The structural aesthetics of architecture are becoming an inspirational source for many fashion designers and have been reborn in structural fashion. This study planned to analyze the method of expression of structural aesthetics expressed in modern structural fashion design and the construction method to maximize such an effect on the basis of the construction characteristic of Santiago Calatrava as the representative architect of the structural aesthetic. According to the study, the structural aesthetics expressed in modern structural fashion design are as follows: 1) The symbolical formative aesthetic expressed by symbolical inference and analyzation; 2) the dynamic beauty of physic expressed by visual emphasis and dynamics; and 3) the asymmetric beauty of symmetry expressed by metastasis toward the boundary between balance and imbalance. In addition, to maximize structural aesthetics, we used repetition and a progressive technique based on rhythm, asymmetry, and incision-based variances, such as balance, polygon flux, and inference, and analyzation-based distortion as the structuring principle. The following expression methods for maximizing structural aesthetics were found: 1) symbolical and structural exaggeration of appearance; 2) detail technique expansion and material property diversification; and 3) the three-dimensional transformation of structure and shell expression. Structural fashion design was found to have maximized structural aesthetics by using such expression methods to secure artistic esthetics, destroy existing shapes and patterns, and create unique shapes.

Considering the established research about the characteristics of traditional expression in a contemporary korean architecture, there are two critical problems. the one is that the extent of a case is limited to a public building and a large exhibition building. the other is that the angle of research focus on the viewpoint of specific a level. To settle these problems and supplement a established research, this study is to investigate and analyze the characteristics of popular traditional expression in small commercial buildings. In A viewpoint on the expansion of a case and a various angle, A small commercial buildings is selected as a case. because it is felt that the populace's taste vis-a-vis traditional expression. To investigate and analyze, A main analytic criterion is follows. 1) A expressional method on traditional architectural form 2) A expressional aspect by architectural element 3) A expressional aspect in architectural material 4) A expressional aspect in architectural structure. In consequence we can find out the following results in the process of analysis. 1) In expressional method on traditional architectural form, the traditional expression is represented as the imitation and transformation of a traditional folk house forms, and the embodiment of traditional image 2) In expressional aspect by architectural element, the traditional expression elements is mainly represented at a straw roof and a mud-plastered wall 3) the traditional expression material is mainly straw, timber, small wood boards and mud 4) In expressional aspect in architectural structure, the traditional expression is represented from the viewpoint of decorative expression.

The costumes (including mask) of the first World Master series of The National Changguk Company of Korea, Achim Freyer's 'Mr. Rabbit & Dragon king' is directly designed by Achim Freyer who was in charge of direction and stage design. The new form called Pansori opera is proposed for modernization of Korean traditional opera, it maintained the original form of music yet introduced play form of opera. The costumes and stage also promoted modernistic transformation while maintaining the original Korean form. The overall concept of 'Mr. Rabbit & Dragon king' costumes emphasizes comical effect by abstractness like childlike scribble. It expressed characteristic of characters diversely through exaggeration and expansion while maintaining original form of Hanbok, used surface of costumes as a drawing board, and created flat and geometrically transformed silhouette. The complicated characters was caricatured like everyone is doing mask play by using masks, and it still maintained sophisticated oriental color with modern application of five cardinal colors. It may seems it just mixed our traditional elements like a hint of humor, however, it could be known that it introduced various techniques in it to deliver new subject while maintaining the original form of 'Mr. Rabbit & Dragon king'. From this study, open mind for our tradition and need for diverse attempt could be rediscovered and could also see the possibility to contribute on creating a Nation Brand of traditional performing art.

The effects of silicon and molybdenum on the temperature-dependent properties of high silicon and high molybdenum ductile cast iron were investigated. Microstructure was composed of ferrite, cell boundary complex carbide, carbide precipitated in the grain and graphite. The number and size of carbide decreased with the increase of silicon content and increased with the increase of molybdenum content, however, the size of cell boundary carbide increased above 0.81wt%Mo. The room temperature tensile strength increased with the increase of silicon and molybdenum contents. That did not increase with the latter with more than 0.8wt%. Meanwhile the high temperature tensile strength showed the similar trend to that of room temperature one, that of the specimen with 0.55wt%Mo was the highest. The $A_1$ transformation temperature increased with the silicon and molybdenum contents, and showed similar tendency with the variation of strength. It was discussed due to the solubility limit of Molybdenum in ferrite, of which value was assumed to be in the vicinity of 0.81wt%Mo. The weight after oxidation at 1,173K showed the result caused by the difference in solubility of molybdenum in the matrix. That and the thickness change after oxidation did not show any consistent trend with the silicon and molybdenum contents.

