    Physalaemus is the largest genus, with regard to number of species, of the subfamily Leiuperinae, the taxonomy of which has been the subject of recent studies due to the high intraspecific and low interspecific variation within the group, with patterns of variation possibly related to geographic distribution. The Physalaemus albifrons species was first collected by Johann Baptiste von Spix in 1824, and its type locality is the "Province of Bahia", even though it is distributed from Maranhão to Minas Gerais, in regions characterized by the Caatinga morphoclimatic zone in areas of transition with the Cerrado. Due to the variation in the dorsal pattern found in Physalaemus albifrons, authors have put foward the hypothesis of the species being included in a species complex, meaning there would be more species registered under a single common name. Based on this, 98 individuals were studied, associated with each sampled location by means of analysis of morphological and morphometric characters, thus redescribing the species. Physalaemus albifrons presents four intrapopulational dorsal coloration patterns, varying from homogeneously spotless; longitudinal and irregular linear dark spots; as well as dark spots in an omega-like pattern. The second tubercle next to the tibiotarsal articulation, the absence of inguinal glands and the snout-vent length from 18,1 mm to 33,8mm proved to be diagnostic features in order to differentiate Physalaemus.albifrons from other species of the genus. This species, which may also be described as being average-sized for this genus, with the head greater in width than in length; and the snout subelliptical in dorsal view. The populations presents morphological variation as to the distinction of the tympanic ring which might be visible in some individuals and indistinguishable in others, leading to the definition of two morphological groups which are unified through canonical discriminant analysis, therefore discarding the possible characterization of the species complex in Physalaemus albifrons.

    The integrated network management system aims to manage the telecommunications network, regardless of network elements technology in order to identify the causes of problems, providing a more assertive decision making to remedy these problems and make the network available and operational. Thus, can to cater to the market that is increasingly demanding with the level of quality telecommunications products and services. Given this need, integrated networks management system belongs to a real company needs to respond quickly to customers' expectations with respect to requests for new functions system, and perform technology upgrades periodically. However, the integrated network management system development use centered-source technologies, and it requires great effort and hinders reuse. In this context, this master's project presents a proposal to facilitate the integrated network management system development using the techniques of MDD (Model Driven Development). MDD emphasizes the use of models in software development. These models specify the rules of business domain at a high level of abstraction, i.e., regardless of the programming language and to run the software platform. With appropriate computational tools transformations of models in the source code are performed. The use of MDD can provide software reuse procedurally, enabling faster development, lower cost, produce a flexible software and enable faster modifications. To apply MDD approach, a Domain Specific Language (DSL) for the configuration management of integrated network management system setting is designed to facilitate the inclusion of a new technology to be managed by the system, while providing faster development and with fewer errors of code. To evaluate the proposal, an experiment was conducted with the participation of software developers that know the system and work in this real company. The results showed that according to the descriptive analyses there was a reduction in the time spent in application development when it was used DSL compared to the specialization of classes. However, hypotheses tests showed no such reduction. The insertion of errors in the code occurred only in applications developed using specialization classes. The use of DSL provided a broader view of the business rule and you do not need knowledge of the programming language, once the code was automatically generated.

    In the São Paulo State predominated two large phytoecological formations: the semideciduous forests and the savanna. The extensive use of these areas mainly for cane sugar plantations and other monocultures, caused a high loss of habitats. While still play an important role in maintaining the biodiversity of the State, there is a lack of information on bird communities in this region. In this sense, we have developed a comprehensive study on the avifauna of Porto Ferreira State Park (PFSP), which protects one of the few stretches of ecological tension between semideciduous forest and savanna in São Paulo. In Chapter I, we analyze the composition and structure of PFSP‟s bird community. We recorded 207 bird species in the area, between February 2011 and October 2013, including 15 threatened/near threatened species, 22 endemic to the Atlantic Forest and two endemic to savanna. We found that the PFSP has a bird richness similar to large fragments of the region, although the most sensitive species and more demanding in the resources exploitation are less abundant compared to generalist species and to the most conserved fragments of the surroundings. In Chap. II, we evaluated the interaction between frugivorous birds and PFSP‟s ornithochoric plants. There was availability of attractive fruit throughout the year, with peak productivity between September and October, in line with the pre-reproductive period of birds and the arrival of migratory species. Despite the prevalence of generalist birds that disperse mainly small seeds of plants from the early succession stages, we found the PFSP has a diversified frugivorous bird-plant interaction network compared to other forest fragments of the State, due to the variety of available environments, connection with other surroundings fragments and its medium size and rounded shape, softening the matrix impact. In Chap. III, we evaluated the potential of bird perches in increasing the seed rain in an abandoned pasture within the PFSP limits. Therefore, we installed seed traps under natural perches (living trees) and artificial, noting the number of deposited seeds increased proportionally to the amount of landing perches structures. Natural perches also provided other resources for birds, such as fruits, insects and shelter, making them more attractive. We conclude that natural perches and artificial perches with more elaborate architecture showed greater efficiency in attracting seed-disperser birds and increasing the seed deposition, being the most recommended for this area recovery and for ecological restoration projects.

