Elaboração de uma unidade de ensino potencialmente significativa em Química para abordar a temática água

The evidence of the water theme in news reports is configured as an important topic of interest to contextualize, problematize and/or generate meaning in the midst of discussion of a content from different levels of education and/or disciplines of basic education. The possibilities to use this theme in classroom is also highlighted in Brazilian official documents that guide the practice of teachers of all Brazilian curricular components of this educational level. So, the theme water can be used as subsidy to teach chemistry, since contextualises the teaching of this discipline aiding in the discussion of different chemical concepts. In this perspective, the meaningful learning theory, developed by David Ausubel, has constructivist nature and says that an individual learns significantly when he can relate new information with a specific knowledge structure that integrates the prior knowledge of its structure. In this sense, the use of water as a theme for the approach prior knowledge of chemical concepts has already been characterized as an important topic that can give meaning to the content of education in chemistry. In this dissertation, a teaching unit potentially significant (TUPS) is presented based on meaningful learning theory of David Ausubel approaching the theme water. approaching the theme water. The unit was used in a class of thirty-five students of the 2nd year of high school, a public school in the city of Extremoz-RN, metropolitan region of Natal / RN. Through it was possible to discuss an issue of interest to students of the school to address the chemical contents, such as solutions, physicochemical aspects and stages of water treatment. At first, an initial questionnaire was used to identify the students' previous ideas on the topic under study to the concept of chemical solutions. It was subsequently developed and implemented a series of activities based on students' ideas. To subsidize the sequence, it was prepared four booklets that worked the content of chemical solutions, contextualizing the theme water. The results of this work showed that the alternative conceptions that students have about concepts related to the chemical solutions are similar to the ideas of other students presented in the literature and that the development of the TUPS, allied to the contextualization strategy with the theme water, not only motivated the students for the teaching of chemical content, as yet provided the learning of chemical concepts not in isolation, but making a connection between their ideas and experiences with scientific knowledge. To this, beyond of dialogued lectures, were also used strategies as experimental activities, problem solving, group discussions and construction of concept maps. The final evaluation of the unit was conducted by a questionnaire based on the Likert scale, answered individually by students, who approved the unit as conducive to teaching and learning of chemistry process

A relação entre transtorno da insônia e funções executivas em adultos

The insomnia disorder is defined as a difficulty initiating or maintaining sleep or waking up earlier than expected unable to return to sleep, followed by a feeling of nonrestorative and poor quality sleep, present for at least three months, with consequences on daytime functioning. Studies have shown that insomnia affects cognitive function, especially executive functions. However, researches that sought to investigate the relationship between primary insomnia and executive functioning were quite inconsistent from a methodological point of view, especially in regard to the variability of the used methods, the heterogeneity of diagnostic criteria for insomnia and the control of sleep altering drugs. In this sense, the present study aimed to investigate the relationship between insomnia and executive functions in adults. The participants were 29 people, from both genders, aged 20-55 years old. Participants were divided into three groups, one composed of 10 people with primary insomnia who used sleep medication (GIM), nine people with primary insomnia who did not use medication (GInM) and 10 healthy people who composed the control group (CG). The research was conducted in two stages. The first one involved a diagnostic evaluation for insomnia disorder through a clinical interview and the application of the following protocols: the Athens Insomnia Scale, the Insomnia Severity Index, Sleep Journal (for 14 days), Pittsburgh Sleep Quality Index (PSQI), the Stanford Sleepiness Test, depression and anxiety Beck inventories, and Lipp’s Iventory of stress symptoms for adults. After this stage, the evaluation of executive functions was performed by applying a battery of neuropsychological tests composed by the following tests: Wisconsin, Stoop Test, Colored trails Test, the Tower of London Test, Iowa Gambling Task (IGT) and WAIS III subtest digit span, which measured selective attention, inhibitory control, cognitive flexibility, planning, problem solving, decision making and working memory, respectively. The results showed that insomniacs (GIM and GInM) showed higher sleep latency, shorter sleep duration and lower sleep efficiency compared to the CG. In regard to the performance in executive functions, no statistically significant difference between groups was observed in the evaluated modalities. However, the data show evidence that, compared to GInM and GC, the performance of GIM was lower on tasks that required quick responses and changes in attention focus. On the other hand, GInM, when compared to GIM and GC, showed a better performance on tasks involving cognitive flexibility. Furthermore, impaired sleep measures were correlated with the worst performance of insomniacs in all components evaluated. In conclusion, people with the insomnia disorder showed a performance similar to healthy people’s in components of the executive functioning. Thus, one can infer that there is a relationship between primary insomnia and executive functions in adults.

