This research chose 135 environmental cleaners in Busan Metropolitan City as subjects. First, the reality of wearing their safety jackets was investigated. Next, visual evaluation of the reflexive function of the current safety jackets was made. Then, based on the above results and the subsequent improvement proposal, the final product, the research costume, was made. 1. Based on the investigation of the wearing reality of safety jackets and the visual evaluation results of the reflexive function, an improvement proposal was made. As cleaners are usually seen sidewise on the roads and lateral luminosity is rather low, this aspect was compensated on the part of a jacket. Also, the reflexive belt used the diagram of ${\Delta}$ to improve visual effects. 2. As the lower body held the accident frequency of 45.0%, the sides of pants had the reflexive belt to increase visibility. 3. In consideration of the mutual effects between the background cloth and general reflexive width, the same width (5cm) of the reflexive belt as that of Type A was adopted.

Reviews indicated that supervisory feedback provided to workers is the most effective intervention to change performance in organizational settings. However, supervisors themselves hardly receive feedback on their own behaviors. This study implemented self-management technique to improve supervisory behaviors at a construction site. Self-management in the current study consisted of goal setting, self-monitoring and providing reinforcers for two supervisory behaviors; (1) conducting safety observations and (2) interacting with workers for safety improvement. Two supervisors severed as participants. An AB within-group design was adopted. After baseline (A), self-management technique was implemented (B). Results suggested that self-management was effective in increasing the two supervisory behaviors. Moreover, the increased supervisory behaviors were associated with improvement in workers' safety performance.

Interface control activities during the nuclear power plant (NPP) construction and operation have been reviewed for enhancing the safety of NPP. The primary focus of the study is given on analysis of lessons learned from the recent significant events of Korean Standard Nuclear Power plant (KSNP), such as a series of break-off of thermal sleeves at YGN 5 & 6 and radioactivity leak at YGN 5, in respect of interface control. Based on the results of the analysis, this study recommends measures for the improvement of interface control among utility and technical supporting organizations (TSO), and suggests new regulatory systems, such as reporting of safety significant non-conformances, to effectively verify the adequacy of interface control activities during construction and operation of NPPs.

Based on data from the Korean Academy for Dental Administration, which has been conducting the Dental Quality Improvement (QI) Contest since 2010, we aimed to provide basic data for the development of dental quality improvement indicators by analyzing the trends of dental quality improvement activities. A total of 54 articles in the dental QI contest from 2015 to 2021 were used to search for frequently used words and to classify the quality of dental care. The criteria for the quality dimension of dental care were first classified into structure, process, and outcome, and secondary classification was performed into patient safety, timeliness, patient-centeredness, equity, efficiency, effectiveness, and accessibility. The frequently used key terms were satisfaction (five times), efficiency (four times), system (three times), and implant (three times). The activities for process evaluation were high at 62.26%, structural evaluation activities at 35.85%, and outcome evaluation activities at 1.89%. According to the components of dental care quality improvement, the activity performed under efficiency was the highest (33.96%), followed by patient-centeredness (18.87%), effectiveness (16.98%), patient safety (15.09%), accessibility (5.66%), timeliness (1.89%), and the equity (1.89%). QI activities in dental hospitals were mainly activities on improvement in structure and process, as well as activities on efficiency, patient-centeredness, effectiveness, and patient safety.

Efforts to reduce on-site safety incidents have expanded, leading to active research in this domain. However, a systematic analysis to improve the utility of technology is lacking. In this study, we conducted a survey on the various institutional and technical improvement measures to promote the application of smart construction safety technology over three years after the implementation of the "Smart Safety Equipment Support Project." The results showed that financial constraint was the primary obstacle in the adoption of this innovation. Fostering a flexible environment in the utilization of management fees and financial support of projects was determined to aid in the extensive application of the technology. Ensuring cost efficiency and user-friendliness were principally necessary for technical enhancements in the smart construction safety technology. Technologies, such as VR/AR safety education, real-time location tracking, wearable devices, and innovation on streamlining safety-related work efficiency, had been anticipated to contribute to on-site safety. Operating a smart safety control center was expected to be beneficial in the systematic securing of data and reduction of safety blind spots. Effective methods had been suggested to overcome the barriers that hindered the development and application of smart construction safety technology. This study facilitates in the technological improvements in this field.

Avionics electronic equipment refers to the electronic equipment installed on an aircraft. Failure of avionics equipment can have a significant impact on aircraft operations as well as threaten the safety of pilots and passengers. Therefore, avionics electronic equipment is required to have higher reliability and safety than electronic equipment used for other purposes. Avionics equipment must consider various component selection and system design to meet reliability and safety-related requirements from the initial design stage. In this paper, we describe safety, reliability performance analysis method of avionics equipment, and introduce various design improvement methods that can be performed to meet safety requirement performance. Finally, the safety performance of the improved avionics equipment was reanalyzed and compared with the value before the improvement, the validity of the proposed design change was verified.

Generally speaking, the demolition works is the subsequent construction activity which has been done after building life-span of twenty two years or so. However, it was not prepared suitable systems and laws and regulations as long-term solutions. In this study, it was suggested the improvement guideline of safety management-related laws in domestic demolition works. The three improvement of laws was suggested as follows. ${\bullet}$ First, it was suggested proposals for demolition works standards in safety management plan of management law for construction activity. ${\bullet}$ Secondly, it was provided improvements for standard safety work guide of demolition works of industrial safety and health law. ${\bullet}$ Third, it was proposed integration method of redundancy in safety management plan and risk assessment regulations.

Recently, the fatality rate in the construction industry has not decreased any more and is in a stagnant state, and there are efforts by various construction participants such as ordering, design, and construction, management to improve it. In order to reduce serious accidents in the construction industry, which is higher than in other industries, the government evaluates the safety level of construction participants and announces it to raise awareness. However, in the items, standards, and procedures of the safety management level evaluation, there are points that do not match the site situation, and it is necessary to improve them. In this study, in order to improve the safety management level evaluation for construction technology service providers who are in the worst situation for safety management, the safety management level evaluation result analysis and Focus-Group-Interview(FGI) were conducted. improvement direction was suggested.
