Resumo: Introduction: The global warming has severe environmental impacts and reach different areas and localities, in particular the least developed countries in the tropical region. In Brazil, the regions that suffer most impacts, with such changes will be the Amazon and Northeast. With the development of modern society, it is observed that individuals are consuming much of their time indoors, so, numerous studies have sought to study environmental comfort conditions to assist in the execution of activities and maximize human performance. One of the many changes that took place is in the learning environment, which is different compared to years ago. Technological resources in the classroom have made this a more versatile environment, allowing students and teachers to interact with other institutions, providing greater flexibility in the use of tools that extend their cognitive abilities. However, these tools can both facilitate communication and versatility of teaching and learning as increase the thermal load in the environment that already suffers direct influence of the external environment. In this sense, important to investigate how it is the variables of thermal comfort affect students' performance in climate-controlled learning environments provided these technologies. Objective: We analyzed the relationship between thermal comfort and performance of students in environments with technological innovations in areas of northeastern Brazil. Materials and Methods: Data were obtained during the experiments in the two institutions classrooms (A and B) of higher education located in Northeast Brazil. The Institution A is a private university in the city of João Pessoa- PB and the institution B is a public university in city of Teresina-PI. A total of 103 students of the engineering course participated, with one session per day, per class, on three consecutive days. The air temperature through the air conditioning was adjusted to 20ºC and 24ºC; the last day and is turned off the device to try to reach the value of 30 ° C. By heat stress meter TGD400 and microclimate station Babuc A, positioned in the center of the room recorded the parameters of the thermal environment. Cognitive abilities were assessed by the five events that make up the BPR-5 instrument, broken down for the three days of the experiment. Subjective and personal variables were evaluated in accordance with ISO7730/2005, through check list (thermal resistance of clothing) and scales of 4 points (Comfort) and 7 points (Sensation and Desire). With the results and data obtained were carried out simulations using the Generalized Linear Models (GLM) to verify the relationship between thermal comfort and performance. Results: At the institution A 42,9% of the first day of collection, where the temperature was in it 21,49ºC, indicated to be feeling slightly warm environment (+1) and 51,9% said that the place was comfortable (1). The PMV index of ISO7730/2005 indicated that the room was cold, with 57% of the vote between -1,5 and -2,5. On the second day, with an average temperature was 23,24ºC, about 58,1% of the students felt the thermally neutral environment (0) and 55,4% rated it as comfortable (1). The PMV index, on the second day, indicated that the room was slightly cold, with 87,8% of the vote between -0,5 and -1,5. On the third day the mean temperature was 27,49ºC and 41,9% of the rated as hot environment (+2) and finally, 35.1% VII of the evaluated local rated as slightly uncomfortable (2). The Middle Foretold vote indicated that the room was slightly hot on the third day, with 60.8% of votes ranging from +0,5 to +1,5. The institution B, on the first day of collection whose average temperature was 20,07ºC, about 50% of students reported feeling that the environment was slightly cold (-1) and 61.5% of students rated the environment as comfortable (1). The PMV index indicated that the environment was cold with 92% of the vote results were between -1,5 and -2,5. On the second day the average temperature was 33,72ºC and 59,3% of students said they felt the warm environment (+2) and 66,7% rated it as uncomfortable (3). Regarding the PMV 100% of the frequency of the votes indicated that the environment was rated as very hot (PMV> +2.5). On the third day with the average temperature 22,95ºC, about 73,3% of the students indicated that the thermal sensation was neutral (0) and the place was rated by 96,2% of the students as comfortable (1). The PMV index showed that 88,5% of the calculated votes of the students indicated that the site was slightly cold (-0,5 <PMV <-1,5). Using Generalized Linear Models, in particular the Ordinal Regression, was observed from the data of the two institutions, the performance is linked to subjective criteria, in particular the thermal sensation and the globe temperature. It was observed that the rise globe temperature in 1 ° C increases the chance of students pass a performance range lower to a higher 34% for situations where the wind chill is indicated as very hot. Final considerations: This study showed that there is a difference between what the standard ISO7730/2005 predicts what is actually reported by students in areas of the Brazilian Northeast, ie situations where the standard indicates discomfort students report being comfortable. It was also observed that subjective variables are important factors for a good cognitive performance of students.

