• APLICAÇÃO DO MODELO AUTOREGRESSIVO NÃO LINEAR COM ENTRADAS EXÓGENAS PARA PREVISÃO DO NÍVEL DO RIO NO AMAZONAS
  A variação do nível dos rios é um problema constante, a previsão da variação do nível dos rios, trazem uma possibilidade de planejamento em todas as áreas de atuação, que proporciona para uma redução no impacto causado pelas enchentes e vazantes. O presente trabalho se justifica por três linhas básicas que envolvem a problemática do tema, que são o uso da Inteligência Artificial, o problema das enchentes na Amazônia e a questão da tecnologia a favor da tomada de decisão. Os impactos ambientais causados por fatores econômicos e sociais são problemas retratados em cenários como enchentes e vazantes de rios, trazendo à tona situações como aumento de doenças, redução da produção agrícola em locais que dependem de controle geológico preciso, além do aumento em processos erosivos. em locais de risco. Assim, a utilização da IA para prever o nível do rio, que consequentemente pode minimizar os problemas decorrentes de enchentes que causam impacto ambiental, é altamente possível, pois quando se sabe antecipadamente que um evento está próximo de acontecer, as decisões podem ser tomadas que os impactos sejam menores. Este trabalho modela e aplica o NARX para prever o nível do rio na Amazônia com variáveis de fácil acesso e implementação através do software MATLAB, a fim de contribuir com um modelo de previsão capaz de prever uma possível enchente a partir do nível do rio. Para aplicação da metodologia utilizou-se a base de dados as variáveis de entrada do Instituto Nacional de Meteorologia, e variável de saída do site do Porto de Manaus, estação do Rio Negro do porto de Manaus, 31/01/2020 a 30/06/2021. O desempenho dos modelos foi comparado com 5, 10, 15, 20 e 25 passos para frente, considerando meses como horizonte de previsão. O modelo NARX obteve melhor resposta nas previsões dentre as quais destacou-se o horizonte de 15 passos.
• EDUCAÇÃO AMBIENTAL: OS 3R’s (TRÊS ERRES) NO PRIMEIRO ANO DO ENSINO FUNDAMENTAL
  Podemos observar que, presentemente, o corpo social sofre com o dilema do excesso da criação corolário inadequada do resíduo sólido. Esta quantidade demasiada de resíduos tem sido preocupante, pois, se não forem devidamente recolhidos e descartados, ocasionam sérias consequências à saúde e ao meio ambiente. Desta forma, a relutância da não gestão dos resíduos sólidos é numerosa e inclui aspectos ambientais, econômicos, sociais e de saúde. Constata-se, diante deste cenário, que não se pode elidir o resíduo por completo, entretanto, é possível de crescê-lo, diminuindo a obtenção e reciclando ao máximo praticável. É certo que o mundo contemporâneo se caracteriza por um estado quase constante de crises, conquanto, reciclar ou reusar tem sentido de refrear aquilo que se utiliza, para limitar o desperdício e resíduos, proteger o meio ambiente, conservar e defender o ecossistema. Para tanto, há a necessidade de moderar este consumo expresso, não apenas usar o necessário, mas também, reaproveitar o que for possível. A óptica do conceito dos "3R’s" reduzir, reutilizar e reciclar tem como objetivo conter o choque ecossistêmico coma aplicabilidade da redução e conscientização sobre a quantidade de produtos que se consome, minimizando assim o desperdício de materiais e a geração de lixo. Nesta realidade, a reutilização de produtos e objetos evita o consumo exacerbado e a extração de matérias primas. A reciclagem de resíduos sólidos reaproveita estes insumos e aumenta a sua vida útil. Neste sentido, é imprescindível dar ênfase na educação, enquanto agente de mudança, para o desenvolvimento de pessoas em cidadãos informados e ativos. Diante do exposto, o objetivo deste trabalho foi observar, a percepção das crianças do primeiro ano do ensino fundamental sobre o meio ambiente para, posteriormente, realizar a sensibilização de forma, crítica e reflexiva de como nos relacionamos e como podemos melhorar nosso meio ambiente através da redução e do reaproveitamento do lixo. O conceito dos três erres neste estudo de caso foi utilizado, portanto, para o esclarecimento e promoção de reflexão a respeito das compras excessivas, da reutilização daquilo que iria para o lixo como latas, papelões, garrafas entre outros e, finalmente, para oferecer a possibilidade de converter itens não mais utilizados em outras criações. Este estudo contribuiu para a conscientização e preservação do meio ambiente e seu encadeamento didático-pedagógico promoveu progressões no aspecto: viso motor, motor, motriz, lúdico, afetivo e crítico-reflexivo, para a promoção da aquisição e fortalecimento de competências e habilidades.
