Trust and Reputation in Distributed Systems
Samek, Jan ; Návrat,, Pavol (referee) ; Šafařík,, Jiří (referee) ; Hanáček, Petr (advisor)
This Ph.D. thesis deals with trust modelling for distributed systems especially to multi-context trust modelling for multi-agent distributed systems. There exists many trust and reputation models but most of them do not dealt with the multi-context property of trust or reputation. Therefore, the main focus of this thesis is on analysis of multi-context trust based models and provides main assumptions for new fully multi-contextual trust model on the bases of them. The main part of this thesis is in providing new formal multi-context trust model which are able to build, update and maintain trust value for different aspects (contexts) of the single entity in the multi-agent system. In our proposal, trust value can be built on the bases of direct interactions or on the bases on recommendations and reputation. Moreover we assume that some context of one agent is not fully independent and on the bases of trust about one of them we are able to infer trust to another's. Main contribution of this new model is increasing the efficiency in agent decision making in terms of optimal partner selection for interactions. Proposed model was verified by implementing prototype of multi-agent system when trust was used for agents' decision making and acting.

The contributions of the sections (NACE-CZ) to the creation of gross value added
BEDNÁŘOVÁ, Monika
The aim of this thesis was to evaluate the contributions of the sections (NACE-CZ) to the creation of gross value added. The first part of this thesis described the theoretical concepts relating to national economic gross value added. Analytical processes were used for the calculations, which may be used only if we are dealing with an additive link between individual factors. The sections' contributions to the creation of national eco-nomic gross value added were evaluated in the practical part, on the basis of the proc-esses set forth in the methodology. In the given time horizon, contributions by institu-tional sectors and groups of sections classified according to the level of technology showed a certain dependency on the actual economic cycle. Although the strongest in-stitutional sector is non-financial enterprises, they were the ones most affected during the crisis period, together with government institutions. On the contrary, the financial institution sector showed a strong position during the crisis period. In terms of the grouping of the sections according to the level of technology, the greatest contribution to national economic gross value added is by groups B1 and B2. The influence of the economic cycle was noted in all the groups but, according to the results, group C did not react quite as sensitively as the other groups.

Intraday trades
BOHINSKÝ, Petr
This thesis is focused on comparison of intraday and short term trades profitability using technical analyses by application the method of crossing moving averages between January 1st 2014 and August 1st 2016. Trading takes place on the basis of buying and selling signals of a generated technical indicator in the investment program Alapri and XTB. The traded indexes are DAX 30, S§P 100 and commodities gold and oil. The theoretical part of this work is devoted to the financial market, commodity market, describes intraday and positional trader and advantages as well as disadvantages of these markets. It also deals with technical analyses and explains basic investment terms. Practical part of the work is devoted to a description of the results modeled on real historical data. It is possible to determine on the base of back-tested results that the method of crossing moving average with the value of the instrument is better for short-term trades; in modeled example in daily graph than for intraday trades modeled in four-hour graph. Furthermore when modeling there was found that it is more profitable to buy instruments and let them be valorized by the financial market under given conditions. It means to buy them at the beginning of the investment period and sell at the end of this period without any buying and selling operations.

Application of Queueing Theory
VÁŇOVÁ, Eliška
The goal of this thesis was to understand Queueing Theory and use it for analysis of queueing system of hypermarket company PZV. Theoretical part is consists of basic iformations which is necessary to know for application of queueing theory. First chapter is about random variables, random event, random proces, stochastic and Poisson processes and Markov chains. Then was possible to describe queueing theory basic characteristics, parameters, analy-sis, classification and basic models. In the practical part was from the beginning analyze development of custo-mers going through cashier zone. On the base of analysis were customers divided into 4 groups. For these groups were counted characteristics and parameters, next was analyzed the system, but because data were too inaccurate, it was necessary to use different values for the groups and to count analysis for these values. The last step was to find number of cashiers to make system optimal. The result, it was 4 ca-shiers, was unfortunately not accurate. For better results it would be necessary to have more detail data.

Dance as a means of integration adults with intellectual disability
KRAUMANNOVÁ, Eva
The goal of the bachelor thesis called Dance as a means of integration adults with intellectual disability was to create, implement and evaluate a dance course focused on the development of social competences in adults with intellectual disability. The thesis deals with adults with intellectual disability and with a leisure activity focused on dancing. There is some space for the development of social competences in adults´ leisure time. In response to the current situation of leisure activities proposition for adults with intellectual disability. I found it beneficial to found a dance group of adults with intellectual disability, and at the same time a group of individuals intact in places unfamiliar to them. Based on an activity which may be implemented amusingly it is possible to develop an individual´s personality as well as his or her social competences, which become a presumption of a successful integration, universally. The bachelor thesis consists of four chapters.The first chapter defines the term ´intellectual disability´. Further on the attention is paid to the characteristics of the target group, i.e. adults suffering from a slight and medium mental retardation. Further on, the disability´s impact onto the human psyche as well as social area is described. In the second chapter the term ´dance´is defined and then the description of its usefulness within the leisure, artistic and therapeutic areas is given. In the third chapter the presumptions for a successful integration are described. In the conclusion of the theoretical part there is an interconnection made between the target group and the activity for developing social competences. The theoretical part of the bachelor thesis is continued with a practical part, the fourth chapter. It is a programme of a six-month course which I have set together based on the analysis of expert literature and my experience gained during the leadership of dance lessons and working with adults with intellectual disability. The programme will include work methods and an evaluation of partial activities. The six-month course was held in the school year of 2015/2016 and 6 intellectually disabled adults took part in it. Students of the University of South Bohemia joined the course. Partial goals were set for individual dance lessons and the activities were set so that they would develop social competences in participants non-violently and in the greatest extent possible. The course was implemented in the IN Civic Association facilities. To evaluate the activity and find out the progress within the area of the participants´ social competences, several development fields have been set. Several chosen social competences were divided into evaluation scales. The participants were evaluated at the beginning of the course and then again, six months later. The evaluation method chosen was my own observation. I focused on the evaluation of my own working, on group evaluation and the evaluation of each individual. Evaluation was also done on the part of each course participant, too. Dance lessons and activities connected have proven to be a suitable means for developing social competences in intellectually disabled adults. In five participants the values have risen in 5 10 out of 17 competences observed. A recourse occured in a participant who was going through a difficult life situation during the last two months of the course. Values have risen dramatically and in all participants in the area of group cooperation. Five participants made a progress in establishing and keeping eye contact and in starting a conversation. One participant has made a progress in the area of group performance, another one has made a progress in the area of independence and another one started to call the other participants by their names, as opposed to the beginning of the course. In general, the members of the group became more self-confident.

