Early spread of COVID-19 in Romania: imported cases from Italy and human-to-human transmission networks
Marian-Gabriel Hâncean, Matjaž Perc, Jürgen Lerner, 2020, izvirni znanstveni članek

Opis: We describe the early spread of the novel coronavirus (COVID-19) and the first human-to-human transmission networks, in Romania. We profiled the first 147 cases referring to sex, age, place of residence, probable country of infection, return day to Romania, COVID-19 confirmation date and the probable modes of COVID-19 transmissions. Also, we analysed human-to-human transmission networks and explored their structural features and time dynamics. In Romania, local cycles of transmission were preceded by imported cases, predominantly from Italy. We observed an average of 4.8 days (s.d. = 4.0) between the arrival to a Romanian county and COVID-19 confirmation. Furthermore, among the first 147 COVID-19 patients, 88 were imported cases (64 carriers from Italy), 54 were domestic cases, while for five cases the source of infection was unknown. The early human-to-human transmission networks illustrated a limited geographical dispersion, the presence of super-spreaders and the risk of COVID-19 nosocomial infections. COVID-19 occurred in Romania through case importation from Italy. The largest share of the Romanian diaspora is concentrated especially in the northern parts of Italy, heavily affected by COVID-19. Human mobility (including migration) accounts for the COVID-19 transmission and it should be given consideration while tailoring prevention measures.

Opis: Novel coronavirus disease (COVID-19), named a pandemic by the WHO, is the current global health crisis. National and international collaboration are indispensable for combating COVID-19 and other similar potential outbreaks. International efforts to tackle this complex problem have led to remarkable scientific advances. Yet, as a global society, we can and must take additional measures to fight this pandemic. Undoubtedly, our approach toward COVID-19 was not perfect, and testing has not been deployed fast enough to arrest the epidemic early on. It is critical that we revise our approaches to be more prepared for pandemics as a united body by promoting global cooperation and commitment.

City size and the spreading of COVID-19 in Brazil
Haroldo V. Ribeiro, Andre S. Sunahara, Jack Sutton, Matjaž Perc, Quentin S. Hanley, 2020, izvirni znanstveni članek

Opis: The current outbreak of the coronavirus disease 2019 (COVID-19) is an unprecedented example of how fast an infectious disease can spread around the globe (especially in urban areas) and the enormous impact it causes on public health and socio-economic activities. Despite the recent surge of investigations about different aspects of the COVID-19 pandemic, we still know little about the effects of city size on the propagation of this disease in urban areas. Here we investigate how the number of cases and deaths by COVID-19 scale with the population of Brazilian cities. Our results indicate small towns are proportionally more affected by COVID-19 during the initial spread of the disease, such that the cumulative numbers of cases and deaths per capita initially decrease with population size. However, during the long-term course of the pandemic, this urban advantage vanishes and large cities start to exhibit higher incidence of cases and deaths, such that every 1% rise in population is associated with a 0.14% increase in the number of fatalities per capita after about four months since the first two daily deaths. We argue that these patterns may be related to the existence of proportionally more health infrastructure in the largest cities and a lower proportion of older adults in large urban areas. We also find the initial growth rate of cases and deaths to be higher in large cities; however, these growth rates tend to decrease in large cities and to increase in small ones over time.

Research data and software for paper Forecasting COVID-19
Matjaž Perc, Nina Gorišek Miksić, Mitja Slavinec, Andraž Stožer, 2020, izvirni znanstveni članek

Opis: The World Health Organization declared the coronavirus disease 2019 a pandemic on March 11th, pointing to the over 118,000 cases in over 110 countries and territories around the world at that time. At the time of writing this manuscript, the number of confirmed cases has been surging rapidly past the half-million mark, emphasizing the sustained risk of further global spread. Governments around the world are imposing various containment measures while the healthcare system is bracing itself for tsunamis of infected individuals that will seek treatment. It is therefore important to know what to expect in terms of the growth of the number of cases, and to understand what is needed to arrest the very worrying trends. To that effect, we here show forecasts obtained with a simple iteration method that needs only the daily values of confirmed cases as input. The method takes into account expected recoveries and deaths, and it determines maximally allowed daily growth rates that lead away from exponential increase toward stable and declining numbers. Forecasts show that daily growth rates should be kept at least below 5% if we wish to see plateaus any time soon - unfortunately far from reality in most countries to date. We provide an executable as well as the source code for a straightforward application of the method on data from other countries.

