  • The task for chromosome analysis and diagnosis by experienced cytogenetists are being concerned as repetitive, time consuming job and expensive. For that reason, intelligent agent based on chromosome knowledge base has been established to be able to analyze chromosomes and obtain necessary advises from the knowledge base instead of human experts. That is to say, knowledge base by IF THEN production rule was implemented to a knowledge domain with normal and abnormal chromosomes, and then the inference results by knowledge base could enter the inference data into the database. Experimental data were composed of normal chromosomes of 2,736 patients 'cases and abnormal chromosomes of 259 patients' cases that have been obtained from GTG-banding metaphase peripheral blood and amniotic fluid samples. The completed intelligent agent for chromosome knowledge base provides variously morphological information by analysis of normal or abnormal chromosomes and it also has the advantage of being able to consult with user on chromosome analysis and diagnosis.

  • Recently, knowledge management(KM) has attracted increasing attention from academicians and practitioners alike. Amongst others, technological knowledge(TK) is considered principal asset of KM and R,&D organization of private firms selves as primary actor of KM. It is also noted that the notion of sectoral pattern of innovation highlights idiosyncratic differences across industrial sectors in terms of TK management. That is, knowledge contents, knowledge generation and How pattern are considerably different among industries. This paper first analyzes the correlation between structural of R&D organization and industrial(sectoral) type to identify the dominant structure of R&D organization for each industry. Second, sector-specific architectures of TK management system are proposed. According to structural characteristic of R&D-organization type, test-practice forms of TK management system are suggested in terms of such factors as knowledge contents(technology information), knowledge generation activities, and knowledge storage/retrieval modes.

  • The increasing complexity of modem products requires the effective management of design knowledge, which partly resides in the product itself on the one hand. On the other hand, a lot of knowledge is gathered and/or generated during the design process, but disappears as the design project concludes. This paper describes a knowledge representation method to accommodate the implicit design knowledge. The method is based on the FBS(Function-Behavior-Structure) model and extends the object ontology with constraint entity. An example to represent the injection mold design knowledge is given to show its applicability.

  • Recently, knowledge transfer has been recognized as one of the major factors for success of IT projects but little investigated in Information Systems research. IT project, which needs collaboration between organization's IT project team and external partner, is an critical source for a firm to acquire external knowledge and to achieve its competitive advantage. Based on this recognition on knowledge transfer under IT project, we investigate a mediation role of knowledge transfer to IT project performance after identifying its antecedents such as project team capabilities and partner capabilities. The research model is tested by analyzing 161 sample data gathered from firms' employees who have participated IT projects within last two years. The results reveal that knowledge transfer has full-mediation effect between its antecedents and IT project performance. Moreover, project team capabilities have more impacts on knowledge transfer than partner capabilities do.

  • A framework for knowledge management system has been explored which enables the semantic search of knowledge on the web. Knowledge representation by RDF and RDF schema enables machine cognition of knowledge documents. Dublin core was adopted for structured metadata representation. Thereby, it enables the CBR and rule based reasoning for intelligent knowledge retrieval. Grafting of the WFMS technique unto the KMS facilitates the effective utilization of process knowledge and creation of new knowledge.

  • Purpose: This study was conducted to verify the effectiveness of a cost management education program, focusing on the differences between a web-based group and a mobile-based group. Method: This was a quasi-experimental study using a two-group pretest-posttest design. Participants were 74 nurses in a web-based group and 69 nurses in a mobile-based group. Data were collected between January 2 and February 10. The cost management education program was configured such that the participants studied eight modules over four weeks. The after-program post-test was conducted for one week. Results: Both the web-based group and the mobile-based group showed significantly higher values for cost management knowledge (S=5.98, p<.001 and S=2.76, p=.006, respectively). The web-based group had statistically significantly higher values for cost management knowledge (S=4,461.50, p<.001) than the mobile group. Conclusion: The cost management education program showed improvement in knowledge in both the web-based and mobile-based groups; however, the web-based approach was more effective for nurses. A cost management education program which can be implemented effectively across all range of nurses is recommended.

