On the Strategies of Strengthening the Construction of Campus Culture in Colleges and Universities from the Perspective of the New Era

At present, our country has entered a new stage of development. In the context of rapid economic development, people have increasingly realized the importance of cultural construction to social development. As a base for training talents, colleges and universities must fully realize the importance of school culture construction, and combine their own advantages and characteristics to explore effective ways of campus culture construction. Colleges and universities should guide students to establish a correct outlook on life and values, strengthen students’ ideological and moral education, promote the construction of a harmonious campus, and promote the connotative development of the school. This article first analyzes the significance of the construction of campus culture in colleges and universities in the new era, and discusses the strategy of constructing campus culture in colleges and universities, hoping to provide some reference for the comprehensive development of college campus culture construction.

Benefits of integrated screening and vaccination for infection control

Importance. Screening and vaccination are essential in the fight against infectious diseases, but need to be integrated and customized based on community and disease characteristics. Objective. To develop effective screening and vaccination strategies, customized for a college campus, to reduce COVID-19 infections, hospitalizations, deaths, and peak hospitalizations. Design, Setting, and Participants. We construct a compartmental model of disease spread for vaccination and routine screening, and study the efficacy of four mitigation strategies (routine screening only, vaccination only, vaccination with partial routine screening, vaccination with full routine screening), and a no-intervention strategy. The study setting is a hypothetical college campus of 5,000 students and 455 faculty members, with 11 undetected, asymptotic SARS-CoV-2 infections at the start of an 80-day semester. For sensitivity analysis, we vary the screening frequency, daily vaccination rate, initial vaccination coverage, and screening and vaccination compliance; and consider three scenarios that represent low/medium/high transmission rates and test efficacy. Model parameters come from publicly available or published sources. Results. With low initial vaccination coverage, even aggressive vaccination and screening result in a high number of infections: 1,024/2,040 (1,532/1,773) with routine daily (every other day) screening of the unvaccinated; 275/895 with daily screening extended to the newly vaccinated in base- and worst-case scenarios, with reproduction numbers 4.75 and 6.75, respectively, representative of COVID-19 Delta variant. With the emergence of the Omicron variant, the reproduction number may increase and/or effective vaccine coverage may decrease if a booster shot is needed to maximize vaccine efficacy. Conclusion. Integrated vaccination and routine screening can allow for a safe opening of a college when initial vaccination coverage is sufficiently high. The interventions need to be customized considering the initial vaccination coverage, estimated compliance, screening and vaccination capacity, disease transmission and adverse outcome rates, and the number of infections/peak hospitalizations the college is willing to tolerate.

Smartphone Use and Well-Being in Two Contexts

Excessive smartphone use is a growing concern in many societies around the world today. To date, attention has primarily been paid to psychological correlates of use, including well-being, with less work concentrating on the role that context plays in smartphone use. This was the goal of the current project. College student smartphone use was measured twice over 1 week in two contexts – a college campus and an outdoor camp – and participant well-being was measured using the SPANE. The findings indicate that daily smartphone use significantly decreased for camp participants and significantly increased for campus participants, and latency to use a phone upon waking significantly increased for camp participants but remained stable for campus participants. Additionally, waiting longer to use a phone upon waking at the end of the week significantly predicted reduced well-being but only for camp participants. Overall, these findings suggest that setting is an important contextual variable to consider when pursuing an understanding of the complex relation between smartphone use and well-being.

The Application of Visual Sensors in the Artistic Design of College Campus Landscape

The research purpose is to solve the problems of low efficiency, low accuracy, and high cost of traditional environmental landscape mapping and landscape volume measurement methods in the artistic design of college campus landscape and make up the defects that the traditional campus monitoring is vulnerable to adverse weather, which results in low monitoring accuracy. Primarily, a binocular stereo vision measurement based on Scale Invariant Feature Transform (SIFT) matching algorithm is proposed, which can realize accurate collection of environmental spatial information and measurement of landscape volume without contact in the process of campus landscape design. Then, the visual monitoring system of college landscape based on the Internet of Things (IoT) is constructed to realize real-time monitoring and early warning of human damage to campus landscape. The proposed method is verified by actual measurement of different objects and simulation experiments using simulation software. Ultimately, the application of visual sensors in artistic design of college campus landscape is analysed by literature analysis. The results show that (1) the error of the improved binocular stereo vision measurement designed here is 52.32% and 59.69% lower than that of the traditional measurement method when measuring the same object with different volumes and the volumes of different objects, respectively, which indicates that the measurement accuracy of the new method is higher. (2) The proposed landscape visual monitoring method based on IoT improves the image recognition accuracy by 21% compared with the traditional digital image monitoring method. The average recognition time is shortened by 12 ms, which ensures the accuracy and improves the recognition efficiency. (3) Through the analysis of existing literature, it is found that the binocular stereo vision sensor can be used to monitor the whole process of landscape construction in real time. The sensor can be combined with social networks, mobile terminals, and physiological monitoring equipment to comprehensively analyse and evaluate people’s preference for campus landscape. The proposed method has broad application prospects in campus landscape design, construction, and maintenance. The research purpose is to provide important technical support for the improvement of the overall image of the college campus and even the city for the design of landscape environment and the technical upgrading of maintenance work in the college campus.

Emergency Management System for College Students based on Big Data Processing Technology

Since 2020, the epidemic of Corona Virus Disease 2019 has swept the world, which has had a great impact on people's life. Especially for college campus life. This paper presents an emergency management system for college students. We use Java Web, big data processing and other technologies to develop, implement and test the system. The system integrates daily management and emergency management, which can meet the basic needs of teachers and students on campus. We hope to provide convenience for students and teachers in learning and management.

Routine, Cost-Effective SARS-CoV-2 Surveillance Testing Using Pooled Saliva Limits Viral Spread on a Residential College Campus

This study highlights the utility of routine testing for SARS-CoV-2 using pooled saliva while maintaining high sensitivity of detection (under 2,500 copies/ml) and rapid turnaround of high volume (up to 930 samples in 8 h by two technicians and one quantitative PCR [qPCR] machine). This pooled approach allowed us to test all residential students 1 to 2 times per week on our college campus during the spring of 2021 and flagged 83% of our semester positives.
