The Statistical Process Control (SPC) is recognized in the literature as one of the main tools for controlling and improving the quality and productivity. The control chart is a central element of the SPC; and these, statistical tools whose efficiency depends on certain skills and organizational behavior. With regard to the results to the organization, it is observed that the use of control charts can be divided into two groups: those that can be directly attributed to reduced variability called hard; and those associated with the motivational aspects, or organic, called Soft. Despite the arguments in favor of SPC survey, a study conducted in the automotive sector shows that about 70% of companies have some difficulty in conducting their activities related to the SPC. On this, the literature indicates that factors related to methodological, statistical and managerial aspects of control charts of the implementation process are conditions for the success of a structured plan of implementation of the SPC. Given this situation, it is objective of this thesis contribute to an effective use of control charts by national companies, and to advances in research. To this end, we opted for a field survey to capture and describe the perceptions of experts who use control charts and working in the automotive industry. The field research was structured in three basic dimensions - statistics, methodology and management, and the results achieved by the use of the SPC, divided into Soft and Hard. The method used was based on a survey, which has a population of interest was the managers of SPC programs that use the control charts for more than 01 years in the auto parts industry. This survey was sent to 98 individuals in the population of interest, identified in the Official Guide Auto parts Industry (2014), which resulted in 37 questionnaires and valid for analysis. The results of this field research validated the hypotheses in part the theoretical framework, but showed, besides the complexity and importance of methodological and managerial aspects in the implementation of the SPC, there is a significant gap between theory and practice. This may partly be explained by the dissonance between the main scientific advances in the field, especially in the statistical aspects, and the controversies about the real benefits of SPC program. As a result of this thesis is recommended that field research has been done for that to report real success stories of the SPC; whose cases are examined in depth so that good practice is disseminated in the academic environment.

This research aims to outline and scrutinize the set of musical practices and repertoires widespread among the Macushi, an indigenous population of Karib linguistic affiliation who currently inhabit the fields and valleys of the basins of Branco and Rupununi rivers, a region that is politically divided between Brazil and Guiana. This investigation is temporally restricted to the last decade – between 2005-2015 –, and geographically restricted to the population situated on the Brazilian side, more specifically on the territory currently known as Raposa Serra do Sol. This study intended to detail the practices, significations and meanings attributed to different musical rhythms and repertoires of Makuxi in order to understand what kind of motivational factors were implicated in the the spread of forró rhythms and in the reworking of traditional musical rhythms, notably the parixara and the tukui, in a political context in which such musical repertoires were reinterpreted and used as "cultural performances".

