철도안전법 상의 사고 분류 이외에도 철도운영기관의 실무 차원에서 인적 오류를 유발한 당사자에게 책임이 있다고 판정할 경우 처벌과 불이익을 부과하는 책임사고 판정제도가 있다. 책임사고경험이 있는 당사자는 심리적, 신체적 피로와 긴장감을 경험하는 한편, 사고 및 장애발생의 가능성을 늘 염려하면서 주어진 과업을 수행하게 된다. 본 연구는 그 동안 철도분야 인적오류 연구의 공식적 대상에서 제외되어 왔던 철도차량 검수직 종사자를 대상으로 책임사고경험이 이례상황 스트레스 및 건강의 한가지 척도인 신체적 우울감에 미치는 인과관계를 AMOS 통해 밝혀보았다. 연구 결과, 검수직 종사자의 책임사고 경험은 이례상황 스트레스를 부분 매개로 하여 신체적 우울감에 유의한 영향을 미치는 것으로 나타났다.

This study was conducted to investigate the perception of the management of food service in schools. The subjects consisted of 271 school dietitians in the Daegu and Gyeongbuk areas. The questionnaire included the food temperature management and the frequency of the food quality confirmation. The sanitation performance of the delivery workers was evaluated with a 5-point Likert scale. The food items for which the proper temperatures while they were being received were difficult to maintain were as follows: ready-to-use vegetables, 49.8%; frozen foods, 30.3%; and fish paste, 27.7%. The frequencies of the food quality confirmation whenever the foods were received were as follows: for beef, 87.5%; pork, 84.5%; chicken, 84.1%; eggs, 73.4%; seafood, 59.4%; and processed foods, 52.8%. The total mean score of the dietitian-perceived sanitation management performance of the delivery workers was 3.86/5.00. The school dietitians said the percentage of the mixed delivery of food items in vans was 80.4%. The percentage of the dietitians who thought this mixed delivery influenced food sanitation and quality was 92.3%. Therefore, safe foods should be supplied to schools with a thorough inspection process and hygiene education, and professional research is required on the appropriate inspection process.
