Abstract

U-healthcare is maintaining of users' health without limitations from where and when they are. As it is important to guarantee compatibility between heterogeneous systems in U-healthcare, a medical information standard is compulsory. An adequate standard means that it is easy to understand and it can cover wide range of information types and various medical devices. Among them, HL7(Helath Level 7) has those traits, but HL7 is not adequate for non-text message, especially for medical waveform. JAHIS suggested an appropriate standard, that is MFER. MFER has many advantages for representation of medical waveform, but it is still not good for real-time applications. In U-healthcare, there are lots of needs for real-time application, so we need a standard that can have useful properties of MFER and HL7, and support real-time. In this article, there are two main topics. The first one is introducing MFER and HL7. Second, the new scheme(TS-MFER with HL7) is developed by modifying MFER and HL7 for real-time applications.

U-healthcare 환경에서는 시간, 장소에 무관하게 사용자의 건강을 관리해준다. 이를 위해 이기종 의료 장비간 정보공유와 호환성 보장을 위한 의료 정보 표준화는 필수다. 적합한 표준이란 다양한 타입의 정보와 장비의 특성을 포괄하며 적용이 쉬운 표준이다. HL7은 대표적 예이지만 비텍스트 기반 신호, 특히 파형 정보를 다루는 데부족한 점이 있다. 이 점을 보완하기 위해 JAHIS에서 의료 파형에 적합한 표준(MFER)을 제시하였다. MFER은 파형정보 측면에서 HL7이 가지지 못한 장점을 가지고 있으나 실시간 적용에는 적합하지 않다. U-healthcare system의 본래 목적상 실시간 응용에 대한 요구는 크다. 따라서 앞의 표준들의 장점은 유지하고 단점은 보완할 수 있는 표준이 필요하다. 본 논문에서는 첫째, U-healthcare system을 위한 의료 정보 표준중 대표적인 HL7, MFER에 대한 리뷰와 두 표준관련 연구 동향을 소개한다. 둘째, 앞의 표준을 수정하여 실시간 응용에도 접목할 수 있는 scheme(TS-MFER with HL7)을 제안하고 실제 적용 결과를 제시한다.
