Mercury contents in mushrooms growing nearby Horní Slavkov
Říhová, Štěpánka ; Svoboda, Lubomír (advisor) ; Tondl, František (referee)
In the seventies it was discovered, that many species of wild higher fungi accumulates in their fruiting bodies some potentially hazardous elements in amounts significantly higher, than any other ecosystem cells, respectively eatables. For the most risky elements especially cadmium and mercury are considered. The aim of my rigorous paper was to determine mercury content in the fruiting bodies of mushrooms growing in the area with an extremely rich history of mining and processing of metal ores (mostly tin). Mushroom samples were collected (from July 2005 to September 2006) from two sites near the village of Krásno close Horní Slavkov. Mercury was analyzed in 130 samples of 13 edible mushroom species. Only fully developed fruiting bodies were selected for the analysis, each represented a separate sample. It was also carried out a comparative test, detecting effect of fungal cleansing on the kontent of mercury. Mercury was determined in homogenized samples on a single-atomic absorption spectrometer AMA -254, which uses the technique of atomizing cold vapor generation of mercury with subsequent capture on a gold amalgamator. The content of mercury in the fruiting bodies of the monitored area was very well comparable to the normal state in areas without mining. In point of harmful character of mercury,...

The Social Services Staff Access to the Supervision.
ŘÍHOVÁ, Štěpánka
The bachelor thesis is focused on the attitude of social service workers to supervision. The objective of the thesis is to determine the attitude of social service workers to supervision. A partial goal of the work is to determine the benefit of supervision for social service workers. I focused on their experience and evaluation of the attitudes towards the supervision, and also on their reaction to stressful situations and also on how they try to prevent the burnout syndrome. In the theoretical part I focused on three basic chapters: social services and standards of quality, supervision and the burnout syndrome. In the practical part, in the qualitative research I chose ten workers in direct service from the Care House of Mistr Jan Křišťan in the town of Prachatice. I set one main research question:? What is the attitude of social service workers to supervision?? and four partial research questions. I applied the method of qualitative research with the technique of semi-structured interview. The results are assessed in tables. The results revealed that the attitude of social service workers is in nine cases out of ten positive. They see the benefit of supervision in the opportunity to meet together in a pleasant and safe environment and in the opportunity to talk undisturbed about difficult and painful situations coming continuously during the performance of this profession. Supervision for them also means a significant contribution in delivering hope, expression of empathy and respect from the supervisor for their hard work done. The results of the bachelor thesis could be a source of information about supervision, its contribution, development and provision in social services in the region of Prachatice. The thesis could be used not only by social service workers but also by the workers in educational and medical facilities. The thesis could be used for all helping professions.
