Interação gestual em ambiente residencial: estudo, concepção e desenvolvimento

Control and automation of residential environments domotics is emerging area of computing application. The development of computational systems for domotics is complex, due to the diversity of potential users, and because it is immerse in a context of emotional relationships and familiar construction. Currently, the focus of the development of this kind of system is directed, mainly, to physical and technological aspects. Due to the fact, gestural interaction in the present research is investigated under the view of Human-Computer Interaction (HCI). First, we approach the subject through the construction of a conceptual framework for discussion of challenges from the area, integrated to the dimensions: people, interaction mode and domotics. A further analysis of the domain is accomplished using the theoretical-methodological referential of Organizational Semiotics. After, we define recommendations to the diversity that base/inspire the inclusive design, guided by physical, perceptual and cognitive abilities, which aim to better represent the concerned diversity. Although developers have the support of gestural recognition technologies that help a faster development, these professionals face another difficulty by not restricting the gestural commands of the application to the standard gestures provided by development frameworks. Therefore, an abstraction of the gestural interaction was idealized through a formalization, described syntactically by construction blocks that originates a grammar of the gestural interaction and, semantically, approached under the view of the residential system. So, we define a set of metrics grounded in the recommendations that are described with information from the preestablished grammar, and still, we conceive and implement in Java, under the foundation of this grammar, a residential system based on gestural interaction for usage with Microsoft Kinect. Lastly, we accomplish an experiment with potential end users of the system, aiming to better analyze the research results

DERSU UZALA Hibridação Homem-Natureza

Esta disertación explora de qué forma las hibridaciones entre ser humano y ambientes naturales no urbanos contribuyen a configurar las estrategias de atención, de construcción de conocimiento y de interacción con el mundo del sujeto y cómo, recursivamente, las actitudes perceptivo-cognitivas y las maneras de acercarse a lo real, de imputar sentido a los fenómenos y de interactuar con el ambiente practicadas por el sujeto condicionan y contribuyen a definir las hibridaciones entre humanos y no humanos. Lo que guía esa exploración es el concepto de híbrido que, inspirándome en Bruno Latour (2008), concibo como una asociación entre elementos sin características inherentes, compenetrados, que se redefinen, recrean e reconfiguran recíprocamente. Utilizo como operadores cognitivos una narrativa literaria y una cinematográfica: el libro autobiográfico Dersu Uzala del escritor y explorador ruso Vladimir Klavdievich Arseniev (1872-1930), publicado por primera vez en 1923, y la película homónima del director japonés Akira Kurosawa (1910-1998), lanzada en 1975. Estas obras reconstruyen tres expediciones realizadas por Arseniev a principios del siglo XX en la región siberiana del Ussuri que tuvieron como guía al cazador nómada de etnia gold Dersu Uzala, con quien el escritor construyó una profunda amistad. La elección de hacer dialogar en el mismo plan a dos modos complementares de conocimiento, arte y ciencia, se fundamenta en la concepción de Edgar Morin (2003b) de la literatura y el cine como escuelas de vida y de complejidad humana y en la visión de Claude Lévi- Strauss (2007) del arte como modelo reducido que favorece una mirada más abarcadora sobre los fenómenos. Inicialmente, pongo en relación mi investigación con los trabajos de Silmara Lídia Marton (2008) y Samir Cristino de Souza (2009), que analizaron las estrategias de construcción de conocimiento y de interacción con el mundo de un habitante de la Laguna de Piató (Municipio de Assú, Estado de Rio Grande do Norte, Brasil), Francisco Lucas da Silva, y muestro algunas analogías entre estas y las de Dersu Uzala, ambas productos de determinadas hibridaciones con el ambiente. A continuación, exploro las implicaciones cognitivas de la amistad de Arseniev con el cazador gold, metáfora/encarnación del diálogo posible entre saberes de matrices diferentes. En un tercer momento, dialogando con pensadores que se interrogaron sobre el trinomio hombre-naturaleza-representaciones y con las narrativas de Arseniev (1997) y Kurosawa (1975), reflexiono sobre las ideas de híbrido, de humano y no humano, de vivo y no vivo, de proximidad y distancia del sujeto con respecto a otros sistemas de lectura del mundo, de relación directa y mediada con lo real, de ambientes naturales urbanos y no urbanos. A seguir, incursiono en el libro de Arseniev y en el largometraje de Kurosawa intentando identificar qué factores más contribuyeron para configurar las estrategias de conocimiento y de interacción con el ambiente manifestadas por el explorador y por el cazador gold y, recursivamente, de qué forma esas estrategias contribuyeron a definir sus hibridaciones con el ambiente siberiano. Por último, a partir de las reflexiones tejidas a lo largo del trabajo, me interrogo sobre lo que ellas pueden decirnos sobre nuestra forma de interactuar con la naturaleza no humana y sobre el diálogo entre distintas formas de percibir, conocer y relacionarse con el mundo

