This paper presents the system interface standard that are associated with additional devices like sensor nodes as well as fire monitoring panel, panic button and emergency call in city railroad environment. Existing fire monitoring panel, panic button and emergency call system is responsible for fire detection and alarm, emergency alarm and communication with the manager. Recently, researches that are associated with NVR-based intelligent integrated surveillance systems and existing alarm system are activated but most of the system is dedicated to it existing. In order to expand devices that is supported other monitoring function, separate device configuration or modification of integrated surveillance system are inevitable. In this study, interface standard between standard controller, integrated command center and each device that facilitate additional expansion of integrated surveillance system and avoid the extra cost is presented.

Purpose: To evaluate the emergency medical protocols and need assessment through the case report Method: The study investigated the emergency call system through the 1339 emergency patients information center in 1997. Results: The emergency calls tend to follow general trends of the type of cases : abdominal pain (13.5%), unconsciousness(12.0%), traffic accidents (7.4%), bleeding (6.6%), respiration difficulty (5.9%). This was all collected through emergency medical protocols injury and poisoning (22.3%), symptom (51.6%), others (26.1%). Conclusion: The results suggest that a specific training program for emergency medical dispatchers should be established, and emergency medical dispatcher managers must review the cases on the basis of emergency medical protocols every year. Emergency medical services, furthermore, will continue to raise the standard for emergency medical dispatching.

As the development of the various IP-based services, it is expected that Internet telephony service will gradually replace the traditional PSTN-based telephony service. But there are many issues resolved to spread the Internet telephony service. One of them is to support the emergency services in the Internet telephony. In the case of USA, it has been regulated that 911 services should be supported in the Internet telephony services using VoIP on the similar performance level to PSTN 911 service. According to the regulation, basic VoIP 911 calls should be routed to the general access line of LEA without the location information or the callback number, but the enhanced VoIP 911 calls with the location information and callback number should be routed on the dedicated 911 network and destined to the local 911 distribution center such as PSAP. But, in the current VoIP-based Internet telephony network, the emergency call service has not been handled as one of the special services as well at has a worse performance in comparison to it on PSTN. Moreover, the service has a critical problem that it can not be destined to the nearest PSAP because of the insufficient information about the location information and the call back number. In this paper, we suggest the SIP-based emergency call service mechanism in order to resolve the problems above mentioned. This suggested mechanism is implemented to show its effectiveness and efficiency.

Low-Orbit satellite mobile networks can provide services through miniaturized terminals with low transmission power, which can be used as reliable means of communication in the national public disaster network and defense sector. However, the high traffic environment in the emergency preparedness situation increases the new call blocking probability and the handover failure probability of the satellite network, and the increase of the handover failure probability affects the QoS because low orbit satellites move in orbit at a very high speed. Among the channel allocation methods of satellite communication, the FCA shows relatively better performance in a high traffic environment than DCA and is suitable for emergency preparedness situations, but in order to optimize QoS when traffic increases, the new call blocking and the handover failure must be minimized. In this paper, we propose LEO-DBC (LEO satellite dynamic beam width control) technique, which improves QoS by adaptive adjustment of beam width of low-orbit satellites and call time of terminals by improving FCA-QH method. Through the LEO-DBC technique, it is expected that the QoS of the mobile satellite communication network can be optimally maintained in high traffic environments in emergency preparedness situations.

Purpose: The aim of this study was to compare the toxicologic profiles and outcome of poisoned patients by comparing the data obtained through telephone counselling, each provided by emergency medical information center (1339) and emergency dispatch center (119). Methods: We analyzed the telephone-based poison exposure data before and after Seoul 1339 merged to 119. We compared the Seoul 1339 call response data in 2008 with Seoul and Busan 119 call response data between 2014 and 2016. We analyzed the changes in the trend and quality of data obtained, as well as the quality of service provided by each center before and after this reallocation, by comparing the data each obtained through telephone counselling. Results: The data was collected for a total of 2260 toxin exposure related calls made to Seoul 1339 in 2009, and 1657 calls to 119 in Seoul and Busan between 2014 and 2016. Significant difference was observed for age, sex, and reason for exposure to toxic substance between the two groups. Conclusion: After the integration of 1339 with 119, 119 focused on role of field dispatch and hospital transfer, lacking the consulting on drug poisoning. Moreover, data on exposure to toxic substances at the pre-hospital stage indicate that drug information and counseling are missing or unknown. In addition, first aid or follow-up instructions are not provided. Thus, systematic approach and management are required.

When an applicant requests the emergency situation call or safe return service using a smart device, the smart surveillance service can select the CCTV(closed circuit television) cameras around the applicant using applicant's location information, then automatically takes a photograph to track the applicant. Since the surrounding CCTV camera shoots the applicant continuously using location information and the applicant can be observed by the monitor agent in real time, this service can be very helpful in an applicant's emergency situation or safe return. The existing smart surveillance service does not consider the priority of the emergency situation call and safe return service. Therefore, there is the disadvantage that the applicant who requests an emergency situation call service can not be photographed when safe return service has already preoccupied CCTV cameras which are capable of taking a picture of the applicant. The proposed smart surveillance service improves this disadvantage by using service priority.

Purpose: We aimed to compare the transport time, the proportion of direct hospital visit and the emergency procedures between the current mountain rescue helicopter emergency medical service (HEMS) and physician-staffed mountain-rescue HEMS. Methods: During weekends from October 2, to November 21, 2010, 9 emergency physicians participated as HEMS staff in the mountain-rescue HEMS program of the Seoul fire department. Patient demographic data, transport time, proportion of direct hospital visits, and emergency procedures were recorded. We also collected data on HEMS mountain-rescued patients from June 1, to September 1, 2010, and we compared them to those for the study patients. After an eight-week trial of the HEMS, we performed a delphi survey to determine the attitude of the physician staff, as well as the feasibility of using a physician staff. Results: Twenty-four(24) patients were rescued from mountains by physician-staffed HEMS during the study period, and 35 patients were rescued during the pre-study period. Patient demographic findings were not statistically different between the two groups, but the transport time and the emergency procedures were. During the study period, the time from call to take-off was $6.1{\pm}4.1min$ (vs. $12.1{\pm}8.9min$ during the pre-study period, p-value=0.001), and the time from call to arrival at the scene was $15.0{\pm}4.8min$ (vs. $22.3{\pm}8.1min$ during the pre-study period, p-value=0.0001). The proportions of direct hospital visit were not different between the two groups, but more aggressive emergency procedures were implemented in the study group. The delphi survey showed positive agreement on indications for HEMS, rapidity of transport and overall satisfaction. Conclusion: A pilot trial of physician-staffed HEMS for mountain rescue showed rapid response and more aggressive performance of emergency procedures with high satisfaction among the attending physicians.

Due to almost all tracks of new Kyoungbu high-speed lines(HSL) consisting of bridges and tunnels, HSR operational safety management is very important factor for passenger safety and preventing catastrophic event. Especially, it is important to approach the scene of the accident and assist in saving lives as soon as possible under emergency conditions. Therefore it is essential to prepare access methods and available resources in advance in order to support emergency correspodances promptly and effectively. This paper persents an application of geographical information system(GIS) for developing emergency management system as well as batabase system on tracks and facilities, electric/communication equipment and safety equipment required to support emergencies. The on-site information on the proximity of HSL is expressed on the numerical map, which can be helpful to call external supports such as medical service, local authorities, police offices, fire brigades, and etc. for the emergency situations.
