연구개발 활동의 다양화와 융합화에 따라 실험실에서 다양한 종류의 화학물질의 취급 사용과 함께 연구실의 수행업무도 복잡 다양해져 잠재위험이 크다. 연구실의 사고예방 위해 무엇보다 중요한 것은 실험실 사고의 체계적인 분석이다. 대학이나 연구기관에서 연구실 사고사례의 체계적인 분석과 관리가 미흡하여 안전대책 수립이 어렵다. 본 연구에서는 화학물질 사용량과 폐기량 및 연구실 안전환경 인식도를 조사하였으며, 대학이나 연구기관의 연구실 사고 경향을 비교 분석하였다. 또한, 최근 화학물질로 인한 사고원인 분석과 사고로 부터 얻은 교훈 등을 살펴보고, 안전대책을 제시하여 연구활동종사자의 안전한 연구환경을 조성하는 방안을 논의해 보과 한다.

We face a common challenge of recession of shopping streets in both countries, Japan and Korea. In this article, we consider the issues and resolution policy on which centralized shopping street's revitalization for businesses and social community. After the establishment of “Three laws of community building”, Japanese shopping areas had any new problems against their business community and made the revitalization plan and carried out the policy. Though they could not strike home against their serious matters, in some shopping areas, inhabitant, school officials and public administration together to stem stagnation at the shopping community. Our topics will also include measures to combat depressed area, which is been increasing on Asian countries As a result, we can find three issue points. First, modernization and urbanization have progressed and many people does not enjoy contributing to a community. It is also a part of perception gaps between new migration and old community. Second, it's different in the problem that a shopping area holds depending on the scales of the market population. Third, a lot of shopping districts use, as traditional promotion, "soft promotion" which is concentrating on high service of cash, common advertisement, service tickets and common merchandise vouchers. We can find the activation policy which fit "economies of the scale" according to the nature of the shopping area.

본 연구는 작업장의 건축물이나 구조물의 구성요소로 사용되어지는 섬유강화플라스틱의 연소특성을 평가하였다. 섬유강화플라스틱의 연소특성은 ISO 5660에 따라 콘칼로리미터를 사용하여 수행하였다. 섬유 강화플라스틱의 착화시간과 열방출율은 복사열과 난연제의 함량에 따라 달랐다. 섬유강화플라스틱의 열방출율은 복사열의 증가에 따라 증가하였다. 섬유강화플라스틱의 착화시간과 최대 열방출율을 이용하여 플래쉬오버(Flashover)의 가능성을 Petrella가 제시한 분류방법에 따라 검토하였다. This study describes to assess combustion characteristics of fiber reinforced plastic (FRP) that is used an elements of building or structure in workplace. The combustion characteristics of the fiber reinforced plastic were carried out using by a Cone Calorimeter according to ISO 5660 standard. As the results of this study, the time to ignition and heat release rate of the fiber reinforced plastic was differ with heat flux of irradiance and content of flame retardant agent. The heat release rate of the fiber reinforced plastic was increased with increasing heat flux of irradiance. The flashover propensity of the fiber reinforced plastic using time to ignition and peak heat release rate was examined according to classification method by R.V. Petrella.
