Este artigo apresenta uma breve revisão de alguns dos mais recentes métodos bioinspirados baseados no comportamento de populações para o desenvolvimento de técnicas de solução de problemas. As metaheurísticas tratadas aqui correspondem às estratégias de otimização por colônia de formigas, otimização por enxame de partículas, algoritmo shuffled frog-leaping, coleta de alimentos por bactérias e colônia de abelhas. Os princípios biológicos que motivaram o desenvolvimento de cada uma dessas estratégias, assim como seus respectivos algoritmos computacionais, são introduzidos. Duas aplicações diferentes foram conduzidas para exemplificar o desempenho de tais algoritmos. A finalidade é enfatizar perspectivas de aplicação destas abordagens em diferentes problemas da área de engenharia.

No momento em que se discute a inclusão de alunos com necessidades educacionais especiais em escolas regulares, faz-se necessário desenvolver trabalhos de pesquisa que se dediquem a analisar as implicações da formação continuada de professores. Neste sentido, estabeleceu-se o objetivo de investigar aspectos relativos às necessidades de duas professoras itinerantes, participantes de um programa de formação. Tal programa, voltado para o acompanhamento de alunos com baixa visão, pretendeu oferecer a essas professoras, sem conhecimentos específicos em deficiência visual, elementos dessa formação, e analisar a natureza das implicações evidenciadas ao longo do processo, do qual foi possível depreender que o desenvolvimento das funções visuais constitui-se em valioso referencial teórico, bem como o fato de estar regularmente na escola, conversar com as professoras, discutir como proceder, avaliar retroativamente os exercícios e ajudar a planejar estratégias com base nas análises feitas foram as principais vantagens de atuar de forma colaborativa.

Discute-se a determinação social da saúde materno-infantil nas Américas, a partir de inúmeras publicações e recomendações oficiais. Observou-se que nem todos os estudos valorizam apropriadamente as variáveis sociais e que muitos deles as consideram no mesmo nível de importância das variáveis biológicas. Como conseqüência, a compreensão final dos achados fica prejudicada e as conclusões e recomendações extraídas ficam longe de tocar a raiz dos problemas. Diferentes variáveis sociais (como escolaridade materna ou assistência médica) encontram-se freqüentemente associadas com variáveis biológicas (como peso ao nascer ou estado nutricional). Esta associação, no entanto, pode não representar uma relação causai, mas tão somente a ocorrência simultânea de características pertencentes a uma única classe social. Reitera-se a necessidade de estudos que reconheçam as classes sociais e analisem os resultados sobre saúde materno-infantil em relação às mesmas. Estes estudos provavelmente evidenciarão a importância social da saúde materno-infantil e evitarão as habituais diretrizes e recomendações restritas ao plano puramente técnico.

The aim of this work was to revise the main concepts involved in the physical-chemistry of the sol-gel process. First, the preparation and its influence on the gel's structure are focalized; the sol-gel transition is revised under the thermodynamics of crytical phenomena point of view and by considering the kinetic models of aggregation. Second, the experimental methods usually used to characterize the sol-gel transition are discussed.

Persistent cough leads individuals to seek for medical assistance. Clinical investigation, however, may not reveal any alteration within the clinic's sphere of action. Often enough, some professionals treat the symptom as a disease, introducing several medicines, unsuccessfully. The author's experience, as an otolaryngologist, allows to state that many of these professionals ignore the upper aerodigestive tract as a cough-generator site. The present work discusses the alterations on the mentioned tract, which may provoke the cough reflex, reviewing, initially, the cough mechanism and the localization of the specific receptors. Cough is produce by stimulus at the receptor level or far from it. In upper and lower parts of the aerodigestive tract secretions may run to several directions. Secretion from the paranasal sinus is a frequent cause of cough. Acute sinusitis may occur insidiously bringing about the chronification of the inflammation with cough being the only great apparent symptom. Nasal and dental alterations favor sinusal infection. Signs and symptoms, even if minimum, may be detected through an accurate anamnesis. Nasal allergy, laryngitis, post nasal dripping and septal deviation may also produce cough. The ORL examination is, therefore, imperative, and no radiologic examination can substitute for it. An inadequate treatment, particularly of the sinusitis, may bring about a worsening and extension of the initial condition.

This exploratory descriptive study, of qualitative nature had the purpose to study how the nurses from a hospital school see the family as care participants. Six nurses from clinics of chronically ill patients were interviewed. The data analysis allowed to infer that the nurses had only little knowledge of the family's thematic during graduation, making the relationship with the accompanying families very difficult. Daily care during hospitalization period is marked by easy moments when members are willing to participate in the process, and by difficulties when they attempt to break institutional rules. It was suggested that new nurses have theoretical foundation to attend the family in several scenarios of care. It was considered the need of investments in professional training, and that the advance of humanization of services implies in exchange and integration of knowledge among patients, family members, health professionals, support staff and managers beyond the science field.

In addition to cognitive impairment, apathy is increasingly recognized as an important neuropsychiatric syndrome in Alzheimer's disease (AD). Aims: To identify the relationship between dementia severity and apathy levels, and to discuss the association of this condition with other psychopathological manifestations in AD patients. Methods: This study involved 15 AD patients (mean age: 77 years; schooling: 4.9 years), with mild, moderate and severe dementia, living in Rio Claro S P, Brazil. Procedures included evaluation of cognitive status by the Mini-Mental State Examination, Clinical Dementia Rating, and Global Deterioration Scale. Apathy syndrome was assessed by the Apathy Evaluation Scale and Neuropsychiatric Inventory (NPI-apathy domain). Other psychopathological manifestations such as depression were also considered. Results: Patients with more severe dementia presented higher levels of apathy, reinforcing the hypothesis that apathy severity aggravates as the disease progresses. Using the Spearman coefficient correlation an association was identified between the MMSE and Apathy Evaluation Scale (r=0.63; p=0.01), and also between the MMSE and NPI-apathy domain (r=0.81; p=0.01). Associations were also found between the Global Deterioration Scale and Apathy Evaluation Scale (r=0.58; p=0.02), and between the Global Deterioration Scale and NPI-apathy domain (r=0.81; p=0.01). Conclusions: Apathy is a distinct syndrome among patients with AD and increases with global deterioration.

At this time, diverse views on deafness are present in society. Such views, in general, arecharacterized by theoretical disputes between communicative possibilities - either oral or gestural - based onthe importance of having appropriated oneself of a language code for the development of language, which isessential in the constitution of subjectivity of human beings. Thus, this study aimed to identify the conceptionsof deaf people had about their condition. To collect the data we used semi-structured interviews, applied toten participants who were deaf adult users of the Brazilian Sign Language - Libras. The interviews were taped,transcribed and subjected to content analysis. The results indicate that the conceptions of deafness constitute amultifaceted view on this condition, infl uenced by social relations throughout each person's life trajectories. Theresearchers perceived that learning Libras enabled deaf persons to constitute their own assertiveness as someonewho is different, with different needs.

The search for a dialogical interpretation on the concept theory is the purpose of this paper. It uses the concept of dialogism, proposed by Bakhtin, which refers to the interaction occurring among the social actors in the process of (re)construction of language. Starting from the analysis of texts on concept theory authored by Dahlberg, Hjorland, Tennis and Tennis and Sutton, the convergent, divergent and complementary aspects related to the concepts advocated by the authors are discussed. The analysis revealed that, although these concepts have been built individually, they are reflections of distinct currents of thought and of the historical moments that have influenced each author's ideas. It can be argued, therefore, that the studied concepts were developed on dialogue with other authors and among themselves.
