The construction of vertical buildings presents unique challenges to ensure worker safety. Building Information Modeling (BIM) has emerged as a transformative technology in the architecture, engineering and construction industry, with multifaceted applications that extend beyond the design and construction phases. BIM changes the way safety can be approached as it offers new approaches for professionals to design or minimize hazards and risks through design analysis, simulation and other extensions. Designers do not understand the impact of their work on construction methods and safety, so it is necessary to bring this awareness of the responsibility their decisions can have on workplace safety to workers. The main objective of this work is to demonstrate, through a safe project model, how the prevention and reduction of accidents in the design phase works and to investigate the knowledge and interest of this type of project of civil construction companies in João Pessoa/PB. A Systematic Literature Review (SLR) was performed following the guidelines of the Preferred Report Items for Systematic Reviews and Meta-analysis (PRISMA) methodology, the studies found were divided into 8 groups. The main sources of accidents at the construction site were found, the main ideas of the authors, the life cycles of construction that can be inserted, effectiveness in training workers, benefits and limitations of using BIM for occupational safety. A case study was also carried out in two companies with the participation of 3 architects and 3 civil engineers. In this study, it was possible to verify the interest in using the presented safe project model. The benefits found in the literature were positively recognized by both companies. The biggest limiting factor found was the lack of customer demand. As for the degree of importance, it was analyzed that to develop this type of project, the use of BIM would be essential and that the execution would be the most impacted. This study is expected to contribute to the advancement of knowledge about BIM, to demonstrate the importance of multidisciplinary collaboration between teams, so that designers can consider worker safety in their projects, minimizing or eliminating the risks of accidents that exist during the entire construction cycle of the building.

This research analyzes how dynamic capabilities can assist firms in reducing barriers that hinder the implementation of more circular practices. Specifically, it aims to (i) present an overview of research on barriers and dynamic capabilities in the context of CE; (ii) identify the barriers that companies face during the transition to more circular practices; (iii) identify the dynamic capabilities that companies need to make the transition from linear to circular practices; (iv) propose a conceptual framework that integrates dynamic capabilities that can help reduce barriers that hinder the implementation of more circular practices in the context of Paraiba companies; (v) refine the conceptual framework through case studies and present research propositions. The method employed for the development of the empirical study was the case study in companies operating in the State of Paraíba. The main data collection instrument was the interview that was elaborated considering the proposed conceptual framework. From the literature analysis, which was carried out through the systematic literature review method to know the theme, as well as to identify dynamic capabilities and transition barriers to CE, it was found that it is an emerging theme. Among the dynamic capabilities that were identified in the literature, 27 capabilities were identified, which after a process of grouping, categorization and abstraction, resulted in 11 categories of capabilities. Also, 65 barriers were identified, which after the same process, resulted in 12 categories. The literature review also allowed the identification of several CE practices, the most recurrent being recycling, reuse, remanufacturing, recover, eco-innovation and others. Based on this information, it was possible to develop a conceptual framework that was applied in practice with 4 companies in Paraiba (called A, B, C and D) that have circular initiatives and practices. It was found that, among the 4 companies analyzed, the one that faced the highest number of barriers was Company D. And, the Company that best managed to use dynamic capabilities and implement CE practices were Companies B and D. In a comparative analysis (cross-case), it was found that the barriers that most hindered the implementation of circular practices in the companies studied were the lack of consumer awareness, lack of knowledge and lack of R&D (called B1, B2 and B3 respectively). The dynamic capabilities that stood out the most to help overcome the barriers and implement CE practices were the following: design and innovation capabilities and absorptive capacity. From the empirical results, it was possible to refine the conceptual framework and generate 12 propositions. Finally, it is worth highlighting the contributions of this dissertation. The first contribution is derived from the integrative theoretical framework that shows difficulties/barriers that companies face when aiming to implement CE, and how they can overcome such barriers from dynamic capabilities. This framework can be used by other researchers who intend to explore the topic. A second relevant contribution is the 12 propositions generated from the empirical studies, as they can be tested in future studies through hypothesis testing. Each proposition represents a carefully crafted synthesis of the observed connections between specific variables, reflecting a deeper understanding of the underlying dynamics. These propositions act as conceptual building blocks, providing a structured framework for assessing and exploring the relationships between barriers and dynamic capabilities in diverse business contexts. Third, it can be stated that the application of the framework in practice through case studies brought relevant information to the companies studied, as the realization of the research allowed some reflections on the difficulties, they have to implement a cyclical business model, as well as how such companies can overcome these difficulties through dynamic capabilities. Thus, companies had a greater understanding of how dynamic capabilities of absorption, design and innovation and organizational capabilities are helping organizations to overcome such barriers.