The sugarcane has great economic importance in Brazil. To keep productivity several biotic and abiotic factors can positively or negatively influence. Among them, weeds, nematodes and synergistic action between pesticides to control both can be cited. Thus, the present work aimed at studying possible common weeds in the mechanized harvesting system that can serve as hosts for the root knot nematode: Meloidogyne incognita and / or M. javanica and study the interaction between herbicides and nematicides used in the groove planting of sugarcane. Two experiments were carried in a greenhouse at the Agricultural Sciences Center (CCA-UFSCar), Araras, SP. The first experiment evaluated the host status ten weeds, as follows: Ipomoea triloba (Dammer), Merremia aegyptia (L.) Urban, Luffa aegyptiaca Mill, Euphorbia heterophylla L., Ricinus communis L., Crotalaria spectabilis Roth, Mucuna aterrima ( Piper & Tracy) Holland, Chloris polydactyla (L.) Sw., Digitaria horizontalis Willd., Urochloa decumbens (Stapf) RD Webster and the control (tomato Santa Cruz Kada) when inoculated with M. incognita or M. javanica in a completely randomized design in a factorial 11 x 2, with six repetitions. The plants were inoculated with 2.000 eggs and J2, and there were three plants per plot (6.000 eggs and J2 per pot - repetition). Sixty days after inoculation (DAI) the plants were removed and evaluated according to the reproduction factor (FR), final nematodes population (PF) and reproduction index (IR). In the second experiment the effect of interaction between two nematicides applied in contact with the stalks was evaluated. The nematicides tested were: benfuracarb (5,0 L ha-1) and carbofuran (50 Kg ha-1), and the herbicides applied preemergence of culture were: sulfentrazone (1,6 L p.c. ha-1), diuron + hexazinone (2,5 Kg ha1), saflufenacil (0,14 Kg p.c. ha-1) and amicarbazone (1,5 Kg p.c. ha-1). The experiment was carried in a completely randomized design in a factorial 15 x 5, with four replications in three sugarcane varieties (RB867515, RB975952 and RB975201). The first factor was corresponded to the 15 treatments and the second, to the five evaluation periods. Evaluations of intoxication symptoms were performed at 7, 15, 30, 45 and 60 days after emergence (DAE) of culture. In the last assessment biometric parameters height (cm), leaf area (cm²) and dry biomass of the aerial part (g) were evaluated. Regarding to the host status of weeds, it was found that L. aegyptiaca behaved as host of both nematodes, with FR > 1, higher than the control. The D. horizontalis was classified as host of M. incognita and non-host of M. javanica. C. spectabilis had the lowest FR and PF. R. communis and I. triloba present galls when inoculated with M. incognita, but were not considered host for presenting FR < 1. None of the weeds tested was considered immune, that is, with RF = 0. Regarding the interaction of herbicides and nematicides in all treatments, plants recover 60 DAE, and in treatments with the use of sulfentrazone increase in symptoms of poisoning was observed. As for the biometric parameters evaluated at 60 DAE, there was no statistical difference only in the variety RB867515 for height. In this case, the treatments amicarbazone / benfuracarb and amicarbazone / carbofuran plants were higher than the control and other interactions.

In 2001, Larissa Mies Bombardi performed a case study regarding the Agrarian Inspection Law, and more specifically the Capivari agrarian core, founed in the 1960s and that became a rural neighborhood. The present paperwork seeks a reviewing of this case study in order to approach the economic and cultural changes expressed through spacial transformations that took place between 2001 through 2015. The goal consisted in understanding the farming production processes in this core and the trasnformations ocurred since Bombardi's study, upon the concept of reproducting peasantry, of the peasants as a reproducting unit. For the conceiving of this work, first and foremost, a study of Larissa Bombardi's “O Bairro Reforma Agrária e o processo de territorialização camponesa” took place, hence the book was taken as primary reference. After, there was the accomplishment of field research, with numerous interviews held with different profiles of local dwellers. Beyond that, the discussion regarding the changes and transformations that took place since Bombardi's study and the neighborhood and the peasantry's current situation, as of 2015. After that, there's a reflection concerning education in rural schools with a singular perspective that englobes the peasant reality. Thus, it's concluded that the peasantry's deal shows it's modifications and adaptations as they happened through the years, given the numerous difficulties regarding their reproduction, as well as “mechanisms” adopted for survival and continuity of this class as expressed by the different dweller profiles compiled in this paperwork. Furthermore, it's concluded that such cultural and social modifications impact directly in the neighborhood's configuration.

This study presents an analysis of the diversity of forms on organic food production commercialization in Vitoria (ES), and the discussion about this research theme. The goal is to understand how and under which conditions the market valorizes the local production, strengthening the ecological family production and the food sovereignty. The research methodology took into consideration quantitative and qualitative data, utilizing available public information and data acquired in field research. The evaluation shows that organic products are commercialized by direct sales, in organic outdoor markets and fair markets, and by indirect sales in supermarkets, specialized stores and restaurants. Among the evaluated commercialization channels, were the organic product outdoor markets that showed a greater product diversity, in addition to a better price, which were up to five times lower than in the supermarkets. Furthermore, organic product prices, when compared to the equivalent conventional ones, always showed higher values in indirect sales. However, among conventional and organic street markets, organic products prices were higher, equal or smaller than their conventional equivalents. Therefore, it concludes that this commercialization channel valorizes the organic family production, promoting the empowerment of family producers and the access to healthful alimentation for local consumers.

