The paper defines and presents the forms of glacial relief formed, most likely, during the last Pleistocene glacial maximum (LGM). A graphic and textual presentation of almost all glacial forms is given on the entire territory of the Sara Mountains, on both sides of their main ridge, from Ljuboten in the NE to the source tributaries of the Radika River in the SW. Based on the height position and spatial development of glacial forms, the height of the snow line (ELA) was determined, glacier types were determined and defined, which is shown on two overview maps representing Pleistocene glacial morphology and reconstructed Pleistocene glaciers referring to the last Pleistocene glacial (MIS-2). Since these are the youngest glacial morphological traces on the Sara Mountains, they are the best preserved today.

Riverbank erosion and lateral channel migration are important geomorphological processes which cause various landscape, socio-economic, and environmental consequences. Although those processes are present on the territory of Serbia, there is no available data about the soil loss caused by riverbank erosion for the entire country. In this study, the spatial and temporal dynamics of the riverbank erosion for the largest internal rivers in Serbia (Velika Morava, Zapadna Morava, Juzna Morava, Pek, Mlava, Veliki Timok, Kolubara) was assessed using remote sensing and GIS. The aim of this paper is to determine the total and average soil loss over large-scale periods (1923-2020), comparing data from the available sources (aerial photographs, satellite images, and different scale paper maps). Results indicated that lateral migration caused significant problems through land loss (approximately 2,561 ha), especially arable land, and land use changes in river basins, but also economic loss due to the reduction of agricultural production. Total and average soil loss was calculated for five most representative meanders on all studied rivers, and on the basis of the obtained values, certain regularities about further development and dynamics of riverbank movement are presented. A better understanding of river channel migration in this area will be of a great importance for practical issues such as predicting channel migration rates for river engineering and planning purposes, soil and water management and land use changes, environment protection.

Fra Mauro's world map was created in the middle of the 15th century and at that time it represented a great progress in relation to Ptolemy's geographical and cosmographic representations, which until then had been the starting point for every geographical discourse. This map is one of those epochal works from the era of Humanism and the Renaissance, which illuminated the world with new light and thus moved scientific thought forwards. Fra Mauro's map represented the affirmation of geography and cartography, which at that time had not yet been constituted as sciences, and directed at new geographical discoveries and research. The aim of this paper is to analyse the geographical representations of the Balkan Peninsula on Fra Mauro's map. This paper provides the toponym list of the Balkan Peninsula and some surrounding areas and countries, systematised in its original form and identified in its current meaning. Special attention is given to the identification of the map as a text document, as well as to the explanation of the context, symbolism and contemporary meaning of certain geographical names.

The focus of this study is a spatial analysis of the industry distribution and concentration, on the example of municipality of Tesanj (Bosnia and Herzegovina), based on the application of GIS methods. Municipality of Tesanj is one of the most developed municipalities in Bosnia and Herzegovina, while Tesanj?s industry significantly contributes to the economic development of this country. GIS analysis of industry was based on the field work, locating and georeferencing industrial companies, acquisition, adaptation, adjustment and validation of digital surface models and google satellite imagery, mapping of relief, hydrography and transport network. With the aim of geovisualization of spatial distribution of industry, spatial descriptive statistics and non-parametric density estimation analysis (Kernel Density Estimation) were performed. In order to determine the distribution of industry in relation to relief (elevation, slope, and aspect), hydrography and transport network, GIS techniques of reclassification, vectorization, count point in polygons, buffer and clip geoprocessing tools were used. Conducted research provided a new insight into the data mining and visualization based on principles of QGIS, the effects of geographic factors on industry distribution, and confirmed the importance of relief, hydrographic and transport network on the concentration of industry in municipality Tesanj.

In the Democratic People's Republic of Korea (DPRK), urban planning and urban architecture reflect the interest of the working class. The goal for the working class was to develop a specific type of urban planning, as a result of which the DPRK introduced a socialist model of urban planning. Until the beginning of 1970, the DPRK depended on the influence of the USSR, it wanted to go beyond that framework, especially in the field of urban planning and architecture. In the early 1970s, Kim Il-sung presented the thesis of Juche's idea, which encompasses all aspects of society. During the 1980s, Pyongyang was promoted to the world as the socialist capital of the world. However, in the 21st century, Korean architecture has noticed many changes compared to the past. In addition to remaining faithful to rationality and monumentality, social differences were given to special groups. Since the arrival and rise of Kim Jong-un to power, the newly built parts of Pyongyang are reminiscent of the physiognomy of capitalist cities.

In this paper, the water quality of the Moraca River and its main tributaries (the Zeta and the Cijevna) were analyzed, using the Water Quality Index (WQI) methods. Data from 12 hydrological stations (HS) from 2010 to 2018 were used. The analysis included ten parameters of physic, chemical and microbiological water quality: oxygen saturation, BOD5, ammonium ion, pH value, total nitrogen oxides, orthophosphates, suspended solids, temperature, electrical conductivity and coliform bacteria. Calculations for all 12 HS were made using the Serbian Water Quality Index (SWQI). The results of the research showed that the general situation is not discouraging, because the SWQI values ranged from 73-97, which according to the categorization of water quality corresponds to the classes good, very good and excellent. The only exceptions were the two measuring stations in the lower course of the Moraca River (City Collector and Grbaci). During the entire observed period, the water quality was the worst on the profile of the City Collector (SWQI between 39 and 71) on Moraca River. Also, downstream on Moraca River, on HS Grbavci for 2015, the average annual value of SWQI was 70, which according to the gradation corresponds to the class of poor quality. The biggest sources of pollution were municipal wastewaters, followed by agricultural activities and illegal garbage disposal both along the stream and in the river itself. It follows that the lower part of the Moraca River was the most polluted in the observed basin. This is a serious problem, especially since it is a part of the Moraca River that flows through the most populated and most agriculturally active parts of Montenegro (Podgorica, Zeta Plain, Ljeskopolje). Therefore, it is necessary to take adequate measures as soon as possible, which primarily relate to the introduction of wastewater treatment technology and to educate population about the importance of river water conservation.

