Efeito da floretina na hidratação de vesículas neutras de agregados anfifílicos de DMPC

The effect of phloretin in the structure and hydration of dimiristoyl phosphatidylcholine vesicles (DMPC) was investigated by electron paramagnetic resonance technique (EPR) at the bilayer core of membrane, using 14-PCSL spin label derivative of phosphatidylcoline. The spectra obtained by pure DMPC vesicles and with addition of phloretin were simulated using the Nonlinear Least-Square program, at the tempearature between 15 oC to 50 oC. Through these simulations it was possible to analyse the membrane hydration and bilayer order, to understand the interaction between DMPC aggregates and phloretin. The results show that the phloretin decreases the membrane hydration in both gel and fluid phases. This reduction of water molecules is accompanied by increasing of the bilayer order at this micro-region

O prosumidor e as Relações Públicas na era da convergência midiática

This study supports the role of Public Relations within Organizations, inserted in the context of the media convergence age, in which all the medias complement each other and can be used together to achieve a given goal. The approach is exposed after reflection on consumers’ specificity and identity, in addition to an approach about media convergence age characteristics, such as collective intelligence, participatory culture and affective economy. Throughout this paper, it is also discussed the concept of Transmedia Storytelling and how consumers and communicators stories have become especially important in the convergence age. In this context, consumers are understood as prosumers, since they infer and influence brands, organizations or products, by using words. We showed that, because of those prosumers narratives, an organization may became susceptible to their image destruction in a short period of time or get more acceptance and profitability. Thus, Public Relations presents itself as a communication professional that can use several corporate strategies in the relationship between organizations and their different target audience

A experiência de trabalhar em ambiente de radioterapia

O procedimento da radioterapia não traz em si a garantia de qualquer resultado favorável, é preciso, antes, apostar em um planejamento minucioso e implementação cuidadosa do tratamento necessário para potencializar os benefícios da radioterapia através de sua aplicação. Primeiramente é preciso aplicar uma dose de radiação para as células tumorais em quantidade suficiente para matar as células cancerigenas no menor tempo possivel, aumentanto a possibilidade de controle da doença maligna, matando as células malignas e elevando a probabilidade de controlar a doença maligna, enquanto ao mesmo tempo, limita a dose para os tecidos saudáveis que circunda a célula com o tumor maligno, para que a probabilidade de dano induzindo a esses tecidos seja reduzida ao mínimo. Dentro desta perspectiva, o estudo teve por objetivo apresentar as atividades realizadas na Clínica de Radioterapia de São Carlos, procurando ampliar o conhecimento sobre a radioterapia para melhorar o atendimento aos pacientes com diagnóstico de cancer de mama e de cancer de prostata. Foi possivel neste período acompanhar a rotina de trabalho dos físicos médicos, que permitiram participar ativamente das atividades de planejamento, posicionamento do paciente, cálculo de dose, procurando manter a qualidade no atendimento aos pacientes. O estágio como componente curricular desempenha um papel fundamental no processo de formação. Responsável pela introdução do aluno no campo profissional, realmente possibilita a análise contextual dessa realidade na perspectiva de uma ação interventiva. Como aprendizagem maior é possível dizer que o estágio mostrou que nos dias atuais, os novos profissionais, se quiserem conquistar seu lugar, precisam juntar inteligência, conhecimento e capacidade emocional e social para enfrentar e poder atuar rumo às mudanças requeridas, a qualificação humana precisa ir além...

Interação humano-tv digital (IHTVD) e interatividade

With the development of Digital TV, the equipments are becoming more and more modernized in order to popular- ize the information that soon might reach all Brazilian families. That way, we open a space for discussion about the many directions that the usability applied on ISDB-Tb interactivity (Brazilian System of Digital Television) can take. This paper approaches the questions connected to the concept of usability and also the subjects related to the life cycle of some technologies (existence time, obsolescence) Also talks with the definition of interactivityon Digital Television since it is responsible for the emergence of a new contingent of interacting people which goes from the computer and portable equipments users to the passive TV viewers. It’s possible to conclude that the Human-Digital TV Interaction (HDTVI) comprehends the synergy between three actants on Digital TV: the col- lective (or not) TV viewer; the interface and the issuer who can be represented by an Artificial Intelligence (AI) service.

