The mobile devices and cloud computing technology introduced new content services such as N-Screen service. The DRM techniques have been developed to support interoperability and multi-platform for new environment of content service. Nevertheless, it is still inconvenient for the consumers to purchase a new DRM-supported device or to migrate some purchased contents into new device due to the change of the subscription of service. Therefore, in this paper, cloud-based DRM model which is referred as DRMaaS (DRM-as-a-Service) model, is proposed to allow the consumer to freely use and move some DRM-protected contents in various smart devices regardless of subscription of service.

This study suggested a scheme of revitalization and development of digital talking books(DTB) for the print disable people. In Korea, the number of print disabled people is quickly increasing because of increasing of the acquired blind and the elderly in population. To promote information service and to encourage active participation from the group categorized as print disabled people, library is required two distinctive considerations, design and implementation of authoring tool for DTB and policy and administrative consideration for revitalization for DTB service to the print disable people.

The National Library of Korea establishes an Act on Legal Deposit and Use for the Online Digital Products in 2007 and it is preparing an enforcement. The purpose of this study is to suggest rate base on legal deposit of digital products before enforcement of this bill. To reach the goal, this study reviewed the legal deposit acts on digital products in the world. Also the opinion of main stakeholders in this area was collected such as digital book publishers and music copyright association. In conclusion, this study proposed rate base of reimbursement for legal deposit of digital products.

The objective of digital preservation is to ensure that digital information survives in usable form for as long as it is wanted That is to ensure long-term access to digitally stored information. The preservation of digital objects involves a variety of challenges, including policy questions, institutional roles, legal and rights issues, metadata, and technical strategies. In this paper, I introduce the definition of digital object life-cycle of digital object and related archiving workflow which are basic concepts of digital archiving. Also I focus on the aspects of current techniques used in digital information preservation including technology preservation, emulation, refreshing, migration, encapsulation.

This paper tries to solve the problems which previous methods have the model using smart card for protecting digital contents. This study provides a contents distribution model to protect the rights of author, distributor, and user as well as user's information by using technologies such as cryptography, DRM(Digital Right Management), access control, etc. The proposed system is evaluated as the most safety model compared with previous methods because it not only solves the problems which the previous methods have, but also protects four type of risks such as use of contents which other mobile devices download, the attack on the key to decode the message, the attack on leaking the contents, and the internal attack such as an illegal reproduction.

One of the main goals of providing open access is to vitalize the exchange of academic information by allowing access to the scholarly research outputs for everyone without the legal, financial, and technical barriers. We regard the use of the institutional repository as an open access enabler. In this study, we tried to make the factors, which enable the successful deployment of the institutional repository, explicit. We utilized literature review and case studies to generate the potential success factors for the institutional repository deployment. We verified the factors by having in-depth interviews with the subject matter experts. The resulting factors were organized as organizational, political, and technical ones. The organizational factors included the strong open access support by the organization heads. Under the policy factors, a number of issues such as selection of the core contents, minimum quality control, protection of the copyrights, forming supporting groups through active advertising, long-term preservation, incentive, and mandate, were included. The technical factors included easy submission, support for interoperability, and support for the publication activities.

The accountability of cloud service which provides the cloud users with accountable services applies various technologies such as the compliance of service policy, monitoring and auditing, logging, and others. It ultimately intends to provide trustworthy cloud service by determining who is accountable for various problems happened during data processing and service offering. In this paper, we propose a cloud ecosystem formed from the chain of content and DRM Cloud service in order to offer secure and trust DRM cloud service when providing high value-added content service. Besides this, we analyse the requirements of cloud services for content owners and users and then propose some logging information to be recorded for trace of accountability and a structure of tool for monitoring.

DRM(Digital Right Management), which realize the controllability of intellectual right in the process of transactions with economically feasible cost, may cause critical changes in the distributions of digital contents. This Paper takes notice of the concept of 'Super Distribution' in which every user can be the core of the distribution and the possibility of usingvarious price structures by introducing DRM. We reviews that Super Distribution can increase the demand of digital contents by decreasing the information cost in the user aspect, and it can also diminish the distribution cost dramatically in the provider aspect. Also, DRM may allow various types of pricing which use different criteria such as the number or duration of usage. The variety in price structure can increase not only the profit of provider but the utility of consumer. These characteristics of DRM, as a whole, increase the efficiency of distribution and make the providers differentiate their services.

IR(Institutional Repository) is an indispensable instrument for not only long time preservation of intellectual products but also for shifting commercial publishing company-dominated academic communication stream. In Korea, dCollection project of Ministry of education, science and technology has contributed on immediate, integrated circulation of distributed research products. dCollection is already one of the few integrating instrument for distributed academic resources, but it has not been university's voluntary instrument to announce their research accomplishments and to realize open access. On the other hand, Japanese government has promoted universities' IR operation through "Next generation infrastructure construction project." Even though distributing speed is relatively low, each university made ripe operating skill by their selves and realize its own purpose. This study comparatively analyzed policy and current status of Institutional Repository in Korea and Japan from various viewpoints. And also it proposed directions of development about Korean Institutional Repositories.

In the 1970s, Korea actively produced so many animated works which is called the "golden age" of korean animation. However, Korea imported and subcontracted foreign animations than creating original works and, there has been a constant controversy that many of the korean animations imitated foreign works. Therefore, this paper aims to analyze the factors that caused this and its patterns, focusing on works suspected of plagiarism in Korean animation during the 1970s and 1980s. First, the focus will be on the definition and composition of plagiarism in art creation, secondly, on the political-ideological, industrial-administrational, production-structural, and copyright awareness aspects of the factors of plagiarized animation. Thirdly, 30 korean animations produced at the time will be analyzed on the degree of design theft and plagiarism based on six criteria focusing on characters' shapes and color arrangements. By analyzing the social factors and patterns of plagiarism, this study aims to provide a social and cultural understanding of academic value about the process of korean animation's development.
