June 30, 2004 A long long time I have never updated this website. In this month I finally finished the graduate school study and received the Master Degree in Computer Science. Thanks God!! Sept. 24, 2001 Ok, I am going to finish my first English edition in my new website. This is just a prototype, or say the beta edition, at this moment. Due to the limited time, I am publishing these homepages right now. And I will update it ASAP.
