This study examined research performance of Korean physicists, comparing Korean-authoredpapers versus internationally co-authored papers, indexed in SCI, 1994-1998, and using thenumber of citations received by internationally co-authored papers covered by the SCI CD-ROM.For the study, 4,665 papers published from the researchers affiliated with the physics departmentsor physics-associated laboratories at Korean universities and indexed by SCI were analyzed.Korean authored papers tended to be published in Korean, Japanese, and UK journals, whileinternationally co-authored papers were more likely to appear in German, Dutch, and Swissjournals. Among the 18 authorship countries (on the basis of first author), 93 internationally co-authored papers by U.S. researchers had the highest citation rate, an average 15.9 citations perpaper. Of the eight countries that published over 5 papers, there was no correlation between theaverage number of citations per paper and the total number of citations. However, an ANOVAindicated a significant difference between the average number of citations per paper according tocountry (F = 5.84, p < 0.0005). In other words, papers by the U.S. and French researchers tendedto be cited more frequently than papers by the Italian, Japanese, Korean, Russian, and Germanresearchers.
This study investigates the scientific output and publication patterns of Korean biotechnology before and after the start
of the Korean Biotechnology Stimulation Plans (1994–2007), and then compares the results with publication data from the same
time periods for Japan, the People’s Republic of China, Taiwan and Singapore. For this study, 14,704 publications, published
by at least one researcher from one of the five Asian nations (indexed by SCI Expanded during the years 1990–1993 and the
years 2000–2003), were considered. A marked increase of Korean research output in biotechnology was largely influenced by
an increasing tendency for researchers to enter the field of biotechnology and by increased expenditures for R&D activity
through the Korean Biotechnology Stimulation Plans. In addition, the SCI Expanded coverage of national journals affected the
scientific output and publication patterns of Japanese and Korean researchers. Looking at the Korean publications by collaboration
type, international collaboration leads to more publications in mainstream journals of high impact factors than local and
domestic collaborations for the two periods. However, although the Korean Biotechnology Stimulation Plans were followed by
a remarkable increase in South Korea’s research output, this increase has not been accompanied by growth in the quality of
those publications in terms of impact factors of journals for Korean publications.
By comparing the citation patterns of Korean researchers in physics and mechanical engineering, this study identifies the
extent to which type of publication source (Korean non-SCI, Korean SCI, and international SCI) and type of authorship (purely
Korean authors, Korean-foreign co-authors, and foreign-Korean co-authors) influence the choice of sources cited by Korean
scientists. Koreans publishing physics or mechanical engineering papers in international SCI journals are more likely to cite
articles published in journals of the science mainstream countries (the U.S., the U.K., the Netherlands, and Germany) than
articles published in national journals, while Koreans publishing in Korean journals tend to cite articles published in national
journals. In terms of authorship, articles published in mainstream journals are more highly cited by internationally co-authored
papers than Korean-authored papers in both disciplines.
Summary This paper investigates Korean scientific output, focusing on international collaboration patterns, through an analysis of journal publications. For the study, 44,534 publications, published by researchers affiliated with Korean institutions and indexed by SCI during the six years 1995-2000, were considered. The study period was divided into two periods to compare the international collaboration for three years 1995-1997 and 1998-2000. The results show a clear decrease in Korea's international collaboration level between the study periods even though the number of researchers as well as the total R&D expenditure decreased considerably after Korea's economic change. The decrease of international collaboration in Korean science was inversely associated with different determinants such as scientific size as well as national scientific infrastructure. This decreasing trend of international collaboration in Korean science was largely caused by discipline-to-discipline variations in coverage of the SCI database. Among the top-ten collaborating countries, only the Chinese and the Canadian share of collaborative publications with Korea increased between the two periods under consideration.
This article reports findings from a study of the relationship between citation measures (impact factor and its quartile)
among international composition of editorial board and foreign authorship in 17 Korean SCI journals for the three 5-year periods,
1995, 2000, and 2005. With few exceptions, the relationship between international editorial board composition and foreign
authorship and citation measures was non-existent, at p > 0.05. However, the international members on editorial boards and foreign authorship of papers in Korean journals have increased
greatly over the three 5-year periods, and there has been to a certain degree growth in the visibility and performance of
Korean SCI journals in terms of impact factors, but not their quartiles.