    This study started from an analysis and reflection on Teamwork, from the perspective of professionals from a Family Health Unit (FHU) in a town in the state of São Paulo. The purpose was show the work process, based on the perspective of integrated care, considering the conception of the role of each professional as an integral member of a team, for the production of care. It also shows the vision of these professionals about teamwork, as well as those factors that favors and influence in the relationships established in the work process. The present used a qualitative descriptive-analytical approach to character, whose participants were health professionals, entered a team in the "Strategy of Family Health". Although professionals have noted the importance of interdisciplinary character, its representations indicate that they develop work isolated and fragmented actions. Value the participation of different professions / professionals as team members; however, their representations are not revealing the interaction between their knowledge. It is understood that discussions about teamwork in the context of the family health strategy are crucial to bring about changes in the profile of the various professionals involved, because this implies a collective activity where each member puts their knowledge, feelings ne expectations due to a common objective, that is, in the production of a complete care.

    This dissertation presents a brief historical and an overview of Participatory Guarantee Systems (PGSs) experiences worldwide and draws up a sociological analysis concerning the process of organic regulation in Brazil. It also contains a case study of a PGS based on the Natural Agriculture Association of Campinas and Region (ANC, by its acronym in Portuguese), located in the municipality of Campinas, state of São Paulo, Brazil. For the historical review, the methodology included literature review, interviews with key actors related to the Brazilian agroecological movement and documental analysis. For the case study, the techniques employed were participatory observation during the field research, analysis of ANC´s documents and interviews with ANC s producers, focused on both individual and organizational trajectories. The study revealed that the participation of Civil Society in the regulation of organic production in Brazil, especially through the agroecological movement, was the main reason for the brazilian legislation to become the first one that recognized PGSs in the same level as Third Party Certifiers. The case study revealed that the experiences exchange and the continuous members capacitation are the main advantages of ANC´s PGS. On the other hand, the major challenges were to overcome bureaucracy as well as direct and indirect costs in order to maintain the PGS´s activities.

    Achieving resilience along the supply chain in today's turbulent business environment requires efforts from both internal and external elements of the company. Because Procurement is currently considered a boundary spanning function, it has become a primary facilitator in helping to create supply chain resilience. The purpose of this study is therefore to understand the role of Procurement in managing the intra- and inter-organisational issues needed to create supply chain resilience. To do so, a literature review was developed by following the systematic literature review method in which intra- and inter-organisational issues that could impact supply chain resilience were identified. These issues were grouped into eight general topics: knowledge acquired, inventory, product and technology for intraorganisational issues; and strategic sourcing, supply chain design, transportation and risk for inter-organisational issues. Dynamic capability (DC) view was also reviewed to offer a deeper analysis and fresh perspective on the empirical results. A multiple case study was conducted in four focal companies from different sectors, including two key suppliers from each one. After all interviews were transcribed, the data was added to the QDA Miner software in order to conduct a content analysis of within-cases and, subsequently, cross-case analysis. Following the theory elaboration defined by Ketokivi and Choi (2014), propositions were developed based on the empirical and theoretical findings through the rationale of the dynamic capability view. As a result, procurement structure and external inventory were found as additional organisational issues, and a new rationale is proposed to explain how Procurement can create supply chain resilience through dynamically managing and controlling the identified organisational issues. The primary theoretical contribution of this research is applying a new perspective to the issue of resilience. The development of these capabilities may help Procurement managers to better cope with current critical supply disruptions and hence help to achieve company survival and competitiveness.

