Unlimited access to information systems with mobile devices
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.

The Impact of the EU General Data Protection Regulation (GDPR) on mobile devices
Domen Hribar, Miha Dvojmoč, Blaž Markelj, 2018, izvirni znanstveni članek

Opis: Purpose: The purpose of this paper is to examine novelties introduced by the European Regulation (2016/679) on the Protection of Natural Persons with Regard to the Processing of Personal Data (GDPR) and its key impacts on mobile device users. The paper also presents some of the main changes affecting both natural persons and legal entities. Further, certain issues that might occur while implementing the Regulation are raised together with the degree of individuals’ awareness of the need to protect the personal data stored on their mobile devices. Design/Methods/Approach: For the purpose of this paper, we reviewed the legislation, Slovenian and international literature, brochures and media stories in the field of personal data protection. We also used a questionnaire to determine the degree of awareness of the importance of protecting personal data among the general population. Findings: The findings show that no revolutionary changes are introduced. Nevertheless, quite a few novelties concern data controllers and processors. In particular, penalties for breaching the GDPR are now much higher. Individuals’ rights are strengthened and easier to control. In contrast, data controllers and processors are subject to more stringent duties and legal obligations. These changes also apply to mobile device users. The research findings show that individuals are relatively well aware of the concept of personal data; however, the scope of their knowledge shrinks as this concept becomes increasingly complex. Familiarity with the new Regulation (2016/679) having been introduced at the EU level was claimed by 55% of the respondents (N = 195). Research Limitations / Implications: The limitations stem from the selective choice of the GDPR’s impact on mobile device users. More important influences are emphasised. Originality/Value: The findings will help both individuals and legal entities understand the changes brought to the area of data protection and tackle them more successfully.

Efficacy of a bundle approach in preventing the incidence of ventilator associated pneumonia (VAP)
Sandra Burja, Tina Belec, Nika Bizjak, Jernej Mori, Andrej Markota, Andreja Sinkovič, 2017, izvirni znanstveni članek

Opis: Ventilator-associated pneumonia (VAP) is a potentially preventable iatrogenic illness that may develop following mechanical ventilation. A bundle for the prevention of VAP consists of different measures which may vary between institutions, and may include: elevation of the head of the bed, oral care with chlorhexidine, subglottic suctioning, daily assessment for extubation and the need for proton-pump inhibitors, use of closed suction systems, and maintaining endotracheal cuff pressure at 25 cmH2O. Our aim was to determine the efficacy of a VAP prevention bundle, consisting of the above-mentioned measures, by evaluating the incidence of VAP before (no-VAP-B group) and after (VAP-B group) the introduction of the bundle. We retrospectively evaluated the data for patients who were mechanically ventilated with an endotracheal tube, in the period between 1 September and 31 December 2014 (no-VAP-B group, n = 55, 54.5% males, mean age 67.8 ± 14.5 years) and between 1 January to 30 April 2015 (VAP-B group, n = 74, 62.1% males, mean age 64.8 ± 13.7 years). There were no statistically significant differences between no-VAP-B and VAP-B groups in demographic data, intensive care unit (ICU) mortality, hospital mortality, duration of ICU treatment, and duration of mechanical ventilation. No significant differences in the rates of VAP and early VAP (onset ≤7 days after intubation) were found between no-VAP-B and VAP-B groups (41.8% versus 25.7%, p = 0.06 and 10.9% versus 12.2%, p > 0.99, respectively). However, a significant decrease in the late VAP (onset >8 days after intubation) was found in VAP-B group compared to no-VAP-B group (13.5% versus 30.9%, p = 0.027). Overall, our results support the use of VAP prevention bundle in clinical practice.

The Importance of the First Impression and the use of Gestalt Principles of Visaul Design while visiting Web Sites on Mobile Phone
Aleš Studen, 2017, diplomsko delo

Opis: This paper introduces an overview of the first impression on web regarding visual design in connection with user’s opinion. The definition of the first impression is explained as well as its importance. Visual design plays an important role whether website creates good or bad first impression. Gestalt principles of visual design are presented with given website examples. To confirm connection between the first impression and gestalt principles of design, eye-tracking study was performed. Successfully completed analysis was completed with 15 participants. Visual appearance plays an important role in evaluation but it is not the only factor. It is confirmed that out of four websites, the one using the more gestalt principles was at the final individual evaluation assessed the best. It is proven that also the manner of the information provided plays a significant role.

Cooling analysis of a light emitting diode automotive fog lamp
Matej Zadravec, Matjaž Ramšak, Jure Ravnik, Matjaž Hriberšek, Jernej Slanovec, 2017, izvirni znanstveni članek

Opis: Efficiency of cooling fins inside of a light emitting diode fog lamp is studied using computational fluid dynamics. Diffusion in heat sink, natural convection and radiation are the main principles of the simulated heat transfer. The Navier-Stokes equations were solved by the computational fluid dynamics code, including Monte Carlo radiation model and no additional turbulence model was needed. The numerical simulation is tested using the existing lamp geometry and temperature measurements. The agreement is excellent inside of few degrees at all measured points. The main objective of the article is to determine the cooling effect of various heat sink parts. Based on performed simulations, some heat sink parts are found to be very ineffective. The geometry and heat sink modifications are proposed. While radiation influence is significant, compressible effects are found to be minor.

