Risk in Costruction Industry: The Management and Financial Impact
Štěpánková, Vladěna ; Půža, Bedřich (referee) ; Smolík, Otakar (referee) ; Suchánek, Petr (referee) ; Režňáková, Mária (advisor)
The present dissertation studies financial impacts of risks in the construction industry, providing one of possible ways of the risks expression and monitoring, through which they can be efficiently managed. Theoretical assumptions and selected methodology provided basis for an overall analysis of the Czech Republic construction market, identifying possible external risks sources including their processing and description. The present dissertation aims at finding major risks and assessing their financial impacts that pose threats to companies active in the construction sector, indeed a specific sector for doing business. These risks have been compiled in a Risk Catalogue intended as a guide for selected risks management. To elaborate on the risks identified, two specific companies have were selected, having provided their data (financial reports, accounts statements, number of projects contracted including their volume and type, personnel information, etc.), as well as key indicators they have been using. The dissertation outcome presents construction sector analysis and Risk Register compilation. The work clearly defines the procedure of the Register compilation, possibly to be used by construction companies with respect to recurrent activities and the risks involved. The Catalogue sorts risks in categories and defines their possible occurrence as well as their financial impact on the company. Furthermore, it presents their possible management, i.e. how they can be minimized or even eliminated, as well as necessary costs involved. Indeed, the costs have to be considered in the sense of financial impacts so that it does not result in covering risks with rather low financial impact.

Study of differential potential of germ stem cells in vitro in higher vertebrates
Smolík, Ondřej ; Krylov, Vladimír (advisor) ; Krulová, Magdaléna (referee)
Spermatogonial stem cells are unipotent male germ cells which provide spermatogenesis during the whole life. In 2004, an important experiment was conducted. During in vitro cultivation mouse spermatogonial stem cells gained the characteristics of embryonic stem cells, pluripotency by all means. Those cells had the feature to spontaneously differentiate into all three germ layers, endoderm, ectoderm and mesoderm. They also could pass its genetic information to the next generation and they could give rise to teratomas. By this event, experiments started on other vertebrates including rodents, domestic animals and also human. Differentiation of these cells can be directed in vitro to generate specific cell types. On base of these facts, spermatogonial stem cells are alternative source of pluripotent cells which possess many applications in life sciences. The purpose of this thesis is to summarize actual knowledge about differentiation potential in vitro of spermatogonial stem cells in higher vertebrates and try to identify tendencies which they prefer during differentiation, if they exist.

Study of chromosomal evolution in Xenopus mellotropicalis
Smolík, Ondřej ; Krylov, Vladimír (advisor) ; Nguyen, Petr (referee)
The evolutionary relationships in Xenopus genus are intensively studied for its interspecific variability and high conservation in evolution. These characteristics possess an opportunity for comparative studying of polyploidization phenomenom on interchromosomal level and an occasion to identify the genome-forming mechanisms with cytogenetic methods. XME chromosomes (X. mellotropicalis, 2n=40) were identified via p-/q- arm length ratio in a comparison with morphometric analysis of X. epitropicalis (2n=40) chromosomes. Whole chromosome painting probes were prepared from X. tropicalis (2n=20) microdissected chromosomes and they were applied to XME metaphase spreads via optimalized Zoo-FISH. 10 chromosomal quartets were detected and one balanced non-reciprocal translocation between chromosomes XME 2 and XME 9 which must have occured in a diploid ancestor. Thus, we disprove the theory of Silurana subgenus origin via only one polyploidizatin event. Powered by TCPDF (www.tcpdf.org)

Chemical weed management in potatoes
Smolík, Ondřej ; Hamouz, Pavel (advisor) ; Holec, Josef (referee)
Presented thesis is focused on the topic of regulation of weeds in potatoes. The advantages and disadvantages of chemical control of weeds are investigated, including the comparison of the results obtained in both herbicidal and mechanical treatments. The core of this thesis is to find out what kind of influence has weeds on potato yield and how is the weed infestation affected be herbicides. The research was undertaken by a field experiment with eight treatments. The first one brought a field completely without any interventions. On the second field a mix of Sencor Liquid (PRE), Command 36 CS (PRE) and Roundup Klasik (PRE) was used. The third treatment was sprayed by Sencor Liquid (PRE), Command 36 CS (PRE) and Pantera QT (POST). The fourth one was treated by both Sencor Liquid (POST) and Titus 25 WG (POST). The fifth treatment obtained only mechanical interventions (machine hoeing). On the sixth one Sencor Liquid (PRE), Command 36 CS (PRE) and Roundup KLASIK (PRE) were applied in combination with the mechanical treatmant. The seventh treatment used Sencor Liquid (PRE), Command 36 CS (PRE) and Pantera QT (POST), again combined with the mechanical treatment. On the last of the experimental fields Sencor Liquid (POST), Titus 25 WG (POST) and a mechanical treatment. Treatments 2-8 were compared to the first one. In this comparison it turned out that the herbicides help on a great scale with the regulation of the weed. By the treatments 2, 3, 6 and 7 the potato yield was three time higher compared to untreated control. Treatments 4 and 8 showed that the application of some post-emergent herbicides can (due to their phytotoxicity) decrease the yield to the level of the untreated plots.

Data Quality, Data intagrity and Data Consolidation in BI
Smolík, Ondřej ; Pour, Jan (advisor) ; Zajíc, Ján (referee)
This thesis fights with the data quality in business intelligence. We present basic principles for building data warehouse to achieve the highest data quality. We also present some data clearing methods as deviation detection or name-address clearing. This work also deals with origin of erroneous data and prevention of their generation. In second part of this thesis we show presented methods and principles on real example of data warehouse and we suggest how to get sales data from our business partners or customers.
