Occurrence of mercury in the hair of school children.
HLADÍKOVÁ, Alena
The target of the thesis was to summarize the present knowledge to the topic of occurrence of mercury in hairs of the age categories of respondents defined in advance and to evaluate experimentally the load of the human organism by mercury. It was necessary to acquire a sufficient amount of hairs of children of school-age from the selected locality, to determine the total mercury amount in these samples and to evaluate the achieved results from the viewpoint of the toxic load. Within the bachelor thesis, 90 samples of human hairs of nine various age categories in the range from seven to nineteen years (of respondent age) were tested. In each age category, there were 50% samples of the male and 50% samples of female population. Moreover a questionnaire was made up filled in by each participating person. The determination of the total mercury contents was performed on the one-purpose spectrophotometer AMA-254. Means for the total mercury concentration moved deeply under the permitted limit values. Even the highest established mercury value which was 0,38554 mg/kg was under the limit. Using the one-way ANOVA (F2,87=5,4364; p<0,05) in STATISTICA 7 program, it was proved based on the reviewed influence of factors on the level of mercury in the body, that the mercury concentration depends on the consumption rate of the freshwater fish.

The Turnover of Personal Effects as a Nursing Staff's Problem
PEČENKOVÁ, Ladislava
The Turnover of Personal Effects as a Nursing Staff´s Problem The subject of death is part of life. For nursing staff, a very difficult and psychologically very demanding situation and part of their work is having to onform the next-of-kin that their relative´s life has ended. Conveying such news requires good ethical and communication skills on the part of the nurses. In addition to psychological stress, there are other aspects that have to be dealt with, e.g., communication as such, as well as proprietary and family relation with the next-of-kin. The objective of my research was to identify the problems that nursing staff members encounter when turning personal effects of the deceased over to the next-of-kin. With this objective in mind, I formulated my first hypothesis. The nurses´ primary problem during turnover of personal effects is communication. Secondly, I wanted to find out about the nurses´ preparedness for communication with next-of-kin and for turnover of personal effects. Finally, I wanted to see, whether the nurses needed anything to be able to handle the process adequately. For addressing the latter question, I created a second hypothesis. The nurses´ perception of the process of turnover of personal effects depends on the suitability of the environment. This undergraduate thesis is divided into two parts: a theoretical and a practical one. In the theoretical part, man´s death as well as care for the dying and the dead is described from historical and present-day perspective. Various rituals, legal steps, communication problems, and their effect on nurses are described. A quantitative survey was taken using the technique of hard-copy questiinnaires. The questionnaire was anonymous and contained 34 questions. It was addressed to the nursing staff in oncology, internal medicine, surgery, and geriatric hospital wards, as well as psychiatricasylums and homes for the elderly in the Vysočina and South-Bohemian Regions. The results of my survey refuted the first and confirmed the second hypothesis of mine. The thesis also myps the problems that nurses in these wards encounter most frequently. The nurses´ suggestions can be useful to managements of medical and social institutions seeking practical solutions for facilitating and improving the quality of the process of turning over the personal effects of he deceased.
