Plasma hydrogenation of hydrothermally grown ZnO micropods
Remeš, Zdeněk ; Aubrechtová Dragounová, Kateřina ; Mičová, J.
The hydrothermally grown ZnO micropods have been placed on grounded stainless-steel holder and exposed to an inductively coupled plasma (ICP) monitored in-situ by optical emission spectroscopy (OES). OES shows the immediate release of oxygen during Ar ion bombardment. The prolonged exposure to hydrogen plasma leads to deterioration of the optical properties as well. The exposure, rf power and hydrogen pressure have been optimized to enhance UV-photoluminescence peak at the wavelength 384 nm related to surface bounded excitons and reduce the defect-related photoluminescence in red spectral range. The strong UV photoluminescence appears just after 1 minute of plasma hydrogenation in a radio frequency plasma discharge with power density 40 W/dm3 and hydrogen pressure 17 Pa.

Supervision in the Helping Professions
AUBRECHTOVÁ, Kateřina
In Czech literature, supervision is usually referred to as inspection or overview. Certain authors claim that supervision would not be supervision without either of them. Supervision provides an overview, which is important in solving occupational issues and monitoring the workers' quality and professionalism. The theoretical section explains the basic terms that are related to the title of the essay. It explains the word supervision, auxiliary professions, supervision and its forms, objectives, methods and a supervision contract. The text also specifies who can submit supervision, which criteria the supervisor must fulfil and the relation between the supervisor and the supervised. The essay determines supervising methods (and techniques) used in selected institutions and reveals whether and how the supervisor allows for typology of the clients with whom the institution works. It also ascertains how the supervised persons perceive the supervisors. I specified three research issues: 1. What does supervision give to the supervised? 2. Do the supervisors apply different supervising methods according to the client's typology? 3. Does the supervisor heed typology of clients that are a target group of the given institution? In the practical section of the essay, I applied a form of qualitative research with regard to the specified objectives. For collection of data, I used a research method based on queries and an associated research method of semi-structured interviews. I appended the queries with an observation method. Eighteen persons participated in the interviews. Fifteen of the supervised persons came from three different institutions (a Charity Home for Mothers with Children, a Nursing Home in Havlíčkův Brod and an Institute of Social Care in Zboží) and three persons were supervisors, one from each institution. The essay may help to improve knowledge of persons with auxiliary professions on the supervision and facilitate supervision in various institutions with regard to the clients' typologies.

Educational program for parents about violance commited on children
AUBRECHTOVÁ, Kateřina
Violence committed against children, especially physical maltreatment, abuse and neglect, is a theme which has recently been covered by media reports more and more often. It is a sad thing that in spite of a big amount of reported cases there is a lot of other ones which remain hidden behind the private household walls. Physical maltreatment, abusing and neglecting children is a very grave and interesting topic at the same time. I started being interested in it already at the secondary school. That is the reason why I have chosen this topic for my final bachelor thesis. The theoretical part focuses on family and child and their position in society. In this thesis we can find types of maltreatment, abusing and neglecting described. Further on we are getting to know the text characteristics, after - effects, victims and perpetrators of each kind of maltreatment. The aim of this work is to find problematic areas of violence committed against children where parents do not have enough information yet. The research was carried out using written questionnaire forms. These ones were handed out to parents of children attending 1st to 4th classes of elementary schools in Sazavka and Habry. In my thesis, three hypotheses have been set. The first one implies that the foreknowledge of the patents is closely connected with their age. This hypothesis has not been confirmed. The second one implies that the foreknowledge of the patents is closely connected with their education. This hypothesis has not been proved either. The last one implies that the parent who is informed should know at least one example of four essential types of maltreatnent. This hypothesis has been confirmed by the obtained results. According to answers, 87 % of parents have information on physical maltreatment, 86 % parents on psychical maltreatment, 74 % on sexual maltreatment and 33 % of parents know neglecting. On the basis of the obtained results it will be possible to make an educational programme for parents in the field of violence committed against children.
