Opis:
The particulate matter (PM10, PM7, PM4, PM2.5 and PM1) mass concentrations in Bejaia City, Algeria, over the course of one week, from July 8 to July 14, 2015, have been presented for the first time. The study covered eight urban sampling sites and 169 measurements have been obtained. The average city-wide PM10 and PM2.5 concentrations measured during this sampling were 87.8±33.9 and 28.7±10.6 μg/m3, respectively. These results show that the particulate matter levels are high and exceed the World Health Organization Air Quality Guidelines (WHO AQG) and European 24-hour average limit values (50 μg/m3for PM10and 25 fig/m3for PM2.5). The PM1, PM2.5, PM4 and PM7 fractions accounted for 0.15,0.32,0.56 and 0.78, respectively, of the PM10 concentrations. The analysis revealed that variations of PM concentration in the study region were influenced primarily by traffic. Lower PM10 concentrations (21.7 and 33.1 μg/m3) were recorded in residential sites, while higher values (53.1, and 45.2 μg/m3) in city centers.

Opis:
The study shows a possible way of analyzing the diversity of ownership forms in non-urban areas, with particular focus on land co-ownership. The data in cadastral databases was processed with the use of the relational model which applied information on the geometry of areal spatial objects and descriptive attributes. The paper presents also the results of the analysis of Nowy Sącz District with the area of 1.550 sq.km and containing approximately 200.000 parcels. The area is representative for many countries in Central and Eastern Europe, where unfavorable land fragmentation indices and complex ownership structures complicate investing processes and development of rural areas what results in progressive degradation of agricultural and cultural landscape. The results indicate that the co-ownership phenomenon affects 13% of parcels in the study area. However, it varies greatly depending on the village and ranges from 3 to 67% of total parcels number. Suggested methods of analyzing the ownership structure are of universal character. In spite of this, when used during analyses conducted in other countries, certain modifications are required. It is mainly caused by the differences in cadastral data models used in those countries.

Opis:
Many European agglomerations suffer from high concentrations of particulate matter (PM), which is now one of the most detrimental pollutants characterizing the urban atmospheric environment. This paper addresses the problem of PM10 pollution in the Warsaw metropolitan area, including very harmful fine fractions (PM2.5), and also some heavy metals. The analysis of air quality in the Warsaw agglomeration discussed in this study is based on results from computer modeling presented elsewhere, and refers to emission and meteorological data for the year 2012. The range of emissions considered in this analysis includes the main sectors of municipal activity: energy generation, industry, urban transport, residential sector. The trans-boundary inflow of the main pollutants coming from distant sources is also taken into account. The regional scale computer model CALPUFF was used to assess the annual mean concentrations of major pollutants in the urban area. The results show the regions where the air quality limits are exceeded and indicate the dominant sources of emission which are responsible for these vio-lations (source apportionment). These are the key data required to implement efficient regulatory actions.

The municipalities in Slovakia have a duty to separate biodegradable municipal waste (BDMW) from family houses. This duty can be achieved by home composting or by collection of green waste in bio-bins, which are regularly emptied by a collection company. The collected waste is recycled in a composting plant. The conducted research was focused on identifying the composition of the collected green waste and comparing the environmental behaviour of residents in villages and towns. The analyses conducted showed that the separated BDMW from the urban population has a higher rate of contamination, but a lower rate of compostable kitchen waste compared to the residents in villages.

Opis:
The commonness of metal contamination, even at considerable distances from industrial centers and intensively used economic areas, has become the interest of many researchers. The issue of evaluating the state of the environment with the help of living organisms has become a very important part in the control of the natural environment. Honey bee (Apis mellifera L) is a good bioindicator as it is inextricably linked to the natural environment in which it lives. The aim of the research, and at the same time the main assumption of the study, was to evaluate the effectiveness of honeybees (Apis mellifera L) as bioindicators for the presence of Cu, Cr, Zn, Mn, Fe in the urban area (example of Bialystok city). The study includes pilot studies covering three sampling periods (March, June and September 2015). Analyses of metals were made by ASA method. The results showed the presence of Cu, Cr Zn, Mn and Fe in all bees samples. An increased content of Cr in bees was also found, which may be the result of the presence of this element in the environment (air, soil, water, plants, pollen) and in the impregnation agent applied to protect wooden elements of the bee hive. The research showed seasonal variation of metals in bees bodies. The main sources of studied metals in bee samples seem to be motorization, industry, and municipal economy within the urban area. Statistical calculations showed a common origin of majority of studied metals. Bee studies for metals contents can be an important element of a bio-monitoring of changing natural environment as a consequence of anthropogenic activity.

