  • Purpose:The purpose of the paper is to review the problems of performance enhancement of safety certification standards and to suggest directions for improvement in order to rationalize safety certification standards for future industrial development and environmental changes. Method: The problems and limitations of the safety certification system are summarized through literature review and interview with manager, and the status of safety certification standards is classified into design standards, performance standards, and detailed standards, and the status analysis is performed. In addition, by synthesizing the results of the investigation and analysis, improvements are suggested to improve the performance of the safety certification standards. Result: Through the survey, the problems and limitations of safety certification could be grouped into six categories: government-led certification system operation, standardized certification standards, long time required to improve certification, poor certification standards preparation system, and lack of reflection of industry opinions. And, as a result of analyzing the certification standards by dividing them into performance and design standards, in the case of machinery, equipment, and protection devices, the design standards were high at 69.7% and 64.9%, whereas in the case of protective equipment, the performance standards were high at 61.1%. In order to improve the performance of safety certification standards centered on design standards, it is necessary to determine the possibility of performance enhancement of the certification standards and determine the feasibility of the inspection test method. In order to improve performance, it was reviewed that it was necessary to establish a systemic foundation and infrastructure, such as strengthening the Product Liability Act, systematizing market monitoring, etc., distributing certification test tasks, and participating in the preparation of certification standards by the private sector. Conclusion: Through this study, the problems and limitations of Korea's safety certification system were summarized and the necessity for performance improvement was reviewed. Performance improvement of safety certification standards is a matter that requires preparatory work, such as legislative revision and infrastructure construction, and requires mid-to-long-term promotion. In addition, rather than improving the overall safety certification standards, the performance requirements for each item subject to certification should be reviewed and promoted, and details should be specified through additional research.

  • 본 연구의 목적은 STS 304 프로펠러축의 육성가공 및 STS 630 프로펠러축의 열 가공에 따른 강도 및 내식성 등의 재질특성변화 등을 조사 분석하여 선박기관기준 제8조 제2항에서 규정하고 있는 ‘용접수리 불가’에 대한 근거자료 제시(동조동항의 단서조항에 대해서는 일반적으로 알려진 스테인리스강의 용접에 대한 적정방법 이외에 연구결과를 바탕으로 적정 기준을 제시할 수 있는지에 대한 부분도 동시에 검토 하고자 함)는 물론, 선박기관기준 제65조 제1호(총 톤수 20톤 이상의 경우는 제59조 제1항 적용)에서 규정하고 있는 석출경화계 스테인리스강의 제1종축으로써의 인정 여부에 대한 유효성을 제시하여 프로펠러축의 가공(육성․열)과정에 필요한 기본 방향을 제시하고자 함. 따라서 본 연구에서는 STS 304, STS 630 프로펠러축의 가공에 따른 결과를 바탕 으로 위에서 언급한 사항들에 대한 근거자료 확보 및 프로펠러축의 가공에 따른 방향을 제시하기 위한 일환으로 ‘스테인리스강 프로펠러축의 가공에 따른 재질 특성에 관한 연구’를 실시함으로써 프로펠러축 검사와 관련한 평가 기준 정립의 근본적인 지침 자료를제시하고자 함. 또한 본 연구과제는 스테인리스강 프로펠러축에 대한 가공(육성․열) 특성을 살펴 봄으로써 기존에 이미 발표된 판 형태의 스테인리스강 용접에 대한 연구와는 다소 구별되는 과제일 뿐만 아니라 단순한 스테인리스강의 용접특징을 나타낸 실험들과는 다르게 스테인리스강 프로펠러축에 대한 특징들을 분석하고 평가함으로써 현장중심의 연구가 될 수 있도록 하였음. 이번 연구의 결과는 일반적으로 알려진 스테인리스강의 용접관련 특성들을 통해어느 정도의 결과 추정은 가능하나 앞에서 언급한 기준들에 대한 구체적인 근거자료를 확보하여 필요시 적절하게 활용할 수 있는 자료가 될 수 있도록 하고자 하였음.

  • The objective of this study is to present the inspection standards of motorcycle brake system affecting motorcycle traffic accident. The inspection standards of motorcycle brake system recommended by CITA (International Motor Vehicle Inspection Committee) are studied. The brake performance for preventing the traffic accident is assessed by the brake efficiency. Considering the KMVSS (Korean Motor Vehicle Safety Standards) and the inspection standards of CITA, United Kingdom and Japan, the brake performance in the inspection standards of motorcycle is suggested. It is recommended that the efficiency of independent front and rear brakes are 40% and 27%, respectively. It is recommended that the efficiency of combined front and rear brakes is 50%.

  • This research was performed to investigate chemical and microbiological hazards of Ready-to-eat(RTE) compound foods which uses the by-product of meat. For this experiment, 51 samples of RTE compound foods in by-product of meat distributed in Incheon from January to December 2006 were tested. The contents of heavy metals in the main ingredient of RTE compound foods were in the range of $0.073{\sim}0.112ppm$ for lead (Pb), $0.006{\sim}0.013ppm$ for cadmium (Cd) and $0.746{\sim}0.978ppb$ for mercury (Hg). The concentrations of residual ABS(alkyl benzene sulfate) in the small intestine which is a main ingredient of Gopchang-casserole were $$0.8ppm{\sim}57.6ppm$ (Ave. 10.3ppm). Staphylococcus aureus was isolated from 11 samples (21.6%) among 51 main ingredients of RTE compound foods. The isolation rates of Salmonella spp. and Clostridium perfringens were 2.0% (1/51) and 5.9% (2/51), respectively. By types of main ingredient, the small intestine was showed the highest isolation rate as 35.3% (12/34), ham and the sausage which are main ingredients of the Budae-pot stew were 25% (2/8) and other meat products were 20% (1/5). Food poisoning bacteria was not found in the blood of pig which is a main ingredient of the Sunji-pot stew. 28.4% (27/95) of sauce included in each RTE compound foods were coliform bacteria positive. Pesticide residues were found in four of 45 vegetables which are the additional ingredient of RTE compound foods. The concentrations of pesticide were chlorothalonil 2.8 ppm, EPN 10.3 ppm, chlorpyrifos 0.4ppm and indoxacarb 0.7ppm. In 33 bean sprout samples, captan and carbendazim were not detected.

  • The paper is aiming at presenting the proper treatment method and procedures of ILW waste to both waste generators and acceptor so that the waste characteristics are satisfied with the WAC(Waste Acceptance Criteria) and as a result, the disposal facility would be operating safely. The ILW generators are responsible for reducing the volume of waste, treating and packaging the waste in order to meet the WAC, and acceptor has an obligation of inspecting the waste in conformity with the acceptance procedure established by regulation. Recently, a number of countries including France and USA examine the disposal acceptability of ILW waste by the WCP(Waste Package Quality Certification Program).

  • Recently, an important physical device of transportation, such as car, railroad, ship and aircraft has changed into electronic control unit. According to accident reports, the most of car accidents are caused by faults of embedded software loaded to computer control unit. The facts implies that the test to find defects in embedded software haven't performed sufficiently. As a result, it is necessary to establish the test procedures of embedded software based on safety assessment criteria. The objective of this proposal is to provide a unit test procedure complied with the safety assessment criteria for the embedded software. In addition, an effective unit testing procedure and defect analysis methods are proposed and a testing procedure using a safety criteria built-in tool is presented.
