Ventilação e prescrições urbanísticas: uma aplicação simulada no bairro de Petrópolis em Natal/RN

The present work studies the natural ventilation and its relationship with the urban standards, which establishes the form of occupation and use of the land in our cities. The method simulates the application of the urban standards of the City Master Plan over the last three years. The simulation takes place in the District of Petrópolis, in the city of Natal , Brazil and analyses the effects of the standards of natural ventilation. The formulated hypothesis states that the reductions in the urban spaces between buildings rises up the vertical profile of ventilation, reducing, therefore, the velocity of the wind at the lower levels of the buildings. To develop the study, occupation models were built, using computerized, three-dimensional models. These occupation models were analyzed using the CFD (Computational Fluid Dynamics) code. The conclusion is that the more we reduce the urban space between buildings, the more we reduce the wind speed in constructed areas, increasing, therefore, the possibility to generate heat islands

Análise do monitoramento de descargas atmosféricas na área de concessão da companhia força e luz do oeste em Guarapuava, Estado do Paraná

Aiming to analyze the monitoring of the atmospheric discharges incidence, the concession area of Companhia Forca e Luz do Oeste (CFLO) - Western Power and Light Company, located in the district of Guarapuava, state of Parana was chosen for a study developed in 2003, from January to December. After the air masses dynamics description, it was possible to identify the occurrence of atmospheric discharges and to compare them to the energy interruptions. To that end, atmospheric discharges density maps were created within the CFLO concession area for a later analysis of their influence in the electric energy supply. The monitoring of the atmospheric discharges and the comparison between this phenomenon and the occurrence of interruptions in the electric energy supply enabled this study. Results showed that such events are directly related, and that the rural area of the region under study underwent a major interference.

Acesso aos serviços odontológicos e incidência de cárie em adolescentes e fatores de risco em município do Nordeste Brasileiro, 2006

The aims of this study were to analyze the access of dental services by child population, to determine the prevalence of dental caries, gingivitis and malocclusion in resident children from the municipal district of Sobral Ceará and to evaluate the incidence of the dental decay in adolescents associated with the factors related to socioeconomic condition, access to health services and self-perception. This study had as main factor the multidisciplinary represented by the participation of health professional (doctors, dentists, nurses) in the development of the survey's initial reference; student from Human Sciences area to apply the structured questionnaire in domiciliary visits; statistics professionals in the orientation of the analysis to be held and family health team (community health agents, dentists and dental clinic assistants) in the scheduling of domiciliary visits and the accomplishment of oral exam. The sample was determined from the domicile record that included children born between 1990 and 1994 to develop the research Children health conditions in the municipal district of Sobral Ceará . The first sample comprised 3425 parents of children from 5 to 9 years old, living in the urban area at the municipal district of Sobral Ceará, aiming at identifying the most important factors associated to the access to dental service. From this sample, 1021 children were selected in a systematic way, for the accomplishment to the epidemiological study of decay, gingivitis and malocclusion. In the study's third phase, in order to arrange the group to be followed, 688 adolescents were examined and interviewed, by means of the active search from the 1021 individuals that had been previously examined. It was observed that 50.9% of the children had access to dental service at least once in a lifetime. Of this total, 65.3% accomplished it during the last year, and 85.4% of these did in public services, what allows to identify the importance of this sector in the access to dental services. It was observed that the factors that most affected the access to dental 129 services were related to socioeconomic condition, such as the access to health plan, the possession of toothbrush, garbage collecting, mother s schooling, sewerage treatment and malnutrition. In relation to oral diseases, an increase in the DMF-T index according the age was observed, from 0.10 in five years old to 1.66 in the nine years old, while with the dmf-t index, the inverse happened, since the index decreased from 3.59 in five years old to 2.69 in nine years old. In relation to gingivitis, an average 32.7% of the children presented gum bleeding. In what concerns malocclusion, it was observed that 60.3% of the children didn't present any problem, 30.17% had light malocclusion and 9.5% severe malocclusion. The average incidence of dental caries was 1.86 teeth per youngster. Among the studied variables, tooth pain in the last six months, mother's income and school snack, adjusted by the perception about the need of treatment, the mother's schooling and the dentist's appointment at least once in a lifetime, were the variables that presented positive relationship with the high incidence of dental caries on this population by logistic regression. Variables of socioeconomic nature, related to the access to health services and behavior and biological variables presented a relationship with the high caries incidence. The study point out to the need of developing health actions in a humanized way, by an oral health team effectively bound to the population's interest, with the great objective to provide, with the public health services managers, adequate conditions to improve oral health