Opis:
The GPS system is widely used in navigation and the GPS receiver can offer long-term stable absolute positioning information. The overall system performance depends largely on the signal environments. The position obtained from GPS is often degraded due to obstruction and multipath effect caused by buildings, city infrastructure and vegetation, whereas, the current performance achieved by inertial navigation systems (INS) is still relatively poor due to the large inertial sensor errors. The complementary features of GPS and INS are the main reasons why integrated GPS/INS systems are becoming increasingly popular. GPS/INS systems offer a high data rate, high accuracy position and orientation that can work in all environments, particularly those where satellite availability is restricted. In the paper integration algorithm of GPS and INS systems data for pedestrians in urban area is presented. For data integration an Extended Kalman Filter (EKF) algorithm is proposed. Complementary characteristics of GPS and INS with EKF can overcome the problem of huge INS drifts, GPS outages, dense multipath effect and other individual problems associated with these sensors.

Opis:
The aim of the presented work was to show that contemporary researchers recognize the potential of urban gardening in improving urban retention, and that the contemporary scientific literature mentions specific problems-indicators of retention that can be useful for developing guidelines for authorities and gardeners on the management and development of urban gardens, such as allotments and community gardens, considering their role as a retention tool. In this study, a meta-analysis of peer-reviewed scientific articles from popular scientific databases such as Web of Sciences, Science Direct, Springer and MDPI was performed, which was, besides literature analysis, the main method of research. Definitions of urban garden retention indicators were developed, which are: rainwater/stormwater infrastructure (collecting rainwater water – special infrastructure); watering systems (system for providing water strait to plants); planting type (garden plants: flowers, vegetables, fruits, herbs on beds – no turf: lawn or turf with dicotyledonous plants). The most frequent groups of indicators in the articles were also identified. The study also analyzed the distribution of surveyed articles between continents, noting the overrepresentation of articles from North America and the absence of articles from South America.

Flood inundation processes in urban areas are primarily affected by artificial factors such as drainage facilities, local alterations of topography and land uses. The objective of this study is to examine the capability of hydrological model SI-MODAS to estimate runoff and investigating the utilization of storage well in controlling runoff in a residential area. The result of the estimated runoff from the hydrological model was compared with the existing capacity of the drainage channel to identify which channel experienced the problem of inundation. The location of inundation was used to determine the location and number of storage well. The results showed that SIMODAS model could be applied in runoff analyses with 8.09% of relative error compared with runoff depth from field measurement. The existing capacity of the channel could not accommodate runoff Q10yr where the inundation discharge was approximately 0.24 m3·s–1 (at outlet point 1) and 0.12 m3·s–1 (at outlet point 2). The inundation problem was overcome by using a combination system between channel normalization (reduce 35% of total inundation discharge) and storage well system (reduce 65% of total inundation discharge). The storage well was designed at 20 locations (at outlet point 1) and 16 locations (at outlet point 2) which each well had a discharge of 0.0058 m3·s–1. The storage well combined with channel normalization could be used as an alternative way to solve inundation problems in a residential area considering the constraint of land space limitation in the urban area.

Opis:
Chlorofluorocarbons, both of natural and industrial origin, currently exist as trace gases in the entire human environment. The CFCs cause ozone depletion in the stratosphere. Moreover, CFCs and $SF_6$ take part in intensification of the greenhouse effect. On account of international agreements, the measurements of CFCs and $SF_6$ in air were started. Measurement stations of these gases were situated at places outside of urban areas influence and gathered on the world-wide program - AGAGE (Advanced Global Atmospheric Gases Experiment). One of these stations is Mace Head (Ireland, 53° N, 10° W), which participates in AGAGE since 1987 and in InGOS (Integrated non-$CO_2$ Greenhouse Gas Observing System) program since 2011. Similar research is also conducted in Central Europe, in urban area of Kraków (Poland, 50° N, 19° E) since 1997. This work discusses the results of concentration measurements (1997-2012) of selected halocarbons and $SF_6$ in Kraków. To obtain concentrations of the measured compounds the mathematical procedure has been used, where concentrations were calculated using a five points Lagrange interpolation method. Daily arithmetic means of the measured mixing ratios and their standard deviations were determined. Based on these data, efficiency of Montreal Protocol legislation, implemented in Poland could be assessed.

Opis:
It is possible to make analyses within the field of GIS applying cellular automata. One of the purposes of socio-economic geography is indirect understanding of the phenomenon by analyzing spatial patterns and inferring spatio-temporal processes looking rather for local hotspots. The cellular automata are the tool both for spatio-temporal inferring based on local conditions and data visualization. The evidence is the case study of spatial simulation of Warsaw Urban Area (Poland). The author verifies the hypothesis that the present layout and extent of the Warsaw agglomeration determines further directions of the city's spatial development. To this end, he employs a method based on cellular automata theory.

