The article deals with the complex dynamics of depopulation in rural areas in Serbia. Although the topic has been very topical in recent decades and research has long identified the causes and consequences of depopulation in numerous regions in Europe, there seems to be no systematic approach to the implementation of policies for the management of abandoned areas. We started from already known factors contributing to depopulation, including economic, social and environmental dimensions. Based on previous research, historical trends and a statistical database, we attempted to represent depopulation as a spatial process that has its own size, structure and consequences, using a new, quantitative methodology for grouping abandoned areas into clusters as basic units of dispersal of depopulated areas. The aim of the work was to quantitatively determine the size and structure of the depopulated area in Serbia after the 2022 census. The study opened up new fields of research for the future use of depopulated space, but also offered certain solutions for policy makers, researchers and municipalities struggling with the challenges of depopulation. The results of the work show the existence of 47 abandoned clusters in 10 administrative regions of Serbia, which is 17 more than in the 2011 census. Further homogenization and consolidation of clusters was found in the statistical regions: Toplička, Zaječarska, Jablanička, Pirotska and Raška region, i.e. an increase in the total depopulated area as well as its spatial expansion towards the north of the country.

This study investigates the enhancement of condition and the extension of service life in architectural structures of shopping malls through the application of a hybrid methodological framework that integrates Life Cycle Assessment (LCA) and Service Life Planning (SLP). Thisresearch identifies key parameters related to physical performance, sustainability indicators, and functional characteristics of architectural systems that are subject to deterioration and shifting market conditions during the operational phase. The methodology encompasses a theoretical synthesis of LCA/SLP principles and advances in modeling for both the integrated design of new facilities and the monitoring and renewal of existing ones—from data collection and early-stage planning, through construction, use, and maintenance, to end-of-life phases. A second component of the model focuses on quantitative assessment and condition forecasting, based on Markov chain modeling, applied to the case study of the “Deva 1” shopping mall in Serbia. The results demonstrate the model’s ability to correlate physical condition indices with predictive service life scenarios.This study further contributes by integrating time-dependent impact categories, usage profiles, and planning parameters into a unified evaluation matrix, which can be applied to the development and improvement of systems aimed at enhancing the structural, functional, esthetic, and indirectly economic value of shopping mall buildings throughout their entire life cycle—from an architectural perspective.

In order to avoid unnecessary applications of Miller-Rabin algorithm to the number in question, we resort to trial division by a few initial prime numbers, since such a division take less time. How far we should go with such a division is the that we are trying to answer in this paper?For the theory of the matter is fully resolved. However, that in practice we do not have much use. Therefore, we present a solution that is probably irrelevant to theorists, but it is very useful to people who have spent many nights to produce large (probably) prime numbers using its own software.Comment: 8 pages, 6 figure

This study examines shopping mall revitalization models from the perspective of the building life cycle, employing Life Cycle Assessment (LCA) and Service Life Planning (SLP) methodologies. The primary objective is to identify key criteria for extending the service life of facilities while preserving their functionality, technical performance, and sustainability. Through a case study of a shopping mall in Serbia, the research demonstrates that integrated design, combined with continuous condition monitoring and timely decision-making, can ensure a balance between energy efficiency, architectural flexibility, and market relevance—ultimately resulting in the extension of the building’s service life. Particular emphasis is placed on the architect’s role within the stakeholder system in shaping durable and adaptable structures that meet contemporary urban demands and environmental standards. The findings suggest that planned maintenance, supported by ongoing performance assessment, is essential for the timely reactivation of facilities through remodeling and for the prevention of premature obsolescence.

Architectural education is increasingly expected to prepare students to base design decisions on research, evaluation and a clearer understanding of user needs. This study examines the position of Evidence-Based Design (EBD) in architectural education, focusing on the documented curricular visibility of EBD-related content and the recognition of EBD as a coherent design methodology. The research combined structured curriculum mapping of 44 institutional cases across Europe with a questionnaire survey of 213 students and academic staff from 13 higher education institutions in five countries of the former Yugoslav region. Curriculum mapping showed broad EBD-related visibility: 41 of 44 cases (93.2%) were coded as Direct or Strong, while only 5 (11.4%) met the criteria for a Direct EBD connection. Thirty-five institutions (79.5%) included at least three of the five EBD-related thematic dimensions. The survey showed limited familiarity with EBD and low reported curricular exposure, but high interest in EBD application and research. Taken together, the findings indicate a convergent but non-causal pattern of broad curricular visibility alongside limited explicit EBD labelling and recognition. The results suggest that already present themes, methods and approaches aligned with EBD principles could be more clearly integrated within an evidence-based design reasoning framework.

Previous studies in the field of architectural and interior design of patient rooms in secondary and tertiary healthcare institutions in the Republic of Serbia have highlighted the need for access to regulatory documents that legally define the requirements for the planning, design, and construction of such facilities. A key issue identified is the absence of a unified and comprehensive list of easily accessible legal and regulatory acts. The aim of this paper is to compile a complete inventory of the relevant legal frameworks and to evaluate both the scope and quality of their content. The research methodology combines literature review, analytical and synthetic approaches, and comparative analysis. The findings point to an urgent need for reform of the existing regulatory system governing the planning and development of healthcare institutions in the Republic of Serbia.
