        Natural radionuclides-containing substances (NORM) contain natural radionuclides and cause radiation exposure. In Korea, safety management measures were needed to deal with and dispose of radon mattresses containing monazite in relation to such NORM. However, there is no clear safety management system related to NORM waste in Korea. In order to manage this reasonably and systematically, it is necessary to investigate and analyze standards and management measures related to the treatment and disposal of NORM waste. Therefore, this study investigated and analyzed the exemption and clearance level of NORM waste regulations in international organizations and foreign countries. IAEA GSR Part 3, 2013/59/Euratom, ANSI/HPS N13.53, CRCPD SSRCR Part N, and ARPANSA Publications 15 safety management regulations were analyzed to investigate safety management standards for NORM waste. The exemption and clearance level in international organizations and foreign countries were compared and analyzed based on radioactive concentration and dose. In addition, the management measures proposed for each literature were also investigated. As a result of the analysis, IAEA GSR Part 3 applied 1 mSv as a regulatory exemption level, 1 Bq/g for uranium and thorium series as a clearance level, and 10 Bq/g for K-40 nuclides. The IAEA recommends a differential approach to the potential and scale of exposure. The EU applied 1 Bq/g to uranium and thorium families and 10 Bq/g to K-40 nuclides for both regulatory exemption and clearance levels. The EU recommended that it be managed in proportion to the scale and likelihood of exposure as a result of the action. It is analyzed that this is similar to the IAEA’s management plan. In the United States, there was no single federal government radioactive concentration and dose for NORM management. The management plan differed in management status and level from state to state, and K-40 was excluded from regulation unless it was intentionally enriched. In the case of Australia, the radioactive concentration of uranium and thorium was 1 Bq/g as a standard for regulatory exemption and 1 mSv as a dose. As a management plan, it was suggested to dispose of waste by means of accumulation, dilution/dispersion, and reclamation. It was also suggested that the scale of exposure, like international organizations, take into account the possibility. The results of this study are believed to be used as basic data for presenting domestic NORM waste treatment and disposal methods in the future.

        지방관리 무역항은 비교적 중소형 무역항으로 지방도시의 경제력 강화 및 지역 산업 부가가치 제고를 위해 활발한 운영이 필요 하다. 또한, 선박대형화가 이루어지고 있는 국제적 흐름에서 지방관리 무역항의 효율성 증대를 위해 항만기본계획상 기존 선석규모 대비 대형선박의 접안이 필요하며, 부두 및 선박의 안전성 확보를 위해 대형선박 접안시 계류시설 확충 및 안전운용기준 마련이 필요하다. 본 연구에서는 지방관리 무역항 중 옥계항을 선정하여, 현행 2만 DWT급 부두에 5만 DWT급 선박이 계류시 시나리오에 따른 계류안전성 평 가를 수행하였다. 평가 결과, 대상 부두에 100톤급 계선주를 신설하였을 경우, 긴급이안기준은 기존 파주기 3.2초에서 풍속 27노트, 파주기 5.0초에서 풍속 22노트의 계류 한계 조건이 파주기 3.2초에서 풍속 41노트, 파주기 5.0초에서 풍속 36노트로 약 50 % 정도 증가하는 것으로 분석되었다. 본 연구 결과는 지방관리 무역항에 기존 선석규모 대비 대형선박 접안시 부두 계류시설의 안전성 강화와 안전운용기준 설정 을 위한 기초 자료로 활용될 수 있다.

        In the recent business environment, risks related to product safety problems are increasing. These are arising from various factors such as increasing product and production complexity, supply chain diversification, enhanced PL (product liability) law and strengthening regulations of the government. Accordingly, ISO (international organization for standardization) published standards of PSMS (product safety management system) for suppliers such as ISO 10377 and ISO 10393. Meanwhile, the ISO 9001 QMS (quality management system) was revised in 2015, and it has established itself as an effective tool that can consistently meet the various requirements of stakeholders and promote customer satisfaction. This study aims to suggest an integration framework of QMS and PSMS based on the recent ISO international standards. To this end, firstly, the relationship between QMS and PSMS is studied based on the quality and product safety definitions, PDCA (plan-do-check-act) cycle and risk-based thinking. Secondly, the requirements of ISO 10377 and ISO 9001 are compared and classified as the common and ISO 10377 specific requirements. Finally, integration steps of two systems are suggested and guidelines that can systemize the integrated requirements are presented in the aspect of processes and documentation. This study is expected to be used as a guideline that helps companies those have already acquired QMS certification to build an international-level product safety management system early.

        The ISO 9000 Quality Management System(QMS) standard is an effective tool that can consistently meet the various requirements of stakeholders and promote customer satisfaction management. However, in the recent business environment, not only quality issues but also risks in various other areas are increasing. In particular, risks related to product safety problems which are arised from product convergence, diversification of methods of production and globalization of supply chain pose a great threat to the sustainability of companies. Accordingly, ISO published standards of Product Safety Management System(PSMS) for suppliers such as ISO 10377 and ISO 10393. This study aims to suggest an integration framework of QMS and PSMS based on ISO international standards. To this end, the relationship of QMS and PSMS are analyzed and the requirements of the both systems are integrated based on the Plan-Do-Check-Act(PDCA) cycle and risk-based thinking. In addition, guidelines that can systemize the integrated requirements are presented in the aspect of processes and documentation. This study is expected to be used as a guideline that helps companies that have already acquired QMS certification to build an international level product safety management system early.

        본 연구는 연안여객선사의 안전관리 운영 효율성을 분석하기 위한 기초연구로 적절한 안전경영지표 평가항목을 설계하고 연안여객선 사를 대상으로 평가항목의 유효성을 검증하는데 목적이 있다. 이를 위해 먼저 연안여객운송사업자의 안전관리책임자, 공무원(선박검사관), 여객 선 운항관리자 등으로 구성된 전문가 그룹을 통해 연안여객선사의 자발적 안전관리 활동을 평가하기 위한 5개의 평가항목과 14개의 세부 평가요 인을 선정하고 사전검증 및 테스트를 통해 객관성을 제고하였다. 이 안전경영지표 평가항목을 이용하여 44개 연안여객선사에 대한 자발적 안전 관리 수준을 평가하였다. 그리고 평가항목의 유효성을 검증하기 위하여 안전경영지표 평가항목 결과와 중대해양사고 비율을 비교분석하여 평가 항목의 타당성을 확인하였다. 이를 통해 자발적 안전경영 수준이 높은 업체일수록 중대해양사고가 발생하지 않고 자발적 안전관리에 무관심하거 나 소홀한 업체는 상대적으로 높은 중대해양사고가 발생하고 있는 것을 알 수 있었다. 이처럼 안전경영지표 평가항목 선정을 통해 연안여객선사 의 안전관리 운영 효율성을 분석하는데 중요한 항목을 객관적인 관점에서 도출하였다. 따라서 향후 안전관리 효율성 분석을 위한 기초자료로 활 용될 수 있을 것이다.