A hybrid heuristic for the blocking flow shop scheduling problem with makespan minimization

Hora: 13:00
-
Mostrar Resumen
-
Maximizing operational efficiency has become a priority for modern companies, driving the need to optimize the production flow, which plays a fundamental role in an organizations ability to meet market demands in an agile and profitable manner. In this regard, enhancing the job sequencing process is essential to increase productivity and reduce waste in a highly competitive market. Within this scope, this work addresses the blocking flow shop scheduling problem with makespan minimization. In this problem, n jobs must be scheduled in an environment of m machines ordered in series, in which all jobs must follow the same processing order. Furthermore, unlike the permutational flow shop problem, the intermediate buffers between these machines are considered zero. Thus, a machine can only release a job to the subsequent machine if this one is not occupied. A hybrid population heuristic that combines a ruin-and-recreate operator with a local search based on Variable Neighborhood Descent which makes use of acceleration methods is proposed to solve the problem. In this sense, a literature method for the insertion neighborhood was adapted for the block insertion and swap neighborhoods. Furthermore, lower bounds for the swap neighborhoods are also proposed with the purpose of avoiding the evaluation of moves that would not lead to an improvement of the current solution. Finally, a tie-breaking criterion and a population diversity control mechanism are employed to prevent the method from getting stuck in local optima. Extensive computational experiments were carried out on 150 benchmark instances, encompassing parameter calibration, evaluation of the tie-breaking criterion, performance of the neighborhood used, and other components of the method, such as the ruin-and-recreate operator and the diversity of the population. In short, the proposed method was able to obtain competitive solutions, with 94.67% being the best or equal to those found in the literature.

Additionally, there is no intermediate buffer between these machines. A hybrid population-based heuristic is proposed, combining a ruin-and-recreate operator with a local search based on Variable Neighborhood Descent, which incorporates search acceleration methods and a population diversity control mechanism.

Mostrar Resumen
-
The Robust Parameter Design (RPD) is a strategy based on mathematical and statistical models that aims to assist in the optimal selection of input parameters for a process, so that the influence of noise variables is minimized. When conducting robust optimization of a process, the objective is to maintain the desired mean and reduce variability, which is one of the main factors affecting product quality. Quality problems in the industry are often multi-objective, meaning there are multiple characteristics of interest for optimization, whether related to the product or the process itself. Capability indices are indicators capable of measuring and diagnosing the quality of a process. The
goal of this dissertation is to propose methods for process optimization through the implementation of a Robust Parameter Design, considering the existence of multiple response variables, and with the objective of maximizing capability indices. The use of these indices allows for simultaneous optimization of both the centralization and dispersion of the process. The proposed methods were tested and validated in an experiment of carbon steel ABNT 1045 end milling process. In these experiments, the optimal combination of parameters was feed rate (fz), cutting depth and width (ap and ae), and cutting speed (Vc). Among the noise variables, tool wear and cutting fluid concentration were included. As response variables, surface roughness (Ra) and specific cutting energy (Ec) were studied. To combine mean and variability and analyze process quality, Cpk indices and sigma level were utilized.

