Recently, the maintenance concept of infrastructure has been changed from the stability management of the structure determined by the safety inspection of the existing facilities to the asset management related to evaluating and managing the performance of the facilities. For management of the property of the facilities, it is necessary to efficiently classify their information for the maintenance and service level of the facilities and to manage them. In the case of power plant facility, especially, it is a complex structure, which is constructed in a various component and detail. In this study, therefore, the components of power plant facility were classified into facilities, spaces, parts, and elements considering the type of integrated construction classification system in Korea. To reflect the deterioration rate of the facility in accordance with environmental conditions such as airborne salt and humidity etc., it was classified by adding direction, interior, and exterior condition of each component not to be considered in the existing classification system for its effective and systematic maintenance, since it is generally located in the coastal area due to the operation of the power generation structure. The classification system developed in this study can be used as fundamental data for development of the computer system for asset management of power plant facility.

Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.

지하매설물이란 땅속에 묻혀있는 상수, 하수, 전기, 통신, 전력 등 도시기반시설을 의미하며, 지상시설물에 비해 관리가 어렵고 예기치 않은 사고로 인해 많은 재산상, 인명상 피해를 입힐 가능성을 안고 있다. 우리는 서울 아현동과 대구에서의 대형 가스폭발사고, 도로굴착공사가 끝난지 얼마 안되는 지점에 또다른 매설물의 매설 또는 유지보수를 위해 중복공사가 일어나 교통에 혼잡을 유발하게 되는 경우를 빈번하게 경험하면서 도시의 동맥역할을 하는 이러한 지하매설물에 대한 체계적 관리가 시급함을 실감하게 된다. 특히 선진외국에서 GIS를 도입하여 지하매설물을 데이타베이스화하고 지하매설물 관리체계를 개발하여 지하매설물을 체계적으로 계획하고 관리하며, 대형사고를 사전에 예방하고, 사고가 일어난 경우에는 GIS를 활용하여 보다 신속하게 대처함으로서 피해를 최소화하는 실정을 감안할 때 GIS도입이 이러한 매설물에 대한 체계적 관리를 가능하게 하는 방안으로서 적극적으로 검토되어야 함을 느낀다. 본 글에서는 첫째, 이러한 지하매설물의 관리실태와 문제점을 분석하고 둘째, 현재 국가 및 서울시에서 추진 또는 계획 중인 지하매설물 관리체계 구축사업내용과 셋째, 지하매설물 데이터베이스가 어떻게 구축되고 유지.관리되어야 할 지에 대하여 간략히 살펴보고자 한다.

In the case of river facilities, the management of this information differs depending on national and regional rivers, therefore, there is no integrated management in place. There is concern about the loss of facility information owing to the insufficient accumulation of information during their design and construction stages. Additionally, as a result, the utilization level of facility information during the maintenance and operation stages is insufficient. To ensure effective maintenance and operation of river facilities, it is necessary to secure data consistency and increase efficiency by organizing facility information according to a standardized classification system. This study proposes a strategy for implementing the BIM standard classification system in the river sector, considering facility characteristics. The goal is to introduce a BIM information model for 3D-based river facilities, and enable efficient maintenance and operation conversion.

국가적으로 전체 터널의 수는 대폭 증가하는 추세이며, 시공 및 유지관리 단계에서 체계적이고 장기적인 계측을 통한 관리가 필수적이다. 그러나 제한적인 계측만을 수행하고 있으며, 계측된 데이터가 체계적으로 관리되지 않아 유지관리 등 시공 이후의 단계에서 기초 정보로 활용하지 못하고 있는 실정이다. 이러한 상태의 주요한 원인 중 한 가지는 기존의 유선 계측기가 터널현장의 복잡하고, 다양한 장비들이 운용되는 상황에서 설치 및 유지관리에 어려움이 있기 때문이다. 또한 고가의 로거의 필요성은 경제성 면에서도 장애가 된다. 따라서 터널의 효율적인 계측 및 관리를 위해서는 경제성이 확보된 무선의 효율적인 계측기의 개발이 선결되어야 하며, 본 연구에서는 지그비(Zigbee) 기술을 활용하여 기존 터널 계측기의 70% 이상을 차지하는 진동현 계측기를 무선화 할 수 있는 모듈의 프로토타입을 개발하였다. 본 고에서는 이와 관련된 다음의 내용을 기술하고자 한다. - 지그비 기술을 활용한 진동현 계측기 무선화 모듈 프로토타입 개발 내용 - 현장 실험 방법 및 결과

Currently, Hydrogen compressor is maintained and managed according to the safety management regulations of the operator. But it is not based on technical standards, so it is necessary to establish based on reliability. In this paper, hydrogen compressor taxonomy by ISO 14224 standard reviewed for hydrogen compressor operated by KOGAS-Tech hydrogen vehicle refueling station to establish 9-stage taxonomy, and FMEA was conducted to establish RCM strategy specified in SAE JA1011, and 1012. It is expected that results of taxonomy and RCM strategy will be used as basic data for development of standards for verifying the performance of compressors.

As bridges have been longer and bigger recently, lots of bridge management systems (BMS) have been developed for each bridge. However, the differences among the data models developed by different system developers give a serious problem in integrated information management for national security. The aim of this study is to develop a common data model which can be referred in development of the BMS. The existing BMS and work process by laws are carefully analyzed. Based on the analysis results, the bridge management and maintenance process is categorized into the four basic activity types. In addition, common data models for each the unit activity type are defined.
