The characteristics of today's health care industry, based on the state of the art IT can be represented as a paradigm of human-oriented ubiquitous and accessible as possible by U-Health care. In addition, the healthcare industry is information and communication technologies (ICT) developments regarding the many advances and applications based on the research being carried out actively. Medical information system has been developed toward combining information systems of medical IT and it sets its sights on the fusion of developed IT and u-healthcare system. So changing distributed medical information systems into a safe PHR integrated system based on IaaS cloud computing is suggested in order to forge u-healthcare system with the times in this paper. Our experimental results show that our proposed system increased the data access time by about 24% and reduces the waiting time for processing service by about 4.3% over the web-based PHR.

Ubiquitous health care system, which is one of the developing solution technologies of IT, BT and NT, could give us new medical environments in future. Implementing health information systems can be complex, expensive and frustrating. Healthcare professionals seeking to acquire or upgrade systems do not have a convenient, reliable way of specifying a level of adherence to communication standards sufficient to achieve truly efficient interoperability. Great progress has been made in establishing such standards-DICOM, IHE and HL7, notably, are now highly advanced. IHE has defined a common framework to deliver the basic interoperability needed for local and regional health information networks. It has developed a foundational set of standards-based integration profiles for information exchange with three interrelated efforts. HL7 is one of several ANSI-accredited Standards Developing Organizations operating in the healthcare arena. Most SDOs produce standards (protocols) for a particular healthcare domain such as pharmacy, medical devices, imaging or insurance transactions. HL7's domain is clinical and administrative data. HL7 is an international community of healthcare subject matter experts and information scientists collaborating to create standards for the exchange, management and integration of electronic healthcare information. The ASTM specification for Continuity of Care Record was developed by subcommittee E31.28 on electronic health records, which includes clinicians, provider institutions, administrators, patient advocates, vendors, and health industry. In this paper, there are suggestions that provide a test bed, demonstration and specification of how standards such a IHE, HL7, ASTM can be used to provide an integrated environment.

In this study, we developed a feasible structure of a textile-based inductive sensor using a machine embroidery method, and applied it to a non-contact type vital sign sensing device based on the principle of magnetic-induced conductivity. The mechanical heart activity signals acquired through the inductive sensor embroidered with conductive textile on fabric were compared with the Lead II ECG signals and with respiration signals, which were simultaneously measured in every case with five subjects. The analysis result showed that the locations of the R-peak in the ECG signal were highly associated with sharp peaks in the signals obtained through the textile-based inductive sensor (r=0.9681). Based on the results, we determined the feasibility of the developed textile-based inductive sensor as a measurement device for the heart rate and respiration characteristics.

With the increasing number of chronic disease patients, the importance of everyday health care has grown more significant. The study researchers expected it would help for patients' health improvement and healthcare service expansion if users check their vital signs in their daily lives and send the results to a medical center's servers through a specific device automatically. This thesis, in line with this idea, seeks to develop a portable healthcare gateway. The gateway is designed in a USB type and can transmit standardized data, operating regardless of a user's location and Personal Healthcare Devices (PHDs). The developed portable healthcare gateway provides effective services in ubiquitous environments to customers, which will improve the health of chronic patients.

Objectives: To examine survivorship disparities in demographic factors and risk status for non-muscle-invasive bladder cancer (NMIBC), which accounts for more than 75% of all urinary bladder cancers, but is highly curable with early identification and treatment. Methods: We used the US National Cancer Institute's Surveillance, Epidemiology, and End Results registries over a 19-year period (1988-2006) to examine survivorship disparities in age, sex, race/ethnicity, and marital status of patients and risk status classified by histologic grade, stage, size of tumor, and number of multiple primary tumors among NMIBC patients (n=29 326). We applied Kaplan-Meier (K-M) and Cox proportional hazard methods for survival analysis. Results: Among all urinary bladder cancer patients, the majority of NMIBCs were in male (74.1%), non-Latino white (86.7%), married (67.8%), and low-risk (37.6%) to intermediate-risk (44.8%) patients. The mean age was 68 years. Survivorship (in median life years) was highest for non-Latino white (5.4 years), married (5.4 years), and low-risk (5.7 years) patients (K-M analysis, p<0.001). We found significantly lower survivorship for elderly, male (female hazard ratio [HR], 0.96), Latino (HR, 1.20), and unmarried (married HR, 0.93) patients. Conclusions: Survivorship disparities were ubiquitous across age, sex, race/ethnicity, and marital status groups. Non-white, unmarried, and elderly patients had significantly shorter survivorship. The implications of these findings include the need for a heightened focus on health policy and more organized efforts to improve access to care in order to increase the chances of survival for all patients.

Based on the rapid development of the computer network technology, the ubiquitous sensor network (USN) was developed to enable us to have access to the communication environment anywhere and anytime without the need for recognizing computers or networks. Moreover, with the increasingly high interest on individual health, the USN technology is being applied to diverse sectors for healthcare and disease prevention. In this paper, a system was designed and implemented using the USN-based RF communication for doctors and nurses who care patients in the hospital to easily measure and control the physiological data on blood pressure and blood sugar. In addition, a database was designed using MS SQL database to store and manage the blood pressure and blood sugar data, which were passively or actively measured from patients. Using the results of this study, the physiological data of patients can be managed in real time and emergency situation can be instantly addressed. It is expected that the healthcare service can be improved and the paradigm of healthcare service environment can be changed.

Purpose: The purpose of this study was to investigate the effectiveness of an educational intervention that used both cellular phones and the Internet to provide a short messaging service (SMS) relating to blood glucose, blood pressure, and serum lipid levels in postmenopausal women with impaired fasting glucose (IFG). Methods: Twenty-eight postmenopausal women were assigned to an intervention group and twenty-one postmenopausal women to a control group. The intervention was provided for 12 weeks. Patients in the intervention group were asked to access a web site by using a cellular phone or to use the Internet directly and input their blood glucose and blood pressure levels weekly. Participants were sent the optimal recommendations weekly by both cellular phone and Internet. Results: The intervention group had a mean decrease in systolic blood pressure (SBP) level of 8.1 mmHg but changes for the control group were not significant. There was a significant mean change in diastolic blood pressure (DBP) level for the intervention group (-7.7 mmHg). The mean change in the control group was not significant. Conclusion: This educational intervention using the Internet and a SMS by cellular phone improved levels of SBP and DBP in postmenopausal women with IFG.