Hora: 19:00

Mostrar Resumen
-
Recent technological innovations are changing the way we produce and consume. Relationships with
customers are closer as connectivity and access to information have increased the level of demand for personalized products and services. These radical changes permeated all sectors of society and were associated with the German concept of Industry 4.0 (I4.0) linked to a conceptual relationship with the 4th Industrial Revolution. With the banking sector it was no different from the digitalization of service, active offer and consumption profile analysis are examples of practices of the so-called Banking 4.0 (B4.0). In this scenario, this research's main objective is to develop a maturity model for the implementation of Banking 4.0. From a systematic literature review (RSL), 16 technologies were identified, including e-commerce, fintechs and open-banking, for example, and practices that were linked to the use of these technologies and little associated with I4.0. Furthermore, from an RSL, we provide that Maturity Assessment Models (MM) are validated tools in the context of measuring the degree of implementation of I4.0 in the manufacturing sector, and can be adapted to any context. Generally, MMs consist of a sequence of maturity levels that represent a path of evolution, with the objects of analysis being evaluated in several conceptual dimensions according to their application context. Through this RSL, we list the main dimensions and levels found in the literature for manufacturing and which, in an adaptive way, supported the formulation of the MM for B4.0. Thus, after understanding the particularities of B4.0 and the dimensions and levels of an MM, it was possible to prepare an initial proposal for an MM for B4.0, with 5 dimensions, 4 levels and 42 maturity items. This model was evaluated by experts on the subject, resulting in a refinement of the model. With this improved tool, a case study was carried out in a Brazilian Bank in order to validate the proposed model. Respondents were able to assess the degree of importance of maturity items and the Bank's performance, generating data to obtain the Institution's Global Maturity. In the end, it was possible to affirm that the model is suitable for application in Banks as the interviewees positively evaluated the proposal, managing to identify the institution's performance within the maturity items and suggesting improvements to the model. The research contributes to the theory by having a pioneering nature in the formulation of a MM for B4.0, with a model evaluated by experts, as well as contributing to financial institutions in the holistic evaluation of the implementation of B4.0 in favor of better performance of result.

Universities, as spaces for the construction of knowledge and opportunities for individual growth, must strive to ensure an accessible environment for all, including staff with disabilities. The academic literature on accessibility in universities tends to focus on issues related to students with disabilities or, where it deals with staff, delves into the study of problems. In this context, based on a Systematic Literature Review (SLR) and a case study based on the methodology of Ergonomic Work Analysis, the aim is to identify barriers and facilitators that may hinder or contribute to the accessibility of employees with disabilities in a public university in Brazil. The case study used interactional, observational methods and documentary analysis, involving workers with physical, visual and hearing disabilities, managers and coworkers of people with disabilities, and members of the support team such as architects, psychologists, social workers and human resource managers. An analysis of the literature identified 83 barriers and 60 facilitators, which were grouped, categorised and abstracted into 6 dimensions: - Architectural (26 barriers and 13 enablers); - Communicative (07 and 07); - Methodological (19 and 15); - Instrumental (8 and 6); - Attitudinal (13 and 09) and; - Programmatic (10 and 10). On the basis of this information, it was possible to draw up an integrative conceptual framework relating the contribution of each facilitator to minimising or eliminating accessibility barriers. The use of a single facilitator, for example, suggests the elimination or reduction of the presence of several barriers, promoting accessibility under different possibilities. The case study identified some accessibility barriers and facilitators that are present in the daily work of disabled employees and were not mentioned in the RSL. It also provided a broad and indepth view of the findings from the perspective of different participants in the academic community. The research contributes to the field of knowledge beyond the employee audience by providing a list of barriers and facilitators of accessibility in universities as a whole, and a correlation between facilitators and barriers. The results of this research also make it possible to raise awareness and sensitise designers, professionals and administrators to a change in attitudes that will lead to a more accessible and welcoming university environment for all.

