Historically, internet is the fastest growing media together with the ICT development and the key of the development is contents. Digital contents indicate information which covers voice, DB, game, publications and music etc. and the areas have been creating new technology business opportunities. The value chain of digital contents consists of production, collection, processing, services, connection and navigation and is expected to be reorganized around business players of production and distribution areas. This paper presents on those changes occurring in business environment and examples of business models, and further provides industries and academias with technology commercialization strategies.

The proposed new UCI syntax is compatible with the existing identifier and defines fixed length in such cases as printable ID, bar code and QR code which may entail better usage of identifier itself. For the compatibility, the identifiable metadata "key" is used for the existing UCI identifier and "UCI" element of metadata is defined for the new UCI identifier. The new UCI identifier plays roles of the resolution service and representation, and the old UCI identifier plays a role of internal DB management. Also, the object code has two types, meaningless and meaningful. The meaningful object code type can be used according the content classification standards in various field as comics, games, advertisement etc. The standardization activities can be supported by the root agency of UCI.

How can new media devices and networks provide an effective response to the world's growing sector of cultural and historically-minded travelers? This study emerged from the question of how mobile handsets can change the nature of cultural and historical tourism in ubiquitous city environments. As wireless network and mobile IT have rapidly developed, it becomes possible to deliver cultural and historical information on the site through mobile handset as a tour guidance system. The paper describes the development of a new type of mobile tourism platform for site-specific cultural and historical information. The central objective of the project was to organize this cultural and historical walking tour around the mobile handset and its unique advantages (i.e. portability, multi-media capacity, access to wireless internet, and location-awareness potential) and then integrate the tour with a historical story and role-playing game that would deepen the mobile user's interest in the sites being visited, and enhance his or her overall experience of the area. The project was based on twelve locations that were culturally and historically significant to Korean War era in Busan. After the mobile tour game prototype was developed for this route, it was evaluated at the 10th PIFF (Pusan International Film Festival). After use test, some new strategies for developing mobile "edutainment content" to deliver cultural historical contents of the location were discussed. Combining 'edutainment' with a cultural and historical mobile walking tour brings a new dimension to existing approaches of the tourism and mobile content industry.

The purpose of this study is to examine trends and achievements of domestic gamification studies and to suggest further research directions. For this purpose, I collect references in domestic gamification and then analyze them through a systematic literature review. Through search DB, 131 references were collected, the references were analyzed by year, purpose, research type, research methods, and research results. The results showed that the amount of gamification research has increased steadily, and academic discussion in the non-game context has increased sharply since 2015. The results of analysis by research purpose showed that the most research was conducted to evaluate the effectiveness of the strategy, program, and design of gamification. The results of research type showed solution, evaluation, position paper, and validation study in that order. In terms of research methods, literature research was the most common, followed by quantitative, qualitative and mixed research. In the analysis of 45 papers that reported the research results, it was found that there were 21 articles about psychological effects, 17 articles about behavioral effects, and 7 articles about psychological and behavioral effects. Further research directions are suggested based on the review results.

The interest in the service of 3D mobile contents becomes larger due to the technological advance of production and services of mobile contents and the appearance of the exclusive mobile phone for 3D game. Therefore, the researches about the efficient mobile services of large 3D contents are wanted in the circumstances of the narrow bandwidth and the burden of the connection charge of wireless mobile communications. In this paper, we suggest a strategy of caching for looking up and downloading the 3D marine characters efficiently and a system model for mobile service of 3D marine characters. The suggested system is designed for serving efficiently the high-quality 3D characters through the wireless mobile communications using the database on the 3D marine objects of cyber aquarium constructed for the services through the wired internet.

The object of this study is to find ways of a creation and an usage of cultural contents, based on the survey of the culture archetype facts, the culture elements and the narrative structure of 'Geotagi folk tale'. This story takes its place as our cultural archetype, because of its perfect narrative structure and the myth-like features in the story line. Additionally, various cultural elements implied in the text have the world wide universality as well as the unique traditional characters of Korea. Thus, for above reason, 'Geotagi folk tale' can be helpful in creating the new cultural contents. In creating and using the cultural contents of 'Geotagi folk tale', the first way is to build up the Digital contents including the data base of the original text and others, and the creation of graphics. The second way is to create the story bank utilizing hypertext. The third way is to make flash animations or games concerning the folk tale. and the fourth way is to to develop the symbols of the folk tale as animation characters.

In this paper, we propose a stochastic model for sentence speech understanding using dictionary and thesaurus. The proposed model extracts words from an input speech or text into a sentence. A computer is sellected category of dictionary database compared the word extracting from the input sentence calculating a probability value to the compare results from stochastic model. At this time, computer read out upper dictionary information from the upper dictionary searching and extracting word compared input sentence caluclating value to the compare results from stochastic model. We compare adding the first and second probability value from the dictionary searching and the upper dictionary searching with threshold probability that we measure the sentence understanding rate. We evaluated the performance of the sentence speech understanding system by applying twenty questions game. As the experiment results, we got sentence speech understanding accuracy of 79.8%. In this case, probability ($\alpha$) of high level word is 0.9 and threshold probability ($\beta$) is 0.38.
