Povzetek: The situation in Slovenia in terms of the accessibility of public buildings for functionally impaired persons is concerning. Most often people with disabilities already face barriers when accessing the building (no disabled parking available, stairs leading to the entrance into the building, thresholds that are too high, doors too heavy to open, handles set too high, etc.) and then in the building itself (staircases, unadapted lifts, insufficiently large toilets, etc.). To show potential barriers to the functionally impaired as well as the building owners and maintenance staff, a method is presented for inventorying building accessibility for the functionally impaired using online tools. The method relies on relevant universal accessibility legislation and standards, and it is important because it facilitates an accurate and comparable evaluation of potential barriers and adaptations already in place. Thus, it functions both as a multifunctional framework for evaluating the accessibility of all buildings, which provides an overview of and displays potential barriers to building owners and maintenance staff, and as a guide to building accessibility for the functionally impaired. Also presented is the method’s implementation in the online system for inventorying building accessibility, which makes it possible to monitor building accessibility for the needs of the functionally impaired and provides an overview of the barriers detected for the building owners and maintenance staff.

Povzetek: According to Global North urban studies, the traditional low-rise mixed-function perimeter block is the most attractive urban morphology in terms of organization of space, time, values, and social interactions. This study examines how valid these basic theses are regarding the comfort of urban housing morphological types in Kyiv, the capital of Ukraine. We compare residents’ quality of life and analyse the differences in residents’ behavioural patterns and spatial perception in different morphological types of housing to identify distinguishing features of the most comfortable urban form. Using expert evaluation and surveys, we assess history; jobs; social, educational, and cultural services; environmental indicators; security levels; and public activity in three different neighbourhoods: Zhulyany (with detached houses), Podil (with low-rise perimeter blocks), and Rusanivka (with Soviet high-rises). The results reveal that the Soviet neighbourhood, Rusanivka, leads in terms of both objective indicators and residents’ perception as the most comfortable living area. This finding contradicts generally accepted theories about exemplary and attractive urban morphology. This preference is based on the planning and construction priorities of the unique social system of Rusanivka, where its human-centeredness and a thoughtful integrated approach are highly valued.

Povzetek: Today, the use of technological devices is commonplace among children, which has also diminished children’s presence in the city. Although children, as novel citizens, develop some of their skills (such as social, mental, and educational skills) in the city, many children face some kind of city exclusion. Therefore, the way the physical environment of their city is shaped and how children interact with it plays a principal role in child engagement. A child-friendly city can be a place to engage children using contemporary tools such as augmented reality (AR), which helps children communicate better and fosters abilities such as spatial cognition and physical and social skills in the physical and digital world. This study explores various examples and analyses the child-friendly city features of each. This article presents AR and its capabilities as a potential tool utilized in the city to pave the way toward a child-friendly mediated city – an inclusive social urban environment where children play or spend their leisure time and effectively mature into adulthood.

Povzetek: With the COVID-19 pandemic, technological advancements and investments accelerated to create an alternative to the real world that makes it possible for various activities and experiences to be handled online. Among these developments, the metaverse comes to the fore because it makes possible real and virtual experiences simultaneously, regardless of the time and space the user exists in, and it acts as a mediator and medium to bring these two environments together. This article discusses the possible impacts of advancements in the metaverse on (real) urban space considering the socio-spatial dialectic through theory synthesis and adaptation. An overall evaluation of the socio-spatial impacts of this is also included and opened up for discussion. Based on a literature review, it is expected that technological developments like the metaverse will introduce a new organization to physical and virtual socio-spatial relations, and new socio-technological groups will be created in them and by using them.

Povzetek: Purpose: Double flow-focusing nozzles (DFFNs) form a coaxial flow of primary liquid with microcrystalline samples, surrounded by secondary liquid and focusing gas. This paper aims to develop an experimentally validated numerical model and assess the performance of micro-jets from a DFFN as a function of various operating parameters for the water–ethanol–helium system, revealing the jet's stability, diameter, length and velocity. Design/methodology/approach: The physical model is formulated in the mixture-continuum formulation, which includes coupled mass, momentum and species transport equations. The model is numerically formulated within the finite volume method–volume of fluid approach and implemented in OpenFOAM to allow for a non-linear variation of the fluid's material properties as a function of the mixture concentration. The numerical results are compared with the experimental data. Findings: A sensitivity study of jets with Reynolds numbers between 12 and 60, Weber numbers between 4 and 120 and capillary numbers between 0.2 and 2.0 was performed. It was observed that jet diameters and lengths get larger with increased primary and secondary fluid flow rates. Increasing gas flow rates produces thinner, shorter and faster jets. Previously considered pre-mixed and linear mixing models substantially differ from the accurate representation of the water–ethanol mixing dynamics in DFFNs. The authors demonstrated that Jouyban–Acree mixing model fits the experimental data much better. Originality/value: The mixing of primary and secondary liquids in the jet produced by DFFN is numerically modelled for the first time. This study provides novel insights into mixing dynamics in such micro-jets, which can be used to improve the design of DFFNs.
