Purpose: This study aimed to understand the relationship between risk-sensitive factors and safety and unsafe behavior, and to clarify the relationship between risk-sensitive factors and demographic cha- racteristics through response matching analysis. To this end, a survey was conducted on 501 construc- tion site workers and data were analyzed using the SPSS program. Method: Six factors were derived through frequency analysis, cross-analysis, exploratory factor analysis, and reliability analysis for data purification. Multiple regression analysis and response analysis were conducted. Result: Risk-sensitive sensitivity and avoidance were found to have a significant effect on safety behavior and unsafe behavior, and the relationship was found according to age and occupation. Conclusion: Taken together, it shows that safety behavior is influenced by managing individual risk sensitivity and sensitivity, and properly managing avoidance. Accordingly, it suggests that intervention is necessary to manage risk sensitivity and sensitivity to promote safety behavior and maintain a sustainable safety culture, and to prevent excessive avoidance.

The purpose of this paper is to simulate public trust on nuclear regulation policy. The first of all, public trust variables and the model were developed and analysed by system dynamic method. The model are consisted of the operator safety culture level, regulatory competence levels, the public satisfaction and public trust level. The scenario is made up three type which base scenario, the system operator's safety culture level and accident event level. First. the simulation results of standard scenario shows that rapidly declining public satisfaction and trust level of the national safety after Japan's nuclear accident in November 2011. Second, operator safety culture level and simulated divided into three levels. The results showed that a greater impact on the public satisfaction if bad than good case. Finally, the size of the accident was simulated divided into three levels levels(no accident, medium, serious accidents). the results showed a weak effect against the regulatory capacity and safety performance levels but showed a significant impact on public satisfaction and confidence level.

This study analyzes the efficient floor layout plan of classrooms for securing evacuation stability in school in case of fire by using the Pathfinder simulation program. Efficient evacuation methods and safety were evaluated by analyzing REST (Required Safe Egress Time) according to the allocation of personnel by floor targeting a high school 5-story building equipped with a ramp and stairs. The current status of personnel assignments exceeded the Required Safe Egress Time(RSET), resulting in a problem with evacuation safety. When students were placed on the 3rd, 4th, and 5th floors, the result was that the time exceeded RSET the most. When students were placed on the 1st, 2nd, and 3rd floors, the result was that they completed evacuation in the shortest time, less than RSET. In the current state, when evacuation was guided by designating an evacuation exit depending on the location, the result of shortening RSET was obtained. As a result, it is effective to put the students on the lower floors when placing students in high-rise school buildings in terms of evacuation safety, and in the preliminary training, it is required to designate evacuation exits so that they can use the nearest exit for each location in case of a fire. As a future research project, additional research is needed on the RSET when a fire occurs in a specific location according to whether the automatic fire door at that location is opened or closed.

This study aims to analyze the key legal issues of the Serious Accidents Punishment Act (SAPA), which came into effect on 2022, in South Korea, and to propose practical occupational safety and health management strategies for business executives. The SAPA was introduced to prevent serious industrial accidents and protect workers' lives and safety. However, its effectiveness has been controversial due to the ambiguity of the law and uncertainty in its application. The study first provides an overview of the SAPA's main provisions and analyzes legal issues focusing on the punishment of business executives and the punitive damages system. Key issues identified include the ambiguity of "safety and health obligations," difficulties in proving causality, and unclear criteria for determining intent or gross negligence. Recent cases of serious accidents are examined to illustrate practical challenges in applying the law. Furthermore, the study compares the punitive damages system under the SAPA with that of the Product Liability Act and similar systems in the United States, United Kingdom, and Germany. This comparative analysis highlights the characteristics and problems of the Korean system, such as the unclear punitive nature, controversy over excessive compensation, and potential for abuse of litigation. Finally, the study proposes practical occupational safety and health management strategies for business executives to effectively respond to the SAPA and create safer workplaces. Key strategies include establishing a safety and health management system, conducting risk assessments, implementing safety education, managing subcontractor safety, and investing in safety and health.

