Quality information is known to have the characteristic of continuous distribution in many manufacturing processes. It is difficult to describe the process condition by classifying the distribution into discrete ranges which is based on the set concept. Fuzzy control chart has been developed for the control of linguistic data but it still utilizes the dichotomous notion of classical set theory. In this paper, the fuzzy sampling method is studied in order to manage the ambiguous data properly and incorporated for generating fuzzy control chart. The method is based on the fuzzy set concept and considered to be appropriate for the realization of a complete fuzzy control chart. The fuzzy control chart was compared with the conventional generalized p-chart in the sensitivity for quality distribution and robustiness against the noise. The fuzzy control chart with the fuzzy sampling method showed better characteristics.

This paper describes the role of TQC and its present issues as a management tool, especially in regard of Korean firm's environment. The author, participating in TQC activity for himself, stresses that the introduction and driving programs of TQC activity must include such plans as policy control, reorganization, training, standardization, quality assurance, QC circle activity, office management and auditing. The keypoints and problems in performing these plans are reviewed. And as the future hopeful direction of TQC activity, he remarks that a true recognition of quality control as a management tool in "total" concept and the adoption of industry - wide quality control policy.

Companies had to be more intelligent in order to survive in the rapidly changing environments. We need to make a decision to build the Information System to support the managers in their decision making. That is the reason many companies are tend to have Business Intelligence Systems. But, how can we know the new system would be better than the old system in making us intelligent? The answer is we can do it with the concept of Intelligence Density. In this study, Intelligence Density concept will be introduced, and the way how it can be applied to the information system will be presented. I think Intelligence Density should be studied more to help managers make right decisions for the DSS implementation.

An alternative estimator for dose equivalent was derived. The original LET distribution concept was transformed into a charged particle fluence spectrum concept along with the definition of an average quality factor named slowing-down averaged quality factor by adopting the continuous slowing down approximation. With the alternative estimator, the dose equivalent delivered into a receptor located in a given radiation field can be directly and conveniently estimated in a Monte Carlo procedure. The slowing-down averaged quality factors for the energy range below 10 MeV were evaluated and tabulated for the charged particles which may be generated from the interactions of neutron with the nuclei composing soft tissue.

As Web services cover more and more IT area and the number of their implementation cases increase rapidly, most associates have begun to consider the quality of Web services. They require the framework that helps to evaluate and measure the quality of Web services. OASIS WSQM(Web Services Quality Model) technical committee already published Web Services Quality Model specification version 2.0 in 2006. However, it has been described in conceptually. That is, it contains the model view, classification of quality factors, some activities and associates. So, we need Web services quality description language (WSQDL) shaped in XML. To describe WSQDL schema, we need a new paradigm to represent the Web services quality factors consistently and interoperably. For this we provide the new concept of quality chain in this paper.

Purpose: Ego-integrity in Erikson's stage theory is used frequently among health team members related to the care of the elderly and has specific meanings within the context of quality of life in later life. However, the concept of ego-integrity in the elderly has not been well articulated in the literature. This study was conducted clarify and conceptualize the phenomena of ego-integrity in the elderly. Method: A Hybrid Model of concept development was applied to develop a concept of ego-integrity, which included a field study carried out in Seoul, South Korea using in-depth interviews with old adults who were admitted as a right person for research subject according to attributes of ego-integrity analysed in the theoretical phase. Results: The concept of ego-integrity emerged as a complex phenomenon having meanings in several different dimensions which encompassed several attributes. Conclusions: Ego-integrity is a concept having needs that should be treated in a specific way and it is possible to enrich the meaning and methods to manage ego-integrity in nursing interventions for promoting quality of life so that its application may have effects that have positive impacts on the elderly's well being.

Purpose: This study was done to analyze and clarify the concept of empathy in nursing. Methods: Using the concept analysis framework of Walker & Avant 68 articles about empathy were selected for this study. Results: Defining attributes of empathy included recognizing others' perspective and thought, understanding others' emotion, and communicating with them. The antecedents of empathy included contact with patients, respect and trust for patients, a certain level of cognitive ability, and communication skills. Consequences of empathy were increasing patient self-understanding, self-awareness as a therapeutic subject and improving quality of nursing. The concept was clarified through presentation of model, borderline, related, and contrary cases. Conclusion: The results of this study are meaningful in that the concept and attributes of empathy are explored in the area of nursing. Also, based on results of this study, development of standardized tools to measure patient-perceived empathy and measure the three attributes of empathy is recommended as well as the development of educational programs to enhance empathy.

Purpose: The purpose of this study was to identify attributes of the concept of spiritual care. Method: Walker & Avant's concept analysis framework was employed to review the clinical guidelines, nursing text books, and nursing research articles which were related to spiritual care and published from 1985 to 2005. Result: The attributes of the concept of spiritual care were a three stage process such as spiritual assessment, spiritual intervention, and spiritual evaluation. Spiritual care included three dimensions of relationships such as transpersonal, interpersonal, and intrapersonal. The quality of spiritual care was dependent upon characteristics of care-givers such as perception and knowledge of spiritual care, and the clinical environment. The antecedents of spiritual care was spiritual needs due to the prompt events. The consequence of spiritual care was spiritual well-being. Conclusion: This concept analysis of spiritual care contributed to promote performance of spiritual care in clinical fields by removing conceptual ambiguity and confirming the true meaning of spiritual care.

Purpose: The purpose of this study was to analyze the effects of professional self-concept and self-efficacy on job satisfaction and to identify the relationship among them in clinical nurses. Methods: The subjects were nurses who were working for three general hospitals in Seoul and Gangwon province for two month starting in July 2007. Three questionnaires were used. One was job satisfaction and the others were professional self-concept and self-efficacy. The data were analyzed by SPSS/PC ver 12.0. Results: The mean score of job satisfaction was 2.99 (range: 1-5). The mean score of professional self-concept and self-efficacy were 2.71(range: 1-4) and 3.49(range: 1-5), respectively. Differences of job satisfaction were significantly related to differences in age, marital status, level of education, clinical career, annual salary, and shift pattern. With respect to job satisfaction, the pearson correlation coefficients were .43 for professional self-concept and .29 for self-efficacy. The multiple regression revealed that the significant predictor of job satisfaction was professional self-concept. Conclusion: This study showed that a strong professional self-concept improves job satisfaction, so professional self-concept improvement programs should be developed to improve job satisfaction and to improve the quality of nursing.

Since the mid 1980s, the concept of logistics has become more important to the enterprises in strategic sense because it had aggrandized itself to more comprehensive and integrative concept. Therefore study on the service organization of the logistics system for customer’s satisfaction from the management’s point has been focused as one of the major subject in order to improve the logistics quality which would ultimately increase the value of logistics service. This study has been focused on what the port logistics functions and the factors of the port logistics quality are those Korean port managers acknowledge as important factor. And examins these port logistics quality levels and the port logistics value (port productivity, service results) obtained by the results of these activities while reviewing the relation of the custom value which the port managers evaluate in order to evaluate and promote the competitiveness of the Korean port. According to the study results the port logistics function which the Pusan Container Terminal managers recognized as important were customer service management the flexibility of the port facilities and curtailment of the original operation cost of the port. It also indicated that the managers recognized the importance of the customer-oriented terminal management as it showed a close relationship with the port quality level.
