• 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.

• 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.
• KNOWLEDGE OF MANAGEMENT OF HEALTH WASTE IN COVID-19 FOR ENVIRONMENTAL IMPACT
  The pandemic due to COVID-19 has been shaping the healthcare landscape, mainly due to the amount of Health Service Waste (RSS) that is being produced. Understanding how these SSR are managed and how health professionals are involved in this process can provide a better understanding of how this knowledge directly impacts the better management of the SSR itself, as well as the reduction of environmental impacts from this flow. The objective of the study is to evaluate the knowledge of health professionals on waste management in time of COVID-19. An exploratory, descriptive, cross-sectional, observational study was conducted with 55 health professionals, working in a public hospital in Manaus – Amazonas - Brazil. Were included subjects over 18 years old, working in an institution that dealt with confirmed cases of COVID-19. The instruments used in the data collection were: Questionnaire defining the profile of the participants; Questionnaire evaluating basic knowledge about waste management of health services. The results indicated that the institution of interest has a protocol for the management of residues contaminated by COVID-19 as reported by 50 participants (90.9%), but most do not know what the Health Services Waste Management Plan (56.4%) is, not received training on SRHS (69.1%), not knowing how to classify without difficulty which are the Health Service Residues (54.5%), even performing invasive procedures (87.3%). Even with the increase in demand for health services during the COVID-19 pandemic, training and knowledge on how to manage the waste from these services did not follow the same growth
• METHODOLOGY FOR IMPLEMENTING A PHOTOVOLTAIC PLANT IN A SMALL FOOD INDUSTRY
  O aprender é uma arte, até Brazil needs to increase the supply of sustainable and renewable energy such as solar and wind, especially in the northern region, where it has the highest electricity tariff in the country. The region is distinguished from other regions of the country by the existence of several isolated systems, most of them of small size with low reliability and quality of services with very high costs, in view of the need for thermal generation using diesel and fuel oil, as amount represents about 92% of all the fuel planned to be used in Brazil in the generation of thermoelectric energy, indicating a fuel cost in 2021 that exceeds R$ 2 billion reais, which is largely exceeded by the transfers of resources obtained through the Fossil Fuel Consumption Account (CCC). This work aims to develop a methodology for the production of on-grid photovoltaic energy in order to be integrated into the utility grid as a reference in energy generation. It is a great alternative to reduce electricity consumption, and Brazil has the necessary conditions to take advantage of such technologies. However, this strategic action must be integrated, in order to develop society in the economic, social and environmental areas. The development of the work provided the generation of economic, technical and environmental results on the use of solar energy in regions that have high energy generation costs, in this way we train the techniques and structures to benefit, including small industries and businesses with a capture of energy resources. The general objective is to evaluate the results of the implementation of a 40 Kwp Solar Energy on-grid photovoltaic system at Empacotadora Amazonas, in order to reduce operating costs and environmental impacts.

• THE RELATION BETWEEN THE ENVIRONMENT AND PANDEMICS
  In late 2019, one of the biggest pandemics of our time, with the power to completely shut down cities, was revealed. This is Sars-cov-2, which spreads very quickly and is transmitted through the air. The Coronavirus is nothing new to the world and warnings about the risk of pandemics have existed for many years, such as that of the 2013 epidemic, made by the WHO (World Health Organization) at a time when there was already alarm about the potential of this virus to cause outbreaks. Pandemics are nothing new to humanity. They were present at different times in history, and this paper aims to present the link between pandemics and disturbances of the natural environment, with emphasis on zoonoses. Some pandemics and their consequences will be briefly exposed, pointing out parallels between them. The study was carried out through the analysis of scientific articles within the specified topic in journals with a high level of reliability, seeking to understand this phenomenon and how to face them. This paper was written while the world was going through the Sars-cov-19 pandemic and was evolving together with the discoveries made day by day by the scientific world. Goals were defined for this paper, such as studying zoonoses and their forms of transmission, analyzing the human factor and how it impacts the environment, and pointing out solutions to solve these problems. This literature review concludes that when humans invade the natural environment and destroy existing relationships in this place, diseases transmitted from animals or from the environment itself can arise, which may or may not cause new pandemics through zoonoses.
• THE DISPOSAL OF NEEDLES AND SYRINGES DURING THE COVID-19 PANDEMIC IN THE IRANDUBA HEALTH SYSTEM
  This paper aimed to develop evidence-based guidelines to make the disposal of syringes and needles, applied in vaccinations against Covid 19 safer and healthier in the UBS of the Health System of the Municipality of Iranduba, located in urban areas and non-riparian units. Thus, this research was based on a thorough process of observation, exclusively in the area of performance of the health management of the aforementioned municipality. The development process was carried out from an observational analysis, where the discarding of health supplies used in vaccinations against covid-019 in the year 2021 were realilized. In addition, a literature review was also performed for each of these steps. At the end of this arduous research, it was conclusively perceived the erroneous and harmful way in which the disposal of such solid waste was made, because these materials, soon after their use, were placed in a collection box, together with other sanitary inputs, perhaps the latter with the possibility of reuse or recycling, which would bring enormous risks to the workers of the UBS before the imminent probability of infection of covid-9.
