Objectives: The handling of carcinogenic, mutagenic or reproductive toxic (CMR) materials in paint-related products used by automobile maintenance companies in Busan was investigated and its characteristics were analyzed. Methods: MSDS for paint-related chemical products used by automobile repair companies in Busan were collected and the manufacturers, product uses, names of chemical substances in each component, CAS numbers, content, and more were listed. Results: As a result of collecting MSDS on 4,800 kinds of products handled in the painting process of automobile repair companies in Busan and comparing them with the latest toxic information database, 60 out of a total of 438 substances were found as CMR materials. Seven carcinogens (1A), including quartz, benzene, formaldehyde, and hexavalent chromium, were present. Two reproductive toxic 1A substances were included: hexavalent chromium in paint pigments and lead. Conclusions: Most of the products (95.5%) were found to contain at least of one CMR component, so it was judged that a study on exposure assessment of CMR substances by automobile maintenance workers is needed in the future.

The purpose of this study is to find out the origin of perpetuity in the fashion design of Soma Delaunay, who was recognized as a unique designer in the 20th century. Her characteristics of fashion design appeared as dynamism in the incline of op-art using geometric pattern designed on the basis of abstract painting, color contrast between strong original colors, and repeated geometric patterns. The modern image can be explained as modernity in modern fashion and is continued in these days. The origins of modernity analyzed as follows. First, Soma Delaunay developed textile design, considering the use of clothing on the basis of scientific idea. Furthermore, she evolved traditional textile design and making process into a practical and rational way through developing new needlework technique. Second, she tried a new style through a straight silhouette in contrast to Art Nouveau style and the test and mixture of different genres. Third, she expressed the simultaneity of Orphism through the parallel structure of various colors. In particular, she used the contrast of strong and clear original colors to express a rhythm of dynamism and give visual interest through color. Finally, Soma Delaunay attempted to approach the public using clothing, furniture, and curtains with the focus on textiles. It may represent her intention to remove a gap between art and life by understanding the public and their life. As examined above, it can be sad that Soma Delaunay's scientific idea with the flow of industrialization, an open attitude not bound by a rule as an artist, an idea of Avant-garde, the comprehension of various colors and the understanding of the public. These factors lie at the bottom of her fashion design.

This study aimed to reveal the concept and background of emergence of black leather jacket that began appearing in full-scale among youth sub-culture from 1950's, and to research its styles and aesthetic features on the basis of that. The researcher has intended to a theoretical frame to recreate black leather jacket which has been developing in youth sub-culture style as a resource of new design in modern fashion trend through this study There are 5 styles of black leather jacket in youth sub-culture after 1950's. Firstly, biker style black leather jacket showed ruined war heroes substituting for military uniform. Secondly, rocker style black leather jacket brought the conversion in definition of masculinity. Thirdly, greaser style black leather jacket showed the beauty of uncleanness expressing resistance and violence with tattered dirty materials and excessive metal ornaments. Fourthly, headbanger style black leather jacket was prominent in various and compound decoration due to combination of rocker and hippie features. fifthly, punk style black leather jacket was influenced greatly by Sex Pistols. There are broadly three ecstatic features oi black leather jacket among youth sub-culture. With regard to displaying terrorism, black leather jacket displayed threatening aspects with black color, formative beauty of inverted triangle, additional decoration, and animal & brutal feelings. Paradoxical trophyism showed Nihilism, disorder, and resistance through black color that symbolize bad luck and unstability, trophyism with bad flavor, tattered material effect, and destructive message painting. Masculine eroticism appeared in accordance with pursuing after pleasure and masculine sexuality through exposure of buttocks and focused penis due to jacket's short length, and fetish of black.

