2007년 한․미 FTA 협상 체결로 미국산 쇠고기 수입이 재개된 현재 육질과 가격면에서 우수한 수입육이 늘어나고 있는 상황에서 한우의 경쟁력강화를 위해 많은 노력이 이루어지고 있다. 한우개량농가는 송아지 생산량의 빠른 증가와 송아지 폐사율의 감소로 사육기술이 향상되어지고 있으며, 1993년 이후부터 한우 경쟁력강화를 위해 육질개량에 중점을 두고 거세를 통한 장기 비육으로 1등급이상의 출현율이 점차 증가하는 추세를 보이고 있다. 소비자의 식육패턴도 양적인 측면에서 질적인 측면으로 변화하고 있다. 고급육의 생산은 품종(Course 등, 1989), 성별, 연령(Hunsley 등, 1971) 등에 의하여 결정될 수가 있다. 한우 도체형질에 관한 연구는 국내에서도 최근 박과 박(2002)과 노 등(2004)이 연구 보고하였으나 이는 후대검정우와 후대축들의 도체형질에 관한 연구였으며, 일반 한우 사육농가의 도체형질에 관한 연구는 이루어 지지 않고 있다. 환경효과의 경우 대부분의 연구가 출생년도－계절, 출생지역의 효과를 추정하였으며, 도축년도, 도축계절, 도축지역에 관한 연구는 이루어 지지 않고 있다. 본 연구에서는 일반 한우사육농가에서 출하하여 도축한 축산물등급판정소의 등급판정결과를 이용하여 도축년도, 도축계절, 성, 도축지역이 도체형질에 어떠한 영향을 미치는지 추정하고, 도체형질에 대해 REML(Restricted Maximum Likelihood) 방법으로 유전력 및 유전모수를 추정하여 일반 한우사육농가에서 출하한 개체의 도체형질에 관해 알아봄으로써 후대검정우나 후대축이 아닌 우리나라 전체 도축우에 대한 기초자료를 제공하고자 한다.

This study was conducted to evaluate beef using a color machine vision system. The machine vision system has an advantage to measure larger area than a colorimeter and also could measure other quality factors like distribution of fats. However, the machine vision measurement is affected by system components. To measure the beef color with the machine vision system, the effect of color balancing control was tested and calibration model was developed. Neural network for color calibration which learned reference color patches showed a high correlation with colorimeter in L*a*b* coordinates and had an adaptability at various measurement environments. The trained network showed a very high correlation with the colorimeter when measuring beef color.

We use BV CCD images to investigate the reality of the color gradient within a King type globular cluster NGC 7089. Surface photometry shows that there is a strong radial color gradient in the central region of the cluster in the sense of bluer center with the amplitude of ~0.39 $\pm$ 0.07 mag/$arcsec^2$ in (B - V). In the outer region of the cluster, however, the radial color gradient shows a reverse case, i.e., redder toward the center. (B - V) color profile which was derived from resolved stars in VGC 7089 field also shows a significant color gradient in the central region of the clusters, indicating that lights from the combination of red giant stars and blue horizontal branch stars cause the radial color gradient. Color gradient of the outer region of NGC 7089 may be due to the unresolved background of the cluster. Similar color gradients in the central area of clusters have been previously observed exserved exclusively in highly concentrated systems classified as post core collapse clusters. We caution, however, to confirm the reality of the color gradient from resolved stars, we need more accurate imaging data of the cluster with exceptional seeing condition because the effect of completeness correlates with local density of stars.

Children's museum has roles of the characterized place for children as well as the museum for education. Therefore, specific color selection especially for children is one of the most important points to be considered. This study is the short investigation on various interior color systems of children's museums in Korea. In case of Children's Museum in National Museum of Korea, each exhibition area is apparently divided by adopting colors in accord with the subject of each space. Middle color in that museum generally gives stability, and clear color and accent color give better perception and vitality Children's folk Museum has adopted Korean traditional colors, O-Bang Colors, which have indicated Korean tradition for ages. All sections in Incheon Children's Museum are spatially divided, but similar colors of ceiling, wall, and floor give boring atmosphere. Since original colors of furniture in Science section distract attraction of children, proper color selection should be required for better reaction from children. Therefore, this research is aiming for detailed investigation in color system of children's museum and the proper interior color planning of the next children's museums with their main purpose for children in the future.

