all paper published in KJA in 2020 were assessed using the source data collected from SCOPUS (http://www.scopus.com).

In 2020, the average number of citations per document was 1.303. The total number of authors was 364, authors per document was 4.28, and collaboration index was 4.17. The most productive authors are presented in Table 1 . We appreciate their contributions toward KJA through this editorial. Table 2 depicts the countries of the 12 corresponding authors in 2020. The country-based frequency of publication was as follows: South Korea (40.0%), India (19.0%), the United States of America (15.8%), Singapore (5.3%), Italy (4.2%), and others. Table 3 contains the most frequently used keywords in 2020, which consisted of the keywords used by authors, Keywords-Plus, and words in the title. Keywords-Plus, which is available on the Web of Science platform, automatically extracts information from the metadata of a particular research field, because indexing terms also assist in the determination of the knowledge structure, although it may be less comprehensive in revealing the intrinsic aim of a study. It seems that KJA tends to focus primarily on subjects such as regional anesthesia, postoperative pain/analgesia, nerve blocks, and COVID-19 in 2020 based on the results of the author' s keywords.

The bibliometric information of articles that cited the papers published by KJA in 2020 was downloaded from the Web of Sci- Table 4 contains the most relevant sources that cited the reports published in KJA as references during 2020. Table 5 lists the 7 most cited papers published in KJA in 2020. The two most cited papers were a case report of an emergency cesarean section in a patient with COVID-19 and an anesthesia recommendation editorial for COVID-19 patients [2, 3] . Last year, most journals mass produced COVID-19 related literature, and the citation of such studies has also increased. The next two most cited studies were two reports of ultrasound-guided regional blocks [4, 5] . The surge in the interest in multimodal analgesia is thought to have had a synergistic effect on interest in the literature on various regional blocks. Journals are competing endlessly for the attention of readers, considering that numerous papers are published every day. KJA will endeavor to strive to provide more useful information to its readers, as one of the journals that continues to grow in its field.

I sincerely appreciate not only all the authors who submitted the great works to KJA, but also all the editors and reviewers for their hard work throughout the year.
