This study is considered about the fabrics culture of Baekje Period by analyzing the fabrics pieces at a inner part of the It-bronze shoes found at the tomb of King Mu-ryeong in 1971 AD. The analysis methods of the fabrics pieces are a photographing of fabrics pieces surface by VMS, Digital camera(Nikon Coolpix 995) and the analysis of samples by SEM, XRD and FT-IR. It is assumed this fabrics pieces are the inner shoes, which consisted of compound woven silk at outward, some of tabby and a hemp at inward and the braids for decoration, of the gilt-bronze shoes. The features are as follows. 1. All of compound woven silk are the warp-faced compound tabby of plain fabrics and the density is various from high to low one. Compound woven silk which is attached the gilt-bronze shoes of the tomb of King Mu-ryeong weaves in high density by a thick thread. The fibers material of compound woven silk prove to be a silk by the analysis of wrap samples by SEM, XRD and FT-IR. 2. Tabby are excavated under the condition which attached on reverse side of compound woven silk. Those ran classify two types. First, the fine weaving by high density of wrap and weft. Second, the loose warp weaving with one warp and some of weft. 3. Hemp is almost ramie by SEM analysis and the density is different. Ramie which supposed to be attached Guem has the very low density. In addition to, Ramie pieces, excavated in condition and weaved finely, proved the conspicuous weaving skill in Baekje period. 4. Various kinds of braid are found and these ones classifies by fiber material and entwining way. Two types out of these are the one of silk thread, decorates the upper, middle parts of compound woven silk shoes and the other of hemp thread, decorates the lower parts.

The harsh nature of welding environments makes welding a prime candidate for process automation. Among the variety of welding processes available, gas metal arc welding is one of the most frequently used methods, primarily because it is highly suited to a wide range of applications, and also to automation. Automatic seam tracking method is one of the most demanded techniques for automatic control of arc welding. In this study a seam tracking system has been developed by using the welding arc itself as a sensor. This paper described the principle and experimental result of the arc sensor system, as well as the development and application of the automatic CO_2$ welding for the horizontal fillet welding. A basic problem in horizontal fillet welding is the prevention of hanging bead formation such as undercut at the vertical plate and overlap at the horizontal plate. To produce the symmetric bead shape, the relationship of bead shape to welding parameters(welding velocity, weaving width, weaving speed, tip to workpiece distance) was also investigated.

The purpose of this study was to research the design methods to express jacquard design using CAD. For this study, two design patterns were divided; in addition, each design pattern is applied to two different weaving types, single woven fabric and double well cloths. As a result, 16 samples were produced by applying 4 design methods (warp shrunk as half size design/weft shrunk as half size design - A, warp shrunk as half size design/weft original size design - B, warp original size design/weft shrunk as half size design - C, warp original size design/weft original size design - D) to the two design patterns with the two weaving types. The result of this study can be summarized as follows. 1. The most delicate design method was Method D. However, Method B which took half the time less than Method D was almost as delicate as the Method D on the surface. 2. Method B was judged as a considerably efficient method for time and cost. 3. Method D was considered as most suitable for elaborate parts and delicate lines. However, it was considered uneconomical since it took the longest time. 4. Mettled A took 2.5 times less time than Method D. Therefore, Method A was more applicable to producing high density design. 5. Method C is not considered as a useful method as it showed rough surface and took long time by applying high design zoom except intentional design.

The purpose of this study was to grasp the utilization of traditional Korean Patterns used for fashion cultural products. To achieve this purpose, this study examined the range of fashion cultural products through literature review, previous researches, and market surveys and analyzed the situation of fashion cultural products and the kinds, expression methods, expression techniques, and repeat styles of utilized patterns. The analysis results are as follows. First, in the use of traditional pattern, the most frequently-used fashion cultural products were small and inexpensive accessories, followed by fashion apparel, miscellaneous goods, and living cultural goods. Second, the most frequently-used traditional patterns were plant patterns, especially flower patterns. The next frequently-used ones were mixed patterns, especially in the mixture of flower and letter patterns, and $cloisonn\'{e}$ and flower patterns. The next frequently-used traditional patterns were animal patterns(especially butterfly patterns), followed by geometric patterns, lucky omen patterns, and letter patterns. In the expression methods of used patterns, most products except handicrafts preferred simplified patterns to real patterns. Finally, in the expression techniques of traditional patterns, the most frequently used technique was traditional embroidery, followed by the use of weaving fabrics such as fine gauze and brocade which are used for Hanbok. Also, transfer dyeing which is one of printing techniques, DTP(digital textiles printing), a mixed technique which adds embroidery to weaving fabrics, hand-painting, and a gilt technique were used. The results of this study suggest that most fashion cultural products except few designers' works attached weight to some specified patterns and expression techniques regardless of the characteristics of products since there is little understanding of a variety of patterns and are few researches and development on expression techniques.

In these days. the finite element method(FEM) is a very common method for not only a simple vibration analysis but also the optimization of structures. Since the finite element model may contain thousands of degree of freedom, the eigensolutions require extreme computing power, which will result in a serious time-consuming problem. Thus, many researchers have challenged to find more improved modeling techniques and calculating methods to overcome such problems. The Guyan reduction method and the substructure synthesis method are typical examples of such methods. Of the substructure synthesis method, the component mode synthesis method (CMS) is widely used for dynamic analysis of structure. In this study. for the efficient analysis of jet loom structure. Component Mode Synthesis was carried out. The results of the finite element program developed are compared with those of the commercial package program ANSYS for the validation of the program. The results obtained by the program showed a good agreement with those of ANSYS. The program will be further refined and verified by test to yield more accurate results.

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.
