Dress is an expressive art form which involves a human activity; utilizes techniques under sufficient technical control that results in the production of typical forms on the basis of aesthetic standards. This study was conducted to clarify a relationship of Impressionism and it's image in dress-Bustle style. Artists such as Manet, Renoir, Cezanne, Gogh, Gauguin, and Rodin were reviewed. Impressionism was a method of painting that consists in repoducing an impression exactly as it is experienced from contemplation nature. The Impressionists used a technique of separate, fragmented brush strokes and pure prismatic colore, aiming at rendering changing effects of light. Fashion designers such as Charles Worth, Givency, Cardin, Ungaro, and Lacroix were examined. Throughout their fashions, they focused on the naturalism of feminine and seductive image-the touch of Vegetable Venus depicted on the paintings of Manet and Renoir; expressed "unmitigated sexiness" in various forms of Bustle sytle creating a seductive beauty, revealing body contour, breast and legs, and using a fragmented motif and flowers with vivid color.

The goal of this research is to describe relations between impressions and elements in an image (i.e. color, texture and contours). Adequate image segmentation technique to extract these elements is required. We think that a sketch and a realistic painting are examples of optimal segmented images for our purpose because brush strokes are seem to be segmented areas and realistic paintings should remain the same impression as the model. For the reason, in this paper the segmentation technique which can create realistic painting-like segmentation is exploited. It is shown that the realistic painting-like segmentation is suitable for analyzing images.

본 논문은 첨단 공연 및 전시를 위한 미디어아트 기술에 대한 논문으로 틸트 브러쉬를 사용하여 가상현실 속에서 인터랙티브 스트로크를 생성하도록 한 후 이를 미디어 파사드 기법을 통하여 공연에 실시간으로 투사하였다. 우리의 전통 극 중 봉산탈춤에서 선적인 움직임을 추출하였으며, 틸트 브러쉬로 구현된 선의 움직임을 'Multi-face Convergence'라고 이름을 붙인 미디어아트 공연에 사용하였다. 모션 데이터가 가상공간에 들어오면 면으로 이루어진 지오메트리가 가상현실 공간에 생성되게 된다. 생성된 스트로크는 다양한 브러쉬 타입을 설정할 수 있으며, 공연 시에는 역동적인 움직임에 어울리는 붉은 불의 이펙트가 가미된 스트로크를 사용하였다. 가상현실에서 구현된 인터랙티브 스트로크는 1인 관객을 위한 가상현실 디바이스인 HMD(Head-mounted Display)를 넘어 다수의 관객들이 감상할 수 있도록 하기 위하여 미디어 파사드 기술을 사용하여 공연 공간에 투사하였으며 봉산탈춤을 추는 무용수와 동시에 어우러질 수 있도록 하였다. 가상현실이라는 매체는 폐쇄성이 높은 매체로 공연에 녹아들어 표현하기에는 적절치 않은 특성을 가지고 있지만, 본 공연에서는 미디어 파사드라는 기법으로 그 한계를 넘어섰다. 본 연구는 세계 최초로 인터랙티브 스트로크를 전통춤 퍼포먼스에 결합하여 퍼포머가 표현하는 선의 현상을 미디어 파사드 기술로 공연장에 투사하는 공연 기술 방식을 제안한다.

