國立中正大學 資訊管理系醫療資訊管理研究所 吳帆所指導 李旭婷的 建立以 FHIR 格式交換之電子病歷系統及其視覺化呈現 (2021),提出Node js tutorial關鍵因素是什麼,來自於電子病歷、醫療資訊交換、快捷式健康照護互操作性資源。
而第二篇論文國立臺北科技大學 電子工程系 賴冠廷所指導 鍾岳璁的 使用蜂巢式網路之無人機即服務 (2021),提出因為有 軟體即服務、無人機、AMQP、WebRTC的重點而找出了 Node js tutorial的解答。
最後網站Documentation - Node.js則補充:This documentation describes the built-in modules provided by Node.js. It does not document modules provided by the community. Looking for API docs of previous ...
建立以 FHIR 格式交換之電子病歷系統及其視覺化呈現
為了解決Node js tutorial 的問題,作者李旭婷 這樣論述:
隨著科技的進步,病歷逐漸以資訊化的方式進行保存,可以隨時在不同醫療機構間傳遞病歷,目前國內仍以 CDA R2 作為醫療資訊交換標準,不統一的格式導致需花費更多的時間成本來進行資料轉換,且可能轉換不完整導致醫療資訊誤解。快捷式健康照護互操作性資源(Fast Healthcare Interoperability Resources [FHIR])於 2011 年由 HL7 組織提出,提供所有健康照護參與者一套共享資訊的統一標準規範。FHIR 目前已被眾多的組織所實施,截至 2019 年,美國有百分之八十四的醫療機構使用 FHIR 技術。本研究使用 FHIR 作為醫療資訊交換標準,模擬國內目前電
子病歷交換狀況,保持醫療資料完整性及正確性,提高醫療品質,並使用交換的醫療資訊建立動態儀表板幫助醫療人員進行醫療決策,最後透過 Apache Jmeter 進行系統效能評估,評估系統響應時間在請求數目增加的情況下,響應時間是否保持在可接受的時間範圍內,以利後續醫院資訊基礎設施的部署。
使用蜂巢式網路之無人機即服務
為了解決Node js tutorial 的問題,作者鍾岳璁 這樣論述:
無人機發展至今已是相當成熟的產業,因它的機動性高且可控制的成本相對較 低,若有運送物資、農事庶務、高風險場域探勘及醫療急難救助等類型的團體或私人 機構,都會考慮導入無人機來進行任務。而這些需求也誕生出多家針對無人機產業所 提供服務的公司,但它的缺點在於必須使用各家公司客製化的機型和軟體且均無法互 相通用,使用上彈性因此被大幅限制。因此本論文提出支援開源無人機 (Ardupilot) 系 統的雲端無人機服務,背後的設計理念是透過 AMQP 訊息訂閱模式以實現無人機和平 台之間的通訊,制定驗證身份和綁定無人機序號以實現多人平台控制,並整合 WebRTC 媒體串流技術來達成無人機即時景象觀測以及使
用 TensorFlow 加入物件辨識 的功能。在使用上,無人機端連接手機並開啟控制 APP,登入雲端平台後即可開始使 用本服務,目前主要提供的功能有即時互動式地圖控制、全程操作錄影、飛行軌跡紀 錄及多台無人機飛行監控。在未來,可望此服務可以幫助到有無人機飛行任務需求的 公共組織及企業。
