Abstract PDF Supplementary Material: Purpose: This study conducted a comprehensive analysis of North Korean domestic journals, using scientific quantification methodologies to identify prominent researchers and research areas within the field of chemistry.
Methods
Data were collected from the journal Chemistry and Chemical Engineering published in North Korea. Through an analysis of co-authorship relations and literature reviews of papers authored by researchers who were highly influential in research networks, core research areas were identified.
Results
The researcher with the highest number of publications in the given period was Yong-Chol Lee, with 31 publications, followed closely by Gyun Kim, who also demonstrated significant research activity. When focusing on the last 5 years, Myeong-Cheol Hong emerged as a prominent figure. Yong-Chol Lee has expertise across diverse fields of chemistry, including fine chemicals, biochemistry, and mineral materials. Gyun Kim, in contrast, is recognized for his in-depth knowledge of organics, enzymes, processes, catalysis, fine chemicals, and industrial chemistry. Myung-Cheol Hong’s research primarily centers around organic chemical synthesis within the fine chemical domain. All three researchers are making substantial contributions to the chemical industry.
Conclusion
The findings of this study provide valuable insights into research trends in the field of chemistry in North Korea and contribute to a broader understanding of the discipline’s internal knowledge structure within the global academic community. This research is anticipated to be especially useful for scholars who are analyzing bibliographic information pertaining to North Korea.

Purpose: This study aimed to investigate the distribution of research fields and diseases in the North Korean internal medicine journal by using a content analysis and a frequency analysis method.
Methods
All 2,092 articles published in Internal Medicine [Naegwa], a North Korean medical journal, from the first issue of 2006 to the last of 2015, were searched and classified by subspecialty of internal medicines, diseases, and classification codes of the Korean Standard Classification of Diseases version 6.
Results
In total, 1,392 out of the 2,092 articles were classified into the internal medicine field, with the remaining 700 classified as basic medicine, family medicine, or anesthesiology. Among the articles on internal medicine, most concerned the digestive system, followed by circulatory, respiratory, renal, and endocrine systems. Among the 700 articles in other fields, articles on gynecology were most common. According to the analysis of diseases, the most commonly studied in internal medicine were gastrointestinal diseases, hypertension, respiratory infectious diseases, glomerular diseases, and diabetes. Meanwhile, cerebrovascular diseases, herpes zoster, mental and behavioral disorders, and urinary tumors were most covered in the other fields. In the distribution by classification code of the Korean Standard Classification of Diseases version 6, circulatory and digestive diseases accounted for 42.4% of articles.
Conclusion
The results of this study are expected to be exploited to estimate the disease distribution and disease burden in North Korea.

Abstract PDF Supplementary Material

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.

Abstract PDF Supplementary Material

This study aimed at analyzing the bibliometric characteristics and content of medical articles from North Korea in PubMed and characterizing the patterns of international cooperation of medical researchers in North Korea. We hypothesized that the number of publications from North Korea in PubMed has increased recently as a result of active cooperation with foreign researchers. PubMed was searched on July 19, 2017 using the search term “(North Korea [Affiliation]) OR Democratic People’s Republic of Korea [Affiliation]) OR DPRK [Affiliation].” The content of medical articles was analyzed and cooperative work with foreign researchers was noted. The number of medical articles in PubMed through July 2017 was 16, of which 2 were by North Korean authors only. From the content of these articles, it was found that researchers in top-notch institutions, including Kim Il Sung University, can access the internet, and that a dental caries prevention program supported by Finland has been in place for more than 10 years. The number of publications from North Korea in PubMed has increased recently, although the amount is still very small. Providing internet access to North Korean researchers will accelerate their submissions to international journals.

Abstract PDF Supplementary Material

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.