Apitidão funcional e comportamentos relacionados à saúde em mulheres idosas do município de Jequié-BA

The identification of the factors that interfere in the decline of functional conditions is useful in the planning of actions addressing the improvement in the conditions of the lives of elderly people. The purpose of this investigation was to analyze the relationship between social demographics and health aspects of the functional condition in elderly women of low income of the Brazilian northeast. This crosssectional study involved a representative sample of 222 women with an average age of 70 years (± 7.1), belonging to coexisting groups and that were resident in the urban area of the municipal district of Jequié /Bahia. In order to achieve this objective, a battery of physical tests of functional aptitude was carried out previously tested in pilot study, anthropometric measurements collected with a comparison of the measures referred to the reported weight and height as well as the application of an interview with questions containing subjects related to social demographic variables, clinical conditions and health, physical conditions and behaviors. Descriptive statistics Proceedings (frequency, average, standard deviation and percent distribution) were used for statistic analysis, and the calculation of the respective odds ratio by binary logistics regression, for the analysis of factors hierarchically grouped; p<0.05. The prevalence of 56% (n=122) of women considered with moderated or serious type of functional limitations was found, In which from multi-varied hierarchical analysis, significant association was verified with the age group over 80 years (p=0.02), conditions of widowhood (p=0.04), presence of arterial hypertension (p=0.001), and physical inactivity during leisure time (p=0.03). On the other hand for functional incapacities the prevalence was of 46.8% (n=104) being associated to the increase of the age (p=0.01), hospitalization (p=0.02), absence of physical activities along their lives (p=0.001) and the occurrence of alterations in the cognitive function (p=0.001). The normative table for the parameters of physical fitness generated conducive to health professionals in the diagnosis of health conditions and the prescription of physical exercises. The identified characteristics that are associated with the functional limitations / functional incapacities suggest a complex causal net in the determination of the functional condition in elderly women. However, actions addressed to the incentive of the practice of physical activities in the leisure time and the preservation of the cognitive function can contribute to a life with more quality for these people. This research was multidisciplinary approach to involve elements of psychology, nutrition and Physical Education in the elucidation of the object of study related to the functional condition of elderly women

Avaliação das condições higiênico-sanitárias da produção de refeições à base de carne da alimentação escolar no município de Natal-RN

The National School Nutrition Program is the oldest program in the country directed at food and nutrition safety. Its aims are to offer nutritional food as a supplement to students of public and philanthropic schools. Studying school nutrition transcends the investigation as a purely social program, given that it reaches the fields of public health, nutrition and food, using a wide variety of approaches. Thus, it is characterized by a multidisciplinary study, where the disciplines work side by side in distinct aspects of a single problem. Aim: This study aims to assess hygiene practices during the preparation of meat-based meals in public schools in the city of Natal, Brazil. Methods: A list was applied at 27 schools to identify the procedures of good food preparation practices. In addition, cooking and meal distribution temperature were measured and a microbiological analysis of the final preparation and of the water used in preparing it was performed. For microbiological analyses of the food, we analyzed coliforms at 45°C, coliforms at 35°C and Enterococcus, and for the water, we analyzed thermotolerant coliforms and total coliforms, using the methods recommended by APHA, 1995. Results: Most of the schools did not meet the required standards in all the variables related to good food preparation practices, except for the time spent preparing the meat, in which 89% were within the norm. Cooking temperature of the meals was within the standard; however, the temperature at distribution and the time spent dispensing the meals were inadequate. Of the 27 schools, 22 (81.5%) showed the presence of coliforms at 35° C in at least one meal sample and 18 (66.7%) had values above the recommended limit for coliforms at 45°C. The presence of E. coli was identified in 6.1% of the samples analyzed. The presence of Enterococcus was not found at any of the schools. With respect to the water, the North district of the city was the only one that did not meet the standards for the two indicators evaluated. The contamination found was not associated with the hygiene or food storage problems observed. Conclusions: The results show that the hygiene-sanitary conditions of meat-based public school meals were unsatisfactory, demonstrating the need for improvements in the production process to preserve the health of the student population. Multidisciplinarity: Researchers from the areas of food microbiology, nutrition, public health and statistics took part in this study, a decisive factor for characterizing the research as multidisciplinary

EMPRESAS DA CONSTRUÇÃO CIVIL DO MUNICÍPIO DE ARACAJU-SE: Percepções sobre Responsabilidade Social Empresarial

