지식정보사회의 출현으로 기업은 지식정보에 대한 중요성을 인식하고 지식을 창출, 이전 및 활용하는 지식경영에 많은 관심을 갖고 있다. 특히 중소기업은 대기업에 비해 자본과 전문인력이 부족하기 때문에 지식경영의 활성화를 통해 변화에 대응하려는 노력이 요구된다. 이에 본 연구에서는 중소기업의 관리시스템과 지식경영활동의 관계를 실증분석하며, 그러한 관계에서 조직구조의 조절효과를 살펴보고자 한다. 실증 분석을 위한 자료수집은 강원 영서지역에 입지한 227개 중소기업에 대한 설문의 배부 및 회수를 통해 이루어졌다. 관리시스템이 지식경영에 미치는 효과 및 조직구조로서 분권화와 공식화의 조절효과를 분석한 결과, 최고경영층지원과 교육훈련은 지식획득과 지식이전에 긍정적 영향을 미치는 것으로 나타났다. 그리고 관리시스템(최고경영층지원, 보상체계, 교육훈련)과 지식경영의 관계에서 분권화와 공식화의 조절효과에 대한 분석결과 분권화는 교육훈련이 지식이전에 미치는 긍정적 효과를 증가시키는 것으로 나타났다. 공식화는 최고경영층지원과 보상체계가 지식획득에 미치는 긍정적 효과를 감소시키며, 보상체계가 지식이전에 미치는 긍정적 효과도 감소시키는 것으로 나타났다. 최고경영층지원과 교육훈련이 지식획득과 지식이전에 긍정적 영향을 미친다는 점에서 최고경영층은 구성원들의 제안이나 아이디어 창출을 장려하고, 수평적 의사소통채널을 활성화하여 생성된 지식과 정보가 구성원들에게 폭넓게 전파되도록 하는 것이 필요하다. 그리고 교육훈련을 업무상 아이디어 창출과 관련된 기법을 습득하도록 하며, 교육훈련 이후의 전파교육을 통해 지식생성과 지식이전을 촉진하도록 설계할 필요가 있다. 분권화는 관리시스템이 지식경영활동에 미치는 긍정적 효과를 촉진하는데 반해 공식화는 긍정적 효과를 감소시키는 것으로 나타났다. 따라서 권한위임과 재량권 위양을 통한 분권화를 지향하고, 규정과 절차에 따르기 보다는 조직간소화를 추진함이 바람직하다.

This study has investigated the effects of promoting and inhibiting factors on information sharing between buyers and sellers in Korean distribution industry. Based on intensive literature reviews, eight promoting factors(satisfaction, relational norms, trust, commitment, fairness, formalization, participation, transaction specific investment) and five inhibiting factors(opportunism, environmental uncertainty, conflict, concentration, monitoring) were included in the research model. For the purpose of empirical testing, 320 respondents of retailers in Korea were surveyed and the analysis utilizing structural equation model indicated that satisfaction, relational norms, trust, commitment, fairness, formalization, and participation had positive effects on information sharing. And concentration and monitoring had negative effects on it. However transaction specific investment, opportunism, conflict, and environmental uncertainty had no significant effects.

Purpose: This study was designed to measure the level of professional autonomy regarding physical therapists and to determine the association of organizational and occupational characteristics of the profession with its professional autonomy. Methods: We utilized a structured questionnaire survey of physical therapists (280 persons) in Jeju province. Data were collected from June 25 to July 14 in 2012. An additional 173 (63%) of them were used in the final analysis. Using PASW 18.0, descriptive and Hierarchical Linear Model were performed. Results: Regression analysis Result of Factors influencing Physiotherapist Professionalism, refresher training course (t=4.27), formalization (t=3.13), task significance (t=3.39), and autonomy (t=4.17) had a positive effect. Autonomy (${\beta}$=0.33) and formalization (${\beta}$=0.33) exerted the greatest influence. Conclusion: The survey regarding organizational and job characteristics showeds that occupational reeducation, formalization, and self- regulation constitute a positive part of what the professional autonomy is to be upheld. Results of the survey imply that in order to establish professional autonomy for the profession of physical therapist, the organization must make various efforts to beef up the exclusive knowledge and technology, and professional norms of the occupation that are considered essential for specific problem solving.

The diagrammatic language for pathways is widely used for representing systems knowledge as a network of causal relations. Biologists infer and hypothesize with pathways to design experiments and verify models, and to identify potential drug targets. Although there have been many approaches to formalize pathways to simulate a system, reasoning with incomplete and high level knowledge has not been possible. We present a qualitative formalization of a pathway language with incomplete causal descriptions and its translation into propositional temporal logic to automate the reasoning process. Such automation accelerates the identification of drug targets in pathways.

