Determination of snow covering using remote sensing data
Zelenková, Kateřina ; Potůčková, Markéta (advisor) ; Štefanová, Eva (referee)
Monitoring of snow cover extent is an often disscused topic during last ten years, mainly because of the global change of the Earth climate. This work focuses on snow cover mapping using remote sensing data and methods. First the potencial data and methods for determination of snow cover extent are analysed. The problem of snow and cloud distinguishing is also disscused. Based on the example of using data from senzor MERIS and AATSR (Envisat) is illustrated how this data can be used for operational snow mapping purposes in the Czech republic. The decision-tree-algoritm for the detection of snow and clouds was developed. The acuracy of clasificated images is evaluated using comparison with in-situ grand measurament data.

Optimizing Flow and Segregaton Properties of Lactose/Microcrystalline Cellulose Mixture for Tablet Compression.
Zámostný, P. ; Kreibichová, B. ; Hofmanová, D. ; Kulaviak, Lukáš ; Zelenková, K. ; Růžička, Marek
The present study deals with optimizing the flow and segregation properties of levocetirizine hydrochloride formulation, where the delay between homogenization and tablet compression was found to affect the tablet content uniformity. In addition to API, the base formulation comprised spray dried lactose monohydrate, milled lactose monohydrate 200 mesh, Avicel PH 101 microcrystalline cellulose, and minor excipients. Several alternative mixtures were prepared using the same total composition, but different grades of lactose and microcrystalline cellulose. These mixtures were then tested for the segregation behavior in an in-house segregation device and the flow properties using the Freeman FT4 powder rheometer. The segregation tests showed the grade of lactose is essential for mixture in-flow segregation. While SD lactose mixtures increased the API content in a direction countercurrent to flow, the milled lactose mixtures segregated API concurrently. Mixtures using both lactose grades showed combined effect, resulting in the least segregation due to the two segregation processes competing with each other. However, the segregation was extremely sensitive to ageing of the mixture. It was also found that each type of lactose causes a different flow regime of the mixture in process vessels. In order to improve the content uniformity of the tablets, it was found the volumetric flow regime of transport to tablet press is required as well as the aggregate formation should be prevented.\n

Changes in physico-chemical parameters of the Orlik reservoir selected tributaries
ZELENKOVÁ, Kamila
The topic of the thesis is determination of concentration of dissolved solids in water and seasonal changes in surface water chemistry for specific affluents of Orlík water reservoir. Water samples were collected on regular basis and analysed in a laboratory during one season (November 2014 - November 2015). The thesis is focused on monitoring of changes in phosphate and nitrate concentrations, in particular. The results of analysis indicate that measured concentrations of substances at monitored locations reflect generally measured data within the region. Concentrations of NO3-N peak in winter to early spring seasons, therefore seasonal changes do occur; differences between locations have not been proven statistically. As for the parameter PO4-P within locations downstream pond systems no significant statistic differences were identified. Values of PO4-P concentration are not primarily associated with agricultural activities but rather with local sources existing within the catch basin. It has been concluded from testing water quality upstream and downstream fish ponds that pond management had no impact on quality of water within the monitored locations in 2015; respectively no additional phosphor and nitrogen load was imposed on Orlík water reservoir

Eutrophic stress of the Orlik reservoir
ZELENKOVÁ, Kamila
Detection of potential sources of load eutrophic surface waters. Orlik dam is out of your water and energy purposes also used for recreational purposes. In recent years, recorded deterioration of water quality. It happens that it appears "Flower" water surface and increase algae. The content of this work was to monitor the changing state of water quality in reservoirs Orlik and its surroundings during the season. Parameters were monitored: conductivity, pH, oxygen, nitrates, and phosphates and during the season of 2013.

