Černý, Vítězslav ; Flemr, Libor (advisor) ; Vojta, Zdeněk (referee)
Title: Comparison of the operation of selected ice stadiums in Prague. Objectives: The aim of this thesis is to compare selected ice stadiums to each others by using analysis. Furthrmore, the thesis should show the opportunities and threats of teh selected ice stadiums. Methods: The case analysis was chosen as the main research method. In the preparation of this analysis other methods, such as intentional selection, document analysis and semi-structured interview were applied. Based on the results the SWOT analysis was developed. Through this method the strengths, weaknesses, opportunities and threats of the selected ice stadiums. SLEPT analysis was used to recognize factors, that affects selected ice stadiums. Results: The analysis shows that every single ice stadium is able to assure enough clients. Some cooperate with nearby schools, others are linked with ice hockey club. Three of selected ice stadiums are able to make profit, two are able not to lose money and two were not willing to provide their econimic information. It was also recognized, that there is a huge need to reconstruct some parts in almost every single ice stadium. We could also see that it is important to reach some money from grants. Key words: Ice stadium, ice-rink, cooling, services, document analysis, semi-structured...

Analysis of the ice hockey stadium in Mělník and the proposal of marketing plan
Krejsa, Jiří ; Flemr, Libor (advisor) ; Voráček, Josef (referee)
Title: Analysis of the ice hockey stadium in Mělník and the proposal of marketing plan Objectives: The aim of this work is to elaborate analyzes of the state of the ice hockey stadium in Melnik and to create a proposal of a marketing plan for the stadium. The plan should serve to a more efficient functioning of the entire ice rink in the following years. Methods: The work analyzes years 2011-2013 where it focuses on the utilization of the ice surface, public skating hours and skating schools and analysis revenues and expenditures in the same period. Interviewing visitors, and competitive analysis of stadiums around Melnik were carried out. All values obtained from analyzes were subsequently compared with the national average values obtained from KPMG research. Results: The analyses identified the potential in greater efficiency of utilization of the ice surface and rental of advertising space. When comparing public financing is Melnik's stadium to the national average in the same size cities it turns out that Melnik's stadium is underfunded. The whole proposal of the marketing plan was compiled into 4 main sections aimed at attracting potential sponsors, increased use of ice rinks in the months of September to March, an increase in attendance of public skating and skating schools in the same...

Absorption of ammonia from an operational accident in the ice stadium
Ryšková, Marie ; Gal, Pavel (referee) ; Jecha, David (advisor)
This thesis deals with ammonia absorption in case of cooling machine breakdown at ice pool. Thesis is divided into four chapters. Theoretical part is focused on different methods of cooling an ice rink inside a stadium. Two basic principles are mentioned, how ice rink is created and what refrigerant is used. In the next part are listed valid standards, according to which the operators of ice pools proceed or may proceed to ensure technical safety. Essentials of emergency plan and breakdown preventions are also mentioned. Primary theoretical part focuses on gas cleansing by absorption and its basic principle, which includes Fick's first law, following with introduction to different kinds of absorption machines and its principles. Last chapter is a practical one, in which is the elimination of leaked ammonia by ventilation method and more ecological way – ventilation method with absorber. This cleansing method issue is dealt with mathematically by calculating absorbed gas to liquid using software MathCad.

The urgent and follow-up precautions in case release of ammonia - back analysis of past cases
CHOCOVÁ, Lenka
For this final paper, I chose a rather serious topic that is very topical in our society. Hazardous chemical substance ? ammonia ? is used very widely at present. Ammonia is used as a coolant in various plants. I have compiled a list of all plants in South Bohemia that work with ammonia, including ice rinks. I characterized the properties of ammonia, what damage it causes to the human organism and the environment. I noted a list of accidents during which there have been ammonia leakages of ammonia and I analyzed one accident using a software programme called TerEx. I chose the building of the ice rink in České Budějovice for my research. The objective was to determine the amount of ammonia and to simulate, using the TerEx software programme, an accident with a potential ammonia leakage from the ice rink. I also listed all the activities of the individual components of the Integrated Rescue System, which would help during such an accident, as well as urgent and follow-up measures that would be used. Having assessed the results I came to the conclusion that ammonia leakage from the ice rink would have serious impacts on the residents of České Budějovice. Finally I explained what the terms of evacuation and individual protection mean for the people lining around the ice rink.

Emergency action plan in case of accident with ammonia leak at the Winter Stadium Kotlina Havlíčkův Brod
ZEZULOVÁ, Jana
The amount of ammonia used for cooling stadiums is usually lower than the limits stated in annex to the Act about prevention of fatal accidents caused by dangerous chemical substances, and for this reason the stadiums aren't subject to such strict security procedures determined by the law. However, these are places where big amounts of people can gather in a certain moment, thus in case of accident and ammonia leak, the health condition of many people could be threatened, given the fact that some of them don't even realise how to behave in such a situation. In the introduction of my thesis I focused my attention on the issues of extraordinary events, dangerous substances and products, on the legislation concerning the sphere of chemical substances and protection of population and accidents associated with the spills of dangerous substances. My work also contains the characteristics and description of ammonia and computer programmes used for modelling of consequences of accidents associated with spills of dangerous chemical substances. In the practical part of my thesis I simulated an accident with ammonia leak from Winter Stadium Kotlina in Havlíčkův Brod using the programming tool TerEx and from the results that I obtained I suggested a ?emergency action plan" targeting the analysis of eventual evacuation of pupils and pedagogical staff from the neighbouring primary schools. I used interviews with headmasters of primary schools for the purposes of this analysis. Furthermore, I analysed the population's level of awareness and knowledge of the problem (people living in the area of simulated zone of danger) and pedagogical staff from the neighbouring primary schools in the issues of correct practice in case of ammonia leak from the winter stadium. A part of thesis is a leaflet warning processed and an information poster intended for the population living in Havlíčkův Brod about correct practice in case of release of hazardous chemicals.

Protection of populatin in the immediate environment of icestadiums.
HAVLIS, Václav
Ice rinks have become important sport facilities in towns and cities. They are mostly situated in densely populated centres. The ice is made and kept by refrigeration plant placed in the stadium engine room. Refrigerating medium is mostly ammonia which is toxic, irrritating and harmful to the environment. Considering this fact, eventual breakdown of the refrigerating system poses a risk for people in the surroundings. The work is particularly aimed at preparing an instruction manual for integrated emmergency system and state authorities to upgrade their theoretical and practical knowledge and to be used as a supportive material when dealing with refrigerating system breakdown and consequent ammonia release. A technique used in the Bachelor´s work was a model breakdown demonstration of the ice rink in Jindřichův Hradec. Then all the data obtained were evaluated by the TerEx programme and finally relevant steps and measures were suggested. The findings revealed the fact that the attention is mostly paid to response recommendations in the breakdown centre while the surroundings are not involved sufficiently. The manual application together with upgrading material equipment may significantly reduce the negative effect of the breakdown on the ice rink surroundings and, especially, on civilians.

Duties and action against amonia-escape from fixed object
UBLANSKÁ, Silvie
The objective of my thesis was to compare ice stadiums with respect to protection and security of ammonia management and possible consequences after the release of ammonia into the air. I also wanted to examine if the awareness of residents living in the vicinity of those facilities is satisfactory and to suggest preventive measures which would diminish the ammonia action in the event of its release.