A prioritization model for the maintenance of medical devices
-
Fecha: 28-ago-2023

Hora: 19:30
-
Mostrar Resumen
-
Different non-manufacturing sectors have invested in structured procedures to improve mainte-
nance management. In healthcare facilities, this improvement in maintenance management is
additionally motivated by considerations of life risk to the patients, an element that increases
the complexity of maintenance and encourages the adoption of prioritization models. Bearing
this in mind, this research aimed to develop a model for prioritizing the maintenance of medical
devices that would be adequate to the complexity of institutions in the hospital sector. To this
end, a literature survey on the prioritization of maintenance of medical devices was first carried
out to identify criteria and evaluation tools used and propose a model based on best practices.
The proposed model initially uses the qualitative focus group methodology to select and classify
the most appropriate prioritization criteria for the studied organization in order of importance.
Furthermore, considering the established requirements, the model proposes applying the PRO-
METHEE-ROC method to establish the maintenance priority order within a group of devices.
In order to test its applicability, the model was parameterized for a large hospital chain and
applied to devices belonging to the surgical center and the sterilized materials center of a unit.
The results were considered adequate given the clinical engineering experiences and compared
to the existing maintenance schedule. They also indicated that the hospital unit could improve
prioritizing scheduled maintenance, specifically regarding understanding the importance of
sterilization equipment to the detriment of monitoring equipment, for example. In addition, a
sensitivity analysis was performed for changes in criteria weights, and a statistical correlation
test was performed to observe the accuracy of the analysis. The simulation was coherent and
consistent, with a significance level of 0.05%. Thus, the proposed model was considered ade-
quate to prioritize the maintenance of medical devices in the studied hospital chain. In addition,
the methodology adopted for constructing the prioritization model presented feasibility of rep-
lication and adaptation to the particularities of other institutions, which emphasizes the scien-
tific contribution of the research.

Thus, the proposed model was considered adequate to prioritize the maintenance of medical devices in the studied hospital chain. In addition, the methodology adopted for constructing the prioritization model presented the feasibility of replication and adaptation to the particularities of other institutions, which emphasizes the scientific contribution of the research.

Corporate and institutional debates on sustainable development within organizations have taken center stage in large companies, driven by stakeholder demands for ESG (Environmental, Social, and Governance) standards. In response, sustainability-oriented innovations (SOIs) have emerged as crucial adaptations, aimed at creating both social and environmental value while ensuring financial returns. The microfoundations (sensing, seizing, and reconfiguration) of dynamic capabilities (CD) serve as guiding principles in the strategic market, facilitating the transformation and propagation of resources and competences to foster these innovations.
Despite extensive literature focusing on various types of innovations, such as environmental, social, and sustainable, there remains a gap in integrating studies that examine SOI activities (Operational Optimization, Organizational Transformation, and Systems Construction) from the perspective of dynamic capability microfoundations. Additionally, there is limited understanding of how these microfoundations of dynamic capabilities influence the development of such activities within business projects. To address these gaps, this study employs the theoretical lens of DC microfoundations along with sustainability-oriented innovation activities. The primary objective is to analyze how DC microfoundations contribute to the advancement of sustainability-oriented innovation activities. To achieve this, a comprehensive literature analysis was conducted, identifying 19 microfoundations and 19 SOI activities. This information played a pivotal role in constructing the conceptual framework, which was subsequently validated through case studies involving four projects within an organization operating in the energy industry. Data for the case studies were collected through semi-structured interviews and project report analyses. These data were transcribed and then subjected to content analysis. The findings reveal a strong influence of the microfoundations of detection, apprehension, and reconfiguration on SOI activities, particularly in the context of Operational Optimization (OO) and Organizational Transformation (TO). Based on this empirical evidence, 19 research propositions were formulated, illustrating both strong and weak relationships between microfoundations and SOI activities. This study's contributions encompass the development and refinement of the framework, empirical research propositions, and the advancement of literature in the field. Moreover, it successfully integrates microfoundations themes of dynamic capabilities with perspectives on SOI activities.