Importância da abordagem precoce no tratamento odontológico de pacientes portadores de necessidades especiais.

Introduction: the patients with specials necessities ne ed a singular dentistry treatment because they have limitations due to theirs deficiency. The quality of oral health is related to the clinical situation of patient. The individuals with motor and understanding problems have poor oral health. Aim: this st udy aimed to review the literature about the importance of the early dentistry treatment of pacients with specials necessities. Methodology: the review of literature was made through t he Pubmed and Bireme. Studies about dental caries and periodontal dise a se of patient s with specials necessities had shown high index of caries and periodontal disease. Therefore it is important that there are capacity p rofessionals and multidisciplinary treatment. It is necessary to supply the dificulties of treatment like an xiety of parents, systemic problems and discrimination. Conclusion: the early treatment results in good coperation during the treatment, and the aquisition of cares for all life. The best way is a program of oral health with instructions about diet, oral hygiene, control of bacterials, motivation and interaction between patients and professionals.

Representações de gênero na prática de enfermagem na perspectiva de estudantes

This study’s main goal was to investigate the representations of nursing students about the work of a nurse in a gender perspective, during the training process. The research used a sample of 41 nursing students (1st and 9th semesters) being applied to such a questionnaire, analyzed in the face of the organizer model concept, and also the critics studies of gender. Was found the research data, one is able to notice that, students that start off their academic lives in the nursing course have less stereotyped representations regarding gender behavior and certain problematization concerning the sexual division of the profession. When it comes to training, from the moment in which these students begin to live with the nursing practices, that are impregnated with stereotypes, in different contexts, the vision that once was considered generalizing, becomes crystallized, delimiting the practices that exist in nursing. The data points out to the need of the training courses to embark a problematization on the gender relations in the context of the nursing practices, given the fact they seem to reinforce standards, neglecting an egalitarian democratic and professional action in the professional field.

Equívocos na leitura da teoria de Jean Piaget

Dans cet article, nous présentons l'analyse des erreurs commises par rapport à l'épistémologie génétique et la psychologie de Jean Piaget. Nous nous appuyons sur un essai publié dans un périodique brésilien concernant la constitution du sujet d’enfance et la théorie de Piaget. Nous avons comme but d’aider à reprendre la «vraie» théorie de Piaget et de donner un aperçu aux lecteurs à fin de ne pas reproduire de telles erreurs ou être confrontés à de différents sens donnés à la même théorie. En ce qui concerne l'analyse, les auteurs du rapport disent que l'homme est le résultat de différents stades de développement et de ses phases. Cependant, en cherchant à expliquer comment les structures logiques deviennent nécessaires, Piaget a affirmé de ne pas rien avoir inventé. Il a conclu que la constitution des structures opératoires est le résultat de l'interaction du sujet avec le milieu, à condition qu'il dispose de certaines conditions prealables et qu’il soit capable d' établir ses rapports De cette manière, s'il a identifié des moments de la psychogenèse cognitive, il l’a fait grace à la constatation de que les sujets, dans cette interaction avec le milieu, finissaient par construire des manières qualitativement différentes de comprendre et gérer la réalité. Ainsi, Piaget n'a pas cherché de mettre les individus dans des phases ou périodes, artificiellement. Une autre erreur est celui de considérer que Piaget soit adepte de la dicotomie normalité/ anormalité. Ses préoccupations sont de nature épistémologique, et s'il est parvenu à formuler une psychologie, cela avait comme but de donner une base scientifique à sa théorie de la connaissance. Encore une autre confusion a lieu quand on affirme que Piaget a identifié les enfants aux peuples primitifs. Il a seulement dit que la nécessité d’entrer en relation avec le milieu est égale pour l'homme primitif comme pour celui d'aujourd'hui; par conséquent, le fonctionnement est le seul élément biologique considéré par Piaget, vu que tous les êtres vivants cherchent à s’adapter à la réalité. D’après cet angle, on constate que, de la même manière que l’homme primitif a été un enfant - comme ceux d’aujourd'hui - il a cherché à interagir avec le milieu à fin d'assurer sa survie. Il arrive que ses demandes étaient élémentaires du point de vue logico-mathématique, contrairement à nos jours. Une autre erreur consiste à dire qu'il a soupçonné ou admis que les processus de pensée reconnaissaient une organisation logique. Il ne s’agit pas de soupçon ni d'admission, mais d´une nécéssité. Faute de cette fondation, tout le bâtiment piagétien s’effondrerait. Nous concluons que le concept de progrès et l'état de l'intelligence sous-entendent la critique des auteurs. Malgré cela, et même pas sans admettre les explications formulées par Piaget, c’est le fait de que les censeurs doivent faire face à une vérité: indépendamment de la culture ou du moment historique, les enfants agissent toujours de la même manière, en cherchant à donner un sens à la réalité. Nous pouvons donc être d’accord ou en désaccord avec l'explication de Piaget. Cependant, il y a quelque chose qui ne doit pas être ignorée: la contribution apportée par Piaget vers la compréhension de la logique du fonctionnement mental.

