The object of this study is the perceptions and meanings attributed to the public bank employment by employees of a federal bank. The 1990s were a decade of dramatic changes, marked by fusions, acquisitions and privatizations of public banks, intensification of work through expressive extinctions of formal jobs, precariousness of work relations, outsourcing and wage patterns deterioration and, at the same time, profits recovering at the end of the period. Thus, this study aimed to investigate and analyze how the employees of the target bank perceive bank work after the changes produced by the 1990s restructuring process. The first step was to analyze the productive restructuring process on the sector and its implications on work and workers. The second step was to try to characterize the major facts and changes occurred in the bank during the 1990s and early 2000s, via analysis of documents available at Centro de Documentação do Sindicato dos Bancários de São Paulo (documentation department of to the bank workers union in São Paulo). Finally, semistructured interviews were carried out with two groups of workers; group one consisted of ten clerks, staff hired up to 1989, who went through the sector restructuring; group two consisted of ten bank technicians, representing the new generation of bank workers, hired after the 1998 recruitment process. We started from the hypothesis that the mode how the public bank work is perceived by bank workers was negatively affected by changes occurred in the sector in the 1990s, which impacted on the employees mode of being and acting. As a second hypothesis, we believe that such re-signification can only be understood in the light of a process of significant ideological and institutional changes inherent to the flexible capitalism. We found that, for the new generation of bank workers, the perception originated from a synchronic comparison, where the job appears as an alternative to temporary, unstable or flexible work experiences, seems to shape the perception originated from a diachronic analysis, which evinces the historical losses of bank work. Increasing individualism, bradescalização of relations, creation of castes, hierarchical seduction in a context of limited possibilities of career ascension and basic rate of pay deterioration, and reduction of trade union involvement were elements explored by the analysis, which revealed that, considering what remained and what has changed, the stability issue seems to be the central element in the perception and meaning attributed do work, for both groups of workers. Thus, a process involving disruptions and continuities characterizes the re-signification of public bank employment. The disruptions, insofar as the meaning of work is no longer supported by the combination stability-status-wage and through the attenuation of the sense of belonging to a professional category. The continuities, insofar as the stability associated to employment keeps and increases its importance against the current configuration of the world of work, as well by the return and intensification of a trend already present in the pre-restructuring, represented by the idea of temporariness of bank employment.

Structural masonry buildings are being increasingly employed in construction. Well established for low-income buildings and with small insterspace, the system of structural walls has been gaining elbow room on the civil building industry. The great use of this structured system is due to the fact that the building companies, looking for cost reductions has generated great amout of comparative studies among several constructive systems. Recently the structural walls system is being used also in mid and high level buildings which has as main characteristics, bigger flooring number and layout flexibility. However this characteristics can compromise the structured behavior of the buildings and still increase the production costs. This work presents a comparative analysis among 4 floor buildings under this perspective. Three conceptual blueprints are proposed, on which distinct structural solutions, changing the ratio between the amount of structural and sealing walls are considered: with 100%, 90%, 80% and 75% of structural walls. For these situations, different types of slab solutions are considered: one-way joist slab and flat slab. For each solution the amount of materials calculated and the structural behavior is analyzed, aiming to establish parameters that can represent the influence of the number of structural walls over these factors.

Multilayer systems consisting of magnetic layers of heterostructures can have a variety of magnetic phases - those dependent on factors such as the exchange parameters, the geometry of the material, the temperature T to which it is submitted and the field B applied on it. Let us consider a model of Thin Film in which the various layers that compose it are formed by K Ising plans that have the same coupling constant and which has plans between K / 2 and K / 2 +1 an antiferromagnetic coupling whose interpretation would be physical defects and / or impurities in the material. The system is modeled by the following spin Hamiltonian, where the first two summations represent the interaction of first neighbors in the upper and lower layers and the third represents the interfacial antiferromagnetic coupling and the latter represents the system's interaction with the field B. The calculation of magnetic response of the model allows us to obtain temperatures and their critical fields on phase transitions of the 1st and 2nd orders allowing us to build the phase diagrams of the system. We also obtained the zero field critical exponents related to the magnetic response of the material to verify the Rushbrooke relations. We also made an analysis about the cycles of hysteresis of the material. The Monte Carlo algorithms used are the Entropic Sampling whose main idea is to exploit the principle of maximum entropy, and the usual Importance Sampling algorithm, introduced by Metropolis et al.

