PURPOSE. The objective of this study was to evaluate the clinical acceptability of all-ceramic crowns fabricated by the digital veneering method vis-$\grave{a}$-vis the traditional method. MATERIALS AND METHODS. Zirconia specimens manufactures by two different manufacturing method, conventional vs digital veneering, with three different thickness (0.3 mm, 0.5 mm, 0.7 mm) were prepared for analysis. Color measurement was performed using a spectrophotometer for the prepared specimens. The differences in shade in relation to the build-up method were calculated by quantifying ${\Delta}E^*$ (mean color difference), with the use of color difference equations representing the distance from the measured values $L^*$, $a^*$, and $b^*$, to the three-dimensional space of two colors. Two-way analysis of variance (ANOVA) combined with a Tukey multiple-range test was used to analyze the data (${\alpha}$=0.05). RESULTS. In comparing means and standard deviations of $L^*$, $a^*$*, and $b^*$ color values there was no significant difference by the manufacturing method and zirconia core thickness according to a two-way ANOVA. The color differences between two manufacturing methods were in a clinically acceptable range less than or equal to 3.7 in all the specimens. CONCLUSION. Based on the results of this study, a carefully consideration is necessary while selecting upper porcelain materials, even if it is performed on a small scale. However, because the color reproducibility of the digital veneering system was within the clinically acceptable range when comparing with conventional layering system, it was possible to estimate the possibility of successful aesthetic prostheses in the latest technology.

This study focused on Jungchimak (coats with side slits) which was typically worn by men in the mid and late Joseon Dynasty. It was done research by examining the case of wearing Jungchimak centering on literature and paintings and analyzing its changes in terms of its form based on the relics that have been found in order to suggest the standard for the evaluation of the period of Jungchimak. Results are as follows. First, men who wore Jungchimak were the king, crown prince and Aristocratic under the official uniform or other robes or as ordinary clothes and shroud. Second, Jungchimak for king was mostly made of Dan (satin damask) and mostly jade green & navy in color, and it commonly used dragon pattern, cloud and treasure pattern, or grape pattern. The fabric used to make Jungchimak for crown prince was Dan & Ju (coarse-finished silk) and puple, green, jade green & navy in color. The fabric used to make Jungchimak for Aristocratic was Ju and indigo or white in color. Third, 251 relics have been announced until now. Most of them were made of silk fabric and had cloud and flower patterns. Fourth, Jungchimak showed changes through time in terms of collar and sleeve shapes, the ratio of armhole to sleeve opening, Geotseop (panel sewn on front opening for overlapping), Dang and Mu (side panel), the ratio of the total length of outer collar to the length of side slits, and the ratio of chest size to the width of lower end.

The air-flow dyeing machine is a new type of dyeing machine. Which is an energy saving type to be able to dye the fabrics with the lowest liquor ratio and in shorter time. This machine is operated with an aerodynamic system rather than a hyd raulic system for traditional jet or overflow dyeing. An air-flow dyeing machine(Green-flow) by the use of aerodynamic technology was developed and compared with the Luft-roto machine made by Thies Company, Germany, in this study. Three samples were dyed with both machines under the same dyeing conditions and color fastness, dyeing levelness, drapability, and mechanical properties of these samples were compared. The results were as follows; Both machines have almost the same dyeability. The dyeability was good at liquor ratio of 1: 3.5 and the speed of 450yds/min. The order for drapability was Crepe de Chine > Cool Peach > Charmeuse. Except for the color fastness of sublimation being below class 4, most color fastness of samples dyed with Green-flow m/c were above class 4. The maximum speed was 510yds/min. for Crepe de Chine and the standard deviation of K/S value was lower for Charmeuse and Cool Peach when employed on the "Green-flow" machine and lower for Crepe de Chine when employed on the Luft-roto machine. Comparing with dyeing of the Green-flow machine and that of the Luft-roto machine, the RT of the Charmeuse was found to be higher with the Green-flow machine and thus the sample had an improved wrinkle recovery. LT and WT of Cool Peach were higher, and shear properties(G, 2HG, 2HGS) of Crepe de Chine were higher, both turning out as suitable for clothing. clothing.

Purpose: This study aims to develop menu for tofu, which will satisfy a variety of needs of people by harmonizing tofu and other ingredients. Methods: In the present study, the standard recipes were made for tofu menu development by improving the existing recipes like Dubu-seon, Dubu-kimchi, Dubu-jeongol, and Sundubu-jjigae (soft tofu stew). Based on newly developed recipes, the nutritional analysis was conducted using the analyzing program of the Korean Nutrition Society (CAN-Pro 4.0). Food styling was devised considering the shape and color of plates, layout, and color harmony. Table design was devised empirically employing tablecloth, napkin, dinnerware, glasses, cutlery, centerpiece, and figures. Results: Food styling of Dubu-seon was devised by improving the visual aspect, using Korean traditional five cardinal colors. It turns out that the improvised version of Dubu-seon (prepared following the new recipe) can satisfy 15.1% of amount of recommended dietary fiber intake per day for both male and female adults. In case of Dubu-kimchi, the dish was developed as a one-dish meal by supplementing protein and improving food styling. Beef was added in a form of a meatballs which is especially preferred by children. However, the amount of salt was reduced due to the strong and spicy taste of kimchi itself, resulting in 32% of daily intake of sodium. Dubu-jeongol was also improvised by reducing protein content, and more vegetables were added. Food styling was also improved. Concerning Sundubu-jjigae, protein was supplemented by addition of mushrooms rather than the existing way of adding shellfish. The sodium content was 133.88 mg, which is merely 10% of daily intake. Conclusion: With the new developments in tofu menus, new food styling, and table design, this study aims to contribute towards the rise in sales in the food service industry in terms of being used as basic and critical data.

