Item Os riscos tecnológicos na sociedade de risco: possíveis danos da poluição eletromagnética à saúde humana(Universidade Federal de Goiás, 2023-12-12) Alves, Mônica Oliveira; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Leite, Marcos Esdras; Lima, Cláudia Valéria de; Chaveiro, Eguimar Felício; Santos, Nicali Bleyer Ferreira dosThe technological advancement experienced from the mid-20th century onwards has brought about a series of transformations in modern society. This applies both in terms of the benefits and conveniences offered by new technologies and the potential health risks, such as electromagnetic pollution, generated by products and infrastructures designed to meet the needs of urban populations. Globally, there is a growing public and regulatory concern about the impacts on human health due to exposure to risks generated by high-voltage power transmission lines in urban areas. In this context, there is a noticeable need to investigate this issue in Brazil, where cities, both medium and large, have experienced rapid and unplanned population growth, leading many people to reside near these infrastructures. Therefore, the main objective of this study is to analyze the issues related to the health risks generated by exposure to electromagnetic radiation from high-voltage power transmission lines in the urban space of Montes Claros/MG. The chosen location for the investigation was the city of Montes Claros, located in the north of Minas Gerais, where various population groups were observed inhabiting areas considered exposed to electromagnetic pollution generated by the mentioned sources. The methodological procedures involved literature and documentary research, mapping of areas exposed to risk, and surveys with the general population, particularly those residing in one of the risk areas in the city of Montes Claros. The results obtained demonstrated that there are various population groups residing in risk areas in the city, often in locations where occupation occurred irregularly, such as in the servitude zones of high-voltage lines, accentuating social exclusion and socio-spatial segregation in Montes Claros. It was also noted that the population has limited awareness of the risks they are exposed to, hindering the search for strategies and actions by civil society to mitigate the problem. Given the identified issues, it is suggested that further studies be conducted, and precautionary measures be implemented regarding these risks. This should involve the participation of public and private entities, the scientific community, and the general public, promoting a democratic risk management approach in Montes Claros and other urban centers in Brazil.Item Chuvas e inundações em Goiânia: dinâmica atmosférica e áreas de risco(Universidade Federal de Goiás, 2015-03-27) Rego, Thalyta Lopes; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Zavattini, João Afonso; Zancopé, Marcio Henrique de CamposDeforestation and waterproofing of various spaces are common procedures in the urbanization process. These processes, with the fact that the valley bottoms are naturally amenable to flooding, can lead to various disorders for the local population. In Goiania, these events are increasingly accompanied by the local media, and the Civil Defense. From this context, this research performs the mapping of floods in the urban area of Goiânia, between 2000 and 2013 and seeks to identify the atmospheric system that causes these events. Thus, we analyzed and specialized reports published in a newspaper whit the highest circulation in the city and Civil Defense servisse reports. Data from the Meteorological Station of Goiânia were organized in rhythmic analysis charts to understand the atmospheric systems active during flood events. The results show that the floods in Goiania occur nearest the central region of the city, except for two points, which are located in the northern region. It was found that in investigated points the houses are very close to the river and urbanization around these points is quite intense. Another point to be highlighted is the decrease of vegetation in the city during the study period. It was noticed that the most active atmospheric system in the flook occurrences in Goiania are the Repercussion of Polar Mass, the Polar Front and the Equatorial Continental Mass with squall lines. We presented some measures to prevent the flooding, based on surveyed bibliographies.Item Clima e arenização em Gilbués-Piauí: dinâmica das precipitações e a vulnerabilidade da paisagem aos eventos pluviais intensos(Universidade Federal de Goiás, 2014-03-28) Silva, Ivamauro Ailton de Sousa; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Zancopé, Márcio Henrique de Campos; Sales, Marta Celina LinharesEn este estudio, se investigó el proceso de degradación ambiental en Gilbués adoptar el concepto de "arenization" para caracterizar la erosión del suelo. El documento analiza la dinámica de precipitación y su influencia en el proceso de arenization, haciendo hincapié además en las interfaces con otros elementos del paisaje. Para su desarrollo, después de una extensa revisión de la literatura, había una compilación de mapas temáticos, recopilación, organización y análisis de los datos de precipitación de la estación hidroclimática de Superintendencia de Desarrollo del Nordeste, para el período 1963-1999. Las visitas técnicas permitieron el análisis del paisaje, registros fotográficos y entrevistas con investigadores y lugareños. Los gráficos de precipitación y de tramas-síntesis que permitieron la identificación de los períodos con patrón seco, normal y húmedo y el tiempo de desarrollo de los riesgos climáticos, que indican los meses en los que fueron diseñados el paisaje se vuelve más vulnerable a la erosión del agua. La dinámica de precipitación en Gilbués probaron de la siguiente: a) precipitación con alta variabilidad espacial y temporal, con distribución irregular a lo largo del año, tanto a escala anual, mensual y diária; b) precipitación concentrada entre diciembre y febrero; c) ocurrencia de fuertes lluvias, la precipitación alcanza 144 mm / día. El riesgo cronograma indica que diciembre, enero y febrero son los meses de