The training and adaptation of new principals of educational institutions for work in educational establishments. Annotation. The research focuses on the beginning of the career of principals of educational institutions, its implicative factors, the most characteristic problems and their solutions. As a result, a set of competencies for principals in the era of new economics have been formulated, a conceptual statements and model of principals’ education have been formed, an evaluation of the model by experts has been conducted. The author has developed suggestions for state institutions for the selection, training and grooming of new principals of educational institutions, for organising support for them, as well as suggestions for pretenders to the post of a principal and for new principals of educational establishments

Robot Control Using Inductive, Deductive and Case Based Reasoning

The paper deals with a problem of intelligent system’s design for complex environments. There is discussed a possibility to integrate several technologies into one basic structure that could form a kernel of an autonomous intelligent robotic system. One alternative structure is proposed in order to form a basis of an intelligent system that would be able to operate in complex environments. The proposed structure is very flexible because of features that allow adapting via learning and adjustment of the used knowledge. Therefore, the proposed structure may be used in environments with stochastic features such as hardly predictable events or elements. The basic elements of the proposed structure have found their implementation in software system and experimental robotic system. The software system as well as the robotic system has been used for experimentation in order to validate the proposed structure - its functionality, flexibility and reliability. Both of them are presented in the paper. The basic features of each system are presented as well. The most important results of experiments are outlined and discussed at the end of the paper. Some possible directions of further research are also sketched at the end of the paper

A Proposed Structure of Knowledge-Based Hybrid Intelligent Systems for Sophisticated Environments

The paper deals with a problem of intelligent system’s design for complex environments. There is discussed a possibility to integrate several technologies into one basic structure. One possible structure is proposed in order to form a basis for intelligent system that would be able to operate in complex environments. The basic elements of the proposed structure have found their implemented in software system. This software system is shortly presented in the paper. The most important results of experiments are outlined and discussed at the end of the paper. Some possible directions of further research are sketched

Knowledge-based Robot Control

The paper is related with the problem of developing autonomous intelligent robots for complex environments. In details it outlines a knowledge-based robot control architecture that combines several techniques in order to supply an ability to adapt and act autonomously in complex environments. The described architecture has been implemented as a robotic system that demonstrates its operation in dynamic environment. Although the robotic system demonstrates a certain level of autonomy, the experiments show that there are situation, in which the developed base architecture should be complemented with additional modules. The last few chapters of the paper describe the experimentation results and the current state of further research towards the developed architecture

Self-service Ad-hoc Querying Using Controlled Natural Language

The ad-hoc querying process is slow and error prone due to inability of business experts of accessing data directly without involving IT experts. The problem lies in complexity of means used to query data. We propose a new natural language- and semistar ontology-based ad-hoc querying approach which lowers the steep learning curve required to be able to query data. The proposed approach would significantly shorten the time needed to master the ad-hoc querying and to gain the direct access to data by business experts, thus facilitating the decision making process in enterprises, government institutions and other organizations.Comment: 13 pages, 4 figures, 2 tables, accepted for publication in the 12th International Baltic Conference on Databases and Information Systems 201

LC-MS based quantification of 2’-ribosylated nucleosides Ar(p) and Gr(p) in tRNA

RNA nucleosides are often naturally modified into complex non-canonical structures with key biological functions. Here we report LC-MS quantification of the Ar(p) and Gr(p) 2'-ribosylated nucleosides in tRNA using deuterium labelled standards, and the first detection of Gr(p) in complex fungi

The Stranger Within: Dostoevsky's Underground

In Fyodor Dostoevsky’s influential novel Notes from underground, we find one of the most memorable characters in nineteenth century literature. The Underground Man, around whom everything else in this book revolves, is in some respects utterly repugnant: he is self-centred, obsessive and cruel. Yet he is also highly intelligent, honest and reflective, and he has suffered significantly at the hands of others. Reading Notes from underground can be a harrowing experience but also an educative one, for in an encounter with what at first seems unfamiliar and disorienting we can awaken the ‘stranger within’. Dostoevsky’s work, if we are ready for it, can shake us from our slumbers and allow us to see that what appears to be strange may in fact be deeply familiar to us
