  • Our country's fur clothing industry has rapidly grown for a short time since it started with simple needlework of fur pieces, and now it is still developing as export industry that some enterprises besides general business firm export more than ten million dollars a year. However, it is true that fur clothing industry is still in unsatisfactory level in its size and system, compared with manufacturing or leather industry. Of course, we import crude material and processed fur on an entire base, and we have few wild fur on an entire base, and we have few wild fur animals because of our natural condition and it is hard to breed them. On the other hand, the world's fur industry shows that the demand of fur clothes is increasing as fur animal breeding is improved and developed and supply has become rather abundant with the help of fur clothing fashion since late 19th century : Also, there is a trend that some developed countries depend on importing rather than self-prodoction because of the character-istic of labor-concetntraled fur industry. Accordingly, considering this situation, we can expect fur clothing industry as promising export industry by analyzing the present situation of our country's fur clothing industry and suggesting its problems and solutions, and here are developing plans for growing fur clothing industry as promising export industry. First, smoothing delivery of crude material. Second, making high quality products and diversifying goods. Third, establishing effective competition system in fur clothing industry. Fourth, raising skilled man power. Lastly, there should be coopetation among the related fields in the aspect of policy including the support from the government.

  • This investigation aimed at improving the quality of domestic Angora fur fibre, when it is spun together wool and synthetic fibre, by solving the difficulties in processing and it was also aimed at finding the methods of preventing the fault of fibre-slipping off from knitted goods. This investigations was classified into two main parts, one of them was fundamental study and another was spinning and knitting performance. In the former the physical and chemical properties was investigated, in the latter the spinning and knitting performances was investigated taking use of the results of fundamental study. The processing aspects was, in the study of spinning and knitting performance, compared with the quality of trial-products which was made during the investigation and the method of preventing fibre-slipping off was also studied. Summary of results were as follows; 1) Topology of Angora fur fibre \circled1 Generally Angora fur fibre was classified into three appearances, finer fur fibre, hetero type hair and guard hair. \circled2 Angora fur fibre, regardless of its appearances, was composed of ladder type medulla forming a hollow cylinder and covered with cortex. \circled3 A few crimps was founded in Angora fur fibre except finer fur fibre. \circled4 Though the scale on the Angora fur fibre was founded, it was exceedingly by smaller than that of woo. 2) Physical properties \circled1 Because of characteristics in appearances of Angora fur fibre the strength-elongation behaviour was considerably scattered and load-elongation behaviour of finer fur fibre was less than that of wool. \circled2 The static charging rate of Angora fur fibre was similar to that of wool but discharging rate was quicker than that of wool. \circled3 The staple length of domestic Angora fur fibre was considerably scattered. 3) Chemical properties \circled1 The chemical component of Angora fur fibre was similar to that of wool. \circled2 Rate of curl was increased by the treatment of carroting but the load-elongation behaviour became 4) Spinning and knitting performance \circled1 Smaller amount of water was recommanded when oiling the Angora fur fibre than oiling the wool. \circled2 The processing characteristics of Angora fur fibre was similar to that of wool which has fine denier and long staple. \circled3 Knitting officiency could be increased by the use of additional filament yarn. 5) Fibre-slipping off from the knitted goods \circled1 The mechanism of fibre-slipping off was classified into two parts, fibre-slipping off by statics and frictional pulling. \circled2 a) The prevention of fibre-slipping off was capable by increasing of twists, turns Per unit length of yarn and using of long staple. b) The use of core yarn was effected on the decrease of fibre-slipping off.

  • From the ancient Korea to the late Joseon Korean fur and leather had been preferred in and out of Korea for their good quality and excellent manufacturing skill. Since Unified Silla (A.D.676${\sim}$A.D.936) Korean fur and leather were manufactured divisionally by workmen specialized in materials and products, and such manufacturing process was succeeded to Goryeo and Joseon. Manufacturing of fur and leather was consisted of as follows: hunting and butchering - peeling - beating with a paddle and removing fat - oil manufacturing - drying - tanning, then cutting and sewing, and there was a special caring method. In order to make good fur and leather, each process of manufacturing needed particular techniques and all available methods were tried to have tender fur and leather by using smoking, excrement, lime, vegetable tannin and even cerebral liquid. And also required mouth-chewing and hand-pounding with a lot of time and of labor Keeping furs resilience and flexibility, sowing several skins together, even when the after-all-process skin was converted into clothes, was much more difficult than sewing fabric. Thus, the manufacturing cost was as much expensive as skin materials, and the volume of manufacturing of fur and leather was also limited. Therefore, fur and leather must have been popular for scarcity value in the manufacturing process, and this scarcity must have caused an extreme luxury of fur.