Violence is a current topic, and violence perpetrated by intimate partners is growing concern of social, legal, and health policy. The subject is already configured a public health problem, considering the physical and emotional harm caused to the victim, and study data refer to women victims of domestic violence seeking up to six times more for the health service. Pregnancy can be an increase of the risk of violence against women according to some studies, can change the default for the frequency and severity during this period or even be initiated at this stage of a woman's life. Still, this type of violence ends up in invisibility in health services, and can cause risks to maternal and fetal health. Objective: To discuss the scientific production in Brazil in the period 2010 to 2015 regarding the children's maternal outcomes during gestation and postpartum women victims of violence perpetrated by an intimate partner. Methods: We used the scientific literature integrative review with cover articles in Portuguese, English and Spanish available in CINAHL databases, Scielo and BVS published in the periods 2010-2015 through descriptors in Portuguese and English "violence against women and pregnancy "," domestic violence and pregnancy. " Results: There was negative repercussions resulting from VPI, the analyzed studies bring these can affect both the pregnancy, such as puerperal, with higher occurrence of risk among women with unplanned pregnancy, abortion practice, presenting also high rates of gestational and postpartum depression, at high risk of suicide, poor quality in prenatal care, Fetal death (neo and postnatal) and increased risk of low birth weight. Conclusion: The knowledge of these data IPV during pregnancy by health professionals can help prevent negative outcomes for women's health and fetal development, and must become concrete action of primary care and specialized in prenatal care.

In recent years, companies have used Artificial Intelligence (AI) techniques to facilitate the decisionmaking process in manufacturing systems. The use of these techniques allows increased performance of Flexible Manufacturing System (FMS). The automation of the process using computational resources allows a deeper analysis of the system conditions, which sometimes result in a better decision taking. In this sense, the Fuzzy Logic has been engaged to carry out this task, because it has the characteristic of dealing easily with inaccurate information and encoding knowledge specialist in Fuzzy rules. However, as soon as the system complexity increases, the task of generating a Fuzzy Rule Base (FRB) appropriate to the proposed system becomes increasingly difficult. To assist this process of generation of the FRB, several techniques can be used and among them stand out the search technique called Evolutionary Algorithm (EA). The EA is used, for example, for tuning the FRB of the FMS through the reduction of the optimization variables values as Makespan or Tardiness. In the case of variable called Makespan, the tuning occurs when the EA generates an FRB that reduces the makespan values of a FMS. However, the construction of the EA that effectively generates a tuning FRB is not trivial. It is required to be in the process, the construction of various EA with different selection methods and different mutation rates among other settings until an appropriate EA for a given situation appears. Therefore, in this study we aim to build an environment configuration and performance analysis of EAs in order to define the tuning FRB of the Fuzzy Control System of an FMS, i.e., it is intended to investigate how the EA ideal parameter scenario used for tuning the FRB of the said control system. In this study, the used EA was an extension of Genetic Algorithm (GA). For implementing the proposal, an evolutionary system for configuration and analysis of this variant of the GA was created. In this system, entitled "EvolSys - Evolutionary System" parameters of the system as Number of Input Variables of FRB, Number of Output Variables of FRB, Population Size, Mutation Rate and the EA Crossover Rate, among others are configured and then, one FRB is generated. Using this, there is an EA analysis of the possibility for choosing a FRB that will provide the reduction of makespan in FMS. Consequently, through this study, we may conclude that the use of EAs in collaboration with Fuzzy system may become an important tool for turning the system responsibility to the sequences of an FMS operation. Accordingly, the environment created meets the configuration step and analysis of EAs.

