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.

Recently, many of hospitals have hurried to computerize the resulting data from medical devices, in order to introduce Electric Medical Record(EMR). In terms of the linkage between medical devices and hospital information systems, however, many difficulties have arisen due to some reasons such as the variety of prescription input, the format difference of the resulting data sheet, and the interface difference between medical devices from different companies. To solve these problems, many researches on standardization of the resulting data of medical devices have been performed. In this study, the linkage between hospital information systems and resulting datum in Electrocardiogram(ECG) generating biosignal waveform was tested by applying Medical waveform Format Encoding Rules(MFER) Version 1.02, which has more advantages than existing global standard. MFER viewer, in addition, was made to display the resulting data on a screen. The MFER viewer was tested and compared to the existing Scalable Vector Graphics (SVG) Viewer. The results showed that this method is more effective in the interface the data storage and application, because of simplicity and easiness in data applications. And the results show that the MFER is convenience and effective for physician. It is considered that the role of MFER as the interface in biosignal waveform including Electrocardiogram medical devices would expand in the near future.

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.

최근 의료기기의 디지털화와 더불어 IT 기술의 융복합화에 따라 다양한 의료기기들이 등장하고 있다. 특히 의료분야에서 발생하는 파형을 디지털화 시킴으로써 컴퓨터 등과 같은 기기를 통하여 정확한 분석이 가능하며 장기적으로 보관이 가능하다. 또한 디지털 파형의 포맷 규격을 정형화 함으로써 HL7 이나 DICOM 과 같이 상호 호환성, 정보교환이 가능하다. 특히 ECG, EEG 등과 같은 파형들은 개개인의 건강정보를 분석하기 위해 필수적인 요소이다. 본 논문에서는 ISO/TS 11073-92001 규격으로 제정된 MFER (Medical waveform description Format Encoding Rules)를 기반으로 바이오 레이더 신호를 저장할 수 있는 모듈에 관하여 기술한다.

This study has a purpose of development of mobile health monitoring system for measuring, saving and transmitting health signals by standardizing and encoding methods under the mobile environment. The system consists of a module for measuring the health signals with Bluetooth function, encoding equipment for encoding the measured health signals by a standardized encoding method so as to maintain mutual compatibility between devices, and a mobile system for saving and transmitting the encoding health signals. The proposed system was realized under the mobilet environment and has showed to be able to make good use.

Typically, the vital signs that are representing the state of human body, are the body temperature, sphygmus, respiration and blood pressure. The body temperature is the result of metabolic regulation and human steady-state body temperature is maintained from 35.9 to $37.4^{\circ}C$ by heat regulatory center. The body temperature is indicative of infection and especially it should be monitored to requiring intensive care patients or after surgical patients. But, measuring of body temperature to a heavy workload on nursing staff has been recognized. And, the health service of nurse is limited by simple tasks such as the measurement and record of vital sign. In this paper, the body temperature monitoring telemetry system was proposed to prove the recoding and transmission of body temperature patch system according the standard(ISO TS11073-92001). We proposed the transmission protocol to suit the MFER(medical waveform format encoding rules). The telemetry patch system was implemented and it was verified by experiments.
