Research on the Teaching Model of Animation Professional Class Based on AR/VR Technology and 5G Network

The use of emerging technologies is becoming more common in today’s world, and as media integration deepens, so does the use of virtual reality technology. As an emerging science and technology, VR/AR technology plays a critical role in society’s development and progress, and its application in current education and teaching has become an indispensable link. The production of high-quality animation professionals is the society’s and the animation industry’s urgent need for talent, the precondition for the prosperity of cultural and creative industries, and the foundation of national soft power. To bring more technical changes to education and provide theoretical support for the realization of human-computer interaction technology, this paper mainly elaborates on the concept and application fields of VR/AR technology and discusses the specific applications of VR/AR technology according to its different educational stages. The main point of the presentation is to demonstrate how, in the era of 5G networks, large bandwidth, ultralow latency, massive connectivity, and ultrahigh reliability provide a strong network foundation for widespread VR/AR application. We will investigate the paucity of teaching methods, teaching modes, and teaching platforms as a result of the application of 5G-based VR/AR technology in the teaching field of animation majors, as well as the design of teaching methods, teaching modes, and experimental training platforms based on 5G-based VR/AR technology in animation majors in conjunction with the training plan of engineering students at our university. We will delve deeper into the integration of VR/AR technology and higher education teaching, laying the groundwork for “AI+” education. VR/AR technology can be used in the classroom to present information to students in a more three-dimensional and intuitive way, which not only increases student interest in learning but also improves the learning experience and cultivates core literacy.

Teaching and learning approaches practiced by educators today must be different to suit the contents and time. Lecturers-teaching focused on student-centered teaching should be encouraged and emphasized as highly active student involvement is required during the process of teaching and learning. Active student involvement will form the interest of students to explore knowledge. The purpose of this study is to get the students’ perception of the lecturers’ teaching and students’ learning experiences. In this study, the lecturers’ teaching aspect highlighted is composed of a lecturer-centered teaching methods and student-centered teaching and learning experience aspects is in relation to active learning and passive learning. This study involved a total of 169 respondents among 2nd semester engineering students of diploma program who are studying in Engineering Mathematics 2 at Polytechnic Kuching Sarawak. These samples were identifid through stratifid random sampling method to answer a questionnaire about the lecturers’ teaching and students learning experiences. The instrument used was a structured questionnaire which containing 20 items. The data obtained were analyzed using descriptive statistics; i.e. mean, percentage and standard deviation. Through this study, the overall mean value obtained for lecturer-centered teaching methods and student-centered teaching methods are respectively 4.08 and 3.81. While the overall mean for active learning and passive learning is respectively 3.65 and 4.04. In this regard, the role of the lecturers who teach should not be underestimated because the majority of students still consider lecturer as a source of knowledge and “guardian” of them.

Abstract It is known that matrix models computing the partition functions of three-dimensional $$ \mathcal{N} $$ N = 4 superconformal Chern-Simons theories described by circular quiver diagrams can be written as the partition functions of ideal Fermi gases when all the nodes have equal ranks. We extend this approach to rank deformed theories. The resulting matrix models factorize into factors depending only on the relative ranks in addition to the Fermi gas factors. We find that this factorization plays a critical role in showing the equality of the partition functions of dual theories related by the Hanany-Witten transition. Furthermore, we show that the inverses of the density matrices of the ideal Fermi gases can be simplified and regarded as quantum curves as in the case without rank deformations. We also comment on four nodes theories using our results.

Background: Anticancer peptides (ACPs) have received increasing attention as a promising class of novel anticancer agents owing to its potent and rapid cytotoxic properties. In this study, we aim to investigate the effects of cationicity and hydrophobicity in modulating the cytotoxicity of PtxC, a class of ACP from the leafy mistletoe Phoradendron tomentosum against the MDA-MB-231 and Vero cells. Method: We designed a series of four PtxC analogues (PA1 – PA4) by residual substitutions with specific amino acids to introduce the specific charge and hydrophobicity alterations to the analogues. The cytotoxicity strength of the PtxC analogues on MDA-MB-231 and Vero cells were tested by using MTT assay at 24 hours post treatment. Results: PA1, PA2 and PA4 displayed marked increases in cytotoxicity against both MDA-MB-231 and Vero cells and can be ranked in the order of PA2 > PA4 > PA1 > PtxC > PA3. Sequence-activity relationship analyses of the designed analogues showed that an increase in the level of cationicity and hydrophobicity correlated well with the enhanced cytotoxic activity of PtxC analogues. This was observed with PA1 (netC +8) and PA2 (netC +10) in comparison to PtxC (netC +7). Similar finding was observed for PA4 (GRAVY +0.070) in contrast to PtxC (GRAVY -0.339). Three-dimensional modelling predicted a double α-helix structure in PtxC class of ACP. The larger first helix in PA2 and PA4 was suggested to be responsible for the enhanced cytotoxicity observed. Conclusion: The critical role of cationicity and hydrophobicity in enhancing cytotoxicity of PtxC class of ACPs were clearly demonstrated in our study. The current findings could be extrapolated to benefit peptide design strategy in other classes of ACPs toward the discovery of highly potent ACPs against cancer cells as potential novel therapeutic agents.

Purpose: The focus of this retrospective review paper is toexplore and analyse pedagogic research development in physiotherapy education in South Africa.Methods: A content analysis of publications by educators in the SA Journal of Physiotherapy between 1989 and 2003 was conducted to identify and classify the pedagogic articles. Further analysis of physiotherapy education articles was performed to determine the primary foci of the education research, using a three- dimensional pedagogic outcomes research framework.Data analysis: Descriptive statistics in terms of frequencies, means and percentages was used for the analysis. Results: The results revealed that most of the educators’ articles focused on clinical practice. Only 23% of the articles were about education and the majority of those were on clinical education (72%), with few articles on curriculum issues and teaching methods. Conclusion: The research focus of South African Physiotherapy educators is more on the clinical practice, and not on education. The importance of linking research, clinical practice and education cannot be overemphasized, hence the need to develop research in education.

