The present work is characterized in an exploratory qualitative study, gathering analysis of narratives published in cyberspace of women who underwent home births. At narratives were analyzed based on studies of occupational therapy in everyday life. looking for the marks of daily life that influence this event, having as objective to identify and analyze situations in the daily lives of women present at the moment of childbirth and its effects on the process of giving birth, strengthening the role of women. For this, in the context of a qualitative research, we started from the method of cartography of reports from childbirth available in cyberspace. The results point to the different ways in which the daily life of the mother, family and home can produce transformations in the process of childbirth. The action of giving birth at home converges and is expressed in the body's relationships and choices of the parturient with people, objects, environments, feelings and professionals.

Abstract: Since its inception, occupational therapy has been interested in the exclusion experienced by populations that historically are on the margins. Among these, it is possible to cite a figure that circulates through the various frontiers of society: the foreigner. This work aimed to analyze the main challenges of changing the cultural context, in the face of migration motivated by political, economic and environmental crises, examining the relevance of the occupations of these subjects in their process of adaptation to a new culture. The research had a qualitative character and used interviews to access the life history of Haitian immigrants, who sought Brazil as a place to start over. The reports show the importance of paid work in social inclusion, as well as the need to discuss the creation of public policies and the articulation of support networks, to guarantee an effective inclusion of these immigrants to Brazilian society through access to a dignified life.

This Scientific Technological Initiation project is involved in the relationship between the demands of the homeless population, the recent integration of social policies and the contribution of promoting social practices and technologies, in the themes of social fragmentation and the processes of social vulnerabilities. Therefore, it proposes to contribute to the analysis of data collected by the 1st Census carried out with the homeless population in the city of São Carlos - SP, carried out in 2019, whose focus will be data related to the daily lives and ways of life of people who find themselves in that situation. The answers were tabulated and systematized using the Excel Office® software, so that graphs and tables were built for analysis, organized into four stages. Throughout the study, it was possible to build the profile of the participants, analyze their ways of life and identify inequalities among the participants, such as the high frequency of people on the streets, low adherence to public facilities and the absence of work in their daily lives. For these underprivileged daily lives, social technologies were proposed, based on the expertise of Occupational Therapy, as strategies that respond to the real needs of this group.

A matriz energética elétrica brasileira vem se alterando com a ajuda de programas de incentivo a energias renováveis, buscando menores custos e um ganho maior com bem estar social. Assim faz-se necessário a integração de fontes de energia alternativas às convencionais na resolução de problemas de despacho econômico, que tem por objetivo encontrar o ponto ótimo de alocação de energia em um sistema de potência. Esse problema pode buscar tanto minimizar custos, quanto maximizar lucros ou o ganho social. O presente trabalho busca desenvolver um método para encontrar a função custo de geração eólica para aplicação em um despacho ótimo buscando maximizar a função bem estar social na produção de energia eólica. Esse método procura caracterizar as curvas de velocidade de vento a partir da função de densidade probabilidade de Weibull para que possam ser considerados os aspectos incertos da produção de energia eólica ligados à superestimação e subestimação de potência eólica disponível, assim como estimar o custo de implementação de um complexo eólico e de manutenção do mesmo. Portanto é feito um estudo de caso com um sistema de 6 barras sendo três de geração e três de carga chegando no valor ótimo para o preço da energia que pode ser utilizado para valoração dos contratos do PROINFA para geradores eólicos.

