The present study approached the characteristics of various space compositions in contemporary residential architecture through the concept of ex-formality, and found that ex-formal spaces are composed through the variation of floor, wall, ceiling or roof and derived four types of ex-formal space composition - ex-cubic space composition using folding, plastic space composition using the plasticity of concrete, atypical space composition using geometric manipulation, and non linear space composition using digital technology. Based on this, additionally, we derived elements expressing the characteristics of ex-formal space composition, which are obliqueness, inclination, flexibility in ex-cubic space composition using folding, plasticity and fluidity in plastic space composition using the plasticity of concrete, ex-construction, dynamism and asymmetry in atypical space composition using geometric manipulation, and flexibility, fluidity, self similarity and plasticity in non linear space composition using digital technology. On the other hand, this study purposed to help understand various space expression patterns of contemporary residential architecture by analyzing how these types of ex-formal space composition and polysemous expression characteristics have been represented in contemporary residential architecture since the 1990s.

This paper proposes the use of decision tree classification for the measuring pattern recognition from industrial Computed Radiography(CR) images used in nondestructive evaluation(NDE) of steel-tubes. It appears that NDE problems are naturally desired to have machine learning techniques identify patterns and their classification. The attributes of decision tree are taken from NDE test procedure. Geometric features, such as radiative angle, gradient and distance, are estimated from the analysis of input image data. These factors are used to make it easy and accurate to classify an input object to one of the pre-specified classes on decision tree. This algerian is to simplify the characterization of NDE results and to facilitate the determination of features. The experimental results verify the usefulness of proposed algorithm.

$Premi\grave{e}re$ Vision is a leading textile collection held since 1973. In this study, textiles for 2004/05 F/W season in $Premi\grave{e}re$ Vision were analyzed at the various point of view, such as general trend, sub-theme, fiber content, color trend, structure, yarn trend, pattern, texture, decoration, finishing and other technical treatment, and functionality. There were three general trends; natural/ecology, geometry, and combination. Natural color and texture were widely used over the fabric exhibited, and irregularities expressed the natural trend of textiles. Geometric patterns were used for knit as well as for woven. Geometry expressed by various methods such as weaving, knitting, printing, shearing, embossing, and etc. However, geometry shown in this season was not a clear form expressed by weaving, but a blurry, irregular form expressed by various other methods such as knitting. The combination among heterogeneous fibers, yarns, colors, images, and textures was usual, however, the harmony among them was accomplished.

This paper presents nonlinear vibration analysis of a composite cylindrical shell. The core of the shell is made of functionally graded (FG) porous materials and layers is fabricated of carbon nanotubes (CNTs) reinforced nanocomposites. To increase the accuracy of results, neutral surface position is considered. First-order shear deformation theory is used as displacement field to derive the basic relations of equation motions. In addition, von-Karman nonlinear strains are employed to account geometric nonlinearity and to enhance the results' precision, the exact position of the neutral surface is considered. To governing the partial equations of motion, the Hamilton's principle is used. To reduce the equation motions into a nonlinear motion equation, the Galerkin's approach is employed. After that the nonlinear motion equation is solved by multiple scales method. Effect of various parameters such as volume fraction and distribution of CNTs along the thickness directions, different patterns and efficiency coefficients of porous materials, geometric characteristics and initial conditions on nonlinear to linear ratio of frequency is investigated.

The fashion industry that perceived the severity of environmental pollution, has sought various methods of sustainable fashion. However, most of the businesses paid attention to the development of materials using industrial waste, or vegan material. Thus, this study aims to present the methods for improvement in creativity for inversely developing the design from patterns and present new approaches by applying the contrarian development of proto to class under the limited condition of material concerning general design, selection of material, and production of sample. In the case of three student teams enrolled in the first semester of the second year, the fabric and used clothing donated by industry were used as material. The whole cut for cutting a single fabric in connected state, and Zero Wastes Design within a rectangular frame of fabric, upcycling of used clothes, and cutting out of Geometric Form are suggested. The team(A) produced a zero-wastes coat and whole-cut Pancho that could be variously represented. The team(B) produced two kinds of asymmetric dress by utilizing used check-patterned shirts through upcycling. The team(C) utilized the fabric in geometric forms such as rectangle, trapezoid, and atypical figure by drawing design within donated fabrics. The items were a dress, blouse, and skirt. Consequently, an opportunity for both academia and industry to present more concrete methods for sustainable fashion and deeply perceive the sustainable fashion is presented along with novel methods for creation by carrying out the composition of pattern and design at the same time.

