We present a methodology that automatically selects indexing algorithms for each heading in Medical Subject Headings (MeSH), National Library of Medicine's vocabulary for indexing MEDLINE. While manually comparing indexing methods is manageable with a limited number of MeSH headings, a large number of them make automation of this selection desirable. Results show that this process can be automated, based on previously indexed MEDLINE citations. We find that AdaBoostM1 is better suited to index a group of MeSH hedings named Check Tags, and helps improve the micro F-measure from 0.5385 to 0.7157, and the macro F-measure from 0.4123 to 0.5387 (both p < 0.01).

여러 색인들에 수록된 한국의학논문의 중복정도를 연구하여, 연구업적을 효율적으로 평가하기 위한 색인 선정방법을 제시하고자 하였다. EMBASE, MEDLINE, SCISEARCH에 수록된 1990년에서 1995년 사이의 한국의학논문 중에서, 외국 학술지에 게재된 한국의학논문의 건수와 연도별 증가추이를 조사 분석하였다. 1990년, 1992년, 1994년 3개년을 선정하여, 2개 이상 데이터베이스에서 중복 검색된 논문수, 특정 데이터베이스에서만 검색된 논문수, 그 논문들이 실린 학술지를 분석하였다. 의학연구업적을 평가할 때에, 한 개의 데이터베이스를 사용한다면 한국의학논문이 가장 많이 검색된 SCISEARCH를, 두 개의 데이터베이스를 활용한다면 EMBASE를 추가하는 것이 효율적인 데이터베이스 선정방법이라고 할 수 있다.

본 연구에서는 국내 의학학술논문의 저자가 선정한 주제용어(저자용어)와 MEDLINE 레코드의 MeSH 용어를 비교하여 국내 의학 학술논문 저자들이 얼마나 정확히 MeSH 용어를 사용하는지 일치도를 측정하였고, 사용방법상 어떠한 특징을 보이는지, 일치하지 않는 이유가 무엇인지 분석하였다. 1989년부터 1998년까지 Korean Journal of Parasitology에 발표된 415편의 논문에 사용된 1,826개의 저자용어 가운데 MEDLINE 레코드의 MeSH 용어와 일치한다고 볼 수 있는 용어는 35.5% (649개)로 한 논문에 평균 1.6개의 용어가 일치하였다. 이 가운데 완전히 일치하는 용어는 10.1%밖에 되지 않았다. 이와 같이 국내 의학학술논문 저자들은 MeSH 용어를 정확히 사용하기 위해 필수적인 체크태그 (Check tag), 계층구조 (Tree Structure), 부표목 사용 등 MeSH 용어 사용방법에 대한 지식이 부족한 것으로 나타났다.

최근 국제학술지에 등재되는 한국 의학논문이 증가하는 이유가 SCI 또는 MEDLINE 학술지를 선호하는 연구업적 평가정책과 관련이 있는지에 대한 관심이 국내학계에 존재하고 있다. 본 연구에서는 1980년대에 이어 1990년대에도 SCI 학술지나 MEDLINE 학술지에 많은 논문을 발표한 의학분야 중의 하나인 방사선학분야를 중심으로, 한국 의학자들이 1990년대에 발표한 논문들의 증가추세, 국제학술지와 국내학술지 논문 분포현황을 분석하여, 우리나라 의학 학술논문의 국제화 동향과 그 특성을 고찰하였다.

This study aimed to analyze the research trends of the abstract data of ergonomic studies registered in MEDLINE, a medical bibliographic database, using word embedding. Medical-related ergonomic studies mainly focus on work-related musculoskeletal disorders, and there are no studies on the analysis of words as data using natural language processing techniques, such as word embedding. In this study, the abstract data of ergonomic studies were extracted with a program written with selenium and BeutifulSoup modules using python. The word embedding of the abstract data was performed using the word2vec model, after which the data found in the abstract were vectorized. The vectorized data were visualized in two dimensions using t-Distributed Stochastic Neighbor Embedding (t-SNE). The word "ergonomics" and ten of the most frequently used words in the abstract were selected as keywords. The results revealed that the most frequently used words in the abstract of ergonomics studies include "use", "work", and "task". In addition, the t-SNE technique revealed that words, such as "workplace", "design", and "engineering," exhibited the highest relevance to ergonomics. The keywords observed in the abstract of ergonomic studies using t-SNE were classified into four groups. Ergonomics studies registered with MEDLINE have investigated the risk factors associated with workers performing an operation or task using tools, and in this study, ergonomics studies were identified by the relationship between keywords using word embedding. The results of this study will provide useful and diverse insights on future research direction on ergonomic studies.

Purpose: The purpose of this study is to examine acupuncture and moxibustion treatment suggested on the papers of urinary incontinence(UI) in medicine journals and to establish the future direction. Methods: The papers which were associated with acupuncture and HG published between 1992 and 2012 in Medline and Scopus were searched. Results: 14 studies met the condition. They were 3 randomized controlled trials(RCTs) and 5 clinical studies. 8 studies revealed that acupuncture and moxibustion have efficacies in UI. Conclusions: From the paper research, acupuncture and moxibustion treatment seem to be effective on UI. However, due to the lack sufficient research of UI, it would be necessary to fulfill further study about the period of acupuncture and moxibustion treatment on UI and the selection of acupoint through well-designed study and establish standard of evidence of them.

MediScore is an information retrieval system, which helps to search for the set of genes associated with a specific disease or the set of diseases associated with a specific gene. Despite recent improvement of natural language processing (NLP) and other text mining approaches to search for disease associated genes, many false positive results come out due to diversity of exceptional cases as well as ambiguities in gene names. In order to overcome the weak points of current text mining approaches, MediScore introduces statistical normalization based on binomial to normal distribution approximation which corrects inaccurate scores caused by common words not representing genes and interactive rescoring by the user to remove the false positive results. Interactive rescoring includes individual alias scoring for each gene to remove false gene synonyms, referring MEDLINE abstracts, and cross referencing between OMIM and other related information.

Objectives : Many cancer patients use therapies promoted as literal alternative and complementary medicine to conventional medical care. So the health provider has to guide it by appropriate clinical guideline. The purpose is to indicate the international research tool of korean medical oncology for related investigators and help to make the clinical guideline for korean oncology. Method : We reviewed complementary and alternative therapies for cancer and cancer-related symptoms by searching MEDLINE, and using the name and synonyms of the therapy. Publications on complementary medicine were identified by searching the Cochrane Library. Results and Conclusion : Most complementary and alternative medicine used by cancer patients have demonstrable, important benefits, including decreased symptoms and better quality of life. We have to standardize the scientific research protocol for korean oncology and build evidence based medicine in the future.

Objectives : The aim of this study was to develop search filters able to retrieve the South Korean scientific output and relating the fields of public health, preventive medicine, and physical education, activity, fitness, exercise and sport in MEDLINE between 2000 and 2007. Methods : The search filters were constructed and applied in MEDLINE accessed through PubMed according to the affiliation and subject. The language and place of publication were identified and the evaluation of the geographical filter performance was done. Results : The search format was successfully elaborated and applied, and the articles originated, published in Korea and/or abroad focusing on the fields of public health, preventive medicine, physical education, activity, fitness, exercise and sport, added to MEDLINE between 2000 and 2007 were retrieved. Publications in six languages originated in South Korea were detected. Conclusions : A geographic search filter determined the South Korean research output, and combined with additional filters focused on specific areas. The dynamics of the scientific output followed an increased evolution in all categories. Articles were written mainly in English/Korean. Further research is recommended on developing search strategies in order to retrieve precise and reliable information.
