Hák, Tomáš ; Kokštejn, Jakub (advisor) ; Hojka, Vladimír (referee)
Title: Short-term intervention in the development of speed in football Objectives: The work objective is to assess efficiency of speed intervention at categories of Under-13 and Under-14 of the football club FK Pardubice. Methods: The group observed contained players aged 13 and 14. Total number of players was 23 (n= 23, 13,2 ±0,3 year). In order to verify the efficiency of the interventional program, which took 6 weeks, a 20 m shuttle run, a change-direction run with and without ball were used. The data were gathered with 2010 programme and processed according to Statistica statistical programme. Results: After 6 weeks of a motion intervention the experimental group did not show any significant progress. The group not involved in the motion programme did not make any progress. In rare cases, even a slight deterioration occurred in both groups. Based on results stated below we declare that the program chosen was not efficient for speed development at the categories of U13 and U14 of the club of FK Pardubice. Keywords: football, academy, motion intervention, speed

Water footprint of the cow milk for two types of production systems in the Liberec Region
Hojcsková, Daniela ; Hák, Tomáš (advisor) ; Třebický, Viktor (referee)
The water footprint is a multidimensional indicator which was created to quantify the total volume of freshwater used for various purposes. With the water footprint it is possible to determine the volume and type of water used directly and indirectly during the production in a given place and time. The data related to the water footprints of products are utilized in the evaluation of the international trade with goods, too (a concept of virtual water used for the analysis of water stress export out of the country which imports water-intensive products). The greatest amount of water is used globally in the agriculture, so the agricultural products are the ones with the highest water footprints. The focus of concern is the water footprint of an agriculture production and the aim of this work is to bring the first results regarding the water footprint of the cow milk in the Czech Republic and also to evaluate a methodology of its calculation. Two dairy farms dealing with a market production of milk from the Liberec region were chosen for the research. The farm Rváčov is oriented to an intensive milk production and on the other hand the farm Bzí is a system with mixed elements of extensive and intensive characters of the dairy production. For the comparison of the milk production effectiveness we have...

Consumption of selected agricultural commodities in Czechia and its impacts on water resources in producing countries
Nováková, Petra ; Hák, Tomáš (advisor) ; Stojanov, Robert (referee)
The thesis is focused on the relationship between food consumption and environmental impacts on places which are often very distant from the where the consumption itself occurs. Food consumption through the international trade causes pressure on water resources in different countries. The thesis analyses the water footprint from geographical perspectives, specifically focused on national consumption of two selected crops, with an emphasis on external water footprint. The main objective is to evaluate the impacts of consumption of selected imported crops on water resources in producing countries by comparing the differences of the impacts in these countries. To evaluate these impacts, new method of revised water footprint is used. This method connects the water footprint and impact assesment on water resources. In the first section the thesis is devoted to the description of the current state of water resources in different regions of the world, water use in agriculture, international flows of virtual water and theoretical concepts of water stress and water footprint. In the next section, suitable crops are selected and the water footprint of national consumption is quantified. The following section deals with the water footprint revision and assessment of impacts on water resources in the world,...

Analysis of the Commitment to Development Index
Syrovátka, Miroslav ; Hák, Tomáš (advisor) ; Nováček, Pavel (referee) ; Šauer, Petr (referee)
Analysis of the Commitment to Development Index Miroslav Syrovátka ABSTRACT The Commitment to Development Index aims to measure the effects of wide range of rich countries' policies that support or limit development prospects of poor countries. These policies are grouped into seven components of the index. The thesis analyzes and assesses the methodology of the index construction with the main focus on its environmental component. It is argued that although the environmental component is a legitimate part of the concept behind the index, the difficulties of its implementation limit its information value. This is due to the specific shortcomings of component indicators and the necessity to combine environmental policy indicators with indicators of exploitation of global environmental resources. The scores of Visegrad countries and correlation analysis show the specificity of the environmental component within the whole index and indirectly support the conclusions about its reduced information value. The thesis discusses the options for modification, both at the level of composite index construction and presentation, and at the level of individual indicators of the environmental component.

Material Flows and Environmental Impacts of s-WEEE in the Czech Republic
Polák, Miloš ; Hák, Tomáš (advisor) ; Kočí, Vladimír (referee) ; Vladík, Jaroslav (referee)
This thesis is a comprehensive study describing and quantifying material flows of waste electric and electronic equipment (WEEE) in the Czech Republic; specifically the material flow of small waste electric and electronic equipment (s-WEEE) as well as representative substances. The studied material flows were estimated regarding aspects of the environmental impact. The End-of-Life mobile phone is seen as a typical representative of s-WEEE ; therefore material flows of mobile phones are described in this thesis as well. To put it in concrete figures, approximately 124 thousand tons of WEEE from households originated in the Czech Republic in 2010, where each inhabitant got rid off 4 pieces of WEEE in average. Further, total production calculating also consumer-like WEEE from companies and institutions was around 141 thousand tons in 2010. S-WEEE present around 15% from the total amount of WEEE originating in 2010; however it is more than 80% as regards the number of pieces. Despite of that fact the recycling potential of Au for instance is slightly higher by s-WEEE than by large WEEE (63kg/year compared to the 59kg/year respectively). As regards estimation of the total production of EoL mobile phones, around 45 thousand pieces originated in the Czech Republic between the years 1990-2000 and 6,5...

