This Masters Degree dissertation seeks to make a comparative study of internal air temperature data, simulated through the thermal computer application DesignBuilder 1.2, and data registered in loco through HOBO® Temp Data Logger, in a Social Housing Prototype (HIS), located at the Central Campus of the Federal University of Rio Grande do Norte UFRN. The prototype was designed and built seeking strategies of thermal comfort recommended for the local climate where the study was carried out, and built with panels of cellular concrete by Construtora DoisA, a collaborator of research project REPESC Rede de Pesquisa em Eficiência Energética de Sistemas Construtivos (Research Network on Energy Efficiency of Construction Systems), an integral part of Habitare program. The methodology employed carefully examined the problem, reviewed the bibliography, analyzing the major aspects related to computer simulations for thermal performance of buildings, such as climate characterization of the region under study and users thermal comfort demands. The DesignBuilder 1.2 computer application was used as a simulation tool, and theoretical alterations were carried out in the prototype, then they were compared with the parameters of thermal comfort adopted, based on the area s current technical literature. Analyses of the comparative studies were performed through graphical outputs for a better understanding of air temperature amplitudes and thermal comfort conditions. The data used for the characterization of external air temperature were obtained from the Test Reference Year (TRY), defined for the study area (Natal-RN). Thus the author also performed comparative studies for TRY data registered in the years 2006, 2007 and 2008, at weather station Davis Precision Station, located at the Instituto Nacional de Pesquisas Espaciais INPE-CRN (National Institute of Space Research), in a neighboring area of UFRN s Central Campus. The conclusions observed from the comparative studies performed among computer simulations, and the local records obtained from the studied prototype, point out that the simulations performed in naturally ventilated buildings is quite a complex task, due to the applications limitations, mainly owed to the complexity of air flow phenomena, the influence of comfort conditions in the surrounding areas and climate records. Lastly, regarding the use of the application DesignBuilder 1.2 in the present study, one may conclude that it is a good tool for computer simulations. However, it needs some adjustments to improve reliability in its use. There is a need for continued research, considering the dedication of users to the prototype, as well as the thermal charges of the equipment, in order to check sensitivity

Demographic and epidemiological transformations have led to an increase in elderly populations in the world, and chronic diseases become the main health problem in this population, with consequences for the independence and autonomy, and interfering in the lifestyle and daily activities, and may decrease the welfare and quality of life. So, there is an urgent need for multidisciplinary research on the quality of life, understood as a multidimensional and subjective concept, as well as the associated factors, such as health habits, presence of chronic conditions and functional capacity. Thus, In qualitative terms, the Article 1 provides an assessment and perception of the elderly about their quality of life. Article 2, in turn, presents the results of more extensive quantitative research, which can be seen that age, presence of chronic diseases and depression were associated with the quality of life. Thus, we discuss the need for action was planning and health strategies, with interdisciplinary approach, considering the environmental context and reality of family elders, promoting quality in the process of aging

The competition in the telecommunications industry has grown in Brazil since the privatization, forcing companies that are active in the market to a growing commitment to quality products and services in order to survive. In this context, this work aims to understand the main factors that influence the degree of satisfaction exists in respect of a mobile operator with its corporate customers. The research covered theoretical concepts and analytical models of quality management system and models of indices related to the measurement of customer satisfaction. For the field research was carried out in a practical application of the main approaches based on this thesis by a case study in corporate segment, through a questionnaire applied to 10 consultants and 40 corporate customers of that company. Comparing the results of research with the consultants and corporate clients there is the concern of respondents to the indicators that comprise the constructs of customer satisfaction, commitment calculated, the price index and the handling of complaints, denoting the dissatisfaction of the general assessment for corporate customers with the carrier, against its current expectations. It is concluded that the mobile operator of the telecommunications industry have a big challenge, after ten years of privatization and consequently the period of rapid expansion of customer base and with the depleted, retain corporate customers as highly strategic, thus avoiding that migrate to other companies. We emphasize the need for further research and analysis of different approaches through research and using the same models to specifically evaluate and measure customer satisfaction of mobile enterprise, to adjust the model to the national market. Finally, we suggest the creation of an effective customer loyalty program with a strategy of relationship and specific to the corporate sector of mobile telephony