Nutrition in hospitals as part of comprehensive nursing care
ZELENKOVÁ, Klára
A nutrition of high quality should be an integral part of the complex therapy in all hospital facilities, disregarding these premises results in the decrease of the whole quality of the nursing care. A complex nursing care detects actual and potential health problems, determines priorities and defines the role of the nurse providing those. Nothing but a highly qualified and plan-based nursing care enables the nurse to satisfy the patients´ / clients´ needs. The purpose of this Bachelor thesis is to discover and determine the demands of the clients hospitalized in hospital facilities for alterations of the nutrition system, to map clients´ satisfaction with the food served and to find out , if the meals served in the hospital facilities complies with the clients´ needs. The research was realized in the Hospital Strakonice, inc.c. in the internal, surgery and gynaecological ward, in the form of a questionnaire inquiry. Six hypotheses have been determined, of which 5 were confirmed and one was refuted. The first hypothesis tested, whether the clients hospitalized in hospital facilities would appreciate an alteration in the nutrition composition. On the basis of a questionary investigation, the hypothesis was comfirmed. The second hypothesis estimated, if the clients hospitalized in hospital facilities would appreciate the possibility of the choice of the meals, according to the results, it is obvious that this possibility is welcomed by the clients and thus this hypothesis was confirmed. The aim of the third hypothesis was to find out, whether the clients are satisfied with the food served. The results point out to the fact, that for the most of the respondents, the taste, satiety and quantity of individual meals was inconvenient, the results concerning the satisfaction with the temperature of the served meals proved the patients´/clients´ satisfactuion. The third hypothesis was confirmed, because the larger part of the answers proved the dissatisfaction with the food served. The four hypothesis, whether the clients have different demands on the served meals according to their age categories was, after detailed comparison of the results, confirmed and the results point out to a definite difference with the older and with the younger respondents. The fifth hypothesis estimated, whether the clients evaluate the served food as inadequate to their needs. From the results it is obvious, that the sufficiency is superior to the insufficiency and therefore, the fifth hypothesis was not confirmed. The sixth hypothesis evaluated, if the clients have the need to provide themselves with the food outside the hospital facility, from the results it is evident that the clients really have this need and the sixth hypothesis was proved and confirmed. I will hand deliver the results achieved to the head nurse of the Hospital Strakonice, inc.c. and together we will try to realize these alterations that would increase the satisfaction of the patients/clients with the nutrition and meals in this hospital.

Primary Prevention in Care of Teeth
ZELENKOVÁ, Kateřina
I have chosen the topic primary prevention in dental care because I was interested in it and I think it is very up to date. Dental care has been under sustainable development and research provides new trends in this range. It is difficult for either dentists or patients to watch this development and notice everything what is new. Primary prevention in the dental care is a system of measures performed to stop creation of teeth and dental adnexa diseases. As primary prevention we consider health education, dental hygiene, keeping rules of healthy nutrition. The research work was focused on parents of young children who gather their relationship to the dental care and whose consistent training may influence their attitude for the whole life. The aim of my work was {\clq}q To investigate parents knowledge of the prevention of dental deseases at children`` and {\clq}q To investigate the attitude of parents to the prevention of dental deseases at children``. To realize my aims I used the technique of questionnaires. The research group was formed by parents of children in kinder gardens in České Budějovice. My research work was based on three hypotheses:`` Parents are informed about the prevention of dental deseases at their children``, {\clq}qParents teach their children how to perform the dental hygiene``, and {\clq}qParents visit the dentist with the children since their three years age``. All three hypotheses were partly proved. Parents knowledge should be focused mainly on basic equipment for cleaning, using correct technique of cleaning teeth and preventive examinations. This information should be provided by medics in surgeries, via leaflets, magazines, preventive programmes or TV programmes. Parents should take care about the teeth of their children since their infant age, motivate their children to the dental care, search for new information and visit a dentist with their children regularly. Both goals were accomplished. Results of this research work may be used in the practical life as a base for further research work. They may also be used for creation of information material or programmes to support preventive dental care. Kinder gardens where this research work was performed will be informed about the results and they can use it for creation or improvement of the dental care programmes.