This thesis describes a study of the electronic charge transport properties in antimony-doped tin oxide (ATO) ultrathin films, prepared by two different methods: by colloidal deposition process (CDP) and by pulsed electron deposition (PED). In order to determine the ultrathin films electronic transport mechanism properties and to elaborate a model for this mechanism, microstructural analysis and electrical characterization were carried out. The samples were studied by X-ray diffraction (DRX), transmission electron microscopy operating in high resolution (HRTEM), scanning electron microscopy (FEG-SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), ellipsometry, electrical resistivity measurements were made using the four-point probe approach from 20 to 300K and Hall effect measurements were made at room temperature. Regarding the CDP, DRX and HRTEM show nanocrystals with the cassiterite phase, highly crystalline nanoparticles and average crystal size of 6.5x4.4 nm. The FEG-SEM and AFM images indicate a crack-free deposition, constant thickness over the substrate cross-section and low roughness. Moreover, the electrical properties evaluation suggest that the experimental data fits the bi-dimensional Mott’s Law and that the electron hopping is in the order of the nanoparticles size. Concerning the PED, DRX indicates only the cassiterite phase structure and a preferential thin film growth at [110] direction, the FEG-SEM and AFM images show a homogeneous deposition and that the thickness is constant over the substrate cross-section, with low roughness. Besides, electrical characterization reveals a metal-semiconductor transition, that the experimental data fits the tridimensional Mott’s Law and that the electron hopping is in the order of the nanoparticles size. Thus, it is proposed that the charge transport mechanism obey the Mott’s Law, which occurs through the nanocrystals surfaces, i.e., the electron hooping occurs at preferential facets where there is Sb segregation.

The microbial community plays an essential role in maintaining the ecological balance of soil. Interactions between microorganisms and plants have a major influence on the nutrition and health of the latter, and growth-promoting rhizobacteria can be used to improve plant development through a wide range of mechanisms. Therefore, the objective of the present study was to evaluate bacteria as biological control agents to Phytophthora nicotianae and as growthpromoting agents for citrus rootstocks. Altogether were evaluated 30 bacterial isolates, 11 Bacillus spp., 11 actinobacteria, and 8 lactic acid bacteria. For P. nicotianae control tests at first was performed an bioassay with alfalfa seedling in order to select the most promising bacterial isolates for the biocontrol and, posteriorly, the best isolates were applied in Sunki mandarin (Citrus sunki Hort. ex Tan), and rangpur (Citrus × limonia Osbeck) by seeds and substrate microbiolization methods. It was evaluated the number of surviving plants, at 90 days after sowing and inoculation. The same Isolates also were evaluated in vitro for indoleacetic acid production, phosphate solubilization, and nitrogen (N) fixation. In vivo testing consisted of growth promotion trials of the bacterial isolates that yielded the best results on in vitro tests with three rootstocks: Swingle citrumelo [Citrus × paradisi Macfad cv. Duncan × Poncirus trifoliata (L.) Raf.], Sunki mandarin and rangpur. The parameters of interest were height, number of leaves, stem diameter, shoot and root dry mass, and total dry mass at 150 days after germination. The results showed that alfalfa seedling bioassay vi was able to evaluate the potential for biocontrol of bacterial isolates against to P. nicotianae, BL06 and BL12 (both lactic acid bacteria) showed potential to be used as biocontrol agents of disease, independently from the application method. BM16 and CPMO4 were able to promote growth of Swingle citrumelo. In Sunki mandarin plants, the best treatment results were obtained with BM17 (Bacillus sp.) and ACT11 (actinobacteria). For Rangpur lime rootstock, only BM05 (Bacillus sp.) was able to promote increase in two parameters assessed, height and number of leaves.

Defects play a fundamental issue on physical properties of wide bandgap semiconductors (WBS) due to the possibility of application in high temperature. This work shows the features of the defects in di erent kind of WBS grown/synthesized by solid state reaction, Pechini method and Molecular Beam Epitaxy. First we investigated the structural and optical properties of erbium- and manganese-doped strontium aluminates (SrAl2O4). The fundamental optical transitions due to Er3+ and Mn2+ are typical features of the well-diluted doping process. A signi cant enhancement of the Er3+ optical emission band at 1530 nm was observed when the matrix is co-doped with Mn. A model of energy transfer mechanism from Mn2+ to Er3+ is proposed to explain the experimental results. We present also the e ect of preparation and annealing conditions on the properties of Nb2O5. The increase of oxygen vacancies causes an inrreversible phase transition from pseudohexagonal to orthorhombic phase, and they are responsible for the increase in the e ective magnetic moments related to paramagnetic behavior. Finally, we explore the e ects of the interfaces imperfections of quantum wells of cubic GaN alloys. An indication of localized states in low temperature is observed. A decrease of this e ects happens when we increase the number of interfaces. Furthermore, magneto-PL measurements show a higher spin polarizations in the donor-acceptor impurities in the bulk of c-GaN corroborate for the importance of the defects. This work shows that the defects engineering in WBS are fundametal for developing new technologies in spintronics and optoelectronic eld.

