  • Patterns are something that comes out of necessity in human life, which is closely associated with it. Thus come the SFAA (Seoul Fashion Artists Association) collection which uses patterns varying in form, color, way of expression and material. For this research, I first categorized the patterns the SFAA designers used into: natural patterns, symmetric patterns, traditional patterns, stripe, plaid, dot and abstract patterns. As a result of the process. the designers most favored the natural patterns and symmetric patterns, and dot patterns were rarely used. The designer who most favored patterns in general was Sul Yun-hyoung, and the designer Kim Chul-ung rarely favored the surface effect. The seven kinds of patterns naturally differ according to the designer. as Park Hang-chi liked to use the plaid patterns along with yam dyeing material, whereas Jin Teok expressed stripe patterns using the yarn dyeing fabric. Natural patters were presented in a bizarre way with Lie Sang-bong. who took the motives appearing in Eastern ceramic and paintings into the clothes, using the print method. The symmetric patterns, which the SFAA designers most preferred. was used evenly among designers like Chang Kwang-hyo, Gee Choon-hee. Rubina, and Haneza. In contrast. Lie Sang-bong. who used abstract patterns that do not give out meaning of the actual form of the pattern. rarely used symmetric patterns. The dot patterns were most often used by Park Youn-soo. and traditional patterns were overwhelmingly chosen by Sul Yun-hyoung. Secondly. in expressing the colors, SFAA designers were much more likely to choose achromatic colors. not choosing to show off colors. This is especially apparent in works by Haneza and Lie Sang-bong. In the SFAA collections, numerous methods were used to create. For instance, Sul Yun-hyoung used the oriental embroidery method. and Rubina and Lie Sang-bong used many unique dying methods. In terms of materials, Sul Yun-hyoung preferred silk. due to her methods, and Lie Sang-bong was one of the designers that used a number of different materials such as vinyl. Jacques Mueclier of the Paris Clothes Association in France, who was invited to SFAA collection once, remarked. "While the choice of material and the actual sewing done were excellent, there lacked much difference among the designers, as most of them choose flowing silhouette In terms of composition," which is all too correct. In addition, there were cases in the collection where the inherent feelings of cultural artifacts was expressed without alteration. Summing up, the research aimed to analyze the surface expression methods, forms and color of SFAA designs. and I hope that it can open up ways for new projects in the future.he future.

  • This study analyzes interrelationship with air pollution quality and land use patterns using GIS. The relationship can be obtained via three steps: (1) making out air pollution map from air pollution information of study area, (2) dividing land use patterns into residential area, commercial area, industrial area, traffic concentrated area, and non-polluted area, and (3) spatial overlaying analysis of GIS. Moreover, through analyzing air pollution quality by land use patterns, pollution sources can be identified. The results also coincide with the characteristics of conventional air pollution finding. More detailed analyses using articulated on site air pollution quality measurement databases are needed to correctly identify the pollution sources through finding interrelationship with land use patterns and air pollution Quality using GIS. The developed method can help trace the path of pollution sources and plan urban land use projects.

  • This study demonstrates the process of fabricating patterns using tribonanolithography (TNL),with laboratory-made micro polycrystalline diamond (PCD) tools that are attached to an atomic force microscope (AFM). The various patterns are easily fabricated using mechanical scratching, under various normal loads, using the PCD tool on single crystal silicon, which is the master mold for replication in this study. Then, polydimethylsiloxane (PDMS) replica molds are fabricated using precise pattern transfer processes. The transferred patterns show high dimensional accuracy as compared with those of TNL-processed silicon micro molds. TNL can reduce the need for high cost and complicated apparatuses required for conventional lithography methods. TNL shows great potential in that it allows for the rapid fabrication of duplicated patterns through simple mechanical micromachining on brittle sample surfaces.

  • In this paper, we proposed an algorithm to detect aggressive driving status by analysing six kinds of driving patterns, which was achieved by comparing for the feature vectors using mahalanobis distance. The first step is to construct feature matrix of $6{\times}2$ size using frequency response of the time-series accelerometer data. Singular value decomposition makes it possible to find the dominant eigenvalue and its corresponding eigenvector. We use the eigenvector as the feature vector of the driving pattern. We conducted real experiments using three drivers to see the effects of recognition. Although there exists differences from individual drivers, we showed that driving patterns can be recognized with about 80% accuracy. Further research topics will include the development of aggressive driving warning system by improving the proposed technique and combining with post-processing of accelerometer signals.

