The Measurement of risk parameter in city-gas equipments have been measured and confirmed by human, and evolved into remote monitoring system using wireless communication. Furthermore, domestic and international industry increase the efficiency of management, which can develop remote monitoring and control system using wireless communication. However, Those wireless system might be decrease the efficiency and ease because of connecting PDA and lap-top using wire-cable when data have checked immediately from outside. This paper is able to improve efficiency of safety management on city-gas equipments by developing mobile city-gas safety management system on AR.

The information technology paradigm has been shift to smart service environment, as ubiquitous technology is used in the latest industry trend. The convergency between industry facilities and ubiquitous technologies accelerate related studies and technologies because of increasing accident prevention and decreasing cost. However, ubiquitous technologies are not used to life environment and industry facilities, because those technologies did not consider industry domain characteristics by means of developing IT technology for common environment until now. This paper aims to develop wireless city gas safety management system, which provide efficient service, and establish the field oriented wireless data transmission infrastructure in order to use ubiquitous technology to city gas facilities.

Consequence model has been suggested to evaluate consequence of city gas accident considering actual situation. Through event tree analysis(ETA), probable accidents were summarized and listed. Then release rate was calculated both sonic and subsonic conditions. Among city gas accidents, fire damage is the dominant one and mainly discussed; fatality, burning injury, and damage to building were estimated using the consequence model suggested. With an appropriate conditions, calculating total cost by accident was suggested.

The objectives of the present study were to assess the oxidative stability of South Korean n-3 (omega-3 fatty acid) supplements carried out from 2018 to 2019 and evaluate the influence of product characteristics on oxidative safety. A total of 76 n-3 supplements were analysed for oxidation safety by four markers, including acid value (AV), primary oxidation (peroxide value, PV), secondary oxidation (p-anisidine value, pAV) and total oxidation value (TOTOX). Among the supplements tested, 5.3 %, 55.3 %, 28.9 % and 46.1 % exceeded the international voluntary recommended levels for AV, PV, pAV and TOTOX, respectively. Purity (%) of products, remainder of expiration date (suggested shelf life), package in press through package (PTP) and products with additives had statistically significant differences oxidation assessment levels (p < 0.05). In addition, n-3 group found in Algae oil had significantly lower AV levels than the group that did not, and product with Alaska pollack oil, had significantly higher pAV levels than without group (p < 0.05). The high oxidation status of South Korean n-3 products in the present study could not be considered a public health problem right now. However, the levels of oxidation may affect a lot the efficacy and safety of using n-3 supplements. Thus, current oxidation safety limits should be reestablished by regulatory bodies to ensure the safety and efficacy of n-3 supplements, so that the standards could be applied to the products available to consumers.

This Study is U-City based facilities analysis procedures and techniques of the effective management. We analyze the existing procedure of the management of urban based facilities. And U-City based facilities of management procedures were presented. U-City based facilities were classified regular inspection, safety inspection, emergency inspection, accurate safety diagnosis, routine work and emergency work. We analyze the skills required in the management of these facilities. The procedures for the management of U-City based facilities will improve efficiency of urban management and safety of citizen. As a result, the management of U-City based facilities will lead to improving the quality of services for citizens and competitiveness of the city. Furthermore, this will be the foundation of the environment that people can enjoy safe and convenient life.

In this work, a novel approach was introduced to assess cost of loss resulting from risk as well as to help deciding inspection period through quantifying risk. In order to quantifying risk of city gas pipeline, frequency and consequence analysis were required. The main causes of city gas accident were analyzed to be digging, external corrosion, ground movement, and equipment failure. Tools to evaluate frequency of each cause was also suggested. Among city gas accidents, fire damage is the dominant one and mainly discussed; fatality, burning injury, and damage to building were estimated using the consequence model suggested. By combining frequency and consequence analysis, evaluating cost of risk management together with calculating example. This work could be applicable for city gas companies to plan how to manage risk most effectively.

K-city is an experimental area for developing self-driving cars. V2X communications such as WAVE, C-V2X and 5G are an essential technology for autonomous driving above level 4. In this paper, the research on the V2V communication environment was carried out through BSM receiving level analysis on the driving route in K-city. A stationary vehicle communicated with a test vehicle moving along urban area and suburban road in two different scenarios. The communication range and receiving levels obtained from this study will be used to develop and verify various safety scenarios using V2V communication within K-city in the future.

Background & objectives: Understanding the awareness of policy targets and implementers about safety in the local community is the crucial to establish a systematic community safety policy. The purpose of this study was to identify the perception of local citizens and civil servants regarding community safety and its related factors. Methods: For achieving this research goal, this study conducted survey targeting 538 citizens and 404 civil servants in S-si, Kyunggi-do. Self-administred and web-based survey were used to collect data from April 1^st to 16^th 2021. Results: Civil servants scored higher in community safety perception than citizens, and S city's safety interest, information, and participation scores were also higher than those of citizens. Based on the results of multiple regression, thought about in interest of safety in S-si, providing and sharing about safety information to citizens, and participation of community safety policy were significantly associated with perception of community safety. Conclusions: Setting safety as the top priority in S city policy and paying attention to safety by the mayor, public officials, and city council members is an important way to raise citizens' awareness of local safety. Also, efforts at the city level are needed to foster safety knowledge through systematic education on safety.