Nursing procedures in taking blood pressure
SEDLÁKOVÁ, Tereza
By blood pressure is meant lateral pressure or the side pressure of a blood column on the side of a vessel. The pressure is created thanks to the action of heart as a blood pump. This pressure is not the same in different parts of the bloodstream. By the blood pressure is meant the arterial pressure or pressure in the artery, so the pressure in big blood vessels. The highest values are reached in the expulsion phase of the heart action, which is called systole. The lowest values are reached in the phase of filling heart chambers, which is called diastole. The sole nursing procedures required in the process of taking a blood pressure reading are many and all must be followed. This thesis is composed of a theoretical part and practical part. Introduction to the theoretical part is composed of the main terminology from the physiology of blood pressure. In the theoretical part we follow with division on hypotension and hypertension, which are the most common diseases related to blood pressure, with diagnosis and recommendation for treatment. This thesis also offers information about measuring blood pressure by the invasive and the non-invasive method. The theoretical part is focused on the importance of the nurse in the process of measuring blood pressure with emphasis on her knowledge and practical skills.

Coping strategies in children´s fear and pain in relation to nursing care
PROCHÁZKOVÁ, Zuzana
For the nurse, taking care of hospitalized children is important not only pediatric nursing knowledge, personal and social preconditions, but also the theoretical and practical competency of methods and techniques, which are used for identification and effective influencing of pain and fear. The aim of this thesis was to identify the main sources of fear of the hospitalized preschool and young school age children and to find out the effective methods and principles of the cooperation with children, alternatively with their accompanying parents in order to moderate the fear of the small patient. Then the thesis tried to chart the nursing diagnostic and evaluation procedure of the pain and get the most used nursing methods of non-pharmacological pain relief. To obtain the necessary data, the qualitative research was used with a semi-structured interview as a research instrument. The first research group consisted of 12 nurses, the second group consisted of 12 children ´s patients of preschool and young school age. The majority of the asked nurses thinks, that children´s patients are afraid especially of non-familiar environment, then of the awaited pain and of the solitude without parents. However, the most patients said, that they were afraid especially of pain, then of non-familiar environment, restriction of their needs, hostile attitude of the medical staff and of the other neighbouring patients. They were also frightened of the death and of the darkness. Most reported nurses mean, that the most effective solution of the children ´s fear is the friendly attitude of the medics. They also mentioned the fact of taking the focus off the fear and the presence of the parents is also beneficial. The nurses ´ answers were in conformity with patients opinion in two fields - friendly attitude of the medics and taking the focus off the fear. Then the children mentioned abiding of their specifics in connection to falling asleep and the demand of beying treated by the same sister or by few same sisters. All respondents also talked about the benefit of parents presence. Regarding the principles of the cooperation, nurses answered the importance of united medical procedures, especially the proper way of information transfer. Then the respondents nurses mentioned the psychical and emotional support for children and their accompaniments, the atmosphere of confidence and the value of well done education. Also the need of calm, silence and privacy was stated. Unlike nurses, children and their parents regarding to principles of the cooperation prefer the psychical and emotional support, then the importance of enough information was mentioned. The fourth research question bears on the methods used for children pain monitoring. The nurses said, that the intentional interview with the patients or with the parents was used as a main technique, that was stated by patients as well. Research question number five said: What are the most used nursing methods of non-pharmacological pain relief at children? Most responded nurses mentioned the distraction of children attention from the painful incentive, then the importance of physical methods, relief position and purposeful preparation for the unpleasant intervention. Nurses also named the helpful contribution of the parents, relaxing exercises and the method of imagination. Regarding the pain treatment, it was noted, that all patients prefered the analgesic therapy. Then they quoted the distraction of their attention from the painful incentive, the friendly attitude of the medics, using the ice compress and the relief position. In the pain acute phase, children required mostly calm, comfort and privacy. All children also considered the presence of parents as very helpful. The theoretical and empirical part of the thesis are suitable for being studied by nurses taking care of children and it can be helpful for nursing quality improvement at children ´s wards in hospitals.
