A system to efficiently utilize construction information has been in demand as a result of the changing society where information and knowledge leads to added value. Consequently, the government established a comprehensive information network system for construction industries to manage and utilize construction information which is the currently in use. However, this system is oriented toward management and business performance estimation for engineering and does not integrate a management system for design, construction technology, and construction engineering services. Therefore, this study proposes to develop object technology and management system of construction services and its evaluation to provide such information in real time.

In this paper, the method to apply the RFID technology to schools will be presented in order to effectively integrate and manage various assets in school. The proposed system may be seemed to be very useful of individual school to grasp the status of their assets and also the central government to control and manage the assets scattered far and wide around the country. We also propose the OSN/PMS server based on EPC global standard could be appropriate especially in schools. In addition the proposed system can acquire simultaneously the information from several RFID readers at real time so that it is possible and easy to track the position, the path of moving and the status of assets in the school. To show the usefulness of the proposed system, the prototype of the system has been implemented and conducted. The proposed system seems to be applicable to various fields such as factories, farms, or homes as well as school.

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.

This parer proposes application of quality costing system in quality improvement area. Cost of quality in quality improvement area provides a valuable of both providing the need for improvement and giving a starting point for project. WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. Web-based quality cost management system to measure the performance of quality improvement activities in the business firms. This paper proposes standard model for quality cost process in quality improvement area.

Recently, government office buildings have become important in reducing maintenance costs. However, the loss of information raised a problem for maintenance work that could not meet the needs of users. Therefore, this study proposed a BIM-based integrated maintenance system for public offices in Jeju to efficiently maintenance work. The system can be integrated with IoT sensors, big data and artificial intelligence technologies to integrate information that occurs throughout the building's entire life cycle to exchange information. This system is also scalable to buildings, plants, region and urban infrastructure facilities as well as single buildings. It is expected that the system will provide reliable, high-quality, real-time information for efficient maintenance work, thereby supporting decision making and appropriate budget planning.

This paper describes implemation of 'General-purpose ETRI MAP interface module' (GEM) for Mini-MAP network. GEM operates as a Mini-MAP node in our FA system. To communicate between GEM and programmable devices(PD) such as PLC and CNC, serial communication is used. Application programs of a MiNi-MAP host system control and monitor programmable devices via GEM. GEM is implemented and tested on the basis of the MAP 3.0. TBC in the Nini-MAP board performs the function of the MAC sublayer. The LLC sublayer is implemented according to the specification of Class 3 that includes Type 1 and 3. And the MMS services are designed within the scope of implementation class MAP3. All the softwares are implemented under the real-time multitask OS for real-time application of the Mini-MAP and they are loaded into PROMs at the network board of GEM. We tested the LLC functions to make use of a protocol analyzer for the token-passing protocol. Also the MMS conformance test was carried out by exchanging primitives between GEM and a MMS product that had already passed the conformance test. Therefore GEM is proposed as a network tool of Computer Integrated Manufacturing (CIM) to integrate PDs which don't support MAP functions.

본 논문은 스마트 공자의 모니터링을 위한 제조설비 시각화 시스템을 소개한다. 최근 기술 발달의 가속화와 제 4 차 산업혁명, Industry 4.0등과 같은 용어가 등장함에 따라 기존 제조공장의 스마트화를 위한 기술들이 조명되고 있다. 제조공장을 실시간으로 모니터링 함으로써 생산성 향상 및 의사결정의 도움을 줄 수 있는 생산관리 시스템은 스마트 팩토리를 위한 중용한 기술 중 하나가 되며, 더 정확한 모니터링 및 응용 기술을 위한 디지털 트윈 기술의 적용 또한 중요한 이슈가 되고 있다. 그러나 디지털 트윈 구현을 위해서는 여러 제조사의 설비 데이터를 통합할 수 있는 통합 인프라가 필요하다. 따라서 본 논문은 이기종의 설비 데이터 수집 및 모니터링을 위한 국제 표준 프로토콜 기반의 데이터 수집 시스템을 활용해 설비의 실시간 정보를 확인할 수 있는 시각화 프로그램을 설계하고 개발한다. 이를 통해 하나의 공장에서 여러 제조사의 설비 데이터들을 통합하고 실시간으로 확인 할 수 있도록 한다.
