According to the IT839 strategy which was announced by the Ministry of Information and Communication(MIC) in 2004, the convergence trend of the broadcasting and the communication would be much more promoted. Thus, the methods for protecting the broadcasting contents will be indispensible elements for the successful IPTV service achievement. This paper describes the characteristics of IPTV and the related contents protection techniques. To evaluate several security issues, we suggest a security model for IPTV, and speculate the most widespread, two security technologies for IPTV such as CAS and DRM.

It is necessary to draw up many plans to solve problems in the management of groundwater resources in Jeju Island while systematically develop and utilize water resources at an optimal level. It also seems to an evitable option to establish Groundwater Management Areas in Jeju Island. The excess use of groundwater could be discouraged by imposing charges on those licenses. Such policy as allowance trading system do not appear to be because of transaction costs, but could be applied if only were accompanied by complementary method. The methods of using and conserving the limited resources of groundwater should be founded through socially agreeable and appropriate ways. The policy complemented allowance trading system by Pigouian tax could be effective to regulate licenses. This is cutting the numbers of licenses at a constant rate, imposing charges on those who want to continue using licenses, and reimbursing in cash to those who return the licenses.
