Řízení IS/ICT se zaměřením na sourcing služeb informačního systému
Šebesta, Michal ; Voříšek, Jiří (advisor) ; Havlíček, Zdeněk (referee) ; Příklenk, Oldřich (referee) ; Král, Jaroslav (referee)
Research on outsourcing has been around for several decades, while recent evolution in the information systems discipline towards ICT service commoditization significantly changes the context of decision-making. Services that are available on-demand via the Internet allow organizations implementing functions they demand in a fraction of time. This trend represents a chance for organizations seeking to use advanced ICT services without a need of major investments. Problem is the current lack of guidelines and tools for managing ICT services and their outsourcing. Given the trends on the ICT service market, it is expected that much of the IT management in the future will encompass the ICT services and utilize service-level structures. Methods currently available are either too broad or encompass only small part of the whole problem. Ad-hoc or unsound decisions in this area might cause major complications in terms of quality, usability, integration, and consequently influence total cost of organizational IT. Organizations need to either revise existing models or propose and implement completely new models to manage their IS/ICT. This thesis deals with the management of IS/ICT with focus on the ICT services outsourcing. It discusses available sourcing models in the literature and links them to the various interconnected areas. Based on these areas, it presents an integrated view on IT outsourcing strategies. Most importantly the thesis proposes an original concept for decision-making about outsourcing of ICT services named the SOURCER framework. This approach utilizes the presented outsourcing strategies, and introduces a complex methodology and decision-making criteria that will assist organizations with selection of ICT services in order to maintain and manage a most suitable ICT service portfolio. The decision-making is based on four essential viewpoints: function, costs, time, and quality. These viewpoints are discussed, individually analyzed, and serve as a basis for further research. The whole framework is developed and validated according to Design Science Research Methodology (DSRM). Individual components are evaluated using a survey among a group of selected IT managers. Proof of concept is then established by a case study on framework use in a real organization. This case study covers strategy specification, business--IT alignment, specifying service architecture and its interconnections, outsourcing, and management of the ICT service portfolio.

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...

Ellipsometry of Thin Films
Novotný, Zbyněk ; Navrátil, Karel (referee) ; Nebojsa, Alois (advisor)
Diploma thesis deals with ageing process of thin films of Co and Cu on Si substrate, prepared by the IBAD method. The process of film ageing, which depends on time of exposition to the atmosphere at room conditions, was investigated with spectroscopic ellipsometry (VIS+UV) and atomic force microscopy. In case of thin Co films, approximately four days long incubation period was observed. During this time period, a change in the optical parameters of the film occurs without a measurable change of the film topography. Using non-contact atomic force microscopy, a growth of the transitional film in the island growth regime was observed. During the ageing of thin Cu films, two stages of growth of the transitional layer were observed - nucleation stage and growth stage. Both of these time periods of the transitional layer growth show direct logarithmic dependence. Using non-contact atomic force microscopy, the growth of the transitional film was observed. Using atomic force microscopy in non-contact regime, time dependent measurement was done and the process of forming of one monolayer of the transitional layer was documented. Within the diploma thesis, a series of experiments on ultra high vacuum system were performed in order to investigate phase transformation of thin Fe films (22 monolayers) on Cu(100) stabilized by CO absorption. The transformation from fcc phase to bcc phase was induced by Ar+ ion beam bombardment with the ion energy in the range (0.5-4) keV. The process of phase transformation was observed by surface magneto-optic Kerr effect, Auger electron spectroscopy and low energy electron diffraction.

Revitalization of the former Bata's factory in Zlin
Horníčková, Nela ; Lindner, Milan (advisor) ; Zelený, Martin (referee)
Bachelor's work is focusing on problematics of monument care, redevelopment and conservation of industrial culture heritage. Theoretical part is closely connected to the problematics this work is dealing with. Practical part is focusing on re-use of factories nowadays, on change which is visible from since the area was founded, by the time we are looking for the new options and opportunities for its use and purpose. Also the attempt is to look more closely if today's function of the area is on behalf of inhabitants needs and whats more if there is still a bit of Bata's legacy and atmosphere which the city surely deserves.

Selected psychological connections of changes in teachers' profession and their profesional preparation
Štětovská, Iva ; Gillernová, Ilona (advisor) ; Vališová, Alena (referee) ; Dobrovská, Dana (referee)
The thesis introduces a rather unusual continual discussion concerning the context of social changes and their impact on school life, pre-gradual preparation, and professional achievement of teachers. The text surveys the connectedness between recent social changes and the development of professional institutions, especially schools. The author considers gradual weakening of primarily educational function of schools and their shift of social responsibility toward educative and socializing commitments. As a consequence of such changes special attention is paid to current teachers' position and modifications of their professional activities. The author attempts to state new teachers' competences and highlights of their work. She asks what new demands can be observed in the course of teachers' professional preparation. Regarding the key position of relationships at current schools, the text focuses on communication patterns at school, which are fulfilled via relationships. The author discusses social support problems in details as they represent a crucial factor of teachers' work. The text introduces various approaches to a safe feedback to teachers. Particular examples include methods of video- interaction guidance and Balint groups applied to teachers' work. Regarding psychological applications and the...

The endocrine function of adipose tissue and its importance for initiation and development of insulin resistance and diabetes
Haluzík, Michal ; Schreiber, Vratislav (advisor) ; Marešová, Dana (referee) ; Šeda, Ondřej (referee)
Endocrine production of adipose tissue is a very complex process affected by numerous endogenous and exogenous stimuli. Peroxisome proliferator-activated receptors-alpha (PPAR-) are important modulators of metabolic processes which can also affect endocrine function of adipose tissue. Recently, numerous novel factors produced by adipose tissue with important metabolic effects were identified. Some of them can directly bind PPAR receptors. One of the examples of these factors is fatty acid binding protein 4 (FABP4) which can directly bind PPAR receptors and indirectly modify its activation by changing availability of endogenous PPAR ligands -free fatty acids. We hypothesized that the mechanism of action of PPAR receptors to metabolic processes may partially lie in their complex interaction with adipose tissue-derived hormones. The unraveling of these interactions may have important consequences in finding approaches to treat patients with type 2 diabetes mellitus. (...) In summary, our data show an important role for the interplay of PPAR activation and endocrine function of adipose tissue in metabolic regulations which may have important clinical consequences.
