The present study had the objective of identifying and problematizing the teaching knowledge assumed in some pre-selected sections from the Spanish-language book: Enlaces: Español para Jóvenes Brasileños volume1 (OSMAN, 2013), approved by the Programa Nacional do Livro Didático (PNLD, 2015) and also, observing the guidelines proposed by the Teacher's Guide (TG) in the same work in order to identify and problematize the teaching knowledge as well. As a theoretical basis, a brief reflection was made on the importance of the textbook and the teacher's guide for foreign language teaching, and the evolution and main characteristics of the PNLD were presented. The theoretical basis was based on Tardif (2002, 2005, and 2012) and Gauthier et al (2013). Nevertheless, to carry out the analysis of the textbook, it was only used the studies of Gauthier et al (2013), since it presents more indications of the types of knowledge that are mobilized by the teachers, besides being based on a vision of a pedagogical practice more pragmatic. Then the analysis was based on a descriptive and interpretative view of the teacher knowledge assumed in the analyzed pages and on the knowledge observed through what the teacher's guide prescribes. As a result, the analyses showed the predominance of the "knowledge of pedagogical action" in the guidelines contained in the teacher's guide. It also demonstrated that the recommendations are not sufficient for the concreteness of the specific objectives of the activities neither for the attitudinal proposals listed by the sections of the units defined for analysis, requesting other knowledge for the adequacy of the proposed contents too. In this sense, the recurrence of the knowledge of pedagogical action has indicated that for the good performance of a teaching based on a textbook will depend mainly, on the acuity of the teacher, for having to adapt the book in the attempt to accomplish the disciplinary content and mainly to achieve the attitudinal contents and objectives stipulated by the sections.

This work approaches theoretical topics of physics addressed to high school, which don’t usually appear in the literature of physics teaching but cause questions and curiosity in the students. This work used experimental techniques with everyday instruments. The topics covered were: the Circular Movement for First Year classes; study of Lenses and Vision for the second year, and the Electrical Circuits, series and parallel for the third year. The first and third year classes belong to a public school and the second year class in a private school, both at the city of Campinas. The experiments had the goal of using materials from the students' daily life, allowing a simple and low cost construction through donations and obsolete objects. This work also aims at the easy access to experimentation and to integrate theory to practice of the topics addressed in classes. In this way, it allows the experimentation as a catalyst or a facilitator of the learning, through motivation, the trial and error method, and by approximating the daily educational system to the scholar, in order to lead the student to build a meaningful learning. The data from the Physics teaching extent were collected using the qualitative research through questionnaires and testimonials from the students, which demonstrate the acceptance and the beginning of learning by them. The construction of the educational product takes into account several items: a lesson script, theoretical contributions to be developed and the experiments carried out with the students.

The present research analyzes the proposals on Education in the deliberations of the National Conferences of the Person with Disabilities - 2006, 2008 and 2012. First it discusses the social movements of the person with disability, the social participation theme, the composition of the national council of the rights of the person with disability - CONADE proposes the conferences at the municipal, state, regional and last national level, which have a great impact in the elaboration of public policies for people with disabilities. From there, you will ask how special education is designed for people with disabilities. The theoretical methodological foundation adopted for this work is dialectical historical materialism. We understand that this theoretical methodological paradigm is a set of ideas, values and actions in the search to understand the contradictions between man, society and politics, considered as parts of the totality of reality. The methodology used was documentary analysis in primary sources: minutes of the national conferences held by CONADE for the years 2006, 2008 and 2012, available on the website of the national council, in the form of annals. The analysis of the deliberations in education was made in two axes: Education and Teacher Training; Education and Accessibility. The results that the deliberations contemplated were the demand for curricular and thematic components alluding to people with disabilities from basic, technological and vocational education to higher education, among them, universal design, assistive technologies, linguistic resources and the highlight is for the social movement of the deaf with the proposition of the bilingual school. Even if education in an inclusive perspective is a significant reference in the total of deliberations, among the chosen axes; the difficulties that arise from the implementation of public policies in a country with the size of Brazil are a huge challenge

