Item A aplicação do Lean Six Sigma para aprimoramento da accountability nas decisões do Tribunal de Contas do Estado de Goiás(Universidade Federal de Goiás, 2023-09-28) Santiago, Leonardo de Guimarães; Bevilacqua, Solon; http://lattes.cnpq.br/4706313748524604; Bevilacqua, Solon; Nemirovsky, Gabriel Gualhanone; Luz, Bruno Batista de CarvalhoThe Brazilian Courts of Auditors are entities structured to supervise the application of public resources, report their findings to society, hold those involved responsible and contribute to the correction of improprieties through the decisions they issue. This study analyzed the process of formatting, storing and consulting the decisions of the Court of Auditors of the State of Goiás, with the objective of evaluating whether the Court achieves a quality standard capable of favoring internal efficiency in monitoring the provisions handed down and instrumentalizing their follow-up by society. To do so, we used the Lean Six Sigma methodology, combining statistical models for measuring variability with business process management techniques. The results show low performance in relation to the conformity expected by the institution itself, mainly due to the elaboration of procedural documents and data registration without automation support that induces the fulfillment of quality requirements, a circumstance also observed in other Courts of Accounts in the country, indicating that the procedures used in the diagnosis and in the proposal for improvement presented can contribute to the improvement of other members of the Brazilian external control system.Item Abordagem sustentável de consultoria integrada para aumento de produtividade em micro-pequenas empresas(Universidade Federal de Goiás, 2021-05-10) Valle, Éverton Fleury Victorino; Severino, Maico Roris; http://lattes.cnpq.br/2546008836929749; Severino, Maico Roris; Santos, Luciano Costa; Fonseca, Marcelo NunesIn an increasingly competitive scenario, companies that embrace sustainable practices have greater competitive advantages and contribute to society through sustainable development. Small and medium enterprises (SMEs) are an interesting object of study due to their peculiar behavior and the need for external assistance to implement practices of this nature. There is a vast international literature on the application of sustainable practices, but in a reduced universe when the focus is on SMEs, and especially when it comes to environmental consultancy and productivity for SMEs. Thus, the general objective of this research is to provide a sustainable integrated consulting approach to increase productivity in SMEs. Therefore, a bibliometric study was carried out to identify the main practices discussed in the literature, as well as barriers and drivers for their adoption. With the identification of these practices, an internal mapping of the SENAI Institute of Technology in Automation was carried out to diagnose the current situation and possibilities for implementing the practices used by the institution. Flowcharts were drawn, as well as an AS IS and TO BE proposal and a standardization of processes was defined for certain consulting services, detailed in three levels of implementation. Indirect gains were also highlighted. Finally, the tools were selected and defined to demonstrate their applicability in consulting methods. Among the solutions developed, the Sustainable Value Stream Map (SUS-VSM) and the General Environmental Effectiveness of Equipment (OEEE) stand out for immediate applications and the use of global indicators such as the Eco-indicator for future applications. Thus, this work has as its main contribution the demonstration of a sustainable and integrated approach to consulting for MSEs in Brazil, based on a case study.Item A administração da tecnologia e participação social como insumos para gestão democrática: o desenvolvimento do E-Gov e da E-Democracia(Universidade Federal de Goiás, 2016-09-29) Oliveira, Thadio Robledo Queiroz; Carvalho, Claudia Regina Rosal; http://lattes.cnpq.br/4883069832734425; Carvalho, Claudia Regina Rosal; http://lattes.cnpq.br/4883069832734425; Souza, Eliane Moreira Sá de; Castro, Sérgio Duarte deAt critical moments, societies have always sought to increase their autonomy and participation in opposition to the heteronomous forces. Such public expressions materialized in each historical epochs in different ways. Nowadays, technological developments and civic engagement in political issues enabled the deliberation and discussion of social affairs using electronic media and, therefore, enabled the omnipresence of public opinion. This dissertation studies the concepts of egovernment and e-democracy as democratic management tools and analyzes how they can be a possible solution to increase transparency in public policy management. Diagnoses the level of development of the above concepts in the Brazilian context through the analysis of the Brazilian legislative houses’ websites, through the study of eight models of maturity and by studying e-democratic platforms. To assist in the diagnosis, it is created and deployed an electronic channel for social participation named InterajoBrasil, a citizen-led interventionist platform of e-democracy, applied to the public debate on the “provisional