Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Subsidy Support of the Sustainable Waste Management
BEDNÁŘOVÁ, Renata
The subject of the dissertation is the issue of the waste management with special emphasis on the recycling of the construction and demolition waste. The recourse is an analysis of the key instruments regulating the activities and behaviour of market operators in this field toward fulfilling all-society priorities and principles of the sustainable development, where special accent is put on the area of subsidy policies and programmes. The aim of the dissertation is to analyse and evaluate the setting of the selected subsidy programme in terms of economic and ecological efficiency with the emphasis on the assessment of the impact on the recipient. The subject of the research will be a priority axis 4 "Improvement of Waste Management and Removal of Old Environmental Burdens" within the Operational Programme Environment 2007 - 2013. In the literature review basic concepts and important definitions are defined, followed by the comprehensive and complex searches of the problematics from different angles of view. First of all, the global aspect of environmental protection is discussed, broader historical, legal, economic and political contexts, that are essential fundament for understanding the current and future challenges both globally regionally, are summarized. Hereafter, a more detailed description of the situation of the European Union is followed, then the overview is completed by a detailed view at the state of the problematics in the Czech Republic. Subsequent chapters are devoted to a detailed analysis of the waste management sector, again in terms of global, European and national standpoint, in the end the view is focused on the key issue of the dissertation problematics of construction and demolition waste. In the application part the fulfilling of the stated objective of the dissertation through four defined hypothesis is solved. Hypotheses verify the efficiency and appropriateness of the setting of the system of subsidies in the frame of the monitored programme. The emphasis is imposed on the assessment of the impact of the allocated subsidies to the private entities on their economic and environmental efficiency.

Packet Classification Algorithms
Puš, Viktor ; Lhotka,, Ladislav (referee) ; Dvořák, Václav (advisor)
Tato práce se zabývá klasifikací paketů v počítačových sítích. Klasifikace paketů je klíčovou úlohou mnoha síťových zařízení, především paketových filtrů - firewallů. Práce se tedy týká oblasti počítačové bezpečnosti. Práce je zaměřena na vysokorychlostní sítě s přenosovou rychlostí 100 Gb/s a více. V těchto případech nelze použít pro klasifikaci obecné procesory, které svým výkonem zdaleka nevyhovují požadavkům na rychlost. Proto se využívají specializované technické prostředky, především obvody ASIC a FPGA. Neméně důležitý je také samotný algoritmus klasifikace. Existuje mnoho algoritmů klasifikace paketů předpokládajících hardwarovou implementaci, přesto však tyto přístupy nejsou připraveny pro velmi rychlé sítě. Dizertační práce se proto zabývá návrhem nových algoritmů klasifikace paketů se zaměřením na vysokorychlostní implementaci ve specializovaném hardware. Je navržen algoritmus, který dělí problém klasifikace na jednodušší podproblémy. Prvním krokem je operace vyhledání nejdelšího shodného prefixu, používaná také při směrování paketů v IP sítích. Tato práce předpokládá využití některého existujícího přístupu, neboť již byly prezentovány algoritmy s dostatečnou rychlostí. Následujícím krokem je mapování nalezených prefixů na číslo pravidla. V této části práce přináší vylepšení využitím na míru vytvořené hashovací funkce. Díky použití hashovací funkce lze mapování provést v konstantním čase a využít při tom pouze jednu paměť s úzkým datovým rozhraním. Rychlost tohoto algoritmu lze určit analyticky a nezávisí na počtu pravidel ani na charakteru síťového provozu. S využitím dostupných součástek lze dosáhnout propustnosti 266 milionů paketů za sekundu. Následující tři algoritmy uvedené v této práci snižují paměťové nároky prvního algoritmu, aniž by ovlivňovaly rychlost. Druhý algoritmus snižuje velikost paměti o 11 % až 96 % v závislosti na sadě pravidel. Nevýhodu nízké stability odstraňuje třetí algoritmus, který v porovnání s prvním zmenšuje paměťové nároky o 31 % až 84 %. Čtvrtý algoritmus kombinuje třetí algoritmus se starším přístupem a díky využití několika technik zmenšuje paměťové nároky o 73 % až 99 %.

