The use of seed banks has been widely used in ecological recovery projects around the world. The soil seed bank includes all viable seeds present in the soil or litter. To evaluate the composition of soil seed banks as an indicator of recovery in agroforestry systems. 128 samples were collected, 64 soil samples and 64 litter samples. The collection and storage of the seed bank considered the number of individuals. The arboreal survey considered quantity and diversity. The results of the analyzes made it possible to understand the interactions and adaptation of species to the environment, taking into account that all the information obtained is valuable and will serve as strategies for the conservation and management of SAFs. Information that may contribute to soil recovery in the future. In addition, it contributes to sustainable agricultural practices and the better management of these systems. Analysis of seed banks revealed that agroforestry systems play an important role in conserving biodiversity. It was possible to see that initially the herbs will colonize in the seed bank. However, seed bank analysis is just an evaluation tool and needs to be combined with other recovery practices. To better understand the seed bank as an indicator of recovery in SAFs, research will be needed to thoroughly study the composition of the bank.

The primary aim of the present study was to investigate the evidence for breathing as an intervention alone or in addition to PFM contraction in treatment of UI and POP. Materials & Methods This systematic review included short-term experimental studies and randomize controlled trials (RCTs) indexed on PubMed, EMBASE, and PEDro database. A form was used to extract data that was analyzed qualitatively due to the heterogeneity in interventions and outcome measures of the included studies. The individual methodological quality of RCTs was analyzed using the PEDro scale. Results A total of 18 studies were included, 374 participants from short-term experimental studies and 765 from nine RCTs. PEDro score varied from 4 to 8. Activation of the PFM during expiration was significantly less than during a PFM contraction. In general, the RCTs showed that training the PFM is significantly more effective to improve PFM variables and UI and POP than breathing exercises, and that adding breathing exercises to PFMT have no additional effect. Conclusion This systematic review indicates that the evidence for incorporating breathing exercise in clinical practice in addition to or instead of PFMT is scant or non-existing, both based on short-term experimental studies and small RCTs.

Heart failure (HF) is a state in which the heart is no longer able to meet the circulatory needs of the body, being the consequence of most diseases of the cardiovascular system and one of the main reasons for mortality, hospitalizations and impaired quality of life. There are several therapeutic strategies through the use of drugs or medical devices that aim to reduce mortality caused by cardiovascular diseases (CVDs). However, the magnitude of the benefits of physical training programs carried out in different scenarios is not yet well elucidated in the literature, including training based on the presence of a physical education professional within heart failure clinics, performing non-prescription exercise supervised compared to a supervised face-to-face training program or telerehabilitation. Furthermore, it is known that impairment of cardiac function assessed by echocardiography can adversely impact the exercise tolerance of patients with HF, making it important to detect echocardiographic variables capable of detecting low functional capacity in these patients. The work was divided into two studies with the objective of detecting echocardiographic variables with good accuracy for low exercise tolerance in patients with heart failure with reduced ejection fraction (HFrEF) and comparing the effects of physical training with supervision, without supervision and telerehabilitation with supervision on function cardiovascular disease, functional capacity and quality of life (QoL). Study 1 was a prospective cross-sectional study involving 50 patients, mean age 62 ± 11 years, 65% men. There was an association between diastolic function variables E’ Mitral Septal (R = 0.55 and P < 0.001) and E/E’ Mitral (R = 0.30 P = 0.031) with shorter distance in the 6MWT and impaired QoL. E’ Mitral Septal, adjusted for a model of age and ejection fraction, was an independent marker of poor exercise tolerance (R=0.57; p<0.001). The ROC curve showed the cutoff E’ Mitral Septal < 5.8 cm/s with A/C of 0.74 [CI: 0.60-0.88; p=0.01], sensitivity of 68% and specificity of 79% for the shortest distance covered in the 6MWT. Thus, E’ Mitral Septal, in the considered sample, has good accuracy for detecting low exercise tolerance in patients with HfrEF. Study 2 was a longitudinal clinical trial with a sample of 18 patients divided into 3 groups. There was no difference between groups in relation to pre-intervention characteristics, with the final sample comprising 55% males, with a mean age of 62 ± 12 years. There was an improvement in left ventricular ejection fraction (LVEF) (P=0.002), in the distance covered in the 6MWT (P<0.001) and in QoL (P<0.001) considering the effect of time. There was interaction between time and group in skinfold values for muscle groups: biceps (P=0.04), triceps (P=0.01), chest (P=0.05) and thigh (P=0.01; P=0.03). There was a significant association between improvement in the distance covered in the 6MWT and in QoL (R=0.53; P<0.001). A favorable impact of physical training on cardiac function, exercise tolerance and QoL was observed in patients with HFREF. Regarding the comparison between the groups, although the sample is limited, no significant difference was observed between them.