The history of indigenous population has been marked by tragic epidemics of infectious and parasitic diseases and in 2020, with the pandemic of COVID-19, the political, social and environmental vulnerability of these populations is even more evident. Therefore, it is considered essential to know the scientific production about these populations considered vulnerable due to their space and socio-cultural expropriation and how close it is to the priority needs of health care. This study is justified in the sense of contributing to identify knowledge producers in research on indigenous health, providing evidence of institutional centrality and the possibility of greater investment in research in indigenous health. The Science, Technology, Society field allows us to analyze aspects that provide this construction: who researches, what is researched and for whom it is researched. Thus, the research has as its general objective to map and quantify the scientific activity in Brazilian indigenous health through bibliometric methods considering the year of publication, journal, author and keywords. As for the methodological procedures, it is classified as descriptive with a quantitative approach. The informational source chosen for the research was the Virtual Health Library Brazil, which is an integral part of the Virtual Health Library for Latin America and the Caribbean and to assist in the organization of the data, the StArt tool was used. From the search strings used in the VHL Brazil portal, 1083 articles were identified; after reading the articles and predefined inclusion and exclusion criteria, 126 articles were kept for analysis purposes. For the discussion of articles from the perspective of Science, Technology and Society, it was considered important to indicate: indigenous cultural issues on each theme; change in habits and aspects related to technologies. The year indicator showed considerable growth only in 2014, with more periods of stability than growth or retraction of publications. The periodical indicator presented the Public Health Notebook with the largest number of publications. Regarding the author indicator, the one that most published in the analyzed period was Santos, Ricardo Ventura. And from the indicator of the keywords of the articles, it was possible to find out which themes were most addressed in the period from 2010 to 2018 and they are: oral health, followed by women's health, tuberculosis, nursing and surveillance and nutritional status. As a limitation of the research, in order to better understand the scientific progress in relation to the recovered targeted subjects through the StArt tool research, it should be pointed out the need for an analysis of the articles in relation to the methodological issues; it would also be interesting to expand the study to books, theses and dissertations and scientific events. In addition, it was observed that the theme of women's health has 4 lines of research in the Research Priority Agenda of the Ministry of Health, which would be a specific theme to be studied in new research.

The present work aims to investigate the web post buckling resistance of composite cellular beams. For this task, geometrical and physical non-linear analyses are developed in the ABAQUS® software. The computational model was calibrated considering physical models of composite cellular beams, with steel-concrete composite slabs, and steel-concrete composite beams with precast hollow-core slabs. Subsequently, the numerical models were unified to represent the composite cellular beams associated with precast hollow-core slabs. Two parametric studies were carried out, varying the cellular beams key parameters, such as the web-post width and the opening diameter. The first study evaluated the floor systems, considering steel-concrete composite and precast hollow core slabs. The second study investigated the composite action, varying the spacing, with one and two connecting lines, between the shear studs. In the first study, considering the section with double symmetry and precast hollow core slab, the predominant failure mode was web post buckling. For the section with asymmetry, the predominant failure mode was the combination of the plastic mechanism with the web post buckling accompanied (or not) by the shear stud rupture. In the analysis of the type of slab it was found that the composite cellular beams with precast hollow-core slabs presented greater resistance. The results of the first parametric study showed that the resistance of the composite cellular beams was not limited only by the resistance of the cellular profile, but also, of the slab, due to the shear resistance. On the other hand, in the second parametric study, a drop in global shear resistance was observed due to the absence of shear studs above the second opening, close to the support. The numerical models of composite cellular beams with hollow-core slab and concrete topping presented greater global shear resistance than the models without concrete topping. However, for those models with concrete topping, there were a greater number of observations in which the shear studs rupture occurred. Finally, the results of the second study were compared with a proposed equation, which takes into account the global shear resistance due to web post buckling, Vierendeel mechanism and composite action. The proposed analytical model showed an excellent correlation with the results of the numerical analyses, especially for the models in which the combination of the web post buckling with the plastic mechanism was identified.

There has been exponential population growth and, consequently, an intensification in the use of fertilizers. The overuse of fertilizers generates environmental impacts, due to the leaching and volatilization of fertilizers, which can contaminate soil and water. One of the ways to minimize these impacts is to use enhanced efficiency fertilizers which allows the proper use of nutrients according to the demand of the plants, reducing both the environmental and economic impact. Additionally, the use of materials from natural sources and with potential for biodegradation contributes to the sustainability of system. In this work, tablets of enhanced efficiency were developed, composed of clinoptilolite zeolite matrix adsorbed with macro (K) and micronutrients (Cu, Zn, Mn, Fe) and covered by crosslinked alginate and chitosan. Initially, the process of adsorption of nutrients by zeolite was evaluated and applied to mathematical models to determine the kinetics and isotherm of adsorption. From the zeolite / nutrient powder, tablets were obtained by pressing and covered with polymers using dipping technique. Through the kinetics process, it was possible to conclude that K fits the first-order equation, that is, it is adsorbed on the zeolite by physisorption. The micronutrients are adsorbed to the zeolite by chemisorption. Through the difference between the adsorption capacity of the nutrients and the concentration, it was determined that the Langmuir’s isotherm was most suitable for the nutrient ions evaluated implying that the nutrients are linked by monolayer. The Freundlich isotherm, in which nutrients tend to organize themselves in multilayers under the zeolite, was the one most suitable for Fe. Preliminary data on the release of tablets in water show that the coating prolongs the release of nutrients. Within this context, it was found that this theme is very promising to be worked on in the classroom, as there are a variety of themes (contamination of effluents, water, fertilizers, food, plant growth, etc.) that can be worked in an interdisciplinary way, with this, two learning proposals were developed addressing these topics. We can conclude that the work has the potential to contribute to a better use of nutrients by plants and the reduction of environmental impacts, in addition to promoting an important approach on sustainability for teaching

