The practice of childhood sedentary lifestyle is a complex problem that evokes a public health concern. This article exposes a work field in which researches identify, describe and analyze verbal reports about effective contingencies at school. It introduces the practices of three teachers of physical education and their 62 students. The results suggest that actions that can support public policies toward mitigating health risks.

Sintomas e condutas vocais na perspectiva de educadores atuantes no ensino fundamental

The objective of the present study was to identify previous and current vocal symptoms and to verify the behaviors ahead of the symptoms. Moreover, the gotten relations between the professional profile and data had been searched. 78 teachers had participated of the research, being two men and 76 women. Questionnaire was applied. In this questionnaire was elaborated on the basis of previous research and it contained questions on vocal health. The results to indicate that were evidenced one high (48%) frequency of the teachers had makes intense use of the voice at least has ten years. This study it allowed to conclude that it is necessary to modify the focus of interventions directed toward these professionals therefore has some factors in the work routine that intervene with its general and vocal health. Therefore interventions in the individual field are only insufficient to decide the problem.

Detecção de Salmonella Enteritidis em ovos de codornas japonesas submetidas a dietas com diferentes níveis de cálcio e fósforo

The eggs are pointed in several studies as the main cause of human salmonellosis. Have been identified that eggs are eaten raw or poorly processed are mainly responsible for outbreaks of human infection with Salmonella spp. Besides causing problems to public health, the presence of bacteria impedes or hinders the international food trade, as a sanitary barrier. Several factors predisposing to contamination of the internal contents of eggs for Salmonella spp., including the egg shell quality (shell quality), which is related to levels of calcium (Ca) and phosphorus (P) in the diet of quails . The experiment used eggs of Japanese quail under different diets containing two levels of Ca (2.0 and 3.5%) and two levels of available P (0.25 and 0.45%). Eggs of 120 japanese quails were divided into four treatments with three replicates. The experiment was divided into three production stages: initial, intermediate and final. Were assessed at each stage the presence of bacteria in internal and external content of experimentally contaminated eggs during periods of 0, 24, 96 and 168 hours after immersion in broth containing Salmonella Enteriditis. Salmonella Enteriditis was detected in the shell during all periods of storage, in decreasing amounts in all treatments. None of the treatments within the three production stages analyzed, we detected significant amounts of the bacteria inside the egg, in our experimental conditions. Therefore, the levels of Ca and P in the diets of quail do not determine higher or lower risks to public health represented by eggs

Emprego de soluções homeopáticas derivadas de ácido salicílico e ácido gigerélico no enraizamento de estação de hortelã (Mentha spicata L.)

Os riscos à saúde e os altos custos do uso de agrotóxicos e de outras substâncias que favoreçam a produção agrícola têm dado espaço para a Homeopatia atuar como mecanismo alternativo no controle de pragas e incremento na agricultura de sustentabilidade. Diversos trabalhos e experimentos, tradicionais e atuais, enfatizam a importância e a eficácia desta alternativa também à saúde dos humanos e dos animais. O uso de modelos vegetais nos estudos homeopáticos contribui para o entendimento dessa afirmação, pois o efeito placebo passa a não considerado. O objetivo deste trabalho foi verificar os efeitos das soluções homeopáticas derivadas de cristais de ácido giberélico e de ácido salicílico no enraizamento de estacas de hortelã (Mentha spicata L.). Estacas recém-formadas foram mergulhadas em soluções tratamento nas potências 6CH, 12CH, 18CH, 24 CH e 30CH com aplicação única ou suplementar; como testemunhas foram empregadas soluções de etanol 30% não dinamizado, etanol 30% dinamizado e água desmineralizada. Os resultados mostraram que as soluções derivadas do ácido salicílico promoveram melhores resultados que as soluções oriundas do ácido giberélico e dos tratamentos controle. Este aspecto concorda com a prática homeopática como um todo, pois o ácido salicílico é considerado agente inibidor das reações fisiológicas relacionadas com o enraizamento de estacas. Além disso, foi importante detectar que o uso de soluções homeopáticas em regime de dose única trouxe melhores resultados do que o seu uso contínuo

