Legal Rules and Soft Law in Corporate Governance
The corporate governance models of US and UK have influenced many
countries around the world. After the Enron scandal in the US, merit regulation
on corporate governance by mandatory legal rules was enhanced by enacting
Sabanes-Oxley Act. On the other hand, UK kept on the soft law approach on
corporate governance suggested first by the Cadbury Committee. In the UK,
listed companies are required by the Listing Rules to disclose whether they
comply with the Code or explain the reason in case of the deviation from the
Code. This comply or explain approach has been followed by many countries,
including Germany.
In this article, the merits and weaknesses of these two comparable approaches
on corporate governance regulation are analyzed to provide some implications in
designing the regulations on corporate governance of Korean companies

provide high-speed data rate that can support the multi-media service. This paper considers the design of
WCDMA modem and implementation aspects. We propose the adaptive channel estimator, the enhanced power
control scheme, and the novel cell search technique. The performance of the implemented modem that
incorporate the proposed schemes are compared with that of the system with a conventional techniques. The
proposed system can provide the performance improvement by 0.5~1.0dB compared to the conventional system