    The research in performance measurement (PM) systems have reacted to changes in organizations environments. In recent years, in response to the pressures of society, the organizations are increasingly implementing sustainability practices. Following this context, this study aims to investigate empirically the changes in PM systems caused by the implementation of sustainability practices in organizations. The bibliometric studies and systematic literature review have showed that there is no clear relationship between the research on sustainability and PM systems. Hence, it is necessary to develop more empirical studies to close the identified gap. In the first research effort of this thesis, a case study was carried out in a company which is ranked as sustainability company in Brazil index. The empirical findings indicate that the PM system changes have occurred in three elements: performance measures, how the companies communicate their results, and the process of information management. These findings were the foundation for developing the survey, the second research effort. The survey was carried out in a population of 182 companies which publish sustainability reports in Brazil, according to the Global Reporting Initiative standards . After the data collection, 81 valid responses were received. The data analyzes demonstrate that the respondents who perceived change in PM systems work in companies which has more implemented environmental practices. Additionally, this perception is influenced by PM systems variables: use of social indicators, the relevance of social/environmental indicators, the new social/environmental performance indicators, the internal communication among all hierarchical classes of roles, the external communication to several groups of stakeholders, the use of benchmarking, the compliance with regulations issues, the information provided from PM system about social/environmental performance measures and the interpretation of the social/environmental performance indicator results. Therefore, the sustainability practices have acted as triggers for changes in performance measurement systems.

    As an outcome of the ethnography carried through among the Tenharim - a kagwahiva group from the Madeira river basin in Southern Amazon Rainforest - this dissertation's major point is the Mboatawa, a feast that takes place annually between June and August, and the ritual transformations. This work is, hence, an ethnography of the ritual metamorphosis triggered by two distinct aerophones called Yreru and Yrua, as well as the singing of the elders. Through these expressive elements present in the Mboatawa and the approach to the tenharim landscape, I develop an assay of the temporality emerged from the alterations provoked by the feast and the inherent transformation in their topography. However, the Mboatawa is not restrict to the expressive forms, but also to other domains, such as the chieftainship and Mutum (Myty-Nygwera) and the system of moieties Taravé (Kwandu).

    Given the large number of species of Bauhinia and great morphological similarity between them, it is necessary the development of robust analytical techniques in quality control of plants used as herbal medicines, since it is difficult to achieve the desired effects when using a different species as is the case of plant studied. Therefore, this study aimed to identify similarities between commercial preparations and the standard sample Bauhinia forficata Link. Obtained crude extracts of commercial samples and standard sample using different extracting phases. The extracts were analyzed using the technique of nuclear magnetic resonance (NMR) and principal component analysis (PCA) used for extraction and interpretation of the data obtained. As a result, we found that the extracting phases hexane, methanol and methanol / water, generated the most varied spectral profiles. Visual analysis of the samples suggests that there are at least four different samples in the data set. Moreover, by analyzing PCA can be concluded that all the samples are different from the standard sample. However, it is not possible to say whether or not the samples belong to the same species, since external causes as time and storage temperature, can cause chemical variability that are modeled by the PCA and thus further studies should be conducted in order to classify them. To do this we studied the feasibility of using second-order methods such as PARAFAC and MCR. The characteristics data didn t accord the requirements for use of these methods, such as trilinearity, blocking its application.

    Few studies are targeted concerning the chemistry of the secondary metabolism from endophytic fungi associated to edible fruits. In this sense, it is worth to explore the the microbial metabolic skills, particularly from the fungi species naturally present in this host, since a plethora of compounds from different biossintetic groups with diverse bioactivities may have been directly introduced to human diet. Therefore, the aim of the work encompassed the chemical and metabolic investigation of the fungus isolated from sympthomless apple fruits, the specie Talaromyces rugulosus, as well as the fungus Setophoma sp. isolated from healthy guava fruits. The study was based on the chemical prospecting of the fungal metabolism by means of OSMAC approach. In this step, besides the screening of known metabolites, the investigation was carried out in order to encounter new natural products biossintetized by the studied strains. Aiming to reach a fast and effective dectection, the UHPLC-HRMS based dereplication combined to dedicated database queries was extensively applied. The use of these integrated approaches allowed the establishment of a broad chemical profile owned to each microorganism and has led to the identification of seven new depsides produced by Setophoma sp. and novel halogenated alkaloids by T. rugulosus through spectroscopic data, chiefly NMR and HRMS-MS. In addition to these results, the induction of known perilenequinones produced by Setophoma sp. strain was observed when it was submitted to the co-cultive with other fungi species. Some of the novel poliketides showed moderate antimicrobial activity against S.aureus, while the perilenequinones comprised a seeming inhibition of some tested Penicillium species. Concerning T. rugulosus, it was also verified if the fungus showed to be skillfull in biotransformations of compounds naturally owned to apples chemical composition, such as flavonoids and organic acids. Whereas any product from this proposal was detected, a remarkable production of multicolanic acid was observed by the use of the tested substrates into the culture medium, suggesting a likely marker for this specie. Finally, taking into account the fact that fruits represent a rich source of nutrients for its associated microbial inhabitants, it is worth to consider that secondary metabolites biosynthesis in loco be favoured. Therefore it was proposed the monitoring of the most common metabolites produced by T. rugulosus into commercial apple extracts. The detection study was carried out by UHPLC-MS/MS via dynamic MRM experiments, which allowed the detection of compounds potentially produced by the fungus in the evaluated apple extracts.

