탁상출판이란 말 그대로 책상 머리맡에서 이루어지는 출판작업을 의미한다. 즉 컴퓨터를 이용하여 원고를 작성하고 편집하며, 인쇄작업까지도 일괄처리하는 것을 말한다. 종래의 출판과정이 얼마나 복잡하고도 많은 시간을 요구하는 수작업들로 일관되어 왔는지 일반 사용자들이 알고 있다면, 그러한 번거로운 과정들을 훌훌 털어버릴 수 있다는 사실만으로도 탁상출판의 매력을 느낄 수 있을 것이다.

The LCD monitor market enjoyed rapid growth in 1999 but only experienced modest growth in 2000. It is now poised for rapid growth from 2001 to 2005 as prices and costs decline. Price reductions will enable LCD monitors to move beyond limited vertical markets and extend into the broader consumer markets. This article will examine the future outlook for LCD monitors and provide a growth forecast.

Since the apple company adopted the desktop-office metaphor in Macintosh, the metaphoric interface has been used generally in multimedia products or services, on which user-friendly knowledge, conception, and images are represented metaphorically. Although the metaphor can be employed as one of ways to identify the essence or pattern of information, a theoretical framework on its relation with the user interface is not fully established. In this study, the user interface considered as a core of multimedia design was discussed, and the form of the graphic metaphor was investigated. The seven forms of the graphical metaphor presented herein would be applied as one of approaches to the user interface in relevant researches.

This study develops a GIS-based system which examines the adequacy of the Groundwater development project before the actual designing of the project. Using the system developed here, we can transfer simulation results obtained by WHPA regarding Groundwater levels in new development projects into GIS. We can also judge whether a Groundwater development project should be permitted through examining overlaps of the effects of the development and comparing with other pollutants. Since a two-tiered system which shares DB using inter- and intranets is developed, all the departments in the ministry of agriculture and forest and the agriculture base corporation can share accurate, reliable and latest information related to Groundwater.

The proposed internet disk for mobile devices is a new technique in order for mobile devices to recognize remote storage spaces as local storage card. The proposed technique is not to upload and download data of remote sites. It virtualizes remote storage space as local storage of mobile devices. Then mobile users can use the virtualized storage space as their local storage card. Also the remote storage space can be virtualized to desktop as local hard disk. It is possible to share data between mobile devices and desktop through the proposed internet disk.

As to the recent advances in computer technologies and high-speed networks, telecommunication services and provision of multimedia services will be provided on the basic of a new software architecture adapting networking infrastructure on open information networking architecture. In this paper, the video conference services has been selected as a target service example because it is expected to become one of the most important services on the full service network. In fact, it can be viewed as the basis for providing telecommunication services such as video telephony and video conferencing. This paper presents the prototyping of TINA (Telecommunication Information Networking Architecture) based desktop video conference system using the concepts of session management. The prototyping of desktop video conference system aims at assessing TINA concepts and refinement of the mapping between session graph and connection graph, and provides object modeling methodologies towards distribution and objected-orientation.

Recently, Virtual Desktop Infrastructure (VDI) has been widely adopted to ensure secure protection of enterprise data and provide users with a centrally managed execution environment. However, user experiences may be restricted due to the limited functionalities of thin clients in VDI. If thick client devices like laptops are used, then data leakage may be possible due to malicious software installed in thick client mobile devices. In this paper, we present Data Firewall, a security framework to manage and protect security-sensitive data in thick client mobile devices. Data Firewall consists of three components: Virtual Machine (VM) image management, client VM integrity attestation, and key management for Protected Storage. There are two types of execution VMs managed by Data Firewall: Normal VM and Secure VM. In Normal VM, a user can execute any applications installed in the laptop in the same manner as before. A user can access security-sensitive data only in the Secure VM, for which the integrity should be checked prior to access being granted. All the security-sensitive data are stored in the space called Protected Storage for which the access keys are managed by Data Firewall. Key management and exchange between client and server are handled via Trusted Platform Module (TPM) in the framework. We have analyzed the security characteristics and built a prototype to show the performance overhead of the proposed framework.
