스테인레스강은 철과 니켈, 크롬이 주 성분이다. 그 중에서 니켈이 차지하는 비율은 304계열 제품의 경우 8%에 불과하다. 그런데 STS 파이프 등 스테인레스 스틸 제품 원가의 60%를 차지하는 것이 니켈 가격이다. 결국 니켈 가격이 스테인레스 스틸 제품 가격을 좌지우지한다고 볼 수 있다. 우리 설비건설분야에서도 스테인레스 관련 제품이 공종에 따라 많이 투입되는 경우가 있다. 이번 호에서는 니켈의 국제 시세를 중심으로 스테인레스 제품 가격을 분석해 보고자 한다.

Even though geographical drawbacks of Netherlands, the De Stiji Movement has been acting extensively as a composite arts movement. Furthermore, because this movement has influenced on even field of architecture, Walter Gropius, who had led to establish the modern architecture at that time, was not also able to be excluded from the influence of De Stiji movement. As a result, his works after 1922 when De Stijl movement had been acting vividly, shows a part of De Stijl style and definitely has a difference via-a-via early of his works. Therefore, this study in this point of view is on the purpose of how De Stijl Movement influenced on Gropius' works as the ideology of place and concepts in the period of both De Stijl Movement and Modern architecture style were being formed together. Especially, this study will analyze Dessau Bauhaus Building, which is the most influenced by De Stijl Style in Gropius' works, into the way of how De Stijl. was embodied to this building.

The purpose of this study is to examine how fine art is received in fashion, and to contribute to the development of a creative fashion culture. In order to do this examination, this study focuses on the formative ideas of De Stijl which appeared in the early 20th century. In addition, this study presents examples of today's fashion that still reflects the formative ideas of De Stijl. The De stijl movement did not last for a long time, but it has had significant influence on modern art, and has been a source of inspiration to fashion designers since the Mondrian look was presented by Yves Saint Laurent in 1965. The study on the basis of De Stijl such as Neo-Plasticism of Piet Mondrian and Elementalism of Theo van Doesburg, has been conducted in this study. As a result, this study presents formative characteristics of the De Stijl group in fashion as follows: First, contemporary fashion designers have searched for proportion and thickness of lines and the side split using lines, a stylistic trait of an artist in the De Stijl group. Second, color scheme defined by the De Stijl group has been applied with modification to contemporary fashion. Modification and selective choice of the limited colors are for a contemporaneous style. Third, formative ideas of De Stijl, which strives to achieve the vision of Utopia, has turned up in contemporary fashion as a simple and minimal silhouette. Contemporary fashion has enhanced their aesthetic value by deriving not only a superficial expression but also plastic principle and philosophy from De stijl. It can be regarded as the fashion's ideal way to embrace style of art and it might be so described as a key to edifying artistic and creative attributes of fashion.

Dutch artist, Theo van Doesburg had shown short but strong experimental aesthetics in his works through De Stijl movement. He played a leading role for editing De Stijl magazine and performed various formative works such as painting, sculpture, and architecture. In 1923 he opened the first De Stijl exhibition cooperated with Cornelis van Eesteren. In this architecture exhibition he showed rich formal spirits of counter-construction in his major design works, that is Maison Particuliere and Maison D'artiste among three houses projects. Formal characteristics of counter-construction can be summed up under two categories, time and space. Analytical results are as follows; First, the characteristics of counter-construction related to time category include two types of two mode. One is linear aspect of time based on the viewer's movement. The other aspect is simultaneity caused by synoptical effect. These could be proved by the analysis of arrangement of color planes. Secondly, the spatial aspects of counter-construction are produced through two different ways of formal strategies. Van Doesburg arranged cubes in very irregular pattern. This treatment induces ambiguous void and creates feeling of subject's space. And, through deleting, shifting, and extending he could make dynamic spatial effect by interpenetration between in and out. This fluid space thus introduces movements of one's gaze and circulation. He denied traditional classical values which had ruled the western aesthetical discipline for centuries and believed that mankind can reach the realm of universal equilibrium by contrast and tension created by counter-construction. In this vein Theo van Doesburg was an avant-garde artist of Hegelian thoughts who adopted the dialectical method without following the formal characteristics from ancestors.

