독거 환자의 특성상 간병인이 없는 관계로 응급 구난시 모든 일을 스스로 해결해야하는 문제점이었다. 이때 독거 환자들을 응급 구난 할 수 있는 시스템 개발이 사회적으로 필수적인데 이러한 독거환자 응급 구난 시스템은 혼자 생활하는 독서환자들이 저비용으로 쉽게 구입할 수 있고 리모콘으로 설계되어 휴대가 간편하고, 그리고 사용하기 쉽다. 또한 이리한 시스템은 간병인이 없는 독거 환자에게 사회복지 차원에서 널리 사용될 것으로 기대된다.

Marine casualties of dangerous cargo carriers lead to not only the loss of human life and properties, but also marine pollution caused by spilled oil and hazardous cargo. So the prevention of marine casualties and emergence response to minimize pollution are very important problems to be settled. But until now, most of salvage assistance jobs have been done based on rule of thumb without any technical support. It is not easy to cope with the incidents safely and rapidly under the current situation. The purpose of this paper is to develop a systematic and engineering salvage assistance tool available in the casualty sites. This paper contains the construction of salvage system, classification of technical items, and prototype system for the safety assessment. The developed system enable a salvage engineer in his/her salvaging jobs to perform safely and promptly.

There has been increasing the possibility of occurring the marine accident and become bigger the extent of damage with the growing number and high speed of ships. Also, there were tremendous loss of lives and properties in accidents of Hebei spirit in 2007 and Cheon Ahan war ship in 2010 with the insufficient salvage response and the lack of emergency response systems. When a ship has suffered an incident, the best way of preventing damage or pollution from its progressive deterioration would be to providing a place of refuge and to repair the damage rapidly. Therefore, it was examined the recent collision accident broken out near the Nam-Hae, and then suggested that it was necessary to be improved of the domestic salvage systems. It requires the procedures of providing a place of refuge, and the towing support system which make the damaged ship moved to the safe area, and joining of the ISU.

Visibility is very poor in tunnel fire because of confined space where the fire may easily lead to the mass casuality incident because of fast smoke spread. In this test, air curtain and the fan were installed at rescue station in a bid to make use of rescue station in safe way during the train fire in undersea tunnel and a full-scale fire test was conducted to identify the applicability of air curtain system. Air curtain system was installed at a real rescue station and the test was continued for 2 minutes till heptane which was used as fire source was completely burned out. When air curtain was working, difference in temperature between inside and outside the platform was $160^{\circ}C$ and carbon monoxide measured inside the platform was less than the case of no air curtain system by 160 ppm. Thus a full-scale fire test demonstrated that the air curtain system installed at rescue station in undersea tunnel was able to effectively block the heat and smoke generated from the fire.

As ICT technology develops, researches on the construction of communication system for the rapid processing using ICT technology in case of traffic accidents are actively under way. e-Call (Emergency call) is a vehicle ICT-based emergency rescue system that recognizes and reports traffic accidents. On the other hand, the existing bus information system collects the positioning data through the position tracking system mounted on the bus and transmits it to the center, and then provides various services based on the bus information of the collected buses. In this paper, we designed and implemented an emergency rescue system that using the existing bus information system in order to deal with accidents, failures, and emergency situations on public buses quickly.

In this study, the l/35 reduced-scale model experiment were conducted to investigate designed ventilation system performance at rescue station in tunnel fire. A model tunnel with 2 mm thick of steel, 10 m long, 0.19 m high and 0.26m was made by using Froude number scaling law. The cross-passages installing escape door at the center. were connected between accident tunnel and rescue tunnel. The n-heptane pool fire, $4cm\times4cm$, with heat release rate 698.97W were used as fire source. The fire source was located in the center and portal of accident tunnel as Worst case.. An operating ventilation system extracted smoke amount of 0.015 cms. The smoke temperature and carbon monoxide. concentration in cross-passage were measured to verify designed ventilation system. The results showed that, in center fire case without ventilation in accident tunnel, smoke did not propagated to rescue station. In portal tire case, smoke spreaded to rescue station without ventilation. But smoke did not propagated to rescue station with designed ventilation.

Recently the U-Healthcare system has been rapidly advanced to manage emergence rescue for seniors. We can access emergency rescue systems with high quality services anytime, anywhere under ubiquitous healthcare systems. The more the various systems develop, the more software security systems become important. Therefore, the safety-critical system has been widely spread to the world by advancement of the information and communication technologies. There are a lot kind of fault analysis methods to evaluate software security systems. However due to characteristics of software that is not applied by human error, it can be prevented the enormous damages and losses from improving the safety of safety-critical system. So this paper proposes an integration method of FTA and Forward and Backward FMECA. This method has each strength of FTA and FMECA which is visual and numeric in normalization. First, by use of FTA, we can redraw FTA with Forward FMECA and Backward FMECA in consideration of occurrence, severity, detection, correctness, robustness, and security. Also according to value of NRVP at each event, we can modify FTA diagrams as shown critical paths given by severity and occurrence. Also, we propose the improved emergency rescue service platform of ubiquitous healthcare systems through identifying priorities of the criticality according to normalized risk priority values (NRPV).

우리나라에서 119 구급대를 운영하는 것과 같이 각국은 실정에 따라 여러가지 구급기관을 운영하고 있다. 그중에서도 일부 선진국들은 항공기를 이용한 긴급 구난 구호 시스템을 두고 보다 효과적으로 인명 구조에 나서고 있다. 그중에서 특히 타국의 모범이 되고 또 특이한 조직과 활동으로 눈부신 활약을 보이고 있는 예를 우선 3개국만 거론해 보기로 한다.

This study introduce that we studied optimization and possibility of smoke spread prevention with air-curtain system in undersea tunnel named from Ho-Nam to Jeju line in domestic if a fire break out in train. To verify performance, air-curtain system is installed between rescue station platform and each door of passenger car to provide safety route to evacuator and we studied simulation model of various cases about 15 MW fire severity considering domestic specifications. As a result we verified the fact that CASE1(air jet with 15degree toward passenger car) and CASE 5 (air jet with 15degree toward passenger car and pressure air blast from cross passage) is best Smoke Spread Prevention and less inflow carbon monoxide. Through above results, we expect that air-curtain system is one of the facilities for fire safety and provide us safety platform route in undersea tunnel.
