본 연구에서는 우리나라 해기사들의 행동특성을 파악하고, 이를 통제하기 위한 방안을 제시함으로써 해양안전 문화설계를 용이하게 하고자 하였다. 한국선원 377명을 대상으로 실증분석 결과, 우리나라 선원은 일반적인 한국인의 성격특성 중 “정이 많다”는 것이 가장 뚜렷한 인식을 보였으며, 유교적 관습이 아직도 해상직업 종사자들에게도 영향을 많이 끼치는 것으로 나타났다. 그러나 직책별, 성별, 선종별 집단간에는 행동특성의 차이를 보이지 않았으나 학력별로는 차이가 있는 것으로 나타났다. 한편 한국선박의 안전운항을 위해 동원될 수 있는 수단은 한국선원의 집단 구성에 관계없이 부적 강화물을 제공하는 것보다는 정적 강화물을 제공하는 것이 도움이 될 것으로 판단된다. 선박의 안전관리 수단은 학력수준 외는 집단별 차이가 없는 것으로 나타나, 선원의 학력수준에 맞는 안전관리방안을 도입하는 것이 안전관리의 효율성을 높일 것으로 판단된다.

PURPOSES : This study is to analyze expected effect of a accident decrease when motorcycle safety inspection is introduced. METHODS : Based on the literature review of effect of 4-wheel vehicle inspection, probability of occurring accidents among defective motorcycles are calculated by using the number of estimated defective motorcycles and accidents resulting from defects of motorcycles. Then, the number of decreased accidents which is resulting from eliminating defects of motorcycles by safety inspection is estimated by using probability of occurring accidents among defective motorcycles. RESULTS : If the ratio of eliminating defects of motorcycles is 95% after motorcycle safety inspection, the effects of accident decrease of motorcycle safety inspection are analyzed from 2005 to 2008. As a result, 46,292 defective motorcycles are repaired and 1,376 accidents are prevented when the probability of occurring accidents among defective motorcycles is 2.97%. CONCLUSIONS : This study suggests the expected effect of motorcycle safety inspection is that the inspection can prevent 1,376 motorcycle accidents. However, the number of preventing motorcycle accidents are small, compared with the total number of motorcycle accidents because there are limitations to investigate the causes of defective motorcycle accidents. A more precise analysis of the expected effect of motorcycle inspection is possible when a systematic investigation of the causes of the accidents is implemented.

According to ISO 26262 (the international standard on functional safety for automotive industry), the functional safety should be considered during the whole automotive systems life cycle from the design phase throughout the production phase. In order to satisfy the standard, the automotive and related industry needs to take appropriate actions while carrying out a variety of development activities. This paper presents an approach to coping with the standard. Analyzing the standard indicates that the safety issues of the automotive systems should be handled with a system's view whereas the conventional approach to solving the issues has been practiced with focus on the component's level. The aforementioned system's view implies that the functional safety shall be incorporated in the system design from both the system's life-cycle view and the hierarchical view for the structure. In light of this, the systems engineering framework can be quite appropriate in the functional safety development and thus has been taken in this paper as a problem solving approach. Of various design issues, the analysis and verification of the safety requirements for functional safety is a key study subject of the paper. Note, in particular, that the conventional FMEA (failure mode effects analysis) and FTA (fault tree analysis) methods seem to be partly relying on the insufficient experience and knowledge of the engineers. To improve this, a systematic method is studied here and the result is applied in the design of an ABS braking system as a case study.

While the reduction of industrial accidents has been stagnant, many researchers have been studying and focusing on safety behaviors including safety perception, attitude and safety culture as a new solution as well as a turning-point of this issue. However, we do not pay attention to those studies and researches in Korean construction. Therefore, this study is to introduce preceding researches and case studies in other countries and suggest a new direction to Korean construction. This study found out the current situation and problems in Korean construction studies after tracing the safety perception, attitude and safety culture in Korea and reviewing the background and trend of overseas studies and researches with regard to safety behaviors. Fundamental researches and systematic studies must be conducted in Korean construction with the reference and research data of this study.

