Predkladaný pracovný zošit na praktické cvičenia z cytológie je určený poslucháčom 1. ročníka bakalárskeho štúdia biológie a 1. ročníka bakalárskeho medziodborového štúdia v kombinácii s biológiou na Prírodovedeckej fakulte Univerzity Pavla Jozefa Šafárika v Košiciach. Slúži ako návod, ktorý má študentom uľahčiť prácu a umožniť rýchlejšiu orientáciu v zadanej úlohe. Úprava pracovného zošita do formy protokolov umožňuje študentom zakresliť vlastné pozorovanie a tým stimuluje študentov k presnejšiemu a trvalejšiemu zapamätaniu si precvičovanej úlohy a zároveň umožňuje spätnú kontrolu pedagógom. Počas cvičení sa študenti postupne oboznámia so základnými pojmami optiky, s aplikáciami využívajúcimi mikroskopickú techniku, ale aj so základnými rozdielmi medzi štruktúrou rastlinnej a živočíšnej bunky a ich organelami.

The publication is focused on discrete random processes, primarily on Markov chains, which have wide application in the field of economics and finance.

The textbook is divided into five chapters, the first of which serves as an introduction to random processes and provides definition, properties and classification of random processes in general. The second chapter discusses Markov chains with discrete time, including valuation of transitions between states and their optimal management. The third chapter focuses on special Markov chains with continuous time and emphasizes construction and solution to the system of Kolmogorov differential equations, which describe the dynamics of the process development. The last two chapters illustrate applications of Markov chains using examples of queuing system modeling and renewal theory.

Besides the explanation of basic terms, definitions and theorems with proofs, this textbook also provides number of solved examples to illustrate the discussed theory. Problem assignments are placed at the end of each chapter, so that readers can test their understanding of the content as they progress through the book. Solutions to all the problems and the list of references are provided at the end of the publication.

This textbook is primarily intented for students majoring in Economics and Financial Mathematics at the Faculty of Science of Pavol Jozef Šafárik University in Košice, and it covers content of the course “Random Proceses 1“ thought there. It might however serve also students from other schools in similar progams or professionals interested in this topic.

The presented text is devoted to the history of biology, medicine and pharmacy studies, as scientific disciplines, from ancient time, Middle age, and modern era. In the text are chronologically arranged the most important representatives of the history of the study of biological scientific disciplines, the basic characteristics of significant historical discoveries and the reassessment of their significance from the point of view of contemporary science of the 21st century.

Zborník abstraktov príspevkov účastníkov Študentskej vedeckej konferencie PF UPJŠ v Košiciach, ktorá sa konala 26. apríla 2017.

Už po piaty raz vychádza zborník zo Študentskej vedeckej konferencie (ŠVK) na Prírodovedeckej fakulte Univerzity Pavla Jozefa Šafárika v Košiciach. Teší nás, že ŠVK je pevnou súčasťou života fakulty a výkladnou skriňou kvality poskytovaného vzdelávania. V roku 2017 sa ŠVK konala v rámci tradičných Prírodovedeckých dní dňa 26. apríla 2017. Vystúpilo na nej 105 študentov Prírodovedeckej fakulty. Príspevky boli zaradené do 15 sekcií, ktoré navyše dopĺňala otvorená súťaž v programovaní, do ktorej sa zapojilo 17 študentov a finále súťaže IHRA, v ktorej súťažilo 27 tímov z celého Slovenska.

Abstrakty príspevkov prezentované v tomto zborníku dokumentujú, že na PF UPJŠ získavajú študenti poznatky a vedomosti zo svojho odboru nielen teoretickým štúdiom jednotlivých disciplín, ale aj aktívnym zapojením sa do riešenia čiastkových vedeckých problémov, ktoré sú súčasťou výskumných zámerov na ústavoch PF UPJŠ. Abstrakty príspevkov predstavujú svojim spôsobom aj prehľad o vedeckej aktivite na fakulte, ktorý, veríme, bude zaujímavý aj pre širšiu verejnosť.

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.

For computer scientists, the constant challenge is to seek efficient algorithms and various technical and implementation possibilities to improve the computational complexity of currently known algorithms. Partial solutions are offered by approaches such as grid-based methods and parallelization of computation. Quantum computers represent a significant but still unfulfilled promise. From a theoretical perspective, probabilistic and approximation approaches provide very effective solutions, and these are the methods we aim to explore in detail.

These electronic university textbooks serve as supplementary materials for the course Approximation and Probabilistic Algorithms. They were developed from the authors' materials and contributions by Prof. RNDr. Viliam Geffert, DrSc., whom the authors thank for providing the manuscript. Acknowledgments also extend to RNDr. Ján Katrenič, PhD., who prepared the first set of exercises for the course, and Žaneta Semanišinová, who reviewed large portions of the text and contributed suggestions for its improvement.
