Avaliação da relação entre qualidade de sono e uma intervenção com jogos para o desempenho de crianças e adolescentes

The sleep is an active brain process that allows the efficient realization of daily tasks. The changes on sleep patterns may influence the different cognitive processes performance. Many recent studies show the possibility of cognitive performance improvement, through the cognitive training with the use of computer games. The question is if these interventions may be influenced by the sleep quality. Thus, we evaluated the sleep quality effect about the efficacy of an intervention with computers games based on the working memory and attention for a cognitive performance training of elementary school students. The sample was constituted by 42 students with average age of 10,43 years old (SD=1,23), with 22 male participants and 20 female participants. We used to evaluate the sleep with the parents a sleep questionnaire, a sleep diary and the Sleep Behavior Questionnaire. In regard to intervention, the subjectives were distributed in an experimental and in a control group, both with 21 participants. In the first group occurred the intervention that consisted in the working memory and attention training with two cognitive tasks (Safari e Brain Workshop) during 30 daily minutes, for a 6 weeks period. In an equal period, the students from the control group should reproduce an artwork using drawing software. To evaluate the cognitive performance we applied before and after the intervention period the Wechsler Intelligence Scale for Children (WISC-III). The results showed that in both the groups the performance of the intelligence, working memory, attention and visuospatial skills was below of the mean. The cognitive processes evaluated after of intervention in the experimental group had a performance significantly higher in the Perceptual Reasoning Index (t = -6,24; p < 0,01) and in the Full Scale IQ (t = -5,09; p < 0,01) and Performance IQ (t = -6,52; p < 0,01), suggesting a improvement on the visuospatial skills, attention, working memory and processing speed. On the control group, the performance was significantly higher in the Coding subtest (t = -5,38; p< 0,01) and in the Perceptual Reasoning Index (t = -3,66; p = 0,01), suggesting a improvement on the visuospatial skills and attention. The mean obtained with the Sleep Behavior Questionnaire was 53,76 (SD=14,96) for an experimental group and 61,19 (SD=12,82) for a control group, indicating tendency for a bad sleep quality in that last one. Not only during the first days, but also in the last fifteen days of the intervention we verified in the two groups an adequate time to sleep, duration and regularity, in the weekdays and on the weekends. We didn t find significant differences between the two groups in none of the sleep variables. We verified statistically meaningful improvement on the performance of the experimental group with the intervention in the two games. We didn t verify significant correlations between the games performance index and in the sleep variables of the experimental group individuals. We verified significant correlations among the performance on the Brain Workshop and the Cubes subtest, the Perceptual Reasoning Index and the Scale Performance IQ, suggesting that the significant improvement of the visuospatial skills and of the attention was correlated with the performance in the Brain Workshop. Although the absence of correlations with the performance in the Safari, possibly it also has relieved in the improvement of the cognitive performance. The findings support the hypothesis that the computer games might be a satisfactory tool for the improvement of the performance in visuospatial skills and attention. This can be resulted of the insertion of visuospatial stimulations in the task, for example, graphical elements with thematic for children that increase the interest. The IQ below mean the individuals might have influenced the improvement absence on the cognitive processes like the working memory with games. Moreover, it wasn t verified a relation between the sleep quality and the intervention efficacy. It might have been influenced by the n of the sample. Future studies must focalize in the improvement of the effect of the interventions with games

Efeitos do turno fixo sobre a saúde mental em operadores de petróleo :um estudo de caso em dois ativos produção da Petrobrás

