Use Of Social Media

The study assesses the use of social media by rural residents. The study was conducted in Lublin county in 2016. Residents of rural areas (especially farmers) are a social group perceived to be the least technologically developed, the latest in adopting innovations and least advanced in using electronic devices. However, in recent years, differences between city dwellers and rural area inhabitants have been decreasing. Until today, in Poland, not all residents of rural areas have telephones or internet access. The explanation could be that their work does not involve using a computer as in the case of, for example, an insurance agent, architect or journalist. It was found that differences in the category of household equipment involving the possession of a computer and access to the Internet are diminishing – the largest increase has been recorded in recent years in the scope of access to broadband Internet. In the study, a visible relationship between the use of social media and the education of respondents was observed.

This study is an exploration of the digital divide between urban and rural areas, and it was conducted to assess the impact of the minimum living guarantee system on online education in China. The results of the research showed that 83.38% of students in low-income families have been able to participate in online education at home during the pandemic, while 16.62% of students in low-income families have been unable to do so. The absence of computers, smartphones, and broadband Internet access in low-income households reduces the likelihood of children being able to participate in online education at home. In terms of accessing online education at home, students from urban areas have obvious advantages over those from rural ones, and students from minimum living guarantee families have obvious advantages over those from marginal minimum living guarantee ones. This study also showed that the presence of online education-related amenities, including computers, smartphones, and Internet access, mediates the relationship between the subsistence allowance system, Hukou, and accessibility of online education. To address this issue, this paper includes suggestions for bridging the digital divide in online education.

The Internet has become entrenched in the U.S. economy over the last 15 years;access and use of the Internet has increased for all regions of the United States, most types of households and work places, and all income groups. In this chapter we explore how access technologies may affect household on-line activity patterns and address some of the aspects that differentiate urban and rural household Internet use. Rural households are less likely than urban households in having broadband Internet access but this varies regionally across the country. Study suggests that broadband Internet access is no longer perceived a luxury, but as a necessity and that there is pent-up demand for broadband Internet access in rural areas.

Seed Processing

The use of electrophysical influences for pre-sowing treatment of seeds is an effective way to increase their sowing quality. The use of these methods is limited by the fact that their implementation requires new technological equipment in grain processing lines. This problem is solved more easily when pre-sowing processing is performed using installations for active ventilation and grain drying. (Research purpose) The research purpose is in determining the possibility of using active ventilation units and ultra-high-frequency convective grain dryers for pre-sowing grain processing and to evaluating the effectiveness of such processing using computer modeling. (Materials and methods) It is necessary to ensure the uniformity of processing with external influence the seeds placed in a dense layer. Authors carried out pre-sowing treatment of seeds on real installations. Treated seeds were sown in experimental plots and the results of treatment were evaluated. (Results and discussion) The article presents graphs of changes in grain temperature and humidity during processing. To check the feasibility of pre-sowing treatment, authors performed modeling of air-heat and ultra-high-frequency convective seed treatment processes. Based on the results of field experiments, air-heat treatment stimulates the development of secondary plant roots, contributes to an intensive increase in the green mass of plants; ultra-high-frequency convective seed treatment allows increasing the number of productive stems in plants, the number of ears in one plant. (Conclusions) Technological equipment designed for drying and active ventilation of grain can be effectively used for pre-sowing seed processing. In the course of field experiments, it was revealed the possibility of controlling the structure of the crop using different types of external influence on seeds during their pre-sowing processing.
