This dissertation presents a proposed methodology for monitoring corporate mortality, and some results of its use to evaluate the mortality of technology-based companies in São Carlos, SP. The proposed methodology comprises 12 steps, and provides guidelines for defining the criteria for characterization of mortality (Stage I), selection of sources of information (Stages II and III), choice of the period of observation (Stage V), construction of the universe of research (Stages VII and VIII), determining rates of mortality (Stage XI), and identification of causes of death (Stage XII). The methodology also guides actions for routine monitoring of corporate mortality, and to compare results. The methodology was applied to evaluate the mortality of technology-based companies in São Carlos. The universe of the research was formed by the companies created by the year 2005, organized in four entries, namely ParqTec, GETEC, PIPE, and São Carlos. The criterion used for mortality was the formal closure, as detected in the JUCESP (Board of Trade of São Paulo State), and Internal Revenue Service taxpayer number (CNPJ). The period of observation of mortality ranged between 2006 and 2010. The following mortality rates were obtained: 5.2% of the companies from ParqTec established by 2005 formally ended their activities from 2006 to 2010. Similarly, the mortality was 6.8% of GETEC register, PIPE 0% and the rate of São Carlos register was 5.6%. The causes of death were explored by consulting the leaders of the companies closed. Due to the small number of responses, 8 questionnaires, the results regarding causes of death should not be regarded as conclusive. The methodology contributes primarily to guide the process of designing and implementing research to evaluate business mortality, to guide the choice of methodological alternatives, and comparing results.

The thesis will address a modern view of electrochemistry for the discharge and charge reactions of Lead Acid Batteries study. Even though these batteries have existed for more than 200 years, electrochemical mechanisms are still not fully understood. Recently, there is a discussion in Brazil about the need to improve energy accumulation processes that have not kept pace with the development of technologies such as electric car engines, telephony devices, computers. The production of lead-acid batteries is the only Brazilian energy accumulator. These Batteries continue to grow worldwide, increasing their forms of use, leaving the current car starter batteries and stationary stabilizers for hybrid cars (micro and medium hybrid), electric motorcycles, electric trains, mobile phone towers, oil platforms, among others. In this thesis, we started a critical review of the published data bibliography and its meanings. Most of the published work proposes that the mechanisms of unloading and loading the plates are by dissolving precipitation and would be similar. However, studies with negative and positive flat electrodes show almost no dissolution during these electrochemical reactions. Thus, the precipitation dissolution mechanism would not be justified. In the last decades, several studies already indicate that these mechanisms can be understood as solid-state mechanisms by adding the partial disruption phenomenon, which we will explore in this thesis. The literature data shows differences between the negative and positive plates mechanisms that need modern treatments because their discharge products are different films and from nanometer order. Finally, electrochemical and analytical studies will be carried out, with positive and negative flat electrodes. Experimental methods for negative flat electrodes are treated in detail, while positive flat electrodes still have a lot to be developed.

Culturally, care delivered to elderly individuals in Brazil is usually provided by families. Even though only 1% of the Brazilian population older than 60 years of age is cared for in long stay institutions, the search for this type of facility has increased, mainly due to population aging and new family arrangements. This study analyzes the relation between family functionality and the variables of age, gender, duration of institutionalization, family composition, depressive symptoms and cognitive changes in elderly individuals residing in long stay facilities in a city in the interior of São Paulo, SP, Brazil. This is a quantitative cross- sectional study with a descriptive correlational design. A total of 107 elderly individuals were individually interviewed using the following: Family APGAR, Mini State Mental Exam, Katz Index, Pfeffer Functional Activities Questionnaire and Geriatric Depression Scale. Outcomes were analyzed by logistic regression analysis using the hierarchical analysis using the Stepwise technique. This study complied with all ethical aspects. In relation to socio-demographic characteristics, the institutionalized elderly individuals were mostly older elderly women (61%), (45%)with a low education level, (87%) Catholic and (45%) widowed. Most independently performed basic daily living activities (46%), but were dependent for instrumental activities of daily living, had depressive symptoms (67%) and cognitive impairment (53%). The results show that 57% of the elderly individuals had a high level of family dysfunction, 22% had good family functionality and 21% moderate family dysfunction. No statistically significant association was found between the family APGAR and the variables gender and age. Elderly individuals with families composed of more distant relatives such as siblings, nephews and nieces, with greater time of institutionalization, depressive symptoms and cognitive impairment were also more dysfunctional. The institutionalization of elderly with time over 3 years (OR = 3.861, p = 0.0285), presence of depressive symptoms (OR = 5.378, p = 0.0044) and family composition formed by brothers / Nephews / Other (OR = 6.812, p = 0.0155) are more likely to experience family dysfunction. These findings can contribute to planning for care delivered to the family of institutionalized families.