A field study was conducted during the summer time of 2002 to determine compositions of volatile organic compounds (VOCs) emitted from vehicles and to develop source emission profiles that is applied to CMB model to estimate the source contribution of certain area. Source emission profile is widely used for the estimation of source contribution by the chemical mass balance model and have to be developed applicable for the target area of estimation. This study was aimed to develop source emission profile and estimation of source contribution of VOCs after application of the chemical mass balance (CMB) receptor model. After considering the emission inventory and other research results for the VOCs in Seoul, Korea, the sources like vehicle emission (tunnel), gas station (gasoline, diesel), solvent usage (painting operation, dry cleaning, graphic art), and gas fuels were selected for the major VOCs sources. Furthermore, ambient air samples were simultaneously collected from 09:00 to 11:00 for four days at eight different official air quality monitoring sites as receptors in Seoul during summer of 2001. Source samples were collected by canisters, and then about seventy volatile organic compounds were analyzed by gas chromatography with flame ionization detector (GC/FID). Based on both the developed source profiles and the database of the receptors, CMB model was intensively applied to estimate mass contribution of VOCs sources. Examining the source profile from the vehicle, the portion of alkanes of VOCs was highest, and then the portion of aromatics such toluene, m/p-xylene were followed. In case of gas fuel. they have their own components; the content of butane, propane, ethane was higher than any other component according to the fuel usage. The average of the source apportionment on VOCs for 8 sites showed that the major sources were vehicle emission and gas fuels. The vehicle emission source was revealed as having the highest contribution with an average of 49.6%, and followed by solvent with 21.3%, gas fuel with 16.1%, gasoline with 13.1%.

The purpose of this study is to look for an environmental design method based on open narrative structure, and to promote various experiences and interpretations of space through user's engagements. That is to say, the designer does not lead specific events through separate Boning but using the continuous open composition users are provided with margins for their imaginations. Spatial formulation through open narrative structure gives us various thoughts and it plays an important role in making a sequential space. Like an abstract painting, it is a complex story making or arranging a montage of images containing stories that elicit the reader's engagement through diverse interpretations. Like this, open composition exists in an ambiguous state and it is possible to interpret unfinished‘evolving work’within it. Utilizing open narrative structure, this study attempts to apply the idea of sequencing and open composition in the case of designing Arirang Culture Park. Open composition should induce various engagements by users and could be a medium which organically connects nature, culture and people. The spatial strategies of‘ambiguity’ and‘transparency’are like a bundle of complex and heterogeneous factors. Finally, the study focuses on the ‘integration’of the main ideas that compose multilayered space. ‘Voidness’and‘thickening’are also used for spatial strategies in open narrative structure. As alternative plans for undecided programs of the space, the voidness can be a strategic design program with flexibility about changes of futures. Also, thickening can be a strategic design program for functional reinforcement of the space, for the dramatic effects and for the generation of incidental events. Although both voidness and thickening seem paradoxical, we can see they are similar in the way that both focus on various spatial uses and by how they do not function as one-to-one correspondence, but as multiple correspondences. Therefore, open narrative structure is possible to apply in designing space and it can be an alternative design strategy for inducing multiple interpretations of space.

This research centers on studying the function and characteristic of fashion illustration for advertisement and publication which is, among plenty of fashion illustration's functions, the commercial one. Here are some purposes of the research. First, it presents the function of fashion illustration. Second, under the contemporary circumstance of specialization and subdivision. It givers people the better understanding of fashion illustration by providing a variety of its classification bases other than the typical, simple grouping of style drawing and fashion illustration. Third, this research helps fashion illustration establish itself as commercial art by showing how fashion illustration is utilized in the field as a part of the fashion industry. The methods and contents of the research are described that the concept of fashion illustration, characteristic, classification bases and commercial function are presented and than the data of fashion illustration which hale been used as goods since 1990 in the nation are selected in order to analyze the media for the application of fashion illustration. its expression methods, factors and images. By doing so, advertising fashion illustration are much less than those of published fashion illustration and even most cases of advertising fashion illustration are related just to poster advertisement such as magazines, fashion events or public subscription. The published fashion illustration isn't also attracting the public since it focuses on fashion information books, fashion magazines or fashion -clothing books. Another finding is that the expression style of fashion illustration is not various or distinctive. The expression remains in the trends of painting, figurative drawing, sometimes adopts post-modernism which is reflected in popular cartoon and figures exaggerates or simplifies the human body. The image of fashion illustration is simple. casual or feminine in the rough. For the development of commercial fashion illustration, it is required to produce fashion illustrators, not works but goody, with various concepts appealing to the public.

