Purpose: This paper is an attempt to explicate the principle of space and form-making in Le Corbusier's architecture from the viewpoint of integrating and relating architecture with the natural landscape. It shows thereby how the geometrical element of architecture and the non-geometrical element of the nature coexist in terms of form. It also explains how space is deployed for the construction of cognitive system between natural landscape and architectural scenery in terms of space, hoping to make a contribution to design method of contemporary house as an elementary datum. Method: Three issues are studied, focusing on the designs around nineteenth thirties in the earliest phase of Le Corbusier: How architectural form and nature is related, how natural greens is introduced into urbanism, and how natural landscape is introduced to house design. 1) it is studied how the relation between the nature and the formal elements of purism in Le Corbusier's architecture is formed. 2) it is studied how the relation between the nature and architecture proposed in Le Corbusier's urbanism is formed. 3) Le Corbusier's "four compositions" is analyzed in terms of relation-formation between architectural space and the nature. 4) it is studied how the natural landscape is introduced to Le Corbusier's house-design in the form of architectural promenade. Result: It has been found out that the natural landscape in Le Corbusier's architecture is not just a simple background, but a necessary element for the consummation of form and space in his architecture, and that architectural inspiration is maximized with coexistence with nature.

This paper discusses the hull form generation from fuzzy model constructed with actual ship data using fuzzy concept. SAC, which is the most important factor in the hull form generation, is expressed by a fuzzy model describing the relationships among design parameters, which have a great influence on SAC, through model identification process with the actual ship data and design parameters. Then, we can infer the SAC of an aimed ship through the process of fuzzy inference and decide the offset of a front view by making the fuzzy model between SAC and offset as well. In conclusion, this paper makes a step forward from the geometrical definition, which has been used for hull form generation so far, to direct mathematical formulae about the relationship between design parameters and offset. So, if the design parameters are given, we can generate the hull form taking such properties into account.

The design of geometrically invariant watermarking is one of the most challenging work in digital image watermarking research area. To achieve the robustness to geometrical attacks, the inherent characteristic of an image is usually used. In this paper, a geometrically invariant image watermarking scheme using connected objects and gravity center is proposed. First, the gray-scale image is converted into the binary one, and the connected objects according to the connectedness of binary image are obtained, then the coordinates of these connected objects are mapped to the gray-scale image, and the gravity centers of those bigger objects are chosen as the feature points for watermark embedding. After that, the line between each gravity center and the center of the whole image is rotated an angle to form a sector, and finally the same version of watermark is embedded into these sectors. Because the image connectedness is topologically invariant to geometrical attacks such as scaling and rotation, and the gravity center of the connected object as feature points is very stable, the watermark synchronization is realized successfully under the geometrical distortion. The proposed scheme can extract the watermark information without using the original image or template. The simulation results show the proposed scheme has a good invisibility for watermarking application, and stronger robustness than previous feature-based watermarking schemes against geometrical attacks such as rotation, scaling and cropping, and can also resist common image processing operations including JPEG compression, adding noise, median filtering, and histogram equalization, etc.

The aim of this research is to analyze Vionnet´s geometric features, which can be regarded as the key formative beauty among the external characteristics of her works. and to thereby establish the theory that her works emitted a time-transcending life force because they were patterns designed based on a geometrical frame of mind. To prove such argument, studies to understand the basic geometrical aspects appearing in her works will be made by taking a look at the general features of geometry, viewing Vionnet´s philosophy for designing, and examining the geometric cutting methods. The period covered in this paper will center mainly on dresses Vionnet made from her very active days in the fashion sector, 1919. till when she retired from the fashion industry, around 1939. What's outstanding about Vionnet´s geometric principle expressed in her works is the unique cutting method that acknowledges the silhouette of the human body as a cubic or three-dimensions concept, through insight of the human body, the mechanics of the materials, and geometry. Vionnet introduced a simple and elegant design by combining geometric figure cuts, such as rectan히es. quadrants, and triangles. Moreover, she created a new sewing structure that plans everything about the materials to the tiniest detail, resulting in producing a softer style With this, Vionnet showed the geometrical correlation can bring about harmony and the beauty of ideal proportion, forming the source of eternal beauty. As discussed so fu, the geometrical characteristics appearing in Vionnet´s works are marked such as spirals, zig-zag lines, asymmetries. panels, gradation, golden proportion, and the mobius-band.

In the early 20'c, scientific thoughts make a change the absolute and separate concept of space-time into relative concept of continual entity; a kind of ideal world. It suggests that the meaning of geometry as absolute truth with which has endowed human beings would changed to a relative meaning of accumulation in intellectual work on 'nature'. This cognitive changes appeared into absolute arts in 20'c like Cubism, Superematism or Constructivism. De Stijl movement which had recepted the relative concepts like Einstein's 'theory of relativity' as a developed thought from Newton-Cartesian cognition on the world. Abstration would be adequate method for expressing the dynamics and interrelationship between forms and for giving values to indivisual elements in a compositiov. This method had appeared Modern architectural form, as a common framework. The expression characteristics of geometrical design in Deconstructive and Experimental architecture were summerized in four features through the results of the analysis. First, the relation of architectural element and intertextuality is expressed in discontinuation of context and refusal of functional building. Second, the concept of trace expresses as connection of place, decomposing of excavation of trace, trace of axis, trace of fragments. Third, anti-gravity expression is there to express of open cubic, to outgrow of rectangular system, to outgrow of volume, to separate of ground connectiov. Fourth, the complex composition of abstracted geometric form is these to abstracted geometry about indefinite shape, to layer through the overlap and collage, to de-meaning and amusement of form through the pursuit of uncertainty, to indeterminate of formal meaning through operation and composition of similar form cause to the diverse of meaning.

