Ultimate objective of industrial hygiene is the prevention of health impairment that may result from exposure to chemicals at workplaces. This implies the definition of permissible levels of exposure, that is, levels that according to the present status of knowledge are estimated to cause no adverse health effects during the lifetime of the workers, and the regular assessment of the possible health risk associated with exposure by comparing the current or the integrated exposure with the permissible exposure limits. Workers in solvent thinner-using occupation environment might be highly exposed to VOCs(volatile organic compounds) because solvent thinner has been used extensively such as painting, spraying, degreasing, coating and so on in Korea. The purpose of this study was to recognize, evaluate and propose the alternative control the VOCs from solvent thinner-using workplace.

This paper presents a Bin-Picking method in which robot recognizes the positions and orientations of unoccluded objects at the top of jumbled objects placed in a bin, and picks up the unoccluded objects one by one from the jumble. A method using feasible region, painting, and hierarchical test is introduced for recognizing the unoccluded objects from the jumbled objects. The 3D information is obtained using the bipartite-matching method which finds the least difference of 3D by comparing vertexes of one camera with vertexes of the other camera, then hypothesis and test are done. The working order of unoccluded objects is made based on 3D, position, and orientation information. The robot picks up the unoccluded objects from the jumbled objects according to the working order. This all process continues to the empty bin.

The purpose of this study was 1) to analize the female figures with potbelly in the nude of the 15th-l6th century, 2) to find out the historic event which made these figures appeared, and 3) to clarify the influence these figures on dress. The results were as follows: 1) There was a sudden decrease in population by the Black Death in the Middle of the fourth century, so supplement of labor was urgent demand at that imp. Childbirth was the only way of supplement of manpower. 2) Therefore, the figure of pregnant woman was regarded as the female figure ideal. The artists depicted this figure ideal in nude. 3) This female figure ideal changed the form of dress. Pillow, pad, and special undergarments were used to make potbelly.

Image which appears in fashion illustration on the late twentieth century is not the representative image as an equivalence to the real fashion styles but the virtual image which bears no relation to any reality. The purpose of this study is review the concept of virtuality and analyze in which way virtual image is expressed in fashion illustrations on the background of Jean Baudrillard's simulacre theory. In post-modem paintings the expression methods of image-virtualization were image mixing through photo-image appropriation, image overlapping, and the icons inserted unreasonably, the focus-out effect through scrubbing and the over-painting on the photograph. Image-virtualization in fashion illustration was expressed through image mixing and expression of image uncertainty. Image mixing was made by photo-image appropriation, image overlapping, connection of heterogeneous images and using interface image, and uncertain image was expressed through the expression of visual ambiguity and virtual movement.

In this study, it can be identified that drawing style of cartoon and fashion illustration are mutually linked and interchanged. The common background of drawing style between cartoon and fashion illustration, is as follows; 1. A means of image communication through mass communication 2. Similarities as visual signs 3. The borderless of painting, illustration and cartoon. 4. Usage of common drawing expressions such as deformation, distortion, exaggeration, metaphor, metonymy. Drawing style interchanging between cartoon and fashion illustration, is as follows; 1. Similar to figure and face are contemporary style, similar figure, Anime style and humourous style. 2. Similar to the way of express is focusing on the line, simplification, mixed computer graphics with hand drawing, artistic expression, the way of multimedia.

This paper investigates the correlation between surface roughness and gloss of aluminium sheet painted waterborne paint. One customer criterion of automotive quality is the as-painted appearance of the final products. Especially, the current emphasis on control of surface roughness of sanded aluminium sheet has been prompted by the automotive industry's concern with the as-painted appearance. because the influence of such characteristics on paintability, and painted appearance is important in defining outer panel requirements for automobile. This paper is dedicated primarily to the issue of painted appearance and reviews for improvement of roughness. The conclusions are obtained as follows ; 1) Painted aluminium sheet appearance is strongly affected by surface roughness of base-metal and influenced by sand paper and sanding method. 2) The painted appearance of aluminium sheets was determined and related to surface roughness parameters, combination of sand paper.

This study aims at finding out the characteristics and influences of Libeskind's early drawing works through comparisons of each drawing. The importance of his experimental drawing works is not only their uniqueness but also relationship to creation and development of his architecture. Libeskind's musical and educational background had great impacts on forming his early drawings. A series of drawings including 'Micromegas', 'Chamberworks', and 'Theatrum Mundi' shows variety and experiments about reconstruction of three dimensional architectural fragments, abstractive line drawing and plane oriented painting. Libeskind himself cease to experiment drawing techniques but their characteristics still remain in his sketches, diagram and conceptual drawings. In spite of influences of undergraduate design studios, theoretical background of graduate studies, their experimental features are due to his continuous endeavor to make and develop his drawing skills and contents. As a result, his early drawings act as media and way to communicate and develop his concepts.

Molten Carbonate Fuel cell is a promising new type electric power generation system which can achieve high efficiency, lower matrrial cost and high operating temperature Making internal reforming possible. Although the development of the MCEC is progressing rapidly toward commercialization, two important tchological problems such as dissolution of NiO cathode and not corrosion of metallic separator plate must be resolved. Because MCFC is operated at $650^{\circ}C$ and the electrolyte is very corrosive, corrosion-resistance of separator plated against oxidation abd molten carbonate is required. Al-coating on separator material for corrosion-resistance was carried out by painting, thermal spraying. hot dipping and vacuum vapour deposition. The corrosion of Al-coated STS 316S and 316L in molten carbonate at $700^{\circ}C$was studied. Vacuum vapour deposition and thermal spraing for Al-coating on STS 310S and 316L were the most effective methods for protecting thestainless steel corrosion in molten carbonate.

회화적 렌더링의 궁극적 목적은 입력된 이미지를 가지고 손으로 그린듯한 느낌을 표현하는 것이다. 이러한 회화적 느낌을 표현하기 위한 요소에는 브러시의 위치 방향, 그리고 사이즈 등이 있다. 본 논문에서는 다음 그려질 위치가 정적 격자단위로 정해지는 것이 아닌 동적인 격자를 사용하여 결정되었다. 이때 브러시의 방향을 효과적으로 표현하기 위해 영상의 방향 보간을 하였다. 그리고 입력 영상과 캔버스의 최대 차이점에서 에지와의 거리를 고려하여 동적인 브러시의 사이즈를 표현하였다. 그리고 텍스처를 가진 다양한 브러시를 사용하여 질감을 효과적으로 표현하였다. 위의 과정들을 통하여 전통적인 오일 페인팅(oil painting)의 결과를 얻을 수 있었다.

Whether there exists a sympathetic neural regulation on the aquaporin (AQP) channels in the kidney was examined. Male Sprague-Dawley rats were used. They were renal nerve denervated by stripping the nervous and connective tissues passing along the renal artery and vein, and painting these vessels with 10% phenol solution through a midline abdominal incision. Three days later, the expression of AQP1-4 proteins in the denervated kidneys was determined. The content of norepinephrine was found significantly decreased following the denervation. Accordingly, the expression of AQP2 proteins was markedly decreased. The expression of AQP3 and AQP4 was also slightly but significantly decreased, while that of AQP1 was not. Neither the basal nor the AVP-stimulated accumulation of cAMP was significantly affected in the denervated kidney. It is suggested that the sympathetic nervous system has a tonic stimulatory effect on AQP channels in the kidney.
