Anthropometric And Ergonomic Analysis Applied To An Industrial
Production Manual Insertion Line In The Electronics Segment Background: The principle of ergonomic work analysis is to identify and try to prevent possible illnesses that develop slowly due to repetitive movements, unfavorable postures, uncomfortable furniture and visual discomfort, resulting in loss of productivity for the company, employee dissatisfaction and increased costs. The work environment and unsuitable furniture can also lead to a reduction in productivity in companies, because if it is not adjusted to the biotypes it can lead to the occurrence of work-related illnesses. One of the great challenges of ergonomics applied to work is to design or adapt workstations and tools to the morphological diversity of the population. Accurate analysis of the various segments is carried out using anthropometric techniques, which is the study of the physical measurements of the human body. The aim of this research was to apply ergonomic work analysis to the production line of a company in the electrical and electronics sector in order to promote improvements in the workplace with a view to the quality of life, well-being and safety of employees. Materials and Methods: The study's methodology included a population survey of the company's biotypes by means of an anthropometric assessment; an analysis of the movements of the human body with an emphasis on the upper limbs according to the conditions of their workstation; the implementation of ergonomic concepts on the production line; the adaptation of workstations to employees; and finally the monitoring, follow-up and comparison of productivity results after the implementation of ergonomic improvements. To analyze the results of this research, a sample of 375 employees was carried out, focusing on the manual insertion production line. Results: The anthropometric analysis showed that there is a difference between the male and female biotypes. With females more concentrated around the average and males showing a greater tail of the distribution. After implementing the improvements, the ex-post analysis showed that the targets proposed by the company for productivity, quality and absenteeism were achieved, with averages of 780.2 units/hour, 281.4 pieces/million and 1.8%, respectively. Conclusion: The ergonomic work analysis identified the need to adapt, alter and change the company's workstations, starting with the equipment and extending to the posture of the employees working on the production lines. The combination of anthropometry and ergonomic analysis was the fundamental basis for innovation in the sectors, jobs, production process and work routine.

Analysis Of Energy Efficiency And Environmental Impacts With The New Inverter Air Conditioning Technology Air conditioning systems are known for their high energy consumption and the environmental impacts they can cause, especially with regard to greenhouse gas emissions. However, inverter air conditioning systems are a more advanced technology that can offer significant improvements in terms of energy efficiency and reduced environmental impacts. Inverter air conditioning systems use a variable speed compressor, which allows the unit to adjust the compressor speed to meet cooling or heating needs. This means that the compressor does not have to switch on and off continuously, which reduces energy consumption and increases system life. In addition, inverter air conditioning systems are designed to operate more quietly and produce less noise than conventional systems. In Brazil, where demand for air conditioning systems is high, the use of inverter air conditioning systems can have a significant impact on reducing energy consumption and greenhouse gas emissions. In addition, Brazilian authorities have implemented measures to encourage the adoption of energyefficient technologies, including energy efficiency labeling programs to help consumers identify the most efficient appliances. However, it is important to remember that the energy efficiency of an inverter air conditioning system depends on its proper installation and maintenance. It is necessary that the system be sized correctly for the space in which it will be installed and that a regular maintenance program be carried out to ensure that the system is operating efficiently. In summary, the use of inverter air conditioning systems in Brazil can offer significant benefits in terms of energy efficiency and reduced environmental impacts, especially when combined with government incentive measures and proper installation and maintenance practices. It is with these first fruits that this project will explore the need for technological changes for refrigeration systems, proving their efficiency both in terms of energy and the environment.

