This paper presents the development and application of a riparian buffer zone design model(RBZDM). The model was developed as a decision-making tool for watershed management, by integrating geographic information system(GIS) and analytical hierarchy process(AHP) theory. Several factors for watershed management, such as pollution removal capacity, land aquisition cost, distribution of point and non-point pollution sources, and possibility of new pollution source location, were analyzed based on AHP theory. The vegetated buffer zone width was designed using GIS-based riparian buffer analysis. The developed model was applied to the Kyoungan Stream watershed, which is an important part of Paldang lake catchment area. The Kyoungan stream watershed was divided into sixteen subbasins. Six of them belong to the main stem, where the model was applied. Ten alternatives of buffer zone width and five hierarchial levels were designed. The relative importance and the relative preference were computed by pair-wise comparison of evaluation criteria given in hierarchial levels. The buffer zone width was determined by linear function of the given alternatives and relative preferences. From this study, it was determined that the six buffer zone widths of Kyoungan main stems would be 1,594, 1,744, 1,856, 1,782, 1,338, 1,780 meter, from upstream to downstream.

This study is to estimate the factor weights of the reasons for decreases in marine fishery resources using the Analytical Hierarchy Process. Furthermore, it classifies 20 fishes under a fishery resource recovery plan into various groups of fishes according to these factor weights using the non-hierarchial cluster analysis. The factors of decreases in marine fishery resources are identified as bio-ecological, technology-system, economic-business, and fishing village-society factors. Two of the most important factors of decreases in resource are turned out to be the economic-business and bio-ecological factors, estimated as 31% and 30% respectively. The technology-system and fishing village-society factors are estimated as 21% and 18% respectively. The study utilizes non-hierarchical cluster analysis in order to classify 20 fishes into 2, 3, and 4 groups. K-means cluster analysis is applied for grouping in conjunction with ANOVA to identify statistical differences in factors. Once again, the economic-business and bio-economic factors play main role in grouping 2-groups of fishes case. The third group of fishes in addition to the previous 2 groups of fishes appears as those 4 factors of decrease evenly play about the same role at a 3-groups of fishes case. Finally, the economic-business and bio-economic factors are turned out to be evenly important in the 4th group once there are 4-groups of fishes.

본 연구의 목적은 해운기업의 선급결정요인을 확립하고 계층적의사결정(AHP) 기법을 활용하여 요인별 상대적 중요도를 고찰하는 것이다. 선급결정요인의 계층구조에 대한 선행연구가 부족하여 관련 산업 연관도에 따른 선급의 주요 활동, 선급 업무 프로세스 및 서비스 전달 과정을 참조하여 요인들을 식별하고 주요인과 세부요인으로 분류하였다. 이를 선급 관련 업무 종사자를 대상으로 설문하여 최종 확정하였고, AHP 분석을 위하여 해운 관련 업무 종사자 대상 설문을 진행하여 다음과 같은 결론을 도출하였다. 선급결정요인 중 주요인의 중요도는 기술 및 검사 서비스 0.373, RO 기능 0.284, 비용 0.177, 시장(연관산업)의 기대 0.167인 바, 기술 및 검사 서비스에 대한 상대적 중요도가 아주 높게 나타나 BWM, 황산화물과 같은 환경규제와 자율운항선박, 친환경연료추진선박 등 미래 기술선도 선박에 대한 기술 협력 등 해운 시장의 변화와 트렌드를 반영함을 알 수 있었다. 세부요인의 복합가중치는 PSC 대응 능력 0.144, 기술 서비스 0.143, 금융기관/화주/조선소 등의 요구 0.090, 선급유지비용 0.087, 검사 네트워크 0.086, 검사원 역량 0.085, IMO/정부와의 협력 0.072, 정부 검사권 수임 0.067, 선급의 영업력 0.058, 최초검사비용 0.052, 평판과 공신력 0.040, 선급관련부대비용 0.038, 관련 산업과의 유대 0.037 순서로 나타난 바, 해운기업은 항만당국의 PSC 검사에 따른 출항정지방지와 기술서비스를 중요하게 생각하며, 금융기관/화주/조선소 등의 요구, 선급유지비용, 검사 네트워크, 검사원 역량을 높은 우선순위로 판단함을 알 수 있었다.
