Guide dog as a Helper for Disabled People
Jirková, Tereza ; Dočkal, Jan (advisor) ; Hubertová, Lucie (referee)
This work consists of four parts. First of all, it deals with human needs. According to five disablement types, it focuses on the needs and possibilities of communication, self-care, spatial orientation and independent movement. The second part called "A Man and a Dog" introduces their coexistence from the past up to the present and describes how and with what a dog can help a disabled person. It describes individual kinds of service dogs and specific ways to help mitigate the impacts of disablement. It provides information on which breeds are suitable for training and describes the dog training from choosing the puppy up to its integration into the life of the user. The third part shows individual social aspects related to the purchase of a dog, demands, positives and negatives of owning a service dog. It analyses the legislative concerning the problems of assistance animals and suggests its improvement. It shows the financial problems of special dog training in this country and abroad. It also gives information on myths which are in the eyes of the uninformed public connected with the training of these dogs and analyses the current channels raising awareness of these problems. In conclusion, two casuistries are included as well as an evaluation of ten semi-structured dialogues of the service dogs owners,...

Development of dispersive liquid-liquid microextraction coupled with capillary liquid chromatography for determination of fipronil and its two metabolites
Jirková, Tereza ; Nováková, Lucie (advisor) ; Horstkotte, Burkhard (referee)
1 ABSTRACT Charles University, Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Tereza Jirková Supervisors: Dr. Francisco J. Lara prof. PharmDr. Lucie Nováková, Ph.D Title: Development of dispersive liquid-liquid microextraction coupled with capillary liquid chromatography for determination of fipronil and its two metabolites Fipronil is a phenylpyrazolic insecticide that is prohibited for use in food-producing animals. This diploma thesis proposes a green analytical methodology for the study of residual fipronil and its two degradation products, fipronil sulfone and fipronil sulfide. For their determination, a method of capillary liquid chromatography with UV detection was developed and validated. Correlation coefficients above 0.998 confirm good linearity and the study of repeatability with values not exceeding 2.9% RSD shows high precision of this method. For the dispersive liquid-liquid microextraction method used for sample preparation, the dispersing and extracting solvents were optimized. The results show that the highest recoveries 82% - 92% were achieved with dibromomethane as an extractant and acetonitrile as a dispersant. All the experiments were carried out with standard solutions and in further studies this methodology should be transferred to egg or other...

Bioaktivní látky ve výživě člověka
Jirková, Tereza
This bachelor thesis was focused on studying the literature on the selected topic and on the distribution of individual groups of substances and their effects on human health. The thesis mainly focused on the influence of human nutrition on ones health. In the practical part of the work, there were evaluated selected types of fruits and vegetables, as to which are the most beneficial for end consumers rated by their ascorbic acid and polyphenols content. The highest concentration of ascorbic acid was measured in rosehips and chilli peppers. Fairly high content of ascorbic acid and polyphenols was found in pomegranate juice and rosehips. In terms of the content of those health-beneficial substances, it was found that the most beneficial are rosehips and pomegranate juice. In this work, there were created calibration charts and tables with ascorbic acid and polyphenols content in selected fruits and vegetables.