Safety Management System is the aviation industry policy for while operating the aircraft, to ensure the safety crew, aircraft and passengers. For operating a safe aircraft, in order to establish the international technical standards, the International Civil Aviation Organization has established the Annex 19 of the Convention on International Civil Aviation. As a result, member country was supposed to be in accordance with the policy of the International Civil Aviation Organization, to accept the international standard of domestic air law. The South Korean government announced that it would promote active safety management strategy in primary aviation policy master plan of 2012. And, by integrating and state safety programmes(ssp) and safety management system(sms) for the safe management of Annex 19 is to enforce the policy on aviation safety standards. State safety programmes(ssp) is a system of activities for the aim of strengthening the safety and integrated management of the activities of government. State safety programmes(ssp) is important on the basis of the data of the risk information. Collecting aviation hazard information is necessary for efficient operation of the state safety programmes(ssp) Korean government must implement the strategy required to comply with aviation methods and standards of the International Civil Aviation Organization. Airlines, must strive to safety features for safety culture construction and improvement of safety management is realized. It is necessary to make regulations on the basis of the aviation practice, for aviation safety regulatory requirements, aviation safety should reflect the opinion of the aviation industry.

A survey of risk perception in Korea was conducted in 2001 with a special emphasis on industrial and technological risks. This article summarizes the characteristics of risk perception in consideration of socio-demographic background of respondents. The survey with sample size of 1,870 evaluates the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, and nuclear power generation. Risks are categorized by using factor analysis to clarify attitudinal or behavioral properties of risk perception. Research findings show that the level of perceived risk does not correspond to the statistical level. Socio-demographic variables are significant predictors in explaining risk perception, or the discrepancies between "subjective" and "objective" risks. Effective risk communication can reduce the perceptional discrepancies, improve the awareness of technological risks, and ultimately facilitate the process of making and implementing policies for risk management and safety regulation. This article tries to provides policy guidelines for "Who is the target for risk communication" and "Which risk has the policy priority for safety improvement." Married females at the age of 30s and 40s with lower education and lower income in small cities are more vulnerable to risk misperception than other groups. More information and knowledge regarding unfamiliar, intangible, new technological risks should be delivered to the vulnerable groups for reducing perceptional bias. Society-wide safety can be improved by integrating policy, human, and social factors as well as techno-engineering advances.

As ICT is becoming a major social infrastructure, the need to strengthen cyber capabilities are emerging. In the major advanced countries including the United States, has a continuing interest in strengthening cyber capabilities and has studied in enhancements of cyber capabilities. The cyber capability assessment is necessary in order to determine the current level of the country, establish policy directions and legislations. The selection of criteria has very important meaning to suggest future policy direction as well as an objective assessment of cybersecurity capabilities. But there are variable criteria for national cyber capabilities assessment such as strategy, legislation, technology, society and culture, and human resources. In this paper we perform the analysis of criteria for the other country's cybersecurity assessments including the U.S. and Europe. And we proposed the criteria for the national cybersecurity assessment reflecting the our country's characteristics.

This study examined correlations between U-Service for U-City and assessment indicators for urban competitiveness. The results of this study show that U-Service is used as a means of strengthening urban competitiveness in six types of cities, despite the differences in degree of contribution. The proper use of U-Service in Safety & Health City and Vitality (Economy) City has significantly contributed to strengthening the competitiveness of such cities. Of the assessment items for urban competitiveness, common items and Culture City type show that U-Service has not contributed much to strengthening urban competitiveness. The analysis shows that because common items are part of the assessment items for urban policies, these items are not suitable to the character of a U-City that implements U-Service through intelligent physical facilities. On the other hand, U-Service related to the Culture City type is relatively less developed. This study found out that U-Service could be used to reinforce urban competitiveness.

Fatigue lowers an individual's ability and makes it difficult to perform work. As fatigue accumulates, concentration decreases and thus the possibility of causing a safety accident increases. Awareness of fatigue is subjective, but it is necessary to quantitatively measure the level of fatigue in the actual field. In previous studies, it was proposed to measure the level of fatigue by expert judgment by adding objective indicators such as bio-signal analysis to subjective evaluations such as multidisciplinary fatigue scales. However this method is difficult to evaluate fatigue in real time in daily life. This paper is a study on the fatigue classification model that determines the fatigue level of workers in real time using speech data recorded in the field. Machine learning models such as logistic classification, support vector machine, and random forest are trained using speech data collected in the field. The performance evaluation showed good performance with accuracy of 0.677 to 0.758, of which logistic classification showed the best performance. From the experimental results, it can be seen that it is possible to classify the fatigue level using speech signals.
