    OBJECTIVE:To assess and compare the sensory processing abilities of children with Attention Deficit/Hyperactivity Disorder (ADHD) and children without disabilities, and to analyze the relationship between sensory processing difficulties and behavioural symptoms presented by children with ADHD.METHOD : Thirty-seven children with ADHD were compared with thirty-seven controls using a translated and adapted version of the Sensory Profile answered by the parents/caregivers. For the ADHD group, Sensory Profile scores were correlated to behavioural symptoms assessed using the Child Behaviour Check List (CBCL) and the Behavioural Teacher Rating Scale (EACI-P). The statistical analyses were conducted using the Mann Whitney test and Pearson correlation coefficients.RESULTS : Children with ADHD showed significant impairments compared to the control group in sensory processing and modulation, as well as in behavioural and emotional responses as observed in 11 out of 14 sections and 6 out of 9 factors. Differences in all Sensory Profile response patterns were also observed between the two groups of children. Sensory Profile scores showed a moderately negative correlation with CBCL and EACI-P scores in the ADHD group.CONCLUSION : These results indicate that children with ADHD may present sensory processing impairments, which may contribute to the inappropriate behavioural and learning responses displayed by children with ADHD. It also suggests the importance of understanding the sensory processing difficulties and its possible contribution to the ADHD symptomatology.Universidade Federal de São Paulo (UNIFESP) Departamento de EducaçãoUniversidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) (EPM) Departamento de PsicobiologiaUNIFESP, Depto. de EducaçãoUNIFESP, EPM, (EPM), Depto. de PsicobiologiaSciEL

The development of this work is justified by the importance of contributing to the growth of Grape and Wine tourism in the municipality in which it is inserted. The methods to make feasible are exploratory documentary research, to know the routes who already exist in Brazil, and application of questionnaires to the visitors. During the analysis of results, the profile of the current visitor and their main needs were obtained. From this information, the work is finished with an innovative solution, so the route can be integrated to the technology, through new tools to retain their actual client and to solve with agility the problems

    Laparoscopically assisted percutaneous inguinal ring closure for resolution of inguinal/scrotal hernias in rams: cadaveric study and three cases report

    Get PDF
    The aim of this study is to evaluate a laparoscopically assisted percutaneous suture (LAPS) procedure to treat inguinal hernia (IH) while preserving testicles in rams. An ex vivo experiment with six ram cadavers and a report of three clinical cases are discussed. In cadavers, both internal inguinal rings (IIR) were partially closed by LAPS. Two LAPS methods were tested: (1) using a laparoscopic portal closure device and (2) using a suture loop inserted through needles in each IIR. After each procedure, the closure was laparoscopically evaluated and the number of U- sutures was recorded. The procedure was also performed on three client-owned rams with unilateral non-strangulated IH and the occurrence of re-herniation was followed up. In cadavers, LAPS of the IIRs could be easily and satisfactorily performed with either of the two systems, requiring one to three U-sutures per IIR. No differences were observed between the two surgical procedures. In two clinical cases, the procedure was successfully performed without reoccurrence of herniation or alterations in reproductive behavior in the following 3 and 6 months. In the third case, the hernia was reduced but a retroperitoneal emphysema during laparoscopy prevented hernioplasty and the animal herniated again. In conclusion, LAPS of IIR can be used as a simple and feasible treatment to preserve testicles in rams with IH

    Metodología jerárquica h adaptativa basada en subdivisión de elementos

    [EN] This paper presents a hierarchical h adaptive methodology for Finite Element Analysis based on the hierarchical relations between parent and child elements that come out if these elements are geometrically similar. Under this similarity condition the terms involved in the evaluation of element stiffness matrices of parent and child elements are related by a constant which is a function of the element sizes ratio (scaling factor). These relations have been the basis for the development of a hierarchical h adaptivity methodology based on element subdivision and the use of multipoint-constraints to ensure C0 continuity. The use of a hierarchical data structure significantly reduces the amount of calculations required for the mesh refinement, the evaluation of the global stiffness matrix, element stresses and element error estimation. The data structure also produces a natural reordering of the global stiffness matrix that improves the behaviour of the Cholesky factorization.[ES] En este artículo se presenta una metodología h adaptativa para el Análisis por Elementos Finitos basada en las relaciones jerárquicas entre elementos padre e hijo que surgen si estos elementos son geométricamente similares. Bajo esta condición de similitud, los términos resultantes de la evaluación de las matrices de rigidez de elementos padre e hijo están relacionados por una constante que es una función de la relación de tamaños de elemento (factor de escala). Estas relaciones han sido la base para el desarrollo de una metodología jerárquica h adaptativa basada en la subdivisión de elementos y el uso de restricciones multipunto para asegurar la continuidad C0 . El uso de una estructura de datos jerárquica reduce significativamente la cantidad de cálculos requeridos para el refinamiento de la malla, la evaluación de la matriz de rigidez global, las tensiones de los elementos y la estimación del error del elemento. La estructura de datos también produce un reordenamiento natural de la matriz de rigidez global que mejora el comportamiento de la factorización de Cholesky.The authors wish to thank the Spanish Ministerio de Economía y Competitividad for the fiancial support received through the project DPI2013-46317-R and the Generalitat Valenciana through the project PROMETEO/2016/007.

    Multiple-criteria cash-management policies with particular liquidity terms

    Full text link
    [EN] Eliciting policies for cash management systems with multiple assets is by no means straightforward. Both the particular relationship between alternative assets and time delays from control decisions to availability of cash introduce additional difficulties. Here we propose a cash management model to derive short-term finance policies when considering multiple assets with different expected returns and particular liquidity terms for each alternative asset. In order to deal with the inherent uncertainty about the near future introduced by cash flows, we use forecasts as a key input to the model. We express uncertainty as lack of predictive accuracy and we derive a deterministic equivalent problem that depends on forecasting errors and preferences of cash managers. Since the assessment of the quality of forecasts is recommended, we describe a method to evaluate the impact of predictive accuracy in cash management policies. We illustrate this method through several numerical examples.Salas-Molina, F.; Pla Santamaría, D.; Garcia-Bernabeu, A.; Mayor-Vitoria, F. (2020).
