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.

With the rapid improvement of the internet and information technology, digital contents containing knowledge and information resource is circulated through the internet. A circulation system based on a standardized identifier is required to share this kind of information, generated from seminars and workshops conducted in the area of science and technology and saved in the form of digital video contents. The main objective of this study is on constructing an information circulation system based on the KOI identifier to effectively share the digital video contents produced from seminars and workshops related to the area of science and technology. Furthermore, the overview and status of a standardized identifier, and the functional aspects of the system such as the methods to apply the KOI identification system on the subject and its slides of digital video contents, a digital video contents management system, a centralized identifier management system, and the methods applied for the search of digital video metadata have been suggested to support construction of the information circulation system.

With the rapid growth of information technology and the internet. the physical contents are transformed into digital contents at a fast rate. With the change. accessing the digital contents, toe service methods and the identifier used for the digital contents are not systematic and limited for use. The DOI identifier system used for the URN is also limited to academic journals or magazines and are not adequately applicable for non-academic journal or digital contents. Therefore. we have developed a unique identifier based on the analysis made on the system adopted by foreign digital contents service institutes. two types of academic journals 3 types of non-academic journals owned by KISTI that can be adopted by non-academic journals. The identifier is to be used to design and implement a digital contents service system.

UCI(Universal Content Identifier), a digital content identifier is a identification system based on URN(Uniform Resource Name) for the transparent distribution, efficient search and management of digital contents. Digital contents given a UCI number need metadata for serving a exact contents that users need. However, the only metadata provided by UCI are deficient to represent various information of digital contents, and ontologies which could standardize and define explicitly semantic relations between metadata (provided by UCI) are needed for better representation of information and efficient search and management of digital contents. In this paper, we extended concept-relation between metadata with ontology and designed domain ontology enabling semantic-based search by expanding UCI meta data, and showed the more efficient search and management over the metadata by UCI through various queries.

With the development of modern society, we are all living in a world where information is shared through mass media and environment. Just as there was an identifier for the approach of information in the past analog environment, there is a demand for the continuous development and research of an original identifier for each and every digital contents of the changing digital environment. In order to present the need for standardization of effective construction concerning digital contents, this study examines the identifiers system structure of ISBN and ISSN of the analog environment and URL, URN, URC, which are under the URI system of the digital environment. After analyzing the problems of different URL identifiers construction in each university library's OPAC system, this study presents a standard device of effective identifiers patterns.

Contents Recommender System predicts user's preferences towards contents, and then recommends highly-predicted contents to user. Digital Identifier plays its part in identifying abstract works or digital contents in digital network environment. Digital Identifier could be effectively used in content-based filtering and collaborative filtering that are mainly used in Contents Recommender Systems. Therefore, this paper proposes an improvement of UCI metadata and resolution service for effective use of UCI in massive contents recommender systems. UCI metadata is expanded by adding elements such as abstract, keyword, genre, age, rate and review. Resolution service allows the operation systems to collect user preference for content by including input part of preference in a result page. This paper also designs and implements an improved UCI operation system and shows that the proposed improvement of UCI metadata and resolution service could be used for massive contents recommendation.

The rapidly increasing use of the Internet and advancement of the communication network, the explosive growth of digital contents from personal home pages to professional information service the emerging file exchange service and the development of hacking techniques . these are some of the trends contributing to the spread of illegal reproduction and distribution of digital contents, thus threatening the exclusive copyrights of the creative works that should be legally protected Accordingly, there is urgent need for a digital copyright management system designed to provide centralized management while playing the role of bridge between the copyright owners and users for smooth trading of the rights to digital contents, reliable billing, security measures, and monitoring of illegal use. Therefore, in this study, I examined the requirements of laws and systems for the introduction of the centralized management system to support smooth distribution of digital contents, and also researched on the current status of domestic and international centralized management system for copyrights. Furthermore, 1 tried to provide basic materials for the standardization of digital contents copyright management information through the examination of the essential elements of the centralized digital contents management such as the system for unique identification the standardization for data elements, and the digital rights management (DHM) .

Composite and compact devices equipped with the functionality of digital still image acquisition, such as cellular phones and MP3 players are widely available to common users. In addition, the application of digital still images is becoming common among security and digital recording devices. The amount of still images, that are maintained or shared in personal storage or massive storage provided by various web services, are rapidly increasing. These still images are bound with file names or identifiers that are provided arbitrarily by users or that are generated from device specific naming method. However, those identifiers are vulnerable for unexpected changing or eliminating so that it becomes a problem in still image search or management. In this paper, we propose a method for still image identifier generation that is created from the still image internal information.