Un conjunto de cambios viene siendo implantado en la Petrobrás procurando que sus unidades de negocios resulten más modernas y competitivas para atender las necesidades del mercado. Dentro de esta perspectiva, un nuevo régimen de trabajo, denominado turno fijo , ha sido implantado en dos activos de producción de la provincia de Rio Grande do Norte. Tal situación originó varios reclamos de los petroleros y, consecuentemente, el interés del SINDIPETRO-RN en obtener una evaluación más precisa de las consecuencias de los mismos. Este estudio, realizado a partir de la demanda sindical de esos trabajadores, ha tenido como objetivo central analizar los efectos del turno fijo sobre la salud mental de los operadores de producción, actualmente lotados en los referidos activos. El estudio ha sido realizado con 39 operadores que representan el 82,9% de la población objeto de este estudio. La muestra ha sido homogénea en cuanto al género, grado de instrucción, edad y tiempo de servicio en la compañía, lo que ha posibilitado un mayor control de las variables y un estudio comparativo entre los dos activos. Para el desarrollo del estudio, se han aplicado los siguientes instrumentos de colecta de datos: una escala de medida probada y validada (QSG-12), un cuestionario abierto, entrevistas individuales y una ficha socio-demográfica. Las respuestas del cuestionario abierto han sido categorizadas mediante la aplicación de análisis de contenido. Los resultados de ese tratamiento y las respuestas del QSG-12 han sido registradas en la forma de banco de datos del SPSS for Windows (Statical Package for social sciense for Windows) para luego procederse con el desarrolllo de los análisis estadísticos. Los principales resultados encontrados en el estudio han sido que la mitad de los participantes de la muestra han presentado resultados de deteriorización de la autoeficacia más elevado que 1,44 (un una escala de 0 a 3) y, en tensión emocional y depresión, el resultado es más elevado que 1,67; la mayoría se da cuenta del aumento de carga de trabajo, revela acentuado sufrimiento con el distanciamiento de la familia, y 58,8% presenta enfermedades psicosomáticas crónicas. La percepción de los operadores sobre el turno fijo e el análisis de éste, conforme el modelo vitamínico de Warr, conducen a la conclusión de que el turno fijo es uno de los factores que está influyendo negativamente en la salud mental de esos trabajadores

Histórias de vida de mulheres idosas :um estudo sobre o bem-estar subjetivo na velhice

The elderly population growth in Brazil and in the world is an incontestable reality, arising from a significant declining rate in mortality and fertility, resulting from the remarkable improvements in the quality of life of the people. Associated with the introduction of new technologies in the medical area, these issues have been highly contributing for the increase of the population longevity. The numbers of the elderly in Brazil and in the world show female population predominance within the aging segment, a phenomenon known as the feminisation of the old-age . Aging, therefore, is nowadays one of the primary issues and that has been mobilizing the Brazilian s society, since the development raised from this new reality brought with it enormous challenges and complex social implications which are already felt in the daily lives of the societies. My work experience among some age groups has shown that aging is a much differentiated process which has instigated my interest in understanding why aging has to face an overwhelming and painful experience for some people and enriched and full of signification for others. Overviewing, this research aimed to understand the aging development through the analysis of the processes of signification and production of meaning that permeate the aging and the subjective well-being of three aged women participants of the Project Health and Citizenship on Third Age /CEFET-RN, that evidenced attitudes and behaviors concerning the integration and the activity toward the elderly population. The methodological strategy used was History of Life, starting from collecting data based on deep interviews. The analysis of data evidenced that the elderly well-being is a unique and distinct meaningful experience for each person, concerning each story of their lives within differentiated social, cultural, economic context, from this perspective one can demystify the concept of that aging occurs in a homogeneous way for everyone, everywhere and with the same rhythm. The narratives presented in this research showed the human development as being a dialectic, discursive and interactionist process which extends throughout the adult life and continues to the aging life. The guarantee that development and aging are a parallel phenomenon always in interdependence on the preceding phases of live, are corroborated within the studies. This present study confirms that the elderly population can be a phase of growth, personal realization and continued development, without disrespecting the heterogeneous and the subjectivity of the person who ages. Notifying those healthy and well-succeeded aging experiences, this issue has the intention to contribute to demystify the concept of aging as a social problem, illness needed to be treated, and the stereotypy of the elderly being dependent and unproductive