  • The purpose of this study is to investigate the Ku which was worn by nomadic tribes which was Khitai, Mongols and Manchus. The results of this study can be summarized as follows. 1. The fur clothes were very important clothes that nomadic tribes put on in order to protect them against the cold. The Ku was an outfit for protection against the cold. It was made of ani-mal fur and its style was tight sleeve and long dress. 2. The Ku was worn in all social classes including emperor, nobles and the masses in ancient China and Asia dynasty. After the nomadic tribes estabilished dynasty in China the style of Ku was changed. All kinds of animal fur was used to make the Ku but the volume of fur, kinds and colors were classified severely by their social position. In Khitai dynasty the Ku was worn in same style. But the emperor wore the Ku of silver marten. The noble class wore the Ku of purple, black and blue marten and silver squirrel skin. The masses wore the Ku of the other colors marten, sheep, squirrel and dessert fox skin. In Mongol dynasty, the emperor wore the Ku of purple marten, silver squirrel, silver fox and black fox skin. The nobles wore the Ku of the other colors marten and squirrel. The masses wore the Ku of degraded animal fur. Before the Manchus estabilished the varient races dynasty in China, the rich man preferred the Ku of marten, squirrel, fox, goat furs. But the poorman preferred the Ku of cow, horses, pig, sheep, cat, dog, snake and deer skin. After the manchus conquered the China, the manners of dress were changed. Generally the fur did not appear in right side of garment, but high quality or noble fur appeared outside. Sometimes the inside or outside of Ku was made of silk fabrics and sleeves, neck-band was made of the high quality fur.

  • This paper proposes an unified definition of powers for various circuit conditions such as balanced/unbalanced, sinusoidal/non-sinusoidal, and linear/nonlinear, fur single-phase systems and three-phase systems. Conventional reactive power is more classified into an interactive power and an alternating power. These powers are defined both in the time domain and the frequency domain consistently, and agree well with the conservation law. Several important power quality factors are defined to measure and evaluate the power quality fur the various circuits in the single-phase and three-phase systems. Simulation results show the power quality factors can evaluate and classify the various circuit conditions clearly.

  • The objectives of the study were to analyze the acoustic characteristics related to the internal quality factors of watermelon(Citrulus Vulgaris Schrad). Among the various internal quality factors, only four factors such as ripeness, inside cavity, yellow belt and blood flesh were considered in this study. Relationships between the internal quality factors, the day after fruit set and the day after harvest were also investigated. Test apparatus was the same as the apparatus described in the previous study(Choi et at., 2000). The selected sample was divided into four groups; 69 samples used for ripeness tests 56 samples for ripeness test along the day after fruit set and for yellow belt detection, 60 samples for ripeness along the day after harvest 44 samples fur blood flesh detection. It was shown that the first peak frequencies shifted to the lower range and the energy ratios of the bandwidths between 0∼550 Hz to the bandwidths between 850∼2500 Hz increased as the day after fruit set elapsed. Since the acoustic responses of the watermelon such as frequency and magnitude began to change from 10 days after harvest, the storage period of watermelon in a normal temperature condition seemed to be approximately 10 days after harvest. The ratios of the first peak amplitude to the maximum peak amplitude fur the sound watermelon showed the higher value than that fur watermelon with cavity inside, and the separation between the sound and cavity inside could be accomplished by the ratio value of 0.25. The energy ratios (0∼550 Hz/850∼2,500 Hz) for the watermelon with cavity inside showed the higher value than 2.3. The frequency characteristics of the yellow belt watermelon appeared mostly in the range of 600∼900 Hz frequencies. The yellow belt watermelon showing the energy spectral density function at this frequency range to be over 70 seemed to be not a marketable commodity, The energy ratios(0∼550 Hz/850∼2,500 Hz) for the blood flesh watermelon showed the higher value than 3.5.