No Brasil, as regiões que mais sofrerão impactos, com tais mudanças, serão a Amazônia e o Nordeste. Com o desenvolvimento da sociedade moderna, observa-se que os indivíduos estão consumindo grande parte do seu tempo em ambientes fechados, e por isso, numerosas pesquisas vêm buscando estudar condições de conforto ambiental que auxiliem na execução das atividades e maximização do desempenho humano. Uma das diversas mudanças que ocorreram, encontra-se no ambiente de ensino, o qual é diferente quando comparado ao de anos atrás. Recursos tecnológicos em sala de aula têm tornado este ambiente mais versátil, permitindo que alunos e professores interajam com outras instituições, conferindo maior flexibilidade na utilização de ferramentas que estendem suas habilidades cognitivas. Nesse sentido, torna-se importante investigar como as variáveis do conforto térmico afetam o desempenho dos alunos em ambientes de ensino climatizados providos destas tecnologias. Objetivo: Analisar a relação entre conforto térmico e o desempenho de estudantes nos ambientes com inovações tecnológicas em áreas do nordeste brasileiro. Materiais e Métodos: Os dados foram obtidos durante a realização dos experimentos nas salas de aula de duas instituições (A e B) de ensino superior localizadas no Nordeste brasileiro. A instituição A é uma universidade privada e encontra-se na cidade de João Pessoa- e a instituição B é uma universidade publica e encontra-se na cidade de Teresina. No total de 103 alunos dos cursos de exatas das duas instituições participaram, sendo uma sessão por dia, por turma, em três dias consecutivos. A temperatura do ar, através do ar condicionado, foi ajustada para 20ºC e 24ºC; no último dia desligou-se o aparelho para tentar se chegar ao valor de 30°C. Através do medidor de estresse térmico TGD400 e estação microclimática Babuc A,posicionados no centro da sala, registraram-se os parâmetros do ambiente térmico. As habilidades cognitivas foram avaliadas pelas cinco provas que compõem o instrumento do BPR-5, decomposto para os três dias de experimento. As variáveis subjetivas e pessoais foram avaliadas de acordo com ISO7730/2005, através de check list (resistência térmica das vestimentas) e escalas de 4 pontos (Conforto) e 7 pontos (Sensação e Desejo). Com os resultados e dados obtidos realizaram-se simulações através dos Modelos Lineares Generalizados (MLG) para se verificar a relação entre conforto térmico e desempenho. Resultados: Na instituição A 42,9% dos alunos no primeiro dia de coleta, onde a temperatura encontrava-se a 21,49ºC, indicaram estar sentindo o ambiente levemente quente (+1) e 51,9% avaliaram que o local estava confortável (1). O índice PMV da ISO7730/2005 indicou que o ambiente estava frio, com 57% dos votos entre -1,5 e -2,5. No segundo dia, cuja temperatura média foi de 23,24ºC, cerca de 58,1% dos alunos sentiram o ambiente termicamente neutro (0) e 55,4% classificaram-no como confortável (1). O índice PMV, no segundo dia, indicou que o ambiente estava levemente frio, com 87,8% dos votos entre -0,5 e -1,5. No terceiro dia a temperatura média foi de 27,49ºC e 41,9% dos alunos classificaram o ambiente como quente (+2) e por fim, 35,1% dos avaliados classificaram o local como levemente desconfortável (2). V O Voto Médio Predito indicou que o ambiente estava levemente quente no terceiro dia, com 60,8% dos votos variando de +0,5 a +1,5. Na instituição B, no primeiro dia de coleta cuja temperatura média foi de 20,07ºC, cerca de 50% dos estudantes indicaram sentir que o ambiente estava levemente frio (-1) e 61,5% dos alunos classificaram o ambiente como confortável (1). O índice PMV indicou que o ambiente estava frio com 92% dos resultados obtidos dos votos estavam entre -1,5 a -2,5. No segundo dia a temperatura média foi de 33,72ºC e 59,3% dos alunos afirmaram que sentiam o ambiente quente (+2) e 66,7% classificaram-no como desconfortável (3). Em relação ao PMV 100% da frequência dos votos indicaram que o ambiente foi classificado como muito quente (PMV> +2,5). No terceiro dia com a temperatura média de 22,95ºC, cerca de 73,3% dos estudantes indicaram que a sensação térmica era neutra (0) e o local foi classificado por 96,2% dos alunos como confortável (1). O índice PMV mostrou que 88,5% dos votos calculados dos alunos, indicaram que o local estava levemente frio (-0,5<PMV<-1,5). Utilizando Modelos Lineares Generalizados, em especial a Regressão Linear Ordinal, observou-se através dos dados das duas instituições, que o desempenho está ligado aos parâmetros subjetivos, em especial a sensação térmica e a temperatura de globo. Foi observado que ao se elevar a temperatura de globo em 1ºC aumenta-se a chance dos estudantes passarem de uma faixa de desempenho inferior para uma superior em 34%, para situações onde a sensação térmica é indicada como muito quente. Considerações finais: Este estudo mostrou que existe uma diferença entre o que a norma ISO7730/2005 prediz com o que realmente é relatado pelos estudantes, de áreas da região do nordeste brasileiro, ou seja, situações em que a norma indica desconforto os estudantes relatam estar confortáveis. Observou-se também que as variáveis subjetivas são fatores importantes para um bom desempenho cognitivo dos estudantes.Universidade Federal da ParaíbaBrasilEngenharia de ProduçãoPrograma de Pós-Graduação em Engenharia de ProduçãoUFPBSilva, Luiz Bueno daTorres, Manoel Geronimo Lino2018-06-06T12:02:25Z2018-07-21T00:02:10Z2018-07-21T00:02:10Z2016-04-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfTORRES, Manoel Geronimo Lino.

