The wind energy was already used as primary source of energy generation since before 1700 B.C, the old European civilizations used kinetic energy for sail, while windmills were used to help with farming tasks. At electricity generation, the wind energy is the primary source for the aerogenerators working, that convert some of this kinetic energy on electricity. With the technological progress, aerogenerators are modernizing with use of more efficient components, however, like any other machine, the wind turbines are subjects to the effects of time, that is, aging. The aging decreases the production capacity, increase the number of components fails, grow up the frequency of maintenance routines and increase the cost linked to the final product produced by these machines, the electricity. From that, this research was with objective to understand how the aging affect the performance decrease of aerogenerators, mapping linked factors at this effect. This study has realized was realized in 2 steps: the theoretical substantiation (1), constructed by a exploratory bibliographical review and a systematic bibliographical review, that, was with aim, mapping the related factors with performance decline at aging, followed by a factor’s validation (2), by one survey research, applied by two distinct questionnaires, one qualitative in a semi-structured interview and the other quantitative, this procedure made it possible to analyze whether the mapped factors and the constructed hypotheses were consistent with the functioning of these machines. A preliminary analysis of results allowed a construction of framework, tool that helps at grouping of mapped factors and the formulation of cause-and-effect hypotheses, the factors was grouped by similarities of your characteristics on dimensions, resulting on 5 dimensions: Climatic events, Installation site geography, Effectiveness of monitoring and predictions systems, Maintenance performance and aging, furthermore, the validation process show that the hypotheses has coherency, reinforcing the negative effects of aging on wind turbines and highlighting the impact of dimensions Climatic events and Installation site geography on the aggravation of aging and performance decline of machines.

The use of renewable resources is one of the most efficient means that several countries have adopted in order to mitigate climate change and environmental degradation due to the use of fossil fuels for electricity production. Wind energy, in particular, has grown significantly in the global electricity sector. However, the companies responsible for producing electricity face several challenges in the phase in which wind farms are in operation, since they are seeking greater productivity, quality and reliability in their operations in order to achieve high performance. The aim of this dissertation is to investigate the factors that influence the performance of onshore wind farms in the operation phase. The research is characterized as descriptive, of an applied nature and with a qualitative approach. The methodological procedure involved four stages: i) an exploratory literature review, ii) a systematic literature review (SBR) analyzing 70 documents on the topics of factors that influence the performance of wind farm operations and performance evaluation in the wind sector, iii) grouping the factors identified into dimensions, iv) drawing up a conceptual model based on the information collected in the theoretical research. As a result, 50 factors identified as conditioning performance in wind farm operations were systematized. The factors investigated were grouped by similarity into seven dimensions: Learning and growth (7); Techniques, tools and technologies (7); Meteorological and wind resource monitoring (8); Supply chain coordination (3); Organizational and operational efficiency (9); Financial management (8); Operation and maintenance performance (8). Finally, it can be concluded that the conceptual model proposed can be used to support strategic decision-making by managers in the wind sector, with a view to improving operational efficiency. Since identifying the causes that contribute to the good or bad functioning of wind farms is essential for mitigating possible problems that could hinder the performance of these enterprises.

This research aims to propose a methodology for choosing specialties that will integrate the own network of a health insurance company located in the city of Natal, state of Rio Grande do Norte. Private health care plans are seen by the population as a complement to the services offered by the Unified Health System (SUS), coexisting with this public service. Considering that the public sector is the target of numerous criticisms due to its inefficiency, private health care plans expand their share of the national market. Although a significant portion of the population accesses private health services, the sector still operates with a deficit of R$ 21 billion, which raises concerns about spending control and revenue generation. As one of the strategies adopted to maintain its services, the offer of health promotion programs and co-payment stand out. In addition to these strategies, verticalization is also pointed out as an alternative to reduce the fragmentation of services and reduce operating costs. The financial analyses linked to vertical integration point to savings in resources for companies, but only economic aspects are considered, without examining the multiple other characteristics of the problem, such as perceived quality aspects or consultation time. For a decision with several attributes, it’s necessary to consider several aspects beyond the financial analysis, including the subjectivity of the decisionmaker of choosing which medical specialties to bring to the own network. In the case of highly complex health problems, one of the tools used with considerable acceptance is multi-criteria decision analysis. Considering that decisions in the health area involve the confrontation between multiple objectives, and knowing that the criteria used in health evaluation have profound ethical implications, decision analysis allows the investigation of these objectives and criteria in the light of possible conflicts between multiple stakeholders. For this analysis, it is suggested the combined use of Value-Focused Thinking with the FITradeoff decision support method, in order to obtain a hierarchization of the medical specialties suitable to be contracted for own network.