This study investigated the role of H1 amygdala receptors in state-dependent memory deficits induced by L-histidine (LH).To address this question, we investigated the effects of H1 antagonist chlorpheniramine (CPA) microinjected into the amygdala on anxiety and emotional memory retrieval in mice submitted to the EPM. Experimental subjects were 117 adult male Swiss mice weighing 25-32g at testing. Tests using an elevated plus-maze (EPM) were performed on two consecutive days: Trial 1 (T1) and Trial 2 (T2). Before each trial, mice were intraperitoneally (IP) injected with LH (500mg/kg), a histaminergic precursor. Two hours later, they were microinjected with chlorpheniramine (CPA; 0.016, 0.052, or 0.16 nmol/ 0.1 μl), or saline (SAL) into the amygdala, and five minutes later reexposed to the EPM. For each CPA dose administered, the animals were randomly assigned to four groups based on drug treatment: control (i.p injection and i.a SAL), LH-SAL (i.p injection LH and i.a SAL), SAL-CPA (i.p injection SAL and i.a CPA) and LH-CPA (i.p injection of LH and i.a CPA). The data were analyzed using two-way analysis of variance (ANOVA) and Fisher LSD tests. IP injection of LH and microinjection of CPA into the amygdala did not induce significant T1 differences between groups for percentages of open arm entries (%OAE) or open arm time (%OAT) (ANOVA, p > 0.05), which indicated that the drugs did not affect anxiety. In T2, the control group and the groups that received IP injection of SAL and an 0.016- or 0.052-mnol infusion of CPA (SAL-CPA) demonstrated significant reductions in open arm exploration (%OAE and %OAT) (p < 0.05), suggesting a retrieval of aversive information concerning the open arms. Importantly, the LH groups that received an injection of SAL (LH-SAL) or CPA (LH-CPA) did not exhibit decreased open arm activity; no significant differences in %OAE and %OAT (p > 0.05) were observed between T1 and T2, suggesting that the LH-induced deficit in emotional memory retrieval was not reversed by CPA injection. Furthermore, animals that received IP injections of SAL and 0.16 nmol infusion of CPA (SAL-CPA) did not exhibit decreased open arm exploration in T2 compared to T1 (p > 0.05). No significant changes were observed in the number of enclosed arm entries (EAE), an EPM index of general exploratory activity. Taken together, these results suggest that the H1 receptors in the amygdala are not implicated in anxiety-like behaviors but are involved in emotional memory deficits induced by the T1/T2 EPM protocol in mice.

