Noise and its health hazards, noise studies and preventive measures
Barvířová, Šárka ; Hrnčíř, Evžen (advisor)
In my work I have focused on evaluating health risks in the work-environment. I describe a biological effect on the auditory apparatus and the adverse effects of noise on human health, the breakdown of noise according to its types and its sources. The results show that the noise does not cause specific disease to the exposed persons, but generally their health status is getting worse and contributes to the earlier breakout of disease that would otherwise be reflected later and worsens their procces. In the part of the prevention and protection the options are described in the work and off - work environment . The most important prevention of noise I would firstly state above all the legislative measures. The most effective precaution is to reduce noise at its source. Further it is in my work dealt with the possibilities of the noise measurement and division of work with exposure to noise in four categories, which are set by legislation. In conclusion, I described a case report in assessing health risks in the work of health professionals, including hygienic stations, including the public health surveillance of health conditions discharging noise limits established the law to protect public health. The case report is presented a procedure for resolving complaints about noise from a music club.

Diseases caused by ionizing radiation
Gronychová, Soňa ; Hrnčíř, Evžen (advisor)
The topic of my thesis Diseases caused by ionizing radiation have I chosen on the basis of his interest in this issue. The observation that exposure to ionizing radiation is associated with health risks , coinciding immediately after the discovery of X-rays and radioactivity in 1895 and the 1896th already in the following year was reported by erythema and eczematous changes in the skin. very Mr. discoverer of radioactivity Becquerel in 1901 convinced about the negative effects of their own discovery when he wore 14 days in his vest pocket radio preparation which gave him couple Curie . He appeared with him at length and eczema -healing ulcer , which also confirmed and self- forearm tried P.Curie . Already in 1902 , six years after the discovery of X-rays showed Frieben in Hamburg first tumor induced by radiation. Between 1927 and 1928 the geneticist HJ Muller reported the induction of mutations in X-rays and genetic consequences resulting from radiation exposure . Single and repeated radiation exposure of an appropriately high doses cause radiation syndrome with typical somatic symptoms and consequent death which probability increases with increasing dose . In the first decades of the use of ionizing radiation in diagnosis and therapy are so many rentgenologové and radiologists become demonstrably victim...

Effect of sound on health
Dorková, Lenka ; Hrnčíř, Evžen (advisor)
Sound , whether in a positive or negative effect on man every day of his life . Since coming to the world around us different sounds , pleasant voice from the mother to the noise from automobile traffic outside the window . The sound then accompanied us for the rest of our life , allows our communication is a means of pleasant sensations . Unfortunately, the majority of the population moving into large agglomerations , the development of technology and transport in our daily life we encounter at every step too noise and unpleasant consequences. In my thesis , I would like to address the deeper issues of sound and its effect to humans. In the first chapter, I outline the physical nature of sound, to address the basic physical concepts related to sound and acoustics and briefly bring even the structure of the human auditory system, which allows us to register the sound around us and analyze . In the second chapter, I will own sound effects to humans , the definition of noise, to think of its source and paid to the effects on the human body . I would also like to further analyzed Czech legislation dealing with noise and its health limits . In the second part I will discuss the positive effects of sound , especially on behalf of music and its therapeutic effects , ie music therapy. The aim of my work is to...

Occupational Diseases in the Czech Republic
Svobodová, Gabriela ; Hrnčíř, Evžen (advisor)
Occupational diseases include a heterogeneous disease, whichcombines strong socio-economic impact for the patient and society. Monitoring the incidence of occupational diseases is an important indicator Population Health. Our duty is to spread awareness of possible consequences of non-work safety rules and most effective prevention to prevent any injuries from work. In my thesis I intend to illuminate the issue of occupational diseases and their legislative definition and categorization according to the Section. The practical part will be devoted to monitoring trends in incidence of occupational diseases in the last ten years, andstatistical comparisons Data of disease between men and women.

Occupational Diseases in the Czech Republic
Baciak, David ; Hrnčíř, Evžen (advisor)
Occupational Diseases (NzP) are diseases whose definitions is defined by current legislation. The definition is based on Law No. 65/1965 Coll. Labour Code, as amended, Act No. 155/1995 Coll. pension Insurance, and Government Regulation No. 290/1995 Coll.establishing list of occupational diseases, divided into 6 chapters (see Annex No. 1). I Occupational diseases caused by chemicals II Occupational diseases caused by physical factors III Occupational diseases of the respiratory tract, lungs, pleura and peritoneum IV of occupational skin disease In Infectious and parasitic illnesses VI Occupational diseases caused by other factors and actors Each chapter represents a group of professional disease, which is either a common etiological factor (chemical, physical or biological, that is infectious noxa) or disability such a body, which is particularly exposed to influences work environment (skin, respiratory system, musculoskeletal system). Each chapter is then further divided into different number of items that represent nosologickou unit or group of related or diseases include diseases caused by the same etiological noxou professional.

Diseases Related to Diving and Their Prevention
Chytil, Matěj ; Hrnčíř, Evžen (advisor)
Disease which are connected with diving are mostly caused by changes of surrounding pressure. Liquids don't make any harm in organism,due to incompressibility under this conditions.Causal problems are caused by gas and spaces that are filled with it.Gas changes its capacity because of changes of the pressure and temperature and It exerts to walls of spaces filling with it.This fact is responsible for more than half causes of all diseases related with diving.The second half of diseas is caused by changing solubility of gas contained in liquids during changes of surrounding pressure.Other causes are mostly marginal

Diving diseases
Rejdovjan, Simon ; Hrnčíř, Evžen (advisor)
This thesis mentions the basic physiological and physical principles of diving, it deals with diseases and injuries that occur in the connection with diving. The diseases are divided according to the phase of the diving as follows: The diseases originating from the change of surrounding pressure, diseases connected with staying in the depth and diseases stemmed after emersing above the surface of the water. Deeply elaborated chapter about Decompression disease includes a scale of predispositioning factors to this disablement. Next it mentions diseases that are not connected with the change of surrounding pressure. This part of my thesis describes the different forms of poisoning by enhaled gases, infectious diseases, drowning, hypothermia, hypoxia and it also includes an extended chapter that deals with sea animals and their potentional danger for human organism. The work also references to some preventive processes which can minimalize the risks of occurence of these diseases and injuries.