Adverse events (AEs) are increasingly at the center of public health policy concerns around the world, as this type of occurrence is not rare and has affected many patients. In Brazil, from 2006 to 2022, 1,783 AEs related to surgical interventions were reported, with over 92% of these events classified as higher risk to the patient (classes III and IV), according to ANVISA. In Rio Grande do Norte, from 2013 to 2022, AEs due to surgical interventions accounted for 1.92% of the total notifications. Faced with the rise of the surgeries AEs, the World Health Organization (WHO) launched the second Global Challenge at the Patient Safety (PS) in 2008, with the theme “Safe Surgeries Save Lives”, aimed at the safety of surgical care. The overall objective of this study is to analyze the relationship between constraints and incidental variabilities and the occurrence of adverse events in patients during surgical processes at a public trauma hospital, the strategies adopted and the regulations carried out by nursing technicians to prevent adverse events or mitigate their impacts. Methodologically, bibliographic research, document analysis and field research were conducted. For field research, the situated and participatory method of Ergonomic Work Analysis (EWA) was used, through which interactional and observational techniques were applied, assisted by photographic and filming records, focusing on the nursing technician's activity during the surgical assistance process. This approach allowed to identify the following evidence related to the nursing technician's activity (surgical scrub nurse and operating room circulating nurse) in providing surgical assistance, among others: a ) activity determinants: lack of training in PS, lack of maintenance and replacement of equipment/ instruments, shortage of professionals, ineffective or absent communication; b) physical constraints: difficulty in transporting stretchers and hospital beds due to the existence of some floors with cracks, in addition to the risk of accidents involving the patient and the professional; stretchers and hospital beds with damaged castors and protective bars, requiring greater use of force by professionals and posing a risk of patients falls, as well as torn mattresses with damaged foam, causing discomfort to the patient; c) temporal constraint: difficulty for professionals to take breaks from work due to the high demand of patients in the surgical center (SC); d) incidental variabilities: breakage of the anesthesia cart, surgical table and other equipment during surgeries, causing surgical delays or the need for rescue ventilation with an Ambu; old, worn and damaged surgical instruments, hindering surgical instrumentation, which causes surgical delays and potentially prolonging anesthesia time. To ensure the efficiency of the activity and prevent AEs and mitigate their harm, technicians constantly make adjustments to the activity, employing strategies and actions, among others: fixing the protective bars of hospital stretchers with bandages to avoid patient fall; placing cardboard support below the stretcher mattress to make it more comfortable and avoid pressure injuries; opening other surgical boxes to find better surgical instruments to the surgeries. Based on the findings, the following measures were recommended to prevent and/or mitigate the risks of AEs in surgical patients, among others: use of the checklist or safe surgery verification list; establish effective intersectoral and interprofessional communication; acquire new or better-maintained stretchers and hospital beds to facilitate patient transportation and transfer; expand the nursing staff, reducing the physical and mental burden on professionals with turnover in surgeries. Therefore, it is concluded that there is a need to implement improvements regarding PS in the perioperative period of the evaluated hospital, considering the obstacles and challenges encountered during the nursing technician's activity that, in some way, threaten the quality of the service provided and PS in the surgical environment. As contributions, this research adds to existing knowledge about the nursing technician's activity in the surgical process, its importance and its relation to PS; demonstrates the applicability of the AET method for this type of research; establishes a theoretical, methodological and practical relationship between Ergonomics and PS; and proposes measures to reduce the occurrence of AEs in patients during surgical processes. For future work on this topic, it is suggested to replicate the methodology of this research in similar activities in other SC of public and/or private hospitals at national and international levels, and that comparative analyzes be carried out, aiming to reduce AEs during care surgery.

The objective of this study is to investigate which are the main factors that influence the use of loyalty programs in small and medium-sized companies in high-end retail in the state capital. Loyalty programs emerged in the eighties with the purpose of developing searches among consumers and companies, having a great importance in the business sphere, becoming an essential tool for customer retention. Technological evolution and the transformation of society contributed to the formation of new consumption habits, since consumers are always in search of new products and services, and it is also necessary, the evolution of companies to keep up with new needs, causing one of the greatest business challenges, to know more deeply the customer's consumption habits. All loyalty mechanisms occur in the approach of the customer to the company, the use of these mechanisms allows the obtaining of important information to improve the relationship with the customer, analyzes the level of satisfaction and understanding their needs, thus adjusting the services with the information obtained, ready for a competitive advantage in the face of great market competition, gaining loyalty and reducing the risk of losing it to competing companies. In view of the market dynamics, it is essential to understand the factors that influence consumer behavior, such as: social, personal and psychological factors, which contribute to the formation of the customer's profile. Social factors determine how decisions taken by the consumer in relation to a product or brand from the position it occupies in society. Personal factors are considered individual aspects of each consumer as well as the subject's life condition. Regarding psychological factors, it involves consumption and the need for satisfaction. The standard of consumer procedures has been changing at increasingly shorter intervals and knowing the stimuli that enhance these changes gives the company strategic advantages over other competitors. The research has a proposal that will be developed through a questionnaire, based on the understanding of the use and implementation of loyalty programs in business strategy, not small and medium-sized high-speed retail in the city of Natal, by the retail segment. Finally, the expected result is to better understand the essence of this tool and suggest a roadmap to guide its implementation.

The digitalization of processes in accounting offices is a slow but evolving reality in the northeastern region of Brazil. The fear that the digital age might render the accounting profession obsolete is gradually being replaced by confidence in the transformation of the accountant's role. A new profile of the accountant is emerging: the advisory accountant, a professional with technical expertise capable of assisting top management in strategic decisions by providing vital insights into a company's financial health. In this context, the rapid proliferation of numerous software options for a range of accounting services leaves professionals ill-prepared to make urgent and complex decisions. This situation jeopardizes the continuity of accounting businesses. This study proposes a multi-criteria model to assist accounting offices in selecting software for mandatory tax and accounting reporting. This aids in a secure transition to full digitalization of accounting offices, offering managers a tool to overcome the mentioned challenges and more. By employing the Value-Focused Thinking (VFT) methodology in conjunction with the FITradeoff decision support method, this study presents a methodological approach to the selection problem, guiding toward the best solution for each business profile.

Based on Data Envelopment Analysis and the portfolio management theory proposed by Harry Markowitz, this paper studies the efficiency of asset diversification to compose an optimal portfolio of stocks among the shares of companies listed on the Brazilian Stock Exchange (B3). It is founded that from economic data of the companies, allied to the macroeconomic and political conjuncture, the use of statistical resources and application of the Network Data Envelopment Analysis (NDEA), it is possible to construct a sample of papers whose diversified combination makes this investment portfolio optimal for the investor's profile. To carry out this assessment, a multiple case study was conducted, with an intentional sample of 180 companies registered at B3, with data referring to each quarter of the year 2022, disclosed by each company in the sample. The variables used in this evaluation were two inputs (operating expenses and total assets), two intermediate inputs (net income and total revenues) and two outputs (average return on shares in the market and volatility). Then, the output-oriented NDEA was used to identify which companies are efficient to compose a stock investment portfolio. To measure performance and analyze the portfolio, the Ibovespa index, the main performance indicator for shares traded on B3, was chosen as a benchmark. The test resulted in a positive response to the hypothesis formulated regarding the possibility of success of this diversification method. Finally, it concludes with the recommendation of the method, being an adequate strategy to assist investors in decision making. and that can be complemented by means of predictive resources, such as the bootstrap model.

