Aquecimento e Desaquecimento Vocal em Estudantes de Pedagogia

Introduction: the voice is one of the main features of interaction between teacher and student. As teachers, future teachers are also risk population for the development of dysphonia and may be subject to protective intervention. Purpose: to evaluate the effect of a vocal warm-up and cool-down procedure at Pedagogy students. Method: A quasi-experimental study, pre-posttest without a control group, with fourteen Pedagogy students at a public university, participants of a short course. The analysis was performed by a self-assessment visual analogue scale of 10 cm, considering aspects related to the body and voice. The protocol was implemented in three steps: pre-test, post warm-up and post cool-down, and it was calculated the averages of the variables of discomfort and compared the measurements before and after performing each procedure. It was used the the Wilcoxon signed-rank statiscal test, adopting a significance level of 5%. Results: there was less discomfort with statistical significance after the vocal warm-up (p=0.002) and cool-down (p=0.001), with greater magnitude in both aspects related to voice. Conclusions: The vocal warm-up and cool-down have positive effects on the perception of students and should be taught to future teachers in order to prevent vocal disorders. The vocal cool-down, poorly researched, should not be passed over vocal health practices since its purpose showed obvious improvement in the investigated group.

Análise técnica e econômica da utilização da energia solar e eólica em uma propriedade rural para geração de eletricidade, bombeamento e aquecimento de água

This paper is about a case study of using solar energy and wind energy in a farm. For this purpose were collected from the property, such as water consumption and amount of residents. So, we estimate how many conventional panels or PET bottle panels and boiler needed to supply the farm with warm water. It also calculates the amount of photovoltaic panels and the main accessories for converting solar energy into electrical energy. For the pumping of water using photovoltaic panels is dismissed and dimensioned to be a watermill

Comparando a eficácia da manta térmica com método de aquecimento passivo na prevenção de hipotermia

Hypothermia is a common phenomenon in the perioperative period, and it affects 60 to 90% of patients submitted to anesthetic-surgical procedures. In order to minimize its incidence, warming methods are used. Such methods can be passive, such as orthopedic cotton, sheets and blankets, or active, such as warm-air blankets and thermal mattresses. In this scenario, the present study aimed at comparing two warming methods used in the intraoperative period. Patients submitted to abdominal surgery in the specialties of gynecology and gastric surgery from August to September 2010 were included in the study. After randomization, they were divided into two groups: one using a thermal blanket (group I) and one using orthopedic cotton (group II). At last, 9 patients were included. The variables for each question were considered according to occurrence frequency. Comparison between groups was performed by Student’s t test. With the purpose to analyze whether there was an association, the chi-square test or Fisher’s Exact test was used. Whenever it was applicable for multiple comparisons, Tukey’s test was utilized; p values < 0.05 were considered to be statistically significant for analysis. The sample comprised 6 males and 3 females submitted to gynecological and gastric surgeries. Their mean age was 48 years for group I and 46.2 years for group II. A predominance of general anesthesia was observed. The time of permanence in the operating room ranged from 80 to 360 minutes. With regard to warming parenteral solutions, the procedure was performed on 5 patients, and infusion of warm solution into the abdominal cavity was performed on 50% of the sample. Concerning the warming method used, 5 patients used a thermal blanket. In view of the results presented, it was not possible to conclude which warming method should be used due to sample size

Cálculo do tempo de permanência de um cilindro de laminação em um equipamento de aquecimento por indução durante um processo de têmpera

Induction heating is a process closely linked to the concepts of heat transfer. It also covers electromagnetic induction and effect of film. Many companies use this technology in their processes due to the high accuracy that can be obtained at temperatures induced. However the dominance of this technology is not common among Brazilian industries. This involves complex systems of equation and heat exchange in transient conduction, and convection and radiation losses. With this work we seek the ability to analyze which parameters influence over this process and the order of magnitude of time required for heating a cylindrical part

Mudanças climáticas: o discurso da mídia sobre o aquecimento global

This research is aimed at discussing the ways in which social agents influence global warming, analyzing the discourse of social actors involved in the debate on climate change, since there is a wide divergence in the scientific community about how man is able to modify the climate on a global scale. In fact the debate that permeates the issues beyond the limits of science and enter into a political-economic framework that takes extraordinary proportions. This emphasis can be very unscientific in the fundamental design concepts, or even creating a trivialization of the media. The main way to convey these concepts is to disclose them in the media, but the media has enormous power to transform the concepts and often manipulate the news by creating a common sense goes against the interests of the scientific community. Thus was conducted extensive research in major newspapers and magazines that move in the country. We surveyed the first two papers which were: “Folha de S. Paulo” and “O Estado de S. Paulo”, during the period from January 2000 to December 2008, totaling 3285 units for the newspaper Folha and 2555 for the newspaper Estadão. Subsequently a survey was made of data published in two journals that move at the national level, and these are the magazines VEJA and ÉPOCA for the same period. By performing these steps, it was concluded that several factors involving the media and climate change, such as topic relevance, types of approaches, perspectives of analysis, the staff development, supplies, among other factors of utmost importance for building news. As a result we can say that the media in fulfilling its role of mediator scientific, disclosing only a vision that permeates the scientific debate. The newspaper media, especially newspapers, has an informative and instantaneous. Often this preoccupation...(Complete abstract, click electronic access below)

Aquecimento vocal para o canto erudito: teoria e prática

Vocal warm-ups are essential for the technical training of the singer, for good speech and performance, as well as essential for good vocal health and a long-lasting career. Objective: To analyze the theory and practice of the vocal warm-up in classical singing, from the perspective of different professionals in the voice field including: teachers, speech therapists and singers. Method: descriptive search, quantitative in nature, cross-sectional, with a questionnaire for voice teachers, singers and audiologists. The sample consisted of 165 subjects: 86 voice teachers, 64 speech pathologists, and 15 singers. Results: Teachers of Singing (97.7 %), singers (95.3 %) and students (93.3 %) use the vocal warm-up. Conclusion: From the results we can infer that most of the professionals surveyed point to the importance of the implementation of the vocal warm-up before a performance, and the strategy used by most voice instructors, speech therapists and singers is vocalization, i.e. aesthetic warm-up.

Utilização da percepção subjetiva de esforço para controlar a intensidade do aquecimento realizado através da corrida em crianças

The aim of this study was to verify the use of exertion subjective perception to control warm-up intensity performed by continuous running in children. Twenty-one children (11,4 ± 0,8 years, 45 ± 9,8 kg e 153,6 ± 9,6 cm), performed warm-up by continuous running in randomic order in three conditions with diferent intensities using rate of perceived exertion (RPE). The intensities were chosen according to RPE Borg CR-10 and the arbitrary units used were three (B3), Five (B5) and nine (B9). The heart rate (HR) and mean velocity of the run (VEL) were evaluated to analyse the intensity of the three warm-up conditions. Statistical analysis was done by annova one-way followed by post-hoc tukey test, considering significant level of 5%. There were significant increase in HR (B3= 112 ± 10, B5 = 140 ± 18 e B9 = 176 ± 21 bpm) and VEL (B3 = 4,01 ± 0,5, B5 = 7,09 ± 1,22 e B9 = 10,97 ± 1,70 km/h) between B5 and B9 condition compared to B3. Moreover, in both parameters B9 presented significantly higher results compared to the condition B5. It´s possible to control warm-up intensity performed by continuous running in children using RPE Borg CR-10.
