Abstract PDF: Purpose
This study compared the growth, distribution, and publisher profiles of Scopus-indexed journals in the Association of Southeast Asian Nations (ASEAN) and East Asia between 2015 and 2024, with the aim of contrasting regional publishing patterns.
Methods
Journal data from the SCImago Journal Rank (SJR) were analyzed for five ASEAN countries (Indonesia, Malaysia, Philippines, Singapore, and Thailand) and five East Asian countries (China, Hong Kong, Japan, Korea, and Taiwan). The analysis focused on quartile mobility, open access patterns, and publisher growth over the study period.
Results
Both regions exhibited growth in Scopus-indexed journals, although this growth followed distinct national trajectories. Within ASEAN, Indonesia recorded the most substantial increase, whereas China accounted for the largest expansion in East Asia. Although many newly indexed journals entered the lower quartiles, Indonesia emerged as ASEAN’s largest Q1 contributor by 2024, while China dominated Q1 growth in East Asia. Open access output increased at a faster rate in ASEAN than in East Asia. Publisher activity also diverged between regions: Indonesian university presses drove a large share of ASEAN’s growth, whereas major Chinese publishers accounted for a substantial proportion of journal expansion in East Asia.
Conclusion
Journal indexing growth across the five ASEAN and five East Asian countries examined reflects distinct institutional pathways, with differing national strategies shaping the development of indexed journals.

Abstract PDF Supplementary Material: Purpose
This study presents a bibliometric analysis of research articles authored by North Korean researchers and indexed in Scopus between 1976 and 2024. By incorporating recent data, it updates previous findings and examines how developments such as COVID-19 border closures have affected domestic research activity and international collaboration.
Methods
Data were collected on June 15, 2025, using refined Scopus search parameters that addressed earlier limitations and improved the identification of records lacking country information. After data cleaning, the final dataset comprised 1,344 domestic articles and 1,210 internationally co-authored articles. These were analyzed by publication volume and institutional affiliation.
Results
The study compares trends before and after 2020, distinguishing between domestic and international research. It evaluates North Korea’s internal research capacity based on the number of contributing domestic authors and explores interinstitutional collaboration within the country. Major international partners were identified by analyzing co-author affiliations, with emphasis on China’s leading role. Additionally, network analysis was conducted to identify key countries involved in international collaboration and to visualize the centrality of cooperative institutions.
Conclusion
The findings reveal a marked increase in domestic publications in recent years, suggesting a shift toward greater self-reliance in response to external constraints such as the COVID-19 pandemic and international sanctions. The results also indicate steady enhancement of North Korea’s internal research capacity. Despite global isolation, international collaboration has remained relatively stable, partially sustained by long-standing partnerships with Chinese institutions. Based on these trends, continued growth in domestic research output and international engagement is anticipated.

Abstract PDF: Purpose
We analyzed the bibliometric characteristics of articles authored by individuals affiliated with North Korean medical education institutions indexed in PubMed, using an expanded search strategy to update prior studies.
Methods
Our search revealed both a significantly larger number of publications and a greater capacity for substantive research with international impact than previously reported. We reviewed 331 records, selecting 79 for inclusion. For each publication, we collected data regarding the involvement of North Korean patients as primary research subjects, research methods employed, international partnerships, study topics, the impact factor of the publishing journal, and the number of cross-referencing citations.
Results
We identified 10 publications presenting primary data from North Korean patients, 3 of which involved prospective, randomized clinical trials. North Korean authors frequently collaborated with international partners—primarily from China, though some partnerships involved institutions in Europe and North America—while 11 publications were authored solely by North Korean researchers. Surgery was the most common subject, appearing in 20 publications; however, these articles were cited infrequently (an average of 1.4 citations per publication). In contrast, research in dermatology and traditional medicine demonstrated higher impact (10 and 4.7 cross-citations, respectively).
Conclusion
Our study clarifies the network of partnerships between North Korean medical educators and international institutions. We propose that North Korea’s capacity to engage in research meeting international clinical science standards may be greater than previously acknowledged, particularly in the field of traditional medicine.