Impacto do trabalho em profissionais de Saúde Mental de serviços de saúde do município de Mossoró-RN, 2012

The Psychiatric Reform has brought profound changes in assistance to people affected by mental disorders and behavior. In this context, mental health workers have played decisive roles of great impact, acting driving the process. Objective: To evaluate the impact felt by working professionals, because of the daily work with people who have psychiatric disorders. Methodology: This is a search field, a quantitative approach, sectional, descriptive and applied. Data collection occurred through the Assessment Scale Impact of Working in Mental Health Services (IMPACT-BR) applied to mental health researchers city Mossoró - RN. Results: Participants in this study 87 professionals, mostly female married, which took charge of higher education, working on a single service, working in the area for more than six years, aged between 25 and 64 years. There were a low effect of overloading the professionals surveyed. Discussion: Our results corroborate findings in other surveys conducted previously, not identifying large impact load at work among professionals of mental health teams studied. Subscales studied the highest score was observed in measuring the impact of work on team functioning. It was observed that the greater age and duration of action, reduced the emotional impact at work, suggesting that the experience enhances safety in decisions made and the possibility of greater control over the demands of work. Final Thoughts: The work presented showed that the interactive relationships between professionals and users are not the causes of greatest impact in the workplace, although it revealed overload in relation to specific aspects such as: fear of being assaulted by a patient and the feeling of physical exhaustion the end of the workday. Further investigations should be conducted on this topic in order to contribute to the implementation of psychiatric reform proposed by advances both in terms of assistance to individuals and the quality of life in the work of the professionals involved

The data from the closed questions were treated using the Statistical Package for the Social Sciences (SPSS). The open questions were transcribed and then analyzed the light of theoretical work on the subject. The research reveals that social workers are subject to conditions and labor relations precarious illness causing health problems because some of these professionals, among them are: stress, allergies and skin conditions or, Read / WMSD among other diseases. Thus, we understand the need for debates about the relationship work (the) social worker and worker health before the contradictions of capital also present in public health services

Usos e qualidade da água em região semi-árida do nordeste brasileiro: percepção ambiental de professores e alunos

Density and biomass of bacterioplankton in parts of the Marechal Dutra reservoir were studied in periods of dry and rainy season. The averages of the total bacterial densities oscillated in the order of 107 organisms/ mL of sample. The cocci cells were numerically predominant, influencing considerably the total abundance of the bacterioplankton. The total bacterial biomass, was considered raised and varied from 2.431,82 to 2.739,01 μgC.L-1, in function of the high values of biovolume of the filaments forms, and showed no marked spacial fluctuation. These high values of density and biomass alert for the necessity of a frequent monitoring of aquatic ecosystems of semi-arid region, where the quality of the water is affected by the occurrence of extensive dry periods, influencing considerably the quality of life of its population

A mineração artesanal e de pequena escala em pegmatitos e cerâmica no município de Parelhas, região do Seridó/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Seridó, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

História oral de vida de pessoas com úlcera venosa nos serviços de atenção primária à saúde

