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.

Schmidt, Róbert ; Maryška, Miloš (advisor) ; Sládek, Pavel (referee)
The main goal of master thesis is to analyze and propose possible low cost Business Intelligence solution with open source technologies and comparison of available tools for implementation in middle size company. We compare Pentaho and Jaspersoft tools implemented on local hardware and cloud environment with Microsoft Azure services. The theoretical part focuses mainly on understanding the business intelligence and its architecture, because architecture is an important part of the work. Actual tools are designed as stand alone modules for specific activities in the business intelligence lifecycle. Low cost tools are often connected with open source technologies and cloud computing. This part of the work contains explanation of these terms and their advantages and disadvantages for our chosen target group of companies. The analytical part includes defined parameters by which it is conducted analysis of tools and their comparison. Business Intelligence solutions are divided according to arcitectural layers. The evaluation criteria are divided into financial, technical and user category. In conclusion, chosen tools are compared and evaluated. The main contribution of this thesis is comparison of open source business intelligence tools for implementation in middle size company. According to the EU directive, middle size company does not exceed 250 employees or profit is less than 50 million euros. The reader can compare the different solutions and their pitfalls or shortcomings that could be critical for the implementation.

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.

Food supplements and iodine supplementation in pregnancy
VAVROUŠKOVÁ, Edita
Iodine is a trace element tremendously important for thyroid gland hormone production. It affects normal evolution of brain, especially in the time of intrauterine development and in the first year of child's life. Deficiency of iodine can lead to creation of pregnancy goiter, it also decrease the probability of carrying fetus to term and increase the probability of disorder in psycho-motoric evolution of child. Czech Republic is geographically lined up among the regions with lack of iodine in natural sources and food. However, nowadays the iodine deficiency is considered to be managed. But risk groups of population still exists, especially pregnant women can be endangered by lack of iodine, because the need of iodine intake in pregnancy increases to 200 250 ug per day and this level must be ensured. Consumption of food rich in iodine can cover the increased need of iodine. Significant source of iodine is milk and milk products. Another source is table salt enriched with iodine, but its daily intake is limited. Rich sources of iodine like sea fish, sea products and seaweed rarely occur in our diet. The goal of thesis was to evaluate intake of dietary supplements with iodine by pregnant women and evaluate women's awareness of higher iodine need and iodine food sources. Quantitative research in form of questionnaires was chosen for getting information from higher number of individuals. The questionnaire consists of 15 questions. Answers were gained from 118 respondents living in Central Bohemia, Moravia-Silesia region, Liberec region, region Highlands and South Bohemia. Questionnaire was distributed to gynecological ambulances by employees of State health institution. I visited gynecological ambulances in South Bohemia personally. By evaluation of questionnaire was found out that dietary supplement with iodine use 63 % pregnant women in researched population. All respondents always use only one type of dietary supplement. Among the most used belong "Chytré miminko", "GS mamavit" and "Femibion 800". 68 % of respondents know the importance of higher iodine intake in time of pregnancy. Question about daily recommended dosage was correctly answered only by 35 % of respondents. As a food sources of iodine the pregnant women know sea fishes, sea products, seaweed and table salt enriched with iodine. But 90 % of respondents are not familiar with milk and milk products as important source of iodine. Pregnant women should be better informed about importance of sufficient supply of iodine and about sources of iodine by gynecological ambulances. Information about mentioned issues should occur in magazines, education materials and internet articles more often. Respondents were notified of issues and important role of iodine in time of pregnancy by questionnaire. It is very probable that women found correct answers on the internet or in publication for expectant mothers after filling in the questionnaire.

Pick´s disease and the specifics of the nursing care of a patient with this disease
KOPKAŠOVÁ, Lenka
Pick's disease is a degenerative-atrophic process that primarily affects the frontal and temporal lobes of the brain. Besides Alzheimer's disease, it is a lesser known form of dementia which affects people of younger age. Although the exact range of Pick's disease occurrence varies in the literature, the average reported age is between 50-60 years. The disease can change eating habits, cause emotional swings, inappropriate behaviour and sloppy appearance of the patients. The behaviour to others is often selfish, the patients are unable to listen to others and ignore their surroundings. Pick's disease is also characterized by inappropriate sexual behaviour. Globally, the number of dementia patients is still growing and according to expert guesses the increase will continue. Nursing care for patients with dementia is therefore becoming a very actual topic as dementia is called a quiet epidemic of our century. Nurses in their departments quite frequently encounter patients suffering from dementia of various origins at different stages of disability and the staff at healthcare facilities often regard these people as a burden. The aim of this thesis, which is called Pick's Disease and Specifics of Nursing Care for Patients with this Disease, is, based on the theoretical knowledge, to map definitions and diagnosis of Pick's disease, to define the needs of such a patient, and to list the most common problems in the nursing care. It focuses on people with dementia within medical facilities. For proper understanding of the problem, the thesis starts with the anatomy and physiology of the brain and the description of cognitive functions which are affected by the dementia syndrome and the definition of dementia. Based on the studied literature, dementia is divided according to various criteria. It has been found out that dividing dementia is not entirely uniform, but the essential facts and overall opinions of the authors do not diverge. Pick's disease belongs to a group of frontotemporal dementia and its position in this group has changed over time, as it is recorded in the literature. The thesis includes recommendations resulting from the studied literature in the approach to patients with dementia and emphasizes personal communication with the patients and empathetic and humane approach. Although medicine cannot prevent dementia, an early diagnosis of a specific type of dementia and correctly targeted treatment can increase the quality of life not only of the patients but also of their families. I have chosen this topic because I find it very current and interesting. During my nursing practice at the Surgery Department and Aftercare Department, I have met patients suffering from dementia and I did not know how to properly and efficiently communicate with them. For the theoretical part of my work, the methods of explanation, synthesis and induction on the basis of Czech and foreign information sources have been used. The most frequently quoted Czech authors in my thesis are doc. MD. Roman Jirák, PhD., the head of the center for diagnosis and therapy of Alzheimer's disease at the psychiatric clinic of the General University Hospital in Prague, the 1st Medical Faculty of Charles University. This thesis can serve as an informational and educational source both for nurses and the general public who may experience the disease within their families. It would be considered a great success if it helped nurses or family members to diagnose Pick's disease or other dementia at an early stage.

Biomass as a base material for the production of fuels and energy
HUBAČ, Tomáš
Nowadays, with the dwindling fossil fuels there is need to find a new source of energy. One of interesting possibilities is to use biomass. The energy from biomass can be obtained in many ways. There are three main directions. Thermochemical conversion which involves incineration, gasification and pyrolysis. The biochemical conversion which comprises of anaerobic fermentation, aerobic fermentation and alcoholic fermentation. Last option is physical-chemical conversion comprising of esterification. Subsequently gained biofuel is divided into I, II, and III generation according to the method of production and resources. Alternatively derived biofuel equals, and sometimes surpasses the fossil ones. Biofuel has basic division into liquid (bioethanol, bio-oil, etc.), solid (wood pellets, briquettes, etc.) and gases (biogas, etc.). We should mention the need to improve the efficiency of existing technologies and to invent new economical and environment-friendly techniques.
