How the 5G Enabled the COVID-19 Pandemic Prevention and Control: Materiality, Affordance, and (De-)Spatialization.

5G, the most disruptive innovation, had played a significant role in the COVID-19 pandemic prevention and control. However, as a novel technology and context, we have little knowledge about how 5G enabled pandemic prevention and control. This study collected 212 cases and conducted qualitative research to explore how the 5G worked in prevention and control. Based on the concepts of materiality and affordance, we grounded two affordances of spatialization and de-spatialization from the data. Spatialization provides non-contact ways to complete the tasks which are supposed to be completed in contact, and de-spatialization provides remote operations to complete the tasks which are supposed to be completed on-site. Spatialization and de-spatialization enabled the diagnosis and treatment of the infectors to relieve the unbalance of medical staff, cutting the infectious route to contain the viral spread, and logistic supply to support the prevention and control. Our study offers theoretical contributions to digital pandemic prevention and control, and the literature on 5G also offers practical implications.

Effect of Sandplay Therapy on the Mental Health Level of College Students.

To analyze the effect of sandplay (SP) therapy on the mental health level of college students. 500 college students were openly recruited, using the University Student Mental Health Questionnaire (UPI) to screen out 76 students in the UPI category. 34 college students were randomly selected and divided into two groups, 17 in the control group and 17 in the SP therapy group (experimental group); the control group received no treatment, and the experimental group was treated with SP therapy, to analyze the differences between groups before and after the intervention of SCL-90 and self-made group self-reflection questionnaire. (1) With a detection rate of 15.2 percent, 76 of the 500 college students solicited openly were identified as UPI students; (2) except for the terror factor, there were significant differences in other aspects and overall scores for the experimental group following SP therapy intervention, and the scores reduced. There were no significant differences in the total scores and scores of all factors in the control group (P > 0.05). The overall score, somatization, interpersonal connection, depression, paranoia, and psychosis were all significantly different between the experimental and control groups in the independent sample t-test (P < 0.05).