  • 이 연구는 과학 학습을 증진시키는데 필요한 교사 지식에 대한 학생들의 인식을 분석함으로써 과학 교사 효과성 요인을 조사하였다. 선행 연구를 통해 규명된 기초적인 교사 지식의 요소들은 탐색적 요인 분석(EFA)에 의해 확인되었으며, EFA 결과를 토대로 구조방정식 모델을 활용하여 확인적 요인 분석(CFA)을 실시하였다. 또한, 규명된 교사 효과성 요인에 대한 학생들의 인식을 성별 및 학업 성취 수준별로 차이를 분석하였다. 탐색적 요인 분석 결과, 과학 교사 효과성 요인으로 5개 요인(실체론적 지식, 구문론적 지식, 교육과정 지식, 학생 이해지식, 교수 전략 지식, 학생 평가 지식)을 확인하였으며, 5개 요인들을 다시 두 개의 교사 지식 범주(SMK와 PCK)로 분류하였다. 확인적 요인 분석 결과 실체론적 지식과 구문론적 지식, 학생이해 지식과 교수전략 지식 간에 각각 높은 상관을 나타내었다. 과학 교사 효과성 요인 중 학생들은 실체론적 지식을 가장 중요한 요인으로 인식하였으며, 학생평가 지식을 가장 덜 중요한 요인으로 인식하고 있었다. 또한 과학교사 효과성 요인에 대해 성별 및 성취수준에 따라 상당한 인식의 차이를 나타내었다. 이러한 연구 결과를 바탕으로, 효과적인 과학 수업실행을 위해서 SMK와 PCK가 정합적으로 통합될 필요가 있음을 제안하였다. 이 연구는 과학 교사 전문성 계발과 예비 과학 교사 양성 프로그램 개선을 위한 시사점을 제공한다.

  • The capitalization of know-how, knowledge management, and the control of the constantly growing information mass has become the new strategic challenge for organizations that aim to capture the entire wealth of knowledge (tacit and explicit). Thus, knowledge mapping is a means of (cognitive) navigation to access the resources of the strategic heritage knowledge of an organization. In this paper, we present a new mapping approach based on the Boolean modeling of critical domain knowledge and on the use of different data sources via the data mining technique in order to improve the process of acquiring knowledge explicitly. To evaluate our approach, we have initiated a process of mapping that is guided by machine learning that is artificially operated in the following two stages: data mining and automatic mapping. Data mining is be initially run from an induction of Boolean case studies (explicit). The mapping rules are then used to automatically improve the Boolean model of the mapping of critical knowledge.

  • High-tech industries in Taiwan exist in an environment with diverse product requirements and intense cost reduction and information integration stress. They must develop new operational directions to increase industry competitiveness. Therefore, Taiwan's high-tech industries must continue R&D and creativity, establish knowledge sharing mechanisms and improve new product development (NPD) performance. This research analyzed and explored the influences of knowledge management (KM) and knowledge sharing mechanisms introduced by Taiwan's high-tech industries on new product development performance. The relationship between knowledge management capabilities and NPD performance is studied. This research considers the intervening industry and corporate position variables. Taiwan's high-tech industries have gradually entered the era of IT region integration and application with competitive advantage creation based upon core techniques. The in-depth study of knowledge management and knowledge sharing introduced by the high-tech industry revealed double meanings in academic and practical applications. The research results showed the following: (1) the stronger the knowledge management capabilities of Taiwan's high-tech industries, the more significant the NPD performance. (2) The better the knowledge sharing mechanism in Taiwan's high-tech industries, the more significant the NPD performance. (3) Corporate scale is not necessarily the critical factor in NPD success and the influence of corporate scale on NPD performance did not show significant differences. (4) The stronger the degree of leading corporate techniques, the more significant the NPD performance.
