Complexes of macrocyclic ligands
Buziková, Michaela ; Hermann, Petr (advisor) ; Vojtíšek, Pavel (referee)
Macrocyclic ligands are compounds well-known and studied for their ability to bind metal ions into complexes possessing high kinetic inertness and thermodynamic stability. These properties make such compounds useful in medicine. This thesis focuses on ligand cis- DO2A2P, which belongs to a series of ligands based on cyclen skeleton with mixed acetate and phosphonate pendant arms. A lot of attention has been paid to the other members of this ligands series, but the information about cis-DO2A2P is still incomplete. In this thesis, the complexation properties of mentioned ligand were studied, as well as properties of its complexes with the lanthanide ions in solution. Key words Macrocycles; polydentate ligands; lanthanides; transition metals; organophosphorus acids

Significance of Philantrophy in community social work focusing on efficiency of performance
Sittová, Kateřina ; Vojtíšek, Petr (advisor) ; Šťastná, Jaroslava (referee)
Significance of Philanthropy in community social work focusing on efficiency of performance Abstract (in English) The aim of this diploma thesis is the presentation of the subject of philanthropy in community social work. Special attention is however paid to the concept of effectivity of performance of social work. It is also endeavoured to delineate the concepts such as community social work, philathropy, quality of social services and measuring social impact. The main purpose of the research part of the thesis is exploration of the question whether there is a connection between effectivity of an organization and its success. In the commercial sector, success is perceived as long-term stability of the organization and its market prosperity. The aim of the research was to find out if this relationship holds true for non-profit sector or social services as well. The chosen strategy was qualitative research. The data collecting was conducted by means of individual semi-structured interviews. The main contribution of the thesis is the finding that the performance capacity of an organization is conditioned primarily by its staffing. More precisely, the more high-quality employes the organization has the higher performace it should achieve.

Ligands for Multifunctional Dinuclear Complexes
Králová, Marie ; Vojtíšek, Pavel (advisor) ; Lukeš, Ivan (referee)
Title: Ligands for Multifunctional Dinuclear Complexes Author: Marie Králová Site: Charles University in Prague, Faculty of Science Supervisor: doc. RNDr. Pavel Vojtíšek, CSc. Abstract The aim of this work was to prepare substitued phenols as ligands for binuclear complexes of copper(II), which could be used as anion receptors. Two main sythethic strategies are summarised in the introduction: First is single step Mannich-type reaction of 4-substitued phenol, paraformaldehyde and secondary amine, other includes preparation of substitued bis(halomethy)phenol and it's following reaction with secondary anime. A single step Mannich-type reaction was used for preparations of following known ligands: 2,6-bis[(N-methyl piperazine-1-yl)methyl]-4-formyl phenol (L1), 2,6-bis[(N- methyl piperazine-1-yl)methyl]-4-nitro phenol (L3) and 2,6-bis[(N-phenyl piperazine-1- yl)methyl]-4-nitro phenol (L4). The new ligand, 2,6-bis[(N-phenyl piperazine-1-yl)methyl]- 4-formyl phenol (L2), was prepared in the same way. A structure of this ligand was determined using X-ray. One Pd(II) complex [PdL2Cl2]·1.5MeCN (K3) was prepared and it's structure was determined. UV-VIS spectroscopy was used to study interactions in ligand - metal and ligand - metal - anion systems in order to determine the anion - binding capabilities of the...

Using of coaching in social work.
Novotná, Lucie ; Vojtíšek, Petr (advisor) ; Šťastná, Jaroslava (referee)
(anglicky): The bachelor thesis deals with the phenomenon of coaching and its possibilities for using in social work. All the work is focused only on the micro level of social work, so it is working with methods of working with the individual. The thesis consists of a theoretical part, which mainly defines concepts directly related to the topic. Then their similarity is compared in accordance with chapters before. The second part - the practical part - was go through with interviews with the coaching respondents, the social work respondents and the respondents, both of whom meet these themes. Respondents were asked questions in the wording that corresponds to their work, that questions for respondents in the field of coaches had a modified wording, so they would ask about the essence of working with the client in coaching. Similarly, for the respondents in the field of social work the wording of the questions was adapted. Based on the evaluation of these interviews, not only the similarity of the two areas was confirmed but also the conditions under which coaching in social work could be used. Klíčová slova (anglicky): social work, case work, coaching, social worker, coach, client

Evaluation of selected low-threshold children and youth facilities
Marková, Anna ; Dragomirecká, Eva (advisor) ; Vojtíšek, Petr (referee)
(in English): This diploma thesis deals with the theme of low-threshold facilities for children and youth. The thesis is divided into a theoretical and empirical part. At the beginning of the theoretical work, work with risky youth, the theory of risky behavior and its individual types is approached. In detail, a low-threshold facility for children and young people is introduced, including legislative anchoring, principles, target group and individual working methods. At the end of the theoretical part is described system of social services assessment and current events in this area. The empirical part contains research methodology, research results and evaluation. The aim of the thesis is to compare the facilities of the capital city of Prague and the Central Bohemian region and to compare the ideas about the goals of work between the managers and their subordinates. A qualitative method was chosen for the research, when data collection was carried out using semi-structured interviews.

Coordination Compounds as Contrast Agents for 19F-MRI
Špánek, Jiří ; Kotek, Jan (advisor) ; Vojtíšek, Pavel (referee)
Magnetic Resonance Imaging (MRI) is one of noninvasive imaging and diagnostic methods in today's medicine. The most commonly measured nucleus is H1 of the water molecules present in the human body. There are also methods that use signal saturation transfer between the contrast agent and water molecules via exchangeable H1 nuclei, or use a different nucleus like F19 . Compounds that show a high potential in this area are complexes of paramagnetic ions such as Gd3+ , Eu3+ , Co2+ , Cu2+ and Ni2+ , which can affect relaxation times and chemical shifts of other atoms due to their magnetic properties. This Master's thesis focuses on ligands L1 and L2 which were prepared in the Bachelor thesis. The main focus is on preparation of complexes with selected paramagnetic ions and subsequent study of their properties relevant for a potential use as contrast agents for F19 -MRI and CEST methods. Keywords: F19 -MRI, CEST, macrocyclic ligands, coordination chemistry

Influence of the social workers organisations on the legislative process
Bílá, Veronika ; Vojtíšek, Petr (advisor) ; Zajacová, Melanie (referee)
Vliv organizací sociálních pracovníků na vývoj legislativy Bílá This research investigates the influence of social work organizations on the legislative process. The goal is to describe the legislative process and find out if the organizations aim to influence it. And if that is the case, what approach they are using. The aim was to map their effort on two different laws; The laws I chose are the Social Service act and the Professional law. Conducting this research, one finding was that social work organizations attempted the influence of the legislative process in both cases. But, the amount of activity was based on the will of law makers induction of social work organizations into the law making process. The type of activity chosen to influence the process varied based on the stage of the process.
