Analysing Photographs Sociologically: Photography as a Source of Insight into Social Structure and Social Change
Chládková, Barbora ; Skovajsa, Marek (advisor) ; Sládek, Jan (referee)
The bachelor thesis analyzes a set of photographs taken during the normalization period (1969-1989) in Czechoslovakia using visual fact analysis, semiotic analysis, and sociological structuralist analysis. Firstly, this thesis investigates classical theories of photography with the objective of comprehending the complexities of the photographic medium and identifying key factors to be considered during the analysis of photographs. Furthermore, it explores the use of photography within the field of sociology, with a focus on the techniques employed to interpret and analyze photographic materials. The analysis provides insights into the social structure and characteristics of the normalization period in Czechoslovak society, such as the militarization of society, the prevalence of communist propaganda, and the emphasis placed on labor as one of the pillars of the regime. The analysis also sheds light on everyday life during the period, including recreational practices, unhealthy habits, and family dynamics. Moreover, the thesis emphasizes the significance of using photographs as a complementary tool to other sociological methods in research. Keywords photography, sociology of photography, visual sociology, social structure, normalization (ČSSR)

Voltammetric Determination of 5-Nitrobenzimidazole Using Non-Traditional Electrode Materials
Chládková, Barbora ; Vyskočil, Vlastimil (advisor) ; Zima, Jiří (referee)
5 Abstract This Diploma Thesis is targeted on the determination of 5-nitrobenzimidazole (5-NBIA) using following techniques: DC voltammetry (DCV) and differential pulse voltammetry (DPV). As working electrodes, a silver amalgam paste electrode (AgA-PE), which was constructed for this determination in the form of a new prototype, a bismuth film electrode (BiFE), at which the optimum conditions for the deposition of the bismuth film at a suitable substrate (glassy carbon electrode and gold electrode were tested for this purpose) were initially optimized, and a glassy carbon electrode (GCE) were used. The optimum conditions for the voltammetric determination of 5-NBIA at the AgA-PE (in a medium of Britton-Robinson buffer (BR-buffer) of pH 7.0 for both DCV and DPV), at the BiFE with gold substrate (BR-buffer of pH 9.0 for both DCV and DPV; the film was deposited "ex situ" in a stirred plating solution (1000 mg L-1 Bi(III) solution in 0.1 mol L-1 acetate buffer of pH 4.5) for 300 s), and at the GCE (BR-buffer of pH 5,0 for both DCV and DPV). Under these conditions, calibration dependences were measured in the concentration ranges of 0.1 - 100 µmol L-1 (pro DCV a DPV na AgA-PE) and 1 - 100 µmol L-1 (pro DCV a DPV na BiFE a GCE), and the limits of quantification (LQs) were calculated for particular methods: LQ ≈...

The Position of TOKOZ Company in the European Market of Locks
Chládková, Barbora ; Müller, Štěpán (advisor) ; Valoušková, Michaela (referee)
The aim of this thesis is to evaluate the current position of company TOKOZ in the german and british market and summarise, which of both markets is more suitable for strenghtening the company's position in it. For comparison of the perspective of both markets were used PEST and SWOT analysis, description of the evolution of the company's current export activities in western Europe and characteristics of the market of safety products (locks and hinges) in analysed terirories. After the comparison of all the aspects was decided that more perspective market is the british market.

Voltammetric Determination of 5-Nitrobenzimidazole at a Silver Amalgam Paste Electrode
Chládková, Barbora ; Vyskočil, Vlastimil (advisor) ; Zima, Jiří (referee)
This bachelor's thesis concerns the determination of 5-nitrobenzimidazole (5-NBIA) by the methods DC voltammetry (DCV) and differential pulse voltammetry (DPV). A silver amalgam paste electrode (AgA-PE), which was prepared for this determination in the laboratory, was used as a working electrode. The optimum conditions for voltammetric determination of 5-NBIA were found and under these conditions, concentration dependences were measured and the limits of quantification (LQ) were calculated for each method. The media of BR-buffer pH 7.0 and pH 5.0 were chosen as optimum for DCV determination of 5-NBIA at AgA-PE and DPV determination of 5-NBIA at AgA-PE, respectively. For both DCV and DPV, the linear concentration dependences were obtained in concentration ranges of 5-NBIA from 2 × 10-7 mol/l to 1 × 10-4 mol/l. The attained LQ were found to be 6 × 10-7 mol/l (for DCV at AgA-PE) and 2 × 10-7 mol/l (for DPV at AgA-PE).
