This paper proposes a denoising method for the contour edges and crease edges of silhouette obtained from 3D scanned data of stone cultural heritages. It is often the case that the silhouette involves noise in the form of short-length line segments, due to rough surfaces of stone cultural heritages, weathering, and technical difficulties arising in data acquisition. Thus the removal of the short-length line segments from the contour edges and crease edges can result in a clear and accurate silhouette. An efficient computational algorithm is introduced to count the continuity of line segments; edges having not more than 3 line segments are removed. It has been verified that the new method is more effective than threshold-based silhouette extraction methods for stone heritages. Our method is applicable for various other data which are deteriorated by short-length line segments.

An enzymatic flour milling process for barley into three major fractions (barley flour, bran-crease-germ and water solubles) was studied. Carbohydrate and protein of barley endosperm could be efficiently solubilized by the digestion process of partially pearled barley with enzymes. Bran, crease and germ were removed from hydrolyzate by filtering through 30-40mesh sieves. And then filtered product was separated into fractions by sedimentation or centrifugation. The most effective digestion of the barley was obtained by the enzyme with higher activities of glucanase and protease under such conditions as barley-water ratio, 1:1.5(W/V) and temperature at $45^{\circ}C$. Total flour yield recovered was approximately 73-76% of the barley, and the portions recovered as bran-crease-germ and water solubles were about 3.6 and 15.8%, respectively.

This study was to investigated physical properties of lining fabric (Nylon, Acetate, Rayon and Polyester) such as shrinkage, tensile strength, moisture regain and crease resistance. The results were as follows. 1. The number of repeated washing times and the concentration of the detergent almost didn't affect on the change of tensile strength. 2. As washing increase more, the shrinkage of all sample was more increased. In the case of Rayon, it was showed that shrinkage was high by $1{\sim}3$ times washing. In the case of Nylon, it was showed minus shrinkage according to frequency of washing. 3. The moisture regain was very decreased by 1 times washing. But the moisture regain was increased with increase in frequency of washing and resulted in it was showed a similar value with controls. 4. As the frequency of washing and the concentration of detergent increase more, the crease resistance was decreased considerably because the elasticity of fiber decreased by mechanical force such as tension, bending and pressure and alkali.

The purpose of this study was to evaluate the physical properties and the hand of bast/man made fiber mixed fabrics compared to linen. The mixed fabrics were made by rayon, polyester and modal fiber as warp yarn, and ramie, flax, rayon/flax and cotton/flax as weft yarn. The crease resistance, drape, tensile strength/extension, water absorbancy and warmth retention were measured for test fabrics. The mechanical properties were measured by Kawabata system, and the hand value was calculated by previously developed equation. The results obtained from this study were as follows: The crease resistance and drape properties of bast/man made fiber mixed fabrics were improved compared to those of linen. The tensile strength of polyester/bast fiber mixed fabrics increased compared to those of linen, but rayon/bast and modal/bast fiber mired fabrics decreased. The extension of all mixed fabrics was increased compared to that of linen. The rayon/ramie and modal/ramie mixed fabrics showed lower warmth retention than linen. The mixed fabrics used rayon and modal as warp yarn showed higher water absorbancy than linen. The Koshi and Hari hand value of all mixed fabrics showed lower than those of linen. Fukurami hand value showed little difference between mixed fabrics and linen. Shari, Kishimi, and Shinayakasa hand value of rayon/bast and modal/bast fiber mixed fabrics showed higher than those of linen.

The purpose of this study was to investigate the effect of alkali treatment on EG solution of polyester/silk union cloth(P/S cloth) . Tensile strength, moisture regain, crease resistance, and reduction ratio of the treated P/S cloth were measured. The results of this study were as follows ： 1) The weight loss of P/S cloth treated with EG solution was three times higher than those of P/S cloth treated with $H_2O$. The weight loss of P/S cloth was increased greatly with increasing concentration of NaOH, temperature, and time. Favorable weight reduction of treating condition could be obtained when lower concentration of NaOH was used with longer time. 2) If it was added $H_2O$ on EG solution, weight loss of polyester increased, while those of silk decreased. In addition, decreasing ratio of tensile strength warp direction (polyester) was lower, while those of weft direction(silk) was higher. 3) Moisture regain of P/S cloth treated with EG solution increased with weight loss up to 10% . Crease resistance of P/S cloth was the highest at weight loss of 10~15%.

