The Korean animation has enjoyed the brisk formation and establishment of its world-class infra for the last several years without unified titles or concepts, under the name of a national strategic project in the age of digital image. It also enjoys its new evaluation as digital animation that it's one of the greatest money making business in the non-education and frivolous culture and has the closest relations with the modern time. A great portion of popular image media has been taken by animation for the last 30 years. In this paper we propose a motion algorithm using an animation technology. It was developed for education purposed and accessible through the internet. For instance, in Cyber Clam Museum, 1000 gesture contents, the visual processes were used to design a screen with a realistic image and create an animation that makes possible show at 360 and every such transformation as translation, rotation, and scaling can be applied in the image interactively for the convenient and effective viewing.

In this digital information era, utilization of images are essential for various media, and the edge is an important characteristical information of an object in images that includes the size, location, direction and etc. Many domestic and international studies are being conducted in order to detect these edge. Existing edge detection methods include Sobel, Prewitt, Roberts, Laplacian, LoG and etc. which apply fixed weight value. As these existing edge detection methods apply fixed weight mask to the image, edge detection characteristic appears slightly insufficient. Accordingly, in order to supplement these problems, this study used bottom-hat transformation from mathematical morphology and opening operation in improving the image and proposed an algorithm that detects for the edge after calculating mask-based gradient. And to evaluate the performance of the proposed algorithm, a comparison was made against the existing Sobel, Roberts, Prewitt, Laplacian, LoG edge detection methods, in illustrating visual images, and similarities were compared by calculating the MSE value based on the standard of each image.

In this paper, we propose a computationally efficient multi GPU accelerated image registration technique to correct the motion difference between the pre-contrast CT image and post-contrast CTA image. Our method consists of two steps: multi GPU based image registration and a cerebrovascular visualization. At first, it computes a similarity measure considering the parallelism between both GPUs as well as the parallelism inside GPU for performing the voxel-based registration. Then, it subtracts a CT image transformed by optimal transformation matrix from CTA image, and visualizes the subtracted volume using GPU based volume rendering technique. In this paper, we compare our proposed method with existing methods using 5 pairs of pre-contrast brain CT image and post-contrast brain CTA image in order to prove the superiority of our method in regard to visual quality and computational time. Experimental results show that our method well visualizes a brain vessel, so it well diagnose a vessel disease. Our multi GPU based approach is 11.6 times faster than CPU based approach and 1.4 times faster than single GPU based approach for total processing.

Flipped learning can be used as an innovative teaching method in science education. This study analyzes video clip produced by pre-service elementary school teachers for flipped learning and explore strategies to organize effective visualization. The pre-service elementary school teachers focused on providing information on macroscopic natural phenomenon using concrete case selection strategy for earth science class. They used marker and spatial transformation elements effectively, but their efforts to link the elements to the experience of students were not sufficient. In addition, it was very rare to put the contents into simplified drawing or provide extreme cases to enhance the imagery of students. In addition, it is necessary to provide specific case of multi-modal and link the material to the experience of students closely through familiar cases or analogical model to establish an effective visual teaching material. It may also be needed to present simplified drawing for enhancing imagery and provide extreme cases to make students have an opportunity to infer a new situation.

Body has been high-lightened as one of the most important theme since the philosophy and the arts are focused on it in the late 20th century. It would be of worth to study the characteristics of contemporary fiber-art works, especially done by Abakanowiz who has been regarded as a dominant pioneer in the contemporary fiber-arts from the viewpoint of inter-grade of the physicals and the mental. This paper, therefore, deals with the Abaknowiz' works in the context of human body and body-signs. Life and works might be classified into 5 stages: first, learning period since her birth in 1930, second, creation period of Abakans, third, remodelling period of Abakans, fourth, composition and dissolution period of Abakans and the last and fifth, new transformation period of Abakans. 'Abakans' through her whole life as an artist have been a plastic language and based ultimately on external human body but in various materials and forms. Abakan as a human-sign uses the past experiences and the texts of the other world in mixed and overlapped forms. Life-size Abakans by Abaknowiz can be easily understood as Abakanowiz herself and her Polish ancestor at the same time. The neuter Abakans with mashed face and obscure body is a expressive figure of coexisting world with opposite concepts like war and ideology, anxiety and freedom, man and woman, and etc. Human body as body-sign is an extensive image has existed since our forefathers and overlapped with the inter textual and the popular images. 'Abakans' that is our world and inner-self at the same time might be a window through which she tries to show what the world is.

This is a study on the application of a dialectic way of thinking in terms of design methods, and has contents about the formation of new visual and the ways of process that are triggered by cognitive introspection. A ccordingly, the study has its purposes in interpretation and recommendation of new methodological systems around dialectic principles and ways of thinking on the works of the Dutch Architecture Exhibition carried out in Korea in 2013, with the theme of "Reuse" among the aspects expanding since the reflexive modernization. Firstly, the basic features of Dutch designs were connected to dialectic ways of thinking. After studying the basic concepts of dialectics from Greek philosophies to Kant, Hegel, Marx and Benjamin, the aspects of applying them onto creative works such as art, architecture and design were methodologically systematized. Through this process, it was confirmed that the existing concepts are newly rearranged rationally, logically and scientifically based on dialectic ways of thinking rather than subjectively or emotionally. From the study of the 12 art works, it was confirmed that the value of use and potential obstacles have been used as a design solution. Also, the process which is juxtaposed with the result by itself has been expressed and causes the alienation effect. Therefore, such dialectic ways of thinking was organized into a procedural flow of contradictory recognition on situations, drive due to negativity, mutual penetration, mutual transformation, abstraction, verbalizing and creation of new concepts, and it was confirmed that such finding was valid in securing creative possibilities as 'New Uses' rather than 'Re-uses'.

