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.

Scopus收录的韩国工程、材料科学、医学期刊引文影响力对比韩国与外国作者

目的：本研究的目的是分析 2012 年至 2016 年 5 年间，根据作者所在国家/地区在韩国工程、材料科学和医学期刊上发表的文章和评论的引用影响。选择这三个学科领域是为了提供有关引文影响的见解，因为在 Scopus 索引的 248 种韩国期刊中，它们比其他学科具有更好的代表性。方法：我们将作者分为韩国人和外国作者，以根据作者所在的国家/地区评估和比较文章和评论的引用影响，并评估文献计量指标（例如作者数量和查看次数）是否与较高的引用相关影响。结果：我们发现，在这三个学科领域中，前 10 位引用百分比中的引用次数和发表论文的评论高于文章；此外，外国作者的文章和评论的引用影响高于韩国作者的文章和评论。基于学科领域，作者数量与引文影响的关系较弱，材料科学和医学领域外国作者每次评论的作者数量与引文影响呈负相关。此外，我们发现观看次数与这三个学科领域出版物的引用影响呈正相关。结论：考虑到这些发现，未来的研究应该探索更多的文献计量指标、学科领域和国家，以开发实际应用。