Studies on the electrodeposition of semiconductor films has been developed primarily for the binary chalcogenides. However, there are several ternary systems that are poorly researched and have broad application spectrum, for example, the CdZnTe. In this sense, the objective of this work is to study the electrodeposition process of thin films of CdZnTe semiconductors and evaluate their optical properties, composition and morphology. In this work were used as substrates ITO and Pt electrodes, and CdSO4, ZnSO4, TeO2 solutions in the presence at different support electrolytes (C4H4O6KNa, acetate buffer (pH4) and (NH4)2SO4). The influence of supporting electrolyte in the electrodeposition process and films morphology was also evaluated. It was observed that the most suitable deposition media was sodium and potassium tartrate, because the films were more homogeneous. In this media was studied the influence of bath composition on the morphology, composition and band gap of the films. The films were grown at -1,2 V for 1h. Images obtained by FEG (field-emission scanning electron microscopy) revealed uniform films, and grain refinement was observed for coating deposited on ITO substrate. The films on ITO were analyzed by UV-vis to determine the band gap values, which varied from 1.5 to 1.7 eV, depending on the film composition. The deposition was also performed by multiple pulsed-potentials technique. The deposition potentials, based on the voltammograms, were -0.2, -0.9 and -1.2 V for Te, Cd and Zn, respectively. In these experiments the substrate was Pt and different deposition times were employee for each potential, maintaining a total time of 30 min. The morphology indicated Cd-rich clusters and Te-rich smooth regions, according to the EDX (Energy Dispersive X-ray) data. In order to promote a major change in the composition of ternary films, new deposition conditions were used, in which the elements quantities of the films were adjusted by changing the time on each applied potential and ions concentration. In this case the band gap values were around 1.8 eV, an intermediate value between the band gap of two binary semiconductors, CdTe and ZnTe. The analysis carried out by XRD (Diffraction X-rays) was also an indicative of ternary phase s presence, such as, cubic, tetrahedral and hexahedron. By the proposed methodology, was possible to obtain CdZnTe films with ternaries phases and control its grain size, optical properties and composition. Therefore, the main objective of this study was achieved, since it was possible to obtain films with different stoichiometry and thereby change its properties. The electrodeposits showed optical properties comparable with those of films obtained by physical techniques. Thus, the use of a technique relatively simple and low cost could easily be adjusted to produce these materials on a large scale and allow its use in photovoltaic systems, for example.

Abstract The asymmetric distributions has experienced great development in recent times. They are used in modeling financial data, medical, genetics and other applications. Among these distributions, the Skew normal (Azzalini, 1985) has received more attention from researchers (Genton et al., (2001), Gupta et al., (2004) and Arellano-Valle et al., (2005)). We present a comparative study of _-stable distributions, Skew normal, Skew t de Student and Skew Laplace. The _-stable distribution is studied by Nolan (2009) and proposed by Gonzalez et al., (2009) in the context of genetic data. For some real datasets, in areas such as financial, genetics and commodities, we test which distribution best fits the data. We compare these distributions using the model selection criteria AIC and BIC.

This study has as an objective to examine the consequences of higher education amendments and the institutional transformations it has been suffering in this scenery. It was collected data from four institutions that act in the state of São Paulo, from which two are confessional universities with a historical presence on this sector and the other two are from the business segment that came from the educational amendments and have expanded from it. It has been used the concepts of substantive rationality and formal rationality of economic ends from Max Weber in order to analyze the researched data from the universities, gathered as the following: the concept of university and the academic, management, the economic-financier concept and its relation with society. The confessional universities have became after the amendments, an alternative in crisis, in which the challenge is, from one side, to survive without surrender to the market s logic and keep its identity with no disguises, and on the other side, being acknowledged as such by public policies, in a way of assuring the conditions to act in the search of quality and relevance of Brazilian s superior education.

The present study aims to identify determinants of the decision of beef cattle farmers on whether or not to demand rural credit. The specific purposes are: i) identify barriers to the rural credit demand by beef cattle farmers in the state of Sao Paulo; ii) identify determinants of adoption of different rural credit contracts by beef cattle farmers and; iii) identify determinants of the volume of rural credit used by beef cattle farmers. The sample comprises data on 86 livestock farmers in 10 regions of São Paulo State. The empirical analysis of the survey data is performed with the estimation of a logit model and with descriptive statistics. The theoretical framework used was the New Institutional Economics applied to the context of rural credit markets, with main focus on screening, monitoring and enforcement problems of rural credit contracts. The results show that all farmers who demanded credit in 2010 had access to it. However, the bureaucracy (which increases transaction costs) inherent in the process of obtaining credit and the fear of losing the collateral has been identified as mechanisms of selfselection and therefore self-exclusion from the process of farmers demand for rural credit. In the logit model results was found that farmers who adopted capital intensive production systems, have off-farm income, have more than one farm, are younger and are affiliated to producers association linked to livestock are more likely to demand rural credit. Some of these variables, such as greater number of farms and income from off-farm activities may present distortions in rural credit policy for beef cattle in São Paulo. Resources under special conditions from the governmental rural credit program may be coming at the hands of farmers who least need these resources. To identify the determinants of the expansion of access and use of rural credit by farmers were also used a logit model. The results showed that farmers who adopted capital intensive production systems, have more farms, are older and adopt risk management mechanisms are more likely to use two or more rural credit contracts. These farmers have adopted different strategies to overcome the volume limits of governmental rural credit, which were presented in the study. We concluded that the relaxation of requirements for obtaining rural credit is not the best mechanism to increase demand and use of rural credit by beef cattle farmers. On the contrary, the relaxation of conditions of access to rural credit can make the results of the rural credit policy disastrous in terms of default and financial sustainability. Last but not least, some suggestions were presented for beef cattle rural credit policy in the State of São Paulo. These suggestions are grounded in the results of econometric models presented here and go beyond the rural credit market itself.

