  • The purpose of this study is to analyze quantitatively the use of statistics, especially inferential statistics, in library and information science. Thus this study compared the use of statistics in library and information science with it in social work and education. The results of this study are as follows: First, the result is that, when the proportions of articles in each of the three categories of use are compared, library and information science is deficient in the use of inferential statistics and unusually productive of articles in 'No Statistics' category and 'Descriptive Statistics Only' category. Second, ANOVA showed no significant difference in the means for number of articles with no statistics and for articles with descriptive statistics only, but did show a statistically significant difference for the means for number of articles with inferential statistics. That is, the use of inferential statistics in library and information science was very less than the other subject areas. Third, a comparison of the numbers of various inferential statistics for each of the three subject areas indicated that the differences were not significant. This fact means that the quality of inferential statistics used in library and information science was similar to the other subjects.

  • This paper reviewed the temporal changes in the public opinions on nuclear energy in Korea with a big data analysis of nuclear energy-related articles and their comments posted on the portal site NAVER. All articles that included at least one of "nuclear energy," "nuclear power plant (NPP)," "nuclear power phase-out," or "anti-nuclear" in their titles or main text were extracted from those posted on NAVER in January 2010-December 2019. First, we performed annual word frequency analysis to identify what words had appeared most frequently in the articles. For that period, the most frequent words were "NPP," "nuclear energy," and "energy." In addition, "safety" has remained in the upper ranks since the Fukushima NPP accident. Then, we performed sentiment analysis of the pre-processed articles. The sentiment analysis showed that positive-tone articles have been reported more frequently than negativetone over the entire analysis period. Last, we performed sentiment analysis of the comments on the articles to examine the public's intention regarding nuclear issues. The analysis showed that the number of negative comments to articles each month-irrespective of positive or negative tone-was always larger than that of positive comments over the entire analysis period.

  • "Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows; 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview, physical measurement, observation were used in 22.8%, 8.2%, 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

  • 본 논문은 정보과학 분야를 중심으로 학술대회 논문에서 참고자료를 인용하는 패턴을 분석하고 피인용된 참고자료의 다양한 특성이 추후 그 자료를 참고한 학술대회 논문의 인용수에 어떤 영향을 끼치는지 분석하였다. 참고자료의 인용패턴에 관한 계량서지학 연구는 학술지 논문을 중심으로 활발히 이루어졌다. 하지만 점점 커지는 중요성에도 학술대회 논문을 대상으로 한 계량서지학 연구는 그 자체가 아직 초기 단계이다. 특히, 학술대회 논문에서 참고자료를 인용한 패턴이나 학술대회 논문의 인용수와 관련이 깊은 피인용 자료의 특성들을 조사하는 연구는 미비하다. 따라서 본 연구는 1,900여편의 정보과학 관련 학술대회 논문을 표본논문으로 삼고 그 표본 논문에서 참고자료가 어떻게 인용되었는지 패턴을 살펴보았다. 또, 참고자료의 다양한 특성들(참고자료의 유형 및 개수, 피인용 당시 참고자료의 인용수, 피인용 당시 참고자료의 나이, 저자의 자기인용 비율)이 표본논문과 추후 얻게 될 인용수와 어떤 연관이 있는지 조사하였다. 그 결과, 피인용 참고자료의 53%가 학술대회 논문이었고, 29%가 학술지 논문이었다. 특히, 참고자료의 14%가 학술지 논문이나 단행본이 아닌 비전형적인 참고자료의 유형이었다. 그리고 참고자료의 60% 이상이 5년 이내에 발표된 자료이고, 최신자료일수록 학술대회 논문, 웹 페이지, 기타자료의 비중이 높았다. 참고자료 중 자기 인용비율은 1.7%로 미비했다. 마지막으로 표본논문의 인용수에 유의미한 영향을 끼치는 참고자료의 특성은 참고자료로 쓰인 학술대회 논문의 수, 기타 자료의 수, 그리고 참고자료의 평균나이였다. 즉, 학술대회 논문과 기타자료를 참고자료로 많이 사용하고 최신의 자료를 많이 참조한 표본논문일수록 많이 인용되었다.

  • Objectives: Citation analysis provides a unique insight into how scientific interests and research trends have changed over time. The aim of this study was to report on the 50 top-cited papers in dental stem cell research using the Science Citation Index Expanded provided by the Web of Science database to determine the academic importance of each contribution. Materials and Methods: After the screening, article title and type, total citations and citations per year, publication journal, publication year, first and senior authors, country of origin, institution, and university of reprint author were documented for the 50 top-cited articles in dental stem cell research. Keyword analysis was performed to determine which keywords were most/least popular. Results: Top 50-cited articles were cited between 179 to 2,275 times. The majority of papers were published in 2008 and originated from the United States with the highest contribution from the National Institute of Dental & Craniofacial Research. Journal of Dental Research published the highest number of top-cited articles, followed by Stem Cells and Journal of Endodontics. The greatest number of articles was published by two individual authors, Shi and Gronthos. Among 197 unique keywords, dental pulp stem cells and mesenchymal stem cells were the most frequently used. Thirty-eight of the 50 most cited articles were original articles, and 37 of them were in the field of basic science. Conclusions: Basic science studies in dental stem cell research published in high impact factor journals had the highest citation rates.

