Energy sensitive X-ray radiography for the non-destructive inspection of historical paintings
Žemlička, J. ; Jakůbek, J. ; Hradil, David ; Hradilová, J. ; Kroupa, M. ; Mislerová, H.
The technical composition of painted artworks is usually very complex and they belong to the most sophisticated cultural heritage artefacts. In the field of their inspection there is a rising demand for the non-destructive imaging and analytical methods which are able to reveal the inner composition of investigated objects. Several non-invasive methods based on the interaction of ionizing radiation with the matter have been successfully utilized during the last decades. These methods can be divided into two main groups. The better known are transmission methods (e.g. classical X-ray radiography) the less-used are emission methods (e.g. X-ray fluorescence imaging). The quality of the obtained image is highly dependent on the imaging characteristics of the used detector. The presently used ones (CCD cameras and CMOS sensors) create the image from analogue signal by the charge integration. This image is usually degraded by the presence of noise. This complication is exceeded by novel pixel detectors of Medipix family based on single particle digital counting. Furthermore these devices offer very high contrast (in principle unlimited) in the obtained image. The image can be acquired with spatial resolution better than one micrometer. Another advantage of these detectors is their ability to directly measure the energy of incident particles. This feature can be used for energy sensitive X-ray radiography (i.e. multi-channel images) and X-ray fluorescence mapping of the surface elemental composition. For the purposes of this work the laboratory ALMA in Prague prepared several multilayer samples of paints using different pigments. The results of mentioned methods applied on the test samples are summarized in this article. The first goal of these measurements is to build a comprehensive methodology for the application of these procedures in the laboratory.

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.

Charity Projects of Organizations Providing Care for Children with Disabilities in South Bohemia
LANDOVÁ, Lenka
The bachelor thesis "Charity Projects of Organisations Providing Care for Children with Health Disability in the Region of South Bohemia" deals with those projects that were founded by non-profit organisations and that provide care for children with health disability in the Region of South Bohemia. The aim of this thesis is to chart the charity projects of above mentioned organisations and to find out what is a proper and effective way to create them and what methods and procedures are used by non-state, non-profit organisations. The first research inquiry refers to a successful implementation of these projects. The result will be not only a realisation what kind of projetcs were created by the above mentioned organisations but also what is important for an organisation itself. Within the bounds of the second research inquiry I find out wheather there is an optimal procedure for the implementation of the charity projects of non-state, non-profit organisations. A qualitative method was used for a research part of this thesis. I used a method of a half-structured interview, a technique of a personal interview. A research group was selected for bringing the research into practice, which includes nine organisations seleceted from non-state, non-profit organisations providing a care for health disabled children in the Region of South Bohemia. It is more difficult for non-state, non-profit organisations it this field to obtain enough finances for providing services and for obtaining necessary aids than for state non-profit organisations because of different ways of fundraising . A non-state, non-profit organisation has several possibilities how to obtain necessary material and non-material sources. There are charity projects that offer means of selfless help; provided they are successful, they help the organisation to obtain necessary sources. It emerged from the research that it was very important for non-state, non-profit organisations to get a multi-source fundraising and supporters of their projects, mainly donors and sponsors, to obtain available care for children with heath disability. On the basis of the research, it is possible to state that non-state, non-profit organisations providing care for children with health disability, implemented many successful projects. The results of this thesis can be used in the way of an informative material for setting a complete view of a solution of the problems of the above mentioned organisations projects.

Support of regional development through the Local Action Group Podchlumí
Jezberová, Zuzana ; Hejnák, Václav (advisor) ; Marcela, Marcela (referee)
The Diploma thesis deals with issues of the support of regional development through the Local Action Group Podchlumí, r.a. (LAG Podchlumí).
The goal of this thesis was to explore the contribution of the LAG Podchlumí to quality of life of residents and business development. Assessment of the influence of LAG on regional development has been based on the existence and implementation of the Program of rural development program of the Czech Republic Axis IV. LEADER, which leads to an improvement of management and to mobilization of the natural inner potential of countryside. The Program of rural development represented the main financial source for fruition of LAG projects in the previous programming period.
In this thesis, activities of the LAG Podchlumí and local subjects for support and development of partnership of residents and for public, business, and non-profit communities have been analysed. Implementation of own projects, through which the versatile development of the region, life improvement of residents, increase the attractiveness of the region has been evaluated. In order to get an independent and objective evaluation, an anonymous questionnaire has been conducted among residents of the region Podchlumí. Further, personal observation of the region Podchlumí, a study of professional literature as well as of internal materials of the LAG has been done. The hypothesis that the Local Action Group Podchlumí plays an important role in development of partnership of public administration of municipalities, agricultural subjects, independent agricultural as well as non-agricultural enterpreneurs, and non-profit organizations has been verified on the basis of analysis of realized activities. Support from the Program of countryside development to the region Podchlumí, Measure IV.1.2 Realization of local development strategy, contributed to achieving improvements in quality of life of residents. The greatest support was given to appearance of communities and quality of infrastructure, development of public facilities and services. Financial resources were spent also on modernization and development of agricultural as well as non-agricultural business. In comparison with other LAGs in the district Jičín, the LAG Podchlumí supported the greatest number of projects through the measure IV.1.2 of the Rural development program on realization of local developing strategy. It has been found by means of evaluation of the anonymous questionaire among residents of the region that residents perceive improvement of appearance and life of communities but they are not aware of the fact that many projects have been implemented with the contribution of activities of the LAG Podchlumí. For this reason, the LAG Podchlumí should focus more on propagation of its own activities. Residents of the region are interested in surrounding of their villages.
It is possible to made conclusion that the results of analysis of activities of the LAG authenticated and confirmed correctness of the hypothesis that the Local Action Group Podchlumí plays an important role in development of partnership of public administration of municipalities, agricultural subjects, independent agricultural as well as non-agricultural enterpreneurs, and non-profit organizations.

