The statistical analysis of the feature extraction and the neural networks are proposed to recognize a human face. In the preprocessing step, the normalized skin color map with Gaussian functions is employed to extract the region of face candidate. The feature information in the region of the face candidate is used to detect the face region. In the recognition step, as a tested, the 120 images of 10 persons are trained by the backpropagation algorithm. The images of each person are obtained from the various direction, pose, and facial expression. Input variables of the neural networks are the geometrical feature information and the feature information that comes from the eigenface spaces. The simulation results of 10 persons show that the proposed method yields high recognition rates.

A general geometrically non-linear model for lateral-torsional buckling of thick and thin-walled FGM box beams is presented. In this model primary and secondary torsional warping and shear effects are taken into account. The coupled equilibrium equations obtained from Galerkin's method are derived and the corresponding tangent matrix is used to compute the critical moments. General expression is derived for the lateral-torsional buckling load of unshearable FGM beams. The results are validated by comparison with a 3D finite element simulation using the code ABAQUS. The influences of the geometrical characteristics and the shear effects on the buckling loads are demonstrated through several case studies.

The thermal buckling temperature values of the graded carbon nanotube reinforced composite shell structure is explored using higher-order mid-plane kinematics and multiscale constituent modeling under two different thermal fields. The critical values of buckling temperature including the effect of in-plane thermal loading are computed numerically by minimizing the final energy expression through a linear isoparametric finite element technique. The governing equation of the multiscale nanocomposite is derived via the variational principle including the geometrical distortion through Green-Lagrange strain. Additionally, the model includes different grading patterns of nanotube through the panel thickness to improve the structural strength. The reliability and accuracy of the developed finite element model are varified by comparison and convergence studies. Finally, the applicability of present developed model was highlight by enlighten several numerical examples for various type shell geometries and design parameters.

The modern fashion contains the religious factors or theories out of numerous cultural traits. Shamanism is a product of the very complicated combination of diversified cultural phenomena and whose traits are depicted as spiritual and artistic forms, reflecting on the materialism culture, social relations, customs, and religious faith. The Shamanism that lies in the life of humans gives much impact on their clothing life up to date, consciously or nonconsciously as well. The Shamanism clothing studied as yet has been focused on the costumes that a Shamanism priest and a shaman, the principal Shamanism performer wears and on the symbolic meaning or formativeness of the traditional shaman clothing that is only confined to certain local regions. The Shamanism in the modern costume influences not only on the traditional clothing unique to shaman but also on the other apparels in a widely extended sense. Nevertheless, the research on the modern costumes related to Shamanism is yet to be progressed. In this context, it is believed that the examination of Shamanism interrelated with a contemporary clothing expression is needed. This work would take a look specifically at how the Shamanism is given in the modern clothing fashion and review the inherent aesthetic characteristics. A fact was driven through this study that the shamanism shown in fashion is not only expressed in the modern style of shaman clothing but also unconsciously absorbed in the fashion on the whole. A finding was also revealed that the geometrical and abstract expression, the implication of animistic components, and the application of inherent shaman's costume on to design in regard to clothing are related to a view point of studying about shamanism. The meaning in each expressive method is focused on the superhumanistic desire of shamanism.

This subject is about the research of Shanghai Art Deco in the aspect of architectural decoration and seek to offers an examination and analysis of the characteristics related to the Art Deco design, which appeared and dominated the field of design from 1910s to 1904s in Shanghai. Study method is a theoretical consideration of reference and gathering data through field trip. In order to carry out this subject, this study will research following factors. First, factors related to Art Deco such as the period of origin, background, spirit, aesthetics, design characteristics. This is followed by the influence of Art Deco movement begun in 1925. Second, the background of Shanghai Art Deco architecture style was studied. Third, the case studies of Shanghai Art Deco Architecture and interior decoration were researched by the expressive factors which were divided by style, form, material and color. As a result early style had compradore style about 1900, later reactionism prevailed of 1920 affected by European Art Deco. Skyscraper style was built and architecture developed with racial characteristics. It has vertical and streamline form of typical Art Deco and strengthen geometrical motive in architectural expression. It appeared naturally and has the contrast of different material in material expression. It has effect on strong color as using highborn and brilliant color in color expression. They appeared chinese national spirit by using 'ot painting' in western oriented furniture. The purpose of such an examination is to classify, understand and validate Shanghai artistic and socio-cultural heritage in order to better appreciate the life philosophy of Shanghai and re-discover their basic roots. Though it began as a Western cultural movement, it is the purpose of this study to discover the inherent orientalism in its basic formative spirit.

