  • Training power tiller operators in safe farming is necessary to avoid farming accidents. With the continuing progress in computational technology, driving simulators have become increasingly popular for conducting such training. Purpose: The objective of this study is to develop mock control devices and data acquisition apparatus for a tiller simulator. Methods: Except for the stand and tail wheel adjusting levers, the mock control devices were developed using a tiller handle assay. The data acquisition apparatus was realized using an embedded data-logging device and LabVIEW, the system design software. Results: The control devices of a real handle assay were successfully mimicked by the mock operator control devices, which used sensors for the relevant measurements. The data from the mock devices were acquired and transmitted to the main computer at intervals of 10 ms via Wi-Fi. Conclusions: The developed mock control devices operate similar to real power tillers and can be utilized in power tiller training simulators.

  • Background: The purpose of this study was to examine undergraduate medical students' perceptions and intentions regarding patient safety during clinical clerkships. Methods: Cross-sectional and self-administered questionnaire survey was conducted on 34 students from one medical school using a modified version of the Medical Student Safety Attitudes and Professionalism Survey (MSSAPS). We assessed $4^{rd}-year$ medical students' perceptions of the cultures ('safety', 'teamwork', and 'error disclosure'), 'behavioural intentions' concerning patient safety issues and 'overall patient safety'. The overall response rate was 66.4%. Results: Among safety domains, "teamwork culture" was rated highest. "Error disclosure culture" received the lowest ratings. Regarding the error disclosure domain, only 10% of respondents reported that they have received education or training on how to disclose medical error to patients. Independent of survey domains, when students were asked "Overall, do you think your hospital is safe based on your clinical rotation?", 61.8% reported that the hospital was safe. Conclusions: Assessing students' perceptions of safety culture can provide clerkship directors and educators with information that enhances the educational environment and promotes patient safety. Discussions of medical errors, patient safety, and how best to incorporate an analysis of these issues into the existing curriculum are needed.

  • In order to improve the implementation of safety and health education at the site for industrial accident prevention activities, research was conducted to minimize inconvenience and increase utilization by redesigning and developing existing education methods. To date, occupational safety and health education has been conducted without considering the general work characteristics and functional facilities (mechanical, electrical, instrumentation, chemical) of workers (mechanical: turbine, valve, pump, hydraulic system, electrical: generator, breaker, motor, etc.). In particular, plant facilities were classified as mechanical and electrical facilities to improve the methodology for industrial safety and health education for plant maintenance workers. In addition, the "One Page Education Plan" was announced as a learning case because the spread of COVID-19 infectious diseases made it impossible to reduce or control the number of people in all groups and groups. The improvement of this training method will play a major role in improving the effectiveness of safety education in power plant workplaces.

  • Purpose: The purpose of this study lies in investigating nursing and medical staff perceptions on the importance of surgical patient safety protocol, teamwork, and patient safety culture, and how their grasp of the factors affects the degree of their performance of the protocol. Methods: A survey was conducted on 249 nurses and medical staff participating in the operating rooms of one higher general hospital in Seoul, using a 5-point scale self-reported questionnaire. Logistic regression analyses were used. Results: Operating room nurses yielded the highest scores on both the importance of the patient safety protocol and its performance. In patient safety culture, the operating medical staff yielded significantly higher scores than those of operating room nurses. Perception of the importance of the patient safety protocol and teamwork had a significant effect on the nurses' complete performance of the protocol. Conclusion: It is important to create a safety culture, where all the staff can actively and freely communicate with one another through team-based training programs. By enhancing teamwork and patient safety culture, it will be possible to establish the surgical patient safety protocol and to improve the performance of the protocol by health professionals.

  • Purpose: Purpose: The National Safety Experience Center Establishment and Reinforcement Project Management Guidelines, established to build a national safety experience center that is central to practicing education on disasters and safety accidents, requires that appropriate experience training programs be in place. However, due to the lack of classification grounds for the six areas of disaster•safety accidents presented by the Ministry of Public Administration and Security, and the mortality statistics necessary for establishing sectors have accumulated for over a decade, they are based on this. Our purpose is to standardize classification of sectors belonging to each area. Methods: We will divide disaster•safety accidents into 6 areas by three steps, and the grounds for 6 areas of accidents are presented. The 15 external causes other than the disease since 2009 has been proposed by The National Statistical Office. Therefore on the basis of these causes, various sectors belonging to each area are classified. Results: We will divide all disaster•safety accidents into six areas through three logical separation stages, and the areas were systematically classified based on the 15 factors of death. In conclusion, we present the grounds for the classification criteria in the six areas, the transportation accident disaster area in three areas, the social infrastructure system area in four areas, the crime accident disaster area in four areas, the life safety accident area in four areas, we set up all disaster•safety accidents in six areas and finally standardize total 25 areas.

