This study examine operating system for eco-friendly container terminal and shows the usefulness of the Importance-performance analysis grid in evaluating container terminal operating technology. Importance-performance analysis enables management to evaluate and identify the major strengths and weaknesses of eco-friendly container terminal operating technology's key success factors. This study identified a list of 20 items from the eco-friendly container terminal literature reviews, and each item was rated using a 5-point Likert scale. Responses were obtained from 250 questionnaires. The importance-performance grid shows that 13 items fall into the "Keep up the good work" quadrant, 2 items fall into the "Concentrate here" quadrant, 2 items fall into the "Low priority" quadrant, and 3 items fall into the "Possible overkill" quadrant. The findings suggest that an eco-friendly container terminal operating technology is necessary to enhance eco-friendly operating system. The results are useful in identifying areas for strategic focus to help container terminal managers develop eco-friendly container terminal operating technology strategies.

This study analyzed the field applicability through the combination of environment-friendly grid-typed reinforcements and pre-mixed fiber with filler. The film of the grid-typed reinforcement is made by recycled PE resin. And, Ascon fiber is obtained the dispersion by pre-mixing of filler. To be able to recognize in advance the various circumstances that could arise in the construction of the road pavement layer, we conducted a basic field application test of the (Mock Up) pavement layer. As a result, it was found that the pavement with environment-friendly grid-typed reinforcement and dispersive fiber construction had improved strength, stress, and rutting resistance. It is consistent with the strength and stress results of the actual test of the mock up specimen. It is expected to perform an effective role in the safety as well as the use of environment-friendly fibers in actual construction.

In this study, we tried to analyze the suitability of factory development location in environmental aspects using the Green Development Suitability Map(GDSMap) which was created by GIS analysis about the optimal location of development projects. For this, it was evaluated a influence of various environmental factors that were caused by developments by setting the legislative, environmental and ecological assessment items. In addition, we made the GDSMap by reflecting the characteristics of region & development project overall. And, it were compared a location distribution on the GDSMap & NEZMap(National Environmental Zoning Map) to analyze a suitability of factory development location about the 39 factories located in study area. Results of analysis, the factory locations of about 23% of total development projects were confirmed that it was performed in development restrictions area on the NEZMap which was utilized current in selecting the location of development projects. And the factory locations of about 31% of total development projects could confirm that it was performed in development restrictions area on the GDSMap which was made in this study. Therefore, it was judged that it must be determined the development location by considering the characteristics of development projects & that region when selecting the location of various development projects.

The use of road cutters in the maintenance of obsolete underground facilities maintains polluting dust, cutting sludge, etc, polluting the air environment, soil, and water, causing civil complaints caused by noise, and consequently interrupting work. Therefore, it is time for eco-friendly pavement cutting technology for fugitive dust and cutting sludge emission management and noise management. This study was based on research by the development of eco-friendly pavement cutting technology in urban areas. In this study, the current state of existing road cutters is investigated and the patented technology analysis of road cutters is conducted to derive the design elements of eco-friendly pavement cutting technology.

최근 도시화에 따른 인구증가와 더불어 도로포장 등 불투수면적의 증가로 인하여 우기시 빗물 침투가 차단되어 도심의 지하수위가 저하되며 토양의 건토화, 열섬현상 등의 문제가 발생하게 되었다. 이러한 문제점에 착안하여 본 연구에서는 투수효과를 최대한 고려할 수 있는 고강도의 친환경 콘크리트 블록(에크스톤 바이오 블록; ECOSTONE-BIO BLOCK)을 개발하였으며 기존 콘크리트 블록의 자연적 빗물침투 억제의 문제점을 일부 개선하였다. 본 블록은 캡슐공법을 사용하여, 공극률은 높이면서(투수성 향상), 강도와 내구성이 유지됨은 물론 캡슐안에 황토성분을 첨가하여, 바이오적인 기능 및 재생골재를 이용한 친환경적 제품으로 투수성, 내구성, 기능성을 극대화 시켰다. 또한 제품표면은 천연 백색돌맹이, 흑색돌맹이의 배합으로 자연석재 느낌을 구현하였으며, 쇼트블라스트 및 커링 표면공정으로 미끄럼저항지수를 조절할 수 있어, 기존 콘크리트 보도블록에 비해 투수율, 내구성, 기능성, 안전성이 우수하여, 안전한 보행환경이 가능한 것으로 분석되었다. 마지막으로, 주변 환경과 잘 어울리도록 디자인된 바이오기능성 친환경 블록으로 도심지역 시공시 투수효과에 따른 지하수고갈방지 및 침수피해에 도움을 주리라 사료된다.

국내전력수요의 지속적인 성장과 더불어 전력산업의 대용량화, 고밀도화에 따른 친환경 고신뢰도의 전력계통 구성을 위하여 친환경 녹색기술의 초전도케이블이 실증시험을 통한 실계통 적용 사업이 이천변전소에서 정부지원으로 한전전력공사 주관으로 진행되고 있다. 그래서 향후 초전도 케이블이 실계통에 연계한 계통이 운용되는 것을 고려해야 하기 때문에 기존 전력기기와 협조하여 운영되기 위해서는 계통영향 분석이 필요하다. 특히 초전도케이블은 초전도성이라는 물리적인 특성 때문에 기존 계통해석과정과는 다른 계통 과도현상의 모델링이 필요하다. 따라서 본 논문에서는 초전도케이블의 실계통 적용을 위해서 이천변전소에 시범 적용된 22.9kV 50MVA 500m 초전도케이블 계통을 대상으로 열적특성을 분석하고 안정적인 대규모 전력전송을 위해서 초전도 케이블을 열적특성으로부터 보호하기 위한 열동계전기(Thermal Protection Relay)의 운영방법과 적용방안을 소개하고자 한다. 향후 대용량 초전도케이블의 실계통 적용 확대를 고려한 열동계전기의 운영방법과 적용방안도 제시하고자 한다.