Current studies related to sustainability show a growing trend. In the corporate environment, discussions on the incorporation of project management and sustainability ideas have been gaining new directions, especially in themes involving risks and sustainability in large projects. In this sense, this study seeks to confront the considered risks of sustainability, with an original analysis of the perceptions of stakeholders in a real project. For this, we present as a general objective to analyze the perceptions of sustainability risks in projects from the perspective of the stakeholders. And five specific objectives, i) to raise the main characteristics of the literature on sustainability risks in projects, considering the stakeholders involved, ii) to identify categories of sustainability risks in projects, iii) to investigate the perception of probability, impact, urgency and tendency of these together with stakeholders of a large project, iv) classify individual perceptions and influences of stakeholders against categories of sustainability risks and v) expose the convergences and divergences of perception between them. To achieve these objectives, a systematic review of the literature and a case study of a large project called New Cabo Branco Touristic Pole were built. As a result, it was possible to identify general characteristics of the literature on sustainability risks, bringing together and unifying several risks dispersed into four categories (socio-environmental, political, environmental requirements and organizational quality and strategic). Also based on the Systematic Review, it was possible to construct a new definition for the sustainability risk construct. From the case study, it was possible to extract an unprecedented analysis between convergence and divergence of perception of project stakeholders in relation to sustainability risks. The general results of the survey suggest that external stakeholders have more convergences than divergences between perceptions regarding risks. It was also possible to observe that the criticality indices of socio-environmental sustainability risks and environmental and quality requirements were considerably higher than the political ones, which should attract greater attention from managers of large projects in relation to these categories.

Mostrar Resumen
-
The evolution of the financial market over the years has made risk management increasingly important for financial institutions. Operational risk, in particular, is associated with existing losses at all stages of the operation. In this scenario, the management of this risk aims to minimize losses and contribute to stability in the economy. Although the notoriety of operational risks has been perceived by experts and researchers, there are still gaps regarding the analysis of the degree of importance attributed by the experts of financial institutions. Thus, the objective of this research is to determine the most relevant operational risks existing in a financial institution. To achieve the proposed objective, a mixed approach (qualitative and quantitative) was adopted, which begins with a theoretical conceptual framework, followed by an empirical study. In this research, a Systematic Review of the Literature was conducted, and a case study was applied in a credit union financial institution. According to the results of the literature review, the following stand out: the concern to reduce the minimum capital recommended by the Basel II Capital Accord; the chain reaction to operational risk and the great importance given to reputational damage. For the results obtained in the empirical study, the occurrences of 4 (four) types and 19 (nineteen) operational risk factors were identified. To hierarchize and calculate the degree of importance attributed by the respondents, a multicriteria decision support tool, the Analytic Hierarchy Process (AHP), was used, evidencing that the highest degrees of importance are related to people management, government policies, the physical security of agencies and the systems used by the organization. In addition, it was found the need to align the strategy of the cooperative studied, regarding the management of operational risks considered as priorities for each manager, in view of the assertiveness in the mitigation plans

