Due to the rapid popularization of mobile multimedia devices and the Internet as well as the realization of high-speed data transmission and large-volume data recording media, high quality content distribution and ubiquitous information services are making progress and a new type of information distribution and network sharing service has gradually emerged into the market. It is capable of utilizing terabyte sized home servers also in private homes. Under these circumstances, in distribution of content over shared networks, it is crucial to establish DRM (Digital Rights Management) technologies to protect the content from illegal copying and usage. A truly successful DRM system must be built on open worldwide specifications and provide maximum interoperability and user acceptance. An open interoperability of DRM is able to construct highly expandable PKI based DRM, targeting usage between systems, considering the expansion of recent content distribution services and clients This document gives protocol specifications for the exchange of rights information between the DRM module, description of specifications for rights information and encrypted content formats.

This study analyses the relationships between the residents'personality and the residential types, and between the sense of crowding and the residential types. For this purpose, this study surveys two hundred ninety three residents in their thirties and forties, residing in Seoul. We find that there are differences in the personality traits and also differences in the sense of crowding according to residential types such as high-rise/low-rise apartments, high-class private residence, multi-family houses. And these differences are due to the differences of inner and outer residential environment satisfaction. The lower a resident's inner environment satisfaction is, the higher is his/her sense of crowding. And low environment satisfaction and high sense of crowding appears to account for one's depression and anxiety. Conversely, the higher environment satisfaction is and the lower the sense of crowding is, the higher is his/her responsibility. Finally, this study tries to examine how each personality trait changes according to the habitancy duration. We find that residents having a 3-5 year habitancy record are more anxious and depressed than those who have been living more than 7 years in the same residence.
