Composite resins are the most commonly used dental restorative materials after minimally invasive dental procedures, and they offer an aesthetically pleasing appearance. An ideal composite restorative material should have wear properties similar to those of tooth tissues. Wear refers to the damaging, gradual loss or deformation of a material at solid surfaces. Depending on the mechanism of action, wear can be categorized as abrasive, adhesive, fatigue, or corrosive. Currently used composite resins cover a wide range of materials with diverse properties, offering dental clinicians multiple choices for anterior and posterior teeth. In order to improve the mechanical properties and the resistance to wear of composite materials, many types of monomers, silane coupling agents, and reinforcing fillers have been developed. Since resistance to wear is an important factor in determining the clinical success of composite resins, the purpose of this literature review was to define what constitutes wear. The discussion focuses on factors that contribute to the extent of wear as well as to the prevention of wear. Finally, the behavior of various types of existing composite materials such as nanohybrid, flowable, and computer-assisted design/computer-assisted manufacturing materials, was investigated, along with the factors that may cause or contribute to their wear.

This is the precedent study on the modern fashion design using Korean emotions, and its aim is to study the expressions in the modern fashion based on 'Jeong-Jung-Dong' idea from Korean dancing, which implicates the Korean emotion deeply among the artworks and give essence similar to the clothing. 'Jeong-Jung-Dong', a unique idea, in the Korean traditional dancing is the philosophy that involve the paradox expression, 'Movement in Silence,' which represented the emotion of Korean dancing for a long time. The main characteristics deducted in 'Jeong-Jung-Dong' were 1) the incomplete and complete by atypical, 2) the beauty of temperance by symbolism, and 3) amusing mutual relationship. Upon the analysis results of previous studies on the expressions in the modern fashion with 'Jeong-Jung-Dong', they demonstrated the atypical expressed by metaphor, symbolic expression through margin, and mutual relational table by harmony. The analysis of modern fashion expression by 'Jeong-Jung-Dong', which is a philosophical idea in the Korean dancing, could highlight the new way of looking at the clothing and systemize the theory on the Korean emotion to seek the effective expression of artistic features for the culture together with introduction of our unique emotion in the creative design process by understanding of humanitarian and philosophical ideologies to be utilized in the future Fashion Design.

As designs that simulate man's five wits are important, all five senses used are complex. Tactil value by Bernard Berenson means that the object in fine art makes the spectator feel like his or her finger is touching something, although the spectator is distant from the art piece. Especially as costumes have a relationship with the flexible skin and moving body, tactile modality and tactile value is more important. In order to analyze how Madeleine Vionnet realized a new femininity through the application of the principal of tactile value to dress design and in order to define tactile value in the field of fashion, this study examines the theory of tactile value, sculpture, painting, contemporary art, and product design as well as the design of Madeleine Vionnet from 1925 to 1937 because she was in the fashion business enlarging dress shops in New york during this period. The shape of Madeleine Vionnet's dresses made the concealed body alive through organic curves pressed against the body from cuts and dissections based on the anatomy of a supple body with curves and movement. In the garments, soft physical characteristics or the glossy touch of silk or pile textile imitated smooth skin while colors similar to a woman's eye, hair, and skin color continue the impression of the dress extending to the body through these design elements, Madeleine Vionnet's dresses reinforce the will to touch female body hidden under the dress by tactile values, not by the body's modification or visual exposure.

This study describes the recognition and the application of materials corresponding to the formative language of landscape design as the formative process of creating connote forms and meanings in a space. The purpose of this study is to propose the significance of materiality not only for conveying the meaning of landscape but also for providing expanded experience through synesthetic perception. The study consists of two parts: (1) The concept of materiality in landscape architecture is studied in three categories, which are divided in chronological order when the recognition of materials was changed. (2) Based on this exploration of the concept of materiality and the ways of expressing it that have developed from landscape arts to landscape architecture, the significance of materiality as the medium of contemporary landscape design is proposed. Breaking from previous technical and engineering approaches to materials and from a vision-centered recognition of materials, this study focuses on aesthetic and semantic aspects of materiality and is based on multidimensional recognition though synesthesia. Materiality has significance not only as the dynamic medium that carries the meaning of landscape by providing connections with the surrounding environmental context, but also as the engagement medium that expands observers' experiences with the environment through synesthesia. The study of materiality as the medium of landscape design would contribute to expanding the scope of the language of landscape design and to expressing the meaning of landscape through materiality being revealed on the basis of converted recognition of materials.