In light of climate change, extreme events have become more frequent, exposing the vulnerability of critical infrastructures, including school buildings. This reality has exacerbated risks in already vulnerable educational facilities, highlighting the urgency to reevaluate and strengthen inspection and maintenance processes to ensure the safety and well-being of students and educational professionals, in line with scientific literature recommendations on risk management and climate adaptation. In this context, the research focused on analyzing the security inspection process of public school buildings in Natal-RN, identifying the main constraints that impacted the effectiveness of these inspections and assessing their relationship with the prevention and mitigation of disaster risks. The Ergonomic Work Analysis (EWA) was employed as the principal methodology, using techniques of direct observation, interviews with municipal engineers, and document analysis. The findings revealed significant gaps, such as the lack of standardized procedures and inadequate training of inspectors, resulting in variability in inspection practices that compromised the safety of the facilities. It was concluded that it is essential to reformulate the inspection processes to incorporate standardized procedures and specific training, aiming to enhance the efficiency of inspections and the safety of school buildings. It was also recommended to implement robust risk management practices, adapted to the new realities imposed by climate change, to ensure that school infrastructures effectively protect all their occupants.

Wind farms must regularly interrupt your energy production to perform the programmed maintenance. Since this pause causes losses in generation and any shortfall must be compensated with energy purchases on market, it is essential to determine the optimal time to apply the maintenance for wind turbines. Predicting wind speed through mathematical models has made it possible to define real-time production operation and equipment control. Therefore, this research has the objective in propose a model for planning wind turbine shutdowns for maintenance with use of wind forecasting and digital twin. This work was performed in three steps. The first step involved literature research about asset maintenance, wind forecasting and digital twin. The second step included the systematic literature review about the prediction models used the recent times with applications to maintenance and digital twin. The third step covered conceptual modeling for wind turbine maintenance planning and application on a wind farm. The proposed model corresponds to a combination of predictable multi-turbines spatiotemporal correlations framework method with an optimal maintenance schedule model. It consists of a probabilistic model, using predicted wind speed data and electricity spot market prices, also estimated in a stochastic program called Newave. Wind speed data is used on the multi-turbine spatiotemporal correlation algorithm; simultaneously two autoregressive moving average methods are applied for a long-term forecast of one week, while the other one is done in months. During the forecasting process, the input data is adjusted continuously for any variation. This correction is possible through the virtual simulation of the turbines using the digital twin, making the model a monitoring system with real-time feedback. The maintenance program for applying the model is centered on planned corrective, preventive and predictive methods, a decision-making is applied to choose the optimal time to interrupt production and carry out maintenance.

The slowdown in global warming depends on technological, economic, social, political, financial and environmental issues. The current energy source is mainly based on fossil fuels, which is one of the main causes of the increase in the planet's temperature. As an alternative to fossil sources, there are renewable energies such as wind, solar, among others. However, both wind and solar are considered intermittent sources of electrical energy generation. Due to this, hydrogen and green ammonia emerge as the main options to complement this intermittency and enable an energy supply system with greater participation from wind and solar sources. However, all economic activities generate environmental impacts and these must be analyzed so that the negatives are mitigated and compensated, as well as the positives enhanced in the process. The study aims to develop a model for assessing environmental impacts in the production, storage and transport of green hydrogen and green ammonia. In the first stage, exploratory theoretical research was carried out and followed by a Systematic Bibliographic Review (RBS). In the second stage, a case study was carried out on the environmental licensing process and the environmental impacts on oil and gas projects in Brazil. The third stage included validation through a Focus Group group and the final structuring of the environmental impact assessment model in the production, storage and transport of hydrogen and green ammonia. The proposed model will assist future investors in these activities both in Brazil and around the world, as well as environmental licensing bodies in making decisions regarding the environmental impacts of the hydrogen and green ammonia industry.

Globalization and the widespread use of the internet have transformed the relationship between consumers and companies, establishing direct and active interaction between them. In this scenario, understanding the customer lifecycle is vital to maintaining the operational and financial stability of organizations, with a sharp focus on factors that promote customer satisfaction and loyalty. Faced with the issue of churn – which reflects the loss of customers – several industries face challenges that directly impact their profitability and sustainability. Therefore, this research aims to develop a tool that improves predictive churn modeling, enriching it with causal analysis to not only predict more accurately, but offer clear interpretations of the reasons for customer loss. Using the IBM Telco Customer churn dataset, version 11.1.3, as empirical support, the study seeks to identify variables that influence churn and evaluate effective retention strategies. The methodological approach includes the use of machine learning techniques such as LGBM combined with advanced causal analysis methods such as Double Robust machine learning and Conditional Average Treatment Effects, CATE, modeling. Developing a tool that helps identify customer retention factors, from demographic aspects to the nature of the services provided, analyzing variables such as type of contract, gender, age, among others. The results are expected to validate the theories of Wu et al. (2021) on churn prediction and reveal profiles of customers with a greater propensity to abandon, as exposed by the authors of Rudd et al. (2021), contributing significantly to customer relationship management and offering strategic data for the development of more assertive retention tactics.

The decarbonization of the energy sector and the reduction of greenhouse gas emissions represent the main objectives of the energy transformation roadmaps. Considering that, renewable energies play a key role in world’s energy transition. However, the availability of these alternative energies varies over time and additional measures are needed to integrate fluctuating sources of renewable energy. The production of Green Hydrogen from the Offshore Wind source represents a complementary alternative for energy security supply, especially considering Brazilian’s wind energy capacity factors of up to 50.0%. Because it is an alternative and recent technology, research on its implementation is still lacking. Thus, this research aims to propose a techno-economic and environmental conceptual framework for green hydrogen production from offshore wind energy. The methodological procedure of the research consists of four phases: first, a theoretical foundation, Systematic Literature Review and case studies were conducted. Second, formulation of the conceptual model. Third, validation of the conceptual model. And the fourth, framework modeling. At SLR, 72 articles were analyzed, in addition to theses, dissertations and technical reports. As a result, 38 variables were identified and the conceptual model were systematized, grouped by similarity, considering the life cycle of a unit producing green hydrogen from offshore wind energy. The conceptual framework is divided into technical variables (wind farm, electrolyser and hydrogen), economic variables (costs, indicators, parameters and revenues) and environmental variables. In conclusion, the conceptual framework model for economic analysis of green hydrogen projects from offshore wind energy considers technical, economic, and environmental aspects as input data, as well as serving as a basis for more technical-economic and socioenvironmental feasibility studies for Green Hydrogen projects from different renewable sources.

