This study aims to investigate cultural contents planning model by 'The Relation-Approach'. For this, I established conceptual framework of cultural contents, and suggested the General Model of Cultural Sentence Contents Planning: Concept Planning Model(CPM), Signifier Development & Choice Planning Model(SDCPM), Signifier Arrangement Planning Model(SAPM). The importance of culture is found in the importance of perceiving culture derived from the perception of importance of life. As culture is represented way of life constituted in the order of life, perceiving culture is regarded as perception of life in the view of that of cultural contents. Thus, cultural contents planning has not only its necessity and importance but also the meaning of existence in the aspect of being situated at the healthy order of life. Accordingly, A Study on the Cultural Contents Planning Model has usefulness in theory and practice, further more the possibility of attempting for the legitimacy and value contribution to the study of this realm will be accomplished.

This study was conducted for the purpose of analyzing the differences in academic presence and achievement according to the types of e-learning contents development. Content development types were divided into HTML5-based contents, which is interactive contents, and Flash-based contents, which is video presenting type. One group at G high school located in B region learned with HTML5-based contents, and the other group learned with Flash-based contents, and then conducted a survey on the presence and an achievement evaluation. Presence was analyzed through a paired t-test, and the difference in academic achievement was measured through analysis of covariance. As a result of the study, it was found that HTML5-based contents had high levels of presence and academic achievement. Based on the results of the study, the development direction of e-learning contents to be developed in the future was discussed.

This study examines the application of data visualization technology using a clustered data algorithm called 'Tamed Cloud' to virtual spaces and seeks the possibility of implementing it in various types of realistic exhibition contents. To this end, we first attempt to classify virtual reality (VR) exhibition contents starting with COVID-19, and summarize technologies applied. Also, various realistic exhibition contents provide visitors with an opportunity to appreciate the artworks through online and virtual exhibitions. In this trend, virtual reality and augmented reality (AR) technologies have been introduced, allowing visitors to enjoy the artwork more immersively, and the possibility of realistic exhibition content with interaction between the artwork and the user is also being demonstrated. Based on this background, this study examines the history of exhibition contents by dividing them before and after the advent of virtual reality technology, and examines how the clustered algorithm technology called Tamed Cloud was applied to virtual space and implemented as a realistic exhibition content in <70mK> project. By synthesizing all of this, we propose a convergence method of data visualization, virtual reality, and realistic content, and propose it as a new alternative to realistic exhibition content in virtual space.

Technical treatments of image contents on the web include the copy protection method such as the image capture protection technology and the traitor tracing method to detect unauthorized duplications through watermarking insertion or feature information technology. However, these two methods have their own weaknesses. The image capture protection method is unable to protect illegal captures when the URLs of image sources are exposed. The traitor tracing method is fundamentally unable to protect illegal captures due to its post-treatment method. Besides, the weakness of using the copyright information display technology involves easy removal of copyright information from copyrighted contents. This paper suggests a model of the web image contents protection system which makes it hard to separate copyright information from web image contents and allows image contents to be shown only in the authorized websites.

As ubiquitous technology has been developed and has come into everyday life, it has been integrated to tourism information service. However, each regional government develops ubiquitous tourism information service independently without successful example or standard. Therefore, this paper aims to analyze existing cases of domestic ubiquitous tourism information service as a foundation research to establish standard and effective development strategy for accelerating ubiquitous tourism information service in the future. First, ubiquitous technology trend which can be adapted to tourism information service was reviewed by secondary research. Second, representative cases of ubiquitous tourism information service were collected and analyzed in four aspects such as adapted ubiquitous technology, adapted device, service content and type of content. Finally, overall development strategy of ubiquitous tourism information service was discussed based on the analysis result. This paper contributes to get an outline of present conditions and problems of existing ubiquitous tourism information service, suggest overall development direction for ubiquitous tourism information service and point out necessity of the standard and unified plan for nationwide development and management.

IPTV technology for providing multimedia content with high-speed is the network which combines existing network, multimedia and internet technology etc. But internet, broadcasting and web technologies which is now being used is not optimized to IPTV because the security problem between user who gets content service through mobile units and content server is not guaranteed. This paper proposes user certification mechanism between mobile device and content server to receive the service which the user for the content chooses by mobile device safely. The proposed mechanism uses the random number which user creates and certification token for preventing illegal user who uses other's service that already paid. Also the proposed protocol encrypts the delicate data like user's information or profile using shared-key between java card attached on user's mobile device and grant sewer and then prevents reply attack which happens often in wireless section and man-in-the-middle attack by MAC.

The importance of emotional intelligence education in the development of children's augmented reality education content is overlooked. Therefore, in-depth research is needed to develop children's emotional intelligence. This study was conducted through theoretical consideration and case analysis. The proposal of this paper is that the augmented reality type for children aged 2 to 7 is suitable for indoor activities with marking recognition technology. To promote an understanding of emotions, a large screen is selected, and emoticon dolls or emoticon books are recommended for learning content. Children aged 7 to 11 are suitable for indoor activities of non-marker recognition technology, and can induce emotional control and emotional recognition through active manipulation. For the learning content, "3D art teaching content" and "Online Classic Musical" are recommended. Children after the age of 11 are suitable for non-marker recognition technology outdoor activities and improve each element of emotional intelligence through interaction with nature and society. For the learning content, 'Forest Play Activity through Art' and 'EQ Theater Play' are recommended. Through this paper, we intend to promote the development of children's augmented reality emotional intelligence education.

Due to the development of online media platforms and the COVID-19 incident, the mass production and consumption of digital video content are rapidly increasing. In order to select digital video content, users grasp it in a short time through thumbnails and teaser videos, and select and watch digital video content that suits them. It is very inconvenient to check all digital video contents produced around the world one by one and manually edit teaser videos for users to choose from. In this paper, keyframes are extracted based on YCbCr color models to automatically generate teaser videos, and keyframes extracted through clustering are optimized. Finally, we present a method of producing a teaser video to help users check digital video content by connecting the finally extracted keyframes.

Science and technology contents (research papers, patents, reports) are the most common reference material for researchers involved in research and development in the fields of science and technology. Based on various search elements (title, abstract, keyword, year of publication, name of journal, name of author, publisher, etc.), many services are available for users to search science and technology contents and bibliographic information owned by libraries. Authority data on organization name can be useful as an element for author identification and as an element to search for results produced by specific organizations. However, organization name is not taken into account by current search services for domestic academic information and bibliographic records. This study analyzes organization name data contained in the metadata of science and technology contents, which are the basis of the establishment of authority data, and proposes a method and system based on string containment and exact string matching.