measures” quoted in the Brazilian Senate. It is also demonstrated, in this research, other systems and e-democratic platforms applications cases, studying the theoretical and practical framework of the main concepts and tools involved. It is also pursued to evidence that there is a positive correlation between development of e-government indicators and indicators of government transparency, aiming conceptual basis to help drawing up an action plan. The action plan is addressed as an interventional proposal that seeks to improve the management of technology inputs, the use of e-government and e-democratic channels, with a view to strengthening democracy and social participation, bringing more transparency in public policy management.Item Alinhamento de estratégias de pós-graduação ao plano nacional de pós-graduação (PNPG) e ao plano nacional de educação (PNE): ações na Universidade Federal de Goiás(Universidade Federal de Goiás, 2016-09-30) Arantes, Lara Izabella Tosta; Sousa, Eliane Moreira Sá de; http://lattes.cnpq.br/4454182958023791; Carvalho, Claudia Regina Rosal; http://lattes.cnpq.br/4883069832734425; Carvalho, Claudia Regina Rosal; http://lattes.cnpq.br/4883069832734425; Souza, Eliane Moreira Sá de; http://lattes.cnpq.br/4454182958023791; Cruz, Alethéia Ferreira da; Costa Filho, Bento Alves daAnalyzes the situation of the graduate at the Federal University of Goiás, especially if the offer of programs and actions are in accordance with the guidelines and wider and strategic goals contained in PGNP (National Plan for Graduate Studies) and PNE ( National Education plan) in an attempt to get a holistic view of the university, pointing out all the directly influenced sectoral actions or indirectly by institutional graduate policy. The objective of this study is to analyze the alignment between the guidelines contained in the National Education Plan, National Plan for Graduate Studies and Institutional Development Plan at the Federal University of Goiás, observe the improvement points, making a judgment of what is being done today university, proposing a plan of action that will act contributing to the planning of graduate actions developed at UFG and thus contributing to the institutional advancement, consolidated the importance of improving graduate to the expansion and concept university.The methodology also was based on data extracted from analysis of Sucupira platform Capes. The results concluded in the action plan, through a diagnosis of the UFG performs successfully and stock missing or have points of improvements aimed at further harmonization of the expectations of the academic community, the guiding rules of MEC, CAPES and society with regard to educational and technological developmentItem Alocação de pessoas por competência em instituições federais de ensino superior: estudo na Universidade Federal de Goiás(Universidade Federal de Goiás, 2019-03-27) Souza, Vanessa Rocha de; Severino, Maico Roris; http://lattes.cnpq.br/2546008836929749; Severino, Maico Roris; Bevilacqua, Sólon; Chiariello, Caio Luís; Nogueira Neto, José de AraújoThe National Policy for Personnel Development, instituted through Decree No. 5,707 / 2006, brought to the Federal Institutions the great challenge of aligning people and their competencies with the strategies and objectives of the organizations. This research proposes alternatives to seek this alignment now of entering the server in the public service. Thus, it is expected to know the potential of the workforce to reduce the turnover of the employees' boards and to contribute to improve the conceptualization of the efficiency of the public service in the eyes of the society. This research aimed to develop a generic methodology for the allocation of servers in Federal Institutions of Higher Education (IFES) that is aligned with the Management by Competencies. A survey was carried out in one hundred and three IFES on the process of implementation of the Management by Competencies and the methods of allocation of the servers. Three institutions that stood out for including in their allocation processes interviews, curriculum analysis and competency mapping were used as benchmarking, in which it was possible to perform an analysis of the allocation practices used in these institutions and from the results obtained to propose a methodology of allocation. In addition, a diagnosis was made of the practices experienced by the Federal University of Goiás and later a report of suggestions for adaptations for the application of the methodology in the Institution. This research contributed to the organizations better understand the demands of Decree 5.707 / 2006 building more articulation between the theory and the practice experienced by these institutions. In addition, it is another tool for the management and allocation of its servers to fill the lack of appropriate methodologies and techniques for policy implementation.Item Análise do modelo de progressão na Assembleia Legislativa do estado de Goiás – impactos motivacionais(Universidade Federal de Goiás, 2021-11-19) Santos, Santiago Francisco Alves; Caldeira, Pedro Jorge Zany Pampulim Martins; http://lattes.cnpq.br/4110419521142450; Caldeira, Pedro Jorge Zany Pampulim Martins; Barbosa, Flavia Lorenne Sampaio; Amaral, Tatiana Gondim