Abstract PDF: Purpose
The peer review process is essential for maintaining the quality of scientific publications. However, identifying reviewers who possess the necessary expertise can be challenging. In Open Journal Systems (OJS), which is commonly utilized by journals, the most effective method of inviting reviewers is when they are already registered in the system. This study seeks to improve the efficiency and accuracy of the reviewer selection process to ensure high-quality peer reviews.
Methods
We introduced a process innovation to analyze users within OJS and obtain recommendations for potential reviewers possessing the relevant expertise for the manuscript under review. This study collected user data from OJS as potential reviewers and utilized information from the Scopus search application programming interface (API). We extracted authors’ data from the Scopus API to obtain their Scopus IDs, which were then used to scrape publication data of potential reviewers. The system matched the previous works of reviewers with the title and abstract of the manuscript using term frequency-inverse document frequency and cosine similarity algorithms.
Results
The system was evaluated by comparing its recommendations with the assessments made by the editorial team. This evaluation yielded precision, mean average precision, and mean reciprocal rank values of 0.47, 0.77, and 0.87, respectively.
Conclusion
The results clearly demonstrate the system’s ability to provide relevant reviewer recommendations. This system offers significant benefits by assisting editors in identifying suitable reviewer candidates from the existing user database in OJS, particularly for the evaluation of manuscripts.

Abstract PDF Supplementary Material

This review aims to provide guidance for those contemplating the use of ChatGPT, by sharing research trends and evaluation results discussed in various articles. For an objective and quantitative analysis, 1,105 articles published over a 7-month period, from December 2022 to June 2023, following the release of ChatGPT were collected. These articles were sourced from PubMed, Scopus, and Web of Science. Additionally, 140 research articles were selected, including archived preprints and Korean articles, to evaluate the performance of ChatGPT. The analysis of research trends revealed that related communities are rapidly and actively responding: the educational community is redefining its directions, the copyright and patent community is monitoring lawsuits related to artificial intelligence creations, the government is establishing laws to regulate and prevent potential harm, the journal publishing community is setting standards for whether artificial intelligence can be considered an author, and the medical community is publishing numerous articles exploring the potential of ChatGPT to support medical experts. A comparative analysis of research articles on ChatGPT’s performance suggests that it could serve as a valuable assistant in human intellectual activities and academic processes. However, its practical application requires careful consideration to overcome certain limitations. Both the general public and researchers should assess the adoption of ChatGPT based on accurate information, such as that provided in this review.

Abstract PDF Supplementary Material: Purpose
Although English has become the lingua franca for scholarly communication, scholars worldwide publish in other languages. Nevertheless, few studies have answered the question, “To what extent do scholars publish in non-English languages?” This study addresses that question, limiting its scope to Vietnamese scholars.
Methods
We reviewed 833 non-English documents authored by at least one scholar from Vietnam between 1960 and 2021, exploring aspects such as the language of the publication, the year of publication, the document type, number of document citations, the most prolific and most cited authors, and the primary research themes.
Results
Among non-English languages, French, Russian, and Chinese were the three most often selected by Vietnamese scholars for their publications. The year 2015 was a pivotal year when non-English publications from Vietnam significantly increased. Journal articles were the most common type of document, and the most frequent subject areas were medicine, agricultural and biological sciences, engineering, energy, and environmental science.
Conclusion
Although English is the primary language of science, the number of non-English documents by Vietnamese researchers has been increasing. This suggests that collaborative work between Vietnamese researchers and foreign researchers has also increased.

Abstract PDF Supplementary Material

This study investigated whether there was an increase in submissions to scholarly journals in Korea according to journals’ field and indexation status in Scopus or Science Citation Index Expanded (SCIE) in 2020, the year when the coronavirus disease 2019 (COVID-19) pandemic first spread throughout the world. The analysis included 60 journals with esubmission systems operated by M2PI. Yearly and monthly submissions were counted from 2016 to 2020. The yearly proportional change was also calculated. In 2020, submissions soared for medical journals indexed in Scopus/SCIE (49.5%), corresponding to an increase of 36.9% relative to the expected number of submissions. There was also a surge of submissions to these journals from March to July 2020. However, non-medical journals and medical journals not indexed in Scopus/SCIE did not show an increase in submissions. The number of submissions to scholarly journals in Korea was affected by the COVID-19 pandemic in a specific subset of journals. The background of the spike in submissions is required to be re-investigated. Editors’ burden also should be mitigated through editorial board members’ help and publishers’ support.

