Abstract

On the ICT healing platform designed to issue early disease alerts, TOS connected between the provider of personal health-related data and the service provider and relayed personalized health data. In the previous study, TOS proposed how to monitor the retrieval and management of document/measurement resources by taking mobile devices into account. Recently the healthcare field, however, defined the standard items needed for communication and data exchanges with a mobile device through HL7 FHIR. This study designed a data grid model between TOS and FHIR to provide personal health resources relayed through TOS in FHIR bundle search sets. The proposed design was organized as follows: first, it stated similarities between the method of TOS resource request and that of FHIR observation request. Then, it designed an eventbus module to process a retrieval request for FHIR service based on the imdb and cluster technologies. The proposed design can be used to expand the old service terminals of ICT healing platform to mobile health devices capable of using FHIR resources.

질환 조기경보를 목표로 하는 ICT 힐링플랫폼에서 TOS는 개인 건강관련 데이터 공급자(provider)와 서비스 공급자 사이를 연결하여 개인화된 건강데이터를 중계한다. 이전 연구인 TOS에서는 모바일 기기를 고려하여 문서/측정 값 등의 자원에 대한 조회(retrieval) 및 관제 모니터링 방법이 제안되었다. 그러나 최근 헬스케어 분야에서, 모바일 기기를 이용한 통신 및 데이터 교환에 필요한 표준 항목들이 HL7 FHIR을 통해 정의되었다. 본 논문에서는 TOS를 통해 중계된 개인건강 자원을 FHIR bundle searchset으로 제공하기 위해서, TOS와 FHIR간의 데이터 그리드 모델을 설계하도록 한다. 제안 설계의 구성은 다음과 같다. 우선 TOS 자원 요청 방법과 FHIR observation 요청간의 유사점을 기술한다. 다음으로, IMDG 및 클러스터 기술을 기반으로 FHIR 서비스의 조회 요청을 처리하는 event-bus 모듈을 설계한다. 제안된 설계는 기존의 ICT 힐링플랫폼의 서비스 단말을 FHIR 리소스 활용이 가능한 모바일 헬스 기기로 확장하는데 활용할 수 있다.
