The cyber world is organically alive. It continues to evolve as humans interact with it. Real life and virtual reality are directly or indirectly connected through technology at the network terminal. Branding, in the cyber world, is created by BI(Brand Identity), using designed symbols and logotype developed with digital technology. The objective of this study is to improve the brand value of enterprises and organizations through the use of moving images to adapt to the mobile environment in this rapidly changing cyber world. First, the basic concepts of brand identity, structure, and integrated brand identity were studied. Next, case studies of overseas enterprise branding such Swisscom, HP, BBC were analyzed examining their design concepts and implementation of integrated moving brands. Finally, moving brand identity is explored, for value enhancement, in my projects in ACM SIG CHI 2015, HCI Korea 2014, Aegis Ship 'Yulgok YiYi.' with a discussion of design planning and results. This treatise will contribute to the improvement of brand strategy and design in this country.

This paper proposes high performance coprocessor architecture for real time dense disparity computation based on a phase-based binocular stereo matching technique called local weighted phase-correlation(LWPC). The algorithm combines the robustness of wavelet based phase difference methods and the basic control strategy of phase correlation methods, which consists of 4 stages. For parallel and efficient hardware implementation, the proposed architecture employs SIMD(Single Instruction Multiple Data Stream) architecture for each functional stage and all stages work on pipelined mode. Such that the newly devised pipelined linear array processor is optimized for the case of row-column image processing eliminating the need for transposed memory while preserving generality and high throughput. The proposed architecture is implemented with Xilinx HDL tool and the required hardware resources are calculated in terms of look up tables, flip flops, slices, and the amount of memory. The result shows the possibility that the proposed architecture can be integrated into one chip while maintaining the processing speed at video rate.

This paper proposes a humanoid robot performance system for performing in public places, such as an event, exhibition, or street performance. The system of modular structures can be moved easily, and can be played by a module or a combination of modules. The system developed with open source-based software and hardware is easy to adapt and improve. The robot performance control program for controlling robots, displays, audios, videos, and performance instruments was developed using the open source language, Processing. The performance instruments were developed using the open source hardware, Arduino. The contents of the robot performance were composed of scene-specific image, background audio, computer graphics, and videos. For their control and synchronization, the performance control program communicates with the humanoid robots and the performance instruments. In addition, performance accessories required to represent the performance concepts are produced by 3D modeling and printing. In a public place, the robot performance is performed with the theme of celebrating a Halloween day.

displacement mapping enables us to add realistic details to polygonal meshes without changing geometry. We present a real-time artifacts-free inverse displacement mapping method. In each pixel, we construct a ray and trace the ray through the displacement map to find an intersection. To skip empty regions safely, we traverse the image pyramid of displacement map in top-down order. Furthermore, when the displacement map is enlarged, intersection with bilinear interpolated displacement map can be found. When the displacement map is at distance, our method supports mipmap-like prefiltering to enhance image quality and speed. Experimental results show that our method can produce correct images even at grazing view angles. Rendering speed of a test scene is over hundreds of frames per second and the influence of resolution of displacement map to rendering speed is little. Our method is simple enough to be added to existing virtual reality systems easily.

Silmido [실미도 2003] captures the covered historical reality and describes the spectacular training process of the special army stationed at Silmido in vivid detail. As a result, a fictional space is turned into a reality film. The film shows ideological inconsistency of the critical view about the fascism of government authority and at the same time the political aid about government authority. The film creates dramatic and friendly effect through melodramatic and emotional exaggeration called sinpa about historical events to produce the pleasure of assimilation based on the trust of the audience. Here, individual assimilation is subjectivity achieved through the general sympathy coming from the tragic national discourse. Silmido appeals to the imaginary community not in a logical but in an emotional way. The spectacular action and realistic images are supported by national tragedy divided into the South Korea and the North Korea, and integrated sentimentalism to amplify the tragedy. Silmido tries to strengthen the tragic situation caused by the division ideology through this sentimentalism called sinpa. In contrast to the brutality of the relentless military regime, the sacrifice of good-hearted Silmido force members is heroically portrayed.

The electromagnetic (light) waves have a limitation to penetrate media, ie, water and sea-bottom layers, due to high energy attenuation, but acoustic (sound) waves play as the good messenger to gather the underwater target information. Therefore, the acoustic methods are applied to almost all of ocean equipments and technology in terms of in-water and sub-bottom surveys. Generally the sound character is controlled by its frequency. In case that the sound source is low frequency, the penetration is high and the resolution is low. On the other hand, its character is reversed at the high frequency. The common character at the both of light and sound is the energy damping according to the travel distance increase.

In general, the cut or dissolve or etc., collective changeover represents the change of scene in the film. Animation film makes scene's various parts to allow intended sensibility and narrative factors by special manufacturing skill generating frame image one by one and transfer it to the different symbolic dimensional expression. Nowadays sequential scene composition is not any more the unique special treatment for 2D animation according to image handling skill like morphing, metamorphosis, etc. becomes diverse and elaborate. But 2D manual animation makes spectator to be absorbed into different visual dimensions continuously and strongly beyond character and background, namely object and space. that is 2D manual animation's strong attractiveness. Finally these characteristics enable literary function which makes it possible to do delicate metaphorical through full scene composition basis and to communicate a implicative meaning system The analysis about scene broke boundary between symbolic perspective world and plane formative world and it became more diverse and complicated. Hereupon the analyzing the composition basis of formative element in the animation film scene and it's application effect make it helpful to analysis and application in the modern image scene having new absorbing methods

Plants are altered not only in the outward appearance but also in their physiological and biochemical properties with reaction to the environmental stresses; particularly, the biosynthetic system of protein in situ rapidly responds to this. In order to investigate the change of properties of polypeptides in rice plants induced by several stresses, the seedlings were subjected to exposure to NaCl, drought, and low and high temperatures, respectively, and then some aspects of polypeptide variations were compared. Without exception, the rice plant, which is somewhat tolerant to environmental change, shows the alteration in several polypeptides. Moreover, newly synthesized polypeptides were observed in response to stresses. The existing proteins for the primary metabolic pathways were markedly decreased as each treatment progressed.

Today, computer graphics have moved into spotlight within many related fields. The use of computer graphics in many fields as well as in design is now universalized. More than ever, those fields which utilize virtual reality are being vigorously researched and are rapidly progressing. Many advanced countries are obtaining positive results, allowing the world to learn about their culture and history by using virtual reality techniques for the restoration of cultural property. Above all, the West has utilized the diversity of the CAVE system which could best express the artificial system among virtual reality systems. However, in Korea this technology remains in its early stages of development. Moreover, the field, digital restoration of cultural property, which will be discussed in this study, hasn't yet been explored. Accordingly, this study presents the way of digitally restoring cultural property based on the CAVE through the empirical research and suggests the significance and possibility of digitally restoring cultural properly in the CAVE system. For them, this study processes the digitally restoring of Pulguksa Temple and Sokkuram and refers to the limitation and the future study following the investigation of CAVE and the introduction of applicable examples in abroad.