Freeway corridors consist of urban freeways and parallel arterials that drivers can use alternatively. Ramp metering in freeways and signal control in arterials are contemporary traffic control methods that have been developed and applied in order to improve traffic conditions of freeway corridors. However, most of the existing studies have focused on either optimal ramp metering in freeways, or progression signal strategies between arterial intersections. There have been no traffic control systems in Korea that integrates the freeway ramp metering and arterial signal control. The effective control strategies for freeway operations may cause negative effects on arterial traffic. On the other hand, traffic congestion and bottleneck phenomenon of arterials due to the increasing peak-hour travel demand and ineffective signal operation may generate an accessibility problem to freeway ramps. Thus, the main function of the freeway which is the through-traffic process has not been successful. The purpose of this study is to develop an integrated control model that connects freeway ramp metering systems and signal control systems in arterial intersections. And Optimization of integrated control model which consists of ramp metering and signal control is another purpose. The design of experiment, neural network, and simulated annealing are used for optimization.

Based upon literature survey, this research aims to analyze western children's clothing and characteristics over centuries. It was not until the 18th century that children were given serious consideration and that fabrication of clothing began to be designed only for children. The very first clothes which revolutionized children's wear was 'a la matelot' in the 18th century which freed children from physical restriction, recognized gender difference, and sailor suit became popular among all sexes and adopted as school uniform. And then children's clothing was shortened in length and adopted tubular silhouette, which allowed greater comfort and movement. The 20th century saw children's wear reform to be carried out after the World War II due to invention of synthetic fiber, easy care dress material, mass production system and sophistication of marketing methods. Further evidence of improvement of children's social status can be found in contemporary designs: for example, 'casualized' wear, 'character design' which reflects children's psychology and 'family look' which is designed to be worn with mothers. This evolution of children's clothing within western dressing support the view that children's clothing is not a miniature of adult wear but it reflects idiosyncrasies of the era and exerts children's dignity.

It is not easy to clarify the historical perspective of architect through his architecture. Exceptional cases, it will be the time to design a history museum. As an institution, a Museum already became an apparatus to represent the history to it itself. Libeskind's Jewish museum Berlin has been presented as the controversial case most of all. In particular, in that it instead of dealing with history positive, that contains a tragic history, this building is a building that history a unique interpretation of the architect has been a problem. Therefore, it is difficult to find a suitable example to Libeskind's Jewish museum in Berlin to try and look at the problem of the history of contemporary history and interpretation of the architect. In this paper, I am trying to interpret Libeskind's Jewish Museum Berlin through the aesthetics and history philosophy of Theodor Adorno and Walter Benjamin. They are Jewish and the central figures of the Frankfurt School, known as 'critical theorists'. Their critical theory was formed based on the experience of the Jewish genocide and war.

The choice of individual material for industrial application is primarily based on knowledge of its behavior in similar applications and similar environmental conditions. Contemporary design implies knowledge of material behavior and knowledge in the area of structural analysis supported by large capacity computers. Bearing this in mind, this paper presents and analyzes the experimental results related to the mechanical properties of the material considered (30CrNiMo8/1.6580/AISI 4340) at different temperatures as well as its creep and fatigue behavior. All experimental tests were carried out as uniaxial tests. The test results related to the mechanical properties are presented in the form of engineering stress-strain diagrams. The results related to the creep behavior of the material are shown in the form of creep curves, while the fatigue of the material is shown in the form of stress - life (S - N) diagram. Based on these experimental results, the values of the following properties are determined: ultimate tensile strength (${\sigma}_{m,20}=696MPa$), yield strength (${\sigma}_{0.2,20}=355.5MPa$), modulus of elasticity ($E_{,20}=217GPa$) and fatigue limit (${\sigma}_{f,20,R=-1}=280.4MPa$). Results related to fatigue tests were obtained at room temperature and stress ratio R = -1.
