Because of the development of digital technology, modern digital instrumentation & control systems are being innovativly developed in industrial plants. Whereas, many analog systems are still being used in nuclear plants, because of the demerits of digital equipment. As known, the demerits of digital equipment are the uncertainty and weaknesses in ambient environments such as smoke & electromagnetic interference In an Integral Reactor, a digital I&C system will be composed of microprocessor, memory and network card. Designers will apply new technique for digital equipment. Thus, it is important for digital I&C systems to operate according to designed functions & performance in the ambient environments during a life cycle. Digital I&C systems should have tolerance in such environments and environment qualification should be concluded To acquire electromagnetic interference qualification of digital equipment, this paper suggests an EMI test requirement. Designers should consider the electromagnetic compatibility and test digital equipment according to each test procedure. This paper involves an EMI test requirement and the results analysis of EUT(Equipment Under Test). Test result analysis will be used as electromagnetic compatibility design guides for Integral Reactor I&C systems.

Online game digital hanbok has an aesthetic value in a digital culture and is useful for developing a digital hanbok design for online games as well as other industries. This thesis analyzes its attire and design composition elements to design a 3D digital hanbok by utilizing its formative characteristics. The literature review defines them as transmutability, virtuality, fictionality, reality and playfulness based on the characteristics of digital media, late digital generation and online games. We analyzed 471 images from 50 online games. Sonmaep was used for making 3D digital hanboks. Its attire was grouped into jogori pants, jogori chima, po and armor. Its design composition elements were classified as pleat, layering mu or hemline, mu sub gyeopmagi mitbadae, vent, git dongjung and decoration elements. The results feature 8 digital hanbok designs. Reality designs are replicas of jogori daegugo for men and po for women in the period of the Three States. Virtuality designs are slightly changed shapes of yoseoncheolrik for men and white jogori yellow chima for women in the Koryo Dynasty. Fictionality designs are casual fusion armors for men and women as a hyperbolic form. Playfulness designs are doll costumes for men and jogori chima for women as a kitsch and childish style. The concept of online game digital hanbok escapes from conceptual limitations of traditional hanboks. This result can be used for designing digital hanbok contents in various industrial parts.

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.

Beyond the digital world from the analog age, the contents are very easily copied under the illegal conditions and these are rapidly distributed by the information super highway. The increase of ilegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Watermarking technology support to the legal users by the protection technique based chi the digital content copyright protection method(DRM). Most of previous digital watermarking have embeded to the content. In this paper, we have researched the standardization of digital rights management and developed more efficient watermark embedding method.

As digital cultural heritages have been applied to various fields, more systematic research on the domestic digital cultural heritage need to be improved. The EPOCH project by European Union contributed to standardization of ICT+CH domain, creation of network between different organization, and study of socio-economic impact of digital cultural heritage. We can find a way to improve domestic digital cultural heritage projects by analyzing EPOCH project in each management technique culture view. Based on these analysis this paper suggests the necessity to establish an independent research domain for digital cultural heritage, investment in heritage sites by private companies, and research to fit better with the user's need, and study on business administration in digital cultural heritages.
