Abstract Scope |
We estimated the change in the number of doctoral degree holders (doctors) in computational materials science (CMS) in Japan during the last 50 years. We analyzed the subjects of more than 151 thousand doctoral dissertations in science and engineering (SE) found in a Japanese doctoral dissertation database using text data mining techniques. In Japan, the number of doctors rapidly increased during the 1990s due to a reorganization of the graduate school and peaked at approximately 2000. Then, it rapidly decreased due to the recent birthrate decline in Japan. However, we found that the number of doctors in CMS continued to increase until approximately 2010. In addition to that, the decrease rate of those after 2010 has been small. Therefore, the ratio of doctors in CMS to those in SE has continued to increase. This indicates that the importance of researchers in CMS has been constantly enhanced and recognized in Japan. |
