Frank Lloyd Wright is an architect who established the concept of organic architecture and in his organic architectures, he applied studies on the inflow, growth and development of natural elements of shapes, pursued naturalism in the shapes and functions and connected them organically with each other. His furniture as appeared in his constructions shows geometric plasticity based on naturalism and achieves an integration of shapes, materials and functions while forming a space. The organic nature from the viewpoint of digital which is a new concept of the 21st century is greatly affecting construction and furniture designs. Designs having new organic concepts are emerging in furniture which is organically related with construction to achieve organic harmony with new plastic spaces. Therefore, studies on Wright are more significant as a cornerstone for new theories under development.

The purpose of this study is to investigate the design methods and characteristics of papercraft fashion from 2001 to 2015. The study has been conducted through theoretical research and case study. Overall, types of papercraft expressions are classified into the following four categories: narrative papercraft fashion, organic papercraft fashion, variable papercraft fashion, and recycling papercraft fashion. The characteristics and aspects of each type of papercraft is described below. First, narrative papercraft fashion expresses as factual description of the natural environment. These works convey fantastic image by showing fairy tale animals or plants using paper folding or cutting. Second, organic papercraft fashion creates a futuristic shape by expressing organic parts in nature. Also, it often depicts future-oriented images by repeatedly representing organic shapes using uniform patterns in nature. Third, variable papercraft fashion expresses a variety of changing shapes through a flexible design based on the style of wearing. This variation may be accomplished through changeable dress connected to human gestures. Variable papercraft represents play-fulness, which conveys enjoyment to the wearer and the audience. Fourth, recycling papercraft fashion uses paper materials of the past, and recreates them into artworks through handicraft techniques. Recycling papercraft conveys high value added fashion by dissolving the material into pulp.

This study investigates and analyzes natural traits in Gaudi's architectural designs on the assumption that the naturalism in his architectural designs has been built heavily on regional cultural background. In particular, focusing on four buildings Gaudi designed in his late years, this study distinguishes between natural traits found in ornaments and details, and natural traits as organic expression of form. This study shows, first, with regard to natural traits in ornaments and details, organic motives were applied to patterns, plastic objects, and parts of the building. Second, natural traits in organic expression of form were reflected by typifying $Catalu\tilde{n}a$ regional nature, using curved lines of organic shapes and realizing lively natural creatures. It is remarkable that Gaudi developed his architectural designs as unique magic naturalism based on his imagination. And In this century 'Regional Culture' gets more important in architectural designs. Gaudi's architectural works can be appreciated to represent very well $Catalu\tilde{n}a$ regional cultural identity by using properly its natural motives and objects.

In this paper, a pretreatment method for a matrix in convex optimization is proposed to optimize the spectral reconstruction process of a disordered dispersion spectrometer. Unlike the reconstruction process of traditional spectrometers using Fourier transforms, the reconstruction process of disordered dispersion spectrometers involves solving a large-scale matrix equation. However, since the matrices in the matrix equation are obtained through measurement, they contain uncertainties due to out of band signals, background noise, rounding errors, temperature variations and so on. It is difficult to solve such a matrix equation by using ordinary nonstationary iterative methods, owing to instability problems. Although the smoothing Tikhonov regularization approach has the ability to approximatively solve the matrix equation and reconstruct most simple spectral shapes, it still suffers the limitations of reconstructing complex and irregular spectral shapes that are commonly used to distinguish different elements of detected targets with mixed substances by characteristic spectral peaks. Therefore, we propose a special pretreatment method for a matrix in convex optimization, which has been proved to be useful for reducing the condition number of matrices in the equation. In comparison with the reconstructed spectra gotten by the previous ordinary iterative method, the spectra obtained by the pretreatment method show obvious accuracy.

The floc formation, breakage and reformation of humic acid by inorganic (alum and PAC) and organic coagulants (cationic polyelectrolytes) at several conditions (pH, ionic strength and floc breakage time) were examined and compared among the coagulants at different conditions using a continuous optical monitoring method, with controlled mixing and stirring conditions. For alum, the shapes of formation, breakage and reformation curves at different pH (5 and 7) were different, but the shapes and the sizes of initial floc and reformed floc were nearly the same in the absence and presence of electrolytes at pH 7. For PAC, similar shapes of the curves were obtained at different pH and ionic strength, but the sizes were different, except for those of reformed flocs at different pH. However, for these coagulants, reformed flocs after floc breakage, occurred irreversibly for all the conditions used in this study. For organic coagulants, the time to attain the initial plateau floc size, the extent of floc strength at high shear rate and reversibility of reformed floes were different, depending floc formation mechanism. Especially, for the cationic polyelectrolyte forming humic flocs by charge neutralization or electrostatic patch effect mechanism, reformed flocs occurred reversibly, regardless of pH and floc breakage time, but occurred irreversibly in the presence of electrolytes.