회화에서 사용되는 효과들을 컴퓨터 화면상에 재현하고자 하는 많은 연구가 있었다. 수채화나 유화와 같은 서양화의 경우는 주로 사진 이미지를 수채화나 유하 효과를 가지는 이미지로 변환하는 기법이 연구되었다. 그러나 동양화의 경우는 서양화와는 달리 사물의 특징을 나타낼 수 있는 몇 개의 스트록(Stroke)만을 사용해서 그려지기 때문에, 변환 기법이 서양화에서처럼 용이하지 않다. 따라서 동양화에서는 주로 그림을 그리는 도구들의 모델링(Modeling)을 통해 결과 이미지를 생성하는 방법이 사용되었다. 본 논문에서는 동양화를 생성할 때, 중요한 요소인 번짐효과를 표현하기 위한 모델을 제안한다. 이것을 위해 스트록의 물 함유 상태를 구분하기 위한 방법으로 계층 모델에 대해 설명하고, 물과 잉크가 종이의 각 셀 사이로 이동하기 위한 모델로 지역 평형 모델을 제안한다. 지역 평형 모델은 빠른 시간안에 효과적으로 잉크와 물의 이동을 계산할 수 있는 한가지 방법을 제공하는 모델이다. 또한 동양화적인 붓의 표현을 위해 붓에서의 잉크 감소 모델에 대해 설명한다. 마지막으로 각 모델들의 모델링 결과로 생성되는 몇가지 효과들과 그려진 동양화 결과를 보여준다.

This study considers the modern expression of oriental esthetics by analyzing the fashion design with the Chinese ink technique based on the concept of Chi-Yun-Sheng-Tung, which was regarded as the best rule of art creation in oriental history. This study was performed by conducting a literature review of related books and advanced studies, and then, collection analysis was done with photos derived from fashion websites (seoulfashionweek.org, chinafashionweek.org, vogue.com, firstview. com) from 2010 S/S to 2016 S/S. A total of 317 fashion photos of designs created using the Chinese ink technique by Korean designers at Seoul Fashion Week and Chinese designers at China Fashion Week were analyzed. The contemporary fashions created with the Chinese ink technique were characterized by, first, the bold brush strokes and natural spreading effects of Chinese ink, second, the emphasis of empty space by taking essential elements, and third, the coexistence of deep Chinese ink colors with modern primary colors. The formativeness of the contemporary fashions created with Chinese ink technique based on Chi-Yun-Sheng-Tung were as follows: first, temperance, pursuing spiritual and minimal expression, second, empty space, making design elements interact and pursue harmony, third, changeable rhythm, symbolizing the growth and variation revealing the power of life, and fourth, vitality, represented in the rhythmical movement of the brush. This study was based on the oriental esthetics inherent in Chi-Yun-Sheng-Tung, and it attempted to analyze contemporary fashion design. The aim was to show the possibility of modern applications to traditional values, and it can be a meaningful case in design planning based on culture.

This paper presents Reflectance Transformation Imaging (RTI) as a tool to support the study of paintings and authentication. Manufacturing techniques of the artist are reviewed through the comparison between liberal perspectives and digital imaging techniques. In this study, RTI was applied to focus on the detailed textural information of eight paintings by Korean artist Lee Ji-ho. The RTI result visualizes shallow reliefs of brush strokes and different mediums on the surface technically enhanced through imaging filters, and these morphological textures on the surface act as a key factor in understanding the characteristics of the artist. The surface morphology and art criticism work as qualitative indicators to analyze the change of artistic techniques through time, and the usage of different mediums. The results of this study confirm that the RTI technique can be used as an analysis device in the study of paintings.

