Práce na zkrácenou pracovní dobu v SRN: Part-time work in the FRG
Suchomelová, Mirjam
Práce na zkrácenou pracovní dobu (Kurzarbeit) je účinný nástroj, který pomáhá podnikům zvládnout konjunkturální výkyvy a problémy spojené s dočasným výpadkem práce. Místo propouštění mohou zavést práci na zkrácenou pracovní dobu. Část výdělku hradí zaměstnancům v tomto případě Spolková agentura práce (tj. spolkový úřad práce) formou podpory při práci na zkrácenou pracovní dobu (Kurzarbeitergeld). To pomáhá zaměstnavatelům rychle snížit mzdové náklady a zároveň udržet pracovní místa.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Gas exchange characteristics in relation to genotypes in spinach (Spinacia oleracea) under water stress
Helebrantová, Aneta ; Hnilička, František (advisor) ; Pazderů, Kateřina (referee)
The bachelors dissertation was compiled on theme of: Gas exchange characteristics in relation to genotypes in spinach (Spinacia oleracea) under water stress.
Spinach (Spinacia oleracea) is, similarly as the others leaf vegetables, difficult crop in terms of providing the sufficient level of moisture, therefore the attention is drawn to the varieties of spinach which are resistant to the water stress. Thus the target of cultivation is to find plant which will be resistance to influence of the water stress.
In climabox of department of botanics and physiology was founded experiment with three species of spinach: Misano F1, Monores a Matador. The temperature mode was set to 21 °C during the day and 17 °C during the night. The light mode was set to 16 hours of light and 8 hours of dark per day. Maximum light level in climabox was 800 micromole. The plants were cultivated in 4 recurrences, diagram of experiment is involving two variants: control and stress. The plants in control variant were cultivated in substrate, which was irrigated during the whole time of experiment by 250 ml of water. For the plants in stress variant the supply of water was suspended for 10 days and the substrate was naturally continuously dehydrating. After 10 days the water supply was restored (rehydration) for plants in stress variant, same as level of control variant. The observation was made for the speed of gas exchange (photosynthesis and transpiration) in two-day interval. The speed of gas exchange was measured on leaf area with infrared gasometric gas analyzer Lpro+ (ADC Bioscientific, Hodeson, UK). Measured was conducted in morning hours according. Based on the measured values of photosynthesis and transpiration we calculated water usage effectiveness (WUE).
Based on obtained results is evident that the highest average speed of photosynthesis in control variant was observed at variety of Monores (12,10 micromole CO2.m-2.s-1) and lowest at variety Misano (11,58 micromole CO2.m-2.s-1). The highest average speed of photosynthesis in stress variant was measured at variety of Matador (9,43 micromole CO2.m-2.s-1) and lowest at variety Monores (8,76 micromole CO2.m-2.s-1). There was observed decrease of photosynthesis for each of variety during the water stress.
The highest average values of transpiration were observed at variety Monores (1,97 mmol H2O.m-2.s-1), lowest at variety Matador (1,68 mmol H2O.m-2.s-1). Stressed variety Misano reached level of photosynthesis 1,82 mmol H2O.m-2.s-1. Control variety Matador reached speed of transpiration 1,54 mmol H2O.m-2.s-1 and variety Monores 1,85 mmol H2O.m-2.s-1.Variety Misano was on same level of control variant as stress variant.
The most sensitively reacted variety Monores, which usage of water was 4,43 (10-3). Variety Matador managed the stress well, the usage of water was 5,60 (10-3).
Obtained results confirmed hypothesis of genotype differences depending on water deficit, thus there are differences between gas exchange and WUE in control and stress plants.

Changes of proline concentration and electrolyte leakage in the selected species of the Panicoideae tribe under water deficit.
