This study selects camellia flowers as a material for design development and created patterns by simplifying the image of camellia flowers and combining it with a geometrical motif. It it applied them to various fields to develop design content for fashion cultural products that were Korean, modern, and competitive. For this purpose, this paper used Adobe Illustrator CS2 to turn the camellia flower into a motif and develop it into a pattern. Based on the realistic form of camellia flower, this paper set 3 basic motifs of new formative images, using graphic elements, such as omission of a form, simplification, overlapping, repetition, and reduction, and it also developed two transformed motifs by applying a different color to each motif. This paper repetitively arranged each motif in the background of a diamond shape, a square, and a circle, and it combined each motif with the patterns of marcel, stairs, and stripes, through which it expressed the combination of the geometrical patterns and the flower patterns. Through the application of repetitive and combined patterns of each motif, the enlargement and reduction of motifs, the repetition of motifs, the combined use of motifs, and the change in colors and layout, this paper used the motifs of various fashion cultural products, such as scarves, neckties, and T-shirts.

For the Gwangyang Ume Flower Festival, this study sought to develop competitive fashion culture goods design and to activate regional culture festival by reinterpreting ume flower image in accordance with current trends, manufacturing motive patterns, and applying them to neckties, scarves, and T-shirts. In terms of method, four basic motives were set that showed new figurative images of ume flowers using Adobe Illustrator 10. The repetitive units of each motive we combined with the ume flower motives and the geometrical patterns, such as quadrangle, triangle, and circle. The basic direction of design was set so that color and texture could have colorful, modern, and natural images using pastel tone and gradation. The set patterns were applied to the repetition, the repetition of the transformed patterns of 45 angle, and the strife patterns, making it possible to display various images in the fashion items such as neckties, scarves, handkerchiefs, or T-shirts. The development of such fashion culture goods seems to be more significant, since they can be easily accessed by general festival participants. Accordingly, the Gwangyang Ume Flower Festival seems to develop not into food-led festival, but into a cultural festival that can publicize more various programs and create profits.

Men's outer wear, such as jackets and coats appeared since the 16th century. They have been changed from doublets, coats, justaucorps, tail-coats, frock coats and morning coats to contemporary men's suits. Since the early 17th century, sleeve patterns of men's outer jackets had been mostly two-pieces close fitted patterns. The purpose of this article is to compare sleeve patterns of various jackets, which appear in various historic costume books. Armhole measurements, sleeve head measurements, amounts of ease, armhole depths, armhole widths, crown heights, sleeve width and sleeve angle had been compared to find out the differences among patterns of different times and styles. Coming to the present, the difference between top sleeve and under sleeve became more obvious, and the sleeve angle became less curvy. Another interesting point is that there had been considerable amounts of ease, which is the difference between sleeve head measurements and corresponding armhole measurements. It is because the sleeve has been attached to the armhole not by seam but by string. It is believed that the present sleeves have more natural curve and shape compared to the past.

Maximum power point tracking (MPPT) under the partial shading condition is a challenging research topic for photovoltaic systems. Shaded photo-voltaic module result in complex peak patterns on the power versus voltage curve which can misguide classical MPPT algorithms. Thus, various kinds of global MPPT algorithms have been studied. These have typically consisted of partial shading detection, global peak search and MPPT. The conventional partial shading detection algorithm aims to detect all of the occurrences of partial shading. This results in excessive execution of global peak searches and discontinuous operation of the MPPT. This in turn, reduces the achievable power for the PV module. Based on a theoretical investigation of power verse voltage curve patterns under various partial shading conditions, it is realized that not all the occurrences of partial shadings require a global peak search. Thus, an intelligent partial shading detection algorithm that provides exact identification of global peak search necessity is essential for the efficient utilization of solar energy resources. This paper presents a new partial shading determinant algorithm utilizing adaptive threshold levels. Conventional methods tend to be too sensitive to sharp shading patterns but insensitive to smooth patterns. However, the proposed algorithm always shows superb performance, regardless of the partial shading patterns.

With the recent proliferation of Hallyu content, national interest in Korea and the demand for designs with traditional Korean patterns as a motif is on the rise. In addition, as customers' design requirements tend to value more and more detailed and differentiated handcrafted designs, research on the motifs used in nail experts' original nail design development and nail design is continuously needed. Therefore, the purpose of this study is to expand the scope of nail design motifs with high practical value by producing nail design works applying plant patterns of Wadang, used during the Unified Silla Period, and to diversify nail art expression techniques. The research reviewed domestic and foreign literature related to Wadang during the Unified Silla Period, analyzed the collection at the National Museum of Korea, and categorized the motifs based on the characteristics of plant patterns and Wadang during the Unified Silla Period. The tangible motifs are intended to be presented as a fusion of nail art design works that utilizes both flat and stereoscopic art techniques. Through this study, it was confirmed that the plant pattern of Wadang from the Unified Silla Period is an attractive motif that can be expressed in various nail designs expressing Korean emotions and traditional beauty, and furthermore, it can be used as basic data for the idea of various beauty design areas.