• AS FORMAS DE DESCARTE DE AGULHAS E SERINGAS EM ÉPOCA DE PANDEMIA DA COVID-19 NO SISTEMA DE SAÚDE DE IRANDUBA
  Elaborar diretrizes baseadas em evidências para tornar o descarte de aparelhos de injeção usados mais seguro é objetivo desta pesquisa. O estudo foi baseado em processo minucioso de observação, especificamente no município de Iranduba, nas unidades básicas de saúde (UBS) localizadas na área urbana e nas unidades não ribeirinhas do referido município do estado do Amazonas, e não em qualquer processo utilizado para observar simplesmente por observar. O estudo foi motivado pelo aumento do interesse em saber como se dava o descarte dessas seringas e agulhas usadas na vacinação contra a covid-19, uma vez que a demanda de vacinados ainda é grande, se comparadas com outras vacinas e, consequentemente, a quantidade de seringas e agulhas descartadas, também, é exageradamente grande, quando se faz a mesma comparação anterior. Também através de uma revisão bibliográfica, buscou-se resumir as melhores práticas baseadas em evidências para prevenir infecções associadas ao descarte de aparelhos/seringas de injeção em ambientes inapropriados. O processo de desenvolvimento incluiu, para sua coleta de dados, análise observacional como eram realizados os descartes dos insumos sanitários, utilizados nas vacinações contra a covid-019 no ano de 2021, além de uma análise da definição de referência da Organização Mundial de Saúde (OMS) e do Ministério da Saúde de um descarte de seringa de injeção em local apropriado e seguro, desde após a imediata utilização até seu descarte final seguido de incineração exclusiva. Uma revisão da literatura para cada uma dessas etapas, a formulação das melhores práticas e o envio do documento preliminar para revisão foram as etapas desta pesquisa. Ao final desta árdua pesquisa, perceptível foi, de forma conclusiva, a forma equivocada e danosa com a qual era feita o descarte de tais resíduos sólidos, porquanto esses matérias, logo em seguida ao seu uso, eram alocados, em uma caixa coletora, juntos com outros insumos sanitários, quiça, esses últimos com possibilidade de reutilização ou reciclagem, o que viria a trazer riscos enormes aos obreiros das UBS diante do risco de infecção da covid-9. Esta dissertação discute apenas o procedimento necessário de controle do manuseio das seringas e agulhas a serem utilizadas na vacinação contra a covid-19.

• AUTOMATION OF TAMBAQUI FISH POND AERATION FOR ENERGY EFFICIENCY IN THE BRAZILIAN AMAZON
  The increase in the demand for fish highlights the aquaculture potential of the Brazilian Amazon.The high cost of electric energy, lack of technical staff and inexistence of continuous control ofwater quality parameters are some of the factorsthat hinder the growth of this activity. We evaluated two opportunities for automation and optimization in commercial tambaqui farms in ponds in Amazonasstate, Brazil. The first is the manual control and recording of physical-chemical properties of the water, and the second is the high consumption of electricity by the aerators. Thus, we developed a continuous monitoring of water quality parameters, through automatic gauging, using a floating platform with onboard sensors, which was called autonomous experimental station (AES), which controls the startup and shutdown of the aerators according to established parameters, providing oxygen necessary for maintaining fish life, eliminating electricity waste and recording the parameters evaluated. As result, after integrating the AES in excavated tanks, it was possible to reduce 26% in electric energy consumption for adult fish and 52% for juvenile fish, besides registering the values of DO, pH, and temperature, generating savings for the producer and contributing to the sustainability of the activity in the Amazon.

