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.

Proposing the financial performance prediction index for decision support of the hospital management
Hajdíková, Taťána ; Černá, Anna (advisor) ; Lieskovská, Vanda (referee) ; Lazar, Jaromír (referee)
Dissertation thesis deals with the managerial needs in the area of financial health. Managers need a tool to reveal the impending financial failure or to assess the financial quality of the organization. They link their decisions to performance, ability to pay, employee productivity, financial resources and financial risk. In the theoretical part of the thesis it is necessary to explain the non-profit sector and its connection with the hospital environment. It is also necessary to introduce models used both in the Czech Republic and abroad, which share common elements. The basic aim of this thesis is to propose a financial performance prediction index for decision support of the hospital management, the owners of hospitals and insurance companies. To achieve the basic goal, three sub-goals must be accomplished. The first goal is to divide the hospitals into healthy and unhealthy by using the multi-criteria methods. The second goal is, based on an expert approach with the support of statistical methods, the selection of indicators appropriate for the hospital environment and the third goal is to find a suitable method for the determination of weighted representation of individual indicators in the proposed index and to assemble the final form of the new financial index for the hospital environment.

The Image of the Artist in Czech Feature Films after 1948
Šlingerová, Alena ; Klimeš, Ivan (advisor) ; Přádná, Stanislava (referee)
After the Czechoslovak coup d'état of 1948, the cultural politics of the Communist Party became the only power that should organize, regulate and evaluate cultural affairs. This brouht radical changes of the status of artists. That artists who belonged to the rank of intellectuals had to follow needs of the new kind of society. They accepted orders from above and their activity was strictly controlled. Proletarian amateurs and folk art were officially encouraged. The examples of the progressive art were found in the USSR and also among personalities from the history of the national culture. Cinematography, to which was placed a requirement of topicality, also presented the new image of the artist. The most noticeable results were reached in biografical films about our classics and films exposing folklore and cultural life of the working class. The integration of an intellectual artist into the new society became a pivotal theme in movies Písnička za groš and Nezlob, Kristino. As episodic characters, we can find also completely negative types of artists - enemies of that new society. This spectrum corresponds to a general typology of people that was used in art, journalism and public speech in general: mature, confused and totally inadaptable (designed to be displaced). Exeptional cases of...

Puppies and young dogs nutritions
Šabatová, Kateřina ; Hučko, Boris (advisor) ; Plachý, Vladimír (referee)
Puppies and young dogs nutritions Summary In this work I have attempted to summarize the most important aspects in nutrition of puppies and dogs in growth. The introduction describes the digestive tract and also the changes that have occurred due to domestication. Next is explained the importance of nutrition and water in nutritional requirements of a dog. Important are needs of nutrients and energy that are necessary to maintain the provision of the necessary vital functions. The basic components of food are proteins, saccharides, lipids, minerals and vitamins. I explain the necessary proportions, the amounts and the possible consequences of their lack in food. I focus on essential fatty acids, which in recent years are subject to frequent explorations and their pros and cons are not yet fully understood. I also mention ballast and significant specific active substances. Nutrition of pregnant and lactating females is often neglected, but for puppies it is a very crucial period. The influence of nutrition of pregnant females to the size and weight of newborn puppies has been proved. Further I deal with nutrition of puppies immediately after birth, I explain the composition of colostrum and its effect on the immunity system of the puppy. I also compare ratios of nutrients in the colostrum and milk. Further, I deal with the feeding of the individual at the time of weaning and in different growth periods. There are many possibilities of feeding puppies from after weaning until adulthood described in books. With the new knowledge about nutrition the ways of feeding our dogs have inevitably changed , but also the dogs' nutritional requirements have changed due to the conditions where and how they live and what their nutrient needs are according to their sport, breeding or other use. Currently, there is a possibility of a commercially produced complete nutritional diet or home-prepared fresh food - cooked or raw- barf. In the last chapter, I summarized possible aspects of malnutrition and its potential consequences. I described the most common problems associated with inadequate nutrition of growing dogs such as obesity as well as malnutrition, which also adversely affects the individual. The influence of proper nutrition of the puppy on its growth is clear. If we neglect the nutrition of the dog in the first two years of its life, the consequences are often irreversible.

