Recently, enterprise systems require the necessity of integration for data sharing and cooperation. As a methodology for integration, Service-Oriented Architecture for service integration and Master Data for integration of data, which is used for service, were appeared. This paper suggests a method that operates BP(Business Process) efficiently. We make XMDR(eXtended Meta Data Registry) as knowledge-repository to support the BP and construct data hubs to operate it. XMDR manages MDM(Master Data Management) to integrate the data, resolves heterogeneity between the data and provides relationship to the business efficiently. This is composed of MDR(Meta Data Registry), ontology and BR(Business Relations). MDR describes relationship between meta data to solve structured heterogeneity. Ontology describes semantic heterogeneity and relationship between data. BR describes relationship between tasks. XMDR data hub supports the management of master data and interaction of different process effectively.

Much research on ontology has been done during the last decade in order to represent knowledge and connect data semantically in AI and Semantic Web areas. However, ontologies might be represented and defined in different ways depending on knowledge and intention of users. It causes heterogeneity problem that the same concept can be differently expressed. This paper introduces a XOB (XMDR-based Ontology Builder) system based on XMDR to resolve the problem. XOB creates ontologies by reusing classes and relations defined in XMDR. XOB therefore is able to either solve or minimize the heterogeneity problem among ontologies. This paper introduces the conceptual model and overall architecture of the proposed system XOB. This paper defines the process, algorithm, ontology generation rule that is required to create ontologies by using concepts registered in XMDR. Our proposal supports higher standardization than the previous approaches, and it provides many advantages such as consistent concept usage, easy semantic exchange, and so on. Therefore, XOB enables high-quality ontology creation and reduces cost for ontology integration and system development.

The current Internet environment, it is accessible by a computer, but also transferred to the IoT(Internet of Things). These data become large. If the data are provided to the application without any adjustment, it is difficult to exert the original performance. In this paper, we propose a method for filtering the data using the MapReduce of big data processing techniques to refine the collected data. We want to address the heterogeneity of the data generated by the sensor by adding a knowledge identification step in MapReduce. We use XMDR for this purpose.

This study empirically analyzes game engine supplier's licensing strategy connected with supplier's technological regime and technological innovation. The results show that game engine supplier's technological regime is heterogeneously differentiated and it's user friendliness increases. "User Friendliness" of supplier's technological regime enables supplier's efficient technological transfer and increases supporting capability. Technological knowledge factors such as modularity of game engine structure, generic capability, codifiability of tacit game engine knowledge and degree of innovation turn incomplete technological market into efficient technological market by increasing supporting capability and by reducing transaction cost.

기업 네트워크에서 안전하고 효과적이며 안정된 망 운영관리 환경 제공은 당면한 중요과제이며 기업 경쟁력의 핵심인 정보기술을 통한 생산성과도 연계성을 갖고 있다. 이러한 필요에 맞추어 많은 네트워크 관리 시스템들이 개발되어 상용화 되었으나 이들 관리시스템들은 트래픽 모니터링에 의한 통계값 제공과 같은 단순 평면적인 관리 기능만을 제공할 뿐 네트워크의 특성과 환경에 따른 분석, 진단 기능은 제공하지 못하고 있다. 또한 현재의 네트워크 환경은 다양한 통신장비와 서비스들의 개발에 따른 망 구성 요소의 이질성과 복잡성이 증가하고 있으며 이는 전문적인 네트워크 운영관리와 분석기술을 요구하고 있다. 이는 관리자에게 네트워크가 점점 다양화, 복잡화 되는 환경에서 부담으로 작용할 뿐 아니라 결과를 도출하는데 많은 시간과 비용이 소요된다. 따라서 기존 네트워크 관리 시스템의 한계를 극복하고 네트워크 환경 변화를 수용, 관리자의 운영경험지식을 데이터베이스화하여 지능적인 네트워크의 분석과 진단이 가능한 시스템의 개발이 필요하다. 본 논문은 이러한 시스템 구축의 전제조건으로 네트워크 운영경험 데이터베이스를 구축하여 이를 통한 네트워크 환경 변화를 수용할 수 있는 임계값 최적화와 향후 한국전력 사내 데이터통신망의 지능화된 분석과 진단을 위해 활용하게 될 지식 발견 시스템을 설계 및 구현하였다.

