We propose an emotional facial avatar that portrays the user's facial expressions with an emotional emphasis, while achieving visual and behavioral realism. This is achieved by unifying automatic analysis of facial expressions and animation of realistic 3D faces with details such as facial hair and hairstyles. To augment facial appearance according to the user's emotions, we use emotional templates representing typical emotions in an artistic way, which can be easily combined with the skin texture of the 3D face at runtime. Hence, our interface gives the user vision-based control over facial animation of the emotional avatar, easily changing its moods.

A decode-and-forward system with an energy-harvesting relay is analyzed for the case when an arbitrary number of independent interference signals affect the communication at both the relay and the destination nodes. The scenario in which the relay harvests energy from both the source and interference signals using a time switching scheme is analyzed. The analysis is performed for the interference-limited Nakagami-m fading environment, assuming a realistic nonlinearity for the electronic devices. The closed-form outage probability expression for the system with a nonlinear energy harvester is derived. An asymptotic expression valid for the case of a simpler linear harvesting model is also provided. The derived analytical results are corroborated by an independent simulation model. The impacts of the saturation threshold power, the energy-harvesting ratio, and the number and power of the interference signals on the system performance are analyzed.

Painting, as an artistic creation with aesthetic characteristics, is inseparable from "shape". "Modeling" is a subjective way of expressing objects, and "black shape" is not only a way of expression, but also a way of composition. "Black shape" is a way of expressing the overall picture of the creator, and "black shape" extracted from the pattern analysis of black and white gray structure is a powerful means to deeply explore the emotions and thoughts of the painter. How to create the expression of subjective intention in the creation of artificial figure painting and to explore the beauty of picture form and the presentation of formal language in multiple dimensions is always sought by painters. Tang Dynasty political stability, economic and cultural development of unprecedented prosperity, "Toujian Diu" as a representative painting of Tang Dynasty, the figure is plump and realistic, colorful but elegant. It not only represents the aesthetic taste of the Tang Dynasty, but also reflects the overall style of the Tang Dynasty's artificial figure painting. The aim of this paper is to explore the value of "black shape" in "Toughen Diagram" and analyze its multi-component form in depth.

사실성을 미적 특성으로 하는 컴퓨터 그래픽스의 활용은 디지털 애니메이션에 있어서도 이미지와 움직임 묘사의 사실성을 강화하였다. 그러나 디지털 애니메이션의 사실성은 실제를 있는 그대로 모사하지 않고 변형을 통한 물리적 제한의 극복과 상상의 실현이라는 애니메이션의 전통적 미적 의의를 계승하고 있다. 즉, 이처럼 강화되는 사실성 사이에 간헐적으로 삽입되는 카툰적 과장은 현실과 상상의 교차라는 대조와 충돌을 이루어 변증법적 합(合)으로 유희를 창출하게 된다. 즉, 디지털 애니메이션에서 사실적인 표현들과 충돌하는 비합리적 카툰적 변형들의 충돌과 대치로 서로를 보강한다. 사실적인 표현으로 관객이 실제를 마주하듯 몰입하게 하다가도 어느 순간 물리적 제약을 극복하는 행위들은 상상의 실현 내지 정신적 해방감을 준다. 결국 사실적 표현은 현실로써 전제가 되며 카툰적 변형은 그러한 제약을 극복하는 것이 되어 관객에게 유희로 작용한다.

The purpose of this study was to show the analysis system and the expression which is applied to fashion illustration by three major components in visual sign, metaphor and metonymy. The results of this study were as follows : Firstly, metaphor in qualisign of syntactics was revealed as a color such as realistic description, a pattern such as clothing of figure. etc. Metonymy was revealed as a social and cultural background color, a concept pattern. etc. In sinsign of syntactics. metaphor was revealed as a human body, non-human body and metamorphosis human body and metonymy as a human body and non-human body. In legisign of syntactics, the metaphor by perspective was used for a fantasy of space. and the metonymy was revealed as a color perspective representation, etc. The degree of change of texture was revealed as a metaphor and metonymy of gradation. And conventional custom sign was almost revealed in metaphor. Secondly, semantics showed about fashion image as juxtaposition of two similar objects in metaphor and as real description and simplification in metonymy Alternative fashion image in semantics was presented as a object related to fashion image. Conventional symbolic sign was presented as a role to clarify a fashion message in metaphor. Thirdly, the metaphorical and metonymical expression in pragmatics were usually presented as drawing and painting.

