Generation of Detergents Effects into Synthetic Fingerprint
Bartoš, Patrik ; Sakin, Martin (referee) ; Kanich, Ondřej (advisor)
This bachelor thesis describes the design and implementation of an application that generates fingerprint damage into images of synthetic fingerprints. The resulting application can generate images of fingerprints affected by selected detergents – desinfection, abrasive soap and solid soap. Prior to the actual implementation of the application, the selected damage types were analyzed on a self-scanned database of fingerprints damaged by these detergents. The implemented algorithms were then used to create several datasets from a synthetic fingerprint database generated by the tool SFinGe. These datasets were then tested using the VeriFinger tool.

Disinfection by-products originating from pesticides
Plachá, Markéta ; Načeradská, Jana (advisor) ; Kopecká, Ivana (referee)
An important step in the treatment of drinking water is disinfection, which serves to remove pathogenic substances. During this process, disinfection by-products can be formed, which are mainly produced from organic natural substances reacting with the disinfectant. However, treated water may also contain anthropogenic substances, such as pesticides, whose disinfection by-products are the subject of this work. From the accessible data of the studies carried out so far, a basic summary of their creation was created, and characteristic properties that are essential for the evaluation of adverse effects on human health and the environment. From the field of organophosphorus pesticides, it was found that pesticides containing a phosphorothioate part can be easily oxidized by chlorine to the corresponding oxone derivative, while organophosphorus pesticides with a phosphate part are very stable in the presence of chlorine. The resulting oxon forms can be more effective inhibitors of acetylcholinesterase than their parent compounds and at the same time be stable enough (more than 24 h) to reach the consumer, on whom they can, however, have a negative effect. At the same time, disinfection by- products from pesticides can be more toxic than the original compounds. These include chloroxon, diazoxon and...

Use of advanced oxidation processes in pool water treatment
Trávníček, Jakub ; Pivoda, Bohuslav (referee) ; Biela, Renata (advisor)
The research part of the thesis is focused on the use of advanced oxidation processes in the treatment of swimming pool waters. In the first part, the common disinfection technologies that are used domestically and abroad for the treatment of swimming pool waters are described. In the second part, the research focuses on the basic types of advanced oxidation processes used in swimming pool facilities and other similar laboratory-scale technologies with potential for future use in the spa industry. The practical focus of the thesis consists of two parts. In the first part, data from a questionnaire of selected swimming pool facilities in the Czech Republic are processed, which summarizes what technologies are used in the treatment of swimming pool waters in the Czech Republic. The second part consists of a case study that analyses the effect on the quality of treated water before and after the installation of advanced oxidation processes system in the pool recirculation circuit.

Nové trendy prevence infekcí spojených se zdravotní péčí v ošetřovatelské praxi
KRAUSE, Martin
The aim of the dissertation thesis was to find out risky objects and surfaces used in the provision of nursing care in terms of transmission of healthcare associated infections. Another aim was to find out the current state of knowledge of nurses about the disinfection of objects and surfaces in the provision of nursing care. The last aim was to find out the microbial efficiency of nanomaterial applied to selected objects and surfaces in nursing practice. The research was carried out at a selected provider of health services, i.e. a regional hospital. The aims were achieved using a qualitative and a quantitative research methods. Part of the research was carried out with financial support within the student grant competition. In the first part of the research, risky objects and surfaces that are used in the provision of nursing care at standard departments of the selected hospital were identified by qualitative research using the technique of unstructured observation. In the second part of the research, the knowledge of nurses working in the departments of internal medicine and surgery in the principles of disinfection was found out by quantitative research using the questionnaire technique. Based on the results of the research, it was found out that the level of achieved knowledge depends on education, period of practice, age and department. However, knowledge is limited in some areas. In the third part of the research, the microbial efficiency of the nanomaterial applied to selected objects and surfaces (kidney dish, tray and box used to store medical material) was found out by quantitative research using an experiment. Based on the research results, it was found out that selected objects and surfaces with nanomaterial (antibacterial and hydrophobic nanolayer) showed bacterial contamination, i.e. it was not possible to demonstrate a statistically significant difference between bacterial contamination of objects and surfaces with and without nanomaterial. Further analysis revealed that, for example, kidney dishes would be contaminated with bacteria in 31.3% or trays in 38.1%. It was also found out that some objects and surfaces were also contaminated with pathogenic bacteria, such as Pseudomonas aeruginosa, Staphylococcus aureus, Enterobacter cloacae or Serratia rubidaea. The results show that adherence to decontamination of objects and surfaces, especially high touch objects and surfaces, it is important to pay attention at all times, to improve knowledge and skills of nurses involved in providing care to patients and seek new ways to implement preventive measures to minimize transmission of healthcare associated infections. The dissertation thesis thus provides an insight into the prevention of healthcare associated infections problematics in the context of the use of reusable high touch objects and surfaces requiring chemical disinfection in the provision of nursing care. It also provides evidence for compliance with binding hygienic-epidemiological measures and verification of new possibilities for reducing the risk of transmission of healthcare associated infections. The dissertation thesis is beneficial in the field of education, practice, but also for further research in this problematics.

Metodika dezinfekce fotografických a filmových materiálů s želatinovou světlocitlivou vrstvou
Knotek, Vítězslav ; Ďurovič, Michal ; Mašek Benetková, Barbora ; Hricková, Kateřina ; Limpouch, Ondřej ; Nováková, Martina ; Hnulíková, Blanka ; Borýsková, Štěpánka ; Sýkorová, Hana ; Purkrtová, Sabina ; Kadavá, Jana ; Savická, Dana ; Stiborová, Hana ; Branyšová, Tereza ; Demnerová, Kateřina
Uvedená metodika navrhuje postup identifikace historické fotografické techniky a kinofilmů na acetátové a polyesterové podložce, optimální odběrový materiál a techniku odběru vzorku pro mikrobiologickou analýzu, která vychází z doporučení již publikované „Metodiky odběru a izolace bakterií, kvasinek a plísní z fotografických materiálů“ pomocí suchého stěru pomocí měkké polyuretanové (PUR) houbičky. V případě pozitivního výsledku mikrobiologické analýzy jsou navrženy dezinfekční metody, které nepoškozují černobílé želatinové fotografie (páry n-butanolu) a filmové materiály s želatinovou světlocitlivou vrstvou na acetátové podložce (kvarterní amoniová sůl nebo etylenoxid v plynné směsi) a polyesterové podložce (etylenoxid v plynné směsi).

Uvedená metodika navrhuje postup identifikace a následné dezinfekce matných a lesklých kolódiových pozitivů na papírové podložce s barytovou mezivrstvou. Ve svém doporučení mikrobiologického odběru se opírá o již publikovanou „Metodiku odběru a izolace bakterií, kvasinek a plísní z fotografických materiálů“. V případě pozitivního mikrobiologického nálezu jsou v předkládaném textu doporučeny metody (ethylenoxid v plynné směsi, páry n-butanolu), které se ukázaly jako nedestruktivní vůči zkoumaným kolódiovým pozitivům.
