The importance of a using the visual media in English education has been increased. By an importance of Characters in English language content, the more effort is needed for a learner to show the English pronunciation and a realistic implementation. In this paper, we tried to review the Syntax-based Educational Contents Authoring System. For the more realistic lip-sync character, 3D character to enhance the efficiency of the education was constructed. We used a chart of the association structure analysis of mouth's shape. we produced an optimized 3D character through a process of a concept, a modeling, a mapping and an animating design. For more effective educational content for 3D character creation, the next research will be continuously a 3d Character added to a hand motion and body motion in order to show an effective communication example.

Diverse disciplines such as information science, computer science, cognitive science, and industrial design, are activity engaged in the website evaluation research efforts. Information scientists emphasize the importance of user-centered and user-friendly website design, which is also easy to use, This idea is based on the understanding that the users and the designers are different set of people. In addition, information scientists consider the practice of maximally incorporating user inputs during the website design to be very important guideline. However, this study is based on a newly emerging population of website users who are also designers. 218 study participants evaluated the websites that they designed in comparison to the websites designed by others. According to the survey data analysis, the study participants considered the content delivery, design simplicity, design consistency, and link access of the websites to be equally important from both users' and designers' perspectives. However, the content organization, rich content, and screen composition were underestimated from the designers' point of view whereas these factors were considered to be important from users' point of view.

The purpose of this study is to classify appropriate content types according to the cyber education contents needed for employees of health and welfare and to develop contents based on specific instructional design strategies for each type. We divided the four types of content into instructor-led type contents, storytelling type contents, practice type contents, and case presentation type contents based on previous research and existing health and welfare cyber education contents. For each content type, a macro design strategies and a micro design strategies were derived, and contents were developed in accordance with the design strategies. Data were collected from 150 employees of health and welfare to analyze learning satisfaction. The average of learning satisfaction was 4.42. The results of this study will provide theoretical background and practical implications for the design and development of cyber education contents in health and welfare areas.

The purpose of this study is 1) to investigate the Web content of online shopping agencies and to see if differences exist in their contents and 2) to suggest strategies for online shopping agencies. For the study, the online shopping agency components of web sites were investigated, which consisted of product, information, and customer service. Each component had sub-categories. In order to analyze the Web content of online shopping agencies, nine agencies were chosen based on the rankings of www.rankey.com and www.100hot.co.kr. The content analysis was conducted from January 5th to the 30th of 2009. The results showed that the basic Web content of online shopping agencies (i.e., product, information, and customer service) was evident on most sites. However, products were similar and effective information and labor-saving functions were sparsely used. Areas where customers actively participated were limited. Therefore, most sites need to reinforce their content by providing a well-articulated product, information, and customer service for shoppers and to differentiate their Web site identities.

We have several kinds of DRM(Digital Rights Management) solutions which protect and control a content based on the cryptography. The current technology of DRM focuses on the content management in the purchaser. It doesn't consider the content management in the other principles like creator, provider, and distributor and doesn't provide the efficient environments of a content distribution. In this paper, we propose a digital content distribution system which processes a content and metadata with electronic copyright management.

Purpose: This study examines the relationship between content characteristics and customer viewing and purchase intention in live-streaming commerce. Research design, data, and methodology: For this purpose, seven independent factors such as entertainment, artistry, storytelling, informativity, interactivity, reliability, and technicality are extracted based on previous literature. The viewing intention and purchase intention are adopted as dependent factors. The role of 'immersion' is investigated as a mediating factor between the independent and dependent factors. Results: The results showed that entertainment, artistry, technicality, and reliability significantly affected immersion, and immersion affected viewing intention and purchase intention. Immersion was found to play a mediating role between content characteristics and consumer viewing and purchase intention. Conclusions: The results indicate that the content characteristics not only attract customers but also affect their immersion, viewing intention, and purchase intention directly or indirectly in the live-streaming commerce sector.

Response surface methodology (RSM) was used for the analysis and optimization of the production process of strawberry Kochujang. Experiments were carried out according to a central composite design, selecting strawberry puree content and red pepper powder content as independent variables and soluble solids content, moisture content, water activity, color characteristics ($L^*-$, $a^*-$, and $b^*$-values) as response variables. The polynomial models developed by RSM were highly effective for describing the relationships between the study factors and the responses. Kochujang containing a higher amount of red pepper powder had a higher soluble solids content; on the contrary, soluble solids content decreased with the increase in the strawberry puree content in the sample. Moisture content increased with increased strawberry puree content but decreased with increased red pepper powder content. Water activity increased with the increase in strawberry puree content in the sample but was less affected by the amount of red pepper powder content. Decreases in $L^*$-values with increasing amount of red pepper powder were noted. $a^*$-values decreased with the increases in red pepper powder content but increased with the increase in strawberry puree content in the Kochujang formulation. $b^*$-values decreased with the increases in red pepper powder content but was less affected by the strawberry puree content. Overall optimization, conducted by overlaying the contour plots under investigation, was able to point out an optimal range of the independent variables within which the six responses were simultaneously optimized. The point chosen as representative of this optimal area corresponded to strawberry puree content=14.36% and red pepper powder content=11.33%, conditions under which the model predicted soluble solids content=$59.31^{\circ}Brix$, moisture content=45.30% (w.b.), water activity=0.758, $L^*$-value=24.81, $a^*$-value=7.250, and $b^*$-value=10.19.

This paper presents statistical models developed to study the influence of key mix design parameters on the properties of lightweight self-consolidating concrete (LWSCC) with expanded shale (ESH) aggregates. Twenty LWSCC mixtures are designed and tested, where responses (properties) are evaluated to analyze influence of mix design parameters and develop the models. Such responses included slump flow diameter, V-funnel flow time, J-ring flow diameter, J-ring height difference, L-box ratio, filling capacity, sieve segregation, unit weight and compressive strength. The developed models are valid for mixes with 0.30-0.40 water-to-binder ratio, high range water reducing admixture of 0.3-1.2 % (by total content of binder) and total binder content of $410-550kg/m^3$. The models are able to identify the influential mix design parameters and their interactions which can be useful to reduce the test protocol needed for proportioning of LWSCCs. Three industrial class ESH-LWSCC mixtures are developed using statistical models and their performance is validated through test results with good agreement. The developed ESH-LWSCC mixtures are able to satisfy the European EFNARC criteria for self-consolidating concrete.