This research is to analyze costumes of Greek Mythology Gods in films using Morris' semiotics. In film "Clash of The Titans", Zeus' costume of shining gold armored body suit and long manteaux expressed the limitless sublime. The definite form contouring body shape of his costume also demonstrated classical beauty. Hades' costume of dark colored armor, long manteaux, and transformation via smoke also described the limitless sublime. The unbalanced and irregular shaped armor showed ugliness. In "Percy Jackson & The Olympians: The Lightening Thief", the armor and long manteaux of Zeus showed the limitless sublime. The beauty of his body and his sophisticated business wear indicated classical beauty. These features were also present in Poseidon's costume as well. The limitless sublime and ugliness are implied in Hades' look by portraying him as having a monster body with horns and wings, and his costume of punk look. In "Immortals", gods of Olympus wore clothing that was reminiscent of Egyptian times, which represented a time of strong royal authority, in order to expose the limitless sublime. Classical beauty was shown in the beauty of their body. Titans' costumes and look of non-human being were composed of black and red to present ugliness. The inherent meanings of Gods' costumes are death of god, patriarchy, and the good triumphing over the evil. The Greek gods are not held in the same reverence in the contemporary society. However mythology inspires lots of visual creations. The results help to accumulate a creative design database for fashion.

Throughout her life time, Edith Head produced cinema costumes for over one thousand movies. She was the leading cinema costume designer in Hollywood. Since the Academy Awards added the area of costume design to be recognized [during 33 years of her work(1948∼1981)], she was nominated 35 times an awarded eight times. However, there were no significant studies done on her work or accomplishments although she was acknowledged as an ingenue and creative designer who elicited artistic effects by reflect character's images through their costumes. The purpose of the study was focused on revealing Edith Head's life and work as her creations had a great impact in he field of cinema costumes. It was also to emphasize the forceful affect of cinema costumes on fashion and to disclose the powerful influence of cinema costume designers. The method of the study includes reviews of literature, movies for which she created costumes, her own possessions, and fashion magazines as well as her works that were nominated and chosen for the Academy Awards. Edith head's emphasis in costume design was based on a blend of both simplicity and sophistication avoiding excessive exaggeration and transformation in her work. Her work was also realistic and contemporary. She developed a dramatic ambience through an innovative design while preserving the actor's individual character and uniqueness. Through this accept her her work was highly renowned as an art form as it was gaining popularity. She was also a dominant figure who influenced trends in the areas of fashion magazines, uniforms, and public clothing. In the review of her cinema costumes, it was revealed that the styles of cinema costumes can be as quickly adapted by the public as movies are viewed because the cinema costumes are highly projected through a visual channel. Subsequently, a follow up study on the affect of cinema costumes on fashion would be beneficial.

In this paper. we Propose a robust and fast image registration technique for motion correction in brain CT-CT angiography obtained from same patient to be taken at different time. First, the feature points of two images are respectively extracted by 3D edge detection technique, and they are converted to locally weighted 3D distance map in reference image. Second, we search the optimal location whore the cross-correlation of two edges is maximized while floating image is transformed rigidly to reference image. This optimal location is determined when the maximum value of cross-correlation does't change any more and iterates over constant number. Finally, two images are registered at optimal location by transforming floating image. In the experiment, we evaluate an accuracy and robustness using artificial image and give a visual inspection using clinical brain CT-CT angiography dataset. Our proposed method shows that two images can be registered at optimal location without converging at local maximum location robustly and rapidly by using locally weighted 3D distance map, even though we use a few number of feature points in those images.

This paper describes a methodology for the development of models of discrete event system(DES). The methodology is based on transformation of continuous state space into discrete one to homomorphically represent dynamics of continuous processes in discrete events. This paper proposes a formal structure which can couple DES models within a framework. The structure employs the DEVS formalism for the DES models. The proposed formal structure has been applied to develop a DEVS model for the human cardiovascular system. For this, the cardiac cycle is partitioned into a set of phases based on events identified through VisSim simulation in the CS of the electrical analog model. VisSim is the simulation tool of visual environment for developing continuous, discrete, and hybrid system models and performing dynamic simulation. For each phase, a CS of the electrical analog model for the cardiovascular system has been simulated by VisSim 2.0. To validate this model, first develop the DEVS model, then simulate the model in the DEVSIM++ environment. It has same simulation results for the data obtained from the CS simulation using VisSim. The comparison shows that the DEVS model represents dynamics of the human heart system at each phase of cardiac cycle.
