The purpose of this study has its meaning to indicate the direction on collection and preservation of national literature which is one of the must important functions of the Central National Library. The Central National Library is, however, a representative library of our country and collect every kind of literature and to meet the requests of its users, the present situation of The Central National Library can't be performed sufficiently on these actions. According to studies of this paper, it have suggested the following five methods as a method of collecting national literature. First, the method by registering copyright endowing the number of copyright like ISBN. Second, the method a n.0, pplied by revising and su n.0, pplementing present legal deposit system. Thirdly, the method that the central one institution secure national budget collect literature of nation i.e., central intensive collection one. Fouthly , method of collecting literature by partial charge through local library networks. Fifthly, method by subject intensive collecting. As the preserving method of national literature, this research has indicated the following two ways. First, to keep the literatures forever, the method of The Central National Library keeps records as a limited volume. Second, The method of dispersing records as the local libraries. To put these methods into practice, it must be preceded that not only national helps, budget secures are needed but special committee must be organized to keep and preserve national literatures and material range also be extended and bibliographies for information data issuing must be worked out.

The new article, related to temporary copy on exploitation of copyrighted works, has been introduced in the copyright law as partly revised on December 2, 2011. While number of researches on in-network caching including Content-Centric Networking are conducted quite actively in recent years, the need for legal and institutional considerations has arisen since temporal storage (i.e. temporal copy) may be made not only at user devices but also in routers such as network equipments. This paper examines issues on temporary copy of copyrighted works mainly focusing on the articles and the related articles of the recently revised copyright law as well as the Free Trade Agreement between the Republic of Korea and the United States of America and further studies necessary institutions required to actualize in-network caching.

Channel of distribution of contents of digitalised multimedia contents is changing in form passed directly to consumer from manufacturer through digital network of high speed. Together, diffusion of various digital equipment that do is changing Past multimedia consumption structure with the wonderful speed so that can consume easily digital contents. Specially, Multimedia Personal Computer and fast diffusion of a digital television are acting role such as catalyst that promote easy purchase and consumption of multimedia contents of good qualify. However, this system is no method that can sell digital contents and express right that original owner for the contents can insist nothing but consume. Because consumer can distribute to another person copying contents that buy because of and user can distribute producing ashes again according to necessary field by oneself as well as, can lose meaning for original contents. In this paper, Text editing system for XrML (extensible Rights Markup Language) that describe about integrity of message and entity authentication in addition to necessary rights, fees, condition etc. and this to do fetters XML (eXtensible Markup Language) for copyright protection for digital contents in treatise that see hereupon and use digital contents design and embody.

음악 표절 분석은 특정 수치로 정형화된 사례가 없다. 음악과 관련된 표절 시비는 모두 전문가의 감성에 의존할 것이 사실이다. 따라서 전문가 사이에 감정이 개입될 여지가 있기 때문에 표절 시비가 끊이지 않는다. 따라서 본 논문에서는 지금까지 사람의 감성에만 의존하였던 음원의 표절 분석을 시스템적으로 분석하기 위해 필요한 음원 요소에 대해서 연구하고자 한다. 따라서 음악 표절 분석을 위해 필요한 음원 요소에 대해서 분석하고, 분석 시스템 구현에 필요한 MusicString 문법에 대해 기술한다. 또한 구현에 필요한 AST 구성과 유사도 알고리즘에 대해서 기술한다. 본 논문은 향후 음악표절 분석 시스템을 자동화하기 위한 초석을 마련할 수 있으며, 검수자의 감성에 의존하는 표절 관련 시비를 조금이나마 개선하고자 한다.

The purpose of the study is to analyze the factors which cause the deviations of e-piracy. For this, empirical data were collected by conducing a field survey with a total of 531 collegians, and a Structural Equation Model was used for the purpose of analyzing the data acquired by that. A Structural Equation Model was designed and constructed by such factors as Anonymous Environment, Norm-Consciousness, and Recognition on Penalty, which are considered as the direct variables. In addition, the factor of Anonymous Environment was set as a variable for the factors of both Norm-Consciouness and Recoginition on Penalty. These are the results of the analysis; it is found that Anonymous Environment is the direct cause of e-piracy, but the other two factors are not statistically significant. And it is also found that Anonymous Environment gives a direct influence on the other factors of Norm-Consciousness and Recognition on Penalty and it also gives indirect influence on the factor of Recognition on Penalty by means of the factor of Norm-Consciousness. Therefore, in order to prevent e-piracy, it is required to provide the proper opportunity to be trained to observe norms under the environment of anonymity. For this, diverse and effectual teaching methods for information ethic education should be sought.

This thesis will select one of the books that went out of print, and republish it using the ePub and PDF format to observe the effective and economic method to republish it as an e-book. Conclusively, e-book in PDF format was advantageous over ePub production. The ePub has limitations of electronically publishing the books went out of print prior to 21st century when storing the original text was not common, as well as book with complex layouts. The PDF format was able to capture and recreate the sensitivity that can only be presented by vintage books, also adding to the cultural value. To publish PDF e-books, the foremost requirement is to prepare a standardized system that allows comprehensive browsing of the current status of the book, and also creating an environment for copyrighted publishers to more actively publish e-books by diversifying the distribution platforms and properly allocating the profit generated by use of the copyright. This thesis provides a simulation of e-book publications, for small and medium size publishers and writers who are hesitant to publish e-books, to take more aggressive approach in entering the business.