Stabilization pond is the main technology used for treatment wastewater, in northeast Brazil, due to lower cost of deployment, operation and maintenance compared to other technologies. Most systems of stabilization ponds has been in operation for some time, on average 10 years of operation, receiving high organic loads and do not have good removal efficiencies of the main parameters for which have been designed. Therefore it is necessary to work to quantify the efficiency of current systems. This study evaluated the biodegradability of organic matter in raw sewage, the removal of organic matter in reactors and determination of the kinetic constant removal of organic matter (k), both in reactors and in raw sewage, based on the analysis made in the laboratory and through mathematical methods proposed in the literature, in nine systems stabilization ponds, located in Rio Grande do Norte. In relation the degradation kinetics in stabilization ponds, it was observed that many papers published in the literature were obtained in pilot-scale systems, which often, due to the action of external factors such as wind and temperature, these can t be considered as a reference in the analysis of the kinetic constant K, so the need for more research into systems of scale. This study had three distinct phases and simultaneous, routine monitoring, study of the daily cycle and the determination of kinetic constant of degradation of organic matter (K). The monitoring showed that the removal efficiencies of organic matter on most systems were lower than suggested by the literature, the best efficiencies of around 76% (BOD) and 72% (COD) and the worst of the order of 48% (BOD) and 55% (COD). The calculation of K in raw sewage (Ke) was within the range of variation expected in the literature (0.35 to 0.60 days-1). Already for the results obtained for K in the reactors (Kr), there were well below the values recommended in the literature (0.25 to 0.40 d-1 for complete mix and from 0.13 to 0.17 d-1 for flow dispersed), in line with the overloads that organic systems are subject

Introduction: Hypoestrogenism is the main characteristic of female aging. It promotes significant changes in body composition, both in fat mass as in lean body mass, leading to a decrease in muscle strength and physical performance. Objective: The aim of this study was to test whether menopausal status and hormone levels are associated with muscular strength and physical performance in middle-aged women. Methods: In a cross-sectional study it was collected sociodemographic data, gynecological history, anthropometric and biochemical measures in women aged 40 to 65 years in Parnamirim-RN. The menopause status (pre, peri and post menopause) was determined by menstrual history. All women underwent three dimensions of physical performance assessment: handgrip dynamometry, gait speed and chair stands test - Short Physical Performance Battery (SPPB). Categorical data were presented as absolute and relative frequencies. Quantitative data were showed as mean and standard deviation and the normality of distribution was verified with Kolmogorov-Smirnov (KS) test. Biochemical measures of estradiol and follicle-stimulating hormone (FSH) were transformed to log10. ANOVA with Tukey post-test for comparison of variables between the groups pre, peri and post-menopausal was performed and then multiple linear regression analyzes. Results: Two hundred and seventy eight women aged 50.2 (±5.58) years composed this study, being 50 women in premenopausal status (18%), 122 in perimenopausal (43.9%), and 106 postmenopausal stage (38.1%). The groups were different in age (p=0.001), marital relationship duration (p <0.001), number of pregnancies (p=0.001) and parity (p=0.001). Differences in biochemical measures were observed among the groups: estradiol (p<0.001), FSH (p<0.001), total cholesterol (p=0.001). There were no differences in gait velocity between menopausal status. Values in mean of grip strength decreased by postmenopausal women to perimenopausal and premenopausal ones (24.5 ± 5.1, 25.6 ± 5.4, 26.9 ± 4.9 for post-stage, pre and peri menopausas, respectively, p = 0.02) and the performance of chair stands test was better in premenopausal women compared with that in peri and postmenopausal status (p = 0.02). In multiple linear regression for muscle strength, the variables that remained were: age, estradiol and somatic symptoms measured by Menopause Rating Scale-MRS (R2=0.15). While for the xiv chair-stands test the predictors were number of births and FSH values (R2=0.04). Conclusion: There is a relationship between the stages of menopause and muscle performance in measures of grip strength and sit-up test and these are influenced by the fall of estrogens levels. Data suggest that the decrease in muscle strength and physical performance already appear in the transition to menopause stage, pointing to the need for more research in this area and appropriate preventive interventions

