  • This paper studied the materials of the furniture which the noble men used in Goryeo, based on the furniture material category of solid wood furniture, lacquerware inlaid with mother-of-pearl and hardware. As for the solid wood furniture, the wood and furniture types are inferred based on the documents. The trees used for the wood furniture were zelkova, korean willow, pine, royal paulownia, maidenhair tree, korean pine, chinese juniper and elm. The furniture types were table, chair, wooden bench, small portable table, writing table, and folding screen. As to the types of lacquerware inlaid with mother-of-pearl, most of them were hams with top, which were made of abalone shells. The features of the lacquerware inlaid with mother-of-pearl were in detail and elaborate like the pattern of the full bloomed chrysanthemum. Writing tables were also made of lacquerware as pieces of furniture. Distinctively, the mother-of-pearl furniture material was popular enough to be used even in a horse saddle. Regarding the metal feldspar used as both a practical use and decoration, there are drop handle, hinge, the front basis, and lock seen in the artifacts, which were made of cast iron, bronze, and brass. Their manufacture techniques were eojamoon, bratticing and sheet metal. Through this study of the furniture materials used in Goryeo, it seems that Goryeo furniture focused on the functions rather than on the decorations, and in turn the forms were simple and basic. The technique of mother-of-pearl, a bit elaborate one, was used in the props furniture like kitchen wares, hams, or writing talbes. Probably, the solid wood is inferred to be used in a low wooden bench, a chair, and a table based on the documents.

  • Molecular simulation is an exceptionally useful method for predicting self-assembled structures in various macromolecular systems, enlightening the origins of many interesting molecular events such as protein folding, polymer micellization, and ordering of molten block copolymer. The length scales of those events ranges widely from sub-nanometer scale to micron-scale or to even larger, which is the main obstacle to simulate all the events in an ab initio principle. In order to detour this major obstacle in the molecular simulation approach, a molecular model can be rebuilt by sacrificing some unimportant molecular details, based on two different perspectives with respect to the resolution of model. These two perspectives are generally referred to as 'atomistic' and 'mesoscopit'. This paper reviews various simulation methods for macromolecular self-assembly in both atomistic and mesoscopic perspectives.

  • The purpose of this study is to examine the characteristics that appeared in the fashion and colors of exotic tastes used by Renoir with a view to re-evaluating his-attitude towards exotic tastes. The methods used in this study were literature research and analysis of visual data from Renoir's works. The results of the study are as follows. Renoir's exotic tastes originated from the material perspective appearing in the fashions and accessories of Algeria, Orient, Spain, and Japan. Parisienne Odalisque Lise in Harem-style, Jeanne Samari in parisienne fashion holding a Japanese fan, and Gabriel in oriental fashion were portrayed as major muses. The Algerian style consisted of white, yellow or red veils, thobes, loose pants worn in Haik, and burnous. The Oriental-style was composed of harem pants, turbans, hair accessories, ornate zouave jackets, and oriental ornaments. The Spanish-style showed gay ornaments, fitted red or yellow matador costume, red bandannas, black hats, and red dresses, plus Spanish guitars. The Japanese-style consisted of kimonos, accessories such as fans, and backgrounds with interior articles such as vases, wall picture frames, and folding screens. The exotic fashion colors were red, yellow and white. Renoir expressed the works with his delicate skills and sense of craftsmanship, and he even added creative design portrayals sometimes. He selected fashions and accessories of exotic tastes as objects and expressed the objects with materials and colors reflecting regional characteristics as such, he can be regarded as an artist wed to who fashions of exotic tastes.

  • To provide functional properties in fish paste, Styela plicata (Korean name: omandungi) having antioxidant and anticarcinogenic activity was added at 0, 5, 10, 15, and 20%. The fried fish pastes were investigated for color, textural properties, and sensory attributes. Fish paste containing 15% S. plicata showed the lowest values in lightness (L) and the highest values in redness (a) and yellowness (b). All test samples with 3 mm thickness had good flexibility and did not break even after folding 4 times. Fish paste containing 20% S. plicata showed the highest values in strength, hardness, and adhesiveness. In overall acceptance of sensory evaluation, fish paste containing 15% S. plicata acquired the highest score. These results support that S. plicata can be applied to fish paste products for the purpose of high quality and functionality.

  • Bicycle riders complain of many inconveniences when wearing glasses, sunglasses and masks. The disposable fine dust mask has been developed to resolve such inconveniences of bicycle riders. The scope of research is limited to the fiber which generates one-time static electricity and the shape of the mask due to the characteristic of fine dust mask. The purpose is to design and make the fine dust mask with a simple production process. The new disposable fine dust mask has secured enough space of the mask in front of the mouth by longitudinal folding and minimized stuffiness by maintaining the shape of the folded part to prevent touching the mouth even by heavy breathing. The streamlined sponge is attached at the part of nose support and the area of the cheek has been expanded to be about 2.5cm wider than ordinary masks to improve tight seal at the side. In addition, a new disposable fine dust scarf mask has been developed to block ultraviolet rays for the face and neck while filtering fine dust with the tight fine dust mask.

