최근 들이 우리나라는 여러 하천을 자연형 하천으로 정비하고 있다. 자연형 하천은 콘크리트로 정비된 하천에 내해 여러 가지 친환경적 공법을 적용함으로서 자연과 가까운 하천으로 복원하려는 목표로 여러 곳에서 시공되고 있다. 자연형 하천 공사로 인해 변화된 하천의 환경을 조사${\cdot}$분석하여 공사로 인한 효과를 분석함으로서 하천공사의 타당성을 검증해야 할 것이다. 공사 효과의 분석은 공사후 하천의 생태계를 평가함으로서 이루어지는데 생태계 중에서 어류가 차지하는 역할이 매우 중요하다. 따라서, 하천공사후 어류서식처에 대한 평가는 하천의 종합적인 평가시에 큰 의미를 갖는다고 할 수 있다. 본 연구에서는 전라북도 순창군에 위치하고 있는 경천을 대상으로 자연형 하천 공사후의 하천에 대한 어류서식처 평가를 실시하였다. 평가를 위해 사용한 방법은 미국 USGS에서 개발되어 사용되고 있는 물리적서식처 모의 시스템인 PHABSIM 모형을 이용하였다. 3년동안의 모니터링을 통해 우점종인 파라미와 갈겨니에 대해 치어기, 성장기, 성숙기 단계에 내한 서식처와 유량의 함수를 개발하고 어류의 성장단계별로 최적유량을 산정하였다.

해양유류오염사고 유출유 피해 위험도 산정을 위한 평가기법을 연구하였다. 본 연구의 위해도 평가에서는 과거 사고 사례에 근거하여 선정한 사고 해역에 대하여 여러 경우의 유출유 확산을 계산하고, 계산 결과를 통계 분석하여 유출유의 피해 가능성, 도달시간, 피해 규모 둥을 산정한다. 유출유의 피해 가능성, 도달시간, 피해규모는 환경민감자원 현황에 근거한 해역별 해안 및 어장 양식장을 대상으로 산정하며, 각 해역별 피해 정도를 비교함으로써 해역별 위해도를 산정한다. 이러한 결과는 특정 유류오염사고에 대한 보다 객관적이고 종합적인 피해 위험을 제시할 수 있으며, 실시간 피해 위험 예측과 연계하여 보다 타당성 있는 유류오염사고 위해도 평가 결과를 제시할 수 있다.

The purpose of this study is to suggest the subject and standards of evaluation on integrated IR interface. For this study, we studied the preceding research about major IR interface models. We took the survey for interface elements which were verified by experts. These interface elements are divided twe viewpoints. One is the cognitive viewpoints which are the page design, content design, site design, output form, usability and aesthelic facet. The other is the objective viewpoints which are page design, dontent design, site design, output for and usability. We found that these evaluation elements have a crediblilty.

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.

The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present since May 27th, 2009. But recently, there's a controversy about whether it has been performed properly or the results is significant. These new discussions were arose from lack of validity and appropriateness we had yet to find. At this point, it needs to establish sound MTSA scheme through the comprehensive review. This research developed a suitable meta-evaluation model for MSTA with applying theory of the teta-evaluation, that is the evaluation of evaluations and verified by using meta-evaluation methods like as literature studies, expert reviews, surveys and etc. The results of this study can be used to evaluate MTSA activities and it will contribute to improving MTSA scheme.

A balanced evaluation system for a bus route network was proposed for a mid-sized suburban city. The evaluation system consists of 7 criteria-accessibility, riding comfort. transfer rate, directness of route, productivity of operation, regional equity, and minimum requirement of bus fleet - and quantitative indicators representing each of the criteria. The proposed system was applied in Siheung, a suburban city in Seoul Metropolitan Area. Four alternative scenarios of bus route network including the existing one were evaluated. The results showed that the suggested criteria and indicators are acceptable for the evaluation of a bus route network. In order to enhance the proposed evaluation procedure, further studies on the normalization of produced values and weights for each of the indicators are needed.

수자원사업은 합리적이고 신뢰성 있는 의사결정이 필요한데 그동안 주로 경제성분석에 의존하여 왔다. 본 연구는 경제성분석위주의 기존 방법을 탈피하여 사업 필요성과 투자 타당성을 다양한 각도로 평가할 수 있는 합리적이고 객관적인 수자원사업 대안선정과 투자우선순위결정 방법을 도출하고자 하였다. 이를 위해, 대안 간에 동일한 기준으로 종합평가점수를 산정하여 우선순위를 결정할 수 있도록 다기준의사결정모형을 개발하였다. 적용결과는 취약성 기준에 큰 영향을 받으며, 정책적 기준, 경제성 기준의 순으로 분석되었다. 이는 전문가 설문에 의한 평가기준별 가중치의 영향으로, 수자원사업은 단순히 경제성 분석만으로 평가를 해서는 안 됨을 의미한다. 본 연구는 대규모의 예산이 투입되는 수자원사업에 대한 효율성과 취약지역에 대한 형평성을 제고하는데 기여할 수 있을 것으로 판단된다.

This study aimed to analyze the appropriateness of the criteria and methods of the feasibility study for national park re-planning. The rate of 'release area' was derived at a lower rate in the absolute evaluation (the second) than the relative evaluation(the third) Seoraksan and Juwangsan National Parks as well as Gayasan National Park. Despite the third evaluation method aiming to maintain park area through retention by setting the areas available for release as 10% rather than applying release, it was found that the absolute evaluation method did not derive more areas available for release. When the second and third ecology-based assessments were applied to study sites, both second and third ecological-based assessments showed that the actual release areas were not reflected in the extraction in 2011. Consequently, it was found that the ecological-based assessment was only a means of assistance instead of a means of critical decision-making for determining the release area. From the district adjustment of the park planning easibility study, it can be determined that interactive exchange and priority application of release criteria as external factors acted more significantly.

This study aims to prepare an objective project basis by reviewing the feasibility of reconstructing and remodeling Greensmart Future School project for S High School's main building, which was built more than 40 years ago, in Incheon Metropolitan City, and to apply and review an effective methodology for determining renovation and remodeling. To this end, the feasibility of reconstruction and remodeling was evaluated in the long term by synthesizing the results of quantitative evaluation through economic review and qualitative evaluation through educational functional review. As a result of the study, it was found that the reconstruction plan was advantageous throughout all alternatives in terms of economic costs, and the field survey indicated limitations in spatial functions to support students' various educational activities and applying new directions, especially the 2022 revised curriculum and high school credit system.

This study presents plans to prevent environmental noise by using noise maps when establishing development projects and targets strategic environment assessments for urban master plans and environmental impact assessment for urban development projects. Strategic environment assessments for urban master plans include the examination of plan validity and location appropriateness in consideration of the effect of environmental noise by comparing development plans with noise maps, and the establishment of long-term measures through comprehensive assessment of present noise conditions and noise effects from development plans. Environmental impact assessments for urban development projects propose enforcement plans, including analysis of present noise conditions around development areas, overall evaluation of present noise conditions and the noise effect from development projects, and selection of optimal measures by comparing noise maps with various alternatives.