do; Costa, Hulda Silva Cedro daThe Brazilian public administration works with two concepts related to the career evolution of civil servants: progression and promotion. Public organizations adopt their own requirements for professional development, with, in general, remuneration increases for each standard or class achieved. Such incentives, however, should not be limited to financial aspects only when the intention is to influence the employees' motivation and consequently impact productivity. Focusing on the Legislative Assembly of the State of Goiás (ALEGO), this research addressed the career path to which permanent government employees are subject, as well as the models of professional evolution adopted by other Legislative Assemblies in the country for comparison purposes. The model conceived by ALEGO was also correlated with motivational theories. The general objective of the study was to investigate whether ALEGO’s professional development model influenced the motivation of employees and, if so, to assess whether positively or negatively. The study also found that the implementation of a new career path that considers individuality for motivational purposes does not violate constitutional principles. Descriptive research was developed, framed as a case study. Structured interviews with 12 permanent employees of ALEGO were carried out, which integrated precepts of various motivational theories. Currently, ALEGO only considers the temporal gap for professional advancement, not having or using metrics to measure the productivity of its employees. In the rest of the country, data obtained indicated the existence of legislative bodies that use a mixed system of progression/promotion, with a strong tendency towards the extinction of career paths that only consider length of service, opting in general for systems based on merit. The analysis of the career evolution system in face of motivational theories, through theoretical application according to the answers given by the interviewees, allowed the elucidation of gaps in the model adopted by ALEGO, which can prevent the servers from achieving maximum professional performance. Almost all employees interviewed (91.7%) were dissatisfied with the automatic progression and exclusively by length of service and, of these, all viewed positively systems considered more complete for professional development adopted in the rest of the country. As an intervention proposal, the remodeling of the current system of progression by length of service and the stipulation of goals to obtain an extra remuneration increase was idealized. The need for further technical studies to assess the project’s feasibility was verified not ruling out the indispensability of legislative approval.Item Análise Envoltória de Dados (DEA) como ferramenta para avaliação comparativa de desempenho das comarcas do Tribunal de Justiça de Goiás(Universidade Federal de Goiás, 2019-06-12) Moraes Junior, Daniel Caetano de; Fuchigami, Hélio Yochihiro; Fuchigami, Hélio Yochihiro; Monteiro, Waleska de Fátima; Caldeira, Pedro Jorge Zany Pampulim MartinsData Envelopment Analysis (DEA) is already a widely used tool in the comparison of efficiency among Brazilian Courts, being used by the National Justice Council (CNJ) in the Justice in Numbers program. However, the same is not so often the case when it comes to comparing the counties of a particular court. The objective of this work is to use the DEA as a tool to comparatively evaluate efficiency among the TJGO Counties making possible the identification of possible improvement points. During the selection phase of the variables, it was necessary to resort to several databases, spread by multiple boards, which ended up showing a weakness of the Strategic Management Secretariat (SGE), which is not to have a database unified approach aimed at better decision-making by the TJGO manager. This is evidenced by the lack of an internal methodology for comparing the performance of districts and departments, which in this point strengthens the importance of this work. Once the difficulty of meeting the initial set of variables was overcome, due to their plurality and in order to give more credibility to the chosen methodology, to apply a scientific criterion to select the most representative among the group of variables presented. For that, the technique called Multi-Criteria Combinatory by Scenarios was chosen, which was adequate, selecting a total of six variables before a set of eight. After selecting the variables, the output-oriented DEA methodology was applied in the Banker, Charnes and Cooper (BCC) variant, and the result was consistent with the initial objective of this study. There has also been a Decision Support Panel, where it is possible to identify which points can be improved in each Region so that they achieve maximum relative efficiency.Item Análise sobre a morosidade do poder Judiciário brasileiro e propostas de intervenção(Universidade Federal de Goiás, 2018-05-04) Costa, Anderson Yagi; Severino, Maico Roris; http://lattes.cnpq.br/2546008836929749; Severino, Maico Roris; Carvalho, Willer Luciano; Betanho, CristianeMorosity is the main problem of the Brazilian Judiciary and has affected it for more than a century. In spite of the importance of this problem, there is