Elementos psicomotores e fatores sociais relacionados ao desenvolvimento motor e dificuldades de aprendizagem em crianças ingressantes no ensino fundamental

In humans, psychic and motor skills are interdependent, and therefore, cannot fail to take into account the influence of a good psychomotor development in the prevention of learning difficulties. Another factor that interferes with the learning process is the social. Family problems, socioeconomic status of the child, among others, may be associated with learning difficulties and, consequently, the student's performance. Therefore, the aim of this study was to investigate through the elements of psychomotor, if a delay in neuropsychomotor development may be related to the presence of learning problems in children entering elementary school. Also, determine whether there were differences regarding the presence or absence of these difficulties in students from middle and low social class and have family problems or not. For this, we analyzed two classes of 49 students from 1 year of elementary education at a public school in the city of Bauru/SP, aged between 6 and 7 years. These students were tested for the ENE proposed by Lefèvre (1976) to assess the maturity of the nervous system. A pre-designed questionnaire was answered by the teachers of classes to know students' academic performance, learning difficulties presented by them, social status and the presence of family problems. All students participating in the survey had the term sheet signed by the parents, allowing participation in the study. To reach the results, we applied the Anova and Tukey test for comparison analysis of mean age in the performance of ENE. To investigate the existence of a relationship between performance in the ENE and learning difficulties, we used the calculation of Pearson correlation. To analyze the difference in average scores of learning disabilities in students from different social classes and among those who had family problems or not, comparative graphs were used with the averages obtained from the questionnaire answered by the teachers for each learning...

Effect of composite surface treatment and aging on the bond strength between a core build-up composite and a luting agent

Objective: The purpose of this study was to assess the influence of conditioning methods and thermocycling on the bond strength between composite core and resin cement. Material and Methods: Eighty blocks (8x8x4 mm) were prepared with core build-up composite. The cementation surface was roughened with 120-grit carbide paper and the blocks were thermocycled (5,000 cycles, between 5 degrees C and 55 degrees C, with a 30 s dwell time in each bath). A layer of temporary luting agent was applied. After 24 h, the layer was removed, and the blocks were divided into five groups, according to surface treatment: (NT) No treatment (control); (SP) Grinding with 120-grit carbide paper; (AC) Etching with 37% phosphoric acid; (SC) Sandblasting with 30 mm SiO2 particles, silane application; (AO) Sandblasting with 50 mu m Al2O3 particles, silane application. Two composite blocks were cemented to each other (n=8) and sectioned into sticks. Half of the specimens from each block were immediately tested for microtensile bond strength (mu TBS), while the other half was subjected to storage for 6 months, thermocycling (12,000 cycles, between 5 degrees C and 55 degrees C, with a dwell time of 30 s in each bath) and mu TBS test in a mechanical testing machine. Bond strength data were analyzed by repeated measures two-way ANOVA and Tukey test (alpha=0.05). Results: The mu TBS was significantly affected by surface treatment (p=0.007) and thermocycling (p=0.000). Before aging, the SP group presented higher bond strength when compared to NT and AC groups, whereas all the other groups were statistically similar. After aging, all the groups were statistically similar. SP submitted to thermocycling showed lower bond strength than SP without thermocycling. Conclusion: Core composites should be roughened with a diamond bur before the luting process. Thermocycling tends to reduce the bond strength between composite and resin cement.

Natural and anthropogenic influence on soil erosion in a rural watershed in the Brazilian southeastern region

