Character graphic design of TV screen, the major visual element, has become greatly important in its roles to help viewers understand visual information better and to enhance the qualities of the program. This research is to figure our a way of changing and improving the attributes of TV captions and graphics such as fonts, size, and caption speed appropriate to bigger and better qualified TV screen. Based on two Delphi surveys of graphics experts along with the theoretical studies, this article analyzes the relevance of visual perception to various visual elements of TV screen, and proposes a better plan in visual effects for various media under OSMU (One Source Multi Use).

In the meantime, broadcasting CG has gone through the process of dismantling, changing, and distorting, while broadcasting CG in broadcasting programs utilizes the expanded background of 'temporality' and 'formality'. This is to create an audiovisual language that appeals to human synesthesia by expressing the meaning to be conveyed in three dimensions. Broadcast CG goes beyond simple instructional and informational broadcast graphic operation, and increases the pure aesthetic value and sensibility of the video considering readability and formativeness, and through this, the audiovisual information perfection of the broadcast program is derived and acts as a very important factor. Therefore, this paper examines the results of broadcast CG production and utilization methods at existing local broadcasters, and identifies the limitations of local broadcasters' CG production and utilization through case analysis for each broadcast program type. We want to derive a model that is a compromise line. In addition, I would like to suggest a plan that can be applied more actively and practically to local broadcasting programs. In order to solve this problem, this study first examines "Analysis of cases of use of broadcasting CG production in broadcasting programs" and then "more efficient broadcasting CG production techniques by identifying problems in broadcasting CG production methods and utilization of local broadcasters" and how to actively use it". In addition, the results of this study are expected to contribute to the establishment of a new role and practical broadcast CG production model for broadcast graphic designers in charge of broadcast CG production and the technical perspective of broadcast program production by local broadcasters.

This paper presents an automated visualization system, called StyleVisualizer, which checks the coding style of source codes and visualizes the coding style score using facial expression. Our system represents some kinds of facial expressions according to the evaluated score of the code style: A smile face means that the source code follows coding standards correctly. To measure the effectiveness of the StyleVisualizer, some experiments have been conducted on two class students in an applied computer course. In the experiments, we have compared the error ratio for obeying the coding standards when the StyleVisualizer was used or not. According to the experimental results, the error ratio with the StyleVisualizer was reduced above 30% than that without it. We expect that our system can encourage the students to obey the coding standards by providing the feedback of the visualized faces corresponding to their programs, resulting in high readable programs.

This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood(http://ifood.or.kr)', for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were 'Interesting games' for 35.8%, 'How can I cook?' for 17.8%, 'How can I become slim' for 16.4%. This website might be more attractive by providing a 'greater variety of contents in detail', 'more music, motion pictures and images', 'more interesting games'. After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that 'ifood', a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

What is an appropriate length of an article in the mobile era producing new tastes of contents combining computing and mobile communication? Is it still valid to have a lengthy article as high level journalism even in the mobile era? Is there any possibility to have a short article combination to give us readability and the amount of information? This study aims to find some answers to these questions. The length of articles were controlled with a field experiment; from an article of 346 syllables(including spaces between syllables) which does not need finger scrolling on a mobile phone to articles of 633, 1033, 1368 syllables(including spaces between syllables) which frequently appear in newspapers and broadcasting news program. All the main themes were same for 4 articles which have different length. Three hundred and eighty four students viewed one of the 4 articles through mobile phone or newspaper. Each participant checked their preference and evaluated quality on the article, were asked to recall contents of the article. In newspaper group, articles with 346 or 1033 syllables were highly evaluated. Mobile group seemed to prefer articles of 346 or 633 syllables. In conclusion, we need to consider various strategies shortening the length of an article into 346 or 633 syllables as a basic format to meet the neEds of mobile era.
