In supply chain management, supplier capacity is very important to meet the customer demand quickly. This paper studies a supplier evaluation structure and then suggests a methodology using fuzzy theory for selecting an effective supplier. Several quantitative and qualitative evaluation factors should be analyzed in the evaluation structure. The qualitative factors includes not only product and service qualities but financial condition. The methodology deals with both the quantitative and qualitative factors together through fuzzy inference. A case study is also presented to show how to choose the best one among potential suppliers.

In conventional probability-based quality evaluation of products with qualitative characteristics, many factors that affect the evaluation are not easily represented quantitatively, because the relation between reliability of human evaluator and each of these factors is not clear. In order to evaluate the quality of product with qualitative characteristics quantitatively, in this paper, the relation is represented as the shape of possibility distribution function of fuzzy set on the interval [0,1]. Furthermore, fuzzy reasoning is used to obtain the estimates of quality characteristics. And, it is supposed that many quality characteristics affected by the above factors are connected with the final characteristic through hierarchical structures. Finally, using the estimates gained from the final evaluation, qualitative characteristics are evaluated by use of concept of pattern recognition.

Purpose: The purpose of this study was to understand the process of exercise adherence in middle aged women. Methods: The qualitative theme analysis method was used. The participants were 11 middle-aged women who had exercised over 6 months. Data were collected through in-depth interviews and recorded by and transcribed immediately. The data were coded with similar meaning and analysis themes with the constant comparative method. Results: The core theme was Stepping Stones Across the Stream (SSAS). The Stone means the adherence factors in exercise. The stream means the interrupting factors in exercise adherence. The subcategories were 1) feeling of developmental crisis, 2) searching for exit (from the developmental crisis), 3) finding a surprising new world (full of fun), 4) confronting the situation of dropout, and 5) adherence to exercise by SSAS. Conclusion: The predisposition of fun in middle aged women for the adherence of exercise should be explored along with more adherent factors.

최근 국가연구개발의 집행예산은 증가 추세에 있고, 이에 따라 국가연구개발사업의 양적 성과 또한 증가하고 있으나, 질적 성과의 증가세는 양적 성과 대비 취약한 것으로 나타나고 있다. 특허등급 및 기술이전효율성이 낮은 기술 등 질적 성과 부진의 원인으로 '건 수' 위주의 성과평가에 대한 개선 필요성이 제기되고 있으며, 이에 대한 대응으로 다양한 '질적 성과지표'를 이용한 성과평가가 도입되고 있다. 본 연구에서는 여러 질적 성과지표 중 주요국(미국, 유럽, 일본) 특허청에 모두 출원하여 특허의 해외경쟁력을 측정할 수 있는 '삼극특허' 창출 과제를 대상으로 연구개발사업의 질적성과 평가를 위한 성과지표로서 삼극특허에 영향을 미치는 요인을 분석하였다. 분석결과, R&D규모 요인 및 과제특성 요인 중 일부는 삼극특허 창출에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 본 연구는 성과분석 측면에서 선행연구가 상대적으로 미진한 삼극특허를 관심대상으로 확장하고, 삼극특허 창출의 영향요인을 선형회귀분석(OLS)을 통해 살펴본 초기연구라는 점에서 의의가 있다.

오늘날 시스템 사용에 있어 가장 큰 문제 중의 하나는 사용자의 요구를 잘 반영하지 못하는 데에 있다. 이러한 사용자의 요구를 반영하기 위해 기존의 많은 연구들은 기기나 서비스 자체에 초점을 두어 중요한 사용 품질요인을 규명하여 왔다. 그러나 모바일 컴퓨팅 서비스는 언제 어디서나 사용이 가능하기 때문에 사용 품질요인이 기존의 정보 시스템과는 다르게 나타나게 된다. 이러한 상황에도 불구하고 기존 연구들은 사용 환경을 고려하여 중요한 사용 품질요인을 도출하기 보다는 기기나 서비스 자체에 초점을 두어 연구를 진행하였다. 본 연구에서는 모바일 컴퓨팅 서비스를 대상으로 모바일 컴퓨팅 서비스 특성에 맞는 중요한 사용 품질요인을 도출하고자 하였다. 이를 위해 대표적인 모바일 컴퓨팅 서비스로 모바일 데이터 서비스를 선정하고 모바일 데이터 서비스 사용자를 대상으로 맥락 집중 인터뷰를 실시하였다. 인터뷰 실시 후 분석 결과, 모바일 컴퓨팅 서비스는 기존 정보 시스템에서 중요하게 나타났던 사용 품질요인과 다르게 나타났다.

