Depaysement, suggested by the well-known surrealist Rene Magritte, has been used for and applied to many media. Application of depaysement through various media such as TV, commercial, and advertisement, attempted to provide interest by deviation from fixed ideas and visual shock, placing common objects in new and strange environment. The study applied screen projection mapping using a transparent screen and objet for different purposes to projection mapping media, applying depaysement to the artwork 'Illusion' in order to suggest visual pleasure, possibility as a new media, and projection mapping using transparent screen and objet. The work cases were suggested by applying expressive methods and effects according to three classifications - modulation of space, combination of conflicting images, and transformation and change of objects - in depaysement, and analyzed by types based on classification of the layout, typography, image, color, and time. Through 'Illusion,' new objet and characteristics of the media are applied and expanded by using projection mapping and depaysement.

The purpose of this thesis is to suggest objective basic data for the super graphics in the urban landscape through the quantitative visual quality analysis. For this, the image structure of super graphics have been measured mainly by questionnaries and semantic differential scle method and analyzed by the method of factor analysis, means and multiple regression. Degree of visual preference have been measured mainly by questionnaries and likert attitude scale method and finaly these data have been analyzed by using the stepwise method. The data were collected by presenting 12 super graphics photographs-4 each sample pictures from the 3 each selected districts representing typical urban landscape style(central business district, shopping district, apartment complex). Observer groups were categorized as professionals, students, the others. Result of this thesis can be summarized as fallows: 1. From all 12(3${\times}$4) sample super graphics, the value of each semantic differential scale among the observer groups were presented significant group difference. But no significant difference of the S.D. scale value were observed among central business district, shopping district and apartment complex super graphics. 2. For all experimental points, 4 types of factor have been observed. Factors covering the image of super graphics were found to be the evaluation, the intimacy, the potentiality and the tidiness. 3. Main factors of the super graphics image and factors indicating the group variations yielded high significance between areas. 4. The harmony with surrounding environment, the proper selection of super graphics subject yielded high values for all groups. Especially, the good color sense with building was the most important variable determining the degree of visual preference. 5. The urban C.B.D. super graphics obtained 5∼12 ranks of regional visual preference and the shopping district super graphics obtained 2∼11 ranks, and apartment complex super graphics obtained 1∼7 ranks.

Recently, the color of vehicle license plate has been changed from green to white. Thus the vehicle plate recognition system used for parking management systems, speed and signal violation detection systems should be robust to the both colors. This paper presents a vehicle license plate recognition system, which works on both of green and white plate at the same time. In the proposed system, the image of license plate is taken from a captured vehicle image by using morphological information. In the next, each character region in the license plate image is extracted based on the vertical and horizontal projection of plate image and the relative position of individual characters. Finally, for the recognition process of extracted characters, PCA(Principal Component Analysis) and LDA(Linear Discriminant Analysis) are sequentially utilized. In the experiment, vehicle license plates of both green background and white background captured under irregular illumination conditions have been tested, and the relatively high extraction and recognition rates are observed.

Recently various types of driver assistance systems have been used for automobiles. In 2008, the U.S Congress passed a law which required that most cars be equipped with devices to warn objects behind the vehicle. Because of that, market of rear view cameras is expected to rise dramatically. Therefore many suppliers try to provide a wide angle camera for car makers. But a high distortion is caused by the wide angle might result in lower image quality. In order to improve the image quality, normally we use an algorithm to correct a distortion. Though we can improve the distorted image by correction algorithm, we must pay more cost to use it. In this paper, we propose a new optical system reducing a distortion in contrast to a conventional lens without cost. In other words, we can see only an area of interest. That is similar to reducing a field of view. Using a new optical system, we can get a less distorted image. In order to view an area of interest, we introduce an off axis optical system having refractive surfaces and reflective surfaces. In this paper, we describe the results of design and, evaluation of an off axis wide angle compact imaging system. In comparison to conventional wide angle lens, we can get the improvement of MTF, distortion, and lateral color aberrations. And we also can reduce a total cost because we don't need the outer apparatus or bracket to mount on the car.