The companies are part of an important segment of the society, besides, it exercises a significant contribution, being also responsible for helping in the improvement of the quality of life of the population. Like this being, to present research looked for to investigate the perception that the entrepreneurs of the building site of Aracaju/SE have concerning the theme Business Social Responsibility (RSE). besides the perceptions, it was part also of the research, to know the entrepreneur's of the building site social construction and the possible practices of Social Responsibility. The research grew in two different moments. The first looked for the theoretical embasamento, trying to study the economical sociology, understanding the effects provoked by the economy, understanding to you reason them that you/they took to the appearance of the perceptions that you/they permeate the historicity among the market, the nascedouro of the associations as company and his/her dynamics in the society. It was also researched, the concept of social responsibility in national and local extent, as well as, the contextualização of the state of Sergipe, detaching the municipal district of Aracaju, and describing how it happened his/her development starting from what is considered urbanization. In the second moment, the accomplishment of interviews in five companies, allowed to notice the entrepreneurs' perception concerning business social responsibility, as well as, actions of different characteristics in four of the samples. In these actions, they are patronage in cultural events, donations of projects for charity institutions, the concern with the preservation of the environment in the use of work materials ecologically correct, preventive health and employees' training. Concluding the research, I introduce the conclusions which it allowed to arrive me, and I point some suggestions for future researches that enlarge the reflection on this theme

Um olhar sociológico sobre a criança e o brincar: espaço e tempo de construção, reinvenção e aprendizagem

This research I discuss the play, also talking with the other subjects that make up the universe in which the play is inserted, such as family, school and culture. The fundamental proposition of this dissertation assumes that the absence of play in children's lives affect their physical structure, psychological, biological, cultural, social, historical and theirs development. The initial questions were: What are the spacetimes reserved in the school for play? What is the importance of play in the development of children? Does the school recognize the importance of play in its social space? How the children perceive and use the spacetimes to play at school? Are there spacetimes at school to play? This is a theoretical and empirical research of exploratory study. The research‟s field was the Municipal School Professor Ulysses Góes, located in district of Nova Descoberta, in Natal, Rio Grande do Norte and, as research techniques, I used: participant observation, photography, structured interviews with students and questionnaires with teachers. The results indicate that for most of children, the school allows the play, few disagree with this preposition.Teachers recognize the importance of play in school, but for various reasons do not provide your practice. The dissertation points the possibility of new studies and developments for the theme.

Toxicidade do herbicida S-metolachlor em plantas de milho provenientes de sementes com diferentes formatos e dimensões

Este trabalho teve como objetivo avaliar a toxicidade do herbicida S-metolachlor em plantas de milho oriundas de sementes com diferentes características morfológicas. O experimento foi conduzido em casa de vegetação, localizada no município de Capão do Leão, RS. Os tratamentos foram compostos pelas combinações de três grupos de tamanhos de sementes, classificadas em peneiras de crivo oblongo [sementes retidas nas peneiras de largura 14/64 (peneira 14), 18/64 (peneira 18) e 21/64 (peneira 21)], de dois formatos de sementes (chata e redonda) e de cinco doses do herbicida S-metolachlor (0,00; 0,48; 0,96; 1,44; e 1,92 kg ha-1), totalizando-se 30 tratamentos. O delineamento experimental utilizado foi o de blocos casualizados em esquema fatorial (3 x 2 x 5), com quatro repetições. Após a separação e classificação das sementes, procedeu-se à semeadura em vasos preenchidos com solo homogeneizado. em cada vaso foram semeadas oito sementes de milho, na profundidade de 3,0 cm, realizando-se, 24 horas depois, a aplicação do S-metolachlor em pré-emergência. Foram realizadas as seguintes avaliações: velocidade de emergência das plântulas; número total de plântulas emergidas; toxicidade visual e altura de plantas aos 7, 14 e 21 dias após a emergência (DAE); e biomassa seca das raízes e da parte aérea aos 21 DAE. O formato das sementes se mostrou fator importante na tolerância das plantas aos efeitos tóxicos do herbicida S-metolachlor, aplicado em pré-emergência, quando as sementes de milho são de menor tamanho, sendo observada maior toxicidade quando as plantas eram provenientes de sementes redondas. O aumento das doses aplicadas do S-metolachlor ocasionou reduções na aquisição de biomassa seca tanto da parte aérea como das raízes de plantas de milho, porém maior decréscimo se observou quanto ao acúmulo de biomassa seca das raízes.

