인간의 건강한 생활을 위해서는 자세 및 골격구조가 중요하며, 이것은 평소의 생활습관과 걸음걸이에 의해서 영향을 받아 변형될 수 있다. 인간의 걸음걸이형태로는 크게 바른걸음, 팔자걸음, 안짱걸음으로 구분할 수 있으며, 이러한 걸음걸이형태를 분석하여 바른자세를 유지하는데 도움이 될 수 있다. 본 논문에서는 스트레인 센서를 이용하여 걸음걸이 패턴을 분석하는 신발을 개발하였으며, 제작된 신발로 걸음걸이 패턴을 구분하여 분석할 수 있었다.

Two-Phase flow pattern and pressure drop data were obtained for pure refrigerants R134a and R123 and their mixtures as test fluids in a horizontal tube. The flow pattern is observed through tubular sight glasses located at inlet and outlet of the test section. The flow map of Baker developed for air-water two-phase flow at atmospheric pressure failed to predict the observed flow patterns at the higher value of the mass velocity used in the present study. The map of Kattan et al. predicted the data well over the entire region of mass velocity selected in the present study. The measured pressure drop increased with an increase in vapor quality and mass velocity. A new two-phase multiplier was developed from a dimensional analysis of the frictional pressure drop data measured in the present experiment. This new multiplier was found successfully to correlate the frictional pressure drop.

Large area micro pattern replication has promising application potential in many areas. Rolling imprint process has been demonstrated as one of the most competitive processes for such micro pattern replication, because it has advantages in low cost, high throughput and high efficiency. In this paper, we developed a prototype of roll-to-flat(R2F) thermal imprint system for large area micro pattern replication process, which is one of the key processes in the fabrication of flexible displays. Experimental tests were conducted to evaluate the feasibility of system and the parameters' effect on the process, such as flat mold temperature, loading pressure and rolling speed. 100mm $\times$ 100mm stainless steel flat mold and commercially available polycarbonate sheets were used for the tests. The experimental results showed that the developed R2F system is suitable for fabrication of various micro devices with micro pattern over large area.

Traditional culture could be a wonderful source of inspiration for creative design. Tteoksal, the stamps used for making decorative patterns on traditional rice-cakes, have been used and passed on to generations to show the emotions of our ancestors. Numerous traditional patterns found in Tteoksal can be used to better understand and transmit tradition in modern ways. The purpose of this study was to develop fashion cultural products with a modern sensibility by understanding the origin, types and characteristics of Tteoksal and its patterns. The method of this study was through considering the proceeding studies and the references published by a specialist and museums having some information about further knowledge on Tteoksal. In line with the aforementioned study, neckties, eco-friendly bags and pouches were developed as fashion goods. Among the Tteoksal's patterns selected were lotus, bats, 樂 letters and complex patterns. Using a computer graphic software program such as Adobe Illustrator CS5, archetypes of patterns were traced as vector graphics, and two design motives were developed in every pattern. The patterns were developed into two types: one was a basic pattern faithful to a basic motive pattern, and the other was a varied type that was changed and applied. The fashion products were developed as two styles for basic and varied patterns for neckties, eco-friendly bags and pouch items. Twelve products were made for each pattern, which totals 48 unique products. In conclusion, the study could be a critical step to better understand the traditional culture and its influence to the patterns applied to modern fashion design.

This study used 3D technology to develop a multi-functional sports brassiere with increased comfort and fit that can be worn as a base layer during exercise or as underwear. A 75A size industrial lingerie figure was used to develop a standard pattern. 3D tools for scanning and pattern making, such as Vivid 910, Geomagic Design X, 2C-AN and Yuka CAD were used. The sports brassiere was designed as a tank top style with dual structure and linings attached to a pad utilized with a sport brassiere mold cup. 3D outer and lining's pattern was differently developed in consideration of the body's curvature with pad's shape and structure. Shoulder and neck part reduction rates were adjusted to increase the neck areas fit that considered the nude pattern's structure due to uncomfortableness felt by wearers who were uncomfortable with the neck areas fit on existing brand products. The reduction rate was also set differently on each part. For example, the reduction rate on outer side panel was set strongly to increase the breast's volume. Two products, developed by a 3D sports brassiere and previously released product, were worn on 8 subjects in their 20's to evaluate fit, comfort, and purchase preferences. The evaluation proved that newly developed 3D products were superior to comparative products. The results of the clothing pressure measurement indicate that the newly developed sports brassiere's front part had less pressure on upper bust and shoulder areas compared to comparative products as well as showed less pressure on the back side, which shows improved wearing comfort compared to comparative products.

The purpose of this study was to develop a computer program for pattern making of women's Dooroomaky. The following results were given through utilizing the Computer in pattern making of Dooroomaky for women. 1. Computerization of the pattern making process was expected to provide higher accuracy and efficiency in pattern making. 2. Basic pattern was drafted by the hand-operation. In this study, this Dooroomaky basic pattern was selected. And a computer program for drafting was developed. Refer to