In Brazil, earth retaining structures have been frequently used as a resource to improve urban areas utilization. The increase of urbanization and demographic index demands, as a side effect, the use of underground parking fields, tunnels, and new urban roads. To extend urban space and provide security against soil collapses, studies in geotechnical engineering are crucial and need to be constantly improved. Due to the diversity of geological contexts, careful and detailed analyses must choose the most appropriate earth retaining structure. In this sense, this work has studied and discussed two types of earth retaining systems that are the most applied by civil engineering in urban roads: soil-nailed and anchored walls. We review the literature regarding the two systems and the main calculation methods for slope stability analysis. Particularly, it was studied slope stability cases of two cut walls implemented in an avenue expansion project at Salvador city, state of Bahia. The analysis of the results indicated that the mixed use of soil-nailed and anchored wall for slope stability of a cut wall was the most coherent solution in terms of technical and economic feasibility.

Information theory studies how communication systems integrate, encode, compute, and transmit information. The neural system is an example where communication takes place with neurons responding to stimuli and conducting electrical impulses by means of action potentials thereby causing a flow of neuronal information throughout the system. In this sense, one of the goals of this work is to study some information theory measures, with special attention to their application in the study of neural connectivity. The second goal is to understand the process of mathematical modeling of neuronal spike-trains prescribed from stochastic chains with memory of variable length as well as proposing estimators for the information metrics based on samples of these chains. Lastly, we study the performance of the estimators via computational simulation.

The training of teachers for the exercise of teaching in Basic Education has been extensively researched and discussed in several contexts. In contrast, the research on teaching training for Higher Education context, especially on the formative trajectory and the performance of professionals, is scarce. In the Higher Education context, research about teacher educators, especially on their professional teaching identity, are rare, whether in the fields of Teacher Education, Education, Science Education, or Chemistry Teaching. Considering the importance of teacher educators, I aim to identify and understand the construction of the professional teaching identity of teacher educators of the undergraduate Chemistry course offered at the Araras campus of the Federal University of São Carlos (UFSCar). In this sense, I sought to answer the question: how does the process of construction of the professional teaching identity of the teacher educators working in an undergraduate course in Chemistry occur? The qualitative research approach dialogued and was supported by the adopted theoretical foundations regarding the training of chemistry teachers, professional and social identity, especially Dubar (2020), of teacher educators such as Vaillant (2003), and in theoretical and methodological assumptions of narrative research, especially Clandinin and Connelly (2015). The methodological steps included a mapping of the teachers working at the Center of Agricultural Sciences (CCA) of UFSCar Araras who worked and/or work in the Chemistry undergraduate course from 2009 to 2019, followed by a semi-structured interview, conducted in the relying upon the mentioned references, among others. I interviewed twelve teacher educators who agreed to participate in the research. I analyzed the interviews contrasting it with the analytical categories of identity proposed by Dubar (2020) through Discourse Analysis. I arranged the narratives into three main axes and their unfolding’s: i) characterization, which presents a personal and professional profile of the teacher trainers; ii) trajectories, which presents elements of personal and professional trajectory; iii) performance, which presents the processes of socialization at the university, the conceptions of the teacher trainers and the actions they develop at the university and in the training of future teachers of chemistry. The results point out that the professional teaching identity of teacher educators is constructed through relational and biographical processes and influenced by the various spaces, places, experiences, and relationships experienced by the teacher educators throughout their trajectories, and also allows us to think about the characteristic axes for thinking about the professional teaching identity of the teacher educators of chemistry teachers with centrality in learning, in its multiple dimensions.

