The present study highlighted the importance of raising awareness among the attendants regarding their working conditions, mainly due to the high exposure to toxic compounds. At this core, resistance to use PPE by these workers comesfrom sociocultural issues that notoriously influence the conditionsimposed by this service. In this logic, the case study, determined by the book of Research Methodology by Marconi and Lakatos (2003), thistheme is based on data collection at gasstationsin the city of Salvador- BA, in 2021, to highlight the situations faced by these professionals and, consequently, the impacts on their quality of life and health. The resistance to the use of this equipment harms the present and future well-being of the attendants.

Proposing a Method for Assessing Fuel Consumption and Pollutants Emissions with the Use of Continuously Variable Transmission in Town Cars

The 21st century brings countless social, economic, environmental, and technological challenges to humanity and, to face them, the United Nations (UN) created the Sustainable Development Goals (SDGs). The auto industry, which is part of the private sector, aims to reach them. In this context, this study aims to evaluate the consumption and emissions of pollutants by using an automatic transmission of the CVT (Continuously Variable Transmission) type concerning the automatic transmission of the "Planetary" type. This study will be based on the Consumption/Energy Efficiency tables, published annually by INMETRO (National Institute of Metrology, Quality, and Technology) and whose data will be processed and evaluated using the Quik Sense Software. Thus, the work aims to appraise the advantages of vehicles with automatic transmission of the CVT type about fuel consumption, energy efficiency and emissions, in markets such as Brazil, where these vehicles use ethanol or a mixture of gasoline with up to 27 as fuel % Ethanol. This research can contribute to studies of emission control and approval, benefiting the automotive industry in general, government agencies, the environment, the economy, and society, contributing to the UN's SDGs achievement.

The Paradox and Dynamic Betweem Sustainable Development and Corporate Performance

This article discusses the false antagonism between sustainable development and corporate performance amalgamated with the search for innovation, intensive use of technologies, and global awareness, during the COVID-19 pandemic scenario and the transformations imposed on society, together with the effects of the necessary insertion of new technologies such as Artificial Intelligence. The study highlights the interaction between elements of a technological revolution that imposes profound changes in society, organizations, and, at the same time, unprecedented health and environmental crisis that put at risk the capacity of human resilience to build the future, and opportunities to reconcile socio-economic advances and sustainability practices.

Statistical Analysis of Factors Related to Suicide Records in the World Between 1985 and 2020

Suicide is considered by the World Health Organization (WHO) as a public health problem that afflicts the whole society and it counts more deaths than many diseases. Therefore, the current objective is to analyze the suicide deaths between 1985 and 2020 and classify them according to the act. Through KNN, this study presents suicide cases grouped by sex (male and female) and associate them to factors by country, pointing out information that allows us to understand what influences the act the most directly or indirectly. The results showed that, unlike other researches, the rate of suicide does not have differences based on sex. However, further studies are needed.

Technological Prospection with a Focus on Assistive Technology in Adapted Vehicles for People with Disabilities

This study aimed to review the production of patent documents related to assistive technology on adapted vehicles for people with disabilities. The technological prospection was carried out through a search on the Espacenet database, resulting in 277 patents whose data we organized into charts. The results show that the total number of patents filed in this area is small and with a limited increase over the years, maybe due to industrial secrecy. Twenty-eight countries registered patents. The Republic of China and the Korea Republic were the main depositors, while Brazil registered only one patent. They focused on people with a physical disability, so further projects to attend to other types of disability are also required. There is a necessity to increase government and private sectors investments for technological advances in this area.
