The increasing use of online services in societies makes this area more relevant than before. It is the task of educational institutions to prepare their students for a safe online life. At our universities, we have decided to focus on this area. Before planning the necessary curriculum, we conducted a survey among university students to find out which areas of this field require more attention in privacy awareness education. In this paper, we present the results of this survey. Multiple-choice questions were used in the questionnaire, where students had to choose between good, most often chosen wrong, and random wrong answers. We found that in many cases the students chose the well-known wrong answers, which means that we have to deal not only with useful information but also with misconceptions in the course material. Based on these results, we designed a VR environment using the results of this survey. This VR environment includes a curriculum on privacy awareness that deal with those fields that students need to study. This environment is designed for self-paced learning as a supplement to university education and developed in a MaxWhere space.

Subgraph isomorphism checking (an NP-complete problem) is a regular operation with this kind of data. In this paper, we propose an improve-ment of Ullmann algorithm, a well-known subgraph isomorphism checker. Our new algorithm is called Ullmann-ONL. It utilizes a novel sorting method for query vertices and L-levels of vertex neighborhoods (NL) to confine the search space of Ullmann algorithm. Our performance study shows that Ullmann-ONL outperforms previously proposed algorithms with a wide margin. LA - English DB - MTMT ER - TY - CHAP AU - Novac, O.C. AU - Novac, C.M. AU - Ciora, B.

An overview regarding the mobile technologies, in general but also a close look at two major mobile development frameworks, which are Ionic and Flutter. They are being analyzed at an individual level and furthermore, a comparison between these two technologies is taking place.

We launched VR courses and created immersive VR environments to provide curricula for our students. Based on VR courses and available curricula, students can choose thesis topics in this field at the end of their BSc studies. During the thesis work, they have to design and create a thematic environment with an immersive VR software: the MaxWhere 3D platform. Students come to the thesis work with different prior VR experiences: Most of them encountered VR in a learning environment, i.e., they had university courses on VR or had and used curriculum in a VR environment. However, there are those who come to the thesis work without learning about VR, learned from games only about VR. Our assumption was that students in the 21st-century generation have a sense of “VR thinking” so they can seamlessly switch between the real and virtual 3D worlds. Experience has shown that this operation is not trivial for all of them. To determine the range of difficulties in thinking in VR and to explore the causes of the problems, we used the method of a personal interview survey among students. The survey found that students who did not encounter VR in an educational setting were much less able to think creatively in VR. The level of creative thinking in VR was also lower for those who had already played VR games anyway. To develop creativity in thinking about VR, we presented key information on the thesis work in a VR environment to students who plan to work in VR. Experience to date has shown positive effects in developing creative VR thinking. In this paper, we present our experiences concerning the students’ thesis work on the use of VR as a framework as well as the results of the survey.
