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.

Cooperation between a nurse working at a children{\crq}s ward and an anaesthetic nurse in care of a child patient in pre-operation, per-operation and post-operation periods
ŽÁKOVÁ, Lucie
I selected the topic of the diploma thesis ``Cooperation between a nurse working at a children{\crq}s ward and an anaesthetic nurse in care of a child patient in pre-operation, per-operation and post-operation periods{\crqq} because I am very interested in the work of nurses and in preparation of children and their parents in these periods. These entire periods and the associated activities are very demanding and burdening for all the involved parties. The cooperation and communication between the anaesthetic nurse and the children{\crq}s nurse is crucial for the child to cope with the period. The objective of the diploma thesis was to ascertain the opinions of anaesthetic and children{\crq}s nurses on their cooperation, and to find out whether the cooperation between anaesthetic and children{\crq}s nurses influences satisfaction of a child{\crq}s needs in the concerned periods. The theoretical part of the diploma thesis addresses paediatrics and segmentation of childhood, anaesthesiology and the specifics of childhood, children surgery and nursing care of children in three operation periods in general terms. The practical part is divided into a quantitative and a qualitative subpart. The quantitative subpart is focused on cooperation between anaesthetic nurses and nurses working at the children{\crq}s ward, and uses the data collected by means of a questionnaire, while the qualitative subpart ascertains whether the cooperation between nurses has an influence on the needs of children in the concerned periods, and uses the data obtained from observation of children and interviews of nurses. The summary of the results revealed that hypothesis 1 ``Anaesthetic nurses and nurses working at a children{\crq}s ward cooperate in the pre-operation period{\crqq} was confirmed. Hypothesis 2 ``Anaesthetic nurses and nurses working at a children{\crq}s ward cooperate in the post-operation period{\crqq} was confirmed. Hypothesis 3 ``Anaesthetic nurses are interested in improvement of cooperation with nurses working at a children{\crq}s ward{\crqq} was confirmed. Hypothesis 4 ``Nurses working at a children{\crq}s ward are interested in improvement of cooperation with anaesthetic nurses{\crqq} was confirmed. The qualitative subpart revealed that cooperation between nurses influenced satisfaction of a child{\crq}s needs in the concerned periods. The findings of this diploma thesis may be used by children{\crq}s and anaesthetic nurses or by other persons interested in this issue for the sake of better preparation of a child for the operation period, better satisfaction of a child{\crq}s needs in the concerned period, and provision of more comprehensive care in the period in general.

Awareness of women about nutrition problems such as breast cancer prevention
STAŇKOVÁ, Denisa
This thesis focuses on the awareness of women of the nutrition issue as the prevention of breast cancer. The aim of this thesis is to find out whether the women have enough information about nutrition and life style as the prevention of breast carcinoma, where they look for information, if they are interested in this issue and whether they consume food that could work as the prevention. Another goal is to detect possible differences in the attitude to the prevention between women without the potential risk and women with the increased risk, i.e. women over 45. Research questions were determined as follows: "What is the knowledge of women about the issues of nutrition as the prevention of breast cancer?", "What is the proportion of the food that has preventive effect on the rise of breast carcinoma and, on the contrary, the food that supports the tumour growth in the eating habits of women?", "Where do women get information on this issue?", "What is the difference in awareness and consumption of food between women without the potential risk and women with the increased risk, i.e. over 45. The thesis is divided into two parts, a theoretical and a practical one. In the theoretical part I focus on the breast anatomy, basic information on breast cancer and risk factors that are divided into influenceble ones and non-influenceble ones. In the most extensive part of my thesis focuses on the influenceble factors, that is nutrition and life style. I focus especially on nutriments, food and other life style factors that are most connected with breast cancer and have antitumour effects or, conversely, support the tumour growth. The practical part was made by means of a questionnaire which I placed on the Internet and handed out in the waiting room at the general practitioner. The questionnaire was anonymous with 34 questions of a closed and semi-enclosed type. Questions concerned nutrition and life style in relation to the risk of breast cancer and were devised to answer previously defined research questions. The questionnaire survey took place in January and February 2013. I acquired 105 filled in questionnaires from which I randomly chose 86 to obtain two numerously equal groups of women without the potential risk and with the increased risk, i.e. over 45. The result of the research part is that women do not have much information on the life style in connection with the breast cancer. Some respondents, while selecting food with preventive effect, were only guessing and often also marked food which was not related to the breast carcinoma at all. About one third of the respondents even believe that nutrition and other factors are not related to this disease at all. One third of the respondents also stated that they had no interest in learning more information on this issue. Women that have some information usually get it from the magazines and from the Internet. In terms of eating habits, the food of most respondents does not reach the needed quantity to have preventive effects. On the other hand, the food and drinks that support tumour growth do not occur on the menu of the respondents very often. While comparing answers of the women younger 45 and the older group of respondents, it was found out that the younger respondents showed greater unawareness of this issue. No significant differences were recorded in other questions. The results of the survey are graphically processed and evaluated in the final part of this thesis. I suppose this thesis is the contribution to clarifying the current situation of this issue. I believe that the topic of my thesis is up-to-date and that I managed to summarize the most significant information regarding this topic and fulfil the aims I set down. I would be very glad if my work led to the contemplation of this issue and subsequently to a more extensive propagation of the breast cancer prevention.

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.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.