Human activities have been driven land cover, provoking acceleration of the erosive process and alteration on the soil characteristics. To explore the effects of human disturbance, we investigated the influences of natural and anthropogenic features on soil quality and soil erosion indicators (EI) within a Brazilian rural watershed located in Bauru Municipality, State of So Paulo. A pre-established set of soil EI was used to evaluate the influence of anthropogenic land cover categories on the presence and severity of erosion, related with spatial variations of soil attributes. On-site visits were carried out to measure the occurrence and the intensity of eleven separate EI values and to collect undisturbed topsoil samples for subsequent analyses. We registered 17 occurrences of EIs, distributed in ten locals. Occurrence and intensity of EIs were related to degree of sheet erosion. The EI qualities were more strongly associated with land cover management practices than to local topographic features. The occurrence of EIs and characteristics of soil and soil organic matter (SOM) were not significantly self-correlated. Although land cover class seems to influence soil properties and SOM attributes, we observed that the granulometric composition of the soils also contributes to the structural characteristics of the soil and consequently to the dynamic loss and gain of soil carbon. Sites covered with natural remnant vegetation (NRV) store 96.5 Mg ha(-1) of C and grassy and tilled soils stored more C than NRV, 100.1 and 142.4 Mg ha(-1), respectively. Due to the influence of soil texture over the soil C dynamic, we observe that in Bauru, pastured areas have high potential for sequestration of C if factors such as fire and/or erosion were avoided or effectively controlled. Results from this study show that human disturbance substantially affects soil properties within of southeastern region of Brazil.

Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups

Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This article presented and discussed the indications and limitations of enamel microabrasion treatment. Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups.

Resistance to tetracycline and β-lactams and distribution of resistance markers in enteric microorganisms and pseudomonads isolated from the oral cavity

This study evaluated the occurrence of enteric bacteria and pseudomonads resistant to tetracycline and beta-lactams in the oral cavity of patients exhibiting gingivitis (n=89); periodontitis (n=79), periodontally healthy (n=50) and wearing complete dentures (n=41). Microbial identification and presence of resistance markers associated with the production of beta-lactamases and tetracycline resistance were performed by using biochemical tests and PCR. Susceptibility tests were carried out in 201 isolates of enteric cocci and rods. Resistance to ampicillin, amoxicillin/clavulanic acid, imipenem, meropenem and tetracycline was detected in 57.4%, 34.6%, 2.4%, 1.9% and 36.5% of the isolates, respectively. beta-lactamase production was observed in 41.2% of tested microorganisms, while the most commonly found beta-lactamase genetic determinant was gene bla(TEM). Tetracycline resistance was disseminated and a wide scope of tet genes were detected in all studied microbial genus.

O desenho-estória na atenção psicológica a crianças na fase pré-cirurgica

The hospitalization process generates stress and, for a child who has already experienced a surgery can suffer from threatening, anxiety and distress. This search examines the experiences of children indicated for different craniofacial surgery which in many cases require more than esthetic or reconstructive surgery. It is quantitative and qualitative study, descriptive and comparative. The sample is intentional and it is made up of ten children, five boys and five girls in the pre-surgical Hospital for Rehabilitation of Craniofacial Anomalies HRAC-USP, Bauru-SP. As a tool for data collection, the design-themed story and data are used from subsequent survey developed by Walter Trinca. The results indicate that the design-themed story is suitable for the identification of the kid's childhood experiences in helping to deal with the stressful situation. Some of the children reveal their feelings of anxiety and fear and manifest other defenses such as denial. In all cases it identifies emotional states of concern such as anxiety and fear, or also denial of those feelings. It was concluded by the need of creating more favorable conditions in order to identify and address childhood experiences compared to surgery in a hospital environment, proposing the designthemed story technique that reveals those experiences. It emphasizes the relevance of psychological intervention in the hospital environment, considering childhood fantasies and feelings that generate or intensify emotional states of anxiety, fear and distress in pre-surgical level.

Políticas públicas e direitos de crianças e adolescentes: o papel da mídia na expansão da cidadania

This paper presents results of an evaluation of the quality of the coverage of issues associated to the preservation of rights of children and adolescents in the eight main newspapers of major cities of Bauru (Sao Paulo State) administrative region, from August 2008 to March 2009. In a total of 389 assessed stories, 66% portrayed acts of legal infraction and violence with children and adolescents as victims or perpetrators, with a fragmented and superficial perspective; 34% are greater approaches about public policies aimed at the preservation of social rights. The results show the existence of a smaller number, yet significant, of stories which presented extended and more contextualized approaches. From a general view, we can point out that the contribution given by the media as a form of vigilance over the execution of public policies has been limited, which justifies the concern of demanding, from the mass media, measures to fulfill the role attributed to them by contemporaneous democracies to the strengthening of citizenship.
