Comparação e mobilidade, equilíbrio corporal e desempenho muscular segundo a auto-eficácia para quedas em idosas

The aging process modifies various systems in the body, leading to changes in mobility, balance and muscle strength. This can cause a drop in the elderly, or not changing the perceived self-efficacy in preventing falls. Objective: To compare the mobility, body balance and muscle performance according to self-efficacy for falls in community-dwelling elderly. Methods: A cross-sectional comparative study with 63 older (65-80 years) community. Were evaluated for identification data and sociodemographic, cognitive screening using the Mini Mental State Examination (MMSE), effective for the fall of Falls Efficacy Scale International Brazil (FES-I-BRAZIL), Mobility through the Timed Up and Go Test , the balance Berg Balance Scale (BBS) and the Modified Clinical Test tests of Sensory Interaction on Balance (mCTSIB), tandem walk (TW) and Sit to Stand (STS) of the Balance Master® System. Finally, muscle performance by using isokinetic dynamometry. Statistical analysis was performed Student t test for comparison between groups, with p value ≤ 0.05. Results: Comparing the elderly with low-efficacy for falls with high-efficacy for falls, we found significant differences only for the variable Timed Up and Go Test (p = 0.04). With regard to data on balance tests were significant differences in the speed of oscillation firm surface eyes open modified Clinical Test of Sensory Interaction on Test of Balance (p = 0.01). Variables to isokinetic dynamometry were no significant differences in movement knee extension, as regards the variables peak torque (p = 0.04) and power (p = 0.03). Conclusion: The results suggest that, compared to older community with low-and high-efficacy for falls, we observed differences in variables related to mobility, balance and muscle function

Entre a ausência declarada e a presença reclamada: a identidade potiguar em questão

How do the identities of a people build themselves? How do the geographic clippings influence the representations of some social groups, when they define themselves or when they are defined, for example, as people from Pernambuco, Rio Grande do Sul, Paraíba, Rio de Janeiro, Ceará, Bahia? What symbolic elements, contests and benefits are involved in these processes of identity construction? By taking the discussions about potiguar people as the theme of this research, we intend to discuss about the displacements, the impasses in their representations that usually represent him as a being who he is not, constantly seduced by the enchantments of the other, by the values that come from outside. Thus, from the Rio Grande do Norte space, we investigated, in various contexts, since the last three decades of the nineteenth century to the current days, how the space identities have been used as strategy, by various characters, in attempt to build and/or to define representations that characterize and single potiguares out, in the face of other beings of the nation

Guerra e identidade: um estudo da marcialidade no Heimskringla

The goal of our dissertation is to study how the Scandinavian writings produced a Norwegian identity of warlike ideals in a compilation of Icelandic sagas known as Heimskringla and has parts of its content focused on storytelling about a troubled time of Scandinavian monarchies rising between the 8th and 11th centuries, which is called the Viking Age. The Heimskringla, also known as The Circle of the World is a set of writings based on Icelandic oral memory about the Norwegian kings and the conception of a Norwegian territory. While we investigated the relationship between the members of royalty, their companions and the Scandinavian people, we delineate the relationship between memory, identity and war. Our study points out how the Scandinavian war produces, in its storytelling, proper spaces, in socio-political relations among the participants, in the organization of its conflicts or the location of war activities, where places are transformed into essential points in these narratives. The war is both a place of identity statements and a space of practices, necessary for the strengthening of royal power

Influência da auto seleção à luz no ritmo circadiano de atividade motora em Callithrix Jacchus