Padrão de atividades e de interações sociais de animais juvenis em dois grupos selvagens de Callithrix jacchus

The juvenile period represents the developmental phase between weaning and sexual maturity. Weaning occurs when the youngster does not receive direct care from the caretakers anymore. Individuals in the species Callithrix jacchus live in groups composed by the reproductive pair and successive twin sets. Cooperative care is the rule. Infants are weaned early, and from then on, food is provided by the adults in the group. These animals present high levels of social interactions, through play, grooming and social contact. During infant age, the twin becomes the main partner. There are few studies about the juvenile period, especially on Callithrix gender. The objective of this study was describing the pattern of activities and social interactions of four sets (one single and three twin sets) during juvenile phase in two Callithrix jacchus groups. We used instantaneous and continuous focal sampling for juveniles and scan sampling for adults behavioral recordings. Juveniles presented the same behavioral pattern as the adults relating the activity budget, in particular, foraging along the months. The composition of the diet was the same as that of the adults. Food transfer ended along the juvenile period. Social play as much as grooming were important socializing activities for the juveniles. The young individuals in the group were the main partners in social play, specially the twin. Adults were the main partners in grooming interactions. Scent marking differed between twins in the male/female sets, the female presenting the highest levels of marking. The juveniles were independent from adults in foraging activity. Social interaction varied according to group composition, but in general, interacted more with the twin and with the youngsters (infants and subadults), except in grooming. Even presenting many similarities, juveniles showed some differences between genders, which indicates the differentiation in behavior towards reproductive strategies early in the juvenile period

Recuperação e purificação de proteínas do soro de queijo tipo coalho usando cromatografia de troca iônica e interação hidrofóbica em leito na forma expandida

Expanded Bed Adsorption plays an important role in the downstream processing mainly for reducing costs as well as steps besides could handling cells homogenates or fermentation broth. In this work Expanded Bed Adsorption was used to recover and purify whey proteins from coalho cheese manufacture using Streamline DEAE and Streamline SP both ionic resins as well as a hydrophobic resin Streamline Phenyl. A column of 2.6 cm inner diameter with 30 cm in height was coupled to a peristaltic pump. Hydrodynamics study was carried out with the three resins using Tris-HCl buffer in concentration of 30, 50 and 70 mM, with pH ranging from 7.0 to 8.0. In this case, assays of the expansion degree as well as Residence Time Distribution (RTD) were carried out. For the recovery and purification steps, a whey sample of 200 mL, was submitted to a column with 25mL of resin previously equilibrated with Tris/HCl (50 mM, pH 7.0) using a expanded bed. After washing, elution was carried out according the technique used. For ionic adsorption elution was carried out using 100 mL of Tris/HCl (50 mM, pH 7.0 in 1M NaCl). For Hydrophobyc interaction elution was carried out using Tris/HCl (50 mM, pH 7.0). Adsorption runs were carried out using the three resins as well as theirs combination. Results showed that for hydrodynamics studies a linear fit was observed for the three resins with a correlation coefficient (R2) about 0.9. In this case, Streamline Phenyl showed highest expansion degree reaching an expansion degree (H0/H) of 2.2. Bed porosity was of 0.7 when both resins Streamline DEAE and Streamline SP were used with StremLine Phenyl showing the highest bed porosity about 0.75. The number of theorical plates were 109, 41.5 and 17.8 and the axial dipersion coefficient (Daxial) were 0.5, 1.4 and 3.7 x 10-6 m2/s, for Streamline DEAE, Streamline SP and Streamline Phenyl, respectively. Whey proteins were adsorved fastly for the three resins with equilibrium reached in 10 minutes. Breakthrough curves showed that most of proteins stays in flowthrough as well as washing steps with 84, 77 and 96%, for Streamline DEAE, Streamline SP and Streamline Phenyl, respectively. It was observed protein peaks during elution for the three resins used. According to these peaks were identified 6 protein bands that could probably be albumin (69 KDa), lactoferrin (76 KDa), lactoperoxidase (89 KDa), β-lactoglobulin (18,3 KDa) e α-lactoalbumin (14 KDa), as well as the dimer of beta-lactoglobulin. The combined system compound for the elution of Streamline DEAE applied to the Streamline SP showed the best purification of whey proteins, mainly of the α-lactoalbumina