Nováková, Hana ; Hnilička, František (advisor) ; Václav, Václav (referee)
The theme of this thesis is the impact of water deficit on the concentration of proline and electrolyte leakage from representatives of the Panicoideae tribe. The impact of drought on agricultural production in the environment of the Czech Republic is currently an important issue. The exceptionall dry year of 2014/2015 and the associated water deficit in the soil had an impact mainly on the harvest of wide-row crops, including maize. Representatives of the Panicoideae tribe - sorghum and foxtail millet are the most drought-resistance crops in the world. Sorghum and foxtail millet belong to II. group of cereals like maize. Sorghum and foxtail millet show lower transpiration coefficient than maize, they also tolerates less demanding growing conditions and are more resistant to diseases and pests. They also compete with maize in a wide range of applications. It is therefore appropriate to determine how these crops respond to water deficit during their ontogenetic development. For the purposes of this experiment genotypes originating from conditions of temperate climate were selected, this genotypes have a shorter growing season. A short growing season is an important factor in the timing of the harvest of the late sown crops in our climate.
The aim of the thesis was to determine and evaluate the impact of water deficit on the concentration of proline and electrolyte leakage in selected genotypes of sorghum and foxtail millet and on the basis of the results to select genotypes with high resistance to water deficit. Based on the aims the following hypotheses were set: to determine whether there are differences in the concentration of proline and electrolyte leakage between selected genotypes depending on the effect of water deficit and whether there are differences in these physiological characteristics in response to water deficit between sorghum and foxtail millet. To fulfill the objectives and evaluation the hypothesis was based on the greenhouse experiment with selected genotypes of sorghum and foxtail millet at the Department of Botany and Plant Physiology in the Czech University of Life Sciences Prague.
The experiment included 4 genotypes of the species Sorghum bicolor (L.) Moench. (Sorghum): 1216, 30485, Barnard Red and Ruzrok and one variety of the species Setaria italica (L.) Beauv. (Foxtail millet) Ruberit. A total of 4 variants were designated for the experiment (one control and three under the influence of water deficit in different times). The plants in the control variant were full irrigated throughout the experiment. Variant KS was irrigated for the first 14 days, followed by 10 days without watering and the last 4 days were again irrigated. Plants in variant SK were under the influence of water deficit for the first 10 days of the experiment, then 18 days with watering and the plants in the variant SS were without watering for the first 10 days, for the next 4 days were without watering, then the same pattern was repeated: 10 days without and 4 days with watering. Physiological characteristics were observed in plants in the developmental stages BBCH 14-16. The concentration of proline was determined by measuring the absorbance of the samples formed by the reaction with ninhydrin. Subsequently, the measured values were compared with the calibration curve. To measure the sample absorbance at 520 nm a spectrophotometer Hellios gama (Thermo) was used. Electrolyte leakage on discs made from leafs was measured with electrical conductivity meter GRYF 158 (HB Griffin, Ltd.).
The obtained results show that the proline concentration increased in response to water stress, since the highest concentration of proline was detected in plants growing in the most stressed variant of SS (670.13 micrograms) compared with other variants of stress. Plants variant KS (643.85 micrograms) showed a higher accumulation than the proline in variant SK (636.69 micrograms). The highest concentration of proline was measured on a genotype in the variety of sorghum Ruzrok (642.94 micrograms). The lowest content of proline was found in the variety of sorghum 1216 (623.78 micrograms), this value was also the only significant difference from the contents of proline to other genotypes. Which at least partly confirms the proposed hypothesis that there are differences in the content of proline between genotypes.
The highest electrolyte leakage cell damage was respectively exhibited in plants from the variant SS (39.56%). Plants of the SK variant showed a higher rate of cell damage (32.95%) than plants from the variant KS (29.88%). The lowest cell damage was exhibited in plants grown under control conditions, which again indicates that damage cells increases in response to water deficit. In this experiment the highest degree of cell damage was found in the variety of sorghum 1216 (29.26%) and lowest cell damage was observed in the variety of sorghum Ruzrok (27.03%). A significant different degree of cell damage appeared only in the variety foxtail millet Ruberit (28.6%), which confirms our hypothesis that there are differences in the electrolyte leakage between sorghum and foxtail millet.
