The purpose of this study is to measure both ECG and BCG(Ballistocariograph) signal of a subject on moving or resting wheelchair and detect the heart rate and respiratory rate and transmit an event message to remote server on emergent situation. To acquire ECG and BCG data, amplifier circuits were composed to be suitable for their characteristics. The output signals were converted to digital data and stored in bio-signal archiving media(SD card). CDMA module was used to transmit the event data on ECG electrode detachment and the received data was monitored by the developed C# application program. 5 volunteers participated in the experiment to evaluate the validity of the developed device. When the event occurs in each subject, 48 Kbyte data, stored for 32 seconds from that point, was transmitted to remote server through CDMA cellular phone network correctly. The received data of ECG, BCG, and 3-axial acceleration could be archived in server and the heart rate and respiratory rate could be measured and analyzed. The developed device in this study could acquire the ECG and BCG data of subjects on wheelchair simultaneously and measure their heart rate and respiratory rate. In addition, event data was verified to be transmitted to remote server without any errors.

Along with the aging of the population, the number of dementia patients is increasing, and the social and economic burden is also increasing. Currently, the effective way to manage dementia patients is to identify patients with dementia early. However, in rural and island areas where medical staff are scarce, there is a problem that it is difficult to visit a hospital and get an early examination. Therefore, we propose a remote early detection system for dementia to solve the problems. The remote dementia early diagnosis system is a system that allows a patient to receive examination and treatment from a remote dementia expert using remote medical technology based on real-time image communication. The remote early diagnosis system for dementia consists of a local client system used by medical staff at health centers in the island, an image server that transmits, stores and manages images, and an expert client used by remote dementia experts. The local client subsystem satisfies the current medical law's remote collaboration by allowing the patient to use it with the health center's medical staff. In addition, expert clients are used by dementia experts, and can store/manage patient information, analyze patient history information, and predict the degree of dementia progression in the future.

We have developed a remote diagnosis system using the LAN and MODEM which enables a routine check for a patient remotely. We used $LabVIEW^{TM}$ as the programing development tool and DAQ (Data Aquisition) board from National Instrument for data aquisition. The LAN card and MODEM are used for the transmission of patient's data. A patient data are aquired by DAQ board and signal processing is done by $LabVIEW^{TM}$, which is a graphical prgamming language. Two methods for the data of transmission. One is the Client-Server model using TCP/IP (Transmission Control Protocol / Internet Address) in the LAN (Local Area Network) Another is using MODEM to transmit the measured data from a patient. In this case, the data transmission is accomplished by the FTP (File Transfer Protocol).

A remotly controlled interactive magnetic resonance imaging (MRI) has been tried using the World Wide Web. For this purpose, an HTTP server is developed on the host computer of the MRI system. Video and audio conferencing capability is also included for the experiment. Using the developed system, MRI imaging has been successfully carried out at the Signal Processing Lab in the Kwangwoon University with the remote MRI system located at the Medical Image Research Center in the KAIST in Daejon.

Recently medical consumers pursue high leveled quality of life through active promotion, prevention, management activity of health as the importance of health during home life is emerged to meet the aging society and chronic diseases. In addition, people are directed to the m-Health for managing yourself their health by using smartphone and various personal health devices, if necessary transmits health data to the physician himself. In the previous studies, m-Health Application were developed and applied in the real clinical environment by adopting the medical information standards was rarely conducted. Therefore, in this study, the m-Health application platform was developed. Developed application was communicate with IEEE 11073 standard protocol using the Bluetooth Health Device Profile in personal health device via smart phone to process blood pressure information, and it converted to HL7 V2.6 ORU_R01 message for send to remote medical server. In addition, we tested the interoperability and safety of the developed application for 23 inpatient and 17 outpatient at D University Hospital. As a result, the blood pressure information has been transmitted without error.

Server and Pi view management, external image and internal image Copy Import business in PACS room is through the medical assistance. Import and Copy, and in particular the number of cases is increasing the number of import is a fast growing trend. Although the increase in workload With limited human resources to increase business efficiency so Remote system is using PACS room. This remote system will want to evaluate the effectiveness of using the service. Amount of data each 437.5 MB, Copy and Import time is to compare and evaluate sees by use 1 PC. 4 PC, 4 PC+ remote system. The use of the remote system before the January 2010 to June daily average waiting time and the use of the remote system after the January 2011 to June compared to a daily average patient waiting time, evaluate. Using the remote system in January 2011 to June Find out the average remote utilization. The biggest difference on the four copy and eight continued, Were performed two times faster by use 4 PC+ remote system than use 4 PC and four times faster than use 1 PC. Before using the remote system, the daily average wait time is 14.5 minutes after using the daily average 10.2 minutes, waiting time 30% of the existing waiting time was 4.3 minutes, to reduce. Using the remote system in January 2011 to June the average daily number of cases is 107 number and The number of remote and on average 35 cases with 32% in a day remote usage. The use of the remote system to Import, CD Copy and greatly increase the efficiency of their time could be. Hours due to efficiency could also reduce customer waiting time. As a result, the manpower and the use of a remote system over time to maximize efficiency in business hours, work was evaluated by.

U-Healthcare is a convergence service with medical care and IT which enables to examine, manage and maintain the patient's health any time and any place. For communication conducted in U-Healthcare service, the transmission methods are used that patient's medical checkup analysis results or emergency data are transmitted to hospital server using wireless communication method. At this moment when the attacker who executes the malicious access makes DRDoS(Distributed Reflection DoS) attack to U-Healthcare devices or BS(Base Station), various damages occur that contextual information of urgent patients are not transmitted to hospital server. In order to deal with this problem, this study suggests DRDoS attack scenario and countermeasures against DRDoS and converges with Big Data which could process large amount of packets. When the attacker attacks U-Healthcare devices or BS(Base Station), DB is interconnected and the attack is prevented if it is coincident. This study analyzes the attack method that could occur in U-Healthcare devices or BS which are remote medical service and suggests countermeasures against the security threat using Big Data.

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.
