To keep good and non-conflict relationships between doctors and nurses is not an easy task their stressful working environment. Despite the fact that both doctors and nurses have a common goal, and that is to provide the best care of their patients, there are situations leading to conflicts between doctors and nurses. Good relationships between nurses and doctors are a guarantee of a harmonized cooperation in the entire medical team. That is why it is important to avoid conflicts and, if any conflict has already occurred, it is important to use it for the benefit of the whole team. The goal of our work was to define the most frequented conflicts in hospitals from a point of nurse's view in a cooperation with doctors, and what impact these conflicts have on nurses' work. To process the data in the first part of my thesis, the quality method for a research survey was used. The data collection was implemented by interviews. The research sample group was composed of eight nurses working in bed departments of different hospitals. On the grounds of the quality survey I set four hypotheses which I tried to verify in the quantity survey. To collect the data in the quantity part a questionnaire survey was used and the research sample group was also composed of nurses working in bed departments. The data were being collected in the period of March through May. To assess the results 175 questionnaires were used. The hypothesis 1 - The most frequented conflicts between nurses and doctors root in a wrong communication, has been proven on the grounds of our findings. The hypothesis 2 - Conflicts between nurses and doctors result from increasing competences for nurses has been proven, too, as well as the hypothesis 3 - Conflicts between nurses and doctors result from misunderstanding nurses' and doctors' roles. The hypothesis 4 - Conflicts between nurses and doctors have a negative impact on nurses' work was proven, too. The results have also revealed that the second most frequented reasons for conflict situations represent personal qualities of doctors, which was not included in the hypotheses. In the summary of the thesis I incorporated some recommendations how to handle conflict situations effectively. This work should be a foundation for a potential follow- up research not only in this field, but it can also serve management teams in medical institutions. They should take actions to improve the situation to some extent.

[pt] A qualidade das águas dos corpos hídricos nas áreas urbanas é normalmente comprometida em função da grande quantidade de lançamento de esgotos com ou sem tratamento inadequado, trazendo impactos ambientais, econômicos e sociais. Esta pesquisa tem o objetivo de analisar a capacidade de gestão e os arranjos de governança de instituições e agentes públicos responsáveis pelo saneamento do complexo lagunar de Jacarepaguá e a existência de um arcabouço de leis ambientais. A partir da revisão bibliográfica pesquisou-se o histórico da ocupação e do desenvolvimento da infraestrutura urbana da região onde está situado o complexo lagunar. Os boletins da qualidade das águas das lagoas e rios foram levantados do período de 2013 a 2019. Os resultados obtidos são comparados com os resultados de estudos científicos realizados com dados que retroagem ao início dos anos 80. A legislação das matérias de recursos hídricos e saneamento foram pesquisadas com objetivo de identificar as atribuições dos atores envolvidos. Constatou-se que as águas do complexo lagunar apresentam um alto grau de poluição com enorme aporte de esgoto in natura e que as causas são as consequências de irresponsabilidade e omissão dos diversos atores que atuam no planejamento, na fiscalização, na regulação, no controle e na prestação dos serviços de esgotamento sanitário. Somam-se a isso um conflito de competência entre o Estado e o Município, ocupações irregulares e o mau funcionamento de instalações privadas. / [en] The major economy of the city of Rio de Janeiro is tied into its tourism and leisure industry, due to its unique natural beauty of its landscape. The unique combination of mountains meeting the sea has earned it the title given by UNESCO of the First Urban and Cultural Landscape declared World Heritage. This takes into consideration the area s natural and urban monuments of the South zone, in particular, but recognizes the unique relationship between man and nature, and the balance between natural and man-made elements. It considers the environmental and social interaction, which enables its citizens to enjoy various forms of leisure activities associated with the area s unique natural beauty. However, despite this designation, on the west side of the city, there are found other natural beauties, including the coastal lagoons of the Jacarepaguá lagoon system. But here, the environment has been completely neglected by the government. In these lagoons, people cannot fish, sail, or swim. The use of these ecological sites is prohibited due to the contamination of the waters. A natural heritage for all, the waters have become degraded with the presence of raw sewage, which causes the foul smell, disease, and the reduced presence of fauna and flora. Unregulated construction on its banks and on the edges of its tributaries has caused these bodies of water to become filled with garbage, sand, and all sorts of debris, besides the sewage. From its primitive origin until the implementation of the Urbanist Lúcio Costa s plan, the region remained preserved. Corrêa (1933), testified crystal clear water lagoons and flooded green fields where fishing, hunting, and natural resources were abundant. However, even at this early date, he observed the degradation of forests and the hunting of animals out of control, and recorded a lack of regulation by the governing body, the Water and Sewage Inspectorate. He therefore suggested, inspired by the laws of the Office International pour la Protection de la Nature, the creation of a biological reserve for Marapendi lagoon, realized in 1965.
