Analysis of selected factors affecting occurrence of Chalara fraxinea in the environment.
Havrdová, Ludmila ; Šrůtka, Petr (advisor) ; Jaroslava, Jaroslava (referee)
Extensive investigation of ash dieback impact on different rural vegetation types (solitaires, scattered plantations, riparian stands, scree- and ash-alder alluvial forests) was performed in the Lusatian Mts. (the Czech Republic) between 2011 and 2013. The rate of ash dieback and 27 environmental variables were investigated in 80 research plots with a total of 1045 evaluated trees. The developed model (GLM) explained ca 27% of the disease variability. Particular models for each vegetation type importantly differed from each other and explained 28--46% of the disease variability. The variables that positively affected the disease impact included the host crown area, ash area and rate of ash in the stands, tree layer area, canopy closure, north aspect, shrub and herbaceous layer canopy, vertical heterogeneity and standard deviation of TPI. Tree height, the distance and damage of the nearest host as well as the water source distance, slope and its standard deviation affected it negatively. The coincidental attack of the trees by Armillaria sp. and Hylesinus fraxini positively affected the disease progress, whereas the presence of Nectria sp. and Aceria fraxinivorus conclusively decreased progress, most likely via the induction of secondary metabolites. The highly conclusive regression of ash dieback on the number of days with an air humidity of >95% between 6--11 a.m. in the main period of ascospore spread was identified. Because the air humidity near the ground was highly affected by local factors, a GLM model explaining the variability of air humidity with that of investigated factors was developed. This model explained 77% of the variability attributed to air humidity, local factors (TPI and SD of TPI, aspect, slope, altitude, distance from open water, tree and shrub layers canopy, tree stand height, etc.) greatly affected the disease impact related to air humidity. The landscape form was identified as a factor (most likely via air humidity) that affects the impact of the disease -- for example, the stands on mountain tops and slopes were less affected than the stands in valleys. The vegetation types highly differed in the disease extent. In general, the solitaires and scree forests were significantly less damaged than mixed ash-alder forests and riparian stands. The smaller stands were less affected than the more extended, the stands enclosed in canopy of other forests were less damaged than comparable vegetation in open landscapes and stands with higher humidity (riparian stands and mixed ash-alder forests) were more damaged than those without water. The outcome clearly supports the possibility of development and usefulness of appropriate forest and landscape management of the disease.

Practical application of ICF
SVĚCENÁ, Kateřina
The International Classification of Functioning, Disability and Health (ICF) is a tool that could help improve the coordination between health and social services. This classification will help with communication as a common language in interprofessional rehabilitation team. The research objective of our thesis is to investigate the practical applicability of ICF in health and social services in the field of regulations governing entitlement to "special aids", i.e. Act No. 329/2011 and Decree No. 388/2011, as amended.

Improvement of the Family Life in the Czech Republic (Analysis of the situation Písecku)
PEKÁRKOVÁ, Martina
Thesis deals with Improvement of the Family Life in the Czech Republic, mainly analyzes the situation in Pisek area. It is divided into two parts, theoretical and practical. The theoretical part describes the various chapters by literature relevant terms, such as family (functional, at risk), parenthood, family rehabilitation. Subsequently, explains the factors affecting the rehabilitation and aspects, working methods, cooperation with the family, an individual rehabilitation plan, cooperation with experts in the multidisciplinary team. Further described the current legislation and the transformation of care for vulnerable children in the CR. The practical part is devoted to mapping and description of organizations providing rehabilitation to families in Pisek area. The practical part was conducted qualitative research, which dealt with the form of work with clients, cooperation with other agencies and assess is needed for remediation. Respondents were employees of the research organization providing remediation. The practical part of the bachelor combines theoretical work.

The occurrence of brook lamprey (\kur{Lampetra planeri })in the Malše River near Kplice
BRABCOVÁ, Miroslava
Within the frame of the ichthyological survey of the Malše River in Dolní Dvořiště and several river profiles upstream the Kaplice town the presence of brook lamprey (Lampetra planeri) was proved. In years 2007-2009 in six localities of the Malše River between Dolní Dvořiště and Kaplice town the occurrence of the species was proved. Lamprey larvae created more than 90%, catch of adult lampreys was low. In time period investigated the densities were relatively low (8 inds./m2 maximally) and were not significantly different between compared years and localities sampled. Lampreys densities were influenced by current speed and rate of shade. Physical {--} chemical parameters of water (temperature, pH, oxygen concentration, conductivity) and also water depth and thickness of sediment were in the range of optimal values in the sampled microhabitats so any correlations between these parameters and densities of lampreys were not observed.