TIG welding processes are widely used to join metallic materials of different thicknesses, such as stainless steel. These are processes used in different segments of the industry, highlighting in the metallurgical area the linear and circumferential welding in pressure vessels applied in the solar heating system. Metallic tanks used for water storage are generally made of 304 or 316L stainless steel plates, calendered and welded using the TIG process. TIG welding parameters such as arc length, welding speed, gas flow and welding current are critical, influencing process characteristics such as: joint quality, profitability, welding cost, etc. Scientific articles from journals in the area of mechanical engineering, materials and welding metallurgy were reviewed. The main focus was to seek information about methods, processes and analyzes through material tests for characterizations of manual TIG welding in thin stainless steel plates. The main objective of this research is to develop an evaluation methodology through the characterization of the weld beads between the body and tops (manual welding) of Solis pressure vessels.

Epidemics can significantly affect animal production and generate large economic impacts. Furthermore, current practices for treating and controlling infectious diseases in farmed animals do not always show the desired effectiveness. In these cases, the quantitative genetics offers a viable alternative through the study of genetic variations of host characteristics that affect disease transmission, especially susceptibility, and infectivity. However, despite advances, the challenge to estimate genetic effects that mainly control infectivity continues to exist. Therefore, the general objective of this thesis was to contribute to the state of the art in the development of statistical models that can capture the dynamics of transmission of infectious diseases and consequently improve the estimation of genetic effects on infectivity. We present a new version of the dynamic non-linear indirect genetic effects model (dnIGE) and an inferential method to estimate its parameters. Our methodology includes a covariance structure on the distribution of genetic and environmental effects of susceptibility and infectivity, which were previously considered independent and uses modern Bayesian inference to estimate the genetic effects and heritabilities associated with these traits. Results show that the extended dnIGE model can accurately estimate heritabilities and genetic values associated with susceptibility and infectivity, even when there is a genetic correlation between these traits. Our proposed methodology offers potential impacts in areas such as disease control in livestock through selective breeding and also in predicting and controlling the emergence of disease outbreaks in human populations.

Metallic glasses exhibit exceptional properties such as high mechanical strength, thermal stability, and excellent magnetic properties. In this study, our aim was to develop a high corrosion and wear-resistant metallic glass from pig iron, a ferrous alloy with high impurity content and low added value. Two alloys, Fe68Cr8(C,B)24 and Fe62Cr8Nb4Mo4(C,B)22, composed of pig iron and commercially pure elements, were produced using an electric arc furnace. The alloys were processed via melt-spinning to obtain metallic ribbons and through centrifugal casting into copper molds to produce 1 mm thick plates. Characterization of the alloys involved X-ray diffraction, exploratory scanning calorimetry, scanning electron microscopy, transmission electron microscopy, Vickers microhardness, electrochemical, and tribological tests. While the alloys processed by centrifugal casting did not vitrify due to slower cooling rates, they exhibited high hardness, surpassing 1000 HV, resulting in significant wear resistance. On the other hand, the Fe62Cr8Nb4Mo4(C,B)22 alloy produced by melt-spinning successfully formed a fully vitrified structure. This vitreous nature was confirmed through X-ray diffraction, including synchrotron radiation, and transmission electron microscopy. The glass transition temperature was approximately 553°C, with crystallization initiation at 574°C and a supercooled liquid region of 21°C. The Fe62Cr8Nb4Mo4(C,B)22 alloy demonstrated higher hardness compared to pig iron (1070 vs. 666 HV0.1, respectively) and greater stability in chloride-rich environments than the stainless steel 444, as evaluated by the passivation window before pitting corrosion (1253 vs. 738 mV, respectively) and easiness of re-passivation during the reverse scan. These results contribute to the production of resistant, hard, and cost-effective metallic glass alloys capable of meeting demanding applications.

