Both teachers and learners should participate in non-face-to-face class due to COVID-19. The non-face-to-face class has brought about many problems, where they made adequate preparations for such abrupt situation. This study attempted to understand and improve problems occurring during non-face-to-face midi class. The findings are as follows: First, there were differences in equipment available to contact and non-face-to-face class. Such a problem could be improved by using Reaper, DAW which can be installed and freely utilized without any functional limits, regardless of the types of operating systems. Second, latency could not be reduced, when the screen share function of Zoom was used, since it was impossible to select audio interface's drivers in DAW. This problem was improved by again receiving audio output as input and sending it, from the perspectives of teachers. In addition, learners who used the operating system of Windows and have no audio interfaces usually suffer from latency during practices. The latency can be reduced by installing Asio4all. Third, image degradation and screen disconnection phenomena occurred due to the lack of resource. Two computers were connected by using a capture board and the screen disconnection phenomena could be improved by distributing resources and maintaining high-resolution. The system for allowing non-face-to-face midi class could be successfully established, as one more computer was connected by using Vienna Ensemble Pro and more plug-ins were used by securing additional resources. Consequently, the problems of non-face-to-face midi class could be understood and improved.

Japan's mechanic animation is widely known throughout the world. 1952년, Japan's first mechanic animation and the first TV animation, , has been popular since it's creation in 1952. Atom, a big hit at the time, has influenced many people. Japanese mechanic animations convey their unique traits and world view to the public In this paper, we are going to discuss the change of the Japanese mechanical design through comparison of the mechanical design, which has been booming since the 1990s in Japan; and the . I expect the results of this analysis to depict Japanese culture and thought reflected in animation, which is a good indication of worldwide cultural view of animation. unexpectedly influenced the Japanese animation industry after it screened in 1995, and there are still people constantly reinterpreting and analyzing it. This is the reaction of the audience to anticipate the mystery and endless conclusions of the work itself. The design elements of Evangelion are distinguished from other mechanical objects. Mechanic design based on human biotechnology can overcome limitations of machine and make you feel more human. The pilot 's boarding structure, which can contain human nature, is reinforced in the form of an enterprising plug, and the attitude of excavation makes humanity more prominent than a straight robot. Thus, pursues a mechanic design that can reflect human identity. can be selected as the mechanic animation of the 80's, and the "Neon Genesis Evangelion" of the 90's shows it with a completely different design. By comparing the mechanical design of two works, therefore, we examine the correlation between the message and the design of the work. presents the close relationship between the identity of the mechanical design and the contents. I would like to point out that mechanical design can be a good example and theoretical basis for the future.

This study was conducted to evaluate the growth characteristics of lettuce (Lactuca sativa L.) as affected by artificial light sources and different growing media in a closed-type plant production system (CPPS). The lettuce seeds were sown in the 128-cell plug tray filled with 5 different growing media such as urethane sponge (US), rock-wool (RW), Q-plug (QP), TP-S2 (TP) and PU-7B (PU). The germination rate of lettuce seeds was examined during 12 days after sowing. On the 13 days after sowing, the lettuce seedlings were transplanted in a CPPS with temperature $25{\pm}1^{\circ}C$ and nutrient solution (EC $2.0dS{\cdot}m^{-1}$, pH 6.5) using recirculating deep floating technique system. The light sources were set with FL (fluorescent lamps) and combined RB LEDs (red : blue = 7 : 3) with $150{\pm}10{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD and a photoperiod of 14/10 hours (light/dark). The initial germination rate of lettuce was the highest in TP. The final germination and mean daily germination were the significantly highest in RW, QP and TP. The plant height, leaf length, leaf width, leaf area, and fresh and dry weights of shoot were the greatest in QP irradiated with RB LED. The number of leaves, fresh and dry weights of root and SPAD were the greatest in QP and TP irradiated with RB LED. The root length was the longest in TP irradiated with RB LED. Therefore, these results indicate that RB LED was effective for the growth of lettuce and it was also found that the QP and TP were effective for the germination and growth of lettuce in a CPPS. In addition, we confirmed the applicability of the newly developed growing medium TP for the lettuce production in a CPPS.