The hypotheses were not fully confirmed by the experiment. Nevertheless, on the basis of obtained results we conclude that the least drought-resistance genotype is the 1216 variety and the best adapted to the water deficit was the Ruzrok variety. It also confirmed that the higher proline accumulation may protect the plant against the negative effects of water deficit on the cell membranes, which is then reflected in a reduced electrolyte leakage.

ABO incompatibility in hematopoietic stem cell transplantation
PECHMANOVÁ, Alena
ABO incompatibility between the recipient and the donor is not a barrier for successful haematopoietic stem cell transplantation. Even though it is the HLA compatibility that has a major impact on engraftment, ABO incompatibility may cause a number of complications, e.g. both immediate and delayed haemolytic reaction, pure red cell aplasia and a higher level of GvHD. In my Bachelor's thesis, I investigated the influence of ABO incompatibility and the level of the initial titer of isoagglutinins on the red blood cell engraftment time, on the time of the complete transition to the donor erythropoiesis and on the number of transfused red blood cell products. I followed 104 patients who underwent haematopoietic stem cell transplantation. I divided the patients into four groups according to the ABO mismatch type (major, minor, bidirectional) or ABO match with the donor. In patients after transplantation, the blood group was repeatedly examined using the micro-column gel technique, which enables us to distinguish the dual population of donor and recipient derived erythrocytes, if they differ in the ABO or RhD antigens. The analysis revealed a statistically significant delayed red blood cell engraftment in patients with major mismatch caused by the destruction of newly forming precursors of the erythrocytes of the donor by anti-A, anti-B antibodies in the blood of the recipient. Neither prolongation of the time to complete transition to the erythropoiesis of the donor nor increased requirement of red blood cell products in this period of time were statistically significant in the case of major mismatch. There was no impact of the level of the initial titer of isoagglutinins on the monitored parameters in the examined patients. Foreign medical literature provides new findings based on which, after a consultation with physicians at the Transfusion Department, we agreed to change the ABO group of plasma products transfused to patients with minor and bidirectional mismatch after the transition to the erythropoiesis of the donor.

The Issue of Placement of Seniors in Homes for the Elderly
VANČUROVÁ, Alena
The thesis deals with problems connected with the placement of senior citizens into homes for the elderly. The objectives of the thesis are to find out how long the waiting period for the placement into a home for senior citizens is and which obstacles and problems connected with the placement into homes for the elderly appear. The theoretical part of the thesis is focused on some demographic trends, the opinion of the Czech population about the old age and senior citizens, history of social services for senior citizens in the Czech Republic and abroad, and the current offer of social services for senior citizens. In this part, I also describe the process of placing of senior citizens into homes for the elderly and the services which homes for the elderly offer to their clients; I also focus on the senior citizens´ financial reimbursement of board and lodging in homes for the elderly. The research was conducted by means of quantitative and qualitative methods and techniques. In the qualitative research, I deal with the second part of my goal identifying obstacles to placement in homes for the elderly. Firstly, I set the following research questions: 1) What are the obstacles and problems in the process of placing senior citizens into homes for the elderly? and 2) Do senior citizens have any other options of care instead of the care in homes for the elderly? Then, I conducted semi-standardized interviews with 3 social workers, 8 senior citizens and with 3 members of families which put their senior citizens into homes for the elderly. I asked all of them almost identical questions to be able to compare their responses later. The results show that nowadays, dependent senior citizens who have no other option of care are more likely to be placed into homes for the elderly. The answers to the question "What are the obstacles and problems when placing senior citizens into homes for the elderly?" were rather variable and they cannot be generalized. The quantitative part of my research relates to the first part of my goal. Here I primarily focused on the waiting period. The following two hypotheses were set for the research. H1: Senior citizens negatively evaluate the waiting period for their placement into homes for the elderly. H2: Senior citizens know only one possibility of care homes for the elderly. To verify the above hypotheses, I used the method of secondary analysis of the data taken from the client's documentation and the method of controlled conversation. Therefore, I conducted my research in the following homes for the elderly: Home for the elderly Light in Písek, Home for the elderly Bechyně, Home for the elderly Diaconia Centre ČCE Blanka in Písek, Home for the elderly Centre for Social Assistance Vodňany. Social workers in each facility advised me to use the greatest possible number of clients who were oriented and able to answer my questions. In total, I analyzed 100 files of personal documentation and then I conducted the structured interviews with the analysed clients in the homes for the elderly which are mentioned above. The average waiting period was 243 days. In the category of the waiting period shorter than 1 month there were 26 senior citizens; from 1 to 2 months 33 senior citizens; from 3 to 4 months 11 senior citizens; longer than 5 months 30 senior citizens. 79 senior citizens rated their waiting periods positively, but 21 senior citizens rated their waiting periods negatively. 56 senior citizens had some knowledge about other possibilities of care; most of them reported the nursing service (54 responses); homes with nursing (8 responses); personal assistance (3 responses); pensions for senior citizens (1 response).