Opis:
One of the elements interfering road safety are weather conditions. Supporting instrument for identification of threats are weather information systems. They are responsible for control and minimizing disadvantageous impact of atmospheric phenomenon’s on traffic. This research presents technologies used in road meteorology. Wide range of discussed systems include intrusive sensors that require mounting in road surface, as well as non-intrusive ones. One of the modern solutions are mobile sensors that allows to monitor current weather situation in variable locations. This idea seems to be an useful instrument supporting traffic management in urban areas. Mobile technology enables fast intervention of traffic authorities and eradicating dangerous effects on road network. The research elaborates on weather exemplary data collected by mobile sensor. Authors also established possible solution for monitoring and control atmospheric conditions using public transportation system in urban area.

Opis:
Over time, fragmentation of semi-natural habitats in urban areas has become a pressing concern, disrupting ecological processes within cities. The focus on preserving open ecosystems has grown, highlighting the need to enhance resilience in urban riverside areas for effective ecosystem restoration. Comprehensive studies on river valleys, considering both hydrology and ecology, play a crucial role in urban river ecosystem development. Our article explores the potential of protective zones with urban vegetation and watercourses as Nature-based Solution within Krakow's ongoing riverine park system development. The study's cross-sections in the River Park area revealed dominant velocities ranging from 0.67 to 2.0 m s-1 for SWQ (mean annual maximum flow) and below 0.67 m s-1 for Q1% (1% annual exceedance probability flow). The hydrological analysis accurately captured the natural river bed channels' curvature, providing the basis for a two-dimensional mathematical model to visualize the hydraulic structure of protected sites. Integrating water and greenery management systems in urban areas offers significant potential for adapting to climate change, mitigating extreme weather events. Our research's novelty lies in applying 2D hydraulic modeling, demonstrating how River Parks can serve as climate change mitigation solutions in urban environments.

Opis:
Urban changes occur as a result of new constructions or destructions of buildings, extensions, excavation works and earth fill arising from urbanization or disasters. The fast and efficient detection of urban changes enables us to update geo-databases and allows effective planning and disaster management. This study concerns the visualization and analysis of urban changes using multi-period point clouds from aerial images. The urban changes in the city centre of the Konya Metropolitan area within arbitrary periods between the years 1951, 1975, 1998 and 2010 were estimated after comparing the point clouds by using the iterative closest point (ICP) algorithm. The changes were detected with the point-to-surface distances between the point clouds. The degrees of the changes were expressed with the RMSEs of these point-to-surface distances. In addition, the change size and proportion during the historical periods were analysed. The proposed multi-period change visualization and analysis method ensures strict management against unauthorized building or excavation and more operative urban planning.

Samples of lichens were taken in the autumn of 2013, from Betula pendula Roth, Fraxinus excelsior L., Acer platanoides L., Acer Pseudoplatanus L., Populus sp. trees and other broad-leaved trees growing within the city limits of Słupsk. The sampling stations were located in housing estates, green urban parks, near streets with heavy traffic and close to industrial plants. The aim of the study was to evaluate the pollution of the municipal environment of Słupsk with selected heavy metals using for this purpose thalli of three lichen species: Hypogymnia physodes, Parmelia sulcata and Xanthoria parietina, and to compare their accumulative properties. The heavy metal content in lichens was determined by atomic absorption spectrometry. The highest concentration of heavy metals was discovered in lichens collected in the city centre, while the lowest concentrations were found in parks and green areas. The largest quantities of Ni and Pb were accumulated by the lichen species H. physodes, most Zn and Fe accumulated in the lichen X. parietina, whereas Mn accumulated in similar amounts in all the tested species. A strong direct proportional relationship between the content of Zn and Fe, Fe and Cu, Zn and Cu in thalli of lichens was revealed. Some similarity between the Pb-Cu and Pb-Fe correlations was found as well as that of Pb-Mn in thalli of P. sulcata and X. parietina, along with a series of statistically significant differences between the examined species of lichen related to pH and the volume of accumulated heavy metals in thalli. The most significant differences in the content of heavy metals in thalli assessed in series of pairwise comparisons including (i) H. physodes vs P. sulcata, (ii) P. sulcata vs X. parietina and (iii) H. physodes vs X. parietina were found for (i') Pb, Cu and Fe, (ii') Ni and (iii') Pb, Ni, Cu and Fe, respectively.