Starting from the importance of risk perception for taking certain preventive measures to protect people and their property from disasters, the subject of the research is to examine the factors influencing public perception of mythically-based human behavior in disaster conditions. Using the random sampling method, 250 adult respondents were surveyed in the city of Belgrade, using a specially created and adapted survey questionnaire. The results of the research show that there is no statistically significant influence of gender, age, educational and economic factors on the public perception of human behavior in disaster conditions. The results of the research can be used to improve strategies and campaigns based on risk assessment, aimed at improving the safety of people in disasters.

In this manuscript we analyze daily rainfall observational records from 22 weather stations located in different regions over Serbia in the period 1949-2007. We examine the characteristics of dryness by using the Dry Days Since Last Rain - DDSLR approach. In order to quantify the DDSLR we use three metrics for each weather station: severity, consistency and uncertainty. Results show that these three metrics vary independently of each other as well as that there is a weak relationship between them. Weather stations in the northern parts of Serbia, with moderate annual amount of rainfall less than 650 mm, present higher dryness conditions whereas the lowest values were obtained for central parts in Serbia. Limited number of studies examined drying tendencies in Serbia and neighboring countries so far. We consider Serbia as an area of particular interest because of its position in a frontier between Mediterranean conditions on the southwest and the continental inland.

The Moracke Planine Mountains, situated in the central part of Montenegro, were the center of intensive Pleistocene glaciation. Specific type of moraines - hummocky ones, which have not been recorded in the southeastern Dinarides up to now, were recently identified and investigated in western part of the Moracke Planine Mts. Moraine material accumulated on limestone basement, where several tens of irregularly distributed hummocks and similar number of bowl-shaped dolines have been carved already. The hummocky moraines formed in the glaciokarst landscape where the well-developed karst morphology has been shaped before glaciation. Pre-glacial karst morphology determined the direction of glacier movement as well as its main morphological characteristics (thickness and width). During the most intensive glaciation phase (?IS 12) the Lukavicko-lukovski Glacier, spread out from the central part of mountain towards west, reaching a length of 16.5 km. Due to uneven glacier thickness, the deglaciation process led to its breaking and separation of the lower and shorter part from the rest of the icy mass. Stagnant state of the icy mass led to specific accumulation of moraine material in a form of numerous hummocks, whose melting produced a bowl-shaped dolinas in-between. The paleogeographic significance of hummocky moraines lies in the possibilities of more detailed studies of the Pleistocene glaciers specifics that arise from their evolution in glacio-karst conditions.

Urban meteorological network (UMN) was established in the Central European City of Novi Sad (Serbia) based on "local climate zones" (LCZs) system. Physiologically Equivalent Temperature (PET) index was used for the assessment of outdoor thermal comfort in the "built" and "land cover" LCZ classes of Novi Sad. The index was calculated in the RayMan software based on the meteorological, physiological as well as building and vegetation data. Temporal analysis was performed for extreme heat stress days (PETmax ? 41 ?C), extreme heat stress hours (PETav ? 41 ?C) and days with occurrence of "tropical nights" (Tmin > 20 ?C) during exceptionally hot summer of 2015. Our results show that extreme heat stress hours are the least frequent in compact midrise LCZ 2, followed by dense trees LCZ A. On the contrary, countryside (low plants - LCZ D) showed to be the most uncomfortable area during daytime followed by compact low-rise areas (LCZ 3). Tropical nights are the most frequent in midrise LCZs 5 and 2 (40-46 nights) and decreasing towards open, sparsely built and natural LCZs (6-8 tropical nights in LCZs A and D). This is almost 800% decrease and it has implications for health and recreation of urban population and emphasizes the need for UMN development based on LCZ system.

Physiologically Equivalent Temperature (PET) index was used for the assessment of outdoor thermal comfort in the \"built\" and \"land cover\" LCZ classes of Novi Sad. The index was calculated in the RayMan software based on the meteorological, physiological as well as building and vegetation data. Temporal analysis was performed for extreme heat stress days (PETmax ? 41 ?C), extreme heat stress hours (PETav ? 41 ?C) and days with occurrence of \"tropical nights\" (Tmin > 20 ?C) during exceptionally hot summer of 2015. Our results show that extreme heat stress hours are the least frequent in compact midrise LCZ 2, followed by dense trees LCZ A. On the contrary, countryside (low plants - LCZ D) showed to be the most uncomfortable area during daytime followed by compact low-rise areas (LCZ 3). Tropical nights are the most frequent in midrise LCZs 5 and 2 (40-46 nights) and decreasing towards open, sparsely built and natural LCZs (6-8 tropical nights in LCZs A and D). This is almost 800% decrease and it has implications for health and recreation of urban population and emphasizes the need for UMN development based on LCZ system.","PeriodicalId":35518,"journal":{"name":"Glasnik - Srpskog Geografskog Drustva","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76417728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
