Implicit surface model is convenient for modeling objects composed of complicated surfaces such as characters and liquids. Moreover, it can express various forms of surface using a relatively small amount of data. In addition, it can represent both the surface and the volume of objects. Therefore, the modeling technique can be applied efficiently to deformation of objects and 3D animation. However, the existing implicit primitives are parallel to the axis or symmetrical with respect to the axes. Thus it is not easy to use them in modeling objects with various forms of motions. In this paper, we propose an efficient animation method for modeling various poses of characters according to matching with motion capture data by adding the attribute of rotation to metacube which is one of the implicit primitives.

IP address lookup is one of the most important and complex functions in the router. In this paper, we propose an improved technique of LC-trie to increase the performance of IP address lookup in the high performance router. We effectively apply the prefix pruning method, which is used for the compression of the forwarding table in TCAM((Ternary Content Addressable Memory), to the LC-trie. This technique can decrease the number of memory accesses and upgrade the lookup speed. Moreover, through the real forwarding table and the real traffic distribution, we evaluate the performance of our scheme in terms of the lookup time and the number of memory access, comparing with that of the previous LC-trie.

With the fee-based policy starting in 2001, the income statement of the contents providers shows that the contents sales is the number one portion, while the dotcom companies focusing on community sites have difficulties in diversifying business models. To overcome this problem, Freechal, a leader of community sites, employed a fee-based strategy for the first time in 2002, however, this attempt was failed because of a rapid decreasing number of community members. Many Internet companies too much relying on advertisement sales have been trying to turn into the fee-based business model, however, it is difficult for them to make an action plan owing to little research in this field. This paper provides an overview of community sites including their history, business models, and characteristics as well as suggests the implications from a Freechal case.

The incidence of inflammatory bowel disease(IBD) has increased continuously in worldwide, but no cure have been discovered. The etiology of IBD may include various factors such as genetics, epigenetic, environment as well as host immune system. Among the environmental factors of IBD, diet heavily influences gut health, especially non-digestible dietary fiber can have a great impact on selective growth of beneficial gut microbiota called probiotics. Seaweeds have been consumed in Asia countries and are a rich source for dietary fiber. Accumulated data have suggested the possibility of utilizing seaweed derived oligosaccharides as prebiotics to prevent IBD and its recurrence. In this review, seaweed derived oligosaccharides such as fucoidan and laminarin regarding gut health and potential therapeutic tools for IBD will be discussed based on studies conducted in vitro and in vivo models.

The expression of natural backgrounds in a digital clip such as forest, water and sky break new ground and evolve. The process of arriving at a certain background style and designing belongs to the pre-production stage of animation produuction. Due to the advancement of CG technology, the production and consumption of animation has accelerated and so in an effort to reduce production time, the natural background has increasingly becomme normalised. For the distinction in contents, narrative and characters are emphasized in pre-production since it is believed that the background design will simply be a still image. However, there is a need to focus on background design as it is a tool that can effectively emphasize the narrative. This research is an analysis of the background design's role in forest background in productions such as "Alice's Adventures in Wonderland"(1951) and "Princess Mononoke"(1997). It details how appropriate each background forest was for the artist's intent using the 7 types of forest landscapes according to dendrology.

Many companies are practicing contents marketing employing YouTube by not only creating their own YouTube channels and YouTube contents but also collaborating with YouTube creators. Purpose of this study is to figure out how domestic standalone beauty brands that are actively practicing content marketing, are exploiting the YouTube and to suggest design direction for future YouTube content marketing. 'Etude', 'Innisfree', 'Misha', 'The Face Shop' were selected for analyzing the content marketing cases using YouTube. As a result, this study could conclude that if the brand has inadequate number of subscribers, it is better to collaborate with the creators.

Thanks to the advancement of the related technologies and equipment, today's video contents like movies, animations and soap operas are rapidly expanding their expressible cinematic imagination area. In order to fulfill the elevated visual expectations of audiences and realize exciting storytelling and fantastic world, the fusion of different techniques is actively used, and the reality for visual effects and image synthesis is increasing more and more. Accordingly, recent VFX-oriented movies using CG have a much more complicated production process than before. Therefore, the importance of Pre-visualization, aka Pre-vis is becoming bigger in the planning process for sophisticated design. Pre-vis means that the advance visualization for stories or directing ideas in the planning process before starting production of movies or animations. 3D animated Pre-visualization realizing directors' abstract and ambiguous ideas in 3 dimensional environment in advance is, as a powerful means for visual storytelling, briskly used focusing on the VFX film industry on which the present CG is broadly used, and the role of Pre-vis throughout productions has increased compared to the past. The studies, however, on the role and utility of Pre-vis are not enough. Therefore, this study was conducted on the role of Pre-vis used for present VFX movie productions using the examples of 3D animated Pre-visualization production in which the researcher of this study participated. In this study, the role of the Pre-vis that is subdivided presently, is divided into and 3D animatics and their each role is analyzed with the example images. Through this, the characteristics that Pre-vis should have are clarified and the concept of the advantages and utility led by the use of Pre-vis in productions is strengthened. The goal of this study is to induce active uses of Pre-vis throughout productions after forming consensus about the various roles of Pre-vis and their utility.

This study attempted to empirically investigate the difference in the Advertising Acceptance Attitudes of pre-roll advertisements according to the Use Motivation and Use Intensity of YouTube, which act as important factors in using YouTube. For this study, a survey targeted to both male and female university students was conducted, 200 people's data being used for the analysis. First research result was that positive attitude towards advertisement based on the Youtube Use Motivation was higher for the group who pursue narrative identities than the group who habitually use intention and pursue amusement. For avoidance behavior, the group who habitually use intention and pursue amusement was higher than the group who pursue narrative identities. Second, for the positive attitude towards advertisement based on Youtube Use Intensity, the group with higher Use Intensity showed an optimistic attitude relative to the group with lower Use Intensity. However, there was no difference in the avoidance behavior for advertisement. These following results imply that a strategy considering the Use Pattern based on the Use Motivation and Use Intensity of the users is needed in enforcing YouTube pre-roll advertisements.
