Effective leadership in safety performance, such as safety leadership, has received attention as a factor that greatly affects safety performance in various high-risk industrial environments. Based on prior research, this study aims to analyze the impact relationship between safety leadership, safety observance, safety education, and safety culture to reveal the effectiveness of safety leadership. In addition, this study will examine the effects of safety leadership on safety observance and safety education to identify the effects of safety understanding. For this purpose, a survey was conducted with employees of an aviation manufacturing company in Gyeongnam. For verification, a positive factor analysis, correlation analysis, and structural equation analysis were conducted using the AMOS 21.0 program. This study's findings show that, first, safety leadership has a positive and significant impact on safety observance and safety education. Second, safety leadership was found to have a direct impact on organizations' safety culture. Third, although safety observance has significant positive effects on safety culture, safety education has often been rejected. Finally, after verifying the control effect of safety understanding, this study uncovered the presence of an adjustment effect in the effect of safety leadership on safety observance. Therefore, based on the results of this study, theoretical and practical implications suggest that through the exercise of safety leadership, managers can improve their organizations' safety culture by increasing organizations' compliance with safety observance and/or acceptance of safety education.

The current test methods are insufficient to evaluate and ensure the safety and reliability of vehicle system for all possible dynamic situation including the worst case such as rollover, spin-out and so on. Although the known NHTSA Sine with dwell steering maneuvers are applied for the vehicle performance assessment, they aren't enough to estimate other possible worst case scenarios. Therefore, it is crucial for us to verify the various worst cases including the existing severe steering maneuvers. This paper includes useful worst case based upon the existing worst case scenarios mentioned above and worst case evaluation for vehicle dynamic controller in simulation basis and UCC HILS. The only human steering angle is selected as a design parameter here and optimized to maximize the index function to be expressed in terms of both yaw rate and side slip angle. The obtained scenarios were enough to generate the worst case to meet NHTSA worst case definition. It has been concluded that the new procedure in this paper is adequate to create other feasible worst case scenarios for a vehicle dynamic control system.

In laboratories, researchers frequently work using new methods with new tools and materials. So the workers in laboratories are exposed to risk from dangerous articles all the time. In the case of university laboratories, testing is done by the individual at night. Because of that, the risks in university laboratories are higher than in other places. In addition, students and managers in universities generally have little concern for laboratory safety. So students are sometimes injured or killed in laboratory accidents. In this study, 1,000 university students answered questions about university laboratory safety. Their answers have been analyzed to determine the state of actual conditions and to formulate countermeasures. The results indicate that we need to change the safety awareness of the universities and the students. Adequate safety training and safe practice must be implemented by each university to decrease accidents. Development of systematic safety training program suited to the specific conditions of the individual laboratory and formulation of specific counter plans should accidents occur are required.

Background: The surface mining industry has one of the highest fatality rates among private industries in the United States. Despite recent decreases in the fatality rates of comparable industries, the fatality rate in the surface mining industry has increased. Meanwhile, a lack of safety research in surface mining has hindered efforts to improve safety strategies in the surface mining workplace. Method: This study examined quarry workers' hazard identification skills by conducting a case study of a surface mining facility in the Mid-Atlantic region of the United States. Semistructured interviews were conducted with eight quarry workers who were employed at the mine facility. In addition to the interviews, data were collected through field notes, notes from an expert meeting with safety managers, and site photographs to explore quarry workers' safety behaviors in the workplace. Results: The results showed that quarry workers identified hazards and improved their safety performance by translating safety knowledge learned from training into practice, acquiring hands-on work experience, learning from coworkers, and sharing responsibilities among team members. Conclusion: This study contributes to understanding quarry workers' safe performance beyond what they have learned in safety training to include their interaction with other workers and hand-on experience in the workplace. This study informs practitioners in the surface mining industry to build a safe work environment as they design effective safety programs for employees.
