  • According to the development of ubiquitous technologies, sensor networks is used in various area. In particular, medical field is one of the significant application areas using sensor networks, and recently it has come to be more important according to standardization of the body sensor networks technology. There are special characteristics of their own for medical sensor networks, which are different from the one of sensor networks for general application or environment. In this paper, we propose a hierarchical medical sensor networks structure considering own properties of medical applications, and also introduce transmission mechanism based on hierarchical structure. Our mechanism uses the priority and threshold value for medical sensor nodes considering patient's needs and health condition. Through this way Cluster head can transmit emergency data to the Base station rapidly. We also present the new key establishment mechanism based on key management mechanism which is proposed by L. Eschenauer and V. Gligor for our proposed structure and transmission mechanism. We use key provisioning for emergency nodes that have high priority based on patients' health condition. This mechanism guarantees the emergency nodes to establish the key and transmit the urgent message to the new cluster head more rapidly through preparing key establishment with key provisioning. We analyze the efficiency of our mechanism through comparing the amount of traffic and energy consumption with analysis and simulation with QualNet simulator. We also implemented our key management mechanism on TmoteSKY sensor board using TinyOS 2.0 and through this experiments we proved that the new mechanism could be actually utilized in network design.

  • In this paper, we proposes a emergency medical information system for predicting emergency situation by using the body's vital signs. Main research of existing emergency system has focused on body sensor networks. The problem of these studies have a delay of the emergency first aid since occurring of an emergency situation send a message of emergency situation to user. In the serious situation, patients of these problem can lead to death. To solve this problem, it need to the prediction of emergency situation for doing quickly the First Aid with identify signs of a pre-emergency situations until an emergency occurs. In this paper, the sensor network technology, the security technology, the internet information retrieval techniques, data mining technology, and medical information are studied for the convergence of medical information systems of the prediction of emergency situations.

  • 본 논문은 IT분야의 다양한 융합 기술 분야 중에서 언제 어디서나 사용자의 건강상태를 실시간으로 확인 할 수 있는 u-Health 시스템(Ubiquitous Health System)을 구현하였다. 현재 서비스되고 있는 u-Health 시스템은 초기 단계로 사용자의 상태를 확인하는 센서 기기에 의존하여 센서로부터 측정된 데이터를 가족 및 의료기관 등이 직접 분석하여 대처 하는 방법을 사용하고 있다. 그러나 기존에 개발된 u-Health 시스템은 센서 기기에 대한 오동작과 응급상황 발생 시 정확하고 신속한 대처를 할 수 없다는 단점을 가지고 있다. 따라서 본 논문에서는 u-Health 시스템의 단점을 보완하고자 기존 u-Health 시스템에 질환판별 알고리즘을 적용하여 사용자의 상태를 진단하고 이상 징후나 응급상황을 판단 할 수 있도록 하여 신뢰성을 높인다. 또한 질환판별 결과가 응급상황으로 판정될 시 가족 및 의료기관에 실시간으로 문자 메시지를 전송하여 알림 역할을 하고, 스마트폰과 웹페이지를 이용하여 실시간으로 사용자의 상태를 확인할 수 있도록 하여 신속성을 높이는데 목적이 있다.

  • 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.

  • With the recent establishment of a ubiquitous-based medical and healthcare environment, the medical information system for obtaining situation information from various sensors is increasing. In the medical information system environment based on context-awareness, the patient situation can be determined as normal or emergency using situational information. In addition, medical staff can easily access patient information after simple user authentication using ID and Password through applications on smart devices. However, these services of authentication and patient information access are staff-oriented systems and do not fully consider the ubiquitous-based healthcare information system environment. In this paper, we present a authentication service model based context-awareness system for providing situational information-driven authentication services to users who access medical information, and implemented proposed system. The authentication service model based context-awareness system is a service that recognizes patient situations through sensors and the authentication and authorization of medical staff proceed differently according to patient situations. It was implemented using wearables, biometric data measurement modules, camera sensors, etc. to configure various situational information measurement environments. If the patient situation was emergency situation, the medical information server sent an emergency message to the smart device of the medical staff, and the medical staff that received the emergency message tried to authenticate using the application of the smart device to access the patient information. Once all authentication was completed, medical staff will be given access to high-level medical information and can even checked patient medical information that could not be seen under normal situation. The authentication service model based context-awareness system not only fully considered the ubiquitous medical information system environment, but also enhanced patient-centered systematic security and access transparency.

  • In modern society, development of medical technology has extended the human life span. However, it has also caused some side-effects. Mostly old people who live alone are not available the medical service quickly when they are in emergency situations. Moreover heart related diseases as well are rapidly increasing with aging. This study proposes the emergency medical alarm system. This system measures the physiological signals such as ECG(electrocardiogram), temperature, and motion data, analyzes those data automatically, and sends the urgent message to the Emergency Medical Center and to their family. There are two main parts in the system. In the first part, physiological data acquisition part, the troublesome addition and deletion of body signals on existing proposed systems have been supplemented, which led to the modulized production by means of ECG sensor module, temperature sensor module, acceleration sensor module. The other part is mobile unit, which includes signal processing and transmission functions. And bluetooth allows two parts to communicate with each other. Data that are processed in the mobile unit are stored in the PC database through the WLAN using TCP/IP protocol.
