The sleep patterns of students entering the university, is accompanied by many factors that can lead to changes in sleep habits, such as academic demands, new social opportunities, reduced parental care and irregular teaching schedules. The irregular pattern of sleep-wake cycle is usually accompanied by several daytime consequences, for example, reduced levels of motivation, performance, concentration, alertness and mood as well as increased fatigue and sleepiness.Thus, there are numerous reasons to support the fact that these students may suffer damage in their academic performance. The aim of this study was to evaluate the sleep-wake cycle (SWC) and cognition in medical students with different schemes teaching schedules. One group started classes at 08am, while the other started at 07am. We analyzed the data from 88 volunteers, 39 from each group. However, only those who participated in both stages of the study (n = 78) underwent cognitive testing. For subjective evaluation of the SWC was used questionnaires to check the quality of sleep, chronotype, daytime sleepiness and sleep habits. For objective evaluation was used actigraphy. For cognitive assessment was used the test MoCA (Montreal Cognitive Assessment). The results indicate that the group has class earlier had a greater irregularity of the SWC and a worse performance in cognitive testing. There was a difference between the schedules the week and weekend in the subjective variables, bedtime, wake up and sleep duration in both groups. The objective variables, time in bed showed difference between the schedules the week and weekend to the group started class at 08am and the variables bedtime, get up time, actual sleep time, time in bed and wake bouts in the class at 07am. In the cognitive test, there were differences between the groups in overall score and in the areas of executive function and memory recall. Thus, it is suggested that the class starting time may cause irregularity of the SWC and the irregularity may cause mild cognitive impairment. Moreover, cognitive testing MoCA was sensitive to detect differences among students, although the difference between the schedules is small

O estado vibracional (EV) é descrito como uma sensação de vibração intensa por todo o corpo, em que o sujeito se mantém num estado de relaxamento psicofisiológico que pode ser gerado de forma espontânea ou autoinduzida. Pessoas que aplicam esta técnica relatam alterações do estado mental e emocional, tais como: relaxamento, disposição, limpidez de pensamento, equilíbrio emocional, melhoria do raciocínio, bemestar, entre outros. Estas são, entretanto observações subjetivas, sendo a mensuração deste fenômeno uma lacuna e um desafio para a ciência. O objetivo desta pesquisa é explorar sistematicamente o estado vibracional no âmbito da neurociência. Desta forma, medidas eletroencefalográficas (EEG) foram utilizadas para observar se a sensação subjetiva de EV é acompanhada por mudanças na atividade elétrica cerebral. Além disso, para avaliar se o EV provoca algum efeito positivo em funções cognitivas como atenção e memória, foi utilizado um teste de reconhecimento de palavras antes e depois da aplicação da técnica de EV. Foram também aplicados questionários de dados gerais socioeconômicos e de saúde, do perfil de estados de humor, de qualidade do sono, além de inventários psicológicos. O foco inicial do trabalho foi a análise estatística dos dados de EEG, ficando as outras análises para uma etapa posterior. Dois grupos de voluntários foram analisados, o primeiro formado por 14 sujeitos que praticam a técnica de EV há pelo menos 10 anos (Grupo Experiente - GEXP), e o segundo formado por 11 sujeitos que nunca haviam realizado a técnica (Grupo Controle - GCONT). O GCONT obteve instruções sobre a técnica de EV antes dos experimentos. Foram realizadas análises estatísticas dos registros eletroencefalográficos, para comparar os grupos, em quatro condições: Basal, Relaxamento, Não-EV (período em que o sujeito está engajado na tarefa, mas ainda não percebe o EV) e EV (período em que o sujeito percebe o EV). Uma vez que os sujeitos do GCONT relataram não ter conseguido atingir a condição de EV propriamente, a comparação entre grupos foi feita apenas nas três condições, Basal, Relaxamento e Não-EV. Para isso, foi usado o teste de Mann-Whitney U com um limiar estatístico de p<0,05. De forma geral, o GEXP apresentou maior potência na banda de frequência alfa 2 (9,5-11,0 Hz) em todas as condições. Durante o período Não-EV, o GEXP também apresentou uma maior potência na banda de frequência alfa 3 (11,5-13,0 Hz) na região temporal esquerda, e gama 1 (30,5-55,0 Hz) e gama 2 (65,0-80,0 Hz) em regiões central, parietal e temporal esquerda, mas menor potência na banda de frequência teta 1 (3,5 - 5,0 Hz), em regiões centro-parietais. Para a análise estatística intragrupo, entre as condições, utilizou-se o teste estatístico Wilcoxon pareado. Observaram-se diferenças significativas (p<0,005), principalmente em regiões centrais, em teta 1 (3,5-5,0 Hz), sendo maior no Relaxamento, quando comparado com as condições Basal e Não-EV, no GCONT, e com o Não-EV e EV, no GEXP. No GEXP, a potência de gama 1 (30,5-55,0 Hz) e gama 2 (65,0-80,0 Hz) foi difusamente maior durante o EV, se comparado às outras três condições. Para o GCONT, apenas a condição Basal apresentou maior potência de gama 1 (30,5-55,0 Hz) e gama 2 (65,0- 80,0 Hz), se comparado com o Relaxamento. O aumento de teta 1 no Relaxamento, principalmente no GCONT, pode estar associado a uma maior sonolência deste grupo durante esta condição. Já o aumento de alfa 2 durante o Não-EV e o EV, pode estar associado com processos de atenção e cognição (DOLPPERMAYR et al., 2002; FELL et al., 2010; KLIMESCH et al., 1999; RAY E COLE, 1985). Por outro lado, o aumento da potência de gama em sujeitos experientes na técnica de EV encontrado aqui e em trabalhos anteriores, em meditadores experientes (FELL et al., 2010; LEHMANN et al., 2001; LUTZ et al., 2004), poderia estar associado a alterações nos processos mentais e cognitivos destes praticantes, tais como atenção, memória operacional, aprendizagem e percepção consciente embora, análises adicionais devam ser realizadas para excluir a possibilidade de interferência de artefatos musculares nos dados de EEG. Estes resultados suscitam a hipótese de que no engajamento da tarefa do EV e durante o EV, os sujeitos do GEXP conseguem manter-se em um estado de alerta, porém com maior nível de relaxamento e concentração. Uma inspeção mais detalhada dos dados, além de outros experimentos com diferentes protocolos, um maior número de sujeitos e pesquisas longitudinais são necessários para que testar esta hipótese

