Acoustics of small fans
Hájková, Lenka ; Rubina, Aleš (referee) ; Cifrinec, Ivan (referee) ; Hirš, Jiří (advisor)
Dissertation thesis falls within area of indoor climate and deals with investigation of acoustic microclimate in sanitary rooms of residential buildings during a mechanical ventilation. Sources of a noise in these areas are small fans. The thesis contains the evaluation of the existing situation concerning the referred issue, physical laws of acoustics and theoretical basics of acoustics of air conditioning. The part of the thesis is experimental measurement which aims to evaluate the situation in real applications and the possibility of influencing the acoustic microclimate by affixing of small fans on the building structure. The work contains a model for the verification of certain anticipated dependencies and theoretical investigation of the distribution of sound pressure levels in the sanitary room, depending on the location of the noise source. The last part of the work offers possible measures to improve the acoustic microclimate and elimination of the noise in sanitary rooms and in protected areas of residential buildings.

Hájková, Lenka ; Pavlíková, Pavla (advisor) ; Brixiová, Simona (referee)
v AJ Topics of my study, its evaluation and final report for my bachelor's degree cover special topics and problems of blood transfusion administration. The literaty outfit of this study is dividend into a theoretical and a practical part. Theoretical chapters deal directly with basic problems of the subject and with principles of administration of blood transfusions in hospitalized patients. Description of anatomy and physiology of blood and its components, medical terminology of blood transfusions, their history, composition of blood products, guidelines for transfusion administration, adverse effects and complications form the introduction of the entire issue. Following practical part and chapters cover the background, aim and hypotheses considering the research - its methods and results. Data from MCQ - multiple choice questionnaires are presented in tables and graphs and discussed. Several interviews and experts' opinions and commentaries are added. Main data on administration of transfusions cover knowledge, practical realization of guidelines and standards in transfusion medicine in healt care providers, especially nurses, their clinical sense for patients' status and signs, cooperation with physicians, their immediate steps when confronted with transfusion adverse events and complications,...

Hájková, Lenka ; Řeháček, Vít (advisor) ; Jílek, Petr (referee)
Author: Lenka Hájková Title: Testing of HLA antigens and antibodies in the laboratory of transfusion department Bachelor's Thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Field of study: Medical Laboratory Technician Background: Retrospective study, overview of investigations of potential kidney recipients from 12 participating hemodialysis centres during 3 years (2008 - 2010). Methods: Following examinations were performed on potential kidney recipients in the HLA laboratory of the Transfusion Department, University Hospital Hradec Králové: serological fenotyping HLA-A, B (CDC test), PCR HLA-DRB1* genotyping (SSO, SSP) and screening of antileukocyte antibodies (CDC test). Results: The total number of 154 potential kidney recipients were examined during the period of time from 1. 1. 2008 to 31. 12. 2010 (2008: 57, 2009: 46, 2010: 51). Screening of antileukocyte antibodies was performed on 1 140 samples, the most frequent result of antibody levels was between 0 - 30 %. Most patiens were at age of 41 - 61 years, male/female ratio was 2:1. The most frequent HLA antigens concerning the group of patients with kidney diseases were HLA-A2, HLA-B8 and HLA-DRB1*11. Conclusions: During the period under consideration the number of newly registered potential kidney recipients did not...

Bioclimate of Liberec
Rubáš, Dominik ; Sládek, Ivan (advisor) ; Hájková, Lenka (referee)
The diploma thesis provides special studies from the human bioclimatology sector. Ten year sequences (2001-2010) of many meteorological components are processed here. The meteorological components are as follows: average daily air temperature, average daily wind speed, time of sunshine per day, duration of rainfalls, fogs and fumes and also monthly aggregate rainfall. The main study aims attention to evaluation of complex effects of selected elements on humans. The most and the least suitable season of the year for performing outdoor activities for a human were found, including optimal definition of summer holidays. Further studies concern the problems of air pollution related with synoptic situation. Sufficient space has been also given to more studies relating to wind chill or relations among individual meteorological elements, which can be helpful while forecasting the weather. With the help of particular data provided by Liberec hospital, the correlation between amounts of patients with particular diseases and changes of selected meteorological elements has been discovered.

Long-term and difficult weaning - discontinuation of ventilator- dependent adult patient
Hájková, Lenka ; Drábková, Jarmila (advisor) ; Srpová, Daniela (referee)
The main reason for choosing the topic of study, is an increasing number of long-term ventilator-dependent patients undergoing weaning proces from artificial pulmonary ventilation at intensive care units. The content of the chapters include anatomy and physiology of the respiratory system, pathophysiology and some diseases associated with the ventilator-dependence. Also, the development and charakteristics of the OCHRIP - NIP and DIOP, the weaning procedure and the role of the nurses in the weaning proces. This study presents goals and hypothesis of investigation, as well as a variety of methodologies used. The study presents two aims of the research. Firstly, to map the experience and knowledge of nurses when disconnecting patients from artificial lung ventilation. Secondly, to find out how nurses perceive the care of these patients, including their view on the possibilities for further development of weaning process care. The research was carried out at ARO, ICU, NIP and DIOP bed units at five hospitals and two faculties of Intensive Care. It involved an anonymous questionnaire of 147 respondents (nurses) and students. The main finding of the research is that nurses have sufficient knowledge and experience in weaning from mechanical ventilation, notwithstanding they underestimate their own...

TITLE: Use of Drama in Education in lessons of Literary Education in 2nd class of the Primary School AUTHOR: Lenka Hájková DEPARTMENT: Primary Education Department SUPERVISOR: Mgr. et Mgr. Irena Hanyš Holemá, Ph.D. ABSTRACT: This diploma thesis deals with the use of drama education in classes of literary education in the 2nd grade of elementary school. It compares two second classes at elementary school to understanding the main idea in fairy tales through dramatic education and the method of reading with questions. The theoretical part is focused on drama education, its methods, techniques, preparátory games and exercises, Framework Educational Program and literary education. The basis of the practical part was the realization of 5 lessons in dramatic education and 5 lessons of literary education in two second classes on 5 fairy tales with lessons. After 14 days, a test was conducted to determine whether dramatic education contributed in literary classes to improving and understanding the substance.
