Eichler, Michal ; Hes, Aleš (advisor) ; Petr, Petr (referee)
This diploma thesis is devoted to the evaluation of the meaning and role of shopping centers in retail sales in the Czech Republic, using analysis performed. The SWOT analysis was carried out in order to identify strengths and weaknesses of selected shopping centers and to define their opportunities and threats. Further, some of financial indicators of given studied shopping centers were calculated and the resulting data were compared to each other in the monitored time period. On the basis of these results, it was evaluated a possible impact of the effectiveness of the law of corporations to shopping centers. In the next part, two retail format focused on food sale were compared based on financial indicators. The first format is represented by hypermarkets located in shopping centers and the second one by smaller retail units. The last section describes evaluation of questionnaire focused on consumer behavior of customers during food purchase and their preferences in choice a retail format.

Indicators of influence on the reproduction of the level and quality of milk production
Poláčková, Barbora ; Toušová, Renata (advisor) ; Petr, Petr (referee)
The aim of this study was to evaluate research of reproduction indicators on the level of milk production and the quality of the milk on selected farm. Materials for processing thesis were obtained on Oldřich Poláček´s Farm Hole. Mr. Poláček´s farm is located in Central Bohemia and manages 380 ha of arabe land. The farm bred Holstein cows, for now there are 190 dairy cows of this breed.
The indicators of milk production and reproduction were observed from 2013 to 2015. Results of the observed farm were compared with results of milk yield of Holstein cattle breeders association in the Czech Republic.
The data were analyzed and statistically processed using SAS 9.3 (SAS / STAT; 9.3, 2011). To determine the basic parameters of the files were used MEANS procedures and UNIVARIATE.
Evaluation of milk yield and indicators of reproduction was based on the results obtained from the recorded milk production of cows done by Holstein cattle breeders association and stable computer system AFIFARM. To evaluate the data were used 104 dairy cows, which had last two standardized lactation completed in the test years from 2013 to 2015 and 121 dairy cows, which had the first standardized lactation completed in 2014 or 2015.
For the milk yield were evaluated parameters of kilograms of milk per lactation, kilograms of milk per day, fat (%), protein (%) milk, depending on reproduction (days open, calving interval, age at the first calving) and lactation order.
Milk yield on the farm in 2015 was above the national average in Czech Republic. For dairy cows with the first lactation was up to 8 536 kilograms per standardized lactacion, for dairy cows with second lactation was up to 10 928 kg, and for dairy cows with third and more lactation was up to 10 864 kg. The average content of 3,71% fat and 3,28% protein.
The influence of lactation negatively impacted % protein (r = -0.278). Conclusiveness was on the significance level (P <0.001). The highest protein content was on the first lactation 3,40%, and lowest in the fifth lactation 3,20%.
Statistically failed to demonstrate the influence of the order of lactation on the milk yield per standardized lactation, kilograms of milk and % of fat content.
The positive effect was shown between milk yield per lactation in kg and daily milk yield in kg (r = 1). Conclusiveness was on the significance level (P <0,001). The lowest daily milk yield on the first lactation was (30,24 kg) with the production of 9223,06 kg of milk and the highest on the third lactation (47,43 kg) with the production of 14466,76 kg of milk.
Increasing of milk production per lactation had a negative effect on the % of fat content (r = -0,137), and % of protein content (r = -0.196). Conclusiveness was on the significance level (P <0.05). With increasing milk production declined % of fat content and % of protein content.
Statistically failed to demonstrate the influence of the milk production per lactacion on the open days and the calving interval.
Effect was demonstrated between the % of fat content and protein content in % (r = 0,501) at a level of significance (P <0,001). With increasing of fat content in%, increased also the the protein content in %. The lowest protein content (3,20%) was with a 3,66% of fat content. The highest protein content (3,40%) was with a 3,68% of fat content.
Age at first calving of dairy cows negatively impacted on % of the fat content of milk (r = -0,186). Conclusiveness was on the significance level (P <0,05). With age increasing at first calving declined % of fat content in milk.
