In the VnR (Virtual and Real Worlds) of recent virtual reality convergence, the modelling of realistic human face is focused on the facial appearance such as the shape of facial parts and muscle movement. However, the facial changing parameters caused by environmental factors beyond the facial appearance factors can be regarded as important ones in terms of effectively representing virtual avatar. Therefore, this study evaluates user's visual feeling response according to the opacity variation of eye reflection of virtual avatar which is considered as a new parameter for reprenting realistic avatar. Experimental result showed that more clear eye reflection induced more realistic visual feeling of subjects. This result can be regarded as a basis for designing realistic virtual avatar by supporting a new visual realistic representing factor (eye reflection) and its degree of representation (reflectance ratio).

The discussion was started from the question about how literary linguistic expressions are reproduced in the movies. This study focuses on the cinematized version of Jelinek's "Die Klavierspielerin", the by Michael Haneke. and looking for cinematization of literary works and these aesthetic values. The original delicately describes the life of Erika who has been living under the supervision and control by her mother. The topic of the is the conflict between the controlling mother and the desires of the heroin Erika who has been living under the suppression. The world of suppression symbolized by her mother is described as closed and dark space while the world of Erika and her desires, represented by Walter is described as open and bright space. The life of Erika living under control symbolized by prison-like double doors, iron-barred window, darkness and shadow is abnormally distorted. Even the piano that must be the center of her life as a pianist is also one of the symbols of dark world of suppression.

As the very important artistic elements expressing a visual image, the color has been increasing the power of expression. But the relationship between the remarkable peculiarity of colors in accordance with other artistic elements inside the picture plane makes difficult to express an effective expression of color. In the adaptation of color as well as artistic style between & by W. Disney co. is very different each other in the manner of expression. By revealing the difference of the practical use of color and it's principle of those two works, I want to formulate a suitable use of color. In this paper, focus on how to active application of color in relationship between other artistic element and expressive peculiar of color. A right is not only the dominant component in color, but contrast also. A contrast is the most considerable element for modeling order. To emphasize expressive peculiar of color, an artist control artistic element properly and can make expressive energy of brightness & shape.

In domestic game market, the video game market is getting smaller and also decreasing funds and high level developers. So we need the software that can help us to make more realistic and high quality contents by non-expert developer in poor environments. In this paper, we selected global studio's animations which were scored good evaluation by public and critics as a well-made emotional expression that can convey the emotion properly. We selected movements that express emotions from the animation scripts by using Ekman's 6 basic emotions and Greimas' dynamic predicate, and then we had analyzed and categorized with the data. We also analyzed the movements for which data we needed to create specific movements to express emotions by using 'Animation Layer' that used in Unity's blending process. And suggest concept of the program that to create the emotional expression movements by using those analyzed data.

Recent studies have investigated anger or anger-related problems in adolescents from various perspectives. However, understanding of anger expression types or the role of mediating variables in relation to anger and anger expressions have been disregarded. The purpose of this research was to understand the relationships between adolescents' anger, problem solving ability, and three types of anger expressions (anger-in, anger-out, anger-control) and to focus on the mediator function of problem-solving ability. Participants comprised 596 adolescents (283 males and 313 females). Anger was significantly related to all three types of anger expressions. Adolescents who showed high anger levels tended to indicate high anger-in and anger-out expressions but low anger-control expression, while controlling for age and gender. The findings also provided evidence for the mediator role of problem-solving ability on the relationship between anger and anger-control expression. From the results of this study suggestions and limitations were also discussed.

B2B registries provide spaces to register and retrieve information which is necessary to support B2B transactions among business partners or potential business partners. Business process specifications are one of important contents in B2B registries, and there is high complexity of representation due to complex and dynamic characteristics of business processes. Also, currently there exist several competing specification frameworks such as ebXML BPSS, WSBPEL, BPMN, and so on. This paper proposes a metadata schema to register business process specifications which are represented by different specification frameworks. The proposed schema has extensibility to register business process specifications which are represented by various different specification frameworks. Also, it extends reuse level from whole business specification processes to their components. To show the usefulness of the proposed schema, this paper demonstrates metadata extraction from business process specifications which are represented by two representative XML-based business process specification languages, ebXML BPSS and WSBPEL.

Computer graphics technology has advanced such that all objects can be represented within a computer display. However, because computer displays have a finite resolution, the variety of objects that can be realistically represented together in the same view is restricted by the difference in their relative size. In addition, objects cannot be rendered according to their physical properties in terms of real length units in current computer graphics technology. To solve these problems, we have defined a method that allows objects to be described using real-world physical property units, such as metric units, in a computer graphics system, and developed a 3D browser based on X3D, which implements the concept of relative proportion properties.

In this paper, the trends for the standardization of the product model was surveyed, and the product model can be used as concrete means to realize the communication of information between the CAD/CAM softwares, which are used for the design and manufacturing of the complex products such as ships. We have proposed the newly developed methodology for the representation and definition of the ship model on a basis of the product model. And also we have studied the product modeling technology for the aspect of an application, and the object-oriented system technology have been surveyed for the system implementation issues. We would like to verify the consistency and correctness of our proposed representation methodology by using the prototype application model, which is applied to design work of ship compartmentation model. For this purpose we have developed the "OO_COMDEF"(which means the Object-Oriented System for the Compartmentation Definition of ship) program that is applied to the compartmentation model which can be considered as a submodel of the general ship models. The results of research work have been proved that the representation methodology for the ship model based on the product model is an efficient and appropriate scheme for the ship model definitions. Consequently, this methodology can be proposed as a fundamental framework for the development of the shipbuilding CAD/CAM system.

This study aims to suggest the amendment method of publishing bulletins for election in accordance with the changed consciousness of voters and the environment of times after examining the expression strategies of a candidate's message through the analysis of publishing bulletins of local election in 2010. Accordingly, it tries to indicate the strategies of publishing bulletins for election more easily and briefly. As to the description of expression strategies, there were a lot of rational descriptions and positive appeals with the perspective of a third person. It shows the awareness that aggressive and negative expression brings about adverse effects. The appeals of the cover slogan in campaign promises were in the sequence of the candidate's character, regional development, and social welfare, and most campaign promises were within the range of ten promises. The most used symbol of candidates was the party which candidates belong to. The main empathized contents include the name of candidates, the experience of candidates, management, political ability, and region. In addition, slogans had the intention to express folksy and intimacy by raising the rates of residents' emergence.

The efficiency of the multiplier largely depends on the representation of finite filed elements such as normal basis, polynomial basis, dual basis, and redundant representation, and so on. In particular, the redundant representation is attractive since it can simply implement squaring and modular reduction. In this paper, we propose an efficient bit-parallel multiplier for GF(2m) defined by an irreducible all-one polynomial using a redundant representation. We modify the well-known multiplication method which was proposed by Karatsuba to improve the efficiency of the proposed bit-parallel multiplier. As a result, the proposed multiplier has a lower space complexity compared to the previously known multipliers using all-one polynomials. On the other hand, its time complexity is similar to the previously proposed ones.