The lack of studies aimed at the mental health of the rural population, the social, economic, familial and emotional impact that mental disorders produce and the vulnerability that women have in this context, lead us to believe in the need to investigate the mental health demands of female rural workers, in order to subsidize the development of more effective and culturally sensitive public health programs and policies that take into account the specificities of this population. The present study aims to investigate the prevalence of common mental disorders (CMD) and the possible factors associated with the emergence of such disorders among women living in a rural settlement in Rio Grande do Norte. This survey has a quantitative and qualitative character with an ethnographic approach. As methodological strategies, we made use of an adapted version of the socio-demographic and environmental questionnaire prepared by The Department of Geology/UFRN s Strategic Analysis Laboratory to evaluate the quality of life of the families from the rural settlement and the mental health screening test Self-Reporting Questionnaire (SRQ-20) to identify the prevalence of CMD in adult women from the community. Complementing the role of methodological tools, we use the participant observation and semi-structured interviews with women who presented positive hypothesis of CMD attempting to comprehend the crossings that build the subjective experience of being a woman in this context. The results point to the high prevalence of CMD (43.6%) and suggest the link between poverty, lack of social support, unequal gender relations and the occurrence of CMD. We also verified that the settled women do not access the health network to address issues relating to mental health and that the only recourse of care offered by primary health care is the prescription of anxiolytic medication. In this context, the religiosity and the work are the most important strategies for mental health support among women

