The study investigated trends in wall-covering displays in interior design stores. Although studies reported design trends at well-known exhibitions overseas such as Heimtextil and Maison objet, many different cases present actual realistic design flows. This study analyzes the actual market flow rather than design as an exhibition concept, and presents the interior CMF trends in 2019. The CMF design of wall-covering displayed in New York D&D Building in 2019 can be summarized as follows: W was the most frequently seen show-window, but like R, which is a strong color, it is also used to convey surrealistic images. The store entrance was designed to attract consumers' attention inside, and was constructed to reflect the actual trend. In the 2019 New York market, the wall-covering of Gray and YR were displayed through the shop entrance to suggest substantial sales. In addition, the demand for gold metallic wall-covering is significant as gold was strong in many forms. This study represents a valuable resource to identify trends in wall-covering from 2017 to 2019 compared with previous studies. This study represents a valuable foundation for a wide range of topics related to the use of wall-covering for interior decoration.

Recently, the fashion industry has been integrating with The IT industry in order to develop in various ways. This study looks into ways to utilize the 3D CAD system, which would reduce time and cost while producing samples, and strengthen the communication between the brand and its cooperators by deploying knit designs using Knit CAD system's 3D virtual clothing program. The research method was reference, Internet resources 3D fashion CAD system and 3D Knit CAD system. Based on the data, simulation of the complete design of 4 deployed knit designs was done by using 3D virtual clothing program of the Knit CAD system utilizing knit design elements. One of each design element among the virtual clothing designs was chosen to produce real clothing, and the experts did verification on the appearance assessment of 3D virtual clothing knit designs of the Knit CAD system. As a result, 3D virtual clothing knit design of the Knit CAD system proved itself as an efficient system in terms of time and cost.

마이크로스트립 인터디지털(interdigtal) 여파기는 공진기의 폭, 길이, 공진기 사이의 간격과 탭의 위치로 설계하는데, 설계파라미터의 수를 줄이는 것이 구현 측면에서 유리하다. 본 논문에서는 마이크로스트립 인터디지털 여파기의 설계파라미터 중에서 공진기의 폭을 고정시킨 것과 서로 다른 폭을 갖는 두 종류의 여파기를 국내 UWB(Ultra Wide-Band) 주파수 대역에서 설계 및 구현하였다. 여파기의 성능 측정 결과 공진기의 폭을 고정한 low-band high 여파기의 삽입손실은 1.49dB, -10dB 대역폭은 750MHz였고, 4.8GHz에서 -35.7dB의 감쇄특성을 가졌으며, S11은 -13dB 이하로 측정되었다. 공진기의 폭이 서로 다른 low-band 여파기는 삽입손실 1.6dB, -10dB 대역폭은1.63GHz로 측정되었고, S11은 -8dB 이하로 측정되었다.

Even though 3D press die design gains more attention everyday in Korea, there are shortages of infrastructure and proper environments for it. What is most needed is human resources development and 3D die design standardization, on which the pace of 3D die design adoption depends. This study focuses on 3D press die design process by looking into an instance in which 3D die design system had been used to sell dies to a company "S" in Japan.

This study develops an optimal two-dimensional (2D) pattern from three-dimensional human scan data by considering the cycling posture and dermatome of high school male cyclists. By analyzing the body surface change in the cycling posture and considering the dermatome of the lower limbs, the optimal cutting line setting and the development of cycling tights for individual cyclists were presented to provide data that could be used in the clothing industry. We designed three cycling tights to solve the size unsuitability. 3D design 1 is a non-extension design based on the analysis of the 3D human body scan data, in which parts were connected diagonally from the front of the knee to the back of the knee. 3D design 2 removed both the front and back to reduce air resistance during cycling. 3D design 3 did not have a cutting line on the front panel because of the air resistance during cycling in the front area. We analyzed the garment pressure for 8 points of lower body and performed a subjective evaluation of the 3D designed tights and the current cycling tights. The 3D design 1 in this study was well received in the omphalion, thigh, and hip area, while 3D design 3 was well received in the omphalion, thigh, hip, and bottom bands. Therefore, the LoNE of 3D design 1 was applied to the front, and the hip cutting line of 3D design 3 was applied to the back.

Two-dimensional (2-D) digital filters are widely useful inn image processing and other 2-D digital signal processing fields, but designing 2-D filters is much more difficult than designing one-dimensional (1-D) ones. This paper provides a new insight into the existing singular value decomposition (SVD)-based design approach in the sense that the SVD-based design can be performed more efficiently by exploiting the symmetries of the given 2-D magnitude specifications. By using the specification symmetries. only half of the 1-D filters (sub-filters) need to be designed. which significantly simplifies the design process and reduces the computer storage required for 1-D sub-filter coefficients. Another novel point of this paper si that an objective criterion is proposed for selecting appropriate sub-filter orders in order to reduce the hardware implementation cost. A design example is given to illustrate the effectiveness of the SVD-based design approach by exploiting specification symmetry and new order-selecting criterion.

This paper presents a new structure for the universal motor using soft magnetic composite (SMC). The stator for this new type of motor is made by combination of the SMC pole and the silicon steel yoke. The shape of the 3D SMC pole is designed to minimize ohmic loss and amount of stator coil. To design the pole shape, the 3D analysis in the design procedure is replaced with an equivalent 2D analysis. Finally, the optimal shape is analyzed by 3D FEM and the performance is discussed.

This study aims to develop a hanbok design method in response to recent changes in consumption trends that emphasize new aesthetic and cultural values, which contrast with the existing cultural order and repetitive normative styles in fashion designing. With this in mind, our study explores the main features of deconstruction fashion design as a theoretical guide for developing a methodology for deconstruction hanbok design, on the basis of which new, experimental and creative hanbok design works can be produced. To do this, we first investigate current trends in hanbok design and changing concepts of Korean fashion design through literature review of previous studies. Secondly, we explore deconstructionism and analyze its features to lay down the foundation for a post-modern approach in hanbok design. As the result of analysis, the main features of deconstruction fashion design are summarized as the following: 1) non-finishing, 2) decomposing and recomposing, 3) recycling, 4) transparent, 5) grunge, 6) flattening, and 7) exaggeration. Based on the identified core features of deconstruction fashion design, we develop a creative method of hanbok design in the context of modern Korean fashion design. Finally, we show five design outputs via a 3D digital fashion design process using the CLO3D software program.

3D printing is a technology that converts a computer-generated 3D model into a real object with additive manufacturing technology. A majority of 3D printing technologies uses one material, and this is considered a limitation. In this study, we developed a multi-material 3D printer by adopting dual resin vat and cleaning system with DLP (Digital Light Processing) 3D printing technology. The developed multi-material DLP 3D printer is composed of a manufacturing system, cleaning system, transporting system, and automatic resin recharging system. Various 3D structures were 3D printed with two materials, thus demonstrating the potential. Printing performance of the multi-material DLP 3D printer was studied by performing a comparative surface roughness test and tension test on specimens composed of one material as well as those composed of two materials.
