This study analyzed the effects influencing the elderly's knowledge on fire safety and practices of fire safety accident prevention after developing a Fire Safety Education Program for the elderly. The program was developed through verification using some experts and a pilot study after selecting the objective, goals, contents, and teaching & learning methods of the program based on the basic survey and literature review. The effects of the program were verified by conducting some non-equivalent control group pre- and post-tests after dividing the targets into the experimental group (the Fire Safety Education Program for the elderly was implemented) and control group (only printed hand-outs were given) among 48 elderly people no younger than 65 years of age. A paired t-test revealed some statistically significant differences between the scores of the pre- and post-tests of the experimental and control groups. ANCOVA found that the effects of the program were significantly higher than those of the printed hand-outs because the post-test scores of the experimental group were higher than those of the control group.

The government of South Korea has made great efforts in the area of railway safety management by means of a railway safety law and an integrated railway safety plan established in 2004 after the Daegu subway fire accident. However, after certain railway incidents, a reactive railway safety management system has been implemented that has led to fatal accidents caused by the collision, derailment, and fire every year. Hence, this study is intended to propose a framework that integrates data from distributed detection devices into a real-time railway safety monitoring and control system for proactive safety management. Furthermore, we will provide a future development direction for safety performance monitoring indicators to determine whether the railway safety monitoring and control system works effectively. The proposed framework is expected to be a cornerstone for the real-time railway safety monitoring and control system to be implemented in the future.

Polymers are widely applied to construction materials due to their lightweight and excellent mechanical properties. However, owing to the combustible properties, polymers are one of the biggest reason of spreading large fires in fire accidents that occur frequently in the construction industry. Therefore, as a solution to this problem, many research has been conducted to impart flame retardancy by incorporating flame retardants to polymer matrix. Among these flame retardants, organic phosphorus-containing flame retardants have been attracting much attention because they have excellent compatibility with polymer matrix and low toxicity compared with halogen or inorganic-containing flame retardants. Accordingly, this study aims to design and synthesize an alkoxyamine-based organic phosphorus flame retardant to improve flame retardancy of polylactide which is an eco-friendly polymer used for construction materials.

Korea has been preparing and operating crisis management standardized manuals so that over 30 disaster types that need to be managed at the national level can be selected and systematically managed. This study analyzed the crisis alert levels of two standard manuals related to the case with reference to the contents of the Framework Act on the Management of Disaster and Safety and National Crisis Management Basic Guidelines. According to the Act and Guidelines, crisis alerts are issued before a crisis or disaster, but the criteria of crisis alerts of the two manuals showed that the national crisis had already occurred and the disaster occurred due to a marine vessel accident at the serious level. In addition, the results of timing of issuance of crisis alert were reviewed. If the signs can be identified, a crisis alert may be issued prior to the occurrence of the incident, but a crisis alert cannot be issued when an incident occurs without a sign. In the case of an incident where there are no signs, but there is a possibility of spreading to a national level disaster, the disaster management supervision agency could issue a crisis alert.

98.8% of accidents occurring in domestic companies are concentrated in small-sized workplaces with fewer than 50 employees. Therefore, this study developed a disaster safety program that can be implemented by small and medium-sized enterprises by comparing and analyzing the safety management system actively used with the laws and regulations related to industrial safety and facilities. The disaster and safety program included the scope of application, organizational structure, risk assessment, emergency response system, education and training, safety equipment provision and program evaluation, and detailed preparation methods and procedures for each item. In addition, items to be aware of when operating a disaster safety program and operational strategies were presented. After that, it was proposed to introduce the research results into the Occupational Safety and Health Act.

As the proliferation of hydrogen electric vehicles accelerates, there is observed diversification in hydrogen refueling station models. This diversification raises safety concerns for different types of stations. This study conducted a quantitative risk assessment of a multi-vehicle hydrogen station, capable of simultaneously refueling cars, buses, and trucks. Utilizing Gexcon's Effects&Riskcurves Software, scenarios of fire and explosion due to hydrogen leaks were assessed. The study calculated the impact distances from radiative heat and explosion overpressure, and measured risks to nearby buildings and populations. The largest impact distance was from fires and explosions at dispensers and high-pressure storage units. High-pressure storage contributes most significantly to personal and societal risk. The study suggests that conservative safety distances and proper protective measures for these facilities can minimize human and material damage in the event of a hydrogen leak.

There has been the increasing concern with the safety of seven major urban infrastructure such as road, electricity, water supply, sewerage and so on due to urban expansion and new town development. However, high technology development for the common duct which can be an alternative for the safety issue has not been completed due to the law of the national security area. Existing management method of the common duct by people could not respond to the urgent accidents adequately and immediately since it is impossible for us to get access to that in case of fire or gas leak. This study suggests to the method of installing monitoring devices and processing CCTV images with a water supply in a TestLab(a variety of the USN(Ubiquitous Sensor Network) equipment was tested in the TestLab in KICT). The suggested management method of common duct facilities make it possible to do real-time monitoring and prompt access and response to an accident inside the common duct.

Recently, in the semiconductor process, large companies are seeking process changes from memory semiconductors to the foundry due to the increase in demand due to the 4th industry. industry is expanding. The characteristics of special gases and precursors, which are raw materials used to produce these semiconductor chips, are toxic, pyrophoric, inflammable, and corrosive. These semiconductor raw materials are operated in a closed system and do not leak to the outside during normal times, but when leaked, they spread to the inside of the gas box, and when proper ventilation is not provided inside the gas box, they spread to the outside, causing fires, explosions, or toxic substances. It can lead to major accidents such as leakage. Recently, there have been cases of accidents in which hazardous materials leaked from the closed system of the semi conductor process and spread to the inside and outside of the gas box. . In this study, we propose preventive measures based on the case of an accident in which raw material leaked from the VCR fitting, which is the connection part of the semiconductor raw material transfer pipe, and spread to the outside of the gas box.