The relationships between costumes and literature are the remarkable characteristics in the history of Japanese costumes. Among them, the literary designs which have literary subject matters seem unique to Japan. In Japan, the history of the literary design traces far back and its examples are abundant in various literatures in the Heian era. It is particularly notable that the literary designs take a relatively large part of Kosode pattern in the pre-modern period, the Edo era, which can be cleary seen in Kosodehinagata-bon, a collection of Kosode pattern of those era, in addition to various sources of extant relics or paintings. These literary designs lie the tradition of the literary lyricism as aesthetic sense in the japanese costume history. The literary lyricism means the lyrical mood evoked by literature. The purpose of this study is to examine how the literary lyricism which has supported those literary designs was formed and developed. The literary designs on costumes related with the relationships between literature and formative art, for example painting. Those typical example, which started in the literature tournament, utaawase, was devised for matching up with the character of the assembly. They continued as a sort of the intellectual amusements. In the pre-modern period, the literary designs developed In relation to not only subject matters but those expression. Moreover, it shows the extremely typical example that a series of Kosodehiinagata-bons, consisted solely of literary designs, was enjoyed as a device of reading materials like poem anthology.

As Confucian ideology dominated all over the society, the androcentric patriarchical society in the last of Chosun Dynasty produced the unequal power relationship between man and woman. It was traditional hostesses(kisaengs) who uniquely had an occupation among the women in this society. In modern society. they are reinterpreted as 'fashion leaders' or 'professional career women with expert knowledge and it caused a lot of the studies of them to be in a progression vigorously. Therefore this paper studied on the influence of the traditional hostesses(kisaengs) -who were educated and permitted in ther social activity formally in a Confuanism-governed society which forbided a woman to participate in a social activity and which did not gave ladies any formal education. The general hostess in the beginning time of the Chosun Dynasty imitated the hair shape of women in the yangban family which formed the highest class in the Chosun Dyansty and it reflected their aspiration for the highest social class. Howerver, coming into the last age of the chosun dynasty, a reverse phenomenon -that women in the yangban family imitated the general hostesses' hairstyle -occured due to the spread of a genre painting ＆ the concubine system. The general hostesses were educated systematically and did social activity and influenced hair shapes as they were independent economically and their influence in the part of hairstyle appeared as great and high EONJIN MEURI and as one-sided EONJIN MEURI. Regarding-as the result of this study on the influence of the traditional hostess's hair shapes on the ladies hair shapes in the last of Chosun Dynasty -that the traditional hostesse of the last age of chosun dynasty played a role as a fashion leader of the ladies at the same age. the general hostesses in Chosun Dynasty should be revaluated... And the study of ladies which were hidden behind the scenes of Confuanism should be made much more.

The fuel is not injected when the driver doesn't push acceleration pedal of a vehicle with engine speed higher than about 1,500rpm above mid vehicle speed range. This is called "fuel-cut function" and almost every modern vehicle is equipped with this function. This is activated on downhill part of a highway most often. Therefore the vehicle-exhausted $CO_2$ can be zero in this downhill part if the driver could recognize this part of highway. We compared the vehicle-exhausted $CO_2$ emission when using fuel-cut function with the $CO_2$ mass when without using this function in this study. We found that the $CO_2$ emission reduced with fuel-cut function and measured the reduction rate of vehicle-exhausted $CO_2$ mass with this test results. The exhausted $CO_2$ mass of a passenger car(2,000cc engine volume) is reduced by 4% with this function used. This $CO_2$ reduction effect can be achieved if the downhill part of a highway is painted with a specific color. And this road painting can be included in the highway road rehabilitation policy.

Due to the development of construction technology, there is a considerable increase in the number of skyscrapers in the world. Accordingly, there are rapid growing requests about maintenance systems such as cleaning, painting, and monitoring the processes of facade in highrise buildings. However, it is extremely dangerous working the walls of high-rise buildings, and crashes from buildings have accounted for large proportion of constructional accidents. An alternative solution must be developed with the commercialization of automatic robot systems. For the last decade, interest in developing robots for cleaning and maintenance in facade of highrise buildings has continuously increased. The use of automatic robot systems can be expected to reduce accidents and decrease labor costs. In this paper, we propose a new kind of cleaning mechanism. We have designed and manufactured various cleaning tools for different types of facades with economic commercialization. The cleaning cycle, size, and intensity will be determined by economic constraints as well. The final goals are to design and manufacture tools and robots that can clean facades efficiently and rapidly even in dangerous places. The cleaning tool systems consist of nozzles, brush rollers, and squeezing devices. Furthermore, these tools and robots perform each process utilizing the systems of built-in guide types and gondola types for building maintenance. The performance of the proposed cleaning tools is evaluated experimentally; however additional study should be necessary for safer and more stable commercialization.
