As short video addiction has gradually become an emerging Internet behavioral addiction, its negative impacts on the student population have been noticed and cannot be ignored. Based on a literature review, this study referred to the person-process-content framework and drew on the ecosystem theory to define the relationship between short video addiction, learning avoidance motivation, learning commitment, and silent classroom behavior by using structural equation modeling. This study recruited 1000 participants from Chinese vocational colleges to fill out questionnaires. With an effective recovery rate of 94.6%, there were 946 effective study participants comprising 445 males (47%) and 501 females (53%). After it was confirmed that the data passed the reliability and validity tests, structural equation model analysis was carried out. The study results showed that short video addiction was positively correlated with learning avoidance motivation, but negatively correlated with learning commitment; on the other hand, study avoidance motivation was negatively correlated with learning commitment, but positively correlated with silent classroom behavior. Meanwhile, there was a negative correlation between learning commitment and silent classroom behavior. As a result, the negative correlation between short video addiction and learning behavior needs attention from parents and teachers.

In an attempt to prevent and control the outbreak of COVID-19, education systems worldwide have comprehensively implemented online courses to fulfill the educational goal of the suspension of classes without suspending school. Numerous online courses have been developed under these circumstances. From the perspective of sustainable development goals, these online courses should be continued. However, as the epidemic gradually eases, it is questionable whether or not students will still willingly participate in these courses. The method of teaching is a critical issue for schools to decide. Compared with other related educational research, the research on the vocational education system is still limited. To expand the understanding of this topic, this study adopted snowball sampling and invited students from Chinese vocational colleges to fill in a questionnaire to help understand the perceptions that affect students’ expectations, attitudes, perceived effects, and satisfaction and the persistence of online learning. A total of 819 valid questionnaires were retrieved, with an effective questionnaire response rate of 81.9%. Meanwhile, under the framework of Expectation Confirmation Theory (ECT) and the Technology Acceptance Model (TAM), this study extended the theoretical model and proposed a sustainable model. The results of this study showed the following: 1. Expectancy belief and online learning attitudes had a positive impact on perceived ease of use and usefulness; 2. Perceived ease of use had a negative impact on practical class satisfaction but a positive impact on theoretical class satisfaction and perceived usefulness; 3. Perceived usefulness had a negative impact on practical course satisfaction but a positive impact on theoretical course satisfaction; and 4. Both types of course satisfaction had a positive impact on continuous use intentions for learning.

The smell of space is inseparable from the sustainable development of the living environment. The research on olfactory perception and smell landscape has a positive effect on landscape design and urban planning and contributes to the formation and design optimization of unique urban memory. This study combines urban smell tracking experiments with Internet social media data analysis to classify smells in the old city center of Guangzhou, China, and analyzes the study within the inner ring and six historic districts. Based on the research results, the smell map was drawn, and the reliability of the smell map was tested through social data and semantic analysis. The emotional score heat map of smell and emotion in six regions was constructed, highlighting the impact of smell in key neighborhoods on the environment. In the conclusion to the study, the thematic routes of green urban design are proposed: sightseeing routes, cultural routes, and food routes, as well as improvement strategies to promote the integration of smell and urban operation activities and the sustainable development of urban regional characteristics.

Due to the rapid innovative applications of technological education as a result of the swift development and popularity of telecommunication and wireless technologies, ever-more diversified methods of technological education play a critical role in various education and lecturing activities, without time and distance restrictions. Currently, in order to bridge the urban–rural development gap, the Taiwanese Government has introduced a lot of policies to encourage teenagers to return their hometowns; however, these policies have not achieved their goals, as the most of Taiwanese community development associations faced scarcities of professional knowledge without any educational support during the development of their various schemes, such as economic development, environmental protection, cultural heritage, public services, etc. As a result, local development depends on entire community development associations, especially in the most mountain regions of Taiwan. Moreover, community development associations have a lot of social responsibilities, such as age-related caring activities, driving local economies and industrial development, environmental protection and education, maintaining and developing traditional cultures and arts, etc. Due to the digital characteristics of technological education, most Taiwanese rural community development associations are able to obtain professional information and data about courses without space and time restrictions. Thus, after strengthening and satisfying professionals’ demands, local economies will achieve growth and, therefore, younger persons would be encouraged to stay their original area, thus stimulating the development of rural community development associations. Eventually, the positive development cycle is predicted to increased and, as a result, the urban–rural disparities will be directly diminished by the diversified application of technological education in Taiwan.

Owing to the severe development and progression of climate change and the greenhouse effect, carbon neutrality has attracted much research interest in environment-related social research. Specifically, in Article 12 of the Regulations on Community Development Work (RCDW) for more than 25,000 Taiwanese community development associations, carbon neutrality is the main purpose of environmental education, environmental protection and infrastructures, and social responsibilities. Carbon neutrality has to be instituted into efficient governance and operations to provide effective and diversified services for residents’ lives. Thus, sustainable strategies (environmental, social, and governance, ESG) need to induce effective and efficient carbon-neutral sustainable development in order to improve environmental conditions for the community’s residents without long-term government compensation and resources. Environmentally sustainable strategies focus on environmental protection and education for the whole community. Social strategies need to be associated with social responsibility and public services, while governance needs to be concentrated on sustainable operation and management. In this study, effective and efficient carbon-neutral sustainable development strategies were proposed for the community sustainability of community development associations.

With respect to widely evaluating and elementally assaying the comprehensive possible applications of Internet of Things (IoT) technology for efficiently advancing administrative and operating performances during the implementation of community development missions, this research attempts to initially analyze the various means of employing Internet of Things (IoT) technology by assessing the affairs and activities of 6918 contemporary community associations in Taiwan in order to inductively construct the most effective Internet of Things (IoT) digital system, not only to update their original documentary administrative system to easily and conveniently implement and record administrative missions, activities, and services but also to handle and display the bulk of news and information from most community residents and the Taiwanese government (such as the Council of Agriculture, Executive Yuan). However, after conducting a systematic survey on research related to the Internet of Things (IoT) technology in recent years, there is no one able to directly analyze the shortages and challenges of the diversified applications of Internet of Things (IoT) technology in administrative performance. Specifically, the greatest challenges are the Taiwanese individual information protection regulations and the laws regarding the various applications of digital data (such as the Taiwan Personal Data Protection and Telecommunication Acts), which apparently hinder the development of Internet of Things (IoT) technology in the enhancement of community associations in Taiwan. Therefore, the suggestion contributed by this research is to institute basic digital data using ACT for all 6918 community associations in Taiwan in order to directly force the application of IoT technology to advance the performances and achievements of community development associations.
