GHG emissions reduction based on a heuristic optimization approach
Dejan Dragan, Klemen Prah, Tomaž Kramberger, Maja Fošner, 2013, published scientific conference contribution

Abstract: Since the transport causes about 26% of global CO2 emissions, the need to reduce greenhouse gas emissions (GHG) is becoming increasingly necessary. To achieve this objective, several approaches were adopted, like for example the employment of alternative sustainable technologies, or the enforcement of changes in driving skills. In contrast with this kind of approaches, an interesting approach is to reduce the vehicle miles of travel (VMT). In this paper, the concept of VMT reduction based on a heuristic optimization approach is introduced. The suitability of this concept has been tested for the School Bus Routing Problem (SBRP). Working mechanisms of the adopted heuristic optimization algorithms are briefly explained. As can be seen from the results, the optimization of bus stops, bus routes and driving schedules can significantly reduce the amount of VMT and consequently the amount of CO2 emissions.

The development of four-year-old child's competences with the help of information-communication technology
Jurka Lepičnik-Vodopivec, Pija Samec, 2012, original scientific article

Abstract: Nowadays it is very difficult to avoid the information-communication technology. It is present everywhere: in the business world, civil services, education, at home. The ability to search, choose and use relevant data and information among endless choices, offered by the modern technology, is also seen as a key competence. This article presents the influence which the ICT has on the development of four-year-old children's competences. The present issue is a part of an extensive study which also deals with children's access to the ICT and its usage at home. The data was gathered with the help of 130 parents, who filled out a questionnaire and provided us with their opinions about their children's usage of the ICT at home. We discovered that the ICT influences the development of certain competences to some extent. We also tried to see if there are any differences based on the child's gender and parents' level of education.

Children and virtual reality
Jasminka Zloković, Metod Černetič, Olga Dečman Dobrnjič, 2009, original scientific article

Abstract: Possible responses to the extremely complex and delicate question of the influence that exercises on the development of a child as a unique personality, on the child's psycho-social development and on the education of a child generally may be provided by serious research of a cohort sequential design, either in research programmes in the field of educational sciences or of other social disciplines. The present paper confronts some dilemmas of the modern world. Particularly those between the educational values, families and schools and education supplied (imposed) by virtual reality that promotes the social standardization of behaviour and the perception of values and of the world around us. The aggressiveness of the mass media in presenting as and without an often results in a virtual life for a child, with virtual friends, education and even virtual families. In the time of developing technology, an important question arises: how to deal with such a situation. Do we direct young people to carefully select from what modern virtual reality has to offer and how do we do that?

Interactive learning environment for children in the beliefs of pre-school teachers
Magdalena Grochowalska, 2014, short scientific article

Abstract: The following academic article is based on a PhD thesis that is currently being completed, titled Education and Qualifications of Elementary School Teachers in the U.S. State of Kansas and Slovenia for teaching in classes with immigrant children. The research study titled Integrating Multicultural Subject Matters into Teaching Strategies of Elementary School Teachers (The U.S. State of Kansas), conducted in 2007 based on a sample of 89 elementary school teachers in the U.S. State of Kansas, represents one aspect of assessing the adequacy of undergraduate education regarding multicultural subject matters for elementary school teachers in Slovenia and the U.S. (State of Kansas) as well as the qualifications of elementary school teachers of both countries for working with immigrant children. Despite the long-standing tradition of multicultural education in western countries, the research results for Kansas elementary school teachers showed a presence of significant discrepancies between the actual and optimal integration of multicultural subject matters. These results indicate that future undergraduate study programs will have to invest more time in developing multicultural skills and providing practical experiences for working in a diverse environment.

Social presence and interaction in learning environments
Ines Kožuh, Zoran Jeremić, Andrej Sarjaš, Julija Lapuh Bele, Vladan Devedžić, Matjaž Debevc, 2014, original scientific article

Abstract: With the increased use of social media there is a growing interest in using social interaction and social presence in education. Despite this phenomenon, no appropriate methodology was found on effective integrating of both concepts into online learning. In this study, we propose integrating two different kinds of learning tools to provide social interaction and social presence in Personal Learning Environments. We have evaluated the proposed concept in a classroom setting, using a specific social interaction tool and a specific social presence tool. The findings revealed that although the use of the social interaction tool was positively associated with students% academic success, the perceived ease of using the social presence tool was negatively related to students' success.

Highly divergent Clostridium difficile strains isolated from the environment
Sandra Janežič, Mojca Potočnik, Valerija Tkalec, Maja Rupnik, 2016, original scientific article

Abstract: Clostridium difficile is one of the most important human and animal pathogens. However, the bacterium is ubiquitous and can be isolated from various sources. Here we report the prevalence and characterization of C. difficile in less studied environmental samples, puddle water (n = 104) and soil (n = 79). C. difficile was detected in 14.4% of puddle water and in 36.7% of soil samples. Environmental strains displayed antimicrobial resistance patterns comparable to already published data of human and animal isolates. A total of 480 isolates were grouped into 34 different PCR ribotypes. More than half of these (52.9%; 18 of 34) were already described in humans or animals. However, 14 PCR ribotypes were new in our PCR ribotype library and all but one were non-toxigenic. The multilocus sequence analysis of these new PCR ribotypes revealed that non-toxigenic environmental isolates are phylogenetically distinct and belong to three highly divergent clades, two of which have not been described before. Our data suggest that environment is a potential reservoir of genetically diverse population of C. difficile.

Danube Region Entrepreneurship Observatory
Polona Tominc, Miroslav Rebernik, Barbara Bradač Hojnik, Karin Širec, scientific monograph

Abstract: There is no doubt about the importance of multi-country studies of entrepreneurial activity in enabling the comparison and replication of research and generating meaningful contributions to scholarship, practice and policy. This international comparison perspective is especially important when processes in each single economy are analysed against the broader global, European or regional environment. Since entrepreneurship is a complex social phenomenon, several dependencies can be understood only with comprehensive research that includes continuous positioning of national entrepreneurship in the European and global perspectives. Within Global Entrepreneurship Monitor (GEM) it is possible to compare data for more than 100 countries not only in the field of early-stage entrepreneurial activity but also in areas such as general attitudes of the adult population towards entrepreneurship, entrepreneurial intentions, etc. In this scientific monograph publication, we analyse the entrepreneurial profiles of Danube region countries, entrepreneurial intentions in the region and investigate the competition and aspirations of early-stage entrepreneurs in these countries.

A new method for determining extra time by considering ergonomic loads in the garment and metal working industries
Vekoslav Verhovnik, Andrej Polajnar, 1993, original scientific article

Abstract: The changing labour conditions in the garment and metal-working industries have led to the necessity of determining new extra times to establish the time standard. In this paper, a method of measuring stress and strain imposed upon the operator in new working conditions by determining the additional production coefficient is presented. The method gives criteria and grades to assess stress at the workplace. Physical stress (dynamic and static), thermal and visual stress, discomfort caused by noise, aerosols, gases and vapours, and the stress due to monotony are assessed. The stresses are expressed by ecological, physiological and psychological indexes. The indexes are pondered. Ponderation includes the factor of the magnitude and the time of exposure to stress. Ponderation is expressed by the number of points, the total being an adequate presentation of the stresses. Stress and strain decrease the working performance of the operator. Therefore they must be included in the standard to compensate for the operator's lower working efficiency due to physical and psychological strain at the workplace, Short breaks and stops allowed during work enable the operator to perform work tasks without getting excessively tired. The necessary correction of the production time is made by applying the ergonomic coefficient Ker.
