Zborník abstraktov Študentskej vedeckej konferencie PF UPJŠ

Charakteristickou črtou vzdelávania na kvalitných vysokých školách, ku ktorým Prírodovedecká fakulta UPJŠ v Košiciach patrí, je úzke prepojenie vzdelávania a vedeckého výskumu. Poznatky a vedomosti z odboru štúdia získavajú študenti nielen teoretickým štúdiom jednotlivých disciplín, ale aj aktívnym zapojením sa do riešenia čiastkových vedeckých úloh v rámci výskumných tímov či už pri vypracovávaní záverečných prác alebo formou nástroja Študentských pomocných vedeckých síl (ŠPVS), ktorých činnosť sa na fakulte revitalizovala v roku 2015.

Študentská vedecká konferencia (ŠVK) je jedným z tradičných podujatí fakulty, ktoré je organizované počas Prírodovedeckých dní ako súčasť Sciencefestu. Svojou povahou prirodzene zapadá do spomínaného súkolia prepojenia vzdelávania a vedy a dlhodobo sa teší veľkej popularite a záujmu študentov. V roku 2016 na ŠVK vystúpilo 125 študentov Prírodovedeckej fakulty UPJŠ v Košiciach, v rámci 16 sekcií. Prehľad o zameraní a cieľoch študentských prác podáva tento zborník. Veríme, že bude inšpiráciou pre ďalších potenciálnych záujemcov o vystúpenie na ŠVK, ale bude zaujímavý aj pre širšiu verejnosť, ktorej môže podať doplnkový pohľad na činnosť fakulty.

The present textbook deals with exactly solved models and their diverse applications in several branches of physics such as mathematical physics, statistical physics, condensed matter physics and so on. Exactly soluble models are currently considered as an inspiring research field in its own right, which regrettably requires a considerable knowledge of sophisticated mathematics. Accordingly, my primary ambition was to provide an intro- ductory course for undergraduate students that would cover the simplest exactly solved models, whose rigorous solutions are available even after modest calculation. The present textbook should be therefore regarded as an auxiliary graduate-level textbook, which should serve as the student’s guide on this beautiful but surely intricate subject.

Even although I attempted to write largely self-contained textbook for undergraduate students, it is worthy of notice that the course on Exactly Solvable Models in Statistical Physics demands essential knowledges from the quantum mechanics, statistical physics, phase transitions and critical phenomena, which are its indispensable prerequisities. The most crucial fundamentals of these theories are briefly recalled in introductory remarks just for remembering and not for substituting those comprehensive courses. The rest of this textbook is entirely devoted to exactly solved lattice-statistical models with the main emphasis laid on their possible applications in the condensed matter physics. It is the author’s hope that the presented exact solutions are detailed enough in order to be easily followed by undergraduate students even without a support of tedious proofs, cumbersome theorems, longer argumentations, or obvious facts. This rather necessary compromise has of course a certain unadvisable impact on ’exactness’ of the presented solutions.

Finally, it is worthwhile to remark that the present textbook makes just a slight introduction into the simplest exactly solvable models and thus, the interested reader is referred for the follow-up study to several excellent books on exactly solved models quoted in the bibliography list on the next page. Note that the listed books were the major knowledge sources used by creating this textbook and they might be regarded as more advanced literature on this exciting research field.

Statistics is defined as a scientific discipline based on learning from data and on finding, controlling, and presenting uncertainty. In these university textbooks we present the history of statistics, basic concepts of statistical modeling, measurement of dependencies, regression models, analysis of variance. We describe simple sorting, multiple comparisons, assumptions of the ANOVA model, Kruskal-Wallis test.

University textbooks are suitable for students of mathematics and computer science at the first and second level of universities. Study materials are also suitable for students of non-informatics disciplines with a view to improving their knowledge and practical experience in the fields of informatics and provide an opportunity for students to apply in IT companies in solving practical tasks.

An important part of theoretical computer science is the problem of Turing machines. This computational model has two basic properties: like any other computational program, the software of a Turing machine is composed of instructions, but in its case they are all of a single type. Every other (so far known) computer program can be transformed into a Turing machine program without loss of information. While the second feature reduces the question of what a calculator cannot do to the question of what a Turing machine cannot do, the first feature allows a much simpler investigation of such a question. Using this computational model, we can thus find concrete problems that no automaton can ever deal with (perhaps the most famous is the problem of the Turing machine stopping). Their existence demonstrates the fundamental limitations of (not only ideal) computational means, and thus encourages both criticality and humility in our thinking.

The textbook is intended for university students who are preparing for the profession of biology teacher. The structure of the book is similar to an encyclopedia, with one page devoted to each content item, but the topics of the chapters and subchapters follow each other. The explanatory text on the page illustrates the diagram and there are notes and links to other sources of information. For better orientation, the content of the textbook is divided into 8 sections, which cover several chapters. It follows the general didactics, which it connects with the teaching of biological content. The book provides a basic orientation in the approaches to learning this subject, and also explains the relationship between biology as a science and the didactics of biology. It deals with teaching standards and curricula, advises on how to master biological concepts and understanding, how to communicate with students in biology classes, when and why are effective visual and practical methods. It acquaints the reader with the issue of setting goals for biological education in the cognitive, psychomotor and affective areas in relation to formative and summative assessment. Hopeful as well as experienced teachers will find in this publication not only a look into the history of teaching biology, but also a look into the future. Current trends in biology teaching, the connection of teaching with digital technologies, the virtual learning environment and interactive simulations and models belong to science lessons today.

