Analysis of the spanish electricity market and proposals for future development
Ester Getino, Emilio García, Klemen Deželak, published scientific conference contribution

Abstract: Nowadays the electricity is found in any daily activity, while a state can not develop its economic and social potential without a consolidated electricity system. In sense of the liberalized electrical systems, the figure of an electric market becomes fundamental. This paper shows an overview of the Spanish electricity market, involving its problems and future objectives. Spain as a member of the European Union faces the demands proposed by the European Commission. The European challenge is not an individual challenge for individual member but requires the cooperation of all member states, moving towards an energetically integrated European Union.
Keywords: electricity market, liberalization, Spain, generation, transportation, distribution

Koncept prostorske analize rabe in proizvodnje toplote v Mestni občini Maribor
Jure Čižman, Damir Staničić, Matjaž Česen, Miran Rožman, Ljubo Germič, Filip Kokalj, published scientific conference contribution

Abstract: Trajnostne rešitve za ogrevanje in hlajenje temeljijo na sodobnih tehnologijah in vedno večjem povezovanju različnih sektorjev rabe in proizvodnje energije – stavb, industrije, proizvodnje električne energije ter prometa. Sistemi daljinskega ogrevanja in hlajenja omogočajo povezovanje različnih sektorjev in s tem zagotavljajo učinkovito upravljanje z vsemi razpoložljivimi viri in ponori energije. Takšen pristop zahteva sistemsko črtovanje ravnanja z energijo v lokalni skupnosti, ki temelji na podrobni prostorski analizi obstoječega stanja in prihodnjega razvoja. V prispevku je predstavljen koncept prostorske analize rabe in oskrbe s toploto z uporabo orodij geografskega informacijskega sistema v Mestni občini Maribor(MOM).
Keywords: trajnostne rešitve, ogrevanje, hlajenje, prostorska analiza, geografski informacijski sistem

Trend analysis of journal metrics: a new academic library service?
Peter Kokol, 2017, original scientific article

Abstract: Objective: Temporal trends in source normalized impact per paper (SNIP) values for the three top-ranking nursing journals were analyzed and compared to explore whether predicting future SNIP values based on trend analysis could be an innovative service provided by librarians. Methods: The International Journal of Nursing Studies, Journal of Nursing Scholarship, and Journal of Advanced Nursing were the three top-ranked nursing journals according to 2015 SNIP values. SNIP values for the selected journals were retrieved from the Scopus database, and extracted data were exported to Joinpoint trend analysis software to perform trend analysis. Results: The trend in SNIP values for the International Journal of Nursing Studies was the most stable and positive, whereas the trend in SNIP values for the Journal of Advanced Nursing was the most negative. The annual percentage change of the most recent trend line, which is the best indicator for predicting future SNIP values, was the largest for the International Journal of Nursing Studies. Conclusions: Predictions of journal metrics based on statistical joinpoint regression may not be completely accurate. Using this technique, however, a librarian can reasonably claim which journal will retain or even improve its prestige in the future and thus safely advise prospective authors on where to publish their research.
Keywords: publish or perish, medical library, trend analysis, journal impact factor, joinpoint regression

Simulating various terrestrial and UAV LiDAR scanning configurations for understory forest structure modelling
Marina Hämmerle, Niko Lukač, K.-C. Chen, Zsófia Koma, C.-K. Wang, K. Anders, B. Höfle, 2017, published scientific conference contribution

