This research is to observe background of origination and process of changing style for men's suits and also to observe the root of aes-thetics which has made the changing style be maintained for nearly 200 years. The aesthetic characteristics are 1)The revival of the Neo-Classicism beauty in the 18th century could be regarded as the root of incipient style of the modern men's suits design. And the cutters recreated ancient nude hero which was an object of envy at that time and also reproduced men's suits through modifying the existed suits to make the ancientnude conform with the sewing regulations in order to describe and convey the perfect image of gender,. 2) The cutter who pursued merit of the classicismic aesthetics in the late 18th cen-tury artistically upgraded English rough country coat to keep pace with Nordic coat style of netherland Russia Germany while in constrast with the coat style mode which was in fashion in France and Italy then And also they changed the English country coat to a noble natural clothing structure in relation to ancient sculpture to keep the English tradition. 3) Im the 18th century Neo-Classicism art emphasized transparent and monochromatic beauty and thus color was limitedly used. In the use of the limited color however ancient aesthetical simple purity was well described within the more realistic outline. In those days the cutter who admired the English neo-Classicism removed color-luster and preferred colorless finished dimly and transparently. And thus color of the men's suits become to be also dim colored in los brightness. This means that it did not express pure beauty but brought such effect of the Classicism beauty that the nude itself was figured out.

This study* 1) historically considered the meaning of light which has frequently wed as the subject of artistic expression since Renaissance, in order to grasp an artistic atmosphere about light and rays before the allusion of Rayonism. non it inspected closely the course of changes of light as a result of historic circumstances and intended to understand how Rusian Rayonism of the 20th, which maintained these effects of light more rationally, had an influence on modern fashion. It was created by Mikhail Larionov and developed by his wife, N. Goncharova. The main special feature of Rayonism wag the crossing of reflected ras, emerging from various objects. Most of these things depended on line and color. Re purpose of Rayonism paintings was to create a new space from arising from which reflected rays from various selected objected crossed one another. Namely, artists maintained that they should give up various objects of visible world and express rays which were reflected objects and crossed in complex. Rayonists were affected by Cubism and Futurism and came to fake an interest in relations whose rays of parallel or convergent color made, also in expression of themes. Since that, Rayonsim affected Supermatisme and Constructivism. Re pursuit of light and rays from the 19th until the early 20th came to appear in fashion as well as in art as it was. As Rayonists created a new space from which reflected rays from selected objects crossed one another, they used line and color as the main techniques of expression. in this way the attempt which intended to express rays, using itself of the line and color, appeared as futile design of tots of designs like Donna Karan, Cianni Versace and Rococo Barocco and so on of Modem fashion. This was designed for essential elements of pure art to express the new aestheic consciousness through fashion.

We present a new photometric study of the globular cluster NGC288 in Stromgren u, v, b, y, and H$\beta$ system. This cluster is known to have an intermediate metallicity but its color-magnitude diagram has a pure blue horizontal branch, which is a signature of metal poor stellar population. We compare our dataset with Bergbusch's (1993) in both field size and CMD to see whether different photometry system would determine the same physical parameters of a cluster. Demarque and Yi's isochrones (1996, private communication) were applied to Bergbusch's dataset, and we obtained distance modulus of (m - M) = 14.9 $\pm$ 0.2, color excess of E(B - V) = 0.03, and age of 1.5$\pm$3 Gyr. Vandenberg's (1985) isochrones for Stromgren system were also applied to Bergbusch's and our data. We find that the isochrone fits to different photometric systems give rather in consist ant solutions. The source of this discrepancy may become clear when the Demarque and Yi's isochrones for Johnson system are converted to those of Stromgren system. We note that Kurucz model atmospheres provide a useful ground for this conversion work as well as theoretical study of Stromgren characteristics of globular cluster stars.

