Seleção de features guiada por atenção visual em imagens com fóvea

Visual attention is a very important task in autonomous robotics, but, because of its complexity, the processing time required is significant. We propose an architecture for feature selection using foveated images that is guided by visual attention tasks and that reduces the processing time required to perform these tasks. Our system can be applied in bottom-up or top-down visual attention. The foveated model determines which scales are to be used on the feature extraction algorithm. The system is able to discard features that are not extremely necessary for the tasks, thus, reducing the processing time. If the fovea is correctly placed, then it is possible to reduce the processing time without compromising the quality of the tasks outputs. The distance of the fovea from the object is also analyzed. If the visual system loses the tracking in top-down attention, basic strategies of fovea placement can be applied. Experiments have shown that it is possible to reduce up to 60% the processing time with this approach. To validate the method, we tested it with the feature algorithm known as Speeded Up Robust Features (SURF), one of the most efficient approaches for feature extraction. With the proposed architecture, we can accomplish real time requirements of robotics vision, mainly to be applied in autonomous robotics

Transtorno de déficit de atenção/hiperatividade e psicologia histórico-cultural

O Transtorno de Déficit de Atenção e Hiperatividade tem sido evocado como justificativa corrente para o fracasso escolar de um número expressivo de crianças, atribuindo-se a elas a responsabilidade por não aprender e isentando de análise a escola e a sociedade nas quais estão inseridas. A situação se torna mais alarmante uma vez que a literatura a respeito aponta dificuldades no diagnóstico e na intervenção sobre esse tipo de transtorno, devidas à falta de clareza sobre o que é esse quadro clínico e em razão da não existência de estudos consistentes acerca das consequências futuras do uso de estimulantes nas crianças. Para discutir essas questões, a primeira parte do artigo apresenta a concepção hegemônica desse tipo de transtorno e sua compreensão do psiquismo infantil. A segunda parte aborda a maneira como a psicologia histórico-cultural analisa o desenvolvimento da atenção e o controle voluntário do comportamento humano, redimensionando a compreensão sobre o transtorno. Finalmente, são feitas algumas reflexões acerca do processo ensino-aprendizagem em crianças com desenvolvimento parcial das funções psicológicas superiores e do papel da psicologia e da pedagogia na compreensão do fenômeno para que sirvam de subsídio a medidas práticas em relação ao problema.

Ética e clínica na atenção psicossocial: contribuições da psicanálise de Freud e Lacan

O objetivo central é discutir a possibilidade de uma ética pertinente ao conjunto de ações atualmente realizadas sob o enfoque da Atenção Psicossocial no campo da Saúde Mental Coletiva. Utilizando o método do ensaio, partirei da análise de algumas proposições importantes sobre a ética na Saúde Mental, presentes na literatura recente, e da experiência de vários anos no campo da Atenção Psicossocial como trabalhador, como assessor clínico-institucional do Ministério da Saúde e como formador de psicoterapeutas. Duas vertentes de análise são consideradas: éticas disciplinares, chamadas éticas da psiquiatria, incluindo uma tentativa importante de complementá-las criticamente sob o enfoque da ética do cuidado, e éticas fundadas em concepções psicanalíticas do sujeito e seu sofrimento, que destacam as dimensões do sujeito como entre social e como entre subjetivo ou entre sentido. Com base nas diretrizes do Sistema Único de Saúde e na psicanálise do campo freudiano, procura-se fundamentar a ética da Clínica na Atenção Psicossocial como ética do cuidar-se - base necessária para a construção do protagonismo dos sujeitos do sofrimento na produção do sentido necessário à superação do sofrimento e demais impasses que motivaram a procura de ajuda, e para a possibilidade de seu reposicionamento no entre social e no entre sentido; componentes da saúde em sintonia com a subjetividade singularizada referenciada nos Ideais socioculturais e no devir desejante. Demonstra-se que essa ética exige dos trabalhadores do campo a superação dialética dos modos de produção de saúde e subjetividade em sintonia com o Modo Capitalista de Produção e seus derivados autoritários.

