Acceptance of GIS within ERP system : research study in higher education
Simona Sternad Zabukovšek, Polona Tominc, Zdenko Deželak, Gaik Nalbandyan, Samo Bobek, 2022, izvirni znanstveni članek

Opis: GIS is often used in companies where employees already use enterprise information systems/enterprise resource planning (ERP) systems and where both systems are used simultaneously. This article is a research study of GIS acceptance by users using GIS, not as a stand-alone tool, but as an integrated tool into the ERP system. The research was conducted using the Technology Acceptance Model (TAM), one of the most often used research models for researching behavioral intention and actual use of information systems. For this research study, TAM has been modified and extended with external factors. The main research objective is to identify determinants of GIS acceptance and the attitude of individuals toward using GIS integrated with ERP systems. The structural equation model with partial least squares (PLS) method was used to analyze collected survey data. The study researched 12 external factors in the TAM model, out of which 10 were found significant. The most important factors that impact behavioral intention to use ERP-GIS systems are perceived usefulness of ERP-GIS systems and attitude toward using GIS, followed by education and training about ERP-GIS systems and perceived enjoyment using ERP-GIS systems.

Electric vehicle charging stations coverage : a study of Slovenia
Klemen Prah, Mark Kmetec, Matjaž Knez, 2022, izvirni znanstveni članek

Opis: To promote the penetration of electric vehicles (EVs), it is of great importance to plan and construct charging stations rationally. In this sense, the state of Slovenia's charging station coverage was analysed. Using discrete and network geographic information system (GIS) models, with ArcGIS software, the density of electric vehicle charging stations (EVCSs), geographic distribution, nearness along a street network, and clustering analyses were performed. A survey conducted among Slovenian users of EVs supported the GIS analysis. It was found out that the distribution of EVCSs has an east-northeast to west-southwest directional trend. Only 13% of EVCSs are accessible from the nearest motorway at a distance of 500 meters or less. An insight into intrinsic clustering structure revealed 11 clusters of EVCSs from which the most distinct is the cluster on the area of Ljubljana. The scientific contribution of the research is in the integration of GIS, spatial analysis and the results of a survey to study the coverage of EVCSs in a certain region. Spatial analyses are carefully selected, and, in complementarity, give a comprehensive picture of EVCSs coverage. The research is important for further spatial planning of EVCSs.

Unlimited access to information systems with mobile devices : information security perspective
Igor Bernik, Blaž Markelj, 2011, pregledni znanstveni članek

Opis: Purpose: Mobile devices have become an indispensible part of modern communications; they enable easy access to the Internet and also remote manipulation of data stored in corporate information systems. The number of mobile device users is on the rise, but most of them don’t comprehend completely the less obvious functions of these devices. Users also have almost no control over background computer programs, because they run without their knowledge and volition. From the standpoint of information security, a lack of awareness of the risks can seriously compromise the integrity of corporate networks and information systems. The weakest links are users, but also the technology itself. To ensure the functioning and security of information systems, corporations and individual users should learn about protective mechanisms. It is also important that users adhere to implemented (internal) safety regulations. Design/Methods/Approach: We used descriptive and comparative methods, and made an overview of published literature, as well as processes pertaining to the use of mobile devices and related security issues. We compared general elements of information security in regard to the use of mobile devices. Findings: At present mobile devices are more and more frequently used to access information systems. The majority of users are concerned almost exclusively with the question, how to get uninterrupted remote access to data, but far less with security issues. This paper presents some guidelines for achieving and maintaining information security. Research limitations/implications: It has been noted, that this is a time of turbulent development and evolution in the field of mobile devices, and also related security issues, so best practices haven’t been defined yet. Corporations and other organizations have just recently begun defining guidelines to eliminate security breaches through mobile devices, therefore a comparison of their implemented solutions is practically impossible. VS_ Practical implications: We propose guidelines, which can be used to: minimize information security risks posed by mobile devices; evaluate the current state of information security; and implement protective measures against cyber threats encountered by corporations and individual users of mobile devices. Originality/Value: Information security is a relatively new field because mobile devices and remote access to the Internet and data have just recently come into wider use. At the same time security issues and protective measures have stayed largely overlooked. Security threats are many, so it is impervious that users learn more about them and adopt some necessary security measures.

Geo-information technology for disaster risk assessment
Đorđe Ćosić, Sađan Popov, Dušan Sakulski, Ana Pavlović, 2011, izvirni znanstveni članek

Opis: The Serbian territory (including the territory of the former Yugoslavia) has been continuously exposed to different hazards, often with tragic consequences. Earthquakes and floods, usually followed by landslides, are the most dominant hazards in that region. Disaster risk reduction, prevention and early warning, as an integral part of sustainable development, do not exist in Serbia. That is one of the main reasons why the disaster-related damage is high. Despite very long experience in engineering and resources management in Serbia, there are no scientifically supported and standardized disaster risk-assessment procedures. Expertise only exists in the field of engineering-based hazard assessment. The risk-assessment method proposed in this research includes, apart from hazards, parameters such as vulnerability, exposure and safety. It considers the environmental and social components of risk management. The proposed method, implementing combined mathematical and 3D GIS tools, was applied for the Danube River, Petrovaradin (the city of Novi Sad) area, for which data were available. The relationship between the risk parameters is calculated and graphically presented. Methods like this one should contribute to a shift from a passive disaster-related defense to a proactive disaster risk management, as well as from emergency management only, to disaster prevention, preparedness and mitigation activities, in Serbia and the Western Balkan Region.