Efeitos da interação dipolar na nucleação de vórtices em nano-cilindros magnéticos

The effect of confinement on the magnetic structure of vortices of dipolar coupled ferromagnetic nanoelements is an issue of current interest, not only for academic reasons, but also for the potential impact in a number of promising applications. Most applications, such as nano-oscillators for wireless data transmission, benefit from the possibility of tailoring the vortex core magnetic pattern. We report a theoretical study of vortex nucleation in pairs of coaxial iron and Permalloy cylinders, with diameters ranging from 21nm to 150nm, and 12nm and 21nm thicknesses, separated by a non-magnetic layer. 12nm thick iron and Permalloy isolated (single) cylinders do not hold a vortex, and 21nm isolated cylinders hold a vortex. Our results indicate that one may tailor the magnetic structure of the vortices, and the relative chirality, by selecting the thickness of the non-magnetic spacer and the values of the cylinders diameters and thicknesses. Also, the dipolar interaction may induce vortex formation in pairs of 12nm thick nanocylinders and inhibit the formation of vortices in pairs of 21nm thick nanocylinders. These new phases are formed according to the value of the distance between the cylinderes. Furthermore, we show that the preparation route may control relative chirality and polarity of the vortex pair. For instance: by saturating a pair of Fe 81nm diameter, 21nm thickness cylinders, along the crystalline anisotropy direction, a pair of 36nm core diameter vortices, with same chirality and polarity is prepared. By saturating along the perpendicular direction, one prepares a 30nm diameter core vortex pair, with opposite chirality and opposite polarity. We also present a theoretical discussion of the impact of vortices on the thermal hysteresis of a pair of interface biased elliptical iron nanoelements, separated by an ultrathin nonmagnetic insulating layer. We have found that iron nanoelements exchange coupled to a noncompensated NiO substrate, display thermal hysteresis at room temperature, well below the iron Curie temperature. The thermal hysteresis consists in different sequences of magnetic states in the heating and cooling branches of a thermal loop, and originates in the thermal reduction of the interface field, and on the rearrangements of the magnetic structure at high temperatures, 5 produce by the strong dipolar coupling. The width of the thermal hysteresis varies from 500 K to 100 K for lateral dimensions of 125 nm x 65 nm and 145 nm x 65 nm. We focus on the thermal effects on two particular states: the antiparallel state, which has, at low temperatures, the interface biased nanoelement with the magnetization aligned with the interface field and the second nanoelement aligned opposite to the interface field; and in the parallel state, which has both nanoelements with the magnetization aligned with the interface field at low temperatures. We show that the dipolar interaction leads to enhanced thermal stability of the antiparallel state, and reduces the thermal stability of the parallel state. These states are the key phases in the application of pairs of ferromagnetic nanoelements, separated by a thin insulating layer, for tunneling magnetic memory cells. We have found that for a pair of 125nm x 65nm nanoelements, separated by 1.1nm, and low temperature interface field strength of 5.88kOe, the low temperature state (T = 100K) consists of a pair of nearly parallel buckle-states. This low temperature phase is kept with minor changes up to T= 249 K when the magnetization is reduced to 50% of the low temperature value due to nucleation of a vortex centered around the middle of the free surface nanoelement. By further increasing the temperature, there is another small change in the magnetization due to vortex motion. Apart from minor changes in the vortex position, the high temperature vortex state remains stable, in the cooling branch, down to low temperatures. We note that wide loop thermal hysteresis may pose limits on the design of tunneling magnetic memory cells

