Introduction: The positive effects of vitamin D on the human body are frequently discussed and investigated by numerous studies, both foreign and domestic, and its serum levels are closely monitored in relation to diseases. Vitamin D has positive effects on the immune system, influences intestinal calcium transport, is important for proper mental and physical development and growth of children, even during pregnancy, and helps prevent lung diseases. Objective: To evaluate the relationship between blood vitamin D levels and respiratory diseases in children. Methodology: Serum vitamin D levels and their relationship to respiratory diseases were also monitored in relation to gender and season (summer and winter). Sample: Blood samples were collected from 127 respondents aged 2 months to 18 years, including both healthy and sick individuals, for vitamin D levels. Data collection and processing for healthy children were approved by their parents (Appendix 1). Blood samples were collected over a period of two years at a healthcare facility in the South Bohemian region. The results were evaluated in two borderline groups, at 50 and 75 nmol/L. Furthermore, the vitamin D content of 10 diets of these children was processed and evaluated. The resulting values of vitamin D levels also included studied diets. Results: The results did not confirm the expected relationship between vitamin D levels and respiratory tract diseases in children in either borderline group at 50 and 75 nmol/L. However, partial effects on the respiratory tract were confirmed. Discussion: The author attempts to explain why the hypothesis was not clearly confirmed.

in English This paper looks into how climate change is being covered by newspaper media in two Global South countries and two Global North countries - India, the Philippines, Denmark and Australia. While there is some literature on who the main sources are in climate change coverage, as well as how frequently climate change is covered in different countries, there is less literature on how climate change is framed, and how this relates to who the main sources are. Analyzing articles from three newspapers in each country, this content analysis gathered data on what sources are being predominantly used in news articles, and further, how these articles are being framed. It was found that climate change has become a highly politicized issue in the media across most of these countries, and that the main voice in how climate change is becoming to be understood is politicians - except for in Denmark. At the same time, it was found that climate change is mainly being framed as an issue in need of action - except for in Australia.

This Master's thesis entitled "Social Media's Influence on Journalism" focuses on the effects new communication technologies, especially social media, has on journalist's. These effects are examined in regard to four major aspects of journalism - the individual, journalistic routine, work with information sources and ethical standards. The theoretical frame focuses on current trends in media, specifically social media, and the routines of journalists with a main focus on newsgathering and sorting of news. This has been strongly linked to gatekeeping theory. Qualitative research was conducted using Semi-structured in-depth interviews to answer research questions. Seven journalists, representing various facets of journalism, from a number of Czech daily newspapers were interviewed. The interviews were divided into four main parts to find out which social media platforms are used, how social media has changed routines, how social media is used as a source of information and how ethical standards may have changed. Open and axial coding was used to analyse the data obtained from the interviews. Results showed that journalists utilise social media at work on a daily basis and it has become an integral part of their routines.

Lesson preparation is an important part of teachers' profession, yet there has been little research focused on this topic recently. This work studied the preparation of geography lessons in Czechia with an emphasis on the use of internet sources. Based on the findings, criteria for an ideal geographic website for teachers were suggested. The data were collected in two ways: (1) on-line survey of ran- domly selected secondary school teachers (n=72), and (2) semi-structured interviews (n=6). The work indicated that lesson preparation greatly varies from teacher to teacher. In general, teachers do not change their lesson plans significantly, and thus the beginning of teachers' career is crucial for future teaching. Participating teachers spend on average about a quarter of their working time on lesson preparation and there is no apparent correlation between the time spend on lesson preparation and the teachers' age or the length of teachers' career. Furthermore, it was found that all participating teachers use internet resources during lesson preparation, particularly for search of updated infor- mation. The most visited websites are those offering maps and encyclopaedias (predominantly Wik- ipedia). The ideal geographical website should primarily offer ideas for teaching activities, as fully- prepared lessons...

This paper deals with the evaluation of renewable and alternative energy sources network interconnection and their impacts on the operation and stability of electrical network. The article shows the dependence of the voltage level magnitude in the point of common connection on the power factor of the renewable energy sources generator. The following part analyses, how the short-term power variation of the power plants (wind and photovoltaic) regarding the weather changes cause the voltage variations according to the generator operational mode. These variations negatively influence the distribution network operation and the power quality. The dynamic variations were simulated by the NEPLAN software. In conclusion the feasibility of the plant interconnection is evaluated respecting other important factors (flicker, ripple control signal damping, harmonic voltages content, protective relays function).