The objective of this research was to study the social representations of members of the Family Health Teams over the abuse of alcohol by the elderly. We tried to analyze, understand and interpret the ideas, perceptions and concepts reported by participants that can be mobilized towards this population. The study was to survey the field of health units from the city of Araras (São Paulo, Brazil). In constructing this work, we rely on the participation, as respondents, fifteen members of the Family Health Teams from different backgrounds (nurses, auxiliaries and nursing technicians, community health workers, dentist and doctor). This is a qualitative study, in which methodological approach we used semi-structured interviews, whose contents were analyzed according to pronouncements emerging from the oral testimony, we, therefore, the technique of discourse analysis, included within the scope of the analysis method content. The results were interpreted according to the theory of social representations, grouped in three categories: social representations of aging, alcohol use in general and, finally, the abuse of alcohol by the elderly. The elderly, in general, were portrayed as fragile, with most disease processes, which would be increased with the use of alcohol. This emphasis seems strongly rooted in the biomedical model. The elderly who constitute abuse of alcohol would be a hidden population for the group of respondents, who seem to be considered from the standpoint instrumented semiological and therapeutic for his actions on these patients. These actions end up being, to indicate that statements, based mainly on knowledge of common sense. We identified a positive attitudinal predisposition to attend to the elderly, an element that can also help guide the strategies for continuing professional education relating to elderly care that makes the abuse of alcohol.

The ascension of financialization brought implications on the organizations, because they need to deal with the demands of the financial markets and its shareholders. Parallel to this movement, quality management has been gaining ground in organizations, from different approaches and the latest called Six Sigma. Faced with these two themes, the objective of this dissertation is to investigate the influence of the financial logic in the Six Sigma. To achieve the objective was used Lakatos s Program and a quantitative approach. For this, a exploratory study was conducted based on secondary data, from a documentary research. This research consisted of a detailed investigation of how Six Sigma has been addressed in the events promoted by the International Quality & Productivity Center (IQPC), limiting the analysis of events in Brazil and the United States in the period 2003-2010. Data analysis involved the following steps: examining the profile of the speakers, analysis of the subjects covered in the lectures and analysis of the presentations related to the financial logic. The main results of this study, after analysis and interpretation of information of the documental research, proved the existence of the influence of financial logic in the evolution of Six Sigma in organizations. Among the features of the presence financial logic in Six Sigma, we can mention: seeking opportunities for financial gain in the short term, the possibility of a rapid change of investment to another that is eventually mean higher financial gains, focus on transparency and financial procedures consistency of financial statements of the plans, recognition and reward of the specialists linked to the achievement of high financial goals, the implementation of downsizing strategies, among others.

The fast development of the nanotechnology, and the use of this technology to develop new products to help in diagnosis diseases, drugs and treatments for many diseases is increasing. Some authors have been warning about the nanoparticles use, because the real affect, toxic or not, still unknown. Iron oxide nanoparticles have been used in contrast liquid for magnetic resonance imaging, cancer treatment, among others. The aim of this work was to analyze the possible effects of chronic treatment with these nanoparticles in adults rats. The animals were distributed in 3 groups: Control (saline 0.9% - 0.1 mL/100 of body weight), nFe 0.3 (magnetic iron oxide nanoparticles 0.3 mg/kg BW) and nFe 0.6 (magnetic iron oxide nanoparticles 0.6 mg/kg BW). The animals were treated by gastric gavage during 8 weeks, 5 days per week. The body weight of the animals from the nFe 0.6 group decreased when compared to animals from the control group, and the BW of the animals from nFe 0.3 group was not different from the control group. The animals from the nFe 0.6 group showed the higher blood levels of cholesterol, although the levels of glucose, urea, creatinine, AST, ALT and alkaline phosphatase, plus hematology were not different from the animals of control group. Moreover, the seminal gland and ventral prostate of the animals of nFe 0.6 were atrophied. All those parameters of animals from nFe 0.3 group were not different compared to control group. The bone (femur and vertebra) biometric, biomechanical and biophysical parameters were similar in the animals from the different experimental groups. These results showed that high concentrations of magnetic iron oxide nanoparticles could be toxic and dangerous to the rats when take daily, but in low concentration it could be safe.

