Notifying emergency evacuation methods, accurate disaster location and evacuation route guidance can be very active alternatives to quickly minimize evacuation and casualties in disaster situation in the development of subway disaster prevention detection system that detects the disaster signs at the subway station early on the basis of Internet of things and leads passengers to evacuate. It's not easy to ensure perfect functioning of fire fighting facilities and equipments due to underground space structure with narrow exits. Therefore, we developed disaster provision EL Display integrated board that can induce the most efficient evacuation and the field experiment was conducted to examine the practical application in this study. Especially the applicability was verified by field application test because there is no case in which EL panels are used to evacuate disasters.

Life and Property damage has increased during traffic congestion and isolation because natural disasters such as flood and landslide have occurred every year. When disaster occurs, if there is insufficient information in advance when entering the flooding areas which subsequently cause confusion. In this paper, we developed the system that could provide display of detour route using disaster information and evacuation route in disaster areas. User will receive result of analysis using smart phone application to prevent additional damages when disaster areas were entered by manager.

Currently, most small theaters in Korea are not equipped with fire escape prevention laws unlike large theaters. The small theater is a place where many people stay in a small space, which can lead to a great deal of damage in the event of a fire. Therefore, we propose an efficient evacuation method using the evacuation behavior of the crowd as a way to minimize the casualties in case of a fire in a small theater.

실내 공간 용용기술의 핵심은 3차원 실내공간데이터의 모델링 기법과 이와 연동 가능한 센서기술이다. 하지만 아직은 실내위치기반서비스를 위한 측위기술 및 공간데이터에 대한 표준과 활용방안이 제한된 상태이다. 본 연구에서는 실내 위치기반서비스에서 사용 가능한 간단한 공간 DBMS 기반의 3차원 실내 공간 데이터 모델의 구축방법과 이를 활용할 수 있는 방법론을 제시하고자 한다. 본 연구에서 제시하는 모델은 2차원 기반의 multi-layer 구조를 가지며, 2차원 및 3차원으로 가시화가 가능하도록 하였다. 또한 제시한 3차원 실내 공간 모델의 실내 기반 서비스로의 적용을 테스트하기 위하여 CA(Cellular Automata)기반의 대피 시뮬레이터와 대피 경로 안내 시스템 그리고 실내센서(카메라)와의 연동 등 몇 가지 응용분야에 대한 테스트를 수행하였다.

The existing wireless village broadcasting systems use the method to connect to village broadcasting system using wire/wireless telephone to announce the important notices, public relations, and disater status. This type of systems have the problems that if broadcaster is facing rough going or forget the announcement time, it is impossible to inform village people important contents, urgent disaster status, evacuation method. This paper describes internet based village broadcasting system using mobile App to solve these problems. Broadcaster can save the voice and send the voice to App server using the mobile App to activate that voice specific day and time. This mobile App system can improve the efficiency and customer satisfaction of village broadcasting system.

With the rapid development of modern society, subway has become one of the most typical urban transport systems. Since fire accident occurred at Daegu subway in 2003, importance of life safety and disaster prevention have been widely recognized and many studies have been carried out. As a result of these studies, fire-retardant and non-combustible interior material and platform screen door with passenger guide indication device have been developed, but studies on a subway evacuation criteria have been in a stalemate. Therefore, this study is intended to improve the subway evacuation standard. It is very difficult to take into account whole subway system, so a typological approach to a ticket was carried out referring to previous studies focused on a subway platform. this paper selected the most common subway platforms and estimated evacuation time among 10 platforms from previous studies and 8 from this study. As a result, evacuation time exceeded 6 minutes which is the guideline of existing standard. Therefore, it is necessary to update the standard for evacuation time and add supplementary conditions which can help establishing the measures for safety facilities and prevention measures.

The building infrastructures such as high-rise buildings, shopping malls, exhibition centers, etc. are becoming larger in magnitude and more complex in complexity. Considering a large number of tenants and visitors are staying in these facilities, it is upper most important to keep those in safe from fire outbreak. In this paper, a u-Disaster Prevention System has been presented to provide effective fire evacuation when fire breaks out in building infrastructures. The ubiquitous sensor network (USN) technology was applied to detect heat and smoke from fire outbreak. The information then is transmitted wirelessly to a host computer. The tenants and visitors residing in the facility can evacuate following the instruction that is displayed in LED sign boards of the u-Disaster Prevention System. A case study shows that the ubiquitous environment can help people evacuate faster in time, shorter in distance with the assistance of the u-Disaster Prevention System.

Previous studies related to evacuation guidance systems are focused on the system construction, and research on manual of the standard evacuation map is insufficient. Therefore, this research is a basic study to establish the standard evacuation map, and analyzed the decision-making time according to the type and size for each component of the evacuation map. Experimental elements were derived through the review of previous studies and legal regulations. After that, decision-making time was analyzed according to the type and size of the component display method. An experiment was conducted to analyze the decision-making time according to the type and size of the component display method. Afterwards, through the statistical test, the evacuation map guidelines for smartphones were proposed.

This paper describes the development of a network-based passenger information system(PIS) which provides the convenience of the passenger of the train and heightens the effect of the subtitle service, the advertising and the shelter guidance broadcasting against the urgent event. The existing system uses VGA signal distributor in order to broadcast information with image and subtitle and voice guidance. In this paper we improve the existing system by applying the UDP and TCP/IP protocol and use a reference clock to solve a data loss and synchronization problem which occurs in this case. We also developed an XML-based subtitle authoring tool which can edit and play the subtitles with various 3D to improve the automatic guidance broadcasting and advertisement effect according to the operation schedule of the train. The system performance was evaluated through a simulation.
