In the context of climate change and rapid urbanization, the construction sector plays a crucial role in achieving sustainable development. This paper analyzes the role of BIM, IoT, Digital Twins, and AI in green building development, with emphasis on South Korea. Using a qualitative case study approach (Songdo, Sejong, Busan Eco Delta City), the findings show that integrating these technologies optimizes energy performance and resource management. Successful implementation requires institutional support, data standardization, and long-term strategy. South Korea's experience offers valuable lessons for advancing sustainable construction in Serbia.

Urban air pollution represents one of the most significant environmental health risks worldwide, particularly in rapidly developing urban areas. Epidemiological studies consistently link major air pollutants-including particulate matter (PM2.5 and PM10), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂)-with a range of adverse health outcomes. This study analyzes the health impacts of urban air pollution, with a focus on respiratory and cardiovascular diseases, and evaluates current prevention and control strategies. The review synthesizes findings from 11 key peer-reviewed studies, including epidemiological analyses, systematic reviews, and policy evaluations, published between 1993 and 2024. The findings indicate that long-term exposure to PM2.5 is associated with a significant increase in the risk of chronic respiratory conditions, cardiovascular diseases, and premature mortality. Landmark cohort studies demonstrate a 6-15% increase in cardiovascular mortality per 10 μg/m³ rise in PM2.5 exposures. Vulnerable populations, including children and the elderly, are particularly susceptible to these effects. In addition, the synthesis of available evidence highlights that integrated prevention strategies-combining policy measures (e.g., emission standards), urban planning solutions (e.g., green infrastructure, traffic management), and technological innovations (e.g., clean energy, emission control systems)-have proven effective in reducing ambient pollutant levels and associated health burdens.

Papaver rhoeas L. (Papaveraceae) is an annual grass native to many regions of the world, which is known to possess several pharmacological properties. It is also known that represent a rich source of anthocyanins. In this study, the content of the anthocyanin was determined in the examined various extracts of fresh petals by HPLC analysis. The most represented anthocyanins in the extracts of Papaver rhoeas L. are delphinidin-3-O-glucoside, cyanidin-3-O-glucoside, cyanidin-3-O-rutinoside, peonidin-3-O-glucoside, petunidin-3-O-glucoside, petunidin-3-acetylglucoside, and delphinidin-3-p-coumaroylglucoside. Acyl derivatives of anthocyanins in the water extract have not been identified. By comparing the contents of individual anthocyanins, the glycosides (polar) are better extracted with 50% alcohol solution, and their acyl derivatives are better extracted with pure alcohol. The water solution is the least suitable for anthocyanin extraction.
