臺灣博碩士論文加值系統

本論文的研究目的是希望能藉由寬頻網路與網際網路的發展，整合現行居家照護的特性，建構出一個多功能的遠距居家照護系統，提供一般病患、慢性病患、失能者家屬甚至肢障者使用。為了提供熟悉電腦與不熟悉電腦的族群使用，系統設計分為PC版及Non PC版兩種，以減少照護者使用本系統的門檻。
主要的設計目標是有效改善醫療院所病床被慢性病患長期使用的問題，同時提供慢性病患如同在院照護應有的品質以改善其家庭生活模式。期待以有限的照護人力，發揮最佳的照護效益，主要是著眼於交通時間所造成的時間耗費，因此若採遠距方式可免舟車辛苦。以及改善照護者需兼顧實際照護工作與學習照護技巧的困擾，採非同步上網學習，打破時空限制。並提供肢障者，一個照護與自我學習的環境，整合所建構的遠距居家看護系統，輔以肢障者專用的人機介面，達到自我學習又不失照護的原意。
為了達到上述目標，本論文以混合式光纖同軸網路為平台，進行視訊、聲音及生理信號的傳送。對於PC-Based而言，本論文探討以纜線數據機進行視訊、聲音及生理信號的傳送，以瀏覽器為界面進行遠距居家照護服務，並整合網際網路資源，使用者亦可上網學習相關衛教知識。就Non PC-Based系統的設計方法，採傳統有線電視播送方式傳送視訊及聲音，配合本文所設計的生理信號傳收電路(RF Modem)，整合成遠距居家照護系統。其中RF Modem的設計是將生理信號調變後插入到電視頻道的第二頻道(雙語頻道)，避免再佔用一個電視頻道。同樣地，若照護者擬學習衛教知識可收視當地有線電視台的節目。
有關肢障者的遠距照護模式，是採PC-Based系統配合人機界面裝置(頭動眼控滑鼠系統)，以頭部移動及眨眼模擬成一般電腦滑鼠界面，達成控制電腦游標的目的。
相關的系統設計及工程技術評估均已完成，期望未來系統使用時，能提供一個有效的居家照護機制，解決醫護人員或病患舟車勞頓之苦。

In this dissertation we propose a multifunctional home telecare system. Based on the Internet and broadband networks, this system integrates several health care functions and provides remote home health care services to general, chronic, and handicapped patients. The system has two versions, referred to as PC-based and non-PC based home telecare systems, the use of which depends on the user''s computer skills.
The goals of the home telecare system are to solve the problem of too many hospital beds being occupied by patients with chronic illnesses and to provide home service as good as in-hospital care. Cost-efficiency is an important issue in this system, which seeks to reduce the time spent transporting patients. In addition, some video demonstrations are provided by the system''s broadband network, simultaneously teaching nursing personnel relevant health care skills.
This system use a platform based on a hybrid fiber coaxial (HFC) CATV network in Taiwan, which was designed to make a home telecare service feasible. The system combines biomedical data with video and audio for communication between patient and health-care provider. In the PC-based version, commercial cable modems could be installed and used for biomedical data, video, and audio transmission. The user interface is a user-friendly browser that can support health education using Internet resources. The non-PC based version uses analog CATV to transmit video and audio signals via a National Television Standard Committee (NTSC) channel. This version provides an RF modem interface, which inserts biomedical signals into the HFC network. The RF modem puts digitized biomedical signals into the second audio program (SAP) sub-channel, which can be used for second-language audio in NTSC television broadcasts.
A human-machine interface was designed to allow quadriplegics to control the computer cursor. This system--an optical head-mouse--uses an optical head-pointer to shoot a laser beam to sensors built into the receiving panel. The computer cursor is controlled on the basis of signals received by the sensors. The click command is executed by blinking the eye. Mouse functions and a character entry simulator are provided for disabled individuals. This interface can be used to provide home telecare services in conjunction with a PC-based version that can be self-operated by the disabled.
The whole system has been implemented and tested. One future task is to assess the feasibility of this system in clinical applications. We hope to provide an efficient method for home telecare services that will ease the inconvenience of routine transportation of chronically ill and handicapped patients.