Since the 1980s, after a series of publications in the academic and business literature, initiatives to implement the Toyotist approach become common in companies located in developed countries and, consequently, in organizations located in Latin America, Asia and Africa, as the headquarters begin to spread their learning to their subsidiaries. Thus, this work aimed to study the multi-plant adoption of a kaizen-based employee involvement program in two branches of an organization, located in Brazil (BR) and China (CH). Among the various programs and techniques associated with Lean Manufacturing, the choice for kaizen was due to the interest in understanding the possible mismatches between the discourses present in the Toyotist literature and the reality of modern companies that call themselves lean. The analysis of the results allowed to understand the main differences between BR and CH programs, with emphasis on the level of employee participation, the use of group ideas, the rewards system and the gains obtained. It should be noted that in BR the level of employee adherence to the program has been greater and this fact can be explained in part by its alignment with critical managerial practices to the establishment of the environment and model conducive to the culture of continuous improvement. However, the research found that the organization has failed in 9 of the 18 practices evaluated for BR and in 13 of the 18 practices evaluated for CH. That is, although the Toyotist literature presents kaizen programs as a form of partnership, collaboration and sharing between employee and employer, this becomes subject oof questions in the context studied.

The responding by exclusion is defined as the immediate choice of an unknown comparison stimulus (figure or object) in front of a model stimulus also unknown. For Behavior Analysis, it is one of the processes by which children learn to relate new words to new objects or qualities, aiding in vocabulary acquisition research. Thus, for populations at risk for language development, such as babies born preterm and underweight, analyzes of the response by exclusion can serve as a basis for formulating proposals for rapid learning of new words. Such a process has been extensively investigated on an experimental basis and is based on studies generally carried out by teaching "conditional discriminations" with the model pairing technique (MTS). The arms of this study were to attest to the occurrence of the exclusion response in preterm and low birth weight infants with ages between 18 and 21 months; To verify the learning of object-object relations after a single exclusion probe and to verify the maintenance of the emergent relation (name-object) seven days after the exclusion probe. Participants were selected through contact with those responsible, as soon as the initial repertoire of the babies' overall development was surveyed. The general procedure employed three phases with the following sequence: Phase 1) selection response teaching; Teaching of auditory-visual conditional relations in baselines using defined stimuli; Probes of exclusion and learning without mask; Phase 2) teaching response to the mask; Teaching of auditory-visual conditional relations in baselines with defined stimuli with mask; Probes of exclusion, control and learning with mask; Phase 3) reexposure to the teaching of auditory-visual conditional relations in baselines with defined mask stimuli; exclusion, control and learning probes with mask and verification probe maintenance of the emergent relation (name-object), after seven days of performing the exclusion probe. The performance of each participant was analyzed according to the programmed controls for the establishment of conditional discrimination in both the teaching stages and the various probes used. All participants responded by exclusion in the procedure without mask and in sessions with mask only one participant did not respond by exclusion for an indefinite object-object relationship; The control and learning probes showed variety in the results. The overall results suggest that infants with preterm and low birth conditions responding by exclusion and that some participants in the emergence relationship verification probe showed learning for one of the name-object relationships.

Considering the importance of teaching appropriate behavioral repertoires for children with Autism Spectrum Disorder (ASD) in a wide variety of environments in which the child is inserted and the need for appropriate intervention for the school inclusion of this Special Education Target Audience (SETA) and the potential of the Collaborative Teaching, this study aimed to verify the effects of individualized teaching in establishing appropriate behavior in the classroom for children with ASD. Initiating collecting the complaints about the students's inadequate behavior and afterwards an elaboration of a program that aimed to modify the teaching techniques applied to the researcher and also the classroom teachers in a Collaborative Teaching way. The participants of this research were two children with ASD regularly enrolled in the first year of elementary school. The research was qualitative, in a collaborative type. The data collection procedure occurred in two stages. The first stage was the contact with the school staff to gather the demands/complaints for the future participating students and observation of the participants in their classroom in order to record the appropriate and inappropriate behaviors they emitted. In the second stage, an individual intervention plan was drafted by the researcher according to the concepts of Applied Behavior Analysis (ABA). The results show that both participants acquired new and adequate behavioral repertoires, decreased inappropriate behaviors in relation to stage 1 of this procedure and improved behaviors already learned The collaboration between the classroom teacher and the researcher developed well and according with what was expected in all the collaboration stages, it's possible that if the research project was longer the collaborative teaching would achieve all the collaboration criteria. It is concluded that the Applied Behavior Analysis (ABA) in school context offers a quality intervention for a quality intervention for this SETA. It is concluded that the Applied Behavior Analysis (ABA) in school context offers a quality intervention for this SETA.

