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.

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.