Manufacturing Outsourcing As A Strategy For Increasing Production Capacity And Reducing Production Costs This work addresses the increasing demand for smartphones in the electronics industry and the need for manufacturing expansion to keep up with this growth. Smartphones have become an integral part of society's routine, both for personal use and as a work tool. To meet this demand, outsourcing has been widely adopted as a strategy, aiming for cost optimization and improvements in business process efficiency. Several studies have analyzed the factors influencing the outsourcing decision, such as the degree of product or process standardization, the costs involved, and the correlation between companies and services provided. The article proposes an empirical outsourcing model for manufacturing in an electronics devices industry located in one of Brazil’s Industrial Hub, aiming to increase production capacity and reduce costs. The research seeks to contributeto studies on outsourcing as a business alternative and provides a model for business managers and researchers exploring this topic. The feasibility study and introduction of outsourcing are conducted through the action research method. The action research process is illustrated in main six stages: planning, data gathering, data analysis and action planning, implementation of actions, evaluation of results and report, and finally, continuous monitoring, which occurs simultaneously with the other activities in the cycle. In this paper, the proposed action research is applied in three main stages: searching for concepts, building an empirical methodology based on the specific needs of the company in question for outsourcing implementation, and implementing it in a real practical case, resulting in the evaluation of the outcomes and decision-making regarding the capacity of the contracted company to produce the products of the contracting company. The construction of an evaluation model for companies aiming to implement outsourcing, starting from the selection of possible third-party companies, evaluation criteria based on the needs of the contracting company, set-up of the production process in the chosen company, validation of the third process, and continuous monitoring of this new implemented process. This study serves as a model for companies seeking to apply outsourcing not only to peripheral areas but also to core activities, providing an alternative for business expansion and operational cost reduction

Education and Sustainability in the Curriculum of the Technical Course in Buildings: Implementation and Challenges Increasingly, humanity has established a predatory relationship with nature due to the consumerist and capitalist model of production. As a result of this lifestyle, humanity is rapidly approaching a scenario of environmental disaster. Teaching and learning how to take care of the world, how to care for the collective, how to reduce, recycle, and reuse should be themes addressed in schools in a relevant and effective way. This would not only raise awareness among students, but also among the entire faculty of educational institutions, the professionals who work in them, the community, society, and the world. Only through education will we be able to cultivate behaviors and habits consistent with sustainability. To achieve this, the curriculum needs to be restructured, allowing for an integrated approach to incorporate sustainability concepts and sustainable development with school knowledge and experiences. Considering that the disciplines of the Pedagogical Project Course (PPC) of the Integrated Technical Course in Buildings do not currently include the theme of sustainability, this work aims to identify and propose the inclusion of teaching sustainability concepts and sustainable development in the syllabi of technical courses in the integrated modality in buildings within the civil construction area of the Federal Institute of Amazonas (IFAM).

Implementation Of The Zero Landfill Program In A Transformation Industry At PIM- Industrial Pole Of Manaus Background: This study was carried out with the objective of analyzing the feasibility of implementing the Landfill Program in a manufacturing industry located in the Industrial Pole of Manaus (PIM). The PIM is a major industrial region and presents a significant challenge with regard to waste management. In this context, the Zero Landfill Program emerges as a sustainable approach that seeks to reduce the sending of waste to landfills, encourage the reuse of materials and promote recycling, creating an economic cycle and inspiring other companies to adopt similar practices. Materials and methods: To achieve the proposed objectives, a case study was carried out in the manufacturing industry of Manaus. Based on the principles of the 3Rs (reduce, reuse and recycle), sustainable industrial waste management practices were developed. Actions were implemented to reduce the amount of waste generated in the production process, promoting awareness of the importance of reducing at source. In addition, procedures have been established for the reuse of materials whenever possible, seeking to extend their useful life cycle and minimize disposal. Recycling programs were also implemented, encouraging the transformation of waste into new products or raw materials. Results: The results obtained were promising. The Manaus plant was able to meet the necessary criteria to obtain certification in the Zero Landfill Program. This means that the company was able to significantly reduce the amount of waste sent to landfills, keeping this value below 1% of the total waste generated in the production process. In addition, the factory was able to take advantage of and recycle at least 3% of the waste, transforming it into energy through appropriate processes. Conclusion: Based on the results obtained in this study, it is possible to conclude that the implementation of the Landfill Program in a transformation industry in the Industrial Pole of Manaus is feasible and brings significant benefits in terms of environmental sustainability. The Manaus factory served as an example of good practices, encouraging other companies to adopt similar measures to reduce their environmental impact. However, for a deeper understanding of the subject, future studies are recommended. These studies may include expanding the analysis to other industries and regions, in order to verify the applicability of the Landfill Program in different contexts. In addition, it is important to carry out cost-benefit analyzes to assess the economic viability of these sustainable practices, as well as more comprehensive environmental impact assessments. It would also be interesting to investigate the perception of employees and the local community regarding the implemented changes, seeking to obtain valuable feedback.