Právní a zdravotně sociální aspekty činnosti OSPOD jako ustanovených opatrovníků v zámu nezletilých dětí
BORSKÁ, Jana
The Czech Republic as a signatory of the Convention on the Rights of the Child has vested the practice of state administration in the field of care for minor children to municipalities with extended powers, where the protection of the rights and legitimate interests of minor children is safeguarded by state authorities of social and legal protection of children (ASLPC hereinafter). These authorities are incorporated to the extent laid down by the Act on Social and Legal Protection of Children (Act No 359/1999 Coll., as amended). The position and roles of ASLPC and their competence and jurisdiction are also regulated by the same act. The position of workers of these authorities and its legal embodiment is equally important. Regarding professionality, there are high demands on these workers. In the Czech Republic, significant changes in legislature have been made over the past three years. These amendments have led to the strengthening of the rights of minor children and to the establishing of new tools for their protection. In connection with the adoption of new substantive regulation of family law, which is now exhaustively dealt with by the Act No 89/2012 Coll., the Civil Code, new procedural rules have been established regarding protection of rights of minor children. Such procedural legislation includes (apart from the long-existent Act No. 99/1963, the Code of Civil Procedure) the Act No 292/2013 Coll., on Special Civil Proceedings. The decision-making regarding minor children has been vested mainly by the state into the competence of courts. The courts appoint the locally relevant ASLPC as a guardian who then represents the interests of minor children. The purpose, interwoven with and derived from the first one, was to explore the opinions of selected social workers of ASLPC and of district court judges regarding the defined problems occurring during the work of ASLPCs and courts while protecting the interests of minor children. These particularly include: the use of the tool of precautionary measure; problems of different territorial jurisdiction of courts and ASLPCs; processing of complaints regarding bias in various phases of the proceedings; professional training of workers of ASLPC It is evident from the proposals of both judges and ASLPC workers that it is necessary to unify territorial jurisdiction. The courts are suggesting the priority criterion of the address where the child mainly resides. ASLPC workers suggest the official permanent residence as the prime criterion. Bias causes problems in all phases of proceedings. It is obvious that courts take differing approaches towards the solution of this problem (some courts solve the problem of bias complaints filed by the parties while other courts do not) and for ASLPC workers it is difficult to assess how to act when such complaint is raised against them. The training of ASLPC workers - workers are obliged to educate themselves and their employer is obliged to finance such training. Not all ASLPCs are able to provide training in the required extent - due to financial reasons (the average costs of education of one employee pose from 9,169 to 13,400 CZK annually and they cover approximately 6 days of training). The heavy work-load caused by insufficient numbers of ASLPC employees prevents them from completing such compulsory training. As part of the examination of the "participation of a collision guardian in court proceedings" it has been found out that irregular participation of the worker in the proceedings (absence from participation in appeals proceedings); incomplete reports (directed to courts) from surveys in families. Based on comprehensive examination of the problems of territorial jurisdiction, it was recommended that requests are independently recorded and financial compensation is provided for ASLPCs who are requested to represent minors in front of courts, to draft proposals for precautionary measures.

Are There Any Digital Curators in Czech Libraries?
Římanová, Radka ; Melichar, Marek
The development of digital repositories reveals the need for new Czech terminologies for library positions. One such job title or specialization is “digital curator”, a term which refers to a specialist responsible for digital collections. Competencies for digital curators include technical, organizational, communication, and marketing skills as well as some level of expertise in computer science as well as in information and library science. A survey of several administrators of Czech digital libraries asks how to best professionally label this group of library staff with respect to the actual activities they perform in their jobs - digital curators, administrators of digital libraries, or digital librarians? Job titles have a strong impact on higher education curricula, on the management of libraries, and also on the coordinated system of remuneration of employees at libraries, academic, and research institutions.

Specificity of insect-plant associations and their role in the formation of plant defenses and speciation
VOLF, Martin
The aim of this dissertation is to investigate what role insect-plant interactions play in the formation of host-plant defenses and in the diversification of both groups. We show that various groups of herbivore respond differently to host-plant defenses. Therefore plant defenses diversify into suites of complementary traits, as individual traits fail to provide protection against specialized herbivores. Further, we identify what levels of host-phylogeny shape the food-web structure of insect herbivores. We show that specialized herbivores are affected mainly by the terminal parts of the host-phylogeny. In contrast, more polyphagous guilds are affected mainly by the mid-levels of the host phylogeny because the effects of terminal or deeper phylogeny seem to be surpassed by other factors in more generalist insect species. In the last chapter, we show how specialized insect-plant interactions generated by tight insect-plant coevolution can influence the speciation in plants over environmental gradients.

