Outsourcing and its impacts on company through Enterprise architecture
Štěpán, Jakub ; Šebesta, Michal (advisor) ; Bruckner, Tomáš (referee)
This final thesis is dealing with the theme of outsourcing and its influence on company in connection with enterprise architecture as the main carrier of ongoing changes. Main focus of this thesis is to provide the overview of the area of Enterprise architecture and outsourcing as well as the description of the selected notation of Enterprise architecture modeling, which will be main instrument in describing the transformation. Theoretical part of the work is divided into three parts. Firstly there is description of the enterprise architecture and chosen connected areas, followed by description of the outsourcing process and description of the modeling language ArchiMate. Practical part of the work is composed of analysis, description and evaluation of the transformation of the selected company. Among the main contribution of this thesis there is description of the changes during the transformation using the ArchiMate modeling language and identifying of concrete impacts of outsourcing on Enterprise architecture of the company.

Information systems security penetration testing
Klíma, Tomáš ; Doucek, Petr (advisor) ; Čermák, Igor (referee) ; Čapek, Jan (referee) ; Štubňa, Ivan (referee)
The aim of this dissertation thesis is to develop new methodology of information systems penetration testing based on analysis of current methodologies and the role of penetration tests in context of IS/IT governance. Integral part of this aim is evaluation of the methodology. The first part of the thesis is devoted to the presentation of history and current state of research in selected area, definiton of basic terms and introduction of role of the penetration tests. This part is followed by the review of relevant sources and comparative study of current methodologies with a goal to identify their weaknesses. Results from this study are further used as a basis for new methodology development. Classification of IS penetration tests types and testing scenarios are also included. The second part includes design of new methodology, at first its history, structure and principles are presented, then its framework is decribed in high level of detail. In the third part the reader can find (theoretical and practical) validation. The biggest scientific contribution is the methodology itself focused on managment of penetration tests (which is the area currently not sufficiently descibed). Secondary contribution is the extensive review and the comparative analysis of current methodologies. Contribution to the economic and technical (practical) application we can mainly see in the development of new methodology which enables companies to improve management of penetration tests (especially planning, operational management and implementation of countermeasures).

Výběr a implementace open source nástroje pro řízení portfolia projektů
Marek, Jan ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
Methods and ways of implementation of changes and innovations in companies through project management are in today's society very well established. There exists methodologies, techniques and tools for the management of individual projects. However in a role of project manager, I very often faced the fact that companies are performing the project portfolio management in very intuitive way. This in itself leads to failed and prematurely terminated projects, initiation of the wrong projects or realisation of correct projects, but at the wrong time. Very often I have also recognized, that there is lack of awareness of fact, that there are also Open Source applications that can help with the organization's portfolio. This thesis deals with the definition of requirements, search and selection of proper OSS application and subsequent implementation. In the first part of this thesis I prepare a theoretical framework about PPM, and on that basis then identify and verify a set of requirements for selection of right OSS PPM application. The next section of thesis describes searching for suitable applications from a variety of sources, assessment against the requirements and the final selection. In the last part the implementation project is drafted, which aims to serve other colleagues in project management as one of the possible implementation paths. The outputs are then continuously confronted with experts in matter of projects and project management in the field of IT in order to maximize symbiosis between theory and real life experiences. Virtually every project management methodology defines the collection of already-proven techniques, best practices or lessons learned from the previous similar implementations. The main contribution of this thesis I see in fact that it contains not only the design of the project implementation, but also describes a logical path, what leads to the result. Therefore this thesis could be used as a base or discussed best practice, when a project of implementation of PPM application in place.

Depositary Services
Helcl, Tomáš ; Janda, Karel (advisor) ; Veselá, Jitka (referee)
The thesis deals with the functioning of depositories in the enviroment of the Czech market from the perspective of legislative and practical. The introduction is devoted to directives that make up a harmonized legal framework and the Czech legislativ, which specifically prescribes behaving of depositories. The main part is devoted to the depositary functions, such as operating in the Czech market conditions. This part of work is focused not only on the distribution of the depositary market, but also on the collected amount of the fees, the efficiency of regulation in the real market enviroment and in the importace of depositories in the Czech market. The final section is devoted to the findings, including the final assessment of the depositaries. As a first of its kind, this thesis gives a comprehensive view of activity of depositories and their importace for the Czech market, as the depositaries represent entities that control whether funds act in accordance with the legislation. Depository oversees as to prevent fraud and to qualified investors or collective investment contributed to the further development of the capital market, which is necessary for the further development of all economic sectors.

