By studying 3-D virtual human modeling, motion-capturing and clothing simulation for easier and safer work clothes development, this research aimed (1) to categorize heavy manufacturing work motions; (2) to generate a 3-D virtual male model and establish painting work motions within a 3-D virtual clothing simulation system through computerized body scanning and motion-capturing; and finally (3) to suggest simulated clothing images of painting work clothes developed based on virtual male avatar body measurements by implementing the work motions defined in the 3-D virtual clothing simulation system. For this, a male subject's body was 3-D scanned and also directly measured. The procedures to edit a 3-D virtual model required the total body shape to be 3-D scanned into a digital format, which was revised using 3-D Studio MAX and Maya rendering tools. In addition, heavy industry workers' work motions were observed and recorded by video camera at manufacturing sites and analyzed to categorize the painting work motions. This analysis resulted in 4 categories of motions: standing, bending, kneeling and walking. Besides, each work motion category was divided into more detailed motions according to sub-work posture factors: arm angle, arm direction, elbow bending angle, waist bending angle, waist bending direction and knee bending angle. Finally, the implementation of the painting work motions within the 3-D clothing simulation system presented the virtual painting work clothes images simulated in a dynamic mode.

The intention of the research is to look into the form reflecting the spiritual image due to Oriental aesthetic from a realistic point of view. In this regard, I will pay attention to examining the process from figurative perspectives, in which painting image by subject acquires the beauty of form. Of the main subjection this paper, figure is an image itself appearing in painting. At this point, I will attempt to show how the meaning and value of image have been interpreted and judged on the aesthetic standard in Oriental painting in particular. For this process, I generalize the conception of the image as 'figure' and through this I will reconsider the standard of understanding and the value of perception regarding painting images on the method which are more applicable to the expressions of Oriental painting. The reason why I try to find out the true nature of images in Oriental painting from a figurative viewpoint is to convert a conventional sense of value which recognizes the images of Oriental painting only as results of idealism, into more practical field. If the true nature of Oriental painting is fixed and restricted to natures of idealism, any productive development and any changes in form for future couldn't be expected at all. In fact, what the ideological and aesthetic values of art suggest is clearly a proof of real art form. However, it is not a hard thing to prospect that only a superficial idealism will be ceaselessly produced, while the practical study about aesthetic values, meaningful results of painting expressions, is totally ignored, if ideology itself is used as criteria to judge the identity of it or if only the idealistic aesthetic values are emphasized while any clue to show a real existence of oriental paintings is not certain. Actually, nobody can deny the fact that interests about real natures regarding art expressions have been relatively ignored while armed with mental ideology for esthetic view of oriental painting in traditionalism Therefore, it is clear that 'spiritual status' itself can generate any form. Traditionally, in the Orient, the standard of judging a real value of things, which put a focus on a spiritual view of value rather than on a materialistic view of it, has been vaguely positioned the identity of images in painting As a result, the aesthetic convention has finally committed to an error that for images of oriental painting, ideological criteria like so called spiritualism are applied as a judging way, and esthetic meanings and values of real painting are considered as strategic results and spiritual intentions.

본 연구에서는 brush painting공법을 이용하여 인쇄형 유기태양전지에 적용이 가능한 ITO nanoparticle/Ag nanowire/ITO nanoparticle (Nano IAI) 다층 하이브리드 투명 전극의 전기적, 광학적, 구조적 특성을 연구하였다. 평균 25 nm 사이즈의 ITO 나노 입자로 구성된 ITO 나노 잉크와 직경 20~25 nm의 Ag nanowire 잉크를 기반으로 Brush painting 기술을 적용해 상온, 상압에서 낮은 면저항과 높은 투과도를 가지는 Nano IAI 하이브리드 투명 전극을 제작하였다. Nano IAI 투명 전극 제작 시 일정한 두께에서 Ag nanowire 코팅을 위한 brush painting 횟수를 변수로 하여 최적화 공정을 진행하였으며, Ag nanowire가 2번 brush painting 된 Nano IAI 다층 하이브리드 투명전극은 $3.4{\times}10^{-3}$ ohm-cm의 비저항과 52.33 ohm/square의 낮은 면저항을 나타내었다. 이를 통해 효과적으로Ag nanowire를 ITO nanoparticle 사이에 삽입할 경우, 고온의 열처리 공정을 통하지 않고 낮은 면저항을 가지는 인쇄형 투명 전극을 구현할 수 있음을 확인할 수 있었다. 특히 Nano IAI 다층 하이브리드 전극은 83.83%의 높은 투과도를 나타내는데 이는 삽입된 Ag Nanowire의 폭과 길이가 나노 사이즈이기 때문에 입사되는 빛이 흡수되기보다 대부분 투과하기 때문으로 사료된다. 또한, XRD 분석과 HRTEM 분석을 통해 Nano IAI 다층 하이브리드 투명전극의 전도 메커니즘을 설명하였다. 이와 같은 우수한 전기적, 광학적 특성은 brush painting 기법으로 제작된 Nano IAI 다층 하이브리드 투명 전극의 인쇄형 유기태양전지 적용 가능성을 나타낸다.