A geometria do compasso (1797) de Mascheroni (1750 – 1800) em atividades com o GeoGebra

The present work aims to show a possible relationship between the use of the History of Mathematics and Information and Communication Technologies (TIC) in teaching Mathematics through activities that use geometric constructions of the “Geometry of the Compass” (1797) by Lorenzo Mascheroni (1750-1800). For this, it was performed a qualitative research characterized by an historical exploration of bibliographical character followed by an empirical intervention based on use of the History of Mathematics combined with TIC through Mathematical Investigation. Thus, studies were performed in papers dealing with the topic, as well as a survey to highlight problems and /or episodes of the history of mathematics that can be solved with the help of TIC, allowing the production of a notebook of activities addressing the resolution of historical problems in a computer environment. In this search, we came across the problems of geometry that are presented by Mascheroni stated previously in the work that we propose solutions and investigations using GeoGebra software. The research resulted in the elaboration of an educational product, a notebook of activities, which was structure to allow during its implementation, students can conduct historical and/or Mathematics research, therefore, we present the procedures for realization of each construction, followed at some moments by original solution of the work. At the same time, we encourage students to investigate/reflect its construction (GeoGebra), in addition to making comparisons with the solution Mascheroni. This notebook was applied to two classes of the course of Didactics of Mathematics I (MAT0367) Course in Mathematics UFRN in 2014. Knowing the existence of some unfavorable arguments regarding the use of history of mathematics, such as loss of time, it was found that this factor can be mitigated with the aid of computational resource, because we can make checks using only the dynamism of and software without repeating the construction. It is noteworthy that the minimized time does not mean loss of reflection or maturation of ideas, when we adopted the process of historical and/or Mathematics Investigation

Mobilização de competências na atividade informal do vendedor ambulante em praia de Natal (RN)

The central issue of this dissertation is to investigate the labor activity of beach hawker, in order to identify the main professional competencies mobilized in this activity, traversed by both the precariousness of the means of labor exercise, as for complex and structured routines. In the town of Natal (RN) the beaches serve as workplace for thousands of informal workers, who use various professional skills, translated into the ability to mobilize and articulate knowledge, skills and behaviors to solve problems in concrete work situations. This research therefore had as main objective to investigate the work of beach hawkers, trying to identify the core competencies mobilized for facing demands and obstacles in such a context. The beach of Ponta Negra (Natal-RN) was chosen as field of observation, in which a group of hawkers took part as voluntary subjects. Methodologically, quantitative and qualitative methods of production and analysis of data were combined in three stages. In the quantitative phase an occupational questionnaire was applied to a sample of 60 subjects, generating a set of data analyzed with quantitative univariate and multidimensional descriptive statistical tools, complemented by inferential statistical analysis. The results of this phase indicate a predominance of men sellers with salary varying in a range from one to two minimum wage Brazilian salary, age and education quite heterogeneous, extended working hours and the choice of only this activity and this beach throughout the year. Concurrently with this step of analysis, unsystematic observations of the activity of vendors were held and then driven to the technique of Instruction Impersonator with four chosen subjects. This phase had a clinicalinterpretive analysis, rooted in historical-cultural Vygotskian psychological perspective and in the french approach of skills and abilities. The main results point to several strategies for overcoming obstacles, use of technics anchored in everyday work experience and practical knowledge, building rules of conduct and collective mobilization of diverse professional skills similar to those found in formal work, such as business and time management, use of communicative tools, flexibility in problem solving, creativity and teamwork competence. We conclude that informality investigated in context can not be seen exclusively as a synonym of precariousness. It also covers skills and knowledge in a complex culture that situates informal labor in a complementary way with respect to formal work. This conclusion, therefore, contributes to overcome the notion of antinomy between formal and informal labor activity, since they both can be considered as a way to achieve job satisfaction, and even a personal representation of well done job, which is an important psychological generator of identity and social place.

