This paper focuses on presenting modeling considerations and insight into the performance of typical straight, curved, and skewed box-girder bridges in California which form the bulk of the bridge inventory in the state. Three case study bridges are chosen: Meloland Road Overpass, Northwest Connector of Interstate 10/215 Interchange, and Painter Street Overpass, having straight, curved, and skewed superstructures, respectively. The efficacy of nonlinear dynamic analysis is established by comparing the response from analytical models to the recorded strong motion data. Finally insights are provided on the component behavioral characteristics and shift in vulnerability for each of the bridge types considered.

Design of current lead for 21T superconducting magnets is presented. The current lead is composed of a normal metal element, conducting the current from room temperature to intermediate temperature, and an HTS element, conducting the current down to liquid helium temperature. The metal element is disengaged from the HTS element without breaking vacuum after excitation. The optimization of the lead is performed to minimize the thermal heat load when carrying operational current with some margin. In order to confirm the feasibility of our new design, the intermediate joint between a normal metal and HTS element is fabricated and the reliability is tested during engage and disengage performance. The effects of vacuum level and performance cycle on the electrical contact resistance are also investigated.

David Salle, born in Norman, Oklahoma in 1952, is the most important and controversial artist of the new-expressionist painting in the United States. His paintings are featured by unique artistic language, and extremely diverse and very ground-breaking expression, which reflect the American society at that time. Besides, he often uses complex image combination with striking colors and forms to attract and touch viewers. In this paper, based on the American new-expressionism, the painting language of David Salle's works was analysed, in which I found that it can be more intuitively and more profoundly feel the development of new-expressionist painting context and David Salle's particularity, and more clearly realize under what the characteristics of the era David Salle created the unique artistic language. The study on David Salle's unique painting language is of important research value and reference significance for our current artistic creation.

Painting, as an artistic creation with aesthetic characteristics, is inseparable from "shape". "Modeling" is a subjective way of expressing objects, and "black shape" is not only a way of expression, but also a way of composition. "Black shape" is a way of expressing the overall picture of the creator, and "black shape" extracted from the pattern analysis of black and white gray structure is a powerful means to deeply explore the emotions and thoughts of the painter. How to create the expression of subjective intention in the creation of artificial figure painting and to explore the beauty of picture form and the presentation of formal language in multiple dimensions is always sought by painters. Tang Dynasty political stability, economic and cultural development of unprecedented prosperity, "Toujian Diu" as a representative painting of Tang Dynasty, the figure is plump and realistic, colorful but elegant. It not only represents the aesthetic taste of the Tang Dynasty, but also reflects the overall style of the Tang Dynasty's artificial figure painting. The aim of this paper is to explore the value of "black shape" in "Toughen Diagram" and analyze its multi-component form in depth.