In our nearly 40 years of teaching we have observed that many students have mathematics as a great number of rules and formulas that need to be memorized. They do not see any meaning in what they learn either. Few realize the applications of mathematics although they know that they really exist. In an attempt to teach mathematics in a more significant way we decided to conduct an experiment to find out what mathematical knowledge it "hides". The flow of a liquid was the chosen experiment. Analyzing it from a modeling point of view, we intend to find out if there is a mathematical model which can describe it. The functions were obtained from an analysis of initially discrete data and then making the transition to the continuous. Students had the opportunity to construct and interpret graphs associated with related functions, quadratic and polynomial of degree greater than two using Excel. We work with students of the three high school series in a public school. Each class was divided into groups of three or four members. We used the Didactical Engineering as a research methodology.

The plants release primary and secondary metabolites in the environment that may influence the development of adjacent vegetation, this interference phenomenon is called allelopathy. It is recognized as an important ecological process because it interferes with the structure, distribution, composition and dynamics of plant communities. Studies on allelopathic interactions may be useful in the search for natural phytotoxins are produced by plants or microorganisms to be used as natural herbicides, more specific and less harmful to the environment. According to floristic survey conducted by IBGE, Myrtaceae family is one of the major in the cerrado ecosystem. This study attempted to clarify the following issues: species of Myrtaceae family present in the cerrado (Brazilian savanna) exhibit allelopathic potential? There is a similar allelopathic response within genera? Among the active species, which is most promising for starting a bioprospecting? Some of these species has potential as a herbicide for use in agroforestry or organic production of food? To answer these questions were conducted experiments of seed germination and seedling growth of target species cultivated and weedy, and chemical extraction of active compounds in leaves of Myrcia tomentosa. The leaves of Blepharocalyx salicifolius, Campomanesia pubescens, Eugenia bimarginata, Eugenia klotzschiana, Eugenia myrcianthes, Eugenia punicifolia, Myrcia bella, Myrcia lingua, Myrcia multiflora, Myrcia splendens, Myrcia tomentosa, Psidium australe, Psidium cinereum, Psidium laruotteanum and Psidium rufum were collected , cleaned, crushed and stored in plastic bags until use. In the first stage, were carried out the germination and growth bioassays using aqueous extracts of leaf in a concentration of 10% (w / v). We selected three target species, Lactuca sativa and Solanum lycopersicum, both eudicotyledonous and a monocotyledonous Allium cepa. The extracts were applied to all Myrtaceae species compared with the control (distilled water). In the second phase, bioassays were carried out using aqueous extracts of leaves at concentrations of 5 and 10% (w / v). We selected as target species three weeds Euphorbia heterophylla, Echinochloa crus-galli and Ipomoea grandifolia. The leaf extracts of B. salicifolius, M. multiflora, M. splendens and M. tomentosa were compared to negative control (distilled water) and positive (herbicide Oxyfluorfen). In the third stage were carried out biotests germination, growth, and coleoptile of wheat (Triticum aestivum) to direct chemical extraction of active compounds of M. tomentosa. The extractions were carried out using dried leaves powdered and organic solvents of different polarity, the extracts were fractionated using chromatographic column and purified by HPLC. The isolated and purified compounds were identified in RMN13C and RMN1H, by comparison of spectra. The results showed that aqueous extracts of twelve out of fifteen donor species evaluated showed allelopathic activity and each species showed a distinct behavior regarding the allelopathic activity, no grouping by taxonomic proximity. Evaluating the four species most active on weeds species, was detected the potential and efficiency of the extracts, since these were more toxic to weeds species than the herbicide. The leaf extracts of M. tomentosa stood out for demonstrating high activity even at low concentrations, so was chemical extraction from powdered of leaves of M. tomentosa were isolated two compounds from the ethyl acetate extract: juglanin and avicularin, the difference between ix both is the presence of one hydroxyl attached to carbon 3' in avicularin molecule, this difference has an phytotoxic effect more pronounced in the juglanin. This paper is the first report of the presence of the flavonoids kaempferol (juglanin) and quercetin (avicularin) in species of Myrtaceae of cerrado (Brazilian savanna) and gave foundation for future studies on bioprospecting of the M. tomentosa, which did not find any reports of allelopathic studies, fractionation and identification of chemical compounds.

