Motivated by people highlighting important phrases while reading or taking notes we propose a neural network training method by highlighting defective pixel areas to classify effectively defect types of images with complex background textures. To verify our proposed method we apply it to the problem of classifying the defect types of tire band fabric images that are too difficult to classify. In addition we propose a backlight highlighting technique which is tailored to the tire band fabric images. Backlight highlighting images can be generated by using both the GradCAM and simple image processing. In our experiment we demonstrated that the proposed highlighting method outperforms the traditional method in the view points of both classification accuracy and training speed. It achieved up to 13.4% accuracy improvement compared to the conventional method. We also showed that the backlight highlighting technique tailored for highlighting tire band fabric images is superior to a contour highlighting technique in terms of accuracy.

This study explicates some properties of the fabrics used in the 16th century by examining and analyzing the 90 pieces of fabric excavated from the graves of Mr. Ryu of Jinju and his wife Mrs. Park of Euiin. The fabrics were classified into silk tabby(紬), thin silk tabby, satin damask(段), complex gauze(羅), mixture fabric with silk and cotton(絲棉交織), cotton(棉布) etc. Compared to other contemporary fabrics excavated previously, the fabrics unearthed from the couple's graves presented very naive feelings. Patterned satin damask occupied a small portion. In the case of plain fabric, little filament silk tabby(絹) or thin filament silk tabby(細紬) was unearthed. Important data on the history of Korean costumes are provided by the noteworthy, first-ever excavation of a small cap made of complex gauze(羅) and the tiger-leopard embroidered patches called hyoongbae(胸背), which were worn on the front and back of official robes made of tabby with supplementary gold thread(金線). Only 3 pattern types could be clearly identified in form, cloud pattern, lotus and vine pattern(蓮花蔓草), and small flower and treasures pattern(七寶細花). These three patterns are very similar to those of other 16th century fabrics unearthed previously in terms of the form and arrangement of patterns.

This study examined textiles used for ancient costumes of the $16{\cdot}17th$ century in Joseon period, focusing on fabric types and patterns of the costumes from tombs. The purpose of this study was focused on investigating the relationship between fabrics and social backgrounds, especially change in using fabrics through the war from Hidyoshi's Invasion of Korea in 1592. Since the war must have had an effect on the life of people's. The result of the study is that silk occupies $69{\%}$ of all textiles, and cotton, linen follow The weaving method of silk was primarily Plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo Period, were considerably decreased in Joseon Period. Types excavated fabrics in the $16{\cdot}17th$ century Joseon period can be said various. Of this, silk was the most remarkable one till Hidyoshi's Invasion of Korea in 1592, when the ratio of patterned silk dramatically decreased. Contrarily, the ratio of cotton and plain fabric increased rapidly in Hidyoshi's Invasion of Korea in 1592. It is supposed that the result is largely due to unusual condition of the war time. After the war, it is estimated that use of pattened fabric as well as silk was decreased. Patterns of textile fabrics in $16{\cdot}17th$ century were various. In result of surveying a trend of increment and decrement, it is known that the ratio of patterned textile fabrics decreased dramatically in Hidyoshi's Invasion of Korea in 1592 and Manchu war of 1636. Tendency of textile use by social Position is more notable. It is appeared that a lot of silk fabrics were used in High hierarchy. The excavated remain and ratio of silk were the highest in Kyonggi Province including Seoul.