One of the many changes that took place is in the learning environment, which is different compared to years ago. Technological resources in the classroom have made this a more versatile environment, allowing students and teachers to interact with other institutions, providing greater flexibility in the use of tools that extend their cognitive abilities. However, these tools can both facilitate communication and versatility of teaching and learning as increase the thermal load in the environment that already suffers direct influence of the external environment. In this sense, important to investigate how it is the variables of thermal comfort affect students' performance in climate-controlled learning environments provided these technologies. Objective: We analyzed the relationship between thermal comfort and performance of students in environments with technological innovations in areas of northeastern Brazil. Materials and Methods: Data were obtained during the experiments in the two institutions classrooms (A and B) of higher education located in Northeast Brazil. The Institution A is a private university in the city of João Pessoa- PB and the institution B is a public university in city of Teresina-PI. A total of 103 students of the engineering course participated, with one session per day, per class, on three consecutive days. The air temperature through the air conditioning was adjusted to 20ºC and 24ºC; the last day and is turned off the device to try to reach the value of 30 ° C. By heat stress meter TGD400 and microclimate station Babuc A, positioned in the center of the room recorded the parameters of the thermal environment. Cognitive abilities were assessed by the five events that make up the BPR-5 instrument, broken down for the three days of the experiment. Subjective and personal variables were evaluated in accordance with ISO7730/2005, through check list (thermal resistance of clothing) and scales of 4 points (Comfort) and 7 points (Sensation and Desire). With the results and data obtained were carried out simulations using the Generalized Linear Models (GLM) to verify the relationship between thermal comfort and performance. Results: At the institution A 42,9% of the first day of collection, where the temperature was in it 21,49ºC, indicated to be feeling slightly warm environment (+1) and 51,9% said that the place was comfortable (1). The PMV index of ISO7730/2005 indicated that the room was cold, with 57% of the vote between -1,5 and -2,5. On the second day, with an average temperature was 23,24ºC, about 58,1% of the students felt the thermally neutral environment (0) and 55,4% rated it as comfortable (1). The PMV index, on the second day, indicated that the room was slightly cold, with 87,8% of the vote between -0,5 and -1,5. On the third day the mean temperature was 27,49ºC and 41,9% of the rated as hot environment (+2) and finally, 35.1% VII of the evaluated local rated as slightly uncomfortable (2). The Middle Foretold vote indicated that the room was slightly hot on the third day, with 60.8% of votes ranging from +0,5 to +1,5. The institution B, on the first day of collection whose average temperature was 20,07ºC, about 50% of students reported feeling that the environment was slightly cold (-1) and 61.5% of students rated the environment as comfortable (1). The PMV index indicated that the environment was cold with 92% of the vote results were between -1,5 and -2,5. On the second day the average temperature was 33,72ºC and 59,3% of students said they felt the warm environment (+2) and 66,7% rated it as uncomfortable (3). Regarding the PMV 100% of the frequency of the votes indicated that the environment was rated as very hot (PMV> +2.5). On the third day with the average temperature 22,95ºC, about 73,3% of the students indicated that the thermal sensation was neutral (0) and the place was rated by 96,2% of the students as comfortable (1). The PMV index showed that 88,5% of the calculated votes of the students indicated that the site was slightly cold (-0,5 <PMV <-1,5). Using Generalized Linear Models, in particular the Ordinal Regression, was observed from the data of the two institutions, the performance is linked to subjective criteria, in particular the thermal sensation and the globe temperature. It was observed that the rise globe temperature in 1 ° C increases the chance of students pass a performance range lower to a higher 34% for situations where the wind chill is indicated as very hot. Final considerations: This study showed that there is a difference between what the standard ISO7730/2005 predicts what is actually reported by students in areas of the Brazilian Northeast, ie situations where the standard indicates discomfort students report being comfortable. It was also observed that subjective variables are important factors for a good cognitive performance of students.