Kinetic studies related to microwave assisted sintering of ceramic materials are scarce in the literature, as well as on a nanoscale and submicron scale. Therefore, the aim of this dissertation was to study microwave assisted sintering using an isothermal grain growth method for materials with different dielectric properties. The chosen materials (ZnO, Fe2O3 and TiO2) have technological and industrial importance and include a wide range of applications. The nanometric powders were synthesized by the sol-gel method and the submicron powders were purchased commercially. Initially, all powders were conformed and analyzed by conventional dilatometry at different heating rates, obtaining values of activation energy of the initial stage of sintering, using non-isothermal methods. After this study, the same powders were microwave sintered at different heating rates, and the study of sintering kinetics was carried out using an isothermal grain growth method, allowing the calculation of activation energy of grain growth. The results were compared for each material, in relation to the nano and submicron scales, the heating rate effect and the type of heating. The results obtained from microwave assisted sintering showed a tendency to decrease the final grain size with the increase of the heating rate. Moreover, for the submicron systems, the tendency was lower values of activation energy of grain growth, showing that the energy provided in the submicron systems favored densification. It was also observed that in materials with good dielectric properties, rapid densification occurred at temperatures lower than those observed in conventional heating, and in the case of ZnO, high diffusion coefficients helped densification. In the case of TiO2, the densification was affected, corroborating to be a poor absorber to microwave radiation.

Machine learning techniques have been actively pursued in the last years, mainly due to the great number of applications that make use of some sort of intelligent mechanism for decision-making processes. In this context, among the several studies on classification techniques and how to improve them, the ensemble of classifiers has achieved considerable evidence in the literature. In this circumstance, a classifier with significant growth is the technique called Optimum-Path Forest (OPF), which is considerable ease to manipulate, has no parameters in some versions, and it is efficient in the training phase. Since OPF is a relatively new technique in the literature, and we have few studies on ensemble of OPF classifiers only, this work aims to provide a more detailed study in ensemble techniques regarding the OPF classifier. This work has proposed an improved version of OPF, which learns a score-based confidence level for each training sample in order to turn the classification process “smarter” (i.e., more reliable), which is further used in a combination process with majority voting. Furthermore, we also proposed the combination of classifiers using an ensemble pruning strategy driven by meta-heuristics based on quaternions. In addition, we proposed an extension of the ensemble pruning using OPF classifiers in the context of remote sensing images. Finally, the probabilistic OPF was proposed, since the OPF presents only abstract outputs. Experimental results over synthetic and real datasets showed the effectiveness and efficiency of the proposed approaches for classification problems.

In this study an aqueous dispersion of a polyethylene copolymer with a content of 6 wt% of acrylic acid was used as an alternative medium for incorporation of cellulosic fibers (FC), nanofibrils (NFC) and lignocellulosic nanofibrils with 3 wt% of lignin (LCNF) from Eucalyptus grandis to compare the effect of size and composition on the properties of films obtained by casting and pressing. The amount of the fibers varied from 0 to 30%wt. The appearance, optical, thermal and mechanical properties as well as the film morphology were evaluated for comparison of fiber size and composition. The films are transparent up to 10%wt of FC and NFC, indicating good dispersion of the fibers, being brownish in the presence of NFLC. The addition of FC and NFC promoted improvements up to 900% in the Young modulus of the films. NFLC containing films showed superior Young modulus and tensile strength around 1700% and 35% higher than PE samples. Scanning electron microscopy (SEM) morphology of the films showed a good dispersion, but a poor distribution of the fibers through the matrix, with PE-rich and fiber-rich regions for the cast-processed composites and nanocomposites. In this way, the properties of NFC films were also evaluated after a extrusion step using two different screw rotations. SEM morphology of the extruded films revealed the occurrence of re-agglomeration and a consequent decrease on the aspect ratio of NFC into the PE matrix, with significant reduction of the Young's modulus and transparency. In addition, the polyolefin aqueous dispersions processed by casting seem to be a promising and relatively fast route for obtaining polyolefin/cellulose nanocomposites films, but the interconnected web like morphology of NFC must be preserved for obtaining better mechanical properties.

