In this paper, we designed efficient reception system using service robot based on the RFID(Radio Frequency Identification) and HL7(Health Level 7) Protocol. The proposed system offer a paramedic the medical information of the patient, and the patients can receive on a much simpler scale than previously through stable and quick information exchange by RFID and HL7. In addition, We considered environment of medical treatment and designed and implemented standard HL7 message structure. This system was implemented service robots to reception of medical treatment. Furthermore, we have plan to develop bio-sensor which can measure blood pressure, body temperature, etc and interface with robot system by HL7.

유비쿼터스 환경에 대한 기술적 발전에 따라 다양한 u-Health 서비스 시스템이 개발되어 시행되고 있다. u-Health 시스템은 서비스 인프라인 병원, 의료기관의 의료정보시스템 연동을 통한 의료정보활용이 불가피하다. 그러나 HL7 의료정보 표준안은 헬스케어 시스템에서 활용하는 의료정보에 대한 명세를 제시하지 못하고 있다. 즉 의료정보시스템으로부터 정보를 요청/제공 받기 위한 HL7 표준 메시지가 명시되어 있지 않다. 따라서 본 논문에서는 헬스케어 시스템에서 필요로 하는 병원 내 의료정보를 분석하고 적합한 HL7 표준 메시지 구조를 설계하였다.

In this paper, we designed the RFID(Radio Frequency Identification) Emergency Medical Information System(REMIS). This REMIS offers the emergency patient's medical information using RFID and HL7(Health Level 7) to an emergency medical technician. In emergency situation as like coma, if the communication, from the patient's current location to the hospital, is possible, REMIS offer the medical information of the patient through REMIS server to an emergency medical technician. In the state of communication blocked, REMIS can offer the patient identification and the emergency information through RFID tag, which the patient wear, to an emergency medical technician. When this system was designed, the protection of the patient's medical information and their privacy was considered, and the HL7 was used to be compatible with another medical systems. Therefore, in this paper, REMIS was designed that it is always possible to offer the emergency patient's information to an emergency medical technician regardless of any communication status and to improve the emergency rescue process, effectively.

Recently supply of Internet is bringing a important change in medical environments. The hospitals which had a different system is required the system that can efficiently share and exchange medical information. In order to transmission medical information between systems, the Health Level Seven(HL7) interface engine development that can convert medical data to HL7 messages is necessary. The HL7 is a standard protocol for data exchange in healthcare environments. In this paper, I implemented HL7 interface engine for Alzheimer's disease in elderly care facility. The interface engine is composed of the client system and the server system. The client system inputs user's medical care data for the aged, and builds them into HL7 message stream. HL7 messages in the client system transmitted over TCP/IP protocol to the server system. The server system parses and validates this messages stream to the segments and fields and then transmits acknowledgement to the client system. I implemented it using the Java and JavaCC. The study of interface engine implementation can be used meaningfully in electronic health record, telemedicine system, and medical information sharing among various healthcare institutions.

Hypertension is one of the major causes of death in the world as it is related with cardiovascular or cerebrovascular disease, so it is needed to provide continuos management for blood pressure. This study selected Health Level 7 Fast Health Interoperability Resources (HL7 FHIR) as a bio-signal data exchange service model that can provide constant blood pressure management in the rapidly growing mobile health care environment. The HL7 FHIR framework developed communicates with the IEEE 11073-10407 Personal Health Device (PHD) protocol through the bluetooth Health Device Profile (HDP) between the manager (smart phone) and the agent (hemomanometer) and acquires information about blood pressure. According to the test results, it performed its tasks successfully including hypertension patients' blood pressure monitoring, management on measured records, generation of document, or transmission of measured information. Because in the actual, clinical environment, it is possible to transmit measured information through the TCP/IP protocol, it will be needed to conduct constant research on it and vitalize it in the field of mobile health care afterwards.

The previous HL7 interface should be developed as a separate package or conversion module for each version to process HL7 messages from different versions. This study designed and developed an HL7 parser compatible among different versions based on the requirements of compatibility defined in HL7 V2.5. According to the structure of the parser, the inheritance concept in object-oriented programming was adopted so that the class object of the HL7 message from the lower version could be inherited to the class object of the upper version. Therefore, every version's HL7 messages could be processed using only the upper class' object regardless of the version. To evaluate the compatibility of the developed parser, 700 data sets about inpatients with rheumatoid arthritis were used. The 700 cases underwent the compatibility test successfully. In the near future, further research on the Inter-compatibility HL7 parser is planned.

Background: The purpose of this study is to measure the Korean health literacy level and to analyse its gaps according to the factors of socioeconomic and health status and health behaviors. Based on this, policy implications were reviewed to improve the understandability on health information and to reduce the gap among socioeconomic groups. Methods: HLS-EU-Q47, a tool developed by the European Health Literacy Project, was used to conduct a face-to-face interview survey on the health literacy for the samples from general population. Results: The public general health literacy (HL) index was 34.5 out of 50. HL is consisted of three sub-dimensions: healthcare (HC-HL), disease prevention (DP-HL), and health promotion (HP-HL). And a HL analysis found scores of 34.7 points for HC-HL, 35.4 points for DP-HL, and 33.3 points for HP-HL. The level of all HL was different according to socioeconomic characteristics and health behavior. Conclusion: Based on the results of this study, more research activities on health-related literacy need to be conducted, and monitoring system on the HL level needs to be developed and implemented. In addition, a program to improve HL levels needs to be developed in order to strengthen the basis for a more sustainable healthcare system as an agenda with national health policy priority.

Recent developments in IT have made real-time ECG monitoring possible, and this represents a promising application for the emerging HL7 standard for the exchange of clinical information. However, applying the HL7 standard directly to real-time ECG monitoring causes problems, because the partial duplication of data within an HL7 message increases the amount of data to be transmitted, and the time taken to process it. We reduce these overheads by Feature Scaling, by standardizing the range of independent variables or features of data, while nevertheless generating HL7-compliant messages. We also use a De-Duplication algorithm to eliminate the partial repetition of the OBX field in an HL7 ORU message. Our strategy shortens the time required to create messages by 51%, and reduces the size of messages by 1/8, compared to naive HL7 coding.

Medical environments incorporate complex and integrated data networks to transfer vast amounts of patient information, such as images, waveforms, and other digital data. To assure interoperability of images, waveforms and patient data, health level seven(HL7) was developed as an international standard to facilitate the communication and storage of medical data. We also adopted medical waveform description format encoding rule(MFER) standard for encoding waveform biosignal such as ECG, EEG and so on. And, the study converted a broad domain of clinical data on patients, including MFER, into a HL7 message, and saved them in a clinical database in hospital. According to results obtained in the test environment, it was possible to acquire the same HL7 message and biosignal data as ones acquired during transmission. Through this study, we might conclude that the proposed system can be a promising model for electronic medical record system in u-healthcare environment.

의료 정보의 표준 데이터 교환 환경을 구축하기 의해서 의료정보분야의 전송표준인 HL(Health Level)7[1]을 이용하는 방법이 있다. 방대한 HL7 V2.4 메시지를 의료 관련 어플리케이션이나 시스템에서 사용하고자 한다면, 메시지 처리만 전담하는 인터페이스 엔진이 필요하다. 이 논문에서는 인터페이스 엔진을 만들기 위해, HL7에서 정의한 메시지 구조를 바탕으로 HL7 V2.4 메시지를 모델링 하였고, 인터페이스 엔진의 세 가지 기능(Message Validation, Message Building, Message Transmission)을 제안한다.
