In order to pursue the traces of truth, boundaries set by man for convenience were crossed or Integrated leading to the discovery of new paradigms. Such phenomena including collaboration, convergence, crossover and etc. are expressed in various forms across the society and culture. In particular, development of digital technology is moving away from its previous color based on scientific, statistical and quantitative perspective by using diverse variables. Also, as the borderlines of genres become increasingly more ambiguous, various concepts of color blending developed rapidly. Thus These chaosmos-like color blending have created new contents. This research aims to understand the principle of color blending in Karim Rashid's work, which advocates the world of design in diverse fields from industrial products to architecture. The principle of color blending such as information change, source color and destination color, interaction, and etc. makes it possible to extract the expressed element and method of color blending. Meanwhile, the features of color blending such as integrated space and time, vague form, and narrative genre can be inferred from case analysis.

본 논문에서는 포아송 방정식을 기반으로 하는 영상 합성에 있어서 합성된 영상의 자연성을 향상시키기 위한 효율적인 동영상 혼합 블랜딩 기법을 제안한다. 영상 블랜딩 과정에서는 영상 합성의 목적에 따라 포아송 블랜딩과 알파 브랜딩 등 다양한 방법이 사용되고 있다. 본 논문에서 제안하는 혼합 블랜딩 방식은 포아송 블랜딩과 알파 블랜딩의 장점들을 조합함으로써 합성 영상에서 이음매가 없고 또한 객체의 색상 왜곡이 감소되는 특징을 갖는다. 먼저 소스 영상의 객체를 포아송 블랜딩 방법으로 합성한 후, 블랜딩 된 객체와 원래의 객체의 색차를 비교한다. 그리고 색차값이 임계값 이상인 경우, 소스 영상의 객체에 대해 알파 블랜딩을 수행하고 이를 포아송 블랜딩 된 객체와 가중치를 부여하여 합산한다. 모의실험과 분석을 통해 제안된 방법이 포아송 블랜딩과 알파 블랜딩에 비해 합성 영역의 자연성이 우수할 뿐 아니라 요구되는 계산량도 비교적 적다는 것을 볼 수 있다.

Simulating color appearance of makeup effect is an important issue in computer graphics as well as cosmetic industry. Most of previous works on makeup simulation are simple color blending to mimic the cosmetic effects. Some of previous works employed Kubelka-Munk model to accurately simulate the layering effect of cosmetics. However, the simulation limited on single point, and the rest of area are still computed by simple color blending utilizing the color of the single point simulation. This paper presents an image-based method to compute the color appearance effect of makeup application using per-pixel Kubelka-Munk model. Unlike the previous methods, it is possible to compute per-pixel application thickness as well as optical property of cosmetics. The computed thickness pattern can be used in makeup simulation for a more realistic makeup simulation.

Background: This study aimed to investigate the effect of selecting commercially available blending teas and applying them to bovine teeth on color change over time. Methods: After selecting healthy bovine teeth, using a cutting-disc, 105 specimens with a dimension of 5×5×3 mm were prepared, and 15 specimens were distributed to each group. Black tea was used as a positive control, water was used as a negative control, and blended tea of five types was used as an experimental group. First, pH and buffering capacity were measured with a pH meter, and tooth color was determined using a spectrophotometer before immersion in the blending tea solution and 1, 5, 7, 14, and 21 days after immersion. Thereafter, the shape change of the enamel surface was observed using a scanning electron microscope, and SPSS ver.26 was used to analyze the color change. Results: The average pH of the five blending teas in the experimental group was 3.78, and the pH of group 3 (strawberry rhubarb) was the lowest at 3.22. The pH levels of black tea and water were 5.19 and 7.30, respectively. The buffering capacity was the highest in group 3 at both pH levels of 5.5 and 7.0. The L^*a^*b^* color change according to immersion time was the largest in group 4 (rooibos yellow flower), and the amount of color change was large in black tea and group 4. As a result of observing the enamel surface of bovine teeth, changes in the surface shape were noted in all groups immersed in the experimental solution for 21 days, except for water. Conclusion: There was a significant difference between the experimental groups in terms of color change according to the immersion time, and color and enamel surface changes were observed in black tea and all experimental groups, except for water.