With the increase in Brazilian public policies on Special Education from the Perspective of Inclusive Education, enrollment of public students in Special Education has been growing at different levels and stages of education. The same occurs with these students' access to the final years of Elementary and Secondary Education in regular education institutions. In this scenario, questions arise about guaranteeing participation, learning and success. One of the supports suggested by the literature to ensure the necessary conditions for the schooling of Special Education students, especially those with disabilities, has been individualized planning. This process requires collaborative strategies involving different members of educational institutions based on a comprehensive assessment of the student with disabilities in a collective decision-making process that will result in a written document. As it is a device yet to be provided for in Brazilian legislation, as is the case in many countries, educational spaces have many doubts about how to prepare the Individualized Educational Plan (IEP). Thus, the central question in this study is what an Individualized Educational Plan (IEP) protocol would look like that would contribute to favoring educational policies for the permanence, progression and transition to adult life of people with disabilities. The study's general objective was to develop and validate a protocol for preparing the Individualized Educational Plan (IEP) for students with disabilities in Basic Education. The specific objectives were: a) Compile and systematize an IEP protocol based on proposals found in practice and specialized literature in the area; b) Validate the content and semantics of the IEP protocol items with two groups of different judges: professionals and academics from the area community; c) Produce an improved and validated version of the IEP protocol. The research uses a qualitative approach based on the Design Science Research (DSR) method, adopted in education to create prototypes or educational products. In the first validation stage, 106 participants (professionals and members of Brazilian Federal Institutes) contributed to this research. In the second stage, 14 researchers in the field of special education contributed. Data was obtained through questionnaires on Google Forms. Participants were invited to rate the relevance and vocabulary of each item in the protocol. The items were analyzed quantitatively and qualitatively. The results were procedural and specific at each stage, resulting in a protocol built based on literature and evaluated by different judges called ProPEI. The ProPEI is a broad document to be completed by different hands after reflection and sharing ideas. The document was structured with the following fields: 1. Information from the educational institution; 2. Authorization term for preparing the IEP; 3. Student profile (individual characteristics, skills and challenges); 4. Characterization of the family and their expectations regarding the student’s development; 5. Information about the previous schooling process; 6. Description of the student's initial repertoire; 7. Characterization of team members; 8. Distinction of areas of knowledge that require adaptation or differentiation processes in teaching; 9. Establishment of specific learning objectives (short, medium and long-term goals); 10. Development of teaching strategies and teaching materials; 11. Necessary adjustments in the student's teaching and learning evaluation process; 12. Definitions of dates to monitor the student's trajectory and the adequacy of the IEP. The participants who evaluated the protocol consider it a document with great potential to contribute to the school's inclusion of students who need it. It is expected that this study and the protocol developed in it will contribute to the elaboration of the IEP as support to guarantee the promotion of practices that favor the participation and learning of students with disabilities in schools.