Tratamento orgânico de resíduos de rúmen bovino

The organic wastes need to be adequately managed, in order to avoid the environmental pollution and damage to the public health. So, this work aimed to study the composting process using two methods: manual and mechanized, for the treatment of bovine ruminal waste. This residue is generated in large proportions during the bovine slaughter process, and it can lead environmental degradation and contamination, or even damage to the public health, when not treated. For the initial adjustment of the composting parameters, it was incorporated the residue of coffee husks. The manual composting system was done by the manually aerated piles, while the mechanized composting system was done in a reactor coupled to a compressor that enabled the aeration of the system. The proportions used in both systems were: 90% bovine rumen (R) and 10% coffe husks (CC); 85% bovine rumen and 15% coffe husks; 80% bovine rumen and 20% coffe husks. The parameters determined during the monitoring of the composting process were: temperature, pH, moisture, organic matter, ash, organic carbon, Kjeldahl nitrogen and C/N ratio. The results obtained during the monitoring of the piles and reactors presented similar behavior, except for the parameters Kjeldahl nitrogen and C/N ratio. When compared to the “Instrução Normativa no 25 de 23/07/2009 do Ministério da Agricultura, Pecuária e Abastecimento”, the organic produced composts with the best results were: pile 2 (85% R; 15% CC) and reactors 1 (90% R; 10% CC) e 2 (85% R; 15% CC)

Análise da qualidade microbiológica em leite pasteurizado, tipo C, recém pasteurizado e na data de validade

The conservation of raw milk for long periods of time under refrigeration can result in the lost of its quality. This happens because bacterias, capable of developing in low temperatures, as psichrotrophics, in milk, associates with its enzymatic activities, are capable to degradate it. Although the pasteurization of milk sufficiently diminishes the transmission of the illnesses, that generally eliminates such microorganisms, is not a total efficient process because many enzymes produced for such bacterias are termostable, being able to resist the treatment and to remain active, leading to the loss of the quality of milk and its derivatives. The Normative Instruction 51 of 2002 established that milk must be cooled and stored in the production property, what resulted increasing the incidence of such bacteria in population destined milk. In some parts of the world contaminated milk is causing serious risks to the health of the population, assuming great importance in Public Health, mainly in relation to the hygienic-sanitary conditions of the product. ANVISA establishes, thus, maximum bacteriological concentration that must be evidenced before commercializing the product, guaranteeing the quality of milk as proper for consumption. Based on these aspects, the objective of this work is the microbiological analysis of 30 milk samples type C, collected in bakeries of the city Botucatu, in the state of São Paulo. Analysis were made to determinate the most likely number of termotolerants coliforms, as well the number of colony units of psichrotrophics bacterias, the presence of Salmonella and the enumeration of positive Staphylococcus aureus, at the moment of purchase and validity of the products

Estudo da elaboração do plano de descomissionamento para desativação de empreendimentos

Deconstructions, although hardly covered in Civil Engineering courses, are a very important field of study. Due to numerous factors, such as obsolescence, buildings life cycle comes to an end leading to their deactivations. Decommissioning is a process that intends to plan the hole deactivation by providing the cleaning of contaminated areas, avoiding risks to public health, as well as promoting a screening of generated waste, whether dangerous or not, offering their correct disposal or even reuse when possible. Decommissioning must be developed by a plan that covers from the recognition of the area until its releases to other uses. When this procedure is appropriate, attention must be paid to the cost effective of its implementation and to the cleaning standard that the plan intends to reach. The execution of the service allows to reuse the area, becoming productive again

Estudo da concentração de material particulado em ambientes internos e externos de bibliotecas