Marmosets, Callithrix jacchus, are strictly diurnal animals. The motor activity rhythmicity is generated by the circadian timing system and is modulated by environmental factors, mainly by photic stimuli that compose the light-dark cycle. Photic stimuli can reset the biological oscilators changing activity motor pattern, by a mechanism called entrainment. Otherwise, light can act directly on expressed rhythm, without act on the biological oscillators, promoting the masking. Thus, photic stimuli can synchronize the circadian activity rhythm (CAR) by two distinct mechanisms, acting isolated or at a combined way. Among the elements that can influence photic synchronization, the duration and time of photic exposure is pointed out. If in the natural environment the marmoset can choose places of different intensity illumination and is synchronized to light-dark cycle (LD), how the photic synchronization mechanism can be evaluated in laboratory by light self-selection? With objective to response this question, four adult male marmosets were studied at two conditions: with and without sleeping box. The animals were submitted to a LD cycle (12:12/ 350:2 lx) and constant light (LL: 350 lx) conditions in individual cages with an opaque sleeping box, that permitted the light self-selection. At the room, the temperature was 25.6 ºC (± 0.3 ºC) and humidity was 78.7 (± 5%). The motor activity was recorded at 5 min bins by infrared movement sensors installed at the top of the cages. The motor activity profile was distinct at the two conditions: without the sleeping box protection against light, the activity frequency was higher at CT 11-12 (ANOVA; F(3.23) = 62.27; p < 0.01). Also, the duration of the active phase (α) was prolonged of about 1 h (t test, p < 0.05) and the animals showed a significant delay on the activity onset and offset (t test, p < 0.05) and at the acrophase (confidence intervals of 5%) of CAR. In LL, the light continuous exposure prolonged the active phase and influenced the endogenous expression of the circadian activity rhythm period. From the result analysis, it is concluded that the light self-selection can modify several parameters of CAR in marmosets, allowing the study of the synchronization mechanism using the burrow model. Thus, without sleeping box there was a phase delay between the CAR and LD (entrainment) and an increase of activity near lights off (positive masking). Furthermore, in LL, the light continuous exposure modifies α and the endogenous expression of CAR. It is suggested that the light self-selection might be take into account at investigations that evaluate the biological rhythmicity in marmosets

A auto-estima da criança que sofre violência física pela família

This research investigates the self-esteem of children who suffered physical violence by family members. Seven children took part in the research: three boys and four girls, aged between six and twelve years old. The analysis were done from the constructed data obtained from: semi-structured interview, activities about human feelings, activities that included facial expressions, unfinished phrases, Pinocchio s story, a drawing of a family and a drawing of their own family. Data were analyzed from the Content Analysis. The Thematic Units were: violence, intrafamily violence, and self-esteem. The synthesis of the categories studied evidenced that the physical violence and the psychological violence present in the lives of children affect the positive development of their self-concept and, consequently, of their self-esteem. Among the results, we emphasize some negative feelings that are present in children s lives such as fear, a sense of guilt, and sadness, arising out of the situations of violence they have experienced

A constituição da identidade em crianças vítimas de abuso sexual

Subject s identity is constituted in the relation with the other, which is characterized by dialeticity, and is configured as an identification and/or recognize movement, and strangeness and/or distance. In social interactions, people with whom subject relates himself assign meanings to him and, from these, the subject will ressignify, producing sense about himself. In other words, is through these interactions that subjects organizes themselves, recognize what is yours, and acquire the sense about themselves. It can be highlighted, too, the social-historic context s importance in the self-constitution process, whereas, from this, the subject produces particular forms of perception about reality charged with cultural meaning. Thus, the self-conception, the manners of thinking, of being, of relates, of take position against experiences, coming from values internalization, roles and related, are permeated by the manner witch the others relates themselves with the subject. However, when the relation with the other happens to be in a violent way, like in children sexual abuse, there are implications in the subjects constitution, whereas violates his physical and psychological integrities, as well as the rights of dignity, respect and even healthy physical, psychological and sexual developments. Therefore, this work aims to investigate how the identity process is constituted in children victims of sexual abuse. As specific aims the research proposes: 1) to characterize the relations between child and abuser, before and after the abuse act; 2) to identify images that the subjects, abuse victims, have about themselves and; 3) to identify the features of subject s relation with their own body. Toward this aims, procedures involving drawings, painting, collage, photography, activities with cardboard, colored pens, glue and tissue snips. The research took place at the Social Assistance Specialized Reference Center, where there is the treatment of children who suffered of rights violation, which includes sexual abuse. The research subjects were 3 girl children, between 6 and 10 years old, victims of sexual abuse. The corpus analyses was done through Thematic Content Analysis, structured in three meaning nucleus: 1) self-reference without the explicit attendance of other s discourse; 2) self-reference with the explicit attendance of other s discourse; 3) The other abuser. The analysis indicates that children, research subjects, have deteriorated images about themselves, about their bodies, which is consistent with the studies in the children and adolescents sexual violence field. In the other hand, were identified, too, self-references with positive values in the cases with mention about their way-of-being, which can be read as important to subject s development. About the other s discourse towards the subjects, were identified positive observations and found that these can contribute to subject s self-image reorganization. The contribution of negative comments, on the other hand, was showed in a more clear and incisive form in subject s constitution. There is, yet, an overvaluation of the other s discourse, so the meanings attributed toward them by the other are internalized, overshadowing the self-appreciation. To conclude, it can be highlighted that the need of psychological accompaniment of the children victims of sexual abuse, based on the possibility of this trauma experience elaboration, trying to overcome, as well as can be expected that this research s results contributes to the practices of professionals who work with subjects who have their rights violated

