Health and disease related characteristics of 226 selected by systematic sampling from 452 personal emergency response system(PERS) beneficiaries and actual conditions of using PERS by them are as follows. Over 86% of PERS beneficiaries have not good health conditions and 70.7% of them have chronic diseases. On social supports family was highest as 52.2% and cases having social workers' assistance were 15.2%, but 53 as 23.7% had not visit or call from anyone and showed very low social supports. 86.2% was given PERS within 3years and 79.1% had it by the recommendation from related agencies and 4.0% was by their demand. On wearing it, 78.3% didn't bring it with them and 92% of them answered they were not sick and then it was found that they didn't use it because they had not special emergency. On satisfaction with paging system's operation, 81.3% answered they were satisfied with it, 48.8% used it for 'acute and emergency diseases' and 29.3% called ambulance for 'appointed medical treatment'. Time required for ambulance to arrive at the field was within 10 min. in 87.8% and after 10 min. in 12.2% and emergency service for beneficiaries by fire service was very good. On satisfaction with use of PERS, 85.4% were satisfied with it, 81.9% who requested repair or replacement of radio paging got it back after one or two days of their request and they answered they were satisfied with A/S. 45.5% answered they powered off it because 'they didn't use it' and 12.1% had 'economical reason of phone charge'.

The u-Healthcare system, a new paradigm, provides healthcare and medical service anytime, anywhere in daily life using wired and wireless networks. It only doesn't reach u-Hospital at home, to manage efficient personal health in fitness space, it is essential to feedback process through measuring and analyzing a personal vital signs. MBAN(Medical Body Area Network) is a core of this technology. MBAN, a new paradigm of the u-Healthcare system, can provide healthcare and medical service anytime, anywhere on real time in daily life using u-sensor networks. In this paper, an ontology-based context-awareness in MBAN proposed system development methodology. Accordingly, ontology-based context awareness system on MBAN to Elderly/severe patients/aged/, with measured respiratory rate/temperature/pulse and vital signs having small variables through u-sensor network in real-time, discovered abnormal signs and emergency situations which may happen to people at sleep or activity, alarmed and connected with members of a family or medical emergency alarm(Emergency Call) and 119 system to avoid sudden accidents for early detection. Therefore, We have proposed that accuracy of biological signal sensing and the confidence of ontology should be inspected.

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.

An emergency service over Voice over IP (VoIP) network is an essential condition, like the existing telecommunication services. To support for the emergency services, standardization works have been performed. The National Emergency Number Association (NENA) has been developing the framework and procedures for an emergency service for Non-IP based network, rather than protocols. In contrast, the Internet Engineering Task Force (IETF) has been only focused on end-to-end IP-based emergency calls. The NENA architecture is incompatible with the IETF protocols. To solve the problem, we design and implement a SIP-based VoIP emergency system by adopting the NENA architecture and by applying IETF protocols, for both IP-based Pubic Safety Answering Point (PSAP) and PSTN-based PSAP. It is implemented and tested under UNIX environment.

Currently, there are a total of 68 emergency rooms based on Seoul, South Korea, and there is a portal site that allows you to inquire the location of the emergency room, but it is difficult to use in an actual emergency situation because it consists of selecting a gu and a self-governing dong. In addition, it may be more efficient to go to the emergency room directly because you may miss the golden time necessary for survival in a situation where you call 119 and wait for the rescue team. Therefore, in this paper, we propose a service that can quickly search the location of the emergency room based on a specific location through various functions supported by MongoDB. After downloading emergency room location data based on Seoul Metropolitan City, storing it in MongoDB, processing the data through various processing techniques, and applying a spatial index, you can query the emergency room based on distance from a specific location in real time.

IP and SIP public broadcasting systems developed in Korea and abroad are developed in a Windows or Linux server environments and are installed in a server-rack structure, have high power consumption, and are difficult to remotely respond to system failures. In this paper, IoT platform is designed to connect IoT device and gateway to IoT service server by using internet service structure. We also designed a server based on embedded OS that can provide a variety of public safety management services according to the order of the server with built-in call processing and broadcasting function that can handle emergency calls and emergency broadcasts in public places using this structure. This server is interoperable with a variety of SIP-based call and broadcast devices that support the standard SIP and can be integrated with an in-house phone and on-premises system.

Recently, much attention to a self-organizing mobile ad-hoc network is escalating along with progressive deployment of wireless networks in our everyday life. Being readily deployable, the MANET (mobile ad hoc network) can find its applications to emergency medical service, customized calling service, group-based communications, and military purposes. In this paper we investigate a time slot exchange problem found in the time slot based MAC, that is designed for IEEE 802.11b interfaces composing a MANET. The paper provides a method to maintain the quality of voice call by providing a new time slot when the channel assigned for that time slot gets noisy with interferences induced from other nodes, which belong to the same and/or other subgroups. In order to assess the performance of the proposed algorithm, a set of simulations using the OPNET modeler has been performed assuming that the IEEE 802.11b interfaces are operating under a modified MAC, which is a time slot based reservation MAC implemented in the PCF part of the superframe. In a real-time voice call service over a MANET of a size 500 ${\times}$ 500 meter squares with the number of nodes up to 100, the simulation results are collected and analyzed with respect to the packet loss rate and packet delay. The results show us that the proposed time slot exchange protocol improves the quality of voice call over that of plain DCF.

During the past 5 years, domestic VoIP service has grown rapidly absorbing more than 8 million subscribers. More recently, the increase of enterprise or institutional subscribers become more dominant than individual subscribers. Supporting emergency services such as 119 in these scaled up VoIP services is very essential. In current domestic VoIP networks, the VoIP terminal's location information which are provided to the PSAP with the arriving emergency call depends on the information which are entered at the subscription time or updated by the subscribers when the terminal is moved to other place. This manual provision of location information which requires the user's intervention can result in serious failure in saving people in emergency situations, in case that users are negligent in entering the information or users enter the wrong information. In this paper, we propose an enhanced mechanism in which the terminal's location information is automatically offered by the network for emergency services in ethernet-based enterprise VoIP networks.

The Purpose of this study is to search for ways to improve the police-related emergency reporting service through the analysis of its actual condition - focusing 112 emergency reporting & 122 emergency reporting. For this purpose, the main data related to police-related emergency reporting required for inspection of the administration conducted by the National Assembly in 2013 is utilized. The actual condition of the police-related emergency reporting service is examined in 3 aspects - the number of reported cases by reporting type, the number of police response, and the average arrival time. The principal analysis results of the actual condition revealed that 112 emergency reporting is increasing and 122 emergency reporting oscillates between increases and decreases in the total number of reported cases, the number of non-emergency reporting is increasing in both 112 and 122 reported cases, the number of prank call is high in 122 reported cases, the rate of other agency transmit($122{\rightarrow}112$) is higher than 12% in 122 reported cases, and the number of police response and the average arrival time are decreasing in 112 reported cases. To improve the police-related emergency reporting, based on the above actual condition, the followings are required: to operate dualistic police-related response; to publicize a police-related reporting service; to take stern measures against false report; to make continuous improvement of the police-related emergency reporting system.
