In this paper, we presented a burst error reduction scheme at ADSL descrambler. Firstly, we discussed two scrambler types in frame-synchronous and self-synchronous as well as the ADSL scrambler structure specified in ANSI T1E1.4 standard. Then, we showed strong burst error could be happened at descrambler output from small timing error which is tolerable for network/local timing reference. After that, a new descrambler with parallel error detectors is prposed in order to reduce the burst error. The proposed scheme always selects the best data sequence using delayed error detector filters. Some experimental results are presented to verify the effectiveness of our scheme.

The ABEEK accreditation systems were introduced in Korea in order to ensure the quality of engineering education with global standards of engineering education and the mutual mobility of technical personnels between relevant countries. The ABEEK systems have a close relationship and a good compatability with ABET systems of the United States while have not been much investigated on the compatibility with EUR-ACE systems of Europe. In this paper, we first introduced the ABET, ABEEK and EUR-ACE engineering accreditation systems for the computer engineering educations, and presented a plan to ensure the interoperability between accreditation systems by comparison with their requirements.

IT governance becomes one of hot issues in corporate information system including university ERP. IT governance provides IT value and mitigates IT-related risks such that the organization takes new business chances and grows in the future. In this study, we briefly introduced IT governance and university ERP in the viewpoint of alignment to the business goal of the organization. And then, we proposed an strategic approach of IT governance for university ERP system with new performance evaluation items from IT-BSC. Finally, we pointed out some related research topics as further studies.