a scarcity of studies in the literature that analyze, in a scientific way and with methodology, the possible causes of the slowness and that propose viable and manageable solutions. This study aims to verify if certain reported causes actually contribute to the slowness and, thus, to propose a viable solution. The survey of the possible causes was carried out through a review of the literature and the analysis of satisfaction surveys conducted at the Goiás State Court of Justice (TJGO). After identifying 43 (fortythree) possible causes, the increase in demand and the lack of magistrates / servers were selected for an analysis. After the analysis, using a methodology imposed by the National Justice Council - CNJ, it was found that the current number of magistrates and servants of the TJGO is enough to give flow to the demand. Thus, the redistribution of the labor force was proposed as a way to better serve the lossmaking judicial units.Item Aplicação da Análise Envoltória de Dados (DEA) para avaliação de desempenho das unidades acadêmicas de uma universidade federal(Universidade Federal de Goiás, 2019-04-30) Melo, Hugo Marciano de; Fuchigami, Hélio Yochihiro; http://lattes.cnpq.br/3025165325162182; Fuchigami, Hélio Yochihiro; Fonseca, Marcelo Nunes; Caldeira, Pedro Jorge Zany Pampulim MartinsIn a context of political reforms, economic and financial crisis and criticism of the Public Administration, managers and civil servants are expected to respond to the demands of society with greater quality and efficiency. In the context of the Federal Institutions of Higher Education, greater efficiency will be noticed when its teaching, research and extension activities produce the maximum results using the minimum resources available. This research uses the DEA model, with the aid of the Multicri-teria Combinatorial for Scenarios Method for selection of variables, in order to obtain comparative efficiency between academic units of the UFG for the year 2017. As results, it was observed that the UFG operated with technical efficiency of 70.47%, but with an overall efficiency of only 54.84% and that among the 27 Academic Units analyzed, only two are efficient, three have productive inefficiency and the others have inefficiency pure and productive. It concludes that the adoption of the DEA technique in conjunction with other techniques for calculating performance and evaluating results emerges as important mechanisms for identifying failures or pos-sibilities for improvements in the internal dimensions of the institution.Item Aplicação de sistema fotovoltaico off-grid como backup de energia na zona rural - estudo de caso(Universidade Federal de Goiás, 2023-08-21) Silva, Fernando Carvalho Assunção da; Fonseca, Marcelo Nunes; http://lattes.cnpq.br/9285142449945121; Belchior, Fernando Nunes; http://lattes.cnpq.br/5823317463324641; Belchior, Fernando Nunes; Santos, Ivan Nunes; Rabelo, Diogo de Souza; Fonseca, Marcelo NunesThrough electrical energy, it is possible to operate machinery, generate heat, and transmit information. This energy is generated, transmitted, and distributed until final consumption. However, interruptions in the power supply pose obstacles, especially for producers located in the rural areas of the state of Goiás, within the concession area of the distributor EQUATORIAL-GO. These producers face losses due to spoiled stored food and the death of animals in breeding facilities. With the rise of distributed generation, consumers have been enabled to produce their own energy, thus becoming prosumer. This study conducts a case analysis on a rural property located in the municipality of Cezarina-GO, aiming to investigate the optimal solution for maintaining a consistent energy supply through alternative generation sources. Different scenarios are explored: 1) Grid Electricity + Backup Generator; 2) Grid Electricity + Off-Grid Photovoltaic System; and 3) Grid Electricity + Off-Grid Photovoltaic System + Batteries. Based on the energy demand of the location, equipment is sized for each scenario, and a financial analysis is performed using indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Discounted Payback Period, and Levelized Cost of Energy (LCOE). The analysis considers the main implementation and operational costs for each configuration under study. The results show that the scenario "Grid Electricity + Off-Grid Photovoltaic System + Batteries" exhibits the best feasibility among the analyzed solutions. Despite having an initial investment nine times higher than the more traditional "Grid Electricity + Backup Generator" scenario, it presents a higher negative NPV and a lower LCOE over a 30-year period. Lastly, through a sensitivity analysis, parameters related to the cost of diesel fuel (R$), electricity tariff (R$/kWh), battery bank cost (R$), and the number of power interruptions were modified. Similarly, the "Grid Electricity + Off-Grid Photovoltaic System + Batteries" scenario remained the most viable for the first three analyzed parameters, while the "Grid Electricity + Backup Generator" scenario became more viable only when the number of power interruptions was reduced.Item Aplicação do conceito Internet das Coisas (IoT) e plataformas open source para monitoramento de painéis elétricos de baixa