After modernism, artistic movements such as Cubism, Futurism, De stijl and Bauhaus demonstrated a connection to architecture and other plastic arts and developed a tendency towards a synthetic art. Above all, the unification of painting and architecture is the most noticeable point; a blueprint and a multi-coloring space that are applied on 3-dimensions painting brought new dimensions into relief. Following this artistic trend, it is easy to point out that Le Corbusier's works; which were created under the name of Charles Edouard Jeanneret, show the pictorial peculiarity in the Space Design. Even if white space that he has designed under the slogan such as standardization and mechanization, the variety and metamorphism that he has tried to express on his work have widely been recognized. Especially, his late architectural works were produced as the figurative arts expressing the ambiguity of painting and hence led a step towards a synthetic art. The study analyses Le Corbusier's 2-dimensional Painting as well as his 3-dimensional Space Design. Furthermore, it aims at embarking on the unification of painting and architecture in terms of Le Corbusier's synthetic design philosophy.

This paper describes a hardware architecture called Edge Painting Machine for real time generation of scan line images for raster scan graphics display. The Edge Painting Machine consists of Scanline Processor which converts polygon data sorted in their depth priority into a set of scan line commands for each scan line, and Edge Painting Tree which converts the scanline commands set into a raster line image. Edge painting tree has been designed using combinational logic circuit. The designed circuit has been simulated to verify the proper functioning. A salient feature of the EPT is that hardware composition is simple, because each processor is constituted by only combinational logic circuit.

The use of robots for painting operations is a powerful alternative as a means for automation and quality improvement. A typical method being used for motion planning of the painting robot is to guide the robot along the desired path : the "lead-through" method. Although this method is simple and has been widely used, it has several drawbacks a) The robot cannot be used during the teaching period, b) A human is exposed to a hostile environment, c) The motions taught are, at best, human's skill level. To deal with the above problems, an integrated robot-trajectory planning scheme is presented. The new scheme takes CAD data describing the shape and geometry of the objects, and outputs an optimal trajectory in the sense of coating thickness and painting time. The purpose of this paper is to investigate theoretical backgrounds for such a scheme including geometric modeling, painting mechanics and robot trajectory planning, and develop algorithms for generating spray gun paths and minimum-time robot trajectories. Future study is to implement these algorithms on an workstation to develop an integrated software system ; ATPS(Automatic Trajectory Planning System) for spray painting robots.

Objectives: This study was conducted to identify the characterization of organics solvent exposure among painting workers in the shipbuilding painting process, especially for their daily variations(within worker variance). Methods: Charcoal passive dosimeters were worn throughout each work shift for 20 days for five painting workers from October 19 to November 26, 2015. A total of 100 samples were collected, analyzed and compared with statutory workplace environmental measurements. Results: The geometric mean(GM) and geometric standard deviation(GSD) of mixed organic solvent(six substances) exposure index(EI) for the 100 samples were 0.42 and 4.42 respectively. The median and range of GSD for within worker EI representing five workers' daily EI variation is 3.72 and 2.63 ~ 5.20, respectively, which is classified as a very large variation(GSD>3). We were able to divide the painting process into two similar exposure groups(SEGs), Touch-up and Spray. Spray painting workers were much more exposed to organic solvent than Touch-up painting workers(GM=0.71 vs. 0.19), but less variably (GSD=3.64 vs. 4.10). xylene is the substance to which the workers were most exposed(GM=16.19 ppm, GSD=4.36), and the exposure characteristics of six substances including xylene is similar to those of EI. Conclusions: The daily variation of organic solvent exposure in the shipbuilding painting process is so high that statutory Assessment of Reliability of Work Environment Monitoring needs to be conducted with statistically sufficient number of samples and evidence.

Korea and Japan have a cultural homogeneity because they were affected by China. However, each country has developed its own original culture due to their own national characteristic and endemism, In traditional clothing, though Korea and Japan share the same origin, they have developed their own form, Hanbok and Kimono, which have completely different looks. The differences in the traditional clothing is the result of the differences in each country's aesthetic sense, which is reflects in the artwork of those days. Ink-and-wash painting was the typical painting form in East Asia, so Korean and Japanese ink-and-wash painting from that period can be used to observe the differences in the aesthetic sense. This study aims to search for commonly shared aesthetic sense in the design process of Hanbok and Kimono by analyzing the styles of a representative Korean painting, "Sehando(Wintry Days)" and a representative Japanese painting, "Pine Trees Screen". H. Wolfflin's methodology influenced not only painting, but also architecture and sculpture. Therefore, this theory can be applied to clothing, which can be considered a type of sculpture. Modernization of traditional clothing has to start by analyzing the aesthetic sense of artisans that have affected the design of traditional clothing. To spread Hanbok globally and differentiate it from Japanese clothing, we have to acknowledge the differences between Korean and Japanese aesthetic sense, and based on this, we have to develop the design of Hanbok.
