In the 20th century, The artistic world was constantly producing new ideas and movements and the world of fashion responded to and reflected them all in greater of lesser degree. Dress designers have always been aware of what is happening In the arts and have always been able to use the discoveries and ideas of the artist to help them solve design problems and create fashion which are new, inventive and reflective of thier time. Up to the present, other researchers have investigated the connections between the fine arts and the Modern Fashion. In this respect, the objective of this research was to clarify the characteristics of painting of the Impressionism on the Modern Fashion. In order to investigate the relationship between the trend of painting and Modern Fashion. Especially, Impressionism's light and color affected both 20th's painting and other sorts of art. That is, the trend of the modern painting, Fauvism, Cubism, Surrealism, Abstract art, Abstract Expressionism, was influenced by Impressionism painting. Similarly, in the sihouette, line, color, fabric pattern of the Modem Fashion was represented characteristics of the Impressionism Painting. The fashion's Fauve, Paul Poiret was excited by the power of color in the same intense way as the 'wild beasts' of art. The color of his clothes during that period was bold and brilliant. Gabrielle Chanel simplified the shape of women's clothes to a square cardigan and rectangular skirt. This was a cubist concept. Art and fashion probably held hands closest in the 1930s, when Elsa Schiaparelli was creating clothes directly influenced by the Surrealist thinking of Salvador Dali. And she burst upon the fashion world with a sweater that had a trompe I'oeil bow. Soma Delaunay was one of great pioneers of Abstract in. She proceeded to mix strong and bright colors into her art and created the geometric and abstract patterns of the clothes and fabrics with her strong color. The influence of Abstract Expressionism was expressed the fabrics of the Modern Fashion. Some fabrics used in Modern Fashion are printed in a dripping pouring and splashing style. For the future, some futher research to investigate the art-fashion connection might involve establishing systematic classifications for silhouette, line, texture, color of the fashion. Moreover, in order to study the influence of fine art on the fashion, a broader approach might wish to analyze the relationship between painting and other plastic arts.

This study was carried out to develop new hybrid zoysiagrass cultivar 'Seah' (The application no. for cultivar protection : 2014-22). Native zoysiagrasses were collected from south-west seaside of Korea from 2010 to 2011. Artificial crossing was conducted to develop F1 hybrid between Z2011 (Z. sinica) and NM1 (Z. matrella) at plastic house in 2011. Among the progenies, 'Seah' showed fine leaf texture and high shoot density from the space planting plots at field. 'Seah' showed genetically light green color, with fine leaf with 1.8mm and height to the lowest leaf blade was 1.94 cm. Ground coverage rate was slower than medium leaf zoysiagrass (Jung-gi), but plant height of 7.1 cm was the lowest among the compared zoysiagrasses and height to lowest leaf of 1.94 cm was lower than most zoysiagrass, which may allow low mowing height.

Microstructures and mechanical properties of SPSed monolithic HAp, HAp-Ag, and HAp-ZrO$_2$sintered bodies were investigated by the XRD, SEM, and TEM techniques. The nano-sized HAp powders were successfully synthesized by precipitation of Ca(NO$_3$)$_2$4$H_2O$ and (NH$_4$)HPO$_4$solution. In the HAp-Ag composite, the shrinkage cavities were observed at the interfaces between HAp and large sized Ag particles due to the mismatch of their thermal expansion coefficients. However, no found the defect at the interfaces between HAp and fine-sized Ag particles. In the HAp-ZrO$_2$composite. nano-sized ZrO$_2$particles were almost dispersed at the grain boundaries of HAp phase. The fracture toughness of HAp-Ag and HAp-ZrO$_2$ composites were increased due to the plastic deformation and phase transformation mechanisms of the dispersed fine Ag and ZrO$_2$phase in the HAp matrix, respectively.

Recently, issues related to the quality of concrete have continuously resulted in surface quality problems, such as the exfoliation of concrete surfaces due to the cost reduction of cement and poor quality fine aggregate, scaling of surfaces caused by laitance, and plastic shrinkage cracks. Prompted by social issues, the application of a photo catalyst to road structures is being attempted to solve the environmental problems caused by fine dust and automobile exhaust. In this study, chemical admixtures were developed to improve the surface quality of concrete and to apply and distribute titanium dioxide in nanoscale sizes to provide basic data for the development of a photocatalyst-curing agent. As a result of the experiment, silicon and silane were reviewed as a raw material as a curing agent to develop a high performance curing agent with better film performance than conventional curing agents because they could form a film quickly on a fresh concrete surface. The distributed stability of the ultrasonic disperser showed the best performance through an outdoor test for four weeks to review the dispersion measures for the application of nanomaterials.

