On the limits and possibilities of the stature estimating from hand and foot measurements (hand stencils and foot impressions).
Havránková, Jiřina ; Brůžek, Jaroslav (advisor) ; Dobisíková, Miluše (referee)
This bachelor essay explains view of methods for stature estimation based on hand and foot dimensions. It appears from this view that regression functions are population specific. I have assessed this fact on the collection of 100 French students and I have applicated specific chosen regression equations on the exact group. For stature estimation the most suitable regression equation was the one created by Agnihotri and col. (2008). It provides the best results in an interval 11 up to 12 cms regarding the actual height. For one of the equations, which is using the length of the left hand and the breadth of the right hand of men, the results of the estimation is even 6 cms regarding the actual height. At the end, I tried to calculate my own equations, which offers the estimation results between 6 - 7 cms for the formulas working with the hand length, the estimation results is between 12 - 13 cms for the formulas using the breadth of the arm.

Ancient-DNA analysis of teeth and skeletal remains with utilization of miniSTR loci.
Kvítková, Dana ; Brouček, Jaroslav (advisor) ; Dobisíková, Miluše (referee)
During the last twenty years, immense progress occurred in the area of analysis of DNA extracted from historical material. Considering the common level of preservation of tissue material, this analysis is usually executed on samples procured from bones and teeth. The analysis of soft mummified tissue is possible only in rare cases. Limiting factor of these analyses is a high degree of degradation and small amount of DNA extractable from this kind of material. First researches concentrated only on short sections of mainly mitochondrial DNA. Today, the analysis of the complete mitochondrial genome of both contemporary and extinct organisms was made possible. In case of analyses conducted on human remains, sections of nuclear DNA are far more valuable, because they can reveal information including not only subject's sex, but also possible kinship between subjects found e.g. in the same grave. Fundamental component of the whole analysis is the process of extracting DNA from cells. Probably every laboratory working with historical DNA uses a differently modified extract protocol. The main requirement for methods of extraction is to secure enough DNA with such a level of purity that would allow its use for following steps of the analysis. Taking in consideration high fragmentation of DNA, it is necessary...

Digital forensic anthropology and sexual dimorphism of recent population os coxae: implication for sex estimation.
Mesteková, Šárka ; Brůžek, Jaroslav (advisor) ; Dobisíková, Miluše (referee)
This thesis uses the metric evaluation of 3D models created from CT images. The study is based on an examination of 51 males and 55 females CT scans from recent European population and also based on a metric data (10 linear measurements) of the same geographical provenance of the mid-20th century (n=113). The purpose of our research project is to determine the degree of sexual dimorphism in current population and compare the degree of sexual dimorphism in this geographic area in the middle of the last century. Intraobserver variabilities of linear measurements were less than 2%. Both groups were statistically tested. An index of sexual dimorphism (ISD) was used to assess the level of sexual dimorphism within each sample (Paris ISD = 8,28, Marseille ISD = 6,50). The two-sided t-test indicates that the degree of sexual dimorphism is not significantly different between population from the mid-20th century and recent population (p = 0,680). The secular trend was expressed by the z-score. The results showed that changes in the pelvic bone between the two groups are not significant, since neither one of the measurements does not exceed ±2 SD. Finally, we verified the reliability of method DSP ("Diagnose Sexuelle Probabiliste") for measurements deducted from CT-derived models. The results showed the...
