This study proposes 3D printed shoe designs with patterns made by reinterpreting traditional Korean muntin patterns as customized designs that are unique to individual consumers and different from existing products. In the fashion industry, shoes with diverse designs grafted with 3D printing technology have been introduced. Artistic 3D printed shoes showcase the unique designs of designers. Functional and practical 3D printed shoes that can be worn during daily activities and during exercise have been actively developed. Traditional Korean pattern designs are also being recreated into designs reflecting the aesthetic sense of modern times with our own identity. The uniqueness of the traditional muntin patterns in geometric shapes, such as intersections of lines, rectangles, and octagons, are expressed in shoe designs with modern aesthetic senses by utilizing the traditional patterns that conform well to the modern geometric beauty of forms. This study was intended to develop 3D shoe designs that reinterpreted the motif of muntin patterns from among traditional Korean geometric patterns with a modern aesthetic sense. The octagonal patterns that express the scenery of spring can be seen through the muntins in traditional Korean-style houses were designed on the heels of shoes. Utilizing the Rhino CAD program and ProJet 660 Pro 3D printer, shoes were designed and printed. The processes for making shoes using 3D printing technology proposed in this study are significant because they represent the creation of designs in a new area. The results of this study might help in the development of 3D printed fashion products.

The purpose of this study is to testify the pattern making method to develop the men's basic bodice pattern using 3-dimensional body scan data. The experimental patterns were made by adding wearing ease on flattened body scan data and tracing the outlines of it. The experimental bodice pattern were composed of front, back, and side panels. To compare the difference between the experimental pattern and traditional pattern, two pattern making methods were compared. Two sets of basic bodice patterns were made for each of the 10 male subjects: a set of pattern was made by experimental method and the other set was made by Bunka pattern making method. The experimental and traditional patterns were measured at 13 dimensions. The results show that there was a difference between the experimental patterns and traditional patterns at the front length, back length, front width, front neck width, back neck width, and back neck depth. The fit was also compared for both patterns. The results of the fit test show that the experimental patterns were superior to the traditional patterns at the fit of neck, shoulder, and armhole. The experimental pattern making method was expected to be useful for mass customization.

This study aims to suggest a bag design focusing on the symbol of Bo patterns by developing a pattern-based textile which forms a Korean design with a modern sense of beauty as well as following the conventions of traditional cultures, a design which is based on the previous study on formative characteristics of Bo patterns. That is, seven pieces of motifs are considered as proper patterns that have a symbol suitable for the materials of bags, showing their individual beauty well. This includes Horomum (longevity and prosperity of desendants), Banjangmum (eternity and samsara), Jeonbomum (treasure and luck), Seobomum (innate good fortune), Bangseungmum (it means that things don't break in harmony with one another), Bomum (embroidered patches for royal family representing justice), and Seogakmum (blessed life). With these seven motifs, we developed textile patterns and printed them through DTP. Then, we created a fashion bag design with a high quality using durable canvas fabrics. Therefore, a fashion bag with the Bo patterns symbol has a propitious symbol designed with a propitious shape, not to mention its formative beauty. It is expected to have value as a fashion art item by being redesigned for benevolent patterns with a modern image.

We explored localized plasmonic field enhancements using nanowire patterns to improve the sensitivity of a surface plasmon resonance (SPR) sensor. Two different materials, gold and silver, were considered for sample materials. Gold and silver nanowire patterns were fabricated by electron beam lithography for experimental measurements. The wavelength SPR sensor was also designed for these experiments. The material-dependent field enhancements on nanowire patterns were first calculated based on Maxwell's equations. Resonance wavelength shifts were indicated as changes in the refractive index from 1.33 to 1.36. The SPR sensor with silver nanowire patterns showed a much larger resonance wavelength shift than the sensor with gold nanowire patterns, in good agreement with simulation results. These results suggest that silver nanowire patterns are more efficient than gold nanowire patterns, and could be used for sensitivity enhancements in situations where biocompatibility is not a consideration.