Among the current media forms, the alternate reality games (ARG) is in the spotlights due its capability of giving a ludic experience with strong immersive qualities. Setting its fictional world in sync with everyday reality, the ARG seeks to smear the border between fiction and non-fiction, in order to intensify the experience of the audience. This research analyzes the immersion strategies of alternate reality games based on the study of The Lost Experience (LTE), with the purpose of understanding how the immersion process on the fictional world created by ARGS occurs. Therefore, the main characteristics of alternate reality games are studied, from its main principles established in order to make accessible the fictional world connected to the everyday life of the players, trough the interface of the media. In this process, the concept of immersion is problematized, in order to understand the extension this term receives in front of some perspectives that denote its nature. Visions that lead to a common denominator that connects the notion of immersion with the pleasure of being involved in a sensorial, cognitive and emotional degree towards external stimuli, that as an answer leads an action over the experienced environment. The analysis of the immersion strategies in The Lost Experience helps in the comprehension of how it sets up its fictional world in touch with everyday life, with the goal of creating immersive zones that allows the interaction of players with the elements of its universe.

Women are the majority of the Brazilian population and the main users of SUS -Unified Health System. The climacteric is defined as a biological stage of life and not as a pathological process, and comprises the transition between the reproductive and the non-productive period of women s life. It corresponds to the decline of the ovarian function and is characterized by a progressive state of hypoestrogenism, to which a set of multi-organic manifestations affecting women`s health and life in short, medium or long term, is related. The climacteric symptoms involve nocturnal sweating, hot flushes, insomnia, musculoskeletal pain, vaginal dryness, osteoporosis, increase of cardiovascular diseases, emotional lability, irritability, jitters, and depression. In addition to the physical and biological alterations, the socio, economic, and cultural context plays a fundamental role in this transition stage. The average menopausal age is around 51 years, with the gradual increase of the average life expectation reaching 77 years, Brazilian women will live one third of their lives in post-menopause. Currently, about 32% of Brazilian women are in the climacteric stage. The primary attention is the adequate level of attention to meet most of the health needs of climacteric women. In face of, the first study was aimed at investigating the prevalence of musculoskeletal pain in climacteric women registered in a Mixed Unity of Health in a low income community in the south of the city of São Paulo. From women participating, 93.55% complained of musculoskeletal pains, and the average of pain in the analogical visual scale is 6.88 (±3.03). Pain is also an element sub-notified by the primary care in Brazil, as they are not specifically registered in the Basic Health Unit. Primary care is responsible to conduct proactive actions in face of the health-disease problems of the population, and to develop activities based on the situational diagnosis. This high rate of pain evidences the needs of women in this stage and the subsequent planning of activities purposed to meet such needs. Taking into account this result, the second study was conducted. The objectives were (1) evaluate the quality of life; (2) evaluate the presence and intensity of climacteric manifestations; (3) evaluate the presence of depressive symptoms in this population. The quality of life of these women had a strong negative impact, especially on the physical component domain. The psychological symptoms were the most prevalent manifestations. With an average of 7.29 (±4,26) in the Menopause Rating Scale, depression was significantly related with the decreased quality of life and the increased symptoms regarding this stage. Although it`s difficult to say that such symptoms are exclusively related to the climacteric, this study provides a situational diagnosis of a population of economically active women living a critical period for the occurrence of musculoskeletal pains, negative impact on the quality of life, and depression. The early detection of symptoms in primary care will determine efficient preventive actions and therapeutic strategies. The use of specific instruments to evaluate the individual complaints helps diagnosing the actual needs, thus producing a more accurate epidemiological survey and a better multidisciplinary clinical management.