Due to changes in lifestyle, supply of industrial products, production diversity, among others, traditional crafts need to develop their sustainable value through innovations. In this sense, sustainability in the context of crafts implies maintaining the operation of traditional artisans, through the development of creative products with local cultural identity, as well as constantly improving the creation process through innovation and design, obtaining profit to promote the economy. In this sense, design and handicraft can collaborate so that handcrafted products meet the needs of the contemporary consumer without losing the local identity and culture. This work aims to contribute to the process of creating handmade bobbin lace products that help artisans to meet consumer needs, preserve the cultural characteristic and traditional craft techniques. Initially, a Systematic Literature Review (SLR) was carried out in order to analyze how design and craftsmanship are addressed in the scientific literature in an integrated manner. The results of RSL point to the mutual benefits of integrating design with craftsmanship, creating identity and cultural value for craft products, adding value to the product and promoting local development. Research points to the growth of this theme and the academy as a possible catalyst for innovation in the craft sector. Then, multiple case studies were carried out with four communities of bobbin lace makers, using an adaptation of the Sustainable Value Exchange Matrix (SVEM), with the objective of analyzing how the perspective of business models for sustainability can contribute to enterprises crafts. The results show that some aspects of sustainability are already practiced by these enterprises, however some points still require greater investment, such as the development of new products, marketing, organizational culture and corporate governance, so that sustainability can be achieved. and its benefits. An action research was also carried out with Associação Rendeiras da Vila, with the objective of understanding the specificities of the process of creation and development of a collection using bobbin lace, seeking to identify the potentialities and limitations of this process. As a potentiality of the Association, the creative capacity and development capacity of different patterns of lace design and the quality of the lace stand out and, as limitations, the difficulty in receiving and specifying the demand, the management of projects, the elaboration of the budget, the high production time of the parts. With regard to the company, the following limitations were identified: lack of knowledge of the characteristics of production and handcrafted products, lack of specification of demand, proposal for highly complex molds, and the infeasibility of adhering to bobbin lace, due to its attribute of high cost. Finally, a methodology was proposed to assist in the creation and development of handmade bobbin lace products that meet consumer needs, preserve cultural characteristics and contribute to the maintenance of traditional craft techniques. The proposed methodology comprises 4 macro-phases: - Preparation, involves understanding the demand (briefing) and defining the problem; - Analysis, which comprises data collection and analysis, based on a list of requirements; - Creation, which comprises the elaboration of the patterns, creation of alternative lace designs and selection of the alternative and; - Project, which involves the elaboration of the model (prototype), technical data sheets and pricing. From the results and according to the literature about the problem raised, it can be concluded that it is possible to integrate the design technique with traditional handicraft techniques. Design can act as a catalyst, based on interventions, with the possibility of developing a new range of products combining natural handicraft techniques with designers' creation methods, resulting in creative products with local cultural identity.

Mostrar Resumen
-
Although Industry 4.0 (I4.0) has already been adopted by different organizations, companies still need instruments to assess progress. Thus, maturity models (MMs) are valuable tools for this purpose, but, for the most part, they are designed for manufacturing companies. However, the impact of I4.0 technologies is also visible in healthcare and is called Healthcare 4.0 (H4.0). The main objective of this dissertation is to develop a maturity model (MM) for H4.0. Specifically, it is intended to (i) identify levels, dimensions, and procedures of maturity models for Industry 4.0; (ii) analyze the particularities of the I4.0 concepts and technologies for health operations; (iii) analyze the adherence of the levels and dimensions of a maturity model for Healthcare 4.0 through the opinion of specialists; and (iv) apply the proposed model in public hospitals in the State of Paraíba. Through a systematic literature review (SLR), it was possible to identify levels, dimensions, and procedures used in MMs, making it possible to build a reference framework to help adopt or develop new maturity models. Then, research in the literature and other documents was carried out to identify the leading I4.0 technologies used in health services, and based on the I4.0 MMs, a MM for H4.0 was proposed, which was evaluated by specialists and subsequently refined. The refined model considered five levels of maturity (0 for nonexistent and 4 for advanced). The dimensions of the model were synthesized into three dimensions as enablers for H4.0, such as strategy, people, and organization, and the technology dimension as practices for H4.0 (Telemedicine, Internet of Things, Big data, Cloud computing, Autonomous robots, 3D printing, Virtual and augmented reality, Cyber-physical systems, Blockchain, Artificial intelligence, and Simulation). After refining the model, it was applied through case studies in two public hospitals in the state of Paraíba that showed different levels of maturity regarding H4.0. This dissertation advances in the literature since it proposed, refined, and applied a maturity model for H4.0, and it was not found in the literature consulted. In addition, the applied model can serve as a roadmap to identify the maturity level for H4.0, strategic factors, people management, organizational aspects, and H4.0 technologies, allowing a systemic view from the hospitals studied toward H4.0.

