Experiencing stress among nurses during resuscitation procedure and legal obligations for healthcare workers in Slovenia
Anton Koželj, Maja Strauss, Matej Strnad, 2020, izvirni znanstveni članek

Opis: Nurses are always part of the team that performs resuscitation procedures. In this paper the authors explore the influence that resuscitation procedures on nurses who perform them. For data collection, the authors used a survey with a convenience sample of nurses who work in emergency settings. For statistical processing of data, the authors used the calculation of frequency, standard deviation, means, and median. Authors used Spearman's rank correlation coefficient and calculated the p-value. The respondents in the survey completed the Post-Code Stress Scale. The results show that the majority of the respondents experienced resuscitation cases as burdensome situations; however, the level of stress was moderate. Nurses still experience some physical and psychological symptoms during resuscitations.

How to strengthen employee engagement among Slovenian criminal investigators?
David Smolej, 2017, izvirni znanstveni članek

Opis: Purpose: In terms of providing security, employee engagement may be defined as an important contribution by individual criminal investigators or their physical, cognitive and emotional dedication to their work. Employee engagement positively correlates with one’s work, as reflected in the dedication, absorption, and psychological state accompanied by personal energy invested in the work. A fundamental question for the criminal investigation police thus arises of how to achieve maximum engagement and commitment in police work, which in turn will contribute to greater security in Slovenia. Design/Methods/Approach: The article is based on empirical research conducted among 160 Slovenian criminal investigators. We used Gallup’s Q12 Employee Engagement Survey to measure employee engagement. Findings: The research encompassing 160 Slovenian criminal investigators shows that most criminal investigators are disengaged. The research also reveals that employee engagement is statistically significantly correlated with self-efficacy, social undermining by one’s supervisor, social support by one’s supervisor and colleagues, as well as cynicism. To raise employee engagement among the Slovenian criminal investigators, we propose several measures affecting the conduct of the police, labour legal matters, operational issues and the leadership. Research Limitations / Implications: The first limitation is social desirability bias. The second limitation is a labour strike that was underway while we were collecting the data from the police officers. Practical Implications: The proposed actions should raise the level of employee engagement of Slovenian criminal investigators, while also enhancing the police service’s reliability. Originality/Value: This is the first paper to research employee engagement among Slovenian criminal investigators.

A three-dimensional static numerical model of a complex underground structure in high squeezing ground
Tina Marolt Čebašek, Jakob Likar, 2015, izvirni znanstveni članek

Opis: The present study assesses high squeezing ground confirmed by empirical and semi-empirical theories. High squeezing ground is often present in underground constructions at great depths, but it is hardly ever researched separately from light and fair squeezing ground. A three-dimensional, static numerical model is developed for a complex underground structure consisting of a shaft, a silo, and a mine roadway at great depth, which is certainly in high squeezing ground. Furthermore, a solution for the entire structure based on shotcrete with incorporated yielding elements is provided. The yielding elements, in general, absorb the strain energy by compressing at a relatively constant stress, but without rebounding. A three-dimensional, static numerical model of a support system with incorporated yielding elements is established in order to demonstrate that the presented forces are under control. Therefore, a failure of the lining is avoided because the stresses in the shotcrete lining are below its load-bearing capacity. It can be concluded that yielding elements incorporated in the shotcrete lining play an important role in the support solution in high squeezing ground.

Landslide assessment of the Strača basin (Croatia) using machine learning algorithms
Miloš Marjanović, Miloš Kovačević, Branislav Bajat, Snježana Mihalić Arbanas, Biljana Abolmasov, 2011, izvirni znanstveni članek

Opis: In this research, machine learning algorithms were compared in a landslide-susceptibility assessment. Given the input set of GIS layers for the Starča Basin, which included geological, hydrogeological, morphometric, and environmental data, a classification task was performed to classify the grid cells to: (i) landslide and non-landslide cases, (ii) different landslide types (dormant and abandoned, stabilized and suspended, reactivated). After finding the optimal parameters, C4.5 decision trees and Support Vector Machines were compared using kappa statistics. The obtained results showed that classifiers were able to distinguish between the different landslide types better than between the landslide and non-landslide instances. In addition, the Support Vector Machines classifier performed slightly better than the C4.5 in all the experiments. Promising results were achieved when classifying the grid cells into different landslide types using 20% of all the available landslide data for the model creation, reaching kappa values of about 0.65 for both algorithms.

