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.

Quartz and other siliceous materials are among the most widely used industrial raw materials. Demand for high-purity silica increased during past decades, specifically due to its growing use in the photovoltaic energy or electronic/electrical industries. Strict requirements on the purity of the feedstock, together with very complex processing technology, narrow down the choice of potential sources suitable for industrial extraction and use. This bachelor thesis provides an overview of the existing knowledge concerning the formation, properties, and processing of industrially exploitable deposits, and the market policy of high-purity quartz raw materials. This comprehensive overview is followed by a section that focuses on deposits and potential sources of high-purity quartz raw materials in the Czech Republic (Bohemian Massif). This part was elaborated on the basis of publicly available archival sources (final exploration reports or reserve calculations), available in the Czech Geological Survey - Geofond.

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.

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...

The current state in research of economic systems is characterised by two prevailing issues. Firstly, study of economic systems is traditionally based on analytical and econometric tools, which have been the main arbiters of the veracity or plausibility of assumptions and hypotheses in economics. This approach has been proved to be highly suitable for theory development. Secondly, practical issues and necessity to support decision-making led to development of various modelling and simulation techniques or tools. However, majority of these approaches usually fail when coping with complexity. Furthermore, several main areas of interest can be identified in the business and economics modelling. Nevertheless, these areas are mostly independent due to their problem- based focusing on particular issues and their solutions. Depicted gaps might be bridged with the help of new modelling paradigms that have been established only recently. Application of agent- based modelling in the realm of economic systems is labelled as Agent-based Computational Economics (ACE). In particular sections of this paper results of experiments run on the novel model are described. The model is based on agents, which are described as a vector of several observed parameters, and four types of agents are used, namely consumer agent, factory agent, mining agent, and transportation agent. In addition, a colony is added as the fifth type of meta-agent. Scalability and configuration options of the model enable for various configuration and thus for conducting specific experiments. The presented system is already implemented as a prototype version in the NetLogo environment. The paper depicts two example scenarios, resource production and resource proximity, and offers interpretation of achieved results. Since most of the work done so far was focused on individual agents, group perspective as an important extension of ACE modelling is suggested as the further research and development direction.
