Vliv rozdílných typů zástinu na vybrané vlastnosti plantáží Coffea arabica v okolí města Villa Rica, Peru
Ehrenbergerová, Lenka
Coffee belongs to very important crops in the world and it is traditionally grown in agroforestry systems. During the five years the four coffee plantations with different type of shading were studied in the foothills of the Peruvian Andes. The highest amount of carbon was found in the plantation shaded dominantly by Eucalyptus spp., followed by Pinus spp., Inga spp. and non-shaded site. The microclimatic characteristic measurement shows that shading reduces the mean air and soil temperatures and increases the air humidity, compared to the non-shaded site. It was recorded drier soil conditions at the shaded site. At all plantations, coffee variety and age had a significant effect on Coffee Leaf Rust incidence. The value of the timber stored in shade trees varied significantly. There were different results for different shade trees species (from 2% to 72% of the annual income from coffee production).

Robotizované dojení a jeho působení na dojnice
Ševčík, Jiří
The objective of the dissertation thesis was to evaluate the effects of two different types of milking systems (CMS - conventional milking system vs. AMS - an automatic milking system) on average daily milk yield, on frequency of attending robots, on pre-milking teat preparation procedures and stimulation and milking time, on the teats traumatization of Holstein cows. The experiments were performed in two locations: Žabčice School Farm of Mendel University in Brno and ZEMAX, a. s. in Šitbořice. Data was collected for a period 1st January 2014 to 15th December 2015. Higher average milk yield per day and lower milk yield per milking on the other hand on the farm with AMS were caused by a higher frequency of milking. Cows on farm with CMS were milked twice a day. On the farm with AMS dairy cows were milked in accordance with their own needs. Milking frequency in the AMS was in 2014 2.47, in 2015 2.88 per day. Heat stress has negative impacts on milk production. Effect of heat stress showed more markedly in 2015, which is probably related to the fact that the value of THI greater than 80 lasted longer. The length of pre-milking teat preparation procedures and stimulation various neighborhoods was found in AMS in 2014 from 0:13 min. to 0:16 min., in 2015 from 0:14 min. to 0:19 min. On farm with CMS time not be registered. The length of milking time with CMS in both years was 5:02 min. In AMS was in 2014 from 3:03 minutes to 3:53 min., in 2015 from 3:05 min. to 4:45 minutes. In process of milking machine teat traumatization were smaller when using AMS.

Characterization of indoor air in health care buildings
Hladíková, Dita ; Braniš, Martin (advisor) ; Holcátová, Ivana (referee)
Hospitals and healthcare facilities are very specific times of microenvironments, which requiring monitoring air quality. People who use healthcare facilities are due to a weakened immune system very sensitive to air quality. Acceptable indoor air quality in healthcare facilities may have adverse effects on job performance at the personnel and their errors may have very serious consequences. The aim of this paper is to evaluate the main components of the inner microclimate (temperature and relative air humidity) and concentrations of carbon dioxide in the environment of selected healthcare facilities in the Czech Republic and to compare the results with the related legislation. The measurements were carried out in two hospitals and nine private medical offices from December 2011 to March 2013. The results showed that the values of microclimate factors and the concentration of carbon dioxide in the environment of patient rooms were different in cold and warm part of the year. In the patient rooms the levels of relative humidity diverged from the legal requirements mostly in winter - while those of temperature in summer. The concentration of carbon dioxide was affected by the occupancy rate and the size of the rooms. Air quality in the operating theater was primarily characterized by very low relative...

The Health Risk Assesment of Employees in ARPIDA Center.
KOLÁŘOVÁ, Michaela
The target of my work was Health risks evalution of employees in ARPIDA center. This facility provides care for the persons with physical and multiple disabilities. Employees were evaluated for the following professional groups: physical therapist, special educator, teaching assistant, personal assistant and rehabilitation pool lifeguard. For my research I have set the following research questions: ?What are the conditions for the categorization of works in connection with the operation of ARPIDA center??, ?Is the work of workers with direct contact with handicapped persons with endurable physical stress??, ?Are the factors at work of all employees ARPIDA center same and is the same as classifying these factors into categories?? The thesis was based on the application of a qualitative survey. The data collection method was used to interview with employees and then it was taged by secondary data analysis methodology compiling study of expert sources. Based on this research it was found that the factors do not work at all studied the same profession, the same is not their classification into categories. Some professions are burdened by excessive physical exertion. Lifeguard pool doesn´t expose to physical exertion, but his work activities affect climatic conditions and exposure to chemicals. Factors in a higher category than the first, can negatively affect the health of workers, especially physical load factor. For more specific evidence that physical stress factor could be in the category of the third, risk, I recommend to accredited or authorized measuring of physical activity in the profession a physiotherapist. This bachelor thesis can serve as a resource to increase awareness of employees who are professionally engaged in work with handicapped persons and may be the basis for further research in this field.

Microclimatic conditions in train, public city transport and long distance transport driver´s cabins
VÍT, Zbyněk
In my paper I´ve intended to collect theoretical knowledge of the issue of microclimatic conditions in the workplace and it´s impact on health and performance of the worker with the scope to workplaces ? cabins of train, city public transport and long distance transport drivers. I have proceeded from legally binding regulations. In the theoretical part I have described particular requirements and limits of factors affecting the quality of the inner workplace environment. After the theoretical part I have dealt with the practical part where I have proceeded from measurements which I have attended personally. I have completed my own measurements with the results of other measurement records elaborated by State Health Institute in Prague. Perspective measurements were interesting due to the ways technical devices were working and set to provide optimum microclimatic conditions in workplace. The largest measurement results were those from electric train units, known in our railway transport system as ?Pendolino?. While in the workplaces of engine drivers the set year-long inner environment limits have been mainly implemented, in the driver workplaces of public city and long distance transport, summer outside conditions had an impact on significant worsening of the microclimatic conditions ? a big temperature load on drivers, which is impossible to be eliminated without financially demanding measures.