For Knowledge Information Governance, integration search mechanism of Knowledge Information is required in various industries. But when Knowledge Information system constructs in each professional field, it developed and used its own metadata format. Accordingly, if distributed information system searches using metadata, heterogeneous problems are occurred among metadata. For integration search, it needs a consistency management of metadata. Therefore, this paper defines a standard metadata that represent standard metadata as surveying a used metadata in each field systems. Also, we propose a metadata registry integration framework for Knowledge Information Governance. It enables an integration search service without a metadata modification of existing system. Through the proposed framework, it can registries and manages efficiently the existing metadata. Also, it enables a semantically extended search using semantic relation between metadata.

The results of the study show that managers of Korean manufacturing firms pursue international business strategy(IBS) to achieve four different objectives: global integration, national responsiveness, market expansion, or development and exploitation of firm-specific knowledge. IBS is closely related to the international business environment of the firms. When managers think they can exploit economies of scale by integrating worldwide operations, they prefer the global standardization strategy. Managers of firms which implement the localization strategy actively recognize the importance of the strategy more than those of other firms. IBS helps to improve the overall international competitiveness of the firms. Especially. implementing global standardization and localization simultaneously seems to be useful to strengthen the competitiveness of the firms.

현재 온톨로지는 많은 분야에서 활발하게 연구되고 있다. 특히 시맨틱 웹에 대한 연구가 활발히 이루어 지면서 온톨로지의 활용 범위가 넓어졌다. 그 결과, 많은 온톨로지가 웹 상에 존재하게 되었으며, 이러한 이론적 배경으로 시맨틱 웹의 관점이 아닌, 온톨로지 연구의 측면에서 여러 가지 문제가 발생하게 되었다. 많은 문제들 중에서 동일한 도메인에 대한 온톨로지들 간의 이질성과 온톨로지의 일관성 문제 해결은 현재 가장 이슈가 되는 내용들이다. 이에 본 연구에서는 이러한 온톨로지 구축에서 발생하는 문제점들 중에서 기존의 지식 정보의 효율적인 재사용과 그에 기반한 온톨로지 구축 자동화의 가능성을 보인다. 또 이러한 기존 지식 체계에 기반함으로써 얻을수 있는 온톨로지에 대한 신뢰성의 문제 또한 해결하고 한다. 그리하여, 우리는 범용의 대형 온톨로지인 워드넷을 기반으로 한 자동 온톨로지 구축을 위한 방법론을 제안하고, 이를 적용한 온톨로지 자동 구축 시스템을 설계하고 구현하였다. 그리하여 사용자가 좀더 쉽게 온톨로지를 구축할 수 있기를 기대할 수 있다.

The development of digital technology has made consumers more knowledgeable about products than ever before. In this regard, experts have defined consumers in the digital age as knowledge seekers and pointed out that they are proficient in acquiring and sharing product knowledge prior to purchase. For service goods such as musicals, product prior knowledge executes strong effect due to such characteristics as intangibility, inseparabilit y,and heterogeneity. Prior studies in the field of performing arts, including musicals, have revealed that the prior knowledge of the audience has a positive effect on the satisfaction of the audience and WOM(word-of-mouth) intention. However, studies in the marketing field argue that consumers' high prior knowledge may have a negative impact on customer satisfaction and product evaluation depending on conditions, as they are more likely to compare, review, and expect products more closely. Therefore, in this study, we tried to identify under what conditions the musical prior knowledge enhances audience satisfaction and WOM intention. According to the results of previous studies, a mediating effect model was established in which the musical prior knowledge enhances the WOM intention through the mediation of the audience satisfaction. Then, Transportation was introduced as a mediation variable and it was verified whether the level changed the audience satisfaction and WOM intention. The reason for the introduction of the transportation construct reflects the results of previous research that the story is important component of musical. The results showed that the musical prior knowledge has a significant effect on WOM intention through the mediation of audience satisfaction. The moderating effect of transport was also significant on the relationship between musical prior knowledge and audience satisfaction. Lastly, through moderated-mediation analysis, it was confirmed that transportation moderates the mediating effect that prior knowledge affects on the WOM intention through audience satisfaction. Based on the results, we demonstrated that a musical story is fairly important to satisfy audiences with high prior knowledge. This study could contribute to the related filed in that it introduced the transportation construct for the first time, thereby broadening the understanding of the musical audiences in the era of smart consumers.
