Knowledge is understanding. According to the philosopher Gaston Bachelard our immediate contact with the reality is only worth as confusing and provisional data. This phenomenological contact requires inventory and classification. For this reason our first reading on any phenomenon is limited to a basic levels of reality. Elements such as dynamics, functioning or detailed characteristics of what is observed can only be accessed at higher levels of reality, explains the physicist Werner Heisenberg. The ideas woven by these two great intellectuals oxygenates the notion that a well-made thinking does not require only observation and description of the nature, but assigns value and meaning to the knowledge. Based on these ideas and on the cognitive horizon brought by the complexity sciences, this research aims to nurture a reflection on our understanding of the world built from a rational perspective of experience, as an organic sequence of research. This arguments, over the study, describes how the experience is able to oxygenate a well-made thinking, as the concept created by Edgar Morin and expanded by Conceição Almeida. I argue that the experience as a path of investigative research allows one to ventures in the shadows of the unknown to access upper layers of reality. The experience is, therefore, an organic strategy for a well-made thinking - A nutritious mud that oxygenates, regulates, repairs and configures the quality of understanding. As a thread to discuss this ideas I've used my professional journey over a year and a half as a Natural Sciences' teacher on the Federal University of Rio Grande do Norte, where I could see how experiences helped on breaking a simplified understanding of the world. I chose to work with the research problems developed by 398 students over these three semesters. The problems were essential to the questioning of the phenomena that once seemed obvious or uninteresting, bringing out operational reasons and dynamics of the observed structures. Experience, in this sense, is the founder of dynamic thinking, as the need to deconstruct the phenomena's first impressions, assigning value and meaning to gestated knowledge.

Stroke is the leading cause of long-term disability among adults and motor relearning is essential in motor sequelae recovery. Therefore, various techniques have been proposed to achieve this end, among them Virtual Reality. The aim of the study was to evaluate electroencephalographic activity of stroke patients in motor learning of a virtual reality-based game. The study included 10 patients with chronic stroke, right-hande; 5 with left brain injury (LP), mean age 48.8 years (± 4.76) and 5 with injury to the right (RP), mean age 52 years (± 10.93). Participants were evaluated for electroencephalographic (EEG) activity and performance while performing 15 repetitions of darts game in XBOX Kinect and also through the NIHSS, MMSE, Fugl-Meyer and the modified Ashworth scale. Patients underwent a trainning with 45 repetitions of virtual darts game, 12 sessions in four weeks. After training, patients underwent reassessment of EEG activity and performance in virtual game of darts (retention). Data were analyzed using ANOVA for repeated measures. According to the results, there were differences between the groups (PD and PE) in frequencies Low Alpha (p = 0.0001), High Alpha (p = 0.0001) and Beta (p = 0.0001). There was an increase in alpha activation powers and a decrease in beta in the phase retention of RP group. In LP group was observed increased alpha activation potency, but without decrease in beta activation. Considering the asymmetry score, RP group increased brain activation in the left hemisphere with the practice in the frontal areas, however, LP group had increased activation of the right hemisphere in fronto-central areas, temporal and parietal. As for performance, it was observed a decrease in absolute error in the game for RP group between assessment and retention (p = 0.015), but this difference was not observed for LP group (p = 0.135). It follows then that the right brain injury patients benefited more from darts game training in the virtual environment with respect to the motor learning process, reducing neural effort in ipsilesionais areas and errors with the practice of the task. In contrast, patients with lesions in left hemisphere decrease neural effort in contralesionais areas important for motor learning and showed no performance improvements with practice of 12 sessions of virtual dart game. Thus, the RV can be used in rehabilitation of stroke patients upper limb, but the laterality of the injury should be considered in programming the motor learning protocol.

In general, men and women look for characteristics that can indicate improvement of their reproductive success in their romantic partners. However, partner choice is not only based on what the individual want in a partner, but he/she also takes into consideration how they perceive themselves in a determined environment, in a way that self-perception can change according to the context where the individual is inserted in. Besides the environment, self-esteem can be a factor that modifies romantic partner preferences and the way that people choose these partners for being able to influence how people evaluate themselves. Most of the studies that originate today’s universal standards in the study of romantic partner were conducted with undergraduate students, which may limit the coverage of the conclusions for contemplating people of the same educational level and probably also socioeconomic status (SES). The present research, held in Brazil, where the social inequality rate is high, and part in Canada, country with low social inequality, had as goal verifying romantic partners preferences and choices and self-evaluation as romantic partners in different educational level and SES. Men, mainly of low SES, tend to prioritize social status when looking for a romantic partner while the universal pattern is the preference for physical attractiveness, and women of low SES seem to be aware of this preference when expressing that social status is important for their self-perception. In addition, the results corroborate the influence of the context, selfesteem, and SES in the self-perception as a romantic partner, though the latter two appear to modulate how the is the influence of the context on participants’ perception. Moreover, this research also indicated that the preferences appear to represent the choices for the most important characteristics for each sex, being the other characteristics probably modulated by the quantity of available participants in the environment.