The construction industry did not follow the others industries as regards developments of the labor resources and presents low levels productivity. The labor productivity is mainly responsible for the rhythm of work, therefore, know the productivity of a task is of extreme importance and in possession of this information, if reliable, various benefits can be achieved. Specifically, in the execution of the building systems, this information is very scarce due to the difficulties of data collection of fragmented services, added to the frequent outsourcings adopted by builders companies. This work aims to deepen the knowledge on labor productivity of execution of Sanitary and Plumbing Building Systems when these efforts are applied with management systems involving kits or materials and techniques not measured yet. Among the results obtained are the measurement of the labor of productivity of the Sanitary and Plumbing Building Systems executed with Polypropylene Random Copolymer, the comparative analysis of this with other materials available in the market with the same destination of use, and the advances on the productivity advantages of the pre-production and subsequent installation of hydraulic kits that, if in ideal situations of context reached productivity 3.5 times greater than labor productivity of the conventional system, in the most unfavorable scenarios obtained timid gains of productivity, demonstrated as a whole an expressive gain of efficiency. In this way, the main contribution of this work consist in the possibilities the data collected allow in the field of decision making concerning the constructive method of Sanitary and Plumbing Building Systems with Polypropylene Random Copolymer and encourage the adoption of models that involve rationalized production.

This research intends to explore the filmmaking activities of Torquato Neto in the beginning of the 70´s. Throughout his artistic life course, Torquato crossed diferent sorts of media, producing and stimulating Brazilian independent culture. During the last three years of his life, he accomplished what we call turn to cinema, the period we´ll analyze in this dissertation. We'll start analyzing the relation between the movies Nosferato no Brasil (Ivan Cardoso, 1971), Helô e Dirce (Luiz Otávio Pimentel, 1972), Terror na Vermelha (Torquato Neto, 1972) and the writings from the Geléia Geral column in the newspaper Última Hora, published between august 1971 and march 1972. Besides the relation between this works, Torquato Neto´s actions as a booster agent for the super-8 production throughout the 70´s will be discussed.

Through the development of the history of literary texts inscription, it is possible to observe that, in the Western world, from the predominance of literate culture, the book has been characterized as the main mean of literary circulation. This appropriation stablished itself in a deep way, once the book was consolidate, increasingly, as the formalization of the detention of literaty and subjective expression. (CHARTIER, 2007). In this sense, from the moment when these literary productions begin to manifest in other means in the contemporary scenario of digital creations, there are reactions of estrangement and devaluation of new productions, precisely because they are configured in different materiality (ROCHA, 2014a). Regarding these considerations, we delimit as the corpus of this dissertation the texts of the Brazilian author Ismael Caneppele. Our research proposes a reading of the novel Os famosos e os duendes da morte (2010) and the blog Ismael Pele de Cão (2011-2014), considering the different material formalizations that each one of these texts present. We observed which characteristics of the text in printed book and which specifities of the text from the blog, on the internet. In our analysis, we assumed the inextricable relation between the text and the materiality, performing the necessary mediations in the critical work development. With the propose of developing such propositions, we observed that one of the central points of the issue is based on comprehension of the specificities of different media aproached, once each one stablish a different own way in relation to others. Therefore, we based the studies here presented on the theory of remediation, proposed by Bolter and Grusin (1999), that problematizes the articulation between the different media, as it postulates that the new media do not overcome or replace the previous, but coexist, which reconfigures their meaning. Along with remediation, with the objective of seizing the intertextual movements proposed on the texts, we use the concept of cultural recycling (KLUSCINSKAS; MOSER, 2007), whose constitution is based on a review of the aesthetical concept from reconsidering the paradigma “novelty, originality, authenticity”, that in the current context supports itself in the triad “copy, recycling and seriation”. From this analysis, we developed the notion of movement and we were able to conclude that it works as a technique of writing, assuming the fundamental role in the comprehension of the intrinsic relation between the texts and the materialities in the productions of Ismael Caneppele, as a way to evidence particularities of the author’s literary project. Furthermore, in a broader sense, our observations help us to understand some aspects of contemporary literature, of the literary categories historically stablished, as in the case of the author, reader and work, whose values were cristalized in contexts culturally different, that we discuss and evaluate through the works of Ismael Caneppele.

