That study had the aim to validate an instrument to evaluate the knowledge about the Urinary Catheterization (UC) in males. Cross-sectional, descriptive, quantitative and methodological study, accomplished in Universidade Federal do Rio Grande do Norte (UFRN), Universidade do Estado do Rio Grande do Norte (UERN) and a private university from Rio Grande do Norte. Sample of 27 judges selected from the inclusion criteria: registered nurses, discipline of semiology and/or semiotics teachers, with at least 1 year of experience in the disciplines, to work at UFRN, UERN or in private university and agree to participate voluntarily with the signing of the Consent Form. Study developed in three stages: a) elaboration of twos instruments based on the scientific literature, resulting in a structured observation script type checklist consisting of 36 items and a knowledge questionnaire with 12 questions; b) submission of instruments to judges from June to September 2012, which should evaluate each item in "adequate," "adequate with changes" and "inappropriate", and make an overall evaluation of each instrument based on 10 requirements; c) and validation with a verification of the agreement level among the judges, through the application of Kappa Index (K) and Content Validity Index (CVI). It was used the consensus level higher than 0.60 (good) for Kappa Index and higher than 0.70 for CVI. The research project had favorable opinion from the Ethics in Research/HUOL (CAAE n. 0002.0.294.000-10). After being coded and tabulated, the data were analyzed using descriptive statistics. Of the 27 judges who evaluated the instrument, 77.8% are female, with a mean age of 36.6 (± 9.0) years, 63.0% worked in UFRN, 74.1% had master degree and 63.0% worked exclusively on teaching. The experience time mean in teaching was 7.9 (± 8.0) years and in the disciplines of semiology and/or semiotics in nursing was 5.5 (± 6.7) years. In judgment of the checklist and knowledge questionnaire, no step/question was considered inappropriate, since all achieved level of agreement within the established values. All the checklist steps obtained good to excellent K (between 0.60 and 1.00). Of the 36 items, 25 had excellent K (0.75 ≤ K <1.00) and excellent total K (K = 0.83). Regarding the IVC, all steps reached levels above 0.70 (between 0.74 and 1.00) and CVI total was 0.90. All questionnaire questions evaluated separately (K from 0.60 to 0.93 and CVI from 0.74 to 0.96) and generally (K from 0.79 to 1.00 and CVI from 0.89 to 1.00) had evaluation levels of content validity within the established values. The instruments were reformulated based on the agreement levels between judges and international guidelines, dissertations and scientific articles. Both instruments proved to be valid regarding to their content, allowing a clear and objective evaluation of knowledge and skills about UC, both nursing students as well as other students and health professionals, since the use of valid measures seeking the reduction of the risk of the results distorted

VoiceThread (VT) is a collaborative and asynchronous web 2.0 tool, which permits the creation of oral presentations with the help of images, documents, texts and voice, allowing groups of people to browse and contribute with comments using several options: voice (microphone or cell phone), text and audio-file or video (webcam) (BOTTENTUIT JUNIOR, LISBÔA E COUTINHO, 2009). The hybrid experience with VoiceThread allows learners to plan their speech before recording it, without the pressure often existent in the classroom. Furthermore, the presentations can be recorded several times, enabling students to listen to them, notice the gaps in their oral production (noticing) and edit innumerous times before publishing them online. In this perspective, oral production is seen as a process of L2 acquisition, not only as practice of already existent knowledge, because it can stimulate the learner to process the language syntactically (SWAIN, 1985; 1995). In this context, this study aims to verify if there is a relation between the oral production of the learners more specifically the grammatical accuracy and the global oral grade and their noticing capacity, how the systematic practice with VoiceThread, in a hybrid approach, can impact the learners global oral development, their oral production in terms of fluency (number of words per minute), accuracy (number of errors in hundred words), and complexity (number of dependent clauses per minute), and on their noticing capacity (SCHMIDT, 1990; 1995; 2001), that is, the learner s capacity of noticing the gaps existent in their oral production. In order to answer these research questions, 49 L2 learners of English were divided into an experimental group (25 students) and a control group (24 students). The experimental group was exposed to the hybrid approach with VT during two months and, through a pre- and post-test, we verified if this systematic practice would positively influence these participants oral production and noticing capacity. These results were compared to the pre- and post-test scores from the control group, which was not exposed to VT. Finally, learners impressions in relation to the use of this tool were also sought through a questionnaire applied after the post-test. The results indicate that there is a statistically significant correlation between the learners speech production (accuracy and global oral grade) and their noticing capacity. Besides, it was verified a positive impact of VoiceThread on the learners speech production variables and on their noticing capacity. They also reveal a positive reaction by the learners in relation to the hybrid experience with this web tool

