To study the visual evaluation on the effect of ruffle's gather, the aesthetic evaluation on the gather's measurements and the image evaluation were performed. Evaluated fabrics were cotton, wool ani synthetic fiber, and 3 kinds of thickness for each fabric were selected. In order to seek for aesthetic gather's measurements, we performed the sensory test by the Rank Method on 5 kinds of gather's measurements(I.5 times, 1. 8times, 2times, 2.5 times, 3 times). For the image evaluation on the effect of the gather, we performed the sensory test by the Semantic Differential Method on the gather's measurements were got high score in the sensory test of the gather's measurements and analyzed by means of a Factor Analysis. The results were as follows. 1. Except 2 times of fabric $A_1$(thin cotton), the aesthetic gather's measurements of the ruffle were evaluted 2.5 times in cotton and synthetic fiber, and 2 times in wool. Generally the aesthetic gather's measurements of the ruffle were 2$\~$2.5 times. 2. The image characteristics of the ruffle were established the characteristics of the fabrics as factor 1, the characteristics of the atomosphere as factor 2 and the characteristics of the drape as factor 3. Therefore, we must consider the characteristics of the fabric, the atomosphere and the drape of the ruffle in production of the ruffle.

Environmentally and human compatible chitosan were pretreated on cotton fabrics which were then dyed with 100% persimmon juice. The chitosan concentration was 1% and the chitosan types were high molecular weight chitosan (1980cps), low molecular weight chitosan (18첸), chitosan oligomer and water soluble chitosan. The properties of the fabric surfaces, the dyeabilities, the color fastnesses, the antibacterial activities, the strengths, the elongations and the drape stiffnesses were evaluated. The properties of the chitosanpretreated, persimmon juice-dyed cotton fabrics (CLP) were compared to those of the untreated (CN), chitosan treated (CL) and persimmon juice-dyed fabrics (CP). The results were as follows. The fibers extruded from the surface of CN decreased on CP. The air between the fibers within CN were substituted by chitosan solution or persimmon juiceand decreased within CLP according to SEM observations. The effects of chitosan treatment, the chitosan molecular weights and the degrees of deacetylation of chitosan on the dyeabilities of the persimmon juice-dyed cotton fabric were not distinct. The curing after chitosan padding improved the dyeabilities of CLP compare to noncuring. The strengths of CP decreased and those of CL increased, compared to those of CN. The strengths of CLP were greater than those of CP. The elogations of CP and CL were greater than those of CN. The strengths and elongations of CLP were greater than those of CN. The chitosan treatments improved the strengths but not the elongations. The drape stiffnesses of CL, CP and CLP were greater than those of CN. The antibacterial activites of chitosan pretreated, persimmon juice-dyed cotton fabrics against Staphylococcus aureus were increased by more than 98% by persimmon juice.

Weighting of silk fabrics have long been practiced in silk fabric trading based on the primary consideration of price-weight, and secondary one of quality improvement in handle, luster, and drape properties. Recent trend of practicing weighting of silk fabrics is, however, focused on the improvement of the handle, luster, drape, and other properties. During the finishing processes of synthetic fiber, nylon, comprising amide structure, include the use of tannic acid, especially in the dyeing. A multitude of studies are being implemented in terms of improving fastness to washing, fastness to light of dyed nylon product, or the light fastness of nylon 6 itself. In this study, the effects of various tannic acid treatments on the physical properties related to the handle of nylon 6 and silk fabrics are examined and reviewed. The effects of treatment condition of the tannic acid, e.g., the concentration of the aqueous tannic acid solution, treatment time, and temperature were investigated. As the concentration of the aqueous solution of tannic acid increased, the bending rigidity values of the silk and nylon 6 fabrics increased. The treated fabrics felt stiff to the touch. Within the mild conditions of bending employed in the bending measurement of KES, nylon 6 treated fabric specimen exhibited a trend of improvement of bending resiliency within the range of small bending deformation. The weight of treated fabrics have all increased. The air-permeability values decreased as the treatment concentration increased. However, the decrease tendency of air permeability values may be alleviated by adjusting the fabric count during the tentering or expanding processes, either by tension adjustment or heat treatment. Optimum conditions of the treatment for nylon 6 are 1.25% tannic acid concentration, bath temperature of $85^{\circ}C$, pH 3.1, and those for silk fabric treatment are 1.25% tannic acid concentration, bath temperature of $85^{\circ}C$, pH 3.1. The treatment conditions will lead to the improvement in the properties of fabrics for summer.