Arctic tundra dendrochronology
Lehejček, Jiří ; Svoboda, Miroslav (advisor) ; Monika, Monika (referee)
Historically unprecedented environmental change in the Arctic ecosystems is often given into the context of its past and possible future development. In the region where instrumental meteorological observations are scarce archives need to be investigated in order to address this issues. The comprehensive synthesis one of the archives: long-live circumpolar evergreen Juniperus communis L. shrub is presented here. 20 individuals from southwest Greenland were investigated at the cell anatomy level to understand the ecology of the species and unhide its potential for environmental and climate reconstructions. The findings are as follows:
i) Stop of exponential cross-sectional conduit-lumen widening with increasing age is in contrast with conduit-lumen nature of trees. This indicates that shrubs do not need to saturate their water and nutrient demands via traits of classical hydraulic conductivity law but rather developed different mechanisms. Extreme weather conditions result in prostrate growth form. However, different weather factors probably influence shrub growth differently: While snow and wind act mechanically (a), temperature influences the form of growth physiologically (b). a) So long as the young shrub stem has high resilience to bend back to an upright position after snow melt and so long as it can withstand the wind during the vegetation season it most likely grows upright and the conduit-lumens widen. b) Temperature, resp. freeze-thaw events are responsible for the shrubs preference of safety (finite size of conduit-lumens) over hydraulic efficiency, thus not allowing for more primary growth. All of these (and other) factors are apparently working together and the transition of vertical to more horizontal growth is gradual. As a consequence, the conduit-lumen sizes may not have to be further increased (due to ecophysiological restrictions possibly also must not) because water is no longer transported against gravity.
ii) Observed age/growth trend has to be taken into consideration for further employment of the wood anatomical parameter in paleoenvironmental studies. That is, shrub cell parameters can only be used for this purposes if correctly detrended. This allows for more accurate as well as longer reconstructions because youth trend was often neglected in reconstructions based on shrub annual-rings.
iii) The south-western Greenland Ice-Sheet (GrIS) melt rates reconstruction is presented for the whole 20th century. This part of GrIS is considered as the most active. According to the presented reconstruction current GrIS melt rates are not uncommon for the last century being comparable to first decades of 20th century. This finding is particularly important contribution to the debate on Atlantic meridional overturning circulation (AMOC). Too high fresh water inputs into the Northern Atlantic from GrIS melting may slow down or even stop the AMOC which would result in more continental climate in Europe. Presented results indicate that this threshold lies higher than observed current melt rates of GrIS.
Fascinating Juniperus comunnis species has shown to be able to address many ecological as well as environmental open questions and due to its longevity and abundant distribution has a great potential to become an important player in the Arctic research.

The bachelor's thesis entitled "Design and implementation of e-learning in the area of interest" deals with buying used cars. The essential part of this work is a creation of e-learning course for buyers and other people interested in this area which aims to improve their knowledge. The participants will get an overview of the most common situations and problems they can meet when buying a used car. The theoretical part presents an overview of the topics of the issue of purchase of used cars. It may serve as a theoretical guidance to the e-course, it brings its content. The topics are based on the analysis of information from printed and electronic sources, supplemented by experiences of the author and experts in the field. The practical part deals with the creation of an e-learning course. It contains an analysis of the needs of buyers, the reasons for the creation of the course and the requirements of it, its objectives, a description of the used authoring tool eXe and graphic creation process from the creation of the course after its publication in steps. All this is complemented by the feedback from six volunteers who have expressed an interest in testing the course and then doing a review. Before the creation of the course it was necessary to analyze the situation and find out why such a course is needed. The acquired knowledge was then processed in the course by the synthesis method. For the evaluation method it was used a short personal interview where the author examined satisfaction with the course, its possible shortcomings and suggestions for improvements or enhancements.

