As fusing IT and medical technique, the number of patients who adhere medical equipment inside of them is increasing. However there is a problem of for the third person to tap or modulate the patient's biometric data viciously. This paper suggests quantum encryption-based key distribution model to share key for the third person not to tap or modulate the patient's biometric data between patient and hospital staff. The proposed model uses one-time pad key that shares key sending random bits not direct sending message of quantum data. Also, it guarantees patient's anonymity because the biometric data of injected-device in the body doesn't be exposed unnecessarily.

The rapid aging is increasing as the shortage of medical facilities and the resulting of decline in the quality of public health. In order to ease the burden of rising medical expenses, advanced medical institutions are expanding their remote medical care to lower the cost of services. U-healthcare detects the changes in physical and chemical phenomena occurring in the human body and converts them into electrical signals that can be processed and feeds back to the results through analytical and visualization processes to select only the desired information from the measured signals. The service is provided through a process of providing an alarm to a user. However, traditional biometric methods of attaching sensors directly to the body can be annoying and rejected in daily life. Therefore, there is a need for a method of continuously measuring biometric information without causing inconvenience to daily life. In this paper, we propose an IR-UWB-based non-contact and non-responsive respiratory measurement system that can continuously monitor biological information without any inconveniences to daily life.

Health care services in a residential area would accelerate the aging in place. In addition, these changes would play a key role in terms of reducing healthcare costs and leading a healthy lifestyle. The purpose of this study draws the design methodology of community facilities and each dwelling with healthcare services in apartment complex, which the elderly people will enjoy a better health status. This paper presents the result focused on the welfare building in Gayang 7th apartment complex. The intention to receive healthcare services was investigated by occupants. Moreover, design requirements were drawn through in-depth interviews and the state observation to use the service. In the complex, stronger intention to serve the u-Healthcare services was shown to the pre elderly group than the elderly. Both of them had a problem to use and keep the health equipment due to the fact there is not enough space in the unit. Reporting the observation results, the upright-posture furniture attaching the healthcare equipment and the equipment storage should be prepared in the unit. In the public space, the program for these healthcare services can be divided into three parts, i.e. the health status measurement, the healthcare, and the service connected to the surrounding facilities. The health status measurement can be the basic to the health services and its function should be gradually extended. In the complex, the hybrid type with various functions could be applied owing to a new building for welfare; moreover, semi-independent user should be able to receive the home healthcare service.

Body insertion due to the recent development of sensor technology, the device is attached patients to receive medical services from anywhere, anytime environment is changing. Body insertion devices for the hospital, the patient's vital information attached personnel (doctors, nurses, pharmacists, etc.) to pass, however, when a problem occurs, a patient's information to a third party that can be exploited easily exposed. In this paper, we proposed signature authentication protocols mandate based on the patient's power of attorney from the center of the u-Healthcare services, hospital officials FormHelper third party disguised as a patient, the hospital patient information easily obtained from the officials to prevent. The proposed protocol, the patient's sensitive information to a third party, do not expose the patient's sensitive information to the random number generated by the u-Healthcare service centers and patients hash signature key to encrypt sensitive information of patients. From third parties to maintain synchronization between the patients and the hospital personnel in order to prevent patient information from being exploited illegally by the patient's vital information leakage can be prevented.

This paper suggests U-healthcare system for individual health management realizing the gateway, client, and Java-based network server by using the vital signal measuring system and android-based mobile platform. This study realized the vital signal measuring system based on the technology to measure the ECG, oxygen saturation, blood pressure, and respiration, etc. And all the information of measurement was transmitted to the mobile gateway using the 3-bite transmission protocol consisting of headers and data. The data transmitted to the mobile gateway was used to examine the mobile client's personal health indexes through the network server. This paper realized and tested the android-based gateway, client, and the broadcasting network server and verified their validity with simulations and actual humans. As a result, the U-healthcare system suggested was proved to be effective in managing each individual's health from short distance and long distance. And it could examine each individual's health conditions in real-time and was found to be advantageous in that it could secure the guardian's mobility.

Purpose: We analyzed the need for home care services and awareness of U-healthcare in nurses of the Catholic Parish Home Care Center to link the ubiquitous health care system and the home care. Methods: We recruited 46 nurses from a home care center in the catholic parish of the C medical center from April 4th to June 8th, 2007. Results: The highest needs were 'assessment and diagnosis of the problem', 'management of hypertension & diabetes patients', 'counseling of the patient', and 'counseling of major caregiver and family problems'. Therapeutic nursing showed the highest needs in bedsore care. Nurses want hospital medical records available through the ubiquitous health care system. Conclusion: Home care services are supported from the agency, with high needs in assessing and diagnosing the problem, counseling, and managing of hypertension & diabetes patients. Education and public relations efforts on the U-healthcare system should improve system awareness.