Teaching information system technology in partnership with IT companies
Viljan Mahnič, 2008, izvirni znanstveni članek

Opis: We describe an example of partnership between a university and some major IT companies - IBM and Microsoft - to teach a course on information systems technology. The course is taught in the fifth (final) year of the university undergraduate program when students have already mastered the basic theoretical knowledge of information system development. For this reason, the course content was restructured to pay more attention to practical experience and the learning opportunities available within the environment of professional industry. During the course, students get acquainted with IBM and Microsoft products and the tools that support the development of online information systems. Special attention is devoted to group project work, which is not just intended for the improvement of technical skills, but also for the aqusition of transferrable skills such as teamwork, management/leadership, planning and organizing, presentation and documentation, searching for information, etc. We describe our experience from teaching the course in the academic years 2005/06 and 2006/07. A description of the course content is given and the results of a survey among the students are presented. Students responded favourably to the new approach and found the course very useful and interesting.

Factors affecting reading speed measurements of coloured web pages
Miro Gradišar, Tomaž Turk, Iztok Humar, 2010, izvirni znanstveni članek

Opis: Most of web-based systems use a fashion-driven graphical user interface design which does not necessarily provide the readers with high reading performance of colour variations of text and background. Many studies addressed this problem but none of them succeeded in offering complete and conclusive results in form of reading performance table which could be used in practice. The aim of this paper is to find reasons for these incomplete results. In our research, we firstly analyzed different experiment designs described in the literature and proposals for further research. Consequently, we tried to find an improved design and carried out an experiment involving 270 students who tested 30 web-safe colour combinations. However, our experiment also did not reveal statistically significant differences in reading speed. Therefore the multidimensional scaling (MDS) method was performed to show that the speed of reading cannot be described as a one-dimensional problem.

A review of critical success factors for offshore software development projects
Goparaju Purna Sudhakar, 2013, izvirni znanstveni članek

Opis: Offshore project success is very much important to both customer and the vendor. Based on very less success rate of overall software projects globally, critical success factors (CSFs) for offshore software projects is gaining much importance. In the current study based on literature review, a total of 75 success factors for offshore software projects are identified. Further based on their appearance in literature 20 critical success factors from 10 CSF categories are identified. Finally top six most critical success factors for offshore software projects such as trust, efficient communication, cultural understanding, relationship between client and vendor, contract type and efficient knowledge transfer are identified. The CSFs categories are prioritized in the order of importance. The important CSF categories for offshore projects found are organizational factors (both client and vendor), project factors, cultural factors and environmental factors.

Information sharing promotes prosocial behaviour
Attila Szolnoki, Matjaž Perc, 2013, izvirni znanstveni članek

Opis: More often than not, bad decisions are bad regardless of where and when they are made. Information sharing might thus be utilized to mitigate them. Here we show that sharing information about strategy choice between players residing on two different networks reinforces the evolution of cooperation. In evolutionary games, the strategy reflects the action of each individual that warrants the highest utility in a competitive setting. We therefore assume that identical strategies on the two networks reinforce themselves by lessening their propensity to change. Besides network reciprocity working in favour of cooperation on each individual network, we observe the spontaneous emergence of correlated behaviour between the two networks, which further deters defection. If information is shared not just between individuals but also between groups, the positive effect is even stronger, and this despite the fact that information sharing is implemented without any assumptions with regard to content.

Logistic operator - fundamental factor in rational production of services in multimodal transport
Ratko Zelenika, Drago Sever, Sabina Kamnik Zebec, Bojan Pirš, 2005, pregledni znanstveni članek

Opis: From its theoretical and practical point of view, traffic is one of the fundamental factors of the economy in a state. In the developed European countries, a rational production of transport services is presented by multimodal transport and the correct selection of a logistic operator. The aim of multimodal transport is to link together different forms of traffic in the most effective way, as well as all operations considering transport. The logistic operator is the only professional to perform complete services in multimodal transport, therefore it was necesarry to enable its further development and, in accordance with that, to suggest suitable solutions. An increase of the existing and the creation of new traffic currents can only be achieved with the development of multimodal transport, the correct selection of logistic operator and better organisation of the traffic system. In the future, the Republic of Slovenia should continue developing multimodal transport in order to decrease the differences in forms of transport in the developed European countries in the shortest time possible.The main task of the Republic of Slovenia is to integrate into the European flows as soon as possible, engage in a reciprocal cooperation by liberalization of flows of commodities and services, and create conditions for the inflow of foreign capital where all advantages of multimodal transport come into consideration. The result of the research is a model of multimodal transport logistic operator connecting the basic elements of that transport.
