This study aimed to construct an effective decision-making model on selection of cloth stores using AHP technique. The proposed AHP structure consists of three levels. The highest level includes the cloth stores alternative which are department store, specialty store, and a clothes store. The second level consists of the key performance measurements for evaluating the optimal selection of cloth stores, such as location, facilities, product, service, and promotion. The lowest level consists of items which affects the performance measurements in the upper level. The items are convenience location, courteous service, decor/ambience, availability of parking, etc. The data for this research were collected from questionnaires of 132 in Busan. Data were analyzed by frequency and AHP. As the result of this study, 'product' was decided as a most important item in department store, while 'location' was decided as a most important item in specialty store and a clothes store. And 'variety goods' evaluated as that of first priority in the totality evaluation items in department store, but 'convenience location' evaluated as that of first priority in the totality evaluation items specialty store and a clothes store.

Severity and frequency of industrial accidents are typically used to assess the "absolute" risk associated with the industrial machines and devices ("items") which are subject to safety certification or self-declaration of conformity. However, the "relative" risk associated with a particular item can further be assessed based on unit severity and unit frequency where the total number of item in use is taken into account. This study first attempts to estimate the total number of each item in use which was recently selected for safety certification or self-declaration of conformity. The appropriateness of such selection is recapitulated based on the relative risk involved. Analysis results indicate that depending on items, the relative risk is differentiated from the absolute risk. Recent selection of items for safety certification or self-declaration of conformity is then revisited for its validity. The relative risk based on unit severity and unit frequency of industrial accidents, together with the absolute risk, may be used to further categorize items for safety certification or self-declaration of conformity in the future.

The comparative evaluation is the most effective method for site selection because the selection of waste treatment facility is to determine the optimum site out of limited candidate sites. This study adopted the ordinal scale evaluation, one of methods of comparative evaluation. The ordinal scale evaluation aims to determine the investigating items referring to the character of sites, to determine the importance factors for investigating items, and to determine the optimum site according to the quantitative evaluation. This study has focussed on reflecting the opinion of residents to the maximum extent with a weight on social and economic aspects, considering the state of confrontation against each other between the autonomous government organization and local residents, which is being emerged as a social issue relating to the evaluation rating on each item of site selection of an optimum site. Therefore, rational, and clear validity investigations and proper reduction of both time and expenses in site selection as well through this a study.

The purpose of this study is to propose an objective and rational methodology for the selection of proposed sites far the National Trust(NT), which is the new alterative proposal far the conservation of natural environments destroyed by injudicious land development and economic growth. That is to enforce many analysis for the effective estimation of rare ecological and landscape resources and to propose a model based on estimation and united indicators. Using the estimative model, we apply it to the selection of the proposed site in micro scale and simultaneously offer the basic methodology of effective and systematic land conservation in macro scale. The results of this study are as follows: 1) The results of analysis for the reliability of estimative items and indicators, presented no problem in that the coefficient of reliability was over 0.7. 2) The correlation measure of the estimative indicator indicated that 'succession'and 'regenerating restorability' were highly correlative in the item of plants. Another three items showed a tendency to be alike. 3) The results of factor analysis on the characteristics of indicators, classified plants into four categories including a stable factor. The item of animals was classified as a stable and rare factor. The item of landscape was classified as a physical and mental factor and the environment as a pollutional and conditional factor. 4) The model of estimation created through factor analysis was valid for the approval of the regression model because significant probability was 0.00. When we consider the NT proposed site as a complex body that is composed of diverse natural and manmade resources, certainly the synthetic methodology of estimation is needed. If these studies are carried out, NT sites will be selected more rationally and effectively than at present. Consequently, they have the potential to play a core role of natural ecosystem conservation in Korea.

이 연구는 고등학교 생명 과학 I의 지필평가 실태를 조사하기 위하여 일반계 고등학교 10개교를 임의로 선정하여 2013학년도 생명 과학 I의 문제지 33부(선택형 문항 690개, 서답형 문항 162개)를 분석하였다. 문항에 대해서는 Bloom의 신 교육목표 분류체계의 틀과 국가수준 학업성취도 평가의 과학과 평가틀에 근거하여 분류하였다. 선택형 문항의 경우 실제 정답률과 이원목적분류표에 제시된 난이도를 비교하였고, 서답형 문항의 경우 문항유형에 따른 문항 수와 배점을 비교하였다. 서답형 문항 중 서술형 문항에 대해서는 반응의 허용 정도, 자료 제시 여부, 출제 형식에 따라 구분하였다. 지필평가 문항 분석 결과, 서답형 문항의 비율이 19.0%로 선택형 문항의 비율(81.0%)보다 낮았다. Bloom의 신 교육목표 분류체계에 의한 분석 결과, 지식 차원에서 '개념적 지식'에 해당되는 문항이, 인지과정 차원에서 '이해하다'에 해당되는 문항이 많았다. 국가수준 학업성취도 평가의 과학과 평가틀에 의한 분석에서 '지식' 영역에 해당되는 문항이 '탐구' 영역에 해당되는 문항보다 약 9배 많았다. 선택형 문항에서 이원목적분류표에 제시된 난이도와 실제 정답률을 비교한 결과, 일치하는 비율은 41.5%였다. 서답형 문항의 유형에 따른 문항 수의 비율을 비교한 결과, 단답형 문항의 비율이 34.0%였고, 그리기 문항은 '세포와 생명의 연속성' 단원에서 주로 출제가 되었다. 서술형 문항에서 반응의 허용 정도에 따라 분류한 결과, 모두 '응답 제한형'에 해당되었고, 그 중 '내용범위 제한형'(67.3%)에 해당되는 문항이 가장 많았다. 그리고 자료 제시여부에 따라 분류한 결과 '자료 제시형'(65.4%)에 해당되는 문항이, 출제 형식에 따라 분류한 결과 '지식 서술형'(80.4%)에 해당되는 문항이 가장 많았다. 이 연구 결과를 통하여 학교 현장에서 '탐구' 영역에 해당되는 문항을 더 많이 출제할 필요가 있으며, 서술형 문항의 실제적 비중을 높이면서, 다양한 유형으로 출제할 필요가 있다고 생각된다.
