Smartphone is affecting not only our everyday life but also our business, directly causing diverse side-effects. But up until now, many researches that have been conducted on smartphone were focused on continuance intention for smartphone use and user satisfaction. Thus, the objective of this research is to investigate the effects that smartphone dependency has on digital dementia which is one of negative effects of smartphone. For the purpose, we have reviewed studies that are related to perceived characteristics of existing smartphones. As perceived characteristics variables, we have adopted perceived ease of use and perceived usefulness. And to present our research model, we have adopted smartphone dependency as psychological attitude variable and digital dementia as consequence variable. To implement an empirical analysis of our research model, we have conducted a survey with college student groups as research target who use smartphone most.

This study aims to propose an implementation plan for ensuring the digital continuity of university information resources that require the continuous management of temporary and permanent records in digital transformation environments. Thus, the cases of The National Archives (TNA; United Kingdom) and the National Archives of Australia (NAA)'s digital continuity policies were investigated and analyzed, drawing implications for ensuring universities' digital continuity. The process for ensuring digital continuity proposed by TNA was then applied to a university case for the proposal of an implementation plan applicable to university information resources.

Information management area faced new challenge arised from the developments of the computer and the information network, and the advent of information super highway. With deep perception of importance of the information, developments of information technologies, and change of the users' environment, we came to envision the digital library. This paper intends to describe the concept and function of the digital library, and to examine some of information technologies such as CD-ROM, OCR technology and image scanning, hypertext, hypermedia and multimedia. And it also considers the strategies for electronic information services and the applicability of the current information technology for digitalization by case studies of the existing database systems.

A digital library could be understood as not a part of information cycling, but whole process of information production, circulation and reproduction. This study suggests that a digital library should be a creator as which it is publishing, circulating, and re-producing the information resources. Therefore, the role of intrinsic DRM (Digital Resources Management) can be interpreted as a digital library. Open access model have been already adopted to many university libraries, many university libraries are publishing free access online research resources by themselves. Also, research collection based on cloud computing can be extended to networked research collection and share with other university libraries. These evidences show future library can be the digital library with online and open accessible publishing function.

The Internet provides a new way of doing business, but ease of copying and of sharing valuable digital information illegally across the Internet undermine many viable business models. This paper investigates the Digital Rights Management(DRM) as a means to provide safe protection and proper delivery of digital contents through the Information highway. First, we briefly summarize the current endeavor of DRM technical development and standardization process held in key technical working groups. Then, the paper provides a generic architecture for a DRM framework and shows the implementation of a prototype of DRM system incorporating key conceptual and technical standardization development. This study emphasizes the importance of developing the DRM architecture that provides the proper protection and safe transformation of digital contents in electronic commerce.

This study introduces the integration-style knowledge management of digital libraries in extended library concept, for integrated knowledge system which can provide various types of knowledge, and presents the knowledge-rump-type knowledge management model. By applying the model to the cases of several institutions, the processes and levels of extension are analyzed, and the important tasks for activating knowledge management are suggested. The knowledge pump embodies ideal roles of the digital libraries that activate the acquisition and distribution of knowledge. It is significant that the digital libraries, which used to remain as a simple application of information technology, not only present logical basis and way for extending their roles and areas, but also explain the implementation methodologies.

This paper also suggests the Digital Evidence Transmission System for E-Discovery which is suited to domestic environments in order to solve these problems and promote safe and convenient transmission of the electronic evidences. The suggested Digital Evidence Transmission System for E-Discovery is the system that submit digital evidences to Court's Sever through the Internet using Public Key Infrastructure and Virtual Private Network, and solves the problems - such as privileged and privacy data, trade secret of company, etc.

Effective resource management in the digital library should be implemented for the whole accessible sources on the network including multimedia one such as image files other than texts which focus on books. Contents management can be resource management of digital library in terms of wide scope, moreover, it\`s main function is to provide effectively tailor-made knowledge contents for users\` diversified objective of information usage. In this study, I examined main factors for more effective and advanced knowledge management including web resources under the current digital environment. First of all, I described closely several types of conceptualization and trails regarding more effective contents management and came up with advanced user-centered contents management system, i.e., user factors, intermediary factors, and finally service ones.

With widespread use of the Internet and improvements in streaming media and compression technology, digital music, video, and image can be distributed instantaneously across the Internet to end-users. However, most conventional Digital Right Management are often not secure and fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. In this paper, we propose the copyright protection using encryption of DCT coefficients and motion vector in MPEG-4 video codec of mobile device. This paper presents a new Digital Rights Management that modifies the Motion Vector of Macroblock for mobile device. Experimental results indicate that the proposed DRM can not only achieve very low cost of the encryption but also enable separable authentication to individual mobile devices such as Portable Multimedia Player and Personal Digital Assistants. The performance of the proposed methods have low complexity and low increase of bit rate in overhead.