Mobile devices and effective information security
Blaž Markelj, Igor Bernik, 2013, izvirni znanstveni članek

Opis: Rapidly increasing numbers of sophisticated mobile devices (smart phones, tab computers, etc.) all over the world mean that ensuring information security will only become a more pronounced problem for individuals and organizations. It’s important to effectively protect data stored on or accessed by mobile devices, and also during transmission of data between devices and between device and information system. Technological and other trends show, that the cyber threats are also rapidly developing and spreading. It's crucial to educate users about safe usage and to increase their awareness of security issues. Ideally, users should keep-up with technological trends and be well equipped with knowledge otherwise mobile technology will significantly increase security risks. Most important is that we start educating youth so that our next generations of employees will be part of a culture of data and information security awareness.

Criminal responsibility of students regarding using mobile devices and violating the principles of information security
Blaž Markelj, Sabina Zgaga, 2014, izvirni znanstveni članek

Opis: The combination of information security and criminal law in the case of usage of smart mobile phones among the students is a very relevant and current topic. Namely, the number of smart mobile phones’ users is rising daily, including among the student population, due to the need for perpetual communication and constant access to information. However, the lack of knowledge about recommendations on information security and safe use of smart mobile phone together with their disregard could lead to criminal responsibility of the users of smart mobile phones, including students. The purpose of this paper is therefore to represent the potential consequences of criminal responsibility and how to avoid it. The knowledge on safe use of smart mobile phones, their software, but also threats and safety solutions is very low among students, as the survey shows. Due to the loss, conveyance or disclosure of protected data, criminal responsibility of a user could therefore be relevant. In certain cases the juvenile criminal justice system is partly still relevant due to the students’ age, whereas in every case the students' culpability should be assessed precisely. This assessment namely distinguishes the cases, when the student is a perpetrator of a criminal act from the cases, when the student is only a victim of a criminal act due to his improper use of smart mobile phones.

An innovative approach to near-infrared spectroscopy using a standard mobile device and its clinical application in the real-time visualization of peripheral veins
Simon Jurič, Borut Žalik, 2014, izvirni znanstveni članek

Opis: Background: Excessive venipunctures are a significant problem both in emergency rooms and during hospital stays. Near-infrared (NIR) illumination devices improve venipuncture success rate but their usage is limited by their availability and economic cost. The objectives of this study were to develop a low-cost NIR spectroscopy prototype from a standard mobile device, to evaluate its efficacy and acceptance as an educational tool, and in a clinical setting. Methods: Through a user-centric design process a prototype device was developed. Its educational efficacy was evaluated through a non-invasive, observational study (20 student clinicians, 25 subjects) and its acceptance was assessed using quantitative and qualitative analysis. A smaller clinical trial was performed by a group of 4 medical professionals over a period of 6 weeks that involved 64 patients. Results: The prototype enables real-time visualization of peripheral veins on a variety of Android-based devices. The prototype was 35.2% more successful in visualizing and locating veins (n = 500 attempts) than the nursing students. The acceptance assessment revealed high perception of usefulness, satisfaction, and ease of use. In the clinical trial, 1.6 (SD 1.3) additional veins per patient were identified compared with the traditional visualization methods. Conclusions: To the best of our knowledge this is the first study that describes the design, feasibility and application of an NIR spectroscopy prototype developed on a standard mobile device.

Towards a low-cost mobile subcutaneous vein detection solution using near-infrared spectroscopy
Simon Jurič, Vojko Flis, Matjaž Debevc, Andreas Holzinger, Borut Žalik, 2014, pregledni znanstveni članek

Opis: Excessive venipunctures are both time- and resource-consuming events, which cause anxiety, pain, and distress in patients, or can lead to severe harmful injuries. We propose a low-cost mobile health solution for subcutaneous vein detection using near-infrared spectroscopy, along with an assessment of the current state of the art in this field. The first objective of this study was to get a deeper overview of the research topic, through the initial team discussions and a detailed literature review (using both academic and grey literature). The second objective, that is, identifying the commercial systems employing near-infrared spectroscopy, was conducted using the PubMed database. The goal of the third objective was to identify and evaluate (using the IEEE Xplore database) the research efforts in the field of low-cost near-infrared imaging in general, as a basis for the conceptual model of the upcoming prototype. Although the reviewed commercial devices have demonstrated usefulness and value for peripheral veins visualization, other evaluated clinical outcomes are less conclusive. Previous studies regarding low-cost near-infrared systems demonstrated the general feasibility of developing cost-effective vein detection systems; however, their limitations are restricting their applicability to clinical practice. Finally, based on the current findings, we outline the future research direction.

Contrasts in metaphysical writing
Tadej Braček, 2010, izvirni znanstveni članek

Opis: This paper starts by stating what metaphysical poetry is, what its characteristics are, and who the metaphysical poets are. Later the paper focuses on Emily Dickinson's poetry and confirms the thesis that she can be considered a metaphysical poet. The third thing the paper deals with is to what extent Donne's and Dickinson's poetry as well as Donne's Sermons correspond to the Calvinist theology, which is the common credo of the Churches to which they belong. A further issue the paper debates about is rhetorical devices in the metaphysical service. The last aspect of Donne's and Dickinson's writing that the essay explores is their attitude towards truth.