The genus Citrus contains a wide variety of fruit-producing species such as oranges, lemons, limes and mandarins that are highly popular in the world. Brazil is one of the main citrus producers, currently leading the world production of oranges. The Brazilian citrus industry is extremely important because of it is great activity that generates jobs, thus contributing to the socioeconomic development of the country. However, the genetic background used in the Brazilian citriculture is still very narrow, with few varieties being cultivated commercially. This is a reflection of the fact that there is still a great difficulty in obtaining superior individuals through traditional breeding due to the limitations presented by the citrus crop. This makes it necessary to develop new technologies, especially those that exploit the already sequenced genomes. One of these technologies is the genome editing, where it is possible to make disruptions in specific points in the genome of a given organism, leading to mutations or substitutions of DNA fragments. Among the various techniques used for genome editing, CRISPR / CAS9 is the most promising because of its ease of use. With its first studies in 2013, there is an increasing number of papers showing CRISPR / CAS9 mediated genome editing in different organisms, including plants. At the present time, for citrus there are works of two groups in which this technology was used to generate mutant plants. Therefore, the application of this technology could be better exploited to take citrus studies in Brazil to another level, with prospects of generation of new varieties. Thus, this project had a central objective to optimize systems for generation of mutants via CRISPR / CAS9 in citrus. In order to explore the existing methodologies for genome editing in plants, constructs of vectors with targets in genes of interest for the study of disease resistance were made using vectors available in the literature. From this initial work, it was possible to propose two improvements for optimization of the process: the use of transient transformation to identify mutations and consequent efficiency of the CRISPR vector and the construction of a new vector for plant genome editing. We were able to evaluate some parameters and to optimize the methodology of transient transformation in sweet orange, resulting in an average of up to 93% of transformed leaf discs. It was also possible to conclude the construction of a new vector for plant genome editing that has the advantages of having reduced size, easy customization in the vector itself and resistance to kanamycin in plants and bacteria. The advances obtained in this work can be applied in studies of several areas not only of citrus, but also of other cultures.

This assignment has the goals to analyze the literacy condition of youth and adults, enrolled in the special school for intellectual disability and propose a reflexion about the educational purpose of the special school. The theoretical methodology basis looks at the Historical and Critical Pedagogy and its fundamentals. It has been investigated the literacy by ways of writing samples, produced from a list of words dictated by the researcher, the writing of their name and by oral questions about their knowledge of personal data, such as their full name and date of birth. The investigation was produced with students of two special schools, from a municipality located in the interior of the São Paulo state. The results show that the students enrolled for more than five years didn’t appropriate themselves of the system of alphabetical writing, necessary knowledge for learning and academical and social development. They also review that the special school doesn’t have a pedagogical planning that act in the promotion of knowledge and that demonstrate possibilities of advancement of those students. The research looks into offering elements for the analysis of a reality ruled in a model of philanthropic special education, in which will result in the school and social exclusion of private subjects of knowledge appropriation.

The professionalizing technical education deals with the challenge of training professionals for new professions, which entails the shaping of technical courses that have a demand for teachers with specific experiences. The Mechanics Technical Course on Aircraft Maintenance is an example of these cases. In the present study, an Instructional Material (IM) was developed, and its usage focused on teachers and students that were interested in the concepts of Circular Motion, Torque, Inertia Momentum, Angular Momentum, Gyroscopic Precession and Energy Conservation of the angular movement, based on David Ausubel’s theoretical reference. Such matters should have an approach in the course of these upcoming professionals, highlighting the need of promoting examples, exercises and practical activities of relevance and which represent the training demand of these students. The IM application took place in a professionalizing Technical Course of Instituto Federal de São Paulo (IFSP), São Carlos campus, where the researcher is also a teacher. The class is composed of second or third year students from high school that, at a different time, attend the complementary Professionalizing School. The assignment developed with the IM showed signs of good feedback along with the students, considering that the exercises held in the post-test reveal a significant increase of right answers.

