The purpose of this paper is to examine the ethical implications in UCC participation. This paper aimed at examining the advent of UCC as a critical media tool in interactive two-way communication and the effect of ethical questions on the level of UCC participation. The findings show that uncertainty avoidance gives an positive and significant effect on privacy concern and regulatory preference, but it is not related to copyright invasion in Korea and U.S.A. It is shown that privacy concern does not influence on UCC retrieval in Korea whereas it is positively related to UCC retrieval in the United States. Also, privacy concern has not relationship with UCC production(modification, recreation, generation) in both nations. In the case of regulatory preference, it posits an significant and positive effect on UCC retrieval in Korea while it is not related to UCC retrieval in the United States. Also, regulatory preference does not affect on UCC production in Korea whereas it influences on UCC generation without impacting UCC modification and recreation in U.S.A. Finally, the results show that copyright invasion has stronger relationship with UCC recreation and generation than UCC modification, and it is positively related to UCC retrieval in both nations.

Distribution, duplication and manipulation of the digital contents are very easy due to the characteristics of the digital contents. Thus, damages of invasion of property right rapidly increase due to infringement of copyright for the digital contents. To prevent illegal use and to settle conflict about ownership of the digital contents, continuous efforts with enormous expense are devoted. In this paper, we design and implement real-time audio watermarking system to protect ownership and copyright for the digital contents. The proposed system also clarifies where the responsibility about the illegal distribution lies. The system has convenient user interface so that general administrator without an expert knowledge of the protection of copyright can use easily. In addition, unlike the traditional watermarking system, our system has merit to offer information about the illegal distribution for clear post-management.

As the innovative internet technologies and multimedia are being rapidly developed, digital content is a remarkable new growth industry and supplied by various channel. For example, domestic sales volume in digital contents marked an annual increase of 14.7% since 2003. Against the merits of digital content distribution, Information reengineering aspects are getting more serious issues in these days such as infringement of copyright, flood of inappropriate content, invasion and infringement of privacy, etc. In this paper, we are making a suggestion of the TDCDA-Trusted Digital Content Distribution Architecture in order to solve above problems. TDCDA is provided to how well-define and design the trusted path in digital contents distribution in internet environments using a secure distribution mechanism, digital content integrity and copyright protection. Finally, we also proposed the TDCDA algorithm and applicable guidelines for feasible approach in real computing environment.

In the forthcoming 21st century new technical and scientific developments in outer space demands new approaches towards the problems arising in several fields of the use and exploitation of outer space including practical applications. The main purposes of this study are to analyze the legal problems of geostationary orbital position, telecommunication, direct television broadcasting by uses of artificial satellites. Communication via artificial Earth satellites was one of the first applications of space technology and is now one of the most developed field. From the technical and economic standpoints the advantages of world-wide satellites communication system are too all obvious. However, as the practical uses of space technology become more freguent, the legal conflicts among nations have become more divisive. One of the problem grown in uses of artificial satellites is that of the increasing shortage of suitable orbital slot positions for satellites, especially in geostationary orbit. Legal status of geostationary orbit as a limited resourece have to be reviewed in consideration of the side effect of the "First use, first-served" principle. The geostationary orbit is to be used for the benifits of all mankind and to be guaranteed for each state institutionaly in order to have eguitable access to the use of the orbit. Rapid increase of satellites broadcasting system in not only developed countries but also in developing countries opened up new possibilities with one another's scientific and cultural achievements. But there is also a potential danger that this powerful new instrument of influencing public opinion will be abused. Such a danger incudes spill-over or harmful interference. This controversial issue brings about the question whether prior consent from the receiver nation is needed to broadcast across international boundaries. Some states have rejected prior consent because it interfere with the free flow of information. Many other countries have opposed that opinion as an invasion and violation of sovereignty and as a violation of the 1967 Treaty and the UN Charter. Since declaration of the First Year of Outer Space in 1985, our country have promoted the plan of launching communication and broadcasting satellites. With the Koreasat launched in 1995 as the start, a real satellite-telecommunication era was opened in korea. According to this new development of our country, there will also rise various legal problems related to satellite broadcasting and telecommunication such as the inflow of foreign programs, the permeation of culture and the infringement of program copyright. Consequently the effective reactions to these problems in satellite-communication era should be tried including international cooperation. It is therefore to take into careful consideration the legal issues which may arise in outer space activities and to formulate positive policy on international cooperation with surrounding or advanced countries and international organization concerned. For this purpose the United Nations also prepares the UNISPACE III in 1999, to enable the international community to meet a more promising 21st century.
