In recent years, electric shock accidents at industrial sites continue to occur, and various measures are being taken to reduce accidents. Among them, safety education is mentioned as a basic measure for the prevention of industrial accidents and the protection of workers. This study attempted to empirically analyze the effect of electrical safety education on safety consciousness and safety behavior and verify whether it is effective. To this end, a total of 343 people, including workplace managers and workers, were surveyed, and frequency analysis, factor analysis, reliability analysis, correlation analysis, and simple linear & hierarchical regression analysis were conducted using the SPSS 24.0 statistical program. As a result of the analysis, first, it was found that the higher the electrical safety education, the more positive (+) effect was on the safety consciousness. Second, it was found that the higher the electrical safety education, the more significant positive (+) effect was on safety behavior. Third, it was found that the higher the safety consciousness, the more positive (+) effect was on safety behavior. Finally, it was verified that safety consciousness plays a partial mediating role in the influence of electrical safety education on safety behavior.

This study systematically analyzed the causes of recurring electric shock accidents using accident analysis techniques and attempted to suggest implications for accident prevention. 124 electrocution death accidents that occurred from 2017 to 2022 were analyzed and classified into four factors(organizational influence, unsafe supervision, preconditions for unsafe acts, and unsafe acts) using the HFACS technique. As a result, First, in terms of organizational influence, many issues related to organizational processes were found, and the main causes were the lack of a safety management manual for electrical work, the lack of risk assessment, and the lack of safety procedures for electrical work. Second, in terms of unsafe supervision, the main causes were inappropriate operations such as not assigning a work supervisor during work or the lack of actual management and supervision. Third, in terms of preconditions for unsafe acts, the main causes were physical and technical problems such as not performing power outage work or not taking protective measures for live parts. Fourth, in terms of unsafe acts, the main causes were analyzed to be violations of safety procedures such as workers mistaking a power outage or not recognizing a current leakage condition, making a wrong judgment of the situation, and shortening the work time and working without safety measures for work convenience. Additionally, when examining whether the personal characteristics of those who died from electric shock had significant differences in unsafe behaviors, it was confirmed that there were significant differences in violations or decision-making errors depending on the industry and electrical-related major.

This study was conducted to verify the impact of hazardous risk factors in manufacturing workplaces on worker safety behaviors, focusing on the mediating effect of safety climate, and to establish safety management strategies in manufacturing workplaces and to suggest practical measures to improve worker safety. For this study, the results of the ‘10th Occupational Safety and Health Survey’ conducted by the Korea Occupational Safety and Health Agency’s Occupational Safety and Health Research Institute in 2021 were used as analysis data for 3,255 manufacturing workplaces with 20 or more regular workers. The data were analyzed using the SPSS 24.0 program for descriptive statistical analysis, validity and reliability verification, correlation and multiple regression analysis, and hierarchical regression analysis. As a result of the study, first, hazardous risk factors were confirmed to have a negative effect on workers' safety behaviors. Second, hazardous risk factors were confirmed to have a negative effect on safety climate. Third, safety climate was confirmed to have a positive effect on workers' safety behaviors. Fourth, it was verified that the safety climate had a partial mediating effect in the relationship between hazardous risk factors and workers’ safety behavior in the workplace. Through this study, it was found that hazardous risk factors had a negative effect on workers’ safety behavior. This emphasizes that efforts to systematically manage and minimize hazardous risk factors in the workplace are important in promoting workers’ safety behavior. In addition, it was confirmed that the safety climate had an important mediating effect in the relationship between hazardous risk factors and workers’ safety behavior. In other words, it can be seen that the safety climate can alleviate the negative effect of hazardous risk factors on workers’ safety behavior. These research results suggest that reducing hazardous risk factors in the workplace and improving the safety climate can have a positive effect on workers’ safety behavior practice, thereby preventing industrial accidents.

Executive safety leadership is essential to prevent accidents in the workplace. However, will safety be secured by emphasizing only executive safety leadership to workers? In this study, the impact of executive safety leadership on the workplace hazard level was analyzed by adding the supervisor's safety role as a mediating variable. This paper shows that executive safety leadership has no direct effect on workplace hazard levels. However, executive safety leadership was found to have a significant impact on the supervisor safety role, and the supervisor safety role was found to lower the hazard levels in the workplace. In summary, executive safety leadership was found to reduce the hazard levels in the workplace through the full mediating effect of the supervisor safety role. Based on these research results, this study seeks to present the following recommendations to the government and management: The government should ensure that a workplace safety and health system is established by strengthening the effects of other mediating factors, such as strengthening the role of supervisors who are actually responsible for workplace safety and health. Executives must grant supervisors actual authority and responsibility to properly perform their safety roles and establish personnel and performance evaluation systems.

In recent years, there has been a growing trend of occupational accidents involving foreign workers. As the number of foreign workers continues to increase, the risk of occupational accidents is also on the rise. Therefore, it is crucial to take proactive measures to prevent occupational accidents among foreign workers. To establish a common safety culture among foreign workers with varied backgrounds and educational experiences, and which is harmonized with Korean workplace. Safety communication, which includes culture respect and participation in the workplace, plays a significant role in shaping and developing the safety culture of foreign workers. Therefore, this study aims to assess the level of safety culture in workplace employing foreign workers by analyzing the reliability and validity of factors such as 'occupational accident awareness' and 'safety communication,' which constitute the safety culture at these workplace. Additionally, the mediating effect of 'work proficiency' on the relationship between 'safety communication' and the level of improvement in 'occupational accident awareness' using the validation method proposed by Baron & Kenny(1986). As a result of statistical analysis, The influence of‘safety communication’on‘occupational accident awareness’is β=0.339, and it has been found that this influence decreases to β=0.113 when‘work proficiency’is introduced, indicating partial mediation.

Today’s manufacturers must respond quickly to customer needs. In particular, make-to-order companies are constantly striving to satisfy customer demand for products in order to secure more favorable conditions in the future through bidding. In this bidding process, quotations play a very important role in providing favorable conditions. And the most important content that companies strive to satisfy their customers is the product's performance. Therefore, a company can attract customers and secure economic profits through good quotations, but it can be said that the first priority is to match the performance of the products requested by the customers. That is, when a company creates a quotation, it is important to structure the quotation according to the performance of the product. Thus, this paper intends to present a quotation management framework and a quotation BOM information model for constructing quotations efficiently in make-to-order manufacturing. And, in order to prove the usefulness of the proposed quotation management framework, we presents an case of the construction of an quotation management system based on the JAVA platform. As a result, the integrated quotation management system based on the proposed quotation management framework and quotation BOM has been successfully operated in a make-to-order company that manufactures marine engines.
