Recently domestic companies have been needed to securing competitive techniques due to increasing orders of plant industries in the oversea construction market. Although domestic engineering companies have been assessed competitive in the field of detail design, their high value-added basic design have evaluated uncompetitive. To manage efficiently various contents which occurred in works of design steps, the management method must be built. In this study, we have found the contents which required to management through the definition of main works and analysis of characteristics in the step of basic design. Then, we have suggested to Contents Classification System which reflected of work flows and relations among stakeholders. Proposed Contents Classification System will help us when requiring the proper documents, drawings, sheets and other information.

Plant construction industry is a high value-adding industry because it is complex industry comprising engineering, procurements of equipments and construction. So, Revenue increase in overseas plant projects would boost up not only domestic construction industry but also growth of national economy. Recently, overseas plant-construction market is expanding dramatically. For instant, Middle-east countries are constantly increasing their orders for the construction of petro-chemical plants stimulated by sky-rocketing oil prices. The purpose of this research is to develop management techniques for plant projects such as work break-down structure, knowledge management system, logistics & procurement system, and risk assessment tools. We believe our research would contribute to the competion of Korean engineeing companies and contractors in overseas plant-construction market.

The standardized procurement of supervisory cost for the construction of domestic Information and Communication Technology(ICT) facilities, which is announced by the Korea Engineering and Construction Association in May 2009, has been applied in the public institutions and private industries. However, the previous standardized procurement is not widely applied in recent years because the ICT and social economic environment have been rapidly changed and the previous equations to calculate the supervisory cost is not simplified. As results, the needs for a new standardized procurement has been increased and the Ministry of Industry, Commerce and Energy has published a notice with new standard procurement. In this paper, we provide the explanation of the background and the derivation process of the notice based on authors' experiences of project participation. As research method, we compare the previous mad-day cost of ICT construction and that of another area including electric facility construction, and then we explain a new procurement equation based on WBS(Work Breakdown Structure).

A Wireless Sensor Network (WSN) is better than a conventional network for use in construction and Operations and Maintenance (O&M) because of its lower surveillance system cost. However, effective operation of a WSN is often difficult to obtain because the surveillance targets are usually fixed inside the building or underground. Therefore, this environmental constraint should be considered in the design of the WSN plant equipment surveillance system prior to installation. This study employs simulations of WSN-based fixed facility surveillance using the TinyOS TOSSIM simulator to investigate ideal types and setups of the WSN. Simulation target protocols included LEACH and flooding and gossiping protocols. The results show that the hierarchically-structured LEACH protocol demonstrated better load-balancing and efficiency than the flatly-structured flooding and gossiping protocol.

In the domestic aluminum industry, the extrusion process is a major process accounting for more than 40% of the total production. However, most domestic aluminum extrusion companies produce aluminum using old equipment that is more than 30 years old. Extrusion press is when the equipment is not replaced before the wear and breakage of major parts occur, reducing productivity and increasing the defect rate compared to new equipment. The old extrusion press often loses part drawings, so it is difficult to repair them properly on-site and to remanufacture them due to the lack of technical skills for maintenance. Therefore, a systematic remanufacturing plan must be designed from dismantling the equipment. In this study, remanufacturing FMEA was devised to remanufacture old extrusion press. The risk priority was analyzed by considering the degree of damage to the recycled parts, the cycle due to breakage/damage during the extrusion process, and the value of recycling resources due to remanufacturing. To standardize the remanufacturing process, remanufactured FMEA was performed through part analysis according to the structural analysis of the extrusion press. In addition, remanufacturing priorities were selected for each part, while remanufacturing itself was studied for efficiency of resource circulation and product quality stabilization.

국내외적으로 전력산업분야의 가장 큰 화두중 하나는 변전소 단위의 디지털화이며 특히 국외에서는 국제표준 변전자동화 시스템 연구와 제품개발 등에 인력을 집중 투자하고 있다. 국제적으로 지금까지 축적된 변전소 관련 제반 기술력 및 경험 둥을 바탕으로 전 세계적으로 단일화시키고 표준화된 변전소 자동화 규격인 IEC 61850 (Communication networks and systems in substations) 규격이 제정되었으며 따라서 향후 전력 관련 기업은 시스템 엔지니어링 기술, 전력기기 공급능력, 유지/보수/운영기술 등을 종합적으로 보유하고 자산 및 위험관리를 종합적으로 제공할 수 있어야만 세계시장에서 생존할 수 있다. 또한 전력기기를 수출하는 국내업체는 향후 IEC(International Electrotechnical Commission) 등 국제표준에 따른 전력설비를 개발하지 않으면 수출경쟁력을 잃게 될 것이다. 이러한 세계화 추세에 발맞추어 한국전력공사와 관련 업체들은 공동으로 2005년 10월부터 6년의 기간으로 "디지털 기술기반의 변전소 자동화 시스템 개발" 사업을 진행 중에 있으며 특히 한국전력공사는 변전자동화 시스템의 성능검증 및 실증시험 절차를 구축하기 위한 과제를 수행 중이다.

In the industrial internet of things (IIoT) industry, including smart factories, there are many cases where electronic devices are complexly combined and installed due to the recent development of intelligent information technology. Electromagnetic waves generated from such complex facilities affect other devices and services, which can lead to safety issues. The problem such as electromagnetic interference (EMI) and electromagnetic compatibility (EMC) generated when controlling complex facilities is an essential element that must be solved, and the engineering basis for EMI and EMC must be established to foster the industry of complex facilities. Therefore, in this study, EMC & EMI engineering demonstration cases for solar power fixed facilities using the national standard guideline have been analyzed. The results show that the electromagnetic risk indices in the solar power facilities have been degraded up to control level, and a national EMC engineering system has been proposed for complex facilities.

As Korea has been industrialized high recently, the constructional plant part which is the major driving force to Korean economic growth is being developed. In spite of the great importance, there are many ill-prepared parts in EPC project management procedure, and working in practice of EPC project management procedure manual is not systematic. That is why the governmental progressive policy on the relevant technology and the establishment of EPC project management procedure are needed. This study was aimed to derive reform measures by analyzing problems of EPC project management procedure manuals which are in use at 13 large-sized construction companies currently. The reform measures which are based on the theory of PMI(Project Management Institute)'s PMBOK(Porjcet Management Body Of Knowledge) are about deriving administration factors to control the project, and EPC project administration factors are derived from the definition of CMAA(Construction Mangement Association of America). The reformed electronic EPC project management procedure manual system is set up by standardizing derived administration factors.
