Hello, Woo-Sup hyung, Kye-Sie, and possibly Yun-Sik hyung. This is Byong-Sun, remember me? Sorry that I couldn't keep in touch. How' are your lives these days? I visit Kids often(ID:dolphy). I actually send happy birthday MSG to you, Woo-Sup hyung. but, guess you didn't get it due to system malfunction. Kye-Sie,you have served your military duty and now deserve to rest. I'm happy to see people on the kids and see you around on Kids near future. Take care all, Byong-Sun Kim Interdisciplinary Design Optimization Lab Rensselaer Polytechnic Institute Troy NY 12180 USA kimb2@rpi.edu
