On Aug-30, 2016, our school had a retirement ceremony for Prof. Whang, ACM/IEEE Fellow, and a distinguished prof. at KAIST. I have prepared the ceremony with other staff members (Mr. SeoSik Shin and Mr. DaeJong Kim). It required lots of communications and efforts, but I was very happy to see that the event turns out well. Prof. Whang will continue his academic career at DGIST, another science research oriented school like KAIST.
