최근의 급변하는 다원적이고 복합적인 문화의 흐름은 새로운 양식으로의 변화를 추구해 왔으며 기존의 조형예술의 개념, 가치 등에 대한 변모와 영역의 확장이 동반되고 있다. 이는 예술세계가 끊임없는 아이디어로 인간의 무한한 창조의지를 다양한 미적 의지로 보여지는 것을 가능하게 하였다. 이러한 다양화의 시도는 예술의 영역의 확대를 낳게 되었고, 패션도 현대예술 전반에서 일어나고 있는 소재나 기법을 공유하는 다양한 조형적 표현방법이 결합되어 영역의 확대와 소재의 한계를 벗어나게 되었다. (중략)

Non-photorealistic Rendering(NPR) is a method that can be used to simulate a wide range of materials used in visual arts. Currently, there is lack of availability for oriental-style rendering in 3D animation in contrast to the commonly available western-style rendering. In this paper, we combine the wash drawing technique and NPR to create an oriental-style shader for 3D animation. Our approach makes use of the Maya Embeded Language(MEL) to implement this new technique.

Nanomaterial electrodes are used to improve the analytical performances of electrochemical measurements in biological and chemical field. Frequently used methods for fabricating metal nanostructures are solution processing and electrodeposition. In the solution process, it is possible to control the characteristics (e.g., direction) of metal growth by using capping agents, thereby fabricating nanoparticles of specific structures. In the electrodeposition, the electrode surface and the deposited metal atoms are in direct contact. Each process has its own limitation as well, and many studies are conducted to overcome such limitation. In this paper, we report an integration of the two fabrication methods and the characteristics, such as structural and electrochemical properties, of the fabricated electrodes. Lastly, we discuss the possibility of using the fabricated nanostructured electrode as a sensor.

In the development and mass production of polymers, there are many uncontrollable variables. Even small changes in chemical composition, structure, and processing conditions can lead to large variations in properties. Therefore, Traditional linear modeling techniques that assume a general environment often produce significant errors when applied to field data. In this study, we propose a new modeling method (GPR-SEM) that combines Structural Equation Modeling (SEM) and Gaussian Process Regression (GPR) to study the Friction-Coefficient and Flexural-Strength properties of Polyacetal resin, an engineering plastic, in order to meet the recent trend of using plastics in industrial drive components. And we also consider the possibility of using it for materials modeling with nonlinearity.

에듀테인먼트는 교육(education)과 오락(entertainment)의 합성어이다. 교육적인 내용을 놀이와 접목시킨 것을 말한다. 최근 하천개발은 치수적인 면에 개발과정을 넘어서 친수적인 면, 환경적인 면을 부각시켜 보다 질높은 삶을 살아가는 방향으로 발전하고 있다. 치수사업에 있어서도 과거의 제방중심의 사업에서 보다 다양하고 진보된 대책의 개발과 적용이 이루어지고 있다. 이러한 치수적인 안정을 기반으로 친수적인 면이 부각되면서 보다 접근성이 용이하고, 친수적인 하천의 개발이 지속적으로 이루어지고 있다. 최근의 지역축제로 성공적인 하천 축제로 강원도 양양군 연어축제(남대천), 경상북도 봉화은어축제(내성천)등이 있다. 이러한 축제들은 주요내용이 물고기를 잡는 체험과 관계기관의 적극적인 참여와 관리로 전국의 관광객들이 찾는 축제로 발전하고 있다. 일반적으로 이러한 축제들은 대상어종에 대해 설명하고 있으며, 물고기를 잡는 체험으로 진행되고 하천에 대한 스토리를 접목시키지만, 하천변 개발로 이루어지는 것은 부족한 실정이다. 본 연구에서는 하천개발에 있어 다양한 소재를 접목시켜 친수적 하천개발에 교육적 요소를 결합하여 스토리 텔링기법으로 하천을 개발하는 방안을 제안하였다.