A atenção em Saúde Mental em municípios de pequeno e médio portes: ressonâncias da reforma psiquiátrica

A partir da análise da Política Nacional de Saúde Mental formulada nos últimos anos e das experiências desenvolvidas após 1987 no país, procura-se compreender como o Sistema Único de Saúde tem contribuído ao avanço da reforma psiquiátrica nos municípios; verificar como a assistência oferecida nesses municípios está viabilizando os princípios da reforma psiquiátrica e a melhora das condições de vida dos usuários, bem como pesquisar o papel dos trabalhadores e gestores na construção de novas práticas de cuidado em Saúde Mental. A análise das práticas discursivas aponta que os vários segmentos sociais envolvidos na Saúde Mental conhecem os princípios e propostas da reforma psiquiátrica. No entanto, as gestões municipais não assumem integralmente as propostas do Ministério da Saúde para a área, sob a alegação de falta de recursos financeiros para a contrapartida exigida. Os usuários e familiares têm aos poucos assumido as novas propostas de intervenção, mas os mecanismos de participação e organização popular ainda são incipientes. Por fim, deve-se destacar que, para uma efetiva consolidação das propostas atuais da reforma psiquiátrica, é necessário um maior compromisso dos gestores com a atenção em Saúde Mental, maior investimento nas equipes multiprofissionais, o estímulo à organização e à participação dos usuários e familiares e a integralidade dos dispositivos de saúde, de assistência social e de cultura existentes nas cidades.

O psiquiatra na atenção psicossocial: entre o luto e a liberdade

No Brasil, vemos surgir, a partir da década de setenta, diversas propostas inovadoras no campo da atenção à saúde mental. A partir de então, multiplicam-se no país ambulatórios de psicologia e psiquiatria, hospitais-dia, residências terapêuticas e diversos núcleos/centros de atenção psicossocial. Transformados em política pública, os centros de atenção psicossocial espalham-se pelo país, preconizando um atendimento ambulatorial, interdisciplinar e de orientação territorial. Geralmente formado sob os auspícios de um grande hospital, o psiquiatra que se propõe a trabalhar, a partir da ótica psicossocial, imerso em uma pequena cidade, vê-se exposto às diversas contradições e ilogicidades do discurso psiquiátrico clássico. Os variados saberes locais são uma ameaça ao saber psiquiátrico medicamente constituído. Respostas, antes fáceis no interior do hospital, têm variadas implicações no território e adquirem uma complexidade para a qual o psiquiatra não se encontra preparado. Assim, este trabalho tenta demonstrar a dissonância entre essas duas espécies de psiquiatria: a clássica (afinada com a biologia, com a normatividade e com a instituição) e a psicossocial (que se volta para respostas localmente construídas e que se afina com o homem, em uma dimensão muito além do seu corpo).

Os Centros de Especialidades Odontológicas como suporte da atenção básica: uma avaliação na perspectiva da integralidade

The public dental services in Brazil were limited, practically, to the basic care, so that the specialized services acted, up to 2002, no more than 3,5% of the total of clinical procedures. That lower offer reveals the difficulty of continuity of the attention, that is, the comprehensiveness in the assistance, particulary, the reference and counter-reference system. Brasil Sorridente search to supply those needs when proposing Speciality Dental's Centers(CEOs Centros de Especialidades Odontológicas, Brazil) to compose the services of average complexity. In 2005, Ministry of Health enabled the three CEOs of Natal, located in the North II, East and West Sanitary Districts. This investigation evaluated the implantation of these CEOs, as support of the family health care teams, in the perspective of organization of the services in assistencial nets in Natal/RN. It was a study of evaluation, with qualitative approach and some quantitative data as contribution. Dentists, users and managers were interviewed to identify and to understand their perceptions, relationships and experiences in the daily of the services. The conceptual base that orientated the investigation was the principle of comprehensiveness, in its operational sense of the hierarchization in health attention levels. The collection of data was done with documental research, direct observation and semi-structured interview. The analysis was accomplished by triangulation of the extracted content from the used techniques and sources of interviewed groups depositions, looking for theoretical-conceptual support in specific bibliography. The results pointed aspects that go away from the comprehensiveness like: low resolution of problems in the basic net; little valorization of the space in the health units; traditional models of access to health services, insufficient offer for some specialties, compromising the reference and counter-reference system; practices centered in procedures in the CEO; bureaucratic directions from basic care to the specialized service; disintegrated and disjointed system among levels of attention; disrespect to the municipal protocol. On the other hand, there is an approach of compreensiveness in situations like: increase of the access and covering in the Family Health Strategy (ESF Estratégia Saúde da Família, Brazil); larger approach between professional and user; tendency to the quantitative and qualitative growth of specialized actions; punctual initiatives of relationships among levels; existence of protocol to guide professionals

Perspectivados cirurgiões-dentistas sobre a inserção da fisioterapia na atenção básica de saúde