Museums are institutions that were created to acquire, conserve, investigate, disseminate and exhibit the material testimonies of humanity and its surroundings, to promote education, citizenship, culture, enjoyment and quality of life in society. Even though they hold works of cultural and material value, have employees and receive a diverse visitor population, many museums lack, or partially have, accessibility and disaster prevention and response systems, in particular, an emergency evacuation system. This research project aims to analyze the accessibility and emergency evacuation conditions of museums in the city of Natal, Rio Grande do Norte, and the preparation of the user population (employees and visitors) for safe evacuation from the museum in an emergency context. The population studied in this research comprised employees and visitors to the museums in question. Initially, a bibliographical search was carried out on the topic of this research in the Periodicos Capes virtual library and documentary research on standards and legislation on accessibility, emergency and evacuation systems. Then, using the Global Analysis Guide for Museums, a survey and general characterization of existing museums in the city of Natal were carried out, in which a standard checklist was applied to evaluate the compliance of accessibility and systems or devices emergency and evacuation of each museum for the user population. Then, based on the Ergonomic Work Analysis (EWA), a case study was carried out in one of the museums in the city of Natal/RN, which was chosen for convenience. In the case study, the Case Study Museum's Global Analysis Guide was applied, to understand its structure, organization and global functioning, the Visitation Observation Plan, to identify accessibility problems, and the Conversation Guide with employees, museum managers and visitors to analyze their perception regarding accessibility, risks, emergency systems and evacuation. Also, a simulated exercise was carried out, with an emergency scenario inducing the evacuation of the museum's user population, to analyze their behavior in the face of the simulated emergency situation. To assess the perception of risk and the museum's accessibility, emergency and evacuation systems by the user population, a questionnaire was administered immediately before and after the simulated exercise. Also, immediately after the simulated exercise, the Conversation Script was applied to the user population that participated in the simulation to comment on the emergency scenario applied and the museum's accessibility, emergency and evacuation systems and their relationships with the behaviors assumed by them. in front of the simulated scenario. It was observed that museums that had their accessibility and emergency compliance assessed needed improvements in both the physical and informational accessibility system and the emergency system. It was also observed that the simulated exercise carried out in the case study museum contributed to sharpening the participants' risk perception and improving the museum's accessibility and emergency system. This research contributes to the theoretical and methodological knowledge of Ergonomics and Accident or Disaster Risk Management, considering the application in museums, and, from a practical point of view, to the efficiency of emergency evacuation of the case study museum and to the improvement of public policies, management and architectural and emergency projects for museums, with regard to the safety of the user population in emergency situations.

The complexity of rare diseases, exemplified by Amyotrophic Lateral Sclerosis (ALS), requires a specific approach from public policies and health services. The typical public health structure, designed for common diseases, may not be suitable for meeting the needs of patients with ALS due to its complex nature. The effective delivery of health services to these patients necessitates multidisciplinary care with collaboration, coordination, and transition among various health professionals and services. To promote quality care, it is crucial to structure health services through Care Pathways, which play a key role in the organizational care within health networks. This encompasses different care processes, health units, and levels of attention through care flows. Given the need to ensure comprehensive, coordinated care along the care pathway, it is necessary to map and organize care flows, from the patient's first contact with the health system to the conclusion of treatment or follow-up. Therefore, this research aims to propose a framework for standardizing care pathways for ALS patients in the public health network of the state of Rio Grande do Norte. The research procedure was divided into three phases: (i) theoretical foundation, conducting a Systematic Literature Review based on the PRISMA method; (ii) identification and characterization of care processes and flows for ALS patients, based on literature data, public health database of RN, and interviews with professionals directly involved in the care of ALS patients; and (iii) construction and validation of the care flow framework for public health network patients with ALS, based on the RarERN Path methodology and the Delphi Method. The expected results include the development of a framework with consolidated and validated care flows by a team of specialists. These flows should be patient-centered and focused on their care journey. Additionally, this structure is expected to standardize the patient's pathway through the health care network and improve the coordination among different professionals involved in care. Finally, the proposed framework could be used as a concrete subsidy in implementing a specific Care Pathway for ALS and serve as a model to address challenges related to other rare conditions.

Clinical Research is defined as any scientific investigation conducted on humans, involving experiments of high methodological rigor, aimed at discovering new treatments for diseases and assessing the safety and efficacy of new drugs. This provides answers to various questions related to therapeutic practices and the quality of healthcare services. Patient Safety is becoming an increasingly discussed topic in light of the new services offered by healthcare. ANVISA established in RDC No. 36 of 2013 the requirement for the creation of Patient Safety Units in healthcare services and the reporting of Adverse Events (AE) associated with patient care. In Clinical Research Centers, it is necessary that all clinical study protocols are conducted with the highest quality required by pharmaceutical companies and regulatory agencies, ensuring adherence to the protocols with guaranteed quality, reporting any AEs or errors in the study protocol processes, and continuously developing a culture of improvement. The methodology of the Association for the Accreditation of Human Research Protection Programs (AAHRPP) proposes a quality certification in Patient Safety in Clinical Research through quality procedures and policies. The main objective of the research is to analyze bibliographic studies in scientific databases directly related to institutions conducting clinical research, using AAHRPP methodology as a quality criterion for safety protocols. This study aims to bring the AAHRPP methodology to Brazilian Research Centers so they can use it as a basis for creating or monitoring their processes, making them capable of receiving proposals for globally relevant clinical studies. In doing so, it will bring science and new therapeutic technologies closer to the population, demonstrating how well-conducted clinical trials directly impact health promotion.

