19세기 화사(畵師) 원담내원(圓潭乃圓)과 해운익찬(海雲益贊)의 밀교(密敎)이해에 대한 연구(硏究)

다양한 밀교적 도상과 색채를 통해 한국의 金剛界 37尊 만다라 전개의 결정체라 할 「大芚寺 法身中圍會 37尊幀」을 그린 圓譚乃圓과 海 雲益贊 두 佛母의 佛書 양식을 살펴보는 것은 韓國의 金剛界 37尊 도상의 특징을 규명하는 중요한 요소이다. 또한 행장을 통해서 알 수 있듯이 이들은 단순히 기능적 역할만 한 것이 아니라 일반미술에 대한 기량과 밀교에 대한 이해를 전제로 하고 있다. 원담내원과 해운익찬 佛畵의 특징은 차분하고 절제된 분위기의 필선과 그러한 필선에 적절하게 잘 어울리는 채색법이나, 의습 표현이 힘차고 과감하게 나타난다는 점이다. 또한 수묵 禪書에서나 가능할 것 같은 대범한 기법이 채색으로 그려지는 본격 佛畵에 사용되고 있는 점은 중요한 특징이라고 하겠으며 필선의 장점을 살린 홍탱화도 주목된다. 그리고 이들 佛書에 전반적으로 나타나는 특징은 瑞雲의 표현과 관련된 하늘의 표현이다. 주색과 녹청색을 주조색으로 하여 변화 풍부하게 그려 주고 하늘은 거의 검정에 가까운 짙은 청색으로 처리하여 다양한 색감을 통일시키면서 화면에 안정감을 주고 있다. 이와 같이 원담내원과 해운익찬 佛書의 실험성과 독자성은 당시 淸나라로부터 유입하는 洋靑의 적절한 사용과 함께 일반미술에 이해와 외래사조의 수용에도 선구적이었기에 「大芚寺 法身中圍會 37尊幀」과 같은 한국형 금강계만다라가 그려 질 수 있었다고 하겠다. “37 Sacred Images Tanga Painting of the Daedun Temple” is a master piece of 37 sacred images of the Vajradhatu Mandala drawn through various esoteric Buddhist paintings and colors. This study analyzes the styles of Buddhist paintings of Naiwon and Ikchan, the two painters who drew these pictures. Based on this, this study consists of the contents that would investigate the characteristics of 37 sacred images of the Vajradhatu Mandala of South Korea. In addition, the following can be found through the two painters’ lives. This study noted that they did not simply play a functional role, but they also presuppose the ability of general art and the understanding of the Esoteric Buddhism in these pictures. The characteristic of Naiwon and Ikchan Buddhist paintings is their drawing lines in a calm and restrained atmosphere, which suit appropriately with the paintings. Also, the coloring method appears forcibly and resolutely as compared to other Buddhist paintings. For example, the fact that the bold technique, which might be possible in the black and white drawings of Zen, is used for the first time in Buddhist paintings drawn in the form of color paintings, which is an important characteristic. In addition, attention is paid to the red tanga paintings, too, which utilized the strengths of the drawing lines. The overall characteristic of these Buddhist paintings is the expression of the sky related to the expression of auspicious clouds. They drew changes richly, using the red and green colors as core colors, while they used the dark blue color, almost like the black color in the sky to unite various colors and give stability to the pictures. Like this, the experimental nature and unique characteristic of Naiwon and Ikchan Buddhist paintings used the dark blue color (Indigo) imported from the Qing dynasty. This means that they pioneered in accepting foreign trends on the base of a sufficient understanding of traditional general art. Thus, it was the background in which Korean-style 37-Honoured Ones within the Diamond World Mandala like “37 Sacred Images Tanga Painting of the Daedun Temple” could be drawn.

The speed-up of conventional trains is considered as one of the efficient methods to relieve traffic jam and to increase the capacity of transportation. In this study, we measured and analyzed the ride comfort of a push-pull Saemaeul Train with speed-up of 5㎞/h in curves and 10㎞/h on straight tracks as compared with present operation speed of the push-pull Saemaeul Trains. Four main lines-Honam, Kyungboo, Janghang, Kyungjeon- were chosen as representative lines for speed-up feasibility study. The increase of mean ride comfort index in case of speed-up is 0.5~2㏈. The mean ride comfort index of vertical direction in case of speed-up is 107~110 ㏈ for Honam line, 104~112 ㏈ for Kyungboo line, 108~112 ㏈ for Janghang line and 105~108 ㏈ for Kyungjeon line, which are rather high as compared with German trains of similar grade with maximum vehicle speed of 160 ㎞/h.

we studied the structural weak areas of an electric car bogie frame by finite element analysis. The bogie frame under consideration is a part of the standard electric car with aluminium car body. Vertical, torsional, lateral and longitudinal loadings were applied. Numerical results were compared with the experimental results. The two results are in a good agreement.

In this paper, we conducted finite element analysis to investigate the residual stress redistributions of<br/> weldment due to cutting. To evaluate the effect of the residual stress on the fatigue behavior of weldment, test<br/> specimens are commonly cut from the weldment, but the distributions of the residual stress in the cut<br/> specimen should be different from those in the original weldment. Our work is to evaluate the difference<br/> between the residual stresses before and after weldment-cutting to understand the effect of cutting on the<br/> residual stress. Transient heat analysis, elastic-plastic mechanical analysis and element removal technique are<br/> used to simulate the welding and cutting procedures on the commercial finite element code ABAQUS.
