Sciranka, Peter ; Kislingerová, Eva (advisor) ; Kupec, Olga (referee)
The rapid evolution of a turbulent world economy in recent years has caused problems to a large number of enterprises, especially those that operate in cyclical sectors of the economy. The aim of this thesis is the financial and economic analysis of the company Abydos s. r. o., which operates in the engineering industry and its main business is supplying components for the automotive industry. Another objective is to analyze selected parts of the manufacturing process and design optimization and measures that would help the company improve the process and thus improve economic results of the company.
The hazards of harmful chemical substances in metal production environment, measuring and assessment.
GRUBEROVÁ, Michaela
The target of the thesis was to evaluate the risk of chemical harmful substances and dust in the working air of metal production. Four research questions were asked: {\clqq}What harmful substances are fixed in the working environment of the metal production?`` {\clqq}Are the hygienic limits of chemical substances and dust in the working environment of metal production observed?``, {\clqq}What measures were taken by the employer for the purpose of the health protection of employees?`` and {\clqq}Are the measures taken by the employer for the purpose of the health protection of employees effective?`` The thesis was treated as qualitative research. The followed file consisted of three South Bohemian companies dealing with metal production. The method of the direct, non participating and clear observation was applied for the data collection, moreover the study of documents {--} testing reports. The secondary analysis of data was performed. The results of measuring were compared with the hygienic limits fixed by the Directive of government No. 361/2007 Coll.. The evaluated professions were divided in categories pursuant the Directive No. 432/2003 Coll. In the working air of metal production, the concentration of the total dust, chromium, hexavalent chromium, carbon monoxide and ozone were followed. The last measuring in the monitored workshops proved that the hygienic limits were observed, except for two cases when the highest acceptable concentration determined for chromium and the chromium (II,III) compounds as Cr, and of the hygienic limit for welding fumes were exceeded. The most important protective measure applied by the employers on their workplaces was the reconstruction of air-conditioning, or installation of local exhausting. In view of the gradual decrease of the harmful substance in the working air in connection to the taken measures may be stated that the given measures were effective. The hypothesis {\clqq}Modernisation of operations in metal production improves the working environment of employees and in the modern operations no above-the-limit values of the most monitored harmful substances were found out. ``
Sanitary issues of dust nuisance in smelting works
NAVRÁTIL, Jakub
In the environment of smelting works we meet many risky factors endangering the health of employees. Due to the excessive exposure to these risks, employees may suffer from many health problems. Many aspects play an important role in the rise of these problems. They are, for example, fitness and individual performance, ability to adapt, age, sex and etc. Dust is one of the most important factors affecting the organism of each employee during the job at smelting works. My Bachelor´s Thesis, in its theoretical part, summarizes the basic information about the issues of dust by using available literature. It specifically focuses on the characteristics of this risk, essential knowledge regarding the anatomy of airways, describes effect of dust on an organism and shows related illnesses. The objective of the practical part was to create a hypothesis in the area of risk related to dust nuisance in the smelting works, analyze the health risk of this factor in working conditions and segmentation of jobs into categories. To achieve the objective of the research 3 hypothesis have been set. A method of quality research was selected {--} especially secondary analysis of data. Nine employees together in various work places of chosen smelting works were measured and based on the analyzed data from measuring and examination all 3 hypothesis have been confirmed. The results of the research have shown that concentration of dust with fibrogenous effects in the work place of the smelting works exceeds the limit, work at smelting works is risky, and implemented measures related to health safety at work eliminate the damage to the health of the employees as much as possible. This Bachelor´s thesis can be used to increase the awareness in health related risks at smelting works.