• Garlic Peel Surface Modification and Fixed-Bed Column Investigations towards Crystal Violet Dye
  Garlic peel, a low-cost agro-waste, was explored as an adsorbent for the remediation of wastewater containing the crystal violet (CV) cationic dye. The garlic peel was treated with NaOH at 1 : 1.5 ratios in order to modify the surface and increase its porosity. The surface-modified garlic peel was ground to a smaller size in order to increase its surface area and used as an adsorbent in the continuous column investigations. Column parameters such as bed height, flow rate, and initial concentration were optimised and found that optimal removal efficiency was achieved at 3 ml rate of flow, 3 cm column depth, and 100 mg l-1 initial concentration. The surface-modified garlic peel exhibited a higher loading capacity of 99.9 mg g-1 towards CV at optimised conditions. SEM investigations confirmed the surface modification and increase in porosity of the garlic peel. The column data was tending to fit well with Thomas and Yoon-Nelson’s models suggesting the scalability to an industrial level. Regeneration of MGP was successful with 0.01 M HCl solution. These results conclude that garlic peel is a potential agro-waste material that can be used to mitigate water pollution

• PROPOSAL OF A METHODOLOGY OF MANAGEMENT OF THE PURCHASING PROCESS AND COMMUNICATION WITH OTHER AREAS
  In the current context of extreme competitiveness, companies should redirect their efforts to a good service capacity, with a high level of service and the lowest possible total cost. The entire logistics process represents a decisive factor in the company's activity, and the management of purchases in the acquisition of materials and services should be aligned with the strategic objectives of the company as a whole, acting in an integrated manner with the other sectors, in addition to exposing actions guarded by the compliance area to avoid ethical and moral deviations, protecting Corporate Governance. The adequacy of integrity models that meet the rules that comply with current laws has become fundamental in the management of organizations as a strategic way. Therefore, the objective of this study is the implementation of a process model of application of the compliance program and the security of information and data of the company that is of fundamental importance for the acceptance of products or services in the market where they operate, as well as business continuity. The study began with the problem that the failure of communication in the company during internal and external changes can negatively affect the company's results and the conduct of employees. For this, the Inductive Method was elected and thus used a strategic tool such as SWOT analysis, a 5W2H activity mapping tool and PDCA action plan. Thus, the present study can be considered exploratory, of an applied and qualitative nature, in two aspects, bibliographic research and case study. The Research will be by observation and comparison with bibliographic research through a sample of facts identified in the company and reports of employees from various departments, of facts already occurred. Data collection was through meeting and interviewing with the professionals of the companies, reporting on the importance of the theme. We sought to know how to improve communication between the purchasing department with the other departments of the company and with the companies that maintain relationships. The results showed the main tools and compliance mechanism, proposing actions that can be used in practice with the purpose of providing a broad view of the operation of the proposed model, with transparency and ethics, thus increasing the competitiveness of the business.
• THE IMPACT OF PANDEMIC IN SUPPLY CHAIN MANAGEMENT IN AN ELECTRONIC INDUSTRY
  The logistics, social and economic impact caused by the SARS-CoV-2 pandemic has unprecedentedly affected the supply chain of the electronics industry. Logistics was in high demanded during this pandemic period, and it was key actor for chain balance, even faced so many challenges. The objective of this case study is to demonstrate the supply chain of an electronics industry in the industrial pole of Manaus, evaluating the scenario before and during the pandemic, its main difficulties, from the shortage of raw materials up to the high costs of international freights. The final good industry is totally dependent on component industries, the complicating factor is that in general the components are supplied by Asia, and arrive in Manaus by sea and air transport. At the height of the pandemic, ports were closed and flights were canceled, causing impacts on the supply chain. Some components are produced by local industries, however they also suffered shortages of virgin raw materials for processing, triggering consequences on the entire supply chain. The method used was a case study, and used a strategic tool such as SWOT analysis, a quality tool such as ISHIKAWA, and a risk mapping tool such as GUT Matrix and 5W2H action plan. Data were collected through interviews, observations and archival information, allowing the researcher free to walk in the direction of construct solutions, with the author's own experience, who works in the area, an important component of contextualizing the research. From the observation of the data, it was evidenced that the analyzed industry started a crisis management, and actions to mitigate and manage the impacts of the pandemic on its logistics chain and despite the challenges faced, the company's business continuity results were achieved, and bringing maturity to the integrated logistics chain management process.
