As modern people's living standards improved and conscious growth took place, the number of households raising pets increased as the companion animal culture spread. However, due to the difficulties of raising animals, there were many households that could not raise them responsibly to the end, which led to an increase in abandoned animals. This paper aims to develop interactive content consisting of three stages of programs to promote adoption of abandoned dogs and improve negative social awareness of abandoned dogs. The first program is a quiz program using a smart pad that informs the status and information of abandoned dogs. The second program is a 2D jump game using a dog figure and a PC, which informs users of what they need to raise animals and adopts a virtual dog. The third program is a program using HoloLens 2, which interacts with virtual dogs augmented in reality. While experiencing extended reality content, users can clearly recognize the problem of abandoned dogs, the situation they are in, and the adoption of abandoned dogs, know about the necessary items and mindset when raising an animal, and feel a bond with animals virtually. 현대인들의 생활 수준이 향상되고 의식적인 성장이 이루어짐에 따라 반려동물 문화가 확산하면서 반려동물을 키우는 가구가 증가하였다. 하지만 동물 양육의 어려움에 책임감 있게 끝까지 키우지 못하는 가구가 많아졌고 이는 유기동물의 증가로 이어지게 되었다. 본 논문에서는 3단계의 프로그램으로 구성된 인터랙티브 콘텐츠를 개발해 유기견 입양에 대해 홍보하고, 유기견에 대해 부정적인 사회적 인식을 개선하려고 한다. 첫 번째는 스마트 패드를 활용한 퀴즈 프로그램으로 유기견에 대한 실태와 정보를 알려준다. 두 번째는 강아지 모형과 PC를 활용한 2D 점프게임으로, 동물을 키우는 데 필요한 것들을 알려주고 가상의 강아지를 입양한다. 세 번째는 홀로렌즈2를 활용한 프로그램으로, 현실에 증강된 가상의 강아지와 상호작용한다. 확장현실 콘텐츠를 체험하면서 유기견 발생에 대한 문제와 유기견이 처한 상황 그리고 유기견 입양에 대해 확실히 인지하고, 동물을 키우게 되면 필요한 물건과 마음가짐에 대해 알고 가상에서 동물과 유대감을 느껴볼 수 있다.

Nano-stereolithography, also known as two-photon direct writing is widely used for fabrication of the three-dimensional microstructure with submicron resolution. Heirarchical three-dimensional meshed microstructures are crucial for microelectromechanical systems (MEMS), photonics and biotechnological applications. Routine study for various applications using such structures requires fabrication of many sets of structures. Conventionally such meshed microstructures are constructed through layer-by-layer accumulation with discrete point-to-point laser scanning. This technique is time consuming, leading to long fabrication times placing constraints on practical applications as well as optimization of structures. In this work we propose continuous longitudinal laser scanning method as an effective means for direct writing of hierarchical three-dimensional meshed microstructures. The advantages of continuously longitudinal laser scanning method are explored for its time economy and fabrication effectiveness; a fabrication window is suggested to determine the fabrication parameter easily according to laser power and structural design.

This paper describes training data construction and analysis for developing a process-optimized artificial intelligence model to minimize errors occurring during the SLA-based additive manufacturing process. The photocurable resin molding method is a way in which UV lasers are irradiated into a tank containing liquid resin, solidified and stacked layer by layer, and like other additive manufacturing methods, there is an error in output deformation. However, due to the opaque resin, it is more difficult to check the error pattern than other method printer. In this study, to detect these error patterns, collecting data system in the actual process was established for sensor data, image data, and thermal image data and a study on data analysis was conducted

Recently, due to high theoretical capacitance and excellent ion diffusion rate caused by the 2D layered crystal structure, transition metal hydroxides (TMHs) have generated considerable attention as active materials in supercapacitors (or electrochemical capacitors). However, TMHs should be designed using morphological or structural modification if they are to be used as active materials in supercapacitors, because they have insulation properties that induce low charge transfer rate. This study aims to modify the morphological structure for high cycling stability and fast charge storage kinetics of TMHs through the use of nickel cobalt hydroxide [NiCo(OH)2] decorated on nickel foam. Among the samples used, needle-like NiCo(OH)2 decorated on nickel foam offers a high specific capacitance (1110.9 F/g at current density of 0.5 A/g) with good rate capability (1110.9 - 746.7 F/g at current densities of 0.5 - 10.0 A/g). Moreover, at a high current density (10.0 A/g), a remarkable capacitance (713.8 F/g) and capacitance retention of 95.6% after 5000 cycles are noted. These results are attributed to high charge storage sites of needle-like NiCo(OH)2 and uniformly grown NiCo(OH)2 on nickel foam surface.