고속도로 이용차량대수의 증가로 고속도로의 안전 및 운영효율성을 개선하기 위한 교통류 관리전략의 필요 성이 대두되고 있다. 또한, 비, 눈, 안개 등 기상조건 악화시 통과교통량 감소, 평균속도의 저하 등 교통소통능력이 감소하고 사고 발생 개연성 및 사고심각도 증가로 인하여 운전자가 교통운영 및 안전상 적정 속도로 운행 할 수 있도록 유도할 수 있는 방안이 필요하다. 본 연구에서는 강우조건에서 고속도로에 가변제한속도를 운영시 교통안전 효과를 분석하기 위한 연구를 수행하였다. 서울-춘천고속도로에 설치된 도로기상정보시스템에서 수집된 기상정보, 루프검지기에서 수집된 교통정보를 활용하여 강우시 교통특성을 분석하였다. 분석결과, 강우강도가 증가할수록 Headway는 증가하고, 평균속도는 감소하는 특성을 나타냈다. 또한, 기존연구를 참고하여 강우시 교통특성을 대변할 수 있다고 판단되는 관련 Paramater인 Headway와 속도분포를 강우조건에서 수집된 데이터에서 추출한 값으로 조정하여 서울-춘천고속도로의 일부 구간인 분석대상 구간을 미시적 교통시뮬레이션 프로그램인 VISSIM으로 구현하였다. VISSIM COM interface를 이용하여 가변 제한속도 운영여부 및 운전자 순응도(100%, 80%, 50%)에 따른 차량 주행궤적자료를 수집하고, SSAM을 이용하여 교통안전 효과를 평가할 수 있는 SSM을 도출하여 비교분석하였다. 그 결과, 가변제한속도 적용시 미적용했을 때보다 총 상충건수가 평균 14.6건 감소하는 결과를 보였다. Rear-end의 경우 가변제한속도 적용시 평균 3.53건으로 미적용시보다 감소하는 결과를 보였으며, Lane changing의 경우에는 가변제한속도 적용시 1.2건으 로 미적용시의 10.2건보다 매우 감소하는 결과가 나타났다. 또한, 이는 운전자의 순응도가 증가할수록 교통안전 효과도 증가하였다. 강우조건에서는 비강우시보다 속도의 표준편차가 증가하는 등 교통류가 불안정해진다. 이 때 가변제한속도 적용으로 운전자의 속도선택의 자유도를 감소시킴으로써 교통류의 특성, 즉 차량간 속도의 동 질성을 높인 결과 차량간 상충이 줄어드는 결과가 나타났다. 이는 교통류관리전략에 대한 운전자의 순응도가 증가할수록 그 효과는 증가하였다.

식품안전관리는 과학적 근거에 따라 진행되어야 한다. FAO/WHO에서는 식품안전관리 4대 원칙 중 하나로 위해 성 분석을 제시하고 있으며, WTO에서는 위해성 평가에 입각한 경우에 한하여 자체적인 안전기준을 인정하고 있다. 과학적 분석 없이는 식중독 발생의 원인을 추적·제거함으로써 재발을 막는 것 또한 불가능하다. 연구개발은 과학적 근거를 생산하는 중요한 역할을 한다. 정부의 식품안전 연구개발은 11개 정부기관에서 40개가 넘는 사업을 통해 진행되고 있다. 그렇다보니 정확한 통계 자료를 확보하기 어렵다. 본 연구에서는 사업명, 과학 기술표준분류, 키워드라는 3가지 기준에 따라 국가과학기술지식정보서비스(NTIS)에서 제공하는 데이터베이스를 활용해 2008년부터 2010년까지 진행된 식품안전 연구과제를 추출하였다. 분석 결과, 식품의약품안전청과 농림수산식품부 및 농촌 진흥청의 연구사업이 중요한 비중을 차지하고 있다. 위해 성 평가를 위한 기초자료 확보 등을 위해서는 현재보다 1 년 이상 다년도 과제의 비중을 높일 필요가 있다. 또한 SCI 논문을 투고할 수 있는 수준으로 연구의 깊이를 높일 필요도 있다. 노로바이러스 등 생물학적 위해에 대한 연구 비중을 높이는 방향으로 연구 포트폴리오의 조정이 필요하다. 이를 위해서는 식품안전 관련 사업의 통합·집중화 할 필요가 있다. 별다른 차이가 없음에도 부처가 다르다보니 별도로 설정하고 있는 식품안전관리와 농축산물 위생/ 품질관리로 이원화된 과학기술표준분류의 통합도 필요하다.
