Desempenho de escolares com dislexia e transtorno do déficit de atenção e hiperatividade nos processos de leitura

This study aimed to characterize and to compare the performance of students with an interdisciplinary diagnosis of dyslexia and attention deficit hyperactivity disorder (ADHD) in students with good academic performance on the reading processes. Sixty students from both genders, from 2nd to 4th grades of municipal public schools in Marília - SP participated in this study, they were distributed as follows: GI, 20 students with interdisciplinary diagnosis of dyslexia; GII, 20 students with ADHD and GIII, 20 students with good academic performance, paired according to gender, age and grade level with GI and GII. The students were submitted to the application of the assessment of reading processes (PROLEC) composed by four processes: letters identification, lexical, syntactical and semantic. The results highlighted that the students of GIII showed superior performance comparing with GI and GII. There was difference between GI and GII only in low frequency word reading and non words reading of the lexical process. The inferior performance from GI and GII in the PROLEC tests can be justified by the difficulty on the coding and decoding abilities. In ADHD students this difficulty was due to impaired interaction between the visual, linguistic, attention and auditory processing and in the dyslexic students was due to failure at the phonological mediation process, which depends on the knowledge of rules of grapheme - phoneme conversion to the acquisition of word reading. These changes affect the reading achievement and the comprehension of the read text.

Desempenho cognitivo-linguístico e leitura em escolares com transtorno do déficit de atençào e hiperatividade

OBJECTIVE: the aim of this study was to compare the cognitive-linguistic skills performance and reading of students with Attention Deficit and Hyperactivity Disorder and students without behavioral and/or learning disorders. METHOD: the study included 20 students from 5th to 8th grade of elementary school. The students were divided into: Group I (GI): composed by 10 students with an interdisciplinary diagnosis of Attention Deficit and Hyperactivity Disorder, and Group II (GII): composed by 10 students without complaints of behavioral and/or learning disorders. The tests of metalinguistic skills and reading (PROHMELE) were used as procedure, composed of syllabic and phonemic identification, syllabic and phonemic manipulation, repetition of nonwords and reading tests. RESULTS: the results showed statistically significant differences between GI and GII, demonstrating that students from GI presented superior performances when compared to the students from GII. CONCLUSION: according to the findings of this study we can conclude that the difficulties presented by students with Attention Deficit and Hyperactivity Disorder can be attributed to inattention, hyperactivity and disorganization, characteristic of this diagnosis, and not to a disorder of language of phonological basis.

Os principais fatores que contribuem para o aparecimento do Transtorno Desafiador Opositor

This paper presents a review of the literature on the opposition defiant disorder (ALL), highlighting the main factors that contribute to the emergence of the problem. Although there are relatively few studies available on the subject to date. The literature suggests that an integrated set of aspects of biological, psychological and social can influence the onset of the disorder. However, although more research is needed in order to characterize the weight or importance of different variables.

O ambiente educativo e o desenvolvimento do indivíduo portador do transtorno do déficit de atenção e hiperatividade (TDAH)

The pedagogical context can become a mediator between teaching and learning process. In a research conducted to obtain a Master’s degree, I could see how intentional organized environment refl ects in the knowledge appropriation and internalization historically produced. The objective of this study is to raise hypothesis about the favoring of the potentiating context of learning in the development of the individual with the Attention Defi cit Hyperactivity Disorder (ADHD) as well as on the organization of pedagogic environment to mediate the actions of teaching and reading learning. It is the concern to meet children with behavior considered inappropriate for the classroom environment and failure before situations that involve them. The hypothesis is that when the teaching and learning environment provides motivation to the student and awakens in him the desire to produce knowledge and take ownership of it, it is possible that it may have a potentiating development of learning. As theoretical support, I used texts from Luria (1987, 1994), Vygotsky (1994), Vigotskii, Luria and Leontiev (1998), Beaton (2005),Graeff and Vaz (2008), Pastura, Mattos and Araujo (2005). The bibliographic research was the methodology used for the study.

O transtorno de déficit de atenção/hiperatividade no âmbito educacional

The purpose of this research is to study and explain the characteristics of Learning Disorders, especially Attention Deficit Disorder / Hyperactivity Disorder (ADHD). This will be done a literature search focusing on books that address the topic. It is considered that these disorders are characterized as one of the most common problems in education, especially in the early years of elementary education, may affect in different ways the students' performance. Thus, many students may not be following the school curriculum as a result of these disorders

Uso do método de Monte Carlo para simulação e detecção do espectro de raios-X gerado com feixes de elétrons em alvo de Molibdênio, utilizando o Geant4

The huge demand for procedures involving ionizing radiation promotes the need for safe methods of experimentation considering the danger of their biological e ects with consequent risk to humans. Brazilian's legislation prohibits experiments involving this type of radiation in humans through Decree 453 of Ministry of Health with determines that such procedures comply with the principles of justi cation, optimization and dose limitation. In this line, concurrently with the advancement of available computer processing power, computing simulations have become relevant in those situations where experimental procedures are too cost or impractical. The Monte Carlo method, created along the Manhattan Project duringWorldWar II, is a powerful strategy to simulations in computational physics. In medical physics, this technique has been extensively used with applications in diagnostics and cancer treatment. The objective of this work is to simulate the production and detection of X-rays for the energy range of diagnostic radiology, for molybdenum target, using the Geant4 toolkit. X-ray tubes with this kind of target material are used in diagnostic radiology, speci cally in mammography, one of the most used techniques for screening of breast cancer in women. During the simulations, we used di erent models for bremsstrahlung available in physical models for low energy, in situations already covered by the literature in earlier versions of Geant4. Our results show that although the physical situations seems qualitatively adequate, quantitative comparisons to available analytical data shows aws in the code of Geant4 Low Energy source

