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.

Old or new in the Antonín Dvořák´s Serenade op. 44
Kolátorová, Petra
The paper considers the genre of the orchestral serenade in the context of reflections on “old” and “new”. The serenade form was rediscovered for the 19th century by the German composer Johannes Brahms, who built on the legacy of Viennese classicism. In the case of Antonín Dvořák’s Serenade for Wind Instruments, op. 44, it is also possible, on the basis of analysis and historical connections, to speculate about classicist models, specifically Wolfgang Amadeus Mozart’s Serenade in B Flat Major, KV 361/370a. Dvořák took Brahms’ initiative a step further, with his Serenade op. 44 presaging the trend in development towards neoclassicism, which, however, was to come much later.

Nurse in the Course of Time - the History of the Nursing Profession in the Czech Lands
KOPULETÁ, Martina
The aim of this thesis is to map the historic development of the nursing profession in Czech nursing from the past to the present. The Bachelor thesis is composed purely theoretically. The development of nursing profession is described in its important millstones. To gain information, it was necessary to peruse a considerable amount of bibliographic publications, research papers and internet sources. Further off the theoretical part was enhanced by memories of former nurses who used to work at hospitals after the World War Two and during the communist regime. The nursing profession has being formed since time immemorial and this process still continues. Wars, social and political situation, scientific progress and new knowledge in medicine had a great impact on the foundation of nursing. The nursing profession had to go through a very long, winding and sometimes even thorny journey to get the position of independent scientific discipline, as it is nowadays. The nursing profession routs of in the past. First part of the thesis deals with nursing in the period of the early Middle Ages and describes its first two stages. First stage in nursing dealt with lay nursing care which was performed by family members in their homes. Second stage, charitable nursing, came along with faith in God and Jesus Christ. The church caretakers tended the poorest and needy people in hospitals and poorhouses. A great development in nursing, that also means nursing profession and medicine, was during Crimean War. This period is known as third stage of nursing activity that is the organised nursing. We owe it to Florence Nightingale, Nikolay Ivanovich Pirogov and Jean Henry Dunant. These personalities of world nursing gave the nursing profession solid foundation and order. Next part deals with acquisition of professional skills. The origins of nursing education in this country were significantly influenced by emancipation movements in 19th century led by Eliška Krásnohorská and Karolína Světlá who fought for women's rights and education for women. We have to be grateful to these women for establishment of the first nursing school in Austria-Hungary which was founded in 1874 in Prague. The nursing profession gained importance by foundation of this school and professional aiming education of nurses started being to be formulated. During the time until the World War Two it was mainly members of religious orders who cared about the ill in our hospitals. Nursing education was procured by Česká zemská škola pro ošetřování nemocných before the establishment of Czechoslovakia. At the beginning of the First Czechoslovak Republic civil nurses and graduate nurses were gradually integrated into hospitals where they most frequently hold the position of nurses in charge. Further the Bachelor thesis is about social and working conditions of nurses at ward. The conditions, in which the patients were hospitalized, are described as well.Nursing profession in the course of World War Two (1939 - 1945) monitored a specific development. Nuns had to leave hospitals and were replaced by German caretakers. After the war German doctors and nurses were displaced back to Germany. This unfavourable situation was solved by the return of religious orders, but it did not last long. In the 1950´s they had to leave hospitals again and definitively forever.The bachelor thesis further describes the 1990´s which are the years of enhancing the quality of nursing care and led to gradual gaining of independence in the field of nursing.Finally, personalities of Czech nursing care that anyhow, mainly by their work, contributed to the establishment and development of nursing profession are mentioned at the end of the bachelor thesis.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Optimization of network flow monitoring
Žádník, Martin ; Lhotka,, Ladislav (referee) ; Matoušek, Radomil (referee) ; Sekanina, Lukáš (advisor)
The thesis deals with optimization of network flow monitoring. Flow-based network traffic processing, that is, processing packets based on some state information associated to the flows which the packets belong to, is a key enabler for a variety of network services and applications. The number of simultaneous flows increases with the growing number of new services and applications. It has become a challenge to keep a state per each flow in a network device processing high speed traffic. A flow table, a structure with flow states, must be stored in a memory hierarchy. The memory closest to the processing is known as a flow cache. Flow cache management plays an important role in terms of its effective utilization, which affects the performance of the whole system. This thesis focuses on an automated design of cache replacement policy optimized to a deployment on particular networks. A genetic algorithm is proposed to automate this process. The genetic algorithm generates and evaluates evolved replacement policies by a simulation on obtained traffic traces. The proposed algorithm is evaluated by designing replacement policies for two variations of the cache management problem. The first variation is an evolution of the replacement policy with an overall low number of state evictions from the flow cache. The second variation represents an evolution of the replacement policy with a low number of evictions belonging to large flows only. Optimized replacement policies for both variations are found while experimenting with various encoding of the replacement policy and genetic operators. The newly evolved replacement policies achieve better results than other tested policies. The evolved replacement policy lowers the overall amount of evictions by ten percent in comparison with the best compared policy. The evolved replacement policy focusing on large flows lowers the amount of their evictions two times. Moreover, no eviction occurs for most of the large flows (over 90%). The evolved replacement policy offers better resilience against flooding the flow cache with large amount of short flows which are typical side effects of scanning or distributed denial of service activities. An extension of the replacement policy is also proposed. The extension complements the replacement policy with an additional information extracted from packet headers. The results show further decrease in the number of evictions when the extension is used.

Practical use of theatroterapy in the activation process of adults with intellectual disability
REJŠKOVÁ, Denisa
The aim of my bachelor thesis "A Practical Usage of Theatrotherapy During a Stimulation of Adult People with Mental Handicap" was to create, execute and evaluate a theatre performance focusing on a stimulation of mentally disabled adults. During leisure activities, it is possible to offer to mentally disabled people such activities that develop their personalities universally, lead towards their own activity and creativity. However, the mentally disabled people´s selection of activities is limited in comparison with the intact ones. Considering an offer of leisure activities for the target group, I decided to use theatrotherapy which has been created for them and then to implement a theatre performance. According to the specialised literature, by using it, it is possible to reach positive results in the field of communicative and locomotive skills as well as the memory and social relations. This thesis consists of three chapters. The target group will be defined in the first chapter in which I define the term of mental disability, characterise adult people with medium or severe mental disability and specify their social, mental and locomotive limitations in details. I define the theatrotherapy, describe its development, aims and methods in the second chapter. Simultaneously I mention it as a means of stimulation in the conclusion of this chapter. Theoretical part of the work is followed by in the third, practical chapter. I prepare a theatre performance based on specialised literature which I implement and evaluate here. The theatre performance was based on principles and rules of theatrotherapy. An original script adapted to the target group was used for its implementation. Classical teaching methods and drama teaching methods were used for rehearsing, namely methods verbal, graphically demonstrative, practical skills gaining, roleplaying, methods and techiques of training games and exercises, evaluation and reflection. During the evaluation and objective technique was used which aims for an analysis of actor´s activity, and a subjestive technique which aims for self-evaluation and actor´s feedback. The above mentioned activity was supported by IN Civic Society and ten people with medium and severe mental disability aged 25-45 participated. There was a process of involvement during a making of the performance and positive results in the field of communicative and locomotive skills were reached. The actors experienced new and unusual situation during the performance. They met new people too because some students of the University participated too. This resulted in social integration. The bachelor thesis is meant as an inspiration for the personnel of institutions providing social services.
