位元世界 1/2 l l 一個位元 (bit)可以代表一個事實的兩個狀態，例如，電燈的 “ 開 ”或 “關 ”、性別的”男 ”或 ”女 ”（只有這樣子嗎？）。 兩個位元可四種狀態，有下列組合： 00、 10、 01、 11。方向， 00代 表往前、01代表往後， 10代表往右， 11代表往左。
位元世界 2/2 l l l n個字元就具備有 2 n個狀態。 N=8時，稱之為位元組 (Byte)。共 256個狀態。 這 0~255個數字分別給予指定的文數字或符號，稱 之為 ASCII碼。American Standard Code for Information Interchange，美國訊息交換標準代碼。 Char Dec Oct Hex ! 33 0041 0 x 21 + 43 0053 0 x 2 b 0 48 0060 0 x 30 1 49 0061 0 x 31 A 65 0101 0 x 41 B 66 0102 0 x 42 a 97 0141 0 x 61 b 98 0142 0 x 62 交換標準始焉！！
資訊的層級 l 事實 fact – – l l 所關心的某一事件。描述方向、性別。 此事件可以攜帶的資料。 00代表往前、 01代表往後， 10代表 往右，11代表往左。 資料 data 資訊 information – l 知識 knowledge – l 資料經過有目的處理。某人從原點 (0, 0)出發，收集 {00, 10, 00}資料，得知離開原點至座標 (1, 3) 學習所得，前往該點有哪些路徑。 {00, 10, 00}也可到座標 (1, 3)。資訊重現。 智慧 wisdom – 可以產生新的路徑 資訊創新 但！資料 (訊 )交換在哪一層級 從人的角度 從電腦的角度

資訊涵義 l 句法方面 (Syntactic Aspect) – l 語意方面 – l 描述語法、儲存或訊息傳輸的文法或語法有關。 (Semantic Aspect) 資訊所呈現的意義 實用方面 (Pragmatic Aspect) – 意圖或將被達成的目標 台灣大勝日本 V. S. 台灣大敗日本 但！電腦傳遞的資訊是？

What’s HL 7 l l Health Level Seven is one of several American National Standards Institute (ANSI) -accredited Standards Developing Organizations (SDOs) operating in the healthcare arena. Members of Health Level Seven are known collectively as the Working Group, which is organized into technical committees and special interest groups. – – The technical committees are directly responsible for the content of the Standards. Special interest groups serve as a test bed for exploring new areas that may need coverage in HL 7’s published standards. More information

HL 7's Mission l l HL 7 is an international community of healthcare subject matter experts and information scientists collaborating to create standards for the exchange, create standards exchange management and integration of electronic management integration electronic healthcare information. HL 7 promotes the use of such standards within and among healthcare organizations to increase the effectiveness and efficiency of healthcare delivery for the benefit of all.
What Does the Name HL 7 Mean l l l "Level Seven" refers to the highest level of the International Organization for Standardization (ISO) communications ISO model for Open Systems Interconnection (OSI) - the OSI application level. The application level addresses definition of the data to be definition exchanged, the timing of the interchange, and the communication of certain errors to the application. The seventh level supports such functions as security supports checks, participant identification, availability checks, exchange mechanism negotiations and, most importantly, data exchange structuring.

Ballots l l The end product of a ballot process is a document. The document could stand on its own. However, most balloted documents are a part of a published Standards Document (e. g. , HL 7 2. 6, HL 7 3. 0, etc. )
Ballots l Documents can be: – – Reference：Content is harmonized during HL 7 meetings or Reference approved by the HL 7 Board. It is not subject to ballot acceptance. Informative：Content is balloted by the general membership. Informative However, it is not considered to be a structural part of the Standard but only supporting information. Normative：Content is balloted by the general membership and is Normative considered a structural component of the HL 7 Standard. Negative ballots must be resolved. Draft Standards for Trial Use (DSTU)：Content is balloted by Use the general membership as the draft of a future standard which will, following a pre-specified period of evaluation and comment (usually 2 years), be expeditiously incorporated into normative standard.