Generosidade e cooperação de crianças monitoradas e não monitoradas: a interação entre a condição socioeconômica e o ambiente escolar

Studies have shown that a person's socioeconomic status (SES) and the environment in which they are inserted modulate their pro-sociality. While children studying in schools with a more affluent student body tend to be more generous, adults with high SES in both real and experimental situations tend to be more selfish, greedy and individualistic. Another factor that influences pro-sociality is monitoring. When we do something under the supervision of another person, we tend to be more generous and cooperative, compared to situations in which no one is watching, even if the "observer" is a drawing of eyes. This monitoring effect occurs in both adults and children. To date, no studies have investigated whether the SES and the environment influence the pro-sociality of the children. There have also been no studies on how the monitoring effect might be influenced by SES and the environment (in this case, whether the environment is a public or private school). Given this context, our main objective was to investigate whether the generosity and cooperation of monitored and unmonitored kids is modulated by these factors. To this end, we did eight matches of the public goods, under monitoring and control conditions, with 249 children from the ages of 7 to 10 years enrolled in public and private schools in Natal, state of Rio Grande do Norte (Brazil). The SES of each child's family was assessed according to the Economic Classification Criterion of Brazil (2013). Contrary to our predictions, SES, school environment and experimental conditions did not significantly influence cooperation and generosity behavior when analyzed separately. We discuss whether the influences of resource and experimental design adopted for the current study and the historical and economic conditions of Brazil might explain these observations. Interestingly, when SES and school environment were analyzed together, an effect of monitoring on generosity and cooperation was detected. More specifically, monitoring had the effect of decreasing generosity among children with greater SES in private schools; and increased cooperation among children with greater SES in public schools. These results suggest that there is an influence of monitoring on the pro-sociality of children in relation to their SES and acquaintanceship environments. We argue that these observations may be explained by different preoccupations with reputation, according to the environment in which a child is inserted.

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Acessibilidade no ambiente escolar: reflexões com base no estudo de duas escolas municipais de Natal-RN

This work was originated through the results of the analysis of the services for the needs of people with disabilities that were permitted by the physical space of two schools of the municipality of Natal/RN. The general objective/goal was to subsidize the elaboration of alternatives for the planning of environments that could be used by any person. The study used the empirical research through the adoption of a multimethod approach including: (i) technical visits oriented by the NBR 9050, (ii) contact with users that have reduced mobility (visually impaired and wheelchair or crutch users) through escorted travels and interviews, and (iii) interview with school managers. The evidence from the research, even though with significant development of laws that guarantee people with disabilities their right to citizenship, the physical environment of our schools still present with many obstacles that prevent the mobility of people with disabilities which proves their lack of readiness to accommodate them. Therefore, the actions taken to address the accessibility has been the adoption of temporary solutions that makes the adaptation more difficult, adds obstacles and reinforces the undesirable segregation, however still very present in our society. Finally, there is the indication that in order to achieve the spatial configuration that promotes social contact and integration in between the persons with different physical status, it is necessary to completely comprehend the activities developed in each space, from the conception of the equipment to the individual learning needs, having in mind creating environments that stimulates the execution of the tasks in an independent manner without the assistance of others. The inclusion regarding attention to accessibility in the decision making process, directed to the arquitectural and urban project, would decrease the constant need to redevelop and adapt spaces, and should be definitely incorporated as an important component in the production of space

Estrutura e dinâmica do fitoplânctone bacterioplâncton em cultivos de camarão no Rio Grande do Norte-Brasil: impacto sobre o ambiente natural

