In the current medical information system, a system environment is constructed in which Biometric data generated by using IoT or medical equipment connected to a patient can be stored in a medical information server and monitored at the same time. Also, the patient's biometric data, medical information, and personal information after simple authentication using only the ID / PW via the mobile terminal of the medical staff are easily accessible. However, the method of accessing these medical information needs to be improved in the dimension of protecting patient's personal information, and provides a quick authentication system for first aid. In this paper, we implemented an automatic authentication system based on the patient's situation and evaluated its performance. Patient's situation was graded into normal and emergency situation, and the situation of the patient was determined in real time using incoming patient biometric data from the ward. If the patient's situation is an emergency, an emergency message including an emergency code is send to the mobile terminal of the medical staff, and they attempted automatic authentication to access the upper medical information of the patient. Automatic authentication is a combination of user authentication(ID/PW, emergency code) and mobile terminal authentication(medical staff's role, working hours, work location). After user authentication, mobile terminal authentication is proceeded automatically without additional intervention by medical staff. After completing all authentications, medical staffs get authorization according to the role of medical staffs and patient's situations, and can access to the patient's graded medical information and personal information through the mobile terminal. We protected the patient's medical information through limited medical information access by the medical staff according to the patient's situation, and provided an automatic authentication without additional intervention in an emergency situation. We performed performance evaluation to verify the performance of the implemented automatic authentication system.

As Republic of Korea community nears to old age society rapidly, various kinds problem about old mans is risen. Can speak that item connected with medical treatment is more serious in the importance aspect among them Therefore, many-sided effort is consisting to ready countermeasure in reply, but economical method is not presented clearly as being realistic yet. Also, medical treatment service that more users through diffusion of fast internet are little more better effort that serve consist. But, in the case of old age, by difficulty of the use, restriction condition happens. In this paper proposed system that is prevailing already and user-friendly can cope curtly in old mans' emergency situation more rapidly and conveniently using mobile phone of CDMA way relatively.

IP VPN의 사용은 현재 보편화 되었고 네트워크 장비의 통합 추세에 따라 IP VPN과 방화벽 통합제품의 생산이 활발히 이루어지고 있다. 통합 보안 제품은 비용 효율성과 관리의 편리성, 확장성, 유연성과 같은 장점을 제공하지만 높은 성능 지원을 요구한다. 방화벽의 성능 인자의 하나로서 정책의 개수는 그 수에 비례하여 검색 시간이 지연되는 문제를 발생시키고, 이러한 성능 저하 문제는 VPN과 통합 시 더욱 가중된다. 더욱이 차세대 네트워크인 IPv6로 환경에서는 IP의 비트수가 증가하여 검색 성능 문제 해결이 필수적으로 요구된다. 본 논문에서는 이러한 통합 제품의 검색 성능 문제에 관한 해결 방안으로 IPv6 주소의 특성을 사용한 메커니즘을 제안한다. 제시한 메커니즘은 보안 정책 테이블의 주소 필드를 IPv6 주소에 포함된 인터페이스 식별자로 대체하여 보안 정책 테이블의 검색 속도를 향상시키는 방법이다. 이 방법은 차세대 네트워크 환경에서 주목 되고 있는 보안 및 성능 문제에 대해 큰 역할을 할 것으로 기대된다.

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.

In this paper, we propose the architecture of the policy-based emergency bio data transmission for the smart healthcare service. the medical staff can quickly and accurately monitor the emergency bio data of the remote patient through the proposed architecture. The proposed system consists of three parts: IEEE 11073-based agents and managers performing the aggregation function and transmission function of the bio data; the emergency management server performing the converting function between IEEE 11073 and HL7 and auto-diagnosis function of the policy-based; HL7 medical system based on HL7. Finally, by implementing the proposed system, we shows that the aggregation of the bio data and management of the emergency bio data in the smart healthcare service are possible.

Falling situations are extremely critical events for the elderly person who requires timely and adequate emergency service. For the case of emergency, the information of falling and its direction can be used as an important information for the first aid treatment of the injured person. In this paper, a falling detection system which can pinpoint the falling event with the falling direction is implemented. In order to detect the fall situation, a single gyroscope (MPU-6050) is used in the developed system. The fall detection algorithm that can classify 8 different fall directions such as front, back, left, right and in between falls is proposed. The direction of the fall is decided by examining the acceleration values of X and Y directions of the sensor. It is shown that the proposed algorithm successfully detects the falling event and the falling direction with probability of 97% for a selected value of acceleration threshold.

Wireless sensor network-related application system can perform functions such as environmental pollution monitoring, building control, home automation in future. In this paper, we present wireless sensor network based system for subway station in order to reduce the damage of the people and the subway station due to fire. Sensor nodes in this system can sense temperature, illumination, smoke, and human body in real time and detect the accident in the subway station. These real-time sensing and wireless networking minimize casualties and damage to property.

본 논문에서는 센서 네트워크를 이용해서 환자 모니터링 시스템(PVMS : Patient Vital Sign Monitoring System)을 구현하였다. 최근 의료 서비스에 유비쿼터스 컴퓨팅 기술을 적용한 사례들이 늘고 있다. 기존 사례에서는 센서 전지 수명, 이동 통신비, 응급상황 대처 등 개선할 부분이 존재한다. 본 연구에서는 이런 점들을 해결하기 위해 환자의 체온 및 맥박 생체신호를 측정하기 위해 소형센서를 사용하였다. 또한 생체신호 전달을 위해 초저전력 무선통신 노드를 사용하여 언제 어디서나 환자 모니터링이 가능하고 의료진에게 응급상황을 신속하게 전달할 수 있는 웹기반 시스템을 개발하였다. 본 연구의 결과는 병동환자뿐만 아니라 활력증후를 상시로 모니터해야하는 원거리 환자를 위한 의료시스템 구축에도 활용될 수 있을 것이다.

Objectives: The purpose of this study was to define the underserved emergency medical services (EMS) areas in Daejeon metropolitan city, as well as to identify their distinctive characteristics in public health perspectives. Methods: An underserved EMS area was operationally defined as an area in which it is difficult to arrive at an emergency medical center within 30 minutes. Using a cost-weighted distance algorithm with a geographic information system (GIS), the underserved EMS area was calculated. The characteristics of the underserved areas were analyzed by the Chi-square test. The SPSS statistical software package was used to perform the statistical analysis. All statistical tests were two-sided, and a p-value<0.05 was considered statistically significant. Results: Twelve administrative sectors ('Dong' in Korean) were included in the underserved areas, accounting for a population of approximately 8,100 citizens. The relationships between underserved EMS area and populations of agriculture, fishery, and forestry; citizens who are recipients of national basic livelihood security program; disabled; or aged 65 or older were statistically significant. Conclusion: It was found that 12 administrative sectors were included in the underserved EMS areas. Revealing underserved EMS areas using GIS analysis based on a cost-weighted distance algorithm of road data was an effective analytic method. However, as this study was confined to Daejeon City, South Korea, a nation-wide study should be performed to provide a more accurate conclusion.
