A importância da comunicação não-verbal do professor universitário no exercício de sua atividade profissional / The importance of non-verbal communication for teachers in the exercise of their professional activities

OBJETIVO: verificar a importância da comunicação não-verbal do professor no exercício de sua atividade profissional. MÉTODOS: a presente pesquisa foi realizada no período de março a maio de 2008. A população de estudo foi composta por alunos de dois cursos de graduação (Ciências Biológicas e de Fonoaudiologia). Foram escolhidos, aleatoriamente, alunos de cada turma, independente de sexo ou idade, compondo um total de 63 alunos. RESULTADOS: os dados obtidos mostraram que, independente da sua formação (se fonoaudiólogo ou não), todos consideraram que a comunicação não-verbal do professor é um importante fator na transmissão das mensagens. CONCLUSÃO: a pesquisa mostrou que os entrevistados avaliaram a comunicação não-verbal como importante para a efetividade da interação, podendo interferir no desempenho do docente em sala de aula.

PURPOSE: to check the importance of non-verbal communication for teachers in the exercise of their professional activities. METHODS: this research was conducted during the period from March to May, 2008. The studied population was made up of students from the two under-graduation courses the (Biological sciences and speech therapy). They were chosen randomly, 63 students, regardless of gender or age. RESULTS: data obtained showed that, regardless of their training (whether or not speech therapist), everybody considered that the non-verbal communication of the teacher is an important factor in the transmission of messages. CONCLUSION: the research showed that the investigated students and teachers evaluated the non-verbal communication as important for the effectiveness of interaction and can interfere in the performance of teachers in the classroom.

Susceptibilidad antimicrobiana de Streptococus pneumonia colonizante de nasofaringe en ninos colombianos con neumonia / Antibiotic susceptability of Streptococcus pneumoniae colonizing the nasopharynx of Colombian children with pneumonia

Streptococcus pneumoniae es uno de los principales agentes causales de infección respiratoria aguda (IRA) en niños y su resistencia a antibióticos se ha incrementado en todo el mundo. En este estudio se determinaron los patrones de susceptibilidad a antimicrobianos de S. pneumoniae colonizante de las vías respiratorias altas en 272 niños hospitalizados por neumonía en dos hospitales de Santafé de Bogotá. Se aisló S. pneumoniae en 114 pacientes (42%). Se observó susceptibilidad disminuida a la penicilina en 19 aislamientos (17%), con sensibilidad intermedia en 12 (11%) y franca resistencia en 7 (6%). Solo 1 de los 19 aislamientos resistentes a penicilina mostró también resistencia a la ceftriaxona. Se observó sensibilidad disminuida a la eritromicina en 3 aislamientos (3%), al cloranfenicol en 6 (5%) y al cotrimoxazol (trimetoprima + sulfametoxazol) en 46 (40%). Se encontró multirresistencia en 7 aislamientos (6%). El serotipo con sensibilidad disminuida a la penicilina que se halló con mayor frecuencia fue el 23F (68,4%). Se observó una asociación entre la edad, el uso previo de antibióticos y la colonización con S. pneumoniae con susceptibilidad disminuida a la penicilina o multirresistencia. Este estudio confirma la presencia de resistencia antimicrobiana de S. pneumoniae en Colombia y resalta la importancia del uso racional de los antibióticos y de la implementación de la vigilancia epidemiológica sobre este agente

Streptococcus pneumoniae is one of the principal causal agents of acute respiratory infection (ARI) in children, and its resistance to antibiotics has increased worldwide. This study examined the patterns of susceptibility to antibiotics of S. pneumoniae that had colonized the upper respiratory tract of 272 children hospitalized for pneumonia in two hospitals in Santafé de Bogotá. S. pneumoniae was isolated from 114 patients (42%). Diminished susceptibility to penicillin was noted in 19 isolations (17%), with 12 (11%) showing an intermediate level of sensitivity and 7 (6%) outright resistance. Only 1 of the 19 isolates resistant to penicillin also showed resistance to ceftriaxone. There was diminished sensitivity to erythromycin in 3 isolations (3%), to chloramphenicol in 6 (5%), and to cotrimoxazole (trimethoprim + sulfamethoxazole) in 46 (40%). Resistance to multiple drugs was found in 7 isolations (6%). The most commonly encountered penicillin-resistant serotype was 23F (68.4%). An association was observed among age, previous use of antibiotics, and colonization by S. pneumoniae with reduced penicillin susceptibility or multiple-drug resistance. This study confirmed the presence of antibiotic-resistant S. pneumoniae in Colombia and highlights the importance of the rational use of antibiotics and of the implementation of epidemiologic surveillance for this agent
