Preparation of high-valueable gypsum binder
Hájková, Iveta ; Gazdič,, Dominik (referee) ; Fridrichová, Marcela (advisor)
This work is oriented on the preparation of high-voluable sulphate binder based on gypsum waste. One of the potential mineral resources in Moravia is Pregips chemical gypsum, produced by Precheza. This is the raw material, which is characterized by high purity, high quality and is economically acceptable. Beta burned gypsum plaster from this, however, need to modify due to suppression of the high needs of water mixing, which is determined by its morphology. The need for mixing water has a large impact on the strength of gypsum binders. Therefore it is necessary to find a suitable additive, which would reduce the coefficient of water in the preparation of porridge normal consistency.

Waste material based high-performance sulphate binders
Hájková, Iveta ; Kolář,, Karel (referee) ; Rovnaníková, Pavla (referee) ; Gazdič, Dominik (advisor)
The topic of this dissertation was the preparation of a high-quality sulphate binder based on secondary raw materials. For this purpose, the work was primarily focused on the laboratory preparation of beta gypsum from the selected industrial gypsum, the design of the technological process of production and its verification by pilot tests. In the next step, the thesis dealt with the modification of beta gypsum by a selected set of liquefiers. In addition to commercial dehumidifiers, the possible beta casting of beta gypsum was tested by increasing the zeta potential of the gypsum suspension. At the end, a complete complex of construction products was developed based on laboratory and semi-prepared beta plasters, consisting of gypsum plasters, mastics, gypsum premix and small plaster casts.

Teaching methods for hand hygiene
Hájková, Iveta ; Kordulová, Pavla (advisor) ; Kulířová, Veronika (referee)
Introduction to the issue and the importance of the topic: The subject of this diploma thesis is to focus on issues related to teaching methods for the practice of hand hygiene in health care professionals in medical facilities. The issue of increasing efficiency in education is today an increasingly relevant topic supporting the activity of every person. In medical facilities, we encounter a problem with employee motivation, mutual interaction and communication when practicing new nursing procedures (hand hygiene), (Cullen, 2017). Unfortunately, most lecturers still teach only traditional teaching methods and use activating methods minimally or not at all (Sitná et al., 2009). Such a stereotype in the teaching process often provides only mechanical reproduction of the learned content. There is no consideration of understanding and practical interconnection, which is often boring and cumbersome for employees (Duran et al., 2017). The lecturer should pass on theoretical knowledge and practical skills to the given employees and thus develop their attitudes necessary for the performance of their profession (Vengl, 2011). Although much attention is paid to education in the literature, the methods used are often briefly characterized and listed by the authors. The primary focus of this work is on...

Hand hygiene of healthcare workers providing care in a medical facility
Hájková, Iveta ; Kordulová, Pavla (advisor) ; Kulířová, Veronika (referee)
The subject of the bachelor thesis is focused on issues related to hand hygiene in health care workers, in the provision of care in the health facility. Even though this topic is often mentioned, it is in practice less understood or misinterpreted. Sometimes, it is neglected or downplayed by health workers. The theoretical part is divided into 7 chapters. Here is anatomy and physiology of the skin, microbiological and epidemiological situation, measures aimed at eliminating the source and avoiding the route of transmission, effective methods of disinfection, sterilization, elimination of microorganisms and their transmission, in the health facility. Hand hygiene and its techniques, proper use of personal protective equipment, nail hygiene and, last but not least, skin care. Explaining the concept of hospital infection, which increases morbidity and mortality of patients, increases both diagnostic and therapeutic interventions and generally aggravates the quality of care provided with prolonging the period of hospitalization. I have worked on a search for relevant resources on the subject. The sources I drew mainly from WHO guidelines, CDC, Decree No. 306/2012 Coll. and on the basis of a literature search from the National Medical Library. I received the consent to perform the action research from...