tensão(Universidade Federal de Goiás, 2023-03-14) Artur, Matheus Damaceno; Rabelo, Diogo de Souza; http://lattes.cnpq.br/2038840725490529; Belchior, Fernando Nunes; http://lattes.cnpq.br/5823317463324641; Belchior, Fernando Nunes; Guimarães, Marco Paulo; Francisco, Roberto da Piedade; Rabelo, Diogo de SouzaIn an increasingly dynamic, complex and competitive market, proper maintenance strategy and maintenance actions are essential for companies to keep their processes and equipment operating safely and reliably, to meet quality requirements and lower overall costs. In this scenario, the implementation of machine condition monitoring solutions plays an important role, and this process is currently considered one of the main levers in global performance research. Inserted in this context, the present work aims to develop a low-cost prototype with the application of an ESP32 microcontroller, open-source software platforms and the concept of IoT (Internet of Things) to cover the functionality of data collection and monitoring of electrical quantities and environmental aspects of an electrical panel in continuous time. Additionally, the use of the Big Data concept for data processing is foreseen, and the construction of a model that generates alerts and provides subsidies for health prognosis, implementation of maintenance/performance indicators and failure prediction. This solution is expected to help companies implement a Condition Based Maintenance (CBM) strategy, make more assertive decisions in maintenance actions, reduce costs in corrective interventions and point out ways for asset management to be more efficient. At first, a prototype was developed with a total cost of US$ 155.99, tests and calibration of the sensors were carried out in the laboratory. Finally, the solution in an industrial environment was applied, in which the following variables were monitored: ambient temperature, relative air humidity, dew point and barometric pressure inside the panel, opening/closing status of the doors of the Motor Control Center (MCC), temperature and operating status of a circuit breaker and contactor, in addition to electrical currents and voltages of 2 motors of the primary wheat milling cylinder bank. The merit of the work can be attributed to the possibility of applying Industry 4.0 concepts to solve real problems and the high potential for scalability.Item Autoavaliação institucional: proposições e evidências avaliativas para a pós-graduação da UFG(Universidade Federal de Goiás, 2023-05-31) Santos, Steffany Paula Morais dos; Araújo, Paulo Henrique Cirino; http://lattes.cnpq.br/5611371794712864; Araújo, Paulo Henrique Cirino; Roriz Junior, Marcos Paulino; Nemirovsky, Gabriel Gualhanone; Macedo, Larissa MatudaIn the last decades, the accelerated growth of Higher Education Institutions (HEI) boosted the creation of methods to evaluate them, which culminated, in 2004, in the conception of the SINAES Law. However, after 19 years of this law, there are still members of the institutions who are not satisfactorily included in the evaluation process. This is the case of students and professors of postgraduate programs who, despite being important sources of evidence on institutional development, have not had effective participation in institutional evaluations. To minimize this gap in the self-assessment processes in HEIs, this study proposed the development of an exclusive and unprecedented assessment instrument for postgraduate studies at the Federal University of Goiás (UFG). The general objective was to assess which factors are decisive, from the perspective of postgraduate students, for the development of the institution and its postgraduate programs. The social and academic contribution of this research is direct on its scientific field, since there is a lack of evaluative instruments and scientific research aimed at postgraduate studies. In the empirical field, the results obtained may help the UFG's Institutional Development Plan and other improvement plans. There is also the intention of contributing to future researchers and other institutions that want to implement evaluation at the postgraduate level. The methodology used was consist of bibliographic and documentary analysis, based on recent scientific texts and federal and institutional legislation. A case study of the self-assessment reports of the main HEIs in the country was also be carried out, in order to verify how the postgraduate assessment is carried out. Finally, through semi-structured interview techniques, the postgraduate evaluation questionnaire was prepared. Based on the analysis of the main results obtained, points that need improvement were identified, such as teaching and evaluation methodologies, the pedagogical project, and the planning of graduate programs, as well as infrastructure in general. Additionally, actions need to be taken to encourage scientific and technical production, extension activities, artistic production, and activities that value diversity. Finally, a proposal for institutional intervention was created, with solutions for the short, medium, and long term, depending on the actions that the administration will need to implement.Item Avaliação da satisfação do usuário de telefonia móvel da região Centro-Oeste por meio da modelagem de