Back analysis of time-dependet displacement at the Trojane tunnel construction
Jakob Likar, 2004, izvirni znanstveni članek

Opis: The 2,900-metre double tube tunnel of Trojane forms part of the highway section between Celje and Ljubljana and part of the highway road system connecting Lendava and Koper with adjacent roads. The construction of this section, which is of special importance for the Republic Slovenia, has been going on for almost ten years. The highway near Trojane where the tunnel is located, lies on a hilly terrain composed of Permian-carboniferous rocks, which are tectonically badly damaged in some places and marked with broad fault zones, containing tectonically remoulded soil of low strength in terms of deformability properties. Even though the amount of waters coming from the hills during the excavation of the tunnel was relatively small, this water, in combination with extremely damaged weak rock caused the increase of deformations at the construction site. Geological and geotechnical surveying with geometric monitoring and the analyses of stress and deformation changes in the surrounding rocks and support elements were critical in assessing the actual weak-rock conditions during the course of construction. Since the analyses of deformation processes, which had been modelled with PLAXIS 3D TUNNEL PROGRAM, showed great impact on permanent stability of the tunnel, special care was paid to rheological changes in the surrounding rocks and combined in-built support elements. 3D back analyses with SOFT-SOIL-CREEP (SSC) constitutive model, which takes into account rheological phenomena, were carried out. The calculations of primary and secondary stresses and deformations were made for two characteristic areas and determined on the basis of realistic geological mapping during tunnel construction. The first area represented typical rocks of the Trojane tunnel, i.e. shales and siltstone, while the second one was a tectonic zone where geological and geotechnical conditions during excavation were less favourable. The results of back analyses used provided an acceptable possibility for estimating the stress-strain variation during construction as well as an appropriate basis for analysing vertical displacements at the tunnel roof. The calculation results show good correlation with field measurements.

Public support of solar electricity and its impact on households - prosumers
Jarmila Zimmermannová, Adam Pawliczek, Petr Čermák, 2018, izvirni znanstveni članek

Opis: Background and Purpose: Currently, the idea of households - prosumers is broadly discussed in public governments, mainly in connection with both the energy security issues and the environmental issues. Therefore, the main goal of this paper is to present new agent model of household - prosumer and to compare two scenarios – “off grid household” and “on grid household”. The additional goal is to evaluate the impact of public support of solar electricity on the economic efficiency of household – prosumer projects (systems). Design/Methodology/Approach: The model is structured as a micro-level agent model, representing one household – prosumer. The model has the following general characteristics: one household with own electricity generation (photovoltaic panels), battery and in case of “on grid household” also connection to the grid. The main goal of the agent is to cover electricity consumption in household with minimal costs. The agent model of prosumer is tested and validated, using the empirical data. Results: The highest level of subsidy has significant impact on the economic indicators of selected scenarios. It causes lower investment costs at the beginning of the project and consequently shorter payback period (3-4 years earlier), positive cumulative cash flow, net present value and IRR in earlier period (approximately 5-10 years earlier, depending on the scenario). Conclusion: We can recommend to the government to continue with current system of subsidies, since it contributes to better economic indicators of particular solar electricity projects. On the other hand, the level of subsidy should be at least the same as in current year 2017, for the purposes of representing the significant part of the investment costs. Low level of subsidy has negligible impact on the economic indicators of households – prosumers projects. The developed agent model is suitable for the evaluation of economic impact of public support on households – prosumers.

Tatjana Kovač, 2015, izvirni znanstveni članek

Opis: Background and Purpose: The objective of this research was to develop a proposal of the evaluation information support in higher education that encompasses the Quality Assessor’s and Quality Analyst’s work support. Furthermore, the proposal also includes the fields evaluated in the processes of external evaluation of the higher education institutes by the Slovenian National Agency for Quality Assurance in Higher Education (hereinafter referred to as »NAKVIS«). Methodology: The method called the “Multi-Attribute Utility Theory” (hereinafter referred to as “MAUT”) and MS Excel were used for the work support of the Quality Assessors, while the expert modelling in the Decision Expert programme (hereinafter referred to as “Dexi programme”) was used for the work support of the Quality Analysts. Results: The identified criteria allow a uniform evaluation, regardless of the Assessor. The MS Excel template with automatic calculation was made as the technical support for an evaluator and the expert model in Dexi programme was designed for a Quality Analyst. Conclusion: The model of the Higher Education Institute quality evaluation, as presented in this article, can provide a comprehensive and transparent consideration of quality at the Faculty, and, in particular, facilitate the evaluation process due to its information and technical support.

Financial distress prediction of Iranian companies using data minig techniques
Mahdi Moradi, Mahdi Salehi, Mohammad Ebrahim Ghorgani, Hadi Sadoghi Yazdi, 2013, izvirni znanstveni članek

Opis: Decision-making problems in the area of financial status evaluation are considered very important. Making incorrect decisions in firms is very likely to cause financial crises and distress. Predicting financial distress of factories and manufacturing companies is the desire of managers and investors, auditors, financial analysts, governmental officials, employees. Therefore, the current study aims to predict financial distress of Iranian Companies. The current study applies support vector data description (SVDD) to the financial distress prediction problem in an attempt to suggest a new model with better explanatory power and stability. To serve this purpose, we use a grid-search technique using 3-fold cross-validation to find out the optimal parameter values of kernel function of SVDD. To evaluate the prediction accuracy of SVDD, we compare its performance with fuzzy c-means (FCM).The experiment results show that SVDD outperforms the other method in years before financial distress occurrence. The data used in this research were obtained from Iran Stock Market and Accounting Research Database. According to the data between 2000 and 2009, 70 pairs of companies listed in Tehran Stock Exchange are selected as initial data set.
