안전하고 정확한 항해를 위해 선박에서는 진북을 나타내는 자이로 콤파스와 자북을 가리키는 마그네틱 콤파스, 그 외에 GPS 등의 다양한 선박 전자장치들이 활용되고 있지만 이러한 장치들의 호환성 문제로 인해 전체 선박 시스템의 효율성 및 유지보수성이 크게 저하되고 있다. 본 논문에서는 이러한 호환성 문제를 해결하기 위해 선박 전자장치의 다양한 출력신호들을 동일한 하나의 표준 형식으로 변환해 주는 프로토콜 통합 시스템을 제안하였다. 시스템 설계 시 다수의 장치들로부터 입력되는 신호들을 동시에 처리하기 위하여 Multi-threading 기법을 적용하였으며, 실험을 통해 이를 통한 데이터 처리 성능 향상을 확인하였다.

RFID 기술은 기업으로 하여금 단품 수준에서의 의사 결정을 통한 정교한 재고 관리를 가능하게 한다. 최근 EPCglobal과 같은 RFID 정보 교환 표준이 보급됨에 따라 RFID 시스템은 RFID 하드웨어, 미들웨어, 정보 저장소로 구성된 정보 시스템으로 간주되고 있으며 이는 중요한 시스템 통합의 대상으로 부상하였다. 본 연구에서는 RFID 시스템과 기업정보시스템의 효과적인 연동을 위하여 연동 모델 선택 절차와 각 절차별 고려사항을 총 다섯 가지 단계로 구성한 RFID 시스템-기업정보시스템 연동 프레임워크를 제안하였다. 또한 국내 RFID 시스템과 기업정보시스템 연동 현황과 향후 적합한 연동 모델을 설문 조사를 통하여 제시하였다. 본 연구에서 제안한 연동 프레임워크와 설문 결과는 RFID 시스템을 처음 도입하는 기업이 RFID 시스템과 기업정보시스템을 효과적으로 통합할 수 있도록 기여할 것이다.

IoT 산업 발전으로 다양한 산업군에서 서로 다른 형태의 시계열 데이터를 생성하고 있으며 이를 다시 통합하여 재생산 및 활용하는 연구로 진화하고 있다. 더불어, 실제 산업에서 데이터 처리 속도 및 활용 시스템의 이슈 등으로 인해 시계열 데이터 활용 시 데이터의 크기를 압축하여 통합 활용하는 경향이 증가하고 있다. 그러나 시계열 데이터의 통합 가이드라인이 명확하지 않고 데이터 기술 시간 간격, 시간 구간 등 각각의 특성이 달라 일괄 통합하여 활용하기 어렵다. 본 논문에서는 통합 기준 설정 방법과 시계열 데이터의 통합시 발생하는 문제점을 기반으로 두 가지의 통합 방법을 제시하였다. 이를 기반으로 시계열 데이터의 특성을 고려한 이질적 시계열 데이터 통합 프레임워크를 구성하였으며 압축된 서로 다른 이질적 시계열 데이터의 통합과 다양한 기계 학습에 활용할 수 있음을 확인하였다.

System Integration is significant role in building, because it is that the more building system is integrated, the more they can save management costs and energy costs. Nowadays system protocols in building use BACnet, LonWorks, etc. to integrate effectively, but their interoperability is not perfect. Therefore, we propose system integration using Ethernet and TCP/IP for perfect harmony. When data network protocol, Ethernet and TCP/IP is used for control network, there are several problems. But there have been solved by many researches. therefore it is possible that building system integrate to use Ethernet and TCP/IP. Finally, we show that Ethernet and TCP/IP can be used for building automation system integration.

With the recent growth in cloud computing, big data processing and collaboration between businesses are emerging as new paradigms in the IT industry. In an environment where a large amount of data is generated in real time, such as SNS, big data processing techniques are useful in extracting the valid data. MapReduce is a good example of such a programming model used in big data extraction. With the growing collaboration between companies, problems of duplication and heterogeneity among data due to the integration of old and new information storage systems have arisen. These problems arise because of the differences in existing databases across the various companies. However, these problems can be negated by implementing the MapReduce technique. This paper proposes a collaboration system based on Database as a Service, or DBaaS, to solve problems in data integration for collaboration between companies. The proposed system can reduce the overhead in data integration, while being applied to structured and unstructured data.