equações estruturais(Universidade Federal de Goiás, 2023-10-24) Oliveira, Juliane de Sousa; Santos Neto, Agenor Sousa; http://lattes.cnpq.br/6615964725213306; Soares, Júlio Cesar Valandro; http://lattes.cnpq.br/9557844115914458; Soares, Júlio Cesar Valandro; Santos Neto, Agenor Sousa; Almeida, Tiago dos Santos; Duarte, Márcio AntônioIn order to maintain competitiveness and profitability, telephone companies seek indices that assess customer satisfaction. Understanding the level of consumer satisfaction regarding the use of mobile phone services is essential, since this type of communication provides ease and is present in the majority of the population. This work aims to present the main factors that impact on mobile telephony user satisfaction in the Midwest Region. This research was developed with the aid of the questionnaire carried out by Anatel. The questions contained in the questionnaire were grouped into the following constructs: Perceived Quality, Expectations, Perceived Value and Global Satisfaction. Structural Equation Modeling was used to assess consumer satisfaction in the Federal District, State of Goiás, State of Mato Grosso and State of Mato Grosso do Sul. Each location got different results. For the Federal District, of the six hypotheses analyzed, two were rejected. For the State of Goiás, of the six hypotheses analyzed, two were also rejected. For the State of Mato Grosso of the six hypotheses tested, only one hypothesis was rejected. The State that obtained the highest number of rejections of the hypotheses was the State of Mato Grosso do Sul, of the six hypotheses analyzed, three were rejected. Of all the hypotheses analyzed, the customer expectation factor proved to be significant and positive in the perceived quality and value perceived by the consumer.Item Benefícios e desafios da auditoria baseada em riscos: proposta de implantação no Instituto Federal Goiano(Universidade Federal de Goiás, 2016-09-10) Brito, Guilherme Caetano; Pimenta, Daiana Paula; http://lattes.cnpq.br/9039708494014835; Pimenta, Daiana Paula; http://lattes.cnpq.br/9039708494014835; Carvalho, Claudia Regina Rosal; Campos, Flávia RezendeThe brazilian public administration has undergone several renovations in order to modernize the management. The latest reform, called Management Reform, innovated there instituit elements focused on the search for efficiency, results based management and the descentralization of activities. As a consequence, the internal control stopped focusing on the formalismo of the acts and directed its activities, in a decentralized manner trough internal audit units, for evaluation the achievement of objectives and risk management of public organizations. The audits from the perspectiva of risks is still a new topic in the public sector and was regulated only in 2015. Under the Ministry of Education there are federal institutions of higher education (FIHE) that adopt the risk-based audit (RBA) methodology for some years, however, there are no studies on the impacts of adoption of the methodology, or even on the best way to develop the implementation process. The objective of this study is to identify the benefits and challenges in the implementation of RBA in FIHE and propose an action plan for implementation RBA at the Instituto Federal Goiano (IF Goiano). Data were obtained through a questionnaire applied to internal auditors of FIHE and statiscally treated using fator analysis technque to extract factors taht represent groups of benefits and challenges in the implementation of RBA. They were extracted two factors that represent benefits and three factors that represent challenges in the implementation of RBA, especially the challenge of existence of inadequate risk management structure in the organization. Finally, it proposed na action plan for implementation of ABR in IF Goiano, containing actions to overcome the challenges previously identified.Item Caracterização tribológica das lâminas de corte de trituradores utilizados no processo de tratamento de resíduos sólido(Universidade Federal de Goiás, 2023-12-18) Souza, Willian Martins; Gonçalves Junior, José Lúcio; http://lattes.cnpq.br/2092647779902026; Bertholdi, Jonas; http://lattes.cnpq.br/0445297015533619; Bertholdi, Jonas; Troysi, Fernanda Christina Teotonio Dias; Ferreira Filho, DemóstenesIn Brazil, changes in production processes are observed due to environmental and social factors, which have as their biggest consequence the increase in the generation of solid waste. Because of these changes, it is essential to improve the efficiency of solid waste treatment processes, Thus, this work seeks to compare in laboratory tests the wear resistance of the cutting blades used in a solid waste crusher in the city of Aparecida de Goiânia, after application of different materials that can be used in the manufacture of the component, since the main problem presented was the loss in productivity in the treatment of waste due to wear of components of the crusher. After collecting a sample of cutting blade was identified through the study of Scanning Electron Microscopy (SEM) with Secondary Electrons (SE) and Backscattered Electrons (ERE), and also with Energy Dispersive Spectroscopy (EDS) that the type of wear preponderant in the tribological pair is the