This work presents the processes and the results of a research concerning the affectivity in children suffering from the Down´s Syndrome (DS). The relevance of the study is justified due to the need of the development of researches, in the area of psychological evaluation of people who suffers from Down´s Syndrome (DS), that are backed by the use of appropriate instruments for such purpose. The thematic discussed focuses the characteristics of the affectivity of children suffering from Down´s Syndrome. Affectivity, conceptually, is considered a wide phenomenon, including several aspects such as emotions, passions, anxiety, anguish, sadness, happiness and even the pleasure sensations and pain. The general objective of the study consisted of investigating the manifestation of the affectivity in children and young with Down´s Syndrome and the parents´ and educators´ perception concerning the expression of the affectivity in the behavior and in the social activities. The specific objectives were: to identify the parents' perceptions about the several manifestations of indicative behaviors of affectivity; to verify in the social atmosphere, outside home, through the teachers' perception, the several forms and intensities of the expression of the affectivity; and, to make possible the use of the technique of Zulliger (Z-test) in people with Down´s Syndrome. 70 (seventy) children and young with Down´s Syndrome participated in the research, in the age group from 04 to 26 years old, which are attended by Institutions of Paraíba and of Rio Grande do Norte. The instruments used were two questionnaires, applied with the parents and teachers, and the projective technique, Z-test, applied, individually, with the children and young with Down´s Syndrome. For analysis of the data of the questionnaires, the program Trideux-Mots was used, with the intention of selecting the main outstanding words for the parents and teachers concerning the expression of the children's affectivity and young with Down´s Syndrome. For so much, it was organized a database that was processed by that program and, soon after, interpreted through the Factorial Analysis by Correspondence (AFC), looking for to clear the modalities of presented answers in an organized way, through a graph. The data of the Z-test were analyzed, taking in consideration the need to characterize the aspects of the affectivity and the elaboration of specific norms for this sample type, through normalized scores. In agreement with the data presented by Tri-deux-Mots, it was observed that in the affective behavior and in the relationship with the other, home and in the school, the children and young with Down´s Syndrome they express your affectivity through positive and negative characteristics, in the same way that any other child that doesn't have to syndrome. The Z-test made possible initial elements to work with that population, however it is necessary that grow other researches with the intention of investigating the reason of the answers they present not the specific categories that you/they are related to the affectivity, since it was well-known the diversity of affective characteristics presented by the researched group

The present study compared the expression of cytokeratins CK6, CK16 and CK19 and pan-cytokeratin (PAN) in oral mucosa cells between smokers and nonsmokers in order to determine the stage of cell differentiation and to consequently infer proliferative activity and expressions indicative of a potential for malignant differentiation. Thirty smokers and 30 non-smokers seen at the clinics of FOSJC-UNESP were screened. Smears were obtained from the left lateral border of the tongue with a cytobrush and slides were processed for immunohistochemistry using the antibodies reported Conventional microscopy was used for qualitative analysis. The results were analyzed statistically by the Z test, Fisher's exact test and comparison of two proportions (plus-4 confidence interval method). The expression of CK6 (p=0.002), CK16 (p=0.003), CK19 (p=0.0001) and PAN (p=0.008) was higher in oral mucosa smears from smokers compared to non- smokers. ln conclusion, increased epithelial proliferation is observed in the oral mucosa of smokers as demonstrated by the increased expression of CK6 and CKJ6, and these cells present alterations in epithelial maturation

