Mělnická urbanonymie: Případová studie vývoje názvů ulic na Mělníku v 19. a 20. století / Melnik's urbanonymy: The case study of the development of the names changing of streets in Melnik during the 19th and 20th centuries

Burian, Lukáš January 2020 (has links)
This diploma thesis deals with the dynamic changes of the street terminology system in the town of Melník from the second half of the 19th century to the present. There are cases where it is necessary to study, which are located under the field of historical toponomastics, respecting its parts that have urbanonymy. The works carry out, show and analyze the issue of street names that move in the town of Melník during the period under review. The work is in five places, the first part of which consists of analysis and heuristics, which allows the analysis of documents, especially documents that are focused on documents that are part of the Melnik archive and Archive of Department of Construction and Development of the Municipal Office in Mělník. Remember that you keep in mind the city councils, you write down the city's national committee, letters etc. The second chapter, which is part of the subchapter by period, lists historical developments that have urban and significant changes. The third place is the municipal toponomastic analysis of Melnik street terminology from the point of view of basic onymic functions of urban names and from the point of view of the use of honorification names. The next chapter consists of a name interpretative list of individual street names, in which chronological data...

No. of bitstreams: 1 Keiji Nakamura.pdf: 1405144 bytes, checksum: 8b57bd3e002695a33fe5b4bdbf0840e3 (MD5) Previous issue date: 2008-05-30 / Sociedade de Cultura e Educação do Litoral Sul / The main objective of this work is to investigate the difficulties that appeared along the history for the development of the mathematical content irrational numbers and which are the approaches present in the text books. The subject irrational numbers is considered important in the basic education of Mathematics and it comes for the students, in the text books, as an obstacle to its full understanding. One of the aspects that can justify such situation is the complexity that the subject shows. However, the irrational number can be worked in a historical-epistemological process, by doing a study of how the transformation of scientific object to an object of teaching in a praxeological organization has been processing. That organization is the final result of a mathematical activity that presents two inseparable aspects: the mathematical practice, that consists of tasks and techniques, and the speech based on that practice that is constituted by technologies and theories. Our analyses point that factors exist which interfere in the process of teaching-learning of irrational numbers related with the praxeological organization of that content in the collections of the text books of the 70s, 90s and 2000. The proof of the irrationality with traditional Euclidian approach served as parameter to evaluate the degree of difficulty and to analyze the type of tasks, techniques and the theoretical-technological speech for the demonstration of the irrational number. The organization points that the most difficulty is in the axiomatic system that should satisfy to two conditions: to be solid, it means, the postulates cannot contradict each other for themselves or for their consequences; to be complete and enough, in the sense of having conditions to prove true or false all propositions formulated in the context of the theory in subject. The proof of the irrationality in a modern Dedekind approach analyzed by the type of tasks, techniques and for the theoretical-technological speech enlarges the numeric domain, joining to the rational numbers a new category of irrational numbers that fill out the gaps of the numeric straight line. To build techniques to modify and to enlarge the concept of irrationality of other numbers is an approach that explores numbers in the form a+b√2, with rational a and b, and that contributes to overcome the idea that there are few irrational numbers / O objetivo principal deste trabalho é investigar as dificuldades que surgiram ao longo da história para o desenvolvimento do conteúdo matemático números irracionais e quais a abordagens estão presentes nos livros didáticos. O assunto números irracionais é considerado importante na escolaridade básica de Matemática e apresenta-se para os alunos, nos livros didáticos, como um obstáculo a sua plena compreensão. Um dos aspectos que pode justificar tal situação é a complexidade com que esse assunto se manifesta. No entanto, o número irracional pode ser trabalhado em um processo histórico-epistemológico, fazendo-se um estudo de como se tem processado a transformação de objeto científico a objeto de ensino em uma organização praxeológica. Essa organização é o resultado final de uma atividade matemática que apresenta dois aspectos inseparáveis: a prática matemática, que consta de tarefas e técnicas, e o discurso fundamentado sobre essa prática, que é constituída por tecnologias e teorias. Nossas análises apontam que existem fatores os quais interferem no processo de ensino-aprendizagem de números irracionais relacionados com a organização praxeológica desse conteúdo nas coleções dos livros didáticos dos anos 70, 90 e 2000. A prova da irracionalidade com abordagem tradicional euclidiana serviu de parâmetro para avaliar o grau de dificuldade e analisar o tipo de tarefas, técnicas e o discurso teórico-tecnológico para a demonstração do número irracional. A organização aponta que a maior dificuldade está no sistema axiomático que deve satisfazer a duas condições: ser consistente, quer dizer, os postulados não podem contradizer uns aos outros por si mesmos ou por suas conseqüências; ser completo e suficiente, no sentido de se ter condições para provar verdadeiras ou falsas todas proposições formuladas no contexto da teoria em questão. A prova da irracionalidade em uma abordagem moderna dedekindiana analisada pelo tipo de tarefas, técnicas e pelo discurso teórico-tecnológico amplia o domínio numérico, juntando aos números racionais uma nova categoria de números irracionais que vêm preencher as lacunas da reta numérica. Construir técnicas para modificar e ampliar o conceito de irracionalidade de outros números é uma abordagem que explora números na forma a+b2, com a e b racionais, e que contribui para a superação da idéia de que há poucos números irracionais