Clinical research invests large resources throughout its testing and approval phases. A very expensive step for pharmaceutical companies is the recruitment and selection of research individuals, which takes place through clinical trial centers. These, based on the protocols, are responsible for ensuring that recruitment and selection procedures, care, exams, monitoring and others, are carried out efficiently and effectively, both in the use of resources made available by the sponsor, and in the generation of data. real, quality and within the deadlines determined by this stakeholder. Among the activities carried out by research centers in clinical trials, recruitment is considered one of the most relevant parts, since without volunteers there is no study. Having quantity combined with quality is a crucial factor, as well as reaching the goal agreed with the sponsor in a timely manner, ensuring that the study does not become dispersed and take much longer than planned for its development, resulting in increasingly higher costs. In this context, adapting the center's operations to the requirements of the specific protocol is essential for the adequate progress of activities. The general objective is to propose a framework based on Lean Healthcare for the adequate preparation of research centers, aiming to guarantee recruitment and conduct of clinical trials with efficiency and quality. In this sense, the study deals with the results of a research center, which promoted the remodeling of clinical trials, based on a systematized sequence of steps to be followed before starting the protocol. To define these steps, the Lean Healthcare methodology was used as a basis, from its concept to its tools, in the search for added value from the patient's perspective, acting through the identification, development and analysis of their value streams, with aimed at quality, productivity and effectiveness in meeting the proposed goals. To validate the new established process, an action research was carried out, which resulted in the real scope of recruitment carried out in record time by the research center, in the participation of a study for a vaccine against COVID-19 together with other centers spread around the world. around the world, with this company being responsible for including (randomizing) 3100 volunteers during 18 days of recruitment, with an average service lead time of 3 hours in visit 1 of the trial. Finally, a process framework is proposed, containing the main steps identified as key to achieving the expected results.

Conventional port impact studies have focused on positioning port interactions as static entities that focus only on port impacts, ignoring implementation impacts, future effects of port development, changes in port operations, and uncertainties that influence the city system. port. Port and urban systems have been studied as dissociated entities, thus demonstrating the need for instruments for evaluating socioeconomic performance indicators considering the port-city relationship. Therefore, the objective of this research is to structure a framework to guide the evaluation of socioeconomic performance in the implementation phase of a port-industry, with a view to supporting decision-making in managing performance and impacts on the local community. This tool can be applied by port authorities and companies operating in the port or even for future port facility projects, as a tool for monitoring and adapting socioeconomic management. Information was collected from case studies and the dimensions were systematized. Indicators and aspects of some social, economic, governance, spatial, general and sector-specific performance instruments were also considered. As a result, the research brings innovation to performance assessment considering socioeconomic aspects with success drivers throughout the port's implementation phase.

In the early 1970s, several countries began to question the use of energy sources from fossil sources and non-renewable resources, since their depletion would be inevitable and, above all, because the emission of toxic gases and particulate matter that deposit in the atmosphere grew frantically, threatening the quality of life on Earth for future generations. In this sense, it was essential to change the energy matrix, which led to an expansion in the demand for clean energy sources. Among these matrices, the wind, that is, the generation of wind energy, which since the 1990s has been growing worldwide, including Brazil, a geographically privileged country in this sector, where, in 2021, there were 84 wind farms in the construction phase. projects and 21 under construction, and, consequently, a significant contingent of workers involved and accidents at construction sites. However, the scarcity of data on these occurrences was observed, although it is estimated that there is underreporting of such accidents. It is a fact that civil construction (despite already published Occupational Safety standards) has a high rate of accidents at its sites, which may be related to the organizational culture disseminated in these undertakings. This scenario motivated the formulation of the following research question: what is the influence of the organizational culture on compliance with the norms implemented by the Occupational Health and Safety programs in the construction of Brazilian wind farms? Therefore, the general objective of this study is to analyze the influence of organizational culture for compliance with the rules implemented by the Occupational Health and Safety programs in the construction of Brazilian wind farms. To this end, a case study was prepared, of a basic nature, having as its object two wind farm construction sites (one located in Bahia, the other in Rio Grande do Norte). According to the objectives of the study, the research outline is descriptive, and its logical argumentation followed the deductive method. Secondary data were collected through bibliographical research and primary data by the researcher himself, through systematic participant observation, supported by a field diary. The Bradley curve was used to fit the data on the number of accidents and the maturity of the organizational safety culture in the two wind farms studied. The analysis of the results followed the qualitative approach.

The importance of correctly choosing strategies for reducing ergonomic risks in blood centers is crucial for the health and well-being of professionals. The activity of plasmapheresis presents significant ergonomic risks, demanding effective mitigation strategies. Given the relevance of this prioritization, it is essential to adopt a structured and well-founded approach in choosing strategies for risk reduction. This study proposes the development of a model to assist in the prioritization of strategies for reducing ergonomic risks in plasmapheresis activities at blood centers, using the "Value-Focused Thinking" (VFT) methodology in conjunction with the FITradeoff decision support method. The research was conducted by applying the model in a large blood center located in Fortaleza, Ceara. The developed model considered 7 criteria and 5 alternatives, representing ergonomic strategies, and was applied in collaboration with the plasmapheresis coordinator of the blood center Thus, the model provided a prioritization for better application that meets the organization's profile, demonstrating high robustness according to sensitivity analysis, in addition to being validated by the decision-maker and the board.

