The purpose of this study was to find out the traditional decoration techniques in the Korean costume. Both quantitative and qualitative research methods were used to collect and investigated the traditional decoration techniques used in the related literatures and museum catalogues. The results were as follows. The broad and back stitching are fundamental stitching, which used to Nubi and Keki. Top stitching applied broadly to the Korean costume, for example, Jergori, Wonsam, Jeonbok, Beosun, Bojagj and so on. The expression techniques for top stitching were one, two or three stitches. When the top stitching was used as colorful stitches, they were more decorative. The Zatmulim was used for the decorative effect on the seam line because it was triangular shaped and became more effective by changing the rotor and size. Sunmulim was used on the narrow line such as the seam lines of Gergori and Chima. The bakchi decoration was imitating a bat shape, had a meaning of bringing the goodness and gave the tiny and elaborated image. It was used to the neckline of Geogori, seam line of Chima, Pungcha Bazi and so on. Sattgi was used to attaching the bottom of two stiff fabrics adopting for Beosun, Ayam and Norigae. When it used colorful strings, the more decorative effect was added. The knot for button used the fabric instead of buttons and applied to the Cheonlik, Gergori. The aesthetic values of the traditional decoration techniques in the costume were both natural beauty and practicality with creativity.

This paper is about the development of automatic FPC(flexible printed circuit) punching instrument for the improvement of working condition and cost saving. FPC is used to detect the contact position of keyboard and button like a cellular phone. Depending on the quality of the printed ink and position of reference punching point to the FPC, the resistance and current are varied to the malfunctioning values. The size of reference punching point is 2mm and the above. Because the punching operation Is done manually, the accuracy of the punching degree is varied with operator's condition. To improve this manual punch ing operation to the FPC, automatic FPC punching system is introduced. Test algorithms and programs showed good results to the designed automatic punching system and led to the increasement of productivity and huge cost down to law material like FPC by avoiding bad quality.

This study aims to provide the basic reference necessary in improving the fitness of a ready-to-wear brand jacket through a research on the wearing conditions and preferences regarding a tailored jacket by body shape of the women in their 30s. The following results were drawn by implementing the research method of the self-administered type survey targeting 201 women in their 30s from August 14~28, 2014. First, the female consumers in their 30s preferred one button slim fit jacket when purchasing a tailored jacket and chose a close-fitting size. Second, the slim fit tailored jacket consumers preferred a jacket with some extra portion in the bust and hip areas but tightly fit in the waist area. Third, when purchasing a jacket under the ready-to-wear size system, the women with a triangle shape similar to a standard body silhouette had less instances of mending a jacket while the women with a big or small rectangle shape different from a standard body silhouette had more experiences of mending a jacket. Accordingly, it is expected of the manufacturers to increase the fitness satisfaction of the consumers by identifying the problems concerning the fitness and suggesting the improvement plans to produce a jacket of a good fitness reflecting the properties of different body shapes through such research on the wearing conditions and preferences regarding a tailored jacket by body shape of the women in their 30s.

PDA(Personal Digital Assistants) and laptop computer that are small sized mobile implements are typical devices which capable of using wireless internet. They seem to have a tendency to possess multi-function as well as to miniaturize in accordance with taking advantage of today's digital convergence circumstance. It should be considered that the pointing input device of these mobile computer that have PDA size and laptop's performance has to be added to something very small instead of 4-button, 5-button navigator and with the electric pen. The basic framework for this study is to investigate the usability of the two input devices Trackpoint and Touchpad which regarded as a alternative pointing device for small sized mobile computer. 14 novice subjects compared a Trackpoint to a Touchpad across five curser-control tasks. The study found that subjects executed not more slowly with a Trackpoint input device than with the Touchpad. Observation shows that learning for Trackpoint appears to have had more than for the Touchpad. Subjects expressed preference for the Trackpoint in general work.