  • According to the result of the experiment, except that Oebal Hanji making, which does not consider the fiber orientation, has a smaller difference between its strength of width and length direction than of Ssangbal Hanii making, there is not a significant difference between Oebal Hanji making and Ssangbal Hanji making. In addition, even though Oebal Hanji making produced indigenous technique is generally felt sturdy because its absolute strength is enhanced by applying fine materials and overlaying several sheets of paper, its relative strength, which is expressed in an index, is not far beyond that of Ssangbal Hanji making Study on the effect of Dochim revealed that Dochim improves remarkably folding endurance and enhances breaking length and the burst strength. Especially, Dochim increase tensile strength. It was also revealed that, indigenous Oebal Hanji making, the higher the number of sheets of paper overlaid is, the higher the tear strength is the increase relatively higher than those of other types of strength. Consequently, Dochim treatment greatly reinforces the imperfect strength of indigenous Hanji. We consider that if we apply Dochim treatment to Ssangbal Hanji making it may bring about abnormal imbalance of strength. We can benefit from the characteristic strength of Oebal Hanji making only when performing paper making and Dochim considering fiber orientation.

  • This study is to formulate strategy for subject who are selected as national team in horizontal bars event in apparatus gymnastics. For this, skill training program was applied to players for 8 weeks. Then it was analyzed by using 3D motion Analysis system to seek the difference between before and after using the program. There were decisive demerit element K's first try for Tkatchev stretched movement from low elevation and crooked body while elevating. Not only, the location of his center of mass is far and low and there was some concern in his landing due to bended his hip-joint, but also, it exposed weak point in retro-action followed technique. Thus, to overcome that weak point, the subject repeated practices on following; when preparing for Tkatchev stretched movement at downward for big spin, make sure extend shoulder angle faster, make sure Tap movement is short and concise using hip-joint angular while delaying Tap timing for folding the body, and moreover, while backlashing the body, used shoulder joint angle wide to pull up the body. As a result, the speed of vertical upward did rut increase when separation from the bar. However, height of elevation increased that the leg would rut hit the horizontal bar even straight up the hip-joint. Therefore, the movement itself provided magnificent motion and even helped decrease the demerits.

  • The present experiments proposed to pass judgement upon the suitability as the second intermediate host of Clonorchis sinensis, of three kinds of fresh-water fish by having them infected with the cercaria of Clonorchis sinensis and then observing the penetrating ability of the cercaria, and maturity, the process of degeneration and extinction, and infectivity of the metacercaria of Clonorchis sinensis. The following is a brief summary of the leading facts gained through the experiments; 1. P. parva was easily subject to invasion of the cercaria, A. signifer was much less subject to the invasion, and finally A. asmussi was hard to invade. And the infectivity of the cercariae was in proportion to their penetrating ability mentioned in the above. 2. The examination of the cercariae after having three kinds of fresh-water fish infected with them disclosed that 24 hours after the infection, all of the cercariae formed their cysts in muscle and the metacercariae kept growing, and that 7 days later the metacercariae were found folding their bodies twice, and that in 15 days the characteristic structure of the metacercariae was complete and they made a vigorous rotary movement intermittently. 3. Then the metacercariae came to a state of maturity and beyond this stage some metacercariae in P. parva started the process of degeneration and extinction in 133 days; some in A. asmussi, in 140 days; and A. signifer, in 70 days. As more days elapsed, their degeneration and extinction increased in number, and in 269 days all of them in A. signifer became dead while those in A. asmussi were all dead in 460 days. However almost all of them in P. parva survived even after 770 days. The results shown above revealed that P. parva was the most suitable as the second intermediate host among three kinds of fresh-water fish and that A. signifer and A. asmussi were not quite recommendable as the second intermediate host. The ability of the cercaria to invade fresh-water fish, and life span of the metacercaria within fresh-water fish vary outstandingly according to species of fresh-water fish. An explanation as to the mechanism must wait as the subject to be further pursued.

  • It is not rare that pseudotachylite, dark colored rock with glassy texture, is recognizable in deep core samples drilled up to 900 m from the surface. Pseudotachylite with widths varying few to 20 cm is sharply contacted or interlayered with the host rocks composed of Jurassic granite and Precambrian amphibolite gneiss, showing moderately ductile deformation or slight folding. Pseudotachylite occurring at varying depths in the deep drill core are slightly different in texture and thickness. There is evidence of fault gouge at shallower depths, although brittle deformation is pervasive in most drill cores and pseudotachylite is identified at random depth intervals. Under scanning electron microscope (SEM), it is evident that the surface of pseudotachylite is characterized by a smooth, glassy matrix even at micrometer scale and there is little residual fragments in the glass matrix except microcrystals of quartz with embayed shape. Such textural evidence strongly supports the idea that the pseudotachylite was generated through the friction melting related to strong seismic events. Based on X-ray diffraction (XRD) quantitative analysis, it consists of primary minerals such as quartz, feldspars, biotite, amphibole and secondary minerals including clay minerals, calcite and glassy materials. Such mineralogical features of fractured materials including pseudotachylite indicate that the fractured zone might form at low temperatures possibly below $300^{\circ}C$, which implies that the seismic activity related to the formation of pseudotachylite took place at shallow depths, possibly at most 10 km. Identification and characterization of pseudotachylite provide insight into a better understanding of the paleoseismic activity of deep grounds and fundamental information on the stability of candidate disposal sites for high-level radioactive waste.

  • Styela clava (Korean name: miduduk) tunic was produced as a byproduct after processing of S. clava. To utilize S. clava tunic, fish paste containing tunic powder was prepared, and quality characteristics were evaluated for color, textural properties, and sensory attributes. Increasing the amount of S. clava tunic in fish paste tended to decrease lightness (L), redness (a), and yellowness (b) values of the surface part of fish paste. Strength and hardness of fish paste increased with increasing amount of tunic. All test samples with 3 mm thickness showed good flexibility and did not break even after folding in half four times. For overall acceptance in the sensory evaluation, fish paste containing 1% S. clava tunic acquired a relatively higher score. These results suggest that S. clava tunic can be applied to fish paste products to improve quality and functionality.
