The Railroad Safety Act was implemented in 2005 due to the increased concerns regarding railroad safety since the Daegu subway fire in 2003. In line with this, the Act became a standard to build the total railroad safety systems which has been overlooked compared to the quantitative growth of the railroad business. The minister of the ministry of Land, Transportation and Maritime Affairs lays down the Act for railroad Companies to conduct emergency programs in response to the emergency occurring on the railroad such as fire, explosion, derailment, etc. By enacting the Safety Act, the nation's construction of the contingency management system for railroad emergency increased", and it made the railroad company prepare the Emergency SOP by establishing 'The guideline on the Establishment of the railroad Emergency Plan' in order to support the efficiency of the Act. In line with this, I would like to analyze a matter of system development and the main function of the "railroad Emergency Training Program" for activation improvement of standardized operation procedure developed through the 'Total capitalize Safety Technology development'.

Consumers are quite worried about food safety because food is one of the most important necessities in everyday life. Many studies have been conducted regarding the food safety issues, however, most researches have focused only on a limited range of risk factors and used only quantitative survey methods. The purpose of this study was to investigate consumers' perceptions of the risky components of food safety and how the perceptions have been formed. For this study in-depth interviews were conducted. For the interviewees, nine housewives, who are in their 30s to 50s, were selected taking into consideration their age, education level, number of children, and employment status. Results showed that the risk factors many consumers worried about were agricultural pesticides, MSG, food additives, GMO, Mad Cow Disease, preservatives, and growth hormones, etc. Consumers were worried about the risk of the retail process the most because they thought it was not informed and controlled well. Consumers tend to worry much more when the risks are involuntary, uncontrollable, unreliable, and have a gradual negative effect. Some of the food safety-oriented behaviors of consumers were also investigated.

It is very hard to analyze the train derailment safety quantitatively at the curved section because of the diversified affect parameters including the complex interaction between wheel and rail, the train conditions such as the shape of wheel, suspension system, the track conditions such as the radius of curve, cant, transition curve, and the operation conditions, etc. Two major factors related to the running safety of railway vehicle are classified as the railway vehicle and the track condition. In this study, when the railway vehicle passing through curves of actual track condition of subway line NO.3 in seoul ($Yeonsinnae{\leftrightarrow}Gupabal$), the effect that has influence on running safety depending on rail inclination. The analysis result of 1/40 rail inclination condition is more favorable on running safety than other rail inclination conditions because derailment coefficient and wheel unloading ratio are the lowest.

Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region and is within the frequency range of 0.1-10 THz. The ability of THz waves to pass through a wide variety of packaging materials, combined with their ability to characterize the molecular structure of many substances makes it an attractive tool for the application of food quality and safety management. This review provides current information on application of THz spectroscopy/imaging technology for food quality and safety management. The THz spectroscopy/imaging technology has been shown to be useful for detecting foreign bodies, vitamin/moisture, pesticides, antibiotics, melamine etc. However, major barriers to the adoption of THz spectroscopy/imaging for food quality and safety management include THz signal loss in heterogeneous food matrices, high costs of sources and detectors, and absence of a library for the wide group of food compounds. Further research is needed to overcome these barriers.

Purpose - This study aims to examine the relationships between the acceptance of the 4th industrial revolution logistics technology, logistics safety behavior, and logistics safety performance, as well as the moderated mediating effects of logistics safety behavior through safety culture in Korea. Design/methodology - Research models and hypotheses were established based on prior research related to the 4th industrial revolution logistics technology, logistics safety, and logistics performance. The survey was conducted on the employees of logistics companies, and reliability analysis, confirmatory factor analysis, discriminant validity analysis, structural equation model analysis, and mediating effect analysis were performed. In addition, the moderated mediating effect analysis applying SPSS Process Model No. 7 was conducted. Findings - Usefulness and sociality of the acceptance of the 4th industrial revolution logistics technology had a significant effect on logistics safety behavior. Ease of use, sociality, and efficiency had meaningful effect on logistics safety performance. And in the relationships between the acceptance of logistics technology and logistics safety performance, logistics safety behavior had a significant mediating effect. But the moderated mediating effect of safety behavior through safety culture was not significant. Logistics companies can improve logistics safety performance through the utilization of new logistics technologies such as intelligent logistics robots, autonomous driving technology, and artificial intelligence, etc. Originality/value - This is the first study to analyze the relationships between the acceptance of logistics technology in the 4th industrial revolution and logistics safety. In addition, previous studies analyzed mediating effects or moderating effects, but this is the first study to identify the moderated mediating effects of safety behavior through safety culture. In other words, it has originality in terms of research methodology.

To manage State Safety Program (SSP) in a more integrative and proactive manner, an aviation safety authority of the state shall detect and assess the risk of emerging or hidden safety hazards before they provoke accidents or incidents(ICAO, 2018). In case of South Korea, safety risk assessment is conducted by calculating the likelihood and severity of the hazard following ICAO's safety management manual. It is reasonable to extract the safety risk likelihood by calculating the number of occurrence caused by the hazard. However, it is ambiguous to assess the safety risk severity defined as the extent of harm that might be expected to occur as a consequence of the identified hazard. In this paper, a safety risk assessment method which quantitatively calculates the risk of hazard using aviation safety data(i.e. aviation safety mandatory report, etc.) is proposed. By utilizing the proposed method, the existing process that safety risk is being subjectively assessed by safety inspectors can be supplemented. So that essential aviation safety policy decision making can be accomplished by the accurate result of safety risk assessment.

The unsignalized intersections in a community road in the city of Seoul have 3,753 traffic accidents(9%) of total 41,702 cases in 2008, not high in the occurrence rate of traffic accidents, but seem to have a quite high potential of accidents due to the unreasonable and insufficient operation of systems and facilities in the part of traffic foundations. In particular, the un-signalized intersections in a community road have an insufficient measure for safety as compared to the crossroads with signals, and there are few analysis of traffic accidents and domestic researches on the model of affecting factors. Our country also has no concept of passing priority in operating a crossroad without signals, differently from foreign countries, so the researches and safety measures for improving the safety of a crossroad without signals in a community road are urgent. Therefore, this research has developed a safety model for a crossroad without signals in a community road based on the safety image data collected through individual interviews and questionnaires for the users of unsignalized intersections in a community road, and confirmed that legal systems, road facilities, personal factors, etc. have the biggest effect on the safety of drivers. It was confirmed that the clarity of passing methods, establishment of legal systems, etc. have the biggest effect on safety in order to raise the safety of unsignalized intersections in a community road, which drivers desire.
