There are four kinds of diagnosis methods in oriental medicine, and viewing diagnosis(望診) is the most important method among them. There are two ways in viewing diagnosis. These are viewing shape(觀形) and inspecting color(察色). Viewing shape diagnosis includes observation on geometric curve that is made by prominence of bones or lump of flesh, and examination on symmetric disparity and balance of vertical length among three vertical section of face. Inspecting color is literally inspecting several specified region of face. By Viewing shape, we can learn about characteristic physical mechanism of individuals, and basic disposition of reaction from inside and outside infinite stimulations. On the other hand, by inspecting color, we can estimate the very present pathologic and physiologic status of the patient. the estimation is based on principle that inside body changes reveal some reflections on facial skin surface. When you diagnosis patients with inspecting color method, It is important to distinguish color delicately, and to know where to see and what to know from it. The most important and frequently mentioned regions are myong-dang(明堂), eyes(眼) and In-dang(印堂). Myong-dang(明堂) indicates nose. In-dang(印堂) indicates the space between eyebrows. Unlike myong-dang(印堂) and eyes, In-dang(印堂) is occasionally treated as a trivial region then others. But, from research on classical books of facial examination and consideration of it's locational meanings, we've learned In-dang(印堂) is very important in viewing diagnosis, because this region is crossing of the other two regions and this fact means this region expresses the spiritual status as well as physical status in one region.

이미지에 포함되어 있는 텍스트들은 이미지의 내용을 함축적이며 구체적으로 표현하는 정보를 갖고 있다. 본 논문에서는 이러한 정보를 정확히 추출하기 위해서 색 변화 특징을 이용한 텍스트 영역 추출 방법을 제안한다. 관찰에 의하면 이미지 내의 텍스트들은 주변 배경과의 색 변화가 존재하며, 이러한 색 변화를 3차원 RGB공간에서 표현한다면, 명도이미지에서의 밝기 변화에서 표현하기 어려운 영역들을 강조시킬 수 있으며, 조명 변화에도 민감하지 않은 결과를 만들어 낼 수 있다. 색 변화 정도는 3차원 RBG 공간에서의 색 분산(Variance)으로 측정한다 처리 과정으로서 우선 수평 및 수직 방향의 분산 이미지를 구하는데, 텍스트 영역은 두 방향의 분산 값이 모두 높은 특징이 있다. 다음으로 두 결과의 논리적 AND 연산을 수행하여 불필요한 잡영들을 제거한 후 연결요소를 분석, 검증하여 영역을 최종 확정한다. 다양한 종류의 자연이미지로 제안한 방법을 검증한 결과 밝기 변화 또는 색 연속성 특징들을 이용한 방법에서 찾기 어려운 텍스트 영역들을 찾을 수 있는 것을 확인할 수 있었다.

We need to diversify the colors by natural dyeing for promotion and extention of the natural dyes market, because natural dyestuffs have the limitation the number of the colors to express, compare to synthetic dyestuffs. It was investigated that wool and silk fabrics could be dyed to green colors using natural mugwort and indigo as one of color diversification, in order to express green color that is difficult to be shown by natural dyeing. The mugwort dyebath was prepared to concentration of $25{\sim}100g/l$ using dried mugwort plant and indigo dyebath was prepared to concentration of $5{\sim}20g/l$ using natural indigo powder. Wool fabrics and silk fabrics were dyed to green(GY, G, BG in Munsell color wheel) by two batch methods using the mugwort and indigo dyebaths. the mugwort dyeing was applied at $80^{\circ}C$ for 20minutes and indigo dyeing applied for $5{\sim}7$ minutes in room temperature. The colorfastness to drycleaning and abrasion of the dyed fabrics were shown good as grade 4-5 or 5.

Background: The two basic methods that are currently accepted to identify the HER2 status are immunohistochemistry and flyorescence in situ hybridization (FISH). The aim of this study was to perform the dual-color silver in situ hybridization (dc-SISH) technique as an alternative to FISH. Materials and Methods: A total of 40 invasive breast carcinoma cases were assessed for HER2 gene amplification by FISH and dual-color SISH. Results: Significant correlation was found in the HER2 expression results obtained with the two approaches (p=0.001, p<0.05). The concordance rate was 92.3%. Conclusions: Foutine practical use of the dc-SISH method, which is much easier to apply, score, and evaluate, has many advantages. HER2 and CEN17 status can be evaluated simultaneously with the newly developed "Dual-Color Probe". All these specifications and the reliable results obtained support the widespread use of SISH technique in clinical practice.