강화 보문사 마애관음보살좌상은 일제강점기였던 1928년에 조성된 거대한 규모의 마애불상으로 한국 근대 불교 조각사에서 중요한 위치를 차지하는 기년명 불상임에도 불구하고 그동안 근대 불교 조각에 대한 연구 부진으로 심도 있는 논의가 이루어지지 못하였다. 본고에서는 보문사 마애관음보살좌상이 근대기 불상으로서 갖는 의미를 다양한 측면에서 살펴보기 위해 마애불 주변에 있는 명문을 판독하여 조성 연대와 제작자 및 후원자를 확인하였으며, 바위의 형태와 지형이 불상의 조형성에 어떤 영향을 끼쳤는지 알아보기 위해 제작자와 참배객의 시점(視點)을 비교 분석하였다. 또한 제작자 후손들과의 인터뷰를 통하여 불상 조성 당시의 구체적 정황을 파악해 보았다. 보문사 마애관음보살좌상의 제작에는 금강산 승려 이화응(李華應)이 화주(化主)겸 화사(畫師)를 맡았고, 불상 조성이 시작되는 1928년에는 100여 명이 넘는 시주자가 공동으로 후원하였으며, 1937년 참배공간을 확장할 때는 간송 전형필(澗松 全鎣弼)이 단독 후원하였다. 이 마애불 조성을 계기로 강화 보문사는 양양 낙산사, 남해 보리암과 더불어 우리 나라 3대 관음 도량으로 손꼽히게 되었다. 불상의 제작 기간은 약 3개월이 소요되었으며 초(草)는 화주를 맡았던 이화응이 그리고 조각은 운송학(雲松學) 등 다섯 명의 강화 지역 석수가 참여하였는데, 화승이 그린 초를 바탕으로 조각이 이루어졌기 때문에 마애불 곳곳에서 선묘적 기법이 발견된다. 화사로서 이화응의 면모가 밝혀짐에 따라 석옹철유(石翁喆有)-화응형진(華應亨眞)-일옹혜각(一翁慧覺)으로 이어지는 화맥의 단초를 확인할 수 있게 되었다. 보문사 마애관음보살좌상은 보관을 쓰고 정병을 든 전형적인 관음보살로 방형의 큰 얼굴에 목이 짧고 전체적으로 투박하여 경직된 인상을 준다. 제작자는 높이 10m에 40°가량 기울어져 있는 바위에 마애불을 왜곡 없이 보이기 위해 최대한 동작을 절제하고 대칭성을 강조하여 세부 표현을 생략하였고, 머리와 신체 비례는 1:1에 가깝게 조정하여 시각적 왜곡 문제를 해결하였다. 특히, 본고에서는 보문사 마애관음보살좌상처럼 별도의 불단을 만들지 않는 '불상과 불단의 일체화'된 형식을 근대기 불교 조각의 특징으로 상정하였다. 그 외에 광배에 새겨진 6글자의 범자(梵字)를 그동안 육자대명왕진언(六字大明王眞言)으로 해석했으나, 정법계진언(淨法界眞言)과 사방진언(四方眞言)이 조합된 것임을 새롭게 밝혔다. 아울러 처마 바위에 박혀 있는 3개의 쇠고리는 제작 과정에서 다림추를 달아 초를 그릴 때 기준점으로 활용하였고, 이후에는 고리에 풍탁을 달아 보살상을 장엄하는 용도로 사용한 것을 확인하였다.

The purpose of this study is to comprehend the color and the coloration of Han-bok on the oil-painting of modern Korea. Generally, the modern Korean art is from late 19th to early 1980s' for the lowest year. Through the introduction of oil painting and the painter's work which had been reflected painter's realism at these times, we might know that the phases of the times and we could see a Korean costume and color combination. In this study, Han-bok is divided to upper clothes, lower clothes and the other parts which was distinguished by the color. The color of Han-bok which is watched on the modern art oil-painting is mainly white. The primary color including red, yellow, blue and middle tone colors is in harmony. It means that the five colors of Yin-Yang Wu-hsing were preferred until the modern times. The coloration of Han-bok is classified to a one-colored arrangement, two-colored arrangement and three-colored arrangement. The one-colored arrangement by white and black is a peculiar coloration to the modern times. The two-colored arrangement is a traditional coloration of Han-bok. The color which is high value and chroma is arranged on jacket, Jeogori. A dimension rate that is related with the difference of value and chroma made a visual harmony. In many cases of the two-colored arrangement of neutral colors is not much different in Jeogori and Chima. So Han-bok which is two-colored arrangement of neutral colors is colored in a breast- tie, pigtail ribbon, cuff and waist band for getting visual focus. The represented three-colored arrangement is white Jeogori and navy blue Chima with red breast-tie. It is a perfect visual color combination. The color of Han-bok was inherited a traditional color and the combination of neutral color was balanced. It was a refinable coloration system according to a difference of value and chroma. It means that a color sensation and arrangement of Korean have been developed by our unique climate, nations and the culture which has been formed for a long times.

