In this prolonged economic recession, the countries in Northeast Asia play a crucial role in the global market and the relationship between Korea and China gets more attention due to its significant achievement during the past 20 years after the establishment of diplomatic ties in 1992. In this regards, this study presents general overview of Korea-China Car Ferry Route and evaluates the efficiency level of each operating route using DEA model. Incheon-Yingkou, Incheon-Lianyungang, Pyeong Taek-Lianyungang are analyzed as efficent routes, while from the view point of passenger efficiency, 4 routes i.e, Incheon-Dalian, Incheon-Dandong, Pyeong Taek- Weihai, Gunsan-Shidao are also noted as efficient routes. Consequently, other inefficient routes can benchmark these efficient routes by increasing cargo volume and passengers.

In Korea, small-scale reclaimed areas have been suffering from many problems because of the lack of comprehensive developing strategy although considerable investments have been inputed by the public sector since 1970's. For 3 reclaimed sites in Chonnam Province choser as case study areas, the analysis, the second attempt of widely-spanned studies on areal conditions, concentrated on their farming and economic conditions. Its results were as follows ; 1. Although farming pattern has been transferred to the full4ime rice cropping type by the creation of reclaimed paddy field, farming size in the areas has not been increased more than that in existing agricultural areas. This means that agricultural planning should be included in the initial stage of reclamation projects, especially with reference to the substantial enlargement of farming size. 2. Block parcelling of severely fragmented holdings in new and old lands should be carried out, which can make farming activities efficient and farming route shortened. In large-scale reclaimed areas, new village planning could be considered in its central zone for efficent farming. 3. Because soil in the areas contains much more salt and water than that in other areas, new design methodology should be introduced for the efficient use of agricultural machines in reclaimed areas. 4. There are deep-seated economic problems in reclaimed area, which have been caused by very poor level and agriculturally dominated structure of household income. These problems should motivate farmers to give up positive action for qualitative and quantitative improvement in farming.

최근 환경적인 문제와 자원고갈 등으로 인해 재활용에 대한 관심이 커지고 있다. 특히 폐기물의 처리에 대한 문제가 커져가고 있는 상황에서 국내 폐기물량의 상당 부분을 차지하는 건설폐기물의 처리에 대한 다양한 접근이 필요하다. 건설폐기물 중 상당량을 차지하는 폐콘큰리트의 재활용에 대한 연구는 점차 늘어나고 있지만, 보다 경제적인 폐콘크리트처리 방법에 대한 연구는 미흡한 실정이다. 본 연구에서는 건설폐기물 중에서 가장 많이 차지하고 있는 폐콘크리트를 각각의 처리방법별로 경제성을 분석하고, 그 결과를 바탕으로 상황별 최선의 처리 방법 선택의 판단 근거를 제시 하였다. 이에 본 연구는 다양한 조건의 현장에서 향후 건설폐기물 재활용 방안 선택의 기초 자료로 활용될 수 있을 것이다.
