In order to pursue the traces of truth, boundaries set by man for convenience were crossed or Integrated leading to the discovery of new paradigms. Such phenomena including collaboration, convergence, crossover and etc. are expressed in various forms across the society and culture. In particular, development of digital technology is moving away from its previous color based on scientific, statistical and quantitative perspective by using diverse variables. Also, as the borderlines of genres become increasingly more ambiguous, various concepts of color blending developed rapidly. Thus These chaosmos-like color blending have created new contents. This research aims to understand the principle of color blending in Karim Rashid's work, which advocates the world of design in diverse fields from industrial products to architecture. The principle of color blending such as information change, source color and destination color, interaction, and etc. makes it possible to extract the expressed element and method of color blending. Meanwhile, the features of color blending such as integrated space and time, vague form, and narrative genre can be inferred from case analysis.

Recently, an iterative algorithm for finding the interior eigenvalues of a definite matrix by CG-type method has been proposed. This method compares to the inverse power method. The given matrices A, and B are assumed to be large and sparse, and SPD( Symmetric Positive Definite) The CG scheme for the optimization of the Rayleigh quotient has been proven a very attractive and promising technique for large sparse eigenproblems for smallest eigenvalue. Also, it is very amenable to parallel computations, like the CG method for the linear systems. A proper choice of the preconditioner significantly improves the convergence of the CG scheme. But for parallel computations we need to find an efficient parallel preconditioner. Our candidates we ILU(0) in the wave-front order, ILU(0) in the multi-coloring order, Point-SSOR(Symmetric Successive Overrelaxation), and Multi-Color Block SSOR preconditioner. Wavefront order is a simple way to increase parallelism in the natural order, and Multi-coloring realizes a parallelism of order(N), where N is the order of the matrix. Another choice is the Multi-Color Block SSOR(Symmetric Successive OverRelaxation) preconditioning. Block SSOR is a symmetric preconditioner which is expected to minimize the interprocessor communication due to the blocking. We implemented the results on the CRAY-T3E with 128 nodes. The MPI (Message Passing Interface) library was adopted for the interprocessor communications. The test problem was drawn from the discretizations of partial differential equations by finite difference methods. The results show that for small number of processors Multi-Color ILU(0) has the best performance, while for large number of processors Multi-Color Block SSOR performs the best.

This thesis has purpose of explaining that blur color is not only appreciated but also undecided spacial color in contemporary space design and examining effects of space experience through the light. In keeping such developments, blur color has been perceived as the object of another tool in contemporary space and has provided us with new views by providing various program, sensor and screen from digital media. With the expansion of blur color, light has changed a spacial color structural that is not simple meaning factor into the essential concept. So this research aims to understand the principle of blur color in Olafur Eliasson's work, which of the fine artist in diverse fields from installation art to media art. The principle of blur color such as deconstruction of vanishing point, dimensional transfer, color gradation, and fiction of visual perception makes it possible to extract the expressed element and method of blur color. Meanwhile, the features of blur color such as sense of depth from viewpoint changes, hybrid from collapse of order, media metamorphosis from reconstitution and interaction from uncanny can be inferred from case analysis.

Currently, since the black-white QR (Quick Response) codes have limited storage capacity, color QR codes have been actively being studied. By multiplexing 3 colors, the color QR codes can allow the code capacity to be increased by three times, however, the color multiplexing brings about the possibility of crosstalk and noises in the acquisition process of the final image, incurring the decrease of bit-recognition rate. In order to improve the bit recognition rate, while keeping the storage capacity high, this paper proposes a new type of color QR code which uses the pattern information as well as the color information, and then analyzes how to increase the bit recognition rate. For this aim, the paper presents an efficient system which extracts embedded information from color QR code and then, through practical experiments, it is shown that the proposed color QR codes improves the bit recognition rate and are useful for commercial applications, compared to the conventional color codes.