Purpose
The aim of this study was to characterize the network of institutions, journals, and topics of coronavirus disease 2019 (COVID-19) literature by Korean authors in the Web of Science Core Collection. The specific goals were to identify the collaborative relationships between Korean authors and international authors and to explore clusters of institutions, journals, and topics.
Methods
Literature was searched in the Web of Science Core Collection on January 30, 2021. The search terms were “SARS-CoV-2” or “COVID” or “novel coronavirus” in the subject field. The search results were limited again to “South Korea” as the country and the publication type of “article.” The measurement tool was Biblioshiny, an app version tool for Bibliometrix.
Results
Korean authors published 3.2 times more COVID-19–related articles in journals outside of Korea than in Korean journals. The journals showed three clusters by bibliographic coupling. In contrast, the co-citation network showed four clusters. Only a few journals were included in the clusters in both analyses. The conceptual structure of Keywords Plus by factorial analysis showed two clusters: “pathology and clinical treatment” and “knowledge and attitudes.” Institutions’ collaborative network consisted of four clusters. Korean researchers actively collaborated with international researchers, especially those in the United States.
Conclusion
Because only a few Korean journals were included in the journal clusters by both coupling and co-citation network, more active citation of Korean journals is recommended. The identification of human behavior as a distinct theme in COVID-19 research suggests a different focus in this area besides clinical studies.

Abstract PDF

Purpose
This study aimed to compare the length limits specified in the author guidelines with the actual length of abstracts in 90 journals in the fields of pharmacology, oncology, and neurology. Specifically, the following parameters were examined: abstract formats among the three subject areas; the relationship between the length limit and the actual length of abstracts; and actual abstract length according to the number of subheadings, the length of structured abstract subheadings, the length of frequently used subheading sets, and clinical trial registration information.
Methods
Thirty journals from each of three medical fields (pharmacology, oncology, and neurology) were selected from Elsevier’s Scimago Journal Rank. This included the journals indexed in PubMed from 2018 to 2019 that published the most articles. Article abstracts from these journals were used to create a dataset for this study. Descriptive, comparative, and correlational analyses of data for the three fields were conducted.
Results
The number of subheadings and abstract length increased in parallel. The Results component was the longest, suggesting that authors tended to use longer text to report results than for other structural abstract components. Authors generally utilized the length limit to a full extent without exceeding it.
Conclusion
The traditionally used 250-word length limit should be reconsidered for pharmacology, oncology, and neurology journals because it disregards the distinctive characteristics of abstracts and length differences between structured and unstructured abstracts. Various characteristics of abstract lengths presented in this study should be considered to establish more justifiable policies.

Purpose
This study examined whether article-level publication indicators were related to citation impact indicators in the business, management, and accounting categories listed in Scopus. Article-level publication indicators included the number of authors, countries, and keywords, as well as title length, while citation impact indicators included the field-weighted citation impact (FWCI) at the article level and Scimago Journal Rank (SJR) at the journal level. The optimal values of four article-level publication indicators for maximizing the FWCI and SJR were calculated.
Methods
All publication and citation impact indicators were gathered for articles and reviews in the business, management, and accounting fields published from 2015 and 2019 and listed in Scopus and SciVal. Correlations between four article-level citation indicators and each citation impact indicator were analyzed.
Results
The number of authors was positively associated with the FWCI, while the number of countries and keywords was not associated with the FWCI or SJR. Title length was negatively associated with the FWCI and SJR. The optimal publication indicators to maximize the FWCI were four authors, three more countries, six keywords, and a title word count of 14 to 19. The optimal publication indicators to maximize the SJR were three to four coauthors, three to four countries of collaborators, five keywords, and a title word count of two to seven.
Conclusion
Authors aiming to get higher citations and publish in higher-ranking SJR journals in the business, management, and accounting categories are recommended to pay close attention to design of research team and the number of keywords and impactful title length so that the publication will have a higher likelihood of being accepted and receiving citations.

Purpose
Stroke is a global economic burden of health, which means that it is critical to evaluate changes of optimal diagnoses and treatments. The aim of the study reported herein was to identify the most-cited articles in the field of ischemic stroke and assess their characteristics. Methods: We searched all included articles that had been cited more than 100 times using the “Cited Reference Search” in February 2016 from Web of Science Core Collection. Among a total of 2,651 articles, we excluded articles on basic science and which involved only hemorrhagic strokes and identified the top-100 cited articles on ischemic stroke. Results: The number of citations for the articles analyzed in this study ranged from 5,182 to 580. Most of the articles were published in The Lancet (25%) and Stroke (23%), and originated from the United States of America (n=44). Most of them were original articles (65%) and dealt with stroke risk factors (32%) and stroke management (30%). A novel study of hyperacute treatment involving recombinant-tissue plasminogen activator was described in the top-ranked article. Conclusion: Reviews on highly cited articles can help physicians identify trends in the diagnosis and treatment of ischemic stroke in the past. This bibliometric analysis can provide a unique perspective on historical developments in this field.

