Access Project Book

為了解決SQL query的問題，作者Korol, Julitta 這樣論述：

This is a project book that guides you through the process of building a traditional Access desktop database that uses one Access database as the front-end (queries, reports, and forms) and another Access database to contain the tables and data. By separating the data from the rest of the database,

the Access database can be easily shared by multiple users over a network. When you build a database correctly at the outset, later this database can be migrated to another system with fewer issues and fewer objects that need to be redone. FEATURES-Understand the concepts of normalization-Build tabl

es and links to other data sources and understand table relationships-Connect and work with data stored in other formats (d104, Word, Excel, Outlook, and PowerPoint)-Retrieve data with DAO, ADO, and DLookup statements-Learn how to process text files for import and export-Create expressions, queries,

and SQL statements-Build bound and unbound forms and reports and write code to preview and print-Incorporate macros in your database-Work with attachments and image files-Learn how to display and query your Access data in the Internet browser-Secure your database for multi-user access-Compact your

database to prevent corruption resulting in data loss

醫療物聯網產業技術發展與未來展望之研究

為了解決SQL query的問題，作者李宜杰 這樣論述：

本文藉由研究文獻、產業資料及技術報告的內容，進行分析醫療物聯網的產業及技術現況，並進一步探討在全球新冠肺炎病毒疫情肆虐下，醫療物聯網扮演降低疫情衝擊之功能及角色。使用醫療物聯網作為健康監視系統，可以通過使用可穿戴健康監視設備、無線人體局域網、人工智慧和基於雲端遠程健康測試來提供即時監視。所已利用醫療物聯網功能組件（例如數據收集，存儲，傳輸和分析）來控制傳染病傳播的預警系統會很有幫助。本研究除了說明醫療物聯網的結構、生態系統、應用程式及穿戴裝置外，也介紹認知醫療物聯網及人本角度的醫療物聯網，並特別於第三章研究方法於實施，說明了「降低疫情衝擊的醫療物聯網結構」、「醫療物聯網中的人工智慧和大數據技

術」、「醫療物聯網的安全機制」、「各國（台灣、韓國、德國）因應新冠肺炎病毒上的醫療物聯網應用和技術」、「應用醫療物聯網降低新冠肺炎病毒疫情衝擊」。最後本研究說明了醫療物聯網未來的挑戰為「安全機制」、「安全有效的演算法」、「能源效率」、「交互操作、標準化及規格」、「隱私」及「信任」等潛在問題，以及對產業及後續研究提出建議。

利用雲端建構某國中學生理化科評量成績資訊系統

為了解決SQL query的問題，作者柯傑騰 這樣論述：

十二年國民基本教育自然科學領域課程綱要正式於108年實施，新課綱理化屬於自然科學領域，提倡素養導向的學習，所有的學習源自於生活，有別於以往填鴨式教學，強調結合實際生活情境，靈活運用。美國教育學者Bloom提到的教育目標中，將認知領域分為六個層次：知識(Knowledge)、理解(Compre- hension) 應用(Application)、分析. (Analysis) 綜合(Synthesis) 評鑑(Evaluation)。在高中超額比序中佔極為重要的教育會考，改變命題方向，減少記憶、背誦等「知識」的比例，大幅增加素養導向的試題。但學生彼此的生活經驗依家庭背景差異如父母職業、家境狀況…

等變因，影響到學生在高層次應用、分析的學習所落差的因素。本研究透過資料庫系統運算及雲端共用技術，利用學生理化平常考單元內容的成績、考試概念與學生家庭背景的相關資訊來進行探討與分析。此系統可以讓教師能及時查詢學生理化平常考單元內容的成績分布，同時針對學生家庭背景及平常考成績作交叉分析，藉此調整教學方向。此外，藉由雲端平台，家長能透過智慧型手機查詢學生平常考成績彙整資訊，可以更及時的了解學生目前的學習狀況。本研究依據理化科成績資訊管理系統內容需求，包括考試概念、考試題型、家庭完整性、父親教育、母親教育、族群、經濟狀況、性別、學生、單元名稱、考試作業主檔及明細檔等彙整。研究結果發現，比起傳統的紙本成

績單，此成績資訊系統能夠擁有更好的效果。其應用可推廣到校務系統上，以方便於老師、家長立即查詢相關資訊，並了解學生學習情況，並為學校在對學生做成績資訊查詢管理上帶來更方便的成效。
