OBJETIVO: investigar a nomeação seriada rápida em crianças de uma escola pública e uma privada, com e sem queixas de problemas escolares. MÉTODOS: participaram do estudo 137 crianças dos gêneros masculino e feminino, com idade entre 7 e 11 anos, da cidade de Belo Horizonte, matriculadas no ensino fundamental, entre o 2º e o 5º ano. Foi aplicado o Teste de Nomeação Automatizada Rápida (Rapid Automatized Naming - RAN) que avaliou o tempo gasto pelo participante para nomear uma série de estímulos visuais familiares: cores, letras, dígitos e objetos - o mais rápido possível. RESULTADOS: os resultados deste estudo evidenciaram que o desempenho de alunos de escola particular comparado ao de alunos de escola pública é superior e que há uma diferença estatisticamente significante entre sujeitos com queixas de problemas de aprendizagem comparado aos sem queixas. CCONCLUSÃO: o presente estudo sinaliza que a capacidade de nomeação seriada pode ser considerada como uma das habilidades fundamentais para o bom desempenho em leitura. Sendo assim, há necessidade de continuidade de pesquisas que estabeleçam a relação dessa habilidade da linguagem com outras habilidades de leitura e escrita para verificação do impacto direto da nomeação seriada rápida no processo de aprendizagem da leitura.

Introduction: The effective development of reading and writing skills requires the concerted action of several abilities, one of which is phonological processing. One of the main components of phonological processing is rapid automatized naming (RAN)—the ability to identify and recognize a given item by the activation and concomitant articulation of its name.Objective: To assess the RAN performance of schoolchildren with dyslexia and attention deficit hyperactivity disorder (ADHD) compared with their peers.Methods: In total, 70 schoolchildren aged between 8 and 11 years participated in the study. Of these, 16 children had a multiprofessional diagnosis of ADHD while 14 were diagnosed with dyslexia. Matched with these groups, 40 schoolchildren with no history of developmental impairments were also evaluated. The RAN test was administered to assess the length of time required to name a series of familiar visual stimuli. The statistical analysis was conducted using measures of descriptive statistics and the 2-sample t-test at the 5% significance level.Results: The performance of the group with dyslexia was inferior to that of the control group in all tasks and the ADHD group had inferior performance for color and letters-naming tasks. The schoolchildren with dyslexia and those with ADHD showed very similar response times. Age was an important variable to be analyzed separately. As they aged, children with typical language development had fast answers on colors and digits tasks while children with dyslexia or ADHD did not show improvement with age.Conclusions: The schoolchildren with dyslexia took longer to complete all tasks and ADHD took longer to complete digits and objects tasks in comparison to their peers with typical development. This ability tended to improve with age, which was not the case, however, with schoolchildren who had ADHD or dyslexia.

Well integrity is very important for well operation in oil and gas industry. Advanced technologies and analyses have been developed to ensure well integrity. One of the most important analysis to be done is the evaluation of the cement bond which measures the presence and bonding of cement between casing and the formation in a particular depth or interval. This evaluation is critical for hydraulic isolation to withstand subsequent completion and production operation. Usually, Cement bond evaluation is done from wireline logging, with a tool that transmits acoustic waves and compute the acoustic energy propagating through the casing, the cement and the formation. The amplitude and the attenuation of the returned wave can be correlated with Bond Index (BI), due to the difference in acoustic impedance between casing and cement. Over years, different wireline technologies have been developed and matured for cement bond evaluation. Nowadays, it can be found scenarios where wireline operation is not feasible, such as in highly deviated wells or when a quick turnaround is needed. Acoustic technology in Logging While Drilling (LWD) has been developed to measure the compressional and shear slowness of the formation. These devices are able to transmit acoustic wave at different frequencies and receive them after propagation through a medium, applicable in cased hole condition. This paper presents a case study where the LWD Acoustic technology was successfully used to evaluate the cement bond in a high deviated well in Brazil and the results show the capabilities of the technology to generate a qualitative cement bond data quality. These results were successfully validated using sonic and ultrasonic wireline technologies. This comparison, between LWD acoustic and wireline results, is shown in this paper, including details of the methodology applied to the test, parameters considered and the data processing.