The Chronic Venous insufficiency is characterized as a set of physical changes including how most serious complication of venous ulcers, characterized by irregular and progressive loss of continuity of the skin. The occurrence of venous ulcers in people with chronic venous insufficiency generates dependence on them with health services, with long-term treatments that cause limitations and high-impact changes, affecting their quality of life, affecting the physical, psychological, social, cultural and spiritual as an important public health problem. This study aimed to describe the experience of having a venous ulcer, in the scenario of primary health care services to Health, which includes Primary Care Units and Family Health Strategy in the city of Natal / RN, based on the life histories of users. This is a qualitative study, exploratory and descriptive, with the Oral History of Life as a methodological framework. From the ponto zero was the recruitment of participants who formed the network, totaling six employees, of both sexes and aged between 57 and 79 years. After approval by the Research Ethics Committee - UFRN under the Protocol 653 788/2014 and CAAE 30408014.0.0000.5537 was held data collection, between the months of July and August, through interviews, using identification and characterization of the instrument employees and open questions. Interviews were recorded, transcribed, transcriadas and returned to employees for a conference. The narratives were subjected to Content thematic analysis technique, according to Bardin, allowing the construction of three themes that encompass categories, namely: Axis I - Perspectives on the changes: the impact wound in social relations (changes with ulcer venous, venous ulcer and social and family relationships); Axis II - Brands in body and soul: the story of being hurt (conceptions of the body injured; therapeutic itinerary in primary care services); and Axis III - Reconstruction of being hurt: coping mechanisms (redefinition of the wounded body, resilience to chronic wound). The impact of having a chronic venous ulcer generates impact of physical, psychological and social order. As aspects related to changes after the appearance of venous ulcers, survey participants reported the presence of pain, physical limitations, psychological distress, social and emotional isolation, incapacity, aesthetic discomfort and dependency on health services; the family was the aspect thatshowed no significant change after the occurrence of wound for most participants, an ally in the therapeutic process as a support network. The redefinition of the body and the wound are the main coping mechanism of chronic condition. The services in the Primary Care Network play a fundamental role in the rehabilitation of patients with venous ulcers, although there are difficulties in accessing appropriate treatment and need for expanded services, with permanent professional training of health teams and providing the resources managers to strengthen the comprehensive care of people with venous ulcers in Health Primary Care.

Desempenho físico em idosos com diferenciados perfis epidemiológicos: análise do estudo IMIAS International Mobility in Aging Study sob a perspectiva do curso da vida e de biomarcadores da inflamação e do estresse

O crescimento demográfico de idosos é um fenômeno mundial e exerce influência sobre o desenvolvimento e funcionamento das sociedades. Fatores sociais, econômicos, ambientais, biológicos e culturais influenciam o processo de envelhecimento, que pode vir acompanhado de contínua perda na capacidade de adaptação do indivíduo ao meio ambiente, de maior vulnerabilidade ao estresse, limitações funcionais e diminuição da qualidade de vida do indivíduo. Todavia, ao longo do curso da vida, o indivíduo vivencia múltiplas exposições adversas à saúde, e o declínio da mobilidade surge como um dos primeiros sinais do envelhecimento, repercutindo na saúde física e mental do indivíduo. Para contribuir com o conhecimento sobre os desfechos relacionados ao envelhecimento e mobilidade, o estudo IMIAS investiga idosos em quatro países com diferentes perfis epidemiológicos. O presente estudo abordou os possíveis fatores associados ao declínio físico em idosos de distintas sociedades, sobre a perspectiva epidemiológica do curso da vida e dos biomarcadores da inflamação e do estresse. Objetivos: 1) Analisar as relações entre as adversidades sociais e econômicas, vivenciadas durante a infância, a fase adulta e a velhice, com o baixo desempenho físico em populações idosas, de diferentes contextos sociais, econômicos e culturais. 2) Verificar a associação entre os níveis elevados da proteína c-reativa (PCR) com o desempenho físico em idosos de diferentes populações. 3) Avaliar se a desregulação nos níveis de cortisol diurno exerce influência sobre o desempenho físico em idosos com distintos perfis epidemiológicos. Métodos: Foram utilizados dados da linha de base do IMIAS – Estudo Internacional de Mobilidade no Envelhecimento, composto por 1.995 indivíduos entre 65 e 74 anos de idade, residentes em comunidades de quatro países (Albânia, Brasil, Canadá, Colômbia). O desempenho físico foi avaliado através do Short Physical Performance Battery (SPPB) e da força de preensão manual. As adversidades durante o curso da vida foram estimadas a partir de eventos e exposições sociais, econômicas e culturais ocorridas durante a infância, fase adulta e velhice. Para avaliar o percurso biológico e suas associações com a mobilidade, a proteína c-reativa e o cortisol foram considerados como biomarcadores da inflamação e do estresse, respectivamente. No sentido de responder as questões de investigações, foram conduzidas análises de estatística descritiva, bivariada e multivariada, mediante técnicas de distribuição de frequências, teste qui-quadrado, odds ratio e regressões logística, linear e multinível. Resultados: O desempenho físico foi menor nos participantes que vivem na Colômbia, Brasil e Albânia do que nos que vivem no Canadá, mesmo quando ajustados por idade, sexo e adversidades durante o curso da vida. O baixo nível de desempenho físico (SPPB < 8) foi associado a ter sofrido adversidade social e econômica na infância, ter tido ocupação semiqualificada na fase adulta, morar sozinho e possuir renda insuficiente na velhice. A PCR esteve associada com a baixa força de preensão manual e com o SPPB<8. Entretanto, a associação entre a PCR e a força de preensão manual não se manteve quando ajustada por fatores socioeconômicos e hábitos de saúde. As associações negativas entre SPPB e PCR permaneceram significativas mesmo após ajustes por idade, sexo, escolaridade, local de pesquisa e condições de saúde. O baixo desempenho físico (SPPB ≤ 8) foi associado com uma significativa diminuição nos níveis de cortisol ao acordar, em comparação com os níveis de cortisol de idosos com bom desempenho físico (SPPB > 8), mesmo após modelos controlados por local de estudo, sexo, depressão, hábitos de saúde, uso de psicotrópicos e índice de massa corporal. Conclusões: Os resultados evidenciaram associação entre a inflamação, o estresse e as desigualdades sociais e econômicas na infância, sobre o desempenho físico de idosos com diferenciados perfis epidemiológicos. Enfatizamos que a promoção do envelhecimento saudável requer considerar políticas e práticas que favoreçam o bem-estar econômico e social para crianças, adultos e idosos.

