Improvement of attention in subjects diagnosed with hyperkinetic syndrome using BIOVIT Simulator

This study aimed to stimulate the brain's executive function through a series of tasks and rules based on dynamic perceptual stimuli using the Biotechnology Virtual Immersion Simulator (BIOVIT) and thus evaluate its usefulness to maintain and increase attention levels in subjects diagnosed with hyperkinetic syndrome. With a quantitative methodology framed in a longitudinal trend design, the cause of the exposure-outcome relationships was studied using the BIOVIT simulator. Exploratory analysis of oscillatory brain activity was measured using a graphical recording of brain electrical activity and attention levels. Data consisted of 77,566 observations from n = 18 separately studied participants. The findings established that the BIOVIT simulator maintained and increased the attention levels of the participants by 77.8%. Furthermore, the hypothesis was tested that virtual reality immersion technologies significantly affect attention levels in participants aged 8 to 12. The evidence shows that the BIOVIT simulator is an alternative to developing learning methodologies in vulnerable populations. The low implementation costs and the diversity of academic applications may allow schools in developing countries to solve this problem that afflicts thousands of children with attention deficit and hyperactivity disorder.

Impact of digital economic activity on regional economic growth: A Case study from northern Minas Gerais between 2009 To 2018

At present, the economic measurement of the national statistical offices has not defined or captured the benefits of the digital economy activity due to the low quality or inexistence of methodologies. Currently, there is a relevant debate on the capacity of the digital economy activity to generate productivity, economic growth, and well-being through innovation and knowledge. For this reason, this research identified and studied specialized knowledge, human settlement, and digital economic activity as the factors that influence regional economic growth. As a result, the impact generated by a new business operating models based on information technology was measured. Furthermore, this research used an empirical measurement model that made it possible to identify certain phenomena such as regional poles of regional economic development (PRDE) that surround economically flourishing regions. In addition, it showed that municipalities with high degrees of economic growth were impacted by digital economic activity and specialized knowledge. This finding is consistent with economic growth theories that point to technological evolution as the main factor of modern economic growth. Consequently, this study contributed beneficial results to the local government to develop strategies framed in solving industrial cooperation of economically flourishing regions with their neighbors, facing the problem of agglomeration of resources and capital reflected in human settlement promote an imbalance in economic growth and social development.

Skills-based on technological knowledge in the digital economy activity

This research seeks to measure the impact of people with technological knowledge on regional digital economic activity and the implications of prosperous cities' contagion effect on neighbouring ones. The focus of this study is quantitative, cross-sectional, and its design is correlational-causal. This study covers seven micro-regions of Minas Gerais in Brazil, organized in 89 municipalities, with 69% urban population and 31% rural. The data used consisted of 4,361 observations obtained in the Brazilian government's public repositories, organized into panel data, and analysed using partial least squares, micro-regional spatial regression, and identification patterns with machine learning. The confirmatory analysis of the regression test establishes a significant impact between the CE's technological knowledge and the digital economic activity AED through a predictive value of R2 = .749, \b{eta} = .867, p = .000 (value t = 18,298). With high notoriety among the variables, public and private university institutions (IUPP), professors with doctorates and masters (DCNT), and information technology occupations (CBO). A geographic concentration of companies that demand technology-based skills had effects by slowing down the development of small municipalities, suggesting the development of new government technology initiatives that support new business models based on technological knowledge.