The move to include students with special needs (NEE) in the schools presents a paradigm that raises continual discussion about how to implement this proposal. Considering that learning is built from the weaving of socially constructed knowledge and the field of knowledge concerning subjectivity, this research explores the difficulties that occur with the later in the process of inclusion in the schools. Admittedly, the promise implicit in the school does not guarantee that the student learn, but the envisioning of this learning, when the student s educator discredits him, is such that the person is then not taken on as an actual student, being excluded from the transmission of knowledge, even within the school. The project implemented at the Instituto Educacional Casa Escola IECE, for the last three years, shows us that the possibility and sustainability of this envisioning is intimately linked to the subjectivity of the educator, as well as how one relates to the institutional culture. We question then, how this perspective is formed in the educator this perspective capable of denying the offer of a place as student, allowing him to advance while learning. With this in mind, we explore the paradoxical elements present in the paradigm of inclusion, as well as analyzing theoretically, through the body of conceptual psychoanalysis, the process of subjective constitution. We intend to bring to light how this process coincides with the construction of the educator s perspective of exemption from teaching the special needs students. We question, through the formative functions of subjective structuring (The Mirror Stage and the Oedipus Complex), how to form a perspective capable of promoting inclusion of special needs students in educators. Finally, we show how it is possible to bring to light, with the concepts of the I ideal and the ideal I, the subjective difficulties in the practicing instructor

This master s dissertation deals with motivation and the meaning of work amongst bank employees. This is done considering a cognitive perception. Work is understood here under a social and subjective comprehension, once it deals with significance attribution. Motivation is the process that rules choice of the different possibilities of individual behavior, all of which according to the Expectation Theory. This study aims to analyze the implications of the productive restructure, since it is related to technological innovation, organizational changes and management, in motivation and work significance. Thus, the objective of the research is to verify motivational differences and the meaning of work amongst bank employees. This is done in two distinct moments of the productive restructure of bank employees in Natal-RN. The research is divided in two parts. In the first one, changes that occurred in banks between 1999 until 2005 were identified by the means of interviews with 7 bank managers. The analyzed perspective was training intensifying, quality emphasis of customer attendance, the use of automation/technology, staff stabilization, change in staff profile, work intensification, etc. In the second study the Inventory of Motivation and Work Meaning was applied. Thus, questions related to work focus, social demographic data, in 187 bank employees were dealt with. The collected data was compared to data from previous work. It was observed that productive restructure has a reflection in the meaning of work increasing self-expression, economical reward, and responsibility in work conditions. All of the item mention beforehand maintain the level of inhumanness and consummation and respond as being the characteristics of the real work environment. On the other hand, bank employees value less justice, self-expression and more the survival perspective, implying instrumental values to work. As for motivation, it is increased among bank employees. These employees have greater expectations that their work produce results since they believe in their interference in work results

Most cochlear implant (CI) users, who suffer from post lingual hearing loss, are able to perceive sounds and comprehend speech after the implant. The prediction of maximal benefit over time, with the use of CI, can be useful for counseling patients about their expectations in using the new device. The measurement of satisfaction should be of primary interest in medical intervention, as the results may be used for intervention feedback. The purpose of this study is to analyze auditory performance of CI over time, as well as to evaluate users‟ satisfaction. Therefore two types of study designs were employed: a) retrospective cohort study with the analysis of medical records from 59 subjects about auditory performance before and after surgery. Results were submitted to the Kaplan -Meier estimator of cumulative probability and compared to prognostic factors of auditory performance using the logrank test. b) A sectional study design was conducted to evaluate the satisfaction of 51 subjects. The instrument consists of two specific questionnaires: Satisfaction with Amplification in Daily Life SADL and International Outcome Inventory Cochlear Implant IOI- CI. Results show statistical significant differences (p<0,001) in auditory performance before and after CI. The majority obtained satisfactory results of CI use during the first six months. Logrank tests does not indicate significant correlation between the analyzed covariates and the time in which adequate speech perception occurs. SADL e IOI-CI questionnaires indicate that most of the CI users are satisfied with their devices. The SADL detected a 27, 5% insatisfaction amongst CI users in relation to services and costs involved with the CI. The results of the IOI show 4% of insatisfaction with the use of CI and the social environment. In conclusion CI is capable to rehabilitate social auditory function in a short period of time and CI users demonstrate satisfaction with auditory, social and psychological gain offered through CI device

Nos últimos trinta anos de desenvolvimento capitalista, ocorreram transformações significativas nas diversas instâncias do ser social, com destaque para o mundo do trabalho e da reprodução social. Desenvolve-se o toyotismo, ideologia orgânica da nova produção capitalista, 'momento predominante' da reestruturação produtiva do capital. Sob o toyotismo, tende a constituir-se, pelo menos como 'promessa frustrada' do capital, o que iremos denominar 'compressão psicocorporal'. Esta constitui-se como um elemento da nova disposição sócio-subjetiva instaurada pelo toyotismo que caracteriza uma nova experiência do corpo, tanto no processo de trabalho quanto no processo sócio-reprodutivo.