Crabronid wasps of the genus Trypoxylon are characterized by being solitary and nest in preexisting cavities or in mud nests. The species Trypoxylon (Trypargilum) albitarse is included in the latter group, because builds its own mud nests. These nests are made by mud tubes with the lower portion open. Each tube is internally formed by a linear series of cells provisioned with captured spiders in which she oviposits an egg. After that, she starts closing the cell with a mud wall and begins to supply the next cell. Males of these wasps have an unusual behavior among the Hymenoptera. They assist the females during the construction and the provisioning of their nests, besides expelling parasites or other males who eventually approach the nest. This peculiarity of the male guard was always associated with his paternity of female offspring of the guarded nest. However, this hypothesis has not been tested until now, doing this the main objective of this work. The nesting behavior of the species Trypoxylon albitarse was monitored. For this, it took the observation of the nesting pairs and their collecting, as the collect of their offspring. The adults caught were frozen at -20°C for the genetic analysis. The offspring was collected after the construction of the cocoon and, after its emergence, it was weighted and frozen at -20°C for the same purpose. The monitoring of nesting allowed gathering data from this species, adding information to this gender, since most of that is gathered with trap nests. It was seen that that species have more nesting activity in cold and dry seasons, the emergence of adults is mainly concentrated in two moments, before and after the winter. Besides that, most of the larvae spend the winter in a quiescence state. A secondary sex ratio 1:1 was observed in two populations, São Carlos and Araras, however the resource allocation was higher for females, since they are 28% larger than males. To the paternity tests of the guard male, it was necessary to develop a genomic library for Trypoxylon albitarse, which allowed the development of eight microsatellite markers. Four of those were polymorphic and good enough to the purpose of these tests. These genetic tools were the first developed for this gender. They, together with the field observations, allowed assigning the female offspring of a nest to the male who guarded it. However, usurpation and extra-pair copulations were also found, contributing for greater understanding of mating system in this species and the understanding of the functional significance of the male guard behavior. The occurrence of diploid males was detected and their origin discussed.
Remediação de sedimentos eutróficos da Represa Ibirité (MG) pela adição de nitrato e Phoslock : experimentos em laboratório

Ibirité Reservoir (Ibirité/Sarzedo, MG) receives untreated effluents and raw sewage from the city of Ibirité and surroundings, which are the main cause of the eutrophication of this ecosystem. Past studies have shown that sediment is a significant internal source of nutrients (ammonium and orthophosphate ions) to the water column. Within this context, the main objective of this study was to perform laboratory experiments (microcosms) using calcium nitrate and Phoslock as sediment remediation technologies to immobilize orthophosphate ions. Total incubation time was 145 days for the experiments with nitrate and 41 days using Phoslock . The results of the experiments involving the addition of calcium nitrate showed a reduction in the concentration of orthophosphate in the water column (75%) and interstitial water (89%). After 145 days the sediment was significantly oxidized and there was almost complete abatement of acid volatile sulfide in the sediments, leading to a significant increase in sulfate concentrations. The system s nitrogen mass balance revealed the occurrence of an intense process of denitrification. The ecotoxicological assays initially showed that the high concentrations of nitrate (up to 2,300 mg L-1 and 270 mg L-1 in the sediment s interstitial waters, repectively) were responsible for the mortality of test organisms. However, at the end of the experiment, sediment toxicity disappeared completely and there was a significant reduction in the water s EC50 values at 48h. The results of the assays involving the addition of Phoslock showed an 82% reduction in the concentration of orthophosphate in the water column immediately after application of the product and a 64% reduction in interstitial water after 41 days of treatment. The application of the Phoslock suspension increased water column turbidity (150 NTU), which, however, declined by 75% just 6 hours later. The concentration of dissolved oxygen in the water column increased significantly 360 hours into the experiment. The application of Phoslock caused a significant increase in the concentration of dissolved lanthanum in the water column. At the time of application (t = 0), the concentration of La in the water column was 1.64 mg L-1; however, at the end of the assay, the concentration of this element had dropped to less than 0.05 mg L-1. The ecotoxicological tests showed that at t = 0 the application of Phoslock caused mortality of the test organisms in the water column samples, which may have been due to an increase in turbidity and La concentration during this period. Consequently, at the end of these assays, the toxicity was completely eliminated. Considering the general characteristics of the assays performed here, it is postulated that both the technologies studied showed good application potential, i.e., the results obtained indicated that both technologies were efficient in removing P from the water. However, the chances of success of these treatments in the long run will depend (among other factors) on the abatement of the external sources and on the long-term maintenance of such abatement. Since both the technologies investigated appeared to perform similarly in this respect, the use of Phoslock to remediate the eutrophic sediments of the Ibirité reservoir may be more favorable than that of nitrate, if one considers the cost estimates presented in this work from the standpoint of the approximations or forecasts employed here.

