Ščepko, Richard ; Kacálek, Jan (referee) ; Polívka, Michal (advisor)
The bachelor thesis deals with the topic of the security of computer networks. The tasks of the bachelor thesis are the attacks on active network elements with the aim of the catching of data between two users. In the created structure with a stellate topology, the user stations have connect to the active element (switch). In the thesis, the individual ways of attacks and the significance of ARP proceedings to MAC addresses have describ. Several programmes have use in order to take control over the device. Due to a big amount of these active elements the source code of the programmes had to be alter. The work with the programmes ARPtool and ARPoison demanded the operational system Linux, in our case the distribution of Ubunt. The programme WinArpAttacker could be set off under the system Windows XP as well. The achieved results and the description of the practical part are discuss in detail in the summary of the thesis.

The goal of this thesis is to design and develop a framework for building modern single- page application in the JavaScript programming language and describe this approach to development. The work also contains the documentation for a more comfortable use and customization. The content is divided into eight chapters. The introduction is followed by the retrieval of information resources, including the specifics of the JavaScript programming language and explanation of the formation of single-page application. The description of the basic principles of their functioning, motivation and justification, when and why this approach is appropriate is also included. The work is primarily focused on the issue of single-page application, for which the use of the JavaScript programming language is crucial. For this reason, this work provides a whole chapter about this programming language, also including a description of its history and role in the context of others. Below are the common characteristics of single-page applications frameworks, built on top of the library ReactJS, whose formation is engaged in the following chapter. The developed framework also contains the user guide. The practical outcome of this work is an open source framework for creating serverless single-page applications, which is due to its architecture and documentation appropriately adaptable.

Multicriteria games
Tichá, Michaela ; Dlouhý, Martin (advisor) ; Lachout, Petr (referee) ; Čičková, Zuzana (referee)
Theory of multicriteria games is a special field of game theory, when one or more players have at least two payoff functions and want to maximize simultaneously. The work introduces a number of new findings. It examined the concept of finding equilibria in pure strategies in noncooperative multicriteria game. It is possible to find all the equilibria in pure strategies by full search and solving two linear programs for each point. Furthermore, two linear programs are formulated for verifying that a selected point is the equilibrium of the game or not. In the noncooperative games is also introduced the concept that with knowledge of the equilibrium of bimatrix game determines preferences of the players. Although finding the equilibrium point of the bimatrix game is nonlinear problem, finding the preferences is linear problem. The latest findings in the noncooperative games is a generalization of the concept that solves multicriteria game by assigning weights to each criterion of each player. The work demonstrates that it may not be necessarily linear weights, but it can be more general function that describes the player's preference. The remaining part is devoted to knowledge in cooperative games. There is considered that the players know their preferences and are able to express them by weights. The game with known preferences is defined and solved with the use of bargaining theory. Then it is generalized to a case where players have more payoff functions, from which they can choose. Finally, the multicriteria case of voting game is defined. It is designed completely new concept, which selects the winning coalition in the voting game. This concept is then applied to the real situation after the elections to the Chamber of Deputies in 2013.

Support for Unemployed People Aged Under 30 Years at Entry to the Labor Market
ŠABARTOVÁ, Alžběta
The Bachelor Thesis deals with the problems of unemployment benefits for people at the age up to 30 when entering the employment market. Unemployment is currently one of the serious problems in the world. The reduction in the number of unemployed people is one of the political priorities. The meaning of work as a job is taking an irreplaceable position for the life within our culture. Job loss has a considerable influence on social as well as personal life of an individual. The age is playing a significant role when seeking a job. Especially the time connected with the beginning of the career. School leavers who apply for their first job are concerned. They have no working experience, no practice, and they have so far had no possibility to acquire the basic work habits. A disharmony between zero experience and excessive earnings demands belongs to other root causes of the lack of interest in giving work opportunity to school leavers. Employment Office plays an irreplaceable role for the mediation of job and the consultancy. To solve unemployment within each target group, active and passive labour policies are available. The situation of the specific target group is stimulated especially through single programs and projects. The theoretical part pays attention to the definition and objectification of the unemployment-related terms and the analysis of labour market in Ceske Budejovice. Observations of a number of authors who are dealing with these problems and the related issues are summarized herein. The empirical part is formed by observations from own investigation. Two job-related targets have been set. The first target is to analyse the ideas the young people aged up to thirty, living in the district of Ceske Budejovice, have of their employment. The other target is to analyse the employers´ ideas of giving work to school leavers and young people. In order to fulfil the above targets, two investigative questions have been put: 1: Young peoples´ ideas of earning possibilities are unrealistic. 2: Employers find the European Social Fund helpful in giving work to young people. For the purpose of answering the investigative questions a qualitative research method, namely a case study the study of a few cases was selected. Interviewing was chosen as the most suitable method of data gathering. Initially, ten participants aged up to thirty were interviewed. At the time of interviewing, all of the participants were registered at the Employment Office in Ceske Budejovice and were taking part in a retraining scheme arranged by the Employment Office. When talking with young people I found that their gross commencing salary is expected to amount to approx. 16 200 CZK. The other selective group comprised five employers in Ceske Budejovice. It emerged from the interviews that one of the companies does not utilize the programs and projects announced by the European Social Fund at all. Two of the companies complain about excessive administration. One of the employers must always carefully consider its ability to satisfy the involvement conditions. Some negative feelings also appeared about the frequent changing the blank forms, a low number of announced projects for a particular business branch. The programs being related to deepening knowledge and staff training were most appreciated. The results of the Thesis will give the Employment Office a feedback on the utilization of the European Social Fund by employers and will help in adjusting the conditions for further projects being prepared.

Cooperation of high schools with external contractors in preparing school educational programs
Tulach, David ; Lačev, Alek (advisor) ; Hochel, Matej (referee)
This thesis, Cooperation of high schools with external contractors in preparing school educational programs, deals with the question whether it would be possible and beneficial for high schools to cooperate with companies on the preparation or modification of their educational programs, with the goal of improving the quality of education. After initial contributions from experts who provided negative replies to this question, the view was focused on the root of the issue - what are the historical pillars of public schools and pedagogy, what does science say about learning and teaching, how pedagogy reacts to the crisis of science. After comparing literal sources and results from interview with the experts, in combination with a trace and activity analysis, a theory was established that public education is reaching a point of crisis, has not changed in its essence since its beginning and that the best solution might be the establishment of alternative educational institutions.
