This is a study regarding the development of cultural products with applied traditional Saekdong-image. The objective of this study is to develop unique cultural products which combine traditional korean images with modern feel by utilizing traditional Saekdong-image. Saekdong has been an object of deep attachment and regarded as a tool for expressing korean images from ancient times to the present. Chosun dynasty shows a wonderful growth of fashion not only in dress but also in such accessories as patchwork wrapping-cloth and Saekdong, which imply a lot on formation or color arrangement. Approximately 24 pieces of cultural products that can be used in daily life were created using Saekdong, including traffic or credit card cases, name card cases, pouches, coin purses, bags, Vest, teapot wrapping-cloth, brooch. After design plans were made for each works, natural dyes were used to dye(dip dyeing) the fabrics(cotton, silk, linen) by theme. In addition, the increased quality of the products will be a competitive edge in the world market where products compete with no national bounds.

This study has been carried out to investigate the differences of compressional properties in various wool fabrics which have different structural conditions in composing ratio of wool fabric, count of material yarn and cloth count of fabric. The result of the study are summarized as follows ; 1. The wool fabrics woven with lower with lower count yarn are superior to those woven with higher count yarn in the property of compression and resiliance of compression. 2. All wool fabrics are superior to polyester/wool blended fabrics in the property of compression and inferior in the linearity. 3. In general as the cloth count of fabrics increases, the percentage of compression decrease and the linearity increases proportionally in wool fabrics.

This paper analyses current densities induced inside a worker using AC arc welder when he wears a protective cloth. Applying the boundary element method, we calculate current densities induced in organs inside a worker in case he was located at 1[cm], 15[cm], 20[cm] far from a power cable of AC arc welder. As results of study, we find a maximum current density induced in all organs may be lower than 10[$mA/cm^2$] if he wears a protective cloth. We also know high permeability materials can lower current density more than high conductivity materials.

This is a study of the history and the changes of methods of making shroud from Koryo up to present. Korea is Known as a country of East with its courtious people, and naturally the people observed the proprieties, especially on the funeral, in performing religious services and worshiping of the ancestors. Since Koryo and Yi Dynasty, because of the complexcity of the formalities under the confucianism, the shroud also became very complex. The process of making shroud was various according to the classes and economical circumstances. They made shroud of fine textured hemp cloth or silk, selecting one of 'good days' in leap year. As they believed the shroud should be rotten as soon as possible, fine textured hemp cloth was common as for the material. The color of the shroud was either plain or colored as the casual wears. In sewing shroud, the thread shouldn't be knotted nor connected in each seam and the strips should not be even numbered. These methods of making shroud have been changed variously and symplified according to the economical circumstances up to now.

Textile decalcomania printing is how after the disperse dye which is melting and vaporizing absorbs on the surface of the cloth, it colors by permeating into the cloth inside. So it has applied a lot to the synthetic fiber like polyester. However, because there is no showing right temperature and time in case of printing on the polyester fiber and the microfiber, this study aims at it. The experimental methods are like this : first measuring the density for the objective judgment, and measuring colors with the colorimeter, and then study for the color reproduction through a visual evaluation.

Chemical vapor deposition (CVD), ion beam sputtering (IBS) and sol-gel method were used to prepare TiO$_2$ thin films for degradation of hazardous organic compounds exemplified by 2-chlorophenol (2-CP). The influence of supporting materials and coating methods on the photocatalytic activity of the TiO$_2$ thin films were also studied. TiO$_2$ thin films were coated onto various supporting materials including steel cloth (SS), copper cloth, quartz glass tube (QGT), and silica gel (SG). Results indicate that SS (37 μm)- TiO$_2$ thin film prepared by IBS method improves the photodegradation of 2-CP. Among all supporting materials studied, SS(37 μm) is found to be the best support.

This study was carried out on the process of natural dye substances which can flock ultraviolet rays without producing harmful substances by pollution, germs, etc. While making human body safe in contact, extracting Gardenia, Sappan wood, Radix scutellariae, Cromwell, Mugwort, Gallnut, Lac. Those are used for curing diseases, dyeing silk cloth with those extracts, and examining the color fastness, Ultraviolet protection. From this study, the following conclusion was produced. Brightness was lower in pre-mordanting than in post. And color difference showed that Radix scutellariae was the highest. Aluminum-mordanting showed a higher color difference than Fe. Colorfastness to washing was high in all samples, and the degree of color-changing by washing was the highest in the sample dyed by gardenia, pre-mordanted gallnut showed the highest degree. Colorfastness to perspiration was the highest in gardenia. UV-A test showed that all samples a high rate of 85% or higher compared with test white cloth. Especially, post-mordanted radix scutellariae, pre-mordanted gallnut and post-mordanted sappanwood showed a superior blocking rate.

The purpose of the study is to analyze the dresses appeared in Nogultai. In the analysis of this study names and kinds of fabrics, colors, motifs, places of production and names of dresses were examined. In the study various kinds of fabric colors and motifs of fabrics were appeared in Nogulta. Also a variety of silks such s brocade, damask, plain silks, ra, silk gauze, hemp cloth, cotton cloth, wool and fur were found.

Mostly cleouds, flowers and mixtures of floral designs were used in silk brocades, Walrus was motif the only animal revealed in silk brocade. Nanching, Hanchaw, Suchaw were famous production centers of silk damasks, silk gauge and silk ra. Also Shantung and Suchaw produced good quality plain silk. Various kinds of coats, waded coat, wadded short coat, inner jackets, vest trousers, winter cap were included. Also accessories such as belt, cap, boots, socks, money belt, pouch were described. In addition, cosmetics, cosmetic kits and names of semi precious stones were mentioned. Seasonal garments differed according to kinds of fabrics and materials used. Wadded coat, wadded short coat, vest, winter cap and wool socks appeared as winter wear.

본 논문에서는 경계 합성곱 신경망(Convolutional neural network, CNN)기반의 슈퍼 해상도 기법을 이용하여 저해상도 옷감 메쉬를 슈퍼 해상도로 노이즈 없이 안정적으로 표현할 수 있는 기법을 제안한다. 저해상도와 고해상도 메쉬들 간의 쌍은 옷감 시뮬레이션을 통해 얻을 수 있으며, 이렇게 얻어진 데이터를 이용하여 고해상도-저해상도 데이터 쌍을 설정한다. 학습할 때 사용되는 데이터는 옷감 메쉬를 지오메트리 이미지로 변환하여 사용한다. 우리가 제안하는 경계 합성곱 신경망은 저해상도 이미지를 고해상도 이미지로 업스케일링 시키는 이미지 합성기를 학습시키기 위해 사용된다. 테스트 결과로 얻어진 고해상도 이미지가 고해상도 메쉬로 다시 변환되면, 저해상도 메쉬에 비해 주름이 잘 표현되며, 경계 부근에서 나타나는 노이즈 문제가 완화된다. 합성 결과에 대한 성능으로는 전통적인 물리 기반 시뮬레이션보다 약 10배 정도 빠른 성능을 보여준다.

In this paper, the physical properties of actual fabric data are predicted using the Cusick drape system, which is a means of measuring the physical properties of fabrics. Using a three-dimensional volumetric system, the cloth data of the actual Cusick drape system is acquired in a three-dimensional point cloud format. Cusick drape simulation is performed using mesh data of the same shape and size as the fabric, and the physical parameters of the draped fabric most similar to the actual draped fabric are acquired.
