High - school bullying
FRIEDLOVÁ, Barbora
This bachelor thesis deals with bullying in secondary schools and its issues. My thesis focuses on the knowledge of high school students regarding bullying and also prevention. The first part of my bachelor thesis is theoretical. The theoretical part is dedicated to bullying, where bullying is described as a concept, then the stages of bullying and its forms are described. In the next chapter I define who is a participant of bullying, as a victim and aggressor, what are the consequences of bullying for the participants. I also deal with prevention. In the second part I describe my own research. The aim of my bachelor's thesis was to describe how high school students perceive the issue of bullying, then the sub-objectives were to find out what the manifestations of bullying are according to the students, whether they know any prevention programs and what knowledge they have about bullying. Qualitative research was chosen to meet the objective. The research method is questioning, and the technique is semi-structured interview with nine communication partners. Open coding method was used to evaluate the data that was collected during the research. In order to achieve the predetermined objectives, I used four research questions: What knowledge about bullying do high school students have?; What are the manifestations of bullying according to high school students?; What anti-bullying programs do high school students know?; Have high school students ever encountered bullying? The research showed that students know what bullying means and how it manifests itself. Students have an overview of what forms bullying takes. Some students have personally experienced bullying as witnesses. Students have mostly encountered prevention programmes in school lectures. For most students, prevention is provided in their schools and bullying does not occur.

Critical Points in Teaching German
MAREŠOVÁ, Anna
This diploma thesis deals with critical points of German language teaching in primary and secondary schools. The first part of the thesis is focused on the researched issues from a theoretical point of view and presents the foreign languages didactics. It further describes the German language framework educational program and related concepts that can help to understand and facilitate the solution of critical points in German language teaching. The second part presents the evaluation and analysis of 25 questionnaires obtained from the IPUP KA7 project (Innovation of teacher training for practice, CZ.02.3.68 / 0.0 / 0.0 / 16_038 / 0006960). This survey was focused on the identification of critical points from the perspective of German language teachers at primary and secondary schools. Four of these critical points are analyzed in more detail and accompanied by motivational exercises that can simplify them for teachers and students as well.

Kinetic determination of nitrites with spectrophotometric detection
Vašíčková, Pavla ; Nesměrák, Karel (advisor) ; Rychlovský, Petr (referee)
Title: Kinetic determination of nitrites with spectrophotometric detection Annotation: The proposal and optimization of the kinetic determination of nitrites in water samples is the aim of this bachelor thesis. The method is based on the ability of nitrites to catalyze the oxidation of toluidine blue by bromate in acidic media. The course of the reaction is monitored by spectrophotometrically, using a decrease of the absorbance band at 653 nm in the constant period of time from the beginning of the reaction. The dual-chanel manifolds FIA apparatus was proposed and optimized. The calibration dependency in the range of 0,05-1,00 mg ml-1 was measured. The instrumental limit of detection of 0,038 mg ml-1 and limit of quantification of 0,125 mg ml-1 were calculated. The method was applied on real sample of river water. Key words: nitrites, flow-injection analysis, kinetic catalytic methods

Explant cultures of Higher plants 27
Kostřiba, Jan ; Dušková, Jiřina (advisor) ; Tůmová, Lenka (referee)
Kostřiba J.: In vitro cultures of higher plants XXVII. Diploma Paper, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, 2007, p. 61 The work aimed at biotransformation of exogenous precursors of arbutin with in vitro cultures of Centella asiatica (L.). The precursors of arbutin were added into the medium (hydroquinone, tyrosine, p-coumaric acid, hydroxybenzoic acid). The precursors were used in a concentration of 200 mg/l and the period of their action was 6, 12, 24, 48 and 168 hours (1 week). The cultivation of calluses was created by two different ways - by suspension culture and by culture cultivated on the filter-paper bridge. The cultivation was prosecuted on the light. Positive results (both TLC and HPLC analysis) in arbutin production were obtained in all suspension cultures after an addition of hydroquinone. The largest amount of arbutin in callus cultures was measured after a 48 hours cultivation (0,043 %). After a 168 hours cultivation was amount of arbutin only 0,038 %. In this experimental variant arbutin was also released into the medium (0,096 %). Biotransformation experiments with the others precursors of arbutin were not successful. The way of cultivation by the filter-paper bridges was also unsuccessful.

The energy expenditure at critically ill patients
Švrčková, Alexandra ; Hronek, Miloslav (advisor) ; Havel, Eduard (referee)
The aim of this study was to determine energy expenditure and to find relations between resting energy expenditure (REE) and selected parameters in 14 polytraumatic patients in the ICU of University Hospital in Hradec Kralove, which were easily measurable and usable for REE prediction. In this study 7 men (age 36 ± 18 years) and 7 women (age 58 ± 28 years) with polytrauma were examined. The assessment of REE was measured via indirect calorimetry (IC) method. The examination also included bioimpedance analysis (BIA). BIA was useful especially for obtaining values of overhydration (OH), lean tissue mass (LTM) and metabolically active body cell mass (BCM). Average REE-IC (measured by IC) was 2116 ± 516 kcal·day-1 in men and 1450 ± 407 kcal·day-1 in women (P = 0.018). Statistically significant difference between men's and women's population was also found in these relations: calculation of basal energy expenditure according to Harris-Bennedict equation without (P = 0.001) and with deduction of OH from body weight (P = 0.001), at "breathing energy expenditure" (REE related to respiratory rate) (P = 0.018) and at (REE related to heart rate) "heart rate energy expenditure" (P = 0.038). REE-IC related to kilogram of BCM with and without deduction of overhydration was shown as statistically significant...
