Based on the nonlinear static analysis and the approximate seismic evaluation method adopted in "Guidelines for seismic performance evaluation for existing buildings, two methods to calculate strength demand for retrofitting individual structural walls in unreinforced masonry buildings are proposed." The displacement coefficient method to determine displacement demand from nonlinear static analysis results is used for the inverse calculation of overall strength demand required to reduce the displacement demand to a target value meeting the performance objective of the unreinforced masonry building to retrofit. A preliminary seismic evaluation method to screen out vulnerable buildings, of which detailed evaluation is necessary, is utilized to calculate overall strength demand without structural analysis based on the difference between the seismic demand and capacity. A system modification factor is introduced to the preliminary seismic evaluation method to reduce the strength demand considering inelastic deformation. The overall strength demand is distributed to the structural walls to retrofit based on the wall stiffness, including the remaining walls or otherwise. Four detached residential houses are modeled and analyzed using the nonlinear static and preliminary evaluation procedures to examine the proposed method.

현재의 친환경인증평가 과정은 전통적 수작업에 의한 평가방법으로 많은 시간과 인력을 필요로 하며 평가자의 경력과 주관에 따라 평가 결과에 영향을 끼치게 된다. 이러한 문제점의 해결방안중의 하나로 평가과정을 시스템화하여 평가에 대한 객관성을 부여함으로써 평가결과에 대한 신뢰성을 높일 수 있으며 처리과정의 오류방지나 시간 절약등의 효과를 높일 수 있는 방안이 필요하게 되었다. 따라서 현재 건축설계에 도입되고 있는 BIM 방식의 설계정보를 이용하여 자동화된 친환경인증평가 시스템의 구축 가능성을 타진하고 가능한 분야에 대한 평가시스템을 구축함으로써 친환경인증평가 시스템화의 기반을 마련하고자 하였다.

The preliminary, advanced and final evaluation of R&D project is essential in order to reduce loss of resource and opportunity and to minimize uncertainty resulting from optimal selection and efficient progress of R&D project. This thesis examined characteristics of deterministic evaluation, economical evaluation, and OR-approach evaluation as theoretical methodology of evaluation of R&D project applicable to food industry in Korea by using scoring method, one of deterministic evaluations. In addition, this thesis divided the evaluation factors for preliminary evaluation of R&D project into 5 groups and 30 factors on basis of the environment of domestic companies and set up the standard of each evaluation factors and contains marking-selecting way. But, generally, the evaluation model by this thesis, as the conditions of the business company environment are different to each other, contents to be set up evaluation factors, evaluation standard and decision method conforming to each the environment of the business companies with referring to as one standard of evaluation project for selecting R&D project.

This study was aimed at primarily to develop a tool to evaluate sexuality education and secondarily to test effectiveness through application of developed evaluation tools in elementary school. The results from this study were summarized below: 1. On the basis of targeting the lower grades (1st- 3th year) and the higher grades (4th-6th year) elementary school students' sexuality education guidebooks published by Korea Ministry of Education & Human Resources Development, 71 preliminary items targeting the lower grades, 90 preliminary items targeting the higher grades were developed. 2. Through the validity test about the contents of the preliminary items three times, the items were regulated to 65 items targeting the lower grads and 57 items targeting the higher grades. And then, the preliminary items were re-regulated to 40 items separately. Then, pre-test which targeting each 30 students was enforced. 3.Finally, the evaluation tools for sexuality education that consisted of 40 items targeting the lower grades and the higher grades were developed. 4. eliability test of the developed tools, sexuality education evaluation tools showed alpha coefficient of internal consistency were 0.8355 (for the use of the lower grades) and 0.8881 (for the use of the higher grades). 5. o apply the developed sexuality education evaluation tools, 10-times sexuality education were carried out class unit and pre-post test were done using same questionnaire, which contains developed tool, there were significant difference in low grade (t=16.548, p=0.000), high grade (t=14.773, p=0.000). The results of this study suggest that the evaluation tool for sexuality education in elementary school may be a useful tool with a high degree of reliability and validity. In this sense, the evaluation tool for sexuality education developed by this study can be effectively utilized in Korea elementary schools.