This study was analyzed three basic patterns of the Islamic arts. These are natural flora, geometrical and calligraphy pattern. Islamic belief in Aniconism, doctrine of unity and worship of arabic language demanded delicate, decorative, and abstract patterns instead of patterns of real image. Natural flora pattern was classified into arabesque and various flower patterns. Muhammad commands that "The artist who fashions a representation of living things is competitor of God and therefore destined to eternal damnation, so if you want to represent living things, you should only depict flowers and trees". Then the natural flora patterns developed into main Islamic pattern. Geometric pattern was composed of geometrical elements like, circle, trigon, square, rectangle, pentagon, hexagon, octagon or other polygons, stars or motifs with straight or curved lines. Circle symbolized ′celestial′ sphere and crystal of the lower octagon symbolized ′earthly existence′. Therefore if the circle join with the octagons, it means fusion of celestial and earthly existence. Another important influence on the Islamic art was the calligraphy pattern, the writing of Arabic language. The major language of calligraphy pattern was Arabic script and often Persian script. Calligraphy pattern was composed of Kufic and Cursive script. The cursive script was developed various forms. The Islamic tenet prohibit depiction of sacred images, the sacred Arabic calligraphy such as ′Alla′ or ′Mohammad′ was substituted of them. And the content of calligraphy pattern was used with Quranic phrases. The aesthetics of Islamic patterns analyzed aesthetic of ′rhythmic lines′, aesthetic of ′unity in multiplicity′, aesthetic of tessellation and aesthetic of harmony. On the textiles of the Islamic culture, the arabesque, floral, geometric and calligraphy patterns were frequently used.

After the beginning of Web2.0 era, newly developed interaction design patterns based on Ajax(Asynchronous JavaScript and XML) have been tried in various Web2.0 services. These new interaction design patterns enable web service to provide rich experience for users. However, it is very hard to find organized task based guideline about Web2.0 interaction design even though there are a lot of complicated interaction design techniques and patterns. It is essential to have Web2.0 interaction guide based on Ajax because it can guide designers to use appropriate interaction design patterns and to keep usability for ordinary users. Therefore, this research aims to establish task based interaction design guideline for Web2.0 service based on Ajax. The reason why this research focused on Ajax is that Ajax is most widely used language for Web2.0 service. First, primary five interaction design patterns were defined through analysis of various interaction design patterns from Web2.0 services. Second, detail interaction design tasks from five major patterns were analyzed based on the study of major Web2.0 services such as Gmail, Twitter, YouTube and Google maps. Third, general design guidelines such as heuristic guidelines for web service are studied through literature review. After all, this study proposed task based interaction design guide for Web2.0 service with Ajax. With this guide, designers and developers can choose appropriate Web2.0 interaction patterns and apply to their service and provide service to users with enhanced usability and satisfaction.

This thesis has three main purposes: first, will show kinds, patterns, types, expression techniques of modern korean women's trimmings by every ten years. Second, it is to trace the effect of each decade on women's Hanbok trimming designs. Third, it will point out factors. that caused the change of modern Korean women's Hanbok trimming design patterns. Henceforth, there comes the result of the research and analysis. Trimming design patterns of modern women's Hanbok can be divided into three categories temporally: The first period of from 1910s to the first half of 1950s saw that design patterns did not changed much from traditional ones. It is because there were many catastrophes such as the invasion of Japanese Empire and Korean War. The compound design had expressed people's wish to earn many sons and babies at the end of Joseon Dynasty. But it turned to wishing luck for individuals affected by individualism and liberalism imported from the west. Realistic designs are the most frequently used and the least lines made up patterns. The second period of from the latter half of 1950s to 1970s saw that women wore their Jeogories and Chimas as suits. Screen printing technique enabled for various design patterns to come out. And the development of textile industry introduced various expression techniques such as making lace, meshing, flocking, burn-out etc cetera. The third period of 1980s saw that Hanbok became a kind of luxurious clothe as people's living standard rose. Hanbok again came into the spotlight, Hanbok designers came forward and their individualities are respected. The characteristic expression technique of grey-dying and geometric design patterns are more frequently used for the simple and modern beauty.

Recently, many large organizations have multiple data sources (MDS') distributed over different branches of an interstate company. Local patterns analysis has become an effective strategy for MDS mining in national and international organizations. It consists of mining different datasets in order to obtain frequent patterns, which are forwarded to a centralized place for global pattern analysis. Various synthesizing models [2,3,4,5,6,7,8,26] have been proposed to build global patterns from the forwarded patterns. It is desired that the synthesized rules from such forwarded patterns must closely match with the mono-mining results (i.e., the results that would be obtained if all of the databases are put together and mining has been done). When the pattern is present in the site, but fails to satisfy the minimum support threshold value, it is not allowed to take part in the pattern synthesizing process. Therefore, this process can lose some interesting patterns, which can help the decider to make the right decision. In such situations we propose the application of a probabilistic model in the synthesizing process. An adequate choice for a probabilistic model can improve the quality of patterns that have been discovered. In this paper, we perform a comprehensive study on various probabilistic models that can be applied in the synthesizing process and we choose and improve one of them that works to ameliorate the synthesizing results. Finally, some experiments are presented in public database in order to improve the efficiency of our proposed synthesizing method.

In this paper, experimental methods about the flow behavior of thin polymer film by various edge patterns in the spin coating process for stable cover layer coating of a blu-ray disc is described. The blu-ray disc, a next-generation optical disc format over 25GB, consists of a 1.1m thick substrate and a 0.1mm tick cover layer. Generally, cover layer on the blu-ray disc is made by the polymer spin coating process. However, it is hard to secure sufficient coating uniformity around the rim on the cover layer. In order to get the uniform thickness deviation and to minimize the bead around the rim, the edge of the disc substrate can be modified into various patterns, such as normal plain, trench, step and chamfer pattern, etc, around the rim on the disc and experimented with various parameters, such as surface tension, viscosity, coating time, temperature and rotation speed, etc. And the optimal shape of the rim was tried to get by 3 dimensional computer simulation of the polymer expulsion process.
