Lately, knowledge-based society comes, it is important for enterprises to creatively utilize knowledge of technology for technological innovation. So, Technological innovation capacity of enterprises is important factor of business success. To improve technological innovation capacity, enterprises should well utilize their internal knowledges and external knowledges which come from technological diffusion. To well utilize external knowledges of enterprises they should well understand external knowledge flow. Especially knowledge flow also occurs frequently between nations, understanding of knowledge flow which occurs between nations is important to improve nation`s technological innovation capacity. So this paper presents comparison of technological innovation capacity and knowledge diffusion flow between nations.

Company perform a lot process to produce products. If company try to satisfy for customer and improve technological competition, they must be changed to new system. As a result, we developed knowledge based smart search system and customized it to PDM system on commercial use. In this smart search system, wherever process designer can seek to result quickly. This will be upgraded for be applied to some company.

Data mining, which is also referred to as knowledge discovery in database, means a process of nontrivial extraction of implicit, previously unknown and potentially useful information (such as knowledge rules, constraints, regularities) from data in databases. The discovered knowledge can be applied to information management, decision making, and many other applications. In this paper, a new data mining problem, discovering sequential patterns, is proposed which is to find all sequential patterns using sampling method. Recognizing that the quantity of database is growing exponentially and transaction database is frequently updated, sampling method is a fast algorithm reducing time and cost while extracting the trend of customer behavior. This method analyzes the fraction of database but can in general lead to results of a very high degree of accuracy. The relaxation factor, as well as the sample size, can be properly adjusted so as to improve the result accuracy while minimizing the corresponding execution time. The superiority of the proposed algorithm will be shown through analyzing accuracy and efficiency by comparing with Apriori All algorithm.

플랜트를 대상으로 하는 엔지니어링의 업무영역은 플랜트의 기획, 설계, 시공, 운영 및 폐기에 이르는 생애주기에 걸친 생산성과 성능 및 품질에 직접적인 영향을 미치는 복합적인 기술분야이다. 이때 발생하는 다양한 유형의 데이터를 활용하여 의사결정을 활용하는 것은 후속 과정뿐만 아니라 생애주기 관점에서도 중요한 영향을 미치고 있다. 하지만 이러한 데이터를 통합적으로 관리하고 분석할 수 있는 시스템은 부족하다. 본 논문에서는 플랜트 생애주기에서 발생하는 데이터를 관리하고 활용할 수 있는 지식베이스 기반 플랜트 엔지니어링 분석 플랫폼을 개발하였다. 플랫폼에서는 기수집된 엔지니어링 데이터를 전처리한 지식베이스를 제공하고, 이를 레퍼런스 데이터로 AI 모델에 활용하도록 분석 기능과 시각화를 제공한다. 사용자는 플랫폼을 통한 선행기술과 축적된 지식의 활용을 통해 데이터 분석을 진행하고 시각화를 의사결정에 활용해 경험에만 의존하던 공사를 합리적이고 체계적으로 관리할 수 있다.

The development of a practical technology intelligence system requires a knowledge base that structures the core information and its relationship distilled from large volumes of technical data. Previous studies have mainly focused on the methodological approaches for technology opportunities, while little attention has been paid to constructing a practical knowledge base. Therefore, this study proposes a procedure to construct a function-based knowledge base for technology intelligence. We define the product-function-technology relationship and subsequently present the detailed steps for the knowledge base construction. The knowledge base, which is constructed analyzing 1110582 patents between 2009 and 2013 from the United States Patent and Trademark Office database, contains the functional knowledge of products and technologies and the relationship between products and technologies. This study is the first attempt to develop a large-scale knowledge base using the concept of function and has the ability to serve as a basis not only for furthering technology opportunity analysis methods but also for developing practical technology intelligence systems.

