1. Combined effect of build orientation and energy density on density and mechanical properties of selectively laser melted Co-Cr-W-SiSnehashis Pal, Igor Drstvenšek, 2022, izvirni znanstveni članek Opis: The selective laser melting (SLM) process for manufacturing metals continues to be
challenging in terms of achieving the maximum metallurgical properties that the process can
provide. There are a variety of manufacturing parameters in the process that have individual
characteristics, and when combined with other variables, the characteristics can be varied.
However, in this study, the two most important manufacturing parameters, namely build direction
and laser power, were considered to investigate their effects on density and tensile properties.
Previously, the best scanning speed, hatch spacing, and layer thickness were determined, which
directly affect the volumetric energy density in the SLM process. In this study, three different
orientations and three different laser powers were selected, namely the X, Y, and Z directions and
55 W, 75 W, and 95 W laser power, respectively. Significant differences in product density were
observed for the samples fabricated in the different orientations and with the different laser
powers. The specimens fabricated in the Z direction always exhibit higher strength and ductility,
which are significantly different from the specimens fabricated in the X and Y directions, while
the laser power was 75 W and 95 W, respectively

2. Political orientation in youth beyond the left-right divide : testing a three-factor model of political orientation and its relatedness to personal valuesŽan Lep, Andrej Kirbiš, 2021, izvirni znanstveni članek Opis: The utility of the left-right dimension of political orientation, including among youth, has been questioned recently. Moreover, a sizeable share of young voters in Slovenia has a hard time describing their political orientation. In present research we thus explored whether a multi-dimensional model of social, economic and international dimension, could be better suited for describing young people's political orientations. In addition, as values precede political stances, we explored the relatedness of personal values with proposed dimensions of political orientation and whether the predictive power of regression models containing control background variables could be improved by their inclusion. We used FES Youth Study Southeast Europe 2018/19 data of 1,015 14-29-year-old Slovenians. The three dimensions exhibited good fit to the data and were relatively independent of the left-right placements, offering valuable additional insight into political thinking of youth. Moreover, the values were predictive of scores on all three dimensions over and beyond the included control variables, and shares of explained variances were higher than those with the left-right dimension. While the study has some limitations, findings suggest that a multi-dimensional approach to political orientation could be beneficial in research dealing with the aspects of the ever-changing political and social landscape.

3. Core values of family medicine in Europe : current state and challengesEva Arvidsson, Igor Švab, Zalika Klemenc-Ketiš, 2021, izvirni znanstveni članek Opis: Background: Values are deeply held views that act as guiding beliefs for individuals and organizations. They state what is important in a profession. The aims of this study were to determine whether European countries have already developed (or are developing) documents on core values in family medicine; to gather the lists of core values already developed in countries; and to gather the opinions of participants on what the core family values in their countries are.
Methods: This was a qualitative study. The questionnaire was distributed as an e-survey via email to present and former members of the European Society for Quality and Safety in Family Practice (EQuiP), and other family medicine experts in Europe. The questionnaire included six items concerning core values in family medicine in the respondent's country: the process of defining core values, present core values, the respondents' suggestions for core values, and current challenges of core values.
Results: Core values in family medicine were defined or in a process of being defined in several European countries. The most common core values already defined were the doctor-patient relationship, continuity, comprehensiveness and holistic care, community orientation, and professionalism. Some countries expressed the need for an update of the current core values' list. Most respondents felt the core values of their discipline were challenged in today's world. The main values challenged were continuity, patient-centered care/the doctor-patient relationship and comprehensive and holistic care, but also prioritization, equity, and community orientation and cooperation. These were challenged by digital health, workload/lack of family physicians, fragmentation of care, interdisciplinary care, and societal trends and commercial interests.
Conclusion: We managed to identify suggestions for core values of family medicine at the European level. There is a clear need to adopt a definition of a value and tailor the discussion and actions on the family medicine core values accordingly. There is also a need to identify the core values of family medicine in European countries. This could strengthen the profession, promote its development and research, improve education, and help European countries to advocate for the profession.

4. A z-axis-tolerant inductive power transfer system using a bipolar double d receiver coil structureJure Domajnko, Nataša Prosen, 2023, izvirni znanstveni članek Opis: This paper presents a solution to a limitation of wireless power transfer that arises when using two D-shaped transmitter and receiver coils. Double D, or DD, coils are well known to have a polar, directional magnetic field, which increases the misalignment tolerance in one of the directions. The misalignment tolerance is nonsymmetric, and it is significantly better in one of the directions, which can also be considered a shortcoming. An additional shortcoming of the DD coil is that it is dependent on the rotation around the z-axis, due to the directional magnetic field. This is not a problem when using classic planar spiral coils, which do not generate a directional magnetic field. Therefore, DD coils are not suitable for applications in which the z-axis orientation is not determined and fixed to specific angle and direction. This paper presents a unique design of a transmitter coil, based on a double DD coil. The transmitter coil consists of two DD coils which are perpendicular to each other. The proposed transmitter structure can excite the receiver DD coil in a way that the efficiency of the power transfer is the highest, regardless of the orientation. The proposed transmitter structure can, therefore, solve the problem with rotation of a single DD coil. The proposed system structure was tested on the small-scale experimental setup

