Management of biosignal data in mobile devices causes many problems in real-time transmission of large volume of multimedia data or storage devices. Therefore, this research paper intends to suggest an m-Health system, a clinical data processing system using mobile in order to provide quick medical service. This system deployed health system on IP network, compounded outputs from many bio sensing in remote sites and performed integrated data processing electronically on various bio sensors. The m-health system measures and monitors various biosignals and sends them to data servers of remote hospitals. It is an Android-based mobile application which patients and their family and medical staff can use anywhere anytime. Medical staff access patient data from hospital data servers and provide feedback on medical diagnosis and prescription to patients or users. Video stream for patient monitoring uses a scalable transcoding technique to decides data size appropriate for network traffic and sends video stream, remarkably reducing loads of mobile systems and networks.

We propose a specific ubiquitous sensor network (USN) architecture as a promising candidate of the future telemedicine model which offers the patient's mobility and more cost-efficient medical care system. This new USN architecture is a kind of cell-based secure sensor network supporting encrypted multi-casting communications and it has a hybrid routing protocol by adapting flat routing to hierarchical routing. For the patient's privacy and the protection of patient's vital information from eavesdropping, we adopt a lightweight PKI-based secure communication protocol with some formal presentation on its core procedure.

최근 IT기술의 발달과 의료 서비스의 증가로 웨어러블 헬스케어에 대한 관심이 높아지고 있다. 기존 원칙 진료 시스템에서는 의사와 환자의 직접적인 대면 없이 진료데이터만으로 환자를 판단함으로 인하여 의료서비스의 질이 저하되는 문제가 있었다. 또한 원격진료만으로는 사용자의 증상을 정확하게 전달 할 수 가 없기 때문에 원격진료에 대한 사용자의 만족도가 낮았다. 이를 위해 본 논문에서는 VoIP 환경에서 화상진료를 지원하는 SIP 기반 스마트폰 헬스케어 시스템을 제안한다.

환자의 생체신호 측정 및 관찰, 영상 위생 등을 포함하는 직접간호는 간호사들의 총 간호활동 시간 중 내과는 48%, 외과는 40% 로 간호사들의 업무 부담이 되고 있다. 또한 의료기관에서 사용되는 의료기기들은 여러 회사에서 구매하여 사용되기 때문에 각 회사마다 상이한 프로토콜을 가지고 있어 하나의 시스템으로 생체신호를 모으기가 쉽지 않다. 따라서 여러 장비에서 생체신호를 실시간으로 취득하여 통합 관리할 수 있는 시스템 개발을 통해 간호사의 직접간호 업무량을 줄여 간호사의 근무환경 개선뿐만 아니라 중증환자의 경우 환자 생체신호에 대한 실시간 원격감시가 가능하고 환자에게서 발생된 모든 생체신호가 데이터베이스 시스템으로 기록관리 됨으로 인해 환자의 생체 신호에 대한 이력 추적관리가 가능함으로써, 양질의 의료 서비스가 가능한 환자케어시스템을 개발하고자 한다.

본 논문은 통신 기술과 의료 센서 기술을 접목하여 일상생활에서 병원을 찾아가지 않고도 환자가 심전도, 호흡, 혈압 등을 측정 관리 할 수 있도록 한 헬스케어 시스템을 소개한다. 본 시스템을 통하여 환자 몸의 센서 데이터와 병원안의 시스템 사이에 체계적이 컴퓨팅 환경을 구축 할 수 있고, 더불어 환자가 자신의 상태의 효율적으로 관리할 수 있을 뿐 아니라 원격지의 의료진들이 환자의 상태를 모니터링 하고 응급상황 발생 시 그에 알맞은 최적의 의료 서비스의 제공이 가능해진다. 더불어, 웹을 통하여 진찰 및 치료를 제공 할 수 있도록 하여 인터넷이 가능한 곳이면 언제 어디서나 최적의 의료 서비스를 제공하고, 받을 수 있도록 하였다.

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.

In this paper, we deseribe a Medical Image Information System. Our system stores and manages 5 dimensional medical image data and provides the 3 dimensional medical data via the Internet. The Internet standard VR format. VRML(Virtual Reality Modeling Language) is used to represent the 3I) medical image data. The 3D images are reconstructed from medical image data which are enerated by medical imaging systems such ans CT(Computerized Tomography). MRI(Magnetic Resonance Imaging). PET(Positron Emission Tomograph), SPECT(Single Photon Emission Compated Tomography). We implemented the medical image information system shich rses a surface-based rendering method for the econstruction of 3D images from 2D medical image data. In order to reduce the size of image files to be transfered via the Internet. The system can reduce more than 50% for the triangles which represent the surfaces of the generated 3D medical images. When we compress the 3D image file, the size of the file can be redued more than 80%. The users can promptly retrieve 3D medical image data through the Internet and view the 3D medical images without a graphical acceleration card, because the images are represented in VRML. The image data are generated by various types of medical imaging systems such as CT, MRI, PET, and SPECT. Our system can display those different types of medical images in the 2D and the 3D formats. The patient information and the diagnostic information are also provided by the system. The system can be used to implement the "Tele medicaine" systems.

Electrocardiograph(ECC), one of the major vital signals, is widely used in the hospitals to check a heart disease patient. In tole-medicine information system, If the ECC signal could be acquired at the patient's home and sent to the physician via telecommunication line, the number of visit to the hospital and medical expenses can be reduced dramatically. The tole-medicine information system proposed by this paper is designed to acquire patient's ECC signal by portable ECC terminal at his or her home and to send it to the hospital server via internet. For the mobility of physicians, the patient's real-time data ran be viewed at any internet connected computer as well as server connected terminal.
