Modern variety of sectors and complex operations are being made. This is industrial sites are various workers involved, and varied tasks are carried out, counselor.

Many countries have introduced new imported food safety measures, following the accident at Fukushima Daiichi Nuclear Power Station. This study was conducted to evaluate the measures contents and effects on food trades values. Eight percent of members were notified the introduced measures to the World Trade Organization. The measures’ contents were banning imports, enhancing inspection and adding certification requirement. The covered regions were some prefectures, entire Japan or all affected countries. European Union introduced a measure that subjecting foods originating from 12 prefectures to import at designated ports with required certification. The measures were amended 8 times until March 2014 to apply listed foods from 15 prefectures. The trade value of fishery products and miscellaneous foods were affected. Australia introduced a measure that required additional inspection of dairy, fishery and plants products from 13 prefectures with subsequent amendments. The trade value had no effect in tested foods. Chinese Taipei introduced a temporary import ban for all foods from 6 prefectures. Trade values for fruits were affected. The United States issued an import alert for detention without examination for listed prefectures and goods without introducing new measures. Although no specific products were affected, trade values for all foods were affected.

Universal Design involves designing products and spaces so that they can be used by the widest range of people possible. Universal Design evolved from Accessible Design, a design process that addresses the needs of people with disabilities. This paper introduces the universal design concept through analysis of causes of railway accident within the urban railway station. Railway accident analysis was performed by the internal facilities. We analyzed the standard of accident type, accident cause and accident subject such as elevator, escalator, stairs etc.

Children’s play facilities have changed over a decade from the traditional play facilities in the front yard to the new type of commercial play facilities which install more exciting and enjoyable facilities, such as Kids Park. The more diversified in the type of facilities, the more difficult in the safety management by the existing system. The ‘Safety Management System of Children’s Play Facilities’ of MOSPA(Ministry of Security and Public Administration) has provided the safety information uni-directly by government sector to the private communities. Recently, multi-directional information sharing methods, such as community mapping are adopted actively in the social activities which have common purpose for making the better community by information sharing with government and private sector. On the purpose of citizen’s participation for safe play facilities and preventing accidents, this study investigated the status of child accidents and safety standards, especially focused on the children’s play facilities. And the way for sharing safety information among the communities with the GIS mapping skills is suggested in the respect of more easily monitoring and practically inputting the comments on the status of management of play facilities by real users based on their experiences. It is expected that more activities from the private sector would participate to the safety management of children’s play facilities by realizing the suggested system.

Despite over eighty percent of industrial accidents were caused by unsafe behaviors, most safety programs still focus on changing workers’ internal status such as thinking and attitude rather than directly changing safe related behaviors. The purpose of this paper is to introduce the basic concepts and procedures of Behavior-Based Safety (BBS) which originated in applied behavior science (ABS), BBS attempts to change safety related behaviors by manipulating antecedents and consequences of workers’ behaviors. Also this paper introduces several case studies conducted globally in various industrial fields. These case studies highlight the procedures of BBS, their impacts on safety performance and accidents rate, and other business results. Based on these results, this paper proposes new guidelines for safety management.

In most child-care facilities, homeroom teachers take the responsibilities for safety education, which has been conducted in class hours on a regular basis. It was found that most homeroom teachers are lacking in teacher training opportunities, and the younger they are, the less training experience they get. Teachers with fewer teaching careers had a greater interest in safety education and training courses. In addition, homeroom teachers have been utilizing monthly toddler magazines as a method to acquire knowledges for safety education and prevention of safety accidents. The safety accidents which have most frequently occurred in care-care facilities turned out to be stumble and tear, and infants aged 3 years or younger were found to be easily exposed to the safety accidents mainly due to the frolic between peers during the free-choice activity time. The homeroom teachers recognized only traffic safety education among the range of safety training courses, which varied depending on teaching career such as traffic safety education and indoor/outdoor safety environment training, etc. In addition, it turned out that the safety training methods were limited to the utilization of discussion techniques, role-playing, description and demonstration.

지난 2011년 3월의 후쿠시마 원전 사고시 원자로 건물에서의 연쇄적인 수소폭발이 발생하였을 때 관계 자들은 제1원전 4호기의 폭발에 더욱 놀랐었는데 이는 그 당시 4호기는 정기보수를 위하여 원자로내 모 든 핵연료를 저장조에 보관중이었기 때문이다. 저장조내 냉각수 유실로 노심에서 옮겨진 핵연료가 공기 중에 노출되어 수소가 발생하고 임계가 도달하였다면 더욱 심각할 수도 있기 때문이었는데 다행히 추후 에 양호한 냉각수 상태가 확인되어 우려할 상황을 피할 수 있었다. 본 논문에서는 후쿠시마 원전 사고를 계기로 국내 원자력 발전소내 핵연료 임시 저장시설의 안전성과 관련하여 중대사고 관점에서 검토해 보 고자 한다.

In the industrial site of 21st century, there are many and various powders of material, product and fuel of coal, chemical, detergent, paint, feed and more. Therefore, there always is a possible danger of dust explosion in each and every procedure and actually, there are increasing frequency of dust explosion as the use of dust and its amount increases in processes.