The Brazilian State, in order to start a new political relationship with indigenous communities, implemented, in 1999, the National Policy of Attention to Indigenous Health (PNASPI), through the National Health Foundation (FUNASA) and 34 Special Indigenous Sanitary Districts (DSEIs) located in the national territory. The new health policy for the indigenous areas, structured within the differentiated attention Subsystem and integrated into the Unified Health System (SUS), proposed a participatory model of Civil Society-State comanagement, via council or public policy managers, cooperation agreements with NGOs and other participatory experiences. Just likeit probably occurred in other indigenous territories, the implementation of a new State Agency in the Xingu brought a creative process of political and cultural adaptationto local leaders, generating the possibility of an inter-ethnic negotiation field. It was therefore from this political scenario that the research proposed to understand the indigenous leaders' forms of practice and their representations. Thus, it sought to observe the strategies of the region s representatives who "make pacts" and "negotiate" with the various organizations responsible for the implementation of health public policies (FUNASA, City Halls and NGOs), oriented by constitutional principles that ensure (universal) rights and (differentiated) specificities regarding preventive health care to these and all other indigenous groups within the national territory. The analysis of these forms of organization and political activity also sought to observe how the implementation of the health policy and its institutional arrangements generated a redesigning of the policy practices established between indigenous peoples and the State. Thus, even though indigenous leaders have not articulated a homogeneous position regarding the State's "offer" of partnership through NGOs and management councils,many of which with goals to ensure recognition and political spaces both in the national scene and in their traditional systems of organization, they started a project that pursues the enlargement of the memberships and a change in the organizational structure of the State.The movement, conducted by the leaders of the Alto Xingu, involves a participatory model of comanagement, whose practice does not dispense a few moments of consummation of the identity among the actors who make up this participatory experience.

ABSTRACT Supply chains are becoming increasingly important for companies to survive in today's competitive market. Theories and methods that contributing to the improvement of its management are important elements for research and development in the field of Industrial Engineering. Considering the performance measurement systems as one of these elements, this thesis aims to propose an adequacy model of performance measurement systems and its maturity to the maturity levels of supply chain management due to the lack of a study that shows the relationship between these two elements. For this were studied the performance measurement systems and its maturity as well as the maturity models for supply chain management enabling to build a theoretical model of relationship between these two elements. Using the multiple case method applied on three different analyze units it was possible to analyze the theoretical model purposed. As the main results of this research, in most of cases, was identified the existence of a relationship between the maturity of performance measurement system and maturity of supply chain management, although not always all elements of maturity of these two elements are in the same level of development. As contribution, this model aims to present a new approach to the theory of the performance measurement systems in the supply chain management, as well as, to provide to the practitioners the correct alignment between the maturity of supply chain management and maturity of performance measurement systems.

The first registrated public health campaigns in Brazil occurred in the 19th century, when the government created the royal press. In the beginning of 20th century, Oswaldo Cruz s sanitarism s initiatives focused in health campaigns. This approach culminated, sometimes, in insurrection and manifestations. In 1925, the concept of health education brought new perspectives to public approach, intending to change individual behaviors in order to guarantee a healthier life. Later, the concept of health promotion, overcame it, going beyond the goals of providing information and changing behavior: the objective is law proposals and other mechanisms to help people. The history of Brazilian health campaigns is full of faults and skills. A lot of papers have already reviewed these campaigns, but no one investigated the virtual environment provided by the internet in the Brazilian context. The main goal of this research is to investigate how online health campaigns talks to the public, according to the scientific models of communication and to the concepts of health education and health promotion. This paper studies the online campaigns of health alimentation, vaccination and medicines indexed on the Portal da Saúde Brazilian Health Ministry s website. Health education is prevalent in campaigns approach, as the contextual and cognitive deficit models. We conclude that there are a lot of available resources to improve the dialogue to the public, but the online campaigns use communication models to frame medical or scientific authority, providing information and behavior changes. Key-words: health campaigns, online campaigns, models of scientific communication, health education and promotion. ...

