A GIS-based method for analysis of a better utilization of thermal-mineral springs in the municipality of Kursumlija (Serbia)
No full textThere are about 240 geothermal occurrences with 60 commercial spas included in, which are spread throughout the territory of Serbia. The majority of springs and other surface manifestations are located along the southeastern edge of the country. Three spas Lukovska, Prolom and Kursumlijska are with the highest geothermal potential and balneology utilization. They are situated in the vicinity of Kursumlija, one of the largest municipalities in Serbia, but with poor economic development. Although the presence of these three spas and more than 23 thermal mineral springs with the temperature of water between 26.4 degrees and 68 degrees C reveal it among the great geothermal resources in Serbia, the extent and potential of these resources are poorly understood. The estimated capacity of geothermal energy in three spas and 20 springs is 620.36 (TJ/year) or 19.6 MWt. In spite of a vast quantity of this clean, renewable energy resource only a small percentage of it is used in balneology and extremely rarely for greenhouse heating. In Serbia the kind of energy mostly used belongs to dirty energy resources, such as timber, coal, oil, gas, natural gas, etc. The use of geothermal renewable energy for the heating of public institutions is highly recommendable and agrees with today's growing awareness of the environment protection and improvement of the quality of life. The additional use of it for heating in householders would reduce the import of natural gas and oil and would support the municipality and its inhabitants to escape from poverty
Comparative analysis of NDVI index and different satellite images classifications in determination the vegetation inventory of Vrčin settlement
Get PDFThe modern way of life has affected the extremely high level of environmental degradation. Modern technologies, on the one hand, degrade our environment, but on the other they can also be used to preserve and improve its quality. An efficient monitoring system is able to monitor the status and changes in the vegetation cover of a particular area. In this paper will be shown the determination of the vegetation inventory of the settlement Vrčin through the NDVI (Normalized Difference Vegetation Index) and comparison of the data thus obtained with the various available classifications of satellite images, in order to determine the best monitoring system in the environment through remote detection
The evaluation of geosites in the territory of National Park "Kopaonik"(Serbia)
Get PDFIn the relatively small area of the National Park (NP) "Kopaonik" a lot of exogenous and endogenous processes took part and continue to act until present day. In this paper are presented the geotouristic resources evaluation results for six geosites in the NP "Kopaonik". The experts on this field gave their assessment in three versions. The first one is concerned with the evaluation of the educative contents, the second one is concerned with the evaluation of geotouristic values, while the third version, which is based on the Modified Geosite Assessment Model (MGAM) offers the assessment regarding education, aesthetic significance, protection, functional and touristic values. The M-GAM method takes in consideration the opinion of visitors along with the estimation of subindicators given by experts, on whom relies the previous two versions. The include of visitors in the evaluation process leads to more objective estimations. Results obtained by this study can be useful for the improvement and planning of touristic activities on geosites because, bearing in mind their significance for the tourists, they indicate on the lower values that require more attention in the future
The assessment of aridity in Leskovac basin, Serbia (1981-2010)
Get PDFIn the paper, the aridity is defined on the basis of four climate indices: De Martonne's index of aridity, Lang's Rain Factor and Gracanin's Rain factor for the vegetation period and hydrothermal coefficient of Seljaninov. While the annual value of the drought index (I-DM) shows humid characteristics, the monthly values show the variability of the conditions. The summer months (July and August) are classified as semi-arid months, while the winter months (December-February) are extremely humid. The spatial distribution of the isoarids indicates that the northern part of the basin has the characteristics of a semiarid climate, while the southeastern parts are more humid. The analysis of mean annual values of the drought index indicates in semiarid conditions (1990 and 2000), but also the humid conditions (2005 and 2009). A positive linear trend indicates that there is a tendency towards humid conditions. The significance test confirms the existence of a statistically significant trend. During the vegetation period, semi-arid conditions are present (July-August). April is slightly humid, and October is moderately arid. The Lang's Rain Factor (KFg) characterizes basin climate as semiarid, while the Gracanin rain factor for the vegetation period (KFm) indicates a moisture deficit in the summer months. Hydrothermal coefficient Seljaninova (HTC) indicates a lack of moisture in July and August. Vegetation period is characterized as insufficiently humid. Irrigation is one of the most important measures for solving drought problems, since the yield varies from year to year
Istraživanje kognitivnih i afektivnih komponenti destinacijskog imidža Beograda
