본 연구는 W3C를 중심으로 시맨틱 웹을 위한 표준 온톨로지 언어로 제안된 OWL(Web Ontology Language)을 바탕으로 패싯형 시소러스인 AAT(Art and Architecture Thesaurus)의 개념 체계를 이용한 온톨로지 스키마를 구현하여 시맨틱 웹 환경의 온톨로지 기반 시스템을 구축하였다. 특히, 개념의 범위를 AAT의 Furniture 패싯 이하의 용어에 한정하였고 이 중 개념관계가 다양하고 많은 어휘를 가진 하위 패싯인 Chair 개념을 중심으로 시스템 구현 및 테스트를 하였다. 이 시스템은 올톨로지로 정의된 개념을 검색하며, 동의어에 대해 항상 우선어(Preferred term)를 제시하여 어휘를 제어한다. 또한 질의어를 중심으로 한 용어간의 관계를 이용자에게 제시하고 관련어 및 개념의 분류기준 속성을 제시한다. 그 밖에 개념에 인스턴스 값을 입력하고 이를 RDF 문서로 재생산하는 시스템을 구축하여 온톨로지 시스템 응용의 일례를 제시하였다. 이 과정에서 여러 온톨로지를 도입하였고, 인스턴스 값을 담기위한 컨테이너 기반으로 메타데이터 요소를 사용하였다.

Customer centered supply chain Management is becoming a very important issue for manufacturing and distribution company. Increasingly, leading companies improve their competitiveness by shorting the time to delivery from warehousing to delivering, increasing the level of customer service. They also do their best to collaborate with suppliers and customers based on the information sharing. This case introduces a integrated approach to develop a logistics automation and information system for the spare parts distribution center of L electronics. We pursue to optimize the supply chain by implementing intelligent logistics system which has the capabilities of responding to the changes in market demands. This would provide many implications to the clients in solving logistics problems and secure superior competitiveness.

The Ministry of National Defense announced 'Defense Reform 2.0' that aims to strengthen the country's security for decrease of regional uncertainties, growing requirements for advanced technologies, and a need for more efficiency in the Republic of Korea(RoK) Armed Forces this year. It said RoK Armed Forces have to change efficiently in preparation for rapid decline in military service resources as demographic cliff turning into reality, and the rapid evolution of the "battlefield environment" caused by developments in military science and technologies. RoK Navy combat Management System(CMS) made by domestic proprietary technology since 2000s and development centered on Agency for Defense Development require design changes for added requirements. So in this paper, I propose method of design a low cost and high efficiency navy CMS architecture based on high performance server and virtualization technology. And I create a test environment for analysis performance and compare the performance of proposed navy CMS and existing navy CMS.

The Korean construction market and housing policy have been increasingly focusing on supplier. As opposed to houses in private areas, Apartment House using the common infrastructure such as elevators, electrical facilities, heating system and hot water supply system need joint management. Their management usually depends on the resident cooperation or outsourcing. On this study, I investigated the level of satisfaction of Apartment House residents and its managing personnel, the conditions of its management, and analysed the important factors which influence the degree of residence satisfaction with respect to its maintenance and management.

The waterworks company is in charge of managing water facilities buried underground, and the management has been centered on manholes. However, since there is no standard management manual, it has been impossible to introduce and operate a systemized managing tool by water service providers and managers, and manhole management has been carried out by individual data recording personnel for each water service provider. When the management is carried out individually, the data to be shared by other waterworks managers tend to be privatized, and consequently, it may become a big obstacle to proceed with many civil works such as emergency leak repair, road excavation, replacement of old buildings. This report introduces RFID (Radio Frequency Identification) system which is based on the magnetic field capable of IOT. It also describes the necessity of leveraging the system for smart managing of pipe management record that has been done by hand writing. The RFID system includes RFID marker, data reader, portable computer operating program, and data base server operating program. In this system, the data is managed with a single communication device, and it would be possible to share the information on the underground facilities and water treatment facilities. This RFID technology is expected to provide water service providers with opportunities to develop more scientific and modernized underground facilities information systems.

Purpose: This study discusses efficient operation plans in terms of public rental housing maintenance in terms of LH, a major supplier. Research design, data, and methodology: After reviewing problems related to the maintenance and management of public rental housing discussed in several previous studies, problems in technology setting for repair maintenance costs for public rental housing, lack of public assistance for maintenance and management of public rental housing, management of housing funds, and lack of role of local governments in the supply and repair of public rental housing were derived. Based on this, the researcher conducted using literature research methods to present relevant improvement measures based on reasonable arguments. Results: this study presented four operational plans related to (1) realization of repair costs for public rental housing, (2) a public subsidy system for covering the maintenance costs for public rental housing, (3) efficient operation of the Housing City Fund, and (4) establishment of the public rental housing. This study aims to provide a foundation for the qualitative growth of the domestic public rental housing system. Conclusions: With this study, it is expected that social interest in maintenance of public rental housing centered on LH will be amplified to improve the quality of maintenance problems of public rental housing.

In recent, the rolling stocks are gradually complicated in respect with design and production to improve the safety and reliability. Also, the reliability centered maintenance corresponding with system specification or technical requirements is needed to meet the higher quality in railway service. In present, each railway authorities are collecting the failure's data using information system, applying those for maintenance works. However, this system has not established with systematic and scientific approach. This paper represents the existing activities and plans for RCM management system for AREX's EMU.

In medium and small firm, the management system which is simple and where there is a practicality is required Ill)re than the management system which is complicated and minute of the centered around large company so that the introduction of the standard costs can be activated and it can be usefully used as a tool of management decisions. A difference between the standard costs introduction plan proposed in this paper and the preexistance study literature are as follows. In this paper, by breaking from the whole cost accounting aiming at all item, that is the traditional introduction method, and presenting the product cost accounting method by group the standards setting object was minimized and simplified. In this way, if the standards setting object is simplified, it is quick at the perimeter environment change as the little man power and flexibly it corresponds to and the cost information calculation which is exact with the setting up and maintenance of the efficient cost standard becomes available. As a result of applying for real through S corp., the usability of the method that the standard costs introduction method proposed in this paper produced the standard costs relatively short within period, it manages was verified. And the standard costs introduction method proposed in this paper went by the various cost information for each products, the management class did the management will decision which was objective and reasonable in the putting first.

최근 노량진 수몰사고, 방화대교 붕괴사고 등의 대규모 건설재해가 끊이지 않고 발생하고 있다. 이에 건설공사 현장에서 재해 저감을 위한 다양한 공사참여자의 역할 및 책임이 중요한 요소로 인식되고 있는 실정이다. 건설 산업은 계획, 설계, 시공, 유지관리 단계를 거치면서 발주자를 비롯한 설계자, 시공자 등 다수의 행위주체들이 참여하여 공사목적물을 만들어 가는 일련의 과정이다. 그러나 현행 안전관리의 주체는 근로자를 직접 고용하는 원도급자인 시공사에게만 책임이 집중되고 최상위에서 의사결정 권한을 행사하는 발주자의 안전활동 참여는 배제되고 있다. 이에 본 연구는 각 공사참여자를 대상으로 안전활동에 대한 인식수준 및 실태에 대하여 파악하고, 이를 통해 발주자 중심의 안전관리체계에 대한 개선방안을 제시하였다.
