Since most construction workers comprehend information on work through sight, the importance of safety signs are increasing by the day. In Korea, due to the sharp economic progress and the higher standard of the workforce, since the end of 1980, each year the number of foreign workers entering the country who working simple technical jobs have increased this condition. This study researched safety signs, which are the final accident prevention measures at the workplace. Based on the study, comprehension of the standard safety signs of the Occupational Safety and Health Act (OSHA) was lacking at a level of 2.5. Also, the perception level of the Industry Public Safety Law (38%) was very low. And, it was found that sex and experience or non-experience in safety training was not an issue in the level of understanding. However, when satisfying the standards of the Occupational Safety and Health Act and changing the safety signs, the level of understanding went up to 3.49 and the perception level was increased significantly to 70%. Thus, it is concluded that, since the foreign workers are mainly from non-English speaking countries and because the workers of Korea are not familiar with English, in order to provide proper safety information, there must first of all be simplistic and concise pictograms. This will provide needed information and must be coupled with simple English words that can give additional information to the worker and be effective in helping him understand and perceive the safety sign. Also, it has been determined that the existing forms of safety signs and their effectiveness in industry accident prevention must be reassessed.

With the development of society, the scale of the statute is not only increasing, but also the content is getting complicated. The scale of safety standards existing in the law is also increasing and specialized, making it difficult to integrate and manage to minimize conflicts or overlaps among safety standards. For the integrated management of safety standards, a technology that searches for and extracts safety standards in laws and regulations must first be secured. In this study, considering the limitations of time and manpower, a tool for automatic detection of safety standards is developed based on several specific cases. The safety standards classified in the previous studies and the safety standards announced by the Ministry of Interior and Safety were analyzed, and also statute information which includes safety standards extracted by the National Disaster Management Institute in 2018 was collected. After the collected laws were refined and morphological analysis was performed, a safety standard thesaurus was constructed and indexed to develop a safety standard search tool. When automatic search tools are routinely applied to find safety standards in the future, it is expected that these tools will help to solve overlapping or conflicting problems of complex safety standards.

Objectives : We intended to evaluate the double standard status and to identify factors of determining double standard criteria in multinational corporations of Korea, and specifically those in the occupational health and safety area. Methods : A postal questionnaire had been sent, between August 2002 and September 2002, to multinational corporations in Korea. A double standard company was defined as those who answered in more than one item as adopting a different standard among the five items regarding double standard identification. By comparing double standard companies with equivalent standard companies, determinants for double standards were then identified using logistic regression analysis. Results : Of multinational corporations, 45.1% had adopted a double standard. Based on the question naire's scale level, the factor of 'characteristic and size of multinational corporation' was found to have the most potent impact on increasing double standard risk. On the variable level, factors of 'number of affiliated companies' and 'existence of an auditing system with the parent company' showed a strong negative impact on double standard risk. Conclusion : Our study suggests that a distinctive approach is needed to manage the occupational safety and health for multinational corporations. This approach should be focused on the specific level of a corporation, not on a country level.

Assessing the stability of small fishing vessels is important to prevent capsize accidents in coastal waters that primarily occur on small fishing vessels. However, the regulations regarding stability assessment for small vessels under 24 m are inadequate according to the domestic Fisheries Act. Based on safety standards issued by the Ministry of Oceans and Fisheries in 2022 to enhance safety and welfare, vessels adhering to the enhanced safety standards for standard ship types are required to establish stability regardless of their length. This study aims to utilize these aforementioned standards to assess the stability of vessels under 24 m, investigating the suitability of applying these criteria to these vessels and examining the impact on various small vessels with different superstructures. Initially, a 4.99-ton fishing vessel designed according to the standard ship type was selected as the subject vessel. Compliance with the standards was evaluated based on the initial stability of the vessel using the transverse metacentric height (GM) and transverse restoring moment arm at the limit angle (GZ_α). Additionally, six types of small vessels with identical hull forms and specifications to the subject vessel were further examined using prevalent superstructure designs in small fishing vessels. The stability of the subject small vessel was also assessed. A study of a 4.99-ton standard fishing vessel confirmed that the safety standards for standard fishing vessels with enhanced safety welfare were applicable to small fishing vessels under 4.99-ton class and that the stability of small fishing vessels with superstructure modifications was not significantly changed.
