This paper presents an ARM-based SOC bus transaction verification IP and the usage experiences in SOC designs. The verification IP is an AMBA AHB protocol checker, which captures legal AHB transactions in FSM-style signal sequence checking routines. This checker can be considered as a reusable verification IP since it does not change unless the bus protocol changes. Our AHB protocol checker is designed to be scalable to any number of AHB masters and reusable for various AMBA-based SOC designs. The keys to the scalability and the reusability are Object-Oriented Programming (OOP), virtual port, and bind operation. This paper describes how OOP, virtual port, and bind features are used to implement AHB protocol checker. Using the AHB protocol checker, an AHB simulation monitor is constructed. The monitor checks the legal bus arbitration and detects the first cycle of an AHB transaction. Then it calls AHB protocol checker to check the expected AHB signal sequences. We integrate the AHB bus monitor into Verilog simulation environment to replace time-consuming visual waveform inspection, and it allows us to find design bugs quickly. This paper also discusses AMBA AHB bus transaction coverage metrics and AHB transaction coverage analysis. Test programs for five AHB masters of an SOC, four channel DMAs and a host interface unit are executed and transaction coverage for DMA verification is collected during simulation. These coverage results can be used to determine the weak point of test programs in terms of the number of bus transactions occurred and guide to improve the quality of the test programs. Also, the coverage results can be used to obtain bus utilization statistics since the bus cycles occupied by each AHB master can be obtained.

The purpose of this study is to propose future-oriented high-rise buildings where the vehicle is parked at the top of the building. At the same time, the vehicle is used as a part of the building along with the advent of the era of autonomous driving. The suspended structure is proposed as a suitable structural system for architectural planning. This system is free to design because there are no limitations on column planning compared to conventional designs. In particular, the low-floor plan can be used as an open space because colums are not arranged in the lower-floors. Thereby opened low-floor plan has advantages that visual perception of the space is improved, noise problems along the side of the street is solved and planning underground parking spaces are easier. These advantages can solve the problem of overlapping columns with vehicle traffic in the building. However, there are some problems that the suspension structure is mainly a formal form and the usable area is small compared to the core area because it is a core-oriented structural system. In this regard, a new structural system was proposed by combining the concept of suspended structure and cable stayed column. Therefore, this paper analyzes the existing style of high-rise housing suspended Structure and proposes a new structural system and the concept of design for autonomous vehicles.

Applying VR technology to animation areas is emerging as a trend of recent years. So if you use this VR technology in traditional ink animation, 2D art piece is expected to be equipped with a new narrative style and visual and auditory language, making it a new animation genre. There's a lot of technical difficulties in putting the existing 2D ink image on a 360 degree display. VR ink animation has been created that gives depth to VR space by using layer extraction method based on depth of distance and placing layers extracted on curved surface that is aligned with depth in 360-degree space in the image of ink painting, which is the background of traditional ink animation. In the text, we took an overview on problems generated in extracting layers of distant view, close-range view and middle distant view from the existing image of ink painting and made suggestions of an effective way to approach them.

Contemporary young people reveal their own personal values through the fashion that creates visual looks. Since 2000s began, young generations who are self-centered, value their own personality and constantly seek for changes form the main axis of fashion. In particular, the lower half of the body that has begun to be exposed outward has become the region that they want to expose as more ideal region than the upper half of the body. Further, young generations always have interest in fashion, and female college students in their early 20s are regarded as the group that values the aspects of pleasure that involve clothes and tends to seek sensibility when purchasing clothes. With this background, this study aims to examine how the styles that apply to modern fashion and recent vogues are evaluated with a focus on skinny jean from jean pants styles preferred by female college students. Materials regarding theoretical background and photos were collected from fashion related magazines at home and abroad and from the Internet websites. Questionnaires were surveyed for 160 female college students aged 20 or 25 who live in Seoul, and the results show as follows: Many female college students enjoy skinny jean and follow the fashion. However there are consumers who cling to their own styles even in the fashion of skinny jen. Ironically, some consumers wear it although they consider it as an item that does not fit Koreans: they tend to consider perspectives from others rather than their own preferences. For example, they wear it in order to show it to their boy friends or because they want themselves to look slim. In addition consumers seem to use Dongdaemun Shopping Mall or Internet shopping malls that provide various and low-priced items rather than to use high-priced famous products. It is considered that this result is shown as above because the scope of the study was restricted to female college students in their 20s. Accordingly, it is suggested that further studies should extend their subjects to wider range of ages.