In this study, we investigated the physical properties of powders made from agricultural byproducts, including rice straw, peanut husks, and garlic stems, to manufacture a new organic filler used for making paperboard. These materials were collected individually, and then we measured their chemical compositions. The byproducts were ground with a laboratory grinder and fractionated with 60-, 100-, and 200-mesh sieves to make many grades of organic fillers. After the grinding and fractionation, the yield, mean particle size, and particle size distribution of each grade were measured. Particle shapes were also investigated using a scanning electron microscope. The organic filler made from rice straw had the highest yield of the largest particle size group and higher contents of cellulose and hemicellulose than those made from peanut husks and garlic stems. The rice straw also showed more regular particle shapes and a lower aspect ratio than the other agricultural byproducts.

This study proposes the use of firework shapes to design fashion accessories in the judgment that they are appropriate for the expression of creative images in consideration of the display of fireworks as a kind of entertainment and a festive symbol. This study promotes the sustainable application of firework shapes to develop the designs of fashion culture items that feature a distinctive personality and uniqueness. In this present study, the proposed fashion accessory design was intended to create an entertaining new atmosphere that uses an Organic Light Emitting Diode (OLED) that draws attention as a futuristic display. In terms of methodology, a literature review of firework shapes and OLED was conducted; in addition, Adobe Illustrator CS2 and Adobe Photoshop CS2 were used to develop six different standard motive designs with formative design elements represented by a variety of firework shapes. Each of the six motifs was further expanded with different color combinations. Rich images are produced with the use of pink, blue, purple, green, yellow, orange, and red, in conjunction with various OLED effects to express the three-dimensional images of fireworks. The motifs are applied to three types of items: bags, bracelets, and necklaces. For the video images, evening and tote bags, pendants, and bangles were used. Shifting images and lights should produce unique images as well as satisfy the consumer desire for entertainment. The Adobe Image Ready software was used to present the motive of fireworks applied to the design of fashion accessories in video images but not in still-cut images due to physical constraints of this paper.

Organic solar cells have attracted extensive attention as a promising approach for cost-effective photovoltaic devices. However, organic solar cell has disadvantage of low power conversion efficiency in comparison with other type of solar cell, due to the recombination ratio of hole and electron is too large in the active layer. Thus we have change the surface structure of PEDOT:PSS layers to improve the current density by colloidal lithography method using various-size of polystyrene sphere. The two types of coating method were applied to fabricate the different pattern shape and height, such as spin coating and drop casting. Using the organic solvent, we easily eliminate the PS sphere and could make the varied pattern shapes by controlling the wet etching time. Also we have measured the electrical properties of patterned PEDOT:PSS film to check whether it is suitable for organic photovoltaics.

As the boundary between fashion and architecture is getting blurred, the interactions of the two fields are turning out abundant as well as essential. This study investigates the tectonic strategies in architectural fashion design as a novel aesthetic in the 21st century by combining literary survey and case analysis on architecture and contemporary fashion. The tectonic strategies in the works of architectural fashion designers were categorized as follows: organic geometry, technological garment construction, and independent space. Organic geometry transforms basic geometric shapes into subtle organic forms after being thrown on the body. Technological garment construction explores the garment structure and volume by applying the structural principle of suspension and fractal geometry. Independent space refers to maintaining the firm three-dimensionality of garment structure which keeps the distance from the body, assuming the similarity to architecture.

The purpose of this study is to investigate the design principles of organic integration on furniture design by Frank Lloyd Wright. He consistently pursued organic principles in interior design, furniture and equipments. He insisted that every elements of a building can be integrated into architecture as if architecture can be a part of the nature. The study surveyed and analyzed the examples of furniture design in Wright houses from the viewpoints of spacial and formal integration as well as organic evolution. The study finds the characteristics of organic integration on furniture design as follows. He designed built-in furniture as an important part of the house, which seemed to grow up from the architecture design and a part of a building. He also designed and arranged free-standing furniture as spacial device in open floor plan. Moreover, furniture design repeated same geometry, modules, and proportion system of house design in order to integrate Into the building. In addition, material and color of furniture follow those of architecture. Wright's furniture design had changed from heavy forms in his early prairie houses to light and practical shapes in his Usonian period.