  • Purpose: This study aims to compare and analysis job stress, patient safety culture, and patient safety management activities of nurses in comprehensive nursing care service wards and general wards. Methods: Through an online survey conducted on nurses with more than three months of working experience at five general hospitals in the metropolitan area, 156 participants's data were used for 𝜒2-test, t-test, ANOVA using SPSS ver. 26.0. Result: There were no significant differences in the nurses' job stress and patient safety management activities between the comprehensive nursing care service wards and general wards. However, the patient safety culture of nurses in the comprehensive nursing care service ward was significantly lower than that of general ward. Conclusion: Patient safety culture should be promoted through continuous regular patient safety education, training, and organizational support to increase patient safety management activities. Additionally, institutional programs should be prepared to reduce job stress of nurses at the frontline of patient safety.

  • Accident statistics cite the flightcrew as a primary contributor in about 70 percent of accidents involving transport category airplanes. The introduction of modem flight deck designs, which have automated many piloting tasks, has reduced or eliminated some types of flightcrew errors, but other types of errors have been introduced. To identify the impedimental factors in highly automated modem airplane cockpit systems, this study used readily available information sources and case study, From the evidence, this study identified issues that show vulnerabilities in pilot management of automation, situation awareness, communication between pilots and controllers, pilot's training and evaluation methods. The next step will require the aviation community to solve these problems for the safety improvement.

  • Objectives: This paper presents the framework and protocol design for a construction industry risk management toolbox. The construction industry needs a comprehensive, systematic approach to assess and control occupational risks. These risks span several professional health and safety disciplines, emphasized by multiple international occupational research agenda projects including: falls, electrocution, noise, silica, welding fumes, and musculoskeletal disorders. Yet, the International Social Security Association says, "whereas progress has been made in safety and health, the construction industry is still a high risk sector." Methods: Small- and medium-sized enterprises (SMEs) employ about 80% of the world's construction workers. In recent years a strategy for qualitative occupational risk management, known as Control Banding (CB) has gained international attention as a simplified approach for reducing work-related risks. CB groups hazards into stratified risk 'bands', identifying commensurate controls to reduce the level of risk and promote worker health and safety. We review these qualitative solutions-based approaches and identify strengths and weaknesses toward designing a simplified CB 'toolbox' approach for use by SMEs in construction trades. Results: This toolbox design proposal includes international input on multidisciplinary approaches for performing a qualitative risk assessment determining a risk 'band' for a given project. Risk bands are used to identify the appropriate level of training to oversee construction work, leading to commensurate and appropriate control methods to perform the work safely. Conclusion: The Construction Toolbox presents a review-generated format to harness multiple solutions-based national programs and publications for controlling construction-related risks with simplified approaches across the occupational safety, health and hygiene professions.

  • This paper aims to give an overview of the methods to inherently prevent human errors and to effectively mitigate the consequences of such errors by securing defense-in-depth during plant management through the advanced man-machine interface system (MMIS). It is needless to stress the significance of human error reduction during an accident in nuclear power plants (NPPs). Unexpected shutdowns caused by human errors not only threaten nuclear safety but also make public acceptance of nuclear power extremely lower. We have to recognize there must be the possibility of human errors occurring since humans are not essentially perfect particularly under stressful conditions. However, we have the opportunity to improve such a situation through advanced information and communication technologies on the basis of lessons learned from our experiences. As important lessons, authors explained key issues associated with automation, man-machine interface, operator support systems, and procedures. Upon this investigation, we outlined the concept and technical factors to develop advanced automation, operation and maintenance support systems, and computer-based procedures using wired/wireless technology. It should be noted that the ultimate responsibility of nuclear safety obviously belongs to humans not to machines. Therefore, safety culture including education and training, which is a kind of organizational factor, should be emphasized as well. In regard to safety culture for human error reduction, several issues that we are facing these days were described. We expect the ideas of the advanced MMIS proposed in this paper to lead in the future direction of related researches and finally supplement the safety of NPPs.

  • This study was attempted to analyze risk factors and suggest accident prevention in live line works for power transmission lines to be developed and applied in Korea. Safety problem cannot but occur at development of live line works and application to the field. With respect to this, problems likely to occur in the field among works adopting methods of works including live line works for power transmission lines were investigated and analyzed through documentary survey and risk assessment method. The results are summarized as follows. A risk assessment method model was suggested. This method enables scientific and systematic development of safety control. That is, the owner may autonomously induce safety control and build risk assessment database by work process to use them as best training data for workers. Also, in the field, it may induce all workers to participate in safety program and secure safety by making workers seek for safety working method under smooth flow from looking at risk factors to accident prevention activities. It is deemed that this humble study will prevent both accident and injury likely to occur in live line works for power transmission lines.
