Reel-to-reel deposition of $Y_2O_3$ has been performed on Ni-5%W metal substrates using the RF-sputtering method. The epitaxial orientation of $Y_2O_3$ buffer layers to the base bi-axially textured substrate was well identified using ${\theta}-2{\theta}$, out-of-plane ($\omega$), and in-plane ($\phi$) scans in X-ray diffraction analysis. The optimization of $Y_2O_3$ seed layers in reel-to-reel fashion were investigated varying the deposition temperature, sputtering power, and pressure for its significant roles for the following buffer stacks and superconducting layers. $Y_2O_3$ were all grown epitaxially on bi-axially textured metal substrates at 380 watts and 5 mTorr in the temperature range of $600-740^{\circ}C$ with higher $Y_2O_3$ (400) intensities at ${\sim}710^{\circ}C$. It was found that the $\Delta\omega$ values were $1-2^{\circ}$ lower but the $\Delta\phi$ values were above $1^{\circ}$ higher than that of Ni-W substrates. As the sputtering power increased from 340 to 380 watts, $\Delta\omega$ and $\Delta\phi$ values showed decreased tendency. Even in the small window of deposition pressure of 3-7 mTorr, the $Y_2O_3$ (400) intensities increased and $\Delta\omega$ and $\Delta\phi$ values were reduced as sputtering pressure increased.

Art Deco is a decorative and eclectic design style, popularized at the interwar period. The term Art Deco derives from the Exposition Internationale des Arts D$\acute{e}$coratils et Industriels Modernes held in Paris in 1925. The aim of the exposition was to create new modern aesthetics. This exposition introduced the modern decorative and industrial art to the world and influenced all designers of area, including architects, interior designers, industrial designers, craftsmen, fashion designers, etc. Art Deco designers applied inspirations from a variety of sources and movements such as the Cubist abstract, the Neoclassical refinement, Egyptian exotic elements, Babylonian and Aztec temples, the machine aesthetic, avant-garde movements, etc to their modern works. Art Deco style rapidly spread all over the design areas nationwide in America. In Art Deco architecture, in particular, its inception was French but its domination was American. Skyscrapers, airplanes, automobiles, ocean liners, jazz, Hollywood film, streamline, and native Indian symbols are the defining features of American Art Deco. This study began from questions on how these features are expressed and stylized to decoration elements as the modern aesthetics in American Art Deco architecture. Thus, the purpose of the study is to find out the ornamental and eclectic factors of Art Deco style and to define a concept of the modernity and the regionalism of Art Deco architecture in America. This article provides an overview of the decoration style of Art Deco architecture in America through the analysis of ornamental and eclectic factors reflecting diverse roots. It also analyzes the wide variety of building examples of American Art Deco which represent regionalism. In addition, this study focuses on Art Deco architecture in Miami, Florida. Miami is one of typical cities that has the most unique regional aspects of 1920's to 1940's in Art Deco architecture. Miami Art Deco architecture reveals the tropical and nautical references such as streamlined and curved walls, exotic animal motifs, flora and fauna motifs, and marine motifs: use of glass block, porthole window, terra-cotta, and pastel color stucco.

Purpose: The present study investigated the impact of 2 different suture techniques, the conventional crossed mattress suture (X suture) and the novel hidden X suture, for alveolar ridge preservation (ARP) with an open healing approach. Methods: This study was a prospective randomized controlled clinical trial. Fourteen patients requiring extraction of the maxillary or mandibular posterior teeth were enrolled and allocated into 2 groups. After extraction, demineralized bovine bone matrix mixed with 10% collagen (DBBM-C) was grafted and the socket was covered by porcine collagen membrane in a double-layer fashion. No attempt to obtain primary closure was made. The hidden X suture and conventional X suture techniques were performed in the test and control groups, respectively. Cone-beam computed tomographic (CBCT) images were taken immediately after the graft procedure and before implant surgery 4 months later. Additionally, the change in the mucogingival junction (MGJ) position was measured and was compared after extraction, after suturing, and 4 months after the operation. Results: All sites healed without any complications. Clinical evaluations showed that the MGJ line shifted to the lingual side immediately after the application of the X suture by $1.56{\pm}0.90mm$ in the control group, while the application of the hidden X suture rather pushed the MGJ line slightly to the buccal side by $0.25{\pm}0.66mm$. It was demonstrated that the amount of keratinized tissue (KT) preserved on the buccal side was significantly greater in the hidden X suture group 4 months after the procedure (P<0.05). Radiographic analysis showed that the hidden X suture had a significant effect in preserving horizontal width and minimizing vertical reduction in comparison to X suture (P<0.05). Conclusions: Our study provided clinical and radiographic verification of the efficacy of the hidden X suture in preserving the width of KT and the dimensions of the alveolar ridge after ARP.

Reinforced concrete beams can be strengthened in a structural retrofit process by attaching steel plates to their sides by bolting. Whilst bolting produces a confident degree of shear connection under conditions of either static or seismic overload, the plates are susceptible to local buckling. The aim of this paper is to investigate the local buckling of unilaterally-restrained plates with point supports in a generic fashion, but with particular emphasis on the provision of the restraints by bolts, and on the geometric configuration of these bolts on the buckling loads. A numerical procedure, which is based on the Rayleigh-Ritz method in conjunction with the technique of Lagrange multipliers, is developed to study the unilateral local buckling of rectangular plates bolted to the concrete with various arrangements of the pattern of bolting. A sufficient number of separable polynomials are used to define the flexural buckling displacements, while the restraint condition is modelled as a tensionless foundation using a penalty function approach to this form of mathematical contact problem. The additional constraint provided by the bolts is also modelled using Lagrange multipliers, providing an efficacious method of numerical analysis. Local buckling coefficients are determined for a range of bolting configurations, and these are compared with those developed elsewhere with simplifying assumptions. The interaction of the actions in bolted plates during buckling is also considered.