Theoretical debates on patient quality and safety have been widely discussed, but fewer studies have focused on educational activities for healthcare professionals in this context. The training of these professionals is essential in promoting safe care and preventing adverse events. Investing in patient safety education is a strategy to achieve harm-free healthcare. However, healthcare services face challenges in implementing the National Patient Safety Program and ensuring quality care. Therefore, it is important to identify the scientific literature that evidences the state-of-the-art educational activities for patient safety. Objective: The objective of this study is to map and present the scientific literature on educational activities focused on patient safety, developed with healthcare professionals and undergraduate students in Brazil. The basic themes of the National Patient Safety Program will be considered. This will be done through a scope review. Methods: The theoretical frameworks were selected through a literature review, following the scoping review method and the protocol of the Joanna Briggs Institute. The consulted databases included the National Library of Medicine (PubMed), the Latin American and Caribbean Center on Health Sciences Information (BIREME), the Scientific Electronic Library Online (Scielo), Web of Science, the Cumulative Index to Nursing and Allied Health Literature (Cinahl), the Education Resources Information Center (ERIC), and the multidisciplinary database (Scopus). National and international publications in English, available online and published from 2013 onwards were selected. A total of 1422 records were found in the searches, and a selection of 12 research articles including theses, dissertations, and scientific papers, were presented in the flowchart of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Prisma) recommendations. The selected studies were organized in tables, presenting information such as number, author, year of publication, Brazilian region, study type, study objective, participants, theoretical framework, educational intervention goals, National Patient Safety Program theme addressed, course content, educational strategy, instructional resource, intervention duration, and outcome level according to the Kirkpatrick method, as well as the institution promoting the educational activity. Results: The Brazilian regions that published the most studies on educational activities for patient safety were the South and Southeast. The studies presented various methods, with experience reports being the most frequent. Regarding methodology, qualitative approach was the most utilized. The nursing team (nurses, technicians, and nursing assistants) was the predominant population in the studies. The main findings regarding the most utilized educational strategies were realistic simulation and problematization. The most addressed themes of the National Patient Safety Program were healthcare-associated infection and safety in prescription, medication use, and administration. Conclusions: This review allowed the identification of critical factors for the development and improvement of educational interventions related to patient safety, adherence to the main protocols of the National Patient Safety Program, as well as gaps in educational interventions regarding effective communication and the importance of evaluating trainings, as well as measuring their impact on healthcare.

Two cobalt(III) complexes containing different β-ketoesters, namely [CoIII(L1)(py2en)](ClO4)2⋅H2O (1) and [CoIII(L2)(py2en)](ClO4)2 (2) (py2en = N,N′-bis(pyridin-2-ylmethyl)ethylenediamine; L1¡ = methylacetoacetate; L2¡ = ethyl 4-chloroacetoacetate) have been prepared and investigated as prototypes of bioreductive prodrugs. The presence of β-ketoester and py2en ligands in 1 and 2, as well as the perchlorate counterions, was supported by IR spectroscopy and CHN elemental analysis. The composition molecular structure of both complexes was confirmed by NMR spectroscopy and ESI mass spectrometry. Structural information was also obtained for 2 via Xray diffraction analysis. The redox properties indicate that 1 and 2 are suitable for reduction under biological conditions. Investigation of DNA-interacting suggest that 1 and 2 bind DNA via electrostatic forces. Both complexes may be employed as possible platforms for the delivery of biologically active compounds, since their reaction with ascorbic acid in PBS at pH 6.2 and 7.4 at 37◦C results in the release of the β-ketoester ligands upon Co(III)/Co(II) reduction.

Lawrence Markus, a well-known mathematician, published, in 1954, a strong result about classification of planar vector fields. Afterwards, Dean Arnold Neumann generalized such work for continuous flows, and the result became known as the Markus–Neumann Theorem. Recently, in 2018, José Ginés Espín Buendía and Víctor Jiménez López wrote a paper exposing gaps in the two aforementioned articles. We present here a discussion on these classical results of classification of planar vector fields and continuous flows, going through the three cited works and elaborating on definitions, examples and proofs.

Faced with the problem of a small supply of services and a considerable rate of evasion of users of a Psychosocial Care Center for Alcohol and Other Drugs, the purpose of this study is to carry out a survey of the affections that the CAPS AD environment awakens in users, observing the configuration of the person-environment relationship and the psychosocial implications provoked by the experiences lived in the service. In the light of studies in Environmental Psychology and the field of Collective Mental Health, from an expanded clinical perspective, the study is justified by promoting advances in deinstitutionalizing practices, gaining knowledge and enabling greater conditions for identification, appropriation and belonging to the environment. It aims to analyze the perceptions that the environment awakens in the user, based on affectivity, in a Psychosocial Care Center for Alcohol and Other Drugs. The study methodology follows a qualitative design, characterized as an intervention research, in which the Instrument Generating Affective Maps (IGMA) was applied, together with structured interviews, whose results are examined with the support of Categorical Content Analysis. As a result, it was inferred that the user's relationship with the CAPS AD presents a potentiating esteem and feelings of those who are at home, of those who feel welcomed. No correlation was identified between affectivity and the environment and dropout from the service, and the evaluation of therapeutic practices obtained a majority result of satisfaction, followed by indication of improvements regarding the expansion of the offer menu of non-biomedical model activities, the shortening of the waiting time for medical return and investments in structure and therapeutic resources.