  • Objectives : Our primary objective lies in understanding the current landscape of translational research on acupuncture, moxibustion and pharmacopuncture. Methods : We searched our own selection of keywords of acupuncture, moxibustion and pharmacopuncture and translational research from three overseas databases (Pubmed, Scopus, Medicine) and four domestic databases (DBpia, KISS, Riss4u, Korea Med). Results : We have chosen 41 articles in total-40 articles on acupunture, 6 article on moxibustion(5 articles were duplicated in use in each category). Origin-wise, 48.8 %/24.8 %/17.0 % of our articles pool came from USA/China/Korea, respectively. UK, Austria, Thailand and Italy contributed the rest of our article pool. For those articles written in USA and China, review articles were the most common type. For the US articles, all 10 review articles were non-systematic reviews, while, for China's contribution, one out of 4 review articles were systematic review. Type-wise, our research pool's breakdown is as follows ; 17 review articles, 11 experimental research, 2 randomized controlled trials(RCT), 1 clinical trial, 4 conference reports, 1 letter, 1 study protocol and 4 uncategorized. Topic-wise, brain-neurology was most frequently referred with 8 articles, followed by parkinson's disease (3 articles) and epilepsy (2 articles). Conclusion : 1. In terms of research submission articles, Korea appears to be lacking translational research on acupuncture, moxibustion and pharmacopuncture, compared to USA and China, in our view. 2. Unlike the cases of USA and China, most of Korean translational research is limited to doing a T1 level of translational research. In order to bring bench-to-bedside to light. we believe, there should be more studies, and thereby a certain level of activation, to the T2 level of translational research in Korea. 3. Further, in our view there should be more efforts to improve article quality at the T1 level of translational research, which eventually becomes the fundamentals of the next level of research (i.e. T2 research), as well as to increase the number of research submissions, going forward.

  • Background: This study used bibliometric analysis of articles published about the topic of regional anesthesia from 1980-2019 with the aim of determining which countries, organizations, and authors were effective, engaged in international cooperation, and had the most cited articles and journals. Methods: All articles published from 1980-2019 included in the Web of Science database and found using the keywords regional anesthesia/anaesthesia, spinal anesthesia/anaesthesia, epidural anesthesia/anaesthesia, neuraxial anesthesia/anaesthesia, combined spinal-epidural, and peripheral nerve block in the title section had bibliometric analysis performed. Correlations between the number of publications from a country with gross domestic product (GDP), gross domestic product (at purchasing power parity) per capita (GDP PPP), and human development index (HDI) values were investigated with the Spearman correlation coefficient. The number of articles that will be published in the future was estimated with linear regression analysis. Results: Literature screening found 11,156 publications. Of these publications, 6,452 were articles. The top 4 countries producing articles were United States of America (n = 1,583), Germany (585), United Kingdom (510), and Turkey (386). There was a significant positive correlation found between the GDP, GDP PPP, and HDI markers for global countries with publication productivity (r = 0.644, P < 0.001; r = 0.623, P < 0.001, r = 0.542, P < 0.001). The most productive organizations were Harvard University and the University of Toronto. Conclusions: This comprehensive study presenting a holistic summary and evaluation of 6,452 articles about this topic may direct anesthesiologists, doctors, academics, and students interested in this topic.

Materials and Methods: Published articles related to fractured instruments were screened from online databases, such as Web of Science, Scopus, PubMed, and ScienceDirect, and highly cited papers, with at least 50 citations since publication, were identified. The most-cited articles were selected and analysed with regard to publication title, authorship, the journal of publication, year, institution, country of origin, article type, and number of citations. Results: The top 10 most-cited articles were from various journals. Most were published in the Journal of Endodontics, followed by the International Endodontic Journal, and Dental Traumatology. The leading countries were Australia, Israel, Switzerland, the USA, and Germany, and the leading institution was the University of Melbourne. The majority of articles among the top 10 articles were clinical research studies (n = 8), followed by a basic research article and a non-systematic review article. Conclusions: This bibliometric analysis revealed interesting information about scientific progress in endodontics regarding fractured instruments. Overall, clinical research studies and basic research articles published in high-impact endodontic journals had the highest citation rates.
