Selected data mining methods and their applicability to the television audience monitoring data in the Czech Republic
Walter, Jan ; Hájek, Petr (advisor) ; Jirků, Petr (referee)
Data mining is nowadays a fast-growing field, which incorporates machine learning, statistics, and logic within computer science. It has the potential to bring new insights into almost all branches of human activity, because the data are stored almost everywhere. This thesis tries to show the main aspects of the original Czech method Guha, to demonstrate its strength via its application to television audience data, and finally to compare it with the association rules method, which is similar to it. The ambition of this text is to interconnect the world of praxis with the theoretical field, where methods are invented. It also serves as an introduction to data mining itself. The results show that Guha is a full-value method with several interesting features and might be a good tool for extracting knowledge from analyzed data.

Role of the WTO in economic progress of developing countries
Walter, Jan ; Adamcová, Lenka (advisor) ; Dubský, Zbyněk (referee)
Underdevelopment of developing countries is in present one of the thorniest problems of the world. Economic globalisation brings about increasingly deeper integration of world markets and increasing volumes of international trade. Multilateral trading system represented by the World Trade Organization (WTO) is one of the instruments that can, under certain circumstances, strongly contribute to economic progress of developing countries. The goal of the thesis is to reveal such circumstances and describe their coherence with the WTO and its predecessor the General Agreement on Tariffs and Trade. Firstly, the thesis focuses on theoretical basis of international trade as an instrument of economic development. The thesis also describes possible imperfections of the theory specifically with regard to developing countries. Secondly, the role of the WTO in the process of liberalisation of international trade and its activities leading to reduction or elimination of the imperfections are described. The thesis shows that, on the known theoretical basis, it is possible for developing countries to gain from liberalisation of international trade on the multilateral basis. The thesis, however, also indicates that it is possible to achieve certain improvements in the existing system to the benefit of the developing countries and leading to their greater and more equitable involvement in the international division of labour.
