  • Mohair is widely used as an airtight material for filling the gap between a window frame and sash. The purpose of this study is to investigate infiltration rate and opening force of sliding windows according to the mohair installation conditions. Infiltration experimental apparatus was set up, and the experimental results were applied to windows to find a correlation between infiltration rates and opening forces. When 4 rows of mohair were installed, the infiltration rate increase became 27.1% per clearance length increase of 1 mm, and the infiltration rate decrease became 5.7% per shortened length increase of 0.1 mm. For 4 rows of mohair, the opening force decreased by 28.2% as the clearance increased by 1 mm, and it increased by 9.3% as the shortened length increased by 0.1 mm.

  • The purpose of this study is to investigate the transition of luster material after the tweentieth century. This study was conducted by means of designer collection, journal of fashion, museum data, fabric exhibition and Internet data. The results of this study were as follows: Before the synthetic fiber period, the luster materials were used satin, chamuse, gauze, damask brocade and velvet, except cashmere, mohair and rayon. They are made from silk by the way of giving difference surface property. But since 1960s, it has used not only synthetic fiber with smooth surface but also vinyl, latex, natural leather, synthetic leather and metal. Luster material recently has a tendency to natural and soft shiny, example silket finish, chintz finish, silico coating finish with paper touch feel and so forth.

  • The recent fashion trend of knit wear is now changing to the various fibrous color combination which emphasizes the plain texture. It supports the human body curvature which is influenced by the slim style of woven wear. In this research work, the general characteristics and knit wear fashion trend are studied. The metallic fiber and fancy yarn are used widely as fiber materials for knit in nowadays. However, the light and functional materials are preferred. The general characteristics of knit which gives the feeling of light and warm are still prevailing using pure wool, kid mohair, and mixed wool with polyester. In order to provide the soft touch feeling, smoothness of fine fiber, and feeling of sponge, several kinds of finishing techniques such as bulky, felting, bonding, and quilting process are usually adopted. The knit wear fashion trend is mainly consisted of the basic design items, and it gives the feeling of luxurious and elegance. The more youthful feeling is adapted for the general style of knit wear of the certain target age. The woven wear trend such as season color, line and pattern are applied in knit wear trend in recent days.

  • The purpose of this study is to analyze and document special design elements of the knit material, such as yarn, stitch, and gauge used in various types of knit in a collection of men's fashion, and to provide basic data for database design. The analysis covers 37 brand collections of men's clothing, used to collect a total of 1,954 men's knitwear photographs, and others were collected from 12 collections from F/W to 2017 S/S collection through www.vogue.com. The results of the analysis of the knit design elements of the contemporary men's collection since 2011 are as follows. First, there were 1,513 straight yarn (77%) and 440 decorative yarn (23%) types of yarn. There were many different kinds of decorative yarn, such as two tone and melange effect in three colors, and the emergence of hairy yarn, like mohair and angora shannell, which was much common in low gauge's knitwear designs. Second, the frequency was high with low and middle gauges. thin and light high-gauges were often found in S/S collections, but there were also thick types of yarn in low-gauge knitwear. Third, 794 (40.6%) items used basic stitches such as plain stitch, which was the most utilized. The plain stitch, which is the most basic of the knit stitches, appears to be in high demand for its use, along with the use of various decorators. The development of printing and dyeing technologies has led to many designs that utilize the printer for the plain stitch. 326 (16.7 %), of colored jacard stitch, and of 175 (0.9 %) of intasia stitch.

  • The knit design of this study was developed from reconstruction of Gustav Klimt images including gorgeous colors, symbolic lines, patterns and decorations, and the purpose was laid at making of unique, creative costume image with modem sense and adding artistic value on crochet knit wears. As for the contents and method of this study, We analysed formative aspects of Gustav such as line, color and shape Klimt in his art, and reviewed the cases where his works had been employed in modern costume. The conclusions are as follows; First, painting is important motif for contemporary costume design, and according to the individual thinking and expression, can be a major momentum for development of original design. Especially the organic lines and decorative patterns of Gustav Klimt paintings were suitable for rich decorative motif of costume design. Second, the unique colors of Gustav Klimt paintings can, if introduced to costume, allow new color combination. Third, crochet technic, by the texture of material, can present rich expression even with the basic knitting only. The embroidery metallic thread which is the main material for this study, was good for expression of gorgeous and classy image, in spite of the difficulties from its typical luster and embossed feeling. And the mohair, used as decorative motif, allowed more three dimensional expression with its rich voluminous and tangling property. Fourth, in applying Gustav Klimt paintings to costume design, other technics such as knitting, beading, applique, and patchwork helped creation of more unique clothes, presenting possibilities of rich artistic expression.

