  • 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.

  • Currently, The budget expenditure for national R&D has been on the rise, and the quantitative performance in national R&D programs has been increasing accordingly. However, a growth of qualitative performance can not reach to an upward trend of quantitative performance. For a poor qualitative performance such as patent grades and technologies with low efficiency of technology transfer, the performance evaluation centered on "number of cases" is necessary to improve and start to introduce various "qualitative performance indicators". This paper focuses on "Triadic Patent Families" being measurable the overseas competitiveness of patent applied in major countries(the US, Europe and Japan). It analyzes the influencing factors to evaluate the quality of qualitative performance of R&D program. The result of this analysis shows a significant effect on the creating of triadic patent families within factors of R&D scale and project characteristics. This paper is significantly meaningful to expand insufficient triadic patent families to the target of interest rather than early study relatively, and to analyze the influencing factors of the creation of triadic patent families.

  • One of the main problems of today's ubiquitous computing systems is that they do not meet their quality requirements. Prior studies had investigated quality factors that were important to users regardless of use contexts. However, mobile computing services such as mobile data services (MDS) are fundamentally different from traditional information systems (IS) because it has been used in various life contexts. We conducted a qualitative study to identify important quality factors on various contexts in MDS. The results show that important quality factors in mobile computing services are differentiated from important quality factors in information systems.

  • 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.

  • 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.
