Nowadays there are many studies and there's huge development about RFID and WSN which have great developmental potential to many kinds of applications. In particular, the healthcare field is expected to could be securing international competitive power in u-Healthcare and combined medical treatment industry and service. More and more real time application apply RFID and WSN technology to identify, data collect and locate objects. Wide deployment of RFID and WSN will generate an unprecedented volume of primitive data in a short time. Duplication and redundancy of primitive data will affect real time performance of application. Thus, emerging applications must filter primitive data and correlate them for complex pattern detection and transform them to events that provide meaningful, actionable information to end application. In this paper, we design a complex event processing system. This system will process RFID and WSN primitive data and event and perform data transformation. Integrate RFID and WSN system had applied each now in medical treatment through this study and efficient data transmission and management forecast that is possible.

본 논문에서는 사용자들의 생체 신호를 수집하여 해당 데이터를 서버에 저장하고 이를 모니터링 할 수 있는 시스템을 구현 하였다. 기존에는 모니터링을 위해 별도로 측정된 결과를 분석하고 확인할 수 있도록 하는 고정된 장치가 필요했다. 하지만 본 논문에서는 사용자가 무선 센서를 소지하고 있으므로 각각의 데이터를 실시간으로 측정하며 사용자는 일상생활에 지장 없이 활동이 가능하다. 측정된 정보는 웹에서 연람할 수 있도록 하여 별도의 장치가 필요하지 않다. 기존의 방식보다 간편한 모니터링 시스템을 구축하고자 한다.

WBAN(Wireless Body Area Network)기반의 의료 응용으로 실시간 모니터링 시스템을 구현하였다. 특히 산소포화도 생체 센서들로부터 연속적으로 전송되는 스트림 데이터에 대해 다양한 조건을 포함하는 질의들이 실행 되는데 이러한 실시간 모니터링 질의들을 효율적으로 식별하기 위한 질의 인덱스를 설계하였다. 매번 모든 질의들을 실행하기에는 시간이 많이 걸리기 때문에 Interval Skip List 를 이용하여 빠르고 효율적으로 식별하도록 설계하였다. 이로써 위급한 상황의 환자의 건강에 문제가 생겼을 때 신속하게 대처할 수 있는 환경을 제공한다. 본 논문에서는 방대한 양의 스트림 데이터와 이 데이터를 실시간으로 감시할 수 있도록 Interval Skip List 를 스마트 메디컬 스페이스(m-MediNet)에 적용한 방법을 기술하고 있다.

The u-health service is using portable device such as smart device and it consists of small computing device. The u-health service carry out same performance with desktop computer. We designed message structure based on Bluetooth HDP. This message structure is used to transmit patient's biometric data on the smart device of medical team, patient and family over the mobile network environment. ISO/IEEE 11073 PHD standard was defined based on the method of communication between the agent and the manager. And We are confirmed the reliable transmission of biometric data at the smart device by implementing the android OS based patient information monitoring application to check the status of patient for medical team, patient and family.

코로나19 팬데믹을 계기로 원격의료의 수요가 폭발하여 비대면 진료가 가능하도록 법률을 개정하려는 추세에 필요한 서비스로 시간과 비용이 없고, 거리 두기 단계 상향등으로 병원에 방문하지 못하는 환자가 늘어나고 있다. 하지만 시중에 건강상태를 확인할수 있는 장비를 판매하지만 전문적인 지식이 없는 일반인은 정확하게 결과를 알 수 없고 한가지의 검사만 측정이 가능하기 때문에 검사결과를 확인하고 싶으면 병원을 방문해야한다. 본 논문은 전문적인 지식이 없는 일반인도 자신의 건강상태를 확인가능하게 하기 위해 심박, 심전도, 산소포화도, 체온센서의 측정값을 그래프로 표현한 후 검사결과를 토대로 의사와 원격진료가 가능하여 병원을 방문하지 않고 의사와 상담 및 진료가 가능하다. 병원에 입원이 불가능한 환자일 경우 산소포화도 측정값이 95%미만이면 산소공급 즉 응급처치가 가능하다.

The usability evaluation of the remote fluid monitoring device, which was introduced to reduce the work of nurses and increase the efficiency, was performed due to the expansion of the non-face-to-face medical system. Remote fluid monitoring is a fusion of various technologies such as fluid measurement and analysis, error correction technology, and transmission technology. The range of use by users, the information they want to obtain, and the control device, etc. are wide, and the factors that evaluate the product are also diverse. Therefore, it is difficult to improve the product through evaluation. In this study, a quantitative index was developed to help improve the product for commercialization by conducting 20 usability evaluations in three areas of product stability, operability, and satisfaction with the remote sap monitoring system device. It was performed through infrared and load cell-type sap monitoring devices. In terms of stability, there was a difference in installation work such as fixing the pole of the device, and high satisfaction was shown for operability and accuracy. In terms of product satisfaction, the satisfaction of load cell devices was generally high.

In this paper we present two databases for two different systems each having novel implementation ideas: a u-Healthcare system with a mobile gateway and MAGI network monitoring system. u-Healthcare system is capturing and monitoring vital sign data without restrictions of location and time using body sensor network and a mobile gateway. MAGI is a system which has a dynamic firewall function and solves problems of existing traffic monitoring tools. In addition to presenting the design principles behind these two systems, we describe the respective database schemas together with detailed information of the data stored within the databases. We will also show and discuss performance measurements and calculations for both systems. Based on the performance data we will discuss the systems' suitability for their intended uses.

An electrocardiogram (ECG) is one of the most important biosignals, and in particular, continuous ECG monitoring is very important in patients with arrhythmia. There are many different types of arrhythmia (sinus node, sinus tachycardia, atrial premature beat (APB), and ventricular fibrillation) depending on the cause, and continuous ECG monitoring during daily life is very important for early diagnosis of arrhythmias and setting treatment directions. The ECG signal of arrhythmia patients is very unstable, and it is difficult to detect the R-peak point, which is a key feature for automatic arrhythmias detection. In this study, we develped a continuous measuring Holter ECG monitoring device and software for analysis and confirmed the utility of R-peak of the ECG signal with MIT-BIH arrhythmia database. In future studies, it needs the validation of algorithms and clinical data for morphological classification and prediction of arrhythmias due to various etiologies.