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

The present study focuses on the development of pedagogical activities in Music Teaching, aiming to enhance the accessibility of musical knowledge for both deaf and hearing students, using a bilingual approach in regular schools. Few studies address Music and Deafness, and those that do focus exclusively on the context of special education, and specifically the deaf student, which signals the urgent need for conducting research on this issue in the context of inclusion – empirically and carried out on school grounds. Therefore, we developed our study at a Natal City Public Elementary school, in a class of 6th graders, comprised of 37 students, 3 of whom were deaf. The objective of the study was to develop a proposal for a pedagogical intervention in Music Teaching, using a bilingual approach, with deaf and hearing students, in the context of regular school classes. The research is based on the theoretical framework presented in Penna (2010), Brito (2001) and Fonterrada (2008), with reference to music education, and Haguiara-Cervellini (2003), Finck (2009) and Louro (2006), with reference to inclusion in teaching music. To achieve this objective, we developed a proposal for intervention based on the methodological dictates of intervention research, presented in studies by Jobim and Souza (2011) in light of the theoretical concepts posited by Mikhail Bakhtin, which assert that knowledge is produced through interaction between subjects, dialogically and through alterity. This methodology was carried out in pedagogical workshops, conceived as spaces for the construction of knowledge, mobilizing participants to engage in ludic activities of musical experimentation. Content covered in these workshops focused on Pulse and Rhythm – basic elements in music education – demonstrating that awareness about and sensitivity to these elements is not limited to the auditory sensory perception of the student, once the entire body is used as an agent of acquisition and expression. Thus, we began the trajectory of our research from the starting point of the identification and perception of „Pulse‟, using one‟s own body and the body of classmates, representing it through physical expressions and movement. Subsequently, this Pulse was extended from the body to a percussion instrument, and was then represented graphically as lines of rhythm, constituting a process of reading and writing; ultimately the intervention culminated in the class presentation with the musical group De Pau e Lata (Stick and Can). In our analysis, faced with the challenges and possibilities presented in our study, findings showed satisfactory results with regard to the participation of all of the students: completing the activities proposed in the class, asking questions when they did not understand, positioning themselves when they thought it necessary, expressing opinions about the work completed, evaluating the workshops given, interacting, helping in the activities, constructing knowledge collaterally, experimenting and experiencing musical elements through the body in activities that applied to both groups (deaf and hearing) in the one class. These indications elucidate the viability of teaching music to deaf and hearing students, using a bilingual approach, and based on experiences with the body and communicative and cultural specificities involved, confirming, as well, the role of Sign Language as a mediator in the teaching/learning process.

This dissertation addresses issues considered essential for sustainable development of urban waterfronts and beaches. Many of these spaces, even though they are of public authorities, economic market and general population interests - due to its landscape, its importance for recreation purposes and as a basis of " Sun and beach Tourism " (Turismo de Sol e Praia), among other factors - have shown aesthetic, health and cultural degradation, entailing environmental, economic and social losses and conflicts. Based on this perception, the research aims to understand the main reasons for these negative results for beach spaces. To this end, it was chosen the case study of a typical urban beach, Ponta Negra Beach, located in Natal, RN. Ponta Negra is associated with the "postcard" of the city and it has been deserving of municipal urban planning legislation that legally recognizes the importance of its landscape. Also it has received constant investments by the Government through urban projects, arguing to leave the site attractive to its users. Nevertheless, in the last fifteen years, the beach has lived with the expansion of its problems, such as those related to bathing water, to coastal erosion, and to the mangling of its natural surroundings. Social conflicts have also been frequent in this time frame: conflicts between residents of the waterfront and traders who work on the beach, between the traders themselves, between the managers of space and fishermen, between managers and formal and informal traders. Many of these social and environmental conflicts have taken such grand proportions that became legal matters. Assuming that the problems identified are related to the issue of rationality - understood as a system of values, norms and actions that relate means and ends - and upholding the need for focused research on "environmental rationality" to understand and interpret the dynamics of social and environmental problems encountered on site, the research that guides the study relies on the Mexican economist Enrique Leff's theory on "environmental rationality" which, briefly, can be defined as a system of values, norms, actions and means and ends relations based on the principles of environmental management and sustainable development. Among other aspects, rationality encompasses cross-sectional planning of public administration, the participation of society in the management of environmental resources, interdisciplinary reorganization of knowledge, the clash of opposing interests and the conciliation of common goals of different social actors. The study evaluates the relationship between "environmental rationality", as proposed by Enrique Leff, with the management, urban interventions and uses observed in Ponta Negra Beach. For that, some benchmarks were established and considered in the research as related to sustainable development of the "beachy" atmosphere. Analytical instruments chosen were the urban transformations and the environmental and social problems that have been the target of lawsuits. Also part of the study, the problems that were the subject of civil investigations, which are investigation procedures carried out by the Prosecutor's Office.