The purpose of this study is to develop an evaluation index for evaluating the economic value of libraries. To this end, a preliminary evaluation index was derived from analyzing a total of approximately 60 domestic and foreign papers that examined the value of libraries. Based on the derived preliminary evaluation index, 11 experts were selected and the final evaluation index was developed by conducting the Delphi survey for 3 times. The final evaluation index consists of four evaluation areas, such as the economic value of the public library, economic revitalization, manpower development and job creation, and the improved investment value, seven evaluation items, and 22 evaluation indices. In the future, it will be necessary to conduct research to measure the economic value of public libraries.

개착식 구조물이나 교량 구조물과 같은 도시철도 시설물을 대상으로 시행한 내진성능 예비평가체계는 도시철도 시설물이 지녀야하는 특성을 고려하지 못하는 문제점이 있다. 특히 교량 구조물의 경우에는 도로교의 내진성능 예비평가체계를 그대로 적용하여 사용하고 있어 도시철도 교량 구조물에 적용하기에는 비현실적인 평가 항목들이 존재한다. 그리고 각 시설물에 대한 예비평가 항목들을 산정할 때 적절한 근거가 없어 평가 결과의 신뢰성을 확보하지 못하고 있는 실정이다. 따라서 본 연구에서는 기존 내진성능 예비평가 체계의 문제점을 분석하고 수정(개정) 안을 제시한다.

Nonlinear static analysis and preliminary evaluation were performed in this study to evaluate the seismic performance of unreinforced masonry buildings subjected to various soil conditions based on the revised Korean Building Code. Preliminary evaluation scores and nonlinear static analyses indicated that all buildings were susceptible to collapse and did not reach their target performance. Therefore, retrofit of those building models was carried out through a systematic procedure to determine areas to be strengthened. It was possible to make most building models satisfy performance objectives through the reinforcement alone of damaged external shear walls. However, the application of a preliminary evaluation procedure to retrofit design was found to be too conservative because all the retrofitted building models verified with nonlinear static analysis failed to satisfy performance objectives. Therefore, it is possible to economically retrofit unreinforced masonry buildings through the fortification of external walls if a simple evaluation procedure that can efficiently specify vulnerable parts is developed.

The strategy for the management of earthquakes is shifting from post recovery to prevention; therefore, seismic performance management requires quantitative predictions of damage and the establishment of strategies for initial responses to earthquakes. Currently, seismic performance evaluation for seismic management in Korea consists of two stages: preliminary evaluation and detailed evaluation. Also, the priority of seismic performance management is determined in accordance with the preliminary evaluation. As a deterministic method, preliminary evaluation quantifies the physical condition and socio-economic importance of a facility by various predetermined indices, and the priority is decided by the relative value of the indices; however, with the deterministic method it is difficult to consider any uncertainty related to the return-year, epicenter, and propagation of seismic energy. Also this method cannot support tasks such as quantitative socio-economic damage and the provision of data for initial responses to earthquakes. Moreover, indirect damage is often greater than direct damage; therefore, a method to quantify damage is needed to enhance accuracy. In this paper, a Seismic Risk Assessment is used to quantify the cost of damage of road facilities in Pohang city and to support decision making.

본 연구의 목적은 도서관법 개정에 따라 의무 적용되는 공공도서관 설립 타당성 사전평가가 도서관의 질적인 측면을 개선할 수 있을지 파악하는 것이다. 이에 도서관법 개정 전 같은 목적으로 시행되었던 공공도서관 건립지원 사업 사전평가의 사례 분석을 통해 사전평가의 실효성을 분석하였다. 사전평가를 거쳐 건립된 도서관들의 경우 도서관법 시행령에서 요구하는 법정 사서 최소 기준 3명을 대부분 확보하고 있어 기본적인 도서관 인력 확보에는 도움이 된다고 할 수 있었다. 하지만 당초 계획하였던 만큼의 인력을 확보하여 운영하는 도서관은 거의 존재하지 않았고 신청서에는 도서관 운영을 직접 운영하겠다고 신청하였지만 실제 개관 시 위탁운영으로 변경된 사례도 있어 사전 검토 내역이 충실히 반영되지 않았다는 측면도 있었다. 본 연구는 사례 분석을 통하여 형식적으로 거쳐야 하는 사전 절차가 되지 않도록 법 개정에 따른 현실성 있는 사서 배치 기준의 재확립과 도서관 등록제를 활용한 사후평가 도입을 제안하였다.