Young pedagogical centre with extensive experience and knowledge
Boris Aberšek, 2009, izvirni znanstveni članek

Opis: The contributions gathered in this publication have been prepared within the framework of the Pedagogical Center (PC) of the Faculty of Natural Sciences and Mathematics (FNM) at the University of Maribor, which might seem to be a young center since it has only been established in 2009, nevertheless, the extensive experience and knowledge of its faculty tell a story of a much more established institution. “Pedagogical” is a defining term indicting that the center's activities are focused primarily on pedagogical programmes at FNM and on educating teachers at all levels in the broadest sense of the word. Pedagogical center FNM is a pedagogical research unit, that supports all natural science, mathematical and technology programmes at both the Faculty of Natural Sciences and Mathematics, as well as the entire University of Maribor, especially the teaching programmes, since after the separation of the large Faculty of Education into three entities - FNM being one of them - its “colour” as well as educational and historical core have been lost. Teacher education at FNM lost previous value and has become much less emphasised than it was the case with its predecessor institution the Faculty of Education. Thus the main aim of the center is to give back to the faculty a part of its previous “colour” as well as to promote and develop educational sciences and their interdisciplinary integration that will certainly mean a step towards guaranteeing quality of work as well as quality of education for all students.

What is the tendency in biology virtual field trips?
Miro Puhek, Matej Perše, Andrej Šorgo, 2012, izvirni znanstveni članek

Opis: There is no doubt any more that virtual worlds are suitable for school environment. It was shown by various researchers that they can contribute in supplying students with additional information, help them to visualise subjects, respond with answer on demand or even in some cases supplement the real materials. Based on the real experience, the virtual field trail Walk on Maribor Island was developed for biology and natural science classes in lower secondary school. The trail is presented through eight exercises that differentiate not only in theme, but also in difficultness, fun, background idea etc. In spring 2011, 133 eighth grade students worked on the virtual field trail during the biology class. After the work on exercises, students were asked to analyse the exercises regarding the level of difficultness, level of interest and level of proficiency. The main aim of the study was to present the tendency in biology virtual field trips that should be taken into consideration before the development of new exercises.

Using chemical models for developing natural science competences in teaching chemistry
Darinka Sikošek, Mateja Žuželj, 2013, izvirni znanstveni članek

Opis: Chemical models are indispensable tool in chemistry class and enable secondary school pupils to develop complex thought processes and spatial concepts, both of which are necessary to improve their understanding of chemical concepts. In this research, special emphasis is given to complex competencies not only their acquisition, but rather how pupils develop them. For this purpose, a learning strategy has been developed, called learning by self-generating chemical models. Pupils learn individually on their own models, which are made from easily accessible, low-cost materials. The impact of workable models was investigated (assembly of commercial models and production of self-made models) on the (1) learning success using simple molecule shapes and (2) the degree of competence development which realized through the implemented activities. The study involved first-year secondary school-pupils, defined as self-creators of paper- and -wire models (experimental group) and assemblers of commercial models (called the control group). The appearance of the molecules being studied took the form of geometric shapes and structures, which pupils present by making of ball-, called wire-models from plasticine and wire or paper created, called paper models. Based on the results of statistical processing of the data, we found that self-creation of models (as an innovative approach) leads to better understanding and to subsequently sustained knowledge for the pupil. It should also be noted that pupils who were self-generators in comparisons to those who merely assembled the models, generally developed many complex skills in the areas of problem solving, practical competence, mathematical competence and critical thinking skills. The knowledge so acquired was also better understood.

The challenges of complete informatization of education
Magdalena Šverc, Igor Pesek, Andrej Flogie, 2014, izvirni znanstveni članek

Opis: Since the methods of teaching and learning are currently changing, Slovenian society is challenged to respond. Ministries responsible for the development of the educational system encourage informatization of education by launching strategically oriented tenders. This research presents three such projects, which together propose guidelines on how to further develop the Slovenian educational system with an emphasis on the introduction of information and communication technologies into everyday life in Slovenian schools at all levels (teaching, learning, management, etc.). There are three main areas that are covered: (1) technical assistance and support, (2) development and deployment of e-learning materials and e-textbooks and (3) teacher training. Using these approaches it would be possible to achieve an increase in digital competences and a change in our pedagogical paradigm. Results show a better motivation, communication and improved teamwork among students. This is a consequence of changes in the way of thinking and teaching by both teachers and other school participants, especially the headmasters who put the student in the centre of activities. The whole process of school informatization depends on a coherent development of various fields. The focus is on a change of pedagogical paradigm and the consequential teacher and managerial staff training.

The architecture of a school system according to the theory of dynamical systems
Boris Aberšek, Janez Bregant, 2012, izvirni znanstveni članek

Opis: From the experience of recent years it seems clear that the existing educational system, as a whole, is perceived as an ailing system that fails to meet the needs of a major portion of the society it serves. Every aspect of the educational process must be studied and reconsidered in the light of new and different societal expectations. In the last decades we started with one school reform after the other, but it looks now that these changes had no positive impact whatsoever. Even worse, the school system was damaged afterwards. In this paper we will explore some possibilities how to improve it without facing these consequences. The main idea is, as a result of our latest research, that mathematical methods for describing and simulating could be very useful for predicting and simulating school systems without using a long term and complex empirical experimentation. The paper introduces the correlation between the dynamical mathematical calculus and the educational school system and elaborates to some extent the basic idea of using the former to predict the latter.
