Validação do instrumento de avaliação do jogador de futebol em situação de jogo

In the literature, it is possible to find a large number of studies directed toward athletic training in the physical, technical and tactical aspects of the Soccer game. In the other side, we are able to attest that there exists few instruments in the sport area of studies on evaluation of the athlete, in specific, rare are the instruments for assessment that takes into consideration the game situation. The most important aspect of an instrument of assessment is its validity. The present study has the objective to validate the “Instrument for Assessment of the Soccer Player” (IASP), proposed by Gama (2003). For the process of validation, participated nine university students, volunteers, four women and five men. The evaluators had a training period for acquaintance with the instrument and they analyzed, in individual basis, soccer games registered in video. This procedure was done via a 29 inches TV set, a DVD device and a voice recorder. Tests of reliability and objectivity were applied in order to measure intra and between observers consistency. As for the objectivity analysis, the results for each one of the soccer motor action with the ball in a game situation showed high correlation between possible score and obtained score. However these data did not allow for the validation of the IASP instrument as the criterion applied to the analyzed actions were different between observers even when of the observation of the same player in the same game. This problem was detected also in the evaluation of reliability. However, the present study was capable to point out inconsistencies within the Instrument for Assesment of the Soccer Player (IASP) so that after the needed changes being made, another validation will be done

Influência do uso de hipoclorito de sódio 2,5% e extrato glicólico de sálvia 20% durante o preparo biomecânico sobre a resistência adesiva de retentores intra- radiculares: avaliação através do teste de push-out

The aim of this study it was to evaluate the use of irrigating solution used during root canal preparation on the adhesive cementation of prefabricated fiberglass pins. The bond strength between different regions of the root and the fiberglass pins cemented into the root canal were evaluated by push-out assay. For this study, 36 human teeth were used, all equally prepared. The irrigating solutions used for biomechanical preparation were: saline solution, sodium hypochlorite 2,5% and glycolic extract of salvia 20%. The dual cure resin cement was used for cementation of pins. After cementation, specimens were sectioned to give 3 slices of approximately 2 mm each (cervical, middle and apical), which were submitted to mechanical push-out test. Were performed ANOVA and Tukey's test with a significance level of 5%, for the analysis of mechanical test. Comparing the thirds we observed that the only solution that presented statistical difference in the bond strength was sodium hypochlorite, which showed higher values for the middle and apical third compared with the cervical third, but when compared without taking into consideration the dental thirds, solutions studied showed no differences in bond strength. Therefore, it was concluded that the solutions studied can be used during endodontic treatment without causing harmful effects on the final adhesive restoration

Avaliação da toxicidade sobre Ceriodaphnia dubia das águas dos rios Atibaia, Jaguari e efluente tratado de refinaria de petróleo

Ensuring availability of quality water for human consumption causes becomes an increasing number of studies for the analysis of effluent before and after treatment, so that its release into receiving bodies do not cause significant changes in the river water and on the biological communities related to them. The biomarkers of toxicity have long been used to verify the potential toxic effluent and its correlation with the treatment efficiency of them. In this context, the cladoceran Ceriodaphnia dubia stands out because it is a benthic aquatic organism highly sensitive to environmental changes. In this study, to evaluate the interference of the release of treated wastewater of oil refinery in Rio Atibaia, we sought to determine the toxicity on population dynamics of Ceriodaphnia dubia microcrustacean in water samples upstream and downstream from the launch site, compared with samples from Rio Jaguarí at the point of capture by the company itself and treated effluent. We have studied the number of offspring produced in 10 replicates, each starting with a test individual of up to 24 hours for each sample and correlated the results with physical-chemical and microbiological tests performed by a laboratory technician. For most tests, the results indicate that the treated effluent gives sub-lethal toxicity to the microcrustacean, as delay the onset of the reproductive cycle of the same

Desenvolvimento e avaliação das atividades antioxidante e despigmentante in vitro de emulsões múltiplas a/o/a contendo dipalmitato kójico