The purpose of this study is to consider debates the reorganization of administrative districts and to investigate the role of maps in this debate during the early stage of French Revolution. For this, firstly, we examined the argument of reformers who attempted to change the administration system of the Old Regime. We found that physiocrats proposed map use for their attempt to reform this system. Secondly, we considered the debate on the theme of the new division of the kingdom on the basis of speeches or interventions delivered to the National Assembly. Robert de Hesseln's map, itself influenced by the geometric spirit shown by the map of Cassini, played an crucial role in the utopian ideas of revolutionaries who would divide France in administrative units of equal size geometric grid. Thirdly, the deputies decided the number and boundary of department on the basis of Hennequin's map. The final cut which resulted in very tense negotiations with local leaders was irregular polygons modeled on patterns of economic relations, and elements of relief and historical tradition. Fourthly, new administrative divisions are plotted on the map of Cassini and presented to the National Assembly. And it was declared as a new administrative division of France.

Although there are many ways to measure the diameter of a cylindrical object, in this study, the diameter of a cylindrical objects were measured by the geometric optical method and interference-diffraction method which are two kinds of tipical non-contact methods. In geometric optical method, the curved laser beam is formed on the cylindrical surface by spreading the inclined laser beam using the cylindrical lens. The curve is captured by CCD camera and the diameter is calculated by geometry. And the interference and diffraction patterns of investigated cylindrical objects are analyzed in interference-diffraction method. In this study, the cylindrical objects, whose diameters are $0.05\;mm\;\~\;100.50\;mm$ were measured by the geometric optical method and interference-diffraction method. The results show that in each method, the relative errors of the measurement are within $2\%$ and $1\%$, respectively and these non-contact methods can be applied in the quick measurement of many objects.

This study carefully explored today's preferable beauty images, analyzed Korean adult purchasing trends of functional underwear and market analysis of the most popular items and their designs. Information and methods are based largely on reference book material as well as analysis of real domestic data. The paper's research timeline simply spans the last three years, as in accordance with project parameters. Helping improve body shape, foundation literally means 'substructur' and 'base'. The formativeness in these adult foundations typically has three main category classifications. First, natural modern image. This is where we find natural beauty including that which embodies a cool modern sense. Here, you can often see such patterns as either stripes and dots, or simply no patterns at all. Colors are green, red-brown, incarnadine, or khaki from a natural or basic human body color. Its products are marketed as both solid and durable eco-friendly materials, and lace-seethrough. Fashion's natural modern image is undoubtedly the most popular style purchase choice among both genders. Second, sweet romantic image. This mainly consists of two concepts : a sweet and romantic theme, and visual appeal. Patterns include flowers, lips, heart, stars, candies and various other appealing characters. Its main colors are pink, yellow, red, purple, and violet. Products are decorated with laces, frills and ribbons. Since only men's semi-girdles carry such designs, this fashion foundation is largely a women's world. While men show an obvious interest in foundation, they still mostly prefer the choice of natural modern images. Third, mystic sexy image. This is defined as all feminine images of mysterious and classic sexual beauty. Patterns are variously expressed as paisley, flowers, and geometric. Colors are largely purple, blue-green, royal-blue, cobalt, and black. Products are commonly decorated with beading, spangles, hot-fixes and so on. While this image can be found in all kinds of women's foundations, it typically appears only in men's corsets and girdles.

This study is to enhance the competitiveness of the domestic cosmetic industry and provide basic materials needed for a design idea by analyzing perfume bottles designed by Rene Lalique. The methods of this study are documentary research and demonstrative research. The documentary research considered the theoretical background with a focus on related domestic and international literature, previous research, and Internet materials. The demonstrative research extracted photo materials of the bottle designs of Lalique from domestic and international web sites along with literature that classified them into shapes, colors, materials, and patterns that analyzed the general characteristics and chronologic changes. The results of this study are as follows. The curve-oriented shape was common and multi-colors were used more frequently than a single color in the 1910's. Colorless-transparent glass and a flower patterns were used frequently for materials and patterns, respectively. Lalique reflects this style in his bottle designs because the Art Nouveau effect in the 1910's. In the 1920's, curved and straight shapes had a similar percentage. The use of multi-colors and one type of glass bottle increased versus the 1910's. Similar to the 1910's, a flower pattern was used most frequently. This suggests that Lalique was influenced by the established Art Nouveau and was also interested in the Art Deco style, In the 1930's, an organic curved shape was common. Unlike the 1910's and 1920's, a single color was more common than multi-colors. The one type of glass bottle and a geometric pattern were common for materials and patterns, respectively. The Art Deco style was reflected in the bottle design of Lalique in the 1930's.