The Brazilian market for dairy products is highly competitive and is still dominated by multinationals. Thus, it's essential that the national companies to invest in operational efficiency in order to compete successfully. Therefore, this research focuses in a small dairy company of the state of Pará, whose distribution system requires periodic stops for battery recharging. Moreover, the system is characterized by multiple periods and multiple time windows. To our knowledge, so far the literature hasn't presented a directly applicable methodology for the treatmeant of the application with similar characteristics. Therefore, aiming to provide more effective solutions than the ones in practice, a mixed integer linear model was developed to describe (and solve) the problem as a vehicle routing problem with time window constraints, multi-period and periodic stops for recharging. The results showed that the model adequately describes the distribution of the company, and the obtained solutions are better than those currently practiced. Furthermore, the model shows good performance within 3600 seconds of computational time for instances of 40 customers, 1 vehicle and 1 and 2 recharging stations. Aiming to tackle with larger examples, we developed a mathematical programming heuristic Relax-and-Fix to solve the model. It was also tested adapting a similar model present in the literature in order to analyze if the relaxation of some restrictions have a positive impact on the quality of the solutions. Finally, we propose a location-distribution model for recharging stations in order to examine whether the addition of new stations produce significant improvements in the solutions.

The quest for increased productivity has become a mantra repeated ad nauseam in many companies immersed in a globalized market. In this context, many computational techniques have becoming more popular, gaining followers, aiding and refining the process of decision-making. Among the various techniques available, the discrete event simulation stands out, as it allows studying the behavior of systems, real or not, in various conditions, allowing hypotheses to be tested without physical and financial resources are used. In the case of the animal feed industry, this technique becomes a very important tool, especially in the short term planning which involves the management of the floor operations. The animal feed industry is part of the agribusiness chain, and as such, has its inputs internationally listed, commodities, thus effectively managing its installed capacity is a strategic advantage for differentiation before the market needs in terms of cost, time and quality. In this sense, the objective of this study was to develop a discrete simulation model to assist the decision-making process on increasing the rate of bagging an animal feed industry, located in the state of São Paulo. For this study it has been used the Arena® software, Rockwell Software, and as a method of research modeling and simulation, and the simulation model development stages followed the methodology proposed by Law and Kelton (2000) and Banks (2010). Data were always collected with the same operator at the same time. As a result of simulation of the proposed model was possible to analyze different scenarios, assessing the dynamics of the system and with the performance indicators the equipment utilization rate, the amount of products produced and the consumption of electricity and natural gas per ton of product produced. Whereas the use of discrete simulation in animal feed industry belonging to the process industry and with hybrid production process, could be used due to the approach proposed by Spieckmann and Stobbe (2012).

This work has as its theme the life and academic career of Dermeval Saviani and their contributions to the educational debate in Brazil, from the consideration that he became an intellectual proponent. He’s graduated in Philosophy from the Pontifical Catholic University of São Paulo (PUC-SP), where he also received his doctorate; Saviani is now professor emeritus at the State University of Campinas (UNICAMP). The research is justified by the many legacies that Dermeval Saviani brings to the Brazilian education, which are present in teaching and research, including an extensive publication in the areas of Philosophy of Education, Educational Law and History of Education. The objectives of this research are: to highlight the key moments of life and academic career of Dermeval Saviani, linking these events to the historical context, its research and production as well as the development process of the postgraduate studies in Education in Brazil; to discuss the concepts of ‘System’, ‘Educational Work’ and ‘Social Practice’ in the Dermeval Saviani’s work and which is his conception of ‘Education’ and ‘School’; to reflect about the role and contributions of Dermeval Saviani in the educational debate in Brazil, including his role in the organization of study and research groups, its proposal for a preliminary draft bill of Directives and Bases of National Education Law in the 1980s, just like the Historical-Critical Pedagogy’s perspective; to understand the Saviani’s role as intellectual proponent and organizer of the research field of the Brazilian History of Education. For the sources to deal with biographical and institutional aspects, we resort to autobiographical texts and authors who lived with Demerval Saviani ones, whether on condition of workmates and students, both as students and supervised by him. To address the above concepts, the sources are their own works. Regarding the methodological approach, we use the following categories: historicity, totality and contradiction and the following concepts: political culture, networks and/or elementary structures of sociability and solidarity of age, generation and study — important elements for the study the history of intellectuals. We consider that Dermeval Saviani, for its history, surpassed the teacher, researcher and author characteristics, constituting himself as intellectual, as evidenced by their engagement and the socially recognized function that he performs linked to scientific and philosophical spheres and educational-cultural and policy ones.

