An effective methodology is reported for the optimal design of multisite batch production/transportation and storage networks under uncertain demand forecasting. We assume that any given storage unit can store one material type which can be purchased from suppliers, internally produced, internally consumed, transported to or from other plant sites and/or sold to customers. We further assume that a storage unit is connected to all processing and transportation stages that consume/produce or move the material to which that storage unit is dedicated. Each processing stage transforms a set of feedstock materials or intermediates into a set of products with constant conversion factors. A batch transportation process can transfer one material or multiple materials at once between plant sites. The objective for optimization is to minimize the probability averaged total cost composed of raw material procurement, processing setup, transportation setup and inventory holding costs as well as the capital costs of processing stages and storage units. A novel production and inventory analysis formulation, the PSW(Periodic Square Wave) model, provides useful expressions for the upper/lower bounds and average level of the storage inventory. The expressions for the Kuhn-Tucker conditions of the optimization problem can be reduced to two sub-problems. The first yields analytical solutions for determining lot sizes while the second is a separable concave minimization network flow subproblem whose solution yields the average material flow rates through the networks for the given demand forecast scenario. The result of this study will contribute to the optimal design and operation of large-scale supply chain system.

The aim of this study was to gain an understanding of the element playfulness in fashion photographs related to openness and multiple significance in contemporary art. A total of 105 fashion photographs from US and UK Vogue magazine editorials and advertisements for the last five years were selected for the study. The photographs were analyzed in two main categories - the contextual element of themes, and the elements of visual expression; composition, models, objects and editing technology. The element of playfulness in the photographs were found to be divided into themes of infantile fantasy, social satire and situational dissonance, and elements of visual expression were found to express image distortion, expansion, exaggeration, reduction, and optical illusions. A photography type termed as infantile fantasy and social satire have descriptive characteristics and usually deliver the message by using models and objects to present a certain situation or express social satirical viewpoint and reflective attitude by using objects and photographic skills. A photography type termed as situational dissonance is characterized by immediately understood expressions and usually clarify the message by using a photographic technology such as editing the printed image or expect the model to express an exaggerated poses and ridiculous expressions, causing an optical illusion. Visually expressed and composed scene using composition, models, objects and editing technology is a specific character of photograph and due to the advances in computer editing technology it has been able to express the various playfulness.

Geisha's gorgeous kimonos and grotesque make-up was the object of envy to Japanese women. There is a line in the movie like "Kimonos to the Geisha is the same as colors to the painter." Likewise, splendid patterns and colorful kimonos were an indispensible method or symbol for showing their artistic accomplishments. The purpose of this study is to investigate concept and origin of Geisha and their dress and decoration, analyze the dress of the people which appear in the movie, , arrange the expression of Geisha's dress as a movie costume, compare the difference of the dress by the career of Geisha and look back the disappearing aesthetic sense of Geisha. First, since Geisha appeared for the first time in Kyoto in 1751, it has become the world-wide representative of Japanese woman's images so that its existence oneself has become the tradition. Second, Geisha created fashion of various clothes, adornments, and hair styles as a creator of the popularity. Third, the strict regulation without exception is applied in Geisha's clothing, make-up, and motion tuned Samisen, Japanese traditional strings, and there is some difference in their hair style and dress by age of Maiko. Fourth, it is famous for unique make-up that Geisha makes up their faces, necks, and shoulders white, newly paints eyes, nose, lip line like drawing a picture in a pure white paper. Geishas put a little make-up as they have a higher position. Fifth, a heroin, Chiyo, shows clothing as a maid, an apprentice Geisha-Maiko- and a formal Geisha according to time flow. The length of kimono, textures, and hair decorations are longer, more splendid, and are more various as time goes. On the other hand, her make-up is lighter.

This study analyzed gender-fluid images as expressions of feminism and gender identity expressed in fashion collections. As for the research method, this study searched the fashion collections, with the theme of feminism, utilizing key words related to feminism on an online portal, and collected the photo materials of fashion collections provided by vogue.com. This study classified the photo materials of 31 fashion collections, with the theme of feminism, into femininity, masculinity, androgyny, and avant-garde, according to the fashion design elements that divide gender identity. As a result of the classification, 326 photos were collected, in which gender identity was expressed ambiguously. This study reclassified the collected photos according to their fashion items and styles. As a result of the study, it was noticed that the fashion collections with the theme of feminism expressed the messages, using lettering graphic images, and performance. In addition, they showed a form in which men's collections and women's collections were integrated according to the change of the perceptions of gender identity, of feminism, and delivered body positive expressions, respecting differences and diversity as individual subjects, by casting diverse models in terms of age, body size, race, and culture. As for the gender identity expressed in the fashion collections, the gender-fluid images were classified into empowerment images, that expresses social rights and dignity; agender images that expresses the possibility of a gender-flexible transition; rational images that expresses the rational and practical characteristics that removed the boundary of fashion; and images of pro-sexism that expresses a new gender identity.