About 70 high redshift quasars with $z{\geq}5$ have been discovered through combinations of standard broad-band filters to distinguish them from contaminating sources. However, among the discovered quasars so far, there is a redshift gap at $5{\leq}z{\leq}6$ due to the limitation of traditional filter sets and selection techniques. To understand the early mass growth of supermassive black holes and the final stage of the cosmic reionization, it is important to find a statistically meaningful sample of quasars with various physical properties. Here we suggest a new selection technique of high redshift quasars using medium-band filters: nine filters with bandwidths of 50nm and central wavelengths from 625 to 1025nm. Photometry with these medium-bands traces the spectral energy distribution (SED) of a source, similar to spectroscopy with R~15. We installed these filters to SED camera for QUasars in EArly uNiverse (SQUEAN) on the 2.1m telescope at McDonald Observatory, and conducted test observations of known high redshift quasars at $4.7{\leq}z{\leq}6.1$ and also dwarf stars for comparison. We found differences in SED shapes between high redshift quasars and dwarf stars, determined their locations on color-color diagrams, and demonstrated that the medium-band filters can enhance the efficiency of selecting robust quasar candidates in this redshift range. In this poster, we propose an effective selection method of high redshift quasars using these medium-band filters and discuss its effect on our high redshift quasar survey.

Objectives : The purpose of this study was to analyze the trend of clinical research on quantitative indicators of Mibyeong in traditional chinese medicine(TCM). Method : The journal search was performed using china national knowledge infrastructure(CNKI) database. Our inclusion criteria were as following: TCM clinical researches for quantitative indicators of Mibyeong. Exclusion criteria were as following: non-TCM clinical researches, used intervention methods. Results : Eleven clinical researches were analyzed in this study. Four of these researches classify the Mibyeong as a type of pattern identification(PI) and studied the characteristics of the PI quantitative indicators. Mibyeong diagnosis was done through guidelines and questionnaires, each was used at a similar rate. Quantitative indicators mentioned in the selected researches were blood indices, nailfold capillary, complexion, color of tongue substance and coating, pulse wave diagrams and heart rate variability. Among them, seven researches related to blood indices were the most. Blood indicators include whole-blood viscosity, plasma viscosity, fibrinogen, packed cell volume(Hct), triglycerides, total cholesterol, HDL-C, LDL-C, glucose, BUN/CREA, luteinzing hormone, estradiol, follicle stimulating hormone, IgA, IgG, etc. Conclusions : Based on this results, in combination with western medicine, it seems necessary to try to interpret the Mibyeong in more various ways. Even if the same Mibyeong, it is necessary to identify the index which changes according to the PI or chief complaint, and to set the Mibyeong standard corresponding thereto.

As an attempt to view Chason costume from a aesthetic perspective, the aesthetic values of the Choson people, as expressed through the aesthetic characteristics of costumes, are pursued in this study. To appreciate the beauty of the traditional Korean costume, the following aesthetic characteristics of Choson costumes are investigated: form, color, pattern, material and ornament. From the view point of aesthetics, this study shows that Choson costume had comfortable and voluminous forms with beautiful curved lines and rhythm. The most favored colors were white and natural colors of materials. However unusual combination of colors such as the contrast of black and white, the harmony of the primary and rainbow colors were often used. Patterns revealed two aspects : while subdued patterns generally prevail, at times the unexpected beauty of primary colored patterns draws our attention. Smooth natural materials were preferred. Ornaments both for practical and decorative purposes were used together with certain colors and patterens, indicating wearer's status and warding off the evil's spirits. The aesthetic values in costumes as expressed through the aesthetic characteristics can be classified into the following categories: the beauty of nature, the beauty of personality, the aesthetics of evil's eye and the beauty of tradition. The beauty of nature, as appreciated by the Chason people through their prevailing nature, the "Pung-rew Spirit" and through their Worship of Heaven, produced aesthetic characteristics in harmony with nature. The beauty of personality influenced by the ethical standard of Confucianism produced aesthetic characteristics in costumes, through which the appropriate personality was shown for the appropriate social status. On the other hand, the aesthetics of evil's eye, rooted deeply in Folk religion and Shamanism, contributed to various aesthetic characteristics, which strongly inclined to sorcery and symbolism through choice of patterns, colors and ornaments. Finally, the beauty of tradition, which was based on the ethics of Confucianism and the Choson people's conservative tendencies, demonstrated the strong tendency to adhere to the external characteristics of the Choson costume. These aesthetic values were the yardsticks of the aesthetic judgment of the Choson people. These values influenced Chason people in designing costumes and in appreciating the beauty of costumes. The aesthetic experience and attitudes of the Chason people, which were based on these aesthetic values, represented their aesthetic consciousness and desires.