abrasive. From this premise, the laboratory experiment chosen was the rubber wheel wear test, because it is the method that best fits the system wear mechanisms, the same validated according to ASTM G-65. For the rubber wheel wear test were performed using samples of SAE 1060 steel and SAE 410 stainless steel heat treated. The studies demonstrated that it is not feasible to change the material used in the manufacture of the component, since the wear rates of the SAE 410D stainless steel samples were 55% higher than that of the samples that reproduce the condition of the cutting blade. This analysis is not limited only to one field, and can be extended to other sectors, using tribology as a reference, seeking to contribute to the academic production of production engineering, improving solid waste treatment operations.Item Clima, cultura e teoria do Stakeholder: proposta de um plano de capacitação para o Poder Judiciário do Estado de Goiás(Universidade Federal de Goiás, 2019-06-15) Chaves, Leandra Vilela Rodrigues; Vieira Júnior, Eliseu Machado; http://lattes.cnpq.br/8124167890774604; Vieira Júnior, Eliseu Machado; Almeida, Vera Luci de; Costa Filho, Bento Alves daThe objective of this study was the development of a Training Plan Proposal for the employees of the Judicial Branch of the State of Goiás, based on the identification of the main elements of organizational climate and culture, training and Stakeholder Theory, necessary for the accomplishment of the institucional mission, specially related to the agility, efficiency and effectiveness of jurisdictional activity. It was possible, through the application of the research instrument, identify sensitive areas to the demand for training and improvement actions. The importance of the study is substantiated by the evidence that continuous training actions have a positive impact on the improvement of public service, especially considering that the number of claims made by users regarding the deficiency of judicial services has generally increased. The result of the work demonstrated a strong identification of the employees with the Institution, an extremely favorable circumstance for the implementation of organizational changes, through training actions. On the other hand, the fragility in the use of technical criteria for the size of the workforce and in the definition of managerial positions has been revealed, which may compromise the achievement of the organizational objectives. The conclusion of the study is that aspects related to the behavior of employees and interpersonal relations, can not be neglected when the focus is the accomplishment of institucional mission. Also a process of evaluation of the training actions should be implemented in order to measure the effectiveness of what has been done. It is suggested, for future work, the replication of the methodology to other organs of the Judiciary and other Powers, as well as studies on the budget for training, in the context of the PJEG, in order to evaluate the efficiency of training actions, under this approach.Item Comparativo entre a geração fotovoltaica em aplicações utilizando inversores de string e microinversores(Universidade Federal de Goiás, 2023-02-01) Ginu, Ygor Ferreira; Ribeiro, Paulo Fernando; http://lattes.cnpq.br/2049448948386214; Belchior, Fernando Nunes; http://lattes.cnpq.br/5823317463324641; Belchior, Fernando Nunes; Bertholdi, Jonas; Ribeiro, Paulo Fernando; Domingos, José LuisIn terms of Brazil's Internal Energy Supply (OIE), there was a significant increase in the total available, registering an increase of 4.5% from 2020 to 2021, a value close to the GDP growth. For the Electricity Matrix there is an increase in domestic supply of 3.9% compared to 2020, but with a slight decrease in the participation of renewable energy sources, influenced mainly by the decline in supply of hydroelectric power. However, the growing use of biodiesel and wind and solar sources contributed to the Brazilian Energy Matrix reaching the renewable energy level of 44.7%, surpassing most of the other countries around the world. Solar photovoltaic generation is responsible for 5.5% of this share and has reached a gross generation volume of 16.8 TWh in 2021, representing an advance of 55.9%. Consequently, there is a race for the technological development of photovoltaic generation, especially the efficiency of solar modules and inverters. Micro inverters are gaining prominence for promoting an increase in the generation of electrical energy, by being able to reduce generation losses due to shading effects, orientation differences and mismatch losses because they can control, individually, the energy extracted from each module, however there is still a dominance of string inverter technology in residential applications. This paper aims to compare the two inverter technologies through actual yield data from monitoring the photovoltaic modules in 06 consumer units with microinverters in operation. The data is collected from the online monitoring platform and used to compose the generation if a string inverter with compatible commercial power was used, considering the conversion efficiencies for each technology. The technical and economic feasibility of the scenarios is performed by the main evaluation indexes. It