The year 2008 was full of "celebration" about the mythical 1968. Universities, newspapers and television networks devoted their attention to the forty-year cycle of major political demonstrations student of brazilian history. Besides remembering the student uprising, we must think what is left of this movement to contemporary politics, as these actors observe and reinterpret their past attitudes. It is clear that the ideals of the former student left is no longer the same. Many of the former militants, who have achieved political power, have their practices related to manifestations of forty years ago. One hypothesis that guides this dissertation is that the time changes the structures and the social and the ways of political scenario depend on a constantly rewritten history. Since the two main political student from 1968 to guarantee excellence of the university and public repudiation of the military regime, it is interesting how these same people act as they are now members of the political elite. Using the methodology of work the tools of 'Oral History' and 'Paths of Life', this research addresses the student struggles of the period, through the oral histories of some of the student leaders of 1968. Throughout the process of democratization, the dominant structures able to absorb important part of proposals for new groups of social movements that have emerged since the 1970s, as the movements of women, homosexuals and ethnic minorities, and also the proposals related to the revolution behavior and culture of the 1960s. In this scenario, the former student activists of the left had to readjust their goals, platforms and agendas as they entered politics through the new parties that formed in the late 1970s. The uniqueness of man is also a way of revealing how people universalized through their lives and their actions, the historical era in which they live, thus revealing hidden pathways still a movement that was also trainer of the contemporary political scene.

The poor financial performance of some quality award winners in different countries arises the interest of researchers to investigate why that happened. The majority of this kind of investigations was carried out in United States and Western Europe. The most common performance measures were growth, profitability, market value, and customer satisfaction. In Brazil, there are few studies on this issue. This master thesis aims to analyze the value creation by National Brazilian Quality Award winners using Economic Value Added (EVA ) as the performance measure and comparing those values with competitors from the same economic sector. The application of EVA as performance measurement is a differential from other studies. The Brazilian database Economatica, financial websites, and companies websites were the main source of data. The data acquirement covered a period of time of ten (2000-2009). The parametric tests were applied to test the hypothesis. The main finding shows that the winner companies have increased the value creation to the shareholders after the awarding of National Brazilian Quality Award. Another main finding points out that the winner companies have increased the value creation in average to the shareholders more than the companies from the same economic sector after the awarding of National Brazilian Quality Award. It is important to highlight that before the awarding the studied companies were not creating more value to shareholders than the companies from the same economic sector.