Discuntindo as concepções de professores do segundo ano do ensino fundamental sobre transtorno de déficit de atenção e hiperatividade (TDAH)

Researches show high rates of school failure on the part of students who are unable to learn, referring to them as the idea of an incapable individual and intended not to achieve the goals proposed during the school year. Among the most varied problems posed by teachers and that are instilled in students in order to justify the poor performance of the same, we find Disorder Attention Deficit Hyperactivity Disorder (ADHD). Faced with this problem the objective was to investigate teachers‟ conception of the second year of primary education on ADHD, knowing well the mechanisms of identification, confirmation and referral of these cases, as well as the appropriate treatment and teaching practices suggested. To achieve the proposed objective a literature search was performed supplemented by an empirical study in which we used two instruments to collect data: interviews and observation. The study included empirical two teachers from a state school and two teachers from a private school, all of a midsize city in São Paulo. The interviews showed that teachers of second grade of elementary school consider ADHD a neurological problem in order to be addressed, however, chose not to speak about the treatment carried out by drugs. The observations revealed that the discourse of these teachers are away from their practices, it is worth noting that the differences in these two situations studied - state and private network - are so disparate and interfere in this important teaching practice

A coordenação motora de indivíduos com Transtorno do Desenvolvimento da Coordenação (TDC): o ritmo em foco

The aim of the present study was to examine tapping synchronization in children with and without Developmental Coordination Disorder (DCD). Participants were 27 children from which 13 diagnosed with motor difficulties composed the DCD group and 14 children with typical development (TD) the comparison group. The experimental task consisted of performing 25 continuous tapping on a surface of an electronic drum with the preferred hand. Participants were required to tap in synchrony with an auditory bip generated by customized software. Three interval values the tapping task were tested: 470 ms, 1000 ms, 1530 ms. The dependent variables were constant error (CE) and absolute error (AE) and standard deviation of absolute error (SD of AE). The ANOVA 2 x 3 x 3 (Group X Age x Interval) with repeated measures in the last factor for the CE indicated significant interaction among Group X Age X Interval. For the AE and SD of AE the ANOVAs yielded significant main effect of Interval and a significant interaction between Group X Interval. The results of the present study indicated that children with DCD were less accurate and more variable in the tapping synchronization than children with TD. Differences in performance between DCD and children with TD become larger as the interval of the auditory signal increases.

Avaliação de métodos de triagem e de detecção fenotípica de ß-lactamase de espectro ampliado (ESBL)

The catalytic function of extended-spectrum β-lactamases can result in high degrees of bacterial resistance to β-lactamic antimicrobials and in the emergence of ESBL among the members of Enterobacteriaceae family, especially Klebsiella pneumoniae and Escherichia coli. This occurs due to the dissemination and emergence of new variants of these enzymes caused by the high utilization of antibiotics like broad-spectrum cephalosporins. The ESBL are β-lactamases capable of conferring bacterial resistance to the penicillins, 1st, 2nd and 3rd generation cephalosporins, and aztreonam (but not cephamycins and carbapenems) through the hydrolysis of these antibiotics. In view of this phenomenon, the exact screening and detection of the producers of ESBL are essential for the appropriate selection of the antimicrobial therapy. The purposes of this study were to evaluate the best antimicrobial for the selection of ESBL producers and to determine the best method for the detection of such microorganisms. We evaluated 200 sequential bacterial samples including the species Klebsiella pneumoniae (56.5%), Escherichia coli (34%), Proteus mirabilis (8.5%) and Klebsiella oxytoca (1%), previously characterized as ESBL producers between February and September 2008 in the Laboratory of Microbiology, Botucatu Medical School - UNESP, Botucatu, São Paulo State, Brazil. To select the ESBL-producer bacteria, we used the disks recommended by CLSI 2008, aztreonam (ATM), cefpodoxime (CPD), ceftriaxone (CRO), cefotaxime (CTX) and ceftazidime (CAZ), besides cefepime (FEP). ESBL production was confirmed by three methods: double disk screening, ESBL Etest®, and Vitek® automated system. The disks employed in the double disk screening were: penicillin associated with β-lactamase inhibitor, amoxicillin-clavulanic acid, and two β-lactamic antibiotics, ceftazidime and cefotaxime...(Complete abstract click electronic access below)

Análise cinemática e cinética do salto vertical de crianças com transtorno do desenvolvimento da coordenação (TDC)

Due to motor difficulties, children with developmental coordination disorder (DCD) doesn't feel motivated to do physical activities, sometimes resulting in a decline of their physical fitness, but it isn't really known for sure the reasons that induct children with DCD to low performances in physical fitness tests, because a lot of tasks that are part of the battery of tests of physical performance are complex in the coordination and/or motor control point of view, like the vertical jump for example. Therefore, the objective of this study was to investigate the factors that induct children with DCD to low performances in physical fitness tests, especially in the vertical jump task. For that, cinematic (duration of the eccentrical phase, duration of the concentrical phase, shift of the mass center and velocity of the mass center), kinetic (potency peak and force peak) and vertical jump performance analysis in two conditions (with the use of arms and without it) were realized in a force platform. The results indicated that children with DCD show a lower performance compared to their peers with typical development (TD), due to a lower potency production

Caracterização da contribuição da albumina para a formação do espectro de ressonância magnética nuclear (RMN) do plasma sanguíneo

The plasma represents a average of the information referring biochemists to the physiology of the organism as a whole, therefore it indirectly or directly interacts with all tissues of the body. In such a way the plasma can be considered as a metabolic “soup”. Using the Nuclear Magnetic Resonance Spectroscopy sanguineous plasma spectra had been generated and using deconvolution techniques it was possible to know the contribution of the albumin for the formation of the spectra of the sanguineous plasma