In the development of linear perspective, Brook Taylor's theory has achieved a special position. With his method described in Linear Perspective(1715) and New Principles of Linear Perspective(1719), the subject of linear perspective became a generalized and abstract theory rather than a practical method for painters. He is known to be the first who used the term 'vanishing point'. Although a similar concept has been used form the early stage of Renaissance linear perspective, he developed a new method of British perspective technique of measure points based on the concept of 'vanishing points'. In the 15th and 16th century linear perspective, pictorial space is considered as independent space detached from the outer world. Albertian method of linear perspective is to construct a pavement on the picture in accordance with the centric point where the centric ray of the visual pyramid strikes the picture plane. Comparison to this traditional method, Taylor established the concent of a vanishing point (and a vanishing line), namely, the point (and the line) where a line (and a plane) through the eye point parallel to the considered line (and the plane) meets the picture plane. In the traditional situation like in Albertian method, the picture plane was assumed to be vertical and the center of the picture usually corresponded with the vanishing point. On the other hand, Taylor emphasized the role of vanishing points, and as a result, his method entered the domain of projective geometry rather than Euclidean geometry. For Taylor's theory was highly abstract and difficult to apply for the practitioners, there appeared many perspective treatises based on his theory in England since 1740s. Joshua Kirby's Dr. Brook Taylor's Method of Perspective Made Easy, Both in Theory and Practice(1754) was one of the most popular treatises among these posterior writings. As a well-known painter of the 18th century English society and perspective professor of the St. Martin's Lane Academy, Kirby tried to bridge the gap between the practice of the artists and the mathematical theory of Taylor. Trying to ease the common readers into Taylor's method, Kirby somehow abbreviated and even omitted several crucial parts of Taylor's ideas, especially concerning to the inverse problems of perspective projection. Taylor's theory and Kirby's handbook reveal us that the development of linear perspective in European society entered a transitional phase in the 18th century. In the European tradition, linear perspective means a representational system to indicated the three-dimensional nature of space and the image of objects on the two-dimensional surface, using the central projection method. However, Taylor and following scholars converted linear perspective as a complete mathematical and abstract theory. Such a development was also due to concern and interest of contemporary artists toward new visions of infinite space and kaleidoscopic phenomena of visual perception.

Objectives: The objective of this study was to evaluate volatile organic compounds (VOCs) and toluene diisocyanates (TDIs) exposure among polyurethane waterproofing workers in the construction industry. Methods: Task-based personal air samplings were carried out at seven construction sites using organic vapor monitor for VOCs (n=88) and glass fiber filters coated with 1-(2-pyridyl)piperazine(1-2PP) for TDIs (n=81). The concentration of VOCs and TDIs were shown for four different work types(mixing paint, primer roller painting, urethane resin spread painting, painter assistant) at five different worksites (rooftop, ground parking lot, piloti, bathroom, and swimming pool). The two TDI sampling methods (filter vs impinger) were evaluated in parallel to compare the concentrations. Results: The geometric mean(GM) concentration of VOCs Exposure Index (EI) was highest for primer roller painting (1.4), followed in order by, urethane resin spread painting (0.85), mixing paint (0.53), and painter assistant (0.35) by work types. The GM of VOCs EI was highest for bathroom (1.4) followed in order by, swimming pool (0.85), piloti (0.89), ground parking lot (0.82) and rooftop (0.57) by worksites. The GM of 2,4-/2,6-TDI concentration was 0.052 ppb and 0.432 ppb each. There was no statistical difference in TDIs concentrations among worksites. The concentration of 2,6-TDI was ten times higher than that of 2,4-TDI. The concentration of 2,6-TDI by impinger method was 5.7 times higher than that by filter method. Conclusions: In this study, we found 38.6% of the VOCs samples exceeded the occupational exposure limits and 19.8% of the 2,6-TDI samples exceeded 1 ppb among polyurethane waterproofing workers. The most important determinants that increase the concentration of VOCs and TDIs was indoor environment and primer painting work.