Este trabalho tem por finalidade a construção de um instrumento psicológico de medida de comportamentos criativos, o Teste de Aptidão Criativa - TAC. A construção do TAC é justificada de um lado, por sua utilidade; sobretudo para o orientador profissional e psicólogo escolar e de outro; pela inexistência no Brasil; em particular no Nordeste, de instrumentos de medida similar. A formulação do problema e seu contexto são descritos logo no início do trabalho, bem como, a fundamentação teórica. Neste particular, enfatizou-se o enfoque psicológico da criatividade v em suas abordagens personológica e cognitiva. Atenção especial foi dada ao estudo do "modelo da estrutura do intelecto" de J. P. Guilford, suporte teórico do TAC. O teste de Aptidão Criativa é apresentado em todas as etapas de sua construção , desde a forma pré-piloto ç à piloto e à experimental, salientando-se seus respectivos subtestes figural e verbal. Ilustrações dos itens, bem como, das formas do teste são também apresentadas para melhor compreensão do texto. Em prosseguimento descreve- se uma pesquisa empírica realizada com o TAC, cujas hipóteses operacionais visam comprovar sua validade de constrito sua fidedignidade. A população foi constituída de alunos, de ambos os sexos, que cursaram em 1977 a 8a. série do 1º grau, de escolas públicas ou particulares; do município do Recife. O trabalho descreve detalhadamente a determinação da amostra, os instrumentos utilizados bem como os critérios de avaliação dos dados. O tratamento estatístico consistiu em medidas de tendência ceutra e de variabilidade; análise fatorial (técnica dos componentes principais-solução Varimax) para verificação da validade de construto. Os resultados obtidos, pela análise fatorial, demonstraram a presença de três fatores: um denominado C e interpretado como Convergente e dois, mensuráveis pelo TAC (conforme mostram as cargas fatoriais) que foram chamados de F (Fluência e Flexibilidade) e 0 Originalidade. O índice de homogeneidade calculado pelo “ de Cronbach" da característica originalidade entendida como essencial para a criatividade foi de 0,72. Tal resultado permite afirmar que na amostra testada o TAC , neste aspecto, apresenta fidedignidade significativa. Uma análise de regressão múltipla por passos foi levada a efeito, visando a identificação dos itens que mais contribuíram para explicação do escore total. Os resultados permitiram apontar uma melhor forma para o TAC figural constituída pelos itens I , II, V, VI , VII e VIII, os quais comporão a forma definitiva do TAC. Calculou-se também o estatístico Z do "Teste de urna Amostra de Kolmogorou para verificação da normalidade da distribuição das três características que o de medir: Fluência, Flexibilidade e Originalidade. Explicita-se ainda uma crítica à técnica de computação das respostas do TAC em face do índice de flexibilidade e propõe-se a realização de estudos, que permitam a formulação de novos procedimentos para um tratamento mais adequado das respostas aos estímulos do teste. Sugere-se também um estudo teórico sistemático de maior profundidade sobre os pontos de convergência entre as teorias psicológicas que tratam o tema para uma melhor compreensão da natureza e dinâmica do comportamento criativa. Propõe-se ainda a continuidade da pesquisa empírica que deu origem a este trabalho, tendo por objetivo imediato a padronização do TAC, de modo a poder ser ele instrumento útil ao psicólogo, na prática da psicologia aplicada.

PURPOSE: To compare the 2% ibopamine provocative test with the water drinking test as a provocative test for glaucoma. METHODS: Primary open-angle glaucoma patients and normal individuals were selected from CEROF-Universidade Federal de Goiânia UFG, and underwent the 2% ibopamine provocative test and the water drinking test in a randomized fashion, at least 1 week apart. Intraocular pressure (IOP) before and after both tests, Bland-Altman graph, sensitivity and specificity (as mesured by ROC curves) were obtained for both methods. RESULTS: Forty-seven eyes from 25 patients were included (27 eyes from 15 glaucoma patients and 20 eyes from 10 normal individuals), with a mean age of 54.2 ± 12.7 years. The mean MD of glaucoma patients was -2.8 ± 2.11 dB. There was no statistically difference in the baseline IOP (p=0.8) comparing glaucoma patients, but positive after the provocative tests (p=0.03), and in the IOP variation (4.4 ± 1.3 mmHg for ibopamine and 3.2 ± 2.2 mmHg for water drinking test, p=0.01). There was no difference in all studied parameters for normal individuals. The Bland-Altman graph showed high dispersion comparing both methods. The areas under the ROC curve were 0.987 for the ibopamine provocative test, and 0.807 for the water-drinking test. CONCLUSION: In this selected subgroup of glaucoma patients with early visual field defect, the ibopamine provocative test has shown better sensitivity/specificity than the water drinking test.

The first idea of this study is trat there may be a disturbance of the visuo-spatial function in cerebral palsy. This idea is based upon the theories of Luria and Piaget. The second idea of this study is that the computer can help the investigation of visuo-spatial function. With the intention of evaluating the spatial function in cerebral palsy, the literature related to these themes was revised. We justify the proposal of a new test to study visuo-spatial function. This test uses straight lines in four different orientations and the subject has to recognize and arrange them individually or sets of them. This was done through the use of pencil and papel, and computer. The results confirm that there is a spatial disturbance and that a better understanding of the subject's difficulties was made possible through the use of the computer and the Logo computer language.
