Given the existing environmental problems, working with Environmental Education in Early Childhood Education is essential to awaken in children the interest about nature and promote the transformation of values. The Environmental Education proposal delimited here was applied in the municipal pre-school system of Uberlândia - MG, as an alternative to, initially, bring awareness to a group of 18 chidren, aged from 2 to 4 years old, as well as their families regarding the preservation of the natural resources, especially in relation to the themes of Water and Ecological Footprint. This research was carried out through a qualitative approach, using action research as a method, in which the child and the family actively participate as researched and researchers in the entire project. The chidren and their families participated in both the remote teaching modality, due to the pandemic caused by Covid-19, as well as the face- to-face teaching modality. From previous diagnosis of chidren’s Knowledge about the topics covered in the research applied in the investigated group, several pedagogical strategies were adopted: chidren’s educational videos on the themes, storytelling through theater and book reading, music, dance, games and surveys applied in the form of images, all based on action research and with a content-rationalist educational approach. The proposals applied aimed at raising consciousness among chidren and their family members regarding pollution, contamination, water importance and its waste, focusing on its usage in daily activities and diseases related to it. The analysis of the results revealed that motivating pedagogical strategies are potential for raising awareness among students, but that they must become continuous to reinforce the environmental problem of the water crisis that devastates the world, as well as to establish in these individuals and their families the notion of conscious consumption. ; Pesquisa sem auxílio de agências de fomento ; Dissertação (Mestrado) ; Diante dos problemas ...

Diante do cenário global da gestão de resíduos sólidos, observa-se que apesar de possuirmos plásticos com alta capacidade de reaproveitamento, eles não são orientados para os melhores destinos e com a evolução e aperfeiçoamento dos processos, a demanda e produção destes produtos só aumentou, com isso observa-se o acúmulo de resíduos sólidos gerando diversos impactos ambientais. Observando esse cenário, e o senso de urgência expresso pelas organizações mundiais nos últimos anos, muitas empresas passaram a adotar medidas de economia circular nos seus processos produtivos e internos, com o objetivo de diminuir os impactos ambientais causados. Por meio dos resultados obtidos foi possível analisar que as principais empresas do setor apresentam poucos resultados significativos para uma avaliação qualitativa dos indicadores de sustentabilidade. Com isso observa-se que a realização de investimentos em sustentabilidade traz aumento de lucro significativo a um longo prazo. Analisando-se os dados de reciclagem obtido principalmente nos últimos 3 anos tem-se que a mudança de consumo de embalagens em decorrência da COVID-19 gerou um aumento expressivo de resíduos e em sua maioria plásticos. Entretanto, esse aumento não foi devidamente controlado pelas gestões municipais devido à falta de recursos. Fica evidente que no país a gestão de resíduos sólidos ainda é muito ineficaz sendo um dos principais locais de destino os lixões que causam sérios problemas ambientais. ; Because of the global scenario of solid waste management, it is observed that despite having plastics with high reuse capacity they are not directed to the best destinations, and with the evolution and improvement of processes, the demand and production of these products have only increased, and with this we observe the accumulation of solid waste generating various environmental impacts. Observing this scenario, and the sense of urgency expressed by global organizations in recent years, many companies have started to adopt circular economy measures in their ...