Efeitos de um programa de treino cognitivo e das técnicas de higiene do sono para as funções executivas e para a qualidade de sono em idosos saudáveis

The aging process causes changes in the elderly’s sleep/awake standard impairing their cognitive abilities, particularly executive functioning, which already suffers loss by aging. The literature suggests that executive function and preserved sleep quality are key to maintaining good quality of life and independence of older people, requiring interventions to minimize the impact of losses incurred by the aging process. This study evaluated the effect of a cognitive training program and sleep hygiene techniques for executive functions and sleep quality in healthy older people. The participants were 41 healthy older adults, of both sexes, who were randomly divided into four groups: control group [GC], cognitive training group [GTC], sleep hygiene group [GHS] and training group + hygiene [GTH]. The research was developed in three stages: 1st - initial assessment of cognition and sleep; 2nd - specific intervention to each group; 3rd - post-intervention revaluation. The results showed that GTC had significant improvements in cognitive tasks flexibility, planning, verbal fluency and some aspects of episodic memory, besides gains in sleep quality and decrease on daytime hypersomnolence. The GHS improved sleep quality and daytime sleepiness as well and had significant improvements in insights capacity, planning, attention and in all evaluated aspects of episodic memory. The GTH had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. The CG showed significant worsening in excessive daytime sleepiness in capacity planning. Thus, we conclude that cognitive training interventions and sleep hygiene strategies are useful in improving cognitive performance and quality of healthy elderly sleep.

Prevalência, fatores associados e efeitos da violência doméstica na mobilidade em idosos: evidências do estudo imias (international mobility in aging study) sob a perspectiva epidemiológica do curso da vida

