  • The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.

  • Paralytic shellfish poisoning (PSP) occurs when saxitoxin (STX), which is produced by harmful algae (dinoflagellates) and then accumulated in bivalve shellfish by filter-feeding, is consumed by humans. With recent advances in analysis technology, it has been reported that dinoflagellates also produce a variety of analogues such as the gonyautoxin (GTX) group and the N-sulfo-carbamoyl toxin (C toxin) group, in addition to STX. Accordingly, CODEX and the EFSA are stepping forward to manage STX and analogues as STX groups requiring safety management. In Korea, the occurrence of dinoflagellates producing STX analogues has already been reported, and contamination of analogues (GTX group, C toxin group) in live mussels has also been reported. In this study, in order to provide the basis for systematic monitoring and safety management of STX and analogues, their physicochemical characteristics, occurrence of dinoflagellates, toxicity and toxic equivalency factor, analytical method and occurrence were widely reviewed. This review is expected to contribute to strengthening the safety management of STX and its analogues.

  • This study compared, analyzed, and verified the accident rate and accident fatality rate (per 10,000 workers) of workplaces that perform safety management on behalf of a safety management institutions designated and registered in accordance with the OSHAct and workplaces that perform safety management. According to the research results, the significance was confirmed that the group with a low accident rate was the workplaces that self-appointed safety managers, workplaces with self-appointed safety managers in size with less than 300 employees, and workplaces in the industrial accident insurance industry in the manufacturing and transportation, warehouse, and telecommunications industries. The groups with a low accidental death rate were workplaces with less than 300 employees, workplaces where safety management was performed on behalf of safety management institutions, and workplaces with selfappointment for other medical businesses. In this study, it was confirmed that the accident rate in the safety management agency's workplaces was higher than that of its own appointed workplaces, and that there were some differences in the accident fatality rate depending on the size and industry. Therefore, since the current safety management agency system cannot ensure the effect of preventing accidental deaths, there is a need for comprehensive improvement of the agency system and improvement of the system to strengthen expertise in preventing industrial accidents.

  • This study investigated the recognition difference among construction work participants for the assignment of the safety and health management responsibility to a client by survey. Recently, there were some studies for the client's responsibility and duty and they suggested the client-initiative safety and health management system in order to prevent construction accidents. To supplement the existed studies, this study surveyed various construction participants such as clients, safety managers, construction managers, supervisors, others. The clients and construction managers considered the contractor as most important person to prevent construction accidents, but the safety managers and supervisors considered the client. For the opinion that the assignment of the safety and health management duty to a client is helpful, safety managers were agreed with the most. However, the clients showed the lowest agreement. The reasons that the negative opinion for the assignment of client's the safety and health management were different between clients and other construction parties. Since, clients showed large difference to other construction participants for the recognition of works' safety and health, the education about the works' safety and health management should be continuously performed for clients to have correct recognition for works' safety and health.

  • The increasing size and complexity of modern construction projects demands mature capabilities of onsite personnel with regard to recognizing unsafe situations. Construction safety training is paper or computer-based and suffers from a distinct gap between the classroom training environment and real-world construction sites; even trained personnel can find it difficult to recognize many of the potential safety hazards at their jobsites even after receiving construction safety training. Immersive technologies can overcome the current limitations in construction safety training by reducing the gap between the classroom and a real construction environment. This research developed and tested a new Augmented Reality (AR)-based assessment tool to evaluate the hazard recognition skills of students majoring in construction management as part of a construction safety course. The quantitative and qualitative results of this research confirmed that AR-based assessment can become a very effective assessment tool to evaluate safety knowledge and skills in a construction safety course, outperforming both paper and computer-based assessment methods. The students preferred AR-based assessment because it provides a realistic visual context for real world safety hazards.