A study on the upper garment of Korean women, JUORI The upper garment of Korean women. JUGORI, is an inherited mode from the ancient clothing style in the various aspects based on the particulars of Korean clothes. The ancient style of clothes is originated from KWAMDUI belonging to inhabitants of Northern Territory of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korean penynsula. The changes of the pattern of JUGORI, in a word, is a sign of shortening tendency of size. This tendency of JUGORI is remarkably seen in the shortening of length and other parts are decreased in size. The JUGORI in the ancient age was fallen below the weist of woman, which is similar to Robe, and was worn with band. However, the length of the JUGORI has been gradually shortened, and therefore, GORUM took place of the band. The shortening tendency of JUGORI is seemed to be shown its sign in the initial time of its origin, because there are some evidences that the women in Sylla Dynasty, and this tendency has been much expedited during the period of Koryu Dynasty with influences of Monggorian culture (Won Lynasty of China) The oldest sample for data of JUGORI in nowaday is one the remains of Yi Dynasty, and this sample for data provides all the particulars of the modern pattern of JUGORI. The tendency of JUGORI had been continued even in Yi Dynasty, and at the end of the Dynasty, the clothes was shortened that the women felt inconvenient wearing it in the status of the shortened JUGORI which was even hardly cover the initial time of epoch of modernization induced from the Western civilization, and after 1920s and 1930s JUGORI become a larger tendency. This is a sing of revival of practical use and rationalization of JUGORI become a shortening tendency again, and the size is similar with that of early age of Yi Dynasty. Instead of these similarities, the particulars of modern JUGORI is weighing on much emphasis on curve beauty and expression of experior beauty. The reason is that, together with westernization of clothes, JUGORI became a special pattern of clothes as a traditional Korean women wears. The very thing explaining this pattern of JUGORI is the "ARIRANG DRESS". And there are some fashion using button instead of GORUM and half sleeve JUGORI for summer use which is regarded as a part of improved aspect of life in Korea. in Korea.

As interest grows in nursing-wear in accordance with dissemination of breast-feeding, a study on opening of nursing-wear is needed to enhance convenience of breast-feeding regardless of location. In this study, the items on nursing-wear were classified and each characteristic was analyzed. The types and characteristics of opening on nursing-wear were identified and the characteristics of nursing brassier closely related to the nursing-wear were also identified. Top 5 companies for the nursing-wear and nursing-brassier were selected by ranking top 5 in NAVER with the search word 'nursing-wear' and 'nursing-brassier'. 732 one-piece and top (t-shirt and blouse) which have the highest portion in the nursing-wear were selected as the subject. Based on the photo, product explanation on the internet and in-depth interview of designer, the types and characteristics of openings for each item were identified. 732 nursing-brassier were selected to study the types and openings in breast-feeding. The result is as follows. Firstly, the item of nursing-wear can be classified into top, one-piece, package of top and the bottom, and sleeveless. Top and one-piece have the highest production rate. Secondly, the types of the openings are either covering or opening types. There are vertical-slit and horizontal-slit in covering type, and vertical-zipper, horizontal-zipper, and button types in opening type, and overlap and pocket type for the rest. Thirdly, the commercially available nursing-brassier according to the opening manner can be classified into upper-opening, middle-opening, and overlap types. Most largely produced product is upper-opening type as it minimizes the exposure of the breast in breast-feeding. When producing the nursing-brassier, the measurement of the lower breast and cup size are considered.

This paper presents a comparative study of the AC and MFDC resistance spot welding process with consideration of sheet thickness. The previous studies have confirmed that there is difference in the optimum welding current and expulsion current with AC and MFDC. The aim of this study was revealing the effect of sheet thickness on weldable current range and expulsion behavior for AC and MFDC welding processes. The optimum welding current of AC was lower (1.6 kA) than MFDC welding process in 0.8 mm sheet thickness. Early nugget growth being caused by the peak current of AC developed weld interface deformation, which resulted in suppressing the growth of corona bond and occurrence of low current expulsion. The resistance spot welding for thicker sheet (1.4 mm) required lower current of 0.6 kA for the expulsion on the MFDC welding process. The growth of contact diameter (size of corona bond) and button diameter was linear up to the expulsion current with MFDC welding process. Therefore, more attention is required when the AC and MFDC resistance spot welding process is applied for different thickness of steel sheet combination for automotive application.

Hanboks have evolved throughout time; for example, the curved Barae has changed into a more modern and sophisticated straight one. The development of staining techniques has increased color selections with more luxurious designs. I suggested a design of Dolbok that considers functionality, practicality and economic feasibility through a comparison of past and present designs. I suggested a fusion Hanbok based on a traditional Dolbok for baby boys and girls. An abundance of cheap resources has decreased the tradition of hand down clothes; therefore, I created functional and economic methods to adjust a Hanbok for kids to wear a long time. First, I made it possible to adjust the length of a skirt by a slip stitch (or catch) stitch with a Seurandan (ornate lower band) and placed the button on shoulder part of the skirt for baby girls. The width of skirt is designed for a 4 year old instead of 1 year old to adjust the size and compensate for growing kids; however, the clothes still look stylish despite the overlapped area. Second, I made a baby boy's vest with a belt that follows traditional methods that were comfortable for width variation. Third, I made Geodeulji (sleeve-ends trimmed with wide bias) that enabled long or short sleeves. Geodeulji made with a variety of fabric colors will enhance the decorative effect. Fourth, I made the width of clothes adjustable by putting Korum (tie) ON Jeogori for baby boys and girls. There are many studies on Hanboks but few reports on modern Dolbok. I believe that designers should further study fusion Hanboks within framework of traditional Hanbok designs to increase comfort and appeal.