The principal zeitgeber for most of species is the light-dark photocycle (LD), though other environment factors as food availability, temperature and social cues may act. Daily adjustment of the circadian pacemaker may result from integration of environmental photic and non-photic cues with homeostatic cues. Characterization of non-photic effects on circadian timing system in diurnal mammals is scarce in relation to nocturnal, especially for ecologically significant cues. Thus, we analyzed the effect of conspecific vocalizations and darkness on circadian activity rhythm (CAR) in the diurnal primate Callithirx jacchus. With this objective 7 male adults were isolated in a room with controlled illumination, temperature (26,8 ± 0,2°C) and humidity (81,6 ± 3,6%), and partial acoustic isolation. Initially they were under LD 12:12 (~300:2 lux), and subsequently under constant illumination (~2 lux). Two pulses of conspecific vocalizations were applied in total darkness, separated by 22 days, at 7:30 h (external time) during 1 h. They induced phase delays at circadian times (CTs) 1 and 10 and predominantly phase advances at CTs 9 and 15. After that, two dark pulses were applied, separated by 14 days, during 1 h at 7:30 h (external time). These pulses induced phase delays at CTs 2, 3 and 18, predominantly phase advances at CTs 8, 10 and 19, and no change at CT 14. However, marmosets CAR showed oscillations in endogenous period and active phase duration influenced by vocalizations from animals outside the experimental room, which interfered on the phase responses to pulses. Furthermore, social masking and relative coordination with colony were observed. Therefore, phase responses obtained in this work cannot be attributed only to pulses. Afterwards, pulses of conspecific vocalizations were applied in total darkness at 19:00 h (external time), during 1 h for 5 consecutive days, and after 21 days, for 30 consecutive days, on attempt to synchronize the CAR. No animal was synchronized by these daily pulses, although oscillations in endogenous period were observed for all. This result may be due to habituation. Other possibility is the absence of social significance of the vocalizations for the animals due to random reproduction, since each vocalization has a function that could be lost by a mixture of sounds. In conclusion, conspecific vocalizations induce social masking and relative coordination in marmosets CAR, acting as weak zeitgeber

Most of ontogenetic studies on circadian timing system have been developed on infants, adults and elderly. The puberty has not been a stage of life few studied, except for researches in human adolescents, that presents phase delay in sleep-wake cycle. However, few studies have focused on the basis of this circadian change due to methodological difficulties. Thus, an animal model to study the sleep-wake cycle at puberty is essential. In the common marmoset, a social primate, the circadian activity periodicity stabilizes around 4 months (juvenile stage) and the 8h period component has a seasonal variation. Puberty stage of this species begins near the 8th month of age in males and near the 7th month in females with 7 months of duration. With the aim to characterize the circadian motor activity rhythm during puberty in marmosets (Callithrix jacchus) the motor activity was continuous registered by actiwatches in 6 animals between 5-12 months. Since the social factor influence the behavior of this specie, behavioral observations were realized in 30 minutes windows twice/week to a general evaluation of the influence social interactions dynamic across experiment. Determination of puberty onset was done by fecal progesterone and estrogens in females, and androgens in males. From the analysis of the multiple regression test was selected a model that evaluate age and seasonal variables effect on the activity rhythm according to the higher explanation coefficient. The total activity was the only parameter influenced by age. Moreover, the activity onset was the parameter more explained by the model, and the sunrise was the factor that most influenced it. After the puberty onset, 2 dyads advanced the activity onset. The activity total decreased in 1 dyad and increased in 2 dyads. This increase may be related to the birth of infants in these families. The motor activity circadian component stabilized later in 1 dyad, coinciding with the puberty onset of these animals, while bimodality, caused by the 8 h component, was modulated by seasonality. The agonistic behavior was not evaluated due to reduced number of events. There were changes across ages in affiliative behavior of contact in 1 dyad, grooming done in 1 animal and grooming received in 2 animals. Although there is evidence of puberty effect on the activity motor rhythm, the photoperiodic fluctuations influenced the rhythm. Therefore is not possible to affirm if the puberty modulate the activity rhythm in marmosets