The purpose of this study was to investigate the effect of contact type textile electrode structure on heart activity signal acquisition for smart healthcare. In this study, we devised six contact type textile electrodes whose electrode size and configuration were manipulated for measuring heart activity signals using computerized embroidery. We detected heart activity signals using a modified lead II and by attaching each textile electrode to the chest band in four healthy male subjects in a standing static posture. We measured the signals four times repeatedly for all types of electrodes. The heart activity signals were sampled at 1 kHz using a BIOPAC ECG100, and the detected original signals were filtered through a band-pass filter. To compare the performance of heart activity signal acquisition among the different structures of the textile electrodes, we conducted a qualitative analysis using signal waveform and size as parameters. In addition, we performed a quantitative analysis by calculating signal power ratio (SPR) of the heart activity signals obtained through each electrode. We analyzed differences in the performance of heart activity signal acquisition of the six electrodes by performing difference and post-hoc tests using nonparametric statistic methods on the calculated SPR. The results showed a significant difference both in terms of qualitative and quantitative aspects of heart activity signals among the tested contact type textile electrodes. Regarding the configurations of the contact type textile electrodes, the three-dimensionally inflated electrode (3DIE) was found to obtain better quality signals than the flat electrode. However, regarding the electrode size, no significant difference was found in performance of heart signal acquisition for the three electrode sizes. These results suggest that the configuration method (flat/3DIE), which is one of the two requirements of a contact type textile electrode structure for heart activity signal acquisition, has a critical effect on the performance of heart activity signal acquisition for wearable healthcare. Based on the results of this study, we plan to develop a smart clothing technology that can monitor high-quality heart activity without time and space constraints by implementing a clothing platform integrated with the textile electrode and developing a performance improvement plan.

The purpose of this study is to investigate characteristics of arrangement methods and weaving types of fabrics during 16-17 century. Research was done through the references of exhumed clothing in Chosun Dynesty. Seeing the waving types of fabrics of flower patterned fabrics of total 108 items, satin damask(Dahn) was 71items, took the majority. And the next order was twill(Neung) and plain(Ju). It means Dahn was the most popular fabric among the upper classes. It was regarded as one of the noble textiles, because of its luxurious appearance and pleasant touch. Flower patterned plain fabric(Munju) was found only 9items, even though the plain fabric was the most common used type. Assumed for the reason, Chosun government had restrict to extravagance of the people. In terms of the arrangement of flower pattern, it can be classified into three methods. The most common arrangement method was Arabesque type, followed by open order shaped type and scattering shaped type. In the repetition of pattern, there were brick-shaped pattern and half drop pattern which were spread flower pattern all over the surface of fabric.

The purpose of this study is to figure out the types and characteristics of the twill damask fabrics through literatures review of both domestic and Chinese documents and records. In addition, the study aims to review the characteristics of the twill damask fabrics found at Sukga Pagoda. The twill damask fabrics can be categorized in terms of the weaving method into Float Pattern on a Tabby Ground, Twill Pattern on a Tabby Ground, Float Pattern on a Twill Ground, Twill Pattern on a Twill Ground, and Without Pattern on a Twill Ground. The fabrics ran also be divided in terms of their name into Ki, Neung, and Munju. Four items of twill damask fabrics were found inside the Sukga Pagoda. All of them are Twill Pattern on a Twill Ground. At the primitive level of weaving skill, twill damask fabric was made by adding patterns with twill damask or BuJik on the background of plain weave. At more advanced level, the fabrics are weaved by making patterns with twill damask or BuJik on the background of twill damask. Compared to the relics of Koryo and Chosun Dynasty, these twill damask fabrics were loosely weaved with relatively thick thread.

This study suggests the sensing method of the Three-dimensional respiration rate sensor based on surface area changes, and exploring the design direction of the three-dimensional breathing sensor and the design orientation of the garment. To achieve this, two types of three-dimensional respiration rate sensor were produced, and the study of the dummy and the subjects studied. The study I investigated the possibility of measurement of the three-dimensional respiration sensor by the study variables of the sensor type and speed of respiration. The study II proposes a suitable type of sensor for each of the three measuring positions in addition to the study variables in the study I. To evaluate accuracy, reproducibility, and reliability of the three-dimensional respiration rate sensor, the BIOPAC was used to measure the respiration rate simultaneously with the three-dimensional respiration rate sensor. Through all these results of the experiment, it explored the possibility of measurement of the three-dimensional respiration sensor for the dummy. It also proposed a suitable type of sensor by measuring the respiration rate for the human body.