• OPTIMIZATION OF THE MANUFACTURING PROCESS OF CARDBOARD PACKAGING WITH FUZZY LOGIC: CASE STUDY COMPANY IN THE INDUSTRIAL POLO OF MANAUS

• Removal of Pb2+ Ions by ZSM-5/AC Composite in a Fixed-Bed Bench Scale System
  This investigation suggests the implementation of ZSM-5 activated carbon composite as a prolific adsorbent for the continuous elimination of Pb2+ ions from water. Continuous adsorption experiments were performed by varying three parameters such as process flow rate (2-6 mL min-1), bed height (2-6 cm), and initial concentration (250–750 mg L-1). The highest loading capacity of the fixed-bed 213.3 mg L-1 was achieved with optimal values of 2 mL min-1 of flow rate, bed height of 6 cm, and initial concentration of 750 mg L-1, respectively. The breakthrough curves and saturation points were found to appear quickly for increasing flow rates and initial concentration and vice versa for bed depth. The lower flow rates with higher bed depths have exhibited optimal performances of the fixed-bed column. The mechanism of adsorption of Pb2+ ions was found to be ion exchange with Na+ ions from ZMS-5 and pore adsorption onto activated carbon. The breakthrough curves were verified with three well-known mathematical models such as the Adams-Bohart, Thomas, and Yoon-Nelson models. The later models showed the best fit to the column data over the Adams-Bohart model that can be utilized to understand the binding of Pb2+ ions onto the composite. Regeneration of ZSM-5/activated carbon was achieved successfully with 0.1 M HCl within 60 min of contact time. The outcomes conclude that ZSM-5 activated carbon composite is a prolific material for the continuous removal of water loaded with Pb2+ ions
• Removal of Hydrocarbons from Wastewater Using Sugarcane Bagasse
  The presence of hydrocarbons in wastewater causes innumerable problems for ecosystems and is a pollution problem that needs to be solved. This paper shows the results obtained in the removal of hydrocarbons (diesel) using natural sugar cane bagasse (BN). Thermodynamic and kinetic studies of the biosorption process were carried out at two temperatures: 25 °C and 35 °C and studies in a column packed with (BN) at granulometry (+1–2 mm). The results obtained in the equilibrium and sorption studies were adjusted using the Langmuir and Freundlich sorption isotherm models. The thermodynamic parameters show a predominance of a physical sorption; in a process is exothermic and spontaneous. The pseudo second-order model better fts the kinetics of hydrocarbon biosorption with natural bagasse (R2 ≥ 0.98). The rupture curve where the point is reached 6 h of operation was obtained experimentally. Scanning electron microscopy studies coupled to EDX of depleted BN show that it undergoes changes in its structure, showing a degree of surface dismemberment. The increase in the C/O ratio shows the presence of hydrocarbons that were adsorbed. In the thermogravimetric study, the anaerobic pyrolysis stage of cellulose (200 °C and 400 °C) decreases energetically and the loss of mass is less; this behavior is associated with the adsorbed hydrocarbon (diesel). The results obtained showed that BN has potential as a hydrocarbon biosorbent, with removals of 60.3% of total hydrocarbons (HCT) present in real wastewater, coming from a Power Plant that operates with diesel .
• Modeling and Optimization of 1-Kestose Production by Schedonorus arundinaceus 1-SST
  In current commercial mixtures of inulin-type fructooligosaccharides (FOS) synthesized from sucrose by fungal fructosyltransferases, 1-kestose has superior bifidus-stimulating effect than nystose and frutosyl-nystose. In this study, a recombinant sucrose:sucrose 1-fructosyltransferase (1-SST, EC 2.4.1.99) from the plant Schedonorus arundinaceus (Sa) was the enzyme of choice to maximize the batch production of 1-kestose in a jacketed agitated vessel. Mathematical models were developed to predict the optimal conditions for the sucrose conversion reaction and the subsequent enzyme inactivation to prevent 1-kestose hydrolysis. After programed heat inactivation of Sa1-SSTrec in optimized batch experiments with different enzyme and sucrose concentrations, 1-kestose represented more than 90% of total FOS content (53%-58%, w/w) in the reaction mixture. The mathematical models described herein are suitable tools for the cost-effective production of 1-kestose in scaled batch reactions.