Get PDFBelgrade is the most popular tourist destination in Serbia, whose tourism industry is rapidly recovering from the turbulent events of the 1990s. However, Belgrade's destination managers yet need to use to a greater extent its competitive advantages which would improve the city's ability to compete with more prominent cities in the international market. These managerial efforts should be based on relevant image assessments. The aim of this research is to offer a comprehensive insight into Belgrade's destination image by combining quantitative and qualitative data collection methods in order to identify the crucial components of its cognitive and affective images. Additionally, this study examines the influence of various tourists' socio-demographic characteristics on their perceptions of destination image, providing both theoretical and marketing implications. Cultural attractions, nightlife, gastronomy and history were identified in the qualitative study as the most important elements of Belgrade's cognitive image, while the most common affective associations were related to it being vibrant, authentic and relaxing. In the quantitative study, six factors of Belgrade's cognitive image were identified-Tourist Attractions, Services and Fun, Environment, Accessibility, Local Residents, and River Banks and Green Areas. Regarding the affective component, it was established that Belgrade was primarily perceived as pleasant, but also as exciting, cheerful and relaxing. Hypotheses testing indicated that tourists' affective responses towards Belgrade varied in relation to their gender and geographical origin, while some of their cognitive perceptions differed in relation to their gender, age, education and employment.Beograd je najpopularnija turistička destinacija u Srbiji, čija se turistička privreda ubrzano oporavlja od turbulentnih događaja iz 1990-ih. Ipak, destinacijski menadžeri Beograda tek treba da u većoj meri iskoriste komparativne prednosti grada, što bi poboljšalo njegovu sposobnost da se takmiči sa već afirmisanim gradovima na međunarodnom tržištu. Ovi upravljački napori treba da budi zasnovani na relevantnim procenama imidža. Cilj ovog istraživanja je pružanje sveobuhvatnog uvida u destinacijski imidž Beograda kombinacijom kvantitativnih i kvalitativnih metoda prikupljanja podataka, a u cilju identifikacije ključnih komponenti njegovog kognitivnog i afektivnog imidža. Pored toga, ova studija ispituje uticaj različitih socio-demografskih odlika turista na njihove percepcije destinacijskog imidža, što pruža teorijske i marketinške implikacije. Kulturne atrakcije, noćni život, gastronomija i istorija su identifikovani u kvalitativnoj studiji kao najvažniji elementi kognitivnog imidža Beograda, dok su najčešće afektivne asocijacije povezane sa time da je grad živahan, autentičan i opuštajući. U kvantitativnoj studiji, identifikovano je šest faktora kognitivnog imidža Beograda – Turističke atrakcije, Usluge i provod, Okruženje, Dostupnost, Lokalno stanovništvo i Obale reka i zelene površine. Kada je afektivna komponenta u pitanju, utvrđeno je da se Beograd prvenstveno percipira kao prijatan, ali i kao uzbudljiv, radostan i opuštajući. Testiranje hipoteza pokazalo je da se afektivne reakcije turista prema Beogradu razlikuju u zavisnosti od njihovog pola i geografskog porekla, dok neke od njihovih kognitivnih percepcija variraju u zavisnosti od njihovog pola, uzrasta, obrazovanja i zaposlenosti

Deca migranti u školama u Srbiji - barijera ili izazov za novi početak
Get PDFThe inclusion of migrant children into the formal education system of the Republic of Serbia represents a long-term project implemented by the Ministry of Education, Science and Technological Development with the support of international organizations and civil society organizations. Te education system of the Republic of Serbia in terms of their education faces two key challenges. The first challenge is that they are in transit through Serbia and the length of their stay unpredictable. Another challenge relates to the comprehensive approach and commitment system as a whole. Consequently, the subject of this paper is to identify the legal and institutional framework for the inclusion of migrant children into the formal education system, as well as the analysis of the situation in practice. the aim is to test the implementation of the previous model for the inclusion of migrant children into the formal education system of the Republic of Serbia. the aim of the work is concretized through specific that include the organization and realization of teaching in schools in combined classes of students, but also in the context of reception centers, as well as support to students through additional work after implementation in primary school. By examining the attitudes of all participants involved in the educational process (migrant children, teachers, school director and professional associates) contribute to reducing prejudice and stereotypes about migrant children, as well as the exercise of their rights in the education system. the applied methodology, which included surveys and semi-structured interviews, obtained the guidelines for the effective implementation of the existing normative framework aimed at successful integration of migrant children into society. the results suggest that migrant children in educational institutions acquire functional knowledge and skills in order to adapt to the new environment, socialization, stress relief, a sense of security and freedom.Uključivanje dece migranata u formalni obrazovni sistem Republike Srbije predstavlja dugoročan projekat koji sprovodi Ministarstvo prosvete, nauke i tehnološkog razvoja uz podršku međunarodnih organizacija i organizacija civilnog društva. Obrazovni sistem Republike Srbije se po pitanju njihovog obrazovanja suočava sa dva ključna izazova. Prvi izazov je što se oni nalaze u tranzitu kroz Srbiju te je dužina njihovog boravka nepredvidiva. Drugi izazov se odnosi na sveobuhvatni pristup i angažovanje sistema u celini. Shodno