The Risk assessment regulation(RAR) is one of the essential articles of the Occupational safety and health law for the construction industry along with safety and health management expense and safety organization regulation. However, arguments regarding the working time of the safety assessment documents, the person in charge of documentation, weakness in legislative enforcement etc. are ongoing. Thus this study aims to analyze the effectiveness of RAR for the guidance of enhancing the effectiveness of RAR. The findings are; 1) the effectiveness of RAR is recognized, however the indirect effectiveness ie, enforcement of safety activities, previewing of drawings etc. are bigger than the direct effectiveness of accident prevention, 2) to enhance the effectiveness of RAR site inspection procedure has to be utilized, 3) further research for identifying and getting rid of negative factors in RAR is recommended.

This paper has studied the effect of airline staff's perception on both aviation safety and aviation security to their organizational effectiveness. Airline staff's perception on aviation safety is different from that on aviation security due to organizational difference in an airline. Through an empirical analysis, it was analyzed the effect of such perceptional difference on airline's organizational effectiveness. According to the analysis, it was found the perception of aviation safety has a significant positive effect on organizational effectiveness. Airline staff believed the safety is a core value of an airline and emphasizing the safety never impeded the airline's operation including service quality. Secondly, it was proven the perception on abiding by aviation security rules had a significant negative effect on organizational effectiveness. However, emphasizing aviation security had a very significant positive contribution on airline's philosophy of aviation safety. Following the research results, it was suggested an airline look for improving the process and regulations to deal with aviation security in the organization.

This study first addresses the ineffectiveness of indirect regulation on industrial machines. Analysis of causes of industrial accidents associated with industrial machines further reveals the fact that technical causes need to be resolved at the manufacturing stage to reduce the frequency and strength of industrial accidents. Balanced safety certification on manufacturers and safety inspection on users of industrial machines are then suggested to effectively resolve such technical causes. The effectiveness of such safety certification and safety inspection can be justified by cost-benefit analysis. Particularly, balance in expected benefits of safety certification and safety inspection is a key issue for validity of such analysis. The accumulated benefit-costs for press brake and portable sawing machine confirm the effectiveness of such safety system.

The recent increase in size and speed of ships resulted in the existing maritime routes becoming narrow relative to the size of new ships. At the same time, as the improvement and optimization in marine transportation take place and the construction of structures in seas and harbor improvements pick up speed, there is an increasing probability of marine accidents. Due to these environmental changes, the need to professionally analyze the effect of marine structures on navigation arose to ensure safety of ships and a law was enacted and introduced for the Maritime Traffic Safety Audit (MTSA). In this study, a Qualitative assessment for verifying the effectiveness of MTSA was carried out with case analysis and analysis model in other similar audit scheme. It is expected that an analyzed result for effectiveness of MTSA will be a steppingstone for enhancing the MTSA and keeping maritime traffic safety as its own purpose.

The purpose of this study was to analyze the influence of self-leadership of Korean aircraft mechanics on organizational effectiveness and to investigate whether safety culture has mediating effect. The theory of leadership, which has emerged since the 1940s, has been an important and key research issue in the social sciences for the last decade and has evolved as a brand-new theory through the theory of characteristics, the theory of behavior, and the theory of situation. The new leadership theory has been extended to charismatic leadership, transformative leadership, empowerment leadership, super leadership, and self-leadership of organizational members as a new flow leadership. On the other hand, there was a precedent study on the relationship between leadership and safety culture, and this study started with interest in the relationship between self-leadership, safety culture and organizational effectiveness. As a result, safety culture has been proved to play an moderating variable in the relationship between self-leadership of Korean aircraft mechanics and organizational effectiveness. Especially, among the sub-factors of the self-leadership, self-goal setting, self-reward, and natural reward have been shown to affect organizational effectiveness in combination with the sub-factors of the safety culture, learning culture and flexible culture.

PURPOSES : This study aimed to analyze the impact the operation of pre-signals at 4-leg signalized intersections and present primary environmental factors of roads that need to be considered in the installation of pre-signals. METHODS : Shift of proportions safety effectiveness evaluation method which assesses shifts in proportions of target collision types to determine safety effectiveness was applied to analyze traffic crash by types. Also, Empirical Bayes before/after safety effectiveness evaluation method was adapted to analyze the impact pre-signal installation. Negative binomial regression was conducted to determine SPF(safety performance function). RESULTS : Pre-signals are effective in reducing the number of head on, right angle and sideswipe collisions and both the total number of personal injury crashes and severe crashes. Also, it is deemed that each factor used as an independent variable for the SPF model has strong correlation with the total number of personal injury crashes and severe crashes, and impacts general traffic crashes as a whole. CONCLUSIONS: This study suggests the following should be considered in pre-signal installation on intersections. 1) U-turns allowed in the front and rear 2) A high number of roads that connect to the intersection 3) Many right-turn traffic flows 4) Crosswalks installed in the front and rear 5) Insufficient left-turn lanes compared to left-turn traffic flows or no left-turn-only lane.