Mostrar Resumen
-
The reduction of defects in the manufacture of ceramic tiles is a challenge for the ceramics industry, seeking to meet the standards and quality criteria required by regulatory agencies and the consumer market. The standardization of colors among the ceramic pieces produced is of fundamental importance and to measure the color variation the spectrophotometer is used. Variation in any process can be associated with the production process itself or with the measurement system used. This work presents a series of analysis studies of measurement system (MSA) of hue of a ceramic production process. Thus, this dissertation aims to minimize the sources of variation in a process for measuring the hue of ceramic tile tiles through stability, capability and optimization studies. A capability analysis was developed evaluating the Cpk index of the production process focusing on the shade variation between ceramic pieces. A repeatability and reproducibility (GR&R) study was carried out and the need for improvements in the measurement system was observed. Thus, a Type 1 study was carried out and optimization was performed using the desirability method based on the Cgk index. The results obtained indicated an optimal setup formed by a template for centralizing the measurement, performing previous cleaning of the part, optical aperture of the spectrophotometer at 6mm and consideration of a value per measurement. In addition, the temperature of the part proved to be a significant factor for measurement variation.

Mostrar Resumen
-
In Brazil, the weight of courses has a direct impact on the equivalent student formula, as well as on the
resource allocation process. Considering that the weights per group used in Brazil were based on the
same structure used for courses in England, considering the impact that these weights have on the cost
indicator and on the distribution of resources in federal universities in Brazil, this study aims to analyze
the adherence of the weights, used in England until the year 2018, in the attribution of weights per group
of courses in Brazilian federal universities. This work was developed in four chapters in the format of
scientific articles. In article 1, a survey of the state of the art was carried out using the systematic review
method, which guarantees greater reliability and reproducibility. The methodology used for article 2 was
action research, which can be understood as a research method and also a strategy for conducting
qualitative and applied scientific research, of a participatory nature, with the objective of seeking a
collective solution to a given problem-situation. Canada is represented by both incremental funding and
student fees. Analyzing England's educational system it was possible to notice that it is totally focused
on the student's vocation, while in Brazil, despite the concern with vocation, the main focus of the system
is on the professionalization of these students. The intentions coincide with respect to formula financing
but diverge in spending on higher education, which in the case of England is less than 1% of GDP. The
results showed that although some countries have been grouped by similar characteristics, in the analysis
performed in this study, it is noted that higher education in each country has its specificities, for this
reason the use of financing structures that are based on the reality of education in other countries needs
to be analyzed, since they must take into account the uniqueness of each system