The cycle time in injection moulding greatly depends on the cooling time of the plastic part that is controlled by cooling channels. Cooling channels are required to facilitate the heat transfer rate from the die to the coolant without reducing the strength of the die. Employing layered manufacturing techniques (LMT), a die embedding conformal cooling channels can be fabricated directly while conventional cooling channels are usually made of straight drilled hole. Meanwhile, H13 tool steel is widely used as the die material because of its high thermal resistance and dimensional stability. However, H13 with a low thermal conductivity is not efficient for certain part geometries. In this context, the use of functionally graded materials (FGMs) between H13 and copper may circumvent a tradeoff between the strength and the heat transfer rate. This paper presents a method for modeling of conformal cooling channels made of FGMs.

Objective: The surface roughness of orthodontic materials is an essential factor that determines the coefficient of friction and the effectiveness of tooth movement. The aim of this study is to evaluate the surface roughness change of the brackets and wires after experimental sliding quantitatively. Methods: Before and after experimental sliding tests, the surface roughness of stainless steel brackets, ceramic brackets, stainless steel wires, and beta-titanium (TMA) wires were investigated and compared using atomic force microscopy (AFM). Results: After sliding tests, changes in the surface of the wire were greater than changes in the bracket slot surface. The surface roughness of the stainless steel bracket was not significantly increased after sliding test, whereas the roughness of ceramic brackets was decreased. Both the surface roughness of stainless steel and TMA wires were increased after sliding test. More changes were observed on the ceramic bracket than the stainless steel bracket. Conclusions: AFM is a valuable research tool when analyzing the surface roughness of the brackets and wires quantitatively.

The original members of the De Stijl group, formed in neutral Holland during the First World War, included the painters Piet Mondrian, Bart van Leck and Theo van Doesburg, and the architects J.J.P. Oud and Jan Wils. The aim of the group was to create a language of form and color applicable to every sphere of modern life. The means of expression selected by the De Stijl artists was rigorously restricted, using only vertical and horizontal lines with the right-angle created where they cross, and for color, black, white and the primaries- red, yellow and blue. Of these simple elements consisted the compositions painted by Mondrian and van Doesburg during the years around the end of the First World War, and the famous red-blue chair made by Gerrit Rietvelt in 1917. They did share a common influence, Cubism, and they both emphasized contemporaneity. Otherwise they were quite different movements, both in theory and practice, except lot one further point of similarity.

De Stijl in order to began in the Netherlands in 1917 is an art movement that becomes the theoretical background of modernism design was the foundation geometric abstraction. Steel design for that they offered a new paradigm at that time art, in various fields such as industrial design is still applied, especially works of De Stijl in the design area of urniture it became the beginning of the modern furniture. The starting point of this study is to analyze the two-dimensional representation characteristics to understand the background of the formation with the basic concepts of De Stijl. Therefore the generation of the surface to be displayed in the work of De Stijl and to analyze the divided element, and not if learn their expression characteristics. Also the line and the plane of the two-dimensional modeling properties of De Stijl, after described colors, and studied the characteristics of De Stjil writers for typical analyzes the moldability shown in their work, which based on, we try to present a new representation technique.

The purpose of this paper is to present an photoelasticity technique for measuring the displacement and stress distribution in particle assembly subjected to shallow foundation loading. Photoelastic measurement technique was employed to visualize the force transmission of a particle assembly. A model assembly bounded by a steel frame was built by stacking bi-dimensional circular particles made of polycarbonate elastomer. Each particle was coated by a thin photoelastic sheet so that the force transmission represented by bright light stripes can be visualized. In a contacted particle, both magnitude and orientation of principal stress difference can also be measured via the photoelasticity technique. The different distributions of the contact stresses at the initial loading and near the failure were quantitatively compared. The photoelastic patterns and displacement fields observed in the pre-failure state disappears immediately after the buckling of confined force chains.