This work aimed to study the structure and dynamic of Phytoplankton and Bacterioplankton in a complete cycle of shrimp cultivation (Litopenaeus vannamei) and determine the environmental factors responsible for the structural changes of these communities. The study was realized in a saltwater shrimp farm (Macaíba, RN), between September/2005 and February/2006, and in a freshwater shrimp farm (Ceará Mirim, RN), between May/2007 and September 2007. The samplings were collected weekly in saltwater farm and every fifteen days in freshwater farm. Total phosphorus, chlorophyll a and environmental parameters (pH, dissolved oxygen, salinity, temperature, depth and water transparency) were measured. Qualitative and quantitative analysis of the phytoplankton and bacterioplankton were carried out. The Shannon-Wiener ecologic indexes of diversity and the Pielou equitability indexes were calculated to the phytoplankton. Bacterial density was determined by epifluorescence microscopy. The data were statistically analyzed by Pearson correlation and t-Test. Chlorophycea were predominat in salt water and in the captation/drainage point (24 to 99%). Diatoms had higher wealth. The species Choricystis minor had the highest occurrence (100%) and dominance (90-100%), thus showing its adaptation to the high temperatures, salinity and low water transparency conditions. Filamentous Cyanobacteria like Oscillatoria sp., Pseudoanabaena sp. and Phormidium sp. had constant levels. The negative correlation between chlorophycea and water transparency, and the positive correlation between chlorophyll a and salinity, showed that the phytoplankton was well adapted to the low transparency and to the high salinity. The bacterioplankton was negatively correlated with the total phosphorus and salinity. In freshwater, Cyanobacteria were predominant (>80%), presenting some producers of toxins species like Microcystis sp., Aphanizomenon sp., Cylindrospermopsis raciborskii e Anabaena circinalis. Cyanobacterial density and total phosphorus and chlorophyll a concentrations exceeded the maximum value allowed by legislation. The means of total phosphorus varied from 264 to 627 Wg.L-1 and the means of chlorophyll a oscillated between 22 and 182 Wg.L-1. The phytoplankton species were selected by low availability of the light, high pH, temperature and high availability of total phosphorus. The bacterioplankton showed high densities (5,13 x 107 to 8,50 x107 Bac.mL-1). The studied environments (ponds and rivers) presented a high level of trophic state based on the high concentrations of chlorophyll a and total phosphorus and cyanobacteria dominance. The composition of species in the ponds and rivers was similar, as well as high concentrations of total phosphorus and chlorophyll a, highlighting the pollution caused by the discharges of the farms in natural environment

Interação de microorganismos na solubilização de fósforo e potássio de rochas para produção de biofertilizantes