Estimation Of The Unitary Cost Of The Square Meter Popular Housing In The City Of Manaus Based On The Most Important Inputs, Using Artificial Neural Networks Abstract: Civil construction is one of the most expressive sectors in the economy, development and employability in the national territory. It is considered one of the branches that demonstrates the expansion and wealth of a country, where social housing is directly linked to socioeconomic development. According to the IBGE, in 2020, Manaus had 653,618 homes, of which 348,618 are classified as subnormal agglomerations, that is, stilt houses and unhealthy occupations and/or difficult to access. It can be said that one of the major obstacles to the construction of low-income housing is the lack of predictability of the behavior of costs during the execution of the work. This factor is even more pronounced in subdivisions and housing complexes, that is, in mass production, due to quantity. In order to mitigate these challenges, a tool was developed, based on the concepts of RNA -Artificial Neural Network, which compiles 2 civil construction price databases and predicts the cost of popular housing based on the value of the main inputs. This network seeks to estimate the cost per square meter of construction of popular housing in the city of Manaus. MATLAB® software was used, where data from the CUB and INCC databases were compiled. The inputs used were those contained in the so-called “basic batch”, recommended by the CUB. Quickly and practically without cost, the developed tool can predict the price of the square meter of popular housing, in the city of Manaus, from the stipulation of the inputs. RNA was able to present a very strong correlation in the sources of its sample space, thus demonstrating that the databases, despite presenting different data collection and treatment, in addition to being elaborated by different institutes, present compatibility in their databases, which is reflected in the veracity and reliability of the data collected and processed. After estimating several statistical indices, it is clearly noted that this is a tool that has proven to be efficient and safe for estimating future costs. Background: The final cost of a work is one of the determining factors for carrying it out, especially in the more popular classes, where money is scarcer and any financial estimation errors can make the completion of the building unfeasible. In Brazilian territory, there are databases that predict the cost for the present, but none that estimate the cost for the future. This study develops an RNA to simulate the future value of a popular building in the city of Manaus. Materials and Methods: In this study, two databases were used as a national recognition database: the CUB and the INCC. The reference values were extracted from the databases, in monthly cadence, during the period from July 2009 to May 2022, to obtain an arithmetic medium for each item, thus allowing RNA simulation to predict the value of the square meter of the house. Results: Values for: MSE, NRMSE, MAPE, SER, MAE, RMSE, Medium Percent Error, and Pearson Correlation. All show adequate and correlated results. However, it can be stated that the most expressive result was the MSE, which was 91.14%, characterizing a well-adjusted RNA. Conclusion: The correlation between the data in the two databases was 91.14%, enabling the simulation of an artificial neural network with data from different sources and good accuracy.

Mobile technology to optimize the operational control of the entry of
national goods in the areas administered by suframa: vistoria 4.0 A Zona Franca de Manaus (ZFM) é uma área com incentivos fiscais e parafiscais criada para estimular o desenvolvimento econômico na região Amazônica. Em 2021, a região recebeu mais de 53 bilhões de reais em mercadorias (SUFRAMA, 2022), o que, juntamente com sua vasta extensão territorial e infraestrutura precária, apresenta desafios logísticos que dificultam a fiscalização e tornam a região propensa a fraudes fiscais, como o desvio de mercadorias e o uso indevido de incentivos fiscais. Essas práticas ilegais prejudicam a economia local e nacional e podem prejudicar a imagem da autarquia. O projeto é composto por três pilares: comercial, agropecuário e industrial (REY e JÚNIOR, 2019). Com isso em mente, este trabalho propõe um aplicativo que utiliza tecnologias de informação para aumentar a eficiência e segurança do processo de fiscalização de mercadorias. Dividiu-se os trabalhos em três etapas: Elicitação dos requisitos; Elaboração do protótipo; Levantamento dos pontos de função e estudo de viabilidade e o aplicativo utilizará tecnologias embarcadas, como a Optical Character Recognition (OCR) e a Geolocalização, permitindo que os próprios destinatários das mercadorias realizem o procedimento de vistoria física de forma segura. Foram elicitados os requisitos funcionais e não funcionais do aplicativo e as telas das interfaces foram elaboradas no software FIGMA. Também foi realizada uma análise do potencial ganho de produtividade do controle de mercadorias, onde foi verificado que apenas com medicamentos e veículos, foi possível aumentar a produtividade quantitativa das vistorias físicas em 7,5%, passando dos atuais 2,5% definidos como meta institucional para quase 10% do total dos valores das notas fiscais registradas na autarquia. Além de melhorar a eficiência do processo de fiscalização na ZFM, o aplicativo alcançará 100% da área de controle cobrindo todos os 157 municípios incentivados da região. Atualmente, apenas 11 cidades têm sedes administrativas e vistorias físicas (Suframa, 2022). Foi constatado que o baixo investimento necessário para o desenvolvimento do aplicativo, em comparação com a contratação de servidores para realizar o mesmo número de vistorias físicas, é vantajoso pela sua economicidade. A utilização de tecnologias da informação para fortalecer o controle de entrada de mercadorias é uma opção econômica, prática e sustentável que pode fortalecer o processo de fiscalização e minimizar os riscos de fraude.

