On the 18th of December, the successful defence took place presented by Pavlyk Anatolii who is the apprentice of Arkadii Zhulavskyi, PhD. This the 12ve PhD student who performed successfully under the supervision of Professor Zhulavskyi. We asked our colleague, what is his motivation in contributing to PhD training. “When I work with youth, I myself am becoming younger ”, Arkadii Yuriyovich told us. “It is the cooperation with PhD students that brings the insights, new ideas, new approaches to solving the existing problems”. Now the followers of Zhulavskyi work in Sumy, Kyiv, Shostka and many of them became Dr.Sci. and were elected to high offices. We congratulate and wish further success!
