Abstract: People from all age groups and social backgrounds have always sought to learn swimming. However, the swimming learning process is usually considered repetitive and tiring, requiring the teacher to use methods that motivate students to join the practice without ignoring the need for improvement in their performance. This study assessed motivation during a breaststroke learning process in students who received videotape feedback, verbal feedback, and who did not receive any feedback during practice. Thirty seven swimming inexperienced students were divided into three groups: Video (n=13), which received videotape feedback; Verbal (n=15), which received verbal feedback; and Control (n=9), which did not receive any feedback during experimental phases (pre-test, acquisition (5 days), post-test and retention). Participants completed a questionnaire based on Likert scale for motivation assessment. Scores were given to their performance by a swimming teacher to assess breaststroke learning during each experimental phase. Results of motivation assessment showed that students who received feedback (videotape or verbal) felt more motivated during practice than those who did not receive any feedback. Regarding the breaststroke learning, all participants improved their performance along experimental phases, but, during the retention one, Verbal group’s performance was considered superior to the Control group’s performance. This study concluded that the use of videotape and verbal feedback has motivational results on breaststroke learning, and that it is effective in the learning process.

Abstract: the objective of this investigation was to estimate ideal bands of respiratory rate and cloacal temperature for broiler chicken strains during the rearing period and to evaluate the influence of time of exposure on bird physiological variables under different thermal stress conditions. the research was conducted in a climatic chamber during the six weeks of the rearing period, with avian and cobb strains exposed to two climatic conditions (comfort and stress), in three distinct times of exposure, in three conditions (before going to the chamber; at the end of exposure time; 30 minutes after the end of exposure), in four treatments: comfort with 60 minutes of exposure; stress with 30 minutes of exposure; stress with 60 minutes of exposure; stress with 90 minutes of exposure. bands of respiratory rate and cloacal temperature were elaborated for both strains, for each one of the weeks of the rearing period. strains differed, regardless of treatments and conditions adopted in the research on the third, fifth and sixth weeks of life in relation to the cloacal temperature. the cobb strain is more tolerant to thermal stress in comparison with the avian. there was difference for both variables between comfort and stress, but time of exposure to stress did not influence the physiological response of birds, except for cloacal temperature on the second week of life.

Abstract: a method for aflatoxin m1 determination in milk by thin layer chromatography was otimized and in house validated. steps of extraction, clean-up, detection and quantification by visual and densitometric analysis were standardized. in method validation were employed standard solutions and spiked samples in levels varying from 0.027μg/l to 0.970μg/l. linearity, specificity, trueness, precision, detection and quantification limits were the parameters evaluated. average recovery values in quantification range were from 84.2% to 99.0% for visual analysis and from 85.2% to 105.2% for densitometric analysis, with cvs values from 2.3% to 9.8% and from 3.6% to 13.9%, respectively. the detection limit was 0.036μg/l and the quantification 0.045μg/l, according to national and international regulations for aflatoxin m1 in milk.

Abstract: background: resting heart rate (which ranges from 60 to 80 bpm) is one of the simplest cardiovascular parameters, and has been considered as a predictor of cardiovascular and all-cause mortality. objective: to determine the predictive value of resting heart rate (rhr) before exercise stress testing (et) for cardiovascular (cv) and all-cause mortality. methods: this was a case-control study using data from the database of the exercise testing laboratory of a cardiac hospital and the death records of the health department of a city located in the south of brazil from january 1995 to june 2007. a total of 7,055 patients were studied; 1,645 (23.3%) in the case group (deceased) and 5,410 (76.7%) in the control group (alive). the cut-off value of rhr for mortality was derived from the roc curve, and a multivariate analysis was performed for the selected variables. the study's outcome measures were cardiovascular and all-cause mortality. results: six hundred and seventy-four patients died of cardiovascular diseases (9.5%); the cut-off value was rhr > 78 bpm). after adjusting for selected variables, the odds ratio (or) of rhr > 78 bpm was 3.5 (95% ci 2.9 to 4.2) for cv mortality and 3.6 (95% ci 3.2 to 4.0) for all-cause mortality. conclusion: resting heart rate > 78 is an independent predictor of cardiovascular and all-cause mortality.

Abstract: although oral health policy in the city of diadema, s?o paulo, brazil, from 1972 to 2007, the subject of this article, has accompanied the process of transformation of the sector's practices in brazil, its evolution in this industrial city located in the metropolitan region of s?o paulo has been marked by the singularity of the local history. this paper analyzes this evolution and relates it to the process of social struggles that led to the creation of the sistema único de saúde (brazil's national health system) and to the national, state and local oral health policies. this is a qualitative exploratory study. data were obtained from official documents and various literature sources and also through semi-structured interviews with mayors, municipal health secretaries, oral health coordinators and dentists who have undergone the various stages of the oral health policies in the municipality. the major features in the organization of health care practices developed in the city were identified, locating them in the state and national scenario. we conclude that, despite the consolidation of the integration of oral health in the sus and the experience acquired in the city in managing this type of care, in diadema we also observed difficulties to overcome the model of care focused on population groups which have been traditionally prioritized, with emphasis on school children, preschoolers and babies. in this sense, diadema shares with other brazilian cities the challenge of restructuring primary care in oral health, overcoming the traditional model of school dentistry and creating new possibilities, such as the family approach, in order to ensure the universality and comprehensiveness of care.

Abstract: pregnant sows confinement systems were created in order to maximize the productivity, however there are problems concerning the animal welfare. the aim of this research was to evaluate pregnant sows in outdoors and in confinement systems in relation to the thermal environment and physiological animal responses. the experiment was conducted in a commercial farm in monte mor city, s?o paulo, brazil. the physiological evaluation was performed by recording physiological variables, such as respiratory frequency and skin temperature. furthermore, variables like dry bulb temperature, wet bulb temperature, and black globe temperature were also evaluated to characterize the ambient by means of enthalpy and black globe humidity index. in each treatment six animals were evaluated. the experimental design was completely randomized in a split-plot version whose averages were compared by the tukey test. the findings of the experiment revealed higher values for all the bioclimatic variables in the confined treatment. hence, the outdoor system provided better thermal conditioning for pigs, resulting in a lower heat stress.