Modos de ser e modos de viver : a trajetória dos estrangeiros em Natal/RN

This work aims to understand the trajectory of immigrants living in Natal / RN, between the years 1990 and 2009, their motivations for this change, their sociability relations, as well as the impact of this group in Natal and specifically, in the district of Ponta Negra, where most of them established their residences or work. Considering that the historical, political, economical and social environment where these immigrants are inserted, are different from that experienced by former immigrants who came to Brazil in the late nineteenth and early twentieth centuries, a period of mass migration, it was revealed that immigration studied in contemporary Natal constitutes a new configuration (Elias, 1994). This new configuration is represented by several characteristics that distinguish this contemporary immigration, as: the relationship established by these foreigners, both with their country of origin and the destination, the formation of social networks that offer support to newcomers and those already installed, the relations of sociability with locals and a new relationship of belonging with the space, since the possibility of coming and going from one country to the other, allows a (re)production of their original ?? social and economic life in the new space. The research methodology was based on the analysis of narrative interviews, in light of the theory of Schütze (1977) in order to understand the faces of this immigration. As theoretical support for the data analysis the theories of authors such as Norbert Elias, presentedin his work about the established and outsiders, Pierre Bourdieu, and his concept of habitus, distinction and style of life, Georg Simmel, and his study of life in the metropolis, his analysis of the foreigner and his theory of sociability, among others. This study attempted to give visibility to foreigners living in Natal, who experience the dynamics of the district of Ponta Negra and reconstruct their daily relations of sociability in this space. In fact, the presence of foreigners in this urban context allows for the construction of new configurations, both in terms of the physical space of the neighborhood, which has been modified by the touristification process and the real estate market, which is molded to meet this demand, but also in their social sphere, with regard to the relations established between foreign residents and locals. In seeking to characterize these migratory experiences it could be understood that the trajectories of each foreigner is part of a broader social structure, which cannot be evaluated neither disconnected from the contexts in which they operate, nor under a single point of view

A arte rupestre como expressão comunicativa da cultura

Along their existence, through of the millenniuns, the Man registers, one way or another, their saga. One in those registration ways is the rupestrian art. Through the rupestrian art the Prehistory is brought even us, portraying in images the daily ritualist and magic of the Man, in scenes that show, among other, their cults and also their daily hard work. The Man is imposed, while registering of their existence, starting from the moment in that he is capable to leave their marks through the transformation that attributes to the Nature; also for the produced interferences and for the cultural singularities that themselves were constituted before the period of the alphabetical writing. In an artifice of duplicating utensils and in the sense of representing animals and to himself own, he delegated us a communicative system whose contexts and details were - and it continue being - an enigma to be deciphered. Starting from this argument, the research has for objective to understand the daily and the history of cultural groups that they preceded us, taking as base the reading of the rupestrian paintings found at the located archeological ranches in the Area of Seridó, more specifically in the Complexo Xique-xique, close to the Municipal district of Carnaúba dos Dantas, distant 220 kilometers of Natal, the capital of Rio Grande do Norte State

Efeito de rodas compactadoras submetidas a cargas verticais em profundidades de semeadura sobre o desenvolvimento do milho

O sucesso de implantação de uma cultura pode ser garantido por uma semeadura bem realizada, e as rodas compactadoras utilizadas nessa operação devem ser capazes de melhorar o contato solo-semente para promover boa emergência das plântulas. O objetivo deste trabalho foi estudar a influência de três modelos de rodas compactadoras, três profundidades de semeadura e três níveis de carga sobre a roda compactadora na germinação e no desenvolvimento da cultura do milho, em uma pista de ensaios projetada para essa finalidade, no município de Uberaba - MG, em Latossolo Vermelho distrófico, textura média. O delineamento experimental utilizado foi o de parcelas subsubdivididas, com 27 tratamentos e quatro repetições. Os resultados obtidos evidenciaram que a profundidade de semeadura foi o fator que mais afetou o desenvolvimento vegetativo da cultura do milho no estádio 2, enquanto no estádio 4 nenhum dos fatores afetou as medidas de desenvolvimento da cultura.