The verification phase of knowledge base is an important part for developing reliable expert systems, especially in nuclear industry. Although several strategies or tools have been developed to perform potential ewer checking, they often neglect the reliability of verification methods. Because a Petri net provides a uniform mathematical formalization of knowledge base, it has been employed for knowledge base verification. In this work, we devise and suggest an automated tool, called COKEP (Checker Of Knowledge base using Extended Petri net), for detecting incorrectness, inconsistency, and incompleteness in a knowledge base. The scope of the verification problem is expanded to chained errors, unlike previous studies that assumed error incidence to be limited to rule pairs only. In addition, we consider certainty factor in checking, because most of knowledge bases have certainty factors.

Knowledge acquisition is the process that extracts the required knowledge from available sources, such as experts, textbooks and databases, for incorporation into a knowledge-based system. Knowledge acquisition is described as the first step in building expert systems and a major bottleneck in the efficient development and application of effective knowledge based expert systems. One cause of the problem is that the process of human reasoning we need to understand for knowledge-based system development is not available for direct observation. Moreover, the expertise of interest is typically not reportable due to the compilation of knowledge which results from extensive practice in a domain of problem solving activity. This is also a problem of modeling knowledge, which has been described as not a problem of accessing and translating what is known, but the familiar scientific and engineering problem of formalizing models for the first time. And this formalization process is especially difficult for knowledge engineers who are often faced with the difficult task of creating a knowledge model of a domain unfamiliar to them. In this paper, we propose an automated knowledge acquisition tool which is based on an implementation of the Inferential Modeling Technique. The Inferential Modeling Technique is derived from the Inferential Model which is a domain-independent categorization of knowledge types and inferences ［Chan 1992］. The model can serve as a template of the types of knowledge in a knowledge model of any domain.

컴퓨터를 활용한 지식과 정보 처리를 위해 온톨로지를 구축하고 활용하기 위한 연구가 이루어지고 있다. 그러나 현재까지의 온톨로지 개발 방법 및 온톨로지 구축 도구는 온톨로지 개발 목적에 따라 제한적인 부분에서 연구되어 사용되고 있다. 그러므로 개발하려는 온톨로지 특성에 따른 적절한 온톨로지 구축 프로세스와 도구가 필요하다. 본 논문에서는 특정 분야의 비전문가가 언어 자원으로부터 지식을 개념화하고, 개념을 형식화하여 온톨로지를 구축할 수 있는 온톨로지 구축 프로세스(OntoProcess)를 제안한다. 그리고 다수의 온톨로지 구축자가 동시에 온톨로지 구축 작업을 행할 경우 i)지식의 개념화 과정에서 동일한 개념을 중복 정의하거나 ii)개념의 형식화 과정에서 형식언어와 포구사용법의 이해 부족으로 인해 온톨로지 구축 능률이 저하되는 문제가 발생할 수 있다. 이런 문제를 해결하기 위해 메타 온톨로지를 이용한 다중 온톨로지 구축 프로세스(OntoProcess)를 제안한다. 제안한 프로세스에 기반한 온톨로지 구축 시스템 (OntoProcess)을 개발하고, 실제 온톨로지 구축 실험을 통하여 제안한 프로세스와 시스템의 효율성을 확인한다. 그리고 온톨로지 구축 과정에서 발견된 문제점 및 이에 대한 해결 방안을 제시한다.

Utilizing construction knowledge and experiences in design phase can reduce change orders and improve productivity in construction phase. To do so, information must be made available to the design team in time. Current approaches for effective utilization of constructability knowledge, however, only focus on the formalization of constructability knowledge such as a checklist, which lacks the consideration of the appropriate use at the proper point in time. The inadequate use of constructability knowledge can result in unnecessary reworks. To deal with this problem, the design team needs to know what constructability knowledge is required for specific design activities in the design process. This paper presents a constructability implementation model using the dependency structure matrix (DSM) that focuses on information flows between design activities and constructability knowledge. For this objective, design activities in the design process are modeled in a matrix form based on their dependency. Then, constructability knowledge, which needs to be considered in the design stage, is mapped into activities and incorporated into the matrix, creating Constructability-DSM (C-DSM). Next, the partitioning algorithm is applied to C-DSM for optimal information flow. The Partitioned C-DSM is then analyzed based on the relationship between activities. Finally, the optimal utilization of construction knowledge in the design process is determined by identifying what constructability knowledge is required for each design activity, and how and when it is reflected to design for constructability. Thus, this research can help provide robust control actions to reduce unnecessary iterative cycles in design process for efficient constructability implementation.