The incessant search for effective therapeutic strategies for children diagnosed with Autism Spectrum Disorder (ASD) is a clinical and social imperative, considering the significant prevalence of this disorder in childhood. Psychomotricity is understood as the interaction between motor, cognitive and affective processes, emerging as a valuable tool for understanding and intervening in the psychomotor peculiarities present in ASD. In this context, the intersection between psychomotricity and Autism Spectrum Disorder (ASD) has been the subject of growing interest in scientific literature, considering the complexity of this disorder and the need for holistic approaches to promote the integral development of diagnosed children. Given this scenario, several gaps in the diagnosis and evaluation that structure the Singular Therapeutic Project (PTS) are found in the literature, with the main problem being the lack of tools that optimize and guarantee the quality of this therapeutic intervention. Therefore, this study proposes an innovative and pioneering analysis, focusing on the application of quality tools, the integration of risk analysis and the use of graphs to improve the elaboration of the Singular Therapeutic Project (PTS) and solve its existing gaps, aiming to integrate different scientific disciplines, offering a data-driven and personalized approach to optimize PTS for children with ASD. Its main objective is to investigate and develop optimized psychomotor intervention strategies within the scope of the Singular Therapeutic Project (PTS) for children with Autism Spectrum Disorder (ASD), through the integration of quality tools, risk analysis and graphs, aiming to enhance the motor and cognitive development of these children. With the development of activities related to research in health services, it is expected that the qualification of professionals and clinical intervention will be shaped seeking a higher level of quality in care and at the end of this study it is expected that professionals and managers will accept the model proposed in health rehabilitation centers.

Lean leadership is fundamental to the effective implementation of continuous improvement and innovation practices in organizations. This approach emplasizes the importance of leaders who not Only manage processes, but who also inspire and empower their teams to seek constant improvement and innovation. The Lean methodology, including Kaizen, offers tools that facititate this cultural and operational transformation. The objective of this study is to investigate the influence of leadership in promoting innovation and implementing improvements within organizations. Based on a literature review, the work seeks to deepen the analysis of the relationship between leadership and innovation, highlighting the scarcity of research that examines this interconnection in more detail. The relevance of the topic is evident both for society, from the perspective of workers, and for the survival and competitiveness of organizations. The study emphasizes the importance of understanding the role of leadership in production systems, with special attention to innovation, creativity and continuous process improvements, such as those promoted by the Kaizen methodology. These elements are essential to increase the chances of success and sustainability of organizations. A clear example of this relationship is the Lean Production System, whose global success is often attributed to the Japanese culture, which was responsible for its creation and dissemination. However, this research proposes that the effectiveness of the Lean system fundamentally depends on the type of leadership implemented. Through a critical analysis of the literature on the Lean Production System, transformational leadership and organizational change processes, this study aims to demonstrate the central role of leadership in the implementation and success of Lean practices. To explore this dynamic, a framework was developed that analyzes the interconnection between different leadership styles and the application of Lean principles. This framework assesses the impact of different leadership approaches on the adoption and effectiveness of Lean tools in organizations. The results obtained offer valuable insights into the role of leadership in facilitating organizational change and promoting continuous improvement. The study highlights, in particular, the need for strategic and adaptive leadership, which is essential to ensure the sustainable success of the Lean Production System. By integrating innovation, creativity and continuous improvement into organizational processes, leadership becomes a determining factor for the competitive performance and longevity of organizations.

Given the growing demand for specialized mental health services and the global reduction in psychiatric beds, it is essential to implement effective interventions to regulate these beds. Efficient management of this demand requires careful classification, in which the regulatory professional considers multiple criteria for decision-making. In this context, Multi-Criteria Decision Analysis (MCDA) stands out as a robust support tool. This study aimed to develop an MCDA model to classify and prioritize patients at the Rio Grande do Norte Regulation Center. The research, applied to the Health Regulation and Assessment Coordination (CORSA), was conducted in three stages: planning, structuring and analysis. In the structuring phase, the Value Focused Thinking (VFT) method was used to identify relevant criteria and a twelve-step framework for modeling. As a result, five main criteria for bed regulation were identified: heteroaggressiveness, degree of assistance, clinical stability, suicidal ideation or attempt and belonging to special populations. The FITradeoff method was chosen because it reduces the decision maker's cognitive effort. The model was validated by classifying patients according to the reality of the regulatory center, demonstrating high robustness (more than 90%) in the sensitivity analysis. It was concluded that the application of the model optimizes bed regulation, proving its potential to support decisions based on multi-criteria criteria

University management is characterized by a particular complexity, given the multiple objectives that need to be integrated. In the context of postgraduate education, the strategic management of program indicators is a challenge that requires planning and continuous monitoring of defined goals and actions. The objective of this study is to develop a strategic management model for postgraduate programs based on CAPES's quadennial assessment. Therefore, four methodological steps will be applied to the program under evaluation, namely: documentary analysis of CAPES evaluation of the program area; application of management tools for diagnosis; construction of strategic planning; and continuous monitoring of its indicators. As a result, a better understanding is expected regarding the criteria that have greater weight for evaluating the program, as well as identification of the program's current scenario in terms of its main deficits and which goals need to be achieved to improve its concept; and, mainly, the guideline for implementing a strategic management routine for the program, with continuous monitoring of its indicators.

The demand for renewable energy is growing, and offshore wind energy is one of the options with high potential to be used by society. An offshore wind farm, due to its location in the maritime environment, faces restrictions that tends to increase the complexity of its operation and maintenance. To address these challenges, it is important to use tools that assist in operation and maintenance activities and decisions, such as the digital twin technology integrates physical and digital means for real-time monitoring of an asset or a production process and makes it possible to anticipate possible failures or unwanted events. The objective of the research is to develop a framework with guidelines for implementing digital twin in the operation and maintenance of offshore wind turbines. The research is characterized as descriptive, applied, and with a qualitative approach of inductive argumentation. The research was developed in four stages: (1) theoretical research, where exploratory research and a Systematic Literature Review were carried out, with analysis of 54 articles, (2) analysis of eight case studies on the use of digital twin (3) development of the conceptual model; and (4) validation of the conceptual model based on expert opinion - focus group. As a result, a framework with four dimensions is proposed: digital twin characteristics, implementation steps, digital twin components, and parameters for analysis. These dimensions provides guidelines for implementing the digital twin in offshore wind turbines by describing tools, applications and systems that can be used for this purpose. For future research, further exploration of the tools described is suggested, as well as to apply the digital twin to other assets of an offshore wind farm.