    Estudos de expressão em genes potencialmente envolvidos no processo reprodutivo em Anastrepha obliqua (Diptera, Tephritidae)

    The majority of species in the genus Anastrepha is endemic to the Neotropics and many are of great economic importance because they inflict great damage to several different fruit crops. Brazil has low insertion in international markets because of the demand for quality products with no pesticide residues, which force the improvement of control techniques. Thus, an alternative to insect pests control is the Sterile Insect Technique (SIT), which reduces the pest population by mass release of sterile insects. However, sterilization by radiation has many side effects, reducing the competitiveness of released males relative to wild males. For this reason, different strategies have been used, such as the production of transgenic individuals not only in order to sterility but also increasing the vitality presented by these males compared to wild males. To accomplish that, an important approach could be the study of genes involved in the reproductive process. In this work, we selected nine candidate genes for expression studies of our transcriptome data, which have the potential of being involved in the reproductive process in Anastrepha because they belong to gene families that have already been associated to the reproductive process, and showed differential expression between the contrast of virgin and post-mating of transcriptome data in Anastrepha flies. Since no qPCR study has been done to date in Anastrepha, we tested several reference genes for normalization of expression data. The genes Rpl18, Rps17 and Ef1a were deemed suitable and used here to standardize studies of expression between life stages of A. obliqua. The qPCR gene expression analysis revealed interesting gene expression patterns for AttA, Obp56a and Obp99c, which increases the potential of these genes being involved in the reproductive process. Obp56a showed a higher expression in virgin females in contrast to postmating, whereas AttA and Obp99c showed higher expression in male in contrast to females, which may be interesting for genetic control techniques. We applied the RNAi silencing technique with AttA and Obp99c, aiming to generate information about the participation of these genes in reproduction. Thus, our results pointed for three candidate genes that could be interesting for population control techniques, with potential of being involved in the reproductive process, which stimulates further researches in Anastrepha obliqua.

    In this work the author intends to show an experience of implementation of alternative activities to traditional teaching of trigonometry in 9th year of Fundamental School (Brazilian curriculum). The theme choice came from the author's finding of difficulties presented by pupils in face of a great amount of formulas without meaning for them. The goal of these activities was to stimulate the students to make them construct their own knowledge, culminating in a meaningful learning. It was intended to formulate activities with the use of smartphones and tablets. The technological advance of cell phones has provided a range of different tools that fit in someone's palm and can be accessed immediately. Some of these tools provide the use of tablets and smartphones in the educational context, aiding student's learning in an innovative form, making it more pleasurable. All activities followed the guidelines of didactical engineering as research methodology. The activities were applied in a school were the author is a teacher.

    With advancing age, there is a tendency of loss of cognitive aspects such as memory, attention, learning new technologies and motor aspects such as loss of range of motion of the upper limbs. The literature points to investments made to investigate the use of virtual reality in cognitive and motor aspects, however, due to the few researches found on the topic, is one notable gap in terms of describing the training of motor skills of the member and higher cognitive skills using virtual reality applications. This research aimed to evaluate the use of virtual reality application KapMan® for training of motor skills of upper member and cognitive in institutionalized elderly. The research was performed in a long - term institution, located in a midsize city in the state of São Paulo. The participants in this study were six seniors and we used a questionnaire about participants - to make sure about their skills and understanding about the game - measurement of range of motion, heart rate and blood pressure, the DASH questionnaire was used and Mini - mental State Examination. Furthermore, adaptations in the original game KapMan® were made. The results indicated a reduction in execution time of activity between the first and last time, and an increase of the final score (score) obtained, leading to believe that the adjustments made in the game and the training of the proposed activity resulted in better performance of the elderly. There were no observable changes in variables heart rate and blood pressure. The data shows an improvement in pain and upper limb function, and increased range of motion of the upper limb of the elderly. As the cognitive aspects, four elderly have compatibility with cognitive disabilities and two do not have this loss. Nevertheless, the elderly understood, learned and developed motor skills of the upper limb and cognitive training with the proposed activity. Thus, the premise that the deployment of virtual reality applications help the training of motor skills and cognitive upper limb was confirmed.

