Interoperability has been deemphasized from the hospital information system in general, because it is operated independently of other hospital information systems. This study proposes a future-oriented hospital information system through the design and actualization of the HL7 clinical document architecture. A clinical document is generated using the hospital information system by analysis and designing the clinical document architecture, after we defined the item regulations and the templates for the release form and radiation interpretation form. The schema is analyzed based on the HL7 reference information model, and HL7 interface engine ver.2.4 was used as the transmission protocol. This study has the following significance. First, an expansion and redefining process conducted, founded on the HL7 clinical document architecture and reference information model, to apply international standards to Korean contexts. Second, we propose a next-generation web based hospital information system that is based on the clinical document architecture. In conclusion, the study of the clinical document architecture will include an electronic health record (EHR) and a clinical data repository (CDR), and also make possible medical information-sharing among various healthcare institutions.

For the sharing and exchange of information between medical clinics, the clinical document has to be built on a standardized protocol such as a HL7-CDA. But it is difficult to exchange information between medical clinics because clinical document such as electronic medical record that include text and image, have different structure of document and type of expression. In this paper, we propose the electronic medical record system based on HL7-CDA that can share and exchange clinical information between medical institute. For this purpose, we have to design the schema of the clinical document architecture after we select the essential items of medical record and define templates. The proposed system can minimize integrating process and save parsing time when clinical information exchange and refer, by converting electronic medical record to base64 encoding scheme and integrate it in a XML document.

The purpose of this study is to develop a healthcare service based on standard protocol and information communication technology for mother's sustainable postpartum care. The developed service was consisted of a client area where mothers measure, manage and transmit their vital signs using their own smartphone and personal health devices, and a server area that manages and shares with the received mother's vital signs and the results of examination results and personal health records. The client area collects vital signs through the IEEE 11073 Personal Health Device (PHD) using the m-health application of the previous study and Continua Health alliance certified personal health devices and transfers to Health Level Seven (HL7) V2.4, Continuity of Care Record (CCR) and Continuity of Care Document (CCD). The server area consists of a mobile web that manages and shares the HL7 Fast Healthcare Interoperability Resources (FHIR)-compliant personal health records to ensure interoperability of examination results, and a mobile web where the postpartum caregiver enters and manages the results of the mother's examination results and provides it to the mother. In this way, the healthcare service of this study securing continued exchanges between the mother and postpartum caregiver improves the quality of life of the mother not only to satisfy the needs of the mother who was discharged but also through self-management and postpartum. In the future, we will conduct a study applying mothers and postpartum caregiver after approval of a clinical trail at a university hospital to evaluate developed healthcare services.

Active studies are under way on telemedicine and medical support based on mobile devices in order to vitalize U-Healthcare. Especially when the medical law is revised to allow a remote prescription system, studies on a mobile prescription system will rapidly increase. And yet since mobile apps have less compatibility due to the nature of mobile platform, there is a restriction that they have to be redeveloped to be compatible with the platform. To compensate this problem, this study designs a mobile web prescription interface by using HLTML5, the standard language of mobile web development and jQuery Mobile, a JavaScript Library. It also adds a feature of converting to a form of standard protocol HL7-based messages to share data with existing hospital information system. This interface makes it possible to be interlocked with the existing hospital information system through the transmission of the HL7 messages. The advantage of the proposed system is that it can be used in various environments since it is independent of mobile platforms and compatible with general computers.

Recently, as the technology has been blended with IT, BT or NT and technology in each field has been developed progressively with the people's needs for a healthy and abundance life. In the medical service field as well, related technologies such as medical equipment, medical information system, or medical business application have come to be diversified and advanced. However, most of these medical technologies are being developed independently without an interaction with other medical institutions or related companies, which causes many problems in the integration or interchangeability of them. This paper is intended to solve the problems generated during a direct information sharing between the functional interfaces of the present healthcare information sharing system. This paper develops a repository between the interfaces, which can save all the healthcare information from the institutions, and convert and publish it in various forms of document. In other words, recently HL7 protocol has been used for sharing the healthcare information in order to save the information in XML format, and develops the H-DISS(Healthcare-Documents Integrated Sharing System), a repository to manage and publish the saved document.

Mobile Health (M-Health) system is a recent term for medical and public health practice supported by mobile devices, such as mobile phones, PDAs, and other wireless devices. Mobile Health system has been successfully establishing at few general hospital in Korea. However, to use diverse devices manufactured by various company cause inoperability, and lack of security disappoints customers often. Although the outstanding health environment, most of hospitals are unavailable to share electronic patient records due to lack of standard protocol to handle the interoperability each other. Health Level 7 (HL7) is the best solution for the problem. In this paper, we will analyse a current M-Health service in terms of security and mobile device, and suggest iPhone for the best device against hospital environment. Also, for keep confidentiality of health information and patient privacy, enhanced security mechanism is introduced. As a consequence, interoperable standard, and most appropriate device for supporting staffs and M-Health performance, and enhanced securirty mechanism will be integrated in order to propose improved M-health model.

For efficient compatible system between medical clinics, the medical information has to be built on a standardized protocol such as a HL7 for text data and a DICOM for image data. But it is difficult to exchange information between medical clinics because the systems and softwares are different and also a structure of data and a type of code. Therefore we analyze a structure of DICOM file and design an integrated database for effective information sharing and exchange. The WISD system suggested in this paper separate the DICOM file transmitted by medical clinics to text data and image data and store it in the integrated DB(database) by standardized protocol respectively. It is very efficient that each medical clinic can search and exchange information by web browser using the suggested system. The WISD system can not only search and control of image data and patient information through integrated database and internet, but share medical information without extra charge like construction of new system.

현재 의료기관간의 의료정보 공유는, 상호 협의된 의료기관간 DICOM(Digital Imaging and Communication in Medicine) 및 HL7(Health Level 7)에서 제시한 표준 Protocol을 사용하거나 각 기관별 별도의 Protocol을 사용하고 있다.[1] 현재의 의료정보공유는 특정 의료기관들 끼리만 이루어지며, 해당 기관 간 전송구간 보안은 대부분 IPSec VPN을 적용하고 있다. 법적으로 요구되는 보안 요구사항을 만족하기 위해 사전 보안 제휴를 맺은 의료기관들만 의료정보를 공유하고 있기 때문인데, 이는 의료정보교류 범위를 제한하기 때문에 의료서비스의 발전을 보안이 저해하고 있다고 판단 할 수 있다. 본 논문은 의료정보공유 서비스와 의료정보 전송데이터 보호기술을 조사하여, 현재의 문제점을 확인 후 범국가적인 의료정보공유 서비스에 대한 전송데이터 보안 아키텍처의 수립을 지원하는데 그 목적이 있다.
