  • Given the inadequate regulatory framework for liquefied hydrogen gas storage tanks on ships and the limitations of the IGC Code, designed for liquefied natural gas, this study introduces a critical assessment procedure to ensure the safety and suitability of such tank designs. This study performed a heat transfer analysis for boil-off gas (BOG) calculations and established separate design load cases to evaluate the yielding and buckling strength. In addition, the study assessed methodologies for both high-cycle and low-cycle fatigue assessments, complemented by comprehensive structural integrity evaluations using finite element analysis. A comprehensive approach was developed to assess the structural integrity of Type C tanks by conducting crack propagation analysis and comparing these results with the IGC Code criteria. The practicality and efficacy of these methods were validated through their application on a 23K-class liquefied hydrogen carrier at the concept design stage. These findings may have important implications for enhancing safety standards and regulatory policies.

  • On July 31, 2008, the Government issued the construction and operation permit for the first low and intermediate level radioactive waste disposal facility in the Republic of Korea. In this paper, the fundamental regulatory framework, regulatory requirements and technical standards of the disposal facility are introduced, and the phased review process adopted for evaluation of the safety of the facility is briefly described. The Atomic Energy Act sets forth a stepwise regulatory framework for the whole life-cycle of the disposal facility such as siting, design, construction, operation, closure and institutional control. More detailed regulatory requirements and technical standards are stipulated in the subsequent regulations of the Atomic Energy Act and a series of Notices issued by the Ministry of Eduction, Science and Technology. The Korea Institute of Nuclear Safety, as entrusted by the Ministry under the Atomic Energy Act, conducted safety review on the disposal facility, and evaluated the compliance with relevant criteria in all technical elements(i.e. siting and structural safety, radiological environmental impact, operational safety, systems and components, quality assurance, and total systematic performance assessment, etc.). The overall safety review process can be phased into inception phase, initial review phase, main review phase and completion phase. The review results were reported to and deliberated by the five Sub-committees of the Special Committee on Nuclear Safety, and then reported to the Ministry. The Ministry issued the construction and operation permit of the disposal facility through the deliberation of the review results by the Nuclear Safety Commission. Hereafter, the safety of the repository will be reassured by a series of subsequent regulatory inspections and reviews under the Atomic Energy Act. In addition, the licensee's continuous implementation of the "Safety Promotion Plan" may also enhance the long-term safety of the repository and contribute to build-up the confidence of the safety case.

  • The aim of this study is to propose suggestions for establishing Korean regulatory standards of infant formula. Accordingly, the regulatory standards for food contaminants and additives in Korean infant formulas were compared and analyzed with those in CODEX, EU, Australia and New Zealand. Several suggestions for regulations were found from different countries. Firstly, it is advisable that additives for nutrient supplement of infant formula be classified as types of nutrients. Secondly, it is proposed that guidelines should be set on the maximum amount of additives in infant formula. Thirdly, pathogens such as Staphylococci and Salmonella of infant formula should be regulated. Finally, present regulations need to establish the maximum permissible levels of some pesticides, Pb and Al, that other countries are already regulating. These proposed recommendations would broaden the scope of infant formula regulatory standards needed for infants' health.

  • Background: Work-related stress is one of the major causes of occupational ill health. In line with the regulatory framework on occupational health and safety (OSH), adequate models for assessing and managing risk need to be identified so as to minimize the impact of this stress not only on workers' health, but also on productivity. Methods: After close analysis of the Italian and European reference regulatory framework and workrelated stress assessment and management models used in some European countries, we adopted the UK Health and Safety Executive's (HSE) Management Standards (MS) approach, adapting it to the Italian context in order to provide a suitable methodological proposal for Italy. Results: We have developed a work-related stress risk assessment strategy, meeting regulatory requirements, now available on a specific web platform that includes software, tutorials, and other tools to assist companies in their assessments. Conclusion: This methodological proposal is new on the Italian work-related stress risk assessment scene. Besides providing an evaluation approach using scientifically validated instruments, it ensures the active participation of occupational health professionals in each company. The assessment tools provided enable companies not only to comply with the law, but also to contribute to a database for monitoring and assessment and give access to a reserved area for data analysis and comparisons.

  • Recently, there has been an increasing interest in the regulation of medical & dental profession in South Korea due to various medical scandals & exacerbated commercialism. Consequently, the voice asking for strengthening the license management of medical & dental profession is rising. However, there is an absolutely lacking discussion on self-regulation of the Korean dentist community. This study investigated International Society of Dental Regulators and dental regulatory authorities in the U.K., Ontario in Canada, California in the U.S. and Australia. In addition, this study examined what situations Japan was in, which was similar to Korea in terms of systems. In the U.K., the U.S., Canada and Australia, there are independent dental regulatory authorities, which place emphasis on lay personnel participation. In addition, the organizations prepared very specific and detailed ethics, standards, and punishment guidelines to be followed by professionals. And, various efforts are being made to secure transparency and trust. As a result of this study, self-regulation in Korea seems to require an open approach that embraces civil society, and it is considered that dentist should lead social discussion more positively.

  • The impediment in enhancing the ship safety and combating vessel-source marine pollution depends on the combination of the immediate and mediate factors. The former is mainly caused by human errors and failure in compliance with the international convention standards in operation of compliance with the international convention standards in operation of vessel. The latter by the attitudes and activities of some of the flay states taking little responsibilities with appropriate seriousness in policing their fleets due to the lack of implementing capability of adminstrations. So long as there exists a large size of variation in implementing capability of administration between flag states a globally remarked progress cannot expect to be made in assuring the ship safety and preventing the vessel-source pollution Therefore a new regulatory regime is suggested to be adopted by IMO to maintain high standard flag state adminstrations by recommending standard paradigm to member states so that the development of a implementing culture is encouraged and supported.

  • Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.

  • Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.