The Centro APTA Citros Sylvio Moreira/IAC has been conducting an extensive breeding program of citrus via directed crosses. In a previous study with Citrushuanglongbing pathosystem (HLB) held in our group, using a population obtained by hybridization between Citrus sunki and Poncirus trifoliata, differences were found in the multiplication of the bacterium Candidatus Liberibacter asiaticus (CLas), the causal agent of HLB, in the parents and in the progeny. It was observed that the rate of infection and bacterial concentration was higher in C. sunki than in P. trifoliata. Thus, it is important to deepen the studies with this genus and hybrids to increase knowledge of which mechanisms could be involved in the tolerance to HLB, considered the most important disease of citrus currently. In this sense, the objective of this study was to establish sinteny between the linkage groups of the C. sunki and P. trifoliata maps with the genome of Citrus sinensis and to map genomic regions associated to tolerance CLas bacterium through phenotypic analysis (QTLs) and gene expression (eQTLs). With the comparative analysis between maps and genome, it was observed that all the linkage groups showed synteny with reference genome chromosomes used, with the exception of the linkage group 10 of the C. sunki map. For the phenotypic data, a population of 79 F1 hybrids between C. sunki and P. trifoliata was used. The quantification of the bacterium and accumulation of starch in the leaves were evaluated after two years of inoculation with the pathogen. Through the statistical analysis of the mixed model it was possible to group the hybrids into resistant, tolerant and susceptible, being important the validation of these data in the field. The expression of 14 candidate genes related to HLB was performed in 72 hybrids of the population and used as expression data for the mapping of eQTLs. It was possible to locate nine QTLs and 52 eQTLs on the C. sunki genitor map and 17 QTLs and 40 eQTLs were found on the P. trifoliata genitor map. The overlapping eQTLs of the majority genes of QTL (phenotypic data) indicates that the genes are related to the phenotype and are probably responsive to the pathogen infection.

In this essay we will briefly study the concept of Algebra. We will introduce a little of Group Representation Theory, looking specifically at Young's Theory, which allows us to present explicitly the decomposition of the group algebra FSn into simple subalgebras, where Sn is the symmetric group of order n!. We will also talk about Polynomial Identities and Graded Polynomial Identities, and some pertinent PI-Theory's results. We will relate Symmetrical Groups Representation Theories with PI-Theory. We will show all the Z2-graded polynomial identities for the algebras M2(F) and M1,1(E), where E is the Grassmann Algebra infinitely generated over a field F of characteristic zero. Finally, we will present all G-gradings possibilities for the algebra UT2(F), of the upper triangular matrices of order two with entries in a field of characteristic zero (we will see that, up to isomorphisms, there are only two possibilities), moreover, we will find all the G-graded polynomial identities for this algebra and we will show a numerical sequence involving the graded cocaracteres.

We consider the approximations @tu + @xf(u) + b1@3xu + b2@t@2xu + 2c@t@4 xu = @2xu (4) and @tu + @xf(u) + @2xu + 2b@3 xu + 3c@4xu + 5d@5xu = @2xu (5) of the Rosenau-KdV-RLW and Benney-Lin equations and supplementing them with an initial condition u(0; x) = u ; ;0(x) (6) we establish the global existence of solutions u ; for the problems (4){(6) and (5){(6). Moreover, we study the limiting behaviour of the sequence u ; when the parameters and are kept in balance and tend to zero, and we prove that the limit function consists of the unique entropy solution of the conservation law @tu + @xf(u) = 0: The tools used will be the Compensated Compactness Theory developed by Tartar-Murat [22, 23, 27, 28] and DiPerna's theory [10, 11] on Entropy Measure-Valued Solutions together with a number of uniform estimates on the sequence u ; obtained during the text.

Services are not only important for companies in the tertiary sector, but also for manufacturing companies. With the servitization strategy, these companies are offering more services added to their products and developing new service offerings in which the product is no longer the focus on the offer to the customer. The servitization, understood as this process for service-centric business models, requires new postures, processes, capabilities, and resources. Among the processes, manufacturing companies need to start developing not just products, but services as well. With this, the New Service Development (NSD) gains importance for manufacturing companies. In spite of this importance, there is no consensus in the literature about NSD structuring and its integration with the product development process (PDP) in manufacturing companies. Thus, this dissertation sought to focus on the following research questions: How do manufacturing companies organize their New Service Development processes, and how is this process integrated into the New Product Development process? Therefore, the objective is to characterize and analyze the process of New Service Development in the context of manufacturing companies. To achieve this objective, two research strategies were used: Systematic Bibliographic Review and the Multiple Case Study in two manufacturing companies of truck manufacturers. Through semi-structured interviews, the heads of the areas involved with the NSD were interviewed in order to identify information regarding the structuring of the NSD. The results indicate that most of the innovations made by the companies investigated refer to innovations of the ad hoc type and consist in the development of new solutions to the problem of a client. It was also observed that the companies do not have an area dedicated to the NSD, and this responsibility falls on the After Sales area due to the approach with the clients. It is also concluded that the companies do not perform all the steps provided in the traditional models and have low levels of NSD formalization. Finally, on the integration of PDP and NSD processes, there is a positive consensus among companies, but this is understood as the exchange of information. In this way, the results indicate that the processes are performed in a non-integrated way.
