Objectives : This study seeks to grasp the current status of Koryo medical research in North Korea, by focusing on researchers and research topics.
Methods : A network analysis of co-authors and keyword which were extracted from Koryo Medicine ― a North Korean traditional medicine journal, was conducted.
Results : The results of author network analysis was a sparse network due to the low correlation between authors. The domain-wide network density of co-authors was 0.001, with a diameter of 14, average distance between nodes 4.029, and average binding coefficient 0.029. The results of the keyword network analysis showed the keyword “traditional medicine” had the strongest correlation weight of 228. Other keywords with high correlation weight was common acupuncture (84) and intradermal acupuncture(80).
Conclusions : Although the co-authors of the Koryo Medicine did not have a high correlation with each other, they were able to identify key researchers considered important for each major sub-network. In addition, the keywords of the Koryo Medicine journals had a very high linkage to herbal medicines.
