This study investigates successful overseas cases and projects of digital archiving of historical materials in order to develop continuous digital archiving strategies in this rapidly changing digital information environment. The analysis is based on the information life cycle perspective of collection, preservation, access and use of digital archives as well as the concept of digital curation. Through the analysis, the study proposes nation-wide digital archiving policies, long-term preservation and standardization strategies for continuous services, and collaborative financial support strategies between institutions and countries for successful digital archiving and continuous improvement.

The concept of "new consumer sovereignty" is playing a significant role in having the initiative of production and consumption of technology and culture trend. Today the 'new consumers' positively use digital and information technology in purchasing. To understand these consumers' new purchase tendency, the study examined the actual conditions 1) of consumers' use of digital and information technology, 2) of digital devide between consumers, and 3) the consumer's attitude to changes of their lifestyle which digital convergence could result in. The subjects were thousand male and female adults. The data were collected from a survey conducted by Embrain, a research firm in Seoul, in the period of June 1st, 2007 ${\sim}$ June 10th, 2007. The results show: 1. Most subjects have computers, their Internet use is their general life, and they have lots of exposure opportunities to digital information. They positively and actively use information technology. 2. Between male and female subjects, and between old and young generation there is a significant digital gap. But the gap between regional areas is statistically not significant. 3. The subject's attitude to digital convergence society shows both positive expectation and negative concerns. Concludingly, to embody a desirable digital convergence society, it is necessary to be searched the ways which can decrease the digital gap and policy to share benefit that information technology can give to consumers.

Purpose of this study is to analyze the meaning of the hybrid digital culture and to find out the features of digital fashion shows appearing in the period of the hybrid digital culture as there have been almost no studies on the hybrid cultural values in the fashion shows and on the diachronic socio-cultural viewpoint of fashion show. The characteristics of hybrid digital culture were identified through the analysis of cases, and they were organized into three for this study; 'non-economic creativity', 'interactive communication' and 'transcendence'. Based on these characteristics, the features of hybrid digital cultures in the modern digital fashion shows were classified into the digitalization of presentation form and the acceptance by audience of digitalization using case studies. The features of digital fashion shows which appear through the presentation form in the digital fashion shows are as follows; 'Expansion of presentation media of runway' and 'Destruction of component factors of runway'. The features of digital fashion show in the perspective of audience's acceptance of digitalization are as follows; 'Audience's field experience through the live video', 'Participation by audience in interactive manner' and, 'Immersion in the virtual reality by the audiences'.

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.

After entering the 4th Industrial Revolution, the digital content market, which was only dependent on existing contents supply enterprises, is providing various digital content through the participation of users like YouTube. Accordingly, it activated the digital content market, but it causes a negative influence on the digital content market due to the copyright of the creator and the indiscriminate illegal use and usage of the content. This study researched digital content management technology based on blockchain technology to protect digital content and the copyright of the creator. The suggested technology protects the digital content and the copyright holder and discerns the users and prevents the indiscriminate approach and illegal use of digital content. For the safe management of digital content, hash function applied as the certification technology of blockchain is used to certify the users and manage the digital content and provide integrity and authentication service.

In the recent context of the Fourth Industrial Revolution, there is growing interest in digital transformation and smart factory as a focal point. But, the Aerospace and Defense (A&D) sector has seen limited research on digital transformation, primarily concentrating on digitally-driven areas. The study validates hypotheses pertaining to the factors that facilitate successful digital transformation within the A&D sector and the influence of digital leadership and dynamic capabilities, employing statistical tools like SPSS and AMOS. The comprehensive analysis reveals that, similar to manufacturing industries, digital leadership in A&D companies exerts an influence on successful digital transformation through dynamic capabilities. Furthermore, digital transformation within the A&D sector has a positive impact on firm performance. This paper offers empirical insights into digital transformation within the A&D sector, shedding light on how successful digital transformation can be achieved within the domestic A&D industry.
