Rozvíjení trojdimenzionálního - prostorového - myšlení, které je důležité pro poznávání světa a pochopení osobní identity v něm, je důvodem k častějšímu prosazování prostorové tvorby ve výuce na základních školách. Tato identifikace by měla probíhat na základě tvůrčích aktivit podmíněných poznávací hodnotou celistvosti lidského zážitku. Ohniskem pohledu by mělo být vzájemné doplňování prostorového a plošného vyjadřování, přičemž diferenciace tkví ve vymezení pólů trojdimenzionální a dvojdimenzionální formace. Stává se ale, že při rozlišování obou útvarů ve výuce dochází k omylům, které hovoří o nedostatečném pochopení či úplné desinterpretaci problému způsobu vyjadřování. Zároveň se ukazuje, že preference plošné tvorby a distance od prostorové tvorby ve výuce je velmi častá. Příčinou se zdá být technologická náročnost prostorové tvorby (v přímé úměrnosti s časovou), která souvisí s výtvarnou průpravou pedagogů. Hlavním zaměřením mého odborného zájmu i obsahu mé disertační práce je prostorová plastická tvorba, její kvalitativní a kvantitativní zastoupení ve výuce výtvarné výchovy na primárním stupni základní školy. Domnívám se, že souvztažnost kvality a kvantity prostorové tvorby souvisí s pregraduální přípravou studentů - učitelů a s jejich oborovým zaměřením. Powered by TCPDF (www.tcpdf.org)

The diploma work is focused on the ceramic tool materials and its effective use. The introductory part of the work contains the detail characteristic of the ceramic tool materials from the point of view of their dividing, physic-mechanical propertis, production methods and marking. The main part of the work is focused to judging of the ceramic portion at the production assortment of the top World producers of tool materials and to evaluation of cutting ability of the particular materials of these producers. The detail analysis of recommended cutting conditions, which is aimed to an effective use of the ceramic materials, had been worked up for this purpose. The technical economic analysis confirms, that the present effective aplications of ceramic are limited only for specific cases of machining cast irons, steels and alloys.

Thesis dealing with cutting ceramics and its efficient use. Introduction describes the general characteristics of the cutting of ceramics, its history and development and production of various kinds. This section describes the mechanical and physical properties with potential application in machining. The se-cond part is an overview of cutting-frame in the range of selected world leaders. Ano-ther section focuses on general assessment of the power of cutting tools and other ma-terials comparison. The fourth part, is comparing the working conditions of producers and tools intended for cutting.

This diploma thesis consists of two main parts {--} a practical and a theoretical one. The aim of the practical part was to design and create seven ceramic wall clocks and to plant clockworks with hands into them. The theoretical part deals with time measurement in history, it follows the development of time measuring devices from the antiquity to the present. It also describes the techniques used by creating the set of clocks and ideal and motivational sources which have influenced the processing of this topic.

I created the cycle of 5 plastic reliefs with the motifs of space effects in my project. As the first model I chose the moon in fog which it is said about that it has a ghostly power. As the second theme I chose the Earth like the symbol of all living. The third motif is the planet Saturn by which I was impressed with its rings. The fourth theme I called Neptune which is the windiest planet. The last motif is Pluto and it`s the smallest planet. I usted the color designed for low {--} temperature fixation for 170 ° C for thein decoration. As the motivation source were instrumental the creative works of František Peterka in my theoretic work. I verified the using of low {--} temperature stove paint in scholastic practice as compared with the ceramic enamel.

The thesis deals with the study of the influences of selected groups of chemical agents on the stability of PTC ceramics based on BaTiO3. The experimental part includes elaboration of methodology for determination of these influences, their evaluation, including the hypotheses for their description, and evaluation of groups of chemical agents having these influences.

Master’s thesis are concerned with the cutting ceramic materials and its ef-fective usage. The first part of the thesis is focused on the general properties of the cutting ceramics, its history, development, production and description of the various types. This part includes as well a description of the mechanic-physical properties and the potential of the usage for machining. The second part of the work solves the general evaluation of the cutting power. The main issue in the next part is the identification of cutting ceramics range and the selection accor-ding to main world producers. The fourth part deals with the assessments and the comparison of the working conditions for different types of the machined ma-terials. The technical economic assessment shows the potentials in the total pro-duction costs reduction.