This study describes the development of a prototype to evaluate the potential of environments based on two-dimensional modeling and virtual reality as power substations learning objects into training environments from a central operation and control of power utility Cemig. Initially, there was an identification modeling features and cognitive processes in 2D and RV, from which it was possible to create frames that serve to guide the preparation of a checklist with assigning a metric weight for measuring cognitive potential learning in the study sites. From these contents twenty-four questions were prepared and each was assigned a weight that was used in the calculation of the metric; the questions were grouped into skill sets and similar cognitive processes called categories. Were then developed two distinct environments: the first, the prototype features an interactive checklist and your individual results. And, second, a system of data management environment for the configuration and editing of the prototype, and the observation and analysis of the survey results. For prototype validation, were invited to access the virtual checklist and answer it, five professionals linked to Cemig's training area. The results confirmed the validity of this instrument application to assess the possible potential of modeling in 2D and RV as learning objects in power substations, as well as provide feedback to developers of virtual environments to improve the system.

Objetivos: Avaliar as vias de referenciação dos doentes com estenoses carotídeas sintomáticas que foram operados na nossa instituição; estruturar os tempos de espera desde os primeiros sintomas neurológicos à data da cirurgia; identificar os fatores responsáveis pelos atrasos e criar estratégias que permitam reduzi-los. Material e métodos: Realizou-se um estudo observacional retrospetivo de todos os doentes com estenoses carotídeas sintomáticas submetidas a endarterectomia carotídea na nossa instituição entre 2011-2013. Foram identificadas as etapas essenciais no processo de referenciação dos doentes e foram colhidos dados referentes às datas do início dos sintomas, primeiro contacto médico, exames de imagem vascular, referenciação ao cirurgião, consulta de cirurgia vascular e da endarterectomia carotídea. O tempo decorrido entre o evento neurológico e a cirurgia foi calculado em dias e todos os atrasos identificados foram analisados detalhadamente. Resultados: A mediana do tempo de espera do evento neurológico à cirurgia foi de 27,5 dias (intervalo 7-581).Os maiores atrasos verificaram-se entre a data em que é colocada a indicação cirúrgica e a endarterectomia carotídea (mediana 9 dias; intervalo 1-349); na referenciação dos doentes à consultadecirurgia vascular (mediana 6,5 dias; intervalo 0-97)e entre o primeiro contacto médico e a realização dos exames de imagem vascular (mediana 6 dias; intervalo 1-71). Dos 60 doentes incluídos, apenas 21,7% foram operados nos primeiros 14 dias após o evento neurológico. O atraso foi significativamente menor nos doentes admitidos de forma urgente por transferência inter/intra-hospitalar (n=30; mediana 15 dias, intervalo 7-163) comparativamente aos doentes admitidos eletivamente pela consulta (n=30; mediana 86 dias, intervalo 13-581 dias) (p<0,0001).Discussão: Apesar da evidência atual, ainda existem atrasos significativos no processo de referenciação dos doentes com estenoses carotídeas sintomáticas. Estratégias direcionadas à redução destes atrasos poderão aumentar substancialmente a proporção de doentes submetidos a endarterectomia carotídea até 14 dias após o evento neurológico inicial.

The south region of the Rio Grande do Norte has been historically recognized as a place of old indian villages. Inhabitants of the edges of the Catu River, border between the cities of Canguaretama and Goianinha, the Eleotérios in the threshold of 21st century had passed to be seen and self recognized as "remaining indians" of the RN. Their ethnic mobilizations, when becoming public had placed to the intellectual and political fields an old question to be reflected on: the asseverations concerning the "indian disappearing" in the State. This item brings with it other implications. Accessed by a para-oficial indigenism, the Eleotérios had started to establish political relations with the Potiguara indians of the Baía da Traição/PB and the Indian Movement, feeling stimulated to produce and to reproduce forms of social differentiation. In this context, this research is worried about elucidating the process of construction of the ethnicity among the Eleotérios, percepted from the social relations and politics kept with the amplest society, into a particular historical situation involving sugar cane fields owners, proprietaries, militants, researchers, ambiental agencies. The effects of these political and social relations had been extended, making Eleotérios appear to the society as susceptible social actors to the specific policies for the aboriginal populations