tome, predmet ovog rada jeste identifikacija zakonodavnog i institucionalnog okvira za uključivanje dece migranata u formalni obrazovni sistem, kao i analiza stanja u praksi. Cilj rada je testiranje primene dosadašnjeg modela za uključivanje dece migranata u formalni obrazovni sistem Republike Srbije. Opšti cilj rada je konkretizovan kroz specifične koji obuhvataju način organizacije i realizacije nastave u školama u kombinovanim odeljenjima učenika, ali i u okviru prihvatnih centara, kao i podršku učenicima kroz dopunski rad nakon uključivanja u osnovnu školu. Ispitivanjem stavova svih aktera uključenih u obrazovno-vaspitni proces (dece migranata, nastavnika, direktora škola i stručnih saradnika) može se doprineti smanjivanju predrasuda i stereotipa o deci migrantima, kao i efikasnijem ostvarivanju njihovog prava u sistemu obrazovanja. Primenjenom metodologijom, koja je obuhvatila anketna istraživanja i polustrukturisane intervjue, dobijene su smernice za efikasniju implementaciju postojećih normativnih okvira koji imaju za cilj uspešniju integraciju dece migranata u društvo. Rezultati istraživanja ukazuju da deca migranti u obrazovno-vaspitnim ustanovama stiču funkcionalno znanje i veštine u cilju adaptacije na novu sredinu, socijalizacije, oslobađanja od stresa, osećaja sigurnosti i slobode
Spatial behaviour of tourists in Belgrade
Get PDFFor the purpose of destination planning, management and marketing it is imperative to understand the patterns of tourist spatial activities within cities; in the sense of delineating of tourist zones and major pathways, prognosis of the time spent at particular locations and realizing factors which shape the movement of tourists. The aim of this research is to outline the areas intensively used by tourists during their stay in Belgrade and to analyse the influence of various factors on their spatial behaviour. To collect relevant data, 325 foreign individual tourists were interviewed with the aim of collecting data regarding their spatial activities, visit specifics and socio-demographic characteristics. Independent t-test and one way variance analysis (ANOVA) procedures were conducted in order to explore statistically signifi cant differences in spatial behaviour of tourists based on their socio-demographic and visit characteristics. The study confirmed the importance of Belgrade's historical area for tourism and identifi ed various factors regarding internal characteristics of their visit to the influences characterizing spatial behaviour of tourists in Belgrade. The results can be used to create long-term strategies that would promote a polycentric and balanced distribution of tourist activities across Belgrade and in turn prevent negative effects on the city life itself
Calpionellid biostratigraphy and microfacies of the Upper Tithonian pelagic carbonates in northeastern Serbia (Carpatho-Balkanides)
Get PDFThe occurrence of microfossil assemblage represented by calpionellids in close association with benthic foraminifera and encrusting Crescentiella morronensis is reported for the first time from the Upper Tithonian of NE Serbia. The biostratigraphic and sedimentological investigations were carried out on a 250 m thick carbonate succession in Jelenska Stena quarry cropping out along the Danube River Gorge in the border area of Serbian Carpatho-Balkanides and Romanian Southern Carphatians. On the basis of determined benthic foraminiferal taxa Textularia sp. cf. T bettenstaedti and Everticyclammina praekelleri in the lower part of the succession and calpionellid association dominated by the representatives of calpionellid genera Tintinnopsella, Crassicollaria and Calpionella the carbonate succession is assigned to the Upper Tithonian. The scarcity of calpionellid zonal species prevents the nominal zones being recognized. Petrographic analysis of thin-sections led to the recognition of three basin microfacies types: bioclastic wackestone, bioclastic peloidal wackestone/packstone and mudstone. These microfacies characterize the SMF 3 and SMF 4 which indicate deposition in slope and toe-of-slope environments. This study extends the palaeogeographical distribution of Upper Tithonian calpionellids along the northern Tethyan margins. The investigated carbonate succession is compared with coeval strata from other northern Tethyan regions
Промена парадигме о демографском старењу
Get PDFСтарење становништва је доминантан демограсфки процес који трансформише друштво и отвара алармантна питања економске и социјалне одрживости. У проналажњу решења за бројне импликације пораста старог становништва, креирана је парадигма активног старења. За разлику од претходне, која се базирала на стереотипима и била окренута ка збрињавању и нези остарелих, нова се фокусира на потенцијале, а не ограничења старијих. Концепт активног старења још није праћен кохерентним политикама, упркос акционом плану међународне заједнице. У критичким освртима на његову реализацију у пракси, уочава се пут од слогана ка ефикасној мери за успостављање друштва за све генерације. Током концептуализације нове парадигме уочене су замке неадекватних интерпретација и могућности нових видова искључености старих, па су неопходна правила тумачења концепта и изградња хуманог друштва, као гаранције његове успешне имплементације. Промена прадигме иницирана је убрзаним темпом и интензитетом старења, а базирана је на редефинисању старости, уочавању генерацијске хетерогености и различитих стилова живота сениора. Активно старење је омогућило афирмацију старог становништва и обликовало транзициону параболу њиховог друштвеног статуса. Демографски подаци показују да је најстарији континент Европа, а Србија у групи демографски најстаријих земаља, те се питање формулисања политике активног старења у нашој земљи актуелизује.Уредници: Владимир С.
