Objectively evaluating urban ambient air quality and analyzing its influencing factors are of great significance for understanding the current status of air quality and controlling pollution sources. In this paper, logistic regression analysis is carried out for 366 days of air quality data from January to December 2020 in Zibo City, Shandong Province, with air quality class as the categorical variable, and six variables, PM2.5, PM10, SO2, CO, NO2, O3, are selected as pollution indicators affecting the air quality in Zibo City, and the stepwise regression method is utilized to establish a model and determine the weights of each pollution indicator. The established model is used to predict the samples of Zibo City, and the predicted data and actual data are compared to test the fit of the model. The results show that the logistic regression model fits well, and SO2 is the strongest factor affecting air quality, and the probability of air pollution is 1.035 times higher for every unit it increases and other variables remain unchanged, providing a basis for controlling the emissions of the primary pollution factors.

Post internship is a way for students to participate in production work directly after learning knowledge and skills, which is of great significance for students’ future employment and development. As a place to train high-quality and skilled talents, on-the-job practice is an important link in education and an important way to complete the talent training program. In order to effectively improve students’ mastery of professional knowledge and complete the cultivation of students’ good quality and professionalism, secondary vocational colleges should actively lead students to carry out on-the-job internships, so as to effectively promote the development of students and the construction of secondary vocational colleges.

The purpose of this study was to examine how horticultural therapy affects the subjective well-being of college students. Through theoretical analysis and literature review, the study focused on the role of horticultural therapy in mental health promotion, emotion regulation, self-efficacy enhancement, and creativity and cognitive function enhancement. It was found that horticultural therapy can significantly improve the mental health of university students, especially in stress management and emotional stability. Participation in horticultural activities helped to increase students’ life satisfaction, reduce negative emotions, and enhance their self-efficacy and sense of achievement. In addition, horticultural activities have been found to promote creative thinking and cognitive development. Nonetheless, there are challenges to implementing horticultural therapy, including resource and space constraints, and inconsistent participation. This study proposes that integrating horticultural therapy in a university setting requires a combination of resource allocation, curriculum design, and interdisciplinary collaboration. In summary, horticultural therapy demonstrates the potential to be an effective tool for enhancing the subjective well-being of university students, but its successful implementation requires further strategic planning and research.

This paper examines virtual museums’ role in preserving cultural heritage and education in the digital age. Using VR and AR, virtual museums overcome physical limits of traditional museums, offering an immersive, anytime, anywhere experience. This boosts cultural heritage accessibility, engagement, and artifact preservation. Their educational applications are also noted for interdisciplinary learning. Yet, with rapid technological growth, virtual museums face challenges like technological updates, data security, and privacy. The study underscores the importance of virtual museums in protecting and passing down cultural heritage in the digital era, and their value to society and education.

Addressing the challenges of limited noise suppression, inaccurate edge detection, and poor adaptability encountered in the detection of workpiece image edges in complex industrial environments, this study introduces an adaptive algorithm for edge detection that integrates morphological processing with the Canny operator. Firstly, a weighted adaptive morphological processing is designed to extract the gradient magnitude and direction. Secondly, this extracted information is weighted fused with the gradient magnitude and direction obtained from the traditional Canny operator. Subsequently, an adaptive dual threshold algorithm is devised for edge detection and connection. Finally, the proposed algorithm is experimentally validated using images collected from industrial robot assembly lines. The results demonstrate that the proposed algorithm outperforms traditional methods, detecting more effective and continuous edges with significant noise reduction.

With the increasing severity of global climate change, achieving carbon peak and carbon neutrality has become a shared responsibility of the international community. As an important way to reduce greenhouse gas emissions and promote energy structure transformation, the coordinated development of the industrial chain and innovation chain of new energy vehicles has become the key to achieving the “dual carbon” goal. This article aims to explore how to promote the effective integration and coordinated development of the new energy vehicle industry chain and innovation chain through policy guidance, technological innovation, and market mechanism optimization under the guidance of the “dual carbon” goal, in order to provide strategic support for achieving the dual goals of sustainable economic development and environmental protection.

Vocational education is undergoing a period of transformation and development in sync with the economy and society. The evaluation content of automotive inspection and maintenance majors in vocational colleges has also changed rapidly with the development of various education systems. This article analyzes the shortcomings of the evaluation courses of these majors and identifies a series of specific improvement issues. It also proposes countermeasures and suggestions to address the limitations of this profession from the perspectives of evaluation methods, objectives, and staff. By laying a solid foundation for students’ future growth, this article aims to promote the continuous improvement of their comprehensive qualities and foster good study habits.

Some colleges and universities in the management of campus non-motor vehicles in the process of the use of “personal files” a new means. In theory, such means should be characterized as administrative punishment, and its establishment and implementation should be subject to the legal regulation of the “Administrative Punishment Law”.