This research examined the design characteristics of Madeleine Vionnet, a female fashion designer who left an enormous legacy and made a great contribution to the high added-value fashion industry. Her techniques can be dividing in to three types: the bias cutting, the design by geometrical methods, and the classical style of ancient Greek clothing. This research also intended to study the design cases in which Vionnet's drapery images are applied to modern fashion, mainly the haute couture works that have appeared at Dior collections since 2000. In terms of the characteristics of Madeleine Vionnet's design, First, she produced the best achievement in dress and ornament history by developing a new technique called bias cutting. Second, her work was groundbreaking because it changed the previously planar approach to the female body into a solid conception by cutting and connecting geometrical pieces in the form of quadrangle, triangle, and a quarter-circle. As a result, her works depicted feminine beauty to the fullest extent through the combination of the human body, excellent materials, and the most sophisticated technology and personal skill. Third, her approach was a classical style tinged with the Greek costume image. With this style, which was born by reinterpreting the key tone of the Greek epoch in a modern way, and transcending and even changing tradition, she created a form of beauty that only she could.

The purpose of this study is to analyze the hydraulic characteristics of the ice-harbor fishway by considering its geometrical form and utilize such analysis results as the foundational database to be used when establishing fishways in the future. first of all, the study realizes the same form as an ice-harbor fishway that is currently implemented via a FLOW-3D model and estimated the parameters that were optimal to the numerical mock test. Then, this study analyzed the level of sensitivity of the flow conditions which fluctuated due to the changes in geometrical changes by adjusting the inclination and pocket spacing by using the estimated optimal parameters. As a result, the study arrived at the following conclusions. The vortical velocity increased and had a significant effect on the inclination of the fishway. Furthermore, as the velocity within the vorticity increased due to the narrowed vortical area, it was determined that further studies on vorticities or the determination of the design method for the decrease in vortical velocity were imperative.

This study analyzed expression types of dot patterns and derived out inherent characteristics to provide fundamental resources for advancement of high value added creative designs. As a result of the study, Firstly, the circular motive was used to form silhouettes or as a symbol of a decoration. Secondly, a simple form and color dot pattern was used to create one side, or a circular shaped accessory was used to be recognized as a construction line or a decoration line. Thirdly, textile printing is mainly used but handicraft and decorative images were used to add vitality through piece technique, embroidery, collage, cut-out, patch work, etc. Fourthly, different circular motives were integrated, partitioned and duplicated for abstract geometrical images. Fifthly, variations were added by mixing different dot patterns that are arranged regularly and irregularly in different sizes and gaps creating compounded designs with handicraft touches, different angles or on top of each other. Sixthly, hybrid images were created with rearrangement of dot patterns and by adding floral shapes, stripes or other abstract and geometrical shapes. Such various and creative attempts construct new formative beauty in fashion design and I believe that it can establish the development of unique images that satisfies the taste of today's consumers.

This study selects camellia flowers as a material for design development and created patterns by simplifying the image of camellia flowers and combining it with a geometrical motif. It it applied them to various fields to develop design content for fashion cultural products that were Korean, modern, and competitive. For this purpose, this paper used Adobe Illustrator CS2 to turn the camellia flower into a motif and develop it into a pattern. Based on the realistic form of camellia flower, this paper set 3 basic motifs of new formative images, using graphic elements, such as omission of a form, simplification, overlapping, repetition, and reduction, and it also developed two transformed motifs by applying a different color to each motif. This paper repetitively arranged each motif in the background of a diamond shape, a square, and a circle, and it combined each motif with the patterns of marcel, stairs, and stripes, through which it expressed the combination of the geometrical patterns and the flower patterns. Through the application of repetitive and combined patterns of each motif, the enlargement and reduction of motifs, the repetition of motifs, the combined use of motifs, and the change in colors and layout, this paper used the motifs of various fashion cultural products, such as scarves, neckties, and T-shirts.

This article develops a nonclassical model to analyze bending response of squared perforated microbeams considering the coupled effect of microstructure and surface stress under different loading and boundary conditions, those are not be studied before. The corresponding material and geometrical characteristics of regularly squared perforated beams relative to fully filled beam are obtained analytically. The modified couple stress and the modified Gurtin-Murdoch surface elasticity models are adopted to incorporate the microstructure as well as the surface energy effects. The differential equations of equilibrium including the Poisson's effect are derived based on minimum potential energy. Exact closed form solution is obtained for bending behavior of the proposed model considering the classical and nonclassical boundary conditions for both uniformly distributed and concentrated loads. The proposed model is verified with results available in the literature. Influences of the microstructure length scale parameter, surface energy, beam thickness, boundary and loading conditions on the bending behavior of perforated microbeams are investigated. It is observed that microstructure and surface parameters are vital in investigation of the bending behavior of perforated microbeams. The obtained results are supportive for the design, analysis and manufacturing of perforated nanobeams that commonly used in nanoactuators, nanoswitches, MEMS and NEMS systems.