• A SIMPLIFIED APPROACH TO AUTONOMOUS CARS
  Checking the data in December 2018 present in the “Global status report on road safety 2018”, we can see that there is an increase in the number of deaths caused by vehicular accidents reaching an average of 1.35 million deaths every year due to traffic accidents. The document also reveals that injuries caused by traffic are now the main cause of death for children and young people between 5 and 29 years old. Although many safety measures adopted by governments around the world helps to reduce such accidents, the biggest risk factor still persists, which is precisely human driving. To circumvent this factor, much is being studied about self-driving vehicles, where a vehicle can travel on public roads along with the normal traffic flow without the need for human intervention. In this paper we will explore the characteristics of an autonomous car, represented by line-following robots, in an accident-prone situation and study the behavior of vehicles in face of an imminent collision. The robots will follow an infinite loop track, equipped with sensors to detect their position and objects that represent obstacles or cars in front of them. We aim to prove the safety provided by an intelligent locomotion system when communicating with the environment and contribute to the advancement of autonomous vehicle mobility technology.
• SOLID WASTE MANAGEMENT PROCEDURES AT THE MEDICAL CLINIC OF CHILDREN’S HOSPITAL DR. FAJARDO
  To reduce the risk to health and the environment in the handling of hazardous health waste, it is necessary to develop a Standard Operating Procedures (SOP) for the management of Health Services Waste (RSS) that include ensuring correct disposal practices and packaging of waste. hospital. However, hospital waste can cause serious environmental damage, and are potentially more dangerous because they contain chemical and biological residues. In addition, these residues constitute a danger of harm to people's health. It is pointed out that the general objective is to develop and apply RSS SOP in which it encourages its correct management and know-how among the employees of a children's hospital in Manaus-AM. The methodology applied regarding the approach is qualitative-quantitative data, of the descriptive type, and the research procedures are a case study of the Children’s hospital Dr. Fargado (HIDF). According to data obtained, the RSS from groups A, B and E are the main waste collected in the health unit of the children's care network, and are potentially dangerous because they present a risk to the health of HIDF employees and patients. The research also elaborated and presented a SOP on the management of RSS at Children’s hospital Dr. Fajardo for the outpatient sector. The document consists of information such as: waste classification; symbology; packaging; collection and transport; internal RSS management flow; recommended treatments for health waste; risks associated with accidents; and recommendations on health and safety at work in a health unit. Such data are essential for building meaningful knowledge among all people, including staff and patients, about the risks of HSR. The implementation of the SOP on the management of RSS to HIDF employees took place in September, in which employees gained essential knowledge, since safe waste management protects hospital staff, the public and the local environment.
• THE CONTRIBUTION OF THE RURAL ENVIRONMENTAL REGISTRY TO FAMILY FARMERS IN THE STATE OF AMAZONAS, BRAZIL
  Environmental issues continue to be on a growing agenda around the world. A large part of the global concerns is focused on the Amazon, even though it leaves aside almost the entire human contingent that inhabits that space. Except for the Indians. They disregard that many of the harmful environmental impacts are practiced by family farmers because fire is their greatest technology and, in many cases, the only one. Therefore, the management of this territory must create mechanisms and instruments capable of promoting the region's sustainable development, bringing together environmental and social interests, which only can be done through laws. The Rural Environmental Registry (CAR, acronym in Portuguese) aims to implement sustainable public policies. Thus, this literature review study aims to show CAR's contribution to family farmers operating in the State of Amazonas from a legal and environmental point of view. The results show that a) it is necessary to know the main legal aspects of the CAR to understand its environmental importance, b) knowing each of the steps in the preparation of the registry allows this instrument to fulfill its environmental mission as a result of legal discipline, c) the simplification of the regime granted to family farmers and similar populations allows the legal requirements to be fulfilled by this essential human contingent in the Amazon and d) the rigorous execution of the CAR allowed for several conflicts of overlapping rural areas to be resolved, which benefited family farmers and populations equivalent, pioneers in these areas. The conclusion states that implementing the Brazilian forest code is essential for family farming agribusiness, requiring technical support. The CAR emerges as a fundamental instrument.
