The facility diagnosis technique of past subjective judged the technical expert and interpreted stably mainly. The facility the periodical civil official becomes indispensability consequently with the law and the system and objectivity inspection which relates with a this and development of diagnosis technique were necessary. Currently the evaluation elements which relate with an inspection and diagnosis technique depended to the subjectivity of each facility quality, data statistics, diagnosis know-how, various circumstance and the technical expert and the evaluation item came to decide. But the evaluation score distribution of marks of each item depended plentifully in data analysis result and experience. The past method is weak in logically because the objection theoretical background and basis are insufficiency. Consequently in order to apply a data analysis result and an experience logically, it used AHP(Analytic Hierarchy Process) method from this research. It is visible with the fact that the application result reconfirmation and complement process will be necessary the technique which is suitable in the multi facility management. Also it is expected with the fact that the application characteristic from the next relation technique will be excellent.

우리나라는 1994년에 발생한 성수대교 붕괴사고를 계기로 ｢시설물의 안전 및 유지관리에 관한 특별법｣이 제정되면서 시설물의 안전점검 및 유지관리 분야에 많은 노력을 기울이고 있다. 이러한 시설물 중 건축물 다음으로 가장 많은 비중을 차지하는 교량은 현재 총33,165개소가 공용 중이며, 2, 3종 교량의 경우 28,150개소로 전체 비중의 약 85%를 차지하고 있다. 하지만 교량의 대부분을 차지하고 있는 2, 3종 교량은 상대적으로 중요도가 높은 1종 교량에 비해 점검진단 등에 관한 유지관리 현황이 미흡한 실정이다. 이러한 이유는 교량의 점검진단 수행 시 점검진단 수행자의 주관적인 판단 및 기록, 체계적으로 수립되지 못한 점검진단 보고서 양식 등에서 나타난다. 따라서 본 연구에서는 기존 점검진단 보고서의 문제점을 수정 및 보완하여 체계적이고 지속적으로 활용 가능한 점검진단 보고서의 개선(안)을 도출하고자 한다.

The purpose of this paper is to understand the key factors for efficient maintenance of rapidly aging facilities. Therefore, the safety inspection/diagnosis reports accumulated in the unstructured data were collected and preprocessed. Then, the analysis was performed using a text mining analysis method. The derived vulnerabilities of tunnel facilities can be used as elements of inspections that take into account the characteristics of individual facilities during regular inspections and daily inspections in the short term. In addition, if detailed specification information and other inspection results(safety, durability, and ease of use) are used for analysis, it provides a stepping stone for supporting preemptive maintenance decision-making in the long term.

본 연구에서는 교량, 터널, 댐, 상수도 등 사회기반 시설물의 안전점검 및 정밀안전진단결과를 DB화하고 업무프로세스를 자동화하기 위해 각 시설물별로 점검진단에 필요한 항목을 표준화해서 분류체계를 마련하였고 사전조사에서부터 현장조사, 시설물평가, 보고서작성에 이르는 전 과정에서 걸쳐 데이터베이스 기반의 자료구조를 정의하고 파일럿시스템을 구현하였다. 또한 점검진단결과 DB가 효과적으로 활용될 수 있도록 개선방안을 제시하고, 시설물정보관리종합시스템 운영규정, 점검진단 세부지침 등 관련 규정/지침에 대한 개선방안을 제시하였다.

Even though continuous management and supervision of reinforcement of policies to safeguard accidents at workplace and work sites were implemented. Accident prevention activities such as inspection and diagnosis are urgently required to induce a preliminary investigation to identify the risk factors for each type of work, before the work task to eliminate risks at the worksites. Since safety inspections at work sites were generally conducted through visual inspections, the results of safety inspections may vary depending on the findings and proficiency of the safety officers. The results of those inspections may have loopholes to prevent potential accidents at work. Therefore, the purpose of this study was to develop a risk identification checklist that can effectively perform safety inspections to prevent accidents at work sites. This study initially analyzed the previously developed accident checklist to identify current complications and issues in safety checklists. Based on the findings of major industrial accidents over the past three years, the relationship between accident, workplace, and work type were analyzed refereeing the safety inspection standards. A risk recognition-checklist was developed to provide basic data on identifying risk factors, and inspection guidance at work sites. To prepare for potential accidents by identifying and taking countermeasures to mitigate the high risk and serious accidents at sites by the guidelines of the checklist. The developed inspection checklist has been practically used by experts at work sites to perform safety inspections, and it has been verified its suitability, and feasibility, to prevent or mitigate workplace accidents, including securing the safety and health of field workers. The role of the developed safety checklist has been considered effective at worksites.

As one of promising solutions to overcome high oil price and energy crisis, the construction market of high value-added LNG plants is spotlighted world widely. The purpose of this study is to introduce LNG-RBI system to develop risk assessment technology with RAM(Reliability, Availability, Maintainability) modules against overseas monopolization. After analyzing relevant specific features and their technical levels, risk assessment program, non-destructive reliability evaluation strategy and safety criteria unification class are derived as core technologies. These IT-based convergence technologies can be used for enhancement of LNG plant efficiency, in which the modular parts are related to a system with artificial optimized algorithms as well as diverse databases of facility inspection and diagnosis fields.

This paper is to enable electrical safety manager to have more objective evaluation on the safety by indicating quantitative values such as life-time and status quotient of daily visual inspection on private electrical equipments. Self-diagnosis table is recommended to apply such a evaluation efficiently according to the characteristics of each electrical equipments, and the managers's determination of the precise inspection, replacement etc. will be also possible through the standard selected by various domestic and foreign data with expert's advise for numerical evaluation. This circumstance will be able to establish the foundation to secure the soundness of electrical equipments.