The oxides Mn3O4, LiMn2O4and their doped derivatives, LiMnij98Gaojo2O3j98Sojo2, LiMni,9oGao,ioO3,9oSo,io, LiMni,98Alo,o2O3,98So,o2 and LiMni,9oAlo,ioO3,9oSo,io were produced by means of an alternative route: the microwave-assisted solid-state synthesis. Mn3O4 was produced from an electrolytically obtained s-MnO2, by using microwave heating for 5 min. For LiMn2O4 and doped derivatives, solid mixtures of LiOH.H2O and s-MnO2, or LiOH.H2O and Mn3O4 were microwave heated for varying times (3 to 5 min). The synthesis precursors and the final products were characterized by means of X-rays diffractometry (XDR), thermogravimetry (TG), diferential thermogravimetric analysis (DTA), Fourier transform infrared (FTIR) and Raman spectroscopies, and scanning electron microscopy (SEM). XRD results indicated that, for LiMn2O4 and doped derivatives, the best synthesis conditions were achieved when using Mn3O4 as the precursor, i5o mg of reaction mixture, and synthesis time of 2.5 min. Quantified by XRD analyses, the materials presented secondary phases resulting in 8i - 93% mass percentage of the LiMn2O4 phase for the doped materials, and 92% for the non-doped material. For comparison, a commercial material was analyzed, resulting in 93% for the LiMn2O4 phase. Electrochemical characterizations were performed for the produced Mn3O4 e LiMn2O4 by means of cyclic voltammetry and galvanostatic charge-discharge tests, employing electrodes constituted by 85% oxide / io% acetylene black / 5% PVDF. Tested as supercapacitor, the Mn3O4, having average size particles of 35o nm, furnished specific capacitance of 2o6 F g4 and considerable electrochemical stability with charge retention of -60% after 5ooo cycles of charge and discharge. Tested as lithium-ion battery cathodes, all the lithium manganese oxides presented charge-discharge profiles characteristic of the LiMn2O4, furnishing specific capacity values in the range 87 - 108 mA h g-1. Contrary to the expectations, the material presenting the best electrochemical stability was the non-doped LiMn2O4, with charge retention of 76% after 200 cycles of charge and discharge.

This research aims to identify the teacher's knowledge announced by a group of teachers Initial Years of elementary school (1st to 3rd grade), linked to PNAIC (National Pact for Literacy Certain Age) in 2014 in the city of Sumaré - SP, through the detailed planning by a collective reflection and realization of a geometry activity developed in the classroom. This study, of qualitative nature, are based on participatory research, specifically action research, in view of the proposal for an intervention in the group studied. For the analysis of data produced by the teachers, the content analysis by the very nature of such data was used, the main landmarks references Bardin (1977) and Franco (2005) and for reasons of narrative, which constitute the data from this survey, we rely on Cunha (1997), Souza (2006) and Galvão (2005). The issue of teaching knowledge which is another aspect discussed in this work is grounded by the studies of Tardif (2011), Gauthier (1998) and other researchers dealing with the subject. The perspective is adopted in this research is an investigative work and that does not close at the time of analysis, and opening to the continuity of the reflections that now will be brought here. The object of study is seated in the triad: teaching knowledge, curriculum and teaching of geometry, with the theoretical foundation Silva (2010) in the curriculum conceptions, Leme da Silva and Valente (2014), Lorenzato (2011) and Fainguelernt (1999) in thinking about the geometry of education as well as the theoretical development of Piaget and Inhelder (1993) and Van Hiele (1990). Presented with this dissertation contributions to the continued discussion of teaching knowledge in the educational context, valuing the voice of the teacher of Primary Education Years Initials. As conclusions, we have the teaching knowledge arising announced by the teachers of vocational training, as well as disciplinary, curricular and experiential knowledge in the analyzed narratives. We bring to this indicative study for teacher continuing education concerning the reflective professional attitude and also to learn experiential as knowledge important to be considered in academic research as well as in their own continuing education of teachers.

