AbstractWe investigate the role of aerosols in the transmission of SARS-CoV-2 in public spaces. Direct measurement of aerosol concentrations however has proven technically difficult; we propose the use of handheld particle counters as a novel and easily applicable method to measure aerosol concentrations. This allow us to perform measurements in typical public spaces, each differing in volume, number of people and ventilation rate. These data are used to estimate the relation between aerosol persistence time and the risk of infection with SARS-CoV-2.

This article analyzes the main problems of urban public spaces, because today public spaces can determine the future of cities. It is noted that parks are multifunctional public spaces in the urban environment, as they are an important element of the citywide system of landscaping and recreation, perform health, cultural, educational, aesthetic and environmental functions. The article notes that the need for easily accessible and well-maintained urban parks remains, however, the state of parks in many cities of Russia remains unsatisfactory, requiring reconstruction. A brief historical background of the Park of Culture and Rest of the Soviet period in Omsk is expounded, the analysis of the existing territory of the Park is presented. It is revealed that the Park, being the largest public space in Omsk, does not meet the requirements of modern urbanism, although it represents a great potential for designing the space for the purpose of recreation of citizens. Performed functional zoning scheme of the territory of the Park in question, where its division into functional areas destined for active recreational users of the Park is presented, considered the interests of senior citizens, people with limited mobility, etc. Reconstruction of Parks of the Soviet period can provide the city with additional recreational opportunities, as well as increase its tourist attractiveness.
