Avaliação do processo de intervenção com professores para prevenção a problemas de comportamento infantil

Objective The prevalence of emotional and behavioral problems reaches 30% of school-age Brazilians. Management by teachers can reinforce such difficulties and, therefore, it is essential to assess interventions to provide them with the best tools available. In this study, it was aimed to present the development and implementation of the Facilitating Contact with Students Program was implemented in early grade teachers. Method The process of two modalities of this Program was evaluated: G1 (with a full program) and G2 (with a partial program, without the cognitive model contents, only instruction about behavioral management techniques and socioemotional support). Results The G1 gave better scores to the intervention on the importance and usefulness of the contents. Conclusion The teacher’s knowledge regarding the cognitive model is relevant for the modification of disruptive behaviors of students in the classroom.Objetivo A prevalência de problemas emocionais e de comportamento chega a 30% em brasileiros em idade escolar.

Polycaprolactone/Starch/Agar Coatings for Food-Packaging Paper: Statistical Correlation of the Formulations’ Effect on Diffusion, Grease Resistance, and Mechanical Properties

Paper is one of the most promising materials for food packaging and wrapping due to its low environmental impact, but surface treatments are often needed to improve its performance, e.g., the resistance to fats and oils. In this context, this research is focused on the formulation of a new paper bio-coating. Paper was coated with liquids containing poly(hexano-6-lactone) (PCL), glycerol and variable percentages of starch (5–10% w/w PCL dry weight), agar-agar (0–1.5% w/w PCL dry weight), and polyethylene glycol (PEG) (5% or 15% w/w PCL dry weight) to improve coating uniformity and diffusion. A design of experiments approach was implemented to find statistically reliable results in terms of the best coating formulation. Coated paper was characterized through mechanical and physical properties. Results showed that agar content (1.5% w/w PCL dry weight) has a beneficial effect on increasing the resistance to oil. Furthermore, the best coating composition has been calculated, and it is 10% w/w PCL dry weight of starch, 1.5% w/w PCL dry weight of agar, and 15% w/w PCL dry weight of PEG

TRANSLATE -- A Monte Carlo Simulation of Electron Transport in Liquid Argon

The microphysics of electron and photon propagation in liquid argon is a key component of detector design and calibrations needed to construct and perform measurements within a wide range of particle physics experiments. As experiments grow in scale and complexity, and as the precision of their intended measurements increases, the development of tools to investigate important microphysics effects impacting such detectors becomes necessary. In this paper we present a new time-domain Monte Carlo simulation of electron transport in liquid argon. The simulation models the TRANSport in Liquid Argon of near-Thermal Electrons (TRANSLATE) with the aim of providing a multi-purpose software package for the study and optimization of detector environments, with a particular focus on ongoing and next generation liquid argon neutrino experiments utilizing the time projection chamber technology. TRANSLATE builds on previous work of Wojcik and Tachiya, amongst others, introducing additional cross-section processes up to ionization, thus modeling the full range of drift electron scattering interactions. The simulation is validated by benchmarking its performance with swarm parameters from data collected in experimental setups operating in gas and liquid.Comment: 17 pages, 12 figure

Interventions with teachers to adjust child behavior : a systematic review of the literature

Problemas de comportamento denotam preocupação na educação infantil, pois afetam a aprendizagem, configurando-se como preditores de dificuldades futuras nos âmbitos social, cognitivo e acadêmico. Entretanto, há intervenções que visam promover práticas docentes que buscam preveni-los ou modificá-los. Nesse sentido, revisou-se a literatura para identificar os procedimentos metodológicos envolvidos na avaliação de processo e resultados de intervenções voltadas aos professores da educação infantil, visando o ajustamento comportamental de seus alunos. Adotou-se a diretriz PRISMA e PICO, pesquisando os descritores problem behavior, classroom, children, intervention e teacher nas bases Ebsco, APA PsychNET, Web of Science e BVS. Foram elegidos 17 estudos publicados nos últimos 10 anos em língua inglesa. Evidenciou-se a escassez de pesquisas brasileiras sobre intervenções nessa temática e o não estabelecimento de uma metodologia experimental. Ainda, uma minoria avaliou o processo da intervenção e, entre estes, apenas alguns explicitaram a metodologia utilizada.Behavior problems and deficits in social skills have been a concern in early childhood education because these affect learning and are predictors of future problems in the social, academic and cognitive settings. However, there are interventions aimed to promote teaching practices that have resulted in greater behavioral adjustment of students. The success of these programs is related to factors intrinsic to their implementation and evaluation. We sought to identify the methodological procedures involved in the evaluation of the process and results of interventions address at preschool teachers, aiming at the behavioral adjustment of the students.

Snoring in a cohort of obese children: association with palate position and nocturnal desaturations

Purpose of the study: Frequency of habitual snoring is significantly higher in obese than in normal-weight subjects. Obesity and adeno-tonsillar size are risk factors of snoring. Other factors, such as fat distribution and upper airway collapsibility, could explain the relationship between obesity, snoring and obtructive sleep apneas. The aim of the study was to investigate clinical and instrumental significance of snoring in exogenous obese children referred to our department.Methodology: This preliminary study takes part of a larger prospective respiratory sleep study. In 36 consecutive obese children (18 males), bodymass index (BMI), BMI Z score and neck circumference were calculated according to age and sex. Nasal patency, tonsil size, palate position scoring were also recorded. An overnight polygraphy was performed using a portable ambulatory device. Statistical analysis was done using SPSS® Statistics 19.0 software for Windows®.Main findings: Snoring, objectively measured by polygraphy, was associated with palate position and with oxygen desaturation index (ODI). The correlation between snoring and ODI completely disappeared when adjusting for palate position scoring.Key conclusions: Low palate position can be identified as an adjunctive, although not unique, factor that can contribute to making snoring and increased desaturation events possibly related to increased risk of upper airway collapsibility during sleep in obese childre

Successful weight loss maintenance in relation to method of weight loss

This study examined the relation between method of weight loss and long-term maintenance among successful weight losers enrolled in a weight-loss maintenance trial. Participants were 186 adults (mean age = 51.6 +/- 10.7 years, mean BMI = 28.6 +/- 4.7 kg/m(2)) enrolled in the STOP Regain trial who had lost at least 10% of their body weight in the past 2 years using a very low-calorie diet (VLCD; n = 24), commercial program (n = 95), or self-guided approach (n = 67). Participants were randomized to a weight-maintenance intervention delivered face to face or over the internet or to a newsletter control condition, and followed for 18 months. At study entry, individuals who had used a VLCD had achieved a weight loss of 24% of their maximum weight within the past 2 years compared to 17% achieved by those who had used a commercial program or self-guided approach (P \u3c 0.001). However, individuals who had used a VLCD regained significantly more weight than the other two groups and by 6 months, there were no significant differences in overall percent weight loss (i.e., initial weight loss and maintenance) between VLCD, commercial, and self-guided methods. In contrast, individuals who had used a self-guided approach maintained their weight losses from baseline through 18 months. The large initial weight losses achieved by individuals who had used a VLCD were not maintained over time, whereas individuals who had used a self-guided approach maintained their initial weight losses with the greatest success. The generalizability of these findings is limited by the sizeable weight losses achieved by study participants
