This paper is to analyze the connotation of network security literacy by conducting a questionnaire survey on the level of college students' network security literacy. It analyzes the data in detail from four sub-dimensions: network security awareness, network security knowledge, network security skills, network security law and ethics. According to the analysis results, it provides reference for the improvement of network security literacy level of college students.

Rural revitalization is a strategy proposed in the report of the 19th National Congress of the Communist Party of China, and agricultural and rural issues are fundamental issues related to the national economy and people's livelihood. The era of integrated media has strengthened the trend of integrating media and society, and an intelligent media society has arrived. In today's era, the relationship between media and economic and cultural revitalization is increasingly close. As the main position for cultivating media talents in the new era, media majors in universities should shoulder the heavy responsibility of rural revitalization. Media majors in universities can integrate professional resources by offering public elective courses, promoting practice through social practice and discipline competitions, reaching out to the countryside, disseminating national culture, enhancing the cultural identity of rural residents, and assisting in cultural inheritance, innovation, and development.

With the comprehensive and rapid development of China's social economy, the effectiveness of rural revitalization is becoming increasingly significant. Rural revitalization requires various talents, and in this process, the aging population in rural areas also plays a promoting role in rural revitalization. Fully leveraging the experiential, political, and prestige advantages of silver hair, empowering rural revitalization, is conducive to promoting the prosperity and development of social, economic, and cultural development. Therefore, in the context of emphasizing the comprehensive promotion of rural revitalization in the report of the 20th National Congress of the Communist Party of China, it is necessary to attach importance to the practical functions of the elderly population in rural areas and achieve their positive role.

Under the background of "Three Integrity Eeducation", various aviation universities are vigorously carrying out curriculum ideological and political reform. According to the characteristics of undergraduate aviation professional courses, we set up curriculum ideological and political teaching teams, to learn curriculum ideological and political experience, constantly explore ideological and political elements, actively explore the integration of ideological and political elements into professional courses, and promote curriculum ideological and political construction at different levels. Guided by the model curriculum, the teaching reform and practice are carried out from the aspects of teaching objectives, teaching content and teaching design to improve the ideological and political education effect of undergraduate aviation courses.

The cultivation of responsibility among college students in the new era is an important part of the national talent cultivationIt is of strategic significance for college students to practice the core socialist values, establish a positive attitude towards life,and better shoulder the responsibility of national rejuvenation. College students' sense of responsibility, which is organically composed of personal responsibility, national responsibility, and mission responsibility, needs to be guided and cultivated from multiple levels such as individuals, families, schools, and society, in order to better accumulate strength from young people for the great rejuvenation of the Chinese nation.

The development of digital technology has made the form of Labor education transformed towards digitization and intelligence in local engineering colleges. Local engineering colleges should actively adapt to the new opportunities and challenges brought by digital transformation, to identify changes accurately, anchor the development demands of digital labor education, create a new pattern about labor education and technological strengthen; to react to changes actively, follow the logical agreement of digital labor education, reach a new consensus on knowledge transmission and value guidance; to seek changes positively, navigate the practical path of digital labor education, achieve new exploration of intelligent transformation and integrated development, in order to promote the innovative development of labor education.

With the rapid development of Chinese new energy vehicle industry, the demands for new energy vehicle serviceman are rapidly increasing. Due to the high voltage level of the power battery about new energy vehicles and the relatively complexity of motor control system, new requirements have been put forward for the technical and skilled talents trained in vocational colleges. The article analyzes the low-voltage control circuit experiment for special operations of new energy vehicles, laying a solid foundation for improving students' electrical maintenance ability of new energy vehicles.

Based on the theory of high-level echelons, this article selects A-share listed chemical companies from 2017 to 2020 as samples to examine the relationship between the characteristics of senior management teams in chemical companies and corporate performance, as well as the moderating effect of corporate environmental information disclosure. The research results indicate that there is a significant negative correlation between the average tenure of senior management teams in chemical enterprises, the proportion of female executives, and corporate performance. The disclosure of environmental information in chemical enterprises significantly weakens the negative correlation between executive team characteristics and corporate performance.

 An improved Genetic Algorithm (GA) is proposed to solve the problems of poor initial solution,local optima and low aceuracy of the traditional GA for solving the Travelling Salesman Problem(TSP).Firstly,the greedy algorithm is combined with elite selection to improve the quality of the initial solutions in the population. Secondly , the steps of adaptive crossover and mutation probability are designed, and the Metropolis criterion is combined to prevent the genetic algorithm from falling into local optima.Finally, Bidirectional Three- Cross of Greedy Algorithm and 2-opt search algorithm are added to improve the accuracy The results show that the deviation rate of the optimal solution of the improved genetic algorithm is less than 1.88%, and the deviation rate of the mean is less than 2.27%.