The effects of packaging materials on preserving the functional component of pine bud beverage stored under UV (ultraviolet) light exposure conditions were studied. The order of UV light blocking properties of the selected packages was: opaque can> opaque PET (polyethylene terepthalate) with green lamination=transparent PET with 10% PEN (polyethylene naphthalate) blending> transparent PET, and did not depend on film thickness in specified range. At 20${^{\circ}C}$, the order of preserving degree of original color and endobornyl acetate, which is quality index of pine bud beverage, was the same as above. Exposure to UV light can cause of deterioration of functional food components, but green color lamination and blending of PEN materials with transparent PET help to preserve the UV sensitive pine bud beverage components. However, the treated PET bottles have poorer preservation capabilities than the opaque cans. Transparent PET with PEN blending, in particular, will be very useful packaging material for colorful functional beverage preservation by helping to protect the ingredients while attracting consumer attention.

This study proposes a method of blending visible and near infrared images to enhance edge details and local contrast. The proposed method consists of radiance map generation and color compensation. The radiance map is produced by a Laplacian pyramid and a soft mixing method based on principal component analysis. The color compensation method uses the ratio between the composed radiance map and the luminance channel of a visible image to preserve the visible image chrominance. The proposed method has better edge details compared to a conventional visible and NIR image blending method.

In this paper, PVA(polyvinylalcohol), oxidized starch and SBR latex were used as binders for ink-jet printing papers, and their effects of the type and blending ratio of binders on ink-jet printing properties were compared. In case of coating color using PVA mainly used for a binder in ink-jet printing, spreading of printed letters decreased and excellent images were manifested resulting from strong hydrophilic of PVA. However, increasing solids content of coating color was somewhat limited because of the interaction of PVA and functional groups in silica as well as high molecular weight of PVA. When oxidized starch and SBR latex were mixed with PVA at desirable ratio to solve these problems, runnability in coating process was improved and good printing properties were shown. Gloss was improved when latex was used along with PVA as a binder because of the thermoplastic property of the latex. From this result, possibilities of high solids content and high gloss ink-jet printing papers were investigated.

Steampunk is a term generally used for one of the S. F. subgenre in literature, arts, fashion styles, and lifestyles. This study clarifies formative characteristics as well as the meanings of steampunk fashion style based on its attributes in movies and animations. Attributes of the steampunk are blending time, blending technology, and introspection against science development. In order to have an objective research, this study researched frequency of the fashion item, color, accessory of the collected fashion image, and after interpreted that consequence. Men's steampunk fashion was composed of men's basic outfit such as shirts, vest, jacket, pants, and coats of the 19th century. Black color took up the largest proportion for color. In accessory, top hat, goggle, and steam-powered weapons, in order, were most commonly used. Women's steampunk fashion was composed of shirts and long one-piece dresses, long skirt simply applied 19th victorian style fashion. Yellow, brown, and black color took up the largest proportion of fashion color. In accessory, top hat, belt trimming, corset, and boots, in order, were most commonly used. It is the characteristics of the steampunk fashion that represents retro-future fashion, as it features steam-powered mechanic esthetics, a kind of DIY subculture and transcending division of nationality, class, and gender.

본 논문은 윤곽 형상에 밀착된 임의 형상 마스터를 이용한 스키니 스머지 블렌딩 방법에 관한 것이다. 스머지 툴(smudge tool)은 Adobe Photoshop CS6에 내장된 대중적인 그래픽 툴로서 물감을 화폭 상에 문질러서 흐려지게 할 시에 이용된다. 그 효과는 지두화법과 매우 유사하다. 스머지 툴은 Adobe Photoshop CS6의 툴박스에서 스머지 아이콘을 선택한 다음에 화폭 위를 클릭한 후, 마우스 버튼을 누른 상태에서 번짐 효과를 주고 싶은 방향으로 끌어당김으로써 그 기능을 이용할 수 있다. 그러나 기존의 스머지 툴은 마스터 반경 내의 모든 화소값을 블렌딩시켜 결과 영상을 생성함에 따라 원하지 않는 부위의 화소마저도 변형시키는 단점이 있다. 이러한 단점을 해결하고자 본 논문에서는 임의 형상 마스터를 이용한 스키니 스머지 블렌딩 방법을 제안하고자 한다. 제안된 블렌딩 방법은 컬러 영상 분할에 통해 윤곽 형상에 밀착된 임의 형상 마스터를 추출함에 따라 배경에 관계없이 변형하고 싶은 부분에만 번짐 효과를 적용시킬 수 있는 장점이 있다.