Opis:
The value of terrestrial carbon sequestration in urban areas, due to lack of vegetation as a carbon sink, is rarely studied. In fact, urban areas have high carbon emission values, which must be minimised. On the other hand, the value of carbon sequestration in urban areas is very dynamic due to natural factors from the environment and non-natural factors from anthropogenic activities. The main objectives of this study are to identify the carbon dioxide sequestration in urban areas, especially in tropical climates, and to determine the dynamics of carbon sequestration in urban areas for a year. The results show that carbon sequestration in tropical urban areas has a significant value compared with urban areas in temperate climates. This condition happens because there are still green open spaces in gardens and agricultural lands. The value of carbon sequestration in this tropical urban area experiences monthly dynamics caused by rainfall variation and anthropogenic activities, such as land conversion and plant type conversion in agricultural lands.

Opis:
Background. Modern research of health determinants and health-related behavior patterns places a particular emphasis on the assessment of physical activity levels in various social and professional groups. The deficit of physical activity has become a common cause of serious diseases. Following the ecological model of health behavior, physical activity as a biological and cultural phenomenon can be indirectly modified by such interpersonal factors as age, sex, somatic traits and education. Objectives. The aim of the present study was the identification and assessment of habitual physical activity of adult inhabitants from the Katowice Urban Area with regard to selected physical traits and social determinants. Material and methods. The study was carried out in the Katowice Urban Area in May and June, 2012-2014. The research material comprised 2,173 inhabitants, including 1,017 women and 1,156 men, aged 30 to 65 years. The respondents’ habitual physical activity was assessed with the use of the International Physical Activity Questionnaire - Short Version (IPAQ-SF). The obtained data on the respondents’ physical activity were compared with the American College of Sports Medicine (ACSM) recommendations Results. The results of the study showed that the frequency and duration of high-intensity physical activity and duration of moderate-intensity physical activity were significantly greater in the male inhabitants. The age was also a significant factor affecting the levels of high-intensity physical activity in men. Body build was not a significant determinant of the frequency and duration of physical activity in both men and women from Katowice. The education level only affected the level of physical activity in men. Sex, age, and education of the respondents were statistically significant determinants of their level of fulfilment of the ACSM recommendations. Conclusions. Propagation of physical activity among adults and the elderly, and women in particular, remains a continuing challenge facing health promotion professionals.
Wprowadzenie. W badaniach uwarunkowań zdrowia i zachowań zdrowotnych współczesnych pokoleń, szczególnego znaczenia nabiera ocena aktywności fizycznej różnych grup społeczno-zawodowych. Niedobór wysiłków fizycznych jest bowiem coraz powszechniej przyczyną groźnych schorzeń. Zgodnie z modelem ekologicznym aktywność fizyczna jako zjawisko nie tylko biologiczne, lecz także kulturowe może być w sposób pośredni modyfikowane m.in. przez takie czynniki intrapersonalne, jak: wiek, płeć, cechy somatyczne, czy wykształcenie. Cel. Celem pracy jest diagnoza i ocena parametrów nawykowej aktywności fizycznej osób dorosłych zamieszkujących aglomerację katowicką w świetle wybranych czynników somatycznych i społecznych. Materiał i metody. W badaniach ankietowych przeprowadzonych na terenie aglomeracji katowickiej w latach 2012-2014 roku wzięły udział 2173 osoby, w tym 1017 kobiet i 1156 mężczyzn, w wieku od 30 do 65 lat. Do oceny nawykowej aktywności fizycznej wykorzystano kwestionariusz International Physical Activity Questionnaire Short Version (IPAQ-SF). Uzyskane informacje o aktywności fizycznej badanych pozwoliły na ich konfrontację z kryteriami zalecanymi dla uzyskania korzyści zdrowotnych przez ekspertów ACSM. Wyniki. W badaniach wykazano u badanych znamienne zróżnicowanie płciowe w częstości i czasie trwania aktywności fizycznej o wysokiej intensywności oraz czasie trwania wysiłków umiarkowanych, na korzyść mężczyzn. Dostrzeżono również, że wiek znamiennie różnicował częstość podejmowania wysiłków fizycznych o wysokiej intensywności przez badanych mężczyzn. Wśród badanych mieszkańców aglomeracji katowickiej, parametry budowy somatycznej nie determinowały istotnie w obu grupach płci częstości oraz czasu trwania aktywności fizycznej. Wykształcenie okazało się czynnikiem modyfikującym poziom aktywności fizycznej wyłącznie u przedstawicieli płci męskiej. Płeć, wiek oraz poziom wykształcenia ankietowanych katowiczan znamiennie determinowały także stopień wypełnienia przez nich zaleceń ACSM. Wnioski. Popularyzowanie aktywności fizycznej wśród osób dorosłych i starszych, szczególnie kobiet jest stale aktualnym wyzwaniem dla specjalistów promujących zdrowie.

