Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Electrophysiologic Characteristics of Wide QRS Complexes during Pharmacologic Termination of Sustained Supraventricular Tachycardias with Verapamil and Adenosine: Observations from Electrophysiologic Study

Methods: Patients with supraventricular tachycardia, undergoing electrophysiologic study were enrolled. 12 mg of adenosine or 10 mg of verapamil were administered during tachycardia, under continuous monitoring of intaracardiac and surface electrocardiograms. Electrocardiographic features of ventricular ectopy were noted

The Epidemiology of Foot Wounds in Patients with Diabetes: A Description of 600 Consecutive Patients in Turkey

Epidemiological studies describing demographic, clinical, and surgical characteristics of diabetic foot wounds are lacking in Turkey. To further describe the epidemiology of diabetic foot wounds in Turkey, we developed an evaluation form and performed a retrospective cohort study that entailed 600 diabetic patients who were admitted to the hospital for treatment of their foot wound(s). The mean age of the cohort was 62.3 +/- 10.3 (range 23-92) years, and their mean duration of diabetes was 17.4 + 7.4 years. Males accounted for 68.17% of the cohort, and 96.83% of the cohort had type 2 diabetes. Prevalences for lower extremity arterial pulses and peripheral neuropathy, as well as the location, depth, microbiology, and surgical treatment of the pedal wounds are also presented. In conclusion, diabetic foot wounds are common in Turkey, and the morbidity associated with these lesions is generally substantial. Although our investigation aimed primarily at describing risk factors associated with diabetic foot wounds, we believe that the findings of this investigation can be used in the development of prospective cohort studies and randomized controlled trials that focus on foot wounds in diabetic patients in Turkey, and may be useful to investigators in other parts of the world.
