  • The discovery of tacit knowledge from domain experts is one of the most exciting challenges in today\`s knowledge management. The nature of decision knowledge in determining the quality a firm\`s short-term liquidity is full of abstraction, ambiguity, and incompleteness, and presents a typical tacit knowledge extraction problem. In dealing with knowledge discovery of this nature, we propose a scheme that integrates both knowledge elicitation and knowledge discovery in the knowledge engineering processes. The knowledge elicitation component applies the Verbal Protocol Analysis to establish industrial cases as the basic knowledge data set. The knowledge discovery component then applies fuzzy clustering to the data set to build a fuzzy knowledge based system, which consists of a set of fuzzy rules representing the decision knowledge, and membership functions of each decision factor for verifying linguistic expression in the rules. The experimental results confirm that the proposed scheme can effectively discover the expert\`s tacit knowledge, and works as a feedback mechanism for human experts to fine-tune the conversion processes of converting tacit knowledge into implicit knowledge.

  • As environmental protection is becoming more and more important, green production has become a key issue for almost every manufacturer and will determine a manufacturer can be sustainable in the long term. Therefore a performance evaluation system for green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. While the works on the evaluation and/or selection of suppliers are abundant, those that concern environmental issues are rather limited. The objective of this study is to construct a combined model based on fuzzy analytic hierarchy process (FAHP) and balanced scorecard (ESC) for evaluating green suppliers in the manufacturing industry. The ESC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is finally constructed to facilitate the solving process. With the proposed model, manufacturers can have a better understanding of the capabilities that a green supplier must possess and can evaluate and select the most suitable green supplier for cooperation.

  • Until now, the meaning of terms in most of thesauri has been indirectly presented through relationships and scope notes. However, as thesaurus has been expanded quantitatively, it has become difficult to understand meaning of terms clearly using those relationships and scope notes. Though some thesauri take the form of 'thesaurus dictionary' in order to present the meaning of descriptors, the contents and forms of provided definitions are not satisfying. As standardized definitions of terms integrate into thesaurus on the basis of necessity of definitions providing meaning of terms, this study has shown a possibility for further development of thesaurus.

  • This article aims to examine the concept and historical background of Applied Theatre and its major characteristics as a newly emerging theatrical practice in recent years. With these aims, the article chronicles the history of how Applied Theatre has developed and formed as an overarching umbrella term that encompasses different theatrical praxis. Given the ambiguity and confusion of this practice, the article argues the importance of recognizing the Applied Theatre's shifting paradigm of subject and object, a crucial element in understanding the practice. Further discussed is the exploration of 'community' in regards to comparing the similarities and differences among Applied Theatre, Community Theatre, and Community-based Performance. The article concludes that the essential comprehension of Applied Theatre's uniqueness comes from noticing and perceiving the paradigm shift that places participants and community as a subject of theatrical transaction rather than as an object, as traditional theatre has done so far.

  • The purpose of this study was to suggest an improvement proposal for colors in urban environment with special regard to the surface color and their situations of apartment buildings in Seoul. For this goal, 167 cases of different color types of apartment buildings were surveyed. And, the survey was performed in the view of color by areas, by localtion, by builder, by paint year, by built year, by appearance of building, and by surface texture to prove the influencing factors on the surface colors. These collected data analyzed and compared with the existing studies to find out the changing trend of colors. The results are as follows : 1) The use of neutral gray($26.4{\%}$) and warm color(YR, Y, GY; 56.4%) were dominant and the usage trend of higher 'value'(87.4%) and lower 'saturation'(73.0%) was obvious. Especially, the use of PB and P was noticeable. 2) In comparing the existing studies, the changing trend in the surface color pattern was found. That is, neutral gray was used dominantly in 1970's, warm color(YR, Y)in the middle of 1980's. In the end of 1980's, warm color were also used dominantly same as before and GY, PB, P were used noticeably with some rising tendency of higher 'value' and lower 'saturation' was obvious. 3) The results of analysis by localtion shows that the different color groups might exist in Seoul city. Neutral gray and YR were dominant in zone I. Warm colors(YR, Y, GY)were prevailed in zone II, III, IV. In zone V, many colors were evenly used. In zone VI, middle values at warm color were dominant. Progressively, these color groups with further study could be considered in the color management in urban environment possibly. 4) Surface color of apartment buildings were different from their builders. 5) Concerned with the painted year, the use of higher 'value' and lower 'saturation' was increased gradually with the change of times. 6) the analysis by the built year revealed that the 'value' of surface colors on the old buildings was lower than that of the new ones. 7) The 'value' of colors on the surface with texture was higher than that of the surface without texture. 8) In the combination of two colors, the use of 'value' with difference at the same 'hue' was found harmonions in many cases, but the 'saturation' in usage was included in the ambiguity (Moon & Spencer's term). The ambiguity in color harmony should be improved in the near future.