• APPLICATION OF THE NONLINEAR AUTOREGRESSIVE MODEL WITH EXOGENOUS INPUTS FOR RIVER LEVEL FORECAST IN THE AMAZON
  The present work is justified by three basic lines that involve the problem of the theme, which are the use of Artificial Intelligence, the problem of floods in the Amazon and the issue of technology in favor of decision making. The environmental impacts caused by economic and social factors are problems portrayed in scenarios such as floods and ebbs of rivers, bringing up situations such as an increase in diseases, reduction of agricultural production in locations that depend on accurate geological control, in addition to the increase in erosive processes. in risk locations. Thus, the use of AI to predict the river level, which consequently can minimize problems arising from floods that cause an environmental impact, is highly possible, since when it is known in advance that an event is close to happening, decisions can be taken so that the impacts be smaller. This work models and applies NARX to forecast the river level in the Amazon with variables of easy access and implementation through the MATLAB software, in order to contribute with a forecast model capable of predicting a possible flood from the river level.
• ARTIFICIAL NEURAL NETWORKS FOR PREDICTING THE GENETATION OF ACETALDEHYDE IN PET RESIN IN THE PROCESS OF INJECTION OF PLASTIC PACKAGES
  The industrial production of preforms for the manufacture of PET bottles, during the plastic injection process, is essential to regulate the drying temperature of the PET resin, to control the generation of Acetaldehyde (ACH), which alters the flavor of carbonated or non-carbonated drinks, giving the drink a citrus flavor and putting in doubt the quality of packaged products. In this work, an Artificial Neural Network (ANN) of the Backpropagation type (Cascadeforwardnet) is specified to support the decisionmaking process in controlling the ideal drying temperature of the PET resin, allowing specialists to make the necessary temperature regulation decisions for the best performance by decreasing ACH levels. The materials and methods were applied according to the manufacturer's characteristics on the moisture in the PET resin grain, which may contain between 50 ppm and 100 ppm of ACH. Data were collected for the method analysis, according to temperatures and residence times used in the blow injection process in the manufacture of the bottle preform, the generation of ACH from the PET bottle after solid postcondensation stage reached residual ACH levels below (3-4) ppm, according to the desired specification, reaching levels below 1 ppm. The results found through the Computational Intelligence (IC) techniques applied by the ANNs, where they allowed the prediction of the ACH levels generated in the plastic injection process of the bottle packaging preform, allowing an effective management of the parameters of production, assisting in strategic decision making regarding the use of temperature control during the drying process of PET resin.
• ANALYSIS OF THE CURRENT MANAGEMENT OF HEALTH SERVICE WASTE: A CASE STUDY OF A UNIVERSITY HOSPITAL IN MANAUS/AM
  The health waste management activity, whose steps range from the identification of generation sites to the environmentally appropriate final disposal, requires appropriate planning, where each step of the process needs to be performed properly to ensure worker safety and mitigate the impacts generated to the environment allied to the hospital costs. Current legislation, such as: Law 6.938/81, which deals with the National Environmental Policy, Resolution 222/2018, Law 12.305/2010, which establishes the National Policy on Solid Waste (PNRS), among others, guide this process. The general purpose of this case study is to analyze the current process of management and treatment of waste from the health service of the Hospital Universitário Getúlio Vargas (HUGV). To achieve these results, a quantitative/qualitative, exploratory descriptive research was carried out on the HUGV Waste Management Plan. The information was collected through an Observational Roadmap of the Current Flow, based on the ANVISA Board Resolution 222/2018. Consistently, the results obtained showed that the hospital cost of waste treatment is directly related to the management of HSW. With this, it was concluded that the management process carried out in the hospital is not fully in accordance with the current legislation, and that this noncompliance results in the high cost for the treatment and final destination of the HSW, demonstrating the importance and the need to update the hospital's PGRSS (Health Services Waste Management Program). The research makes a relevant contribution to the HUGV with suggestions for proposals for improvements in the work of managing HSW.
• PROPOSED METHODOLOGY FOR ANALYSIS OF HARMONIC IMPACTS IN ELECTRICAL GRIDS USING DECISION TREE TECHNIQUE - PART 1
  The progressive use of power electronic devices, connected to the electrical system, has contributed to the increase of problems caused by harmonic disturbances in electrical networks. Thus, this work aims to develop a methodology to analyze the harmonic impacts on the electrical grids caused by non-linear loads with the use of the Decision Tree technique. The model used was the regression tree through the use of the Classification and Regression Tree (CART) algorithm, which relates the harmonic current of a non-linear load and the harmonic voltage at the common connection point of the electrical grid.