An effective methodology is reported for determining the optimal lot size of batch processing and storage networks which include uncertain demand forecasting. We assume that any given storage unit can store one material type which can be purchased from suppliers, internally produced, infernally consumed, transported to or from other sites and/or sold to customers. We further assume that a storage unit is connected to all processing and transportation stages that consume/produce or move the material to which that storage unit is dedicated. Each processing stage transforms a set of feedstock materials or intermediates into a set of products with constant conversion factors. A batch transportation process can transfer one material or multiple materials at once between sites. The objective for optimization is to minimize the probability averaged total cost composed of raw material procurement, processing setup, transportation setup and inventory holding costs as well as the capital costs of processing stages and storage units. A novel production and inventory analysis formulation, the PSW(Periodic Square Wave) model, provides useful expressions for the upper/lower bounds and average level of the storage inventory. The expressions for the Kuhn-Tucker conditions of the optimization problem can be reduced to two sub-problems. The first yields analytical solutions for determining lot sires while the second is a separable concave minimization network flow subproblem whose solution yields the average material flow rates through the networks for the given demand forecast scenario. The result of this study will contribute to the optimal design and operation of the global supply chain.

Since the onset of the 21st century, digital technology has been widely adopted in various fields of art; it has enabled artists or designers to try diverse and brand-new ways of expression in literally every possible field of art, including painting, sculpture, and other design work. Furniture design is no exception. From the initial design step to the final production of furniture, modern digital skills are broadly utilized, creating a whole new set of designs that would otherwise be hardly conceivable and realizing a highly efficient furniture-making mechanism. More recently, the 3D printing technique, which is called a 21st century alchemy, has been successfully commercialized and is getting more popular, heralding yet another innovative shift in the area of furniture design and production. In this context, this study discusses the background of the furniture design using digital technology, and identifies the correlations between the modern digital technology and furniture design by redefining the concept of such digital technology. By reviewing multiple real-life cases, some of the key digital expressions found in modern furniture design are also analyzed. This study aims at suggesting the reason why digital technology is significant and promising in diverse ways for the development of modern furniture design.

The purpose of this study is to develop a knitwear design with the potential for practical use through a combination of science and design by examining the concept and formative characteristics of fractal geometry and applying them to the development of 3D virtual clothing knitwear design. This study produced five main conclusions. First, the sub-concepts of "Repeatability," "Scale variability," and "complexity," which are based on self-similarity, appear together with simple regularity in the fractal formative characteristics shown in fashion design. Second, fashion fields apply fractal geometry in three-dimensional surface textures and optical textile patterns as a method of expression. Third, it was confirmed that various expressions can be created with fractal patterns by using the SDS-ONE APEX 3-4 design system; moreover, fractal patterns are a suitable design source for the development of Jacquard knitwear patterns. Fourth, in the development of knitted jacquard fractal patterns, by arranging the patterns in perspective, the effect of emphasizing or reducing the human body by optical illusion was shown. Fifth, a knit Jacquard structure with a pattern that exhibits fractal modeling characteristics and applying it to a 3D virtual clothing sample design reduces the time required for sample production while expanding the knit design's expression area and reducing costs. Thus, the clothing sample confirmed the effectiveness of practical knitwear design development.

Designs of Takashi Sugimoto suggested new concepts on the space after broking out fixed ideas, and attempted spatial expressions differently from existing interior decorations through independent thoughts and new interpretations. It is showing orientalism's influences strongly based on Japanese traditional beauty unlike western country's design trends. Takashi Sugimoto is implementing unique own design viewpoints by using materials in nature rather than artificial ones, and stressing extra ordinary view of the world having been edited with daily life through traditions and local cultures along with recycling old daily goods and wastes rather than pursuing modem and futuristic spatiality. Sugimoto thought that beautiful designs and uncommon ideas could be gotten from simple daily experiences, and thus materialized it with a technique of extraordinary daily life's implementation through such design viewpoints. Also, He pursues designs in which dense communications are made variously between spaces, space and user, and this becomes design techniques having been used mostly in his projects. It creates soft boundaries through using certain objet as an intermediate of doing communication or erasing physical boundaries, and then induces close communication within the space. This design viewpoints and techniques of Takashi Sugimoto have directed own discriminated designs nowadays.
