Projection Mapping of Illustration Design in the New Media: A Focus on the Bathroom
Yanqi Yin,Junghyen Kim,Surng Gahb Jahng 중앙대학교 영상콘텐츠융합연구소 2021 TechArt :Journal of Arts and Imaging Science Vol.8 No.2
As a type of traditional painting, illustration has a long history of development. The medium of illustration is constantly changing with the improvements in social science and technology. Illustrations, in the context of the new media, have ventured beyond the constraints of paper media, merged with new media technology, and appeared in the public's vision through diverse display methods. This study takes the work <Bathroom> as an experiment, and will introduce its production process and display content in detail. Through the production results summarizes the unique application of projection mapping technology in the illustration design by combining both to provide the audience with a new visual experience.
High catalytic performance of CuO nanocrystals with largest defects

To improve the calalytic performance of CuO, nanometer-sized CuO particles were prepared with ultrafiltration surface contact method (UMSCM). X-ray powder diffraction (XRD) and scanning electron microscopy (SEM)were used to characterize the crystal structure and morphology of the particles made with UMSCM, hydrothermal method,grounding method as well as a commercial one. SEM results illustrate that UMSCM prepared CuO particles mainly show the form of orthorhombic sliced crystals with the largest amounts of defects compared to CuO particles made by the other three methods. In the oxidation of cumene, CuO prepared with UMSCM also shows better catalytic performance than the other three particles, which can be ascribed to its smaller particle sizes and larger defects so as to accelerate the surface adsorption rate of O_2 molecules and the diffusion of ions and atoms, thus improving the catalytic activity.

The radiation environment in space poses signicant challenges to human health, and it is a ma- jor concern in long duration, manned space missions. Outside Earth's protective magnetosphere, astronauts are exposed to higher levels of galactic cosmic rays (GCRs), whose physical character- istics are distinct from those of terrestrial sources of radiation, such as X-rays and gamma-rays. GCRs include high-energy heavy ions, many of which have ranges that exceed the depth of shielding and can be launched in realistic scenarios. Protecting the astronauts from these particles has been a key issue in manned space missions. Therefore, a need exists for reliable simulations of these harmful effects for risk assessment and shielding optimization in manned space missions. The aim of this work was to investigate shielding materials that can be used in deep space and planetary exploration. In this work, we used the Geant4 radiation transport code, originally developed by the International Geant4 Collaboration, and we compared the radiation shielding effectivenesses of polyethylene, aluminum, water, and carbon ber targets hit by 1GeV/nucleon 56Fe (considered as a representative of high-energy GCR). In addition, the total absorbed doses at the water phantom behind these targets were calculated using the Geant4 simulation code. The calculated results were analyzed, compared, and discussed. The results show that polyethylene is the best space radiation shielding material for a given areal density, followed by water, carbon ber, and then aluminum.