Statement of problem: The color change of final restoration resulting from resin cement is variable since the amount of the tooth is prepared is minimum. Purpose: The purpose of this study was to compare the color accuracy of try-in paste and their corresponding resin cements and the color stability of restoration intermediated resin cement according to two shades of three products(Rely-X. Variolink II. Choice). Material and method: Color was measured for porcelain disk sample without try-in paste, and porcelain disk sample intermediated by try-in paste and resin cement, then color differences were calculated. Results : 1. Color difference(${\Delta}E^*$) between try-in paste and resin cement showed the lowest value at Variolink II and increased in the order Choice and Rely-X statistically significant, and $?E^*$ of three resin cements was greater in A3 then A1. 2. The values of ${\Delta}L^*$ and ${\Delta}a^*$ between try-in paste and resin cement was in the increasing order of Variolink II, Choice and Rely-X. The ${\Delta}b^*$ value was increased in this order Choice, Rely-X and Variolink II in A1 on the other hand Variolink II, Rely-X and Choice in A3. 3. Color difference(${\Delta}E^*$) before and after resin cement showed the lowest value at Variolink II and increased in the order Rely-X and Choice. Conclusion : Above result revealed that the colors of try-in paste and resin cement were more or less accurate in the range of 0.35-1.95 of color difference which was unnoticeable with human eye, and Variolink II was superior to the other resin cements in color accuracy.

Steampunk is a term generally used for one of the S. F. subgenre in literature, arts, fashion styles, and lifestyles. This study clarifies formative characteristics as well as the meanings of steampunk fashion style based on its attributes in movies and animations. Attributes of the steampunk are blending time, blending technology, and introspection against science development. In order to have an objective research, this study researched frequency of the fashion item, color, accessory of the collected fashion image, and after interpreted that consequence. Men's steampunk fashion was composed of men's basic outfit such as shirts, vest, jacket, pants, and coats of the 19th century. Black color took up the largest proportion for color. In accessory, top hat, goggle, and steam-powered weapons, in order, were most commonly used. Women's steampunk fashion was composed of shirts and long one-piece dresses, long skirt simply applied 19th victorian style fashion. Yellow, brown, and black color took up the largest proportion of fashion color. In accessory, top hat, belt trimming, corset, and boots, in order, were most commonly used. It is the characteristics of the steampunk fashion that represents retro-future fashion, as it features steam-powered mechanic esthetics, a kind of DIY subculture and transcending division of nationality, class, and gender.

This paper deals with contrastive analysis and interlanguage with respect to adjective ordering. It aimed to investigate how similar and different the orders of descriptive adjectives are in English and Korean, and how Korean EFL learners perceive the sequences of English descriptive adjectives. Data were collected from native English speakers and native Korean speakers and Korean EFL learners. The contrastive analysis showed that the order of English adjectives was size, opinion, condition, age, color, shape, material, and origin, whereas the Korean order was condition, age, opinion, color, size, shape, material, and origin. The relative order of the interlanguage was shown to be age, size, opinion, shape, condition, color, origin, and material, with the exceptions of the order of condition preceding age and that of size being the same position as condition. The interlanguage data manifested different aspects of ordering when compared with English and Korean: Some adjective combinations were similar to both English and Korean; Some were different from English or Korean; Some were different from both English and Korean. These ordering patterns are discussed in terms of such principles as the nouniness principle, the subjectivity/objectivity principle, the iconic principle, etc. On the basis of these results, some helpful suggestions are made.

This paper describes a new algorithm for pixel-based skin color detection to differentiate human form in color images by the ratio of R to H. In order to detect skin color efficiently, we examine the distribution of the R, G and B color elements combining to constitute the skin color in various color images. It shows that R is located in a narrower area than G and B on the RGB color space. And skin color is more related to R than G and B. Meanwhile, when the color image is transformed to the HSI color space, the S is variously changed in accordance with skin colors. The I is changed in accordance with the quantity and angle of light. But the H is less influenced by other conditions except for color. On the basis of the aforementioned study, we propose that the threshold for skin color detection is decided by the ratio of R to H. The proposed method narrows down the range of threshold, detects more skin color and reduces mis-detection of skin color in comparison to detection by R or H. In experimentation. it shows that the proposed algorithm overcomes changes of brightness and color to detect skin color in color images.