The purpose of this study is the development of an experimental design that aims to implement three-dimensional fashion design by observing the human body, extracting and combining geometric shapes and forms, and focusing on attempts to decompose the geometry of the human body in art history. Considering the characteristics of fashion design, which inevitably reflect human images visually, this study considered works by deriving geometric shapes and forms of the human body and focusing on decomposition and combination to apply them to fashion design. The results obtained through the development of fashion design through decomposition and combination based on geometric human body analysis are as follows. First, geometric analysis of the human body as an object of expression continues from the history of Cubism to modern fashion design. Second, the geometric shapes of the human body that appear in contemporary fashion design maximize visual effects through three-dimensional composition, emphasizing simplicity while showing originality through various expressions. Third, when exploring the geometric shapes of a moving human body, it was possible to extract a wide variety of shapes and forms through drawing and simplifying the human body's movements. Fourth, the formative method of fashion design was introduced and used for the aesthetic combination of objects for fashion design through decomposition and combination. This study was able to show unique and diverse combinations of visually concise and ordered geometric shapes in the expression of fashion design by decomposing and combining them. The significance of these geometric forms is that they can diversify formative informativeness in the expression of fashion design with modern compositional beauty.

A Study on the color comparison of Korean Saek-dong and Italian futurist fashion It is generally recognized that the color scheme and its characteristics as a product of living culture are strongly reflected in clothing. This study concentrates on the color comparison of Korean Saek-dong which has been used in traditional Korean clothing and Italian futurist fashion which showed dynamic characteristics and brilliant colors. The purpose of this study is to investigate the external format, emotions, functions and meanings of the colors in Korean Saek-dong and Futurist fashion, and to find similarities and differences between them. The results of the study are as follows. The similarities between them are harmony of vivid colors like a rainbow, no-use of black color and expression of rhythm through repeated geometrical shapes. They have been used as festive costumes and have implied meaning of happiness and pleasure. The differences, in the external formats, are as follows. Korean Saek-dong has striped patterns including the color white, and has regular distances among the stripes. But, Futurist fashion includes luminous or fluorescent colors and metallic colors. In addition, it has repeated motifs of geometrical shapes and geometrically divided areas. While Saek-dong expresses Sangsaeng through the conceptual use of color, Futurist fashion shows simultaneity, speed and dynamics through spiritual functions of crossing and inter-penetration. In emotional aspect, Saek-dong expresses pleasure of children's mind and Futurist fashion expresses pleasure of city. In functional aspect, Saek-dons expresses a concept of ceremonial beauty, which is spiritual and symbolizes good auspices, holiness and sorcery. So it is used for ceremonial costume. But, Futurist fashion reflects the harmony of colors created from modem and urban images and shows the willingness and emotion of solving futuristic avant-garde, modernity, dynamics, transformation and bellicosity. So it is used for daywear. While Saek-dong represents succession of tradition, Futurist fashion represents resistance of tradition in cultural aspects.

This study examines the morphological expression type and formative characteristics of women's shoes designs that integrate 3D printing technology. The results of the study are as follows. First, the morphological expression types of contemporary shoes that integrate 3D printing technology express a structural form created by repetition. Second, it expresses a dynamic form, which combines organic curves that create an external volume. Third, it expresses a surrealistic form centered on an object with the creation of a unique shape that utilizes objects easily experienced in local surroundings. Fourth, it expresses a hybrid form on a partial derivation. Each of the other system's components are fused to create another beauty that develops a new value in a colorful variation on the shape of 3D printing shoes. The first formative characteristic of women's shoes designs that integrate 3D printing technology is continuity. This creates an invisible form of a new space through repetitive unidirectional layers with a gradual expansion of a unitary seamless curves. Second, it is an exaggeration. This exaggeration elicits an enormous aesthetic quality by structuring the outward space in the difference of the volume formed based on the maximization of a specific part and the volume of a line's atypical movement. Third, it is a decoration. It displays the beauty of a decoration that evokes a unique artistic inspiration by partial unification or a practical representation of a specific form. This can also be seen as superimposing a 3D printing figure that has an outstanding shape onto part of the fashion shoes. Fourth, it concerns a geometrical characteristic that formulates a new structure with rationality in combining basic shapes such as circles, triangles and squares with lines, hexagons and interconnected geometrical forms to create a multi-dimensional space for shoes in a systematic and unidirectional pattern.