Abstract PDF

Purpose
An aim of this study is to analyze the citation impact of articles and reviews that were published in engineering, materials science, and medical journals in Korea over the 5-year period from 2012 to 2016 based on authors’ countries. These three subject areas were selected to provide insights regarding citation impact because they are better represented than other subjects among the 248 Korean journals indexed by Scopus.
Methods
We classified authors’ as Korean and foreign to assess and compare the citation impact of articles and reviews according to the authors’ countries and evaluated whether bibliometric indicators, such as the number of authors and the view count, were associated with a higher citation impact.
Results
We found that the citations count and publications in the top 10 citation percentile in these three subject areas were higher for reviews than for articles; further, the citation impact of articles and reviews by foreign authors was higher than that of articles and reviews by Korean authors. The number of authors had a weak relationship with citation impact based on the subject area, and the number of authors per review by foreign authors in materials science and medicine was negatively associated with citation impact. Moreover, the views count was found to be positively associated with the citation impact of publications in these three subject areas.
Conclusion
Considering these findings, future research should explore more bibliometric indicators, subject areas, and countries in order to develop practical applications. The results of this study provide insights and statistical evidence indicating that journal publishers and editors in Korea should attempt to attract more publications by foreign authors and promote their publications to increase their visibility and likelihood of being cited.

Abstract PDF

This study aimed to propose a tool for measuring the research performance of researchers, institutions, and journals in Indonesia based on bibliometrics. Specifically, the output of this measurement tool, referred to as the S-score, is described, as well as its implementation on the main database portal in Indonesia. The S-score was developed by a focus group discussion. The following 8 evaluation items for journal accreditation were analyzed in the development process: journal title, aims and scope; publisher; editorial and journal management; quality of articles; writing style; format of PDF and e-journal; regularity; and dissemination. The elements of the S-score are as follows: number of journal article documents in Scopus, number of non-journalarticle in Scopus, number of citations in Scopus, number of citations in Google Scholar, the hindex in Scopus, and the h-index in Google Scholar. The S-score yields results ranging from S1 to S6. The above metrics were implemented on the Science and Technology Index, a database portal in Indonesia. The measurement tool developed through the focus group discussion was successfully implemented on the database portal. Its validity and reliability should be monitored consistently through regular assessments of S-scores. The S-score may be a good example of a metric for measuring the performance of researchers, institutions, and journals in countries where most journals are not indexed by Scopus.

This study presents an update of a previous study, ‘Bibliometric analysis of publications from North Korea indexed in the Web of Science Core Collection from 1988 to 2016,’ which was published in Science Editing volume 4, issue 1. A re-analysis was performed because an incomplete search strategy was used in the original publication, and the present study analyzed the same bibliometric characteristics of publications from North Korea indexed in the Web of Science Core Collection from 1978 to 2018. The Web of Science Core Collection was searched by selecting ‘North Korea’ in the country field of the basic search results on July 31, 2018. A total of 533 articles were identified. There were no results from before 1978. China, Germany, and Australia were main countries of collaboration. Researchers from Kim Il Sung University produced the most articles. The main research fields were physics, mathematics, materials science, chemistry, and engineering. The funding agencies were mostly from China. The number of articles by North Korean authors only was 105, with the same main research fields. The results were almost the same as reported in the previous article, except for a much higher number of publications. The above results indicate that the North Korean government has asked researchers to publish their works in international journals; therefore, it has allowed them to access the internet. Based on the trends we identified, we anticipate that there will be a continuous increase in publications from North Korea in international journals indexed in the Web of Science Core Collection.