The purpose of this study was to investigate the relationship between the quantitative analysis of biomechanical movement and the qualitative analysis of video software in order to evaluate for the walking movement. The fourteen collegiate students who agreed with the purpose and method of this study participated as subjects. The slow walking and fast walking of the subjects in the place of experiment were photographed, and calculated several mechanical factors. This empirical evidence from the experiment indicated the significant difference(p<.001) between each distant factors of the walking movement for both analyses methods, but there was no statistically significant difference between the spacial factors observed in the experiment. For more detail, no significant difference between the walking ratios that expressed the coordination between stride length and stride frequency was found. The findings also indicated the high coefficient of correlation(over r=.9) which supports higher explanation force for the biomechanical method and the Dartfish video software method. Therefore, if the data was gathered by using the proper experimental method, the video software method could be used just like the quantitative data of biomechanical method.

Purpose: The purpose of this study was to explore and describe the factors related to new nurses' organizational socialization (OS) process and to find out the strategic information for successful organizational socialization. Methods: The qualitative data were gathered from three focus group discussions with 13 new nurses and 5 experienced nurses. All interviews were recorded and transcribed. The transcript analyzed according to qualitative content analysis processes. Results: The factors related to new nurses' OS derived from new nurses' focus groups were 'burdens related to the characteristics of nursing duties', 'emotional and psychological characteristics' and 'facilitating factors to OS'. Two factors at the forepart were interfering factors to new nurses' OS. The factors related to new nurses' OS derived from experienced nurses' focus group classified to 'facilitating factors to OS', 'interfering factors to OS' and 'supports to facilitate new nurses' OS process'. Conclusion: The findings of the study revealed the facilitating and interfering factors to organizational socialization of new nurses. The main factors to interfere new nurses' OS were individual factors such as professional incompetency and psychological characteristics. On the other hand, Interactional factors within the organization were important to facilitate new nurses' OS. The findings can be applied for developing a special program to help new nurses adjust to the nursing organization successfully.

Two-level factorial designs are popular in industry due to their simplicity, efficiency, graphical interpretation, and flexibility in sequential experimentation. However, experimenters are often frustrated when they have factors with more than two levels. There have been some works on design of experiments with two- and four-level factors, which mostly deal with qualitative four-level factors. This paper discusses differences between qualitative and quantitative four-level factors. Optimal designs are provided for some designs with four-level quantitative and two-level factors.

The problem of system reliability is very important issue in the digitalized nuclear power plant, because the failure of its system brings about extravagant economic loss, environment destruction, and fatal damage of human. Therefore the purpose of this study has developed the reliability evaluation model through the scoring model by the quantitative and qualitative factors in order to justify the evaluation considering the advanced safety factors in the Advanced Pressurized water Reactor 1400MWe(APR 1400MWe) under uncertainty. Especially, the qualitative factors considering the human, information control, and quality factors for the systematic and rational justification have been closely analyzed. The proposed model can be simply applied in real fields in order to minimize the industrial accidents in the digitalized nuclear power plant.

This study was carried out to offer the basic methodology of the system and model to objectively assess the natural ecosystem for environmentally friendly land conservation and present the alternative plan on establishing the environmental policy. The results of this study were as follows. We selected four assessment factors associated with biotic, abiotic, qualitative, and functional factors. Also, there were extracted fifty-six indicators including density, total nitrogen, hemeroby degree, and goods production. The assessment factor showed that biotic one was very important. The importance of indicators were analyzed that rare and endangered plant was important in biotic factor, in case of abiotic, qualitative, and functional factors, organic matter, landscape diversity, and conservation of ecosystem were greatly important. The results of factor analysis on the characteristics of indicators, classified biotic factor into six factors including a structural one, abiotic factor as a soil and physical one, qualitative factor as five ones including hierarchical one, and functional factor as public and conservational one. In the results of analysis on assessment model, R-square of biotic factor was 51.7%, those of abiotic, qualitative, and functional one were each 58.4%, 44.2%, and 39.3%, and statistical problem was no existence. In future, to develop the assessement model and methodology of sustainable natural ecosystem, we will have to achieve the integrated model and grouping by assessment factor.
