Each subject needs learning materials, so that each professor prepares lectures and exercises himself. We posted our materials on Moodle platform and on e-library system. At e-library we upload our books and scripts for the subject, but on Moodle we have freedom to post videos, some simulation, open codes, images, text documents, ppt presentations. The students also have the freedom to search and find additional learning materials such as text documents, videos, and images with the aim of making it easier to master and understand the lesson. For that purpose, we had some discussions with our students to define what and how they prefer to learn. We need that discussion because we appreciate the opinion of our students to prepare better learning materials. [ABSTRACT FROM AUTHOR]

In this paper, the attitude of the students towards learning of fundamentals of electrical engineering and their professor is considered. For this purpose, a survey of first-year students studying this subject was conducted. The survey was conducted on two generations of students from the academic year 2020/2021 during the COVID-19 pandemic and 2022/2023 generation after the pandemic. Our goal is to see students’ opinion about the teaching process and the professor and determine if there is a difference in the students' opinion. It should be noted that during the COVID-19 the teaching took place online, and after the COVID-19 with physical presence. Students during the COVID-19 period gave lower ratings for their professors and found the colloquiums more difficult, expressing less satisfaction with the lectures and exercises. Their colloquium results were also worse. Additionally, final exam results showed that a higher percentage of students from academic years with physical presence passed the exams.

The most severe and pervasive problems in modern healthcare systems occur during epidemics and pandemics. One of these problems is the reassignment and the rescheduling of the medical staff during the days of the critical weeks with a high number of infected patients, which, at the same time, amplifies the need for hiring additional medical staff. In this paper we are addressing the problem of the number of additional nurses that must be hired as part time workers, with the following objective: to satisfy the minimum number of nurses needed during the days of the critical weeks, while keeping the hospital costs as low as possible. The solution of this problem is obtained by a schedule of the additional personal based on four, partially overlapping shifts, which gave a reduction of the initial costs. It can be applied in any organization that is in need for additional staff, regardless of the reason. [ABSTRACT FROM AUTHOR]

One of the most used statistical techniques that include machine learning and data mining for predicting future outcomes with help of data that already exist is known as predictive algorithm. Predictive models are not stable, and they build assumption based on past and present actions. In the paper we are going to introduce Amazon online store and how algorithms know what we like, so they can recommend products to us by their own. One of the biggest innovations in online shopping - first introduced by Amazon - was automatic recommendation generation. The more accurate prediction algorithms are, the more online stores will sell their products. For that reason, prediction algorithms are of great significance for online stores.

The rapid development of technology has made the availability of many ICT tools easy. In that way, their application in education became possible. So, various ICT tools began to be applied in the teaching process in many subjectsand mathematics was no exception. In this paper we will state which ICT tools can be used in teaching mathematics. Then we will state the results of a research on the advantages of using ICT tools in teaching mathematics, conducted among students from the ninth grade in primary school "GoceDelchev" in Sveti Nikole. And finally, the conclusion about the advantages and disadvantages of using ICT tools will be given. In the conclusion we mainly point out that the application of ICT tools in teaching mathematics contributes to facilitating learning, increasing the desire to solve mathematical tasks, raise the teaching process to a higher level and also motivate students to work and learn more independently.

In this paper, we will prove a theorem for a functional where we prove that the necessary condition for the extreme of a functional is the variation of the functional to be equal to zero and we will give an example of its application, the problem of the Plateau. [ABSTRACT FROM AUTHOR]

Every new generation of students have difficulties with learning mathematical subjects. The success in Mathematics is getting lower and lower, not only in Macedonia but also on global level. Mathematical materials that contain only problems with solutions without their visual representation are hardly acceptable for many students. So, visualization plays an important role in the process of teaching mathematics subjects. In this paper, we will present the solution of examples of plane equation and, by using free software, visualization of that solution is made. For solving several examples, we are going to use the Computer Algebra System (CAS) in GeoGebra. [ABSTRACT FROM AUTHOR]
