Hygienic safety of outdoor playgrounds with sandbox
Abertová, Jana ; Borůvka, Luboš (advisor) ; Anna, Anna (referee)
Playgrounds represent danger of a direct input of hazardous substances into children`s organism, that`s why they require a special attention. The diploma thesis deals with hygienic safety of outside playgrounds with sandpits in scope of valid legislation and medical risks, which might be caused by contamination.
The aim of the thesis is to assess the level of microbiological, parasitical and chemical contamination and hygienic safety of sand in outside playgrounds with sandpits in Hradec Kralove.
To check the contamination, samples of sand were taken in outside playgrounds with sandpits destined for children in Hradec Kralove. Safety parameters of taken samples were rated according to notice No. 238/2011 Coll., about setting of hygienic requirements for swimming pools, saunas and hygienic limits for sand in sandpits of outside playgrounds. The evaluation of samples was concentrated on microbiological, chemical and parasitical contamination of sandpits, which was analyzed by Medical Institute based in Usti nad Labem. The influence of position of playground within the town (city center vs. outskirts), time of collecting samples and age of each sandpit were judged.
The sandpits in Hradec Kralove in the years 2014 and 2015 were microbially contaminated over established limits only in one case. Parasitical or chemical contamination was not found in any case.
Next conclusion is that sandpits at end of season are contaminated by microorganisms about 18 % more often than at start of season and at the same time that sandpits in city center are contaminated about 14 % more frequently than in outskirts. New sandpits are often contaminated by thermotolerant coliform bacteria than old sandpits. From the point of view of chemical contamination, sandpits in city center are more contaminated by chemicals, however statistical difference is not significant. The discovered values of sand at start and end of season were misrepresented by addition of sand in sandpits in the course of main season.
Sandpits in Hradec Kralove had a high level of hygienic safety, which is determined in law No 258/2000 Coll., about protection of public health.

Kovář, Jan ; Vorel, Aleš (advisor) ; Jakubíková, Lada (referee)
Reflects chemical communication of the Eurasian beavers density-dependence?
Almost all studies about population density describe certain dependency: with higher population density increased intensity of chemical communication. This is provided by many authors on different animal species. However this study showed that chemical communication does not reflects density-dependence of the Eurasian beaver. Explained variability of final model was r2 = 0.02586101, but with no significance for both variables. However some relationships were tested. Correlation between biomass (amount of consumed woody resources) and number of shelters (beaver nests) was not significant, but correlation between number of shelters and distance was positively significant. This lead to test the alternative special model (mc) where dependency of number of lodges and its changing distance was tested. This model was significant (p = 0.007182) and was discovered new relationship in population parameters of beaver populations: with increasing distance increased number of shelters.
Main focus of thesis was to study how the distribution and intensity of the chemical communication is related to parameters of population density. The result was: with increasing distance the intensity of chemical communication doesnt increase.

Route truck transport planning for company Blažek a synové s.r.o.
Němcová, Michaela ; Fejfar, Jiří (advisor) ; Kvasnička, Roman (referee)
This bachelor thesis deals with the planning of routes for truck transport company Blažek a synové. The aim is through appropriate economic and mathematical methods to find a suitable route, while that would be a minimal cost.
The literature review describes the basic terms on this topic. Primarily i tis focused on logistics and road car transport. There are also so described the methods by which it is possible to solve this problem.
Practical work is divided into two parts. First, it is assumed that the circuit will take a larger car that can carry all at once. Therefore, in this case, Vogel's approximation method is used and the best route for the company is chosen. In the second part, on the contrary, it is assumed that smaller cars must be taken so the route is divided into circuits. In this case Mayer's method is used, which divides the route into three areas. Again, the best route is selected.
In the end of this work there is evaluation. Assessing the financial terms and there is also a comparison of actual mileage of the routes used and calculated routes chosen methods. The comparison shows that the larger cars company save more money and also driving less kilometers.

Legal preconditions of the market economy
Grubner, Jan ; Kadlecová, Eva (advisor) ; Civínová, Denisa (referee)
The work describes and examines market economy and all legal forms of doing business in the Czech Republic in terms of suitability to set up a business. At first the market economy is defined and legal forms of business are described afterwards. There is also a comparison with other market environments. The market economy system in Germany has been chosen for these purposes. It follows from this comparison that although the German legal system offers other forms of business, which may seem more advantageous in some terms, Germany does not represent an offer attractive enough for businessman to decide for the German market instead of the Czech one. In the work, there is also a brief description of the conditions in European tax havens, which may be much more interesting for businessman.
The practical part of the work was carried out in a form of sociological research using questionnaires as the main tool. It focuses on the Czech businessmen´s views of the business conditions and environment in the Czech Republic. The research showed that the businessmen consider the business conditions in the Czech Republic to be relatively favourable, legally well-based and intelligible at the same time.