Nanotechnology represent the fastest developing science in the present. They are based on the technologies that enable the matter manipulation at atomic level. Nanotechnology offer prepartion of the new materials with unknown and very specific properties and functions.Recent nanotechnology still stay in formative phase of their development. But more and more they are visible with nano-specific phenomenons in the fundamental control of the properties as well mater behaviour. This is quite possible that without nanotechnology will not work any science to the future, moreover that science will not exist anymore. Nanotechnolgy will give a chance and force to transform world to more environmental and comfortable. Expected is expansion of the nanotechnolgy to molecular nanosystems – heterogenous nets, in which molecules and supramolecules work as the nanodevices. The computers and robots will be reduced to the small and ultrasmall dimensions. In medicine will foremost the application of nanotechnology in genetic therapy and elimination of ageing. Nanosurgery will work at molecular level, cancer cells will be identified early and filtered , then substituted with healthy and unchanged. It is necessary to inform university or high school students  about principles of nanotechnolgy, preparation of the nanostructures, functionality of them and to offer full representation about molecular systems and nanodevices; the methods of nanostructures characterization and about application in miniaturized systems.

Tento vysokoškolský učebný text je určený študentom chemických a ekologických odborov na Prírodovedeckej fakulte Univerzity P. J. Šafárika v Košiciach a má poslúžiť ako pomôcka pre experimentálne cvičenie z koloidnej chémie. Koloidná chémia je významnou súčasťou teoretického základu chemických vied, patrí medzi novšie interdisciplinárne odbory prírodných vied. Spája poznatky z oblasti fyzikálnej chémie, fyziky a biológie, pričom využíva aj solídne znalosti z matematiky a ďalších vedných odborov. Pri pochopení problémov koloidnej chémie sú často nevyhnutné aj experimenty, ktoré modelujú predstavy o priebehu javov a zákonitostí, ktorými sa tento vedný odbor zaoberá. Preto je pre zvládnutie učebnej látky z koloidnej chémie také dôležité a podstatné aktívne absolvovanie experimentálneho cvičenia. Pri výbere úloh pre tieto skriptá bolo treba rešpektovať aj značné obmedzenia dané možnosťami laboratórne prístrojového a materiálového vybavenia nášho pracoviska. Napriek tomuto obmedzeniu však môžu študentom ilustrovať základné teoretické fyzikálno-chemické princípy koloidne disperzných sústav, a čo je dôležité – ich pochopenie môže prispieť k porozumeniu niektorých dôležitejších zvláštností koloidných javov.

In 2018, the Student Scientific Conference was held on April 18, 2018, in 16 sections covering biology and ecology, chemistry, physics, geography, mathematics, computer science, and their subject didactics. There were 110 registered contributions from bachelor's and master's students. Additionally, eight high school students participated outside of the competition; these students already visit our alma mater at a young age, work in our laboratories, and prepare for further studies under the guidance of our enthusiastic teachers. The day also included a programming competition and the IHRA competition in three categories, where students from PF UPJŠ competed alongside pupils from elementary and secondary schools.

The abstracts of the Student Scientific Conference contributions convincingly demonstrate that PF UPJŠ students study their field not only theoretically but also actively engage in solving partial scientific problems that are part of the research goals at PF UPJŠ institutes. This collection provides an overview of scientific activity at the faculty, which we believe will be interesting for the broader public as well.

The script „Základné laboratórne praktikum z anorganickej chémie“ builds on previous editions of the script, with some thematic units updated and supplemented with new knowledge, principles, and detailed work procedures.

This script is intended as a teaching aid for first-year students of the chemistry and interdisciplinary study programs at the Faculty of Science, Pavol Jozef Šafárik University in Košice. The introductory part of the volume acquaints students with safety regulations that they should follow during work in a chemical laboratory. Subsequently, in five chapters, basic laboratory techniques are described in detail, which students will use in the further part of the practices for preparing inorganic compounds. These chapters are enriched with illustrative images created using the freely distributable ACDFreeLabs 10 program or taken from literature listed at the end of the script. Some images were created by the authors, and others were taken from the catalog of Fisher Slovakia, s.r.o., which provided written permission for their use. The chapters describing the preparation of inorganic compounds are organized according to their composition, from simple elements or molecules, through binary compounds, acids, and salts, to complex compounds.

Within this subject, students should apply their theoretical knowledge gained during lectures on General Chemistry and Inorganic Chemistry and thereby acquire basic practical experience and skills that they will use in further studies.

The last two chapters were developed based on cooperation with Duslo a.s., Production Plant Strážske, which participates in the innovation of practical teaching through direct involvement of experts from practice as part of the KEGA project No. 008UPJŠ-4/2018.