A capacidade de mover-se com independência e segurança é fundamental para a execução das atividades de vida diária e manutenção da qualidade de vida do indivíduo. Diversos fatores, dentre eles o envelhecimento podem contribuir para seu declínio. Estudos têm demonstrado associação entre experiências de violência doméstica (VD) e diversos problemas de saúde física e mental. Até o momento, não há estudos que tenham avaliado a associação entre experiências de VD no curso de vida e limitações de mobilidade na senescência. OBJETIVOS: estimar a prevalência da VD (física e psicológica) em idosos, e avaliar o impacto da VD no curso de vida na limitação de mobilidade. MATERIAIS E MÉTODO: Estudo observacional analítico a partir da primeira coleta de dados do estudo longitudinal International Mobility in Aging Study (IMIAS). Idosos (n = 1995) de ambos os sexos entre 65 e 74 anos de cinco localidades distintas (Kingston e Saint-Hyacinthe, Canadá; Tirana, Albânia; Maniazales, Colômbia; e Natal, Brasil) participaram do estudo. Dados sobre variáveis sociodemográficas, econômicas, condições de saúde e experiências de VD (física e psicológica) durante o curso de vida foram coletados. A limitação de mobilidade na senescência foi avaliada pelo Short Physical Performance Battery (SPPB) e pela dificuldade de andar 400 metros e/ou subir um lance de escadas. As prevalências foram avaliadas mediante frequências absolutas e relativas das exposições à VD, limitação de mobilidade e co-variáveis. Diferenças de gênero, bem como entre cidades foram analisadas utilizando o teste de qui-quadrado. Associação entre exposição à VD e limitação de mobilidade foi avaliada utilizando a regressão logística binária multivariada, ajustando pelas co-variáveis. Análise de mediação foram utilizadas, para avaliar possíveis caminhos entre a exposição à VD no curso de vida e a limitação de mobilidade. RESULTADOS: A violência física foi rara, com valores entre 0,63 e 0,85%. Relatos de violência psicológica variaram entre 3,2% e 23,5% (homens) e de 9% para 26% (mulheres). Mulheres experimentaram mais violência do que os homens em Saint-Hyacinthe (homens: 3,2% vs mulheres: 14%, p <0,001), Tirana (homens: 4,3% vs mulheres: 10,3%, p = 0,017), em Manizales (homens: 8,3 % vs mulheres: 18,3%, p = 0,004) e Natal (homens: 11,1% vs mulheres: 26%, p = 0,002). Em geral, o baixo suporte social pelo parceiro foi associado com a VD. Estar trabalhando foi associado a vitimização entre os homens, enquanto o oposto foi verdade para as mulheres. Arranjos de vida Multi-familiares e baixo suporte pelos parceiros, filhos e família foram associados com a VD. Baixo suporte social foi da maior importância para as mulheres do que os homens. A VD física foi associada tanto com o SPPB < 8 (OR 1,623 95%IC 1,161-2,269) como com a dificuldade para andar 400 metros e/ou subir um lance de escadas (OR 1,394 95%IC 1,063-1,829). A limitação de mobilidade decorrente da violência física no curso de vida pelo parceiro íntimo foi mediada pelas condições crônicas (efeito 25,56% 95%IC 0,036-0,277) e depressão (efeito 33,05% 95%IC 0,087-0,333). No caso da violência física por outros familiares, a limitação de mobilidade foi mediada pelas condições crônicas (efeito 20,85% 95%IC 0,022-0,202), não adesão à prática de atividades físicas (efeito 34,14% 95%IC 0,076-0,351) e depressão (efeito 44,40% 95%IC 0,144-0,315). CONCLUSÕES: A violência doméstica no curso de vida é uma realidade, que pode acarretar consequências que favorecem a limitação de mobilidade em idosos. São necessárias políticas públicas que combatam efetivamente a violência doméstica, garantindo um envelhecimento mais digno e independente funcionalmente.

