The control network has been operated in a closed. But it changes to open to external for business convenience and cooperation with several organizations. As the way of connecting with user extends, the risk of control network gets high. Thus, in this paper, proposed the technique of an anomalous event detection using white-list for control network security and minimizing the cyber threats. The proposed method can be collected and cataloged of only normal data from traffic of internal network, control network and field devices. Through way to check the this situation, we can separate normal and abnormal behavior.

As global partnership is recently getting important in order to establish supply chain network in global managing environment, companies tend to improve quality and warranty in SCM(Supply Chain Management) by certifying ISO(International Organization for Standardization). This research investigated structural relationship how strategic and operational ISO application level and trust, immersion, collaborative factors in partnership process affect to companies business performance. This research was surveyed with 147 manufacturing companies in South Korea and conducted empirical analysis using Structural equation model. The research hypothesis and model was derived from the basis of existing theory and empirical research, and obtained the following results. Firstly, the strategic ISO level showed positive(+) effect on trust and immersion factor. Second, the operational ISO level showed positive(+) effect on trust and collaborative factor. Third, trust factor in the partnership process showed positive(+) effect on immersion factor. Lastly, collaborative factor in partnership process showed positive(+) effect on companies business performance. Implication for this research is that companies must consider ISO application in establishing partnership and companies require prolonged effort using trust, immersing, collaborative factors into partnership process to improve business performance.

최근의 기업의 업무관련 네트워크가 인터넷의 발달, 글로벌(Global)경영, 전자상거래의 발달 등으로 인하여 전용선을 구축하여 인트라넷(Intranet) 환경에서 처리하던 업무들을 엑스트라넷(Extranet) 환경으로 확장하게 되었다. 엑스트라넷은 해당 기업의 여러 지사뿐만 아니라, 제조업체, 공급업체, 협력업체, 고객, 다른 비즈니스업체들과 안전한 공유를 위해서는 꼭 필요하다. 그러나, 이러한 엑스트라넷 구성은 비용적인 측면과 보안적인 측면 모두 고려해야된다. 현재의 추세는 기존의 공중망을 이용하여 사설망처럼 사용하는 VPN(Virtual Private Network)를 구성하고 있다. 본 논문에서는 리눅스기반하에 IPsec 프로토콜을 사용하여 VPN을 구성할 수 있는 freeS/WAN과 방화벽기능을 하는 패킷 필터링(Packet Filtering) 프로그램인 iptables를 이용하여 비용적 부담이 적고 안전한 엑스트라넷을 구성하고자 한다.

Currently, the necessity of inter-system integration and sharing system increases to additionally construct and efficiently utilize the geographical information data in accordance with the increase in demand for geographical information. The provision of the data within the domestic sharing system is led by the tasks within national geographical information distribution network or intra-local governmental combined system. However, any voluntary geographical information sharing cooperation body is increasingly required with the increase in necessity of administrative cooperation among neighboring metropolitan areas, including space planning and development. Accordingly, this study is aimed at looking into the constitutions and roles of cooperation bodies within metropolitan areas by the composition, distribution, update and management of data with special regard to overseas advanced cases whose sharing systems and their effects are highly evaluated, and at presenting any model of the domestic future voluntary sharing cooperation organization within metropolitan area.

현재 전 세계 각국은 지식 경쟁력 확보에 혈안이 되어 있으며, 우리나라는 풍부한 인터넷 인프라를 구비하여 지식 강국으로 발돋움하기 위한 충분한 토대를 마련하고 있다. 특히, 인력은 인터넷 시대의 핵심적 지식 자원으로서, 전문가 두뇌 연계 망(네트워크)의 구축과 운영을 통해 해당 분야 전문가간 협력 및 교류가 진행되면, 지식 정보의 동시 생성, 공유, 활용 체제의 확립이 가능하다 전문가 커뮤니티의 구성원은 정보의 공유와 확산에 자발적으로 기여하는 지식의 선 순환 구조를 이루게 될 것이다. 본 논문에서는 국내외 과학기술 전문가로 구성된 한민족과학기술자 네트워크(KOSEN, www.kosen21.org)를 사례로 전문가 네트워크의 역할과 특징을 살펴보고, 지식 기반 사회에서 전문가 네트워크의 발전 방향을 제안하고자 한다. KOSEN은 지식의 생성, 공유, 활용 등의 지식관리 프로세스를 지원하는 과학기술 전문가 커뮤니티이다. 향후 인적 자원 및 정보 자원의 적절한 연계를 통해 지식의 활용 측면을 더욱 확대하여 본격적인 지식 정보 활용의 장으로 거듭나야 한다. 컨텐트 가치증대를 통한 전문가 참여 확대, 전문가들간 상호 연계의 확대를 통한 소 공동체 형성, 전문가들간 상호 학습, 정보 거래 메커니즘 구축 등의 다양한 방안을 통해 보완될 것으로 기대한다.

인간과 사물, 서비스 세 가지 분산된 환경 요소에 대해 인간의 명시적 개입 없이 상호 협력적으로 센싱, 네트워킹, 정보 처리 등 지능적 관계를 형성하는 사물 공간 연결망인 IoT(Internet of Things)에서 센싱된 정보를 처리하고 서비스하기 위한 환경을 적시적소에 배치(Depolyment) 하기 위하여 클라우드 서비스와의 연동방법에 대해 본 논문에서 연구하였다. Public Cloud환경에서 Hadoop Cluster를 구성하여 IoT 서비스에 적용할 수 있는 통합 환경을 구축하면 폭발적으로 증가하는 IoT 데이터를 저장하고 빠른 시간안에 이를 효과적으로 처리 및 분석하기 위한 시스템 구축이 가능하며 분산 저장소에 저장된 데이터를 분석하고 의미있는 지식을 발견하여 새로운 비즈니스 모델 창출에 기여할 수 있다. 본 논문에서 Public Cloud 환경에서 Hadoop Clouster를 구성하여 IoT에서 생성되는 데이터를 효과적으로 처리하고 분석할 수 있는 방법을 제안한다.

Following the technology developments of traffic network and communication for the wide area, the importance of the cooperation system to vitalize the wide area economy is increasing. Therefore, in this study, DongNam Kwon industry information system is established for the industrial information sharing based on GIS in the DongNam Kwon wide area economy. The DongNam Kwon is an industrial integration area centered with the manufacturing so that the operation of effective industrial cluster and cooperation systems are required across the administrational boundaries. To establish the database of the information, the information system was established utilizing already established industrial databases in Busan, Ulsan and Gyeongnam. But, various issues caused by the discordances among the data of each local government and the insufficiency of GIS based location information have been found. According to the analysis, the standardization considering the courses of collection, distributions and utilization are required immediately to solve the issues. This study establishes an 2-way industrial information system enabling the information creation and the phased approach between the administrator and the user in the bi-directions on the web by utilizing cadastral and numerical maps. The result of this study would have a meaning in providing a fundamental frame for cooperative responses and cooperation system for DongNam Kwon's industrial promotion using industrial information sharing.

In order to construct an efficient monitoring system for major port cities in Korea, the first step to build and manage related laws and institutional infrastructure with strengthen the cooperation of the relevant agencies, regional port authorities, and port corporations. Second, for the management of air pollutants emitted by ports, a management system should be established through systematic inventory source inventory and real-time monitoring system. Third, active countermeasures should be established to reduce the emission of air pollutants by sources such as ships, harbor equipment, and trucks. This will improve the air quality of major port cities and move them to clean port cities.