Opis:
The purpose of the present paper is to attempt to identify relations between the changing perception of leisure and the creation of tourism and recreational spaces in urban areas. The authors focus in particular on changes associated with the so-called ‘third wave’ (TOFFLER 2001), time compression (NIEZGODA 2017), and departure from synchronization. These considerations are illustrated by an analysis of the recreational activity of Szczecin residents and of tourists, and attempt identifying the relations between recreational space and tourism space. With the constant compression of leisure time, tourism activities become more similar to the leisure activities of residents, which means both types occur in the same environment. Urban recreational and tourism spaces overlap in a way that makes it impossible to separate them, but still allows the distinction of certain sub-spaces where either tourism or recreational behavior prevails.

Opis:
Biodiversity declines due to unplanned urbanization as well as anthropogenic activities. It has already been documented that native flora and fauna are disappearing as an impact of biodiversity loss. There should be urgent need to restore our lost habitats through conservation techniques. The present study was aimed to conserve and restore lost habitat of pollinators with special reference to butterflies in an urban area through setting up a garden. The study was divided into two phases. In the first phase survey of butterflies found within an unmanaged garden in the campus (Lady Brabourne College, Kolkata) was performed prior to construction activity (May 2012 to October, 2012) and it was observed previously total 31 species of butterfly visited the garden. Developmental activities caused a sharp decline in their population causing an approach to relocate our garden in another area of college campus. In the second phase, setting up a garden in an alternative sites of same campus with plantation of host plants preferred by butterfly species was done and observed for butterfly visit. A slow increase in sighting over a study period of two years (between October, 2012 to June, 2015) was recorded. The results clearly indicate that total 43 species of butterflies were recorded in the garden including 9 species, which were not seen before and with 8 species completing their life cycles. In conclusion, declining of butterfly species can be increased and conserved through setting up of a garden. Presently the garden is flourishing but problems of increase in natural enemies as birds and other anthropogenic disturbances such as excess noise and vibration, street lighting, human interference etc. should be addressed in future within present conservation approach.

Opis:
Road transportation does an excellent job of connecting Savar's inner and outer areas, but it might be difficult for commuters to decide which mode of transportation to employ because residents of Savar come from a wide range of socioeconomic backgrounds. It is necessary to do in-depth research on the characteristics of people in the study region who choose different modes of transportation to achieve the goal of selecting a certain mode for their travel. Where a person lives can have a significant impact on their typical patterns of travel behavior. People who live closer to the center of things have access to a wider variety of amenities than those who live further away, and as a consequence, their travel patterns are distinct from one another. The study's findings indicate that several factors, including income, age, gender, and vocational qualities and goals, influence a commuter's preferred method of transportation. When it comes to selecting a mode of transportation, the most predictable factors to take into account are trip time and cost. After conducting research, it was found that most excursions are made from this place to Motijheel, Tejgaon, and Savar Export Processing Zone for their services, businesses, and jobs, respectively.

Problem kartowania klimatu obszarów miejskich jest niezmiernie złożony. Wynika on zarówno z wielkiej różnorodności przestrzennej występujących na obszarach zurbanizowanych typów klimatu lokalnego (mikroklimatów), jak i technicmych trudności ich opisu w świetle danych eksperymentalnych. W pracy podjęto próbę kartometrycmej charakterystyki powierzchni miasta z punktu widzenia tych jej cech, które odgrywają decydującą rolę w ksztahowaniu specyficznych warunków klimatycmych. Określono udział powierzchni sztucmych ogółem, powierzchni dachów domów o różnych wysokościach, powierzchni zieleni wysokiej (drzew) i niskiej (trawniki, pola) oraz obliczono parametr szorstkości wg formuły Lettau (frontal area index) dla dwóch kierunków wiatru.
The climatic researches on urban areas are very complicated. It is caused not only by a great spatial differentiation of local microclimates but by technical difficulties concerning the adequate way of describing them in compliance with experimental data as well. In this work, it has been made an attempt to characterize the urban surface with regard to all the features which determinate formation of individual climatic conditions. The percentage of artificial surface in general, surface of the roofs on buildings of different heights, the green area both trees (as high green surface) and lawns and fields (as low green surface) has been estimated. J,łesides,the roughness parameter, according to Lettau's formula (frontal area index) has been calculated for two different wind's directions (N, W).
