Draper and Lawrence (1965a) have given mixture designs for three factors when all the mixture components can vary on the entire factor space so that the region of interest is an equilateral triangle in two dimensions. In this paper their work is extended to the cases when the region of interest is an echelon, parallelogram, pentagon or hexagon, because of the restirctions imposed on some or all of the mixture components. The principles used in the choice of appropriate designs are those originally introduced by Box and Draper(1959). It is assumed that a response surface equation of first order is fitted, but there is a possibility of bias error due to presence of second order terms in the true model. Minimum bias designs for several cases of restricted regions of interest are illustrated.

This study dealing with the Italian futurist and Russian constructivist costume designs which aimed for new fashion design freed from the conventional meanings of fashion and explore the artistic purpose reflected within the designs expressed differently according to cultural and regional differences in order examine the early 20th century Avant-grade costume designs. The scope of this study is limited to the 1910s to the 1930s when the Italian futurism and the Russian constructivism were originated and were most active. This monograph focused on the works of the Italian futurists, Giacomo Balla who declared the 'Manifesto delle moda minile futurista', Fortunato Depero, and Thayaht who suggested a new direction for the futurist, and on the works of the Russian constructivists Alexander Rodchenko, Varvara Stepanova and Liubov Popova. As an one method of investigated, this paper is used materials of various sources to examine their features. Futurists costume designs expressed a radical conception of progress and their source of aesthetics was dynamism. The concept of 'power' which was the basis of the futurists was incorporated in the costumes while non-symmetrical cut-outs and bright and vivid colors completed the futurist costume designs. Moreover the Russian constructivists brought advances in the field of fabric and textile designs. What was particularly interesting about the Russian constructivist costumes was that the artists worked at the textile mills themselves, directly involved in the designs and manufacturing of fabric, developing an advancement in textile and a new understanding of costume. Furthermore, many Russian artists settled in Paris, actively participating in the fashion industry, and therefore, they have greatly contributed to the development of the early 20th century Avant-garde costume designs.

The most important issue of today in design genre is the comprehensive design that overcomes the limitations of the rational and logical designs of functionalism that has had influences in entire 20th century and encompasses even the emotional aspect of humans. The emotional design factors in furniture designs will be analyzed in order to analyze their effects and values on the consumers of present times. The emotional uses of the patterns with the motive of nature expressing papers, flowers, wood textures, natural phenomena etc as they are and the colors with the vivid feeling of primary colors represent more dynamic and cheerful life style and the designs are characterized by the warm primary colors that give the feeling that the nature has been transferred to the designs as it is. Diverse materials such as leather, fur, fabric and the materials with soft and flexible feeling such as silicone material have been used more widely and they are used as the materials expressing freedom not being formalized. The designs that can produce diverse spaces desired by users by gathering unit modules can be said to be the outcome of the emotional designs combined with the needs of modern peoples that aspire their own designs.

The purpose of this study was to compare the differences in recognition of sexy body parts and apparel designs by age and to discover the correlations between sexy body parts and apparel designs. Data were collected through a survey of 265 males and 303 females. Analyses included t-tests, f-tests, and Pearson's correlations. The results were as followings; 1. The 20's-30's age group found female body parts were sexier than 40's-50's did. 20's-30's believed the male body was sexier than 40's-50's did. 2. The age groups found men's clothing designs were different by different age groups. Also, differences in female clothing designs were recognized by different age groups. 3. The 40's-50's age group recognized see-through sexier than 20's-30s did. Differences in sexy color recognition by age were also found. 4. There were correlations between most of sexy body parts and designs which emphasized the body parts. The results of this study show the differences in recognition and correlation by age. The results may be applied to developing sexy designs for different targeted age groups.

At the beginning of the $20^{th}$ century, Cartier developed Art Deco jewelry designs that have been used as design inspirations to this day. The purpose of this study is to analyze the characteristics of the Art Deco jewelry designs of Cartier in the early $20^{th}$ century. Regarding the research method, this study explored the jewelry designs from 1904 to 1939 by extracting 288 analysis subjects from Cartier's exhibitions, auction picture books, and foreign books, and analyzed the characteristics in terms of design motifs, colors and materials. The results of the study are as follows. Regarding the design motifs, 73% were geometric motifs, and 66% were a combination of circular shapes and polygons, the most frequent. In terms of colors, 69% were chromatic in color, and vivid colors were mostly used in the order of red (24%), - green (19%), and - blue (14%). Of the materials, 92% of the metals consisted of platinum, and gemstones were used in the order of diamonds (41%), - onyx (13%), - emeralds (11%), - rubies (9%), and - sapphires (8%). In the early $20^{th}$ century, Cartier's Art Deco jewelry designs featured abstract and geometric motifs, vivid colors and strong contrasts, platinum and precious gemstones. This study is meaningful in that it explores the competitiveness of Cartier's designs and provides practical ideas to combine Art Deco style with contemporary jewelry designs successfully.

In a general fractional factorial design, the n-levels of a factor are coded by the $n^{th}$ roots of the unity. Pistone and Rogantin (2007) gave a full generalization to mixed-level designs of the theory of the polynomial indicator function using this device. This article discusses the optimal blocking scheme for nonregular designs. According to hierarchical principle, the minimum aberration (MA) has been used as an important criterion for selecting blocked regular fractional factorial designs. MA criterion is mainly based on the defining contrast groups, which only exist for regular designs but not for nonregular designs. Recently, Cheng et al. (2004) adapted the generalized (G)-MA criterion discussed by Tang and Deng (1999) in studying $2^p$ optimal blocking scheme for nonregular factorial designs. The approach is based on the method of replacement by assigning $2^p$ blocks the distinct level combinations in the column with different blocks. However, when blocking level is not a power of two, we have no clue yet in any sense. As an example, suppose we experiment during 3 days for 12-run Plackett-Burman design. How can we arrange the 12-runs into the three blocks? To solve the problem, we apply G-MA criterion to nonregular mixed-level blocked scheme via the mixed-level indicator function and give an answer for the question.

Andree Potman is one of the few French female interior designers who has successfully extended her design territory beyond France into a more global context. Unlike other interior designers Potman has a very unique and eclectic background. She has studied music, worked as a journalist, talented in redeveloping designs that were unknown at that time such as design's of Eileen Gray, Mallet-Stevenson, and many more. Starting her career as an interior designer we can see her designs not only in France but also in many other countries such as America, Japan, and Germany. However her name is not that familiar to the designers in Korea. Therefore the current study focuses on the introduction and understanding of Potman's designs in regards to the relationship between interior space and objets that have made her designs so called 'Potman Style'. In order to accomplish the objective the researcher first studied means and use of ejects in interior space and next examined characteristics of Potman's designs including lighting fixtures, products, furnitures, and Interior designs. Finally, by using constant comparative analysis four categories (esthetics of emptiness, repetition of geometric forms, contrast in style, and focus with lighting) of design methods are revealed as the characteristics of interior elements as objects in Andree Potman's interior designs.