There was also demonstrated a connexion between the standardized lactacion and days open (r= 0,227). Conclusiveness was on to the level of significance (P <0,05). With open days increasing the amond of milk per lactacion was higher.

Importance and possibilities of winter cereals utilization in organic farming
Valdmanová, Miroslava ; Capouchová, Ivana (advisor) ; Petr, Petr (referee)
Organic agriculture is not only a way how to produce food and feed raw materials in
friendly way , but also it has very important secondary and landscaping functions. Production
without chemical inputs into organic farming is very important, but in a broader sense it helps
this system to bring the landscape, to it is original and natural functions.
The most grown cereal in organic farming in CZ is common wheat., which in year
2014 reaches an average return 3,05 t.ha-1
, was grown on an area of 6 117 ha and structure of
the grain it took part 24 %. For winter crops after the decree takes for the following wheat,
triticale with the average yield 2,97 t.ha-1
in the year 2014 with area of 3 530 ha, it is in
aproximatelly 14% of the structure of grain crop in organic agriculture. Than rye followed by
achieved in 2014 the average yield of 2,90 t.ha-1
and area of grown 2 392 ha, it is structure of
the grain in organic agriculture less than 10%.
Monitoring and evalution of wider range of varieties of winter wheat in organic and
conventional agriculture has been pursued in the Research station of the Department of Crop
production in Prague - Uhříněves since 1994. The results of experiments can help ecological
farmers in better orientation in available varieties and to facilitate the selection of a suitable
variety for their needs. Parts this long term activities is also my diploma thesis.
As expected, in general cultivars of conventionals wals of growing reached higher
yields in our experiment - cultivars Tobak (B) - 11,6 t.ha-1
, Gordian (B) a Matylda (A) - the
same yield 11,0 t.ha-1
and the most low yield was in cultivars Bohemia (A) - 9,6 t.ha-1
, Annie
(E) a Cimrmanova raná (E) - both the same 9,8 t.ha-1
.
In ecological system was discover the most high yield in cultivars Gordian (B) - 9,5
t.ha-1
a Tobak (B) - 9,3 t.ha-1
, the most low than in cultivars Bohemia (A) - 8,0 t.ha-1
,
Cimrmanova raná (E) - 8,2 t.ha-1
a Annie (E) - 8,5 t.ha-1
. It is therefore clear, that in both
type of system of cultivation reached the most high and the most low amount of yield the
same cultivars. But is important to say , that good amount of results reached cultivars Evina
and Fabina too. Both are from quality group of E (mostly in ecological type of economy).
Cultivars which reached in our attempts the best results of yield, had the samet he best results
of healty test and on arganic area was no flattened.
The evaluation of quality indicators showed that the conventional method of
cultivation, the highest N-content in dry matter corn varieties Annie (E) - 13.8% and
Cimrman's early (E) - 13.2%; lowest then Seladon varieties (B) and Vanessa (C) - the two
identically 10.7%. The organic way of growing the highest content of N in dry matter corn
varieties observed in Cimrman's early (E) and Eve (E) - two identically 11.6% and
immediately behind Annie (E) - 11.5%. The lowest content of N in dry matter showed grain
varieties Tobak (B) and Vanessa (C) - the two identically 9.7%. In both systems, the
cultivation is evident in consistent trend of gradual reduction of N in dry matter from grain
varieties of quality Group E (elite) to a variety of quality Group C (other unsuitable for baking
process).
In case of Zeleny test achieved in the conventional system the highest values variety
Annie (E) - and 60.2 ml Cimrman's early (57.3 mL); then the lowest varieties Vanessa (C) -
25.3 ml and KWS Ozon (C) - 29.7 ml. The organic way of cultivation had recorded the
highest value Zeleny test for early varieties Cimrman (E) - 55.8 ml and Fabius (E) - 47.0 ml,
the lowest varieties KWS Ozon (C) - 24.7 ml and Vanessa (C ) - 19.0 ml. As in the case of N
content in dry matter-grains is also here in both systems growing trend decrease values SBV
test of quality varieties of groups E to a variety of quality group C.