This study comparatively analyzed thermal characteristics of the green color, which is currently used the most, and other various colors of a rooftop urethane water proofing sheet. This study also analyzed the cooling performance by color of the water proofing sheet that fused cooling paints, and presented the effective water proofing sheet color for building energy savings. The experimental results are as follows: (1) The value of L (brightness) diminished, and brilliance also became lower from the white color to the black color, and thus, it was confirmed that relatively more heat was absorbed. In a and b chromaticity, which is the color attribute that ignores brightness, no special relationship was identified. (2) Considering that the cooling performance effect is bigger in summer than winter, due to heat reflection, the white water proofing sheet is more effective in building energy savings than the green water proofing sheet that is currently used the most. (3) The water proofing sheet's color has an impact more on cooling performance than the color of the background side of a structure on which water proofing sheet is installed. The experiment object of gray, of which background side is similar to cement mortar, was lower by $5.7^{\circ}C$ than the white background side.

본 논문에서는 컬러 영상에서 관심객체를 분할하기 위해 컬러 분산 에너지를 이용하는 확장 스네이크 알고리즘을 제안한다. 기존 스네이크 알고리즘은 영상 내에 존재하는 다양한 에너지들을 정의하여 영상을 관심 객체와 배경으로 분할한다. 스네이크의 성능은 구성하는 에너지의 특성에 따라 주로 좌우된다. 능동 윤곽선 모델인 일반적인 스네이크 알고리즘은 적용이 쉽고 분석이 용이한 영상의 밝기 정보를 주요 에너지로 사용한다. 그러나 영상밝기의 미분연산이나 에지검출과 관련된 에너지는 잡음에 민감하고 배경이 복잡해지면 성능이 좋지 않은 단점을 가지고 있다. 제안하는 알고리즘은 분할 영역의 컬러 분산을 스네이크의 영상 에너지에 추가함으로써 복잡한 배경에서도 관심객체를 효율적으로 분할한다. 제안하는 확장 스네이크 알고리즘의 성능을 단순한 배경과 복잡한 배경을 갖는 컬러 영상에서 관심객체를 분할하는 다양한 실험을 통해서 입증하였다. 그 결과 정확도 면에서 약 12.42 %의 향상된 성능을 보였다.

In this research, in order to find out the effect of the area ratio in the harmonic sense assessment of the coloration of Korean clothes, the coloration of a Korean jacket and a skirt was compounded with a similar coloration and a contrast coloration. The respondents were asked to evaluate 16 stimuli of the traditional Korean skirt and jacket with the coloration of the Korean jacket/ skirt, the skirt/ Korean jacket was separately compounded to be 4 tones such as vivid, light, dull, dark. The subjects were 44 female undergraduate students. The results of each can be summerized as follows. As to similar coloration, the korean yellow jacket and red skirt, Korean students feel vivid and dull tone was harmonious, and American students feel vivid, light, and dark tone were harmonious coloration. In inversed case, red korean jacket and yellow skirt, both countries' students recognized that the vivid tone was harmonious. Korean students gave higher points to korean traditional dress in similar coloration such as yellow korean jacket which was small area and red skirt which was large area coloration than inversed color area ratio which red korean jacket and yellow skirt. As to contrast coloration, the korean green jacket and red skirt, Korean students feel vivid tone was harmonious, and American students feel vivid, dark tone were harmonious coloration. In inversed case, red korean jacket and green skirt were recognized that any tone was not harmonious for both countries' students. Both countries of student showed the culture gap. Compared with American students, Korean students were familiar with korean dress's traditional coloration, as a result familiar coloration was recognized harmonious coloration.

Recently, the use of color data is growing fast in the area of image processing. To represent full resolution image on a limited output device, image has to be quantized an dithered. So, many dithering techniques are foundd in the printing. In this paper, we propose nonlinear quantization to consider the overlapping phenomena of neighboring printing dots and modified dot diffusion algorithm to compensate the color degradation produced in the quantization process. In the modified dot-diffusion quantization errors to be diffused are adjusted to improve both image blur and color change produced in the dot diffusion. The printed image obtained by the proposed color dithering method has higher visual quality an less color degradation than the images by conventional printing method.

In the area of computer vision, face recognition is being intensively researched. It is generally known that before a face is recognized it must be localized. Skin-color information is an important feature to segment skin-color regions. To extract skin-color regions the skin-color model based on multi-layer perceptron has been proposed. Extracted regions are analyzed to emphasize ellipsoidal regions. The results from this study show good accuracy for our vehicle driver face detection system.