Purpose: The transaxillary approach for breast augmentation has been advocated for patients and surgeons for several decades. However, this blind technique had many disadvantages including, traumatic dissection, difficult hemostasis, displacement of implants, and ill-defined asymmetrical location of inframammary crease. In the present study, the precise endoscopic electrocautery dissection was applied to eliminate the limits of blunt dissection throughout the procedures. Methods: From December 2006 to December 2007, a total of 103 patients with an average age of 29.5 years underwent endoscopic assisted transaxillary dual plane augmentation mammoplasty. The mean implant size was 243 cc with the range between 150 and 350 cc. Through a 4 cm axillary incision, electrocautery dissection for submuscular pockets was carried out under the endoscopic control. The costal origin of pectoralis muscle was completely divided to expose subcutaneous tissue and to make type I dual plane. Results: Using the endoscopic dissection, we achieved good aesthetic results including a short recovery period, less morbidity, and symmetrical well-defined inframammary crease. Type I dual plane procedure could support the consistent inframammary fold shape and be applied to most patients without breast ptosis. Minor complications did not occur, however, four major complications of capsular contracture occurred. Conclusion: In contrast to the era of the blind techniques, endoscopic assisted transaxillary dual plane breast augmentation can now be performed effectively and reproducibly. With Its advantage, the axillary application of endoscopy for augmentation mammaplasty is useful to achieve the optimal cosmetic outcomes.

The effects of water-and oil-repellent finishes on the surface characteristics of polyester fabrics were investigated in this study. Three kinds of fluoropolyment were selected as water=and oil-repellent finishing agents. The effects of water-and oil-repellent finishes were determined by the water repellency and oil repellency. The surface properties of untreated and treated polyester fabrics were evaluated with respects to crease resistance, contact angle and wicking time. The results of this study were as follows: 1. The polyester fabrics treated with fluoropolymers showed much higher water repellency and oil repellency than those of untreated polyester fabrics. Water-and oil-repellency of fabrics were increased with the crystallinity and the hydrophobic-hydrophillic components of fluoropolymers. 2. Water repellency of fabrics treated with fluoropolymer with hydrophobic components was the highest. Oil repellency of fabrics treated with fluoropolymer with high crystallinity was the highest. Water-and oil-repellency of fabrics treated with fluoropolymer with hydrophyllic components was low comparatively. 3. The crease resistance of polyester fabrics treated with fluoropolymer nearly approached to that of untreated polyester fabric. 4. The water-and oil-repellent finishes improved contact angle markedly. Especially the contact angle of ployester fabric treated with fluropolymer with hydrophobic component was the biggest. 5. The wicking time of polyester fabric treated with fluropolymer with hydrophobic component was the longest.

When coated paperboard is printed, pressed into a groove with a creasing rule and folded, white line cracking occurs along the crease due to intensive mechanical pressure. The cracking will deteriorates product quality and waste resources. Effects of creasing pressure and ink dosage on the foldability of coated board were investigated. It was shown that applying an optimum pressure is important during creasing. When the pressure was too low, the crease formed was not sufficiently deep enough to enable precise folding. When an excess pressure was applied, fiber bonding was destroyed, resulted in unsatisfactory cracking. When the coated board was folded in machine direction (MD), long cracks were formed along MD. When it folded in cross direction (CD), the cracks were shorter and formed perpendicular to CD. Printing promoted cracking due to the decrease in flexibility of coated board. In addition, uneven ink film layer on the coating layer caused worse cracking.

The aim of the work described in this paper was to confirm the application of the equation of the soil-water characteristic curves on an unsaturated soil. A series of suction test for unsaturated soils was conducted on the selected 4 kinds of soil using modified pressure extractor apparatus. And it was carried out to analyse The experimental parameters which can be describe the soil-water characteristics, were determined by using the data obtained from the experiment. From the results, it was found that The matric suction varied according to the grain size distribution, amount of fine grain particles and void ratio. Also it was found that the residual degree of saturation was decreased with in crease of the void ratio, but the pore size distribution index and air entry value were increased with in crease of the void ratio. And The application of the soil-water characteristic curve equation was confirmed for the various conditions and the various state by the comparison between the measured degree of saturation and the predicted degree of saturation.
