As the development of denim products using new differentiated materials plays an important role regardless of their target age groups, there is an increasing need for the development of premium denim designs for senior women using various materials. As part of the strategy to develop such a design for the senior generation, a market survey was performed regarding commercially available premium denim products in the market, and the current trends in the denim market were researched and analyzed to make use of the results in design development. In addition, a differentiated material, hybrid yarn using conjugated dyeing (HYCD) was applied to use several washing techniques capable of highlighting the unique features of denim clothing. The design of four items including a jacket, vest, capri pants and long pants were suggested. These items were differentiated from other products by emphasizing their details such as stitching and pockets. In light of the current consumer trend to select denim jeans on the basis of their fashion-ability (e.g., silhouette or color) rather than practicality or price, it is considered meaningful to develop high value added, premium jean products for the senior generation using diverse materials and details. At the same time, performing further studies designed to demonstrate the stability and reliability of the developed products through consumers' comparative assessment is required.

Tyrosinase has two types of enzymatic activities, cresolase catalyzing the hydroxylation of monophenol and catecholase catalyzing the oxidation of o-phenol. Gradual inactivation of the enzyme during the reaction is a barrier to be overcome for the commercial application of the enzyme. Tyrosinase was stabilized by modifying the lysine residue of the enzyme using glutaraldehyde. In addition to that, tyrosinase was also stabilized by adapting the continuous reactor system. In packed bed reactor quinone could be easily removed, so the stability of tyrosinase increased. Borate buffer retarded the reaction rate of catechol to quinone and consequently decreased the tyroslnase inactivation. Tyrosinase immobilizer on controlled pore glass showed significantly enhanced stability in a packed-bed reactor.

The aberrant movement that Gilles Deleuze wanted to describe represents 'unclosed' or 'unlimited' possibility; it also means that a being has unlimited virtual power until it turns into a thing. In this paper, I analyzed and classified "Dialogue Factual,"one of the animation films by Jan Svankmajer, based on the logical grounds by Gilles Deleuze. First, as a result of analysis according to the seven characteristics in the experimental animation by Paul Wells, 'Dialogue Factual' has all of the features in the experimental animation, and, as I have found, the analysis through a comparison with Carl Dreyer's "The Passion of Joan Of Arc" indicates the works by Jan Svankmajer do not conform to Sensory-motor schemata. Such aberrant properties are involved with the time-image by Gilles Deleuze; by comparison with "Lavender Mist No. 1", one of the artworks by Jackson Pollock, it has been confirmed that "crystal image," the important concept of the time-image, is inherent in "Dialogue Factual". Lastly, the analysis of shots suggests that the movement-image and the time-image coexist in "Dialogue Factual". However, they are not to be classified by a clear-cut dichotomy.

In this study, shear thickening fluid (STF) filled with rigid nano silica particles was impregnated in plain woven Kevlar fabrics to improve the impact resistance performance. The nano silica particles with an average diameter of 100nm, 300nm, and 500nm were used to make shear thickening fluid to estimate the effect of particle size on the impact behavior of STF impregnated Kevlar fabrics. The yam pull-out and frictional tests were conducted to estimate the effect of impregnated STF on the frictional characteristics. The test results showed that the friction forces were dramatically increased at the STF onset shear strain rates that were measured in preliminary rheology tests. The low speed impact tests were performed using the drop test machine. The results showed that the impregnated STF improved the impact resistance performance of the Kevlar fabrics in terms of the impact energy absorption and the deformation. It has been shown through tests that the impregnated STF affects the interfacial friction which contributes to improve the energy absorption in the Kevlar fabrics. Especially, the impregnation of the STF with the smaller particle size into the Kevlar fabrics showed the better performance in impact energy absorption.

최근 링 정방기의 생산속도 증가로 인해 사절 및 사물성에 큰 영향을 미치는 정방장력의 중요성이 더욱 커지고 있다. 링 정방장력은 스핀들 회전수, 트래블러 중량, 링직경, 콥 직경 등과 같은 공정인자와 링 레일 상하운동에 따른 벌룬 높이, 얀 가이드에서의 실 굴절각도, 콥의 권취 반경 및 공기저항 등에 의해서도 영향을 받게 된다[1]. 이와 관련하여 링 정방장력 해석[2], 정방 공정인자가 정방장력에 미치는 영향[3] 및 정방 공정인자가 방적사 물성에 미치는 영향[4] 등의 연구가 많이 이루어져 왔다. (중략)