In this work we present a Bayesian analysis for bivariate survival data in the presence of a covariate and censored observations. We propose a bivariate distribution for the bivariate survival times based on the Farlie-Gumbel-Morgenstern (FGM) copula to model data with weak dependence. Some survival models with and without cure rate have been assumed for the marginal distributions. For inferential purpose a Bayesian approach via Markov Chain Monte Carlo (MCMC) was considered. Further, some discussions on model selection criteria are given and comparisons with other copula models were performed. To detect influential observations in the data we consider a Bayesian case deletion influence diagnostics based on the -divergence. The OpenBUGS and R systems were used to simulate samples of the posterior distribution. Numerical illustrations are presented considering artificial and real data sets.

Zirconia has been widely applied on production of structural components, mainly due to its great mechanical properties. However, these properties are associated to the zirconia tetragonal and cubic phases, which are stable only on high temperatures on pure material, being necessary doping the material with some oxides to keep these phases at ambient temperature, on a metastable condition. The industrial production of pieces on zirconia is a function of economical and operational aspects, being more common than chemical methods using the mechanical mixture process for adding the stabilizer oxides to the zirconia powder. On this context, the present work was done in association with an industry of marketing and manufacturing of technical ceramics components, among which stands out the products made on magnesia-partially stabilized zirconia (Mg-PSZ). The aim of this work was the identification of the main aspects associated to the industrial process for the production of zirconia Mg-PSZ that determine the final characteristics of the components, beginning with the characterization of the products of each production stage and the conformation of test bodies for the confirmation of the material stabilization after the sintering process. Thus, it was investigated the production of two batches of powder made from mixing the raw materials by a wet process followed by spray-drying, altering the pH of one slurry, by the addition of an aqueous solution of hydrocholoric acid. It was observed, on the end of the characterization process, that the slurry with reduced pH presented a differential behavior during the spray-drying process, which were responsible for the better mechanical properties on the sintered bodies made from this batch of powder. The analysis of the characterization results allowed the definition of the processing parameters that require a special control to the warranty of final products made on Mg-PSZ, according to the literature review done.

Master's Thesis. Education Graduate Programme of Universidade Federal de São Carlos. São Carlos, 2012. This Master's thesis deals with the scientific investigation of a process of musical education among the elderly and children, and aims to draw a reflection on some of the cultural changes of recent decades, from acquaintanceship dialogued with a group of women in the aging process, in a educational institution located in a country town in the state of Sao Paulo. The social practices investigated work with the collective musical memory as an instrument for reflection, awareness and appreciation of identity, and seek to develop a method of interaction among generations that respects the cultural imaginary of cultural agents involved in the research. This intervention makes use of music as expressive language of values and habits of the Brazilian people, and highlights the Musical Education as a process of social construction potentially humanizing, which must occur through critical and creative educational praxis. It believes that the Brazilian educational processes not only occur in the formal institutions of education, but firstly on cultural and artistic relations of the popular imagination, the oral transmission of values, among different generations. In a process of looking and collectively share knowledge on the "Roda da Vida" (Circle of Life), this research aims to understand the educational processes initiated by intergenerational experiences and reflect about different perceptions and world views of this group of collaborators women through systematization and analysis the circle of conversation and textual and audiovisual records. The process of dialogic analysis of content and organization of results, looking for alternative solutions methodological dialog among research and intervention, and hope to contribute with other studies of intercultural relations at school.