  • The DGA (Dissolved Gases Analysis) technique has been widely using for fault diagnosis of the power transformers. Some electric power utility company establishes the criteria of DGA to improve reliability, because of difference of operation environment and design of power transformer. In this paper, we introduce intelligent diagnosis system for DGA result of KEPCO (Korea Electric Power Cooperation). This system can classify patterns type of gases ratio that frequently occurs in recent result of gases analysis using Fuzzy Inference. The classification of Patterns let us know that major causes of gases generation based on type of patterns. Finally, Neural Network based on patterns diagnose transformer. NN was trained using result data of DGA of actually faulted transformers recently. Result of intelligent diagnosis system is right well in comparison with actual inner inspection of transformers.

  • In order to convey exactly what a work is intended to project, it is necessary to select appropriate materials, those whose features are suitable for the work to be accomplished. Among the recent trends in dyeing involve the use of the designers' own techniques and a variety of materials, as well as the designers' efforts at promoting the value of plastic art. According I choose splendid butterfly patterns that diversity in shape and color, among nature patterns offer unlimited imaginative power. I designed the fabric pattern, using tie dyeing, cone dyeing, transfer dyeing and rub dyeing that can best express my intentions. Therefore a total of four works were designed with aesthetically appealing revised shapes of a butterfly, using materials developed using the same method, to suggest the possibility of creating a new design while maintaining the original beauty of plastic art.

  • The contemporary shoes have been progressively trying a variety of designs using patterns as well as the formative change. However, for making those patterns secure the continuing values as the design having global competitiveness without being a temporal trend, it is required to develop the patterns which reflect the unique identity of Korea. Such development can be realized through the analysis on the traditional patterns of Korea. The patterns are the symbol of collective values. The traditional patterns implicitly express the philosophical thinking of members in a society as having been inherited up to now. Thus, this paper analyzed the gilt bronze shoes in Three Kingdoms Era using the patterns as unique design elements among traditional shoes of Korea. The symbolism of those patterns was expressed as transcendence of time and space, harmony of spirit and materials, and convergence of a region and religion. On the aspect that our ancestors interpreted and overcame the bounds of nature around human beings, pursued the ideal beyond reality and accepted a variety of thoughts, it is considered that the patterns used in gilt bronze shoes expressed anthropocentricism, idealism and inclusivism.

  • In this paper, we have investigated a selective assembly method of single-walled carbon nanotubes (SWCNTs) on a silicon substrate using only photolithographic process and then proposed a fabrication method of field effect transistors (FETs) using SWCNT-based patterns. The aminopropylethoxysilane (APTES) patterns, which are formed for positively charged surface molecular patterns, are utilized to assemble and align millions of SWCNTs and we can more effectively assemble on a silicon (Si) surface using this method than assembly processes using only the 1-octadecyltrichlorosilane (OTS). We investigated a selective assembly method of SWCNTs on a Si surface using surface-programmed APTES and OTS patterns and then a fabrication method of FETs. photoresist(PR) patterns were made using photolithographic process on the silicon dioxide (SiO2) grown Si substrate and the substrate was placed in the OTS solution (1:500 v/v in anhydrous hexane) to cover the bare SiO2 regions. After removing the PR, the substrate was placed in APTES solution to backfill the remaining SiO2 area. This surface-programmed substrate was placed into a SWCNT solution dispersed in dichlorobenzene. SWCNTs were attracted toward the positively charged molecular regions, and aligned along the APTES patterns. On the contrary, SWCNT were not assembled on the OTS patterns. In this process, positively charged surface molecular patterns are utilized to direct the assembly of negatively charged SWCNT on SiO2. As a result, the selectively assembled SWCNT channels can be obtained between two electrodes(source and drain electrodes). Finally, we can successfully fabricate SWCNT-based multi-channel FETs by using our self-assembled monolayer method.

  • The author distributed the questionaires which ask the idea of the purchase of children's clothes in order to help the emotinal development of children and to raise demostic economy. 89% of those who answered realized the necessity of home sewing. Because of the lack of sewing ability(66%), the author made comparatively easy patterns such as blouses for summer, skirts, short pants and one-piece dresses. To populrize these patterns, the aother used the measurements of body-measurement which were made by Korea Institute of Standard. The author studied the patterns and choice of patterns according to growing body. The author tested the clothes worn and visual evaluation for fitness of the patterns. The results are as follows: First; The author developed basic pattern 1 and 2 and applied to design A, B and C. Second: For every design, the author made patterns fit to the children. Third: According to age, the author curtailed or enlarged patterns. Lastly: The author tried to reduce living expenses through making children's clothes using the sewing machine and supress over-consumption and lead the people toward normal economic life.