This work aims at investigating the surgeons-dentists acceptability in the field of public health in the city of Natal, State of Rio Grande do Norte, about the possibility of medicinal plants insertion in basic attencion of health. Moreover, it searchs to know if during their professinal formation it had some theoretician-pratical basement on this subject, as well as investigating their confidence on the medicinal plants. The basic motivation for developing this study is the possibility of contributing to the insertion of a tradicional health pratical at public assistance scope, endorsed by popular use, but now scientifically proven. For in a such way, the medicinal plants use is emphasized as a way to be followed to increase basic pharmaceutical assistance, improving the acess to the medicine and diminish expenses. Following this logic, family health program constitutes the way through which this pratical will be available to the users of health services. The research was done over thirty surgeonsdentists, all ofthem pertaining to public service ofNatal, state ofRio Grande do Norte. It was used, as research instrument, semi-estructured interview associated with methodological analysis user s speeches. On this form, this work is inserted in a trend observed nowadays not only in Brazil, where the use of the medicinal plants has been stimulated and defended to be inserted at programs ofprimary attenction of health

Centros de especialidades odontológicas: avaliação da atenção de média complexidade na rede pública da Grande Natal

The Specialized Dental Care Centers (CEO) were developed to provide specialized dental care to the population, given the accumulated needs of health since the past. They must operate as units of reference for the Oral Health Team of the Primary Care, complementing the dental procedures performed at this level of attention. This study aims to assess the performance of CEOs of the Grande Natal Health Region as a strategy of Secondary Care consolidation in oral health through users, dentists and managers. For this to try to identify factors about access, hosting and satisfaction with the service, the actions developed in these centers, integration between the CEOs and the Basic Health Units (UBS), considering the reference and counter reference. Data were collected through semi-structured interview, conducted in four CEOs, among 253 users, 31 dentists and 4 managers. It was submitted to descriptive statistical analysis and to content analysis by software ALCESTE 4.5. The results revealed that the specialties of prosthesis, endodontics and surgery were the most sought by 38.2%, 23.7% and 21.7% of respondents, respectively. It was noticed that among users aged 18 to 30 years-old the greatest demand is for the specialty of endodontics (44.4%) and over 50 years for prosthesis (76.4%). There is a weakness in the reference and counter reference between UBS and CEO, because part of users goes directly to the centers without going before to the Primary Care and the majority does not want to return to the dentist of Health Unit. Satisfaction with care was reported by 90.9% of users, because they resolved the problems needed and were welcomed by the team. But the delay in care was the main factor for not satisfaction. For most dentists, some users could solve their problems completely in Primary Care, which shows the existence of unnecessary referrals to the CEOs, however they consider the existence of limiting factors in UBS that compromise the service. Most dentists revealed that some users do not get to CEOs with the basic dental treatment done, and some of them do not counter reference users. It can be concluded that the studied CEOs are being resolutive for those who access them, offering necessary care for the population, and if they don t account with this service, will encounter obstacles to resolution of problems, ranging seek care service in particular, in another public sector, or even giving up treatment. However, it is perceived the need of professionals training to understand the importance of the reference and counter reference, to that they can better serve and guide users. It is also important that cities offer better conditions to UBS and CEOs, so they can work together, with complementary actions of oral health, seeking full care, aiming for better resolution to the users' health problems

Projetos políticos pedagógicos dos cursos de Odontologia do RN : formação profissional e a perspectiva da atenção à terceira idade

Brazil has been undergoing major demographic change.According to IBGE, the next 20 years the country's elderly population may reach over 30 million people. This tariff provides specifics regarding the process of health / disease. It is essential that higher education institutions are committed to this demand in view of the integrated training of health needs of society. The aim of this study is to analyze the Pedagogical Political Projects (PPP) of courses in dentistry in Rio Grande do Norte (RN), according to the national curriculum guidelines (DCNS) and training from the perspective of health care for the elderly. This is an exploratory study with a qualitative approach: with records and interviews. The study subjects were an Assistant Professor in the development of PPPs for each institution. The scenario in this study were dental training institutions in the newborns. Initially, the analysis of the PPP was by using the Alceste 4.9 software. The interpretation of the contents of interviews with teachers was done through content analysis of Bardin (2010). The PPPs are based on the DCNS, meet the characteristics of regional and seek a generalist, but still strongly directed to technical and scientific aspects of professional practice. Efforts and institutional approaches, involving teachers and students of the courses are being mobilized for training with more articulated network of health services. However, the emphasis on content pertaining to the health care of the elderly, is still limited when compared to those targeted content inherent in children and adolescents in all three curricular structures. It is reasonable to conclude that the historical, political, scientific, cultural and social, present in society, influence the formation of the dental professional RN. The greater participation of society in the process of vocational training in dentistry is needed. This can be done from the involvement of universities with health councils, bodies representing the dental profession and other segments of civil society in order to induce changes that generate ideas and educational practices integrative and interdisciplinary, with emphasis on continuing education for teachers, servants, employees and students. Containing conduct this process inherent flexibility of curriculum, teaching-service integration and coordination abilities and professional skills that are essential to understanding the human being and its complexities

