This study aimed to create a new costume design suitable for publicizing our traditional patterns in the world by using the traditional patterns of Northeast Asia region. The result of this study can be summarized as follows. First, China is characterized by a strictly fixed configuration and a realistic description, Japan a simplistic modality and an abstract-geometrical pattern, and Korea a eclectic type, whole-pattern, and part-pattern. This study aimed to make the pattern by using harmoniously these characters. Second, Korea, China, and japan have many similarities concerning a symbolism and a type of pattern. In the modern fashion, they often use dragon patterns, various flower patterns like peony, plum blossom, or mum, and geometrical patterns. This study focused on expressing patterns which contain the ornamental symbolism of Oriental Look, aside from an existing symbolism, and show a traditional sentiment of Northeast Asia. The method for expressing traditional patterns usually included weaving, dyeing, embroidery, or gold foil. Although these methods have been used in all the three nations, even rubbed metal foil and patchwork have been widely used in Japan.

The shape of floral Pattern in the Period of Baroque could be divided single. bunch and vine. The style of representation was stylized, abstract and realistic. the most of style was stylized. The type of composition was fullness, independent and scattered. Floral patterns were shaped simple and complex and components of design could be classified into flower and leaf. flower and fruit. flower and band. bunch of flower, flower and geometry. flower and pot, flower and animal. flower and crest. Kinds of flower were tulip. common marigold, lily, carnation, small bel]flower. lotus, acandus leaf, pomegranate, strawberry. pine cone and abstract anonymous flower which were unfolded by repeat. Characters of floral Pattern were classical elegance, taste of royalty and lively and damask, velvet, brocade which made with gold and silver so, those were a very brilliant and gorgeous. Characters of design were illustrated plane style and stylization where developed arranged on front by repeat or repeat symmetric of vertical. Art, costumes and textiles in this era were a very rich and colorful. The result of study on Baroque's floral pattern will be used to develope a various textile design and chance to be adopted classical pattern into aesthetic value in our time.

In this paper, we design a secant pattern antenna combined with a septum circular polarizer to be used in the satellite data communications. To generate a radiation pattern with secant type, Fourier relationship between current distribution and space factor is applied and the circular symmetric structure of the aperture simplifies the design. The optimization process is performed by combining the radiator with the septum circular polarizer, and it is confirmed that the designed radiation pattern, axial ratio, and return loss characteristics satisfies the required performance of the antenna.

This paper suggests a implements and a design of class diagram authorization tool based on the MVC pattern. It defines and descries the structure of ClassInformation, ScreenDisplay and ToolManager. ClassInformation is responsible for processing or handling information of a diagram. ScreenDisplay is responsible for GUI to configure the screen of the authorization tool. ToolManager is responsible for event handling to process I/O of the authorization tool. Based on MVC pattern, ClassInformation, ScreenDisplay and ToolManager of the authorization tool are assigned each role independently. It is flexible to new requirement, because of loose coupling.

One of the major factors affecting maneuverability of an athlete is frictional force caused at an outsole of his shoe. The magnitude of the frictional force is closely related to pattern and hardness of outsole and roughness of ground or floor. This study then focuses on the effect of outsole pattern of sports shoes on the frictional force. After surveying outsole patterns of sports shoes in markets, we select 4 types of outsole patterns, such as straight, W, O, and wave as primary outsole patterns of sports shoe and we also select depth, pitch and slope as design parameters of each pattern. Corresponding to those patterns and design parameters, various outsole specimen are prepared for frictional experiments. After performing frictional tests with those specimen, coefficients of friction(COF) are collected and analyzed with a statistical tool to draw useful conclusion.

This study reviews the process of creating the patterns through the Christopher Alexander's books to discover the fundamental rules for creation of the pattern language. The essential ideas of 11 rules describing the characteristics of the pattern language are organized by keyword depending on the characteristics of each rule. Then, this study analyzes which keyword was applied importantly and how it had been developed chronologically in the Alexander's books. As a result, 5 keywords - reflection of cultural difference, reflection of human desires, solving the repeated problem, function suitable for principal purpose, and network structure - are applied to his early books in which the pattern language was theoretically developed, the pattern of traditional society was discovered and the network structure was developed. Another 5 keywords - user participation method, new problem solving, structure preserving transformation, post-mechanization method, and central invariant structure - are applied to the books in his mid-term after completion of the pattern theory which discover new pattern for contemporary society and apply the pattern language to time and space. In his later books which organize the theory of pattern language and suggest the direction for using the pattern language, 5 keywords - wholeness, post-mechanization method, user participation method, new problem solving, and structure preserving transformation - are applied. Users may use the pattern language more precisely if he/she considers the keywords of the early period in searching the patterns of existing environment, the keywords of the intermediate period in searching the patterns of new environment or in regard to time and space, and the keywords of the later period in considering direction of the application of the pattern language.

In the maskless photolithography based on the Digital Micromirror Device (DMD) by Texas Instruments Inc. (TI), the micromirror array works as a virtual photomask to write patterns directly onto Flat Panel Display (FPD) at high speed with low cost. However, it is neither simple to generate region-based patterns for the micromirror array nor easy to deliver sequences of patterns for the micromirror controller. Moreover, the quality of lithography yields the precise synchronization between generating sequence of patterns and irradiation rate off micromirrors. In this study, the region-based pattern generating system for maskless photolithography is devised. To verify salient features of devised functionalities, the prototype system is implemented and the system is evaluated with actual DMD based photolithography. The results show that proposed pattern generating method is proper and reliable. Moreover, the devised region-based pattern generating system is robust and precise enough to handle any possible user specified mandate and to achieve the quality of photolithography required by FPD manufacturer.

This work presents a method of optimum design for reinforced concrete building frames with rectangular cross sections. To overcome difficulties arising from the presence of two materials in one element(concrete and steel) , the principle of divided parameters is adopted. The design variable parameters are divided into two groups - external and internal. The optimization is also divided into external and internal procedure. Several scarxh algorithms are tested to verify their accuracy for the external optimization. This work proposes a new search method, a modified pattern search, and sample problems prove its accuracy and uscf'ulness. The design obtained by this method is an optimum and in full accord with ACI Building Code Ftequirements(ACI'318-89).
