This study was carried out to investigate the compositions of free sugars, lipids, and nonvolatile organic acids in parts of omija. The major components of free sugars in each part of omija were fructose and glucose. The contents of those were similar in fruits and endocarps, however, the content of glucose was 1.5 times as much as that of fructose in seeds. The content of lipids in endocarps was 2.4 times as much as that in seeds, and major composition of lipids was neutral lipid. In the contents of nonvolatile organic acids, the content of citric acid that content was 61 to 68% depend on each part of sample was highest among other components, and that of malic acid being 25 to 30% was followed. The contents of nonvolatile organic acids of water extract were 74.5, 55.9, and 69.2% as high as those of original sample in fruits, endocarps, and seeds, respectively. The content of oxalic acid in seeds was lower than that of it in original sample.

In most applications requiring high-confidential images, reversible watermarking is an effective way to ensure the integrity of images. Many watermarking researches which have been adapted to authenticate contents cannot recover the original image after authentication. However, reversible watermarking inserts the watermark signal into digital contents in such a way that the original contents can be restored without any quality loss while preserving visual quality. To detect malicious tampering, this paper presents a new block-based image authentication algorithm using differential histogram-based reversible watermarking. To generate an authentication code, the DCT-based authentication feature from each image block is extracted and combined with user-specific code. Then, the authentication code is embedded into image itself with reversible watermarking. The image can be authenticated by comparing the extracted code and the newly generated code and restored into the original image. Through experiments using multiple images, we prove that the presented algorithm has achieved over 97% authentication rate with high visual quality and complete reversibility.

The digital contents industry already heads toward the OSMU(One Source Multi Use) method of media. In case the success of the original novel recreates to a movie, the success of a movie is again noticed with the original novel. For this reason, a novel and movie are open at the same time, In this paper, we analyze through the case study of three fantasy films having the narrative structure of the germane myth : The Lord of The Rings, Harry Potter, The Chronicles Of Narnia based on the analysis basis : Hero's Journey 12 steps by J. Campbell, The analysis of scenes of each film visualizing the narrative structure of a novel can be used as the basic materials in the process of visualizing the scale of the original and message of a writer, we consequently believe that these analysis will be able to be applied the appropriate visual techniques (the special effect, the scene tractions, and etc.)in visualization of films.

This study focused on whether the existence and type of originals have any effects on box-office performance of the movie. Cultural products have characteristics of experience goods of which consumers hardly know the value of the products before they actually experience the products. To reduce the uncertainty, movie producers may want to use existing contents already made for other type of cultural products, which is generally called of One Source Multi Use. Using 381 Korean box-office data during January 2010 and September 2012, this study found that, first, the existence of original affects positively the movie's box office performance, second, the fiction based original has a positive effect on the movie's box office performance while cartoon and movie/TV based originals do not, and third, the movie type(commercial movie) positively moderates the relationship between fiction based original and movie performance. This study showed that box-office performance is not only affected by the characteristics of the movie itself, but also affected by other conditions including the use of existing originals created for other purposes.

In Korea the musical was granted very close an art however recently it is rapidly take the position a new trend of the mass culture industry with some of promoted lifestyle due to increased income and with spreading consumer culture of well-being. This study is to consider the musical as a way of OMSU to observe how to produce the musical the with the original one that recorded as the best animation program with highly broadcasting rate as it is broadcasted on TV. It is belongs to a category of musical or a performance, has a good feature of children's program with arranging the broadcasting. Through this study, developing performance art to OSMU, it wishes to utilize people that produce the performance applying the contents of animations and cartoons, to make value added This study is for presenting an effective way of OSMU, with studying and researching the production process of the musical . The original source the cartoon and animation is transferred to a musical with a technical feature of digital audio-visual, with characterizing to an attractive musical characters from the original characters, and with humorize twisted story structure based on the basic storyline.

20 fossil sites of numerous fossil sites in Korea have been designated as Natural Monument for protection and conservation. Many of the sites which is located at the coastal area have been gradually disfigured by natural weathering, erosion and human activity. Thus the conservation of the original form and the documentation for the original figure are necessary. In this study, we applied 3D digital documentation to Natural Monument No. 394, Haenam Uhangri dinosaur, pterosaur, and bird footprint fossil site, for maintaining the original form of the dinosaur footprints. We were able to obtain the 3D digital data on two dinosaur footprint sites, a high resolution distributional map, and more accurate digital data of the dinosaur footprints applied the rendering method by ambient occlusion. 3D digital data on the dinosaur footprints is worth for the conservation and research data, moreover content for applying to the various fields such as to make 3D brochure, interactive contents, and so on.

As an art, Korean dance is a history, a tradition, and a continuing activity of consciousness. It is a present and future activity in the past that will continue the identity of Korean people. So storytelling is not just a description of the historical background, but of eternity that is being recreated. From this study, the inquiry of artistic beauty of Korean traditional dance is questioning the original essence and value of 'storytelling' through old tradition and historical art. If the study of the Korean dance among them was a study of the theorists for the aesthetic essence or the ideological system, the point of view of the storytelling of the Korean dance is that the public understanding about the core structure and reason of Korean dance and the study of the humanistic value It reminded me of a desperate attitude. The meaning of this study is to verify the usefulness of storytelling as a way to construct various contents of Korean dance in conceptual definition of storytelling. In the symbolic meaning of Korean dance, Cheoyongmu text formed the deep meaning network of the original art beyond the linguistic narrative structure and suggested the importance of storytelling development as DB of original contents.

The diffusion of OTT service has brought the fundamental changes in the value chain of the existing media industry. OTT service based on the public Internet has increased the number of subscribers by using dominant marketing capability, making the pay TV platform player's ability to connecting users powerless. This study examined the changes in the media market and pay TV industry in the USA due to the diffusion of OTT service and analyzed the changing strategies of media firms. The number subscribers of the expensive pay TV service in the USA has diminished, experiencing cord cutting and cord shaving due the diffusion of OTT. OTT players are changing the media market, showing the dramatic excellence in making original contents and distributing the newly released movies. Examination of the recent merger and acquisition cases of media firms tells that the investment in making original contents has increased in order to have the competitiveness in OTT business. The future media industry will be rapidly reshaped mainly based OTT service and strategic judgement is important to maintain the competitiveness of all media firms in the existing value chain of media industry.

Most watermarking schemes for video contents protection have been studied to increase watermark's robustness and invisibility against such compressions and many kinds of signal processing after embedding copyright information to the original contents. This paper proposes an active watermarking that infect watermark to contents in the video decoding process using embedded infectious watermark and control signals from a video encoder side. To achieve this algorithm, we design a kernel based watermarking in video encoder side that is possible to recover the original contents and watermark in watermark detection procedure perfectly. And then, by reversible de-watermarking in video decoder side, we design the active watermark infection method using detected watermark and control signal. This means that our system can provide secure re-distributions of video contents without any quality degration and watermark bit error against transcoding or re-encoding processing. By experimental results, we confirmed that the embedded watermark was infected by video contents and codec perfectly without any declines of compression ratio and video quality.

The purpose of this study is to analyze the success and failure of the movie made by the original game by comparing the box office environment of the movie made by the original game and to derive the necessary elements to make a good original movie. The specific analytical content studied the specific successes and failure factors of the remake of the game with , , and . Analyzes of the research show that the audience can be divided into game fan and non - game fans, and how to reflect the expectation on both sides of the movie is an important factor in making the movie. Also, games of different styles and genres from other themes can not be created in the same way as remixing movies, but flexible diversity and management are needed. Unconditional scenarios of games or game switching of movies can not be popular among the public, and it is very important to analyze specific target audiences.
