Acoustics of small fans
Hájková, Lenka ; Rubina, Aleš (referee) ; Cifrinec, Ivan (referee) ; Hirš, Jiří (advisor)
Dissertation thesis falls within area of indoor climate and deals with investigation of acoustic microclimate in sanitary rooms of residential buildings during a mechanical ventilation. Sources of a noise in these areas are small fans. The thesis contains the evaluation of the existing situation concerning the referred issue, physical laws of acoustics and theoretical basics of acoustics of air conditioning. The part of the thesis is experimental measurement which aims to evaluate the situation in real applications and the possibility of influencing the acoustic microclimate by affixing of small fans on the building structure. The work contains a model for the verification of certain anticipated dependencies and theoretical investigation of the distribution of sound pressure levels in the sanitary room, depending on the location of the noise source. The last part of the work offers possible measures to improve the acoustic microclimate and elimination of the noise in sanitary rooms and in protected areas of residential buildings.

Quality of living of children and adolescents in a children's home
Hájková, Lucie ; Nová, Monika (advisor) ; Ondrušová, Jiřina (referee)
This thesis focuses on the quality of life of children and young people in a children's home. The aim of the thesis is to describe the lives of children in the observed children's home and to compare possible changes and development since their placement to the present. This description and comparison were made through the case studies of two selected boys. To supplement the information and strengthen this topic, an interview was conducted with the host. The thesis is divided into a theoretical and empirical part. The theoretical part consists of several chapters that are subsequently related to the practical part. Here, I mention the history and current state of children's homes in the Czech Republic, types of children's homes, causes of children's placement in children's homes, children's needs, and developmental stages of children. In the last chapter, the literature review describes the CAN syndrome. The empirical part is focused on qualitative research methods. The research was conducted by observing and getting to know the operation and schedule of the home, its staff, and the children themselves. For the research, case studies were developed based on the mentioned documents, files, and internal records. To better grasp and deepen the topic, an interview with the host was conducted. The...

Vybrané vlivy působící na tržní produkci klisního mléka
Hájková, Lucie
This bachelor's work is focused on selected influences which have impact to the market production mare's milk. Work consists of two parts. First part is theoretic. This part is focused on composition of mare's milk. Within this part there was made mare's milk sampling and analysis. This milk was milked from breed Hafling. This part includes also influences which impact market production mare's milk. Monitored effects were order of lactation, feeding dose, season and breed. Second part deals with own proposal of the farm construction with mare's milk production. This part describes buildings which will be part of farm, especially stalls for breeding animals, milking house for mare's milk production and other buildings which will be used within riding club. Further there is characterized livestock which will be breed at the farm with focus on its breed. At the end the offered services and price list of this service are described. Within proposal there were carried out survey in the village Drnovice. Twenty-one families with children were interviewed. Interest in mare's milk and products made of this milk was evaluated on the base of this questionnaire.

The readiness of chosen kindergartens in the emergency planning zone of the Temelín Nuclear Power Plant
HÁJKOVÁ, Lucie
The thesis is based on the assessment of the readiness of staff in selected kindergartens in the emergency planning zone of the Temelín Nuclear Power Plant. Kindergartens associate a large number of young children who are dependent on the help of adults. Even in the event of a radiation accident, children will not be able to take care of themselves and will clearly be dependent on the help of teachers. For this reason the readiness of staff of this type of school facility in the emergency planning zone should not be underestimated. The aim of the thesis was to analyze the knowledge of staff in selected kindergartens (Dříteň, Zliv, Albrechtice nad Vltavou, Neznašov) in the emergency planning zone of the Temelín Nuclear Power Plant. For this purpose was established a hypothesis: "The knowledge of the staff of selected kindergartens in the emergency planning zone of the Temelín Nuclear Power Plant will be higher than 60 %." To achieve the set goal and to verify the hypothesis a questionnaire survey was conducted using a developed questionnaire. The questionnaire contained 19 questions, and total 55 respondents took part in the questionnaire. Then were the results evaluated using methods of descriptive and mathematical statistics. The hypothesis was confirmed that the knowledge of the staff of selected kindergartens is higher than 60 %. The arithmetic average of staff knowledge in selected kindergartens in the emergency planning zone of the Temelín Nuclear Power Plant was 61.47 %. I consider the current state of knowledge of staff in selected kindergartens to be sufficient, but the results showed insufficient knowledge in the areas of improvised body protection and iodine prophylaxis.