The Vassununga State Park (PEV), in the municipality of Santa Rita do Passa Quatro - SP, is a State Conservation Unit, possessing vast diversity in fauna and flora, composed of formations of Atlantic Forest (Semideciduous Seasonal Forest) and Cerrado, characterized as a transition area between these biomes. Its stratified composition in several plots and history of exogenous disturbances have propitiated an increase in the population of vines. In this work, we evaluated possible changes in forest structure, litterfall and soil chemical attributes of semideciduous seasonal forest in edge areas after six years of management by annual cutting of vines. Twenty-seven (10x10m) plots were marked near the edge, 14 of them in areas that did not receive any management, control (C), and another 13 that underwent an annual vine cutting (M) during the dry season. Samples of literfall and soil were collected to assess differences in dry mass and soil chemical attributes. Forest and literfall structure did not differ significantly in managed and unmanaged plots. However, it was possible to verify chemical changes in the managed soil, such as doubled Al content (from 4.9 mmolc/dm3 to 9 mmolc/dm3), lower pH (from 4.7 to 4.5), and lower organic matter content (~10%), suggesting a change soil.

Steel-concrete composite connections are those in which the transfer of forces between structural elements, as well as stiffness and strength, are simultaneously ensured by steel and concrete components and elements. At room temperature, the behavior of steel-concrete composite connections is well known. However, the behavior of these connections in fire situations and their effects on the structure still need to be further investigated. This study investigated, through numerical analyses, the behavior of beam-beam and beam-column composite connections in steel and concrete, both at room temperature and in fire situations, as well as their effects on the overall structural behavior. Initially, a bibliometric analysis and subsequent systematic review of the literature regarding studies involving steel-concrete composite connections in fire situations were conducted to identify the main knowledge gaps in the field. Subsequently, numerical models of steel and steel-concrete composite connections were constructed and validated under both room temperature and fire conditions. Subsequently, a parametric analysis was conducted, simulating 663 numerical models of composite connections under both ambient temperature and fire conditions. The variables under study encompassed connection type, beam and column profiles, negative reinforcement ratio of the composite connection, degree of steel-concrete interaction between the composite beam and slab, slab type, direction of moment curvature at the connection, steel strength, and concrete strength. All parametric variables exerted influence on connection behavior. Fire conditions revealed distinct failure mechanisms compared to those observed under ambient temperature for all connection types. Practical equations were formulated for calculating moment resistance and initial stiffness at ambient temperature, as well as minimum stiffness during a fire and cumulative rotation variation, specifically for beam-column composite connections. Subsequently, to evaluate the impact of connections on the fire behavior of structures, 8 building models were constructed. In these analyses, significant influence of the number of stories and fire location on building behavior was observed. Moreover, the fire resistance duration of the buildings exceeded that of isolated connection models, reinforcing the importance of considering the global behavior of structures, along with proper interactions among elements, in fire situation design.

Based on the analysis of the feature films A Girl at My Door (2014) by Jung July, Missing (2016) by Lee Eon Hee and Kim Ji Young, Born 1982 (2019), this study focuses on observing the feminist discourse of South Korean female directors from three perspectives: sexuality, motherhood, and work. We established relationships between the theory of melodrama and han (恨); using feminist film theory, we analyzed the Confucian concepts of the three obediences (三從之道); the seven sins (七去之惡) and the wise mother, good wife (賢母良妻) present in the selected works. We displayed in an introductory way the history of cinema in the Korean peninsula in parallel with the main political events of the 20th century; and the participation of women in the development of East Asian cinematographic language. For example, Park Nam Ok portrayed in The Widow (1955) the difficulties of a widow raising her daughter during the war. Like her, other female directors have also used cinema to show the gender inequalities faced in South Korea. In this thesis, we sought to answer the current challenges faced by female audiovisual directors.

