On April 22, KIHASA held a Former Presidents Invitation Seminar, inviting the 23rd president, Dr. Kim, Sang-ho, the 24th president, Dr. Cho, Heung-sik, and the 20th and 21st president, Dr. Kim, Yong-ha. The former two attended the seminar, but the latter was unable to attend in person and sent a video message instead. The seminar, titled, "The Trail Left Behind and the Path Lying Ahead for KIHASA," was also attended by KIHASA senior managers and other researchers and administrators who shared their memories and insights together with the former presidents connecting KIHASA's past, present, and future.