In the event that organic farmers farmed in similar environmental conditions, such as
those on the Department of Crop production in Praha-Uhříněves and sought food quality
wheat, it would be him on the basis of our results, we recommended eg. a variety of Eve and
Fabius (both from a quality group E) which reached both good quality and satisfactory yields
of grain (in the case of a significant focus on quality and variety Annie and Cimrman's early -
both also quality group E). In the case of preference revenue would be recommended
varieties, some varieties of quality group B, for example. Gordian and Tobak.
The work was completed at the end of a brief comparison of the economy growing
wheat in organic and conventional systems. From this comparison came out better ecological
wheat (despite significantly lower revenues), mainly due to the significantly higher price,
a higher total subsidies and lower variable costs.

Effect of sowing rate on the yield formation and quality of spelt wheat in organic farming
Myšková, Radka ; Capouchová, Ivana (advisor) ; Petr, Petr (referee)
The area of cultivated land used for organic farming expands every year, as does consumer demand for organic food. Organic farming is a system of land cultivation without chemical inputs, because chemicals can have a negative impact on the environment, human health as well as health of farm animals. An important part of organic farming are also various sowing methods based on the alternation of a broad range of different crops. Dinkel wheat (Triticum spelta, also known as spelt or hulled wheat), is ideally suited for this system, as it is less demanding in terms of external environmental conditions than bread wheat (Triticum aestivum, also known as common wheat.
The aim of the bachelor thesis was to gain insight about the impact of the seeding rate on the yield and the consequent profit from dinkel wheat in organic farming. A second objective was to evaluate any differences in the values of selected quality indicators of grain, depending on the seed rate. Finally, on the basis of the obtained results, to choose the seeding rate which proved to be ideal in given conditions.
The results of our experiments with selected genotypes of spring and winter dinkel wheat and control varieties of bread wheat sown in different seeding rates (100, 200, 300, 400 and 500 germinable seeds per m2) in the organic way of farming in the Research Station in Prague - Uhříněves show that the spring genotypes of dinkel wheat had a peak of offsetting almost a month later, in comparison with the control variety of spring bread wheat. Winter genotypes of dinkel wheat had this peak of offsetting approximately two weeks later than the control variety of winter bread wheat.
Both dinkel wheat and the control variety of bread wheat from low seeding rates (1.0 and 2.0 million of germinable seeds/ha) offset more as expected, and simultaneously achieved a higher average weight of dry aboveground biomass and biomass of the roots per plant than plants of high seeding rates (4.0 and especially 5.0 million of germinable seeds/ha).
The evaluated genotypes of dinkel wheat compared to the control varieties of bread wheat were generally characterized by intense offsetting, higher weight of dry aboveground biomass, and especially higher weight of dry matter of roots per plant.
Achieved yields were negatively influenced by the course of weather conditions, especially by the drought throughout most of the vegetation period in 2015 - spring varieties of wheat, however, were affected by the drought far more than winter wheat.
Based on the resulting yields, we can say that in our experiment the spring genotypes of dinkel wheat had the highest yields in the seeding rate of 4.0 million of germinable seeds/ha, for winter dinkel wheat the best seeding rate was 3.0 million of germinable seeds/ha (however, variety of Rubiota had a high yield already with the seeding rate of 2.0 million of germinable seeds/ha). To specify the information, it is needed to obtain results from more years.
From the evaluated genotypes, the yield of white spring dinkel wheat slightly outperformed the control variety of bread wheat Granny and in particular the second genotype of dinkel wheat, T. spelta KEW. In the case of winter varieties, the yield of dinkel wheat Alkor outperformed the second variety of winter dinkel wheat Rubiota as well as the control variety of bread wheat Penalta.
The evaluation of qualitative parameters showed that genotypes of dinkel wheat outperformed the control varieties of bread wheat, especially in the content of N-substances and wet gluten content in grain dry matter. Both spring genotypes of dinkel wheat also achieved very good results in the Zeleny sedimentation test - both exceeded the minimum value required from wheat for bakeries (30 ml). Also winter varieties of dinkel wheat Rubiota exceeded this limit. The number of decrease was high in the evaluated varieties of winter wheat, while spring wheat was negatively affected by sprouting due to the rainy weather just before the harvest. The level of seeding rate had no effect on the values of qualitative indicators.

