세계 물 시장은 지속적으로 성장하고 있는 추세로 현대경제연구원에서는 연 평균 5.5%씩 성장할 것이라고 예측한 바 있다. 또한 국내 수자원 개발은 거의 포화 상태에 도달하여 수자원 기업들이 해외 수자원 산업진출을 다각적으로 추진하고 있으므로 해외 수자원 사업에 대한 관심이 더욱 커질 전망이다. 해외 수자원 산업에서 국내 기업이 어려움을 겪는 부분 중 하나는 타당성 조사로 개발도상국에서 좋은 품질의 기상 및 수문 관측 자료를 확보하는 것이 어렵기 때문이다. 국내 기업들이 진출한 주요 해외 시장은 아시아와 아프리카이며, 진출 사례가 많은 아시아 지역에는 비교적 기상 및 수문자료 확보가 용이하나, 아프리카 지역은 자료의 확보가 어려운 상황이다. 특히 아프리카 지역은 수자원 현황이 열악하고 개발가능성이 높아 향후 국내 기업의 진출이 활발할 것으로 예측되는 지역으로 수자원 산업 진출을 위한 기상 및 수문자료 확보를 위한 노력이 필요하다. 본 연구에서는 해외 수자원 산업 진출의 기초자료 확보를 위해 아프리카 지역의 기상, 지형, 토양자료를 수집하고 수문자료 생산을 위한 지표수문해석 모델의 적용성을 평가하였다. 지표수문해석 모델로는 국내외에서 전지구 규모 수문해석에 활용성이 높다고 알려진 VIC (Variable Infiltiration Capacity)를 활용하였으며, 물수지 모의를 수행하였다. 기상, 지형, 토양자료는 미국 CPC (Climate Prediction Center), UMD(University of Maryland), FAO (Food and Agriculture Organization)의 전 지구 자료를 활용하였다. 아프리카 주요 유역에 대한 VIC 모델 적용성 평가결과 유출해석의 정확도가 유의미한 것으로 나타났다. 본 연구에서는 아프리카 대륙 규모의 기상, 지형, 토양자료를 확보하고 수문자료 생산 체계를 구축하였으며, 연구결과가 향후 국내 수자원 기업의 해외진출 및 전 지구 규모 수문연구의 기초자료로 활용될 수 있다는 점에서 가치가 있다.

With the expansion of Voucher program, academic and practical concerns of performance evaluation of voucher service has been more emphasized. Accordingly, client satisfaction survey are expanding these days, but the study of client satisfaction as a performance indicator aimed at service client has not been yet conducted systematically. The purpose of this study is to develop Satisfaction Index, targeting at client of community-development voucher program in Community Service Investment Project conducted by the Ministry of Health and Welfare. Data were collected from 1800 client of community-development voucher program. This study summarized theoretically many kinds of satisfaction measurement and composed the Satisfaction Index reflecting characteristics of Voucher. By the item analysis and reliability analysis, the element satisfaction was identified as homogeneous items. General satisfaction were obtained using element satisfaction and overall satisfaction, it was found to be valid through the evaluation of convergent and discriminant validity as a tool for satisfaction. This study suggest using the '1step weighted approach' than '2step weighted approach' having weakness of complex overlapping manner.

Purpose: This paper discusses the intrinsic assumption of one-dimensional relationship between the upper and lower levels in AHP(Analytic Hierarchy Process) for the Preliminary Feasibility Study of National R&D Program. This assumptions has not been questioned in academia and industry so far. Methods: This discussion is induced by understanding the Theory of Attractive Quality (Kano et al. 1984) and explains the limitation of AHP in the preliminary feasibility study of national R&D program. Results: In this paper, we propose a new questioning method based on two dimensional perspective, which is named as 2D-AHP (two dimensional AHP), to overcome the limitation. The main idea stems from the observation that the relationship between the upper and lower levels in AHP can vary depending on the subject of R&D. Conclusion: The two dimensional perspective pointed out in this paper should be more deeply studied in the field of MCDM(multi-criteria decision making) since it can be applied to the more general problems in human decision making.