Micro-electromembrane extraction across multiple aqueous and organic phases for selective pretreatment of raw biological samples
Kubáň, Pavel ; Boček, Petr ; Seip, K. F. ; Gjelstad, A. ; Pedersen-Bjergaard, S.
Micro-electromembrane extraction (μ-EME) across multiple aqueous and organic\nsolutions was developed for selective extractions of various analytes from untreated\nbiological samples. The novel approach requires μL volumes of samples and organic\nsolvents, which form consecutive immiscible plugs in a transparent polymeric capillary\nand the extraction process is accelerated by application of d.c. voltage. Number of the\nplugs, their composition, volume and sequence in the extraction capillary can be chosen\nspecifically for each particular application and high variability and selectivity of the\nextraction process can be achieved. In this contribution, we demonstrate suitability of\na five-phase μ-EME system for simultaneous extractions of cations and anions from\nurine and for selective extractions of basic analytes based on their acid-base strength\nfrom plasma.

Permeation of VOC vapours through carbon nanotube network membranes controlled electrically
Slobodian, P. ; Říha, Pavel ; Olejník, R.
In this letter, we report the increase of permeation rates of some typical volatile organic compounds through entangled carbon nanotube networks by an electric current. The change in the permeation rate is reversible when the\ncurrent is turned off. The permeation rise is partly probably due to Joule effect and thus increased membrane temperature and vapor pressure in the vicinity of the inlet side of membrane. However, the effects of vapor polarity and electrostatic interaction of vapors and charged nanotubes seem to be also involved and contribute to the differentiation between alcohol and carbohydrate vapors permeation.

The tax system reduces motivation to return to work among mothers with young children: recommendations and evaluation
Šatava, Jiří
In the Czech Republic, the overall taxation of work, i.e individuals' income tax together with social security and health insurance contributions, places a heavy burden even on the relatively low earnings of so-called second earners in households, i.e. partners with lower earnings. These peoples' work activity is, however, generally very sensitive to the level of taxation. A large group of these earners is made up of mothers with young children. Mothers who are the second earner in their household are subject to a participation tax rate (PTR) up to 30 % higher than their partners, and yet a higher PTR results in lower motivation to work. Women with children and low earning potential are subjected to the highest PTRs in comparison with their partners.

The Tax Assignation and Theater
Gerneš, David ; POKORNÝ, Jiří (advisor) ; VÁVROVÁ, Hana (referee)
Bachelor thesis aims based on an analysis support system theaters in the Czech Republic, the analysis of the tax system in the Czech Republic and analysis of tax assignations in the Slovak Republic, to investigate whether for the Czech theater network, this measure was beneficial and whether it would be worth it to deal with its introduction into practice. The thesis also examines the impact of the introduction of the assignation of income tax on Czech public budgets and polls. Within the survey sent to 120 respondents who were asked about their relationship to culture and whether they would be introducing a possibility for assignations and what area non-profit sector would contribute. On the basis of these steps is then designed a system of assignations suitable for Czech Republic.

The Media Influence on Transformation of Democracy
Půlpánová, Barbora ; Pehe, Jiří (advisor) ; Slačálek, Ondřej (referee)
Mass media has always played the key role in democratic process. They are not only the indicator of its right functioning, but also the iniciator. From historical point of view is obvious, that technological progress and changes in the way of informing people were related to the political area. But with the increasing role of media, they changed their position from pure mediators of informations to the main actors of social and political life. The ‚old' media, such as newspapers, radio and television, are therefore partly responsible for commercialization of the public sphere and also for its depolitization. With contribution of the globalization effect on today's world, which causes besides other things the weakening of the nation state, there are only a little of the key democratic aspects left. Some find the solution in the ‚new' media represented by the Internet and social media, which are more interactive so they could get the citizens back to the game. And right in the increase of civic engagement see the theorists the potencial for creating a new democratic order based on high-level participation. KEY WORDS Mass media, Democracy, Public Sphere, Civic Engagement, Internet, Social media, Participative Democracy, Deliberative Democracy