In this study, the adhesion properties between aluminum and composite materials, composite materials, and composite materials were compared according to the physical surface treatment to improve mechanical bonding at the bonding surface when considering carbon fiber and glass fiber-reinforced composite materials. Bonded specimens were classified into the type of base material and the surface treatment method of the bonding surface. Sandpaper, sandblasting, and plasma were applied as physical surface treatment methods. The bonded specimen was prepared as a single lap joint test specimen. An experiment to measure the lap shear strength was conducted, and the results were compared. The experimental results confirmed that the mechanical abrasion and sandblasting treatment improved the lap shear strength approximately 4 to 5 fold compared to the general specimen without physical surface treatment. In plasma treatment, the experiment was conducted by defining the respective plasma output and treatment time as follows: 150 W and 5 minutes, 150 W and 10 minutes, and 300 W and 3 minutes. Moreover, the lap shear strength results were similar to the previous mechanical surface treatments. On the other hand, the effect on the adhesion properties was small, depending on the plasma treatment conditions.

In making gardens, garden designers establish a principle using specific colors, collect materials, and combine them with their own aesthetic senses. This study is design mothed through the species and characteristics of flowering plants used in the Barrington court created by Gertrude Jekyll and Sissinghurst's white garden created by Vita Sackville-West, both of which are the most renowned gardens that used the white color. The analysis of each individual plant used in the gardens will be based on the season, colors, shapes, plant heights and aromaticity. Through their gardens, how the flowering plants aesthetically united with each other in creating the white gardens will be reviewed. To represent the freshness of spring, Jekyll planted Campanula spp. and Lilium spp. in the garden. Vita Sackvill-West aims at the moonlight in a summer night and features Delphinium spp., Rosa mulliganii, and R. longicuspis. The color of the flowers is in white, varying from pure white, ivory and silver. To prevent monotony due to monocolor flowers, the forms of the flowers are intense. To make white flowers look better, the colors of leaves include light green, light gray and bright and greenish yellow. Overall, cool colors are used to give a mystique, coolness, cleanness and to produce an fascinating and plaintive atmosphere, getting joined with white flowers and reflected light in the night. The White Garden has made significance in the history of landscape architecture: it was the starting point of garden design through theme colors, based on the idea and technology of planting design methods that discover the potential of colors and withdraw limits. And it also made a significant contribution to the advancement of garden art with combinations by aesthetic principles.

Today, the expansion of the possibility of new expressions of plastic arts is largely due to emergence and application of new materials. In the field of flower design, it is found that there is a tendency to seek a new expression by utilizing various new materials instead of natural material that used in the past. This study is an attempt of applying methodological approach in the creation of floral art works utilizing the characteristics of contemporary materials in such context. The researcher gathered cases of specific effect and sensation in the expression of art works using various contemporary materials and extracted the characteristics using descriptive sentences applying behavior setting analysis technique. Reporting detailed result of the research total 100 guidelines under 41 sub-categories, 24 mid-categories, and 6 top categories such as transparency, lighting, combination of objects, combination of materials, reflection, shape construction. The researcher tested the effectiveness of the theories by applying deducted theories as the guidelines in creation process of her own floral art works. The significance of this study lies at experimenting the possibilities of applying methodological approach which could supplement intuitive approach in pursuit of expression for artists in the field of floral art and design.

The existence of different thermodynamic properties results in various undesirable effects, such as thermal deformation and residual stress, in heat-welding processes. The solid-state junction, by using explosive or electromagnetic forces, i.e., high-velocity impact welding without employing heat is advantageous in joining materials with different thermodynamic properties. In the solid-state junction, the joining is performed within a short time, a high velocity and large deformations are accompanied by interfacial surfaces. The numerical analysis models play an important role in the understanding of the mechanism of high-velocity impact welding. However, in the analysis of high velocity and large deformations, the conventional Lagrangian method has low reliability due to the occurrence of entanglements. In this study, high-velocity impact welding between Cu and CP-Ti with different thermodynamic properties was performed using a un-gridded numerical method, SPH (Smoothed Particle Hydrodynamics), and interfacial morphology occurred. As a result of the analysis, the interfacial morphology was confirmed and the compared degree of shape (straight, vortex), period, length, and so on appeared differently depending on the relationship between the parameters (impact angle and speed).