• CONHECIMENTO DE PROFISSIONAIS DE SAÚDE SOBRE GESTÃO DE RESÍDUOS EM TEMPOS DE PANDEMIA PELA COVID-19: ESTUDO DE CASO NO HOSPITAL FEDERAL UNIVERSITÁRIO GETÚLIO VARGAS EM MANAUS-AM
  A falta de conhecimento adequado sobre o gerenciamento dos resíduos de serviços de saúde (RSS) pode gerar danos locais, como ocorrência de acidentes biológicos com contaminação de colegas de trabalho ou até mesmo de pacientes, além de impactar a longo prazo sobre o ambiente no qual esses resíduos são descartados.

• THE IMPORTANCE OF FUZZY LOGIC INTEGRATED TO INVENTORY MANAGEMENT: CASE STUDY IN A COMPANY X IN THE INDUSTRIAL DISTRICT OF MANAUS.
  Inventory management is a practice of fundamental importance for the success of companies in the most varied segments. Companies that operate with low levels of profitability depend on efficient inventory management, under penalty of losing competitiveness. Efficient inventory maintenance is not characterized by the existence of large batches of products for prompt customer service or, on the contrary, by the lack of inventories in an attempt to minimize maintenance costs. Inventories must be managed in a balanced way to ensure an adequate level of service to customers and generate profits. This work aimed to develop a Fuzzy model for stock management of an organization, to reduce the lack of material in stock, resulting from the "lead time". The work is justified by the importance of having a management monitoring the control of inventory costs, which includes the expenses resulting from the lack of items, the costs related to the replacement of the stock, and the expenses of a stopped stock. To accomplish this, it was necessary to map the Material Purchasing Process and thus identify which were the most significant variables in inventory management. The use of Fuzzy Logic, idealized for a model like this, is to reach an inventory level close to zero, immediately before physical replacement, thus minimizing unnecessary costs. Therefore, experimental research aims to manipulate and control the research variables. The application of the developed model shows that the evaluation of Inventory Management through the Need for Replacement of Input and Type of Transport to be used through the fuzzy methodology proved to be viable to assist the desired observations, allowing to understand the impact of each linguistic variable in the research result, pointing out how company X can use the information obtained to improve the structure of its Logistics Process, thus reducing the lack of material in stock due to the lead time.
• ENVIRONMENTAL EDUCATION: THE 3R's (THREE R’S) IN THE FIRST YEAR OF FUNDAMENTAL EDUCATION
  We can observe that, at present, the social body suffers from the dilemma of the excess of the inadequate corollary creation of solid waste. This excessive amount of waste has been worrisome because, if not properly collected and disposed of, it causes serious consequences to health and the environment. Thus, the reluctance of the non-management of solid waste is numerous and includes environmental, economic, social, and health aspects. In this scenario, it is clear that waste cannot be completely eliminated; however, it is possible to decrease it by reducing the amount of waste and recycling as much as possible. It is true that the ontemporary world is characterized by an almost constant state of crisis, however, to recycle or reuse has the sense to restrain what is used, to limit waste and residues, to protect the environment, to conserve and defend the ecosystem. For this, there is a need to moderate this expressed consumption, not only to use what is necessary, but also to reuse what is possible. The optics of the "3R's" concept aims to contain the ecosystemic shock with applicability to the development of new products. In this sense, it is essential to emphasize education, as an agent of change, for the development of people into informed and active citizens. In view of the above, the objective of this work was to observe, the perception of children in the first year of elementary school about the environment to, subsequently, make them aware in a critical and reflective way of how we relate to each other and how we can improve our environment through the reduction and reuse of waste. The concept of the three Rs in this case study was used therefore, to clarify and promote reflection regarding excessive shopping, the reuse of what would go to waste such as cans, cardboard, bottles among others, and finally, to offer the possibility of converting items no longer used into other creations. This study contributed to the awareness and preservation of the environment and its didactic-pedagogical sequence promoted progression in the visuomotor, motor, motor, playful, affective, and critical-reflexive aspects, for the promotion of the acquisition and strengthening of competencies and skills.