The present study attempted to compare the behavioral patterns and attitudes of American and Korean female students toward apparel ads in magazines in relation to their physical self-concept. The study used a self-administered questionnaire. The sample consisted of 730 female students majoring in the fields related to clothing and textiles : 310 American students at six colleges and universities located in the west, northeast and southwest parts of the U.S., and 412 Korean students at four Seoul-based universities. Likert scales were used for most measures with 1=never or very unimportant and 5 =always or very important. Physical self-concept was measured on the basis of W. S. Jung's Standardized Self-concept Test and Tennessee Self-concept Scale. Surreys were back translated for validity. Percentage, t-test, Contingency Tables and Chi-square were used for the analysis of the data. Results are as follows : (1) Korean students read more magazines than U.S. students, however, Vogue was the most popular for both groups. (2) Those with a high sense of Physical self-concept read more magazines. for both countries. (3) American students'attitudes toward apparel ads in magazines were similar, regardless of whether their sense of physical self-concept was high or low. For Koreans, those with higher sense of physical self-concept showed greater interest in magazine ads, consulted magazines for fashion trends, found ads more useful, and more often expressed satisfaction with the ads, than the lower self-concept group. (4) Korean students cited a lack of information in ads while American students felt body types of models were unrealistic. Both Koreans and Americans in the higher self-concept group expressed a greater level of dissatisfaction with apparel ads in magazines. (5) Advertisers should attempt to again a deeper understanding of the socio-psychological characteristics of their readership as self-concept appears to be related to several magazine readership attitudes and behaviors. Magazines targeting Americans might consider the importance of coordination and merchandising. Apparel ads targeting Korean should consider the importance of company ads.

The purpose of this study is to explore ways toward the hat design development by looking into the formative and aesthetic characteristics of the works of Philip Treacy, the designer who raised hats to one of the important fashion accessories. This study concretely investigates the formative characteristics of Treacy's hats in terms of shapes, materials, colours and decorations. According to this study, the shape of his hats shows the natural and specific objects in three dimensions, not in basic shape of hats. He uses combination of a variety of materials, adding unique materials to existing ones, so that they not only create a specific atmosphere but also extend the limitation which used to be thought as materials for hats. In the field of colour, he mainly used black and white until 1999, but since 2000 he has been using vivid and splendid colors. And he uses feathers or nets for decorations of the hats. As the result of the comprehensive analysis of Treacy's works, this study characterizes his works by surrealistic, three-dimensional, rhythmic and future-oriented. Therefore, Philip Treacy's hat design can be defined three dimensional considering the formative beauty, and can be characterized by use of unique materials, vivid & bold colours, moderate decorations, f variety of lines, and asymmetrical structures. These characteristics show surrealistic, three-dimensional and futuristic message which rhythm can be felt. He presents unlimited capability in hat designs as a representative of human being's basic will for creating new ones beyond this real world. It is considered that this study can help broaden the limitation of the hat design which used to repeat simple forms in the Past and help explore ways for developmental direction of hat design in the future.

Performance art is an integrated genre of different art areas, and make-up is a visual art area to give lively effects to the performance art, which makes actors and actresses changed into the characters of plays. It can be said to be a kind of deliverer of idea to help effectively understand the contents of the performance. When we are in the world abundant in various cultures and innumerable styles of expression of different countries, we should rediscover the value of the beauty of our traditional masks that have represented the emotion and thought of Han nation, which we can find in play culture of our ancestors that has kept our ancestors' value system. That's the way we can get continuous life force and competitive power of our traditional culture. The Korean traditional masks haven't only been for the prevention of bad luck and the prayer of fortune, but also well expressed Korean people's looks, features and personalities according to the roles. They are excellent artistic works in themselves, and many studies have been performed on the analyses and uses of the features of the masks in various fields due to their good expression of different cultural aspects, while the studies in the light of make-up are rarely performed. Therefore, this article aims to analyze the features of the Korean traditional masks and, by using this analysis, to present effective make-up designs in outdoor performances through a stage performance. In addition, this article also tries to present the orientation of make-up as an expression of artistic image, and to expand the expression area of make-up by using the Korean traditional masks in the light of make-up. For this purpose, I examined the related literature and the precedent study materials to find the origin and kinds of the Korean traditional masks, and analyzed the features of the masks. Furthermore, I established the make-up design plan using the material features of the Korean traditional masks by analyzing the characters in actual performance works, and presented the photos of works actually performed.

The cotton fabric armour for lower class soldiers can be found from the historical records of the mid-Joseon Korea. And the records show that the form and the structure of the armour was modified in the late 19th century in order to provide better protection from gunshots for the soldiers in the midst of the invasions from the West. This is a survey and research of the only artifact of the cotton fabric armour remaining in Korea - for its form, dimensions, and design. Using the historical records as reference, we can confirm the structure and characteristics of the cotton fabric armour of the Joseon period. This cotton fabric armour, preserved in National Museum of Korea, is a vest-type armour made of 30 layers of cotton. On the right shoulder, there is a button for tying knots and strings were tied under both armpits. On the surface of the cotton fabric armour there were some characters and patterns stamped in black. Presently, this artifact in Korea is the only specimen relic of its sort, but there are some other related relics in foreign countries including helmets and belts. Continuous researches would help extend the scope of armour study beyond the traditional researches that only focuses on the armours of the officials, thus helping us to understand the military costumes in traditional Korea.