Recently, in the fields of fashion, advertisement, film, literature, philosophy, etc., the word, 'Nomad', is being used frequently across the overall society. The contemporary society is actively incorporating "nomadic thinking" as a new social phenomenon across the boundaries of conventional fields. This is not an exception in the field of space design. This study, via the contemporary nomadic thinking, examined the relationship between space design's application possibility as a new trend and flexible space; then categorized the characteristics of flexible space into flexibility, temporariness, changeability, and correlation; and then analyzed expression characteristics of flexible space. As for unrestricted expression of scene, it was recognized that separation of scene and space leads space to meet the needs of surrounding environment and users; formation of changeable space enables uses of space from various perspectives; and combining external factors (energy, media technologies) with space leads space to self-evolution. Space is perceived as an living organism that is flexibly corresponding, via realistic movement and virtual movement, to the indefinite, diversified thinking of the contemporary society. Therefore, this study illuminates that nomadic thinking has significance as basic thinking to predict development and characteristics of design thinking through understanding the contemporary society with the basic thinking system that has been inherent without restrictions of being fixed to the present, past, and future.

The purpose of this study is to analyze the expressional traits and internal meanings of fake design in the 2000s' fashion, based on study of art and design area. For achieving the purpose, this study performed related research works and a demonstrative analysis of fashion collection photographs. The scope of this study is from 2000 to 2009. The results are as follows. Fake design uses trompe-l'oeil which is an art technique related to the meanings of 'deceive or fool the eye'. This eye-deceiving technique has been used for a long time in the art, and particularly noticed as one of techniques of Surrealism. Art works using trompe-l'oeil express familiar and unreasonable world at the same time, and also the fusion of reality and fabrication. Fake design in design area of the 2000s makes people take daily life in unfamiliar way by unusualness and breaking the boundary between real and fake. By fake design, people can enjoy fun and a sense of freedom with amusement rather than unpleasant of being deceived. Fake design in the fashion of the 2000s uses eye-deceiving technique and also focuses on the concept of 'fake'. The expressional traits were categorized as realistic expression, surrealistic expression and fake value expression. The internal meanings were analyzed as breaking boundary between real and fake, rediscover dailiness, new attitude to traditional thinking. In conclusion, fake design in the fashion of the 2000s gives playfulness, fun, feeling of release and will be pursued continually.

Transcriptional modulation of metallothionein (MT) during acute metal exposures (cadmium, copper or zinc) was examined in fry of Hemibarbus mylodon, a threatened fish species in Korean peninsula. Viability of H. mylodon fry was most affected by copper exposure (up to 79% of mortality at 1 ppm for 48 hours) and considerably by cadmium exposure (21 to 54% of mortality). On the other hand, Zn showed the least adverse effect on the viability (0 to 13% of mortality) of this species. Based on the semi-quantitative RT-PCR analysis, the stimulation of MT mRNA in response to metal exposures followed generally in a dose-dependent fashion where cadmium was the most potent inducer for the induction of MT transcripts in fry (up to more than 5-fold) while the lowest response was observed in zinc-exposed group (2-fold at maximum). From the exposure using environmentally realistic doses of cadmium (0 to 0.05 ppm for 24 hours), MT expression at mRNA level was also sensitively modulated toward upregulation up to more than 3-fold as relative to non-exposed control. Results from the present study would be a good basis for understanding the adaptive capacity and stress physiology of this endangered fish species during metal pollution.

We are in the process of the deepening of the informationalized society. Such a phenomenon(of deepening of the informationalized society) means that human being is surrounded by a linguistic or semiological environment instead of realistic experience. And it is concerned with the visual design composed by the visual languages and semiotics of Arts. Because the visual design is a kind of the linguisticsmion using the visual formation. This penomena necessarily brings the expansion of the quatity of information and accompanies the simplification of messages. Therefore when we apply the simplicity resulting from the ideality of KYEORE painting(the folk Art of Korea), it can be cotribute to those who should be in the center of semiological environment more deeply as a source to maximize the effect of communication, which is the conclusion of this study. In sort, the characteristics of our KYEORE painting is the ideal expression. There are found not a few problems such as the depiction of forms, the perspective representation, the chiaroscuro, the expression of material if we evaluate them from the western formative viewpoint. But the depiction of the fact is less direct than the ideal expression itself, is likely to be much complicated, and can be far away from the world of reality. Because it is just the first step for satisfying the ideal images in man. In the composition of KYEORE painting is dominated by the rules nonprescription of time amd place, colloquialism of the meaning, distinction maximization. They are all the compositive characteristics resulting from the ideality. If these characteristics are modulated intelligently to the current thoughts, they will help to build the new visual communication system of Korea which has more direct and fast absorption force.
