The textbook "Structure and reactivity - solved examples and tasks, part 1" is the basis for teaching the subject "Structure and reactivity" for students of the 1st year of master's studies at the Faculty of Science, UPJŠ, department of Organic Chemistry. The textbook is divided into individual chapters, each chapter offering students examples of chemical reactions, where their course is explained on the basis of appropriate reaction mechanisms. A substantial part of the textbook consists of unresolved tasks, the main goal of which is the development of students' knowledge and skills. Due to the fact that the textbook is focused on only one semester of study, it cannot cover all reactions, rather it is only representative examples of different types of reactions, such as: addition reactions, elimination reactions, aromatic substitution, addition-elimination reactions, radical reactions and pericyclic reactions.

The learning material for the course Practice in Immunology is based on several years of experience with teaching this subject, but mainly to provide students from the Biology Department at the Faculty of Natural Sciences, UPJŠ in Košice with sufficient theoretical background for practical exercises. It also serves as a scientific diary for detailed recording of all experimental data necessary for preparing laboratory protocols from individual exercises.

In studying biology, it is essential that students thoroughly understand not only the basics of each discipline but also acquire practical skills, including designing scientific experiments, selecting appropriate analytical/investigative techniques up to interpreting and presenting experimental data. The goal of this new publication is therefore to provide master's students with a practical study guide that supports and expands their knowledge about basic immunology principles.

Súčasná výučba chémie má svoje špecifické problémy. Na jednej strane sa v dôsledku posunutia ťažiska učiva chémie v prospech učiva teoretického, zvýšila náročnosť učiva chémie a v súvislosti s tým, sa znížil záujem žiakov o chémiu. Nezáujem žiakov o chémiu je najviac podporovaný názorom, že je to práve chémia, ktorá výrazne prispieva k zhoršovaniu kvality životného prostredia. Na druhej strane žijeme v dobe, keď sa s produktami chémie stretávame prakticky všade. Nutné je spoznať základy chémie čo najlepšie, preto je otázka zvýšenia záujmu o výučbu chémie a zvýšenia jej účinnosti veľmi aktuálna.
Do slovenských škôl vstúpili štátne vzdelávacie programy ako základ pre tvorbu školských vzdelávacích programov. Tu je kladený dôraz nielen na získavanie určitej sumy znalostí, ale na vytváranie a rozvíjanie kľúčových a špecifických kompetencií žiakov, na ich prípravu pre celoživotné vzdelávanie a uplatnenie sa v živote. Preto je stále väčšia pozornosť venovaná jednému zo základných didaktických prostriedkov pre zvýšenie aktivity žiakov vo výučbe, a tým aj zvýšenie efektívnosti výučby chémie – učebným úlohám.
Z teórie aj z praxe výučby chémie vieme, že učebné úlohy, otázky, príklady, cvičenia atď., sú jednými z dôležitých súčastí každej vyučovacej hodiny. Učebné úlohy sa uplatňujú vo všetkých fázach výučby – vo fáze motivačnej, vo fáze osvojovania učiva, vo fáze upevňovania učiva a vo fáze kontroly osvojeného učiva. Je teda zrejmé, že každý učiteľ sa ocitne skôr či neskôr v situácii, keď bude musieť učebné úlohy vyberať z učebníc, pracovných zošitov, zbierok a príkladov, alebo ich tvoriť sám.
Vedecká monografia je určená pedagogickým odborníkom i učiteľom chémie, ktorá ich má zoznámiť s ukážkami rôznych typov a foriem učebných úloh a so základmi ich tvorby v chémii a môže byť pre nich nápomocná pri tvorbe atestačných prác zameraných na tvorbu testov a ich štatistické vyhodnotenie.

The university textbook deals with the latest knowledge from the systematics of vascular plants in a clear manner. Vascular plants arose in the Silurian period in the Paleozoic, when the first primitive plants moved from water to dry land, which required evolutionary progress in the morphological and anatomical structure of these plants. During about 420 million years of the existence of vascular plants, several of their main groups have evolved: the spore vascular plants, including the lycopods (branch Lycopodiophyta) and group of ferns and related plants (branch Monilophyta), and the seed plants, including gymnosperms (branch Gymnospermae) and angiosperms ( Angiospermae), which currently dominate among plants. The textbook provides a brief but comprehensive overview of the main groups, orders and families of plants with their description, distribution, main representatives, while also addressing the useful properties of selected species. The work is complemented by an overview of the system of plants by Cronquist, Tachtadžjan, APG and an overview of the families of the Slovak flora, as well as a taxonomic index.

The textbook "Bioenergetics" should serve as an introduction to the study of bioenergetics. This field of science is currently highly actual, as the results of the bioenergetics research in recent years clearly show that bioenergetics processes in living systems can "serve" not only to transformation of energy, but also affect the course of processes such as apoptosis, aging, origin and development of many diseases (especially neurodegenerative).

These facts clearly indicate the need for the existence of quality teaching texts that would allow students to acquire the necessary information and knowledge in this scientific discipline in an acceptable way. For the above mentioned reasons, we decided to create these textbooks, which are in the form of ten chapters, which naturally and logically follow each other.

Machine learning addresses the issues of how computer programs recognize complex patterns and make decisions based on data. In these university textbooks, we focus on theoretical knowledge in the field of machine learning in which we present the creation of concepts for objects, the preparation of concepts, hypotheses and the process of learning from examples. We describe Boolean formulas and their representations, probabilistic learning, linear and logistic regression, linear modeling and classification. Clustering and the Bayesian approach to machine learning conclude this publication.

University textbooks are intended for students of master's degree programs in computer science.

Over the past fifteen years, the course on ’Exactly Solvable Models in Statistical Physics’ has become an indispensable ground of the study programme ’Theoretical Physics’ at Faculty of Science of Pavol Jozef ˇSaf´arik University in Koˇsice. At first, the course based on the first edition of this textbook was intended for undergraduate students only, however, I have later prepared follow-up course taught at a postgraduate level on demand of several ambitious students who wished to continue in studying this exciting research field. It is already more than decade when our students enrolled in the study programme ’Theoretical Physics’ graduate from ’Introduction to Exactly Solvable Models in Statistical Physics’ at a master level and ’Exactly Solvable Models in Statistical Physics’ at a postgraduate level. Of course, it was necessary somehow to rearrange topics for the courses of undergraduate and postgraduate students. More specifically, a few more challenging topics concerned with exact solutions of 2D Ising model (chapter 3) were moved to a more advanced course intended for the postgraduate students, while an introductory course intended for the undergraduate students was contrarily supplemented with a few new topics requiring the second edition of this textbook. The second edition of this textbook thus contains a completely new chapter 4 devoted to the exact solution of the Ising model on the Bethe lattice using the method of exact recursion relations, while the chapter 5 was supplemented by exact results for ground state of a few frustrated Heisenberg spin models using the variational method. It is my hope that the next edition of this textbook will come soon and it will involve all topics specifically taught within the postgraduate course as well.
