STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

Past and present of education of paediatric nurses and their attitudes towards their own profession
ZMEŠKALOVÁ, Stanislava
This thesis deals with the history and present state of the education of paediatric nurses and their attitudes towards their own profession. The first objective was to find out information regarding the education in the nursing profession in Bohemia, with a focus on child care, and to create an overview of the education in the profession Paediatric Nurse. The second objective was to find out about the attitudes of paediatric nurses towards their profession. Interviewed were sisters who chose the profession after finishing elementary school and underwent qualifying studies as well as nurses who chose the profession after graduating from a secondary school or university education and achieved their education through specialization studies. The last objective was to compare these two groups and to assess whether there are any differences between them. The theoretical background of the thesis defined basic concepts such as the definition of education, education in nursing, a profession, and attitude towards a profession. Documents related to education since the foundation of nursing education to the present were also used and studied. The chapters on the status of nursing staff and its employment chances focus on the development of the relationship to the profession and shaping attitudes towards it. In the research part of the thesis, the collected information related to education and derived from archival documents, literature, laws and regulations is presented. The results can be used as a basis for creating educational material focused on the history of the field and intended for the education of paediatric nurses to strengthen their identification with the profession. The thesis also presents interviews with in-service paediatric nurses where they express their views on the work in the field and their attitudes towards their profession. The results of the interviews are documented and organized so that it is possible to assess whether there are any differences between these groups. The anticipated differences can be used for further investigation focused on attitudes to the profession. Verified knowledge could then be used for training paediatric nurses aimed at creating desired attitudes towards the profession.

Nutritional care about immobile patient on standard department of internal type
AMBLEROVÁ, Michaela
Nutritional care for immobile clients at a standard department of internal type becomes still more important, because nutritional care is important for maintaining good health and supporting quality of life. Nutritional status of immobile clients is very important to diagnose as early as possible in order to avoid all risks of potential complications. Adequate nutrition is also very important to maintain good mental health. The central objective of this work was to explore the specifics of nursing care in the field of nutritional care for immobile client at a standard department of internal type. Following this goal, three research questions were set up: How is the nutritional status of patients at a standard department of internal type assessed? What are the possibilities of application of nutrition for immobile client at a standard department of internal type? What are the specifics of nursing care in the fields of nutrition of immobile client at a standard department of internal type? The empirical part of the thesis was processed using qualitative research, which was realized through semi-structured interview technique. The interview contained 3134 questions, which focused on nutrition care for immobile clients on standard unit of internal type. The research sample consisted of nurses working in the standard department of internal type in the České Budějovice Hospital, a.s. Overall, this study leads to two findings, both positive and negative. Within the positive findings we can say that nurses provide adequate care in the application of nutrition per os. Negative findings relates to the fact that the interviewed nurses provide only basic care in case of the introduction of enteral and parenteral nutrition. They do not know more detailed specifics of enteral and parenteral nutrition. Based on this finding, we think it would be useful to organize regular seminars and trainings for nurses to expand their knowledge about this type of care, or at least remind it. This thesis can serve as an informational material for nurses in practice or students of other health professions. This work can serve also as a basis for further research.

