We have fabricated white organic light emitting diodes. To obtain balanced white emission and improve the efficiency of devices, thin electron blocking layer (TEBL) was inserted between the emitting layers. We showed that the effective injection of electrons through the optimization of TEBL (a - NPD) embodied the balance of spectra and had a possibility of getting white emission. In a device with 0.3 nm a-NPD, it had a maximum power efficiency of 3.80 lm/w at 250 $cd/m^2$, a luminance of 1200 $cd/m^2$ at 100 $mA/cm^2$ , and the CIE coordinates were (0.353, 0.357).

Effects of dietary protein sources and their amino acid compositions on the liver and plasma cholesterol levels in growing Single Comb white Leghorn male chicks were studied. A diet containing isolated soy protein (21% cp) was supplemented with 0.5% DL-methionine and 0.3% L-glycine. and another diet containing casein(21% cp) was supplemented with 1.5% L-arginine HCl, 0.4% DL-methionine. and 1.0% L-glycine. Plasma cholesterol level was markedly lower in groups force-fed the diets containing either soy protein or casein supplemented with amino acids compared to those found in birds fed corresponding diets without amino acids supplementation. The cholesterol lowering effect of the casein diet. when balanced with various supplemental amino acids appeared to be due to arginine instead of methionine or glycine. It is likely that amino acid balance rather than the composition of a specific amino acid is one of the major factors determining the effect of dietary protein sources on the blood cholesterol levels in chicks.

We fabricated white organic light emitting device (WOLED) with the layered fluorescent blue material and phosphorescent green/red dye-doped materials. Addition of the non-doped phosphorescent host material between the fluorescent and phosphorescent light emitting layers provided the result of broadband white spectrum, with improved balance, higher efficiency, and lower power consumption. In our devices, there was no need of exciton-blocking layer between the each emission layer for the further confinement of the diffusion of excitons.

In this paper, we propose the simplified and improved system of One Color Detector to protect color distortion of simple color images in the processed of Auto White Balance (AWB). The proposed One Color Detector is based on Grayworld algorithm which controls color compensation except one color in simple image and widely applies for mobile phone camera because of high efficiency. This system can be suitable for diverse image size, and let user control the threshold in diverse size and environments compared with conventional system. Also the hardware size of the proposed system is reduced by 80% over that of the conventional one.

This study investigates the physicochemical and organoleptic characteristics of Campbell Early white wines made by a traditional method. The pH values of all Campbell Early white wines were ranged from 3.2 to 3.5 during fermentation. The acidity value of the Campbell Early white wine made by the traditional method was 0.2~0.9%. Sucrose and alcohol contents were 6~7 Brix and 13.2~14.4% respectively at the end of fermentation. Campbell Early white wine had high sensory scores for color, aroma, taste, sharpness, after taste, and overall balance. Since Campbell Early grapes are well fermented due to their rich fermentative sugar content, Campbell Early white wines made by adding K1-V1116 yeast were shown to be the most appropriate.

This study was conducted to compare the quality of Korean and imported wine through sensory evaluation and to determined the harmony between wine and foods. The physiochemical characteristics, such as the sugar content, total acidity, pH and color values of Korean and imported wine were also measured. Three white wines made in Korean (WWK), Germany (WWG) and U.S.A (WWU), and three red wines made in Korean (RWK), France (RWF) and Chile (RWC), were used for testing. In the result of sensory evaluation, the white wine made in Germany (WWG) was the most preferred in flavor, taste and overall preference, and the red wine made in France (RWF) was the most preferred in appearance, flavor, taste and overall preference. The overall preference of wine was positively correlated with the total balance in the white wine (r=0.66) and in red wine (r=0.81). In regards to the harmony of wines with foods, the white wine made in Korean (WWK) was suitable for sirloin steak, the WWG for codfish steak and salad and the white wine made in the U.S.A (WWU) for sandwiches. The red wine made in Korean (RWK) was significantly harmonious with salad, the France red wine (RWF) with sirloin steak and in the red wine made in Chile (RWC) with sandwiches. The L and b-values of white wine were the highest in WWG. the L-values of red wine were the highest in RWK, and the a-values of red wine were the highest in RWC and RWF. The WWU was the highest in sugar content among the white wines $10.83^{\circ}$ Brix and the RWC ($8.32^{\circ}$ Brix) was the highest among the red wines. Total acidity was higher in WWU (0.8) and in RWF (0.45) and thy pH values were the highest in WWK (2.82) and RWK (3.35).

The effects of cecectomy on nitrogen utilization and nitrogen excretion were examined in single comb white leghorn (SCWL) cockerels fed a 5% protein diet supplied with urea. The cecectomy tended to increase nitrogen balance and nitrogen utilization and significantly decreased uric acid excretion (p < 0.01). Urea and ammonia excretion tended to be about 60% increased and decreased by cecectomy in SCWL cockerels, respectively, but blood ammonia, urea and uric acid concentrations were not affected. The results are in good agreement with those obtained previously in cecum-ligated chickens. It is concluded that the improvement of nitrogen utilization and decreases in urinary uric acid excretion in cecectomized chickens do not result from the modification of cecal fermentation.

This study presents five selection rules for training algorithms to extract audio sources from noise. The five rules are Dynamics, Roots, Tonal Balance, Tonal-Noisy Balance, and Stereo Width, and the suitability of each rule for sound extraction was determined by spectrogram analysis using various types of sample sources, such as environmental sounds, musical instruments, human voice, as well as white, brown, and pink noise with sine waves. The training area of the algorithm includes both melody and beat, and with these rules, the algorithm is able to analyze which specific audio sources are contained in the given noise and extract them. The results of this study are expected to improve the accuracy of the algorithm in audio source extraction and enable automated sound clip selection, which will provide a new methodology for sound processing and audio source generation using noise.

Color image sensors (CIS) output color images through image sensors and image signal processing. Image sensors that convert light to electrical signal are divided into CMOS image sensor and CCD image sensor according to transferring method of signal charge. In general, a CIS has RGB output signals from tri-stimulus XYZ of the scene through image signal processing. This paper presents an adaptive colorimetric analysis method to obtain chromaticity and luminance using CIS under various environments. An image sensor for the use of colorimeter is characterized based on the CIE standard colorimetric observer. We use the method of least squares to derive a colorimetric characterization matrix between camera RGB output signals and CIE XYZ tristimulus values. We first survey the camera characterization in the standard environment then derive a SGL(shutter-gain-level) function which is relationship between luminance and auto exposure (AE) characteristic of CIS, and read the status of an AWB(auto white balance) function. Then we can apply CIS to measure luminance and chromaticity from camera outputs and AE resister values without any preprocessing. Camera RGB outputs, register values, and camera photoelectric characteristic are used to analyze the colorimetric results for real scenes such as chromaticity and luminance. Experimental results show that the proposed method is valid in the measuring performance. The proposed method can apply to various fields like surveillant systems of the display or security systems.