was observed that the most influential factor in the analyses were the intrinsic losses of the photovoltaic systems, due to the inclinations of the modules, shading and differences in the yields of the inverters and microinverters increasing the attractiveness of the microinverter. The ID-05 plant presented the best results for the real layout, precisely because it presents a totally clipped topology, with different orientations, inclinations and suffering losses due to partial shading. The increase in the rated power of the plant has less influence than the technical losses when analyzing the financial return on investment, i.e., for cases with few losses factors the generation of the string inverters and the microinverters are similar, increasing the payback time of the investment.Item Compras públicas inteligentes: um modelo de análise estratégica para a gestão das compras públicas – estudo de caso do instituto do meio ambiente e dos recursos hídricos do distrito federal(Universidade Federal de Goiás, 2016-09-29) Terra, Antonio Carlos Paim; Machado Júnior, Eliseu Vieira; http://lattes.cnpq.br/8124167890774604; Machado Júnior, Eliseu Vieira; http://lattes.cnpq.br/8124167890774604; Severino, Maico Roris; Nogueira Neto, JoséPublic procurement constitute one of the most sensitive and important areas of logistics management that drives the Public Administration. Considering the theme of estimates of public procurement, expanded under the new paradigm that embraces purchasing activity, this paper aims to propose a strategic analysis model of government procurement activity, built from the concept intelligent public procurement - CPI . The concept of CPI considers a multidimensional view of public procurement activity, crafted from five dimensions: sustainability, innovation, legal frameworks, governance and efficiency. The purchasing management cycle is approached from the PDCA circuit, divided between the stages of planning, execution (operation), control and corrective actions. After modeling, application of the model (map) strategic in the Instituto do Meio Ambiente e dos Recursos Hídricos do Distrito Federal was held, making a diagnosis and proposing intervention measures aimed at improving the public procurement activities of the Institution.Item Desempenho do Sistema de Registro de Preços nas licitações praticadas pelo Poder Executivo do Distrito Federal(Universidade Federal de Goiás, 2016-10-03) Silva, Alan Carlos Cavalcante da; Cruz, Alethéia Ferreira da; http://lattes.cnpq.br/4696821747588199; Souza, Eliane Moreira Sá de; http://lattes.cnpq.br/4454182958023791; Souza, Eliane Moreira Sá de; Cruz, Alethéia Ferreira da; Carvalho, Claudia Reginal Rosal; Mello, Simone Portella Teixeira deThe Public Sector Management boosts the society development, using the taxes revenues to support the public policies. The Price Register System aims the wishes for the modernization provided by the Constitution. The study analyzes the Biddings and Biddings with Price Register System while the 2014 year. This works will develop strategies to enlarge the public sector performance in the state of Distrito Federal. The methodology provides a applied research. The research method aim detail aspects for the purchases, identifying the main factors for a good performance by a management diagnosis. The diagnosis found the number of common Biddings was bigger in the number of cases and about the value spending than the Biddings with Price Register System, and prioritized low price acquisitions of common goods. The proposal of action plan try finds a based strategy of a Permanent Forum for purchase planning.Item Desenvolvimento de sistema de indicadores para a gestão da manutenção de edifício público(Universidade Federal de Goiás, 2018-06-07) Guimarães , Gedson Barros; Almeida , Cristiano Farias; http://lattes.cnpq.br/9848560935338784; Almeida , Cristiano Farias; http://lattes.cnpq.br/9848560935338784; Pimenta , Daiana Paula; Souza , Eliane Moreira Sá de; Mello , Simone Portella Teixeira dePublic buildings are used by millions of people every day throughout Brazil. The public administration must ensure the proper management and operation of these essential devices for the full exercise of rights. Citizens, including servants and employees, need public buildings in keeping with the requirements of Brazilian technical standardization, rationality and efficiency, since they all contribute in the form of taxes to keep them functioning. The aim of this research was the development of a system of indicators to monitor the performance and efficiency of the maintenance of the systems that make up a public building. So, a system was made up of three indicators that monitor: annual maintenance expenditure, building performance and maintenance efficiency. The pre-test of these indicators in a public agency pointed to a reduction in annual maintenance expenditure between 2014 and 2016, but the performance of the building also declined, approaching its condition limit. This was confirmed by the MEI indicator, which was below the desirable number. Finally, it is presumed that such a joint can base decision making around government logistics or, precisely, administration of public buildings, as well as improve planning and budgeting in Public Administration.