This work evaluated the influence of surface finish resulting from milling on the corrosion resistance of SAE 1020 steel parts in biodiesel (B100) and its blends with petroleum diesel (B15 and B30), through tests of total immersion, crevice corrosion and vapor phase for 2400h at room temperature. For milling, three tool displacement configurations were used, and three parts regions had their surfaces characterized by skewness (Ssk), kurtosis (Sku) and reduced valley depth (Svk) parameters. The statistical analysis of these parameters showed that the three machining configurations produced surfaces with differences related to the predominance of peaks and valleys, with the peaks of the first configuration being steeper than those of the first configuration, suggesting that the tool displacement strategy could present a correlation with the susceptibility to corrosion of the parts. After the tests, it was found that the blends B15, B30, biodiesel (B100) and the total immersion, crevice corrosion and vapor phase tests did not produce significant variations in the roughness parameters. However, taking into account only the machining configuration factor, after 2400h the samples of the first configuration showed significant differences in the mean values of Ssk and Sku, indicating that their surfaces had a greater number of valleys than at 0h and suggesting that the peaks of this configuration were responsible for a larger area of exposure to biodiesel and its blends. Although the surfaces of the other configurations presented some changes resulting from the corrosive action of the diesel/biodiesel blends and biodiesel, for these, no significant changes in the roughness parameters were observed. The formation of passive film on the surfaces and the high electrical resistivity of the studied blends (B15 and B30) and biodiesel (B100) may have influenced the results obtained in the immersion tests, thus suggesting the need for a longer time for these regions the parts had more expressive effects resulting from corrosion.

The innovative process is uncertain and complex. Thus, knowledge becomes a relevant input for innovate activities. In addition to formal knowledge, it is important for innovation, stand out the tacit form, that acquired over time and that it not easily shared by formal process. In this context, assuming that people are the major carriers of tacit knowledge, the mobility of workers is essential to enable exchanges, thus possibility opportunities for knowledge transfers that impact on innovation. The present study aims are to analyze the mobility of skilled workers in Brazilian innovative companies in two specific trienniums and measure the influence of the mobility of skilled workers on innovation. Skilled workers were classified as employees with higher education or in occupations potentially linked to the areas of science and technology (POTEC). Initially, a descriptive analysis about the profile of companies considered to be innovate and of their employees was carried out between the years 2006 and 2011. After that, measure the skilled mobility workers was construed at the firm level in the sectors of extractive industry, transformation industry and electricity and gas. The GLM model with Poisson and Binomial Negative distribution and the TOBIT model were estimated. In the estimations, patent applications by company (dependent variable) were used as an innovation proxy. Skilled mobility of workers between companies was the independent interest variable. The results showed that the mobility of skilled workers is significant and positively impacts in innovation of companies. This result corroborates the importance of knowledge in innovative activities, seeing when moving, the worker increases the possibilities of knowledge exchange via face-to-face contact, in addition to generating new opportunities for access to different contact networks. Furthermore, it was found that the impact of mobility on innovation by POTEC workers is greater than that of workers with higher education.

This research focuses on the study of the transition from early childhood education to elementary education and to support this study, we worked with authors from the history of childhood and the history of education on the concept of childhood and children since the Middle Ages, both in the Europe as in Brazil, until today and, as these concepts are also treated in the official documents of Brazilian education. In addition, the authors of historical cultural psychology contributed to an elucidation of the child's learning and development process. Such research intends to answer the following questions: What happens in relation to playfulness when the child enters the first year of elementary school? Is there a difference between playing in the last year of Early Childhood Education and playing in the first year of Elementary School, based on testimonies of children's narratives? Given this, this research aims to know, examine and understand through children's narratives, the transition process from early childhood education to elementary education with regard to playfulness in the school environment. To achieve this goal, the field research methodology was qualitative, using semi-structured interviews with 13 children, who participated in the collection process in two stages, the first in the last year of early childhood education and the second in the first year of teaching. fundamental. From interviews conducted, from the perspective of oral narratives and based on the content analysis of Bardin (1979), 4 categories were formulated a posteriori. The first category called "Physical Education" presents and discusses registration units about the physical education classes that appeared in children's narratives, the second category, called "Playful Culture", organizes the results of the registration units: playing with water and / or pool, games with fantasy, games of catch, hide and seek and with sand and also the so-called “wooden toy”. The third was called “Curricular Components” and addresses the registration units for teaching and learning activities carried out by children, using the “activity” registration unit and, finally, the last category entitled “Differences between early childhood education” and elementary education ”brings the registration units that reflect the differences between the stages of basic education according to the children's narratives, being these registration units: recreation; computer classes; playground, and some other registration units, mentioned only once, but which bring important messages to answer the questions of this research. Finally, in the final considerations, the contributions of this study to the school education of children and their possible consequences are treated.

