Kim (2001) conducted a research in the same level of aggregation as Cano, which was a specific discipline. However, Kim focused more on the research performance of the authors, which in this case were Korean physicists. Research publications data from 1994 to 1998 produced by Korean physicists were collected from the Science Citation Index CD-ROM Database.

Korean Physical Society and other physical society related in Korea published more than 10 journals in either English or Korean. However, Science Citation Index only included two Korean-published journals, namely Journal of the Korean Physical Society and Bulletin of the Korean Chemical Society.

A total of 4,665 publications produced by Korean physicists or researchers affiliated with physics departments or laboratories were found. These publications were spread over 224 journals produced by 19 different countries. US journals accounted for 37.5% while, followed by Korean and Dutch journals which accounted for 22.0% and 20.1% respectively. There were 33 journals where more than 30 papers had been published in the journals. These 33 journals accounted for 77% of the total number of publications. The top journal, Journal of the Korean Physical Society, accounted for 21.6% of publications.

Out of the 4.665 publications, 31.9% were authored collaboratively by Korean physicists or researchers with other researchers from other countries. Kim also noted that most Korean-authored papers were more likely to be published in Korean, Japanese, or UK journals, while internationally collaborated papers had a tendency to be published in German, Dutch or Swiss journals.

Kim identified the top 15 Korean institutions with more than 100 publications. These top 15 institutions contributed 86.4% of the total publications, with Seoul National University, Korea Advanced Institute of Science and Technology, and Korea University as the top 3 institutions.

Kim further investigated the impact of the publications by looking at the Journal Impact Factor (JIF) of the journals where the papers were published and also at the citation rates of the papers. First, 62.7% of the total publications appeared in the journals with a JIF (1998) greater than 1. Both Korean journals, which accounted for 22% of the total number of publications, had a JIF of less than 1. Secondly, based on the first authors of the publications, 18 authorships countries were identified. Kim found that US and French publications tend to get more citations with an average 15.9 and 16.4 citations per paper respectively, while Korean publications averaged 4.0 citations per paper. However, French publications had a significantly higher self-citations rate in comparison with US and Korean publications. 24.6% of the total number of citations received by the French publications was self-citations, whereas for Korea and US, only 14.1% and 8.2% are self-citations. Among the 18 authorship countries, papers authored by China’s researchers were the least cited with an average of 2.2 citations per paper and 25% of the citations received were self-citations.