he present model of agriculture is based on intensive use of industrial inputs, due to its rapid response, but it brings harmful consequences to the environment, and it is necessary the use of modern inputs. And an alternative is the use of rock biofertilizers in agriculture, a product easy to use, with higher residual effect and does not harm the environment. The objective of study was to evaluate the inoculation and co-inoculation of different microorganisms in the solubilization of rock phosphate and potash ground microbial evaluating the best performance in the production of biofertilizers comparing with rocks pure in soil chemical properties and, verify effect of inoculation of the bacterium Paenibacillus polymyxa in the absorption of minerals dissolved in the development of cowpea (Vigna unguiculata [L.] Walp.). The first bioassay was conducted in Laboratory (UFRN) for 72 days in Petri dishes, where the rock powder was increased by 10% and sulfur co-inoculated and inoculated with bacterial suspension of Paenibacillus polymyxa grown in medium tryptone soy broth, Ralstonia solanacearum in medium Kelman, Cromobacterium violaceum in medium Luria-Bertani and Acidithiobacillus thiooxidans in medium Tuovinen and Kelly,and fungi Trichoderma humatum and Penicillium fellutanum in malt extract. Every 12 days, samples were removed in order to build up the release curve of minerals. The second bioassay was conducted in a greenhouse of the Agricultural Research Corporation of Rio Grande do Norte in experimental delineation in randomized block designs, was used 10 kg of an Yellow Argissolo Dystrophic per pot with the addition of treatments super phosphate simple (SS), potassium chloride (KCl), pure rock, biofertilizers in doses 40, 70, 100 and 200% of the recommendation for SS and KCl, and a control, or not inoculated with bacteria P. polymyxa. Were used seeds of cowpea BRS Potiguar and co-inoculated with the bacterial suspension of Bradyrhizobium japonicum and P. polymyxa. The first crop was harvested 45 days after planting, were evaluated in the dry matter (ADM), macronutrients (N, P, K, Ca, Mg) and micronutrients (Zn, Fe, Mn) in ADM. And the second at 75 days assessing levels of macro end micronutrients in plants and soil, and the maximum adsorption capacity of P in soil. The results showed synergism in co-inoculations with P. polymyxa+R. solanacearum and, P. polymyxa+C. violaceum solubilizations providing higher P and K, respectively, and better solubilization time at 36 days. The pH was lower in biofertilizers higher doses, but there was better with their addition to P at the highest dose. Significant reduction of maximum adsorption capacity of phosphorus with increasing dose of biofertilizer. For K and Ca was better with SS+KCl, and Mg to pure rock. There was an effect of fertilization on the absorption, with better results for P, K and ADM with SS+KCL, and N, Ca and Mg for biofertilizers. Generally, the P. polymyxa not influence the absorption of the elements in the plant. In treatments with the uninoculated P. polymyxa chemical fertilizer had an average significantly higher for weight and number of grains. And in the presence of the bacteria, biofertilizers and chemical fertilizers had positive values in relation to rock and control. The data show that the rocks and biofertilizers could meet the need of nutrients the plants revealed as potential for sustainable agriculture

Interação competitiva do zinco e ferro após administração oral e venosa de zinco em crianças eutróficas

The aim of this study was to assess the acute and chronic effects of zinc in serum iron profile of children aged 6-9 years in relation to nutritional status and dietary intake. The study participants were 11 children regardless of sex, aged 6-9 years. They were selected from three public schools of the city of Natal, Brazil. Body mass index was used to assess nutritional status. In order to determine the patterns of childhood growth and ideal weight we used the standards of the World Health Organization. The dietary intake assessment was based on information from a three-day prospective food survey. The variables were energy intake, protein, lipids, carbohydrates, fiber, calcium, iron and zinc. All children underwent an intravenous administration of zinc (IVAZn) before and after oral administration of zinc (OAZn) (5 mg Zn / day) for three months. We measured serum iron, hematocrit, hemoglobin and total protein, before and after the use of oral zinc. The analysis of hematocrit, hemoglobin and total protein was performed using standard methods of clinical laboratory. Zinc levels and serum iron were measured by atomic absorption spectrophotometry. The project was evaluated and approved by the Ethics in Research Committee of Federal University of Rio Grande do Norte. Results: All children had normal weight. The consumption of energy, fat, fiber, calcium and iron were below recommended levels. However, the levels of protein and carbohydrates were high. Protein and zinc increased significantly after OAZn. Carbohydrate and protein were elevated in the blood. After OAZn, both protein and zinc increased, being statistically significant. Conclusion: The potential inhibitory effect of physiological or pharmacological doses of zinc on the profile of serum iron was observed in children with healthy weight and aged between 6 and 9 years. This negative effect of zinc did not affect the levels of hematocrit or hemoglobin, and therefore did not cause anemia. This was a multidisciplinary study, involving researchers from medicine, nutrition and pharmacy. This met the requirements of multidisciplinarity of the Post Graduate Program in Health Sciences of Federal University of Rio Grande do Norte.