Layout, conforto e satisfação dos usuários em escritórios: uma avaliação pós-ocupação no edifício da sede administrativa do INPE-CRN

This research aimed to identify the link between the layout of workspaces in offices and the design strategies for environmental comfort. Strategies surveyed were focused on the thermal, visual and luminic comfort. In this research, visual comfort is related to issues of visual integration within and between the interior and exterior of the building. This is a case study conducted at the administrative headquarters of Centro Regional Nordeste do Instituto de Pesquisas Espaciais (INPE-CRN), located in Natal/RN. The methodological strategy used was the Post-Occupancy Evaluation, which combined the survey data on the building (layout of workspaces, bioclimatic strategies adopted in the design, use of these strategies) with some techniques aimed at acquiring qualitative information related to users. The workspace layout is primordial to satisfaction and productivity of workers. Issues such as concentration, communication, privacy, personal identity, density and space efficiency, barriers (access, visual and even ventilation and lighting), among others, are associated with the layout. The environmental comfort is one of the essential elements to maintaining life quality in workplace. Moreover, it is an important factor in user`s perception of the space in which he or she are inserted. Both layout and environmental comfort issues should be collected and analyzed in the establishment phase of the programming step. That way, it is possible to get adequate answers to these questions in subsequent project phases. It was found that changes in the program that occurred over time, especially concerning persons (number and characteristics), resulted in changes in layout, generating high density and inflexible environments. It turns difficult to adjust the furniture to the occupants` requirement, including comfort needs. However, the presence of strategies for environmental quality provides comfort to spaces, ensuring that, even in situations not considered optimal, users perceive the environment in a positive way. It was found that the relationship between environmental comfort and layout takes the following forms: in changing the perception of comfort, depending on the layout of the arrangements; adjustments in layout, due to needs for comfort; and the elevation of user satisfaction and environmental quality due to the presence of strategies comfort even in situations of inadequate layout

Avaliação do potencial genotóxico e citotóxico associado a queima artesanal da castanha de caju no Município de João Câmara

The Brazil is the third largest producer of cashew nuts in the world. Despite the social and economic importance of the cashew nut, its production is still carried out artisanally. One of the main problems encountered in the cashew production chain are the conditions under which the roasting of the nut occurs to obtain the kernel from the shell. In the present study was conducted a biomonitoring of the genotoxic and cytotoxicity effects associated with the elements from the cashew nut roasting in João Câmara - RN, semi-arid region of Brazil. To assess the genotoxic was used the bioassay of micronucleus (MN) in Tradescantia pallida. In addition, it was performed a comparative between the Tradescantia pallida and KU-20 and other biomarkers of DNA damage, such as the nucleoplasmic bridges (NBP) and nuclear fragments (NF) were quantified. The levels of particulate matter (PM1.0, PM2.5, PM10) and black carbon (BC) were also measured and the inorganic chemical composition of the PM2.5 collected was determined using X-ray fluorescence spectrometry analysis and the assessment of the cytotoxicity by MTT assay and exclusion method by trypan blue. . For this purpose, were chosen: the Amarelão community where the roasting occurs and the Santa Luzia farm an area without influence of this process. The mean value of PM2.5 (Jan 2124.2 μg/m3; May 1022.2 μg/m3; Sep 1291.9 μg/m3) and BC (Jan 363.6 μg/m3; May 70.0 μg/m3; Sep 69.4 μg/m3) as well as the concentration of the elements Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br and Pb obtained at Amarelão was significantly higher than at Santa Luzia farm. The genotoxicity tests with T. pallida indicated a significant increase in the number of MN, NBP and NF and it was found a negative correlation between the frequency of these biomarkers and the rainfall. The concentrations of 200 μg/mL and 400 μg/mL of PM2.5 were cytotoxic to MRC-5 cells. All together, the results indicated genotoxicity and citotoxicity for the community of Amarelão, and the high rates of PM2.5 considered a potential contributor to this effect, mainly by the high presence of transition metals, especially Fe, Ni, Cu, Cr and Zn, these elements have the potential to cause DNA damage. Other nuclear alterations, such as the NPBs and NFs may be used as effective biomarkers of DNA damage in tetrads of Tradescantia pallida. The results of this study enabled the identification of a serious occupational problem. Accordingly, preventative measures and better practices should be adopted to improve both the activity and the quality of life of the population. These measures are of fundamental importance for the sustainable development of this activity.