Environmental assessment of the Czech Republic based on Water Footprint
Žlábková, Jana ; Hák, Tomáš (advisor) ; Vačkář, David (referee)
This dissertation sets its goal in application of the water footprint indicator, which is a practical and multi-layered indicator of water sources consumption. Of human activities, agriculture presents the most significant demands on water sources consumption. Therefore I have turned my focus to the widely-discussed issue of biofuels production, because the input materials for production of this kind of energy are agricultural crops (in the Czech republic those are: oilseed rape, sugar beet, Indian corn and winter wheat). The calculated results of water footprints of the selected industrial crops (m3 /t) and of water footprints of the heating value units of that crops (m3 /GJ) offer us a concrete notion of energy requirements of water of that chosen industrial crops in the conditions of the Czech republic. Keywords: water footprint indicator, biofuels, oilseed rape, water consumption, biodiesel, bioethanol, evapotranspiration.

Water Footprint. Calculation of water footprint of wheat, maize, sugarbeet and tomatoes in the Czech Republic
Landová, Lucie ; Hák, Tomáš (advisor) ; Vrba, Jaroslav (referee)
Fresh water is a renewable resource but it is also finite. Around the world, there are now numerous signs that human water use exceeds sustainable levels. Groundwater depletion, low or nonexisting river flows, and worsening pollution levels are among the more obvious indicators of water stress. Satisfying the increased demands for food, water, and material goods of a growing population while at the same time protecting the ecological services provided by natural water ecosystems requires new approaches to using and managing fresh water. There has been little attention to the fact that the organization and characteristics of a production and supply chain does actually strongly influence the volumes of water consumption and pollution that can be associated with a final consumer product. Uncovering hidden link between consumption and water use can form the basis for the formulation of new strategies of water governance. That is why in this diploma thesis we focus on introducing the indicator of freshwater use that looks not only at direct water use of a consumer or producer, but also at the indirect water use - water footprint. At a global scale, most of the water use occurs in agricultural production. That is the reason why we have chosen water-intensive goods like crops to show how water footprint...

Relevance Assessment of Selected Sustainability Indicators
Vilhelmová, Zuzana ; Hák, Tomáš (advisor) ; Třebický, Viktor (referee)
Sustainable development research makes use of various indicators for environmental monitoring without really focusing on quality and comparability of these indicators. This paper tries to lay down method of assessment of one of these indicators - the relevance. My method will be used for evaluating the indicators of ECI set - European Common Indicators, ten indicators of the Sustainable Urban Development, established by European Commission in cooperation with European cities. My method of evaluating the indicators is based on searching the keywords. One set of the keywords was specified for each indicator of ECI set and several sets of the keywords were specified for every indicator's theme. I collected data to establish three types of relevance - public, scientific and political relevance. Data for the public relevance were searched on World Wide Web by search engine Google, data for the scientific relevance were searched in the Google Scholar database and data for Political Relevance were searched in several official documents related to sustainable development. Public and scientific relevance were determined as a proportion of number of present keywords for the indicators and for their topics together and number of present keywords for the topics alone. Political relevance was determined as a...

Life cycle assessment of buildings
Mrkvičková, Kristýna ; Kočí, Vladimír (advisor) ; Hák, Tomáš (referee)
This bachelor thesis is focused on life cycle assessment of building construction. All impacts will be modeled on residential house in professional LCA software. Every single component of the building was evaluated with regard to their impact on enviroment. The output list each category of indicators and evaluation of the impact. It shows which environmental categories are most affected by building and where it would be useful to optimizme it. The family house presented by the typical new building was chosen for evaluation process. The product system was simulated by the GaBi 4 software tool, then it was evaluated using the impact categories of the CML 2001 - Nov. 09 characterization model. The theoretical part deals with the LCA methodology, explains the different stages and describes categories of impact. Furthermore, the global trends are discussed in terms of assessing the building lifecycle. At the end, the LCA study has shown that the biggest influence on the environment is caused by the service life of a product's lifecycle and water treatment contributes the most on this result.

Corporate social responsibility: strategic advantage and relationship with financial performance Case study from the Czech republic
Müllerová, Michaela ; Hák, Tomáš (advisor) ; Kašparová, Klára (referee)
The corporate social responsibility is a voluntary concept of firm's embrace of responsibility for the impact of its activities on the environment and society. The corporate social responsibility is the brand and guarantee that firm runs its activities not only within the law and ethical standards, but goes far beyond the law and moral values. Firm demonstrates its social responsibility through engagement in social issues, substitute for the state in support of underprivileged or disadvantaged groups, but also develop activities which have positive impacts on the environment, advocate and meet ethical business principles, take care of their employees, to distance themselves of corruption and bribery, etc. This thesis deals with the objective introduction of corporate social responsibility concept from its origin to contemporary approaches. The thesis introduces related theories which contributed to corporate social responsibility as well. In addition, this thesis familiarizes with the open question of relationship between corporate social responsibility (performance) and firm's financial performance and presents the important empirical research in this area. Results of analysis, done in this thesis, indicate a slight negative relationship between corporate social responsibility (independent...