Use of chirps satellite precipitation in the characterization of the franceses stream Basin, Manaus - State of Amazonas - Brazil The city of Manaus has numerous waterways in its urban perimeter, and, despite this, there is a shortage of measures aimed at protecting water resources that has generated occupations very close to the riverbeds. This work aims to characterize a watershed in an urban area of Manaus and map the areas subject to flooding around the Franceses Stream. The methodology applied involved obtaining topographic and thematic information such as morphology, geographical location, elevations, extent, area, level curves (water dividers) of the basin, obtained through georeferenced satellite images in a GIS environment.In addition, monthly satellite precipitation via the CHIRPS product was used for the calculations. The physical characteristics of the basin were determined using equations employed in hydrology. The results indicated that the Franceses Stream basin is not subject to major flooding, presenting the following characteristics: compactness coefficient Kc = 5.71; form factor Kf = 0.36; circularity index Ic = 0.03; drainage density Dd = 0.94km-1 . It was also found that, despite the intense occupation, there is preserved vegetation within the basin. It was concluded that the precipitation estimated by CHIRPS is efficient because it has a larger coverage, and that knowing the characteristics of watersheds in urban environments is of great importance to subsidize intervention measures and planning policies that ensure the protection of water resources and minimize inconvenience to the population. It was also found that the use of GIS is an important tool for analyzing information in hydrological studies, and that it needs to become an increasingly applied tool in urban management, so that the knowledge obtained can be used to obtain better environmental and social conditions.

RAIN PREDICTION MODEL USING ARTIFICIAL NEURAL NETWORKS Precipitation is important in maintaining the environment and life of living beings. Through their studies and increasingly accurate forecasts, we can reduce the impacts related to floods, environmental disasters, and losses in the agricultural and tourism sectors. However, climate change has made the analysis of this variable difficult. In this article we will present an hourly rain forecast model using Artificial Neural Networks, using the information on instantaneous, maximum and minimum temperature, relative humidity, wind, and precipitation through the automatic weather stations of the Instituto Nacional de Meteorologia, located in the city from Manaus/AM. First, a study was carried out to determine the network architecture best suited to the data set. Numerous combinations between the training and transfer functions were performed until finding the functions that presented the best error values. The predictions made with the model showed satisfactory results, showing that the model was able to reproduce the same behavior of the precipitation observed for the predicted day, presenting practically the same totals, especially on the rainiest days. On the other hand, in cases where the observed showed a characteristic of convective precipitation, the model was not able to capture the intensity, which shows that it must be tested with other atmospheric variables.