Mostrar Resumen
-
The civil construction industry plays a significant role in the economic and social aspects of the country. For this reason, it is responsible for high rates of accidents at work and is considered one of the most dangerous industries. The scientific literature shows that projects may be related to the occurrence of these accidents. Therefore, designers can contribute to the reduction of these rates through the concept of prevention through design (PtD), which consists of anticipating and eliminating worker safety risks in the design phase in order to prevent the occurrence of accidents at work throughout the life of a building. The literature obtained on PtD in Brazil reveals the lack of studies that address this theme and, specifically, the implementation of PtD in the civil construction industry, revealing that this is a promising area for research. Thus, the present study sought to investigate the knowledge and application of good PtD practices by civil engineers from civil construction companies in the city of João Pessoa-PB-Brazil. To achieve this objective, in Article 1, a Systematic Literature Review was carried out, using the Web of Science database, in which it was possible to identify 58 good practices that can be used to implement PtD in building projects in civil construction, as well as thirteen potential barriers that may hinder its implementation. Subsequently, in Article 2, a multiple case study with twelve civil engineers who work in the execution phase of works for six construction companies was carried out to verify the engagement of these professionals regarding the use of good PtD practices and to analyze their perception of the degree of importance and impact of using good practices in the phases of the construction cycle, as well as the barriers that may affect their use. In this second article, it was possible to verify that the majority (83%) of the professionals did not have knowledge about the concept of PtD, but they showed interest in knowing it, showed a high interest in using good practices and agreed that its implementation would be important for the workers' safety. As for the phases of the construction cycle, they pointed out that the execution phase of the works would be the phase most impacted by the implementation of good PtD practices, and that the lack of knowledge about work safety and the lack of collaboration between work engineers and designers in the project elaboration phase can hinder the adoption of PtD. From this study, it is expected to contribute to the advancement of knowledge about PtD in the scientific literature by making available the list of good PtD practices and serve as a reference for designers to consider worker safety in their projects, and allow both them, as well as site engineers and construction companies, to be aware of the influence that design decisions have on impacting safety conditions in work situations.

Mostrar Resumen
-
The Water-Energy-Food Nexus (WEF Nexus) approach stands out for its ability to consider interdependencies between resources at a variety of spatial scales that may be overlooked in a single disciplinary approach. Food, energy and water security are inextricably interdependent and require integrated management of the three sectors through cross-sectoral coordination. To this end, tools have been developed to support the WEF Nexus evaluation teams. These tools need to be adapted to capture the stakeholders' concerns, have feasibility in practice and flexibility to reflect the local conditions in a specific area. Agriculture is one of the key sectors of WEF Nexus. In order to contribute to this research topic, the overall objective of this dissertation is to propose a systemic and participatory approach tool to assess water-energy-food (WEF) Nexus interactions in the context of family farming. Initially, it was identified, through systematic literature review, a set of potentialities and limitations that should alert evaluations in future studies. Among the methods studied, the method Evaluation of Natural Resource Management Systems incorporating Sustainability Indicators (MESMIS) has the capacity to support participatory sustainability assessment at small scales. As a result, the MESMIS-Nexus systemic and participatory approach tool is proposed to assess WEF Nexus interactions on farms. This tool provides an application capable of capturing the perception of stakeholders in the conducted assessments and making the systemic interactions of the approach explicit. The tool is applied to seven family farms, in real cases, aiming to evaluate the systemic interactions of WEF Nexus in the perception of family farmers and enabled to identify four practical lessons for the studied context.

Mostrar Resumen
-
Renewable energy sources are essential for the sustainable development of nations. In investments in renewable energy, it is often necessary to make decisions based on perspectives that may conflict with each other, characterizing a multi-objective problem, which is naturally seen as complex. In addition, there are a series of risks linked to the intermittency characteristic of renewable sources and the high investment cost, highlighting the need for methods that can support the decision-making process. Hybrid generation and the use of energy storage systems are pointed out as solutions to the challenges in the implementation of renewable sources. Given the above, the general objective of this dissertation was to propose multiobjective models through economic and environmental perspectives, in hybrid wind-photovoltaic systems with the use of batteries, on a residential scale, using the white tariff modality. The Design of Experiments (DOE) method was used to model the objective functions of the developed models, which used the NPV, LCOE and Greenhouse Gas - GHG indicators as response variables. The Desirability and Normal Boundary Intersection (NBI) methods were used to optimize the models developed in the research. The main results indicated that the hybrid generation can, in some geographic regions of Brazil, bring great economic and environmental benefits. This is due to the complementary nature of energy sources, despite wind energy having a higher investment cost. The use of batteries manages to strongly support the implementation of renewable energy, despite its high cost, which is one of the reasons for the economic unfeasibility in some regions of the country. The need to implement incentive policies is evident, mainly related to wind energy and batteries, bringing benefits not only to investors, but also advantages associated with the decentralization of electricity generation.
