The dyeability and colorfastness of browning extracts from mushroom were investigated. The results of this study are as follows, 1. Browning extracts from mushroom exhibited dyeability to wool, nylon and silk. The wool and silk had the greatest K/S value at pH 4 and nylon at pH 5 2. Furthermore, the increase in K/S value corresponded to temperature, time, and the number of dyeing. 3. In most cases, the value of K/S was increased by mordant treatment. The treatment of pre-mordant caused the increase in K/S value depending on the concentration of mordant, but not in the color. Co.mordant and post-mordant treaments, however, showed various colors of YR, Y, and GY types of Munsell color wheel. 4. In the most cases, color fastness of light, drycleaning, laundry, sweat, rubbing was excellent.

Synthesis and characterization of pigments by using $Fe_2O_3,\;CoO,\;Cr_2O_3\;and\;MnO_2$ were undertaken. The resulting pigments were characterized by using XRD, SEM, FT-IR and UV-Vis spectrophotometer. The color of glazed tiles containing 6 wt% pigment changed from dark green to black depending on the compositions of used materials. Pigments were calcined with mixed materials at $1350^{\circ}C$, and the dark green and dark brown color were obtained. Pigments were used to determine possible interactions between a pigment and a glaze.

Objectives: The aim of this study was to investigate the characterization of composite resin inlay surface with silane and non-thermal atmospheric pressure plasma treatment. Methods: Composite resin inlay was used as a specimen, which was treated by sandblasting + silane and sandblasting + plasma. The untreated specimens were assigned to the control group. Specimens were analyzed for surface roughness, color change, and chemical composition. Statistical analyses were performed using one-way ANOVA test (p<0.05). Results: The present findings showed that the roughness and color changes of the plasma-treated surface were significantly lower than those of the silane-treated surface. In addition, a change in the chemical composition was observed on the plasma-treated surface. Conclusions: Based on the results, non-thermal atmospheric pressure plasma could be a potential tool for the cementation of composite resin inlay.

This study examined the quality characteristics of yanggaeng with rice germ; it was incorporated into yanggaeng at different levels (containing 5% rice germ, 10% rice germ, 15% rice germ, and 20% rice germ) based on the total weight of red bean extracts. For analyzing the quality characteristics of yanggaeng, moisture content, hardness, color, antioxidant activity, total polyphenol content, reducing sugar, and vitamin E were determined. There was no significant difference in the moisture content and hardness except in the control. For color, lightness and yellowness of yanggaeng increased as the concentration of the powder was increased, whereas there was no significant difference in redness. As the rice germ powder was increased, total polyphenol content and antioxidant activity increased significantly, whereas reducing sugar decreased. Especially, total vitamin E, including isomers, increased as the concentration of the powder increased from 0.41 mg/100 g to 4.03 mg/100 g. Therefore, it could be possible to develop processed products with functional snack for yanggaeng prepared by adding 10% rice germ.

소형 LCD 디스플레이는 물리적, 전기-광학적 특성으로 인하여 표준 CRT의 색재현 특성과 많은 차이가 있다. 본 논문에서는 휴대폰용 소형 LCD 디스플레이에서 색 재현 특성 개선을 위하여 감마 및 CCT 보정 방법을 이용한 간단하고 실제적인 방법을 제안한다. 먼저 소형 LCD 디스플레이의 밝기, 균일성, 색온도, 화이트 및 블랙 밸런스, 비선형 감마 등의 특성을 조사하였다. 또한 입력 레벨에 따른 휴대폰용 LCD의 색 재현 영역 및 상관 색온도 (corresponding color temperature, CCT) 궤적을 분석하였다. 최종적으로 룩업테이블 방식을 사용하여 최적 감마 및 CCT 보정하는 방법을 제안하였으며, 제안된 방법을 휴대폰의 하드웨어를 변경하지 않고 구현하였다. 실험결과, 제안한 방법의 영상은 표준색에 매우 가깝게 재현되었다.

This study was conducted to prepare salmon patty using muscle separated from salmon frame (SPFM) and to investigate the food component characterization. When compared to salmon patty with fillet muscle (SPM), SPFM was lower in the moisture content, while it was higher in crude lipid content. However, no differences in the ash and protein contents between SPFM and SPM were found. Compared to SPM, the Hunter color value in cross section of cooked SPFM was higher in a and $\Delta$E values, while the color was lower in Land b values. Trichloroacetic acid soluble-N content of SPFM was 279 mg/100 g, which was insignificantly different (P>0.05) compared to those of SPM and commercial patty. The hardness of SPFM was 0.44 kg/$cm^2$, which was insignificantly different (P>0.05) compared to that of SPM, while was higher than that of commercial patty. The major fatty acids of SPFM were 16:0 (16.5%), 18:1n-9 (29.2%) and 18:2n-6 (26.1%). The 20:5n-3 and 22:6n-3 were also detected in high composition. The total amino acid content of SPFM was 16.6 g/100 g, which was similar to that of SPM. However, the total amino acid of SPFM was 14% higher than that of commercial patty. From the results of the mineral content, SPFM was higher than that of SPM in Fe and Ca, while the K in SPFM was lower. According to the result of sensory evaluation on the color, flavor and taste, no significant differences in all sensory items between SPFM and SPM were found.

This study investigated the food biochemical characterization of commercial seasoned sea squirt Halocynthia roretzi (CSS). The proximate composition of CSS was 77.2-82.7% moisture, 7.1-9.1% crude protein, 0.3-2.6% crude lipid and 3.5-6.3% ash. Taste compound contents of CSS were 2.3-5.4% salinity (saltiness), 0.42-1.12 g/100 g total acidity (sourness) and 114.9-330.2 mg/100 g amino nitrogen (taste intensity). The Hunter color values of CSS were 23.79-32.50 for lightness, 9.97-20.45 for redness, 14.01-20.96 for yellowness and 64.50-76.63 for color difference. The odor intensity of CSS was 35.0-62.0. According to these results, there were large differences in proximate composition, taste compounds, Hunter color values and odor intensity of CSS. Viable cell counts ranged from 6.20 to 7.69 log (CFU/g), and most of the viable cells comprised of lactic acid-forming bacteria. CSS was not detected in the coliform group.

LCD용 칼라 필터를 제작하는 방법으로 감광성 고분자(photosensitive polymer)에 광 리소그라피(photolithography)기술이 많이 이용되어지고 있다. 이로 인해 감광성 고분자 표 면의 물리적, 화학적 성질이 변하게 되는데, 이는 후속 공정인 플라즈마 식각이나 ITO 전극 의 증착 등에도 많은 영향을 주므로, 각 공정에 따른 이들 고분자의 표면 연구는 매우 중요 하다. 본 논문에서는 blue 칼라 필터의 고분자 표면에 대한 연구를 SIMS와 XPS를 이용하 여 수행하였으며, 표면의 거칠기 변화를 AFM을 통해 관찰하였다. SIMS와 XPS결과로부터 초기 공정인 blue 칼라 필터를 스핀 코팅하고 pre bake한 상태에서는 주로 칼라 필터의 주 성분인 단량체와 결합제의 고분자 물질이 표면에 드러나 있다가, 노광 과정을 거치고 post bake한 시료에서는 색깔을 내는 안료 성분이 표면에 드러남을 확인하였고, AFM을 통해서 는 post bake후에 표면에 더 거칠어 짐을 관찰하였다.