This paper suggests a way of estimating the value of interclass equity improvement by railway operations. Equity is understood in this paper in the context of a mobility gap between classes. The value of the reduced mobility gap by railway operations is interpreted as an increase of social equity. In particular, the unit value of equity improvement by rail services is quantified based on the amount of fare reduction through public service obligations. The difference in the surplus calculation between elastic and inelastic demands relative to the reduction is also discussed. The result of this study is expected to be helpful of performing more cautious appraisal for rail investment schemes.

This paper aims to review the regulations in the field of science and technology administration, especially the legal regulations in the management of public technologies. For this purpose, after reviewing the legal system and contents of regulation, analyze and estimate the adequacy and validity of them. So that, in this paper it is layed emphasis on that whether the regulation system is proper in point of legalism or theory of regulation law, and the regulations are appropriate when comparing with that of foreign countries, and the improvement is necessary in operating regulation system itself.

The cost-effective reduction of greenhouse gas(GHG) emission to avert the most severe impacts of climate change remains one of the widely accepted priorities for global action. In order to facilitate cost-effective abatement strategies, the Kyoto Protocol introduced three mechanisms, or flexible instruments, the Emissions Trading(ET), the Joint Implementation(JI) and the Clean Development Mechanism(CDM). The CDM enables Annex I countries to the Kyoto Protocol to partially meet cost-effectively their emission reduction commitments by undertaking GHG mitigation Projects in developing countries, which do not have any GHG abatement obligations and where the emission reductions are cheaper. One of the major barriers hampering the wide spread implementation of CDM is the high transaction costs associated with the initial identification of promising CDM projects. This paper presents development of a pre-validation program of CDM. The developed program may provide a useful aid to potential investors and project developers as a supportive pre-evaluation tool, and may become an effective tool for the promotion of renewable energy and fuel switching projects.

A marine ranching project in Tongyoung was established in 1998, lasting 9 years to 2006. Project activities included the deployment of artificial reefs, the release of young fishes like jacopever and rockfish, and input/output control for specific marine ranching areas in Tongyoung. This report focuses on the economic feasibility of the project in hindsight. Analysis concentrates on three aspects; (a) direct economic benefits, such as increasing effects of fisheries income and savings in harvesting costs, (b) indirect benefits, including increasing effects of recreational fishing and saving R&D costs, and (c) costs, including releasing and purchasing costs of artificial reef and juvenile fish, R&D costs, maintenance costs and harvesting costs. Results show that NPV=4.7 billion won, IRR=8.55% and B/C ratio=1.286 under Scenario 1, which considers the saving effects of R&D costs, and NPV=0.9 billion won, IRR=6.03% and B/C ratio=1.11 under Scenario 2, which does not consider the saving effects of R&D costs, based on 5.5% of the social rate of discount. According to sensitivity analysis, the economic feasibility is very sensitive to the recapture rate.

It is essential to establish some systematic counterplans to diminish such damages of large-scale tidal invasion on coastal lowlands considering the recent weather conditions of growing scale of typhoons. Therefore, the purpose of this research is to make the counterplans for prevention against disasters fulfilled effectively based on the data conducted by comparing and analyzing the accuracy between observation values and the results of estimating the greatest overflow area according to abnormal tidal levels centered on Masan area where there was the severest damage from tidal wave at that time.

In the current marketplace, there are maturity models, standards, methodologies and guidelines that can help an organization improve the way it does business. All SPI models including ISO/IEC I5504 and CMMI provide the capability level of software process. However, most available improvement models focus on a specific goals and Practices of the processes So my assessors need an objective process measure how to estimate achievement of goals and practices. We proposed quantitative process capability metric (PCM) which can determine the degree of capability And the effective measuring approach help SPI assessor as well as organization unit.

This paper presents the application of fuzzy set theory in multi criteria decision making (MCDM). FAHP (Fuzzy Analytic Hierarchy Process) method was used to rank alternatives to find the most reasonable and efficient way of agricultural reservoir water resources assessment. 6 criteria and 10 subcriteria had been identified and compared to secure agricultural water resources. Fuzzy numbers and linguistic variables were presented to address inherently uncertain or imprecise data. Comparison analysis of decision making method was also carried out to find a way of suitable decision making and validity of FAHP was discussed.
