Abstract: The analysis of the relevant literature, especially earlier empirical research of serious pandemics (not including the forces of nature and the processes they create), refers to the assumption that man is (directly or indirectly) guilty of them. Given that the media transmits information related to the intensity of the spread of the pandemic, the death rate of the sick, etc., a survey of citizens’ trust in the local media and the information they convey was conducted in order to find out how much the media contribute to the intensity of the spread of the negative effects of the Covid 19 pandemic. Four assumptions were defined as questions to which respondents’ answers were requested: frequency of information through different types of media; assessment of the extent to which different types of media offer the possibility of objective information; the existence of free, independent and impartial media in Serbia, and finding the truth in the media. The research is of a quantitative type, conducted on a sample of 600 respondents in the city of Belgrade. For the collection and processing of data used the desk method, using interviews and via electronic questionnaires, in which the questions in the first part related to the socio-demographic variables of the respondents, while in the second part the group of dependent variables was operationalized through the statements, which were evaluated on a Likert scale. More sub-questions are offered within the four main questions. Descriptive statistical analysis (percentages, arithmetic mean), T-test, One-factor analysis of variance, Standard deviation, Multiple regression analysis and Pearson’s correlation coefficient were used for data analysis. The level of statistical significance was set at p<0.05, and all obtained data were processed in the SPSS program, version 23.
Abstract: The paper addresses the issue of the state border. It emphasizes the fact that the state border is a multi-component and multifunctional phenomenon. It was proved that a legally established and internationally recognized border acquires a sign of politicality. The political boundary is a holistic and dynamic phenomenon, inherent in the internal logic of development. The issues of functioning and institutional support of state borders were generalized. The influence of state borders on the development of border territories was revealed. A scheme for the development and integration of contact border areas has been developed. The factors of contact border regions development were studied, as well as the process of various types of regional socio-economic systems formation under the condition of the predominance of state border certain functions. The importance of the functioning of state borders and the development of border regions for the formation of various types of ties, the level of stability of the border and the formation of a political environment have been clarified.
Abstract: This paper aim to investigate the possibility of permafrost occurrence in the alpine area of Rodna Mountains by describing the rock glaciers distribution and characteristics and by monitoring the ground surface temperature and spring water temperature during late summer. Rock glaciers have a rather scarce distribution between 1670 and 1960 m a.s.l., their morphology is completely relict even at the highest altitudes which indicate they are inherited landforms. Thermal regime indicates improbable permafrost at Bila talus slope (1844 m a.s.l.) and an ambiguous outcome at Curmătura Buhăescului talus slope (1980 m a.s.l.) where average temperature during the BTS period was warmer than the -2°C threshold only in one year of the two monitored. Alpine spring water temperatures are above 3°C indicating absence of permafrost and they are moderately correlated with altitude. Iezeru Pietrosu cirque headwall is affected only by seasonal frost at 2100 m a.s.l. for almost 9 months. It seems that in Rodna Mountains the past and present climate conditions were and are milder in comparison to Southern Carpathians as the latitude increase does not compensate the lower altitudes.
Abstract: The paper characterizes thermal and humidity conditions within one of the insufficiently investigated parts of Bulgaria from the climate point of view, namely the south-western slope of the Pirin Mountains. The initial data for the study (monthly temperatures and precipitation amounts) were obtained from our own meteorological monitoring station for the period 2013-2021, organized by the Department of Climatology, Hydrology and Geomorphology, Sofia University, Bulgaria. By the calculation of Mayr tetratherm (MT), monthly De Martonne aridity index (Im) and Compensated Summer Ombrothermic index (CSOi) the predominance of humid conditions in the studied area is established. There is a large inter-annual variability of the De Martonne aridity index and the Compensated Summer Ombrothermic index, which are more influenced by precipitation than air temperature in the middle part of the mountains. On the other hand, in combination with low precipitation amounts, high temperatures in recent years have contributed to the manifestation of arid features of the climate. The results of the study supplement the insufficient information about the bioclimatic characteristics of the Pirin Mountains and clarify the peculiarities of the climate in these mountains, which have two clearly distinguishable macroslopes with west-southwest and east-northeast exposure.
Abstract: Role of Green Open Space (GOS) is essential in creating a comfortable environment in cities. It is detected using a high-resolution satellite image, Planetscope-3A. This study aimed to classify landcover in Banda Aceh using a multispectral classification of Planetscope-3A image and to assess the applicability of Planetscope-3A image to identify GOS in Banda Aceh. The multispectral classification was used with a supervised classification-maximum likelihood algorithm that refers to normalized difference vegetation index (NDVI) transformation to obtain eight landcover classes. Additionally, field observation was used to retrieve sample points determined by Stratified Random Sampling. The classification detected eight landcover classes comprising non-GOS objects (water, developed, barren) and GOS objects (trees, shrubland, herbaceous, wetland, and cultivated). The result was combined with 128 samples data of field, producing an accuracy of 76.036 % and a kappa value of 0.726. Landcover was dominated by developed class with 29.739 km2 or 53.6 % of study area total with an accuracy of 94.094 %. Furthermore, GOS in Banda Aceh included 19.589 km2 or 35.291 % of the study area, consisting of trees (6.863 km2, accuracy 79.396 %), Shrubland (8.216 km2, accuracy 59.413 %), Herbaceous (4.132 km2, accuracy 73.564 %), Cultivated (0.291 km2, accuracy 73.475 %), and Wetlands (0.088 km2, accuracy 70.185 %). This concludes that Banda Aceh has a sufficient area of GOS. The result of GOS detection using Planetscope-3A image with supervised classification-maximum likelihood algorithm could be reference data and recommendation in managing sustainable development in Banda Aceh.
