  • The characterization process for the accurate color reproduction in mobile phone with camera and LCD is popular. The camera and LCD characterization, gamut mapping process is necessary to map the camera's input color stimulus, CIEXYZ value, into the LCD's output color stimulus. Each characterization is the process estimating the relation between input and output signals. In case of LCD, because of output device, the output color stimulus for the arbitrary input signal can be measured by spectro-radiometer However, in the camera, as the input device, the characterization is an inaccurate and needs the manual works in the process obtaining the output signal because the input signal can not be generated. Moreover, after gamut mapping process, the noise is increased because the optimized gamma tone curve of camera for the noise is distorted by the characterization. Thus, this paper proposed the system of obtaining the output signal of camera and the method of gamma correction for the noise. The camera's output signal is obtained by RGB values of patches from captured the color chart image. However, besides the illumination, the error for the location of the chart in the viewfinder is generated when many camera modules are captured the chart. The method of correcting the position to correct the error from manual works. The position of camera is estimated by captured image. This process and moving of camera is accomplished repeatedly, and the optimized position can be obtained. Moreover, the lightness curve of camera output is corrected partly to reduce the noise from the characterization process.

  • Woody breast (WB) is one of muscle myopathy found in chicken breast, characterized with enlarged size and extremely stiff texture. The WB condition is one of the most prevalent quality issues in the modern poultry industry. WB has been shown to be heritable, but no effective detection method of WB severity in live birds exists for the selection purpose. The objective of this study was to determine potential of a non-invasive, portable digital palpation device as WB detection method that can be used for the selection to estimate the heritability of WB. The physical and functional properties of WB was also investigated in comparison with normal breast (NB). Two hundred ten breast muscles were obtained from a local processing plant one day after harvest and sorted based on WB scoring (1 for NB and 2 and 3 for WB). The samples were subjected to physical and physicochemical analyses, determining biomechanical properties (muscle tone, stiffness, elasticity, relaxation, and creep), pH, color, cooking yield, and texture (firmness and compression energy were used for raw meat and shear force and energy for cooked meat). The least squares means of the following variables were significantly different between WB and NB (p < 0.01): stiffness (603.4 vs 565.8; N/m), and elasticity (1.40 vs 1.55). However, relaxation and creep were not significantly different (p > 0.05). These results collectively showed that biomechanical properties of WB differ from NB. The degree of muscle stiffness in WB can be considered as a trait to be selected. The WB score showed strong negative correlations with cooking yield (-0.77) and cooked L*(-0.74), which means that as the breast becomes harder, the cooking yield decreases, and the color becomes darker after cooking. The WB score showed high correlations with physical and functional characteristics and exhibited strong correlations with the biomechanical properties measured by the device. Therefore, the results indicated that the digital palpation device has potential to detect the WB severity (degree of stiffness) of breast muscle.

  • This study is done to assist in the limit of stage dress design research considering the sense of the times and the sympathy of spectators for actual stage. For the base research, to visualize the image which the spectators are feeling from Shakespeare's Hamlet, the evaluators had to analyze the whole image and color tone of the figures. First of all, 2 clothing for Hamlet, Gertrude and Ophelia had to be designed, and following conclusion has drawn. Hamlet A corresponds with passive looks which is a combination of loneliness, sadness and the unstable mental state of not adapting to and hiding from the reality. Hamlet B has more of matured looks which make Hamlet more free and comfortable from life and death as he overcame a crisis of death. Gertrude A corresponds with the image of coming right out of the funeral of late king. Gertrude B shows more of her sadness as she hears of her son Hamlet's despair and resentment and her maternal return degradation which is a special situations emphasizing her unstable and dizzy image. Ophelia A shows her usual and normal looks of a livelihood and femininity. She congratulates the wedding and coronation, and falls in love with Hamlet which shows a lot of her girlish image. Ophelia B shows dismantled rationality and violated virginity which is a very complex and unstable state showing a completely different image. Based on the above research. It was proposed their clothing through the next study of the characters, and personally make them for 2003 Yeonheedan Street Group's performance Hamlet.

  • This study measured temperatures and albedos of urban surfaces for different colors and materials during summer, and calculated the energy budget over different urban surfaces to find out the thermal performance affecting the heat built-up. The study selected six surface colors and 13 materials common in urban landscape. Their surface temperatures (Ts) and albedos were measured at a given time interval in the daytime from June to August. Average Ts over summer season for asphalt-colored brick was $4.0^{\circ}C$ higher than that for light red-colored one and $9.7^{\circ}C$ higher than that for white-colored one. The Ts for artificial surface materials of asphalt paving, brown brick wall, and green concrete wall was $6.0^{\circ}C$ higher than that for natural and semi-natural ones of grass, grassy block, and planted concrete wall. There was the greatest difference of $16.3^{\circ}C$ at midafternoon in the Ts between asphalt paving and planted concrete wall. Average albedo over summer season of surface materials ranged from 0.08 for asphalt paving to 0.67 for white concrete wall. This difference in the albedo was associated with a maximum of $15.7^{\circ}C$ difference at midafternoon in the Ts. Increasing the albedo by 0.1 (from 0.22 to 0.32) reduced the Ts by about $1.3^{\circ}C$. Average storage heat at midday by natural and semi-natural surfaces of grass and grassy block was about 10% lower than that by artificial ones of asphalt, light-red brick, and concrete. Reflected radiation, which ultimately contributes to heating the urban atmosphere, was 3.7 times greater for light-red brick and concrete surfaces than for asphalt surface. Thus, surfaces with in-between tone and color are more effective than dark- or white-colored ones, and natural or semi-natural surfaces are much greater than artificial ones in improving the urban thermal environment. This study provides new information on correlation between Ts and air temperature, relationship between albedo and Ts, and the energy budget.

  • The purpose of this research is to find out the effect of a chromatic Korean jacket and an achromatic Korean skirt on the visual image of a traditional Korean dress wearer. This experiment was designed to the 3 factors which were composed of 3 colors(red, yellow, green), 4 jacket tones(vivid, light, dull, dark), and 4 skirt colors(N9, N7, N4, N2). The 288 students in Gyeongsang National University assessed the 48 stimuli which wear variously incorporated with colors and tones by a semantic differential scale of 7-point: The results of the study were as follows. Image factors of stimuli are youth and activity, gracefulness, visibility, and tenderness. Among these, youth and activity factors, and gracefulness factors proved to be important. The colors and tones of a jacket and a skirt used in this experiment showed that the colors and tone had an effect on dimension of 4 images by interacting of two valuables or working independently. While a yellow jacket with vivid and a white(N9) skirt had a significant effect on youth and activity factors, a red jacket and a dark- gray(N4), -black(N2) skirt were evaluated as a graceful image. In the red jacket case, a visible factor was considerably different according to skirt tones. Only jacket tones worked as a striking clue in a tenderness factor.
