The Chemical Control Act of 2015 was enhanced to ensure the safe management of hazardous chemicals. In particular, there have been substantial changes in the standards for the installation and management of handling facilities for manufacturing and storing hazardous chemicals. However, some standards for handling facilities are difficult to implement due to a lack of physical space or because of safety accidents during facility improvements. Therefore, the Safety assessment system (SAS) has been operating for such facilities since 2018. This study developed a leakage trajectory evaluation module that can easily evaluate the outside of a dike for safety evaluation. We analyzed two case studies on a dike for hydrochloric acid and sulfuric acid storage tanks with this module and suggest a reasonable plan for the facility. We believe that it will be possible to more easily submit SAS reports at chemical plants by using this evaluation module. This study is expected to contribute to the improvement of the safety design of hazardous chemical handling facilities.

As buildings become higher and larger, the possibility of accident also increases, and recurrent accidents and serious accidents are also increasing. However, it is not possible to control all the hazardous activities in construction site. Therefore, hazardous activities with higher possibility should be identified and prioritized in advance so engineers and managers can control the activities in safe manner. For this purpose, this research adopts FMEA technique, which has been widely utilized in manufacturing industry. In order to apply FMEA technique in construction safety management, the process of construction work is divided into sub-processes or activities. Then FMEA technique is applied to quantitatively analyze the importance of each activity from the safety perspective.

There is insufficient effective management systems to achieve project goalsin disaster and safety R&D. Therefore, to develop an R&D performance management system, this paper develops a R&D performance management matrix based on PMBOK to systematize a process and to enhance efficiency of performance management. Also, this paper identified vulnerable procedures in disaster management by analyzing related laws, work process and performance. Analysis results found that the performance management matrix in disaster management R&D consists of 5 process groups, 7 knowledge areas and 47 processes. Also, the performance of the diffusion knowledge process was evaluated as weak in the present management system. This study defined ITO and developed a data flow diagram for applicationto related work. The suggestions of this study include the related work to enhance R&D performance, contribute to improving diffusion of R&D performance, and enhance the utilization of developed technologies.

SITES(Site Information and Total Environmental Data Management System) has been developed for the purpose of systematically managing site characteristics and environmental data produced during the pre-operational, operational, and post-closure phases of a radioactive waste disposal facility. SITES is an integration system, which consists of 4 modules, to be available for maintenance of site characteristics data, for safety assessment, and for site/environment monitoring; site environmental data management module(SECURE), integrated safety assessment module(SAINT), site/environment monitoring module(SUDAL) and geological information module for geological data management(SITES-GIS). Each module has its database with the functions of browsing, storing, and reporting data and information. Data from SECURE and SUDAL are interconnected to be utilized as inputs to SAINT. SAINT has the functions that multi-user can access simultaneously via client-server system, and the safety assessment results can be managed with its embedded Quality Assurance feature. Comparison between assessment results and environmental monitoring data can be made and visualized in SUDAL and SITES-GIS. Also, SUDAL is designed that the periodic monitoring data and information could be opened to the public via internet homepage. SITES has applied to the Wolsong low- and intermediate-level radioactive waste disposal center in Korea, and is expected to enhance the function of site/environment monitoring in other nuclear-related facilities and also in industrial facilities handling hazardous materials.

This study was conducted to review the adequacy and applicability of the safety certification system for educational facilities which was implemented in 2021 and to derive possible improvements to the existing certification system. This study analyzed the existing certification system, examined similar systems from abroad, conducted interviews with certification experts, and presented the proposed improved system to experts for review and advice. The proposed model replaced the current certification process with three stages of follow-up management. This allows for problems that may occur in the evaluation process and the composition of evaluators to be prevented by applying a feedback system. In the review stage of the newly proposed certification system, certification experts recommended specifying the detailed standards of certification performance such as criteria for selecting examiners and arbitrators. They concluded that there were no fatal flaws in the overall structure of the evaluation system. According to the results of this review, the proposed evaluation system was proven to be an effective improvement to the existing system.

정부와 시설물유지관리 기관에서는 공공시설의 안전성 확보와 유지관리 업무의 생산성 향상을 위해 다양한 시설물유지관리시스템을 구축하여 운영중에 있으나 대응적 유지보수 체계의 한계로 인하여 합리적인 예산수립을 위한 최적의 의사결정을 하기가 어려운 실정이다. 이러한 이유로 유지관리의 효율성 증대 및 예산 절약을 위해 공공시설에 예방적 개념의 자산관리체계를 도입해야 한다는 요구가 증대되고 있다. 자산관리는 시설물의 최적화된 관리를 위한 경영전략으로 시설물 상태에 대한 공학적, 해석적 분석을 넘어 대상물을 자산으로 인식·평가하고 가치유지 및 향상을 목표로 하며 동시에 사용자의 최대만족을 얻기 위한 전략이다. 국내에서는 이러한 시대적인 요구에 따라 자산관리에 대한 연구가 진행 중이며 본 논문에서는 자산관리정보시스템을 개발하기 위한 해외 사례조사를 통해 시스템 핵심 기능을 도출하고 이를 통해 데이터 항목 분류방안을 제시하였다.

In this paper, through the study and consideration of the recently prominent monitoring of cable stayed-bridge, practical but reasonable suggested for the evaluation of the probabilistic safety of the bridges using probable measured data from monitoring measurement system. It is shown in the paper that the live load effects can be evaluated using measured data of cable-stayed bridge and this the realistic probabilistic safety of the cable-stayed bridge could be assessed in term of element reliability and system reliability. As a practical method for the evalution of the system reliability of system cable-stayed bridges partial ETA method is uesd, which can find the critical failure path including combined failure modes of cable, deck and pylon. Compared with the conventional safety analysis method, the propsed approach may be considered as the practical method that shows the considerably actual and reasonable results the system redundancy of the structure.

As the incidence and mortality of serious disasters in the construction industry are the highest, various efforts are being made in Korea to reduce them. Among them, risk assessment is used as data for disaster reduction measures and evaluation of risk factors at the construction stage. However, the existing risk assessment involves the subjectivity of the performer and is vulnerable to the domestic construction site. This study established a DB classification system for risk assessment with the aim of early identification and pre-removal of risks by quantitatively deriving risk factors using BIM in the risk assessment field and presents a methodology for risk assessment using BIM. Through this, prior removal of risks increases the safety of construction workers and reduces additional costs in the field of safety management. In addition, since it can be applied to new construction methods, it improves the understanding of project participants and becomes a tool for communication. This study proposes a framework for deriving quantitative risks based on BIM, and will be used as a base technology in the field of risk assessment using BIM in the future.
