However, I felt only software is not enough. Therefore, I studied electronic and electrical engineering as a double major. I had worked for three years and I had decided to remain to be an engineer. But it's very tough in Korea. So I want to get a job abroad. As I studied electronic and electrical engineering, I got interests in system LSI and digital circuit design. I want to work on this area. Honestly, I have no experiences on it and it's not easy for me now. Therefore, if I can work on software and cooperates with system LSI, it may be very good. I want work which is very suitable for the engineer who knows both software and hardware. ------------------------------------------------------------------------------ Taeho Oh ( ohhara@postech.edu, ohhara@plus.or.kr ) http://ohhara.sarang.net Postech ( Pohang University of Science and Technology ) http://www.postech.edu PLUS ( Postech Laboratory for Unix Security ) http://www.plus.or.kr ------------------------------------------------------------------------------
