Pelikánová, Denisa ; Šerák, Michal (advisor) ; Vojtko, Tibor (referee)
The bachelor thesis focuses on elderly people as participants of education and their usage of the information and communication technology (hereinafter referred to as ICT). The aim of this work is to analyze the frequency and reasons for using ICT by a specific group of elderly people. The thesis is divided into four chapters. First, the main concepts of age, aging, and changes in aging will be reflected. Attention will also be paid to the demographic development of elderly people. Furthermore, the work focuses on the concept of the information society, the digital divide, and digital literacy. The third chapter deals with the digital literacy of elderly people, motivation, and barriers in the usage of ICT and specific reasons for usage ICT by elderly people. The last chapter focuses on an empirical survey which analyzes the frequency and reasons for the usage of ICT by the participants of education. Klíčová slova v angličtině: digital literacy, digital divide, ICT, information society, elderly people, old age

Health risk assessment of chemical substances from removing of old environmental loads Introduction. Hazardous wastes from refineries stored in lagoons are old environmental loads. One way of remediation is to extract and process this waste to an alternative fuel. Emissions of harmful substances released into the atmosphere during extraction and processing of waste can negatively affect the health of exposed persons. Aim of this study was to evaluate the potential level of health risks from remediation of old environmental loads based on the detected concentration levels of selected substances in the air and to build a view of potential health risk stratification in the wider area. Methods. Among the contaminants were monitored sulphur dioxide, toluene, hydrogen sulphide and 16 representatives of PAHs (acenaphthene, acenaphtylene, anthracene, benz[a]anthracene, dibenz(ah)anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, benzo[a]pyrene, fluoranthene, fluorene, chrysene, indeno[1,2,3-cd]pyrene, naphthalene phenanthrene, and pyrene). For that purpose was used combination of air pollutant concentrations and the dispersion model of substances in environment. The monitoring of contaminants was realized in the place of old environmental loads and in the nearby residential area....
