  • This paper describes the background of the electrical safety emergency dispatch system and analyzes the operational status of the system. This system is to provide the enhanced electrical safety service to general-purpose electrical equipment users. Annual average of about 6 million cases have been implemented since 2005. In order to enhance electrical safety service and more effectively prevent electrical disasters in future, institutional expansion of the electrical safety emergency dispatch system with keeping budget is necessary. If periodic inspections with a remote monitoring system is applied, the effect of electrical safety will be improved.

  • To keep enterprise's competitiveness on condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously in not only production and maintenance but also related Industrial safety. As we analyze in the surveys for the maintenance management of domestic enterprises and the causes of industrial accident, there will be necessity of drawing up countermeasures for prevention of industrial accidents and for ensuring expertise maintenance technologies. Based on these analyses, this study studied the safety information system, maintenance management information system, and the machinery condition diagnosis technique by using of the knowledge-based system under the internet environment. This web based knowledge-based diagnosis system can easily provide not only the knowledge of expert about deterioration phenomenon of industrial robot, but also the knowledge of relating safety and facility on everywhere, everytime. Therefore, when we use this system, it is expected to improve the efficiency of business processes in the production and safety.

  • Computer system is widely used for controlling systems such as nuclear power plant, train speed control and air plane control. The failure of computerized controlling system can be arrived to catastrophic accident, so the safety ensuring of computerized controlling system is very important. This paper shows how to improve and ensure the safety of computerized systems. In this paper, we show how to identify, analyze hazards of the computerized system and to demonstrate risk of the system. Finally, we show how to adopt safety techniques for improving safety of the target system.

  • The aim of this study is that HPMA(Hazard Potentials in My Areas) System is to present for establishment of the voluntary safety management on industrial region. HPMA System Itself means that manager, supuryisor and worker on process-line find out the hazardous and/or unsafe potentials from their work places and make the plan of improvement by means of mutual communication with top manager and the department of safety staff, eventually put in the practice. In case that it takes the longer time to improve hazard potentials and is impossible improvement by existing technique, appropriate check-list will be used by the worker himself on the identified production line. Form this system, therefore, it makes them to get more and more sensitivity to the hazards. In this study, we present the voluntary safety management system which is controlable systematically and in the final analysis the direction of safety management by computerization of HPMA System which is activated in their work places.

  • Recently, elevator inspection and self-examination were strengthened through the revision of the Elevator Safety Management Act, but there have been no significant reduction in serious accidents and major failures. Therefore, the government intends to lay the foundation for reflecting the safety quality rating system, which adjusts the elevator inspection cycle, as a policy to induce safety management of preemptive and active management entities. This study systematically reviewed and classified the safety quality rating system for elevator inspection cycle adjustment in previous studies, collected expert opinions, and reconstructed the key items into realistic evaluation items, and evaluated and scored the relative importance of each factor through the AHP technique.

  • Despite the growing importance of safe railroad operation with the recent implementation of the Severe Accident Punishment Act, industrial accidents related to the shunting of railway vehicles persist. Therefore, the government and Korea Railroad Corporation are collaborating on an automated connection and disconnection system that enables remote control of shunting trains from a central control room, utilizing surveillance cameras. By eliminating the need for on-site workers during freight car operations at stations, it aims to reduce safety accidents inherent in manual receiving processes. A qualifying government-issued railway vehicle driver's license is necessary to handle this newly developed automatic connection and disconnection system. As a result, this study aims to establish an appropriate driver qualification system.

Food Hazard Awareness and Food Apprehension towards Food Safety Management System Evaluation: Focus on Moderating Effect of Food Safety Information Awareness (식품위해 인식과 식품불안감이 식품안전관리제도평가에 미치는 영향: 식품안전정보 인식의 조절효과를 중심으로)

  • Consumer anxiety about food safety is increasing, and the ability to make an accurate assessment is inadequate due to the lack of food safety information. This research focuses on relations among main variables, such as food hazard awareness, food apprehension, food safety information awareness, and food safety management system evaluation. In addition, to the moderating effects of food safety information awareness between food hazards awareness, food apprehension, and food safety management system evaluation. First, food hazards awareness and apprehension was slightly higher than the average level, also there was a significant difference in food hazard apprehension according to food hazard awareness. However, the level of food safety information was not high, meaning consumers were not as well informed as expected. We divided food safety management system evaluation into awareness and practice, subsequently, the results of both were at a low level. Food safety information awareness' moderating effect was also confirmed. Consumer organizations and the government need to provide specific and correct information to Korean consumers, that also implement a wide range of consumer education related policies.

  • In this paper, we conduct a study on the design that can secure the safety of the EPLA system by performing safety activities based on the ISO 26262 standard for vehicle functional safety. In the case of a company developing a detailed system, it is responsible for verification through hardware design and safety analysis in the overall flow of safety activities, and safety analysis according to the ASIL safety level must be properly performed. At this time, there are cases where the safety goal quantitative metric value suggested by the ISO 26262 standard cannot be satisfied only by the hardware design of the basic function, so it is necessary to design and install the safety mechanism. Based on ISO 26262 safety activities, it is possible to derive an effective design plan through hardware safety analysis.