This dissertation organizes and describes Design perspectives and approaches that seek to advance design practices for the development of solutions that meet emerging needs in the contemporary world, and argues that the starting point is in education. Thus, the objective of this research was to identify how the teaching of Design can contribute to the sustainability of food delivery packaging, as these have increased in the pandemic scenario. To this end, it carried out an ex-post facto case study in the disciplines of Packaging Design and Design for Sustainability, in the Graphic Design course at the State University of Londrina, which were integrated and taught in the context of the COVID-19 pandemic. As a methodology, it sought bibliographic references on teaching Design, sustainability, food delivery packaging and urban solid waste. For the analysis of the subjects selected for study, the research adopted the phenomenological philosophical stance and inductive logic, as the predominance of the research is qualitative and sought to understand the variables that contributed to the analyzed data. The analysis carried out shows that the development of the disciplines sought to assimilate their teachings in the area of packaging creation with the environmental impacts caused by the pandemic caused by COVID-19 and the waste that disposable packaging caused in this period due to the increase in orders via delivery. According to the experience in teaching reported, it was possible to perceive that the insertion of a reflective thought around the environmental problem and Design, from a dialogic practice, allows a horizontal construction of attitudes that allow each individual to participate in the formation of the individual and collective knowledge. Taking into account the results of the effort to build socio-environmental values in a more democratic way, we can consider that the integration of disciplines brought an opportunity for the joint construction of principles such as autonomy, democracy and cooperation ...

As mudanças climáticas são reconhecidas como um dos maiores desafios do século XXI, implicando em sérios agravos socioeconômicos e à saúde global. Os grandes centros urbanos sofrem profundamente as consequências causadas pelas mudanças climáticas e poluição atmosférica, bem como contribuem diretamente para a intensificação desses fenômenos. Diante disso, esta pesquisa tem como objetivo central investigar as relações entre os gases de efeito estufa, indicadores de saúde e econômicos do estado de São Paulo, entre 2000 e 2020. Procurando solucionar, de maneira completa e sistematizada, cada objetivo específico proposto, optou-se pelo formato multipaper, constituído por uma coleção de artigos científicos independentes, porém interrelacionados. O artigo 1, a partir de uma análise descritiva das séries temporais dos principais gases de efeito estufa, mostra que o setor de transportes é o principal emissor de CO2 do estado. O artigo 2, valendo-se da melhora da qualidade do ar, utiliza a função de risco relativo para associar diminuição da concentração de poluentes com mortes prematuras evitadas. Os valores encontrados representaram uma economia de aproximadamente 8 milhões de dólares, durante a greve dos caminhoneiros de 2018. O artigo 3 também utiliza a função de risco relativo e revela que a redução da poluição atmosférica, no início da pandemia de COVID-19, resultou em mortes prematuras evitadas, que representaram uma economia de 720 milhões de dólares. O artigo 4 trata-se de uma revisão sistemática sobre os principais modelos econométricos aplicados para estabelecer a relação entre CO2, PIB e consumo energético. O Artigo 5 compara a precisão de três diferentes métodos, regressão linear multivariada, regressão elastic-net e redes neurais artificiais, e demonstra a superioridade deste último em modelar as emissões de CO2, a partir do PIB e energia (MAPE = 0,76% e R2 = 1,000). A partir da análise de diferentes estruturas de redes neurais artificiais, o artigo 6 demonstra que, durante o verão, a temperatura máxima é o ...

With the profound transformations caused by the Covid-19 pandemic and contemporary hyperconnectivity, the internet has become an important tool for physical retail, allowing stores to expand into the virtual environment. However, in this challenging environment, it is crucial to adopt efficient strategies to attract and retain consumer attention and stand out amidst global competition.In this context, digital marketing becomes fundamental to establishing relationships with customers, understanding their needs, and increasing sales and profitability for companies. Before commercializing an infoproduct on a large scale, it is common to carry out digital launches to evaluate consumer interest and adjust the offer according to their demands. This paper aims to analyze the importance of digital marketing for the launch of an infoproduct in the field of solar energy, through a case study applied to the company Solarview. The methodology used was the Seed Launch, proposed by the digital launch expert, Erico Rocha. Based on the results obtained, it can be stated that the first Seed Launch (event called Solar Experience) of the company Solarview was successful. It was possible to make the first sale of the infoproduct "Digital Solar Process Management Course" and generate a profit of R$2,667.65, with a positive ROI of 1.36. The branding results showed a significant growth in followers and engagement on the company's digital platforms during the launch period. On Instagram, there was a 4.75% growth in followers, totaling 648 followers gained. On Facebook, there was a 3.28% growth in followers, totaling 49 followers gained. On YouTube, there were a total of 219 subscribers gained during the period. The Seed Launch was a crucial step for Solarview, allowing the company to test and validate its first infoproduct, as well as measure its efficiency. With the results obtained, the company can adjust its strategy and plan future events, aiming to increase revenue and customer engagement. In a scenario where consumers are ...