The aim of this study was to analyze the bibliometric characteristics of publications from North Korea indexed in the Web of Science Core Collection from 1988 to 2016. We hypothesized that the main research area would be the physical sciences, and that the number of articles would continually increase over time. The Web of Science Core Collection was searched using the terms “North Korea” OR “Democratic People’s Republic of Korea” OR “DPRK” in the address field of the basic search on February 2, 2017. The country of the co-authors, affiliations, journals, annual number of publications, and research fields were analyzed. Additionally, the articles by North Korean authors only were analyzed for the same parameters. A total of 318 articles from North Korea were found. The most frequent countries of collaboration were China, Germany, and Australia. Kim Il Sung University produced the most articles. The main research fields were physics, mathematics, and materials science. The categories of the journal titles corresponded to the research fields. The rapid increase in the number of articles in 2015 and 2016 was remarkable, although this increase started from a very small baseline number of publications. The results of the analysis of the 46 articles published by North Korean authors only were equivalent to the results for the 318 articles presented above. Our hypotheses were confirmed. The surge of articles in 2015 and 2016 may represent the recent efforts by the North Korean government to emphasize scientific research and development. It is anticipated that the productivity of North Korean researchers in terms of publications in international journals will increase dramatically based on the above trends, although the publication baseline is very low.

Abstract PDF

It aimed at analyzing the trends of international collaboration from articles indexed in Scopus by researchers in Korea from 2006 to 2015. The number of articles coauthored by researchers in Korea and those in selected foreign countries was obtained from document searches of the Scopus database. The growth of research collaboration in various academic disciplines was also studied. There were 22 countries which produced over 2,000 papers in collaboration with researchers in Korea during the ten-year period between 2006 and 2015. The average of the average annual growth rate taken over these 22 countries was 12.9%. In 9 additional Asian, Latin American, and African countries, more rapid growth of international research collaboration was clearly seen. Though research collaboration is most active in the field of physics and astronomy with most countries, it was found that the growth of collaboration in medicine was most remarkable in Southeast Asian countries. It may be originated from the intimate relationship between Korea and Southeast Asia and the leadership of Korean physicians in that region.

Abstract PDF Supplementary Material: Humanities and social sciences studies in Korea have remarkably low rates of co-authorship between professors and students. We chose a bibliometrics-based approach to characterize changes in the ratio of joint authorship between professors and students. Articles classified in the humanities and social sciences sectors that were published in journals registered in the Korean Citation Index during 2 phases over a 10-year period—2004 to 2006 (phase 1) and 2011 to 2013 (phase 2)—were used as the main source for the analysis. The study results can be summarized as follows: first, the overall number of co-authored articles drastically increased from phase 1 to phase 2; the percentage of co-authorship articles increased from 34.8% to 47.7%, and the percentage of co-authorship between students and professors rose from 9.9% to 20.7%. This trend was particularly noticeable in the social sciences, such as accounting, social welfare, and economics/business administration. Second, papers written by scholars from Seoul National University, Yonsei University, and Korea University were often published in high-impact factor journals. Among those articles, the rate of professor-student co-authorship increased by 21.6% for 7 years. Third, the increase in professor-student co-authored articles published in high- impact factor journals was even sharper. These findings indicate that perceptions of professor-student co-authorship have changed in the humanities and social sciences. In the near future, positive perceptions toward joint research and joint authorship between professors and students are expected to become more widespread.

Abstract PDF

We would like to verify the correlation among various citation indicators of 62 Korean scientific journals listed in the Web of Science (WoS) and Scopus. From a total of 85 Korean journals listed in both WoS as of January 2013, and 132 journals listed in Scopus as of 2011, 62 Korean journals listed in both citation indices were selected for analysis. Citation index indicators selected for analysis include impact factor (IF), 5-year impact factor (5yrIF), Eigenfactor score (EF), article influence score (AIS) (list of WoS indicators), SCImago journal rank (SJR), h-index, and impact index (ImIndex) (list of Scopus indicators). It took an average of eight years for a newly founded journal to be listed in Science Citation Index Expanded (SCIE). Since the IF, ImIndex, and AIS values failed to exceed 1.0, Korean journals’ popularity and prestige were confirmed to be minimal. Analyzed journals that were written in English exhibited higher SJR and h-index values than ones written in Korean. WoS’ IF exhibited a correlation with WoS’ 5yrIF, EF, AIS, and Scopus’ SJR, h-index, and ImIndex. Since the ‘popularity and prestige of Korean journals’ have been confirmed to be minimal, steps must be taken to improve this status. Popularity-based indicators have been shown to strongly correlate with prestige-based indicators in Korean science journals. Therefore, there must be a strategic approach taken to improve IF values.
