Recently, the capability of efficient access to the desired video content is of growing importance because more digital video data are available at an increasing rate. A video summary abstracting the gist from the entirety enables the efficient browsing as well as the fast skimming of the video contents. In this paper, we discuss a novel dynamic summarization method based on the detection of highlights which represent semantically significant content and the description scheme (DS) proposed to MPEG-7 aiming to provide summary description. The summary DS proposed to MPEG-7 allows for efficient navigation and browsing to the contents of interest through the functionalities of multi-level highlights, hierarchical browsing and user-customized summarization. In this paper, we also show the validation and the usefulness of the methodology for dynamic summarization and the summary DS in real applications with soccer video sequences.

This study as an exploratory study, investigates personal cloud service use which has been developed and distributed rapidly. Focusing on the user's characteristics and use behaviors, the influences of connected uses of platform and contents are empirically figured out. The results show that the contents which need small-data capacity like pictures and musics have been used very frequently in a cloud service. Second, 'platform-connected use' has been found out as the most influential factor in cloud service. SNS, e-mail, and personal innovativeness are also proved as significant factors. As a leading study analyzing theoretically the personal cloud service, it implies that it is necessary to consider the user's characteristics and use behaviors in developing cloud service in the market and making policy for promoting relevant industry.

In this paper, we propose a motion recognition system for identification and interaction with simulator used in the realistic biathlon simulator. The proposed system tried to improve the motions data which is obstructed by the obstacles or overlapping joints and the motion due to the fast motion in the process of recognizing the various motion patterns in the biathlon. In this paper, we constructed a multi-camera motion recognition system based on IoT devices, and then we applied a skeletal area interpolation method for normal motion identification. We designed a system that can increase the recognition rate of motion from the biathlon. The proposed system can be applied to the analysis of snow sports motion and it will be used to develop realistic biathlon simulator system.

This study aims to suggest more efficient ways of teaching English more related to but distinct from major English, based on the needs and awareness of the students of English Education Department. For this, interviews and surveys have been carried out targeting some English Education majors. The results show that the satisfaction level of students is relatively low, marking around the score '3'. While the satisfaction level about classroom environment including the multi-media equipment, and professors' teaching ability, quality and methods is higher compared with other factors, the improvement of English skills and interest-causing levels are lower on average. Besides, this study also includes the surveys on the needs of students for various teaching programs, differentiated classes and qualified instructors. Based on the results, this study makes three suggestions as follows; (1) the opening of some specific English classes for English-education majors (2) the development of English-conversation classes related to English-education majors (3) the development of communication-centered English reading based on English literature.

Based on the basic concepts and roles of the Science Museum, the research and development of the "Sound Light" interaction exhibition contents and experience exhibition space aimed at providing the exhibition, education and experience of scientific principle directly related to daily life will be implemented in the "Sound Light" exhibition space of the Gwangju National Science Museum. The scope of the research is to define the conditions and elements of the museum's hands-on exhibition by examining the case and status of the existing science museum's experience-type content prior research, and research and development of experience-type exhibition scenarios and contents for children based on them. The results of this research and development content are firstly developed with the theme of light and sound as interactive hologram experience content. Second, by multi-faceted media facade through projection mapping by multiple projectors, visual wide and spectacular screen composition and animation are realized. Third, visitors-oriented exhibitions and experiences that can interact with visitors by moving various colors and sounds together. Finally, interactive content is provided through hologram interfaces through hologram screens to encourage active participation of many visitors in viewing rather than simply delivering exhibition information and to promote revisiting the exhibition. Through a series of studies, it was possible to research and develop contents and experience exhibition spaces with theme park characteristics, which are the trend of science museums.

A multi-view display is regarded as the most practical technology to provide a three-dimensional effect to a viewer because it can provide an appropriate viewpoint according to the observer's position. But, most multi-view displays with flat shapes have a disadvantage in that a viewer watches 3D images only within a limited front viewing angle. In this paper, we proposed a spherical display using a ball lens with spherical symmetry that provides perfect parallax by extending the viewing zone to 360 degrees. In the proposed system, each projection lens is designed to be packaged into a small modular array, and the module array is arranged in a spherical shape around a ball lens to provide vertical and horizontal parallax. Through the applied optical module, the image is formed in the center of the ball lens, and 3D contents are clearly imaged with the size of about 0.65 times the diameter of the ball lens when the viewer watches them within the viewing window. Therefore, the feasibility of a 360-degree full parallax display that overcomes the spherical aberration of a ball lens and provides a wide field of view is confirmed experimentally.

The purpose of this study was to examine what kind of images were presented on movie stars in the newspaper. For the purpose, we classified the time period according to the movie industry and media trend, selected representative stars by period, and collected 798 related articles reported in newspapers. As a result of analyzing the reporting trend, domestic and foreign topics, news format, and gender difference in collected movie star articles, it was found that the image of movie stars reproduced in newspaper articles had mostly neutral images that do not represent specific gender. Since the 2000s, news coverage was changed to reproduce various images rather than being fixed to particular images, and the subject of report became more diversified through comparison of domestic and foreign topics. In addition, articles in the form of book review decreased and the interview-type articles increased in number, and in the case of male movie stars, the proportion of articles based on works was high in comparison to female movie stars. This study has significance in that it explored the changes in the process of reproducing star images diachronically from the initial stage of stars to the modern times. And it is hoped that this study will serve as basic data for the follow-up studies on the process of reproducing various images in the multi-media era.

Unlike in the past, a new paradigm has been presented which the use of records is much more important than the preservation of those in the present. It will be necessary for users to signalizes the value of records and to make themselves easily accessible to records in order that records should be more effectively used. To meet the needs of the times, it is the very 'Contents' that starts to attract public attention. National Archives in England produces and provides contents utilizing multi-media by using digital technology on various sorts of archives which England has. In addition to England, Asian Historical Records center in Japan in Japan makes Archival Contents Service reflecting users' needs and continues to update the latest contents. What is more, National Archives of Korea has recently promoted the introduction of digital archive by the change of archival paradigm in records management, and it is giving an impetus to the development of contents in the digital archive. In fact, it is crucial to keep as many contents as possible and to give service to public, but it will not be possible to get positive response from public and to offer much higher level of archival information service until the quality of contents is highly improved. Accordingly, this manuscript analyzed the feature and type of contents which National Archives of Korea provides with cases of both TNA in England and Asian Historical Records center in Japan, each of which has different characteristics. Also, it dealt with several methods of the usage of contents in those organizations. Furthermore, this study explained what kind of contents and feedback are given to users. Moreover, it divided the components of contents of three institutions as mentioned into three by information provided and evaluated the quality of contents by establishing the details of contents. In addition, there were implications for archives with regard to reference for building contents.
