In this paper, we propose an emergency call system which makes a call to an institution or a guardian when an urgent case occurs to a user based on the indoor location service. In addition, it establishes indoor location service infrastructure assuming welfare institutions and hospitals. The proposed system receives the sensor value from the device that is in the form of a clock on the wrist and determines the emergency situation and delivers emergency information to the terminal. The location terminal transmits location and emergency information to the server, and the server accesses the database and stores the data. This enables the caregiver to communicate with the server through the application, monitor the user's status, receive notifications, and respond to emergency situations by using the emergency call function. If the proposed system is applied to the fields requiring urgent action such as medical field and welfare field, it will provide more stable and prompt emergency service to users and carers.

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.

In this paper, we propose a system to monitor the condition of elderly people who are uncomfortable by using smart-phone and biometric sensor at any time and for care-givers to provide with the best medical service anytime and anywhere. The proposed system monitors the status of the elderly through various bionic sensors installed in the hospital ward based on the Arduino system and not only provides the physiological and medical services required by the elderly, but also informs the guardian so that he can cope with the emergency. In conclusion, this paper suggests that a reading light used by elderly people can operate as a home server with a biosensor using Arduino and Android applications (Apps.), and the smart-phone of care-givers is configured as a remote management and a emergency call system. Therefore, this study suggests important ways to improve the satisfaction of medical service for the both elderly people and care-givers of chronic diseases in the future.

본 논문에서는 클라이언트/서버 형태로 긴급 이벤트 자동 호출 기능을 처리할 수 있는 원격제어 시스템을 설계하고 구현하였다. 웹 애플릿을 기반으로 구현된 클라이언트 시스템은 상황실에 위치하여 직접적으로 제어를 담당하는 서버에게 원격제어 명령을 내린다. 제어 명령은 서버시스템으로 전달되며, 서버시스템에 존재하는 구동기가 실질적으로 컨베이어 시스템을 제어하는 기능을 가진다. 여기서 컨베이어 시스템은 승용차 조립라인을 시뮬레이션 한 것이다. 이러한 원격제어 시스템에 이동 통신의 문자서비스를 이용하여 긴급한 상황을 자동으로 원격지에 있는 관리자에게 알려주는 기능까지 확대시켰다. 관리자는 원격 시스템을 항상 감시할 필요가 없이 어느 장소에서나 상황보고를 받을 수 있다.

This paper presents a cal center which is a subsystem of a web-based real time monitoring system of intensive care units. Based on Computer-Telephony Integration (CTI) technology, the call center attempts to efficiently and automatically send messages to patients\` families, doctors, and other staffs in hospital via communication media suitable to the occasion. The problem of determining appropriate media can be very complicated by the urgency of a message, calling time, and communication media available to the target person. We use the Dempster-Shafer theory, one of the uncertainty handling methods, to determine the most suitable communication media that will transmit a message rapidly and safely. In addition, we use agent technology to perform the calling process without requiring the intervention of the user of the call center. this call center enables message transfer through various communication media in an integrated environment, and relieves medical staff from the calling process, which in turn will make a contribution toward enhancing medical service.

무선 단문전송 서비스(SMS : Short Message Service)란 이동 통신 세계화 시스템의 규격을 따른 무선 호출 서비스로 별도의 부가장비 없이도 40자 내외의 짧은 문장을 주고받을 수 있는 문자 서비스이다. 휴대전화의 보급이 급속도로 확산되면서 이에 비례해 문자 서비스 이용 인구도 급속히 늘어나고 있는데, 이메일과 달리 발송 시점과 거의 동시에 내용 전달이 가능하기 때문에 현재 통신수단의 하나로 이미 확고한 자리를 굳힌 상태다. 또한 근래에는 산업현장에서도 알람이나 FAULT정보 등의 신속한 전달을 위해 SMS에 대한 요구가 높아지고 있다. 이러한 시장의 동향에 따라 본 연구소에서는 산업 현장에서 알람이나 알림, 시스템 FAULT등 긴급한 사항에 대한 단문전송 프로그램을 개발하게 되었다.

In this paper, the u-Service system that is based on location-aware technology is designed and implemented for a silver town. On the real silver town the developed system has been employed and tested to provide convenient and secure living for residents. It provides services such as emergency call, intelligent elevator operation, and hands-free door access based on the location of the residents with personal device as called smart tag. It can also be applied to other service areas such as the location-aware u-Service for hospital, high-rising complex building, APT, etc.

The 4th industrial revolution is progressing by country as a mega trend that leads various technological convergence directions in the social and economic fields from the initial simple manufacturing innovation. The epidemic of infectious diseases such as COVID-19 is shifting digital-centered non-face-to-face business from economic operation, and the use of AI and big data technology for personalized services is essential to spread online. In this paper, we analyze cases focusing on the application of artificial intelligence technology, which is a key technology for the effective implementation of the digital new deal promoted by the government, as well as the major technological characteristics of the 4th industrial revolution and describe the use cases in the field of disaster response. As a disaster response use case, AI assistants suggest appropriate countermeasures according to the status of the reporter in an emergency call. To this end, AI assistants provide speech recognition data-based analysis and disaster classification of converted text for adaptive response.