Não recebi financiamento ; The Covid-19 pandemic significantly changed the national scenario in a sudden way during the beginning of 2020. This current work has the objective to analyze the impacts of this change in the light of the national energy market. In the context of the generation during 2020, there was a reduction of 6.2% in the supply of non-renewable sources and an increase of 2.5% in the supply of renewable sources, when compared to its offers in 2019, with great emphasis for the solar source supply. The solar generation had an increase of 187% in micro and mini distributed generation. The necessary sanitation management to contain the virus and the political and socioeconomic uncertainty caused a frustration of market expectations and a consequent decrease in electricity consumption. The greatest variations on energy consumption in the National Interconnected System, when compared to the same period in 2019, were observed in 2020 in the months of April and May, which had a reduction of 12.1% and 10.9%, respectively. This decrease, together with the economic downturn and the increase in consumer defaults, caused a reduction in distributors' billing, which motivated the creation of the Conta Covid. The account, which comprises a loan coordinated by BNDES with 16 public and private institutions, was responsible for the transfer of R$ 14.8 billion to the affected distributors in the period. Thus, future tariff adjustments were diluted in 60 months and the sector had more liquidity. In the free energy market, the decrease in national energy consumption caused a drop in the Preço de Liquidação das Diferenças (PLD), which, together with the historical situation, exposed its consumers to the short-term market. It is estimated that the differences between contract prices and the short-term PLD caused a loss of R$ 5 billion in the free energy market during the year 2020 ; A pandemia de Covid-19 alterou significativamente o cenário nacional de forma súbita durante o início do ano de 2020. Este trabalho busca ...

O petróleo é uma substância oleosa baseada em carbono, composta por uma combinação complexa de hidrocarbonetos que pode ser refinada fornecendo combustíveis, solventes, lubrificantes e outras substâncias que estão presentes no dia a dia e na indústria. No Brasil, a Petróleo Brasileiro S.A (Petrobras) foi uma das primeiras e mais importantes empresas a realizar a extração e comercialização do petróleo. Dada a importância da Petrobras e sua influência em território nacional, este trabalho teve por objetivo analisar as quantidades emitidas de poluentes atmosféricos e consumo energético como seus indicadores de sustentabilidade, avaliar as variações anuais médias de suas ações na bolsa de valores, estudar a evolução dos indicadores, e avaliar os efeitos que eventos extemporâneos tem nos indicadores em comparação com outro ano, para o período de 2013 até 2020. Os resultados mostraram que todos os indicadores tenderam à diminuição com o passar dos anos, sendo o consumo de energia o mais eficiente, pois teve a maior queda geral, e o material particulado o menos eficiente. Pode-se observar mudanças significativas no ano de 2016 e 2020, que podem estar associadas à crise hídrica e à pandemia, respectivamente. As ações da Petrobras sofreram desvalorização em 2015 devido à crise hídrica e econômica, e em 2020 principalmente por influência da pandemia de COVID-19. A produção permaneceu praticamente constante no período analisado, com uma leve tendência a aumento. Pode-se inferir ainda que a diminuição observada nos indicadores de sustentabilidade não está associada à queda de produção. ; Petroleum is an oily substance based on carbon, composed of a complex combination of hydrocarbons that can be refined providing fuels, solvents, lubricants and other substances that are present in everyday life and in industry. In Brazil, Petróleo Brasileiro S.A (Petrobras) was one of the first and most important companies to carry out the extraction and commercialization of petroleum. Given the importance of Petrobras and its influence in ...
