1 S-2. 학술논문작성을위한선행연구조사와참고문헌검색 PubMed 연세대학교의학도서관 1

2 PubMed 미국국립의학도서관에서 1996 년에서비스시작된의학분야최고의 Database medicine, nursing, dentistry, veterinary medicine, health care systems, and preclinical sciences. 1947~65년 16,000건, 1966년이후 2,900만건이상의 Citation Adds citations Everyday E-Journal 원문과연결 - 471개정도의원문 Database와출판사에서약 8,764 여종원문제공 ( ) 2

3 MEDLINE 세계적인생의학 보건관련 Database 미국등 80 여개국가에서출판되는저널 ( 약 5,251 종 ) 수록된논문은 NLM 의통제어인 MeSH 로색인되어짐 (PubMed Indexed for MEDLINE) PubMed 에서가장큰부분을차지하고있음 3

4 PubMed 와 Medline PubMed 의구성 - MEDLINE 87% (2,500 만건의 citation) Started in the 1960s, it now provides more than 25 million references to biomedical and life sciences journal articles back to 1946 ftp://nlmpubs.nlm.nih.gov/online/journals/ljiweb.pdf - In Process - OLDMEDLINE Journal citations from Publisher - NCBI Bookshelf - Only PubMed 4

5 PubMed Central National Library Medicine( 미국국립의학도서관 ) 에서제공하는생의학및생명과학학술지의무료디지털아카이브 2000년 2월서비스시작 목적 : 1 NIH의기금지원으로생산된모든연구성과물에대한중앙리포지토리를구축함으로써생의학및생명과학핵심출판물을장기적으로보존 2 전세계과학자들이인터넷을통해의학분야의진보된연구출판물을쉽게접근가능 3 고품질의연구성과물을법적, 경제적, 기술적장벽없이이용가능하도록추진 HTML, PDF, PubReader 형태의원문과이미지제공 5

7 (1) 우리도서관 PubMed 우리도서관에서 E-J 을구독해서원문을바로볼수있는경우의료원내에서만이용가능 우리도서관에서구독하는 E-J 연결뿐만아니라다양한링크정보제공 Full text 연결 Link, Print J 소장정보, 원문복사신청, SCIE 등재된경우다른논문검색기능, JCR impact factor 값확인 7

8 (2) Searching Keywords 첫검색창에검색어를넣어서검색하는방법으로가장기본적인방법 Author Advanced 에서저자명검색을선택해서검색 Journal Advanced 에서학술지명을선택해서검색 주제어 MeSH(Medical Subject Heading) 검색주제어의상하개념을확인할수있고 subheading 을지정하여검색 8

9 1 Keywords 검색 1. AND, OR, NOT 검색 lung OR cancer: lung 이나 cancer 둘중하나만포함되어있으면검색 lung AND cancer : lung 과 cancer 가모두포함된논문검색 lung NOT cancer: lung 검색결과에서 cancer 가포함된논문은제외 2. Phrase 검색 단어구로검색하기위해서는 사이에구를입력 3. Nesting 검색 ( ) 가있으면우선검색 4. Truncation 절단검색을원할때는 * 를사용하여검색예 : child* (child, children, childhood 등 ) 9

10 검색식작성 동일한개념간연산 : OR 상이한개념간연산 : AND 민감도와특이도의균형을맞추는것이중요 민감도를높이기위한검색 : 제한을하지않고검색해서많은검색결과를얻기위한방법 특이도를높이기위한검색 : 제한을최대한으로해서정확한검색결과를얻기위한방법
