Human impact on creating the landscape
Lainová, Dana ; Janků, Jaroslava (advisor)
This bachelor thesis focuses on the differences in landscape structure caused by human influence in nature conservation area Czech paradise. It guide us though period from year 1955 until the present. It take into consideration both the previous and current landscape form, as for land area, landscape character, plant and animal association and abiotic factors. Bachelor work describes particular human influence on forming aspect of this natural heritage. It focuses on forestry and forest cover situation, agriculture and farmland. It does not forget hunting and its related situation of wild animals, fish farming which means purity of water. It will occupies water management and its watercourses modification. Least but not last it concentrates on infrastructure and related development and structural engineering. Attention will be aimed at sewage management, industry and natural raw materials extraction. It has to be mentioned the areas of tourism, mountain climbing and recreation, which should be kept only in marked areas and in accordance with nature conservation. Based on findings from individual areas is possible to compare what an impact did a human being on forming aspect of landscape of Czech paradise from year 1955 until the present. Even for such short time of history, it can be observed large change in landscape character or species association. For the future it will be necessary to reduce intensity of landscape recasting and more focus on conservation of indigenous of this nature heritage.

Growing of rapeseed for energy purposes - impacts and context.
Charvát, Michal ; Kuchtová, Perla (advisor) ; Josef, Josef (referee)
Biofuels are generally based on biomass. It may be a waste biomass or biomass grown specifically. It is used as fixed or lump fuel, and also to as liquid and gas. Liquid biofuels are used both for energy purposes, ie to produce heat, electricity generation, but also as a motor fuels. In this thesis goes on biofuel purposefully grown, about oilseed rape and from it made liquid fuel, in this case of RME rapeseed methyl ester, which is a fuel of the first generation. The European Union expected that the use of biofuel will reduce CO2 emissions by up to 35% further premised that the development of biofuels will be a positive impact on local employment and it the both on direct and indirect. Further help diversify Europe's dependence on oil imports. They were introduced direct support for growers in order to exlarged the area where grew plants intended for biofuel. These direct resistances were abolished in 2010. Similar support was also intended for producers. Regarding rapeseed, peak in the sown area across the EU was in 2010, when it was sown almost 7 mil. ha, which is almost 3,5 times more than the original plan for the EU. Last year, it was only 6,45 mil. ha, but with higher-yielding rapeseed seeds. Similarly, increasing the sowing areas you can watch in the Czech Republic. Moreover Czech Republic is the fifth producer of rapeseed in the EU. In 2013/14 have been sown most ha rape, total 418,8 th. ha, but production was the highest in the following year due hectare yields, although with reduced the area sown. Yet is rape sown on 14% of cultivated land. We can not talk about drastically restricting cultivation of rape, even after termination direct aid. First, the price of rape is very decent and steady and almost half designated for industrial processing it is processed on RME. However, the system of cultivation is not good for the soil. Rape in plans crop rotation is ranked every two years mostly, but the best would be once for five years. The only assumption was confirmed by the EU, CO2 emissions are lower, but is also needed to count with the amount of N2O emissions, which this benefit is reduced. However on employment it had no effect, or rather negative. More jobs in agriculture provides livestock production and the like can be evaluated also process industry. Another problem is the destruction of ecosystems so that could be grown plants suitable for biofuels. It is a matter of developing countries, in our lands is it about the depletion of fertile land to cultivation fuel instead of food. First, it needed more to fertilize and use pesticides. But also in case of crop failure it is revenue designetid for biofuels producers is delivere even at the cost of food price increases.

