On-line learning in real-time environments
Pacovský, Ondřej ; Spier, Emmet (advisor) ; Mrázová, Iveta (referee)
In this work, a novel reinforcement learning algorithm, Stimulus Action Reward Network (SARN), is developed. It is targeted for application in real-time domainswhere the inputs are usually continuous and adaptation must proceed on-line, without separate training periods. Another objective is to minimise the amount of problem-specific teacher(human) input needed for successful application of the algorithm. The SARN architecture combines a connectionist network and scalar reinforcement feedback by employing Hebbian principles. By adapting the network weights, connections are established between stimuli and actions that lead to positive feedback. Since the links between the input stimuli and the actions are formed quite rapidly, it is possible to use a large number of stimuli. This leads to the idea of using recurrent random network (Echo State Network) as a pre-processing layer. Prototype implementation is tested in Unreal 2004 game environment. The comparison with Q-learning shows that on the time scale of tens of seconds to minutes, SARN typically achieves better performance. When coupled with an Echo State Network, SARN requires a uniquely low amount of problem-specific information supplied by the teacher. These features make SARN useful for domains such as autonomous robot control and game AI.

Level of Quality Management and Safety Survey in Selected Hospitals in the Czech Republic.
MRÁZOVÁ, Iveta
Quality of care has become an important concept in present nursing. Accreditation is proper evidence and also the most efficient means to achieve high-quality care. Procedure of accreditation in the Czech Republic is most frequently administered at national level by the Joint Commission on Accreditation of the Czech Republic. The main objective of my thesis was to survey the setting of quality management and safety in selected hospitals in the Czech Republic. I used quantitative research and quantitative method {--} interviews and questionnaires in hospitals in České Budějovice, Český Krumlov, Písek, Prachatice, Tábor, Jindřichův Hradec from January to March in 2010. The qualitative part had the form of interviews with staff-nurses from above mentioned hospitals. For this part of work I set seven survey questions that had stemmed from the standards of accreditation of the Joint Commission on Accreditation. These questions referred to implementation of Programme of Quality Improvement and Safety of Provided Services, to the process of auditing, to the quality and safety data collecting, to the process of observing clients/patients´ satisfaction with nursing care, to the setting of report system of unusual and abnormal situations, to the setting of efficient system of complaints solving and to the standardization of health care. On the grounds of these interviews 9 hypotheses were set. These hypotheses were acknowledged in the quantitative survey among head nurses from above mentioned hospitals. 111 questionnaires were handed out, 82 questionnaires returned. The first hypothesis (proved) was: Head nurses play active parts in the Programme of Quality Improvement and Safety of Services Provided. The second hypothesis (not proved) was: Head nurses who perform the function of an auditor, have the certificate of accredited course. The third hypothesis (proved) is: The most frequent indicator of quality of nursing care is observation of patients´ satisfaction with provided care. The fourth hypothesis (proved) is: Head nurses have a form for reporting unusual/abnormal situations available. The fifth hypothesis (proved) is: Patients/clients have questionnaires available to express satisfaction with the care. The sixth hypothesis (proved) is: Corrective measures are taken at wards, on the grounds of patients/clients´ satisfaction with care. The seventh hypothesis (proved): Head nurses participate in preparation of nursing care standards. The eighth hypothesis (not proved) is: Head nurses engage nurses with advanced education in preparation of the standards. The results proved that only those nurses are engaged, who display interest, regardless of their education. The ninth hypothesis (proved) is: Nursing care provided at individual wards has a form of nursing process. Neither nursing process nor nursing documentation is used in one hospital only. The results of the survey will be provided to staff-nurses of the hospitals as a background for continuous quality improvement of provided care.

Support employment for handicapped groups of persons at the work market in the Jindřichův Hradec
MRÁZOVÁ, Ivana
The theme of the thesis is support employment for people in disadvantaged groups. The objectives set in the paper were to assess the quality of services in support employment provided by public corporation MESADA in Jindřichův Hradec, Czech Republic and provide a list of suggested socio-technical recommendations in order to improve the above-mentioned services. The theoretical part includes the history of support employment, definitions of disadvantaged groups of people, symbols, standards, and the whole process of support employment. The final part gives a review of MESADA projects. The practical part deals with a survey. Conclusions of the thesis are based on the quantitative survey {--} the data were collected from questionnaires filled in by users of the support employment services provided by public corporation MESADA Jindřichův Hradec between November 2007 and late February 2008. Next, the author used the document analysis method. Statitistical data were gathered from Czech Statistical Office and statistical data collected by the Ministry of Labour and Social Affairs. The hypotheses that were put forward in order to find out whether the service users find this worthful and quality and whether this service meets their needs were proven correct. The outcome of the survey and the list of suggested measures to be taken in order to improve the service might be found useful in optimizing the support employment service provided not only by p.c. MESADA Jindřichův Hradec, but also in its other branches in the region of South Bohemia.

The contentment with nursing care at children´s department from the view of a person accomplanying the child
MRÁZOVÁ, Iveta
Satisfaction monitoring is one of the indicators of quality of provided care. The quality of nursing care provided in hospitals has been largely discussed recently. For many health care facilities the patients´ opinion is crucial for the nursing care evaluation and represents a feedback for the nursing staff. The objective of my thesis was to examine opinions of persons accompanying child patients in hospital on the nursing care quality. I set three hypotheses: The first hypothesis is {--} persons accompanying child patients in hospital are satisfied with the care, the second states {--} persons accompanying child patients in hospital are satisfied with communication with the nursing staff in a paediatric ward and the third hypothesis suggests that persons accompanying child patients in hospital are not satisfied with the paediatric ward equipment. The research sample was formed by persons accompanying child patients in the Český Krumlov hospital,Inc. Those persons were staying is hospital together with children during their hospitalization. The research was conducted in the paediatric ward of the Český Krumlov hospital,Inc. by the questionnaire method. The research took place in January, February and March. I analysed data obtained from 69 filled in questionnaires. The data analysis shows that persons accompanying children in hospital were satisfied with the care provided {--} the hypotesis I is confirmed. The persons accompanying children in hospital were also satisfied with communication {--} the hypothesis II is confirmed, and they were satisfied with the paediatric ward equipment {--} the hypothesis III isn´t confirmed. The results of my research will be given over to the Český Krumlov hospital, Inc. management, primarily to the Chief Nursing Officer of the Hospital, to the Chief Physician and to the Senior Nurse Manager of the paediatrical ward. The results may serve as a feedback and an expression of respect for the quality of nursing care in the paediatric ward in the hospital Český Krumlov,Inc.
