Today, the medical information system has evolved in the way of integrated healthcare IT information systems. Therefore, it is trying to build advanced U-Healthcare service. Though the U-Healthcare environments is exchanged the information between systems in many cases, however since the each system is different, the integration and exchange of data is difficult. To overcome this problem, in this paper it proposes that we suggests a possible DBaaS(DataBase as a Service) for the heterogeneous integration of medical information management and data exchange. First, the proposed system builds DBaaS cloud by integrating the meta-DB Schema level and DB Schema for each hospital. And, the mapping the schema data and the existing hospital information system is possible using the International Standard HL7. By applying the proposed method to the hospital system, it comes true the efficient exchange of information between the patients, doctors, staffs through the data mapping of the one to multi-system.

Furthermore, the demand for access to and use of medical information systems is growing rapidly with a smartphone. This system have the advantage such as they can access from anywhere and anytime in the healthcare information system using their smartphone quickly and easily. But this system have various problems that are a privacy issue, the location disclosure issue, and the potential infringement of personal information. this problems are arise very explosive. Therefore, we propose a secure information security system that can solve the security problems in healthcare information systems for healthcare workers using smartphone. Our proposed system, doctors record, store, modify and manage patient medical information and this system would be safer than the existing healthcare information systems. The proposed system allows the doctor to perform further authentication by transmitting using SMS to GOTP message when they accessing medical information systems. So our proposed system can support to more secure system that can protect user individual information stealing and modify attack by two-factor authentication scheme. And this system can support confidentiality, integrity, location information blocking, personal information steal prevent using cryptography algorithm that is easy and fast.

Various studies on individual health-care application services have been lively going on due to recent development of information and communication technology and improvement of life quality. Moreover, U-health care area is emerging as a new growth industry as the demand of U-health care service for a quality life grows with the development of medical technology and ubiquitous environment. U-health care system for crew members on ships, who need to spend much time on sea far from their families, is especially needed because they find their job much more stressful not only physically but also mentally than any other people in different jobs do and have less chance to get proper medical services in time. In this paper, we suggested how to get more accurate and objective U-health wellbeing index by complementing SF-36, the general heath care index model in order to managing health of crew.

Pulse wave is the physiological responses through the autonomic nervous system such as ECG. It is relatively convenient because it can measure the signal just by applying a sensor on a finger. So, it can be usefully employed in the field of U-Healthcare. The objects of this study are acquiring the PPG (Photoplethysmography) one of the way of measuring the pulse waves in non-invasive way using the CMOS image sensor on a smartphone camera, developing the portable system judging stressful or not, and confirming the applicability in the field of u-Healthcare. PPG was acquired by using image data from smartphone camera without separate sensors and analyzed. Also, with that image signal data, HRV (Heart Rate Variability) and stress index were offered users by just using smartphone without separate host equipment. In addition, the reliability and accuracy of acquired data were improved by developing additional hardware device. From these experiments, we can confirm that measuring heart rate through the PPG, and the stress index for analysis the stress degree using the image of a smartphone camera are possible. In this study, we used a smartphone camera, not commercialized product or standardized sensor, so it has low resolution than those of using commercialized external sensor. However, despite this disadvantage, it can be usefully employed as the u-Healthcare device because it can obtain the promising data by developing additional external device for improvement reliability of result and optimization algorithm.