There is a need for multi-agent system designers in determining the quality of systems in the earliest phases of the development process. The architectures of the agents are also part of the design of these systems, and therefore also need to have their quality evaluated. Motivated by the important role that emotions play in our daily lives, embodied agents researchers have aimed to create agents capable of producing affective and natural interaction with users that produces a beneficial or desirable result. For this, several studies proposing architectures of agents with emotions arose without the accompaniment of appropriate methods for the assessment of these architectures. The objective of this study is to propose a methodology for evaluating architectures emotional agents, which evaluates the quality attributes of the design of architectures, in addition to evaluation of human-computer interaction, the effects on the subjective experience of users of applications that implement it. The methodology is based on a model of well-defined metrics. In assessing the quality of architectural design, the attributes assessed are: extensibility, modularity and complexity. In assessing the effects on users' subjective experience, which involves the implementation of the architecture in an application and we suggest to be the domain of computer games, the metrics are: enjoyment, felt support, warm, caring, trust, cooperation, intelligence, interestingness, naturalness of emotional reactions, believabiliy, reducing of frustration and likeability, and the average time and average attempts. We experimented with this approach and evaluate five architectures emotional agents: BDIE, DETT, Camurra-Coglio, EBDI, Emotional-BDI. Two of the architectures, BDIE and EBDI, were implemented in a version of the game Minesweeper and evaluated for human-computer interaction. In the results, DETT stood out with the best architectural design. Users who have played the version of the game with emotional agents performed better than those who played without agents. In assessing the subjective experience of users, the differences between the architectures were insignificant

The monitoring of Earth dam makes use of visual inspection and instrumentation to identify and characterize the deterioration that compromises the security of earth dams and associated structures. The visual inspection is subjective and can lead to misinterpretation or omission of important information and, some problems are detected too late. The instrumentation are efficient but certain technical or operational issues can cause restrictions. Thereby, visual inspections and instrumentation can lead to a lack of information. Geophysics offers consolidated, low-cost methods that are non-invasive, non-destructive and low cost. They have a strong potential and can be used assisting instrumentation. In the case that a visual inspection and strumentation does not provide all the necessary information, geophysical methods would provide more complete and relevant information. In order to test these theories, geophysical acquisitions were performed using Georadar (GPR), Electric resistivity, Seismic refraction, and Refraction Microtremor (ReMi) on the dike of the dam in Sant Llorenç de Montgai, located in the province of Lleida, 145 km from Barcelona, Catalonia. The results confirmed that the geophysical methods used each responded satisfactorily to the conditions of the earth dike, the anomalies present and the geological features found, such as alluvium and carbonate and evaporite rocks. It has also been confirmed that these methods, when used in an integrated manner, are able to reduce the ambiguities in individual interpretations. They facilitate improved imaging of the interior dikes and of major geological features, thus inspecting the massif and its foundation. Consequently, the results obtained in this study demonstrated that these geophysical methods are sufficiently effective for inspecting earth dams and they are an important tool in the instrumentation and visual inspection of the security of the dams