The purpose of this' study was to compare surface roughness and morphologic changes after use of various plaque control devices to titanium implant surfaces. The study materials were 6 ITI titanium implants($Bonefit^{(R)}$) and 5 plaque control devices. 6 implants were divided into 6 different groups and instrumented by each plaque control devices as follows. 1) Group I : untreated control 2) Group II : Titanium curette(Titanium $curette^{(R)}$, 3i) 80 vertical/horizontal strokes 3) Group III : Plastic curette($Implacare^{(R)}$, Hu-Friedy) 80 vertical/horizontal strokes 4) Group N : Plastic tip-ultrasonic scaler($Amdent^{(R)}$, Amdent) 160 seconds 5) Group V : Rotating interdental brush($Identobrush^{(R)}$, Identoflex) 160 seconds 6) Group VI : Abrasive rubber cup polisher($Zircate^{(R)}$, Prophy paste, Dentsply) 160 sec-onds. All specimens were prepared for evaluation by surface roughness tester, optical stereomicroscopy(OM) and scanning electron microscopy(SEM). The Ra and Rt mean values of the tested specimens were 1) Group I ($Ra=0.170{\pm}0.007{\mu}m$, $Rt=1.297{\pm}0.016{\mu}m$) 2) Group II ($Ra=0.209{\pm}0.006{\mu}m$, $Rt=1.602{\pm}0.110{\mu}m$) 3) Group III ($Ra=0.179{\pm}0.001{\mu}m$, $Rt=1.429{\pm}0.055{\mu}m$) 4) Group IV ($Ra=0.182{\pm}0.005{\mu}m$, $Rt=1.511{\pm}0.085{\mu}m$) 5) Group V ($Ra=0.301{\pm}0.008{\mu}m$, $Rt=1.882{\pm}0.131{\mu}m$) 6) Group VI ($Ra=0.147{\pm}0.010{\mu}m$, $Rt=1.059{\pm}0.021{\mu}m$) In Ra values, experimental group II, V, VI were statistically significant different when compared with control. OM and SEM observation showed that experimental group III, IV were minimal changes when compared with control and group VI was smoothest among other experimental groups. The results suggested that plastic curette and plastic tip-ultrasonic scaler were predictable devices to titanium implant surface.

This study aims to find methods that prevents aging of buildings paint coating and that limits defects in construction. Defects in painting can occur in four stages: pure paint, during painting, after the paint coating has dried, and after some period of time has passed after coating. Paint may become bad due to precipitation of pigments, formation of membranes, and seeding during manufacturing. Therefore, it is important that the paint is well mixed and kept airtight at a cool, dark place. Indents, paint brush strokes, orange peel, separation of colors, and paint running and spreading during the paint work process can be prevented by using high quality materials and applying a high-level of construction method. After the paint coating has dried, boiling, yellowing, poor drying, poor bonding, and/or glen deficiency may occur. These are influenced by the levels of cleanness of the dried product, drying temperature and hydration. Then, when the coating has been left dried for some period of time, cracking, peeling, scaling, swelling, discoloring, and/or rusting may develop due to the ultraviolet and contaminants in the air. Since these defects occur due to inappropriate construction schedule and/or hot and humid condition, one must use weatherproof materials. Furthermore, poor paint color may be caused by contamination in the sample plate, discoloration, and/or discrepancies in colors which are due to material differences, level of glossiness, degree of dispersion, dual color property of metallic colors, precipitation of pigments, etc. One should achieve reduction in construction cost and effectiveness in paint work by limiting contaminations in the construction site and strictly observing to construction regulations.

기존의 회화적 렌더링은 영상 기울기(image gradient) 정보를 사용해 스트로크의 방향, 크기, 길이 등을 결정하였다. 영상 기울기는 객체의 모양을 표현하는데 있어서 유용한 정보이지만 풍경화에서 표현되는 객체(물, 나무 등)의 현재 움직임이나 흐름을 나타낼 수 없는 한계를 가진다. 실제 화가들의 그림에서, 객체의 실제 움직임에 기반한 브러시 스트로크는 관찰자에게 객체의 움직임을 보다 쉽게 인지할 수 있게 하며, 그림이 그려질 당시의 느낌을 보다 생동감 있게 전달할 수 있는 장점을 가진다. 본 논문에서는 풍경화의 주 대상이 되는 객체들의 움직임 정보를 기반으로 동적인 객체의 움직임을 효과적으로 표현할 수 있는 회화적 스트로크 생성에 관한 연구를 제안한다. 이를 위해 동일한 시점을 가진 순차영상 집합으로부터 표현하고자 하는 장면의 움직임 정보(크기, 방향, 편차)을 추출한다. 그리고 움직임의 크기가 큰 영역은 움직임의 방향에 기반하여 스트로크를 생성하며 움직임의 정보가 작은 영역은 영상 기울기 값을 기반으로 방향을 결정한다. 우리의 알고리즘은 사실적인 움직임의 방향을 표현하는데 유용하며 이는 풍경화영상을 렌더링 하는데 유용하다.