Our twenty-first century society and the rhythm of life and work we have to face in our daily routine compel us to spend most of our lifetime in closed environments, in our houses, educational institutions, hospitals, airports, amongst as many others. The study of the air quality in internal environments (IAQ) is very important for monitoring people’s health effects and their environmental comfort in these locations. One essential parameter to analyze this measure is to evaluate the concentration of dispersed particulates in the air, specially focusing on those thinner particles (below the diameter of 2,5 μm), they can pose serious risks for human being because they can remain in the lungs, penetrate through the pores of our skin, amongst other harmful effects on human’s health. In this work the air quality inside the public library Profª Josina Vasques Ferrari and at Unesp public state library was evaluated, both located in Itapeva, as well as a third one, inside the Communitarian Library of the Federal University in Carlos (UFSCar) from march to may in 2012. In those environments it was analyzed if the concentration of particulates pose any real treat to the users. The equipment used for particle sampling in real time was DataRam 4 (Model DR 4000). The results given for those concentrations of particulates in both internal and external environments revealed figures within the safe standard established by the WHO (World Health Organization), from 25 to μg/m³, the only exception occurred on the fifth floor of the UFSCar library, where the average for concentration stayed at 25,30 of μg/m³

Musculoskeletal disorders in upper limbs in dental students: exposure level to risk factors

Aim: This study assessed the risk factors of undergraduate students to develop musculoskeletal disorders (MSD) in the upper limbs, regarding gender, type of dental clinical procedure, mouth region treated, and the four-handed dentistry practice. Methods: Dental students enrolled in the 8th semester in the Araraquara School of Dentistry, UNESP, Brazil, were photographed while practicing 283 dental procedures. The Rapid Upper Limb Assessment (RULA) method was used to evaluate the working postures of each student. The photographs were evaluated and a final risk score was attributed to each analyzed procedure. The prevalence of risk factors of developing MSD was estimated by point and by 95% confidence interval. The association between the risk factor of developing disorders and variables of interest were assessed by the chi-square test with a significance level of 5%. Results: The risk factors of developing MSD were high, regarding most dental procedures performed by the undergraduate students (score 5: 7.07%, CI95%: 4.08- 10.06%; score 6: 62.54%, CI95%: 56.90-68.18%). There was no significant association between the RULA final score and gender (p=0.559), and type of dental procedure (p=0.205), and mouth regions by arch (p=0.110) or hemi-arch (p=0.560), and the use of four-handed dentistry (p=0.366). Conclusions: It can be concluded that gender, type of dental clinical procedure, mouth region treated, and practice of four-handed dentistry did not influence the risk of developing MSD in the upper limbs among the dental students evaluated; however, they are at a high risk of developing such disorders.

Dentistry teachers and the burnout syndrome

The Burnout Syndrome is considered a psychosocial problem to which teachers are routinely exposed. This study was conducted to estimate the prevalence of burnout in Dentistry teachers and its relation to relevant socio-demographic variables. The participants were 70 teachers from the undergraduate Dentistry Course, Faculty of Dentistry of Araraquara – UNESP. Oldenburg Burnout Inventory (OLBI) was used. The prevalence of burnout was estimated. In order to compare performed. Mean age of participants was 46.0 ± 6.1 and teaching experience was 19.6±7.6 years. The prevalence of burnout was 17.1%. Low mean scores for Exhaustion (2.11±0.61) and Disengagement (1.73±0.50) were observed. There reported taking medication due to work (p=0.008) and for those who have thought about quit teaching (p=0.001).

Investigation on the s of guava (Psidium guajava L.) infusions on germination, root tips and meristematic cells of Latuca sativa

Guava (Psidium guajava L.) is a plant often employed in popular medicine. Recently several studies have alerted about the toxicity of substances present in medicinal plants, which can pose risks to the human health. In this sense, the present work aimed to investigate the phytotoxic, cytotoxic and genotoxic action of three guava varieties - Paluma, Pedro Sato and Roxa (purple) - on the plant test system Lactuca sativa L. Thus, macro- and microscopic evaluations were carried out for five infusion concentrations (2.5, 5.0, 10.0, 20.0 and 40.0 g.L-1) prepared from each variety. Distilled water was used as negative control. Chromatographic and spectroscopic analysis by HPLC-PAD indicated that the chemical composition of the infusion of Roxa is different than that of the infusions of the varieties Paluma and Pedro Sato. It was observed that seed germination and root growth in L. sativa exposed to infusions decreased with increasing infusion concentration, regardless of the tested cultivar. For the mitotic index, no statistical differences were observed. On the other hand, a significant increase in the frequency of cell cycle alterations was verified, especially for the highest concentrations tested. The cytogenotoxic was significant. Therefore, guava should not be used indiscriminately in popular medicine.