Modelling the onset of phenological phases of spring barley (Hordeum vulgare L.)
Dížková, Petra ; Bartošová, Lenka ; Hájková, L. ; Balek, Jan ; Bláhová, Monika ; Bohuslav, Jakub ; Pohanková, Eva ; Trnka, Miroslav ; Žalud, Zdeněk
The onset of phenological phases of plant species is influenced mainly by air temperature. Each phenophase has its temperature limits (base temperature and temperature sum), which must be reached for each phase to occur. With knowledge of these limits, it is possible to predict the onset of phenological phases in localities where only meteorological data are available and also in future climate conditions. In this work, we used phenological ground-based data from 33 stations within the Czech Republic to calculate the most relevant meteorological predictors. PhenoClim software was used for phenological and meteorological data calibration and modelling. The smallest error that allows us to predict the term of the phenophases was found for the heading of spring barley (Hordeum vulgare L.), as the best predictor was the maximum daily temperature and the statistical error was 3.6 days.

Trnka, Miroslav ; Kudláčková, Lucie ; Čermák, P. ; Balek, Jan ; Novotný, Jan ; Homolová, Lucie ; Semerádová, Daniela ; Brovkina, Olga ; Štěpánek, Petr ; Zahradníček, Pavel ; Skalák, Petr ; Bláhová, Monika ; Benáček, Patrik ; Fischer, Milan ; Sedlák, Pavel ; Janouš, Dalibor ; Žalud, Zdeněk ; Marek, Michal V. ; Možný, M. ; Hájková, L. ; Chuchma, F. ; Knozová, G. ; Beranová, J. ; Zatloukal, V. ; Albert, J. ; Mašková, R. ; Cienciala, E. ; Vizina, A. ; Nesládková, M. ; Melišová, E. ; Hanel, M.
The methodology formulates a procedure for assessing the risks of the occurrence and spread of natural fires in the immediate vicinity of surface sources of drinking water. The methodology\nproposes methods for estimating the consequences of natural fires on surface water quality, forecasting the change in the risk of fires due to climate change and the procedure for determining the risk of secondary pollution of reservoirs due to changes in run off after a natural fire. On this basis, the methodology proposes and diversifies preventíve and operational measures.The measures were designed in connection to modeling results for the Hadce pilot síte near the Švihov reservoir and the experience with the adverse effects of extensive deforestation on the water quality in the Vranov and Vír reservoirs.

Karel Michal - the author of the "popular" literature?
Břenková, Hana ; Hájková, Ladislava (advisor) ; Holý, Jiří (referee)
Na předcházejících stránkách jsem se zabývala tvorbou a životem Karla Michala, pokusila jsem se postihnout stěžejní myšlenky jeho děl. Nyní bych ještě závěrem zmínila několik slov o autorově osobnosti a jeho přínosu literatuře. Od Michalovy smrti uplynulo již třiadvacet let. Jeho jméno je pro mnoho lidí stále neznámé. Ve své době byl ale významnou literární osobností, která vnesla do literatury mnoho podnětného. Již na počátku bylo zmíněno, že Karel Michal ve své tvorbě vystřídal několik žánrů. V každém svém díle však přispěl literatuře něčím novým, obohatil svými povídkami žánry, které stály na jejím okraji, a otevřel nové možnosti dalším autorům, kteří se ubírali stejnou cestou.
