The purpose of this study was to investigate the result of a market research on men's jacket in their age of 25 to 35, who wear fitted jackets most, and to examine the comparative analysis of pattern and the wearing evaluation between classic jacket and fitted jacket. The results are as follows; Firstly, according to the results of a market research, 32.0% of the target owned fitted jackets, and 28.7% expressed their desire to buy only fitted jackets. This means their concern and preference for fitted jacket with which they could show up young, fresh and slim look are as high as those for classic jacket. Secondly, classic jacket showed the higher value than fitted jacket in such items as chest girth, waist girth, hip girth, sleeve's hem girth, jacket length, shoulder length, side seam length, and across shoulder point length. On the other hand, fitted jacket showed the higher value than classic jacket in back armhole length, front length, collar point length and sleeve's vent length. Thirdly, classic jacket was larger than fitted jacket in 1/2 chest girth(1.0cm), 1/2 waist girth(2.0cm), 1/2 hip girth(1.0cm), back width(0.5cm), front width(0.5cm) and side width(1.0cm). However, fitted jacket was higher than classic jacket in the armhole depth(0.5). Fourthly, the results of appearance evaluation revealed that there was a significant difference in 6 items. In other words, classic jacket was evaluated more appropriate than fitted jacket in such items as back width, back length, back neck depth, chest girth, waist girth and hip girth. And the fitted jacket had a higher value than the classic jacket in shoulder angle item. Fifthly, In the functional evaluation, fitted jacket was evaluated more uncomfortable than classic jacket. And this means that fitted jacket doesn't have a proper ease amount in each part and it has a high armhole depth compared to classic jacket. Therefore, for more comfortable patternmaking of fitted jackets, it would be required a pattern design which reflect men's own shoulder lines and women designers' flexibility that will satisfy both appearance and function.

N-acyl taurates are known as environmental-friendly and non-irritating to skin. In this study, the physicochemical properties of N-acyl taurates, which are amide-type anionic surfactants, were measured and also compared with sulfate-type anionic surfactants that show low biodegradability and are highly irritating to skin. The possibility of replacing the currently existing sulfate-type surfactants by N-acyl taurates was examined. Based on the experimental results, shampoos were formulated with these anionic surfactants and their stability and properties were measured. The possibility of application of amide-type surfactants to personal care cleaner was evaluated. Experimental results show that N-acyl taurates have various favorable aspects in making personal care cleanser: high viscosity, low surface tension, and low CMC values. These properties of N-acyl taurates generate nano-scale particles in emulsion, which is stable due to its high viscosity. This emulsion also has good cleaning ability with small amount of usage due to easy penetration into contaminants. Shampoo with N-methyl oleyl taurate showed high yield point and constant viscosity, and formed stable emulsion with nano- scale uniform particles. These results suggest that N-acyl taurates play an important role in making stable Interior structure in shampoo, and which improves the storage property.

We investigated the physicochemical properties of Ganjang added to a medicinal herb extract (functional Ganjang). 1be proximate compositions of conventional Ganjang (control) and functional Ganjang (supplemented with 3% or 5% of an hem extract) were not significantly different Analysis of total and free amino acids indicated 17 different amino acids in both types of Ganjang. Glutamic acid was the most common, followed by valine, leucine, isoleucine, lysine, methionine, phenylalanine, and threonine. Sensory tests of conventional and functional Ganjang found no significant differences. An analysis of flavoring components indicated that flavor-active compounds (paeonol, senkyunolide A, and cnidilide) were present in both forms of Ganjang. Our results suggest that the extract could be used to manufacture fermented soybean products.

This study investigated the effect of tea fungus/kombucha beverage(TF) protein concentrations and enzyme activities in serum of both normal and diabetic male rats. Sprague Dawley growing rats were randomly assigned to one control and five diabetic groups. In five diabetic groups, D control group was fed drinking water and the other groups were fed drinking water supplemented with 20 or 40% TF (20 or 40% TFD group, respectively) and 20 or 40% disinfected TF(20 or 40% TFSD group, respectively) for 7 weeks. Diabetes was experimentally induced in all five diabetic groups by streptozotocin injection after 3 week feeding. The diabetic groups were significantly decreased the body weight( 29.4~ 48.6g) compared with those in control group(72.4g). The total liver and kidney weights in all diabetic groups were similar to those in control group, but those relative to body weights in all diabetic groups were heavier than those in control group. The total spleen weight in all diabetic groups was significantly decreased compared with those in control group, but those relative to body weights in all diabetic groups were similar to those in control group. The blood glucose levels were heigher in all diabetic groups than those in control group. The alkaline phosphatase activity in serum was higher in all experimental groups than those in control group, but it was lower in 40% TFD, 20% and 40% TFSD groups than those in D control group. The GPT activity was significantly increased in D control, 20% and 40% TFD groups than in control group. The GOT activity was significantly increased in D control goup than in control group, but those in all TFD and TFSD groups were similar to control group. The total protein concentration in all diabetic groups was significantly decreased compared with that in control group, but the albumin concentration showed almost the same levels in all the experimental groups. The ratio of albumin/globulin, and hem atocrit value were significantly increased in all diabetic groups than in control group. These results show that tea fungus/kombucha beverage with which diabetic rats were fed has not recovered the decreased body weight, lowered serum total protein level, hypertrophy of liver and kidney, hyperglycemia to the normal state.