Hereditary and non-hereditary factors affecting the quality of rapeseed oil
Zemanová, Kateřina ; Sedláková, Vladimíra (advisor) ; Bečka, David (referee)
This literature review study quality of rapeseed oil in details, depending on heritable and non-heritable factors. Consumption of rapeseed oil is growing every year and in addition to use in human nutrition is also used in animal feed industry or as fuel for motor vehicles. The rapeseed oil has especially a large representation of oleic acid. Furthermore, it is linoleic acid and linolenic acid and undesirable erucic acid, whose quantity is considerably reduced. It is important to mention glucosinolate content, as antinutritional substances, which is reduced together with erucid acid which is known as "00" rapeseed oil. All these components are described in details in this review. The content of fatty acids in rapeseed oil may be influenced both genetic factors and environmental factors. Selection plays a significant role in breeding. Suitably selecting the correct genotypes along with environmental influences can reach the desired target. An important role is played by the synthesis of fatty acids, where in using a desaturation enzymes of fad series, there is desaturation of stearic acid to oleic acid, linoleic acid and linolenic acid. With QTL method, it can be detected genetic background of quantitative traits. Major genes responsible for the quality of rapeseed oil are located on the chromosome A, namely A1, A3, A5 and A8, which are mentioned in the work.

Bayesian classification of digital images by web application
Talich, M. ; Böhm, O. ; Soukup, Lubomír
The contribution introduces web application for image classification that has been developed at the Research Institute of Geodesy, Topography and Cartography in the framework of grant project InGeoCalc (supported by Ministry of education of the Czech Republic). The web application is aimed to display, examine and classify digital image data. The data are expected to be obtained from Internet by means of Web Map Services (WMS) or from other sources (possibly non-registered). Image data from different sources can be combined and presented as composition of layers (coverage) with adjustable degrees of transparency. After gathering the data, Bayesian (supervised) classification is applied to distinguish separate regions in the image. User can choose between several classification methods and adjust pertinent parameters. Furthermore, several subsequent basic analytical tools are offered, namely computation of distances, areas or perimeters related to the classified regions, simple statistical summaries about classification results (e.g. distribution of classes, percentage of non-classified regions, etc.). The classification results and registration parameters can be saved for further use. The web application is based on common Internet standards (HTML, Javascript, SVG). The only requirement for running the application is an up-to-date Internet browser supporting SVG (Scalable Vector Graphics). Typical usage of the web application can involve land cover mapping based on satellite or aerial images. The application is available free of charge for any Internet user.

Differences in CO2 Extraction of Vegetable Oils, Essential Oils, and Minor Components from Plants
Sovová, Helena
Significant progress in understanding the phenomena that control supercritical fluid extraction from plants was made in the last years and is reflected in the literature. Combination of chemical engineering approach and botanical knowledge has appeared to be fruitful for the choice of extraction model and even for the prediction of extraction kinetics. This contribution refers to the papers utilizing knowledge of plant microstructure and location of extracted substances together with extraction equilibrium and attempts to specify the differences among extraction kinetics of vegetable oils, essential oils, and other substances. The most abundant substances like vegetable oils in seeds can be regarded in first approximation as non-interacting with plant matrix, in contrast to the minor components whose equilibrium concentration in CO2 is affected by their adsorption on matrix and often also by co-extracted substances.

Values of live in nursing process
KRISLOVÁ, Anna
This work is aimed at the life priorities of a patient within the context of nursing. The research is focused on the ideas of general nurses of the preferred life priorities of a patient, if there are differences in the ideas of general nurses and the preferred life priorities of a patient, if general nurses take interest in the life priorities of a patient and if they include the work with life priorities within the nursing process. In order to do the research, the method of quantitative collection of data was used, with the aid of the questionnaire technique. Two questionnaires were formed. The first questionnaire, of my own making, for general nurses was distributed among nurses working in hospitals in the area of the city of Plzeň. The other questionnaire, of my own making, for patients was distributed among patients hospitalized or visiting particular departments in hospitals in the area of the city of Plzeň. The research was carried out with the approval of the head nurse. Four aims of this Bachelor's Thesis were stated. The first one aims at assessment of nurses' ideas of the life priorities of a patient and if they consider these an important part of the nursing process. The second aim deals with the question if general nurses are willing to include the work with the patient's life priorities within the nursing process. The third one focuses on the conditions that general nurses have in order to include the life priorities of a patient within the nursing process. The fourth aim deals with the differences between the life priorities preferred by patients and ideas of general nurses of patients' life priorities. General nurses mostly consider life priorities of a patient an important part of the nursing process and most of them are willing to include the work with life priorities of a patient in the nursing process. Patients mostly perceive the care of their life priorities from nurses' side as insufficient. Although illnesses have changed patients' life priorities, some of them could have become unaccomplished, not all general nurses are interested in each patient's life priorities. There have been differences between life priorities preferred by patients and ideas of general nurses of life priorities of patients. The specific theories have been affirmed: T1: General nurses consider working with life priorities of patients as important. T2: General nurses are willing to include the work with life priorities of patients into the nursing process, if certain conditions are granted. T3: Work with patients' life priorities within the nursing process is more frequently influenced by working conditions of general nurses than life priorities preferred by patients. This Bachelor's Thesis may be used when teaching students preparing for the a non-physician medical profession. It may be recommended to general nurses as well as management workers as a tool of increasing the quality of nursing care within psychosocial care.
