Dining traits of the elderly in tourism
Nováková, Kateřina ; Mlejnková, Lena (advisor) ; Netková, Jarmila (referee)
The main goal of this diploma thesis is to perform an analysis on how dining needs of mature travellers are accomodated by chosen service providers. Based on the analysis the thesis evaluates the ability of the providers to individually tailor their services to mature guests. Subsequently, certain proposals for improvement are formulated. The analysis is performed on the four providers: an international cruise line specialised in elderly travels and three hotels situated in Prague. The thesis is composed of four parts. The first two parts serve as an introduction to the segment of mature travellers - their needs are identified and explained, also their travelling motivations are revealed. Last two parts are devoted to analysis of the services, summarization of the results and improvement proposals.

Tax systems of the selected developing countries
Nováková, Kateřina ; Láchová, Lenka (advisor) ; Dugová, Alena (referee)
The aim of the thesis is to become familiar with the business environment in Guatemala and Costa Rica, especially from a tax perspective. The thesis is primarily focused on the information necessary for an investor who decides about where he put his money with the biggest cash benefit. The first part is focused on the theoretical aspects that deal with developing countries and political and economic conditions resulting from their position in the world economy. The constituent part is the theory of FDI and related development in selected countries. The goal of the second part is comparison of individual components of the tax systems in selected countries. Primarily it is focused on investor decision-making and at the same time is devoted to the description of tax policy with an effort to attract foreign investment. The whole thesis is finished by a case study, the purpose of which is an illustration of conditions in both countries in a particular investment. Based on the study, it is concluded which country is favorable for investors from a tax perspective.

Finanční gramotnost žáků víceletého gymnázia
Nováková, Kateřina ; Votava, Libor (advisor)
The diploma thesis "Financial literacy of pupils at grammar school" deals with the attitudes of students to the issue of financial literacy and the level of their knowledge. It focuses on individual components of financial literacy and key factors which influence and shape the students' knowledge and attitudes. Comparing available literature sources the definition of financial literacy is discussed in the theoretical part. The theoretical part also includes the way financial education is regulated in the Czech Republic. The practical part using a descriptive statistical analysis presents results received from the questionnaire distributed among pupils of the grammar school. Based on the results four hypotheses were set and their validity is tested. The evaluation and discussion parts are incorporated in the work.

Lab-made Sensors Based on Boron-doped Diamond for Determination of Herbicide Linuron
Štěpánková, M. ; Šelešovská, R. ; Janíková, L. ; Vojs, M. ; Marton, M. ; Behúl, M. ; Nováková, Kateřina ; Chýlková, J.
Voltammetric behaviour of substituted urea herbicide linuron (LIN) was investigated using two types of boron-doped diamond electrodes (BDDE): commercial BDDE and lab-made sensors based on boron-doped diamond (LM-BDDE). Various methods like cyclic voltammetry (CV), direct current voltammetry (DCV) and differential pulse voltammetry (DPV) were examined. It was found that LIN provides one oxidation peak using all of the tested working electrodes and the highest current response was recorded in the acidic media. Thus, Britton-Robinson (B-R) buffer of pH 2 was used as a supporting electrolyte. Parameters of DPV were optimized and the low limits of detection (LOD) were reached 1.41×10−7 M for commercial boron-doped diamond electrode and 8.81×10−9 M, respectively, which represents the lowest LOD obtained for lab-made boron-doped diamond electrodes.

Influence of Cadmium on its Metabolism and Changes of Content of Nutritionally Important Compounds in Spring Barley
Paznocht, L. ; Vodičková, H. ; Phuong, L. M. ; Nováková, Kateřina ; Zámečníková, B. ; Kotíková, Z. ; Miholová, D. ; Navrátil, Tomáš
Very important agriculture products are cereals, which significantly contributes to securing of human nutrient needs. Cadmium is a toxic heavy metal, which is readily taken up and accumulated by plants in spite of its harmful effects. This metal cause a stress for the plants and results in many morphological, anatomical, physiological and biochemical changes. The effect of cadmium on the plant metabolism and changes in the content of nutritionally important compounds (protein and some metals – Fe, Zn, Cu, Mn content) was investigated. Results shown, that cadmium was effectively retained in the roots and content of studied compounds was influenced by present of cadmium in nutrient medium. In all the parts of cadmium-treated seedlings decrease in the iron content and increase in the zinc content (except of the first leaves) and decrease in the manganese content was found. The copper content in the root tissue increased by 112.1 %, on the other hand a significant decrease (by 44.4 % and 40.9 % respectively) in the first and the second leaves was observed. In the experimental varieties with cadmium in the concentration of 10-5 mol L-1, the content of soluble proteins was determined statistically higher in the root and basal parts than in the controlled varieties.

Use of Silver Solid Amalgam Electrode for Determination of Acaricide Amitraz
Nováková, Kateřina ; Harvila, M. ; Navrátil, Tomáš ; Zima, J.
The electrochemical behavior of amitraz was studied at polished (p-AgSAE) and mercury meniscus modified (m-AgSAE) silver solid amalgam electrodes. The reaction mechanism was investigated using direct current voltammetry (DCV) and elimination voltammetry with linear scan (EVLS). The optimum conditions for differential pulse adsorption stripping voltammetry (DPAdSV) determination of amitraz were found in Britton-Robinson (BR) buffer mixed with ethanol in a volume ration of 1:4. DPAdSV with optimized parameters was applied for determination of amitraz in analyzed solutions. The limits of detection were calculated as 8.9 nmol L-1 (tacc = 20 s) for m-AgSAE and 0.168 mol L-1 (tacc = 20 s) for p-AgSAE. The proposed method was successfully applied for determination of this compound in real sample solutions.

Information on Several Interesting Case Reports of Liquid Mercury Intoxication
Navrátil, Tomáš ; Vlčková, Š. ; Mrázová, K. ; Nováková, Kateřina ; Zakharov, S. ; Honsová, Š. ; Pelclová, D.
This contribution reports on several mercury non-professional intoxications. It can be summarized that it is very important to differentiate among forms of mercury which can (acute or chronic) endanger human health. Contrarily to the wide spread fears, liquid mercury represents low danger for men and for environment. Solid amalgams are probably the less toxic forms of mercury compounds. On the other hand, widely spread daily consumer goods can be very dangerous and toxic (saving balls, fluorescent tubes, etc.). Moreover, these goods are not marked as “toxic mercury containing”. The article discusses the instruction for removing mercury from our environment. Most of the reported data are based on database of the Czech Toxicological Information Centre (TIC) (from the years 1995 – 2015).