The tuberculosis is characterized as a serious decease and affect the poorest regions of the world. Brazil occupies the 16th place in absolute numbers of cases. According to the Ministry of Health people on the streets are 67 times more likely to get sick from tuberculosis compared to the general population. This population is characterized by extreme poverty, interrupted or weak family bond and lack of residence, using the public places and degraded areas as their housing and sustenance. In 2011, the Ministry of Health implemented Street Clinic Teams as a care mode linked to primary health care, to address the different demands and health needs of the population in the streets. The teams offer “on the spot” and itinerantly, comprehensive health care for these people. The objective of this study was the analyses of sense production effect of the street clinic teams regarding to the care of people with tuberculosis. It is a qualitative assessment which took place at São Paulo’s central region. Six individuals took part in this study. The inclusion criteria: Team Nurses, Epidemiologic Surveillance Nurses, Technical Assessors who operate within street clinic teams, who agreed on signing the informed consent. A scripted semi-structured interview was applied for data collection, utilizing an audio recorder in all recorded interviews. The results emerged in four discursive blocks: characterization of care; service structure for TB patient’s care; incentives: cure x decease maintenance and the organization of work. The conclusion is that the care model in use by the investigate teams contribute to guaranteeing access to care, thus increasing early diagnosis, treatment, monitoring and cure of tuberculosis among that population.

The aim was to evaluate the degree of information literacy of undergraduate students of Federal University of São Carlos (UFSCar), born in the mid- 90s, as known as the Google generation. Using the survey method, we elaborated a questionnaire subsequently applied online, using Google's software platform, "googleforms", that seeks to analyse the information behaviour of students, considering their different undergraduate course. The research objetives were to: identify how students seek information to meet their needs, mapping what supplies they use and how they use them, not only sources of information in physical supports, such as books, printed periodicals, but on digital supports, such as databases, electronic books (e-books), among other sources; and find out what is the level of information literacy among the participants. Another dimension also addressed, was how respondents see librarians and the library environment as a study area and social environment. The questionnaire included eight multiple-choice questions , six of these also having an open field for comments. As results, we had 216 replies, 1% Agricultural Sciences 13% Biological Sciences 15% Human Sciences 25% Technology and Exact Sciences 11% Health Sciences 25% Engineering , 11% Linguistics, Literature , Arts. As predicted, when confronting with the previously read literature on the subject, we found that respondents most frequently used sources of information in digital format. However, they do not demonstrate full knowledge of search tools, although the information is found faster, students show difficulties in filtering the information retrieved. When comparing the use of printed and digital journals, the difference is clear-cut: 74% of students say they have used "few times" (30%) or "never" (44%) printed journals, and only 1% say they have used them "always", and "often " (8%). But when it comes from the same source in digital form, this figure rises to 26% ( "always" 14% and "often" 12%) , while the number of respondents who say they have used "few times" and "never" added are 56% , 20% and 36% respectively. Another result that points out the difficulty in filtering the data, showing a low level of information literacy is the lack of knowledge of the tools available to assist in searches: when asked up search strategies, only 6 % use specialized thesaurus, the strategies that they use the most are looking at the first three pages of results and using quotes and Google operators (44% and 55% , respectively) , with 38 % admitting not use any search strategy . The vision that this new generation has in relation to the library environment is still more traditional, which is seen as place to be quieter and conducive to study, 68% said that they used the library space "a few times" (29%) or "never" (39% ) as a leisure space. As the research participants overwhelmingly reported having searched the librarians in University Library "few times" (26%) or "never" (61%), we can conclude that they do not see librarians as professional to help them with their studies, information search and retrieval.