Valores priorizados por estudantes universitários de um curso de psicologia de uma universidade pública

Most research on the psychology of morality defines moral as the rules and values whose purpose is to regulate interpersonal relations. In this study, although I have considered such premise valid, I have also taken into account aspects related to the self. Thus, aiming at verifying whether university students are guided by values which are public, private and/or linked to glory, I have analyzed the values prioritized by them. Informants were 170 first-year psychology undergraduates in a public university located in western São Paulo state, male and female, with an average age of 20 years. To collect the data, I applied a questionnaire concerning factual factors (age, sex and religion) and the values cherished by the undergraduates. The results – analyzed according to the psychology of virtues – have shown that approximately 70% of the valid answers given by students pointed friendship (32%) and intelligence (35%) as the most prioritized values. Public values were hardly mentioned. Concerning the forms of glory, although the percentage for money and fame was not significant, when the informants justified the choice of friendship and intelligence, they conceived such values as a means to obtain money and fame. I have concluded that these individuals give little importance to the values related to duties (which are public) and to some form of individual harmony.

Um modelo cognitivo baseado na atenção para consciência em robôs inteligentes

Understanding consciousness is one of the most fascinating challenges of our time. From ancient civilizations to modern philosophers, questions have been asked on how one is conscious of his/her own existence and about the world that surrounds him/her. Although there is no precise definition for consciousness, there is an agreement that it is strongly related to human cognitive processes such as: thinking, reasoning, emotions, wishes. One of the key processes to the arising of the consciousness is the attention, a process capable of promoting a selection of a few stimuli from a huge amount of information that reaches us constantly. Machine consciousness is the field of the artificial intelligence that investigate the possibility of the production of conscious processes in artificial devices. This work presents a review about the theme of consciousness - in both natural and artificial aspects -, discussing this theme from the philosophical and computational perspectives, and investigates the feasibility of the adoption of an attentional schema as the base to the cognitive processing. A formal computational model is proposed for conscious agents that integrates: short and long term memories, reasoning, planning, emotion, decision making, learning, motivation and volition. Computer experiments in a mobile robotics domain under USARSim simulation environment, proposed by RoboCup, suggest that the agent can be able to use these elements to acquire experiences based on environment stimuli. The adoption of the cognitive architecture over the attentional model has potential to allow the emergence of behaviours usually associated to the consciousness in the simulated mobile robots. Further implementation under this model could potentially allow the agent to express sentience, selfawareness, self-consciousness, autonoetic consciousness, mineness and perspectivalness. By performing computation over an attentional space, the model also allows the ...