Efeitos de um programa de treino cognitivo e das técnicas de higiene do sono para as funções executivas e para a qualidade de sono em idosos saudáveis

The aging process causes changes in the elderly’s sleep/awake standard impairing their cognitive abilities, particularly executive functioning, which already suffers loss by aging. The literature suggests that executive function and preserved sleep quality are key to maintaining good quality of life and independence of older people, requiring interventions to minimize the impact of losses incurred by the aging process. This study evaluated the effect of a cognitive training program and sleep hygiene techniques for executive functions and sleep quality in healthy older people. The participants were 41 healthy older adults, of both sexes, who were randomly divided into four groups: control group [GC], cognitive training group [GTC], sleep hygiene group [GHS] and training group + hygiene [GTH]. The research was developed in three stages: 1st - initial assessment of cognition and sleep; 2nd - specific intervention to each group; 3rd - post-intervention revaluation. The results showed that GTC had significant improvements in cognitive tasks flexibility, planning, verbal fluency and some aspects of episodic memory, besides gains in sleep quality and decrease on daytime hypersomnolence. The GHS improved sleep quality and daytime sleepiness as well and had significant improvements in insights capacity, planning, attention and in all evaluated aspects of episodic memory. The GTH had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. The CG showed significant worsening in excessive daytime sleepiness in capacity planning. Thus, we conclude that cognitive training interventions and sleep hygiene strategies are useful in improving cognitive performance and quality of healthy elderly sleep.

Governança metropolitana e sustentabilidade: uma análise da gestão dos resíduos sólidos em Natal e Parnamirim

Nowadays the rapid growth of urban centers, the accumulation of social and environmental demands, the relationship between public policy and increasingly complex problems accentuates the feeling that cities undergo an urban crisis. This crisis is especially characterized by its multidimensionality, which goes through economic, cultural, ethical, environmental and, above all, political issues. In order to study the core of this crisis that is manifested by the urbanization process and has in its exacerbation on the metropolitan areas was conducted conceptual and theoretical study of the meaning of sustainable development applied to the everyday reality of cities, extracting from this debate concepts, such as: sustainable territorial development, administrative sustainability and political sustainability. Looking forward to test this the practical applicability of these theoretical concepts studied, an empirical study was done on the reality of metropolitan solid waste in Natal, Rio Grande do Norte, Brasil. According to the recent theoretical debate, the waste comprises a sector of the urban environmental crisis that best represents the relationship between man and environment. Ensuring the multidimensionality of environmental issues through the “Saber Ambietal” (LEFF, 2005), was made a extensive qualitative study correlating the concepts of sustainable territorial development, metropolitan governance and “Saber Ambiental” applied on solid waste. The results point to the real challenges of municipal government in understanding the real situation, take action and change the inertia in which have operated in recent decades. The results also showed the importance of transforming environmental issues in political, in other words, struggle for ideas, ideological and ethical references.