De vilarejo a cidade: identidade de lugar de moradores nativos de Tibau do Sul-RN

This study aimed to analyze some indicators of the restructuring process of place identity of natives resident in Tibau do Sul, a coastal town in the state of Rio Grande do Norte state, in relation to changes occurring in this locale in the last few decades. The concept of place identity a complex psychological structure in constant process of restructuring stresses the focus of this analysis on the aspects referring to the relationships of people with their physical and social environment throughout the transition process from the former village of fishermen and peasant farmers to the current growing town. Interviews with insider informants on local history were carried out as a preliminary step to getting in touch with the native participants. In total, 29 native local residents were interviewed, according to a wide range of personal and professional roles, focusing on their cognitions in regard to their past and present relationships with this context, as well as those related to expectancy for the future. The analysis focused both on the elements of distinctiveness, continuity, self-esteem and self-efficacy, and on how each of them have been valued (positive or negative). The participants evaluations of themselves and of the locale, as well as their distinctions in relation to others (people and places) were, in general, very positive. Many elements of group and place continuity, and the possibility of the satisfaction of their needs were highlighted positively, especially comparing to similar situations in the past. The development of the town, related to tourism as well as to other former economic activities, seemed to contribute to the restructuring process of place identity in a way of achieving desirable states for its structure. The broadening of the analysis to consider a wider spatial and temporal context, however, shows that such positive evaluation can be said to hinder some coping strategies of local residents faced with unsustainable economic activities, oftentimes handled to favor a minority of the population

Análises físico-químicas de polpas de frutas e avaliação dos seus padrões de identidade e qualidade

The pulps are products that add economic value enjoy the fruits of the surplus productions of the same. Have good market acceptance because of its practicality and diversity of flavors available year round. In order to assess the quality of the fruit pulp through the physical and chemical parameters and the characteristics of manufacturing industry, we analyzed 36 samples of frozen fruit pulp of three brands marketed in RIO Grande do Norte, 14 brand A, 12 of 10 brand B and brand C, which corresponded to 14 different flavors, of which 10 have identity Standards and Quality (ISQ S) established by the Ministério da Agricultura, Pecuária e Abastecimento (MAPA), totaling 27 samples with ISQ s. We conducted the following physicalchemical analyzes on samples of fruit pulp: Total solids, total soluble solids, pH, titratable acidity, total sugars and the determination of ascorbic acid. The percentage of failure for each parameter evaluated was 37, 04% in total soluble solids, 22,22% for total solids and titratable acidity, 7,40% in relation to pH. The total sugars were within the requirements demanded by the MAPA and ascorbic acid content, determined only in the pulp of acerola and cashew, presented a non compliance in the pulp of brand B. The percentage of failures of the pulps with ISQ S was 59% with brand A, B and C accounted for 3,70%, 33,33% and 22,22% respectively. The pulps which have no established atandards such as pineapple pulp, showed similar values between brands and literature data unlike the pulp of plum, jackfruit and tamarind which diverged greatly in parameters such as total solids and total soluble solids. The study demonstrates the need for greater quality control by the producers with respect to raw materials, processing, packing, stored and the importance of ISQ S to establish the flavors have not yet covered by existing legislation, but already highly commercialized