Abstract: Information about the 3D structure of understory vegetation is of high relevance in forestry research and management (e.g., for complete biomass estimations). However, it has been hardly investigated systematically with state-of-the-art methods such as static terrestrial laser scanning (TLS) or laser scanning from unmanned aerial vehicle platforms (ULS). A prominent challenge for scanning forests is posed by occlusion, calling for proper TLS scan position or ULS flight line configurations in order to achieve an accurate representation of understory vegetation. The aim of our study is to examine the effect of TLS or ULS scanning strategies on (1) the height of individual understory trees and (2) understory canopy height raster models. We simulate full-waveform TLS and ULS point clouds of a virtual forest plot captured from various combinations of max. 12 TLS scan positions or 3 ULS flight lines. The accuracy of the respective datasets is evaluated with reference values given by the virtually scanned 3D triangle mesh tree models. TLS tree height underestimations range up to 1.84 m (15.30 % of tree height) for single TLS scan positions, but combining three scan positions reduces the underestimation to maximum 0.31 m (2.41 %). Combining ULS flight lines also results in improved tree height representation, with a maximum underestimation of 0.24 m (2.15 %). The presented simulation approach offers a complementary source of information for efficient planning of field campaigns aiming at understory vegetation modelling.
Keywords: forest structure, understory, laser scanning simulation, full waveform, 3D point cloud analysis, field campaign planning

Inference attacks and control on database structures
Muhamed Turkanović, Tatjana Welzer-Družovec, Marko Hölbl, 2015, original scientific article

Abstract: Today’s databases store information with sensitivity levels that range from public to highly sensitive, hence ensuring confidentiality can be highly important, but also requires costly control. This paper focuses on the inference problem on different database structures. It presents possible treats on privacy with relation to the inference, and control methods for mitigating these treats. The paper shows that using only access control, without any inference control is inadequate, since these models are unable to protect against indirect data access. Furthermore, it covers new inference problems which rise from the dimensions of new technologies like XML, semantics, etc.
Keywords: inference, attacks, database, security, semantics

Sleeping beauties in pediatrics
Jernej Završnik, Peter Kokol, 2016, short scientific article

Abstract: Sleeping beauties (SBs) in science have been known for few decades; however, it seems that only recently have they become popular. An SB is a publication that ‘‘sleeps’’ for a long time and then almost suddenly awakes and becomes highly cited. SBs present interesting findings in science. Pediatrics research literature has not yet been analyzed for their presence, and 5 pediatrics SBs were discovered in this research. Their prevalence was approximately 0.011%. Some environments or periods are more ‘‘SB fertile’’ than others: 3 of 5 SBs were published in the journal Pediatrics, 4 originated from the United States, and 4 were published in the period from 1992 to 1993. No institutions or authors published more than 1 SB.

Prikriveno oglašivanje kao primjer neetičnog djelovanja medija
Tina Tomažič, Jelena Jurišić, Damir Boras, 2011, original scientific article

Abstract: Oglašivanje je jedan od ključnih faktora za stimuliranje procesa razmjene te za normalno djelovanje tržišta i njegovih zakona. Oglašivači imaju na raspolaganju puno načina i mogućnosti kojima pokušavaju privući pažnju potencijalnih potrošača. Zbog sve veće konkurencije na tržištu često posežu za novim načinima oglašivanja koji nisu uvijek u skladu sa zakonom i etičnim djelovanjem. Jedan od tih načina jest i prikriveno oglašivanje. U ovom radu analiziramo prikriveno oglašivanje kao primjer neetičnog djelovanja medija jer prikrivene oglasne poruke predstavljaju jedan od najočiglednijih problema na medijskom tržištu. Uz pomoć spoznaja iz literature definiramo pojam prikrivenog oglašivanja. Cilj je našeg rada i povezivanje društvenih okolnosti koje su uzrok prikrivenog oglašivanja s promjenama medijskih diskurzivnih praksi.

Media literacy in times of media divides
Kaja Žuran, Marko Ivanišin, 2013, original scientific article

Abstract: We live in a post-modern society, an information society, a society based around knowledge and participation, and above all in a media society. In a media culture where media holds a dominant position, we cannot overlook the emerging idea of a ‘media divide’ within the frame of media education, media literate individuals and the expansion of the traditional concept of media literacy. Firstly, we are in an era of technological revolution, and it is time to consider the meaning and function of media and how we experience it in our everyday life. Secondly, as a society we are subject to intense media invasion and we all need to learn how to use it to our benefit and apply a critical and autonomous perspective towards selecting media content. Otherwise the media divide between the media literate and illiterate will widen; but is there even a chance to overcome the supposed divide between those who are formally media educated and those who are not?
