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).

Administration and documentation of nursing care in the nursing career
NOVÁKOVÁ, Kateřina
Administration and documentation are inseparable and obligatory parts of nurse's everyday work. Documentation in healthcare serves to communication of necessary patient information. Medical documentation is kept by physicians. Nursing documentation is conducted in parallel with medical documentation. Nursing documentation records facts of the nursing care provided to a particular patient. Duly kept nursing documentation is a quality indicator of qualified nurse's work. It has to comply with applicable legislation and reflect the latest research results. Documentation has to be brief, clear, concise and factual. It should definitely not be extensive, time consuming, complicated and it should not contain useless information and duplicities. Nurses should not be overloaded by document keeping and should not spend more time on it than with patients. The aims of the thesis: Aim 1: To map the approach to documentation among nurses at selected hospital departments. Aim 2: To map how nurses perceive document keeping in terms of time, how much time they really spend on documentation within their working hours. Aim 3: To analyse nursing documentation at selected hospital departments. Research questions: Research question 1: Do nurses feel overloaded by nursing documentation keeping? Research question 2: How much time do nurses have to spend on documentation within their working hours? Research question 3: Is the time spent on documentation used effectively? Research question 4: Would nurses welcome changes in nursing documentation? Applied methods: The research part of the thesis was based on qualitative research method applied at selected departments of a regional type hospital.The research results from the interviews, document analysis and working hours scanning will be provided to the examined hospital management. They may help the hospital management with better insight into their documentation and lead to improvement of the document keeping in general and particularly ease the work of nurses as they are overloaded anyway.

Isolation and Characterization of Protoplasts and their Utilization for Model Membrane
Nováková, Kateřina ; Navrátil, Tomáš ; Šestáková, Ivana ; Langmaier, Jan ; Heyrovský, Michael ; Zámečníková, B. ; Vodičková, H.
Protoplasts are prepared form plant cells by removing their cell walls, which are usually destroyed mechanically or by enzymes. Protoplasts exhibit the spherical shape after removing of their cell walls. They can be isolated from a range of plant tissues: leaves, stems, roots, anthers, and even pollen. Plasmatic membranes surrounding protoplasts can be used as a source of model membranes. Therefore, some parts of plasmatic membranes or subcellular organelle membranes, which contain specific transport systems, can be isolated and integrated to model phospholipid membranes. State of such model membranes can be characterized by electrochemical impedance spectrometry (EIS) and the transported species can be determined with the use of voltammetric methods.