Atrás das grades: redes sociais, habitus e interação social no sistema carcerário do RN

Esta tesis trata de discutir y entender los diversos tipos de redes sociales y formas de interacción social presentes en el sistema penitenciario de Rio Grande do Norte. Nuestro problema se basa en un incremento significativo en las tasas de encarcelamiento y la prisión en Brasil y el mundo en los últimos diez años. Asimismo, la aparición del crimen organizado ya, en cierta medida, el control de las prisiones brasileñas, como el Comando Vermelho (CV) y el Primeiro Comando da Capital (PCC), una consecuencia directa de las terribles condiciones de las prisiones de Brasil y aumento de la violencia y el crimen en nuestro país. Para resolver el problema, se optó por utilizar las categorías de análisis de Michel Foucault (prisión y la disciplina), Pierre Bourdieu (habitus y campo), Ervirng Goffman (institución total, de interacción, de fachada y de equipo) y Mark Granovetter, Ricardo Abramovay e João Peixoto, entre otros, la nueva sociología económica (Redes, nodos y lazos) como principal apoyo. También construyó una revisión histórica de la cárcel en Brasil y Rio Grande do Norte hasta llegar al objeto. Esto, en términos de investigación cualitativa, se sumergió en el mundo de las prisiones Dr. Francisco Nogueira Fernandes, conocido como Penitenciario de Alcaçuz, ubicado en el municipio de Nísia Bosque, Rio Grande do Norte. Penitenciaría del Estado de origen, las casas de Alcaçuz seiscientos cuarenta y tres reclusos, divididos en cinco pabellones, un total de ciento cuarenta y siete células. Mediante la observación sistemática y la entrevista cualitativa s semi-estructurada como las principales fuentes de recopilación de datos, hemos tratado de explicar el universo que acabamos de analizar por las Ciencias Sociales. Nos dimos cuenta de que, para cumplir con la escena nacional, regaliz viola de manera flagrante lo que se denomina en la Constitución de 1988 y LEP (Ley de Ejecución Penal), sin tener en cuenta los derechos de los individuos a una porción de una oración con un mínimo de dignidad. Se ha demostrado que las personas que permean el universo proviene de un ambiente de la prisión, la sociabilidad violenta, sedo también tienen un habitus precario. La prisión, espacio disciplinario y un tipo específico de interacción social marcada por el control, contribuye a la profundización de habitus, pero que muestra que no es también como un espacio cerrado en absoluto, sino un lugar donde penetran las redes y dinámicas muy social. Al mismo tiempo, se encontró que más de la presencia de "grupos organizados" es el espacio en las cárceles para la interacción social y las redes sociales que pasan dentro y fuera de su espacio

Biologia populacional comparada de duas espécies de heliconius (Lepidoptera: Nymphalidae) em um ambiente sazonal de floresta atlântica do nordeste brasileiro

Tropical environments often face strong seasonal variations in climate, such as alternate periods of dry and rain, that may often be important influence in the annual X the organisms lives. Here we assess how population dynamics of two butterfly species (Heliconius erato and Heliconius mepomene) respond to environmental and seasonal variations. A mark-release-recapture study carried out in an Atlantic forest reserve, 15 Km from Natal, Rio Grande do Norte, Brazil, for 3 years, during the dry and rainy season, with three visits weekly done. Information such as species, wing lenght, site of capture, pollen load and phenotype (number of spots) (in H. erato only) were noted for each capture. Seasonal variation exists in capture rates of the two species, with great capture rates during the rainy season. Despite finding differences in the mean density of individuals of the two species among the different collection areas, this difference was only significant between floodplain and central areas, and no influence of seasonality was observed in the mean density between the areas. Seasonality in wing size was only observed for H. erato, with larger wings during the rainy season. Females carried larger pollen loads than males both species, but species were similar. Only males differed seasonally, with larger pollen loads during the rainy season. The distribution of the number of wing spots did not vary between the dry and rainy seasons, and the number of spots in males and females was similar. Therefore, we conclude that there was a strong influence of seasonal variation in the population dynamic of the two Heliconius species, as well as in several aspects of their biology

Satisfação da equipe de enfermagem do serviço de atendimento móvel às urgências (SAMU) no ambiente de trabalho