Purpose: The purpose of this study was to examine the eyesight and life habits of college students in an attempt to provide some information on the protection of their eyesight. Methods: The subjects in this study were 311 students in the department of dental technology at a college of health, on whom a survey was conducted. A crosstabulation analysis was carried out to show the joint distribution of general characteristics and several variables involving the use of glasses or contact lenses and life habits. Results: 77.5% of the students currently wore glasses due to weak sight. 9.3% took an eye test on a regular basis, and 31.2% did that every six months. As for the length of the length of daily mean reading time, 55.3% spent one hour or less reading books. The most common distance between eyes and books during their reading(44.7%) was 21 to 25. Concerning a reading posture, the biggest group(54.3%) lay down or lay on their face while they read books. 45.0 % spent less than an hour watching TV per day on average, and 27.0% were on the computer for 30 minutes to less than an hour per day on average. The greatest group(63.0%) made use of basic indoor lighting when they were on the computer at night, and 62.1% saw eye doctors to take an eye test. In relation to how to protect eyesight, the biggest group(50.5%) spent less time being on the computer. Conclusion: As the eyesight of college students fails due to reading, TV, computer, and improper ways and posture of doing or using those things, every college definitely should provide education on eye health as one of general education courses.

Futurists objected the existent style, that is the conventional fashion, and took part in these disciplines of fashion to make clothes the instruments being able to represent the individuality. Giacomo Balla and fortunato Depero, pain-ters who in 1915 were to work with Diaghilev's company, were the first to see clothing as a dynamic interfaced between th body and the atmosphere, between physical gestures and the urban context, which could be translated into encounters between forms and colours, volumes and architecture. For them, clothing began to exist as an object and an event, something to be removed from a mainly static conception and made mobile, active. The interaction between movement and clothing was based on the relativity of perception : the appearance and disappearance of the body produced points without dimension or duration which served, as Balla wrote in the Futurist Mnaifesto of Men's Clothing to“renew incessantly the enjoyment and impetuous movement of the body”. The historical achievement in the effort for the reformation of Futurist, Art to Wear. First, for Futurist, clothing is removed from a static conception and focused on dynamics. Second, Balla used asymmetry in men's clothing. Moreover he supposed dynamic men's clothes by using optical intersection. Third, the after image of Chronophotograph represented rapidity. This rhythmic expression is the fore-runner in Optical and Kinetic Art of Visual Art. Fourth, Futurist emphasized flexibility in fashion. They aimed to create‘Clothing Machines’whose parts would interact to aceelerate the real and virtual, inner and outer movement of the human being. Fifth, the variety and short life of cutting skills and colors are focused and‘Fast Substance’in fashion is admitted by Futurists. Futurist concern with clothing was not lim-ited its appearance in terms of cut and colour. What important was also the way it appeared and disappeared according to fashion. It was a“fast substance”, able to reflect rapid, sudden changes of social and aesthetic taste. To reach to the aim of internationalization, Gesamtkunstwerk in our Art to Wear, it is extremely meaningful to examine art fashion which is created under the conception of Gesamtkunstwerk production of avang garde artist in the early 20th century and look at formative conscious of truth, goodess and beauty synthetically which they faced on their works of art.