Al forms in acidified surface waters - toxicity and trends
Šimková, Petra ; Hruška, Jakub (advisor) ; Hořická, Zuzana (referee)
This thesis deals with forms of aluminium occurring in acidified surface waters. Special attention is paid to inorganic monomeric aluminium, fraction, which has toxic effect on some species of aquatic and terrestrial biota. The thesis primarily focuses on the analysis of surface water, groundwater and soil water chemistry in the year-round and long-term monitoring. The practical took place on an experimental mountain basin Uhlířská, which is drained by river Černá Nisa. Uhlířská basin is located in the Jizera Mountains and represents the area which was significantly exposed to the acid atmospheric deposition in the second half of the 20th century. Long-term exposure to acid precipitation caused the acidification of soil and watercourses, forest degradation and deforestation of large parts of the basin. Decrease in pH and an increase in concentration of toxic aluminium also caused species depletion of aquatic ecosystems. Monomeric forms of aluminium were determined spectrophotometrically, the concentration of total aluminium was determined by the method of flame atomic absorption spectrometry (FAAS), in case of low concentration electrothermal atomic absorption spectrometry (ETAAS) was used. Five forms of aluminium were obtained - Altot, AlAS, Alm, Alo and potentially toxic Ali. Appart from...

Effect of a graduate of field of study Special Education - tutorship in practice of providers of social care
SALABOVÁ, Jana
Theoretical part of the thesis is divided into 4 main chapters. First one deals with the helping professions generally, their definitions and definition of the Special education - Tutorship branch of study per se.It also briefly touches the subject of readiness of the future graduates to deal effectivelly with the challenges of a career in the field of social services. Chapter number two is called Special education and it defines the subject of special education itself, it's purpose and inner structure. Third chapter focuses on social services. It brings up it's definition and types and forms of social services.It also contains the examples of the institutions which fall into this category and it's providers. Chapter number four, which happens to be the last one in the theoretical part of the thesis, covers the role and purpose of graduates of the special education - tutorship studies. It brings up the definition of a social worker, necessary prerequisites as well as beneficial personality traits and feautures. In a subchapter of chapter four is a short description of a pedagogue tutor. Definition who he actually is, who are proper candidates for this position, what are desired personality traits we look for in tutors and the actual content and purpose of their work in institutions providing social services. The end of chapter four is dedicated to a position of a social worker. His activities, the position and definition of a personal assistant and again personality traits needed for a successful career in this field. The objective of the practical part of the thesis is to describe working of Special education - tutorship studies graduates in practice. Particularly their experiences "from the field", how do they evaluate the level of skill of fresh graduates during their first encounters with the reality, how satisfied are they with their choice of a career so far and what was their motivation to pursue such career. Practical part of the thesis includes qualitative research. To meet the above objectives, data collection technique had been chosen using a structured interview with the respondents, who were graduates of Special education tutorship studies. You can tell by the results of this thesis that graduates in the field of social services apply mostly to lower positions as a social service workers, even though they are qualified to perform as a social workers. The age of clients with whom the respondents work ranges from childhood to senior. The motivation that led those questioned respondents to the decision to choose the area of social services varies. Some reported that they were influenced by the actual practical experience during their studies at the university, when both the work itself and their enthusiasm for the target group played role. Others expressed they had previous experience working with people with disabilities or they just wanted to acquire new experiences. Also, involvement of a family member and their previous education was a motivation. Job satisfaction is evident from observed data, and it also contributes to work done accurately and responsibly. Personal benefits for the respondents according to findings are usually their usefulness at work, new experiences they are getting and last but not least advances of their clients. As the biggest advantage the respondents usually mention variability of their work, target group and the clients in itself and the fact, that their work is highly satisfying and they basically work in a very pleasant team of individuals. On the other hand, not exactly satisfying financial reward and challenging working hours are mentioned as disadvantages. Special education - tutorship studies - the branch they've studied, is by the majority of respondents considered to be beneficial for them and they especially highlight practical impact of practice they completed during their studies and which included visits to various relevant institutions.