**Translation:**
Knowledge management, or KM, is a highly sought-after topic in various fields of science, sectors of activity, professions, and organizations in both the public and private sectors. Over time, this topic has been implemented as a strategy from various perspectives, serving as a management method to disseminate business information. Whether internally, through employee training at various levels, or externally, as part of marketing and sales campaigns. Thus, strategically managing knowledge within an organization promotes improvements in its internal systems, increases productivity, business viability, and enhances its image and brand in the market. The organizational strategy aims to create an organizational culture involving all the company's stakeholders.
The objective of this project is to develop a framework for the fiscal and human resources areas in public administration. To carry out this research, the first step was to systematize the state of the art on the topic in order to organize the concepts, techniques, and tools used in Knowledge Management (KM). In a second stage, the main areas of knowledge concentration in the software development process were identified, classifying them according to types and importance, based on the knowledge produced. Furthermore, the literature was consulted to find references for managing this knowledge.
Finally, a model was abstracted to structure the processes for implementing KM in the processes of development and maintenance of public management software. Based on this research, companies that develop software will be able to use it as a practical application standard for KM in their processes. They will be able to identify the different evolutionary stages of KM they are in and, as a result, improve their market positioning. The results lead to better identification of a conceptual model to assist in management and decision-making for the manager of a software development company.

The school dropout is a complex and multifaceted phenomenon that represents one of the most significant challenges faced by educational systems and a topic widely discussed by researchers worldwide. Efficiency, in turn, is a crucial measure of an educational system's ability to achieve its objectives effectively, optimizing resources and maximizing the impact of investment in education. However, the relationship between school dropout and efficiency is not just causal since dropout directly compromises the efficiency of the educational system. The objective of the research is to propose a relational model of factors that allows us to examine the interconnection between dropout rates and academic efficiency, based on a case study of a unit of the Federal Institute of Paraíba, located in the city of Itaporanga/PB. The research will be developed in the integrated high school at Campus Itaporanga, initially being conducted through a survey with the purpose of collecting data necessary to build the relational model. Likewise, select variables to calculate academic efficiency using the Data Envelopment Analysis (DEA) technique, to compare the result with other IFPB units. Initially, the State of the Art on the topic was surveyed, covering the following focuses: Social and institutional aspects, Racism, Psychosocial factors, and LGBTQ+ inequality. These variables were the result of the synthesis of 97 articles found in the Scopus database, using the keywords Truancy and Absenteeism. The study will be conducted in six sequential stages: 1) exploratory literature review; 2) systematic bibliographic review (RBS); 3) description of variables; 4) efficiency calculation using the DEA technique; 5) carrying out the case study and survey; and 6) elaboration of the relational model. As expected, results of the research, build and validate the relational model framework, calculate the academic efficiencies of the course, and compare with other units in the same segment, to verify the variables with the greatest impact. Compare the results obtained with the results found by authors in the area to contribute to the literature around school dropout/efficiency. There are many opportunities for future research and methodological developments.

Gender inequality is expressed by sexism, machismo, and misogyny perpetrated by a patriarchal culture imposed by men on women since the beginning of humanity. In various sectors and cultures of society, women still suffer from a lack of opportunities and space. Thus, education has a transformative role because only through education is it possible to eliminate social gender barriers and transmit knowledge in an egalitarian manner, with awareness and respect. In this context, this work aims to evaluate an educational project that throughout 2023 trained 75 female students from 20 public schools in Rio Grande do Norte, in addition to 15 undergraduate and graduate students who acted as tutors, through actions based on active methodologies focused mainly on the aerospace sector, aiming to disseminate the concepts of astronautics and introduce this topic to teachers and students. Projects like this are extremely important in building a more egalitarian society because they encourage and provide an increase in female participation in the economically active population.

The Brazilian Space Agency (AEB) has the mission to coordinate and strengthen the national space sector for societal development. Among AEB's strategies to promote space education are events, educational projects, courses, and workshops. However, challenges arise from local limitations, staffing issues, discontinuity in financial investments, a lack of motivated teachers in STEAM education, insufficient university infrastructure, and students lacking basic knowledge, which create barriers to the success of these initiatives. Conversely, some universities possess adequate space and laboratories, research funding, event sponsorships, and civil society support that enhance educational projects aimed at inspiring youth to pursue careers in space. In this context, universities play a crucial role the social actors involved in the educational process and the effective functioning of the triple helix model for technology transfer. They serve as the central agent of knowledge infrastructure essential for a robust space industry, directly linked to the education and training of qualified professionals. The goal of this dissertation is to identify the facilitating and limiting factors for the success of research projects in the space field, validate these variables through questionnaires with active teachers, monitors, and coordinators, and analyze the impact of each variable on Brazilian projects. This study will employ data triangulation—a method combining different data collection techniques conducted in four stages. Data research in the Scopus database yielded 69 articles after applying filters and content analysis. Due to the low number of recent articles (from 2019 to 2023), conference papers were also included, resulting in a database comprising 73 articles from events such as the Brazilian Aerospace Congress (CAB), American Society for Engineering Education (ASEE), Brazilian Engineering Education Congress (COBENGE), and International Astronautical Congress (IAC). After further analysis, the total number of articles reached 89. The identified variables were organized into clusters: five groups of barriers—Government Actions; Structure; Financial Incentives; Team; and Deliverables—and six groups of facilitators—Government Actions; Structure; Financial Incentives; Team; Social Impact; and Basic Education. For validation, a questionnaire will be applied to teachers, monitors, and project coordinators from UFRN's GLOBE group and other identified projects registered with CNPq.Expected outcomes include validating factors identified in global literature but confirmed by practitioners in Brazil's space sector. This could generate relevant data for developing various methodological approaches with potential insights for public policy makers and decision-makers. Another consideration is the possibility of mapping facilitators and barriers according to their respective project phases (Planning, Execution, Post-Project). This will enable identification of which factors influence each variable at its project phase, promoting more effective interaction among universities, research institutions, and the private sector while contributing to the country's socioeconomic development.