As can be seen in US case with the introduction of ISTEA and CAAA, the expansion of the transportation decision-making role of local government is expected to be quite apparent in Korea, and the increased importance of decision-making in transportation issues requires increased attention to both justification and analysis of transportation initiatives. A GIS-based facility management system in a desktop computing environment has been constructed using MapInfo, ARC/INFO, and Microstation to allow such expanded role of local government's decision-making activities. In this paper, first, authors try to explain the procedures of system design; that is, the digital map production including vectorizing, data conversion, attribute data entry, and application programming development. Then, various management functions which are basically embedded in MapInfo environment, and application functions established by the use of MapBasic language has been explored Finally, the possible benefits of combining geographic information systems with traffic planning scheme has also been described with some discussion.

This paper presents a new possibility of calculating optimal control for large scale which consist of non-linear dynamic sub-systems using two level hierarchical structures method. And the proposed method is based on the idea of block pulse transformation to simplify the algorithm and its calculation. This algorithm used an expansion around the equilibrium point of the system to fix the second and higher order terms. These terms are compensated for iteratively at the second level by providing a prediction for the states and controls which form of a part of the higher order terms. In this new approach the quadratic penalty terms are not used in the cost function. This allows convergence over a longer time horizon and also provides faster convergence. And the method is applied to the problem of optimization of the synchronous machine. Results show that the new approach is superior to conventional numerical method or other previous algorithm.

Mg-Ni nanoparticles were synthesized by a physical vapor condensation method (DC arc-discharge) in a mixture of argon and hydrogen atmosphere, using compressed mixture of micro powders as the raw materials. The crystal phases, morphology, and microstructures of nanoparticles were analyzed by means of X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). It was found that the intermetallic compounds of $Mg_2Ni$ and $Mg_2Ni$ formed with existence of phases of Mg, Ni, and MgO in Mg-Ni nanoparticles. After one cycle of hydrogen absorption/desorption process (activation treatment), Mg-Ni nanoparticles exhibited excellent hydrogen absorption properties. $Mg_2Ni$ phase became the main phase by aphase transformation during the hydrogen treatments. The phenomenon of refinement of grain size in the nanoparticle was also observed after the hydrogen absorption/desorption processes, which was attributed to the effect of volume expansion/shrinkage and subsequent break of nanoparticles. Maximum hydrogen absorption contents are 1.75, 2.21 and 2.77 wt.% at 523, 573 and 623 K, respectively.

The eighteenth century in Great Britain was the period of transformation, Great Britain externally experienced several wars intermittently mid internally transformed into the industrial country in the course of the 18th century. British shipowners were faced with short of seamen mainly due to several wars and expansion of shipping tonnage British shipowners tried to solve the mooing problem by decreasing the number of seamen from 22-23 sailors per ship of 100 tonnage in 1710's to 5 in 1810 and increasing seamen's wage from shillings per common seaman per month in the 17th century to 25 shillings in the middle of the 18th century and equation omitted during the French Revolutionary and Napoleonic Wars. What caused and resulted by specialized shipowners to cope with changeable market situation with flexibility was decrease of the number of seamen per ship and increase of wage.

A CCTV system reduces some number of cameras if we use convex-mirror. In this case, convex-mirror Image distorted, we need transformation to flat images. In the center of mirror images, a transformed image has no distortion, but at near boundary image has plentiful distortion. This distortion is caused by occlusion of angled ray and diffraction. We know that the linear filtering approach cannot separate noise from signal where their Fourier spectra overlap. But using a non-linear discretization method, we shall reduce blurred noise. In this paper, we introduce the backward solution of nonlinear wave equation for reducing blurred noise and biased expansion of equilibrium contour. We propose, after applying the introduced method, and calculate with discretization method. To analysis the experimental result, we investigate to PSNR and get about 4dB better than current method.
