Preparation of mutated forms of fosfatidylinositol kinase IIα
Gregor, Jiří ; Šulc, Miroslav (advisor) ; Košek, Dalibor (referee)
Phosphatidylinositol 4-kinases (PI4K) are enzymes that form phosphatidylinositol-4- phosphate, which is an important regulatory molecule and precursor for the synthesis of other regulatory molecules. PI4K are interesting from medical aspect, because of connection between their function and viral, malignant, metabolic and neurodegenerative diseases. PI4K type II are inhibited by calcium cations, whereas PI4K type III aren't. The goal of this thesis was to elucidate the relationship between structure and regulation of function of PI4K IIα, specifically regulation by calcium cations. We failed in preparation of mutated forms of PI4K IIα that wouldn't be inhibited by calcium cations. However, the results obtained suggest, how aminoacids N313, D346 and E193 affect the kinase activity of PI4K IIα. (In Czech)

Effective proposal and operation of sorting line as an element in waste management
Guštara, Dominik ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The hereby presented master’s thesis deals with municipal solid waste separation. The introductory chapters describe current state of handling of selected recyclables and the technologies of their collection. The following chapter is a description of a waste sorting line technology, since this facility’s function is to upgrade the recyclables to secondary materials. The first step of practical part of this thesis was creation of a technical-economic model of the sorting line designed to process plastic and paper waste, therefore the following chapter is dedicated to its description and presentation. Subsequently, the outputs of the model are evaluated for three settings of its input variables, which represent the three imagined scenarios of the modeled sorting line’s operation. Sensitivity analyses focused on selected input variables of this model were also performed. A separate chapter is dedicated to changes in the model outputs in the case of including the waste transportation prices to the selected scenario. At the end of the thesis, the influence of increased material separation of plastic waste on the lower heating value of residual mixed municipal solid waste is evaluated.

Business rule learning using data mining of GUHA association rules
Vojíř, Stanislav ; Strossa, Petr (advisor) ; Pour, Jan (referee) ; Kouba, Zdeněk (referee) ; Gregor, Jiří (referee)
In the currently highly competitive environment, the information systems of the businesses should not only effectively support the existing business processes, but also have to be dynamically adaptable to the changes in the environment. There are increasing efforts at separation of the application and the business logic in the information system. One of the appropriate instruments for this separation is the business rule approach. Business rules are simple, understandable rules. They can be used for the knowledge externalization and sharing also as for the active control and decisions within the business processes. Although the business rule approach is used for almost 20 years, the various specifications and practical applications of business rules are still a goal of the active research. The disadvantage of the business rule approach is great demands on obtaining of the rules. There has to be a domain expert, who is able to manually write them. One of the problems addressed by the current research is the possibility of (semi)automatic acquisition of business rules from the different resources - unstructured documents, historical data etc. This dissertation thesis addresses the problem of acquisition (learning) of business rules from the historical data of the company. The main objective of this thesis is to design and validate a method for (semi)automatic learning of business rules using the data mining of association rules. Association rule are a known data mining method for discovering of interesting relations hidden in the data. Association rules are comprehensible and explainable. The comprehensibility of association rules is suitable for the use of them for learning of business rules. For this purpose the user can use not only simple rules discovered using the algorithm Apriori or FP-Growth, but also more complex association rules discovered using the GUHA method. Within this thesis is used the procedure 4ft-Miner implemented in the data mining system LISp Miner. The first part of this thesis contains the description of the relevant topics from the research of business rules and association rules. Business rules is not a name of one specification of standard but rather a label of the approach to modelling of business logic. As part of the work there is defined a process of selection of the most appropriate specification of business rules for the selected practical use. Consequently, the author proposed three models of involving of data mining of association rules into business rule sets. These models contain also the definition of a model for the transformation of GUHA association rules in the business rules for the system JBoss Drools. For the possibility of learning of business rules using the data mining results from more than one data set, the author proposed a knowledge base. The knowledge base is suitable for the interconnection of business rules and data mining of association rules. From the perspective of business rules the knowledge base is a term dictionary. From the perspective of data mining the knowledge base contains some background knowledge for data preprocessing and preparation of classification models. The proposed models have been validated using practical implementations in the systems EasyMiner (in conjunction with JBoss Drools) and Erian. The thesis contains also a description of two model use cases based on real data from the field of marketing and the field of health insurance.

Regional Characteristics of Municipal Waste
Švarc, Vít ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
This thesis describes the current state of waste management in Czech Republic and assesses the impact of small businesses on the production of municipal waste in various Czech regions. The main objective of this thesis is to create a model of production of municipal waste with a focus on so-called commercial waste or an industrial waste, which is part of the waste, produced from municipal waste management systems. The work is based on statistical data of municipal waste production, statistics on the representation of small-scale industries of the Czech municipalities, and uses correlative and regressive analyses.

Compliance Algorithms in dynamic service oriented systems
Šabatová, Ivana ; Doucek, Petr (advisor) ; Ivánek, Jiří (referee) ; Kreslíková, Jitka (referee) ; Gregor, Jiří (referee)
Compliance achievement and assurance of processes and services with regulatory requirements, standards, and business requirements becomes an actual task that should be resolved already in the stage of information systems design and implementation. If the particular business process or business service is supported with an IT system, then the compliance assurance relates also to this supporting system. This dissertation thesis presents the concept of continual compliance management in service oriented systems with a special focus on application of advanced process automation tools. The aim of this thesis was design of methods and procedures for reliability and credibility of business processes both internally in single domain, and in case of business process outsourcing including iterated and/or dynamic outsourcing i.e. in multi-domain environment with a special emphasis on automation level maximization. Particular process and/or service is considered to be reliable and credible if we are able to prove its compliance with the defined requirements in a trusted way. The first part of this thesis is dedicated to traditional methods for compliance achievement and assurance as a basis and inspiration for methods based on high level of automation. The second part of this thesis presents the concept of design, implementation and verification of compliance in service oriented systems. It introduces the terms of ideal target process, Key Assurance Indicator (KAI) and Key Security Indicator (KSA). For multi-domain environment there is the concept of Protection Level Agreement (PLA). This part also covers a new method of business process analysis designed for their automation as well as a concept of business rules design, testing and automation integration. The third part named Conceptual Model of Compliance Assurance in BPMS and Service Oriented Systems Environment brings a method inspired by well-known Deming Cycle (Plan, Do, Check, Act), description of the notations selected for compliance algorithm and target process modelling, and first of all the compliance algorithm design. This concept is demonstrated on two case studies of real business processes analyzed in Hospital San Raffaele in Milan, Italy. First of them is an internal business process regulated by regional law, the second study is an example of compliance with business requirement achievement and assurance in multi-domain environment of iterated dynamic outsourcing. These case studies were verified by simulation with subject matter experts and business process activities performers of the hospital personnel.
