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.

The purpose of this study was to understand the labor division between men's housework and market work and to research the change of men's contribution to housework. And it was also examined what kinds of valuables work on a change in men's market work and housework. The information about men's change in the labor division was collected from the biggest 5 news papers in Korea for last five years for this study. And either men's new participation trend to household work did. Words searched for this study were men, labor, family, home, housewife, work, household work, father etc. Korean men have experienced a overloaded breadwinner role and have worked most in the world since 1960s. But Korean men's working time was continuously decreased a little every year. As Korean Companies had fired many worker during IMP economic crisis period, Korean men had to work more than before because of decreased fellows and they should have concentrated on their work at the sacrifice of private life and family-sharing time. On the other hand, some men were started to participate to do housework as a results of long-unemployment and early retirement after this periods. 5 day working system be in forced gradually since 2003 especially make men come back home and interest on housework. So Korean men's housework participation is gradually increasing by the practical application of sex-equitable politics such as 5 day working system and men's suspension regime for baby care. father's increased participation to children education and care, men's new family-oriented life style, dual-sexuality education system, and socially changed perception to husband housemaker. These interrelated trends demands us to shape a new labor division pattern in the family that make change the breadwinner/homemaker conception by the gender role. Now, all of family, men, women, and children have to join housework. It would help women, men, and all families make more human and equitable relationship.

본 연구에서는 국내 최초로 플라즈마 토치를 사용한 재(ash) 용융설비에서 발생한 슬래그를 대상으로 기존에 제시되지 않은 새로운 냉각방식(분체냉각방식)을 적용하여 현재 적용되고 있는 슬래그 냉각방법보다 적용성 및 부가가치를 높일 수 있는 냉각방식을 제시했다. 재료적 특성분석 및 토공재료로의 재활용 가능성을 검토하여 향후 공정 개발에 적용할 수 있는 방안을 제시하고자 한다. 소각재(ash)는 Y시의 fluidized bed method에서 배출되는 하수슬러지를 소각하여 실험재료로 사용하였다. 하수슬러지 소각 잔재의 XRF 분석결과는 $SiO_2$가 전체 32%로 가장 많은 비율을 차지하고 있으며, CaO, $Al_2O_3$, $Fe_2O_3$ 등이 주성분 원소로 구성되어 있다. XRD 분석결과에서는 냉각슬래그 입자로부터 전형적인 유리화 진행을 찾을 수 있었으며 냉각슬래그 분말로부터 크리스탈상이 관찰되었는데 그 이유는 분말이 녹지 않은 상태로 표면에 존재하기 때문이라 판단된다. EDX 분석으로부터 냉각매체로 사용된 전후에 분체의 성분이 바뀌지 않았으며 만약 다른 형태를 사용한다면 활용성이 더해진 분말을 생산할 수 있을 거라 판단된다.

In Ethiopia, dry land vegetation including the fairly intact lowland and western escarpment woodlands occupy the largest vegetation resource of the country. These forests play a central role in environmental regulation and socio-economic assets, yet they received less scientific attention than the moist forests. This study evaluated the woody plant species composition, population structure and carbon sequestration potential of the A. senegal woodland across three distance gradients from the settlements. A total of 45 sample quadrants were laid along a systematically established nine parallel transect lines to collect vegetation and soil data across distance gradients from settlement. Mature tree dry biomass with DBH>2.5 cm was estimated using allometric equations. A total of 41 woody plant species that belong to 20 families were recorded and A. senegal was the dominant species with 56.4 IVI value. Woody plant species diversity, density and richness were significantly higher in the distant plots compared to the nearest plots to settlement (p<0.05). The cumulative DBH class distribution of all individuals had showed an interrupted inverted J-shape population pattern. There were 19 species without seedlings, 15 species without saplings and 14 species without both seedlings and saplings. A significant above ground carbon (5.3 to 12.7 ton ha^-1), root carbon (1.6 to 3.6 ton ha^-1), soil organic carbon (35.6 to 44.5 ton ha^-1), total carbon stock (42.5 to 60.7 ton ha^-1) and total carbon dioxide equivalent (157.7 to 222.8 ton ha^-1) was observed consistently with an increasing of distance from settlement (p<0.05). Distance from settlement had significant and positive correlation with species diversity and carbon stock at 0.64^⁎⁎ and 0.78^⁎⁎. Disturbance intensity may directly influence the variation of species composition, richness and density along the A. senegal woodland. The sustainability of the A. senegal woodland needs urgent protection, conservation and restoration.

Brain tumors or gliomas are fatal cancer species with high recurrence rates due to their strong invasiveness. Therefore, the goal of surgery is complete tumor resection. However, the surgery is difficult to distinguish the border because tumors and blood vessels have the same color tone and shape. The fluorescein sodium is used as a fluorescence contrast agent for boundary separation. When the external light source is irradiated, yellow fluorescence is expressed in the tumor, which helps distinguish between blood vessels and tumor boundaries. But, the fluorescence expression of fluorescence sodium depends on the concentration of fluorescein sodium and such analytical data is insufficient. The unclear fluorescence can obscure the boundaries between blood vessels and tumors. In addition, reduce the efficiency of fluorescence sodium use. This paper proposes a protocol of concentration range for fluorescence expression conditions. Fluorescent expression was observed using a near-infrared (NIR) color camera with corresponding dilution using normal saline in 1 ml microtube. The flunoresence emission density range is 1.00 mM to 0.15 mM. The fluorescence emission begin to 1.00 mM and the 0.15 mM discolor. The discolor is difficult to fluorescence emission condition obserbation. Thus, the maximum density range of the bright fluoresecein is 0.15 mM to 0.30 mM. When the concentration range of fluorescein sodium is analyzed based on the gradient of fluorescence expression and the power measurement, the brightest fluorescence is expected to facilitate the complete resection of the tumor. For the concentration range protocol, setting concentration ranges and analyzing fluorescence expression image according to saturation and brightness to find optimal fluorescence concentration are important. Concentration range protocols for fluorescence expression conditions can be used to find optimal concentrations of substances whose expression pattern varies with concentration ranges. This study is expected to be helpful in the boundary classification and resection of brain tumors and glioma.

Objective : The purpose of this study was to analyze the foot-pressure distribution of 2D(2 dimensional form) & 3D(3 dimensional form; a customized arch-fit for posture correction) insoles for assessing their biomechanical functionality. Background : Recently there has been increased interest in both foot health and foot pain patients. Analysis of the plantar pressure was often used to solve the problems of the foot displayed by such people as rheumatoid arthritis patients. Method : Subjects who participated in this study were 17 female university students who had no previous injury experience in lower limbs and a normal gait pattern. The shoe size of all subjects was 240 mm. Two models of insoles of 2D(typical flat insole - 2 dimensional form) and 3D(special production - 3 dimensional form) were selected for the test. Using the Pedar-X system and Pedar-X insoles, 4.0 km/h of walking speed, and a compilation of 50 steps walking stages were used to analyze foot-pressure distribution. Results : Results of the foot-pressure distribution and biomechanical functionality on each insole were as follows; analyses of mean plantar pressure, maximum plantar pressure, maximum vertical GRF, and plantar pressure curve shape all showed overall low plantar pressure and GRF. Conclusion : This can be evaluated as an excellent insole for low levels on the plantar pressure and GRF. Therefore, it is possible to conclude that according to this analysis the 3D Customized Arch-fit Insole was better than 2D insole on the basis of these criteria.