Currently, there has been a growing concern for men and women with the appearance of the face and body, driven primarily by aesthetic standards set by the media. For this, the pharmaceutical and cosmetic industries have conducted numerous research projects aiming at the development of formulations that mitigate the aging and some skin disorders such as hipercromies. One of the most frequent pathologies of skin is melasma, a manifestation of hyperpigmentation caused by hipermelanogenesis symmetrical and progressive, caused usually by hormonal irregularities, exposure to sunlight and genetic factors. In addition to sunscreen, the treatment is indicated the use of depigmenting substances, among them the kojic dipalmitate (DK), which is cleaved into kojic acid (5- hydroxy-2-hydroxy-methyl-4H-piran-4-one) by esterase after absorption by the skin cells. The kojic acid inhibits the action of tyrosinase as a chelator of ions and promotes the reduction of eumelanin and its precursor monomer. To promote a controlled release and improve the stability of the system, the DK can be incorporated into multiple emulsions, that is, complex systems composed of two emulsifications, where the two types of emulsions (W/O and O/W or O/W and W/O) exist simultaneously, forming emulsions of type W/O/W or O/W/O. This work aimed to incorporate the DK in emulsion W/O/W, physical-chemical systems obtained and to evaluate the antioxidant and depigmenting action in vitro of the developed formulations. The physico-chemical characterization was performed by microscopic analysis, quantification and size distribution, determination of pH, conductivity, zeta potential and bioadhesive test of the formulations. The droplet size in accordance with the use of light microscopy and dynamic light scattering is approximately 1μm. The pH, electrical conductivity and bioadhesion have not changed with the addition... (Complete abstract click electronic access below)

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Avaliação da produtividade no trabalho organizado em turnos em uma empresa vidreira

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

Avaliação dos efeitos citotóxicos, genotóxicos e mutagênicos do fipronil, após fotodegradação, utilizando Allium cepa como organismo teste

Compounds released into the environment can induce genetic alterations in living organisms. A group of chemicals that shows proven toxicity is the pesticides, and the insecticides are the most harmful. The insecticides of the family phenylpyrazole have wide application both in agriculture and in homes. Fipronil, an insecticide of this chemical group, is widely used in various cultures and in homes, mainly for fighting fleas and ticks on dogs and cats. The use of fipronil may represent a risk to man and the environmental health, since this pesticide can potentially induce cell death, regardless of cell type. Fipronil, when in contact with the environment, can undergo various degradation processes, including photodegradation. The toxic effect of one of its metabolites derived from photodegradation, sulfone-fipronil, is approximately 20 fold as great as fipronil itself. The A. cepa test system was used to evaluate cytotoxic, genotoxicity and mutagenic effects of fipronil before and after phptodegradation. Seeds of Allium cepa were subjected to solutions of fipronil, pre-exposed or not exposed to degradation by sunlight. The germination tests were conducted both under the effect of light and in the dark. We evaluated the cumulative potential of this insecticide using 48 and 72-hours recovery tests. The results showed that when fipronil was previously exposed to the sun, it presented a greater genotoxic and mutagenic potential, showing that the metabolites formed by photodegradation can show more harmfull effects

Avaliação das características físico-químicas e microbiológicas dos componentes fibrosos obtidos da moagem úmida de grãos de milho

Fibers are non-digestible materials by human organism, and they are insoluble in specific conditions. The corn fiber has been used as an alternative to enrich the food products for human consumption, in order to add nutritious value to this co-product. This study aimed at determining the chemical and fractions components of corn fiber, extracted by semi-wet milling in laboratory (LabF), and by semi-humid milling in industrial process (IndF); and microbiological analyses were perform in the last fraction. The fiber composition differed significantly among these two products as to moisture, ash, lipids, proteins, insoluble dietary fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and lignin contents. The sample IndF showed microbiological parameters in compliance with the specifications for consumption. The investigated corn fiber may effectively contribute to increase the fiber intake in the diet. As the industrially processed fiber (IndF) showed compliant microbiological parameters with the specifications for food, this component might be incorporated into the food products formulation.
