Throughout the history of fashion and fashion collections, fashion design has been influenced by fine arts. Philosophy and concept of fine arts has been inspiration on the development of fashion design which brings on the close interrelation between fine arts and modern fashion. In order to analyze the affect of fine arts such as Pop art on fashion this study inquires into new perspective that considers different social contexts on the premise that acknowledges the essential difference between the genre of fine arts and design. This study researches the influence of Pop art which has been inspiration on fashion designers since the birth in the 1960s and often appears in recent fashion trends. In view of the results achieved in this study, Pop art-inspired fashion does not concern the aesthetic contemplation of everyday life in western society anonymously as in Pop art but deals with pop art as new ideas in a way that adopts images randomly from designer's convenience which is equivalent to the conception of pastiche. In addition, it was inferred that Peter Pan syndrome exert influence as a mental process and Kidult trend operate on Pop art-inspired fashion as a social phenomenon. On the basis of the theoretical background, the formative features in Pop art-inspired fashion from Spring/Summer 2000 to Spring/Summer 2004 collection has been analyzed. The results fall on the following four categories; those are the use of Pop color which resembles the Hard-edge technique in Pop art, direct appropriation of Pop art such as Andy Warhol and Roy Lichitenstein's works on clothes and accessories, adaptation of Pop art's subject using brand names of mass products or icons in mass culture as design motives, and application of representation method in Pop art such as Andy Warhol's silk screen techniques or Tom Wesselman's composition of pictures.

The purpose of this study is to examine misnomers about King Heungdeok's "Prohibition of Clothing" by comparing the writings of Jeongdukbon [正德本] and Juzabon [鑄字本], which were different versions of the original texts of "Samguksagi [三國史記]", with 11 related books written between 1948 and 2012. In addition, this study is reconsidered the terms about several clothes as well as the values of fabrics. The study has come up with the following conclusions. 1. We suggested the correction about a misnomer in the 11 books and the misnomers for fabric items appeared most frequently. The records of Jeongdukbon about some of the items were different from ones of Juzabon, especially regarding noble woman's sash were written according to the record of Juzabon in most of the related books. However, when the commonplace woman's sash was taken into consideration, we could suppose that the record of Jeongdukbon was more reliable. 2. We examined the terms for Yodae [腰帶] and Yoban. It can be inferred from the original texts that the Yodae were different in material and function compared to the Dae [帶]. In other words, the wearing position of male's metal Yodae was the waist, whereas the females wore their Dae made of fabrics on their chest. An example of this can be seen from the female clay images of Tomb Yonggang-dong [龍江洞]. Moreover, female's Yo and Ban were distinct items on the basis of documents. For this reason, we suggested that Yodae and Yoban should be separated and written in books. 3. We suggested that Ju [紬, silk tabby] might be valuable according to an result of analysis about the value of recorded fabrics. Besides, Po [布, hempcloth] presumably were used as higher quality fabric than Myeonju [綿紬, silk tabby] on some items because Po was graded on the density by each class.

The purpose of this study was to provide some preliminary results on application of 3D scan data of head shapes to the hat design and pattern-making. This paper defined necessary measurement items and concepts in 3-dimensional images of head shapes. And also it presented the methodology to pattern-making of 6-piece crown hat based on 3D data. It used the data of Size Korea to pick up and choose a head shape model with the average head size of Korean women in their twenties. Main results were: 1. The 3D scan data of head shape was better than the 1 dimensional measurement data. Because I could establish a hat pattern-making theory by the 3D scan data of head. 2. The 3D scan data provided the basis for conceptualization of basic measurement points and items for a better fit of hats as well as the definition of the basic hat circumference. 3. This presented a methodology for analyzing out head shape by 3D scan data, and allowed the derivation of the basic hat circumference from the maximum head circumference. 4. As the 6-piece Crown cloche hat made by this method fitted the head shape model perfectly, this methodology could suggest potential applicability to various hat design.

Bitewing and periapical radiographic techniques are used in clinical and epidemiological studies to assess crestal alveolar bone levels. The purpose of the present study investigated relationships between these techniques by assessing alveolar crest location at the same site. Bitewing and periapical radiographs were available from posterior quadrants of 120 subjects. The distance from cemento-enamel junction to the alveolar crest (CEJ -CR) was measured for each proximal surface from the distal of the cuspid to the distal of the second molar. Data were arranged according to the proximal surface examined, and bitewing and periapical measurements were compared using paired tests. The obtained results were as follows; 1. In maxilla, a significant t ratio with a P value of 0.05 or less was reached for 78% and in mandible reached for 39%. 2. Pearson correlations were calculated 32 surfaces (89%) had values below 0.70 and so, data obtained by these techniques can not be used interchangeably on an individual or group basis. 3. In situations where the periapical measure was greater than the bitewing, it ranged up to 20.7% greater with a mean 9.8%. Where the bitewing was greater than periapical, it ranged up to 51. 9% greater, with a mean 18.2%. 4. The percentage difference was greater in maxillary posterior areas than in mandibular molar, premolar areas. A lower prevalence of significant differences was attributed to relatively more simple root and favorable radiographic conditions in mandibular molar and premolar areas. 5. The anatomical limitations imposed on periapical radiographic technique, most often result in somewhat foreshortened radiographic images. This situation would tend to be accentuated by the anatomical restrictions of the hard palate. 6. Consequently, since the significant differences frequently exist between measurements obtained from bitewing and periapical techniques, it is important to define which technique is used.

