Integrating GIS, Climate Hazards, and Gender Safety in Railway Networks
Railway transport plays a crucial role in sustainable and low-carbon mobility; however, the safety and resilience of railway systems are increasingly challenged by aging infrastructure, spatial inequality, and intensifying climate extremes. These challenges are particularly evident in Serbia, where railway stations in rural and peripheral areas often lack adequate safety infrastructure, accessibility, and climate-adaptive design, especially affec…

Universal Snow Avalanche Modeling Index Based on Safi–Flow-R Approach in Poorly-Gauged Regions
Most high-mountain regions worldwide are susceptible to snow avalanches during the winter or all year round. In this study, a Universal Snow Avalanche Modeling Index is developed, suitable for determining avalanche hazard in mountain regions. The first step in the research is the collection of data in the field and their processing in geographic information systems and remote sensing. In the period 2023–2024, avalanches were mapped in the field, …
Healthcare Professionals’ Knowledge and Behaviors Regarding Drug–Dietary Supplement and Drug–Herbal Product Interactions
Given the widespread use of dietary supplements (DS) and herbal products (HP), healthcare professionals (HCPs) will increasingly encounter patients who use these preparations with conventional drugs and who need their services to reduce the consequences of adverse therapeutic outcomes. The aim of our survey was to assess the knowledge and behaviors of HCPs regarding the risk of potential drug−dietary supplement (DDSIs) and drug−herbal product (DH…
Supporting Tourism by Assessing the Predictors of Covid-19 Vaccination for Travel Reasons
The persistence of the SARS-CoV-2 virus imposed vaccination passports for traveling in most countries. We investigated psychological factors that predict the intention to vaccinate for travel. In a cross-sectional study, we examined how demographic variables, vaccination status, perceived risk of infection and severity of disease contracted at travel destination, safety and effectiveness of vaccines against contracting COVID-19 during travel, and…
Updated Trewartha climate classification with four climate change scenarios
The Updated Trewartha climate classification (TWCC) at global level shows the changes that are expected as a consequence of global temperature increase and imbalance of precipitation. This type of classification is more precise than the Köppen climate classification. Predictions included the increase in global temperature (T in °C) and change in the amount of precipitation (PA in mm). Two climate models MIROC6 and IPSL-CM6A- LR were used, along w…
Predictors of Changes in Travel Behavior during the Covid-19 Pandemic
This study investigates travel behavior and psychosocial factors that influence it during the COVID-19 pandemic. In a cross-sectional study, using an online survey, we examined changes in travel behavior and preferences after lifting travel restrictions, and how these changes were influenced by exposure to COVID-19, COVID-19 travel-related risk and severity, personality, fear of travel, coping, and self-efficacy appraisals in the Romanian populat…
Shaping Sustainable Urban Environments by Addressing the Hydro-Meteorological Factors in Landslide Occurrence
Romania is one of the countries severely affected by numerous natural hazards, where landslides constitute a very common geomorphic hazard with strong economic and social impacts. The analyzed area, known as the "Ciuperca Hill", is located in Oradea (NW part of Romania) and it has experienced a number of landsliding events in previous years, which have endangered anthropogenic systems. Our investigation, focused on the main causal factors, determ…
Landscape Changes through History Following the Example of the Former Narrow-Gauge Railroad Belgrade (Čukarica–Obrenovac) Serbia
The process of urbanistic changes in space and time is not a steady one, nor always the same, followed by dissipation and demolition of objects, and the construction of new ones does not necessarily stabilize the process of changes within space. The changes that took place on the former narrow-gauge railroad Belgrade–Obrenovac reflect the changes in historical, cultural, and urban processes as well. The strategic plan of the development of the ci…
Roma Inner Migration Tradition Between Social Inclusion and the Protection of Natural Resources
Using the existing knowledge about the social and cultural characteristics of the Roma in Serbia, possible connection between Roma population and preserving of natural resources was established. This analysis acquired in social and other related studies, as well as the data obtained through the GIS (geographical information system) methodology, was used for determining the spatial distribution of Roma settlements and activities of the Roma commun…
