The present management of the domestic and international advanced enterprises is transferring the systems and the regulations to the prevention system management. Expecially, KOSHA (Korea Occupational Safety & Health Agency) in Korea has supported to set up the OSHMS (Occupational Safety & Health Management System) by KOSHA 18001 since 1997. But small & medium enterprises (SMS) have many difficulties to set up the OSHMS because of limited natural and human resources. Therefore, this study is developed and proposed the certification standard of an OSHMS for SMS based on the case study on advanced countries, actual conditions of SMS in Korea, and opinion of specialists.

초 록 현재 우리나라는 1997년 7월부터 KOSHA18001 인증제도를 운영하여 사업장의 안전보건경영시스템 구축을 지원하고 있다. 그러나 사업장 규모에 따라 그 수준이 현저하게 차이가 있을 뿐만 아니라 안전보건경영시스템의 평가기준이 복잡하고, 어렵기 때문에 담당자들이 시스템 인식에 어려움을 겪고 있다. 특히, 중소규모 사업장은 한정된 자원과 인력으로 자율안전보건경영체제를 구축하기에는 더욱 어려움이 크다. 따라서 본 연구에서는 국내 중소규모 사업장의 자율안전보건경영체제 구축을 지원하기 위해 선진국의 안전보건경영 관련 사례와 국내 사업장의 의견을 바탕으로, 중소규모 사업장용 안전보건경영시스템 인증기준(안)을 개발하였다.

도로분류체계는 도로의 기능. 설계기준을 정의하기 위한 기초가 된다. 본 연구는 요인분석을 활용한 일반국도 유형분류에 대해 다루고 있다. 이를 위해 2004년도 상시 교통량 조사지점에서 수집된 교통자료를 이용한 요인분석을 수행함으로써 일반국도를 유형별로 분류하였다. 적용된 변수는 총 9개로 AADT(연평균 일교통량), K30(설계시간계수) D30(중방항계수), 중차량 비율, 주간 교통량 비율, 첨두율, 일요일 계수, 휴가철 계수, 그리고 COV(변동계수)이다. 요인분석 결과, 교통량 변동 특성 요인과 중차량 및 방향별 특성요인이 추출되었다. 군집분석 결과 전체 353개 상시지점이 3개의 그룹으로 분류되었으며 그룹 I은 관광부도로, 그룹 II는 지방부도로, 그룹 III은 도시부도로로 판단된다.

This study conducted the questionnaire on present condition of certification, background, purpose, effect and promotion of an occupational health & safety management system which introduced in domestic from 1999'. The questionnaire was conducted with 136 companies which replied in questionnaire distributed to 193 companies which received the certification. Also, recognition improvement of managers and participation of workers are demanded, the support to subcontract companies is demanded because the disaster prevention effect of the companies which possess the support program on subcontract companies is good, and reduction in the insurance rate to companies which received certification is demanded to activate an occupational health & safety management system.

This study was intended to help workplaces set up an occupational health & safety management system by investigating the certification of the system and by conducting a questionnaire to survey the necessity, purpose, effect and promotion of the system. The occupational health & safety management systems generally adopted in Korea are OHSAS 18001 and K-OHSMS 18001, which are the PDCA model, such like the quality and environment management system. Because these standards have a compatibility with other management systems, individual or integral certification is available. A telephone questionnaire was conducted with 30 workplaces in Kyeonggi Province and Incheon Metropolitan City, which have been certified for the occupational health & safety management systems (OHSAS 18001, KOSHA 2000, and/or K -OHSMS 18001). About 92 percent of them were large-sized workplaces with over 500 employees. For the question on the necessity of the system, most of the respondent answered very necessary. The purposes of the certification were to control the risks in safety and health, to have a systematic approach for accident prevention and sustainable improvement, and to comply with a range of regulations voluntarily, in that order. Most of the answers to the question on the effect of the system were prevention of accident. For the question on the promotion of the system, the most prominent answer was reduction in the workers compensation rate.

This study deals with the application of knowledge-based engineering and a methodology for the assessment & measurement of reliability, availability, maintainability, and safety of industrial systems using fault-tree representation. A fuzzy methodology for fault-tree evaluation seems to be an alternative solution to overcome the drawbacks of the conventional approach. To improve the quality of results, the membership functions must be approximated based on heuristic considerations. Conventionally, it is not always easy to obtain a system reliability for components with different individual failure probability density functions(p.d.f.), We utilize fuzzy set theory to solve the adequacy of the conventional probability in accounting and processing of built-in uncertainties in the probabilistic data. The purpose of this study is to propose the framework of knowledge-based engineering through integrating the various sources of knowledge involved in a FTA.