A avaliação nutricional é ferramenta indispensável para a monitoração e acompanhamento clínico do paciente com lesão renal aguda (LRA). A perda aguda da função renal interfere no metabolismo de todos os macronutrientes, propiciando situações pró-inflamatórias, pró-oxidativas e de hipercatabolismo. As principais alterações nutricionais no paciente com LRA são hipercatabolismo, hiperglicemia e hipertrigliceridemia, que, somadas às contribuições da doença de base, complicações e necessidade de terapia renal substitutiva, podem interferir na depleção nutricional do paciente. A desnutrição em pacientes com LRA está associada a maior incidência de complicações, maior tempo de internação e maior mortalidade. Entretanto, existem poucos estudos na literatura avaliando o estado nutricional de pacientes com LRA. Parâmetros antropométricos como índice de massa corporal, circunferência do braço e pregas cutâneas são de difícil interpretação, devido à alteração no estado de hidratação desses pacientes. Os parâmetros bioquímicos geralmente utilizados na rotina clínica também sofrem influência de fatores não nutricionais, como prejuízo da função hepática e estado inflamatório. Embora não existam dados prospectivos sobre o comportamento dos marcadores nutricionais, alguns autores conseguiram demonstrar associações de alguns parâmetros com desfecho clínico. A utilização de marcadores como albumina, colesterol, pré-albumina, IGF-1, aplicação da avaliação subjetiva global e cálculo do balanço nitrogenado parecem ser úteis como parâmetros de triagem para pior prognóstico e maior mortalidade em pacientes com LRA. em pacientes com LRA em terapia renal substitutiva, uma oferta calórica em torno de 25 a 30 kcal/kg e oferta mínima de 1,5 g/kg/dia de proteínas é recomendada a fim de minimizar o catabolismo proteico e prevenir complicações metabólicas.

Two-level factorial designs are widely used in industrial experimentation. However, many factors in such a design require a large number of runs to perform the experiment, and too many replications of the treatments may not be feasible, considering limitations of resources and of time, making it expensive. In these cases, unreplicated designs are used. But, with only one replicate, there is no internal estimate of experimental error to make judgments about the significance of the observed efects. One of the possible solutions for this problem is to use normal plots or half-normal plots of the efects. Many experimenters use the normal plot, while others prefer the half-normal plot and, often, for both cases, without justification. The controversy about the use of these two graphical techniques motivates this work, once there is no register of formal procedure or statistical test that indicates \which one is best". The choice between the two plots seems to be a subjective issue. The central objective of this master's thesis is, then, to perform an experimental comparative study of the normal plot and half-normal plot in the context of the analysis of the 2k unreplicated factorial experiments. This study involves the construction of simulated scenarios, in which the graphics performance to detect significant efects and to identify outliers is evaluated in order to verify the following questions: Can be a plot better than other? In which situations? What kind of information does a plot increase to the analysis of the experiment that might complement those provided by the other plot? What are the restrictions on the use of graphics? Herewith, this work intends to confront these two techniques; to examine them simultaneously in order to identify similarities, diferences or relationships that contribute to the construction of a theoretical reference to justify or to aid in the experimenter's decision about which of the two graphical techniques to use and the reason for this use. The simulation results show that the half-normal plot is better to assist in the judgement of the efects, while the normal plot is recommended to detect outliers in the data

INTRODUÇÃO: O diagnóstico histopatológico de algumas lesões melanocíticas pode ser muito difícil, mesmo para especialistas, mas há casos em que a dificuldade surge pela inadequada e subjetiva aplicação dos critérios diagnósticos. OBJETIVO: O objetivo deste estudo é desenvolver um método de aplicação sistemática desses critérios, atribuindo valores para os mais importantes. MATERIAL E MÉTODOS: Selecionaram-se os critérios mais relevantes para o diagnóstico de melanoma, atribuindo valores de 1 a 5 de acordo com sua importância. Foram escolhidos 101 casos de melanomas de tipo extensivo-superficial com menos de 2mm de espessura para análise comparativa com 33 lesões melanocíticas benignas (13 nevos de Spitz, seis de Reed, seis displásicos, três congênitos, três adquiridos, um combinado e um recorrente). RESULTADOS: A soma dos valores dados aos critérios (score) apresentou diferença significativa entre lesões malignas e benignas, mostrando que esse método pode ser útil ao patologista cirúrgico generalista em sua rotina diária. CONCLUSÃO: A aplicação objetiva e sistemática dos critérios histopatológicos pelo sistema de pontos (scoring system) pode ajudar o diagnóstico diferencial entre maligno e benigno em muitas lesões, porém não tendo o efeito desejado nas lesões melanocíticas de comportamento biológico indeterminado.