Stress situations and nursing personnel
MAREŠOVÁ, Lucie
This thesis deals with the stressful situations in the profession of the nursing staff. The occupation of the nurse belongs to the most demanding ones. In this occupation, the nurse is permanently affected by many stressors of different types. She faces death, the suffering, dying and incurably ill people very often. She is there in times of pain, agony and suffering. Personal encounters with these difficult situations require highly professional approach but most of all, they present immense work stress for the nurse. The theory section describes mainly the stressful situations that are the most common and most difficult in the work of the nursing staff. The next part of the theory section describes possible consequences of the stressful situations and methods of managing them including the support by the management. This thesis has two objectives. The first objective was to map the manners used by the nursing personnel to cope with the stressful situations brought by their profession. The second objective was to find out the difference in the coping with the stressful situations between the hospital staff and hospice staff. The research section of this thesis contains the quantitative research done using the technique of an anonymous questionnaire with 20 question prepared by ourselves. The questionnaire was distributed to the nursing staff of all categories in the hospital and hospice care. It was completed by 269 respondents in total. The data was statistically processed using systems Microsoft Excel 2010 and Software R, version 3.0.2 (Chi-squared test, Fisher´s exact test, and Wilcoxon test). We determined four hypotheses. H1: Manners of coping with the stressful situations depend on the qualification of the nursing staff reached; not confirmed. H2: Manners of coping with the stressful situations are influenced by the length of practice of the staff; not confirmed. H3: Manners of coping with the stressful situations differ between the hospital staff and hospice staff; confirmed. H4: The nursing staff views their own mental hygiene as more efficient than the support from the management concerning the coping with the stressful situations; confirmed. The research results show that the nursing staff faces the stressful situations very often. They see as the heaviest stress the care of the suffering and aggressive patient, conflicts with the patient´s family, conflicts at work and workload. The manners of coping with the work burden which proved as the best for them are relax, rest and sleep. There were no differences proved in the manners of coping with the stress among respective members of the nursing team. Nevertheless, the coping with the work burden of the nursing staff in the hospital and hospice care is different. A minimum of the respondents notices any support during the stressful situations from the employer. On the other hand, certain support by the management could be viewed in the form of trainings, supervision or contribution to a "recovery" which are granted to the respondents from the employer according to their answers. However, the respondents would prefer, as the support by the management, the increase in pay or more days off. The respondents view as insufficient the preparation of the graduates for the future stressful situations in their profession, as well. They would recommend mainly various trainings dealing with the stress and its management. A good solution to alleviate the work burden of the nursing staff and quality enhancement of the services provided could be investments into better work conditions, both in terms of sufficient human and material resources and the very organization of the work processes.

How to prevent the proliferation of Legionella pneumophylis in hot water in the hospital Czech Krumlov
TUREK, Jan
This diploma thesis deals with microbiological quality of hot water in a hospital in Cesky Krumlov as well as hot water piping condition with respect to Legionella. It also deals with arrangements for improving the quality of hot water in this hospital. The subject and target of this thesis are the findings of the mentioned parameters based on own observations, technical documentation and analysis of warm water performed by an accredited laboratory. The hospital in Cesky Krumlov, the construction of which began in 1909, was built in 1911 as the 'Nemocnice Císaře Františka Josefa I.' As the time went by, new buildings were built up. The hospital was renamed to 'Všeobecná veřejná nemocnice' in 1942. In the following years the hospital expanded until the current condition. Water quality and presence of Legionella is a world-wide issue, which we must fight against. The thesis is divided into two parts. First, theoretical part, which includes both general and specific knowledge about Legionella, its health risks, the environment in which it occurs, possibilities of eliminating, suitability of the material for hot water pipes, gained in professional literature and a part of the Czech legislation dealing with public health protection, the law 'No. 258/2004 Coll.' in actual version and quality of drinking water and hot water. In the second, empirical part, I focus on the situation of the hospital in Cesky Krumlov from 2009 till 2015, concerning newly built boiler room and the whole distribution system of hot water regarding Legionella. Particularly I focused on materials used for ecologisation of the gas boiler room and materials used for hot water pipes and actual state of water distribution in individual buildings of this health care facility. I mentioned the analysis of the water samples performed by an accredited laboratory with corresponding technical documentation, which concerns the water distribution system, provided by the medical facility. I used secondary data analysis to evaluate these documents. Regarding the results from 2009 to 2015 the microbiological quality of warm water doesn't meet the limits defined in the Attachment No. 3 of the above mentioned law Order 252/2004 Coll. Limit value for colony forming units of Legionella is set to maximum of 100 CFU. In most of the samples this limit was exceeded by series of units up to hundred thousands of units. The last results in 2015 prove improvement of the unfavorable situation. In that year the analysis was tested three times. First in February, where the CFU units were 'only' in hundreds, with the top value of 550 CFU in the Postacute Care ward. Second analysis was performed in June that same year. Results were acceptable. The highest value was 64 CFU. Last analysis in the hospital was performed in December. Increased concentration of Legionella was again in the Surgery building. There were established of 1400 colony forming units. There were 300 CFU in the Postacute Care ward and the limit value of 100 CFU was in the ward of Internal medicine. The answers to research questions 'How to prevent reproduction of Legionella peumophylis in the water distribution system of the hospital in Cesky Krumlov?' and 'How to ensure a sufficient amount of quality hot water in the medical facility?' are included at the end of the stated recommendations. A risk factor causing the fast reproduction of Legionella is the old water distribution system in most of the buildings and low water temperature of water leaving the boiler, which is 55°C. All mentioned results and evaluations are included in this thesis as well as attached pictures, which show the environment and situation within the Health Care Institutions.

