The purpose of this study was to examine the effect of covering yarn's twist on mechanical properties of knitted fabrics of composite yarns with single covering process. Four yarns that were used in this study: two different composite yarns made from the four kinds of cotton and functional polyester-(Poly-A) with the ratio of 52:48, and the rest two yarns are the original cotton 100% yarn and the poly-A 100% yarn. The two kinds of composite yarns, CP1 and CP2, were processed on the single covering process. CP1 was applied on the single covering process with S-800 tpm, where Poly-A was used as covering yarn and cotton was used as core yarn. CP2 was applied on the same process as CP1 except that Poly-A had been applied on the two-for-one twisting process with S-400 tpm on the previous step. Sixteen mechanical properties of all the four knifed fabrics knitted under the same knitting conditions were measured by KES-FB system with the outer knit condition. And 3D CAD dressmaking simulations, which were driven by some of the mechanical properties, were presented. The results were as follows: CP2 had high RT values with twisting of covering yarn. CP2 also had high B, 2HB values because of higher linear density. SMD was affected rather by twisting of covering yarn than by fine hair of the cotton surface. Twisting of covering yarn made it decreasing T value and increasing W value. Dressmaking 3D CAD simulations showed that there are buckling effects on CP2 because of high bending rigidity and shear rigidity.

Fur garment has long been the conventional symbol for luxury, or conspicuous consumption. However, as fashion items began to diversify as part of overall fashion trend, fur items are now more about individual taste and style than just lavishness. Synthetic fur is especially emerging as a new promising fashion material, with a touch almost like natural fur at an affordable price. Along with the emergence of 'Vegan Fashion' trend, synthetic fur is establishing itself as a popular fashion textile. This study is an attempt to investigate subjective evaluation and physical properties of natural and synthetic furs, whose results will further serve as basic data in developing synthetic fur materials. Sensory and emotional evaluations are carried out on natural and artificial furs. For analysis, factors such as weight, thickness, air permeability, gloss and compressibility were surveyed to observe how they influence the physical properties. According to the subjective evaluation, natural and artificial fur samples do not differ in conspicuous ways in appearance. Experiments on physical properties, specifically warm/cool touch experiment, show that natural fur has a slightly higher warm sensation than artificial fur. Luster analysis by using a microscope revealed that there are subtle qualitative differences between natural and artificial fur. During the subjective evaluation, subjects found it hard to state distinct quantitative differences in luster. A survey as a means of assessing qualitative differences in gloss seems to be necessary to complement the evaluation. Results from this study will potentially serve as resources for diversification of fashion product designs using synthetic fur.

Effects of four kinds of phosphate complex on the water holding capacity(W.H.C) and protein solubility of yellow-corvenia(Pseudosciance manchurica) and hair tail(Trichurus lepturns) meat paste were investigated. The formulations of four kinds of phosphate complex employed to this experiment were made by mixing several phosphates such as sodium polyphosphate, sodium pyro-phosphate, sodium acid pyro-phosphate, potassium pyro-phosphate, sodium tetra meta-phosphate, sodium ultra meta-phosphate and sodium hexa meta-phosphate, and monoglyceride at different mixture ratios. Among the four kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium poly-phosphate 50%, sodium pyro-phosphate 20%, sodium tetra meta-phosphate 20%, sodium acid pyrophosphate 5% and sodium ultra meta-phosphate 5% was most effective on enhancing the W.H.C and protein solubility of yellow corvenia meat paste, and in case of hair tail meat paste, phosphate C complex which was formulated by mixing sodium poly-phosphate 40%, sodium pyro-phosphate 30%, potassium pyro-phosphate 15%, sodium tetra meta-phosphate 10%, and sodium hexa meta-phosphate 5% was more effective than other phosphate complex, and their optimum addition level was 0.4% respectively in weight of fish meat paste. Texture characteristics such as hardness, cohesiveness, and springiness value of Kamaboko(fish meat paste product) were evaluated as best when 0.3% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 45 minutes at 85$^{\circ}C$.

The purpose of this study was to examine the correlation between physical properties of dried coacervate films and dry feel for shampoo composition. Simple shampoo compositions were made of two different cationic charge density polymers in the same surfactant compositions. The simple shampoo compositions were diluted with distilled water to make coacervate. Formed coacervate was collected by centrifuge (3,000 rpm, 30 min). Coacervate was coated on the glass plates and dried in drying oven (for 1 h, $50^{\circ}C$) to make the thin film. We carried out an experiment on measurement of contact angle, moisture loss ratio and SEM image analysis of the dried coacervate film. Dry feelings of the shampoos were evaluated by panel using hair tresses. Results show that the properties of dried coacervate films affect the dry feel of the after shampooing.

