The Decline in the Standard of Living in Presenior (55-65 years) and Senior (65+) Generation and the Factors that Influence Them
Durkáč, Ondřej ; Šefčíková, Linda (referee) ; Konečný, Štěpán (advisor)
Senior policy of the state is largely focused on the active life of seniors (eg national strategy to support positive aging for the period 2013-2017 ). From this pont of view is generally expected to stay seniors longer in their natural environment and any subsequent use of social and health services, residential care homes for the elderly. Another phenomenon is the senior policy burden on the state budget in raising funds for the payment of pensions. One means of this policy mainly at regional level is to support seniors through discounts and other advantages Senior Pas project. The author draws a comparison of the consumer basket of the general population in the age structure from 55 years and above users Pas Senior Discount Network , which is primarily intended to support active living. The theoretical part focuses on the description and benefits, deficiencies discount networks in general and the discount network designed primarily for seniors. Thesis will also undertake an excursion to the neighboring countries, especially Austria and Germany, this excursion could give a number of inspiring suggestions in monitoring the functioning of these networks. In the practical part, thesis will devote particular network Senior Discount waist and through a questionnaire survey of members of the network. Thesis will be noticing all the available factors affecting the selection and use of discount networks in relation to age, place of residence, gender and other attributes/parameters. Thesis will help to answer the question whether discount network tends to increase the active life of seniors primarily or secondarily through capital cost savings for common services and goods. Author of acquired knowledge and experience will provide recommendations for fulfilling the mission and good functionality of discount network Senior Pas.

Building insulation influence on heat consumption
Langer, Jiří ; Košner, Jan (referee) ; Hejčík, Jiří (advisor)
The aim of this work is to study heat consumption and to specify real savings of heat after applying thermal insulation. These real savings will be compared with the savings, which were theoretically quantified. Main part of this thesis studies different types of thermal insulation and ways of applying of the thermal insulation. The histogram, which shows savings from settlement units at Vinohrady, Líšeň, Kamenný vrch and Slatina is also part of the thesis. Schema, which shows tendency of correct, ordinary and incorrect thermal insulation can be also found in this work. We analyze teoretical solution of savings on street Oblá no. 56 with real measurements.

Computer Network Design
Bafrnec, Luboš ; Synáč,, Jaroslav (referee) ; Ondrák, Viktor (advisor)
The subject of the “The Computer Network Design” thesis is the analysis of the current company status and a detailed analysis of its possible improvement. The present status, company demands and the brief summary of available technologies for proposed solution have been described. The optimal option for the company has been chosen. Current company costs have been analyzed and savings solution for both monthly costs for maintaining the network and purchasing cost for computer technology itself.

Investigation of impact of radiant heating and cooling on car driver thermal comfort
Pavlík, Vojtěch ; Tuhovčák, Ján (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on the matter of radiation heating, thermal comfort maintenance and setting optimal operation parameters for heating system equipped with radiation panels. The research section summarizes the effects most important for thermal comfort, methods of its determination, heat exchange distribution between the human body and its environment, and technical possibilities of heating car interiors. The central points of this work are the simulation of car interiors heated with radiation panels and the evaluation of thermal comfort with a virtual mannequin. Thermal state was determined via the equivalent temperature and thermal comfort zones diagram (method by O.H. Nilsson). Forty-two simulated scenarios led us to conclude that thermal comfort is not possible to obtain with panels exuding a maximum temperature of 43 °C and the combination of several heat sources is required. Nevertheless radiation heating considerably contributes to energy savings without the loss of thermal comfort in assessed car.

Evaluation of the Economic Efficiency of the Vineyard Planting
Vitouch, Jan ; Osička, Karel (referee) ; Ptáček, Roman (advisor)
The aim of this bachelor thesis is to economically evaluate the effectiveness of the investment project of Winery X from Hustopece to planting the vineyard and compare it with the alternative variants of the implementation of this project with respect to the findings. The result of this comparison will then be the design of the optimal variant of the investment in the planting of vineyards for the Winery X. The bachelor thesis has two basic parts. The literary research introduces the problems of viticulture with a focus on the issue of obtaining raw materials for wine production and evaluation of investment efficiency. The actual work consists of quantification of capital expenditures and operating costs associated with grape acquiring and harvesting. In connection with the above objective, the costs, the return on investment, the net present value of the investment, and the internal rate of return to the different possibilities of wine grape acquiring are also evaluated.

The possibilities electricity savings of refrigeration and cooling equipment according to the distribution rate - the cold storage
Pálka, Marek ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This bachelor´s thesis is focused on the possibilities of electricity savings of the freezing equipment, which would work only in low distribution rate and it would be disconnected from the power source in the high distribution rate. In this work, a total research in the field of refrigeration and cooling equipment, both technological circuits, as well as the principles of temperature regulation and food storage process is made. Another part of the work is focused on freezer testing standards and regulations. Much of the work is devoted to the experimental measurements, in which different types of rates on the given freezer equipment and with them associated the possibilities savings relative to other rates are measured. Another objective of the experimental measurement is to find out the temperature behaviour in the various parts of a freezing apparatus according to the switching time of the rates. There are overall experimental measurements evaluated and the possibility of electricity savings in direct reliance to the processes ongoing in the food during long term storage in the freezer in the unstable storage temperature In the conclusion of the work.

Structure of savings of Czech households with a focus on investments
KUBAL, Vít
The main goal of this diploma thesis is to evaluate the structure of savings of Czech households based on the developed analysis. A secondary goal is the proposal of measures to improve the current situation. The first part of the work mentions various theoretical perspectives on the problem being solved. Subsequently, using own analysis, this work evaluates the rate of savings of Czech households, and especially their structure. The own analysis also includes two foreign studies that serve as a basis for research in the Czech Republic. Last but not least, the work contains a questionnaire survey that deals with the consumption behavior of the respondents as well as their knowledge in the area of investments. On the basis of a questionnaire survey, the hypotheses established by the author of the thesis on the basis of research questions are verified using statistical testing. At the end, the results of the own analysis are clearly summarized. The author concludes the work with his proposal for improving the current situation.
