The purpose of this study was to identify the change and characteristics of 20th men's fashion. The result of the Study as follows; 1 In the period 1890's-World War I there was a display of opulence and extravagance Therefore men's fashion pursued with elegance and grace. The rise of sports and an erosion of rules of Victorian society were evident influences before 1914. So men's silhouette resembled athletic appearance and less formality was shown in masculine attire. 2. During the period World War I-1920's the new equality of social relations between the sexes had an influence in fashion. Unisex look evolved so boyish shaped became the feminine ideal, men wanted to boyish fitted leaner stylings and natural shoulder suits. In the twenties youth, who seemed to have a social dominance, asserted their own testes in fashion. New style of men's fashion such as oxford bags and Ivy League Look appeared. After World War I "comfort" is the aim of fashion so casualness was reflected in fashion: vests often were discarded and man wore a soft, detachable collars. 3. In the thirties depression marked a shift in mood from gaiety and progressivism of the twenties to the conservative, even reactionary values. The role of men and women returned to more traditional attitudes, Every men's general appearance was bold and manly: his chest was broad and well-built, his shoulders square and muscular. The effects of World War ll were not on style but on textiles and clothing construction: lighter weight fabrics appeared and construction was simplified 4. Men's dress changed only in detail and not in essence. But there was a continued increase in the variety of clothes and color in men's fashion.

This study identifies the dimensions of cosmetics consumption values and the differences in cosmetics brand selection through a cosmetics consumption value group and by product type. The subjects of the study were females over age 20 living in Seoul and Gyeonggi Province between January and February 2008; 427 questionnaires were used for analysis. For data analysis the SPSS 17.0 statistical program was used, and principal component analysis, factor analysis using Varimax rotation, Cronbach's ${\alpha}$ reliability testing, cluster analysis, ANOVA test, and Duncan test were conducted. The results and conclusions of this study are as follows. The dimensions of cosmetics consumption values were found to be the pleasure value, the fashion value, the function value, the brand ostentation value, and the appearance ostentation value. Five types of groups by factor were identified: the group seeking function, the group seeking fashion and brand ostentation, the group seeking pleasure, the group seeking appearance and brand ostentation, and the indifferent group. Second, The group attaching importance to functionality was more likely to select high-priced brands while the group attaching importance to brand awareness were more likely to seek foreign brands, irrespective of product type. As far as base and color cosmetics are concerned, the group attaching importance to pleasure was more likely to select low, medium, and high priced foreign brands, as well as low and medium priced domestic brands. As for body products, the group attaching importance to fashion and brand awareness tended to select low, medium, and high priced domestic brands, as well as high priced foreign brands. By simultaneously purchasing high, medium, and low priced brands, these groups display an ambivalent consumption pattern. This study identified the differing dimensions around cosmetics consumption values and cosmetic brand selection. The research findings helps cosmetic companies set product prices and contributes to cosmetic marketing strategies.

This study proposes a pixel-patterning method for organic light-emitting diodes (OLEDs) based on thermal transfer. An infrared lamp was introduced as a heat source, and glass type donor element, which absorbs infrared and generates heat and then transfers the organic layer to the substrate, was designed to selectively sublimate the organic material. A 200 nm-thick layer of molybdenum (Mo) was used as the lightto-heat conversion (LTHC) layer, and a 300 nm-thick layer of patterned silicon dioxide (SiO₂), featuring a low heat-transfer coefficient, was formed on top of the LTHC layer to selectively block heat transfer. To prevent the thermal oxidation and diffusion of the LTHC material, a 100 nm-thick layer of silicon nitride (SiN_x) was coated on the material. The fabricated donor glass exhibited appropriate temperature-increment property until 249 ℃, which is enough to evaporate the organic materials. The alpha-step thickness profiler and X-ray reflection (XRR) analysis revealed that the thickness of the transferred film decreased with increase in film density. In the patterning test, we achieved a 100 ㎛-long line and dot pattern with a high transfer accuracy and a mean deviation of ± 4.49 ㎛. By using the thermal-transfer process, we also fabricated a red phosphorescent device to confirm that the emissive layer was transferred well without the separation of the host and the dopant owing to a difference in their evaporation temperatures. Consequently, its efficiency suffered a minor decline owing to the oxidation of the material caused by the poor vacuum pressure of the process chamber; however, it exhibited an identical color property.

An organic light-emitting diode(OLED) has advantages of low power driving, self light-emitting, wide viewing angle, excellent high resolution, full color, high reproduction, fast response speed, simple manufacturing process, or the like. However, there are still a number of challenges to get over in order to put it to practical use as a high performance display. First of all, the most important thing is to improve the efficiency of the OLED element in order to commercialize it. To this end, its efficiency can be improved by lowering the driving voltage through the improvement of structure of the OLED element and the application of new organic substance. Therefore, in this study, we have manufactured a red OLED element by applying fluorescent dyes to the emitting layer of the element having the structure of ITO/TPD/ Znq2+DCJTB /Znq2/Al and the structure of ITO/CuPc/NPB/ Alq3+DCJTB/Alq3/Al, in order to light-emitting various colors or improve the brightness and the efficiency, and then we have evaluated its electrical and optical characteristics.

The electrochemical properties of 9-methyl-2,3,6,7-tetramethoxyfluorene have been investigated by cyclic voltammetry in acetonitrile, dichloromethane, trifluoroacetic acid (TFA) and trifluoroacetic acid anhydride (TFAn). The first charge transfer for the compound in $CH_3CN$ appeared to be a quasi-reversible one-electron step. The second oxidation step from cation to dication was irreversible. However, the oxdition of the compound in a mixture of solvents containing $CH_2Cl_2$, TFA and TFAn was reversible for both the first and second charge transfer reactions. Since the electrolytic products display a darkblue color and can be stabilized in the solvent mixture, they may be used as an electrochromic material.