Food is essential for the survival of all animals. Its temporal availability is an important enviromental cue for the behavioral and physiological organization throughout the 24 hours of day in different species. Rats and mice, for example, show increased locomotion in the hours before food availability when it is presented in a recurrent manner, a behavior named foodanticipatory activity. Several lines of evidence indicate that this anticipation is mediated by a circadian oscillator. In this work, based on the hypothesis that pre- or post-ingestive humoral signals are involved in the entrainment process, we tested whether the daily intake of glucose is sufficient to induce anticipatory activity in rats. The rhythms of motor activity and central temperature were recorded in animals undergoing 10 days of temporal glucose (solution at 50%) or chow restriction in light-dark (LD) and constant darkness (DD). Animals under temporal glucose restriction increase motor activity and and central temperature in the hours preceding glucose availability and such aticipation is extremely similar to that observed in animals under temporal chow restriction. Glucose ingestion is, therefore, a sufficient temporal cue to induce anticipation in rats. It is possible that the increase in plasma glucose after food ingestion constitutes one of the signals involved in the behavioral entrainment process to food availability

Stroke is the leading cause of combined motor and cognitive disability worldwide. The rehabilitation of stroke patients is mostly directed towards motor recovery through the training of the affected member under supervision of a Physical Therapist. In the present study we introduce a new approach for both cognitive and motor therapy, which relies on motor imagery of the upper limbs and working memory training. This therapy should be utilized as an adjuvant to physical therapy. Ten individuals (5 men and 5 women) were selected for the pilot study, all of them in the acute phase of the first ischemic stroke episode. The control group had 5 individuals who were submitted to physical therapy only, whilst the other 5 patients in the experimental group also performed the cognitive and motor training with a video game specially built for this study. Two patients left the experimental group before the end. Total training lasted for 9 weeks, 2 times a week, for half an hour. Patients reported they enjoyed playing the game, even though it required a lot of mental effort, according to them. Plus, they considered it had a beneficial influence in their activities of daily living. No side effects were reported. Preliminary results suggest there is a difference between groups in cognitive and upper limb motor evaluation following the intervention. It is important to notice that our conclusions are limited due the small sample number. Overall, this work is supported by other studies in literature focused in rehabilitation with motor imagery and working memory and indicate a continuity of the research, increasing total training hours

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

TEMA: função motora fina em escolares com dislexia, distúrbio e dificuldades de aprendizagem. OBJETIVO: este estudo teve por objetivo caracterizar o desempenho da função motora fina, sensorial e perceptiva em escolares com dislexia, distúrbio e dificuldades de aprendizagem e correlacionar estes achados à escrita destes escolares. MÉTODO: participaram deste estudo 80 escolares da 2ª à 4ª série do ensino fundamental, na faixa etária de 7 a 12 anos de idade, de ambos os gêneros, distribuídos em: GI: formado por 20 escolares com dislexia, GII: formado por 20 escolares com distúrbio de aprendizagem, GIII: formado por 20 escolares com dificuldades de aprendizagem e GIV: formado por 20 escolares sem dificuldades de aprendizagem. Os escolares foram submetidos à avaliação da função motora fina, sensorial e perceptiva e análise da escrita por meio da escala de disgrafia. RESULTADOS: os resultados evidenciaram que a maioria dos grupos apresentou desempenho inferior nas provas de FMF7 (oposição de dedos), S8 (grafoestesia) e P1 (imitar posturas). Os GI e GII foram os grupos que apresentaram desempenho inferior na maioria das provas em relação aos GIII e GIV. Quanto à grafia, observou-se que no GII todos os escolares são disgráficos. CONCLUSÃO: a presença de alterações motora fina, sensorial e perceptiva é característica de escolares com distúrbio de aprendizagem e dislexia, entretanto esta característica pode ou não ser encontrada nos escolares com dificuldades de aprendizagem, sendo, portanto, esta alteração responsável pelo comportamento disgráfico dos escolares com transtornos de aprendizagem deste estudo.