The objective of the study is was investigate the condition of the battle dress uniform worn by male members of the Korean Police Special Weapons Attack Team(KP-SWAT), identify problems, and provide basic raw materials for developing improved design of BDU. For this purpose, the researcher conducted a questionnaire survey on 92 male members of SWAT (Special Weapon Attack Team) units in Seoul using a questionnaire developed through observation and interview. Also, the body sizes of male SWAT members were measured. According to the results of body size measurements, male SWAT members generally require uniforms with a target bust girth, armhole, biceps circumference, thigh and calf circumference, longer jacket length, sleeve length, and trouser length to the knee. According to the results of the questionnaire survey, they reported dissatisfaction with the fit. In addition, they said that the Pockets are positioned too low for convenient use. Many subjects reported that their trousers were too short because of the rubber rings at the bottom of the legs. In addition, many subjects requested the alteration of the inconveniences caused by the designs finished with velcro on the bottom collar of the upper uniform, the marks and ensigns of the upper uniform, the bottom of the upper and lower uniform, and several pockets. Furthermore, there were many complaints concerning how they had to wear their uniform. The most frequently worn out and the body parts most often injured in field training and operations, they were reported, on the upper uniform, as the elbow, collar, neck, armpit, shoulder, and sleeve hem in that order, and on the lower uniform, the knee, interior calf, waist (belt rings), buttocks (rear pockets), and the bottom of the trousers (ankle) in that order As for questions concerning priorities in the improvements of the operational uniform and preferred design, the subjects recommended improvement in safety (protectiveness), workability (motional flexibility), design (shape), fit (size), comfort, ease in terms of putting on and taking off, etc., and the majority preferred two-piece designs ($67.4\%$), followed by one-piece ($30.4\%$), or both ($2.2\%$).

Immature zygotic embryos of five Korean soybean cultivars cultured on Murashige and Skoog's (MS) medium supplemented with various concentrations of 2,4-Dichlorophenoxyacetic acid (2,4-D) produced somatic embryos without forming an intervening callus. The highest frequency (up to 90%) of somatic embryo formation was obtained when zygotic embryos were cultlued on medium containing 1 to 2 mga 2, 0-D in four cultivars. However the frequency was highly variable to the cultivars. Transversely sliced primary somatic embryo halves were also capable of forming secondary embryos at frequencies of up to 70% when cultured on medium containing 0.1 to 1 mg/L 2,4-D. Somatic embryos formed on zygotic embryos cultured on medium containing 0.1 to 0.2 mg/L 2,4-D had two cotyledons more frequently than one horn-type cotyledon and those on medium containing 0.5 to 4mg/L 2,4-LD had a horm-type cotyledon at a prominently higher freequency. However somatic embryos on medium containing 10mg/L or higher concentrations of 2,4-D were usually shunted at the globular stage even after transfer to medium containing lower concentrations of 2,4-D or other growth regulators. non somatic embryos with one or two cotyledons or a hem-type cotyledon were transferred to medium containing $GA_3$, those with two cotyledons converted to plantlets at a higher frequency (25%) than the others.

Induction of twinning was attempted by transfer of two whole- or demi-embryos in Holstein cows and heifers. Cows were superovulated with follicle stimulating hormone(FSH) administered twice daily in intra-muscular injection. On day of 6.5 to 7 post-estrus, embryos were collected nonsurgically, Normal morulae and early balstocysts were obtained from superovulated cows. The embryos were hisected with a micro-blade made from a razor. Twenty seven pairs of half embryos were successfully produced and 23 pairs of half embryos were transferred to recipients( Group A). Twenty cows were treated with low unit of FSH (3mg${\times}$2,2mg${\times}$2 ; Group B1, 2mg${\times}$2, 1mg${\times}$2, 1mg${\times}$2 ; Group 32) to induce double or triple ovulations. The cows of Group B1 and B2 were Inseminated artificially(A1) at following estrus. Twenty four heifers were bred by A1 and received an additional embryo into the uterine horn contralateral to the corpus luteum(CL) 6 days later(Group C). One embryo was transferred into each uterine hem of 16 heifers 6 days after estrus(Group D). Fourteen heifers were received two embryos into the uterine horn ipsilateral to the CL at day 6 of estrous cycle(Group I). Pregnancy rates at 60 days in Group A, B1, B2, C, D and E were 34.8％, 70.0％, 60.0％, 66.7％, 62.5％ and 57.1％, respectively. Twinning rates were 8.7％, 20.0%, 10.0％, 16.7％, 18.7％ and 21.4％, respectively. The present experiments demonstrate that FSH treatment( Group 31) and ipsilateral transfer( Group I ) of two whole-embryos are more useful methods to produce twins than the others.

Sapphire single crystals have been highlighted for epitaxial gallium nitride films in high-power laser and light emitting diode (LED) industries. Among the many crystal growth methods, the Kyropoulos process is an excellent commercial method for growing larger, high-optical-quality sapphire crystals with fewer defects. Because the properties and growth behavior of sapphire crystals are influenced largely by the temperature distribution and convection of molten sapphire during the manufacturing process, accurate predictions of the thermal fields and melt flow behavior are essential to design and optimize the Kyropoulos crystal growth process. In this study, computational fluid dynamic simulations were performed to examine the effects of the crucible geometry aspect ratio on melt convection during Kyropoulos sapphire crystal growth. The results through the evolution of various growth parameters on the temperature and velocity fields and convexity of the crystallization interface based on finite volume element simulations show that lower aspect ratio of the crucible geometry can be helpful for the quality of sapphire single crystal.
