An educational application (App) called 'Children's Food Avatar' was developed in this study by using a food DB of nutrition and functionality from Rural Development Administration (RDA) as a smart-learning mobile device for elementary school students. This App was designed for the development of children's desirable dietary habits through an on-line activity of food choices for a meal from food DB of RDA provided as Green Water Mill guide. A customized avatar system was introduced as an element of fun and interactive animation for children which provides nutritional evaluation of selected foods by changing its appearance, facial look, and speech balloon, and consequently providing chances of correcting their food choices for balanced diet. In addition, nutrition information menu was included in the App to help children understand various nutrients, their function and healthy dietary life. When the App was applied to 54 elementary school students for a week in November, 2012, significant increases in the levels of knowledge, attitude and behavior in their diet were observed compared with those of the control group (p < 0.05, 0.01). Both elementary students and teachers showed high levels of satisfaction ranging from 4.30 to 4.89 for the App, therefore, it could be widely used for the dietary education for elementary school students as a smart-learning device.

A change of social environment based on digital information technology has decreased the disparity of regional cultures by exchanging & consuming contemporary information & culture freely. After 1995, when local autonomous entity system was established, the local autonomous bodies competed with one another in developing the regional society with its' own resources, human powers & cultures, independently of the central government. In the competitive system, a local government is getting itself distinguished from each other in the cultural & regional properties, and brands the region with its unique events, public relations(PR) & development strategies. The environment for advertisement has changed rapidly under the spontaneous system of regional brand and competition, which means the changes of creative standard in the field of advertisement. An in-depth advertising creativity with induced impression & trust is one of the most important aspects of the advertisement to become persuasive to the public effectively. This demand has had public advertisements changed rapidly and the change of regional system's advertisements has started already. This study focuses on analyzing the status of Local Government's commercials on TV, and presenting an effective method for improving it.

One of the critical themes in the language acquisition is its exposure to linguistic environments. Linguistic environments, which interact with infants, include not only human beings such as its parents but also artificially crafted linguistic media as their functioning elements. An infant learns a language by exploring these extensive language environments around it. Based on such large linguistic data exposure, we propose a machine learning based method on the cognitive mechanism that simulate flexibly and appropriately infant's language learning. The infant's initial stage of language learning comes with sentence learning and creation, which can be simulated by exposing it to a language corpus. The core of the simulation is a memory-based learning model which has language hypernetwork structure. The language hypernetwork simulates developmental and progressive language learning using the structure of new data stream through making it representing of high level connection between language components possible. In this paper, we simulates an infant's gradual and developmental learning progress by training language hypernetwork gradually using 32,744 sentences extracted from video scripts of commercial animation movies for children.

Having a virtual talking face along with a virtual body increases immersion in VR applications. As virtual reality (VR) techniques develop, various applications are increasing including multi-user social networking and education applications that involve talking avatars. Due to a lack of sensory information for full face and body motion capture in consumer-grade VR, most VR applications do not show a synced talking face and body. We propose a novel method, targeted for VR applications, for talking face synced with audio with an upper-body inverse kinematics. Our system presents a mirrored avatar of a user himself in single-user applications. We implement the mirroring in a single user environment and by visualizing a synced conversational partner in multi-user environment. We found that a realistic talking face avatar is more influential than an un-synced talking avatar or an invisible avatar.

The techniques of implementing 3D movie have been developed by stereoscopic representation methods of the scene based on human visual experience. Recently, though various novel approaches for stereo movies are proposed to produce realistic 3D image, more study have to be done for compensating keystone distortion which is generated by moving virtual camera. In this paper we propose a novel production technique which minimizes keystone distortion based on analyzing pixel distance, and is easily implemented on popular graphics environment. First, in graphics environment we categorize each objects as individual layers, and extract image data to produce 3D image. The comparison between each animation sequences from proposed and conventional production methods shows that our production technique well compensate the distortion.

Beginning in 1990's, 3D filmmaking reappeared. As almost every job in filmmaking is digitalized, 3D takes advantage of its new software and hardware, and digital friendly customers as well. One reason why Korean cinema should take 3D seriously is that it can resolve the old and tough problem of unemployed human resources in film production. Another reason is the cooperation programs in which universities and 3D companies can join. 3D cinema can create new cinema goers who don't belong the regular viewer. The totally new experience of 3D can bring people to the movie theaters, and this will add up the total movie customers that expand the whole film industry. The newly designed 3D also could take care of piracy of movie file uploading and downloading through internet. 3D cinema would be precious alternative for film industries of Korea.

The facial modeling and animation technology had been studied in computer graphics field. The facial modeling technology is utilized much in virtual reality research purpose of MPEG-4 and so on and movie, advertisement, industry field of game and so on. Therefore, the development of 3D facial model that can do interaction with human is essential to little more realistic interface. We developed realistic and convenient 3D facial modeling system that using a optional facial image only. This system allows easily fitting to optional facial image by using the Korean standard facial model (generic model). So it generates intuitively 3D facial model as controling control points elastically after fitting control points on the generic model wire to the optional facial image. We can confirm and modify the 3D facial model by movement, magnify, reduce and turning. We experimented with 30 facial images of $630{\times}630$ sizes to verify usefulness of system that developed.

In this paper, we propose a new composite feature consists of both color and shape information that are suitable for the task of character image retrieval. This approach extracts shape-based information using Zernike moments from Y image in YCbCr color space. Zernike moments can extract shape-based features that are invariant to rotation, translation, and scaling. We also extract color-based information from the DCT coefficients of Cr and Cb image. This approach is good method reflecting human visual property and is suitable for web application such as large image database system and animation because higher retrieval rate has been achieved using only 36 features. In experiment, this method is applied to 3,834 character images. We confirmed that this approach brought about excellent effect by ANMRR(Average of Normalized, Modified Retrieval Rank), which is used in the evaluation measure of MPEG-7 color descriptor and BEP(Bull's Eye Performance), which is used in evaluation measure of shape descriptor in character image retrieval.

Culture contents are connected directly with our lives. Experts who produce culture contents or work at such industry or most of people regardless of age and gender are exposed to media contents like movie, game, animation, broadcasting and advertising. There are a number of users who use smart phones and smart pads which can view such media contents. The era of smart device which people easily surf, watch, and produce media contents will be opened. Therefore, the efficient curriculum for producing more touchable media contents should be developed continuously. Most of people recognize the necessity of educations to enhance creativity at university education. This paper intended to research the method of roles curriculum of university produce culture contents which stimulate emotion, creative and show new technology. This paper suggests academic curriculum for department of culture and contents based on the basics, even though new media device emerges the proper talents can be fostered.

The purpose of this paper is to establish an emotional expression factors of digital eye contents that can be applied to digital environments. The emotion which can be applied to the smart doll is derived and we suggest guidelines for expressive factors of each emotion. For this paper, first, we research the concepts and characteristics of emotional expression are shown in eyes by the publications, animation and actual video. Second, we identified six emotions -Happy, Angry, Sad, Relaxed, Sexy, Pure- and extracted the emotional expression factors. Third, we analyzed the extracted factors to establish guideline for emotional expression of digital eyes. As a result, this study found that the factors to distinguish and represent each emotion are classified four categories as eye shape, gaze, iris size and effect. These can be used as a way to enhance emotional communication effects such as digital contents including animations, robots and smart toys.