This study aims to develop a mechanic embroidery bag design that reflects the symbolic image of Korean independence activists who sacrificed for the country so that today's Korea can exist. As a research method, the theoretical consideration and image collection of independence activists were conducted through a literature review and visits to the memorial halls of six independence activists. The bag design was developed using mechanic embroidery textile of 12 motifs manufactured in previous studies through the computer mechanic embroidery sewing machine, and the types were limited to totes, Boston, clutches, baskets, shoppers, hover bags, and hat boxes. The results of this study are as follows. First, it was found that the dense light and shade and delicate color expression of each motif design were the most important and achieved through the proper selection and utilization of embroidery yarn according to the mechanic embroidery expression technique for developing in-depth textile materials. Second, unlike in the past, when machine embroidery was difficult to handle, the spread of embroidery CAD and computer machine embroidery sewing machines made it easier for individuals to develop embroidery products. Third, this study once again emphasized the symbolism of Korean independence activists who sacrificed for the nation to exist at a time when it needs to be recognized due to the lack of fashion and diversity in cultural products containing historical and cultural meaning and values of the country. This study was able to develop computer machine embroidery textiles and various bag designs using various mechanic embroidery expression techniques that can highlight the symbolic image of each motif.

This research was focused on observing the effect of Makgeolli's selection attributes on customer satisfaction, recommendation intention, and repurchase intention. The purpose of this study was to examine to present a marketing-related suggestion by finding the components that needs to be discussed in order to satisfy the customer and lead to positive word of mouth and repurchasing in the perspective of a corporation. The evidence to achieve the research purpose can be summarized as below. To begin with, the causes of Makgeolli's selection attributes were classified into 9 types, which are design and ad image, expertise and tradition, drinking experience and in harmony with food, taste and freshness, materials and origin, brand image, flavor and color, alcoholic and nutrition, and finally price and recommendation. And it showed up that the average importance of the taste and freshness is the highest. Moreover, the study on the Makgeolli's state of being potable showed up that the drinking number was no more than once a month, and one drink was almost all less than a bottle. The drinking place was usually tavern, and word of mouth was the most often used information medium that contacted Makgeolli. The potential of the Makgeolli's globalization is 80.6% which added positive and very positive, that enables us to infer that the Makgeolli's global dependency is very high. Third, from the 9 types of classification mentioned before, taste and freshness, and price and recommendation were proved to be influential in satisfaction, and recommendation is affecting the repurchase intention and the recommendation intention.

This study examined the physical attributes and heat treatment characteristics of glass beads excavated from the Gimhae area, which is the location of Geumgwan Gaya. This enabled classification of surface characteristics of the beads based on the investigation of the color, size, and shape. The glass beads were classified into eight color systems, with purplish-blue beads as the representative color. Bead size was categorized into three types depending on the outer diameter and how it increased over time. Bead shapes were categorized as round, tubular, or doughnut-shaped based on the inner diameter and length, with round being the typical shape. According to the degree of heat treatment, there are three types of cross-section for glass beads that are manufactured by the drawing technique, most of which are the HT-III type. In addition, it is estimated that the heat treatment technology has more considerable effects than other methods. Through non-destructive analysis, the chemical composition was obtained and categorized as flux, stabilizer, and colorant. Analysis confirmed the presence of 63 and 9 pieces in the potash and soda glass groups, respectively. Overall findings from the study highlighted a correlation between the chemical composition and the external factors such as color, size, shape, and manufacturing technology of glass beads recovered from Geumgwan Gaya, revealing characteristics related to that time and region.

This study is considered about the Taekwondo(跆拳道) uniform classified by period and analyzed the current Taekwondo uniform. And founded on this contents, new designs of uniform, that a functional side are considered and can symb이ize the identity of Taekwondo, are presented through this study. Ancient times to the present time, the Taekwondo uniform classified into three types according to 'Period of putting on our nation's costume'(three kingdoms${\sim}$Joseon(朝鮮) times), 'Period of confusion on uniform'(Japan's colonial rule of Korea${\sim}$-the early 1970s), 'Period of the settlement on official uniform'(the late 1970s-the present time). And besides, the shape of our nation's costume in ancient times is succeeded until Joseon times and this basic style becomes the outset on the current Taekwondo uniform. The designed uniforms are connoted the notion of the aesthetic appreciation in Korean traditional costume, that is, a symbolic, dignified, moderate appreciation with the consideration of a functional side for Taekwondo. And the contents on the presented designs are classified into 'shape, pattern, color'. First, these designs that are adapted the shape of Baji(바지) Jeogori(저고리)-belt, which have symbolized our nation's costume, and the shape of Bacja(배자) had used in Joseon times, are connoted a 'traditional appreciation with functional side'. Second, these designs, which are adapted the patterns of the active image(a bugbear, flying horse, tiger for embroidered patches, Taegeuk(太極)) in a modern style, express a 'symbolic, dignified appreciation'. Third, these designs are well-matched a black and white color with multicolored stripes(saekddong, 색동), and its ones are connoted a 'moderate and symbolic appreciation'.