A dinâmica geográfica da construção de um território para moradias sociais: estudo testemunhal do empreendimento Vitória Brasil em Uberlândia (MG)

This work describes and analyzes the situation planned with the current, according to the housing development project style of social interest (Gleba 9), named Victory Brazil at Shopping Park II neighborhood, located in the southern sector of Uberlândia (MG), built with Program resources Minha Casa, Minha Vida (PMCMV). The specific objectives are: to present the housing policy of social interest directed to the Minha Casa, Minha Vida in the city of Uberlândia, from its history to its current information; trace the environmental characterization of the housing Vitoria Brazil through the development of thematic maps; identify the impacts generated by the housing projects of social interest; and show through interviews with 25 residents of Vitoria Brazil, the structural problems of the houses. Therefore, the research became quali-quantitative with descriptive approach and use of semi- structured interviews to collect data. In addition, the iconographic sources, ie photographs of the problems raised by the residents of the whole Victory Brazil and maps of the study area, enlarged the qualitative and dialogic nature of this study, as there is opportunity to contextualize specific way what was reported the residents interviewed. We understand that the city is intrinsically related to the design of agglomeration, characterized by the production of the possessor market capitalism a public administration system that is guided by the ideals of consumption and utilization of space, and its inhabitants are high class with the construction of equipment and adequate social services. One of the important biases to solving the problems of urbanization is by the intervention of the government through public policies through the master plan so that would allow prospects to enable the population of low-income housing in locations that offer housing and decent urbanization conditions.

Análise do uso de escalas nas simulações de processos de estampagem

The purpose of using software based on numerical approximations for metal forming is given by the need to ensure process efficiency in order to get high quality products at lowest cost and shortest time. This study uses the theory of similitude in order to develop a technique capable of simulating the stamping process of a metal sheet, obtaining results close to the real values, with shorter processing times. The results are obtained through simulations performed in the finite element software STAMPACK®. This software uses the explicit integration method in time, which is usually applied to solve nonlinear problems involving contact, such as the metal forming processes. The technique was developed from a stamping model of a square box, simulated with four different scale factors, two higher and two smaller than the real scale. The technique was validated with a bending model of a welded plate, which had a high simulation time. The application of the technique allowed over 50% of decrease in the time of simulation. The results for the application of the scale technique for forming plates were satisfactory, showing good quantitative results related to the decrease of the total time of simulation. Finally, it is noted that the decrease in simulation time is only possible with the use of two related scales, the geometric and kinematic scale. The kinematic scale factors should be used with caution, because the high speeds can cause dynamic problems and could influence the results of the simulations.

Estratégias de promoção da saúde a partir da escola e da Unidade Básica de Saúde da Família, em Uberlândia (MG)

Health promotion is opposed directly to the biomedical model and established by intersectoral action, with collective and interdisciplinary approaches, considering the subject in their life contexts. Build healthy territories is to promote health, which necessarily includes intersectoral coordination and community mobilization. The health and education sectors can work together to promote health, developing so articulate actions and practices involving the subject in its territory of life and work. This study aimed to design and experience of health promotion strategies in school and Basic Health Units Family in Uberlândia - MG, from intersectoral relationship and community mobilization. The methodological research route was action research, or research intervention, because while researching already applied the ideas to solve problems through collective action. The research began in the Municipal School of Basic Education Prof. Eurico Silva, with the Health Centre's deployment to carry out surveillance and health promotion with active participation of students, involving all subjects of the school, students, teachers and other staff in the context of everyday life, which extrapolates the school walls, reaching the family and social groups in the community to which they belong. The health observatory has the objective existence with the establishment of the working groups, which at first were "healthy eating" and "drug-free world" and later, "dengue". The themes were chosen by the participants of the Health Centre, in which each is involved preferably. The second part of the research started with the approach between the Centre for Health and the health units (UBS and BFHU). The proposal was that the schools and the health nurse unit together should undertake prevention and health promotion, combating Aedes aegypti with intersectoral coordination and community mobilization. For it was crucial the involvement of ACS, ACE, ASE and the nurse coordinator of the Health Unit in creating community networks in the territory. home visits, community mobilization and intersectoral coordination: a training course in all BFHU and UBS teams with the following subjects was conducted. At this stage, were the Health Units that should approach the schools, in order to provide community networks to fight Aedes aegypti in each territory. The results and the scope of this experiment could only be brought to fruition because the Board of Health Surveillance and Care Coordination council of Basic embraced the proposal and helped in its implementation. It remains to continue consolidating this process of work in health units of primary care and the elementary schools, replicate the Health Centre's experience at school. The conclusion of this work is that schools and care facilities to health together with intersectoral coordination and community mobilization supported by community networks, can carry out prevention and health promotion, from a health model that considers the social determinants of health and overcoming hygienist model / sanitarian.

