  • As a result of making an inquiry into the ethnic look of each region appearing in present-day fashion by Asia. America and Oceania. Africa and Europe as mentioned above, its characteristics could be summarized as follows: Firstly the Asian ethnic look consists of Indian, Chinese and Japanese looks as mainstream. In terms of form, the draped form constituted its mainstream, and both the draped form and the tunic form are appearing Simultaneously in the Chinese look. And in respect to color the Indian look is using luxurious primary colors red, blue, yellow and green and other regions are making overall use of natural colors. With respect to ornament various kinds of ornaments is utilized in Indian's Sari and turban. Chines's Coolie hat, straw hat and embroidery, knotted button, and bead ornament, and Japan's Obi and Obijime, etc. Secondly in America and Oceania, costurme representing the Indian look in North America and the picture of Western pioneer, and the Peruvian, Mexican and chilean ethnic looks in South America were expressing much. Here, the form consistied a draped form as its main strem, such colors as yellow, purple, grey, etc were much utilized, and the material of costume comprised knits, cotton and the like. And the ornament consisted of hats, tassel ornaments, bead ornaments, metal chain belt, long braided hair, etc. Thirdly, the African ethnic look had an exposing form and a draped form, and such colors as black, white, yellow, brown, etc were used as the fashion color. Ornaments such as precious stone, bead ornaments, animal bones, straw metal ornament, etc were used as fashion decorations. Fourthly, Russia's Cossack look, Bulgaria's Bavshika look, spain's ethnic look cane to the fore as the European look Both the draped form and the tunic form were used simultaneously as fashion form. And grey, brown, purple, etc were much used as fashion color in the European look. Such ornaments as Cossack. Bavshka, boots, tassel ornaments were much used and paisley pattern also was used.

  • The appearance of many Glass Fiber Reinforced Plastic (GFRP) constructions look like ordinary steel construction, because GFRP has been imitated by the same way with the traditional steel's cross section as well as connection system. In terms of detachable connection, there was not enough appropriate option of GFRP connection, such as a traditional bolt connection for steel and wood structures. Most of all, from material characteristic of GFRP related to the deficient ductility, the shearstress principle of GFRP s not proper for the material property, which causes ineffective and not economic application of material. With this research problem, the innovative and detachable onnection system, which is more considered with appropriate material characteristic for FRP, is developed. Not only short time but also long time research with various connection variations is carried out.

  • The position of the thermodynamic equilibrium for reverse thermochromic spiropyran 6-carboxylates (SP-COOHs) was easily determined in aqueous binary mixtures, such as water-methanol, water-acetonitrile and water-dimethyl sulfoxide. The existence of more than one type of interconvertible species of the ring-opened form of SP-COOH in aqueous binary solvents enables us to evaluate the molar extinction coefficients of the ring-opened species of SP-COOH and to obtain the thermodynamic parameters.

  • In this article, an efficient and simple refined theory is proposed for buckling analysis of functionally graded plates by using a new displacement field which includes undetermined integral variables. This theory contains only four unknowns, with is even less than the first shear deformation theory (FSDT). Governing equations are obtained from the principle of virtual works. The closed-form solutions of rectangular plates are determined. Comparison studies are carried out to check the validity of obtained results. The influences of loading conditions and variations of power of functionally graded material, modulus ratio, aspect ratio, and thickness ratio on the critical buckling load of functionally graded plates are examined and discussed.

  • It is important to have a well developed strain energy function in order to understand the mechanical behavior of biomaterial like the blood vessel of artery. However, since it is not possible to have a complete form of strain energy function of artery, theoretical framework describing the behaviour of Rubber-like material which is similar to blood vessel is applied to infer useful forms of strain energy function of biomaterial. Based on Chuong-Fung model and Mooney-Rivlin model, material parameters are estimated based on experimental data. From the results, it can be inferred that the estimated parameters can be used to explain the difference of mechanical characteristics between normal vessel and vessel with stent.

  • Effects of temperature dependent material properties on mixed mode fracture parameters of functionally graded materials subjected to thermal loading are investigated. A domain form of the $J_k$-integral method including temperature-dependent material properties and its numerical implementation using finite element analysis is presented. Temperature and displacement fields are calculated using finite element analysis and are used to compute mixed mode stress intensity factors using the $J_k$-integral. Numerical results indicate that temperature-dependency of material properties has considerable effect on the mixed-mode stress intensity factors of cracked functionally graded structures.

  • This paper is a study for the computerization program of incoming and outgoing processes of a number of parts and a great amount of material for producing products in flood industry, which was required by a medium-sized company located at Cheon-An. The program consists of four databases, one main form, seventeen subforms, and eight report forms. Concretely speaking, the four databases are prepared for products, semi-products, material, and reports, and the seventeen subforms are those for current inventory, used quantity, safty stock, product specification, etc. With the program, users can be helped and save manpower, time and cost in incoming and outgoing processes of parts and material for producing products and in their real time operation and decision-making.

  • This paper discovers that there are some peculiar properties that can remove holography grating, which was made in chacogenide thin film by impressed voltage. The thin films were used are $As_{40}Ge_{10}Se_{15}S_{35}$, and we use He-Ne laser in order to form thin films. I-V curved line in a thin film before a lattice was made has the critical point, about 3.7 V. Moreover, the I-V curved line increased current intensity at over 4 V after it made thin film. In addition, while holography grating is being made, and when it has the highest diffraction efficiency, a lattice can be deleted if put more voltage into it.

  • The unequivocal solid-state structure and stereochemistry of the hetaryl leuco-TAM dye, 2,2’-(2-phenyl propane- 1,3-diylidene) bis(1,3,3- trimethylindoline) derivatives were established using X-ray single crystal analysis. The X-ray crystal analysis showed that the (Z, E)-isomers only formed stereoselectively, with a so-called “threebladed propeller” conformation, from the reaction of a Fischer base and benzaldehyde derivatives. These isomers were stacked in a juxtaposition to form a dimer or a double dimer, adopting either a triclinic, with P-1, or monoclinic crystal system with a space group P21/n in the unit cell of the crystal.