Social Exclusion at Senior Homes
STEJSKALOVÁ, Martina
This thesis deals with the social exclusion of senior citizens living in retirement homes. Each year there is an increase in the number of senior citizens which results in larger necessity of social services of live-in facilities. These facilities provide senior citizens with complex care incl. accommodation and board. In these facilities certain factors can occur that could deepen social exclusion. The risk of social exclusion is going up if the autonomy of senior citizens is being restricted and their vital human needs are not respected. In the area of live-in services it is crucial to view every senior citizen as a unique human being in the bio-psycho-socio-spiritual context and tailor the care to their specific needs. The theoretical part of the thesis focuses on objectification of the terms which are based on technical literature and are important for understanding the mentioned issues as well. The chapters address the issues of the ageing process and the old age, periodization of the old age, distinctive changes in the old age, autonomy in relation to the old age, social services for senior citizens in the legislative framework with detailed focus on retirement homes, social exclusion and economic, political and social dimension with regard to the old age. The last chapter of the theoretical part aims at the retirement home in which the research survey has been conducted. At the request of the management of the retirement home and with respect to the ethical aspects of the survey the name of the facility is not stated in this thesis, however, the name Retirement home XY is used. The goal of the empirical part of this thesis is to map the factors which influence social exclusion of senior citizens in the chosen retirement home. The empirical part is then focused on finding the answer to the main research question. Three partial research questions have been determined in order to answer the main research question. For obtaining the necessary data the strategy of qualitative research a surveying method including the technique of semi-structured interview has been selected. The semi-structured interview has been carried out with nine inhabitants of the Retirement home XY who have been chosen on the basis of criteria of quota intentional selection. Quotas for research surveys have been set as follows: The resident of the Retirement home XY who has lived there for the time period of at least 24 months, the resident of the Retirement home XY who draws care allowance in the I. or II. level and the willingness to cooperate. The gained data have been evaluated by the method of creation of clusters, namely on the grounds of the common traits/features. The final data is introduced in compliance with the particular partial research questions. As emerged from the research, communication partners with movement difficulties do not have any contact with the surrounding environment. There is a lack of walks in the neighborhood. It has also been discovered that there is a shortage of excursions. Communication partners see more leisure time. Furthermore, the research has shown that the amount of contact with the immediate family and extended family has decreased. In the area of finance they do not see any considerable changes though some communication partners cannot afford to pay for the whole stay. They seem to be content with the board, after the chef has been changed, only some communication partners would welcome to have their dinner at a later time. Out of means of transport they make use of ambulance car predominantly. They feel neither need to transport themselves anywhere nor run errands. They appreciate the availability of health care, however, a wish has emerged that the general practitioner would visit the Retirement home XY at least twice a week. The results of the empirical part serve as feedback for the management of the Retirement home XY and can contribute to the improvement of the quality of the provided services.