O DISCURSO AMBIENTAL JORNALÍSTICO, POLÍTICO E EMPRESARIAL EM ÂMBITO LOCAL: uma proposta de análise

Esta tese tem como tema principal o discurso ambiental local. Trata-se de uma proposta de análise, que pode ser aplicada a este tipo de discurso em qualquer localidade, e um estudo de caso, que aplicou a análise proposta na tese. O objetivo geral desta pesquisa foi analisar a informação local sobre meio ambiente veiculada por meio dos discursos jornalístico, político e empresarial, estabelecendo relações históricas, sociais e ideológicas do discurso ambiental que permeiam as três áreas em questão. A metodologia incluiu três fases: pesquisa bibliográfica e revisão de literatura sobre os principais conceitos levantados no trabalho; levantamento de discursos locais disponíveis na mídia para análise no estudo de caso; análise dos discursos a partir de protocolo elaborado com base na Análise do Discurso de linha francesa. O estudo de caso traz a análise do discurso ambiental no município de Frutal-MG, onde hoje estão em andamento várias pesquisas e projetos na área ambiental. A principal conclusão do trabalho confirma a hipótese da pesquisa de que a informação ambiental fruto dos discursos político, jornalístico e empresarial em âmbito local tem caráter predominantemente situacional, mercadológico e propagandístico, pouco focada em conscientizar e educar e com ênfase em interesses comerciais e eleitorais e na resolução de problemas emergenciais

COMUNICAÇÃO INSTITUCIONAL E UNIVERSIDADE: diretrizes para a divulgação científica no estado de Mato Grosso

O estudo visa identificar as iniciativas de Divulgação Científica empreendidas pela Universidade Federal de Mato Grosso (UFMT) e Universidade do Estado de Mato Grosso (Unemat), com vistas à atualização e ao aperfeiçoamento da comunicação institucional, maior interação com interlocutores e fortalecimento da imagem do estado como produtor de CT&I. Foram empreendidas pesquisas bibliográficas e documentais, áreas prioritárias de fomento e difusão científica; entrevistas; auditoria de imagem na mídia estadual; diagnóstico dos principais produtos de jornalismo científico desenvolvidos pela UFMT e Unemat, assim como iniciativas conjuntas (revista Fapemat Ciência e Rede de Divulgação Científica). O método investigativo adotado pode ser caracterizado como Pesquisa Participante, concebido em estreita associação com resolução de problemas, tomada de consciência ou produção de novos conhecimentos (THIOLLENT, 1996, 1997). Tal estratégia agrega distintas técnicas de pesquisa social, definidas em função de cada fase do processo de investigação. A partir da análise dos conteúdos científicos publicados nos jornais estaduais, foi possível verificar que essas IES públicas ainda não ocupam lugar relevante em tais veículos, o que pode ser justificado pela inadequação de linguagem ou canais de relacionamento, assim como, pela necessidade de uma política de divulgação mais eficiente. O mapeamento dos portais e canais de mídias sociais institucionais evidenciou que a utilização desses veículos ainda pode ser mais bem dinamizada. Por fim, as conclusões apontam que diferenças culturais e institucionais entre as duas IES inviabilizam a adoção de uma Política de Comunicação Científica integrada, comum entre UFMT e Unemat. O que pode ser considerado, é o desenvolvimento de ações para a dinamização de divulgação dessas instituições, no âmbito do Sistema Estadual de CT&I.
