With the development of recent IT is spreading and dissemination of smart terminals, telemedicine and electronic medical records (EMR) and other common anywhere due to medical advances are being digitized environment. This trend is in line with the information to take advantage of smart terminals in the mobile medical information system increasing. In this paper, the recent trend to examine healthcare information technology standardization, predicting the future prospects look healthcare information systems. In addition, the security of mobile medical information system, to look at aspects of mobile-based health information systems in the country's need to discuss the trends and standards.

In addition to the rapid development of health information technology services for the development of new medical information, a lot of research is underway. Improve health care services for patients are many ways to help them. However, no information about the security, if only the technology advances in health care systems will create an element of risk and threat. Today's issues and access issues are stable over a public network. Ad hocsensor network using secure, non-integrated health information system's security vulnerabilities does not solve the security vulnerabilities. In the development and utilization of health information systems to be subject to greater restrictions. Different security policies in an environment with a medical information system security policy mechanism that can be resolved if people get here are needed. Context-aware and flexible policy of integration and confidential medical information through the resistance should be guaranteed. Other cross-domain access control policy for telecommunications should be protected. In this paper, that the caller's medical information system, diversification, diversification Security agent in the environment, architecture, design, plan, role-based security system are proposed. The proposed system architecture, design work in the field and in the utilization of one model are expected to be.

The strength of our country is based on high-speed networks to build a nationwide health information network to improve the quality of health care is needed. However, nature of the medical services in the hospital medical record form, so that all departments characterize each medical department, a common format that can be used for all disease is a very difficult challenge. This study is one of the ways to improve this priority issue on health information sharing medical information system(PACS/HIS) information linkage between the problem of information, compatibility and security issues derived. The problem is derived from the requirements of theorem 3 to 6 items. This is effective in order to improve sharing of medical information for the purpose of designing the software system. Sharing of medical information software system design are derived from stakeholders, requirements analysis, architecture design, software framework, configuration, architecture evaluation process. This study is based on the medical information standardization environmental diagnosis of a medical information system design. Software design philosophy is based on a new framework for deriving the function and mechanism made up.

U_Life의 의료 기술은 의료 영상 정보 전송 서비스를 언제 어디서나 가능하게 해준다. 더 나아가 의사의 다양한 상황인식을 인지, 수집하고 변화된 상황에 적합한 최적의 영상 정보를 의사에게 전송해주는 지능적인 서비스가 필요하다. 본 논문에서는 의사의 변화된 상황에 적합한 서비스를 제공하고자 의료영상 정보 전송 시스템에 상황인식 서비스를 접목시킨 의사 중심의 의료 영상 정보 전송 미들웨어(Doctor Centered PACS Middleware) 시스템을 제안하고자 한다.

Recently, A utilization request of the U-Healthcare services are increasing rapidly. This is because the increase in smartphone users and ubiquitous computing technology was developed. 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.

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.

In this paper, we designed a role-based emergency medical information security system REMISS added the security concept to the existing emergency medical information system. Also we suggested a REMISS protocol based on HL7 for using the emergency medical information and the security information. The procedure of security consists of user authentication phase and role/permission assign phase in the REMISS. The REMISS can supply proper security service since the REMISS assign proper permissions to each users of emergency medical information system and allow the user to access the permitted emergency medical information by using security information of the REMISS. There are some advantages that REMISS can adapt to the changing of the role of each user by dynamic exchanging the security information and assigning permissions to each user.

Healthcare costs are continuously increasing due to longer life expectancy and providing global healthcare services through medical tourism is new service growth engine for Korea. Several countries have well established programs and infrastructure dedicated to medical tourism. South Korea is attempting to become a major player in this domain by undertaking broad initiatives. The success of medical tourism is greatly impacted by easy access to two types of information, namely, medical and travel information. The National Health Insurance System in Korea collects huge amount of clinical and financial information from all hospitals. However, this information does not get used effectively in health and travel information systems to support medical tourism. This paper provide clear process map of medical tourism to understand how the patient and information process both medical and tourism fields also describe the need of customer and service provider. In this paper, we develop a medical tourism service system that will promote information exchange and service delivery.

The integrated medical information system is an effective medical diagnosis assistance system which offers an environment in which medial images and diagnosis information can be shared. Because of the large-scale medical institutions and their cooperating organizations are operating the integrated medical information systems, they can share medical images and diagnosis information. However, this system can only stored and transmitted information without other functions. To resolve this problem and to enhance the efficiency of diagnostic activities, a medical image analysis system is necessary. In this paper, the proposed relationship method analyzes medical images for features generation. Under this method, the medical images have been segmented into several objects. The medical image features have been extracted from each segmented image. Then, extracted features were applied to the Relationship Method for medical image analysis. Several experimental results that show the effectiveness of the proposed method are also presented.
