유역단위의 통합적 치수계획은 고려되는 단위사업의 수가 많고 그 특성도 다양하므로 이들을 조합한 최적의 대안을 수립하기가 쉽지 않다. 최적의 대안수립을 위해서는 홍수피해를 산정하는 것뿐만 아니라 감내할 수 있는 피해의 수준을 결정해야만 한다. 이에 대한 결정은 큰 틀에서 '사회적 합의'라는 방식으로 도출되지만 일차적으로는 기술적으로 가능한 범주에서 경제적 효율성 측면의 분석을 필요로 한다. 본 연구의 목적은 각 단위사업들의 조합이 경제적 효율성을 갖도록 하는 대안수립 방법을 제시하는 것이다. 이를 위해서 치수사업을 투입과 산출에 의한 경제학적 생산활동으로 정의하고 최적사업규모를 대안수립의 원칙으로 제시하였다. 본 연구는 기존에 공학적 측면에만 의존하던 대안수립 방법을 개선하여 경제적 측면에서 최적사업규모를 고려하였다는 데에 의의가 있다. 이러한 대안수립 방법은 하천중심의 소극적 치수계획을 지양하고 피해지역 중심의 유역단위 치수계획 수립으로 전환되고 있는 최근의 정부정책 방향에도 부합하며, 정책수립을 위한 효과적인 수단을 제공할 수 있을 것으로 기대된다.

백화점과 할인점시장이 확대됨에 따라 많은 유통기업들은 여주프리미엄아웃렛과 같은 아웃렛 쇼핑센터 개발에 관심을 가지게 되었다. 개발주체들은 아웃렛 쇼핑센터의 성공적인 개발을 위하여 개발대안들에 대한 소비자의 선호를 파악해야 한다. 본 연구는 컨조인트 분석을 활용하여 아웃렛 쇼핑센터의 개발대안에 대한 소비자의 선호를 분석하였다. 실증분석 결과 아웃렛 쇼핑센터에 대한 잠재 소비자의 선호요인과 관련하여 다음과 같은 연구결과를 도출하였다. 아웃렛 쇼핑센터의 개발대안에 대하여 소비자들은 정상가대비 할인율을 가장 중요한 선호요인으로 평가하는 것으로 나타났다. 다음으로 아웃렛 쇼핑센터의 입지, 아웃렛 쇼핑센터의 입점브랜드가 선호요인으로 나타났다. 이러한 결과를 활용하여 다양한 형태의 아웃렛 개발대안에 대한 소비자의 선호를 시뮬레이션 하였다. 이를 통하여 신규 아웃렛 쇼핑센터의 최적의 개발대안을 도출하게 되었다.

This study sought to search for the new alternatives and direction to develop and strengthening rural youth education in Korea. The study was conducted through literature review on articles, proceedings and other sources relevant to the pending issues and difficulties of rural youth education in Korea. Some of the critical needs for improving rural youth education in Korea included the following aspects or alternatives; 1) Strengthening the partnership between rural adult and youth would be necessary to gain broader support and to establish the increased awareness of adults for rural youth education. 2) Better coordination and cooperative efforts should be emphasized among various programs and institutions in implementing rural youth education policies and programs. 3) Developing a strong link between the agribusiness sector and the rural youth education system should be strengthened to produce the effective results. Further activities to develop and implement diverse programs and projects to cope with new trends In farming and agriculture as well as changing trends in marketing sector of agribusiness and rural communities in Korea. The rural leadership and community networks should be established for improving the effectiveness of rural youth educational activities.

In this research, we develop the model of selecting and setting technology modular alternatives. We compose the selecting process(CHP) after setting technology modular alternatives based on technical couple by Conjoint Analysis(CA). Through this process, we can have several advantages. (1) Increasing the accuracy of R&D project evaluation (2) Declining the load of pair-wise comparison

Nowadays, one of the serious problems in KEPCO(Korea Electric Power Co-Operation) system is the more higher fault current than the SCC(Short Circuit Capacity) of circuit breaker. There are many alternatives to reduce the increased fault current such as isolations of bus ties, enhancement of SCC of circuit breaker, applications of HVDC-BTB(High Voltage Direct Current-Back to Back) and FCL(fault current limiter). But, these alternatives have some drawbacks in viewpoints of system stability and cost. As the superconductivity technology has been developed, the HTS-FCL(High Temperature Superconductor -Fault Current Limiter) can be one of the attractive alternatives to solve the fault current problem. Under this background, this paper presents the EMTDC(Electro-Magnetic Transient Direct Current) model for resistance type HTS-FCL considering the nonlinear characteristic of final resistance value when quenching phenomena occur.

The Analytic Hierarchy Process (AHP), a decision making model, which is more applicable than other methods to R&D project selection, particularly when it is applied to intangibles. The objective of this paper is to develop an extended model of the AHP which Is linked to Cross Impact Analysis to assist in the ranking of a large number of technological alternatives. In this study, we developed a priority setting algorithm which considers the cross-impact of the future technology alternatives and thus developed an integrated cross-impact hierarchical decision-making model, which sets the priority by considering technological forecasting and technology dependency

By investigating various information promotion plans by Taegu Metropolitan City Government, Kyungbuk Provincial Government or by the ministry of Agricultural, Forestry, and Fishery Affairs, this paper intends to analyze current trends of information approached from wider perspective, and to propose multi-layered alternatives which improve informatization promulgation in rural areas of Taegu, Kyungbuk areas. This research proposes following 6 alternatives, as informatization strategies to develop rural economics ; (1) construction of Agricultural Techno Park to advance and develop informatization in rural areas, (2) construction of communication super highway to strengthen information infrastructure, (3) construction of region-specific information system to provide agricultural information unique to its region or areas, (4) provision of agriculture-related information by establishing regional information centers separated by regions like North, South, Eastern regions etc., (5) establishment information, (6) establishment of information gallery of village to provide information needed. And this research also investigates specific contents progresses of various plans by various actors.

In order to improve the recyclability and to reduce the recycling cost and time, the disassembly technology should be systemized because the worn out products can be reused or recycled after disassembly processes. This paper attempts to propose the integrated CATIA-based DfD (Design for Disassembly) support system to promote the disassemblability of products. The system is composed of two modules; evaluation of disassemblability, generation of DfD alternatives. The disassemblability of current vehicle is evaluated to identify the weak point in terms of disassembly using the DELMIA and developed evaluation system. Furthermore a new expert system is developed to propose the optimal redesign rule and principle for generating the DfD alternatives. In order to generate the DfD alternatives, a CATIA-based design support system is implemented. The system can provide quick results and ensure consistency and completeness of the redesign alternatives.

This study developed and calculated alternative evaluation index (AEI) from the effectiveness analyses of alternatives for rehabilitation of distorted hydrologic cycle. The feasible alternatives for the poor-conditioned region in the Anyangcheon watershed were proposed and quantitatively analyzed using continuous water quantity/quality simulation model, Hydrological Simulation Program-Fortran (HSPF). The effectiveness analyses include 355th flow and 275th flow of flow duration curve and number of increased days to satisfy the target monthly flow for water quantity and BOD average concentration, total daily loads and number of increased days to satisfy the target concentration and total daily loads. The feasible alternatives are restoration of covered stream, prevention of streamflow loss through sewers, redevelopment of existing reservoir, reuse of treated wastewater, use of groundwater collected by subway stations and construction of small wastewater treatment plant. Therefore, alternative priority ranking was derived from AEIs. It will be effective to make an integrated watershed management for sustainable development.