Spatial visualization is the ability of an individual to imagine an object mentally and understand its spatial orientation. There have been multiple works proving that spatial visualization skills can be improved with an appropriate training. Such training warrant a critical place in the undergraduate engineering curricula in many engineering schools as spatial skills are considered vital for students’ success in the technical and design fields [1–4]. Enhanced spatial skills help not only professionals in the engineering field but also everyone in the 21st century environment. Drawing sectional views requires mental manipulation and visual thinking. To enhance students spatial reasoning, one of the authors of this study, conducted a class in spatial visualization. The course-learning goal aimed at improving first-year engineering students’ spatial reasoning through instruction on freehand drawings of sectional view. During the semester, two teaching assistants had to grade more than 500 assignments that consisted of sectional views of mechanical objects. This was a tedious and a time consuming task. Motivated by this experience, this paper proposes a software aiming at automating grading of students’ sectional view drawings. The proposed software will also give live feedback to students while they are working on the drawings. This interactive tool aims to 1) improve the learning experience of first year students, with limited CAD knowledge, and 2) introduce a pedagogical tool that can enhance spatial visualization training.

Tankyrase 1

Telomere repeat factor 1 (TRF1) is a subunit of shelterin (also known as the telosome) and plays a critical role in inhibiting telomere elongation by telomerase. Tankyrase 1 (TNKS1) is a poly(ADP-ribose) polymerase that regulates the activity of TRF1 through poly(ADP-ribosyl)ation (PARylation). PARylation of TRF1 by TNKS1 leads to the release of TRF1 from telomeres and allows telomerase to access telomeres. The interaction between TRF1 and TNKS1 is thus important for telomere stability and the mitotic cell cycle. Here, the crystal structure of a complex between the N-terminal acidic domain of TRF1 (residues 1–55) and a fragment of TNKS1 covering the second and third ankyrin-repeat clusters (ARC2-3) is presented at 2.2 Å resolution. The TNKS1–TRF1 complex crystals were optimized using an `oriented rescreening' strategy, in which the initial crystallization condition was used as a guide for a second round of large-scale sparse-matrix screening. This crystallographic and biochemical analysis provides a better understanding of the TRF1–TNKS1 interaction and the three-dimensional structure of the ankyrin-repeat domain of TNKS.

Based Instruction

With its ability to afford immersive and interactive learning experiences, virtual reality has been widely used to support experiential learning, of which the learning effectiveness is promoted by the instructional component of debriefing. The current literature on debriefing mainly focuses on the traditional learning contexts while little is known on its effectiveness in immersive virtual reality (IVR) learning environments. Based on the theories of experiential learning and debriefing, this study designed a debriefing strategy based on simulated learning experience and investigated its effectiveness on knowledge and behavioral learning in an IVR learning program, using a randomized controlled trial with 77 elementary students from Hubei province in China. The study results support the efficacy of IVR on improving knowledge acquisition and behavioral performance, and reveal a significant moderating effect of debriefing on the effectiveness of IVR learning environments. The study confirms the critical role of debriefing in IVR-based instruction and provides theoretical and practical implications for the design and implementation of effective IVR learning environments.

Previous studies have revealed that when video gamers, or users of three-dimensional (3D) virtual worlds, display intense concentration coupled with an emotional engagement in their undertaking, they are affected by multisensory stimuli. This can lead to developing a feeling of detachment from the physical world, which, in turn, can lead to high levels of participation and engagement. Notwithstanding these results, it remains unclear as to whether students can experience the same kind of immersion in two-dimensional (2D) platform-based online collaborative learning spaces as has been achieved in video games and 3D worlds and, if they actually can, which features would lead to similar levels of increased engagement. This study is one of the first attempts to investigate the immersion experiences of students engaged in two 2D online collaborative learning platforms, one text-based and the other video-based. Data from eight students revealed that key features of immersion observed in video games and 3D worlds also appeared during the online collaborative activities but that the way such immersion was perceived by the students was greatly affected by the characteristics of the individual platform. When emotional engagement was considered, empathy was found to play an important role in the participants’ immersion experiences. Implications for practice or policy: Text-based platforms could be effective in motivating students to focus more on the postings, while video-based platforms may be more effective in generating empathy with others through observation of body language. When selecting a communication platform for online collaboration, sensory stimuli of the platform should be carefully examined. Empathy could be developed prior to an online collaborative activity so that students reflect on their thoughts and consider others’ feelings for a more immersive learning experience.

Abstract. In Coupled Groundwater and Surface-Water Flow (GSFLOW) model, the three-dimensional finite-difference groundwater model (MODFLOW) plays a critical role of groundwater flow simulation, together with which the Precipitation-Runoff Modeling System (PRMS) simulates the surface hydrologic processes. While the model development of each individual PRMS and MODFLOW model requires tremendous time and efforts, further integration development of these two models exerts additional concerns and issues due to different simulation realm, data communication, and computation algorithms. To address these concerns and issues in GSFLOW, the present paper proposes a conceptual framework from perspectives of: Model Conceptualization, Data Linkages and Transference, Model Calibration, and Sensitivity Analysis. As a demonstration, a MODFLOW groundwater flow system was developed and coupled with the PRMS model in the Lehman Creek watershed, eastern Nevada, resulting in a smooth and efficient integration as the hydrogeologic features were well captured and represented. The proposed conceptual integration framework with techniques and concerns identified substantially improves GSFLOW model development efficiency and help better model result interpretations. This may also find applications in other integrated hydrologic modelings.
