Lecture in Korean for the first time since 1996

I could not realize that it would be the first lecture in Korean since 1996. I was invited to Korea for special lectures and conferences but they were conducted in English. The thing I found from this lecture in Korean at Shilla University, 26th of April, 2007, was that it was not easy at all to talk about something even in your native tongue. I really appreciate the offer of Professor Park, Shilla University and those students who were forced to attend and listen to my somehow out of touched lecture.
