IT Security in Biomedicine.
Schlenker, Anna ; Šárek, Milan (advisor) ; Nakládalová, Marie (referee) ; Brechlerová, Dagmar (referee)
Title: IT Security in Biomedicine Author: Ing. Anna Schlenker Supervisor: Ing. Milan Šárek, CSc. Abstract: The aim of this work is to propose a solution to the biomedical data security strategy. The work provides an overview of the most commonly used biometric methods designed to identify or authenticate users. From these methods, the keystroke dynamics was chosen and used in the application solution. The reliability of this method has been tested by classical and modern classification methods. The greatest benefit of the work is the use of the created application in combination with the measurement using integrated electromyography to objectify the evaluation of the work related to keyboard typing in terms of local muscle load. Keywords: Biometrics, Data Security, Keystroke Dynamics, Local Muscle Load

Risk assessment, prevention and health support at a workplace of a selected plant in the Olomouc administrative region
SVOBODOVÁ, Klára
The objective of this work was to assess the health risk of local muscular stress of the upper limbs associated with the operator's job at a workplace of a selected plant in the Olomouc administrative region and to propose adequate provisions. Three research questions were asked: (i) "Are the permitted levels, set as percent fractions of the maximum load, complied with in the operator's job?" (ii) "Are the hygiene limits regarding the numbers of movements complied with in the operator's job?" (iii) "Which preventive actions are suitable to counteract the risk of local muscular stress during machinery assembling work?" This research was conceived as qualitative investigation. The group examined comprised employees at the position of operator at a workplace of a selected plant in the Olomouc administrative region. The research work comprised data collection by using the method of direct, non-participating and overt observation, and study of professional literature, applicable legislation and test protocols and reports. I processed the results of measurement and compared them with the hygienic limits laid down by Government Decree No. 361/2007 Coll. (as amended). Based on the assessment of the data obtained, I classed the operator's job as Category 3 with respect to the local muscular stress factor examined, based on the criteria set by Regulation No. 432/2003 Coll. (as amended). Based on the risk assessment and categorization of labour I proposed appropriate preventive measures to mitigate the effect of local muscular stress during the operators' work. I set up a simple questionnaire asking for a subjective assessment of the locomotive system stress during work as a tool for a more comprehensive assessment of the operators' local muscular stress. Based on the research I formulated the following hypothesis: "In view of the increasing trend of incidence of occupational diseases of the limbs due to overload, and taking into account the appreciable social and economic impacts of such diseases, more attention should be devoted to a systematic search, assessment and evaluation of the local muscular stress factor risk during work."

Evaluation of local muscular load off upper limbs in dental laboratory technician
PECHOVÁ, Eva
In the working environment we face lots of danger factors. A danger factor of local muscular load is still a big problem. At the work of dental laboratory technicians an enormous one-sided loading of upper extremities occurs, consequently vocational diseases may occur as well. It depends on the individual perception of load at each of us and on our working capacity. The absence of well-being resulting from the influence of danger factors on our organism leads to a number of various health problems, inadequate workload, fatique, and unpleasant feelings. Non- respecting the ergonomic requirements may also have negative impact on the health of workers. It may prove e.g. by an increasing number of work injuries, by problems with disorders of muscular and skeletal system, by overloading of muscular groups as a logical consequence of one-sided, long-term and excessive muscular load. In its theoretical part my bachelor´s work supported by literature available summarizes basic information on the problems of local muscular load. It focuses first of all on the characteristics of individual danger factors, on the basic pieces of knowledge of anatomy of upper limb, it describes physical load, some vocational diseases and also basic ergonomic requirements. The practical part is aimed at setting up a hypothesis concerning health danger resulting from local muscular load of upper extremities at dental laboratory technicians, evaluation of health danger of this factor of working conditions for classifying the work. For meeting the target of research three hypotheses were determined. The method of qualitative research was chosen {--} especially the secondary analysis od data. The research was carried out in the district of České Budějovice and four workers of a dental laboratory took part in it. On the basis of assessed data all three hypotheses were confirmed. The results proved that the work of dental laboratory technicians is danger work, local muscular load of upper extremities reaches a higher degree and values which enable to place it in the third category. The bachelor´s work may contribute to better knowledgeability of health danger. The suggested measures may help improve working conditions at a particular workplace
