Competitiveness of the Czech work force
Reinoso, Filip ; Zadražilová, Dana (advisor) ; Chylíková, Hana (referee)
Důležitost lidského faktoru v rámci globální soutěže o zdroje ekonomického růstu neustále roste. To je zapříčiněno nejen stárnutím populace ve vyspělých zemích, ale i nedostatkem kvalifikované pracovní síly. Na základě komparativní anylýzy provedené v této práci bylo zjištěno, že největším problémem české pracovní síly je nedostatek kvalifikovaných pracovníků. To je zapříčiněno nízkým podílem vysokoškolsky vzdělaných obyvatel ve srovnání s ostatními zeměmi Evropské unie. Chce-li si Česká republika zajistit konkurenceschopnost musí více investovat do lidského kapitálu.

Evaluation of elastic parameters for models of isolated cells
Krbálek, Jaroslav ; Fuis, Vladimír (referee) ; Burša, Jiří (advisor)
This diploma thesis focuses on computational modeling of the cell mechanical tests. The goal of this thesis is to build a cell model and to simulate compression test on this model. If necessary, the model should be adjusted so the model reflects real cell behavior. It was created the cell model reflecting cytoplasm, nucleus, membrane and cell cytoskeleton. Cytoskeleton was modeled as tensegrity structure. After this, the pressure test was simulated on this model. The behavior of the cell model and real cell was compared using the stress force. The stress force - cell deformation curve was markedly different for the cell model and the real cell. For this reason, the cytoplasm material model was adjusted. The difference between the curves was acceptable after this modification. It was found during computations that the cytoskeleton model influence on the cell load is minimal. These results does not reflects real cell behavior, which means that the model is considered inadequate for performing stress load simulation.

Computational analysis of the dynamic behavior of the thrust bearings
Žatko, Miroslav ; Kos, Pavel (referee) ; Malenovský, Eduard (advisor)
This master´s thesis solves the problem of stationary viscous flow of incompressible fluids in thin layers of fluid film lubrication in fixed pad thrust bearings. The parametric computational model of oil domain was created for investigation the distribution of pressure, velocity and thermal fields together with the determination of the basic parameters as axial force, heating up and friction loss. Subsequently this model was applied for investigation influence of uneven bearing clearance. The problem task was solved by final volume method in Ansys CFX 12.0 software.

Specifics of Marketing Communication Targeted on Seniors and Unfair Practices Against Them
Nováková, Vendula ; Průša, Přemysl (advisor) ; Pudil, Jiří (referee)
This master thesis "Specifics of Marketing Communication Targeted on Seniors and Unfair Practices Against Them" aims to familiarize the reader with the ways and coercive methods by which traders force seniors to buy overpriced goods or services during the selling events or doorstep sales. Another aim is to identify the reasons that lead elderly to attend sales events, or use the services of door-to-door seller. Next, I will try to make recommendations to public authorities and elderly how to prevent unfair trade practices. The thesis also deals with legal regulations, the demographic situation and development, and manipulation.

Current problems concerning administration of uninsurable allowances at regional (district and municipal) office
Paikrová, Yvonna ; Tomeš, Igor (advisor) ; Víšek, Petr (referee)
The basic mission o f the state is to create the conditions for the stability and to regulate the social climate, to absorb the social tension and by the development o f social activities to stabilise the situation in the society in order to enable the social subjects fully develop, affect and realise their targets by their own forces. These efforts intend to establish the conditions for the social defensibility of the social reform and/or minimize its impacts. In order to assure this target, the state disposes by the wide system of legal, financial and institutional instruments. The aim o f this thesis is the global evaluation of the actual legislation on the security of the people in socially indisposed situation; this people enters under the application of the Act No 117/1995 Coll., on social state aid, Act No 108/2006, on social services, Act. No 110/2006 Coll. about the existential minimum and Act No 111/2006 Coll. on aid in material necessity. When I evaluated the practical problems with the realisation of these systems I have resulted from the experience o f the employees of the Employment office in Tábor and of the Department o f social affairs and public health o f the Office o f region South Bohemia. The state social aid is the integral part of the social state policy. The benefits of the state...

Evaluation of State Employment Policy in the Countryside Prachaticko
ZÁHORKOVÁ, Adéla
The region of Prachaticko belongs without doubts, with its small density of population and absence of big centres, to countryside regions. Changes after November 1989 caused essential turn in structure of employment on countryside. Huge amount of inhabitants was released from agricultural production and they remained unemployed. At the same time there was not expected restoration of family farms, which were supposed to continue with tradition of Czech agricultural production. On the countryside also arose a question about investors, who had no interest to invest there, which caused another absence of working positions. Major part of countryside inhabitants is now forced to travel to work to the cities every day. These and another factors often decreases chances of countryside inhabitants to gain a job (opposite to inhabitants of cities) which could cause to the countryside inhabitants impression, that they are somehow handicapped on the labour market. The state should (as part of employment policy) accept targeted steps against issue of increasing unemployment and the countryside should have been one of the places, where these steps should have been realised with priority. In theoretical part of my bachelor Thesis I define actual state of problematic of unemployment on the Prachatice countryside. For the collection of data was used quantitative research in form of questionnaire research. Secondary was analysis of data and half-structured dialogues with people interested in the issue. The goal of questionnaire research was confirmation following hypotheses: Unemployed town people from Prachaticko region are more satisfied with state employment policy than unemployed inhabitants of Prachaticko region. Bigger dissatisfaction with state employment policy was proved within unemployed countryside inhabitants of Prachatice by 3 of 5 questions. However differences between both groups are not very big and none of the question ended with conclusive result. Secondary analysis of data showed, that the most problematic area by the point of view of unemployment is on south-east of region. There are also minor amount of working positions on the Prachaticko countryside than in the regional towns. In the context of average amount of unemployed people in Czech Republic is Prachatice region in relatively good position, but against town areas of Prachaticko region is Prachaticko countryside without doubts handicapped. Respondents most commonly think that interventions of state policy lead to the decreasing of unemployment, but not sufficiently.

Ion attachment and ion emission of dust grains
Vyšinka, Marek ; Němeček, Zdeněk (advisor) ; Wild, Jan (referee)
Small dust grains could be found in many environments. Because of their size, their charge and the electric forces acting on them play an important role in their dynamics. The dust grain charge is influenced by many different processes. Among other methods, charging processes can be studied by trapping a single dust grain inside an electrodynamic quadrupole where it is put into specific environment (ion or electron beam, UV radiation). The progress of the charging process can be inferred from the changes in the grain charge. Our work contributed to the building of a new laboratory set-up for study of the charging processes. Specifically, a new Faraday cup for measurements and stabilization of the ion and electron gun currents is designed and its function verified. It solves the shortcomings of the previously used Faraday cups. Further, an amplifier for the ion gun current measurement is designed and constructed along with the design of digital stabilization of the current. The stabilization is neccesary for the interpretation of measurement results and its digitalization will allow more flexible adjustment and easier connection with the control computer. Finally, data acquired during the charging of dust grain with different ion species are evaluated in order to study the effect of different ions on surface...