During the covid-19 pandemic, many sectors of civil society were harmed in all different ways. The school was one of the institutions that felt intensely the impacts of this phenomenon, starting by its closure, which opened up, in a way never seen before, the inequalities of our educational system. With regard to the pedagogical scope, even though it is still not clear what the real impacts of all this time without face-to-face activities at school are, it is important to think about what strategies are being successfully applied by teachers, considering that understanding this scenario is a way of listing new teaching practices that can be adopted in remote education. With this in mind, this work seeks to understand how school physical education rethought the teaching of the thematic unit 'fights in the world', taking into account that this content supposedly requires direct contact between the participants in order to be learned. Considering that the main goal of this research was to analyze a didactic unit for teaching fights, built in a collaborative way, with the Physical Education teacher from the state school system in the state of São Paulo. In order to carry it out qualitatively, I chose as data collection instruments a semi-structured interview with a teacher at the school, a questionnaire sent to the students in a ninth grade class, and finally, comments on a classroom's facebook group, created by the school's coordination. Data were analyzed, reaching the following categories. a) Being a teacher in the pandemic, encompassing my reflections on the understanding that the interviewed teacher has about this process; b) Planning of physical education classes during the pandemic, in which I was able to point out how the curriculum influenced the organization of the teaching unit during this pandemic moment; and, c) If the fights arouse interest, whoever fights does not fight either, in which I evidenced the students' understanding of the didactic unit worked on. As final considerations, I could infer that being a teacher in the pandemic is not a simple task, requiring an apparently more urgent effort to reflect on pedagogical practice. In addition, the fact that the Currículo Paulista was designed for face-to-face teaching and had been applied online was an imperative for the way we conduct the class planning. Finally, I understood that the students had good use of the didactic unit, considering the rather elaborate understanding of the 'world struggles' they had, in addition to the autonomy they had to build their own meanings in relation to the theme, which was expressed, respectively, on the Facebook rating and comments.

During 2019, in Belo Horizonte (MG), a total of 456 men who committed violence, punished by the Law 11.340 (Maria da Penha Law), were referred by the justice system to serve part of their alternative sentence in existing reflection groups in two programs in the city: Albam Institute and Dialogar Program of Civil Police of Minas Gerais State. There were respondents found by this survey. The data obtained resulted from the application of questionnaires to 30% of the total number of participants in these reflection groups operating in Belo Horizonte that year - meaning the application of 137 questionnaires related to childhood and 137 questionnaires on youth. The main purpose of this research was to carry out an empirical study in Belo Horizonte that would allow to find patterns related to practices based on beliefs and customs, moral values in which men who committed violence against women in intimate relationships were socialized, punished by the Maria da Penha Law. The way to make this proposal viable was to reconstruct the memories of primary and secondary socialization of these men, in view of an approximation with the dimension of the habitus (conf. Bourdieu 1979:164; e Bourdieu, 1980:88 e 89; Bourdieu, 1987:81structured in this trajectory. The tested hypothesis was built from the objective of exploring a little more the notion of an increase in violence associated with a movement to change the patterns of masculinity, in view of the notions brought by Connell and Messersmith (1985 and 2013); Walby (1991), Patman (1998), Bourdieu (1998) and Segato (2006).

Services companies like telephony, health plans, internet and others, have redirect their marketing strategies in the customers retention. By maintaining a business relationship with their consumers, companies guarantee capital collection, reducing spending on finding new users. The study of the occurrence of churn is important for customer retention because, by knowing the profile of these consumers, companies can identify others who may breach the contract. This work aims to predict the probability of occurrence of churn based on the relationship time between customer and company, considering services characteristics and the profile of the consumer, using survival analisys and regression models. The exponential model was used for lifetimes, considering customers divided into different groups, or categories. A frailty term was considered to describe the common risk shared by individuals within the group. With the shared frailty model, it was possible to estimate the probability of churn, at a given time, for the group as a whole, as well as for each of the individuals in the group. The shared frailty model was applied to a database of a phone company, whose analyzes were carried out with two clusters: type of subscription and education level of the customers. With the frailty model estimated for the clusters, it was possible to satisfactorily rank the risk of the groups.