    In this qualitative study, we aim to investigate the senses of learning English and the relationships established by elementary school students in the context of public school education with the world (with the transmitted/acquired knowledge in school, with the school, the classroom and everything that surrounds it), with the other (teachers and peers) and with themselves (their knowledge, their expectations, their goals and motives). Thus, the research focuses on understanding the meaning that the school has for students and the conceptions they have about the English language and its learning, considering the epistemic, personal and social dimensions of knowledge. It also seeks to identify the processes that structure the motivation to learn English and the mobilization to learn the language. The work is based on studies conducted by Bernard Charlot (2000, 2001, 2005) about the relationship to knowledge, which seek to understand how the subject categorizes and organizes their world, how they attribute meaning to their experience, especially their school experience. The theoretical basis of this research is also composed by principles and concepts that constitute the Activity Theory, developed by Vigotski (1980, 2001, 2005, 2007) and Leontiev (1978, 1984), as well as conceptions about motivation, within the area of language teaching and learning (DÖRNYEI, 2001; DÖRNYEI & USHIODA, 2013; GARDNER, 2002, 2010; DECI & RYAN, 2000; VIANA, 1990). Data collection involved classroom observations in two 6th grade classes of elementary school of two public schools in the state of São Paulo during the period of one year, and it included the following instruments: questionnaires, drawings produced by the students, researcher's field diaries and interviews. Through data analysis, we found that students recognize the role of the school as a learning space, but the relationship they establish with the institution is based on the valuing of relational/affective learnings. We observed that students begin the 6th grade with a positive perception of the English language and they are motivated to learn it, but in spite of this, there is neither mobilization nor establishment of personal sense, due to the mismatch between motives and purposes of the learning activities.

    The reason why Football was chosen as the subject of this study, was due to the great appreciation for this modality. For some time, the “dream of being a football player” was cultivated and very latent in my life, but for reasons of stature, I was unable to carry on this “dream”. At the University, in contact with studies about football, it became clear that the tactical aspect must prevail over the physical and technical aspect, that is, knowing how to read and interpret the game situations to respond in the most appropriate way to them is more important than that motor gestures and physical issues. And as Soccer is one of the elements of the Body Culture of Movement present in School Physical Education classes, it is the duty of the school to properly teach this modality, providing conditions for students, regardless of the desire to pursue a football career, to know how to interpret the game situations and make effective decisions before them, and for that it is necessary to break with a traditional teaching model, which prioritizes the motor gesture, and adopt a methodology that allows students to know how to read and interpret the game situations. The objective of my research is to analyze the quality of play of a 9th grade class in the individual, group and collective tactical dimensions, based on an intervention based on a didactic unit of Football based on Tactical Approaches. The present research will have as a methodological reference the Action Research. This methodology has as principles the observation of the object of study and the intervention to provide a change, which can be positive or negative. Action research starts from a social reality in order to modify this reality through pedagogical interventions, for this reason the integration of research and intervention is of fundamental importance. In this methodology, the researcher must constantly assume the role of researched and that of the group participant. For data collection, two instruments will be used, which are the diaries of classes and filming. And for data analysis we will use the Team Sports Performance Assessment Procedure (TSAP) tool, which aims to produce valid information to assess student performance in invasion sports. Classes were held with themes related to the tactical situations of football, and the application of TSAP was carried out in two moments, the first before the didactic unit classes and the second was after the end of this unit. From the data from the Class Diaries and the TSAP it was possible to identify an improvement in the quality of the students' game in the individual, group and collective tactical dimensions.

