Digital filters are indispensible element in digital signal processing area. The performance of digital filter based on adding and multiplying operation, such as computational speed and power consuming is determined by the orders and coefficients of filter which has on effect area of semiconductor chip when it is implemented by VLSI technology. In this research, in order to performance improvement of digital filter, we proposed the algorithm to speed-up the operation of digital filter associated with the minimum signed digit representation of binary number system and method to simplify the digital filter design associated with common subexpression elimination. The performance of proposed method is evaluated by the computational speed and design-simplicity by experimental implemented digital filter on FPGA.

Analyzing the inner meaning and expression of philosophy by analyzing the composition, symbolic expression, and style of the film with high artistic perfection, which contains the spirit of the times, considers human beings through society and history, and raises awareness of life and the present generation. It will be a very meaningful and valuable study in film as art. The movie 'Rome' was cut into the rest of the public's mind by being tempered, hidden and omitted, and the color was black and white. Many aesthetic attempts can be found through symbolic images expressing the ironic message of maid's daily life as a race, capital, socially oppressed history. It can be seen that he expresses his own authorism visual language by drawing symbolic expressions through many contrasts and symbolic expressions through objects. The analysis of commercial films containing these artistic values is expected to help in the future production as a measure of the progress of art films and precedents of authorism expression techniques.

Art has evolved into remarkable changes in its art form maintaining a close link with the contemporary scientific technologies that gave birth to new tools of expression in each era. Animation is an art form in an inextricable connection with technological aspects because it was spawned by the technical background like movies. In this regard, animation is often viewed very strongly by technical advancements in terms of an aesthetic approach. John Whitney Sr., one of the pioneers in computer graphics arts, turned his attention to the new technology called computer graphics as a means to visualize images and movement. The advent of a new medium had a strong influence not only on tools and means for novel expression but also on the gradual shift in thinking about arts and even the audiences' taste. In the 1980s, animation was combined with computer technology and the rapid progress of computer graphic technology opened up the era of new visual aesthetics, Today, the development of digital technology presents a different dimension of realism, either advocating hyperrealism by digital actors or presenting new illusionism by classic cartoon characters emphasized in a distortion or metamorphosis from a real life in order to consolidate animation realism. Based on the two perspectives mentioned above, this study can identify methods of digital character appropriation focused on the works of the ACM SIGGRAPH Asia and find how the relationship between art and technology has changed the digital realism and evolved the digital character as the digital technology has developed.

As the information age grows rapidly, the amount of digital texts has been increasing as well. It has brought an increasing of visualization case in order to figure out lots of digital texts. Existing visualized design of digital text is merely concentrating on figuration of subject word through adoption of stemming algorithm and word frequency extraction, prominence of meaning of text, and connection in between sentences. So it is a fact that expression of rhythm that can visualize sentimental feeing of digital text was insufficient. Syllable is a phoneme unit that can express rhythm more efficiently. In sentences, syllable is a most basic pronunciation unit in pronouncing word, phase and sentence. On this basis, accent, intonation, length of rhythm factor and others are based on syllable. Sonority, which is most closely associated with definitions of syllable, is expressed through air flow of igniting lung and acoustic energy that is specified kinetic energy into sonority. Seen from this perspective, this study examines phonologic definition and characteristics based on syllable, which is properties of digital text, and research the way to visualize rhythm through diagram. After converting digital text into phonetic symbol by the experiment, rhythm information are visualized into images using degree of resonance, which was started from rhythm in all languages, and using syllable establishment of digital text. By visualizing syllable information, it provides syllable information of digital text and express sentiment of digital text through diagram to assist user's understanding by systematic formula. Therefore, this study is aimed at planning for easy understanding of text's rhythm and realizing visualization of digital text.

The form or interpretation of today's communication design lies in content development and storytelling to the designer. However, the understanding as well as exteriment of the mechanisms behind content creation remain an obscure concept. Particularly given the rapid development of digital technology, since the 1980s typography has been quickly transforming itself from its static state to the more dynamic'Type in Motion'. following this came the need for solid research in'Type in Motion'as the best means of presenting story content and form The previous passage has studied the effectiveness of'Type in Motion'in presenting this kind of content. Type in Motion has allowed vast developments in the methods of story presentation. It is Due that today's digital technology has given many benefits to the designer, but on the other hand, it has required a more diverse understanding of digital design. furthermore, even the designers in digital typography lack the understanding and research in'Type in Motion'not only as a mode of visual language but also of verbal language. Given this point· in hand, the entire interpretation and interrelation of story and'Type in Motion'can be considered essential, given their shaping of effective digital typography.

The application of computer graphics, which is characterized by reality, has even reinforced reality of image and motion expression in digital animation. But reality of digital animation succeeds to traditional aesthetic characteristics of animation for overcoming physical limitations of the real world and realizing imagination through transformation, rather than copying actuality as it is. But it does not succeed to drawing animation wholly. Digital animation adds cartoonish transformation, based on three-dimensional realistic expression and those animation situations look as if they get over realistic restrictions, while drawing animation constantly reminds of mediality in drawing motion, based on two-dimensional plane and handwork. n other words, cartoonish exaggeration that is intermittently inserted between these reinforced realities, expresses digital animation's own aesthetic characteristics as a dialectical sum by crashing into contrast coming from a cross between reality and imagination.

Since the 1990s, digital technology has been actively applied in the field of heritage, and this presents a new possibility of using cultural heritage as a way to utilize the original cultural data that was previously recorded and stored. Methods of interpreting cultural heritage have been particularly diversified due to various external circumstances such as COVID-19 and time constraints, and the use of contactless digital content has played a significant role in built heritage that cannot be moved. Building Information Modeling (BIM) technology is considered as a way to properly express the authenticity of built heritage, but simply creating built heritage content with BIM cannot express the authenticity of cultural heritage. Therefore, it is necessary to show the reliability of the process of content production through an authorized institution and to provide the information of members on the content. This study intends to contribute to the field of digital heritage by suggesting ways to improve reliability and express authenticity in the production of built heritage content.

The development of digital technology has not only led to the development of expressive technology, but also to change in the process of production, expression media, production formats and methods, and communication with the audience. In one form, motion poster using LCD display instead of paper poster was introduced. This not only suggests the generation of posters with sound and movement on the ground, but also the possibility of expansion using the features of a platform called LCD displays. As part of this extension, this paper focuses on the "interactions" element and suggests a new interactive motion poster.

This study is focused on subjective images that are produced before visualization in the digital information environment and on characteristics of objective, dynamic image expression that specifies the subjective images. In this study, the visual world that works in the action of "see"is expanded into vision of eyes, vision of brain, and vision of camera. Also we have redefined the definitions of image and its materialized image, yeongsang. It is defined that image contains a strong meaning of consciousness and mind, and that yeongsang involves vision in which constantly changing information of light is created and reproduced by physical processes. We made it clear that image expression in the 21 st century is becoming more generalized, simplified, and concentrated, by the digital technology, from existing specific non-real images to "informationalized" non-real images. This means that there exists an intrinsic difference in the expressional form of the modern analog environment and that of the recent digital environment in the area of yeongsang communication. Along with development of technology, image information raises plastic reality through indirect experience in the virtual space by expanding the sensual faculty of human. However, there also is a tendency for humans to rely more on technology instead of utilizing their creative faculty. Image expression by“the digital information environment” in the 21st century will pursue two sides; one is to shift from external expression of the human body in the cyber space to internal expression, and the other is to internalize the image world and make it connected worldwide. Further research is necessary in these fields.ary in these fields.