Descriptive exploratory study, prospective with quantitative approach, performed on the Medical Regulation Central of SAMU/Natal, aiming to identify the level of professional satisfaction of the members of the nursing team working at SAMU/Natal; and verify the degree of importance attributed by the professionals to each of the components Professional Satisfaction: autonomy, interaction, professional status , work requirements, organizational rules and remuneration. The population was of 60 professionals, with data collected from january to february 2005. We used an instrument translated and validated by Lino (1999) to the portuguese language, the Professional Satisfaction Rate (PSR). The results demonstrate that there was a slight predominance of the female gender (54,9%); aged between 36 and 45 years old (60,8%); married (58,8%), 82,4% with children, 30,8% aged between 05 and 09. Regarding formation, we observed that 78,4% were nursing technicians and 21,6% nurses, formed for 11 to 15 years (17,5%). From the 11 nurses, 09 (81,8%) informed they have specialization, 29,4% of the team has been working for 11 to 15 years on the urgency area, 58.8% works for more than 02 years on SAMU, 72,6% of the team members have fixed work schedules. There was homogeneity on the work shifts: 41,2% on the day shift and 53% on the night shift. Regarding the reason to be working on SAMU, 64% chose to work in the service, and among these 76,3% predominantly perform direct care to the patients, 96,1% like and are satisfied to work in the service. Regarding the remuneration, 90,9% informed they receive 05 to 10 minimum wages; 70% of the technicians informed they receive -2 to 05 minumum wages, 50,1% informed they receive no additional benefit. The analysis of PSR through Cronbach s Alpha Coeficient resulted on the value of 0,94 and through Kendall s Tau Coeficient on 0,87, demonstrating to be a trustworthy instrument to measure the level of professional satisfaction of the SAMU nursing team, in our environment. As for the level of importance attributed to the components of professional satisfaction, we indentified that the nursing team considered the Autonomy component as the most important, followed by the component Remuneration, Interaction, Work Requirements, Work Requirements, Organizational Rules and Professional Status .

Relações interpessoais no ambiente de trabalho da equipe de enfermagem: uma ação comunicativa

The current study strives to address the interpersonal relationships of the nursing team from the perspective of the communicative action, by contributing to the health work process. It aims to analyze the interpersonal relationships of the nursing team in its work environment. This is a descriptive study with a qualitative approach. Data collection wal held from interviews, guided by a script with open questions. The study was conducted at a state hospital in the city of Natal/RN/Brazil. The research subjects were the workers of the nursing team, including nurses, nursing technicians and nursing assistants, totaling 16 subjects. The capture of information was performed in April 2012. The project was approved by the Ethics Research Committee, under CEP/UFRN protocol n. º 262/11 and Certificate of Presentation for Ethical Consideration n. º 0289.0.051.000-11. The analysis was performed from the categories that emerged from the research through a dialogue with the authors studied in the theoretical framework of the Theory of communicative action , by Jürgen Habermas, as well as The changing in the world of work, by Ricardo Antunes, and Characterization of the team , by Marina Peduzzi. The outocomes point out that the interpersonal relationship of the nursing team is very troubled, with no interaction among the individuals involved in this process, among themselves and with other health professionals. We have developed a particular concept about team, which is comprised of three essential elements: multiplicity of individuals, common objective and heterogeneity. In the studied environment, it was realized the existence of grouping teams. The interpersonal relationship of the nursing can be a facilitator or an obstacle in the workplace in such a way that causes positive or negative consequences, both to the health workers, and to the sicks. In this context, the interviewees have intensified their viewpoints with regard to the weaknesses that permeate the nursing relationship, by pointing them more frequently than the strengths. The work conditions have signaled a failing situation, which is evidenced by the constant improvisation process before the lack of human and material resources, low wages, deficit in recognizing the nursing worker, and physical and emotional wear, by creating a professional exhaustion. The devaluation of the worker also became a strong factor for this study, because it was characterized a reason of job dissatisfaction, due to the lack of valuation policies, which should be prepared by the institution or, even, they are unknown by the worker itself. The worker participation in the design of these policies has emerged as a relevant factor. The poor work conditions lead the worker to a process of professional demotivation and dissatisfaction, by causing the feeling of devaluation within its work environment. Hence, it was found in this research that the lack of communication leads to situations of inadequate interpersonal relationships, which are creators of an unsuitable environment for the performance of the nursing team