• RELAÇÃO ENTRE MEIO AMBIENTE E AS PANDEMIAS
  No final de 2019, era revelada uma das maiores pandemias da atualidade, com o poder de fechar cidades por inteiras. Esta se trata da Sars-cov-2, que tem disseminação muito rápida, sendo transmitida pelo ar. O coronavírus não é novidade para o mundo e o risco de pandemias já existia há muitos anos, por exemplo, o da epidemia de 2013, feito pela OMS (Organização mundial da saúde) quando já se alarmava sobre a potencialidade deste vírus causar surtos. Pandemias não são nenhuma novidade para humanidade, estando presentes em diversas épocas da história e neste trabalho, apresenta-se a ligação entre pandemias e distúrbios do meio ambiente natural, com ênfase nas zoonoses. Serão expostas, de forma breve, algumas pandemias e seus desdobramentos, apontando paralelos entre elas. O estudo foi realizado através de análises de artigos científicos, dentro do tema especificado em revistas com alto teor de confiabilidade buscando entender este fenômeno e como enfrentá-las. O artigo foi escrito enquanto o mundo atravessava a pandemia de Sars-cov-19 e foi evoluindo em conjunto com as descobertas feitas dia-dia pelo mundo científico. Foram definidas metas, como estudar as zoonoses e suas formas de transmissão, analisar o fator humano e como este impacta no meio e apontar soluções para resolução destes problemas. Concluiu-se com esta revisão bibliográfica que, quando o ser humano invade o meio ambiente natural e destrói as relações existentes neste local, podem surgir doenças transmitidas de animais ou do próprio meio, que podem ou não acarretar novas pandemias através de zoonoses.
• OS IMPACTOS SOCIOAMBIENTAIS CAUSADOS PELA EXIGÊNCIA DO CADASTRO AMBIENTAL RURAL AOS AGRICULTORES FAMILIARES DO ESTADO DO AMAZONAS EM 2019.
  As questões ambientais continuam na agenda de crescimento em todo o mundo. Grande parte das preocupações globais está voltada para a Amazônia, mesmo que deixe de lado todo o contingente humano que habita esse espaço, como fazem os agricultores familiares amazônicos. Normalmente, desconsidera-se que a conservação deste ecossistema depende essencialmente dos seres humanos que aqui vivem. Portanto, a gestão deste território deve criar e implementar mecanismos e instrumentos capazes de promover o desenvolvimento rural sustentável na região, congregando interesses sociais e ambientais, o que deve ser feito por meio de leis. Para essa convergência, foi criado o Cadastro Ambiental Rural (CAR) como instrumento de implementação de políticas públicas rurais sustentáveis. Este estudo investiga os impactos socioambientais causados pela exigência do CAR aos agricultores familiares residentes na zona rural do estado do Amazonas em 2019. Foram utilizados métodos hipotético-dedutivos e científico-tecnológicos, além de levantamentos bibliográficos, documentais e entrevistas com profissionais que trabalham no cadastramento desses agricultores. Os resultados mostraram que 1) as falhas de preenchimento dificultaram a validação do CAR e que, portanto, deve ser criado um procedimento operacional para viabilizar sua execução, 2) o grupo de agricultores familiares amazonenses é predominantemente composto por homens, casados, com baixa educação, posseiros e que desenvolvem atividades de subsistência, 3) a falta de licenciamento ambiental e a restrição de acesso aos recursos destinados ao crédito rural foram os impactos socioambientais significativos causados em 2019 e que 4) a implantação do procedimento operacional proposto neste estudo para registro do CAR pode amenizar os conflitos de sobreposição de cadastros cadastrados, o que beneficiará agricultores familiares e populações afins, guardiões dessas áreas. A conclusão reafirma que o caráter simplificado atribuído à legislação federal e estadual não foi suficiente para viabilizar o CAR para os agricultores familiares amazonenses em 2019 sem causarlhes impactos socioambientais significativos