This research aims to highlight the potential environmental and construction benefits of using sustainable bricks in civil construction, proposing a construction alternative that combines sustainability, efficiency and technical feasibility. Using a combination of water, cement, soil and Construction Waste (CDW), the ecological brick presents itself as a solution to reduce the environmental impact of the sector, while contributing to the construction of cleaner buildings. Unlike conventional bricks, the proposed product eliminates the use of biomass in the firing stage, as its curing occurs naturally, outdoors, under careful humidity control. This process results in a significant reduction in CO₂ emissions, meeting sustainability criteria and making it a more responsible and innovative option. The research was conducted in the laboratories of the Federal University of Rio Grande do Norte (UFRN), where a series of experimental tests evaluated the technical feasibility of the material, exploring its physical-mechanical properties. The methodology adopted included an initial bibliographic review, essential to theoretically support the study, followed by the preparation of inputs and production of sustainable bricks. After natural curing, the bricks were subjected to laboratory tests to examine their compressive strength attributes in all tested proportions. These data were compared to references of conventional bricks and other sustainable materials, providing a productive alternative for ecological products. In addition to presenting advantages in the context of sustainability and construction efficiency, this work proposes an alternative for the construction sector, encouraging the use of waste as raw material, promoting the circular economy and reducing the pressure on finite natural resources. In addition, the developed bricks contribute to less polluting buildings, stimulating the development of construction practices that prioritize environmental balance. As a result, this research provides a basis for future innovations in the field of sustainable materials, inspiring the improvement of technologies that value efficiency, the preservation of natural resources and the quality of life in cities.

The effective management of the classroom in higher education has become a priority due to the growing need to create more dynamic, personalized, and efficient learning environments. The transition from traditional teaching models to more innovative approaches requires careful strategic planning, combined with the use of tools for continuous monitoring and feedback. In this context, students are treated as "clients" of the learning process, and classroom management must be structured to address their needs in a more assertive manner, promoting focused, dynamic, and collaborative learning. The use of monitoring platforms and performance indicators has the potential to optimize management, allowing for rapid adjustments in teaching methodologies and providing a more personalized learning experience.
However, the educational process faces significant barriers that vary from the perspectives of students, teachers, and institutions. Students face challenges such as difficulty concentrating and the impact of excessive mobile device use, which directly affects their engagement with academic content. For teachers, the overload of work and lack of time for planning hinder the implementation of more student-centered methodologies. Institutions face structural and financial barriers that compromise the quality of teaching and the necessary technological support.
This work proposes the development of an integrated framework to optimize classroom management in higher education, overcoming the identified barriers and improving the management of the educational process. The proposed model uses tools such as progress dashboards and SWOT analysis to promote effective strategic planning, aligned with the needs of students and the objectives of the courses. The application of this framework will allow for continuous monitoring of student performance, adjustments in pedagogical methodologies, and a more collaborative approach focused on the development of students' competencies, adapting to the demands of contemporary higher education

The global demand for energy from renewable sources, driven by numerous societal benefits, presents a significant opportunity for Brazil given its high generation potential. As a producer of renewable energy, such as Onshore Wind Power, Brazil has embraced the idea of implementing Offshore Wind Power. However, operating in aquatic environments introduces unique operational challenges. Occupational safety in Brazil strives to ensure that activities are carried out with risk elimination or minimization. Given that offshore wind farms represent a new sector for the country, it is imperative to study occupational risks associated with the installation of these assets. This study aims to propose guidelines for standardizing occupational safety measures in the process of installing Offshore Wind Farms in Brazil. The research was developed in three stages: i) theoretical research on occupational safety, offshore environment regulations, onshore environment regulations, and regulations in the Oil & Gas sector; ii) case studies on occupational safety guidelines in the offshore wind sector in the United Kingdom and Denmark; and iii) structuring a proposal for occupational safety guidelines to support the development of activities in the installation of offshore wind farms in Brazil. The results highlight the importance of standardizing activities in this new segment in Brazil, ensuring that they are governed by specific regulations due to the critical need for maintaining safe environments and activities in light of the high risks associated with this sector.

Discussions on offshore wind energy in Brazil have grown significantly in last years. Its relevance stands out due to its contributions as a source of clean energy, attracting investments, and protecting the planet by using a renewable natural resource that reduces dependence on fossil fuels and reduces greenhouse gas emissions. The objective of the study is to propose technological, infrastructure and strategy alternatives for the collection and transmission of electricity from offshore wind farms applied in the Brazilian reality, focusing on optimizing the overall cost. The study is characterized as an applied dissertation, with a qualitative approach, with an exploratory objective and employs bibliographic procedures and a focus group. The research procedure includes three stages: I) The first stage consisted of theoretical research that used theoretical exploratory research and a Systematic Bibliographic Review (SBR) to identify the current position of the topic on the collection and transmission of offshore wind energy, and its characteristics regarding the infrastructure and technologies used; II) The second stage consisted of the evaluation of the regulatory, guideline and technological aspects of offshore wind production through the analysis of technical reports; and III) The third stage included the structuring of technological alternatives, infrastructure and strategies for collecting and transmitting electricity from offshore wind farms and a validation analysis through a Focus Group. As a partial result, the distance between wind farms and the National Interconnected System is a crucial factor. In addition, technologies such as the Voltage Source Converter with High Voltage Direct Current (VSC-HVDC), associated with hydrogen production, were identified as promising solutions, despite requiring high investments in infrastructure and coordination of public policies. Weaknesses in the port infrastructure and in the specialization of the national workforce were also highlighted, in addition to the need for a favorable regulatory environment to enable the sustainable development of the sector. Finally, the study points out that public policies focused on research, development and public-private partnerships, as well as learning from international practices, will be essential to overcome technical and economic challenges and ensure that offshore wind energy becomes a promising reality in Brazil.
