The influence of repeated defrosting on nutritional efficiency of Artemia salina nauplii for early developmental stages of fish
HULAN, Petr
Nutritional efficiency of deeply frosted and repeatedly defrosted zooplankton has not been totally clarified, and it is often questioned, however, the nutrients composition and effect of such deteriorated feed are missing. The aim of this study was to assess nutritional eddiciency of repeatedly defrosted nauplia Artemis salina, as well as changes in their chemical composition on the basis of the growth, survival and presence of the deformations in early ontogeny of Japanese medaka ( Oryzias latipes). The samples of fresh hatched artemia nauplii served as a control group. The experiment was carried out with samples of live nauplii, permanently frosted at -14°C, defrosted to 4°C and again frosted and defrosted to 25°C and frosted again. The larvae of medaka in the period of one week after shift to the exogenous nutrition were examined. Before the commencement of the experiment the composition of samples in terms of nutrient, amino acids and fatty acid contents was determined. The results proved that Oryzias latipes fed with live artemia not only grew better but also survived more that other fis in other treatments. No deformations were recorded Fish fed frozen food survived better than those fed with live Artemia. It was also found that fish fed live Artemia seems to be the highest however from the amino acid point of view it seems to be more appropriate to freeze it to -14°C, defreeze to 25°C and refreezing to -4°C. as for the fatty acids Artemia adjusted by the permanently freezing to -14°C. The processes of thawing and repeated freezing of artemia nauplii result in leaching of some nutrients but in the thickening of some others.

Somnipathy in children
MAŘÍKOVÁ, Linda
This dissertation deals with night insomnia in children. With the growing number of complaints of parents about insomnia in particular in infants and toddlers, this problem becomes very topical and frequently discussed not only among parents themselves but also among the medical workers involved in the child care. No unambiguous cause of why some children sleep well and other children do not has been yet proven. However, experts dealing with these problems present an opinion in the literature that the main cause lies in the incorrect approach of parents to creating sleep habits in their children. They supplement their opinion by a set of recommendations how to avoid or possibly solve the problems by applying the appropriate approach. Our dissertation thus aims at ascertaining how parents' approach affects creating of incorrect sleep habits in infants and toddlers. The other objective consisted in subsequent drawing up of the nursing diagnosis and nursing care plan by means of which the nurses could independently solve the problems related to insomnia in children. A qualitative research based on the contingent valuation method has been carried out. The methods of data collection included the structured interview performed with two small sets of mothers of children. The first set comprised mothers of children with no sleep problems and the second set was composed of mother of children suffering from sleep problems. The prepared questions related in particular to children's sleep habits. Both sets were compared and the data were also subject to the Fisher's exact test. Although it was not possible to prove that inappropriate approach of parents to creating sleep habits in children is the unambiguous cause of the children's sleep problems, we believe that such inappropriate approach is a related factor. This assumption is supported also by the result of the other part of the research, a non-structured interview. This interview from which casuistry was subsequently created was performed by one of the mothers whose child had suffered from sleep problems. The said mother was willing to try to implement the recommended measures and she subsequently described to us how her son's sleep problems attenuated significantly. On the basis of our hypothesis that creation of correct sleep habits might help children suffering from insomnia, despite the fact that no direct relation between the sleep habits of children and their sleep problems has been proven, as the output of this dissertation we have drawn up the above mentioned nursing diagnosis and nursing care plan which could help the nurses independently solve the children's sleep problems. We also believe that it would be appropriate to carry out research in the future dealing with direct evaluation of success or failure of the recommended measures in solving insomnia in infants and toddlers.

Changes in the behavior of children in a group of school clubs the careful application of effective communication
SOLDÁTOVÁ, Jana
The thesis deals with the instrumentality of usage efficient communication and prosocial activities on primary children´s behaviour in class after-school club. The observed areas are coping, solving plus percent occurrence of conflicts, mutual communication together with the expression of personal opinions. Furthermore, the work compared the atmosphere within the class after-school club before the research in January 2014 and after its completion in June 2014. The results of the empirical investigation of quantitative research are compared with each other at the beginning as well as at the end of the research. These outcomes were compared with the results of the control group. They prove that the change of educational approach by using the effective communication and prosocial activities can affect children's behavior.

The capital controls and their impact in the short and long term
Papežík, Ondřej ; Šíma, Ondřej (advisor) ; Pour, Jiří (referee)
The present thesis analyzes the application of capital controls and their impact on the economy in the short and long term. These regulatory measures have gone through many periods and opinions in which they were considered as both positive and negative instrument not only of monetary policy. Global financial crisis of 2008 has again raised a lot of questions dealing with this topic. Capital controls may help ease the acute problems associated with inflows or outflows in the short term but they will not solve the issue of the country's susceptibility to movements of primarily debt capital. Long-term capital closeness (whether in terms of export or import) may causes, inter alia, the excessive accumulation of savings in the domestic closed economy or lack of capital for economic development. Therefore, when applying capital controls it is also necessary to improve the country's institutional quality which proved to be an important determinant of capital flows.