  • The objective of the present study was to estimate genetic parameters for economic traits in Markhoz goats. Data collected from 1993 to 2006 by the Markhoz goat Performance Testing Station in Sanandaj, Iran, were analyzed. The traits recorded as body weight performance at birth (BW), weaning (WW), six month (6MW), nine month (9MW), yearling (YW) and yearling fleece weight (YFW) were investigated. Least square analyses were used for estimation of environmental effects. Genetic parameters were estimated with single and multi trait analysis using restricted maximum likelihood (REML) procedures, under animal models. By ignoring or including maternal additive genetic effects and maternal permanent environmental effects, five different models were fitted for each trait. The effects of sex, type of birth, age of dam and year of birth on the all body weights were significant (p<0.01), but had no effects on YFW except year of birth. Age of kids had significant influences on WW and 6MW (p<0.01). A log likelihood ratio test was carried out for choosing the most suitable model for each trait. Total heritability estimates for YFW and growth traits varied from 0.16 for YFW and WW to 0.41 for YW. For all traits, maternal heritability was lower than direct heritability, ranging from 0.06 for BW to 0.01 for 6MW and 9MW. The magnitude of $c^2$ was more substantial for BW than the others, and relative importance was reduced from 0.12 for BW to 0.04 for 9MW. The direct additive genetic correlations estimates were positive and varied from 0.21 between BW-YW to 0.96 between WW-6MW. Direct additive genetic correlations between YFW and body weight traits were positive and ranged from 0.14 between BW-YFW to 0.67 between 6MW-YFW. For all traits, the corresponding estimates for phenotypic correlation were positive and lower than genetic correlations. The maternal additive genetic correlations between various traits were varied and ranged from -0.19 between 9MW-YFW to 0.96 between 6MW-9MW. The estimates of the maternal permanent environmental correlations between various traits were positive and ranged from 0.33 between WW-YFW to 0.93 between WW-6MW. Also, the environmental correlations between various traits ranged from 0.01 between BW-YFW and WW-YFW to 0.70 between 9MW-YW. Estimates of genetic parameters for various traits in this study confirm that selection should be applied on WW for genetic improvement in Markhoz goats.

  • This study was aimed at evaluating the effect of red-yeast-rice supplementation on cholesterol-lowering and glucose control in subjects with impaired fasting glucose (IFT) or impaired glucose tolerance (IGT). We conducted a doubleblind, placebo-controlled study with 3 groups; placebo, low dose group (red yeast rice 210.0mg/capsule, 2.52g/day) and high dose group (red yeast rice 420.0mg/capsule, 5.04g/day), which were randomly assigned to subjects with impaired fasting glucose or impaired glucose tolerance. We measured fasting serum concentrations of total-, LDL-, HDL-cholesterol, triglyceride, glucose, insulin, free fatty acid (FFA) and 2 h oral glucose tolerence test (OGTT) before and after the supplementation. Both low dose and high dose groups had significant decrease in LDL cholesterol and atherogenic index (AI) compared with placebo group (p<0.05). Additionally, total and HDL cholesterol improved significantly in high dose group compared with placebo group (p<0.05). Fasting serum glucose decreased in test groups and increased in placebo group after intervention. However, it was not significant differences. In subjects which fasting blood glucose is more than 110mg/dL, fasting glucose had a tendency to decrease in high dose group (p<0.1) and Hemoglobin A1c (HbA1c) had significant decrease in low dose group (p<0.05), while insulin and HOMA-IR had a tendency to increase in placebo group after intervention. Mean changes of glucose related parameters (fasting glucose, insulin, HOMA-IR) compared with placebo group did not show significant differences. In conclusion, subjects with impaired fasting glucose or impaired glucose tolerance were significantly improved in serum lipid profile by red yeast rice supplementation without serious side effects. These are more effective in the case of a high dose. The effects of red yeast rice supplementation on glucose control were insignificant.
