In mobile healthcare service, the accurate detection and the notification of the emergency situation are important to chronic patients' life. In the existing healthcare service, the medical staff or medical service provider always judges patients' health status by monitoring from the measured from bio-data. However, it is difficult to monitor many patients in real-time simultaneously, because the medical staff should monitor the health status continuously. Furthermore, an emergency condition diagnosis based solely on the statistical level of the bio-data may be difficult, since the emergency judgment of the bio-data might differ depending on the health characteristics of each person such as age, history of disease, gender, etc. In order to solve this problem, this article presents an mobile healthcare system for emergency bio-data management using a personalized emergency policy. The salient feature of the proposed mobile healthcare system is that the characteristics of the health status of an unique patient is defined to the policy, which is used to judge the emergency condition of the bio-data measured from the patient. The prototype of proposed mobile healthcare system has been built to demonstrate the design concept.

This study aims to provide information about the acute poisoning patients transferred by 119 ambulance service for nurses and emergency medical technicians. The data is based on 119 ambulance services patients charts of Seocho area in Seoul. The results were as follows: 1. Total number of emergency patients all over the country has been nearly fourtimes in 1995 compared to 1991. Total number of emergency patients were 322.051 in 1994. 2. About $35\%$ of total E.R. patients were transferred by 119 ambulance services in Seoul in the last 5years. Acute drug intoxication patients occupied $2-3\%$ of E.R. patients in Seoul. 3. About $4\%$ of E.R. patients in Seoul were transferred by 119 E.R. services of Seocho area in Seoul in 1995. Among them $2.4\%$ patients were drug intoxication patients. 4. Data were collected from available patients of 119 ambulance services from Jan. 1993 to Dec. 1995 in Seocho area. Total poisoning patients were 184. - The female/male ratio was 69.7:30.4 and most of patients$(69.7\%)$ were in the age of 20th and 30th. - The busy time of calling 119 ambulance service was from 6P.M. to midnight$(37.5\%)$ - It took within 10 minutes for patients$(62.8\%)$ from notification to arrival in hospital. - Regarding poisoning substances. hypnotics $(22.8\%)$, tranquilizer$(14.7\%)$, agricultural agents$(6.0\%)$ rodenticide$(27\%)$ and others $(10.3\%)$ were in order and unknown were $43.5\%$. - Most of the patients or protector $(72.8\%)$ chose hospitals. Among them $(87.3\%)$ were general hospital. - The most predominant symptoms were coma$(22.3\%)$. dizziness$(6.5\%)$ and then allergy. vomiting. gastrointestinal cramps etc. - Airway management and oxygen administration together was the main medical control of prehospital emergency medical services$(33.7\%)$. It is proposed that first, a systematic survey of drug intoxication patients must be conducted to give an appropriate prehospital emergency care for the emergency medical technician and second, a wide and regular public education to improve understanding of first aids should be undertaken.

The number of motor vehicle registrations in Korea is increasing steadily each year, driven by industry development and economic growth. The number of traffic accidents is also rapidly increasing. Korea has a relatively high number of traffic accidents among OECD member countries, and it ranks among the highest in traffic accident death rates. This death rate is higher compared to death rates as a proportion of the number of traffic accidents in each country. It is very common for drivers to lose consciousness in traffic collisions, which leads to a failure to carry out early emergency measures. In order to prevent such situations as well as hit-and-runs and people left uncared for after traffic accidents, there is a need for motor vehicle black boxes and accident report systems. This study addressed the need for an emergency evacuation system for people injured in traffic accidents and a secondary traffic accident prevention system by developing a motor vehicle emergency situation detection and report system combined with a black box, and materializing it as an actual system.

Cognitive radio (CR) MAC protocol provides access control of unused spectrum resources without causing interference to primary users. To achieve this goal, in this paper a TDMA based cooperative multi-channel cognitive radio MAC (MCR-MAC) protocol is proposed for wireless ad hoc networks to provide reliable protection for primary users by achieving cooperative detection of incumbent system signals around the communication pair. Each CR node maintains transmission opportunity schedules and a list of available channels that is employed in the neighbor discovery period. To avoid possible signal collision between incumbent systems and cognitive radio ad hoc users, we propose a simple but efficient emergency notification message exchanging mechanism between neighbor CR nodes with little overhead. Our simulation results show that the proposed MCR-MAC can greatly reduce interference with primary users and remarkably improve the network throughput.

In this paper, we tried to find the engineering feasibility of the component functions of the seven selected application technologies which are going to be installed on the next generation high speed train as the IT and smart sensor application technologies. The component functions of the seven applications, including the "Emergency or reminder notification", were identified and analyzed. In order to justify the feasibility of applications development, effect analysis and sufficiency analysis were performed. In effect analysis, how each function has an effect on safety, convenience, and efficiency of the passengers and attendants was evaluated. In sufficiency analysis, the importance and implementability of each function as a component was evaluated. The feasibility analysis was focused on the technical aspects of the functions. The following work will be the settlement of the final applications that are going to be designed and implemented. This will be done by studying the strategic feasibility in relation to the service or business of the high speed train.