The purpose of this experimental study was to investigate the material properties of concrete surface preparator with inorganic composite, which was modified with plaster and admixture. A series of experiment were conducted to appraise the properties according to KS F 4716. The experimental results were as follows ; When the concrete surface preparator with inorganic composite was used, the hair crack and split, due to early drying shrinkage, was little. So it is superior to concrete surface preparator with cement paste plaster The bonding strength of concrete surface preparator with inorganic composite increased about 60% compared to that of concrete surface preparator with cement paste plaster. The workability of surface flatness and finishing was superior compared to that of existing concrete surface preparator. All specifications on concrete surface preparator were satisfied in the series of this experiments. Therefore, the concrete surface preparator with inorganic composite might be satisfactory applied in field due to its superior material properties.

This paper is a study on the Bisotun relief of the Achaemenid Dynasty in ancient Persia. The Bisotun relief consists of the relief and the inscriptions which was completed through 7 phases. The inscriptions describe how King Darius suppressed the rebels in Elamite, Babili and ancient Persian languages. This relief is a work during the early Darius period and it describes using the traditions of Mesopotamia in terms of the theme and structure. In terms of structural features, it follows the typical features of the Assyrian arts, the beard and the shape of hair style. On the other hand, the smooth curves used to describe the creases of the clothes and the supple body was not a typical oriental feature. It was known to be because of Greek influence from their communications. It also showed the dressings of the clans that made up the Achaemenid Dynasty through the 9 rebellions wearing clothes unique to their clan and the inscription that was inscribed with the name of the clans. The clothing and ornaments they were wearing can be divided into two groups, the clans that wore one-piece style Persian dress and clans that wore tunic jackets and trousers which is a typical dressing style of the nomads.

Cadmium ($Cd^{2+}$) is a heavy metal and a potent carcinogen implicated in tumor development through occupational and environmental exposure. However, the auditory effect of $Cd^{2+}$ is not poorly understood. The purpose of the present study was to investigate whether prevent the ototoxic effects of $Cd^{2+}$ by antioxidnat in auditory cell line, HEI-OC1. Rosmarinic acid is a naturally occurring phenolic compound and also known to possess marked antioxidant properties. We showed that antioxidnat inhibited the the cytochrome c release induced by $Cd^{2+}$. In addition, we showed that the regulatory effect of antioxidnat on apoptosis is through the caspase-9 activation, and extracellular signal-regulated kinase activation in auditory cells. These results suggested antioxidnat its therapeutic usefulness, against $Cd^{2+}$ induced activation of caspase-9 and ERK.

This study was conducted to investigate chemical properties, quality stability and utilization of approved sardine surimi(ASS) which is developed our laboratory. The product yield of the ASS was about 3 times higher than that of usual sardine surimi(SS). The proper addition concentration of sodium bicarbonate was 0.1% for the neutralization of the ASS. The content of salt soluble protein nitrogen in the ASS was about the half of that in the SS, while the content of water soluble protein nitrogen was 2.4 times higher in ASS. The total amount of free amino acids in the ASS was about 11 times higher than that of the SS. Predominant free amino acids in the ASS were histidine, taurine, glutamic acid and alanine, and those four amino acids occupied 94% of total amount of free amino acids. During cold storage at 21oC for 6 months, the quality of ASS was more stable than that of SS in judging from changes of water soluble and salt soluble protein nitrogen, AV and POV. Quality of fish burger, fish sausage and fried fish paste processed in accordance with commercial processing preparation using the ASS or SS exclusively and mixtures which other white meat fish surimi(alaska pollack, hair tail and sole) were proportionallly added to each of two types of sardine meat were evaluated. In case of fish burger, the product processed from the ASS only were superior.

Red ginseng oil (RGO), rather than the conventional aqueous extract of red ginseng, has been receiving much attention due to accumulating evidence of its functional and pharmacological potential. In this review, we describe the key extraction technologies, chemical composition, potential health benefits, and safety of RGO. This review emphasizes the proposed molecular mechanisms by which RGO is involved in various bioactivities. RGO is mainly produced using organic solvents or supercritical fluid extraction, with the choice of method greatly affecting the yield and quality of the end products. RGO contains a high unsaturated fatty acid levels along with considerable amounts of lipophilic components such as phytosterols, tocopherols, and polyacetylenes. The beneficial health properties of RGO include cellular defense, antioxidation, anti-inflammation, anti-apoptosis, chemoprevention, hair growth promotion, and skin health improvement. We propose several molecular mechanisms and signaling pathways that underlie the bioactivity of RGO. In addition, RGO is regarded as safe and nontoxic. Further studies on RGO must focus on a deeper understanding of the underlying molecular mechanisms, composition-functionality relationship, and verification of the bioactivities of RGO in clinical models. This review may provide useful information in the development of RGO-based products in nutraceuticals, functional foods, and functional cosmetics.