In textile industry, needs for various weave drafts have been increased to produce high qualified textile goods. One of disadvantages of traditional textile industry was spending time and money on manual sampling. Nowadays, however, weave draft design and sampling using CAD programs reduce these consumption efficiently. Therefore, this study aimed to provide high qualified woven fabrics by weave draft designs influenced by geometric patterns. First, We analyzed geometric patterns, except for dot, stripe, and checks, in fashion collections from 2009 to 2014 S/S. Then, based on these analyses, design concepts were decided. Third, weave drafts influenced by geometric patterns were designed with weave CAD program, TEX PRO 10.0 by Youngwoo CNI inc. Forth, We simulated fabrics woven by new drafts using CAD programs, depending on fibers, yarns, density of woven, colors, and finishes. Unclassified geometric patterns would be expressed by small size patterns that influenced by retro moods, square patterns with various color variation, zigzag lines, and pieces of puzzles. Three design concepts were decided as greenness, neoclassic, and romantic chic. Thus, geometric patterns for printing were created as drafts for general looms, and one repeat of each draft were provided. According to the design concepts, we designed 13 fabrics with 4 geometric patterns weaving drafts. All Drafts were designed with CAD programs. Finally, same drafts were simulated as woven fabrics for both S/S and F/W seasons by changing each element, such as fiber, yarns, density, colors, and finishes.

This study is about the strife patterns in modern fashion and the characteristics inherent in them. The study was aimed at offering the basic materials to develop the creative design that can show various visual expression effects. In terms of method, the study was led by the analysis of documents; domestic and foreign fashion, collection magazines etc were used to analyze the strife patterns in modern fashion. According to the findings, the study used the rearrangement of the strife patterns at the same intervals, the arrangement of different strife patterns within one single item, the hybrid arrangement of strife patterns and different patterns, and the use of strife patterns for a certain part of clothing for the purse of emphasis or decoration. First, the characteristics inherent in such strife patterns showed clear simplicity using the same repetition of simple lines or the two colors of black and white. Second, strife patterns changed silhouettes by causing optical illusion, and showed the rhythm effects, such as swelling, wave or movement by distorting and controlling lines or forms. Third, based on irregular intervals or multi-strife, the concept of unclear disharmony and inconsistency was shown with the beauty of hybridharmony by blending various strife patterns with each other, or strife patterns with different patterns, and thus expressing composite images.

A model that precisely forecasts how much wind power is generated is critical for making decisions on power generation and infrastructure updates. Existing studies have estimated wind power from wind speed using forecasting models such as ANFIS, SMO, k-NN, and ANN. This study applies a projected clustering technique to identify wind power patterns of wind turbines; profiles the resulting characteristics; and defines hourly and daily power patterns using wind power data collected over a year-long period. A wind power pattern prediction stage uses a time interval feature that is essential for producing representative patterns through a projected clustering technique along with the existing temperature and wind direction from the classifier input. During this stage, this feature is applied to the wind speed, which is the most significant input of a forecasting model. As the test results show, nine hourly power patterns and seven daily power patterns are produced with respect to the Korean wind turbines used in this study. As a result of forecasting the hourly and daily power patterns using the temperature, wind direction, and time interval features for the wind speed, the ANFIS and SMO models show an excellent performance.

Korean language has different structural properties which are controlled by semantic constraints of verbs. Also, most of Korean sentences are complex sentences which consisted of main clause and embedded clause. Therefore it is difficult to describe appropriate syntactic grammar or constraint for the Korean language and the Korean parsing causes various syntactic ambiguities. In this paper, we suggest how to describe CFG-based grammar using sentence patterns as syntactic constraint and solve syntactic ambiguities. To solve this, we classified 44 sentence patterns including complex sentences which have subordinate clause in Korean sentences and used it to reduce syntactic ambiguity. However, it is difficult to solve every syntactic ambiguity using the information of sentence patterns. So, we used semantic markers with semantic constraint. Semantic markers can be used to solve ambiguity by auxiliary particle or comitative case particle.

In this paper, Experience Sensitive Cumulative Neural Network (ESCNN) is introduced, which can cumulate the same or similar experiences. As the same or similar training patterns are cumulated in the network, the system recognize more important information in the training patterns. The functions of forgetting less important informations and attending more important informations resided in the training patterns are surveyed and implemented by simulations. The system behaves well under the noisy circumstances due to its forgetting and/or attending properties, even in 50 percents noisy environments. This paper also describes the creation of the generalized patterns for the input training patterns.