Automatic text summarization has been of great interest in Natural Language Processing due to the need of processing a huge amount of information in short time, which is usually delivered through distinct media. Thus, large-scale methods are of utmost importance for synthesizing and making access to information simpler. They aim at preserving relevant content of the sources with little or no human intervention. Building upon the extractive summarizer SuPor and focusing on texts in Portuguese, this MsC work aimed at exploring varied features for automatic summarization. Computational methods especially driven towards textual statistics, graphs and machine learning have been explored. A meaningful extension of the SuPor system has resulted from applying such methods and new summarization models have thus been delineated. These are based either on each of the three methodologies in isolation, or are hybrid. In this dissertation, they are generically named after the original SuPor as SuPor-2. All of them have been assessed by comparing them with each other or with other, well-known, automatic summarizers for texts in Portuguese. The intrinsic evaluation tasks have been carried out entirely automatically, aiming at the informativeness of the outputs, i.e., the automatic extracts. They have also been compared with other well-known automatic summarizers for Portuguese. SuPor-2 results show a meaningful improvement of some SuPor-2 variations. The most promising models may thus be made available in the future, for generic use. They may also be embedded as tools for varied Natural Language Processing purposes. They may even be useful for other related tasks, such as linguistic studies. Portability to other languages is possible by replacing the resources that are language-dependent, namely, lexicons, part-of-speech taggers and stop words lists. Models that are supervised have been so far trained on news corpora. In spite of that, training for other genres may be carried out by interested users using the very same interfaces supplied by the systems.

When studying the literature in the area of teaching and learning languages, two multifaceted and meaningful concepts can be identified, they are authenticity (GILMORE, 2007) and motivation (DÖRNYEI, 2001; VIANA, 1990). Concerning the integration of both themes, Gilmore (2007) points out that, although there is common belief about the motivating potential of authentic materials, there is little empirical support for stating the existence of this relationship. This research investigates which relations may be established between authenticity and motivation through the development of activities that focus on the genre newspaper report in the English language classrooms for learners who participate in an extension program at a Federal University in Sao Paulo State. The choice of this genre as a combination of both theories was made based on its relevance in the New Curriculum Proposals for the State of São Paulo and also due to the lack of studies that guide the pedagogical practice in the development of meaningful activities through genre. (OLIVEIRA, 2010). Therefore, based on the data analysis and the conclusion of this study, it is possible to verify how through the genre newspaper reports it is possible to integrate authenticity and motivation, reflecting on students-participants‘ behavior, their written productions and in the teaching and learning of languages.

O universo atual da informação, da comunicação e da educação, tem se reconfigurado cada vez mais a partir de sua vinculação às tecnologias computacionais. Em um movimento sincrônico, se convergem a produção do conhecimento, as demandas de informação e os aparatos tecnológicos. Sobre estes, pre-senciamos o alucinante desenvolvimento e aperfeiçoamento de dispositivos móveis, que armazenam e tornam acessível, a qualquer momento, a informação. Neste mesmo momento, temos tido uma reconfi-guração dos espaços físicos de pesquisa e acesso ao conhecimento, como o caso de Bibliotecas Públicas e Universitárias (Information Commons - IC). Estes espaços tem se remodelado arquitetonicamente para flexibilizar e otimizar uma interação de qualidade entre usuários, tecnologia e conhecimento. Neste contexto, o presente artigo pretende sinalizar os conceitos e as iniciativas que prerrogam a articulação dos saberes tradicionalmente articulados no âmbito das Bibliotecas, que são mediados agora também por celulares, iPads, Smartphones - M-libraries, e ainda, caracterizar os espaços IC, como uma tendên-cia para Bibliotecas pragmáticas e interativas contemporâneas. A partir disto procura-se discutir o re-posicionamento dos profissionais da informação diante do cenário atual de mobilidade da informação.

The occupational therapist activity seeks to promote autonomy and independence for the general population in the different areas of personal and social interaction, participating in the development of social policies. Among the intervention strategies is the use of accessibility resources and technologies to enhance human functionality. The profession strives to guarantee peoples rights regardless of special needs, whether temporary or permanent. Professional legislation entitles the occupational therapist to the use of assistive technology in daily activities and in instrumental daily life activities. This research s objective was to analyze occupational therapist education in order to work with accessibility resources and assistive technology. It considered seventeen Brazilian bachelor courses, nine of which private, four federal, and four state schools, as well as forty junior and senior students. Data collection techniques included documental analysis and surveys. According to the used method, in the first step theoretical and practical subjects from the curriculum were considered. The second step used surveys to assess students perception of their own capability in the areas of accessibility and assistive technology. The results showed an overall average of 71,96 hours dedicated to assistive technology, representing 2,25% of the minimum required time, concentrated in subjects with minimum required times varying between 59 and 89 hours. The documental analysis results showed that these contents are presented in specific required subjects (82,4%) and in non-specific required subjects, where they are part of the curriculum (64,7%). A disparity between this research s findings and the students perception was observed. Students state that 42,5% of the contents were offered in specific subjects and in the subjects referred to as Applied . Some of the main results indicate that there is no identifiable systematization of contents and time spent and that the contents are treated superficially. Furthermore, they show that the students feel more prepared to evaluate than to use technological resources and do not feel ready to create and develop accessibility resources and assistive technology. The results obtained in this research can contribute to improve and better direct the course content in light of the development of accessibility resources and technologies within the parameters of inclusion and in doing so, to better qualify future professionals.