    Currently, in Brazil, there has been noticed increases of agrochemicals use, in spite the trend of using less toxic products. Pyrethroids appear as the option due to low toxicity displayed to birds and mammals, and the low bioaccumulation along the trophic chain. The pyrethroid insecticide λ-cyhalothrin (LCH) is used against a variety of arthropods. These chemicals can reach aquatic environments either by direct application in fish farms to kill parasites or by runoff after agricultural and domestic use, then affecting non-target organisms. We dealt with evaluation of antioxidant responses of matrinxã, Brycon amazonicus, exposed to LCH (TrincaCaps® DVA) and its recovery, since this is a freshwater fish relevantly farmed in Brazil. Twelve fish (n=12) were exposed to 0.65 μgL-1 (10% of the LC50;96h) for 96 hours and allowed to recover in a xenobiotic free water for 7 days. Hematological, osmoregulatory, antioxidant, neurotoxic, histologic and genotoxic effects were evaluated after sub-lethal exposure and recovery. LCH was extremely toxic to B. amazonicus since the LC50;96h was below 0.1 mgL-1. After the exposure span, fish exhibited impairment of respiratory functions and hypovolemia; the hematological parameters were not completely reestablished, despite a tendency to recover. The osmotic balance was affected after exposure, and it was not completely restored after recovery. The activity of brain acetylcholinesterase did not depict any change after both evaluation periods. Antioxidant defenses were activated in liver, kidney and gills, but this fact was not enough to prevent lipid peroxidation. After recovery, some defenses remained activated; nevertheless no lipid peroxidation was observed in any tissue. Histological parameters indicated liver and kidney injury, but no one was observed in gills. The kidney morphology was severely affected, but was reestablished after recovery; an opposite response was observed in liver. Micronuclei and nuclear alterations in erythrocytes were not observed after either exposure or recovery. We call attention to the hepatotoxic and nephrotoxic potential of LCH in B. amazonicus, emphasizing the importance of substantial studies to ground its use regulations in agriculture and aquaculture activities, since the set of injuries observed poses risk to this fish species.

    Brazil remains the world's largest orange producer, accounting for 32% of the total production of oranges and 50% orange juice. The State of São Paulo holds 97% of Brazilian exports of orange juice, possessing one of the largest citrus producing areas of the world. Citrus plants can be affected by various pathogenic agents which highlights the fungus Colletotrichum acutatum, causal agent of citrus post-bloom fruit dropwhich under certain environmental conditions, is in a limiting factor in many citrus production areas. Given the above and seen the importance of disease in the cultivation of citrus, realizes the need for information related to the chemical study of C. acutatum. Thus, this study presents the chemical study of fungal plant pathogen, in addition, discusses the study of plant-microbe interactions, identifying volatiles by HS-SPME-GC-MS as well as characteristic signals compounds produced by plants when infected. Chemical studies of C. acutatum to the isolation of certain diketopiperazines, phenolic compounds, steroids, nucleosides and glycerides. In order to encourage the production of metabolites by the fungus and understand more your metabolism, some modulators (chemical and epigenetic) were used, in addition to the growth of microorganisms in mixed cultures, where it was possible to isolate some metabolites such as 2,5-dihidroximetilfurano and IAA. Aiming to observe the behavior of the flowers as the production of metabolites when infected, the study of plant-fungus interaction, where the pathogen was inoculated in flowers of Citrus sinensis, and these were collected at 2, 4 and 7 days. The volatile components of infected flowers were identified by HS-SPME-GC-MS and compared with the healthy flowers. A methodology for biological assays as mycelial growth, spore germination and appressorium formation was implemented.

    The need to ensure the quality and safety of food becomes increasingly a concern of the entire food production chain, from primary production to final consumption. Feed industry is an important link in this chain, because the food given to livestock can influence the quality and safety of animal products. To ensure food safety adoption of Good Manufacturing Practices (GMP), which, for the animal feed industry has become mandatory implementation in Brazil, from 2003 is required, and preventive approach programs like Hazard Analysis and Critical Control Points (HACCP), whose implementation is not mandatory. This dissertation analyzes the internal and external impacts of the implementation of GMP / HACCP factories in the feed industry associated to Sindirações as well as the perceived difficulties during deployment. We conducted a survey research (survey), through a questionnaire sent to companies, yielding 60 response units. The data were analyzed in order to characterize companies, test possible correlations between the study variables and evaluate corporate groupings (clusters) with similar characteristics. Cluster analysis showed three groups, distinguished from each other mainly by the size of the unit and certifications standards for food safety. Although the quality of the product is a general requirement of the sector, the understanding that the adoption of programs to ensure the safety of foods is important for product quality and essential to the quality of food of animal origin food supplied to the final consumer does not seem to be unanimous in researching industry. It was observed that the plants that meet the most demanding markets tend to adopt these programs as well as certification. The main internal impacts, reported after the implementation of GMP / HACCP have been improvements in the occurrence of food security issues and improving the level of training of production employees, with respect to external impacts, the most cited were improved image brand and the improvement in customer satisfaction.
