  • This study aims to present reference data necessary for developing evaluation indicators to analyze the actual resilience of purchased land by investigating the factors that affect the restoration of the purchased land in the riparian zone and quantitatively calculating its importance. The main results are as follows. Firstly, this study identified 34 potential resilience factors through a literature review encompassing domestic and overseas studies and derived seven ecological responsiveness factors, six physical responsiveness factors, and four managerial responsiveness factors through the Delphi survey. Secondly, reliability analysis and Analytic Hierarchy Process (AHP) analysis derived the following important factors: structural stability of the vegetation restored in the purchased land, species diversity of wildlife, structural stability of wildlife, the size of restored wetland after purchase, number of plant species, and the land cover status adjacent to the purchased land. The study results are expected to be helpful information for ecological restoration and management plans reflecting reinforcing factors for resilience at each stage of land purchase, restoration, and management.

  • After the Cold War, international terrorism and related issues have been the most urgent problems. However, Korea hasn't recognized this seriousness due to relatively slight damage. Yet the interest about the international maritime terrorism and related issues is increasing as the maritime terrorism issues emerged. This is because Korea is located next to three oceans and majority of international trades depend largely on international maritime transportation due to its scarce natural resources. Therefore this study has the purpose that it reviews the advanced researches and documents, analyzes the priority about response system against international maritime terrorism, suggests the practical solutions. For these purposes, it conducted Delphi technique to international maritime terrorism experts with response system factors selected among the advanced researches and documents. As the result of analysis, this study figured out that legal and institutional countermeasures are needed as international measures, strategic countermeasures are needed as domestic measures to set up the response system against international maritime terrorism. Synthetically, for the efficient and practical counteract against international maritime terrorism, the response institute against international maritime terrorism and the awareness of relevant experts are preferentially necessary.

  • This study was conducted for the purpose of the basic direction for the new regulations and categories of Ruralism changing in the new era. To this end, the results of Delphi analysis and AHP analysis by dividing it into the definition, criteria, scope and component items of Ruralism based on systematic literature review are as follows. First, through studies representing most rural areas, it was found that Ruralism was the most problematic keyword and most of the studies did not cover it as they were studying various ranges of rural areas. Second, the Delphi survey was able to derive keywords that can be used as evidence for item classification and clear concept establishment for the regulation and category setting of Ruralism. Third, through the hierarchical decision-making method, it was found that landscape factors are the most important thing in forming Ruralism as well as deriving priorities that can be a baseline for each item. This study is meaningful in providing a minimum baseline as basic data for establishing the concept of Ruralism, and it is believed that future-oriented Ruralism can be established if reviews are added from various perspectives to overcome limitations dependent on expert groups.

  • To increase port productivity and efficiency and also to avoid disadvantages of public port management, a port authority system h1s been introduced worldwide. The Korea Port Authority Act was enacted in 2003 and Incheon Port Authority was established in July 2005. The objective of this paper is to develop a strategy of Incheon Port Authority using SWOT/AHP method Research findings show that possibilities of business expansion and growth as well as geographical advantages of Incheon Port are identified as its strength The opportunities of Incheon Port Authority are continuous increase of cargo handling volumes in the Yellow sea rim and expansion of Free Trade Zone. A government two-port policy and growing its dependence on China and rapid growth of more competitors in domestic and overseas are considered to be threat. Its weaknesses include superannuated Incheon port facilities and port hinterland shortages. Based on SWOT analysis combined with AHP method this paper suggests S/O strategy, W/O strategy, S/T strategy, and W/T strategy as a strategic development plan of Incheon Port Authority.

  • The economical efficiency and easy ship building have enabled to spread FRP ships in the shipbuilding field. As waste FRP ships have been thrown away at a river or within a harbour, this matter has become issues. For the improvement of this matter, the melting technique and system of waste FRP ships was developed. But, Decision making was required for a location plan of the melting system of waste FRP ships. It's recognized that the location decision of this system is difficult due to the dependence on technical, economical, environmental factors. In this paper, we survey the primary factors of location-economic, life-environment, infrastructure and make up a question for the experts. We also calculate the important weight and related weight using Fuzzy AHP, Limiting probability method and discuss on the calculation results on the proposed sites.