The background fort this study is related to the concept of modern time and space which has been extended from physical space to virtual space in the present times witnessing the advent of the Fourth Industrial Revolution. Based on visual tactility and illusion in virtual reality, we intended to present the possibility of the interactions as realistic as the interactions occurring in reality. Regarding the scope of this study, we analyzed the relationship between illusion in game space and immersion in interactions based on the games used frequently among current virtual reality contents. The results of the study showed that the interactions in virtual reality occurred within the space converging the time and space and that the illusion of digital images had realistic position of reality without original. Research which investigates the interaction in virtual space and media projection method for real space and virtual space will provide useful basis for promoting technological development based on novel methods differentiated from existing image grammar and for identifying the content utilization methods.

This study aims at grasping the degree of change on the layout of newspaper through the analysis on the visualization of the Online Newspaper. It was analyzed on the basis of six dependent Online Newspapers. Six news companies' home pages and NAVER news homepage were compared and analyzed. As a result of the analysis, it has been found that the layout of the Online Newspaper has been changed rapidly through the visualization. Especially, the visualizations of some Online Newspaper have already reached the high level, and those of other newspapers are also under way rapidly. The visualization of the Online Newspaper is going on in the way that the size of images and the number of times of their being used in the news stories are increasing. Consequently, the visualization of the Online Newspaper follows the course of that of paper-based newspaper, and the relative importance of 'a newspaper that sees with an eye' to 'a newspaper that reads with an eye' grows bigger and bigger.

We have successfully developed the KASI (Korea Astronomy and Space Science Institute) Solar Imaging Spectrograph (KSIS), which has been originally upgraded from the KASI solar spectrograph that was able to record solar spectra for a given slit region and to inspect the response function of narrow band filters. A prototype KSIS was developed in 2004 by using a scanning mirror in front of the spectrograph slit and a SBIG ST-8XE CCD camera. Its main disadvantage is that it took a long time (about 13 minutes) to scan a whole active region. In this work, we have upgraded the KSIS by installing a much faster Dalsa 1M15 CCD camera, which gives a data acquisition time of about 2.5 minutes. The software for KSIS was also improved for the new CCD camera on the basis of component-based development method. We have successfully made a test observation for a simple and small active region (AR10910) using the improved KSIS system. Our observations show that H-alpha images for several wavelengths have typical features in a sunspot as well as a H-alpha centerline image is quite similar to a BBSO H-alpha image, demonstrating the capability of the KSIS system.

A source code is developed on the basis of Berreman's 4$\times$4 matrix formalism for the analysis of polarization transmission characteristics of twisted nematic liquid crystal display. By using the program, the polarization transmission characteristics of liquid crystal cells and polarizers are analyzed. For a normally white twisted nematic liquid crystal cell, we obtained a family of iso-contrast contours which helps to understand the viewing angle characteristics of the liquid crystal display device by using the cell. The program also help us to understand the variation of the degree of polarization as well as the deviation of the state of polarization of the light transmitted through the polarizer commonly used in the LCD according to the change in incidence angle. This result suggests the contrast of the images appearing on the LCD can be limited by the characteristics of the polarizer in addition to the liquid crystal cell.

A comprehensive methodology to characterize the interfacial reaction products of $SiC_p/2024$ Al composites is introduced on the basis of the experimental results obtained using XRD, SEM and TEM. XRD performed on the electrochemically extracted $SiC_p$ and bulk $SiC_p/2024$ Al composite have shown that the interfacial reaction products consist of $Al_{4}C_3$ having hexagonal crystallographic structure, pure eutectic Si having diamond cubic crystallographic structure, and $CuAl_2$, having tetragonal crystalloraphic structure, respectively. According to the images observed by SEM, $Al_{4}C_3$, which has been reported to have needle shape, has a hexagonal platelet-shape and eutectic Si is found to have a dendritic shape. In addition eutectic $CuAl_2$, was observed to form near interface and/or along the grain boundaries. In order to confirm the results obtained by XRD, the primitive cell volume and reciprocal lattice height of such interfacial reaction products were calculated using the data obtained from convergent beam electron diffraction (CBED) patterns, and then compared with theoretical values.

The purpose of this study was to provide instructional suggestions by investigating the spatial sense and spatial reasoning ability of 6th grade students. The questionnaire consisted of 20 questions, 10 for spatial visualization and 10 for spatial orientation. The number of subjects for the survey was 145. The processes through which the students solved the problems were the basis for the assessment of their spatial reasoning. The result of the survey is as follows: First, students performed better in spatial visualization than in spatial orientation. With regard to spatial visualization, they were better in transformation than in rotation. With regard to spatial orientation, students performed better in orientation sense and structure cognitive ability than in situational sense. Second, the students that weren't excellent in spatial visualization tended to answer the familiar figures without using mental images. The students who lacked spatial orientation experienced difficulties finding figures observed from the sides. Third, students had high frequency rate on the cognition and use of transformation, the development and application of visualization methods and the use of analysis and synthesis. However they had a lower rate on a systematic approach and deductive reasoning. Further detailed investigation into how students use spatial reasoning, and apply it to actual teaching practice as a device for advancing their geometric thinking is necessary.