The purpose of this research is to apprehend the perception that the ruling elite, especially the Presidents of the province of Rio Grande do Norte/Brazil, had about the potiguar city, that is, the urban localities existing in the province along the 19th century. By interweaving political, administrative, socioeconomic and spatial aspects, the study of this perception involves two distinct moments, which are also linked: a moment of apprehension of the city, that is, how the elite seizes, describes and criticizes the city; and, a second moment, which occurs simultaneously or after the first moment, of intervention in the city, in which the elite exposes its vision and projects for the city and for the territory. Rather than describing the potiguar city in itself, the research is an attempt to reveal how it was perceived along this process from a particular standpoint or discourse, official and elitist, which did not correspond necessarily or completely to what it was in reality. We tried to understand, always through the lens of the discourse, how the ruling elite perceived the potiguar city based on what their members thought about other urban realities, particularly of the advanced countries; how, within an integrated vision, this city was characterized in political, administrative, socioeconomic and spatial terms and how it consolidated itself along the period established for the research. Qualitative and historical in nature, this study was also methodologically developed based upon bibliographical and documental research. Given the fact that this research works with descriptions, comparisons and interpretations, it was necessary to make use of tools such as the discourse analysis in order to apprehend, as much as possible, what lay behind the words of the elite. The primary sources used were essentially the official documents produced by the Presidents of the province, as well as other documents written by top government officials and other members of the administration staff, all of them composing the so-called ruling elite of Rio Grande do Norte. Secondary sources were books and other publications, theses and dissertations, among others. The research made possible the identification of a certain perception of the potiguar city in the 19th century, which is certainly limited because it is grounded on a specific discourse - that of the political and administrative elite, but which, in spite of such a limitation, is still useful to understand the city and its evolution along the period established, among other noteworthy remarks

The present research concerns about outdoor s thermal comfort conditions in hot-humid climate cities, understanding that life quality is a result of the urban object s type built for the human being in an environment with specific climate and morphological characteristics. It is presented as object of study the correlation between the neighborhood Renascença II s microclimate in São Luis /MA-Brazil, hot-humid climate city, and its urban morphological changes. As well as the thermal comfort s satisfaction level of its outdoor users. The research has as general goal to diagnosis the way these transformations caused by the urbanization influence the Renascença II s microclimate, identifying critical spots of the studied area, in order to contribute with land use recommendations based on bioclimatic architecture concepts and supply bases to urban design decisions adequate to the São Luis climate. It is presented as theoretical bases the urban climate, its concepts and elements. After that, the thermal comfort conditioners and its prediction models of thermal comfort sensation in outdoor are presented. The predictive models are presented along with bioclimatic assessment methods. Finally the use of bioclimatic assessment as an effective tool to identify places that need changes or preservation in order to seek environment quality. The applied methodology was based on the studies of Katzschner (1997), complemented by Oliveira s (1988) and Bustos Romero s (2001) studies that suggest an analysis and evaluation of maps of topography, buildings floors, land use, green areas and land covering, in order to overlap their characteristics and identify climate variable s measurements points; then a quantitative analysis of the climate variables (air temperature and humidity, wind speed and direction) of the chosen points takes place. It was perceived that Renaissance II has no permanence areas as squares or parks, its outdoor has little vegetation and presets high land impermeability and built density levels. The majority of the people interviewed said that was comfortable in a range of air temperature between 27,28ºC and 30,71ºC. The elaboration of a neighborhood master plan is important, which defines strategies for improvement of the life quality of its inhabitants

Introdução: Terapias farmacológicas não têm conseguido um controle efetivo da dor na pessoa queimada nas três dimensões da dor aquando os cuidados à ferida. Assim, a Terapia da Realidade Virtual (TRV) baseia-se numa abordagem tecnológica que isola a pessoa do mundo real, visualizando apenas um ambiente virtual. Objetivo: Nesta Revisão Integrativa da Literatura pretende-se: identificar se a aplicação da TRV reduz a dor nas três dimensões aquando os cuidados à ferida; verificar em que medida a aplicação da TRV reduz a dor em cada uma das três dimensões de dor; verificar se a aplicação da TRV permite a redução de administração da analgesia opioide. Método: Efetuou-se pesquisa em motores de busca online, num período temporal de dez anos por meio de descritores e critérios de inclusão predefinidos. Definiu-se como questão de investigação "Qual é a eficácia da aplicação da Terapia da Realidade Virtual na redução da dor nos cuidados à ferida à pessoa numa unidade de queimados?". Na consecução deste trabalho, teve-se como método os Sete Passos do Cochrane Handbook, sendo incluídos seis artigos. Resultados: Pela análise dos resultados, evidencia-se a redução da dor nas três dimensões, na maioria dos estudos, quando associada a TRV a terapias farmacológicas. Conclusões: Propõem-se mais estudos randomizados controlados para definir os benefícios da TRV, comparativamente com terapias não farmacológicas menos dispendiosas.
