최근 자연적•사회적 요인으로 인해 재난의 규모와 복잡성이 점점 증가하는 양상이며, 이로 인해 단일 기관의 대응 만으로는 한계가 있다. 다수 기관이 동일한 현장에서 재난대응을 할 경우 유기적인 상호 협력을 위해서는 사전에 합동대응 을 위한 대비가 필요하다. 재난대응계획은 재난발생 시 대응기관 간 역할과 책임을 규정한 것으로서, 특히 합동대응을 원활히 하기 위해서는 기관 간에 수평적•수직적 상호협력체계가 명시되어 있어야 한다. 본 연구에서는 현재 수립하고 있는 안전 관리계획, 위기대응매뉴얼 등 다양한 계획과 매뉴얼들의 현황을 살펴보고 문제점을 도출하였으며, 외국 사례의 분석을 통해 실효성 있고, 수직적•수평적 협력이 가능한 재난대응계획의 구조와 내용 등 발전방안을 제시하였다. Recently, scale and complexity of disaster are increasing by natural•social factor, and there is limit for emergency response by single agency thereby. Therefore, when multi-agency conduct a response for disaster together at the scene, they need preparation for joint response in the advance for systematic mutual cooperation. Preparedness consist of various factors such as planning, securing of Organizations and resource, continuous education and training. This paper focus on emergency response plan and examine the existing state and problem of various plans and manuals. Also submit development way for establishing emergency response plan that had effectiveness through the foreign case analysis.

최근 집중호우로 인한 산사태, 구미 불산 누출사고 등 국민의 인명과 재산에 막대한 손실을 입히는 중대재난이 계속 발생하고 있지만, 이에 대한 대처가 불충분하여 재난으로부터 안전한 사회에 대한 국민의 요구가 한층 증대되고 있다. 본 논문은 재난관리 전문가 양성을 통한 방재교육역량 강화를 위해 방재부문의 교육 컨텐츠 체계 정립의 핵심기반을 마련 함을 목적으로 한다. 이를 위해 우선 수요예측에 의한 교육과정 및 교육과목을 설계하였으며 이를 기초로 하여 재난 현장대비 및 대응 중심의 교육과목을 설계하였다. Recently, inflicted damage for people's life and property from occurred major disaster that landslide by localized downpour and hydrofluoric acid leak from the Gumi. However public needs about safe society is more increasing from disaster because response is unsatisfactory on that. The purpose of this paper is that establish the core foundation for the education contents system of disaster management through cultivating expert. Therefore first, designed the training of course and subject by demand forecast. Next, designed the training course focus on preparedness and response at on-scene.
Cooled EGR이 직접분사 DME엔진의 배기특성에 미치는 영향

There are high expectations for DME(Dimethyl Ether) as a new alternative fuel for diesel engine. Compared with the conventional diesel engine, nearly zero soot emission and high thermal efficiency have been reported from DME fuelled Cl engines. However, higher NOx emission is one of the disadvantages from DME Engines. In the present study, cooled EGR(Exhaust Gas Recirculation) was applied to DME engine modified from conventional Dl diesel engine, and effects of EGR were examined under various EGR rate and EGR temperature. Finally, it was concluded that the cooled EGR is an effective solution to reduce NOx emission from DME engine.<br/>

The application of Diesel Particulate Filter (DPF) as after-treatment system has been studied to reduce particle mater(PM) in exhaust gas form vehicle, but there is one challenge which is a regeneration method in the low temperature region. In this study, DPF was heated with heating device that is consisted of two combustion catalyst. Diesel fuel(2'nd fuel) was oxidized on 2'nd combustion catalyst layer which was heated by thermal energy supplied from diesel fuel(1'st fuel) combustion on 1'st catalyst layer. DPF was mainly heating to more than 650℃ with 2'nd fuel and oxygen in exhaust was used as oxidant. An efficiency of 2'nd fuel combustion on 2'nd catalyst layer is dependent on flow rate and oxygen concentration. Thus 2'nd fuel was oxidized when oxygen concentration in an exhaust gas stream is high, but that was oxidized on DOC when oxygen concentration is low. Nevertheless temperature of front of DPF was maintained as 650±50℃ apart from a driving condition of vehicle.

The application of Diesel Particulate Filter (DPF) as after-treatment system has been studied to reduce particle mater(PM) in exhaust gas form vehicle, but there is one challenge which is a regeneration method in the low temperature region. In this study, reforming reaction of diesel fuel was applied as regeneration method. Reforming reaction of diesel fuel to reformate (H₂ and CO) was conducted on PUCe/Al₂O₃ that was made through impregnation method. Reformate was mixed with exhaust gas and gas mixture was injected to DOC. Possibility to apply reforming system was evaluated with the temperature of the exhaust gas on the rear of DOC. In condition that the temperature of exhaust gas was 150℃, the temperature of exhaust gas on the rear of DOC was easily heated to more than 450℃ by reformate of diesel fuel.
