Introduction The current teaching mode of table tennis in China is satisfactory, but there are still some problems that are the focus of physical education teachers, such as the low efficiency of sports training. Objective Study the effect of abdominal core training on table tennis teaching. Methods Volunteers trained in table tennis at a physical education college were divided into the experimental and control group. Before and after the beginning of the experiment, table tennis students’ physical indices and overall physical scores were obtained under a parameterized protocol. Results The overall score of the experimental group resulted from 7.355 (± 1.827) to 9.072 (± 1.992) before training, and the mean difference was 1.2581 points (P < 0.05), indicating a significant difference. The control group score increased from 7.606 (± 1.937) to 7.989 (± 1.440) before training, and the mean difference was 0.1976, P > 0.05, indicating no significant difference. Conclusion Compared with the current way of teaching table tennis, the scheme proposed in this paper showed better sports efficiency and could help students to improve their physical quality and sports ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

The thoughts and practices for educating the new generation of Chinese designers to meet sustained growth and inclusive development in China is the focus of this paper. Three institutes at Tsinghua University in China co-established the interdisciplinary master’s program, Information Art and Design, in 2009. We created a new research framework for this program to identify the opportunities of social and business innovation, integrate the methodologies based on design thinking, and frame the multi-entrance educational model. The exploration, thoughts and lessons on team building, project management, knowledge construction and integrated innovation will hopefully be a good reference for building similar programs.

Under the exponential growth of the computing power of artificial intelligence, the revolution of thinking that designers pursue turn to qualitative rather than quantitative. Instead of trying to capture as many signals as possible, it's judging and internalizing the signals. Design and art practitioners are widely considered to be the most divergent thinkers, and the early stages of design thinking include a variety of heuristic tools to guide users through brainstorming and propose as many solutions as possible in a short period. We analyzed the research of creativity generation on designers, restored and summarized their commonalities upward, and established the basic format of design signals. Based on this, we explored how to inspire designers to pull out from the rigid thinking system, to discover more unknown connotations, more perspectives, and possibilities for understanding. This paper attempts to promote a path of inspiration to explore the desirable future. By exploring and analyzing the path of designers to generate design inspiration, we propose the Prototype Inspiration tool of the future footprint and start from three dimensions of future signals, values, and personal experience. Inspire the design team to generate a quality conception of the future based on the separation, integration, and reorganization of real signals in a short time. And introduce the prototype inspiration tool with future thinking through the application and verification in the real teaching environment, which expands the dimension and depth of design ideas in the early stage of design. We inclined to think future ideas not as being created out of thin air but as being stimulated, as breaking down stereotypes by reconstructing vague, scattered information. This requires developing sensitivity to information and an accurate sense of trends. The prototype heuristic is a preliminary solution proposed by us at the present stage. In the following sections, we will apply the prototype heuristic to a more specific design context to test the effective range of the tool and discuss how the interactive effects and heuristic effects change when multiple people use AR tools remotely. We have several directions for our future work. One direction is to recognize the impact of our proposed prototype heuristic tools on the design concept in new or existing tools, and to examine the impact of creative output on the overall design process. Second, we will further quantify the designer's propensity and familiarity with the various signals, and how they use affects design activities. Third, try to bring both the input of creative inspiration and the output of creative ideas into the prototype inspiration system, that is, to realize the whole thinking process in AR. Fourth, build a community and an open platform for future resources to support online and offline collaboration among team members from multiple backgrounds.

Smart cities functions have been represented in the form of a metaphorical mandala co-opted to serve as an abstract simplification for the public to understand the complexities of smart cities, as well as to compartmentalize the principal functions as discrete facets of the operating system architecture. These six smart functions - Mobility, Environment, People, Governance, Economy and Living - serve their own purpose within the urban framework while simultaneously supporting the collective operations of the city, and over time will develop new typologies and sub-functions as dynamic, transforming systems. In order to explore these functions as part of the evolutionary development of cities, the Multi-Level Perspective model (MLP) has been applied to map diverse urban scenarios as they transition in terms of past (Evolution), present (Challenges) and future (Directions). Since each city's progression is determined by its unique city DNA profile, each smart city function is modeled by describing and visualizing this progression. In parallel, to support the theory and application of convergence, the inter-relationship of human, technological and natural systems is explored along the dimensions of Object, Action and Outcome to articulate the key variables that influence the trajectory of each smart city's distinct technological evolution and transformation.

The paper presents a visualization prototype that tackles the issue of public emotion. It emphasizes the exploration process in the aim of creating reflections for the viewer to observe the whole social context as well as individual perspectives. Urban traffic conversation on SNS (Social Networking Site) is our current interest. The prototype we present is made on real post streams captured from Chinese most popular microblog Sina Weibo. After experimenting on two online prototypes we determine a visualizing flow to lead the viewer going through the insights from macro to micro view in three interaction frameworks: City Sentiment, Related Topics, and Post Content. Through showing the visualizing flow with interaction mode, data analysis, and prototype construction, the paper ends with discussing about design considerations in creating reflections on public traffic emotion in visualization prototype.