The activity of the cement industry results in a huge amount of CO2 emissions mainly due to the calcination of limestone. In this context, numerous researches have been approaching additions in cementitious composites to replace cement amounts in the production of mortars and concretes. It is worth noting that these additions usually come from waste from other industries, thus, in addition to reducing the amount of discarded materials, it reduces the damage caused by the inappropriate destination of this waste. However, for these replacements to be considered viable, several factors must be analyzed, seeking to know the material and its behavior given the new utility. Studies on the use of finely ground glass as a partial substitute for cement have been developed, mainly due to the verification of its good performance as a pozzolanic material with particles smaller than 300 µm. In addition to this pozzolanicity, a physical filling action by the fine grains of the material (filler effect) has been observed, which results in the improvement of the modified cementitious composite. But few studies are deepening the individual contribution of glass powder in cementitious composites due to its physical and chemical effects. Thus, this research aimed to quantify the development of mechanical properties of mortars caused by filling and the pozzolanic effect of the glass powder separately. For this, initially sought to characterize the glass powder and determine its pozzolanic activity and compare the results with those found in the literature for other additions and technical standards. Mortars were developed with different levels of volumetric replacement (0%, 10%, 20%, 30%, and 50%) of cement by finely ground glass passing through the mesh #200 (75 µm), seeking to evaluate the incorporation of glass powder in the physical and mechanical properties of mortars. To differentiate the filler effect from the pozzolanic one, limestone filler was used, whose particle size distribution is similar to the studied glass powder. Mortar characterization tests were carried out on the properties of axial compressive strength, water absorption by capillary, tensile strength by diametrical compression, and static modulus of elasticity for mortars with cement contents replaced by glass and limestone filler in the same amount. The results of the pozzolanic activity of the glass powder indicated reactivity by the Modified Chapelle and electrical conductivity tests, in addition to the chemical composition with the sum of SiO2, Al2O3, and Fe2O3 oxides greater than 70%, and amorphous predominance by XRD. The mechanical results obtained were favorable to the cement replacement content by glass powder in 20% and it was possible to verify that in all the analyzed properties there was the presence of the two effects (filler and pozzolanic) of the finely ground glass in the mortars. The slower chemical activity of the glass powder was observed in relation to cement, with 24% gain in compressive strength due to pozzolanic effect concerning the reference value at the most advanced age of the study (91 days).

The following thesis identifies and analyzes the determinants of the adoption and the intensity of adoption of precision agriculture technologies (PATs) by sugarcane suppliers in the state of São Paulo, Brazil, as well as the main barriers to adoption. In person interviews with 131 sugarcane farmers provided cross-sectional farm level data from the 2018/19 crop year. The farmers were interviewed using a semi-structured questionnaire and the primary data were analyzed by means of descriptive statistics, hypothesis test and count data models. Six PATs adopted by the farmers were identified: GNSS and images for rows planning; tractor/harvester with automatic guidance system; georeferenced grids for soil sampling; images (satellite and/or ARP) for mapping pest and yield; variable rate application of fertilizers; and variable rate application of pesticide. The adoption and adoption intensity (dependent variable) were measured as the number of PATs used by farmers. Fifty-three farmers adopted at least one of these technologies, while 78 farmers did not. The results show that the agricultural information provided by the sugarcane mill, the farm size, as well as the perception of increased productivity are factors that positively and significantly influence the farmer’s decision of adoption PATs. The access to technical assistance information, the participation in agricultural events (workshop, farms fair and farm field days), the farmer’s previous experience, the availability of credit and the perception of increased productivity positively impact the decision to adopt a greater number of PATs, that is, the adoption intensity of the PATs. The adopters indicated that they had faced difficulties related to the connectivity in the field, the lack of technical assistance from equipment suppliers, the lack of trained labor and the incompatibility of the communication interface between computer systems of different agricultural equipment as the main barriers to adoption. For the non-adopters, the main barriers for adoption were the high initial investment.

This work presents the basical theorics fundaments of the generalized linear models e the caracteristiscs of the univariate multinomial and binomial logistic regression analysis. Practical aplications of binomial regression and of multinomial were perfomed. The aplication were related the evaluation of effectiveness of an herbicide for the control of a certain weed; of the effectiveness of the radiation level for the house flies control; and for the evaluation of the degree of retinopathy as a function of the individuals' diabetes and other condition. The code of the implementation of the analitycals procedures, run by the softwares R, MATLAB e SAS are avaliable. Also are descrited three bivariate multinomial logistic reggression models: fixed effects conditional, margimal and mixed effects. Applications for each models are presented. The applications are about: the degree of retinopathy avaliation in both eyes of patientsas a function of diabetics and other individual features; the severity of rheumatoid arthritis as a function of the patients status. The code of the implementation of the analitycals procedures, run by the softwares R, MATLAB e SAS are avaliable.
