바람직한 해상교통안전진단제도 정립을 위해 보다 종합적이고 체계적인 검토가 필요한 바, 본 연구에서는 메타평가에 관한 이론을 적용하여 설계된 메타평가 모형을 그동안 실시된 우리나라 해상교통안전진단에 적용, 종합적으로 분석 평가하여 해상교통 안전진단제도의 개선방안을 도출하였다. 메타평가는 평가의 질적 개선을 통한 평가결과의 활용도를 제고하기 위하여 평가수행뿐만 아니라 전반적인 평가시스템을 포함한 평가로 그 타당성을 규명하는 일련의 작업으로서 본 연구에서는 문헌연구와 전문가검토, 설문조사 등의 방법을 활용하여 진단활동에 대한 전반적인 평가를 실시하여 개선방안을 마련하였다. 특히, 개선의 시급성을 정량화함으로써 개선 우선순위에 대한 정책적 시사점이 클 것으로 기대한다.

유역종합치수계획 수립시 유역내 해당 지점에서의 하도와 유역에 대한 홍수량 배분은 원활한 목표연도 홍수량 처리, 치수안전도 증대, 치수경제성 등을 고려하여 하도 및 유역에서 실현 가능한 모든 홍수방어대안 등을 검토하여 적절한 홍수량이 분담되도록 결정되어야 한다. 그러나 기존 문헌 및 연구에서 제시하고 있는 홍수량 배분에 대한 규정은 구체적이지 못하고 추상적이며 계획수립시 하도 홍수소통능력에 대한 객관적인 기준과 고려없이 하도분담량을 설정하고 있다. 이에 본 연구에서는 하도 홍수소통능력 평가에 대한 합리적인 기준설정이 필요하다고 판단되어 기존의 문헌 및 사례 등을 종합 분석하여 하도의 홍수소통능력 평가기법을 개발하였다. 하도 홍수소통능력의 판단기준은 하천내 유수의 소통능력은 물론, 하도내 수위가 높음으로 인해 내수배제가 원활히 이루어지지 못해 발생하는 홍수피해를 최소화할 수 있도록 5단계로 구분하였다. 그리고 제내지의 토지이용현황, 자산분포와 인구밀집도 등을 고려한 평가기준이 될 수 있도록 하였다. 내수에 대한 하도 홍수소통능력 검토시 도시하천의 경우에는 홍수피해 위험이 높고 자산이 많이 분포되어 있는 하천구간은 소파기준에 해당하는 침수심 0.5m 기준을 적용하였다. 그리고, 농경지하천의 경우는 농경지 침수시간에 따른 작물 피해액 기준을 도시하천의 개념과 유사하게 적용하여 홍수피해잠재능이 높은 지역에 위치한 하천의 경우는 침수지속시간이 24시간 이내가 되도록 적용하였다.

Transparency on the Total System Performance Assessment (TSPA) is the key issue to enhance the public acceptance for a radioactive repository. To approve it, all performances on TSPA through Quality Assurance is necessary. The integrated Cyber R&D Platform is developed by KAERI using the T2R3 principles applicable for five major steps : planning, research work, documentation, and internal & external audits in R&D's. The proposed system is implemented in the web-based system so that all participants in TSPA are able to access the system. It is composed of three sub-systems; FEAS (FEp to Assessment through Scenario development) showing systematic approach from the FEPs to Assessment methods flow chart, PAID (Performance Assessment Input Databases) being designed to easily search and review field data for TSPA and QA system containing the administrative system for QA on five key steps in R&D's in addition to approval and disapproval processes, corrective actions, and permanent record keeping. All information being recorded in QA system through T2R3 principles is integrated into Cyber R&D Platform so that every data in the system can be checked whenever necessary. Throughout the next phase R&D, Cyber R&D Platform will be connected with the assessment tool for TSPA so that it will be expected to search the whole information in one unified system.

The final goal of this research is to establish the relative dangerousness D/B for factors on seakeeping performance. This D/B is, essential to develope the seakeeping performance evaluation system built-on-ship. The system is composed of the apparatus for measuring a vertical acceleration to be generated by the ship's motions, computer for calculating the synthetic seakeeping performance index and monitor for displaying the evaluating diagram of navigational safety of ship. In this paper, a methodology on the establishment of the relative dangerousness D/B for factors on seakeeping performance is presented by a numerical simulations, playing an important role on the algorithm of the program for calculating the synthetic seakeeping performance index. Finally, It is investigated whether the relative dangerousness D/B can be realized an accurate values according to the loading conditions, weather conditions, wave directions and present ship's speed of a model ship.

In this study, we made the analysis of the relation with mathematical tests and scholastic attainments of gifted students using the results of entrance end comprehensives exams and so on in science education center for gifted youths. For this, we firstly made an analysis of correlation between math and math, math and science and science and science using the test results. And then, we interviewed four students. From this, we found followings. First, in every assessment except for those carried out during the semester in the center, we saw a very low or negative correlation between the students' grades in math and that in science. Second, in contrast to the correlations among other assessments, a high correlation of the students' grades in math and science appeared in regard of the assessments carried out during the semester in the center. Third, correlations between the grades of assessments in mathematics were much lower than that in science. Fourth, many students thought the assessments in the center were not as valuable as those in their schools, which are referred to in getting into a school of high grade. So some of the students who gained excellent grades showed a relatively low achievement. Fifth, students in the center regarded a vigorous communication and inquiry learning on enriched themes as the biggest merit of attending the center.

In this study, on the basis of an analytic hierarchy process (AHP) method and through a questionnaire on subjective preference and importance, various power supply systems were comprehensively compared with multiple decision criteria such as environmental, social, healthy, and economic viewpoints and then overall priority was assessed. When a decision-making problem is modelled by a hierarchy structure, the AHP method is regarded as a useful tool for extracting subjective opinions via the aforementioned questionnaire. Here, the overall preferences were obtained by linearly aggregating weighting vector and preference matrix. The energy systems such as nuclear, coal, and LNG power plants were selected because they took share over 90% of domestic electricity supply in Korea. Furthermore, wind power and photovoltaic solar systems were included as representative renewable energy systems in Korea. According to the results of this demonstration study, the following comprehensive comparison indicators were yielded: 1) weighting factors for 4 types of main criteria as well as for 11 types of sub-criteria; 2) preference valuation for 7 types of energy systems under consideration; 3) overall score for each energy systems.

In this paper, a study was conducted on the method of establishing the master plan standard for rational decision-making about utility tunnel construction in the existing urban. In the previous study, the optimal route was selected by the feasibility assessment. However, in order to increase the objectivity of the installation conditions of the utility tunnel in the master plan standard, comprehensive evaluation of the results by feasibility and economics analysis calculates the overall ranking for all sections analyzed. In addition, based on the results of the comprehensive evaluation, a method for establishing a mid·long term investment plan was introduced after reviewing the project to be conducted in the region. Additionally, in order to review the establishment of the standard suggested in the paper, an analysis was conducted by applying the master plan procedure to the northwestern urban zone of seoul.
