2 大綱 Ovid Medline介紹 PubMed介紹 兩者之差異 作業題目 上機操作

3 學習目標 認識Ovid Medline 認識PubMed 瞭解兩者之差異 熟悉兩者之操作

4 Medline Medline Produced by the U.S. National Library of Medicine, the MEDLINE database is widely recognized as the premier source for bibliographic and abstract coverage of biomedical literature. MEDLINE encompasses information from Index Medicus, Index to Dental Literature, and International Nursing Index, as well as other sources of coverage in the areas of allied health, biological and physical sciences, humanities and information science as they relate to medicine and health care, communication disorders, population biology, and reproductive biology.

6 Medline The Ovid MEDLINE database contains bibliographic citations and author abstracts from more than 5,200 biomedical journals published in the United States and in 70 other countries. The database contains well over 16 million citations dating back to the 1950. Although coverage is worldwide, most records are derived from English-language sources or have English abstracts. Abstracts are included for more than 75% of the records.

7 PubMed 簡介 90% are published in English.
Published by : U.S. National Library of Medicine's® (NLM) Time coverage: to the present Source : 5,200 worldwide journals; 23 million references to journal articles in life sciences Updates: 2,000-4,000 completed references are added each day 90% are published in English. Broad subject coverage 資料來源：美國國家醫學圖書館網站

8 PubMed簡介 PubMed provides access to bibliographic information which includes MEDLINE as well as: The out-of-scope citations (e.g., articles on plate tectonics or astrophysics) from certain MEDLINE journals, primarily general science and chemistry journals, for which the life sciences articles are indexed for MEDLINE. Citations that precede the date that a journal was selected for MEDLINE indexing. Some additional life science journals that submit full text to PubMedCentral and receive a qualitative review by NLM.

9 Related articles之功能 Each citation in PubMed has a link that will retrieve a pre-calculated set of PubMed citations that are closely related to the selected article. Click on Related Articles to the right of each citation to display the related set of articles. PubMed creates this set by comparing words from the title, abstract, and MeSH terms using a powerful word-weighted algorithm. Citations are displayed in rank order from most to least relevant, with the "linked from" citation displayed first.

10 Link Out之功能 LinkOut allows publishers, aggregators, libraries, biological databases, sequence centers, and other Web resources to display links to their sites on items from the Entrez databases. These links can take you to the provider's site to obtain the full-text of articles or related resources, e.g., consumer health information. There may be a charge to access the text or information. The current list of LinkOut providers is available.

24 上機練習 Locate articles published in Oncotarget by Yun Yen. （20%）
Locate article(s) about Zika virus [as the main topic] for baby girls in Spanish. (20%) I need to find some non-English articles entitled “… AIDS…HIV… ”（篇名中有此關鍵字出現的非英文文獻）(20%) I am looking for some information on the relationship between food and aging for people older than 80 years old published from (20%) 我要找中年男性中風後復健的相關文獻, 證據等級越高越好. (20%)

25 作業一 Locate the article published in Lancet by Dr. Chun-Chao Chang. (北醫附醫張醫師刊登在Lancet 與人合著的文章) Locate article(s) about flu [as the main topic] for children between 6-12 years old written in German. I need to find some non-English articles entitled “…SARS… infection… ”（篇名中有此兩個關鍵字出現的非英文文獻） I am looking for some information on the relationship between body weight and heart diseases for women older than 65 years old published from 2007. 我要找男性患乳癌之死亡率的文獻, 證據等級越高越好

26 作業二 請自選一個concept，分別在OVID Medline 和PubMed中進行自然語言和控制字彙的檢索,作業內容應包括：
封面(系級,姓名,學號, 檢索的題目說明) 分別列印出所有的檢索過程 [Prt Scr] Ovid Medline  1)自然語言, 2) 控制字彙　 PubMed 1)自然語言, 2) 控制字彙　 比較兩者之不同 Ovid Medline NL vs. CV (檢索結果，檢索過程，使用感想) PubMed NL vs. CV(檢索結果，檢索過程，使用感想) Ovid vs. PudMed （檢索結果，使用者介面，系統功能） 請用Ovid Medline1946- 做檢索，並以〔Alt〕+〔Print Screen〕將檢索策略與檢索結果剪貼於作業中[不是用in process喔!]
