Opis: This paper aims to examine how the gig economy, as a global trend that is transforming labour markets worldwide, manifests itself in a smaller economy such as Slovenia. Specifically, the paper focuses on how this trend is manifested among Slovenian freelancers, with an emphasis on generational differences. Descriptive statistics, the Mann-Whitney U test and the Chi-square test, were used in the study to explore perceptions and generational differences and to determine whether they are statistically significant. The results show that both younger and older individuals are likely to choose freelance work due to the need for flexibility and independence in project selection, reflecting their desire for greater control over their personal and professional lives. In addition, the research reveals a perception of insufficient support for such new types of careers and a need for educational programmes to improve skills and awareness of the digital labour market. The findings suggest the need for targeted policy measures to support freelancers of different age groups by implementing comprehensive government programs that promote lifelong learning and upskilling, enable the development of local coworking spaces, provide digital market information and include entrepreneurship education and digital literacy in school curricula to strengthen freelance careers, making them sustainable and contributing economically to regional development.

Opis: This study examines the gig economy in Slovenia, with a particular emphasis on the perceived benefits and challenges for gig workers within this emerging labour model. The research aims to capture the implications of flexible, project-based employment in a smaller European context, as this trend becomes increasingly prevalent globally. A quantitative approach was employed to survey 34 gig workers in Slovenia. The survey analysed their demographic characteristics, reasons for engaging in gig work, and the benefits and challenges they experience. In the findings, 64% of respondents specifically identified schedule flexibility as a predominant benefit of gig work. However, it also uncovers substantial challenges, including increased market competition and a lack of social benefits. Moreover, the research suggests that perceptions of the gig work benefits are widely acknowledged across various age groups and educational levels, with no significant variation. Nevertheless, the findings indicate a gender disparity in gig work perceptions, with males perceiving higher levels of financial freedom and professional development than women. This research suggests the need for policies aimed at ensuring equity and further research into harmonizing gig work with supportive labour market policies.

Opis: The behaviour of horizontal floor diaphragms plays a crucial role in ensuring the overall response of a building during earthquakes, as the stiffness of these diaphragms determines whether the structure will act as an integrated system. If the diaphragms do not exhibit sufficient stiffness, differences in the redistribution of forces on wall elements arise, increasing the risk of significant deformations and even local damage, which is commonly observed in earthquake-affected areas. Additionally, flexible diaphragms heighten the risk of torsional effects. Due to these factors, more attention should be given to the response of buildings with flexible diaphragms. Eurocode standard specifies general requirements under which diaphragms should be considered rigid within their plane, depending on the maximum diaphragm moment. However, specific guidelines regarding the geometric and material properties of elements that significantly impact seismic behaviour are not included in the existing European standards. This served as a basis for conducting a numerical study analysing the in-plane behaviour of floor elements made from different materials. This study, limited to a simple box-shaped structure with masonry walls, symmetrical in both orthogonal directions, evaluated and thoroughly analysed the deformations for different types of diaphragms, including prefabricated wooden frame-panel floors, CLT panels, and reinforced concrete slabs. Special emphasis was placed on wooden structural elements due to the increased demand for timber construction, as the behaviour of these elements needs to be properly studied, especially in seismic regions. The study results were obtained through FEM analysis using the SCIA Engineer software, version 22. The modelling of elements was carried out considering the orthotropy of brick wall and wooden ceiling elements, as well as simulating the appropriate shear stiffness of the connecting means.

Opis: The article deals with the issue of providing suitable voltage profiles and preventing congestion of network elements in distribution networks. Active network elements and network users’ energy flexibility services are used to provide a suitable voltage profile and prevent congestion in distribution networks. The discussed active network elements include a transformer with on-load tap changer, reactive power compensation devices, energy storage systems, distributed energy resources, and network users’ energy flexibility services, where the active consumers adjust their consumption, production and storage of energy. Based on the Backward Forward Sweep load flow computation method, the case studies are performed for the discussed low voltage distribution network, where the measurement results were available. The case studies for preventing overload of the distribution transformer are performed using a battery energy storage system and network users’ energy flexibility services. The case studies for providing suitable voltage profiles are performed using all listed active elements and a combination of different active elements. In addition, to provide suitable voltage profiles, the existing conductors are replaced with conductors of a larger cross-section. Technically acceptable solutions that can provide a suitable voltage profile and prevent the overloading of network elements in the most demanding operating conditions are presented in this article.