CFRP chip is the byproduct from carbon fiber reinforced plastic (CFRP) processing. CFRP chip is not simply a waste mainly composed of fine carbon fiber and epoxy resin. CFRP chip keeps matrix to maximize their reinforcing effect. To obtain a uniform length of carbon fiber in CFRP chip, chip was chopped ina mortar. CFRP chip should be purified to get better interface adhesion. Epoxy resin on the carbon fiber was removed by $H_2O_2$ surface etching treatment. Optimal dispersion and fabrication conditions of CFRP chip embedded in phenolic resin were determined by thermal stability for fire retardant applications. CFRP chip-phenolic composite exhibits better mechanical and thermal properties than neat phenolic resin. Surface condition of CFRP chip-phenolic composite was evaluated by static contact angle measurement. Contact angle of CFRP chip-phenolic composite was greater than neat phenolic due to heterogeneous condition of fine carbon fibers. From the evaluation for fire retardant (ASTM D635-06) test, thermal stability of CFRP chip-phenolic composite was found to be improved with higher concentration of CFRP chip.

To improve the physico-mechanical characteristics of heavy clayey paddy soils(Hwadong series) on Diluvial terrace after application of fine sand and briquette ashes, barley and rice were cultivated for 2 years. The influences of sand and briquette ashes on soil properties and on the crops were summarized as follows: 1. Application of the adding materials could not affect the yield of rice but barley yields were increased significantly about 18-19% in the plots of sand 100t/10a(clay 15% adjusted) and in the plots of briquette ashes. 2. The porosity and the content of water stable aggregates were decreased in the plots of sand and briquette ash adding. The chemical properties were slightly decreased in the plots of sands while the contents of av. $SiO_2$: and extr K were increased in the plots of briquette ashes. 3. Soil mechanical properties such as cone penetration resistance, shearing resistance and plastic index etc. were decreased while the friction resistance increased in the plots of sand and briquette ash treatments. Consequently, the adaptability to mechanization was increased. 4. The content of rice roots in subsoils (10-20cm) were increased in the plots of sand and briquette ash treatments.

In this study, performance evaluation and rheological characteristics were analyzed for recycling the fine powder of nuclear power plant dismantled waste concrete as a solidifying agent for radioactive waste disposal. The radioactive concrete fine powder was used to prepare a simulated sample, and the test specimen was prepared using Di-water, CoCl₂, and 1 mol CsCl aqueous solution as mixing water. Regardless of the aggregate mixing ratio and the type of mixing water, it satisfies the performance standard of 3.45 MPa for compressive strength at 28 days of age. All specimens satisfied the criteria for submersion strength, and the thermal cycle compressive strength satisfies the criteria for all specimens except Plain-50. As a result of evaluating the rheological properties of the solidifying agent, it was found that the increase in the aggregate mixing rate decreased the yield stress and plastic viscosity. The leaching index for cobalt and cesium of all specimens was 6 or higher, which satisfies the standard. In order to secure the stable performance of the solidifying agent, it is considered effective to use 40 % or less of the aggregate component in the solidifying agent.

The degree of saturation determines the connectivity of void space and the particle surface. Thus, it greatly affects the electrical conductivity of soils. This study aimed to analyze the electrical conductivities of coarse grains with a high relevance of pore water conduction and fine grains with a high relevance of surface conduction based on the degree of saturation. It also aimed to express the electrical conductivity of unsaturated soils as a combination of surface and pore water conductions using the modified Archie's equation. Samples were prepared in a plastic cell equipped with four electrodes, and the electrical conductivity was measured based on the porosity at various degrees of saturation (40%~100%). The results demonstrate that Archie's equation can be used to express the electrical conductivity of coarse grains, with a saturation exponent of ~1.93 regardless of the pore water conductivity. However, the saturation exponent of fine grains varied considerably with pore water concentration. This variation can be attributed to the relative magnitude of surface conduction with respect to the electrical conductivity of soils at different pore water concentrations. Thus, the degree of saturation has varying effects on pore water conduction and surface conduction. Therefore, different saturation exponents must be used for pore water conduction and surface conduction to predict the electrical conductivity of unsaturated soils using the modified Archie's equation.

Warthintumor (WT), also known as adenolymphoma or papillary cystadenoma lymphomatosum, was described in 1895 for the first time. It is a common benign tumor of the parotid glands and the second most common neoplasm of the salivary gland, accounting for 5% to 14% of all parotid neoplasm. A 63-year-old man visited our clinic with the complaint of swelling on the right parotid gland. Physical examination showed a 3 cm, firm, well-circumscribed, painless mass on the right mandibular angle. Computed tomography imaging showed a $3.5{\times}2.0{\times}1.6$ cm well-defined cystic mass. WT is histologically characterized by bilayered, oncocystic cell, lymphoid stroma, and cystic space. With these typical cytomorphologic characteristics, the fine-needle aspiration cytology was performed as diagnostic tool before the surgery. The lymphocytes and oncocystic cell were not observed. The lesion was completely excised under general anesthesia. We diagnosed the case as WT, from the surgically excised specimen. We report on the case with a review of the literatures.
