In the era of the 4th Industrial Revolution, manufacturing is the implementation of smart factories through digital transformation, and refers to consumer-centered intelligent factories that combine next-generation digital new technologies and manufacturing technologies beyond the existing factory automation level. In order to successfully settle such a smart factory, it is necessary to train professionals. However, education for smart factories is difficult to have actual field mechanical facilities or overall production processes. Therefore, there is a need for a system that can visualize and control the flow and process of logistics at the actual production site. In this paper, the logistics flow of the actual site was implemented as a small FMS, a physical system, and the production process was implemented as a digital system. In real-time synchronization of the physical system and the digital system, the location of AGV and materials, and the process state can be monitored to see the flow of logistics and process processes at the actual manufacturing site. The developed digital twin system can be used as an effective educational system for training manpower in smart factories.

Recently, there have been increasing studies on the application of digital technology, which has its focus of the irregular building. However, most of these studies have not clarified the objective of the technology and the effectiveness of professional manpower on its performance. This study analyzes actual used technology and the role of specialty contractor. It presents a framework to quantify the performance of the specialty contractor. For these purposes, this paper presents a proposed method to evaluate the activities of specialty contractors using a queueing model. As an attempt to verify the model, an actual irregular building project, in which digital fabrication is applied, is investigated during the construction phase. In order to collect the digital fabrication data, digital fabrication reports and specialty contractor's work log of project are reviewed. In addition, Digital Fabrication input personnel, productivity data are collected through interviews with experts involving in the case project. Analysis of specialty contractor's performance in digital fabrication reveals that the wait status of project participants varies probabilistically depending on the digital technology application level. The results of this study are expected to contribute toward the improvement of the production level in the construction industry.

Korean Government has invested a lot of efforts on digital contents industry. It believes that the digital contents industry enables Korea to regain the reputation of the most powerful IT country. Among its various efforts to promote the digital contents industry, a Digital Contents Identifier System, called UCI(Universal Contents Identifier), has been developed and deployed. UCI has provided a critical infrastructure for digital contents production and distribution. Thanks to Korean Government's efforts, users (companies and individuals) have currently registered 3.8 million digital contents through 25 RA organizations. Although the number of registered contents has been increased rapidly, many organizations hesitate to adopt the UCI system due to the lack of visible and short-term returns from the UCI system. Thus, this research tries to explore factors which affect UCI user satisfaction. This research finds that user's awareness, information quality, and service quality are the critical influencing factors toward UCI user satisfaction. In addition, this research finds that the critical influencing factors in public organizations are different from the critical influencing factors in private organizations. These findings hopefully provide useful guidelines for disseminating the UCI system widely.

In recent years, electronic technologies are rapidly changing the library's approach to collection management. In digital age, collection is a hybrid, that is, a mix of analog materials and digital information resources. But electronic publications are both a blessing and a curse for libraries. And the rapid acceptance of electronic resources raises many misconceptions and myths about their capabilities. This paper analyzes the digital paradox of current collection management from six standpoints : production of digital informations : digital scholarly communication : digital access paradigm : acceptance of e-journal package web collection development : digital archiving. Nowadays the pragmatic view of library is a logical information gateway to its own services and those of other libraries and information providers. Libraries and librarians need a concept and strategies of the hybrid collection management that reflects digital reality.

Currently, the field of textile is expanding the scope of its research, which focuses on non-material values such as emotion. This study suggests possibilities for and applications of emotional textile design, using digital craft via empirical research focusing on the emotional significance of textile design. The results, obtained with a subjective evaluation scale developed for this study, were used to verify whether there is statistical significance in the differences between textile design using digital technology and textile design using digital craft. The experiment indicated certain meaningful implications for application of digital crafts through the application of textile design. First, ethnic emotions were not found to be significant but did increase in all three comparative analyses. Second, both modern and classical emotions decreased. Third, comparisons between digital textile machine and digital textile machine and craft showed a significant difference in sensibility. Lastly, the comparison of 3D printing and 3D printing and craft indicated a significant increase in elegance. Therefore, textile design using digital craft is thought to be able to deliver an ethnic, fun, and elegant sensibility, following the digital technology used. If the results derived from this study are used appropriately in the development and production of textile design, it can effectively support the development of emotional textile design. In addition, the results of this study provide objective data for the design of emotional textile through digital craft, which will provide important implications for the academic world and for practical production.

This paper proposes a Distributed Transaction models based on the multimedia framework (MPEG-21) in digital convergence environment. Digital media market is growing up rapidly according to the extension of internet and universality of multimedia contents. So, importance of the effective management with the production and distribution of produced multimedia contents is becoming larger. For effective management of multimedia contents, the multimedia contents which are represented with different standard each other can be processed adaptively in the variable network environment. A free compatibility among the different terminals and standards are the essential particular should be offered for the digital convergence environment. A multimedia framework supports this compatibility and various multimedia services. In this paper, the Distributed Transaction models that multimedia contents can be circulated among the individual users safely and freely are proposed and the relation technologies are described.

Expansion and enhancement of information and communication infrastructure can create a market closer to an ideal type for a perfect competition, utilizing a cyber space in the network (with the expanded usage of Internet and e-commerce) and it could be a market of a monopolistic form. The government can take one of the two approaches responding to this monopolization of the digital market. First, the government maintains laissez-faire policy since the monopoly cannot be maintained over a long period of time due to an increasing in the production, decrease in the price, profit resulting from this and rapid technology evolution. Second, the government can actively interrupt the monopolization of the digital market. Monopolization in a digital market can lead to a market failure. Unstable market structure and too much frequent merger and acquisition contribute to making the digital market very dynamic. Information goods exchanged in the digital market have the features of very low marginal cost required to copy the original product whereas its initial fixed cost is very high. This explains why the information products are not priced based on the existing marginal price determination principles and why companies producing them have various product sales strategies (price/product differentiation strategy, and other sales strategies).

Marbling dyeing technique shows beautiful flowing pattern because the pattern is transferred to the medium by the pigments floating onto the viscous solution base. However, this marbling pattern does not have any reproducibility and the result of accidental pattern formation. Marbling process contains many complicated procedures such as making marbling base, mordanting the medium, and bubble removal with size limitation. Computer changed the many aspects in textile design and digital technique is used in many design production. However, it is impossible to produce marbling pattern with digital drawing. In this research, the digital textile design starting from marbling pattern was developed for digital textile printing. Marbling was done to produce the initial motifs and scanned. Several marbling media such as silk, polyester, and paper were used. Photoshop was used to process and develop textile design based on these marbling motifs. One repeat was developed and various colorways were tried. The developed textile design were printed using DTP.