Habitus, representações sociais e construção identitária dos professores de Maracanaú

In the last three decades, the subject of the teacher's social identity has been discussed under various theoretical focuses, not only in Brazil, but also beyond our borders. In this thesis, the theme is approached starting from the theoretical proposal that has been developed by Domingos Sobrinho (1994), which is strongly based in the epistemological approach between Pierre Bourdieu’s praxiology and the Theory of the Social Representations formulated by Serge Moscovici. It presupposes that this would make it easier to apprehend the process of construction of social identity of the investigated social group. The universe of the research is constituted by teachers of the fundamental teaching of the municipal district of Maracanaú, state of Ceará, that were active in class-room work there during at least three years, and were registered or had concluded the Course of Educational Formation promoted by UECE in that municipal district. Taking into account that the teacher's social identity is a process in permanent construction, resulting of their daily experiences and of the interferences originated from of the social context, the investigative tasks were implemented in two different stages, although they complement each other. Initially, with the objective of putting in evidence the genesis of the formation of that group’s habitus, an analysis of the family and school lives of eleven teachers who participated in the course was made, using as main sources of data: thematic memorials, semi-structured interviews and observations - inside and out of the class-room – during four school semesters. In the second stage a test of free association of words was applied to 426 teachers, seeking to apprehend the structure of the social representations of family and school – a methodological strategy considered necessary to enhance and identify certain outlines of the habitus in study, besides being in agreement with the theoretical model followed. It became evident from the results that the identity of Maracanaú’s teachers is molded and transformed into a multifaceted dynamic unit that shows successes and mistakes, certainties and doubts. For instance, besides an innovative speech seeking to reassure that teaching is a profession and not a simple vocation or mission, some discourse and attitudes are identified that point to the opposite direction, extolling the school as extension of the family, defending a parental relationship with the students, and looking at certain aspects of daily school life as “sacramental”. However, in the light of science such ambiguities and incoherences are inherent to common sense discourse, where the influences of the patterns and cultural references are present in the process of identity construction of the group, which was confirmed by the research of their social representations of family and school

Saberes e práticas em experiência de construção da sustentabilidade no meio rural nordestino

The purpose of this work is to analyze the knowledge relationships that articulate in projects of maintainable rural development construction for the paraiban semi-arid, analyzing the farmers daily practices and their relationship with the technological practices spread by ONGs. We took as empirical object the rural community of Lajedo de Timbaúba, municipal district of Soledade-PB, located in the very small region of paraiban Curimataú. It is a community where registers one of the first cases of maintainable rural development planning in the state of Paraíba. The analysis was centered on the farmers experiences of life in sustainability experience, trying to understand how they acquire new knowledge and how they interact with them. In methodological terms, it was considered feasible to place the knowledge interaction between the farmers and technicians from ONGs by placing the analysis according to Paulo Freire s questioning (2006): extension or communication? To understand the farmers daily practices, it was resorted to the theoretical contribution by Michel de Certeau (2008) in order to discern a microresistance movement of inversion/rejection/changing by the farmers in relation to their external knowledge. Just from the theoretical point of view and resorting to the imaginary social by Cornelius Castoriadis (1982), it was considered the way of living of the farmers researched, having as reference the experience in the material and symbolic production of their lives. It became indispensable, therefore, not to dissociate the knowledge relationships between farmers and technicians from ONGs from the sustainability concepts, maintainable rural development, and rural extension. The results of the study revealed that the farmers from Lajedo de Timbaúba while dealing with the technological practices proposed by ONGs that work in the community, express those practices from their daily logic, and they constitute them in survival strategies that are inserted in their own idiosyncrasy. It was verified, therefore, that the external knowledge presented by the proposals of sociability alternatives with the droughts in the perspective of maintainable development while placed in the farmers daily relationship, they are judged as advantageous or disadvantageous when they are confronted with their peculiar way of doing their daily work. The technological practices are incorporated, denied, or recreated starting from evaluative criteria related to the preservation of the soil and to the economical and social reproduction of the unit of production of family agriculture

Relações entre teorias da história e ensino de história: a compreensão de professores

This thesis has as an objective to think over the teachers` understanding of the school History of the Fundamental Teaching regarding the existent relations between the history theories and the teaching of the school History, as well as to think over how these teachers see the influence that their teaching practice gets from the history theories. The work is based on the postulates of the qualitative research and on the characteristics of the ethnography of the school practice. The main procedures of data gathering were the documental analysis, the semi-structured interviews, the field diary and the observations of classes. The scientific perspective of the multiple references is an important source in this research. The participants of this work are two teachers of the school district of Natal who work in the field of the school History in two schools on the North Side of the city. The accomplished analysis point to significant indications that didn't occur continuous and regular teaching situations in the initial and continuing education of these teachers that clearly showed the relations between the history theories and the teaching of the school History. They also suggest that their understanding about the influence that their teaching practice gets from the history theories, is not still explicit. We understand that the relations between the history theories and the teaching of the school History are important for the initial and continuing education of these teachers who belong in this knowledge field, even when these relations are not explicitly pointed by the teachers, because they will always influence the teaching practice that the teachers of the school History build
