 계획중인 철도 투자평가사업에 적용하였으며, 적용결과 환경부문의 편익이 기존 대비 약 30% 정도 증가하는 것으로 나타났다. 향후 본 연구에서 제안한 방법론이 투자평가과정에서 적용된다면 철도와 같은 친환경 교통수단의 투자활성화에 기여할 것으로 기대한다.

  • Due to rapid climate changing and the need for energy conservation, environment friendly initiatives have emerged, and regulations to support establishment of green structures in construction have been legislated and enacted. In this study, the supporting of green build method act for rapid climate change and energy conservation. Using green build method, protecting surrounding ecosystem and developing green building continuously, I suggest alternative for protection of the environment. Identifies Envelope Design Elements among various construction Green Building Design Guidelines. Green buildings that we extract the Green Building envelope design from Design Guideline, select the object building through the green buildings examples of public institution relocation projects. Since then analyzes the planned schematic design and Green Envelope Design Elements and Green Building Certification(G-SEED). So, that future directions for planning correlation of Green Building and Design Guidelines about Green Design Elements Can be presented.

  • A safety assessment code, called SAGE (Safety Assessment Groundwater Evaluation), has been developed to describe post-closure radionuclide releases and potential radiological doses for low- and intermediate-level radioactive waste (LILW) disposal in an engineered vault facility in Korea. The conceptual model implemented in the code is focused on the release of radionuclide from a gradually degrading engineered barrier system to an underlying unsaturated zone, thence to a saturated groundwater zone. The radionuclide transport equations are solved by spatially discretizing the disposal system into a series of compartments. Mass transfer between compartments is by diffusion/dispersion and advection. In all compartments, radionuclides ate decayed either as a single-member chain or as multi-member chains. The biosphere is represented as a set of steady-state, radionuclide-specific pathway dose conversion factors that are multiplied by the appropriate release rate from the far field for each pathway. The code has the capability to treat input parameters either deterministically or probabilistically. Parameter input is achieved through a user-friendly Graphical User Interface. An application is presented, which is compared against safety assessment results from the other computer codes, to benchmark the reliability of system-level conceptual modeling of the code.

  • The objective of this study is to analyze the types and current status of development projects that underwent environment assessment in recent three years and provide basic data to encourage environment-friendly development projects in the future. This study was conducted by analyzing the pre-environment review reports and environment impact statements of development projects that took place in Gyeonggi province. Key findings are as follows. First, a total of 2,465 development projects spanning $173km^2$ were undertaken in Gyeonggi province in recent three years. This is equivalent to three times of the area of Anyang city. Second, types of development projects were in the order of factories and industrial parks, road construction, town (housing estates) development, sports facilities and waste treatment facilities. Public projects accounted for about 30%, while private investment projects represented 70%, indicating that private sector projects were as twice as high. The findings of this study show that the development density of Gyeonggi-do should be examined as a whole in order to develop a comprehensive, long-term plan and harmonize conservation and development systematically in Gyeonggi-do in a holistic perspective.

  • Nepal is one of the least urbanized countries in the world where more than 80% of the total population live in rural areas. In recent years, the rate of urbanization became rampant which ultimately accelerated immense pressure on municipal services, especially on managing the ever increasing amount of wastes. Due to lack of technology, infrastructure and financial capacity management of increasing amount of solid waste has become a major challenge in municipalities of Nepal. The indiscriminate dumping of solid wastes already affected the urban environment by creating a serious occupational health and environmental hazard to the vicinity of the dumping sites. However, there is great possibility of recovering methane from the landfill sites since the typical Nepalese municipal solid waste contains more than 65% of organic wastes. Despite having enormous potential of generating electricity from hydropower, Nepal is facing acute shortage of energy. Therefore, comprehensive scientific research and development is necessary for making solid waste to environmentally friendly by converting waste to the energy.

  • Due to sustainable development, international environmental regulations have been reinforced continuously. Especially, Kyoto protocol related to energy consumption affects to national production system seriously. Even if railroad is the most environmental- friendly transportation, it is necessary to improve its environment. Life cycle assessment (LCA) is a representative tool to evaluate the environment impacts of a product. In the EU's railroad companies, the recycling efficiency and the waste emissions of rolling stocks have improved considering their environment impacts with LCA from a design step. Also, the LCA system of Korean electric motor units has been developed to build an environmentally sound railroad as one of national transportation core technology R&D projects. Therefore, the introduction of LCA will be required to decrease environmental impacts released from rolling stocks in the future.

  • The purpose of this study is to suggest configuration methods of sensor according to user's behaviors in the ubiquitous house. Recently, with appearing the concept of 'Ubiquitous', the applications of ubiquitous technologies on the our environment adopt a new paradigm. This new paradigm leads to the possibility of creating more intellectual dwelling environment according to user's behaviors. This paper suggests to change our dwelling by considering both engineering technology and considering the character of dwelling, because the house should provide causes humans with comfortability. Therefore, we need to understand user's behaviors in the dwelling, towards user friendly environment.