A number of practices for sharing knowledge has been recommended in the literature. These practices, however, are considered to be applicable, universally. This assumption is challenged by this paper which empirically explores the relationship between national culture and knowledge sharing practices in the context of procuring educational buildings in Saudi Arabia. The paper reports on a research study with the aim to identify whether national culture dimensions could be significant variables that impact upon staff preferences in relation to project knowledge sharing practices. The paper critically reviews the literature to identify appropriate measures for knowledge sharing practices. It explores the means by which public sectors professional exchange project knowledge; evaluates policies and level of technical support needed to facilitate knowledge sharing, then proceeds to how employees perceive the benefits they will gain by practicing project knowledge sharing, and their role in this process. The paper tests the relationships among the research constructs based on data collected from 115 project managers responsible for the procurement of educational buildings in Saudi Arabia. The paper provides empirical evidence that the national culture has a significant influence on staff preferences. In light of the research findings the paper concludes with practical recommendations for project knowledge sharing practices that are in line with staff preferences and their cultural orientation. The recommendations should facilitate a more effective application of knowledge sharing practices.

최근 국내에서도 지식경영과 관련한 연구와 실례가 다수 발표되고 있다. 그러나 지식경영의 이론적 배경을 완전히 이해하지 못한다면, 이를 지식창출(Knowledge creation)을 지원하는 경영도구(Managerial application)로 이해하기 보다는 정보를 관리하는 또 다른 방법으로 오인하기 쉽다. 이에 본 논문에서는 지식경영이 최근 주요 경영도구로 회자되고 있는 배경을 당대의 경영환경 및 과학철학(Philosophy of Science)을 중심으로 살펴본다. 이후 데이터(Data) 및 정보(Information)와 비교되는 지식의 특성을 고려하여 이를 창출하거나 이의 흐름(Flow)을 활성화(Facilitating)하기 위한 여러 가지 방안 중 연성정보시스템 방법론(Soft Systems Methodology)을 고찰해 본다. 연성정보시스템 방법이 건설경영(Construction Management)관련 대학교육과 실무에 어떻게 접목될 수 있는지에 관한 논의로 결론을 맺는다.

의료 시스템이 개발되면 시스템이 사용하는 knowledge source의 신뢰도가 시스템의 수행능력에 큰 영향을 미치게 되므로, knowledge source의 신뢰도를 검증해야한다. 본 논문은 의료 시스템 CLINAID의 knowledge source의 신뢰성 조사에 대한 연구의 방법과 결과를 발표하였다. 그 방법으로는 CLINAID에 사용된 Cardiovascular body system 데이터에 fuzzy relational method를 적용하여 구조적 분석을 통해 만들어진 인공의 syndrome을 knowledge base에 저장되어있는 의료 전문가의 syndrome과 비교하였다. 7 가지 fuzzy implication operator를 사용하여 거의 비슷한 결과들을 산출해 냈으며, 그 결과들이 전문가가 제공한 syndrome과 거의 일치하였다.

This paper reviewed the two proposed hypotheses. The first hypothesis is to test the relationship between knowledge management and incremental innovation, and the second hypothesis is to test the moderating effect of firm-size on that relationship. Data were gathered from 434 employees in service industry, and multiple regression analysis was used to test two proposed hypotheses. In the first hypothesis, it was appeared that knowledge acquisition and knowledge transfer have positive effects on all incremental innovation factors (process innovation, operation innovation, service innovation). In the second hypothesis, it was appeared that firm-size has an positive interaction effect on incremental innovation in knowledge transfer, but not in knowledge acquisition. It means that knowledge transfer has more positive effect on incremental innovation in large firm-size than in small firm-size.

Existing CAD systems have configured geometry data and it is necessary to extend the configured geometry into a knowledge-based system. An intelligent CAD system emerged to provide such a knowledge-based system. However the intelligent CAD system has a limited product model to represent various knowledge models. This paper presents a model, called extended intelligent CAD model, which can extend the product model of the intelligent CAD system into further detailed knowledge model. The extended intelligent CAD model includes a whole design process knowledge and an efficiency of the model has been verified via a knowledge based wiper design system. The model can improve the functionality and efficiency of the existing CAD systems.
