No. of bitstreams: 1 elderstroppa.pdf: 1164894 bytes, checksum: 6cabc43843531bd1b24e6a0c8fe31abe (MD5) Previous issue date: 2012-08-13 / O objetivo primeiro deste trabalho é identificar as barreiras e propor melhorias no processo de apoio, formação e qualificação dos gestores escolares da Superintendência Regional de Ensino de Ubá – MG - (SRE/Ubá), com a proposta de criação de um Núcleo de aprendizagem para apoio e formação de diretores escolares em seu âmbito. A metodologia utilizada foi baseada na experiência de trabalho cotidiano do autor com os gestores das escolas estaduais vinculadas à SRE/Ubá, por meio da observação indireta, da análise documental e uma pesquisa construída em dois momentos. Primeiramente aplicou-se um questionário de caráter censitário aos diretores de escola em exercício na SRE/Ubá, no 1º semestre do ano de 2012 e após uma série de questionários semi estruturados com gestores escolares e gestores da SRE/Ubá que serviu para completar os dados apurados na aplicação do questionário. Os resultados obtidos nesta pesquisa revelam que os diretores de escola estadual desta regional de ensino mineira, não possuem preparação gerencial no momento em que assumem suas funções de direção, que a formação gerencial que detém é obtida por cursos oferecidos pela SRE/Ubá e é desenvolvida juntamente com a prática cotidiana do trabalho. Detectou-se ainda, que existe uma fragmentação no atendimento técnico oferecido aos gestores escolares por parte da SRE/Ubá e que esta fragmentação em muitas oportunidades não está contribuindo com as atividades dos gestores, pois não existe um setor responsável pela coordenação deste atendimento. / The first goal of this work of this work is to identify barriers and propose improvements in the process of training and qualification of directors of Superintendência Regional de Ensino de Ubá – (SRE/Ubá), with the proposed creation of a core of support for learning and training of school principals. The methodology used was based on the experience of daily work of the author with the managers of the schools linked to the SRE/Ubá, through indirect observation and documentary research analysis built in two moments, a censitary character questionnaire, applied to school directors on exercise in SRE/Ubá 1st semester of 2012 and after a series of interviews with school managers and managers of SRE/Ubá that served to complement the data collected in the application of questionnaire. The results obtained in this survey show that the directors of State School of Minas Gerais , regional lack managerial preparation at the time they take their duties of managerial direction the knowledge that they possess is provided by courses offered by SRE/Ubá and is developed together with the everyday practice of work. , that was detected to have a fragmentation in the technical support offered to school directors by the SRE/Ubá and that this fragmentation into many opportunities is not contributing to the activities of directors, since there is not a sector responsible for coordination of care.

Master of Science / Mercury is the most mysterious planet in the inner Solar System, suggested by observations from the MESSENGER mission. These observations shine a light on potential processes occurring within Mercury as it evolved over time. Scientific instruments aboard MESSENGER indicate that Mercury has a very thin surface layer of broken rocks, a thin crustal layer covered by lavas erupted from a melt formed in a relatively thin, FeO poor mantle, and a large metal rich core made from Fe and some quantity of a light element. These conditions are different than those seen on Earth: a thick crust covered by a layer of varied thickness made up of loose unconsolidated rocks and dust, a large mantle with more FeO, and a smaller core to planet ratio. To understand how these non-Earth like conditions affect how the planet's interior changes with time, a modified evolution model was created to track the changes in heat and chemistry within Mercury. This model accounts for complications like a dynamic core density that changes with a growing inner core, the formation method of the inner core, and the FeO poor mantle composition. Using this model offers illumination on the conditions Mercury experienced after it formed. This model is limited, but results suggest that Mercury's mantle began at an initial mantle temperature of 1600 K, and a mantle reference viscosity of 1021–1022 Pa s, indicating the mantle was less likely to flow easily. Model results also suggest the core contained some sulfur from 0.05–8.9 wt.% S, derived from the MESSENGER data. BepiColombo, a new Mercury mission, will provide some perspectives on the interior of Mercury, leading to more detailed information about conditions present after planetary formation and the effect of non-Earth like conditions on a planet's interior as it cools.
