Evaluation of learning ability of students is classified a step of diagnostic, formative and summative evaluation. This step-by-step evaluation is the standard of synthesis judgement, from a student's prior learning of preparation state to devotion of learning process and even learning result. In this paper, we propose the method of synthesis learning evaluation which is considered evaluation of each step in using fuzzy inference. In order to get objective evaluation of learning ability, we applied to the weights by evaluation steps. And we reflected defuzzification values of final evaluation membership function interval obtained by fuzzy inference about diagnostic, formative and summative evaluation. As a result, it processes definite inference ensures objectivity and shows validity of the synthesis evaluation method.

Various dimensions of watershed structural/non-structural planning can be applied in comprehensive flood mitigation plan in a river basin. Especially structural counterplans have very broad and diverse nature as flood control facilities. It is not easy to find the optimum alternative to maximize the ability of a basin to reduce flood risk using a combination of structural counterplans. In addition, there is no standard for evaluating the performance of structural counterplans and for selecting optimal combination of them. This study focused on how to select the best alternative of a comprehensive watershed structural plan from various flood defense alternative candidates. By introducing an analytic hierarchy process, we would like to show how we decide the best alternative using standard worksheets developed in this study for economics and policy evaluation, and Expert Choice 11.5, which calculates weights for evaluation items. Based on the results from this study, we would like to suggest the best practice of a standardized watershed plan for flood protection.

The Analytic Hierarchy Process (AHP) has been widely used as a comprehensive evaluation method since it can include various evaluation standards of both the public and private sectors. It also provides the objective mathematics to process subjective and Personal preferences of an individual or a group in making a decision. This study tried to use AHP to determine the priority of roads investment, considering various effects in a hierarchy such as environmental effects, residential life, and regional development which has not been treated explicitly. As a case study, roads in Gyeongsangbukdo province have been chosen for the evaluation in this research. For the application, it used relative measurements to estimate the weight of upper level structure, and absolute measurement for low level structure instead of pairwise comparisons.

The purpose of this study was to evaluate the relative weight of infectious disease vulnerability indicators that affect the occurrence and spread of infectious diseases in local communities. For this, the infectious disease vulnerability indicators were classified as facilities vulnerable to spread, vulnerable groups of infections, social vulnerable conditions, and response capabilities based on literature and case review, and the relative weights among indicators were determined using Analytic Hierarchy Process(AHP) by 22 experts. As a result of the analysis, the weight of each sector was found to be the highest in the facilities vulnerable to spread, and the overall weight was highest in the following order: sickbed securing rate(1st), density of religious facilities(2nd), medical personnel rate(3rd), elderly person ratio(4th), and entertainment establishment density(5th). These results can be used to prepare the supporting data necessary for the establishment of infectious disease response policies of local governments.

The object of this study is to determine checklists of agriculture reservoirs which local government managed at routine inspection by Analysis Hierarchy Process (AHP). Suggest definition of agriculture reservoirs and distinguish type of destruction of reservoirs through the analysis of domestic reservoirs or overseas. Draw damage factors of reservoirs from survey on specific area. Combine type of destruction and damage factors of reservoirs for decision of evaluation type of reservoirs. Then, determine optimized routine inspection checklists for agriculture reservoirs and reservoirs by means of AHP considering a weighting.

In this study, we derived selection factors for OTT services based on previous studies and presented an hierarchy process analysis model to calculate the weights for each evaluation. To evaluate the OTT selection factors, OTT customer data was used for the analysis. The results showed that of the first stage factors of economic feasibility, system excellence, convenience, diversity, playfulness, and responsiveness, diversity is the most important. When the weights for first stage and second stage factors were synthesized, entertainment was the most important factor. Lastly, this study analyzed whether there is a difference in the weight of the selection factor for the first stage of OTT service according to gender and age. This study shows which factors consumers prioritize when using OTT services.

For a successful construction project, systematic and objective decision-making is a prerequisite from the planning and designing stages. However, previous LCC analysis methods have focused only on simple cost savings and the accompanying economic efficacy while missing the environmental aspects of a structure. Although recently, a new approach of integrated $CO_2$ analysis has been introduced, which is more advanced than the existing simple LCC methods, it is difficult to collect all of the data necessary for each evaluation item since the product-specific cost is not presented under the LCC. In this research, cost evaluation items were selected by relatively high weights and items with heavy influence over a decision-making process in order to suggest an LCC-LCA integrated analysis model that is useful in comprehensively assessing the economic cost and environmental cost throughout the whole life cycle of a structure. The developed LCC-LCA integrated analysis model was applied to actual practices and compared with previous methods to test the model's effectiveness.

동일하거나 유사한 기능을 수행하는 소프트웨어 제품들 중에서 사용자 요구사항에 가장 적합한 제품을 결정하기 위하여 측정과 평가 및 선정을 실시하는 것을 매우 중요한 일이다. 이러한 소프트웨어 제품의 평가와 선정은 대량 구매시 객관성 확보를 위해 특히 중요하다. 소프트웨어 제품의 평가를 위한 절차는 평가 대상 제품의 속성 결정과 측정, 속성의 중요도에 따른 가중치 부여, 그리고 평가와 선정 모형을 통한 최적제품의 선정이나 우선순위의 결정이다. 본 연구에서는 이러한 절차에 따른 가중치 부여 방법으로는 계층적 분석과정을 이용하고, 제품의 평가와 선정 방법으로는 4개 보상모형과 7개 비보상모형, 그리고 4개의 DEA(Data Evelopment Analysis)모형을 종합적으로 설명한다. 또한 본 연구에서는 위의 15개 평가와 선정모형을 사용하여 Infoworld(Jan.1997)에서 발표한 '문서 작업흐름 관리' 소프트웨어 제품의 속성에 대한 측정결과를 가지고 모형별 적용 결과를 분석한다.