The recent fashion trend of knit wear is now changing to the various fibrous color combination which emphasizes the plain texture. It supports the human body curvature which is influenced by the slim style of woven wear. In this research work, the general characteristics and knit wear fashion trend are studied. The metallic fiber and fancy yarn are used widely as fiber materials for knit in nowadays. However, the light and functional materials are preferred. The general characteristics of knit which gives the feeling of light and warm are still prevailing using pure wool, kid mohair, and mixed wool with polyester. In order to provide the soft touch feeling, smoothness of fine fiber, and feeling of sponge, several kinds of finishing techniques such as bulky, felting, bonding, and quilting process are usually adopted. The knit wear fashion trend is mainly consisted of the basic design items, and it gives the feeling of luxurious and elegance. The more youthful feeling is adapted for the general style of knit wear of the certain target age. The woven wear trend such as season color, line and pattern are applied in knit wear trend in recent days.

Molecules always show broad absorption band envelopes, and this results from the vibrational properties of bonds. The width of an absorption band can have an important influence on the color of a dye. A narrow band imparts a bright, spectrally pure color to the dye, whereas a broad band can give the same hue, but with a much duller appearance. Typically, half-band widths of cyanine dyes are about 25nm compared to value of over 50nm for typical merocyanine dyes. Thus, cyanine dyes are exceptionally bright. The factors influencing the width of an absorption band can be understood with reference to the Morse curves. The width of the absorption band depends on how closely the bond order of the molecules in the first excited state resembles that in the ground state. We have quantitatively evaluated the "molecular structure-absorption band shape" relationship of dye molecules by means of Pariser-Parr-Pople Molecular Orbital Method(PPP-MO).

The SrS:Cu, Ag thin film electroluminescient devices were fabricated on $AlTiO_3$/ITO/glass substrates by electron-beam evaporation. The emission spectrum of the device was about 460 nm with $\chi$=0.20, y=0.29 in the CIE color coordinator. It was found that the emission spectrum was saturated to pure blue color when Ag sensitizer was doped in SrS:CuCl phosphors. The luminance of the device was increased by increasing the sulfur pressure. The measured luminance was saturated with 430 cd/$m^2$at the applied voltage of 90 V and the maximum luminance was 580 cd/$m^2$at 110V. The polarization charge and conduction charge of the devices were found to be found to be about $3.5\mu$C/$\textrm{cm}^2$ and $7.4\mu$C/$\textrm{cm}^2$, respectively.

The white-light-emitting organic LED with two-wavelength was fabricated using blue emitting material(DPVBi) and a series of orange color fluorescent dye(Rubrene) by vacuum evaporation processes. The basic structure of white-light-emitting OLED was ITO/NPB(150$\AA$)/DPVBi(150$\AA$)/Alq$_3$:Rubrene(150$\AA$)/BCP(100$\AA$)/Alq$_3$(150$\AA$)/Al(600$\AA$). The changes of the CIE coordiante strongly depended on the doping concentration of Rubrene and the thickness of NPB layer. We obtained the white-light-emitting OLED close to the pure white color light and the CIE coordinate of the device was (0.315, 0.330) at applied voltage of 13V when the doping concentration of Rubrene was 0.5wt% and the thickness of NPB layer is 200$\AA$. At a current of 100mA/$\textrm{cm}^2$, the quantum efficiency was 0.35%.

A high NIR-reflective black pigment is developed by Mn doping of Fe2O3. The pigment powders are prepared by spray pyrolysis, and the effect of the Mn concentration on the blackness and optical properties is investigated. Mn doping into the crystal lattice of α-Fe2O3 is found to effectively change the powder color from red to black, lowering the NIR reflectance compared to that of pure Fe2O3. The pigment doped with 10% Mn, i.e., Fe1.8Mn0.2O3, exhibits a black color with an optical bandgap of 1.3 eV and a Chroma value of 1.14. The NIR reflectance of the prepared Fe1.8Mn0.2O3 black pigment is 2.2 times higher than that of commercially available carbon black, and this material is proven to effectively work as a cool pigment in a temperature rise experiment under near-infrared illumination.