Avaliação da saúde bucal na atenção básica: a perspectiva do usuário

Nowadays, the basic attention in health works according to the Health Family Program (HFP), which is responsible for the organization of the health services with view to provide an appropriate attendance to the needs of the population. Its expansion is expressive in whole country and, the oral health, included in this process, has been seen as a possibility of change the health practices centered in the disease. In face of this perspective, the proposal of study is to discover possible changes in the health care model of oral health in a district, made possible through the perception, evaluation and degree of satisfaction of the user s health service. To reach such objectives, the district of Macaíba in the State of Rio Grande do Norte, was chosen for operational subjects, such as time of implantation of HFP and great covering of this program. The current research used interviews structured with objectives and subjectives questions and questionnaires of socioeconomic characterization addressed to two hundred and seventy (270) individuals (ninety users of an Urban PSF, ninety of a Rural PSF and ninety of an unit non PSF). The analysis of the data was accomplished through the software SPSS/99, that made possible a statistical and analytic appreciation. The HFP units and non HFP units has shown to sort the common odontology problems of the community, and this didn't establish a direct relationship with the general satisfaction. On the other hands, the programmed consultation is related with lager satisfaction of the users. The access form to the odontology treatment of the Units, the satisfaction with the attendance rendered by the dentist and the equip, enough dentists for the community and the social class of the user were decisive for the general satisfaction with the service of oral health. On the other hand, variables as age and education, resolution of the problem and physical conditions of the unit didn't influence the general satisfaction. In spite of the progresses in the implantation of the oral health in ESF, preventive activities, visits at home, access and social participation still reproduce the traditional model of attendance, showing a primary change process

O papel das relações sociais e da atenção social durante tarefas cooperativas em Callithrix jacchus

Several studies on nonhuman primates show that the relationships between individuals strongly influence the expression of cooperative behavior, both in natural environment and in captivity settings. Recent studies suggest that cooperative breeders present outstanding performance in tasks involving social cognition, such as cooperative tasks with experimental apparatuses. In experimental research on this subject it is crucial to differentiate between real cooperation (or communicative cooperation, mediated by social attention) and by-product cooperation that results from simultaneous actions of individuals. The present study assessed, in Callithrix jacchus, a cooperative breeder species, if social relationships and social attention between subjects are important factors during performance in cooperative tasks. During the experimental procedure the animals participated in three different cooperative tasks: cooperation task, prosocial task and control task. Diverging from the literature, matrix correlation tests revealed no significant relationship between grooming or proximity and the execution of the tasks, suggesting that other factors such as age or hierarchy may have an effect on the performance in cooperative tasks in this species. There was also no relationship between the execution of the cooperative tasks and social glances, suggesting that there was no social attention during the tasks. Moreover, there were lower rates of social glances in the cooperative tasks as opposed to the control tasks. However, the small number of pulls in prosocial tasks suggests that the animals distinguished between tasks that benefited only a partner and tasks that generated benefits to themselves, choosing the latter. We conclude that, for the tasks presented in this study, we could neither detect the role of social relationships on the cooperative tasks nor assert that there were true cooperation and prosocial behavior

Nervos: rede de discursos e práticas de cuidado na atenção básica no município de Natal/RN