This study purposed to apply function form content, the three concepts that have been discussed by many philosophers since ancient times, to fashion design. Specific research goals are : first, to define fashion design based on the three concepts : and second, to examine how each of the three concepts function-oriented, form-oriented and content-oriented design have been expressed in women's fashion in the $20^{th} century. For these purposes. the author considered Morris' semiotics, which is the theoretical background of the three concepts, reviewed previous researches in design area, and applied the findings to fashion design. According to the result of applying the threefold structure of semiotics. which is the theoretical background of the three concepts, the pragmatic dimension of fashion design comprehends all functional rules related to the use of dress such as body motion and protection, health and safety. air flow and durability, and its syntactic dimension comprehend all the formal elements of visual design such as the structure, shape, line, color and material of dress. The semantic dimension of fashion design includes the symbolic meanings of dress expressed by emotion, sentiment and images. The three dimensions exist interdependently with one another. According to the result of considering the characteristics of the three concepts in the scope of women's fashion in the $20^{th} century. function-oriented design is characterized by practicality and simplicity, and has been expressed as the fashion of functionalism in the 1920s, that of minimalism in the 1960s, and the basic style from 1970s to 1980s, 1990s and the present. Form-oriented design has pursued aestheticism, putting stress upon form, and has been expressed with organic shapes imitating patterns found in nature in the 1950s and with optical art fashion in the 1960s. Content-oriented design attaches importance to transmission of delicate meanings related to the mental world of human beings, and is represented with symbolic forms. Such a characteristic has been expressed in fashion in the early 20th century influenced by surrealism and, with various types of design breaking established forms as well as metaphors and humors that characterize design in the late 20th century.

Personal image concerns a person's talent, expertise, as well as the internal and external image. It is a core value that differentiates one individual from another. As personal branding via personal image management has become more important, there is a fast-growing number of online systems that provide self-test programs to analyze one's style and habits and also provide expert advice for not only styles but lifestyles as well. This study develops a systematic and objective personal image consulting system and offers basic information for the research of personal image making. For that purpose, the study attempts to examine the present state of global companies that use online image consulting programs and analyze their digital content. The results are as follows: 1) two domestic companies, Colorz and Atzine, and seven foreign companies, notably Covet and Boutique, were brisk in business; 2) two types of personal image-diagnosis programs - Visual search and Virtual matching - are now in operation; and 3) mobile applications exist as an evolved personal image-diagnosis program. With an increased interest in such programs, various companies at home and abroad are establishing systematic and scientific analysis systems, which are needed for personal image-making online. Under these circumstances, domestic companies are also urged to enhance levels of image-diagnosis content and actual commercialization and utilization, to develop programs that enable objectified, systematic personal image-making. To this end, the results of this study may serve as a helpful tool to consider future directions.

Brands started to manufacture consumer-oriented products and look for active methods to appeal their brands to consumers, in the 1990s. As a result, actively adopting graphic design to clothing designs has recently become an important strategy among others. Graphic design has important significance in contemporary fashion design in the aspect that it has expanded the range of expressive methods by bringing over expressive methods of visual design, and has led to an increase in sales due to consumer satisfaction, but it has been vaguely handled together with textiles design, and research on the topic has been insufficient. Therefore this study aimed to clearly define the idea of graphic design based on documentary research, and analyze applying case and formative features of graphic design expressed in clothing, through case studies from 2004 to 2006, and derive the trends of graphic design expressed in contemporary fashion design. The results of this study are as follows. The common characteristics of images that reflect recent graphic design trends in fashion design are hand writing and irregular composition, and images that actively pursued these pointes were retro and craft images, and modern and sporty images reflected these graphic design trends in a comparatively passive manner. It is important to maintain style differentiation rather than indiscreetly adopting graphic design trends to clothing, and to appropriately apply trend characteristics of fashion design and other design areas. Expressive methods of design are expected to expand through appropriate application and development of graphic design, and can potentially provide a new solution to brand differentiation.

If the motion is universal over the differences between the ancient age and the modern age, and between primitiveness and civilization, It is required to be studied, which make it possible to discover the universally valid interpreting elements of various societies and cultural phenomena. The study on the motion, as a base of universal motion study on animation and character modelling is considered as a very important part. The sampled motion prototype was classified by the continuity and the synchronicity that is a basis of modular analysis and of motion flow. Koguryo's mural paintings in old tombs has been the heritage and the symbol of the nation's historical identity and pride in Korean history. Koguryo is obviously a part of Korean history, which are of Korean elements. Accordingly, the mural paintings that this study has explicated is the origin as well as the history of Korean visual animation history, while the analysed and restored motion prototype is a module of Korean motion with golden section proportion.