The food problem in Latin America
Ahrafenina, Kseniia ; Kuna, Zbyněk (advisor) ; Petr, Petr (referee)
The diploma thesis consists of theoretical and practical part. Theoretical part is devoted to the concepts and causes of food problem in general. In the practical part was given the social, geographic and economic characteristics of Latin America. Also was analysed the food problem in Latin America and were made suggests how to improve the food problem in this region.
Currently, the food problem is a very hot topic in the world as well as in some regions. Hunger and poverty are socio-economic problems, which combine with the food problem. There are many different causes of food problem. All causes can be separated into two groups: causes related to human activity and unrelated. The main causes associated with human activities are causes of population, poverty, religious causes, political conflicts, and the causes associated with nature: global warming and soil degradation. Natural causes unrelated to human activity have the primary influence on agricultural production. Various natural disasters and climate change can not be affected by people.
In order to solve the food problem requires the intervention of international organizations for providing financial and food assistance to those affected countries. A major role in the solution this issue plays mutual cooperation between countries around the world.

The Horn of Africa food crisis
Viazanková, Zuzana ; Kuna, Zbyněk (advisor) ; Petr, Petr (referee)
This work focuses on the Horn of Africa food crisis. The food problem is one of the largest and oldest problems of mankind. This problem is closely related to the problem of hunger and poverty. Lack of access to food, raw materials and water is reflected in higher tension and violence, which then results in various conflicts. The work provides a theoretical basis for this problem. The following section describes the causes of the food problem, such as population growth, lack of education, land degradation, climate change, natural disasters and the like. The practical part is focused on the analysis of statistical data on demographics, economics, poverty, foreign aid, foreign trade and agriculture of the Horn of Africa. In the last part of the thesis, there are outlined possible solutions of undesirable situation in which the Somali peninsula is located, among them an increase in the population's education, stabilization of population, the development of agriculture, change of ownership of the soil, economic growth, integration groupings and food programs.

Prevention of accidents at preschool age
PETR, Petr
Every year, more than 300 000 accidents of children occur requiring medical treatment or hospitalization in a hospital. Around 300 children die as a result of an accident every year. In comparison with other European countries, the Czech Republic occupies one of the worst positions as to frequency of accidents of preschool children. The objective of this thesis is to identify existence, quantity and scope of preventive activities in facilities designed for preschool children within the district of České Budějovice. The subject includes confirmation or rejection of a hypothesis whether there is a relation between the size of the town or municipality, frequency and scope of preventive activities. To verify the stated hypothesis, interviews were held in which the pedagogical staff of preschool facilities were asked questions concerning prevention of accidents in their facilities. Assessment of the interviews results did not confirm the hypothesis of an existing relation between the size of the town or municipality, the frequency and scope of preventive activities. In all visited facilities, preventive activities are carried out, focused on prevention of all forms of accidents. Preschool facilities directly in České Budějovice can visit preventive events organized by units of the Integrated Emergency System with less difficulties than facilities in the country thanks to better accessibility by the public transport. In spite of the mentioned difficulties, most of upcountry facilities participate in those events in close cooperation with the local Police or voluntary fire department. Some preschool facilities have their specific focus and programmes compared to the usual standard. In some of them they deal with drugs and tobacco prevention, other facilities are visited by students of PF JU with their programmes focused on prevention, still others present children thematically focused stories on CDs and DVDs. Other facilities, for example, organize a children{\crq}s day related with prevention in road traffic or organize a visit of ZOO joined with a lecture on how to treat animals. We can see as a certain gap in preventive programmes an absence of the central methodology for their organizing. Suggestion and recommendation for improvement of the situation could include completion of central methodology for prevention for preschool children which would include in its content and provide individual circuits and specializations on specific dangerous situations a child can get in. Another proposal for solution of the situation could be provision of preschool facilities with materials and aids for presentation of preventive education organized mostly in the form of games.