5. The role of B2B marketing strategy, ICT B2B marketing support, and service quality in market orientation – Performance relationship : evidence from three European countriesGregor Jagodič, Borut Milfelner, 2022, izvirni znanstveni članek Opis: The purpose of this study is to evaluate the role of marketing strategy, information communication technology (ICT) marketing support, and service quality in the market orientation–performance relationship. Even though there are many studies considering the market orientation–performance relationship they rarely take into consideration ICT marketing support and marketing strategy, especially concerning the companies operating in B2B markets. Additionally, this study compares the impacts of the constructs between two emerging economies (Slovenia and Serbia) and one developed economy (Austria) on a random sample of 636 companies. Results were obtained based on the set hypotheses using the covariance-based structural equation modeling (SEM) and invariance testing procedure to make comparisons between the three countries. Market orientation strongly influenced the successful development and implementation of marketing strategies, ICT support, and service quality. The impact of service quality on company performance was statistically insignificant and only the indirect impact of market orientation on company performance through service quality was determined. ICT marketing support and successful development and implementation of B2B marketing strategy were also positively related to company performance. This study can help managers in B2B companies in emerging and developed markets to learn how to use specific marketing resources in order to achieve higher company performance.

7. The direct and indirect relationships between design orientation and market orientationSanja Rocco, 2019, doktorska disertacija Opis: The main purpose of this doctoral thesis is to investigate the relationship between design orientation and market orientation and propose a new conceptual model. Existing models were investigated. The initial conceptual model was proposed as the starting point. The research combined qualitative and quantitative methods. Quantitative research was conducted among managers and CEOs from Croatian companies in different industries. According to the final PLS-SEM model, design orientation has a direct and significant impact on market orientation and an indirect but significant impact on business success. Managerial approach has a direct and significant impact on design orientation, as well as on market orientation of a company. The new design orientation-market orientation model contributes to both marketing and design scholars, as well as implications for marketers, designers, and managers in practice. Our findings demonstrate that companies with higher level of market orientation and supported with design orientation also have the potential for achieving better results in the market and, consequently, better financial performance. It also provides the basis for future research on the topic.

8. Organisational effectiveness and customer satisfactionMilan Ambrož, Martina Praprotnik, 2008, izvirni znanstveni članek Opis: This paper presents a test of the relationship between organizational culture as a crucial indicator of organizational effectiveness and customer satisfaction using service-unit data from two health resorts. Ensuring survival of the service organisation in the long run requires adaptations which are oriented towards achieving maximum customer satisfaction. This study intended to unveil the effect organisational factors have on customer service orientation from the customer and employee point of view within a two health resort service setting. The finding suggests that when trying to predict the comparative degree which organisational effectiveness factors have in satisfying customers' needs, performance, adaptability and mission can be of the highest importance. Some effects like performance were uniform for employees and customers, while others varied depending on the organisation and the customer or employee group. Furthermore, findings suggest that service performance and organisation mission of the service organisation predict customer satisfaction based on established and proven health services. In this context there is no room for innovation, despite the fact that employees and customers do not share similar views about the impact of organisational effectiveness. Developing an effective service organisation can provide a competitive advantage to the organisation. Critical for the success of the service organisation is that organisational agents have a clear view of the existing organisation effectiveness and a clear view of the customer expectations in this area.

10. Effect of peptides' binding on the antimicrobial activity and biocompatibility of protein-based substrates Maja Kaisersberger Vincek, 2017, doktorska disertacija Opis: This work reveals the effect of coupling approach (chemical by using carbodiimide chemistry and grafting-to vs. grafting-from synthesis routes, and enzymatic by using transglutaminase) of a hydrophilic ε-poly-L-lysine (εPL) and an amphiphilic oligo-acyl-lysyl (OAK) derivative (K-7α12-OH) to wool fibers and gelatine (GEL) macromolecules, respectively, and substrates antibacterial activity against Gram-negative E. coli and Gram-positive S. aureus bacteria after 1–24 h of exposure, as well as their cytotoxicity. Different spectroscopic (ultraviolet-visible, infrared, fluorescence and electron paramagnetic resonance) and separation techniques (size-exclusion chromatography and capillary zone electrophoresis) as well as zeta potential and potentiometric titration analysis, were performed to confirm the covalent coupling of εPL/OAK, and to determine the amount and orientation of its immobilisation.
The highest and kinetically the fastest level of bacterial reduction was achieved with wool/GEL functionalised with εPL/OAK by chemical grafting-to approach. This effect correlated with both the highest grafting yield and conformationally the highly-flexible (brush-like) orientation linkage of εPL/OAK, implicating on the highest amount of accessible amino groups interacting with bacterial membrane. However, OAK`s amphipathic structure, the cationic charge and the hydrophobic moieties, resulted to relatively high reduction of S. aureus for grafting-from and the enzymatic coupling approaches using OAK-functionalised GEL.
The εPL/OAK-functionalised GEL did not induce toxicity in human osteoblast cells, even at ~25-fold higher concentration than bacterial minimum inhibitory (MIC) concentration of εPL/OAK, supporting their potential usage in biomedical applications.
It was also shown that non-ionic surfactant adsorbs strongly onto the wool surface during the process of washing, thereby blocking the functional sites of immobilized εPL and decreases its antibacterial efficiency.
