  • This research proposes an Integrated Product Information Model (IPIM) using STEP (Standard for the Exchange of product model data) for Computer Integrated Manufacturing (CIM) of Concurrent Engineering (CE). IPIM is based on Geometry and Topology (STEP Part 42), Form Feature (STEP Part 48), and Tolerance (STEP Part 48) for representing the integrated information of mechanical parts. For the IPIM, 1) new entities are developed for integration of existing entities, and 2) the existing entities are restructured and modified for a special application protocol. In CIM or CE, the advantages of using IPIM having integrated form of geometry, feature and tolerance are 1) integration of product design, process design and manufacturing sequentially or concurrently. 2) keep the product data consistency, modified by different domain, and 3) automatic data exchange between different application software and different hardware. The prototype system is composed of CAD, Data Probe, DBMS and SDAI (Standard Data Access Interface), and the generated STEP data is stored in a step file of DBMS for other applications.

  • In e-Marketplace, many companies are participating frequently either as supplier or as customer. Thus, electronic processing of transactions and flexible integration with participating companies' processes are required. These situation requires process integration using workflow and the exchange of transaction document using XML(eXtensible Markup Language). This paper presents methodologies to model business processes in e-Marketplace where many companies are participating and to exchange electronic messages using ebXML that have become a standard in electronic commerce. These methodologies can integrate and manage processes in electronic commerce environment, and can process ebXML standard documents efficiently, making electronic commerce more harmoniously in global market. The system constructed in this research supports business processes between companies by exchanging XML messages conforming Wf-XML and ebXML standards using SOAP protocol.

  • XML is suitable to integrate various forms of engineering design data since it possesses the characteristics of both documents and data. In this research a web-based design system has been developed, which integrates various gear design data in the form of XML. The system generates XML document containing gear design data and transforms gear design data in the relational database into XML document form automatically. The XML documents are transmitted to gear modeler agent through SOAP, and then the agent is automatically executed and generates CAD model files and VRML files. The designer can check the generated VRML model of gear immediately in the web service.

  • 인터넷에서 멀티미디어 서비스 및 고품질의 서비스를 제공하기 위한 다양한 모델들이 제시되고 있다. 기존의 통합화 서비스 (Intserv)나 차별화 서비스 (Diffserv)가 확장성과 종단간의 QoS 보장 측면에서 문제점을 보이면서 최근에는 이들을 통합하려는 시도가 나오고 있다. 그러나 각 모델의 기본 구조가 다르기 때문에 자연스럽게 연결되는 (Seamless) 통합 네트워크을 제시하는데 상당한 어려움이 있다. 본 논문에서는 인터넷에서 종단간의 QoS을 보장하기 위해 통합 모델의 형태를 보이고, 이를 구현하기 위한 프로토콜 변환기를 제안한다. 프로토콜 변환기는 리눅스 기반으로 구현되었다. 프로토콜 변환기를 포함하는 통합 모델에서 패킷 손실율, 데이터 전송율과 같은 네트워크 성능이 향상되었음을 실험을 통해서 보여진다.

  • In this paper, we implement a common module that can integrate multiple biometric information for integrated patient monitoring system. Conventional biomedical instruments have many devices attached to each patient, making it difficult to monitor abnormality signs of many patients in real time. In this paper, we propose a module for an integrated monitoring system that can perform centralized monitoring using a common module that integrates multiple measurement devices. A protocol for sending and receiving packets between the measuring device and the common module is designed, and the packets transmitted through the network are stored and managed through the integrated monitoring system and provide information to various users such as medical staff. The results of this study are expected to contribute to the management of patients and efficient medical services in hospitals.

  • In this paper, a development of agent-based IEDs(Intelligent electronic devices) for integration control of building microgrid in smart green building are proposed. To manage and control this complex energy system of smart green buildings, multi-agent system based networks is needed. Thus, several IEDs for utilizing multi-agent system are developed and modified for the their verification of performance as agent modules functions in the integrated experimental equipment. The good performance of these IED agents are verified from experimental results obtained from seamless bi-directional communication by SOAP/XML protocol between PC agent and IED agent.

  • Background: Purpose of this study is mat exercises and sling exercises that based on proceeding studies for exercising protocol for spinal stabilization. Methods: We analyze many other bibliographies and result of studies. Results: The vertebrae stabilization practices are formed on intra-abdominal pressure and converted into isolation of our body and limbs gradually through co-contraction training of transverse abdominis, pelvic floor muscle and diaphragm. Also, for prevention of low back pain and relapse, it is diverted to reflex muscle contraction training as well as functional integration. What is better, it should carry out with Activity of Daily Living. Conclusion: We should feel the necessity of it, more effective recognition training of local muscle for chronic low back pain patients. Besides, it is suggested that we should import measurable equipment and go hands with discipline.

  • DHCP(Dynamic Host Configuration Protocol) is a protocol which dynamically allocates an IP address and/or host configuration parameters to a host. The DHCP client's address can be changed dynamically any time. For the possible communication with other system, the DHCP client has to inform its address to the DNS system with dynamic update facility. But the DNS dynamic update has a problem related to the security. So we proposed the efficient mechanism for the secure integration of DHCP and DNS by using DNS security extensions. The system also uses the DNS server as the certificate repository for the storing & retrieval of each other's certificate.

  • There are many economic and operational reasons to integrate fire alarm signaling system with other building automation system. Integration of this requires communication standard and careful design practices. The important point for this is also the development of intelligent control modules for replacing the conventional zone adapter in fire system. Therefore, this paper proposes an new conceptual design of the distributed fire alarm signaling system and a new intelligent control modules with LonTalk protocol. Newly proposed additions to LonWorks network make it very well suited for integrating fire systems with other building automation systems. Additionally, it is very important that best design practices, test procedures and building codes need to be modernized to accommodate Integrated building systems.
