Consistently collecting a variety of vital signs is crucial in u-Healthcare. In order to do so, IoT is being considered as a top solution nowadays as an efficient network environment between the sensor and the server. This paper proposes a transmission method and compression algorithm which are appropriate for IoT environment. Results were compared to widely used compression methods, and were compared to other prior researches. The results showed that the compression ratio of our proposed algorithm was 11.7.

A u-healthcare remote diagnosis system is proposed for chronic disease and medical vulnerable groups check the health systematically and support for the most optimal environment to improve the quality of life. The u-healthcare remote diagnosis system using wireless measure the thoracic sound in the chest. And this is demonstrated that the system using radio frequency is not be affected by the electromagnetic wave with the use of an experiment and by confirming that this u-healthcare remote diagnosis system can not affect the doctors and the patients.

The Ubiquitous Healthcare business are growing recently by medical service development. According to this environment, many healthcare service model have been studying and suggested. At the same time, medical world market has been reorganized into a traditional medical science out of the west medical science. But in spite of this trend, domestic U-Healthcare market in traditional medical science is for lack of profit service model. So it is true that the presentation is demanded from oriental medicine U-Healthcare service model these days in oriental field. Thus, in this paper we propose the healthcare service model that can be applied to the oriental field efficiently. Our method is based on fuzzy rule method that analyze the patient data by CDSS processing. In experiment, proposed method is more profitable and efficient than west service model. For future works, we will research about the standardization and security of processed data.

When unapproved users access to healthcare system and use medical information for other malicious purposes, it could severely threaten important information related to patients' life, because in ubiquitous environment healthcare service makes patient's various examination results, medical records or most information of a patient into data. Therefore, to solve these problems, we design RBAC(Role Based Access Control) for U-healthcare that can access control with location, time and context-awareness information like status information of user and protect patient's privacy. With implementation of the proposed model, we verify effectiveness of the access control model for healthcare in ubiquitous environment.

Healthcare systems around the world are struggling to cope with the pressures of rising costs, aging populations, and decisions about how to allocate and pay for seemingly limitless advances in high-technology medical procedures. Today healthcare environments are also changing greatly in Korea. The United States healthcare is being reinvented by reducing the costs and bringing service close to the consumer, and multi-strategies are being used to strive in the market driven shift. This study is aiming to get the lesson and direction of the future healthcare facilities in Korea by analysing the past and current trends of healthcare facilities in U.S..

Due to the convergence between digital devices and the development of wireless communication technology, bit-signal sensor miniaturization, building an Electronic Medical Record (EMR) which is a digital version of a paper chart that contains all of a patient's medical history and the information of Electronic Health Record (EHR), Ubiquitous healthcare (u-Healthcare) that can monitor their health status and provide personal healthcare service anytime and anywhere. Also, the appearance of cloud computing technology is one of the factors that accelerate the development of u-healthcare service. However, if the individual information to be used maliciously during the u-healthcare service utilization, leads to serious problems directly related to the individual's life because if it goes beyond the level of simple health screening and treatment, it may not provide accurate and reliable healthcare services. For this reason, we analyzed a variety of security issues related to u-healthcare service in cloud computing environment and described about directions of secure health information sharing system construction. In addition, we suggest the future developmental direction for th activation of u-healthcare industry.

In this paper, we propose the active model based on the distributed object group framework which provides adaptive information sharing service to support it to various Healthcare home service. And we applied it to Healthcare home service. This proposed model provides information that collected from physical environment of the home network and sensors for healthcare service according to situation of the user. We uses information of the healthcare information database which was constructed previously, and we uses TMO scheme for to solve each other different periodic qualify. We uses information of the healthcare information database which was constructed previously, and we uses TMO scheme for to solve each other different periodic quality. Specialty, We wrote about interaction of various Healthcare Home services for adaptive information services, and wrote about u-healthcare framework based on DOGF. Finally, we apply active model to healthcare monitoring service, and we showed its result and performance evaluation.

Healthcare is a research field suitable for applying the recent ubiquitous techniques. As a test system, we developed a kind of CDSS (Clinical Decision Support System) running in ubiquitous environment. called as 'uCDSS'. The uCDSS is a core system of the ubiquitous healthcare and is composed of some 'uMLMs(Ubiquitous Medical Logic Modules)'. The uMLMs based on the class in C# programming language could be reused in development of CDSS, or another EHR system running in .NET environment. As a test system, we developed the DM(Diabetes Mellitus knowledge system using ASP.NET. This system shows the potential of C# class-based uMLMs and the extensibility to any .NET development project.

The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. In particular, we address the communication security issues of access sharing of health information resources in the ubiquitous healthcare environment. The proposed scheme resolves the sender and data authentication problem in information systems and group communications. We propose a novel key management scheme for generating and distributing cryptographic keys to constituent users to provide form of data encryption method for certain types of data concerning resource constraints for secure communications in the ubiquitous healthcare domains.