Formation of yield and dry matter with genetic resources of opium poppy (Papaver somniferum L.)
Slowiaczek, Lukáš ; Hnilička, František (advisor) ; Jan, Jan (referee)
Diploma thesis with the topic: Formation of yield and dry matter with genetic resources of opium poppy (Papaver somniferum L.) was worked out at the Department of botanics and plant physiology, Faculty of agrobiology, food and natural resources ČZU in Prague. The purpose of this thesis was to determine genotype and ontogenetic differences in amount of yield, production of dry mass, and value of growth-analytic characteristics in certain species of opium poppy. Diploma thesis was based on the fact that most of the studies about opium poppy (Papaver somniferum L.) are focused on the content of alkaloids and other substances present in poppy seeds. Due to this facts, it is necessary to describe the genotypes of poppy plants and their genetic resources from the physiological point of view.
Following species of opium poppy were chosen for the experiment: Akvarel, Albín, Buddha, Florian, Korneuburger Weisser, Lazur, Major, Marianne, Opál, Postomi, Sokol, Tatranský. These species were chosen according to their content of alkaloids, especially morfine very low content, low content, medium content and high content of morfine. All of the tested genotypes are tested as object of study of genetic poppy resources. Seeds were supplied by GB Oseva Pro s.r.o., o.z. VÚO Opava and company Český mák.
Field experiments were established at the research laboratory FAPPZ ČZU in Prague, in Červený Újezd. This location is in Prague-West division, in area of Middle Bohemia. The altitude of this location is 401 metres above the sea level. The size of the field for testing was 2 m2. The experiment was based in 4 repetitions by the method of Latin square. Winter wheat was used as the preceding crop. Opium poppy was planted according to agrotechnical principles of planting.
Content of dry mass in individual plant organs was measured in certain ontogenetic stages of opium poppy (35, 45, 49, 52, 54, 62, 81 BBCH). Size of leaf area was assessed by the image analysis WinDias. Yield of seeds was assessed as well. Growth-analytic characteristics were calculated from the values of wieght of dry mass and size of leaf area.
The results confirmed that the size of plants is influenced by its ontogeny and also by its species. The results also confirm, that the height of plants is not influenced by the content of morfine. Connection between the colour of seeds and height of plant was not confirmed either. Increase in weight of above-ground biomass depending on ontogenetic stage and influence of plant species was confirmed. There are differences in production of yield in species of poppy with different contents of morfine because the average weight of yield in species with very low content of morfine was 112,36 g, in species with low content of morfine 110,41 g, in species with middle content of morfine 12167 g and in species with high content of morfine 123,16 g. It was approved that ontogeny of plants influences the leaf area index (LAI) as it increases until blooming and then it decreases as a result of senescence and falling off the old leaves. Differences in leaf area index were detected among the species of opium poppy, depending on the content of morfine. It was detected that crop growth rate (CGR), relative crop growth rate (Rw) and relative growth rate of assimilation area (RA) are influenced by the ontogeny of plants. It was detected that species with high content of morfine in poppy seeds (Buddha, Postomi, Lazur) and species with white seeds Sokol and Albín have lower yield than species with middle content of morfine.

Participants in local development (Kácov, Chlum, Tichonice, Kladruby)
Jirků, Markéta ; Kocmánková Menšíková, Lucie (advisor) ; Pavel, Pavel (referee)
The main aim of this thesis is to compare and evaluate the importance of social activities, whether and how it contributes to quality and to the development of local life and local communities in the surveyed municipalities Chlum, Tichonice and Kladruby (municipalities under three hundred inhabitants) and compare the social activity of these municipalities with the thee times bigger township Kácov. The aim of this thesis is to find out the reason why smaller municipalities under three hundred inhabitants appear to be
as active as the larger township. The theoretical part defines the terminology related to the topic. The empirical part of the work consists of secondary and comparative data analysis of actors, activities, and community amenities. Secondary and comparative data analysis showed that social life in small municipalities is varied and rich especially
in entertainment, cultural and sport activities. Compared to the bigger township there is less folklore and education activities in smaller municipalities. It was found that the most active municipality is Kladruby with the activity ratio to population of 5,3%, followed by Tichonice with 3,6%, township Kácov with 3,3% and Chlum with 3%. It came out that there is not a direct correlation between the number of actors and social activity of the municipality. The activity of individual actors is different. It means that it is not the truth, that the more groups of actors are in the municipality, the more activities are held by the actors in the municipality. It was found that township Kácov disposes with the most diverse community amenities. Despite of a noticeable impact of community amenities on regularity of organizing activities, this factor is not the only condition for organizing activities. Deficiencies in community amenities can be partially replaced by well-functioning common organizing activities by actors, what is the factor what differentiate smaller municipalities from the large township. Exogenous approach was, over the last ten years, evident in all of the examined municipalities. There was obtained and invested financial resources to the municipalities community amenities, which allowed organizing new activities or continuing with organizing of existing activities. The empirical survey was carried out through semi-structured interviews with the actors operating in the public and nonprofit sector in the examined municipalities. A key factor in the activity organizing is community involvement connected with the mutual cooperation of individual actors (i.e. a combination of utilization of actor´s cultural and social capital). Smaller municipalities may not seem, to the interviewees actors, as active as three times bigger township. Reasons why smaller municipalities may seem as active as the larger township are more significant community involvement and a higher rate
of cooperation between actors in organizing activities in smaller communities. The social life plays an important role in all of the examined communities - especially in creating
and maintaining interpersonal relationships, in strengthening social cohesion, preserving the traditions and creating the relationship with the place. It was found and confirmed how important endogenous approach (active actor) in development of examined communities is. With the proper supplementation and harmonization with exogenous approach
can be the endogenous approach further stimulated.