노즐시험기로 측정되는 직물의 당김 힘은 직물이 갖는 포괄적인 촉감을 나타낸다. 노즐시험기는 기존 KES 시스템보다 저가이며, 측정에 있어서 절차가 간단하고 빠르다. 본 연구에서는 노즐시험기로 측정되는 직물의 촉감을 정량적으로 평가하기 위해 마찰법칙을 기초로 하여 반 실험적 촉감 방정식을 개발하였다. 모델 식에서 고려된 변수들은 직물의 마찰계수, 그리고 직물의 굽힘 길이와 전단 신도에 의해 결정되는 직물의 3차원적 변형 특성을 나타내는 드레이프 계수이다. 12 종류의 서로 다른 물성의 면과 폴리에스터 직물들을 사용하여 실험 측정한 촉감 값과 모델 방정식으로부터 예측한 촉감 값들을 비교 분석하였다. 높은 마찰계수, 높은 굽힘 길이, 그리고 낮은 전단 신도를 갖는 직물일수록 높은 촉감 마찰력, 즉 낮은 촉감 성능을 보여주었다. 실험 측정한 촉감 값과 모델 식으로부터 계산한 값들 사이 잘 일치하였으며, 이와 같은 결과는 모델 식을 사용하여 직물의 고유 물성들로써 촉감의 객관적인 예측이 가능함과 더불어 촉감 성능의 향상을 위한 직물설계에 있어서도 유용한 정보를 제공할 수 있음을 보여준다.

Background: This study purposed to examine how the incidence of the central line-associated bloodstream infection (CLABSI) in a operating room (OR) is affected by bundle application on central line insertion (CLI) practice. Methods: The study design was a pretest-posttest experimental trial. The subjects were 83 patients before the bundle application on CLI and 70 patients after. Results: The compliance(%) of bundle on CLI of among those who observed all of the five items increased from 7.2% before the intervention to 72.9% after. By items, compliance with the maximal barrier precaution was 100% for the use of a mask and cap before and after the intervention, but increased from 73.5% before the intervention to 88.6% after for the hand hygiene, from 73.5% to 88.6% for the use of a sterile gown, and from 9.6% to 75.7% for the use of a sterile large drape covering the whole body. CLABSI did not happen on CLI either before or after the application of the bundle intervention. Conclusion: Bundle application increased compliance with the use of a sterile gown and the use of a sterile large drape. However, its effect in the prevention of CLABSI was not clear probably due to the short period of intervention in a single hospital.

Lyocell is a regenerated cellulosic fiber manufactured by an environmentally friendly process. The major advantages of lyocell are the excellent drape forming property, the genuine bulkiness, smooth surface, and high dry/wet tenacities. However, one drawback of lyocell is its fibrillation property, which would degrade its aesthetic quality and lower the consumer satisfaction. In our previous studies, lyocell was treated with epichlorohydrin, a non-formalin based crosslinker, to reduce its fibrillation tendency. To investigate the changes of physical properties upon ECH-treatment, the hand characteristics of ECH-treated fabric were observed using KES-FB system and the 3D-virtual sewing image of the fabrics were obtained using 3D CAD simulation system in this study. Since epichlorohydrin(ECH) treatment was conducted in the alkaline medium, the weight reduction was observed in all treated lyocell. The treated lyocell became light, smooth and flexible in spite of ECH crosslinker application. LT and RT in tensile property upon the ECH treatment did not change significantly, however, EMT and WT in the tensile property increased. The significant decrease in bending rigidity was resulted in all ECH-treated lyocell, which is the result of the weight loss upon the alkali condition of ECH treatment. The bending rigidity increased again in the ECH 30% treated lyocell, however, the B value is still lower than the original. Therefore, the ECH-treated lyocell would be more stretchable and softer than the original. Shear rigidity was also decreased in all ECH-treated lyocell, which would result in more drape and body fitting when it is made as a garment. The ECH-treated fabric showed the softer smoother surface according to SMD value from KES evaluation. The virtual 3D sewing image of the ECH-treated lyocell did not show a significant change from that of the original except ECH 30% treated lyocell. ECH 30% treated lyocell showed a stiffer and more puckered image than the original.