Employment in a state-funded institution
Brožová, Milena ; Světlíková, Daniela (advisor) ; Pikola, Pavel (referee)
This bachelor thesis is focused on employment in a state-funded institution. It is divided into a theoretical and an empirical part.
The theoretical part deals with analysis of legal regulations and their interpretation. The method of description is used in this part. The focus in legal regulations is on the problems of a state-funded institution, namely on the legal position and functioning and on management. The focus is also on labour relations, from the general definition to the conclusion of employment for a fixed period of time. The analysis of legal regulations is complemented with interpretations of authors of specialized publications.
Direct and indirect quotations are used in the text and are marked with footnotes.
The empirical part of this thesis deals with the application of legal regulations in a particular state-funded institution. The order of researched areas is in accordance with the theoretical part. The method of comparison and study of documents and internal regulations are used for analysing the data.
The primary research has shown that the legal regulations are applied without difficulty. The discovered discrepancy between the used terminology and the terminology in the Civil code does not invalidate legal documents and thus there is no need to mark it as a defect which needs to be fixed. Suggestions for discussion have been made, for which measures were proposed in the concluding part. The suggestions relate to arrangement of employment for a fixed period of time and its change to permanent contract and to allowance from the founder as a financial mean of a state-funded institution.

New Methods for Increasing Efficiency and Speed of Functional Verification
Zachariášová, Marcela ; Dohnal, Jan (referee) ; Steininger, Andreas (referee) ; Kotásek, Zdeněk (advisor)
Při vývoji současných číslicových systémů, např. vestavěných systému a počítačového hardware, je nutné hledat postupy, jak zvýšit jejich spolehlivost. Jednou z možností je zvyšování efektivity a rychlosti verifikačních procesů, které se provádějí v raných fázích návrhu. V této dizertační práci se pozornost věnuje verifikačnímu přístupu s názvem funkční verifikace. Je identifikováno několik výzev a problému týkajících se efektivity a rychlosti funkční verifikace a ty jsou následně řešeny v cílech dizertační práce. První cíl se zaměřuje na redukci simulačního času v průběhu verifikace komplexních systémů. Důvodem je, že simulace inherentně paralelního hardwarového systému trvá velmi dlouho v porovnání s během v skutečném hardware. Je proto navrhnuta optimalizační technika, která umisťuje verifikovaný systém do FPGA akcelerátoru, zatím co část verifikačního prostředí stále běží v simulaci. Tímto přemístěním je možné výrazně zredukovat simulační režii. Druhý cíl se zabývá ručně připravovanými verifikačními prostředími, která představují výrazné omezení ve verifikační produktivitě. Tato režie však není nutná, protože většina verifikačních prostředí má velice podobnou strukturu, jelikož využívají komponenty standardních verifikačních metodik. Tyto komponenty se jen upravují s ohledem na verifikovaný systém. Proto druhá optimalizační technika analyzuje popis systému na vyšší úrovni abstrakce a automatizuje tvorbu verifikačních prostředí tím, že je automaticky generuje z tohoto vysoko-úrovňového popisu. Třetí cíl zkoumá, jak je možné docílit úplnost verifikace pomocí inteligentní automatizace. Úplnost verifikace se typicky měří pomocí různých metrik pokrytí a verifikace je ukončena, když je dosažena právě vysoká úroveň pokrytí. Proto je navržena třetí optimalizační technika, která řídí generování vstupů pro verifikovaný systém tak, aby tyto vstupy aktivovali současně co nejvíc bodů pokrytí a aby byla rychlost konvergence k maximálnímu pokrytí co nejvyšší. Jako hlavní optimalizační prostředek se používá genetický algoritmus, který je přizpůsoben pro funkční verifikaci a jeho parametry jsou vyladěny pro tuto doménu. Běží na pozadí verifikačního procesu, analyzuje dosažené pokrytí a na základě toho dynamicky upravuje omezující podmínky pro generátor vstupů. Tyto podmínky jsou reprezentovány pravděpodobnostmi, které určují výběr vhodných hodnot ze vstupní domény. Čtvrtý cíl diskutuje, zda je možné znovu použít vstupy z funkční verifikace pro účely regresního testování a optimalizovat je tak, aby byla rychlost testování co nejvyšší. Ve funkční verifikaci je totiž běžné, že vstupy jsou značně redundantní, jelikož jsou produkovány generátorem. Pro regresní testy ale tato redundance není potřebná a proto může být eliminována. Zároveň je ale nutné dbát na to, aby úroveň pokrytí dosáhnutá optimalizovanou sadou byla stejná, jako u té původní. Čtvrtá optimalizační technika toto reflektuje a opět používá genetický algoritmus jako optimalizační prostředek. Tentokrát ale není integrován do procesu verifikace, ale je použit až po její ukončení. Velmi rychle odstraňuje redundanci z původní sady vstupů a výsledná doba simulace je tak značně optimalizována.
