Os laboratórios que trabalham com desenvolvimento tecnológico convivem com o desafio de que as novas tecnologias apontam, cada vez mais, para a especialização. Desta forma, cada atividade desempenhada possui um conjunto de conhecimentos que se articulam, tornando o trabalho altamente complexo, de tal forma que aquele trabalhador configura-se em um especialista naquele setor. O objetivo deste artigo foi analisar as características curriculares e percepções dos egressos do curso de Especialização Técnica em Biotecnologia da Saúde que teve inicio no Instituto de Tecnologias em Imunobiológicos (Bio-Manguinhos)/Fiocruz, no ano de 2004, e que, posteriormente, passou a ser ministrado pela Escola Politécnica de Saúde Joaquim Venâncio. A relevância deste estudo está no fato de que os seus resultados poderão contribuir para a reformulação e aprimoramento do currículo do curso investigado, além de fundamentar estudos curriculares por outras escolas técnicas. Foi realizada uma pesquisa descritiva-documental, com abordagem qualitativa, e teve como sujeitos os coordenadores do curso e os alunos formados nas turmas de 2004 a 2008. Foram utilizados como instrumento de coleta, questionários e entrevistas. A análise das características curriculares e das percepções dos egressos do curso de Especialização Técnica em Biotecnologia da Saúde apontaram a importância de se manter este curso. No entanto, um dos desafios seria a necessidade de se adequar às limitações de formação básica dos profissionais técnicos que trabalham nessa área e que precisam ter o conhecimento teórico para embasar as práticas que já realizam rotineiramente.
FORMAÇÃO DE PROFESSORES DE CIÊNCIAS E MATEMÁTICA NO CONTEXTO DAS TECNOLOGIAS DIGITAIS: O PROINFO EM POÇOS DE CALDAS
Authors: Lisboa Patrícia 
Published: September 2017

Este artigo é resultado da pesquisa de dissertação de mestrado sobre formação tecnológica de professores que lecionam numa rede pública municipal. O contexto do estudo foi um curso de formação continuada em tecnologias educacionais proposta pelo Proinfo. Tendo em vista o objetivo que era avaliar os resultados ou efeitos do curso para a formação continuada docente, executamos e observamos o curso; concomitantemente, aplicamos questionários pré e pós-curso. Após análise dos dados, constatamos que os professores faziam pouco uso dos computadores com finalidades pedagógicas e que após a formação houveram poucas modificações em suas práticas. Nesse sentido, aponta-se que a formação sozinha não instrumentaliza completamente o professor para uso das TICs na educação.
Uma Contribuição do Ensino de Ciências para a discussão e a prevenção do HPV no contexto do Programa de Educação de Jovens e Adultos

Published: September 2017

Este artigo apresenta o relato de experiência de educação para saúde desenvolvida com alunos do Programa de Educação de Jovens e Adultos (PEJA) da cidade do Rio de Janeiro que integravam uma turma do 9º ano. Em um grupo de faixa etária diversa e heterogêneo, foi observada a falta de conhecimento sobre o Papilomavirus humano (HPV) durante as aulas de Ciências. Neste contexto foi desenvolvido um projeto, vinculado à rotina da sala de aula, com o objetivo de trabalhar a prevenção da transmissão e da aquisição do HPV por meio de relações sexuais. Destaca-se que a gravidade da infeção pelo HPV reside em sua relação com o desenvolvimento do câncer de colo de útero e o câncer de pênis. O projeto foi intitulado “Uma proposta para discussão: o HPV”. Com isso, almejou-se inserir e trocar conhecimentos sobre o vírus propiciando a sua prevenção. Como pilar utilizou-se a metodologia de Paulo Freire e sua proposta dialogal que favorece a reflexão e a conscientização. Em resposta observou-se alunos discutindo sobre o vírus e refletindo sobre o próprio comportamento sexual e atitudes anteriormente assumidas. O fato culminou com a construção de um caderno de resumos sobre o HPV pelos educandos. Os resultados apontam ainda a importância de aulas interativas e dinâmicas com maior participação do aluno no processo de ensino-aprendizagem como fator contribuidor para a prevenção de doenças e a promoção de saúde com jovens e adultos.

ABSTRAKSistem Counter Production Monitoring (CPM) diimplementasikan untuk menghitung secara otomotis kecepatan mesin, kecepatan produksi, dan jumlah produksi.Sistem ini digunakan pada mesin pemintal benang di industri tekstil untuk mengetahui efisiensi kerja mesin dan hasil produksi benang.Sistem terdiri dari perangkat keras dan lunak berbasis mikrokontroler dan personal komputer (PC) untuk mengukur putaran mesin guna menghitung ketiga besaran hasil produksi. Inductive proximity sensor dan encoder gear dipasang dengan jarak 1 mm pada shaft mesin yang berputar untuk mendeteksi jumlah putaran mesin berdasarkan jumlah pulsa yang dideteksi oleh sensor selama durasi tertentu. Mikrokontroller menghitung tiga besaran produksi dan menampilkan hasil pada display LCD melalui pengaturan 3 buah tombol serta mengirimkan ke PC melalui komunikasi serial untuk ditampilkan. Hasil pengujian selama 3 hari menunjukkan terjadi perbedaan antara sistem CPM dan perhitungan manual (Tachometer) yaitu antara 0.35-0.4 HANK.Perbedaan terjadi karena pada perhitungan manual, mesin diasumsikan selalu berjalan. Padahal pada kenyataannya terjadi proses dopping (penggantian cone benang). Dapat disimpulkan bahwa sistem CPM telah dapat digunakan untuk mengetahui efisiensi kerja mesin dan hasil produksi secara otomatis.Kata kunci: counter production monitoring, encoder gear, Inductive Proximity Sensor, mikrokontroler, personal komputer.

This system was employed on a spinning machine in a textile industry to know machine efficiency and a number of thread productions. The system consists of some microcontroller-based hardware and software modules to detect machine rotation. Inductive proximity sensor and encoder gear were installed with a rotary machine shaft in 1 mm distance. A number of machine rotation was calculated from the number of pulses that detected by sensor for a certain time duration. Microcontroller calculated three production values and displayed on LCD by controlling three different push buttons. Subsequently, the data transferred to PC via serial communication to be displayed on PC. From three days testing, the system showed a different result of 0.35-0.4 HANK total production between CPM system and manual procedure using Tachometer. The different was due to the machine was assumed still working during dopping (change thread cone) process in the manual procedure. As a conclusion, CPM system can be used to know the machine efficiency and the number of thread production automatically.Keywords: counter production monitoring, encoder gear, Inductive Proximity Sensor, microcontroller, personal computer.