Integration systems help users consume services more effectively. However, previous integration systems can only enable predefined service cooperation to satisfy users, which is difficult to achieve user-centric service composition in dynamic environments. Therefore, in this paper, a dynamic service integration system is proposed to automatically combine services based on usage history. With this system, services can be dynamically composed to meet users' needs and information can be flexibly transited among heterogeneous services.

Contrary to the traditional text-based information, 4S(GIS,GNSS,SIIS,ITS) information can contribute to the citizen's welfare in upcoming era. Recently, GSIS(Geo-Spatial Information System) has been applied and stressed out in various fields. As analyzed the data from GSIS arena, the position information of objects and targets is crucial and critical. Therefore, several methods of getting and knowing position are proposed and developed. From this perspective, Position collection and processing are the heart of 4S technology. We develop 4S-Van that enables real-time acquisition of position and attribute information and accurate image data in remote site. In this study, the configuration of 4S-Van equipped with GPS, INS, CCD and eye-safe laser scanner is shown and the merits of DGPS/INS integration approach for geo-referencing is briefly discussed. The algorithm of DGPS/INS integration fur determination of six parameters of motion is eccential in the 4S-Van to avoid or simplify the complicated computation such as photogrammetric triangulation. 4S-Van has the application of Laser-Mobile Mapping System for three-dimensional data acquisition that merges the texture information from CCD camera. The technique is also applied in the fields of virtual reality, car navigation, computer games, planning and management, city transportation, mobile communication, etc.

This paper introduces an integration of Product Data Management (PDM) and Software Configuration Management (SCM). PDM and SCM have supported development of mechanical products and software products respectively. The importance of software components in the current products increases rapidly since the software enables the products to satisfy various customer requirements efficiently. Therefore the current product development needs enhanced product data management that can control both the hardware and software data seamlessly. This paper proposes an extended product data model for integrating SCM into PDM. The extension enables PDM document management to support the version control for software development. It also enables engineers to control both the software and hardware parts as integrated data objects during product configuration and engineering change management. The proposed model is implemented by using a commercial Product Lifecycle Management (PLM) system and a development of a network based robot system is tested by the implemented product development environment.

Big data technology is being used in various fields followed by the development of information and communication technology. In the corporate and public sectors, diverse system platforms are built and operated due to the needs of users, but efficiency is low because they are built from an individual service perspective rather than an integrated service perspective. In this study, the relationship between presenting the characteristics of the type of shared information platform, the integration plan, and integration performance of the shared information system platform was analyzed. The results of the study will provide guidelines for the integration of shared information system platforms by the government and private companies in the future.

In recent years, two major streams in medical information systems are：1) system integration among OCS(Order Communication System), EMR(Electronic Medical Record), PACS(Picture Archiving and Communication System), and ERP(Enterprise Resource Planning) and 2) system integration through medical collaboration between East and West medical service providers. One of the characteristics which differentiate the Korean medical industry from the western medical industry is the East-West medical collaboration. In many respects there are many differences between East and West medical treatment. Although East and West medical treatment have developed from different medical philosophies and standards, we assume that the better medical care can be provided by integrating their medical procedures effectively. The two possible approaches to the integration of East and West medical information systems are suggested in this paper：One is loosely coupled model and the other is tightly coupled model. EMR improves the quality of medical record which reflects the quality of clinical practice. It provides more efficient and convenient way of input, retrieval, storage, communication and management of medical data. We abstracted the standard medical procedures from the two medical procedures performed in Daejeon Oriental Hospital and Hehwa Clinic at Daejeon University and also abstracted database schema by analyzing the characteristics of information needed in East-West medical collaboration. Our EMR is composed of two types of data：one is structured data and the other is unstructured data, which are formalized by SOAP(Subjective, Objective, Assessment, Plan) format. Currently the integrated system is implemented and operated successfully for six months.