mayor vulnerabilidad en el paisaje, así como los períodos de lluvias más intensas. Otra consideración importante es el período de la llamada transición climática (inicio de las lluvias y tardio la sequía), cuando el paisaje es susceptible y las primeras lluvias tienen intensidades altas y moderadas. La investigación llevó a las siguientes conclusiones: a) el aumento de las precipitaciones acelera arenization; b) el proceso de arenization deriva de la acción del agua de lluvia en zonas con suelo expuesto, está estrechamente asociado a la escorrentía del agua de los cursos de agua, que se producen en las laderas circundantes colinas / montañas que se someten a la regresión. Las principales limitaciones para la ocurrencia de la arenization son: estructura litopedológica, los aspectos geomorfológicos, ecológicos (maleza) e hidrológicos (flujo de drenaje fluvial) y, por último, los episodios de lluvias torrenciales. A través del análisis de las condiciones geo-ambientales y de la historia de la ocupación de la región, se puede afirmar que el proceso se estabiliza y su origen es natural, aunque en algunos períodos se ha intensificado (ocasionalmente) por antropogênico.Item Poluição e qualidade do ar, modelagem ambiental da dispersão dos poluentes de fonte fixa(Universidade Federal de Goiás, 2018-03-28) Valenzuela Saavedra, Gabriel Cristóbal; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Souza, Lucas Barbosa e; Santos, Nicali Bleyer Ferreira dosEl presente estudio tiene como finalidad encontrar un camino metodológico para modelar la dispersión de contaminantes atmosféricos provenientes de fuentes de emisión fija, a través de materiales baratos y simples. El camino insto de la revisión teórica de los principales conceptos de la contaminación atmosférica y la calidad del aire, así conocer cuales factores determinan áreas vulnerables a la contaminación atmosférica. Se usó una fuente de emisión fija de una industria alimentaria para mostrar un análisis de lo que sería un estudio de impacto ambiental de las emisiones producto de la operación normal de la fábrica para el año 2012, sin la intención de evaluar, si no, para mostrar cómo se aplica el modelo en un caso práctico. De esta forma, colocar en disposición una metodología que pueda ser usada en estudios que ayuden a la toma de decisión para la planificación en la introducción de nuevas fuentes de emisión o la alteración de las antiguas. Como resultado, se consiguen imágenes donde es fácilmente reconocible el área de susceptibilidad de las emisiones provenientes de la fuente fija, las que son interpretadas para aclarar que podría pasar frente a los diversos escenarios posibles.Item O regime pluviométrico, o ritmo e as excepcionalidades das precipitações em Jataí – GO(Universidade Federal de Goiás, 2017-03-16) Vasques, Hérika Silva; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Oliveira, Ivanilton José de; Santos, Nicali Bleyer Ferreira dosConsidering climate as the yearly sequence of weather patterns, it may be viewed as ultimate result of the interaction between geographic variables, these being responsible for the atmospheric dynamics. Such acknowledgment contributes significantly to urban and rural planning, as it indicates, among other elements, precipitation, temperature variation, wind speed and direction, solar radiation, and relative humidity, which when associated to the surface, respond for various climatic phenomena. In this research, rainfall is highlighted as the true indicator of weather patterns in tropical savanna climates, such the case of the Goiás state. In this sense, the research had as main objective to analyze the rainfall regime and comprehend the sucession rate of atmospheric states of exceptional nature in the Jataí region, thus contributing to the climatic profiling of the researched area. This work was undertaken by mold of the Geographic Climatology, from quantitative (quartile deviation, central tendency distributions, Schroeder's pluviograms) and qualitative (rhythmic analysis) techniques. The study presents as conclusion the region's climatic regime and the atmospheric systems' participation table. The rainfall in Jataí is related, mainly, to frontal passings and action of an unstable Tropical-atlantic and Equatorial-continental air mass.Item Tempo meteorológico e ritmo climático: efeitos sobre a morbidade e a mortalidade causadas por doenças cardiovasculares no município de Goiânia – GO(Universidade Federal de Goiás, 2021-08-05) Vasques, Hérika Silva; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Chaveiro, Eguimar Felício; Nascimento, Diego Tarley Ferreira; Murara, Pedro Germano dos Santos; Pascoalino, Aline; Barros, Juliana RamalhoConsidering that the climate and weather interact in the Earth system and, consequently, with living things such as human beings, even the slightest seasonal variations and weather changes can trigger or significantly aggravate the health state and well-being of individuals. In this research, atmospheric elements such as maximum and minimum temperatures, low humidity and atmospheric pressure variation, have a prominent position. Therefore, this thesis aims to investigate the relation between thermal variation and morbidity-mortality by cardiovascular diseases on the city of Goiânia, Goiás, from 1999 to 2017. For this, the Brazilian Geographic Climatology and the Geography of Health served as theoretical framework. The methodology was supported mainly by rhythmic analysis and the Pearson correlation coefficient, with the first one allowing for a systemic approach. As for the major results, it was possible to observe that cardiovascular diseases in Goiânia are prevalent during winter and in advanced age groups. The statistical analysis allowed to infer that atmospheric pressure and low relative humidity of the air answer significantly for the aggravation of those diseases, since they were directly related to both intensive care admittance and fatal outcomes. Lastly, the dynamic evaluation, undertaken by the rhythmic analysis, evidenced that the southern and eastern currents can destabilize the human organism – during the passage of these systems on the studied area, there was an increase in the number of deaths.