The current state of fragmentation of remaining natural vegetation in São Paulo generates the need for urgent action for conservation. The prioritization of areas is the first step toward developing strategies for biodiversity conservation because it allows the targeting of efforts and resources to subsidize the maintenance and development of public policies on land use. In this sense, this study aimed to diagnose the distribution of fragments of natural vegetation in the municipality of Sorocaba / SP and identify priority areas for conservation through the use of landscape metrics in order to support the creation of protected areas (PA). The remnants of natural vegetation s map was elaborate (1:2.000) through vectorization screen using aerial photographs with scale 1:20.000 of 2006. The maps of hydrography and contour lines were used in the preparation of the Permanent Preservation Areas map (PPA). The following metrics were used for the map of priority areas for conservation: Area (hectares) PROX (connectivity between fragments) and SHAPE (relationship between perimeter and area). The metrics were valued and assigned to a weight to each of them. The results showed a high degree of habitat fragmentation, with only 16.68% of municipal land with forest cover and 62% of fragments smaller than 1ha, and the largest fragment showing approximately 300 ha. 19% of the territory is PPA, and this area has only 45% forest cover (50% of the total forest cover of the municipality). The restoration of all PPA represents an increase of 11% of forest cover in the entire territory, from 16,68% to 28% and also the appearance of fragments larger than 3.000 ha. The areas with the highest priority for conservation are located in the southeast region of the municipality, where most of rural areas still exist. Another high priority area appeared on the waterfront Pirajibú. Except of the public area called Mario Covas Park, the other fragments with very high priority areas are on private properties, which should lead to an incentive for the creation of PRNP and AMPA. The present situation of the scarcity of forest remnants of the city generates a demand for immediate action for conservation and ecological restoration. The strategies should involve stopping and possibly reversing the process of degradation of natural ecosystems. Thus, the municipality must ensure the preservation of forest remnants through public or private PA, and must implement an ecological restoration program involving various stakeholders such as schools, industries, NGOs and other sectors. Whereas the expansion of the city is an ongoing process, territorial planning should be done to reconcile the demands for infrastructure with the conservation of forest remnants. Plans for urban and industrial expansion should be integrated into the plans of conservation and restoration of natural areas, as provided in Municipal Environmental Policy.

This study seeks to verify the influence of windows areas in the electrical energy consumption of dwellings in the city of São Carlos. In order to do this, the index WWR (window to wall ratio) was applied, representing the ratio of window area and the area of external surface (wall). The applied methodology consisted on field campaigns, modeling and computational simulation. First, taking into account a preexistent data basis, the characteristics of the electrical energy consumption for the whole area of the city of São Carlos was verified. Then, specific buildings were selected to be measured in loco. The field data allowed the determination of building parameters (orientation, volume and constructed area, area of façades and window areas), which were directly or indirectly used as data entry for modeling the electrical energy consumption of the dwellings set. The modeling process applied Artificial Neural Networks (ANN), which is a computational technique inspired on the structure of human neurons. Several models were developed and their performance was evaluated by the determination coefficient (R2) and relative errors, shown by the relationship between simulated and real data. The best model was selected to be applied in the simulation of the influence of WWR and electrical energy consumption. The results showed that the WWR index has influence on the residential consumption of the dwellings studied and that NE orientation causes the lowest impact on electrical energy consumption. Furthermore, an ideal range of WWR/volume between 0,06 and 0,07 is related to the lowest energy consumption per constructed area in the city of São Carlos.

This dissertation has as an objective to present the results of the research conducted for the Master Course of Agroecology and Rural Development of the Federal University of São Carlos. This study aimed to analyze the different existing processes of commercialization in the Rio Grande Do Sul in relation to the concept of organization of its producers and the forms of commercialization used. To develop the present work, a case study will be used, having as object two experiences in the Rio Grande Do Sul. The chosen experiences was the Association Ecologists Farmers Ipê and Antonio Prado (Ipê and Antonio Prado/RS) and the Center of Support Small Farmers (Santa Cruz do Sul/RS). It was conducted a socioeconomic analysis of these experiences, observing how its forms of organization and commercialization influences in the reached results.