APPLICATION OF FUZZY LOGIC FOR DECISION-MAKING IN THE CRITERIA FOR ALLOCATION AND DISTRIBUTION OF INDUSTRIAL COSTS. Background: Industries are increasingly specializing in the financial and production sector, aided by general accounting and, especially, cost accounting. Even increasing the degree of complexity of specialized employees, cost accounting in relation to its apportionment criteria is always a challenge. Companies find it very difficult to correctly determine the unit cost of the product or service being offered. And it is precisely at this moment that cost accounting proves to be useful and indispensable. Cost apportionment is one of the branches of industrial accounting and it is a subject that seems to be simple to understand, however, it becomes more complex during your daily practices. This work aims to develop a classification model for decision making based on Fuzzy Logic for diagnosing production performance with a focus on financial improvement based on the optimization of cost apportionment. In this context, the work is justified by pointing out a new perspective of analysis through production and financial indicators implemented in a Fuzzy interference model with the objective of optimizing the apportionment criteria and proposing financial improvements. Materials and Methods: The Methodological Process of the research was developed in three phases: 1. Identification of Economic and Production Indicators; 2. Modeling of the Fuzzy “Inference” System; 3. Proposed Model Experiment. Each phase consists of three stages until reaching the results obtained from the research. The proposed Fuzzy system was able to show the different performance results when simulated with the different conditions of the input variables and which the projected performance classification could be defined. Results: The model resulted in 576 inference rules for analysis. In one of these analyses, I specify analysis 291 according to table 8 of this article, considering the indicator of Overall Labor Effectiveness “Good”, Overall Equipment Effectiveness “Bad”, Contribution Margin “Good”, Breakeven Point “Good” and Liquidity Current “Good”, the performance of the product is considered “Medium”. With a bad EGE, it is difficult to properly monitor production efficiency to a satisfactory degree, but you can maintain a standard production pace due to the good results of other indicators. Conclusion: In this way, the Fuzzy system helps to guide us in which costing method we should adjust the worked product so that it can generate profitability within the industry and better profit margin, allowing a more critical analysis in internal decision-making.

FUZZY MODELING TO DEFINE CORROSIVITY POTENTIAL IN OIL PIPELINES In this work, a Fuzzy logic model was developed using the Fuzzy Logic Toolbox™ of the MATLAB® software, for monitoring the corrosivity potential in oil pipelines whose corrosion mechanism is predominantly by microbiological action. With the use of operational parameters, the model presents itself as an alternative to conventional monitoring methods, allowing to infer the corrosion rate in the pipeline, and therefore, the corrosivity potential. The model was applied to an oil pipeline and its results were compared with conventional monitoring methods. The analysis of the results concluded that the model can be used as a monitoring method for pipelines with those predominant corrosion mechanisms, helping to manage the integrity of oil pipelines.

IMPLEMENTATION OF ISO 50001 – ENERGY MANAGEMENT SYSTEM IN A FACTORY IN THE ELECTRICAL AND ELECTRONICS SECTOR: MULTI-CASE STUDY We know that a series of factors influence and determine the degree of competitiveness of an organization, especially those that value good environmental, social, and corporate governance practices. Of course, there are other themes for competitiveness to be obtained in all fields; however, the focus on the ESG issue is another indication of how much the theme “sustainability” has gained more and more relevance in the market and consequently in business. In fact, the environmental issue was cited as one of the main points of concern for today's society in the most recent edition of the Global Risks Report, by the World Economic Forum (WEF), which highlighted issues such as extreme weather events, failures in negotiations regarding climate, environmental damage, and loss of biodiversity as major threats. In addition to the environmental aspect, society has also shown itself to be increasingly concerned with social and governance values. Socially, it has become essential to ensure a diverse corporate environment. More transparency and honesty in business began to be valued. Thus, the three pillars of competitiveness are basically focused on: Environmental protection, social responsibility, and economic success (Governance). In order to achieve all pillars, it is necessary to comply with standards established for large leading organizations in the market, to meet standards, laws, and data protection. In this context, norms and rules are presented to companies that aim to maintain compliance with these in order to obtain increasingly required certifications. Within the context discussed above, this work deals specifically with the ISO 50001 Standard - Energy Management System, where a process is described that aims to scientifically record and analyze the events that occur during the processes of monitoring energy consumption by electrical equipment significant energy use (SEU) as part of the standard certification process. During the process, all tools applied to develop the work were used such as: Strategic Planning, PDCA, Swot Matrix, and Hoshin Plan. The need is detailed in the organizational strategic planning and continues to be deployed in the organization. As a final result, the objective is to obtain certification in the standard with the understanding and fulfillment of all the items in question within the planned period. This case study that portrays the certification process of an electronics company in the Energy Efficiency Management System standard is of fundamental importance for bringing results to the organization in terms of reducing energy consumption and impact on the environment, and for improvements arising. The methodology used in the company was based on the energy diagnosis of the organization and using the PDCA method. The objective of the article is also to demonstrate, at the end, the level of knowledge of employees for the development that involves Energy Management after the organization's certification, done through field research.