  • This study examined the effects of elderly care facility social workers' work environment (role conflict, role ambiguity, role overload, and adequacy of the reward system) and personal tendency (emotional empathy, cognitive empathy, external attribution, and internal attribution) on their burnout (emotional burnout, low personal achievement, and depersonalization about clients) and suggested strategies for preventing burnout in social workers at elderly care facilities. For this purpose, we conducted a questionnaire survey of social workers working at institutions designated as elderly long-term care facilities and collected a total of 312 questionnaires. According to the results of analyzing the data using a structural equation model, among the sub-factors of work environment, role ambiguity had a significant positive effect on low personal achievement and depersonalization about clients, role conflict on emotional burnout, and role overload on depersonalization about clients. Among the sub-factors of personal tendency, cognitive empathy and internal attribution had a significant negative effect on low personal achievement, and external attribution had a significant positive effect on emotional burnout and depersonalization about clients. This study is meaningful in that it illuminated social workers' burnout not only from the aspect of work environment but also from that of personal tendency.

  • The purpose of this study was to investigate the effects of the elderly long-term care workers' job stress on psychological burnout and organizational effectiveness and the moderating role of social support. For this study, data were collected from 290 long-term caregivers from 50 in-home visitation care facilities in Seoul using structured questionnaires. Collected data were analyzed using hierarchical regression techniques. Results showed that role three job stress variables had positive effects on caregivers' psychological burnout; that two job stress variables(role ambiguity and role conflict) and psycholigcal burnout had negaive effects on caregivers' job satisfaction whereas they had positive effects on caregivers' intent to leave; that workload negatively impacted caregivers' job satisfaction but no effect on their intent to leave; and that two social support variables played moderating roles in the relationship between job stress and psychological burnout and the relationship between job stress and organizational effectiveness.

The Meaning of Practice in Theory (이론(理論, Theoria)에 있어서의 실기의 의미)

  • What is 'Art Theory'? In the western sense, the term poses a vague ambiguity, and in the eastern, it is rather an abstract and metaphysical concept. As for etymology, theory is derived from theoria and theoria from theoros. It refers to an act of viewing or seeing, of course not in a metaphysical sense. Plato understood it as 'eide'. During the time of Plotinus, theoria encompassed gazing at every possible reality, and this gazing, that is theoria, is closely related to reality as aunit that theoriacan perceive. However, we tend to distinguish, as other scientists of dualism have done, studio art from theory since a pre-modern approach to art has been particularly tuned to studio practice, set apart from theory. Therefore, in studio classes, students are expected to learn the subject based on the foundational curriculum methods such as medium, genre, technique:, rather than bringing out their own interpretations and discussing theories. As a result, students have become artists, who are not able to understand their own art. Art professors who conduct class in studio are required to proceed with specific 'theories' as well as 'intellectual reflections'. In this respect, this thesis presents poiesis and an idea of 'acting out'. Although art history and aesthetic theory tend to view art as a finished product, actual art-making and related theories should not only be acknowledged as 'completion' (finition) but also be accompanied by theoretic interpretations of the act itself and process. Accordingly, it is to accept and appreciate art as finished result in view of current theory and aesthetics thus boils down to aisthesis. Likewise, poietics starts from a point where an artist is related to studio and examines the 'work process' that extends as far as to the exact end of work. Through the study of such relationship, it is possible that theory understands 'studio' and 'process', and an artist can grant an independent meaning to studio where s/he pours her/his heart out creating a work of art. Theory is a study on artistic discovery thus should be equipped with functions that can accommodate fortuity, imitation, thinking, culture, and surrounding.

  • This paper presents the first version of a Korean glossary of terms for structural developmental abnormalities in common laboratory animals, mainly rats, mice and rabbits. This is a translation of the glossary entitled Terminology and Developmental Abnormalities in Common Laboratory Mammals that was edited by the International Federation of Teratology Societies(IFTS) Committee on International Harmonization of Nomenclature in Developmental Toxicology. The purpose of the Korean glossary is to provide a common vocabulary that will reduce confusion and ambiguity in the description of developmental effects, particularly in submissions to regulatory agencies worldwide. The glossary contains a primary term or phrase, a definition of the abnormality, and notes, where appropriate. Selected synonyms or related terms, which reflect a similar or closely related concept, are noted. Non-preferred terms are indicated where their usage may be incorrect. Modifying terms used repeatedly in the glossary(e.g., absent, branched) are listed in Appendix A, and syndrome names are generally excluded from the glossary, but are listed separately in Appendix B. The glossary is organized into broad sections for external, visceral, and skeletal observations, then subdivided into regions, structures, or organs in a general overall head to tail sequence. Numbering is sequential, and not in any regional or hierarchical order, Uses and misuses of the glossary are discussed. Updates of the Korean glossary are planned based on the comments received.

  • Use of a passive bistatic radar (PBR) system in the surveillance or monitoring of an area has its advantages. For example, a PBR system is able to utilize any available signal of opportunity (for example, broadcasting, communication, or radio navigation signals) for the purposes of surveillance. With this in mind, there are potentially many research areas to be explored; in particular, the capability of signals from existing and future communication systems, such as 4G and 5G. Long-Term Evolution (LTE) is the world's most current communication system. Given this fact, this paper presents the latest feasibility studies and experimental results from using LTE signals in PBR applications. Details are provided about aspects such as signal characteristics, experimental configurations, and SNR studies. Six experimental scenarios are carried out to investigate the detection performance of our proposed system on ground-moving targets. The ability to detect is demonstrated through use of the cross-ambiguity function. The detection results suggest that LTE signals are suitable as a source signal for PBR.