The use of (nano)oxides for metal and metalloid stabilization in contaminated soils
Michálková, Zuzana ; Komárek, Michael (advisor) ; Luke, Luke (referee)
The main objective of the thesis was to evaluate the potential of selected Mn and Fe (nano)oxides for the stabilization of metals and metalloids in contaminated soils. The research was focused basically on three materials - commercial nanomaghemite (Fe III), nanomagnetite (Fe II,III) and a synthetic amorphous Mn oxide (AMO). The main aim of the work was to provide a complex view on the chosen stabilizing amendments regarding not just their direct influence on contaminants mobility and stabilization mechanisms, but also their stability and alterations in soil conditions together with influence on soil microorganisms and higher plants. Firstly, adsorption properties of the tested materials towards Cd, Cu, Pb and As were investigated. In this context, the most effective material showed to be the AMO reaching one to two orders of magnitude higher adsorption capacities than Fe III and Fe II,III under given experimental conditions. Interestingly, the rate of As(V) adsorption onto AMO was increasing with increasing pH as a result of high pHzpc of the AMO (8.1) and significant dissolution of this phase at lower pH values. As a next step, the influence of (nano)oxides on metal(loid)s mobility and other physico-chemical soil characteristics after application to contaminated soil was examined. Again, the AMO proved to be the most efficient in reducing mobile pools of Cd, Cu, Pb, Zn and As. On the other hand, Fe III and Fe II,III addition had generally less significant effects on contaminants mobility. AMO application further resulted in an increase of soil pH connected with AMO dissolution and unwanted decomposition of soil organic matter. When (nano)oxides alterations in soil conditions were observed, MnCO3 coatings were identified on AMO surface while no significant changes were recorded for Fe III and Fe II,III. As the MnCO3 formation was connected with increased AMO stability, AMO particles synthetically covered with MnCO3 coating (denoted as SM AMO) were prepared. Although the SM-AMO had a lower mass loss in soil than pure AMO, the stabilizing efficiency was almost the same for both materials. The differences in surface composition of both materials were decreasing with time as MnCO3 naturally precipitated on the AMO surface in soils while the SM AMO coating was gradually dissolving. When investigating the effect on soil microbiota, AMO efficiently promoted soil microbial activity while no significant changes were observed in the case of Fe III and Fe II,III. The AMO was also able to reduce the uptake of Cd, Pb and Zn by sunflower (Helianthus annuus L.), eliminate Zn phytotoxicity symptoms and increase biomass yield. On the other hand, toxic levels of Mn released from the AMO in an acidic soil were found in sunflower tissues. AMO application is thus recommended for contaminated neutral or slightly alkaline pH with a higher cation exchange capacity in order to avoid unwanted release of Mn. Finally, various types of AMO-biochar composite sorbents were recently prepared and field experiment focused on stabilization of Cd, Pb, Zn and As using studied materials is currently under preparation. The combined results from the thesis highlight the importance of a complex experimental approach dealing with all parts of the contaminated soil environment in order to obtain complete information about the efficiency and usefulness of any newly developed stabilizing amendment.