Uma abordagem dirigida por modelos para desenvolvimento de middlewares auto-adaptativos para transmissão de fluxo de dados baseado em restrições de QoS

The use of middleware technology in various types of systems, in order to abstract low-level details related to the distribution of application logic, is increasingly common. Among several systems that can be benefited from using these components, we highlight the distributed systems, where it is necessary to allow communications between software components located on different physical machines. An important issue related to the communication between distributed components is the provision of mechanisms for managing the quality of service. This work presents a metamodel for modeling middlewares based on components in order to provide to an application the abstraction of a communication between components involved in a data stream, regardless their location. Another feature of the metamodel is the possibility of self-adaptation related to the communication mechanism, either by updating the values of its configuration parameters, or by its replacement by another mechanism, in case of the restrictions of quality of service specified are not being guaranteed. In this respect, it is planned the monitoring of the communication state (application of techniques like feedback control loop), analyzing performance metrics related. The paradigm of Model Driven Development was used to generate the implementation of a middleware that will serve as proof of concept of the metamodel, and the configuration and reconfiguration policies related to the dynamic adaptation processes. In this sense was defined the metamodel associated to the process of a communication configuration. The MDD application also corresponds to the definition of the following transformations: the architectural model of the middleware in Java code, and the configuration model to XML

Detecção e diagnóstico de falhas não-supervisionados baseados em estimativa de densidade recursiva e classificador fuzzy auto-evolutivo

In this work, we propose a two-stage algorithm for real-time fault detection and identification of industrial plants. Our proposal is based on the analysis of selected features using recursive density estimation and a new evolving classifier algorithm. More specifically, the proposed approach for the detection stage is based on the concept of density in the data space, which is not the same as probability density function, but is a very useful measure for abnormality/outliers detection. This density can be expressed by a Cauchy function and can be calculated recursively, which makes it memory and computational power efficient and, therefore, suitable for on-line applications. The identification/diagnosis stage is based on a self-developing (evolving) fuzzy rule-based classifier system proposed in this work, called AutoClass. An important property of AutoClass is that it can start learning from scratch". Not only do the fuzzy rules not need to be prespecified, but neither do the number of classes for AutoClass (the number may grow, with new class labels being added by the on-line learning process), in a fully unsupervised manner. In the event that an initial rule base exists, AutoClass can evolve/develop it further based on the newly arrived faulty state data. In order to validate our proposal, we present experimental results from a level control didactic process, where control and error signals are used as features for the fault detection and identification systems, but the approach is generic and the number of features can be significant due to the computationally lean methodology, since covariance or more complex calculations, as well as storage of old data, are not required. The obtained results are significantly better than the traditional approaches used for comparison

Culinária do Seridó: um elemento da identidade territorial

This work aims to analyze the local cuisine as an element of territorial identity from Seridó Rio Grande do Norte State in the contemporaneousness - XXI century, where it takes place one motion, seemly contradictory, yet dialogical, in the way of eating locally is modified by food diversity and yet is lauded as an element of resistance, that is, of identification. Based on the perspective that groups go over time outlining on the territory their eating cultural characteristics, we have noticed that the spatiality from the local cuisine has happened during the territorial structuring process, being susceptible to the social, economical and technological changes, that hover over this space. On the unfolding days it was created a whole semiology around the cookery , incorporating to its territory of living, symbols, images, knowledge, tastes, feelings and smells that legitimate a way of being, better saying, of eating. But not all of the plates that congregate these aspects, only the oldest, the most emblematic. Within the diverse intercrossing of culture at Seridó region, they are the ones that maintain the vinculum from the group with its culture and with its territory, reminding what they are, or at least what they were, conferring them a legitimacy before those to whom they relate. The cookery from the Seridó region, this way is a cultural geo-symbol that turn this space significant and visible, for ordering the inside characteristics from the group before the new socio-cultural models present in the territory