The Primary Health Care and one of its main strategies, the Family Health Strategy (ESF), are framed as the gateway to the Public Health System (SUS). Thus, most of the incident and prevalent health problems in the population attended should be solved at this level of care, including psychological suffering, and the so-called complaint of nerves. Nerves and nervous denote a complexity that is not always well comprehended by health workers, in such a way that the care to this kind of problem is usually inadequate. In this line of thought, the general objective of this study is to analyze the network of discourses and the care to the psychological suffering, expressed as nerves, in SUS daily Primary Health Care. Besides and more specifically, it aims at identifying the principles and guidelines of the Primary Health Care in mental health; to investigate health workers positioning before psychological suffering and complaints of nerves, and also analyze different actions and practices of care carried out in different Health Units towards complaints like nerves. Institutional Ethnography was the theoreticalmethodological perspective adopted for the work. This approach seeks to understand and analyze the institutional relationships in a particular context considering sociostructural influences and power relations, as well as daily discourses and practices. Based on interviews with health professionals, informal conversations and observations in six Health Units with ESF teams from different sanitary districts in Natal/RN, it was possible to check that the index of complaint of nerves is high. The referral to psychologists and psychiatrists, as well as the prescription of psychotropic drugs appear as the most common intervention at this level of care. In general, the participants complain that they have poor specialized knowledge about the theme of mental health. They face the problem of bad work conditions and the lack of institutional support, which make actions of illnesses prevention and health promotion even more difficult. Besides, there are different ongoing practices such as meetings for hypertensive and aged people, walk, visit, round-table discussions and community therapy. However, not all of these actions are aimed at the care of psychological suffering. It is observed that the Matrix Support, which is a methodological strategy of supervision and follow up forcases of mental health, hasn t been totally implemented in the municipal system, although it is a tool that has been used by psychologists in some Health Units in the city. It was also verified that the health care practices to the problem of nerves strongly depend on the professional s commitment with the PSF guidelines and on mental health policies, in addition to continued support, when available, from other professional who works as matrix supporter

A dimensão sociocultural da reforma psiquiátrica: articulando redes para a consolidação da estratégia de atenção psicossocial

This thesis aims to discuss on articulations that have been produced on the socio-cultural field in the Psychiatric Reform process and its pertinence to the streghtening of Psychosocial Care Strategy (EAPS) in Fortaleza/CE. Such interest has been justified by the need to promote not only the production of these networks, but also interfaces to enable strategies of support and sociability from the perspective of deinstitutionalization of madness. We were inspired by the cartography perspective of Deleuze e Guattari, and determined as objectives: 1) to discuss the complexity of Psychiatric Reform process and analyze the EAPS as a model for the current Mental Health policy in the country; 2) to map socio-cultural strategies connected to the CAPS network in the city, investigating experiences that already exist or may be constituted as everyday social support networks; 3) from that mapping to start, define and discuss some aspects that converge to the accomplishment for this new mental health paradigm, drawing a cartography of the issues and movements in progress. The mapping was carried out in 2009 and consisted of semi-structured interviews with the coordinators of the 14 existent CAPS and with some people connected to the Coordination of Mental Health. Besides, during the whole development of the study, we have taken part in public events that brought us clues on the connection between mental health and culture. From the survey produced, we defined three vectors for discussion (Art, Labour and Partnership with Social Movements) which have been highlighted as effective possibilities of intervention in the socio-cultural field of Psychiatric Reform in Fortaleza and reveal important paths on the fulfillment process of a new pattern of care. For each of these axes, we chose a field of empirical research (Projeto Arte e Saúde, COOPCAPS e MSMCBJ) in which we could better understand their strengths and difficulties, starting from open interviews with some of their actors and the production of a diary of sensations in 2010. We have seen that they are articulated with the proposal of EAPS, being part of the concerns to the National Mental Health Policy and also the municipal administration. However, we have noticed to be necessary to promote those dimensions further, focusing on its complexity at the macro and micro policies, with the purpose of leading the Psychiatric Reform process

Atenção precoce do câncer de mama :um olhar sobre o cotidiano institucional de uma unidade de saúde de Natal

Breast cancer has been considered a grave global public health problem due to its increase in incidence, in women s mortality and in the amount of financial resources spent on the therapeutic interventions used in the treatment of this neoplasia. However, this scenario presents some variations. In developing countries, the incidence of breast cancer is increasing but, on the other hand, the mortality is declining among patients because of public health actions toward early diagnostic that also result in cure of patients and decreasing levels of physical and psychosocial stress. In Brazil, we face of both the increasing number of breast cancer incidence and number of mortalities. Almost always the reason for that is a delayed detection that will provide a late diagnostic. The early detection of breast cancer has been studied in several researches. Some of them are concerned with women s experiences. Despite that, there is a lack of researches on dynamic comprehension of early attention to breast cancer from the health professionals points of view. The present research was carried out at the Unidade Mista de Felipe Camarão (UMFC) and it was conducted with 11 professionals who work in the Family Health Program (PSF). The aim was to understand how early diagnostic and attention to breast cancer is being planned, discussed and accomplished by health professionals in their day-to-day actions. Semi-structure interviews were held individually with each professional, in a way that they could feel free to express their ideas about several issues. All the information from these interviews was analyzed and discussed using an Institutional Ethnographic approach. It was observed that the actions of health professionals working with early detection of breast cancer does not take place in a vacuum; they occur within institutional, relational and social ways. This interdependence influences their actions and points of view on the theme