Krouželová, Jana ; Bečka, David (advisor) ; Roman, Roman (referee)
Winter oilseed rape is the most important oilseed plant grown in the Czech Republic. During recent years, rapeseed sown areas rapidly increased due to its complex usage in industry. Similarly, the rapeseed oil gains importance which is used in food industry. The successful cultivation of rapeseed includes the right cultivation technology as well as the choice of suitable variety which will be the adapted to climatic conditions of location. There are over 600 varieties to choose from based on Common Catalogue of Varieties of Agricultural Plant Species from which is about 80 varieties commonly used in practice in climatic conditions of the Czech Republic. Suitability of these varieties and their yield are tested based on variety testing conducted by ÚKZUZ. The varieties which proved to be suitable based on previous testing are recommended for cultivation and placed in Recommended List of Varieties which helps farmers to orientate in new varieties in the Czech Republic.The aim of this diploma thesis is a comparison of the performance of selected varieties of rapeseed which were cultivated in semi-operational conditions in Humburky, Kralovehradecky region. In this theses yield, oil content, 1000 seed weight were compared. Two hypotheses were set: 1) Hybrid varieties reach higher height and yield 2) Oil content of liner and hybrids cultivars is equivalent Further these features were observed: plant height, pod number on the terminal raceme, stalk number on the terminal raceme, number of primary and secondary branches, height and length of yield floor and their correlation with yield. Cultivar Faktor KWS (hybrid) reached the best yield from selected varieties, yielding 5,02 t/ ha (119,2 % average yield). The average yields of liner and hybrids cultivars were almost equivalent (4,16 t/ha hybrids and 4,10 t/ha liner). The greatest difference between liner and hybrid varieties was observed in plant height. The hybrids reached 10 cm higher on the average than liner varieties. The second hypothesis about the similar oil content of hybrid and liner varietes was confirmed. Observed varieties reached both 43,3 % of oil content .

Cloud computing technology framework and reducing risks
Akrir, Khaled Ali Ahmed ; Havlíček, Zdeněk (advisor) ; Macák, Tomáš (referee)
The thesis investigates, in a qualitative way, the vectors that contribute to cloud computing risks in the areas of security, business, and compliance. The focus of this research is on the identification of risk vectors that affect cloud computing and the creation of a framework that can help IT managers in their cloud adoption process. Economic pressures on businesses are creating a demand for an alternative delivery of the model that can provide flexible payments, dramatic cuts in capital investment, and reductions in operational cost. Cloud computing is positioned to take advantage of these economic pressures with low cost IT services and a flexible payment model, but at what risk to the business? Security concerns about cloud computing are heightened and fueled by misconceptions related to security and compliance risks. Unfortunately, these security concerns are seldom, expressed quantifiably. To bring clarity to cloud computing security, compliance, and business risks, this research focuses on a qualitative analysis of risk vectors drawn from one-on-one interviews with top IT experts selected. The qualitative aspect of this research separates facts from unfounded suspicions, and creates a framework that can help align perceived risks of cloud computing with actual risks. The qualitative research was done through interviews with experts and through the survey to measure risk perceptions about cloud computing using a Likert scale. The decision-making model and the framework created by this research help to rationalize the risk vectors on cloud environments and recommend reducing strategies to bring the IT industry one step closer to a clearer understanding of the risks-tradeoffs implications of cloud computing environments.

Kolesnik, Tatiana ; Pletichová, Dobroslava (advisor) ; Brožová, Ivana (referee)
Small and medium-sized enterprises, including micro-enterprises are the foundation of the economy in all developed economies. Their importance lies mainly in the creation of employment opportunities, introduction of innovation, the development of the business environment, employment and hence increasing the competitiveness of the Czech Republic. Small and medium-sized enterprises can operatively react to the situation on the market and thereby meet the requirements of the customers. In the Czech Republic is made up of more than 1 million economic entities. The share of small and medium-sized enterprises in the total number of active business entities was in the year 2014 99, 84 %, the proportion of employees of small and medium-sized enterprises in the total number of employees of the business sector amounted 59, 39 %. Share of the value added in the GDP of the Czech Republic was 53, 11 % (MIT, 2014). To improve the prosperity of small and medium-sized enterprises and the removal of the negative, that result from the size of enterprises and the specifics of the business operates in the Czech Republic the Ministry of industry and trade and the Agency for the promotion of business and investment CzechInvest.