This work investigated how Professional and Technological Education Professors experience vertical education at the Federal Institute – Campus Itapetininga. The methodological approach of the research was configured from the Historical-Cultural Theory, specially in the "experience" concept proposed by Vigotski (1995, 2000, 2001). Data come from three primary sources: systematic mapping, document consultation, and interviews with professors. The results indicate that teaching is a profession that is constituted for the participants through their personal and professional experiences and their relationship with students and co-workers, enabling professional development. Training is considered necessary, but greater importance is given to previous experiences/knowledge in vocational training and sharing experiences with peers. Verticalization is understood as a formative itinerary between high school and graduate school, covering specificities in the different levels of education, difficulties, potentialities, and tensions resulting from this process. Concerning teaching at the Federal Institute, good working conditions are highlighted, such as remuneration, infrastructure, class hours, research and extension activities development, and positive relationships with students and colleagues. However, a few difficulties related to the verticalization of teaching in the IF are addressed, which, in general, are seen as a potentiality of the educational work. The teachers' experiences rescue subjective aspects and significant situations in professional practice. The investigation presents a proposal for a training path for these teachers. This work develops the "multifaceted teaching" concept, which seeks to portray the complexity of vertical teaching work in Federal Institutes. The study shows the training needed for Professional Education teachers, carried out in a planned and systematic way, and discusses the importance of the professional induction period in the EBTT teacher's career and collective spaces for continuing education, considering the teaching role in this vertical process.

The anti-asylum movement is a social and political movement that aims to transform the mental health care model, overcoming the asylum logic, which involves the isolation and exclusion of individuals with mental disorders in psychiatric hospitals. In this perspective, studying the impact of the anti-asylum movement on new public mental health policies presents a relevant topic to foster a debate aimed at promoting equality, well-being, and social inclusion of individuals with mental disorders. The methodology adopted involved conducting a literature review. It is concluded that the Anti-Asylum Movement in Brazil represents a highly relevant social and political movement in the pursuit of guaranteeing human rights and the dignity of individuals with mental disorders. Regarding public mental health policies, it is necessary to strengthen them, invest in the training of qualified professionals, and promote awareness and sensitization of the population regarding issues related to mental disorders.

This dissertation reports on an investigation carried out within the Group of Studies and Research on School Organization: Democracy, Human Rights and Principals’ Training – DEFORGES, having as its theme school leaderships in a public-school democratic administration perspective. The general objective was to map out scientific productions on school leadership in Brazilian basic education to identify possibilities for strengthening schools’ democratic administration. The specific objective was to analyze and systematize its theoretical references, methodologies, and results. The guiding question was: how are school leaderships configured in Brazil, based on the scientific production found in Brazilian digital databases, regarding strengthening the public schools’ democratic administration? From a methodological point of view, this was a qualitative, descriptive, and analytical meta-study. The databases consulted were the CAPES Journals, Theses and Dissertations Portal, the Brazilian Digital Library of Theses and Dissertations – BDTD and the Google Scholar search engine, in the time frame from 2018 to 2022. The corpus of analysis comprised 18 works – 10 articles, six dissertations and two theses, which were selected through bibliographical research procedures, with analytical syntheses being elaborated for each one of them. Then, the sections dedicated to the metamethod, meta-analysis and metatheory were developed, the latter using the technique of content analysis of the data, for which the MAXQDA 22 software was used. The analysis of the corpus enabled an advance in the theme of school leaderships, present in some works, with democratic assumptions, that is, of collective participation, decision distribution of and awareness of those involved. In this democratic context, school leaders can emerge in all school segments – in addition to the administrative one, as it was evidenced in this dissertation, including teaching leadership.
