In this study, take a look at natural disasters and technical characteristics such as frequency, bandwidth, transmission power, and service coverage of mobile communication and terrestrial broadcasting are compared as a means to provide disaster warning service in case of natural disaster, which is increasing in recent years. In the event of a disaster, mobile communication systems that take high frequency bands, low power transmission and narrow coverage can be disabled, but terrestrial broadcasting, which uses VHF and UHF with good frequency characteristics and high transmission power and wide service coverage provides stable services. As result terrestrial broadcast is useful as emergency warning or information in case of disaster.

Recently the study about a smart health care which is combined IT with BT to provide a variety of health care services are being actively investigated. In order to provide the best possible emergency medical services in a short period of time, it is necessary that the rapid emergency measures in the event of an emergency essential. In this paper, we propose an emergency medical service platform to take effective first aid to person who has a NFC tag or NFC-enabled mobile smart phones in an accident. Using NFC, it is possible to help without physical contact to the patient unconscious to emergency incidents such as falling down in everyday life. In this paper, we design and implement an mobile emergency medical system that can deliver first aid information ask for help in case of emergency.

Purpose: Despite the fact that the needs for disaster emergency medical facilities to minimize casualties are increasing, research for emergency medical facilities is insufficient compared to research for DMAT investment. A management strategy for emergency medical facilities in disaster site needs to be proposed. Methods: Recently there was introduction of mobile hospital system using unit modular method, but it was found out to be used only in disaster emergency training. Emergency medical facilities in disaster site require various tasks. Examination for our research was carried out through consultations with emergency medical and mobile hospital expert because there is no practical use case to apply Emergency Medical Facilities in Korea. Result: In this research we proposed a management strategy to manage and operate emergency medical facilities composed of tent, unit module and container in the aspects of management efficiency. Implications: It is highly expected to establish a foundation for fast and accurate disaster emergency medical facilities deployment by applying the results of our research to Emergency response manual of disaster emergency medical service.

Increasing the number of the solitude old person maintain a healthy lifestyle, the research for the emergency detection and life monitoring is required. In this paper, the wireless sensor network technology is utilized to design a silver-care service model in the area of emergency silver generation activities. The service model proposed in this paper acquired by using mobile devices to access silver-care service with the network information obtained through video monitoring and sensing. Also, Proposed model, based on wide-area network connected with the best wireless network of the PDA and mobile phones for the solitude old person.

Governments intend to use the public warning system to deliver timely and accurate information using accessible communication technologies for protecting the population and reducing damage to life and property. In particular, many countries implement system interworking with smartphones to notify of disasters or emergencies. In Korea, since 2020, due to the influence of the coronavirus disease, frequent emergency text messages led people to turn off related notifications, and complaints for receiving irrelevant messages from nearby warning areas have increased. Therefore, technical improvements for issuing more accurate disaster information to a specific region should be devised through a geography-based emergency disaster message transmission service. We analyze development trends of public warning systems and service cases of geography-based emergency text transmission services in various countries.

The emergency recovery scheme in time of a disaster or accident up to now has been focused on how to build a backup for the public service or communication network in national scale, also, all the mobile operators have done as recovery scheme for the equipment failure in their network was to make a backup copy of billing data or package data, and they have usually studied only on the backup and failure recovery scheme in the circuit-switched network. However, since it has become more probable recently that a disaster or accident could occur in the switching office buildings, a recovery scheme in time of the failure of these entire switching offices became necessary. The purpose of this paper is to propose various recovery schemes, and by having checkups on many issues that could arise while carrying out these schemes, it presents the best solution for each issue. Moreover, it presents the future tasks that need to be studied as well as initial study directions.

For suddenly encountered emergencies, most people embarrass, and can not often deliver the correct message when they report. Recently in the commonplace smart software environment, it is important that they can transmit the correct individual emergency situation efficiently and can receive the best service, and can provide the efficient emergency medical services to real-time around the other emergencies. In this paper, we design a standard protocol for the rapid and accurate technology for transmitting XML-based structured messages to provide an efficient emergency medical services, and offers a emergency medical services protocol to make them available more efficiently.

u-safety service system inter-works with the diverse operation agencies, through CCTV network, such as the emergency call terminal with built-in GPS, the mobile communication network, u-safety service provider, relay system and CCTV control center. In the case of the emergency call, this service searches the location of caller in real time, and then continues to search the location of caller through the control of CCTV in the searched place, and can provide the several agencies like guardian, police office, fire station, hospitals, relief organizations and municipalities, with the diverse information necessary for the secure rescue through SMS and wired network. In this paper, a new protocol and specification for u-safety service relay system is designed and implemented. The effectiveness of presented protocol is verified by computer simulation. The designed protocol of u-safety service is applied to real 3GPP and 3GPP2 mobile communication networks to verify its performance.

This paper proposes a novel resource allocation scheme which allows to guarantee the user-perceived service quality for various high-quality mobile multimedia service such as interactive game, tactile internet service, remote emergency medical service or remote disaster handling robot control to a certain level in the mobile networks. In our proposed scheme, Mean Opinion Score(MOS), which represents the degree of user satisfaction for perceived quality, is determined based on the delay limit allowable to each service. Moreover resources are allocated in consideration of this MOS. Simulation results show that our proposed scheme can decrease the outage probability in comparison with existing schemes Moreover it can increase the total throughput as well.
