This study investigates the applicability of the Rorschach Method for evaluating the personality of people with Autism Spectrum Disorder (ASD).The relevance of this study is justified by the limited number of investigations published in the research literature concerning the use of psychological tests used for evaluating the personality of individuals with ASD. The Rorschach Method was chosen as an appropriate instrument considering it reveals the personality s basic structure, including characteristics of the affectivity, sensuality, inner life, mental resources, psychic energy and general characteristics and intellectual state of the individual. The general objective of this investigation consisted of verifying the applicability of the use the Rorschach Method in the evaluation of the characteristics of people's personality with autism spectrum disorder (ASD).The study also sought to identify perceptive factors of the personality structure of individuals with ASD, provide contributions of the understanding of this syndrome, seeking the establishment of possible therapeutic interventions starting from diagnostic by Rorschach Method. In addition, this investigation aims at verifying the adequacy of using the Rorschach Method as an instrument for evaluating the personality characteristics of individuals with ASD and its possible use in Brazil, starting from preliminary normative results. Participants consisted of 44 youngsters and adults, both genders with age range 14 - 39 years-old (average: 23.5 years-old) distributed in 2 groups. Group 1: composed with 22 youngsters and adults with clinical diagnosis of autism spectrum disorder (communication impairments, social interaction deficits, restricted and repetitive interests and activities); Group 2: composed with 22 youngsters and adults with typical behavior. The participants were paired to gender and age, individually. The Mann-Whitney and Wilcoxon tests were applied to evaluate statistical differences between the groups, considering demographic and social data. The results indicate the presence of restricted interest or difficulty in the expression of the social and affective interaction of people with ASD. However, the need of broader normative studies concerning the use of personality evaluation instruments for people with ASD is warranted. These investigations could help understand the psychic dynamism of this population, offering subsidies that can be added to the current techniques of diagnosis. The Rorschach Method is susceptible to application but it is necessary to respect the individual limitations of these people and to establish more criterions about the spectrum

Autism constitutes one of the most important pathologies of the pervasive developmental disorders (PDDs). It has early age-onset and is characterized by delay and deviance of social, communicative and cognitive development. Today, the presence of genetic factors in its etiology is well known, with familial recurrence of autism and other psychiatric conditions. Autism does not have usual Mendelian inheritence and presents genetic heterogeneity. Strong association has been found between autism and the fragile X syndrome (FMR-1 gene) and with tuberous sclerosis (Bourneville's syndrome). However, many different chromosomal abnormalities were recently described in autistic patients, mainly of chromosome 7 and 15. There are some genes on 15q11-q13 whose products have expression in the central nervous system, mainly synapses, which are subunits of neurotransmitters or ion channels (UBE3A, GABRA5, GABRB3, GABRG3, CHRNA7 e ITO). Some regions of chromosome 7 also have important developmental genes, as EN-2 and HOXA, which act on central nervous system formation. There seems then to exist genes associated with autism etiology on chromosomes 7,15 and X. The detailed study of these chromosomes can produce knowledgment about the biological mechanisms involved in this disturbance.

Esta dissertação apresenta uma avaliação dinâmica da conexão Tucuruí-Manaus-Macapá ao Sistema Interligado Nacional frente a pequenas e grandes perturbações. Todos os dados utilizados foram obtidos da base de dados do Operador Nacional do Sistema Elétrico. No entanto, os parâmetros dos estabilizadores dos sistemas de potência das usinas de Macapá não estão sintonizados para a interconexão e as usinas de Manaus não apresentam dispositivos suplementares amortecedores. Sendo assim, o objetivo deste trabalho é projetar estabilizadores de sistemas de potência para as usinas hidrelétricas de Coaraci Nunes e Balbina, e também para as usinas térmicas de Mauá e Aparecida, através de técnicas de respostas em frequência baseada no critério de Nyquist. A utilização dos estabilizadores tem como finalidade o amortecimento dos modos eletromecânicos que surgem quando os sistemas isolados do Amapá e do Amazonas passam a ser integrados ao sistema interligado nacional. Os projetos são avaliados em diversos cenários operativos através de simulações no domínio do tempo.
