Objectives: Advancements in nanotechnology have led to the widespread usage of nanoparticles in the endodontic field. This bibliometric study aimed to determine and analyze the top 100 most-cited articles about nanoparticles in endodontics from 2000 to 2022. Materials and Methods: A detailed electronic search was conducted on the "Clarivate Analytics Web of Science, All Databases" to receive the most-cited articles related to the topic. Articles were ranked in descending order based on their citation counts, and the first 100 were selected for bibliometric analysis. Parameters such as citation density, publication year, journal, country, institution, author, study design, study field, evidence level, and keywords were analyzed. Results: The top 100 most-cited articles received 4,698 citations (16-271) with 970.21 (1.91-181) citation density in total. Among decades, citations were significantly higher in 2011-2022 (p < 0.001). Journal of Endodontics had the largest number of publications. Canada and the University of Toronto made the highest contribution as country and institution, respectively. Anil Kishen was the 1 who participated in the largest number of articles. The majority of the articles were designed in vitro. The main study field was "antibacterial effect." Among keywords, "nanoparticles" followed by "Enterococcus faecalis" were used more frequently. Conclusions: Developments in nanotechnology had an impact on the increasing number of studies in recent years. This bibliometric study provides a comprehensive view of nanoparticle advances and trends using citation analysis.

Objectives: This study aimed to analyze the main features of the 25 most-cited articles in minimally invasive access cavities. Materials and Methods: An electronic search was conducted on the Clarivate Analytics' Web of Science 'All Databases' to identify the most-cited articles related to this topic. Citation counts were cross-matched with data from Elsevier's Scopus and Google Scholar. Information about authors, contributing institutions and countries, year and journal of publication, study design and topic, access cavity, and keywords were analyzed. Results: The top 25 most-cited articles received a total of 572 (Web of Science), 1,160 (Google Scholar) and 631 (Scopus) citations. It was observed a positive significant association between the number of citations and age of publication (r = 0.6907, p < 0.0001); however, there was no significant association regarding citation density and age of publication (r = -0.2631, p = 0.2038). The Journal of Endodontics made the highest contribution (n = 15, 60%). The United States had the largest number of publications (n = 7) followed by Brazil (n = 4), with the most contributions from the University of Tennessee and Grande Rio University (n = 3), respectively. The highest number of most-cited articles were ex vivo studies (n = 16), and 'fracture resistance' was the major topic studied (n = 10). Conclusions: This study revealed a growing interest for researchers in the field of minimally invasive access cavities. Future trends are focused on the expansion of collaborative networks and the conduction of laboratory studies on under-investigated parameters.

본 연구는 서울특별시 A구 산하 9개 도서관 이용자들의 대출 기록을 모두 조사하여 주제별 장서이용 행태를 분석하고 주제 분야 간 어떠한 연관성을 지니고 있는가를 알아보는데 그 목적이 있다. 이를 위하여 2006년 6월부터 2014년 6월까지 발생한 2,723,115건의 대출 기록을 수집하여 분석하였다. 한국십진분류(KDC)에 따라 총류(000)부터 역사(900)까지 10개 대분류와 총류(000)부터 전기(990)까지 100개 중분류로 나누어 주제별 대출빈도를 분석하였으며, 도서관 이용자들의 대출기록 기록을 중분류에 따른 상관계수에 근거한 군집분석을 통하여 주제별 연관성을 분석하였다.

This article shows an approach to the study of two fundamental aspects of the prepublication of scientific manuscripts in specialized repositories (arXiv). The first refers to the size of the interaction of "standard papers" in journals appearing in the Web of Science (WoS)-now Clarivate Analytics-and "non-standard papers" (manuscripts appearing in arXiv). Specifically, we analyze the citations found in the WoS to articles in arXiv. The second aspect is how publication in arXiv affects the citation count of authors. The question is whether or not prepublishing in arXiv benefits authors from the point of view of increasing their citations, or rather produces a dispersion, which would diminish the relevance of their publications in evaluation processes. Data have been collected from arXiv, the websites of the journals, Google Scholar, and WoS following a specific ad hoc procedure. The number of citations in journal articles published in WoS to preprints in arXiv is not large. We show that citation counts from regular papers and preprints using different sources (arXiv, the journal's website, WoS) give completely different results. This suggests a rather scattered picture of citations that could distort the citation count of a given article against the author's interest. However, the number of WoS references to arXiv preprints is small, minimizing this potential negative effect.

본 연구는 '미적 과학교육 연구'를 서지분석을 통해 그 동향을 파악한 후, 앞으로 이 분야의 연구에 대한 시사점을 제공하는 것을 목표로 한다. 이를 위해 Clarivate Analytics에서 제공하는 Web of Science 웹데이터베이스의 검색기능을 활용하여 미적 과학교육 연구 100편을 추출하였으며, 이를 R 프로그램의 Bibliometrix 패키지를 이용하여 상세 서지분석을 실시하였다. 분석 결과, 1993년부터 2022년까지 평균적으로 논문의 수가 증가하는 추세였으며, 관련 논문이 출판되는 학술지는 지역적으로 균등히 분포되어 있는 양상을 보였다. 키워드 분석, 상위 인용수를 가지고 있는 논문, 저자 협력 네트워크, 문헌 공동 인용 네트워크 등을 통해 살펴본 결과, 과학교육에서 미적 측면은 과학교육에서 예술을 통합하여 미적 경험을 유도하는 범주, 과학의 미적 측면에서 '형태의 미'와 '정서적 반응'을 활용한 범주로 구분 지을 수 있었다. 본 연구를 통해 도출한 시사점은 다음과 같다. 첫째, 미래 과학교육에서 강조하는 행위주체성과 능동적 학습을 실현하기 위해 미적 과학교육 연구가 활발히 수행되어야 한다. 둘째, 과학의 '형태의 미'를 과학교육에 좀 더 활용하여 과학교육에 대한 새로운 접근법을 개발할 필요가 있다. 셋째, 과학의 미적 측면은 교사, 예비교사, 학생의 과학의 본성에 대한 인식을 변화시킬 수 있다. 넷째, 과학의 미적 측면에 대한 교사, 학생, 예비교사 등을 대상으로 한 광범위한 인식조사를 통해 과학교육에서 미적 측면을 활용하는데 있어 시사점을 도출하여야 한다. 본 연구는 미적 과학교육 연구의 전체적인 분석 자료를 제공했다는 점에서 의미가 있다.
