Nowadays, urbanized area expands its boundary, and distribution of urbanized area is gradually transformed into more complicated pattern. In Korea, SMA(Seoul Metropolitan Area) has outstanding urbanized area since 1950s. But it is ambiguous whether urban distribution is clustered or dispersed. This study aims to show the way in which expansion of urbanized area impacts on spatial distribution pattern of urbanized area. We use quadrat analysis, nearest-neighbor analysis and fractal analysis to know distribution pattern of urbanized area in time-series urban growth. The quadrat analysis indicates that distribution pattern of urbanized area is clustered but the cohesion is gradually weakened. And the nearest-neighbor analysis shows that point patterns are changed that urbanized area distribution pattern is progressively changed from clustered pattern into dispersed pattern. The fractal dimension analysis shows that 1972's distribution dimension is 1.428 and 2000's dimension is 1.777. Therefore, as time goes by, the complexity of urbanized area is more increased through the years. As a result, we can show that the cohesion of the urbanized area is weakened and complicated.

This study improves the fitness of Air Force winter service uniforms through the development of a shirt pattern drafting method and automatic pattern drafting program for MTM production. A calculation formula is formed through a correlation analysis and regression analysis using Size Korea 2004 3D measurement data after analyzing 4 kinds of existing shirt pattern drafting methods and 3 types of shirt patterns currently used for the Air Force service uniform. The results of this study are as follows: The developed pattern drafting method has 4 parts that use calculated dimensions: neck base width, front interscye, back interscye and scye depth. Other body measuring parts that have a high correlation with calculation parts are inserted into regression analysis as independent variables to create dimension calculation formulas. The result of the final study patterns were better than existing winter service uniforms in nearly all items for the appearance evaluation and motion adaptability evaluations. The method was converted into an automatic pattern drafting program using C++ after the completion of pattern drafting method development.

in this paper, we imlemented design pattern retrieval system for efficient managemant and reusability of design patterns. Pattern is conssisted of property information and meta information id used for similarity measurement on classification and retrieval of patterns.Meta information od used for UML modeling of patterns. We classified design patterns with the empirical scope in addition to Gamma's basic classification. also we used E-SARM for retrieval represented UML diagram with pattern meta information, and simulated the environment so as to obtain best result on applying to retrieval of design pattern. This system is able ro resister new patterns through pattern viewer and manages these patterns with property informaiton and meta information. Thus this system supports efficient management of patterns, UML modeling, priority pattern retrieval, higher reusability and reduces pattern selection cost.

Hwa-byung is a form of psychogenic illness among people in Korea and is listed as a culture-bound syndrome of Korea in the DSM-IV. Despite increased clinical researches for Hwa-byung in the oriental medicine of Korea, there has been no agreement of pattern identification for Hwa-byung. The purpose of this study is to develop a standard instrument of pattern identification for Hwa-byung which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 15 neuropsychiatry professors of 11 oriental medical colleges nationwide. The experts attended 2 consultation meetings and discussed developing the instrument. and we also took professional advices by e-mail. The results were as follows; First, we divided the symptoms and signs of Hwa-byung into five pattern identification - stagnation of liver Qi, flare-up of the liver fire, disharmony between heart and kidney, deficiency of both Qi and blood, malfunction of gallbladder due to phlegm stagnation. Second, we got the mean weights to each symptom of five pattern identification which had been scored on a 5-point scale - ranging from 0 to 4 by the 15 experts. Third, we made out the Korean instrument of the pattern identification for Hwa-byung. It was composed of 34 questions and decided on question-and-answer form. Though there are some limits in this study, the instrument of pattern identification for Hwa-byung is meaningful and expected to be applied to the subsequent research. And also, we hope to improve the instrument and make up for this study through various research and discussion.

This study aims to reveal understanding of general users on pattern identification questionnaire items from published papers. 132 questionnaire items were selected from five papers which studied reliability and validity of survey items for pattern identification. 36 general participants answered understanding degree on each items, 11 experts also responded clinical utilizability on these. 6 questionnaire items had different recognition between general participants and experts, which were well used items to diagnose for experts, not easily understood to general participants. This study is the first work to analyze pattern identification's item understanding of general participants. Diversified subject population should be involved in further studies for assessment of general participants' understanding degree of questionnaire items.

The light guide plate (LGP) of LCD-BLU (Liquid Crystal Display-Back Light Unit) is usually manufactured by forming numerous dots by etching process. However, the surface of those etched dots of LGP is very rough due to the characteristics of etching process, so that its light loss is relatively high due to the dispersion of light. Accordingly, there is a limit in raising the luminance of LCD-BLU. In order to overcome the limit of current etched-dot patterned LGP, micro-lens pattern was tested to investigate the possibility of replacing etched pattern in the present study. The micro-lens pattern fabricated by the modified LiGA with thermal reflow process was applied to the optical design of LGP. The attention was paid to the effects of different optical pattern type (i.e. etched dot, micro-lens). Finally, the micro-lens patterned LGP showed better optical qualities than the one made by the etched-dot patterned LGP in luminance.

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 study uses two numerical approaches to analyze the filling behavior of micro patterns on micro-injection molding for V-grooves pattern which cannot be simulated with conventional CAE packages. The parametric studies have been performed to examine the fidelity of micro patterns with respect to temperature, pressure, inlet velocity and pattern location on the mold according to the boundary condition from the macro pressure and velocity data which can be obtained by conventional CAE packages. Through these numerical approaches, the filling behavior of polymer melt in micro patterns can be understood, the quality of replication can be predicted, and the V-groove pattern can be shaped uniformly during the process of injection molding.

This study is to review the development of calico printing pattern design for fabric through historical perspective. Calico is a cotton cloth named from Calicut, a city of India. It was first brought to England by the East India company in 1621. Although the name is generally given and plain white cotton cloth, and in America it is applied to small-scale printed cottons, today it applies to indian cotton cloth, coarse or fine, woven with colored geometrical large-scale and small-scale patterns, painted or printed. Therefore this paper proposes the classification and feature extraction of calico printing pattern from the early of 16th century to 21th century. The results of this study can be effectively applied to develop competitive calico pattern design in domestic cotton textile industry.