얼굴 인식 시스템과 표정인식 시스템과 같은 고차원 처리를 수행하는 시스템의 전처리 과정으로써 이미지 영역 내에서 얼굴을 추적하는 것은 중요한 과정이다. 본 논문에서는 피부색과 얼굴의 형태 정보를 단서로 하는 CONDENSATION 알고리즘을 사용하여 얼굴의 위치를 추적하였다. 컬러의 가중치와 형태의 가중치를 결합시키는데 어려움이 있으므로 각각을 단서로 사용하는 두 개의 추적기를 가진 시스템을 제안한다. 제안된 시스템은 복잡한 배경, 피부색의 물체가 이미지 내에 존재하는 경우, 다른 얼굴이 이미지 내에 존재하는 경우 모두에 대해서 훌륭한 성능을 보여 주었다.

현재 많은 칼라 장치는 다양한 방법으로 영상을 재현한다. 그러나 장치마다 재현된 색은 장치 사이의 색역차로 인해 원래의 색과 많은 차이로 보인다. 본 논문에서는 서로 다른 장치에서 동일한 색을 재현할 때 발생하는 색의 오차를 줄이기 위해 영상 의존 색역 사상 방벙을 제안하였다. 이 방법은 색역 사상시 휘도값 변화에 의해 일어나는 휘도값 변화를 보상하면서 채도값을 클리핑한다. 색역 사상시 중심점인 앵커점을 기존의 방법보다 낮게 설정함으로써 원 영상과 재현된 영상 사이에서의 색 오차를 줄였다. 또, 사상된 영상을 색대비를 높이기 위해 프린터 색역을 밝은 영역과 어두운 영역으로 나누어 다른 사상 방법을 사용하였다. 결과적으로 모니터에 나타난 영상의 색과 비슷하고 대비가 높은 영상을 프린터로 재현할 수 있었다.

Six types of ozone passive samplers were fabricated with three different filter substrates and two colorants, and tested for their feasibility on atmospheric monitoring. These passive samplers are based on a colorant which fades (indigo carmine and ChromAir (K&M environmental Inc.)) or produces color (mixture of 3-methyl-2-benzothiazolinone acetone azine and 2-phenylphenol colorant) upon reaction with ozone, whose concentration can be determined by reflectance measurement of the color change. Three filters, namely Whatman No.1 paper, SG81 chromatography paper and Silica Gel coated on polyester (TLC Plates), were prepared and coated with two colorants. The response of these passive samplers in ozone chamber were tested and compared with ChromAir (K&M environmental Inc.) passive sampler. The response of Silica Gel filter impregnated with indigo carmine was the best at the constant concentration exposure.

This paper presents a composite camera calibration method to determine thermal degradation of power distribution equipment by combining an infrared (IR) camera and a color camera. A calibration jig was first constructed to match the properties of the two cameras. Our calibration and visualization techniques allow for the display of two images, one from the color camera and the other from the IR camera with different field of views (FOVs), on the screen at the same time. To confirm its validity, several case studies have been developed to analyze thermal deterioration limits of indoor and outdoor power distribution facilities.

This study reflected sensitivity cognition in using color and evaluated the performance in task regarded GUI environment. Largely, three experiments were conducted. First, the searching time in text environment was compared with the searching time in color environment. Second, to know relationship of hue, saturation, lightness which are factors of color, and searching time, the searching time was measured using two-way ANOVA with interaction with three independent variables: hue, saturation, and distance. Third, sensitivity cognition about color was investigated and the performance of searching task was analyzed in the environment designed by color regarded sensitivity cognition. According to statistical results, the average searching time was decreased about 50.31% in color environment. The searching time was significant among the difference of hue and saturation. For the factor of color, the more the ratio of green and red was increased, the more searching time was decreased. The more the ratio of gray was increased, the more searching time was increased. And the searching time was developed in the environment designed by color regarded sensitivity. The purpose of this study is the presentation of sensitivity realization method and verification in the reflection and application of sensitivity to the industrial environment and design.

Proofing is one of the inspection operations of printing and can be considered a process control step. The three main kinds of proofs are press proofs, photomechanical proofs, and digital proofs. Photomechanical and digital proofs are also generally refered to as "off-press" proofs. Off-press color proofs are more economical than press proofs. Digital proofs offer fast production time along with a much lower cost per page. Hard-copy digital proofs can be output using thermal transfer printers, ink jet printers, and color laser copiers, as well as dye sublimation and electrophotographic technology. Ink jet method is commonly using because of the reasonal price. But ink jet system is difficult to reproduce an exact color proof. This research was carried out for the purpose of optimization of ink jet color proofing, using two kinds of ink jet printers with 6 colors (C, M, Y, K, mC, mM) and 4 colors (C, M, Y, K) system.
