This study attempted to compare and analyze the commercially available multi-use patterns to develop mask patterns suitable for the face types of adult women. Through this, it was intended to provide necessary data to mask pattern development and products. As a results of comparing the dimensions and shapes of commercial multi-use mask patterns, there was a significant difference in dimensions even though it was a L-size mask manufactured for adults. As a result of the appearance evaluation of the virtual outfit, there were significant differences by design in the vertical of the center front line, the cover and space of the mask, the height of the nose, and the lower part of the mask. The side also showed significant differences in the covering of the side of the face, the space of the side, and the width and length of the string. As a result of the appearance evaluation, Mask 4 received the best evaluation. The shape of the mask pattern had a large dart in the lower part of the nose so that it can cover the three-dimensional shape of the face, but there was a difference in the degree and angle of the curve depending on the mask. Although the upper part of the mask, the lower part of the mask, and the cheek part are in close contact, the evaluation of the mask pattern, which has room in the nose and mouth, was high. It is thought that the mask pattern should be set according to the upper length, lower length, and nose height of the mask through analysis of the face shape and dimensions.

This study is on the general characteristics of 'Monolithic' architecture. The intentions of monolithic architecture can be assumed as an attempt to replace the formal looseness or difficulties of understanding formal complexity of modern architecture, or a trial to react against contemporary avant-garde architectural tendency typically characterized as unstableness, uncertainty, fluidity, and articulation to reestablish autonomy of architecture. Buildings in this category coincide in their extreme economy and simplicity of overall form and consistency of external appearance while showing great expressional capacity with very limited formal means. Even though monolithic architecture still seems a little unstable and ambiguous in historical aspects, it can be considered as strikingly shaped objects or autonomous forms with identities, logics, and representation that promote recognition. Using architectural techniques of scale, colors, materials and finishes, monolithic architecture shows strategically invested surfaces that mediate between the inside and the outside, and shows unexpected and mysterious autonomy. This kind of monolithic approach is also found in interior space as a separate objects that contain functional space inside, or as formal elements that overflow the boundaries of conventional architecture by eliminating the distinction between floor, wall, and ceiling.

Due to the widespread of COVID-19 pandemics, as the health care supplies. Thus the facial mask has been transformed from personal health product into social epidemic prevention product, and its design is more inclined to be User-centered design. First employed health facial mask which is sold in the market as the method subject, under the concept of " User-centered design", this article analyzes the design elements such as appearance and color of the facial mask. Second used the analysis approach of sample, character and positioning map, this article conducts the comparative analysis research of collected sample and data and find the relationship of User-centered design, purchase tendency and health care facial mask. When the users purchase the mask, through the research on the relationship between the choice of form or color of mask and design element of mask, it can compensate for the blank spot of design and has some references.

TEE Forming process for HDPE(High Density PolyEthylen) pipe has been analyzed by using rigid plastic finite element code, DEFORM-3D. TEE of HDPE pipes is necessary to connect main pipe with branch pipe and change the flow direction of hot water. A HDPE pipe is used as a insulator to maintain the temperature of hot water A butt welding process through TEE forming for a HDPE pipe is a updated process improving the strength of welding part compared to conventional extrusion welding process. The Experiment of Hot and Cold Forming have been performed. The design parameters such as a initial hole shape have been obtained through rigid-plastic finite element analysis, which is applied to the actual manufacturing process.

본 연구에서는 사각형태 화장품 케이스 사출성형 시 발생되었던 수지 미성형 불량을 해결하기 위하여 사출성형해석 기술을 통해 성형품 형상변경 및 사출금형 내 유동 시스템 수정방안 도출을 수행하였다. 대상제품인 사각형태 화장품 케이스는 상측부 케이스로서 케이스 외관에 게이트 및 취출흔적이 남지 않아야 함에 따라 측면부 게이트 적용으로 유동거리가 길어져 미성형 불량이 다수 발생하는 제품이다. 따라서, 수지 유동성 향상과 더불어 효율적인 보압전달을 통하여 수지 충전 및 변형발생 저감을 위하여 성형품 형상변화 및 유동시스템 변화에 따른 사출성형해석을 수행하고 결과를 고찰하였다. 이로써 최종적으로 수지 미충전으로 인한 미성형 불량을 제거하고 성형품 변형을 줄일 수 있는 수지유동시스템 수정방안을 제시하였다.

The flow of remote field eddy current energy is studied at nonmagnetic coaxial tubes by using both experiments and finite element calculations based on commercial software package. The results showed that remote field eddy current energy at coaxial tubes flow along over the outer surface of external tube, not through the gap between internal and external tubes. This means that the through wall transmission characteristic of remote field eddy current testing (RFECT) is still valid at tube in tube configurations and the RFECT could be potential nondestructive technique for crack detection, spacer location and gap sizing at the coaxial CANDU fuel channel tubes.

Interests in 3D virtual clothing technology and its application in online shopping malls are increasing with the advent of the Fourth Industrial Revolution. Most studies on 3D virtual clothing, however, are focused on observing drapes or ease of virtual clothing depending on fabric properties of representative clothing items. Therefore, the purpose of this study is: first, to determine if current input of typical material characteristics in 3D CLO are sufficient to formulate virtual skirts with different front and back silhouettes; second, to determine if subjective appearance evaluation matched physical shape characteristics of those skirts. In this study, appearances of typical cotton, wool, silk, rayon, and polyester skirts with different front and back pattern were compared between actual and virtual clothing depending on fabric materials. Subjective appearance evaluation was conducted by 7 experts regarding similarity between actual and virtual clothing with a 5-point scale. For objective evaluation of the both types of skirt shape, degree of roundness at the cross section, displacement of side seam, position of back waistline, and the number of folds at the skirt back were observed. In the case of cotton and wool, not the subjective appearance evaluation as well as shape characteristics of virtual skirts were well matched to the actual shape of skirts with a few material inputs. However, current material inputs for silk, rayon and polyester were insufficient to cover material differences in formation of virtual skirts with different front and back silhouettes.

In the concentric tube type recuperator, which is the most typical type of radiation recuperator, installed on the exhaust-secion of industrial furnace, air flows between the adiabatic outer tube and the inner tube in which exhausted gas flows with high temperature. The waste heat of the exhausted gas is transferred to the inner tube, and transferred from the inner tube to the flowing air. The heat transfer by radiation In the concentric tube type recuperator is modeled using spherical harmonics approximation, namely, P-N method and numerically analyzed considering the effect of dynamic flow field. The results are compared with the existing empirical data. In addition, a theoretical method is presented for the analysis of the heat transfer characteristics of a recuperator with a reradiator installed in the inner tube, which causes re-radiant in the inner tube, and the characteristics of the recuperator is analyszed and defined.