The increase in the number of elderly in the population and increased longevity create greater opportunities for interaction with children of this overall population. Since the beginning of life children develop attitudes toward aging and older people with whom they live. The perception that progressively build is based on these relationships and are influenced by several factors. Objectived to assess the attitude toward aging of children living with elderly people with and without cognitive impairment and check on the perception of the same dementia / Alzheimer disease (AD). The study was based on the method of quantitative and qualitative research and ethical guidelines were followed. Was interviewed 54 children from 7 to 10 years of age were enrolled in five different Units of Family Health of a city of State of São Paulo who were living with at least one elderly person. The children were interviewed, was applied a questionnaire of characterization, Scale of Attitudes Toward Aging for Children and issues related to aging and dementia / AD. In the elderly living with children (n = 46) was made the characterization and applied the Mini-Mental State Examination (MMSE). Quantitative data were statistically analyzed and the qualitatives by thematic analysis. Most children were male, had nine years, was in 4° grade of Elementary School and was the granddaughter of the elderly with whom she lived. The average of child in the attitude scale was 1.59 points, one point represents the most positive attitude possible and three points more negative. The elderly were mostly female, between 60 and 64 years and mean MMSE score of 20.4 points. Most children (53.7%) live with elderly people without cognitive impairment. Significant differences was found in the areas of cognition and social relationship of the attitude scale when was compared groups of children living with elderly people with and without cognitive impairment, being that those who live with elderly with cognitive impairment have more negative attitudes in these areas. Regarding the open issues, changes in physical appearance and way of thinking have been highlighted as inherent to aging. They also emphasized the memory loss of elderly patients with whom the child lives. The vast majority of children had no knowledge about dementia/AD. Health professionals in basic attention should be attentive to multigenerational families, and within the Family Health Program to invest in strategies for gerontological education.

PART I: Polymeric nanoparticles and bioassay-guided phytochemical investigation of Trichilia elegans e Trichilia catigua (Meliaceae) for the control of leaf-cutting ants Leaf-cutting ants are known as severe agricultural pests. Several compounds have been proposed for their control such as organophosphorus, pyrethroids and sulfluramid insecticides. However, non-target animals and environmental contamination are common problems and therefore new strategies to control these pests have been requested. In this context, this work involved the bioassay-guided study of T. elegans e T. catigua (Meliaceae) and also the development and characterization of three different nanoparticles, containing either ricinine, xanthyletin or rauianin for the control of leaf-cutting ants. Phytochemical investigations from active extracts and fractions have allowed to isolate 23 compounds (3 new), including sterols, coumarins, phenolic compounds, oxazol derivative, flavonoids and limonoids. The compound 3-(4'-hydroxyphenyl)-2-propenoic acid (4''-carboxyl)-phenyl ester (14), from T. elegans, showed high biologic activity against leaf-cutting ants. Additionally, the limonoid cedrelone, from T. catigua, was active against the symbiotic fungus of leaf-cutting ants (L. Leucoagaricus gongylophorus). The solvent displacement technique adopted here showed to be very efficient for the preparation of nanoparticle formulations containing either xanthyletin or rauianin. In addition, a novel method was developed for the encapsulation of ricinine. These natural insecticides were nanoencapsulated for the first time and the results observed here showed a better activity, more water dispersivity and stabilization of nanoparticles if compared to free compounds.
