Bonding of 3D printed PET-G parts
Maxa, Ondřej ; Kupčák, Radim (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis solves the problem of gluing PET-G material, which is used for printing 3D models in 3D printers. The goal is to select and then test the adhesive suitable for bonding the material. The suitability of the recommended adhesives was determined on the basis of standardized tests on experimental blasting equipment. Based on the measurement results, it is suitable to use one-component instant adhesives for gluing PET-G material, the advantage of which is easy handling and quickly achievable handling strength.

Development of socio-economic factors on the development of land use in the selected locality
MAXA, Ondřej
The main goal of this thesis was to evaluate the development of socio-economic factors depending on the development of land use in the village Chvalšiny. This analysis was carried out over the last thirty years, i.e. from 1991-2021. This time was divided into four periods - 1991, 2001, 2011 and 2021. The reason for this division was the availability of data from the Census of Population, Houses and Apartments, which is held every ten years. To determine developmental changes over time, the results of the mentioned Census of Population, Houses and Apartments (socio-economic factors) and archival orthophoto maps (land use) on the ČÚZK geoportal were used, specifically the viewing service WMS - Archival Orthophoto. Individual partial works, connected with the development of final map outputs, took place in the ArcGIS Pro program (a newer version of the ArcMap program). The results of selected socio-economic factors (9) were processed in the form of tables in the Microsoft Excel program. During the practical part, it was found that the municipality of Chvalšiny shows favorable values in the long term in terms of socio-economic indicators, and in the near future it should not face problems that could lead, for example, to the depopulation of the municipality. In terms of land use, there has been a noticeable change when over the years up to 95 % of the original arable land area has been converted to permanent grassland (TTP) and today only 24.6 hectares of arable land can be found in this area. An unambiguous mutual relationship between the development of socio-economic factors and the development of land use, where it would be possible to clearly state that one of the indicators has a clear impact on land use or vice versa, could not be demonstrated in this time period.

Rozvinutost periferních, semiperiferních a střediskových sídel okresu Český Krumlov
MAXA, Ondřej
The main goal of the bachelor thesis was evaluation of human and demographic capital of peripheral and other types of settlements in Český Krumlov district. In the first step, settlement centres with different hierarchy (micro-regional towns, very small towns, townships, central villages and more important villages) were defined based on indicators such as population, services for residents, number of commuters and number of transport connections in working day (bus and train). In the second step, peripheral settlements were bordered in the map based on 30-minute isochron of bus and train connections to micro-regional towns (also ultra-peripheral settlements - behind 60-minute isochron) as well as suburban settlements (based on characteristics of suburbanisation) and semi-peripheral (remaining settlements). In the third step, human and demographic capital in individual remote types of settlements (variably long population development, age structure, education, entrepreneurship rate, housing construction and age of municipal representatives) were evaluated. In monitored district, there are 2 micro-regional towns (Český Krumlov, Kaplice), 3 very small towns (Velešín, Větřní a Vyšší Brod), 3 townships, 10 central villages and 10 more important villages. Approximately 41% of the district area and 19% of the district population belong to peripheral and ultra-peripheral settlements. Surprisingly, semi-peripheral settlements have the most favourable values of human and demographic capital, and even also ultra-peripheral settlements and settlements without joints for some indicators. Peripheral settlements also have relatively favourable values. These findings greatly undermine the conventional notion of the underdevelopment of peripheral territories.

The return of old brands like a phenomenon ostalgia in Czech republic
MAXA, Ondřej
The goal of this thesis is to describe and explain the process of comeback of the Czechoslovakian trademarks and products from the time of socialism. The thesis is divided into the theoretical and the practical part. The beginning of the theoretical part focuses on the genral introduction of the "ostalgia", including the brief description of the process of "ostalgia" in other countraies of the former Eastern Block. Another part of this thesis focuses on the reasons why today´s population of Czech republic tends to these nostalgic memories. What´s the reason of the comeback of trademarks like Kofola, céčka, botas etc. Why do people tend to these old trademarks and if it is somehow connected with people´s wish to get the time and way of living in socialism back. Or if this is just the regular nostalgia or the real "ostalgia"? The practical part of my thesis consists of the questionnaire regarding the "ostalgia", the fact hbow the middle generation remembers their youth in the socialism, how they feel about the comeback of the old trademarks or if there´s some more former trademarks they wish to come back. The questionnaire was also presented to a young generation to be able to compare the different opinions of two generations. The final part of the thesis consists of the analysis of the questionnaire and its results.
