CLIMATE REGIONALIZATION OF SERBIA ACCORDING TO KÖPPEN CLIMATE CLASSIFICATION
Get PDFThe paper presents a concise overview of the theoretical framework on which climate classifications are based. Beside short review of climate classifications, namely climatic regionalization for Serbia (or wider area including Serbia), main deficiency of these research was ascertained (which primarily relate to the period on the basis of which climate regionalization was carried out). The criteria of the Köppen climate classification are presented, on the basis of which the climate regionalization of Serbia has been carried out. The methodology of making maps of air temperatures and precipitation amounts has been described, on the basis of which a map of the climate regions of Serbia has been created. Spatial distribution of the types and subtypes of the climates in Serbia has been briefly described. It has been pointed to the constraints of the climate regionalization that arise from the theoretical bases of the climate classifications, but also from nature of the collected data and the applied methodology
THE EFFECTS OF SOLAR ACTIVITY: ELECTRONS IN THE TERRESTRIAL LOWER IONOSPHERE
Get PDFSolar flare X-ray energy can cause strong enhancements of the electron density in the Earth’s atmosphere. This intense solar radiation and activity can cause sudden ionospheric disturbances (SIDs) and further create ground telecommunication interferences, blackouts as well as some natural disasters and caused considerable material damage. The focus of this contribution is on the study of these changes induced by solar X-ray flares using narrowband Very Low Frequency (VLF, 3–30 kHz) and Low Frequency (LF, 30–300 kHz) radio signal analysis. The model computation and simulation were applied to acquire the electron density enhancement induced by intense solar radiation. The obtained results confirmed the successful use of applied technique for detecting space weather phenomena such as solar explosive events as well for describing and modeling the ionospheric electron density which are important as the part of electric terrestrial-conductor environment through which external-solar wind (SW) electrons can pass and cause natural disasters on the ground like fires
SOME ASPECTS OF THE REGIONAL COOPERATION IN THE BALKANS
Get PDFSince the beginning of the 21st century, the political role of the state borders in the Balkans has changed. Gradually they began to transform from barriers into zones of bilateral and multilateral cooperation. The common European integration includes the creation and development of Euro-regions. Within the context of reorganization of the new European space, geopolitical importance of South-East Europe has significantly upgraded. This fact reflects on the interests of the international community in security and development of this region. Despite that the Balkans constitute an indispensable part of the European continent, their incorporation into the new European architecture has been particularly difficult and problematic. They emerge as the most volatile and least integrated European region. There are significant variations among the countries concerning their territory, number of population, as well as the rate of the economic changes. The main forms of regional cooperation should be concentrated on the domains of transport, energy and communication infrastructure, trade and economic cooperation, environment and security. From this point of view, the economic growth and increase of living standard are the most important problems for all Balkan countries
TOURISMOLOGICAL CLASSIFICATION OF SPORTING EVENTS
Get PDFSporting events are programs, which are dominated by creative and complex facilities, primarily sports, but also recreation and entertainment. As such, they achieve tourism effects and goals and have a socio-economic importance for the city, region or state. Depending on the size and importance of sports event, sport has a different role in the context of promoting tourist destination, as well as different values. Each sport discipline has its own criteria by which athletes are ranked individually or as team. The subject of the research is to determine the criteria for the categorization of sporting events, in order to determine the importance of sporting events as an element of the tourist offer (individually or as part of a tourist destination). Also, this paper’s results present a comparative analysis of similar methodologies for the categorization of sporting events. Based on the research presented in the paper, there are four groups of criteria: economic, media, social and environmental. Together with this, paper gives the classification of traditional sporting events in the case of Serbia, dividing them in four groups
THE EXAMINATION OF THE RESIDENTS’ ACTIVITIES AND DEDICATION TO THE LOCAL COMMUNITY — AN AGRITOURISM ACCESS TO THE SUBJECT
Get PDFThe paper deals with conceptual guidelines, basic aspects and spatial frameworks of the development of agritourism. The holistic approach, in this regard, includes the integrated and the comprehensive aspects of tourist stays in the countryside. The authors define the impact of agritourism on rural surroundings and analyze the influence of spending leisure time outside urban areas and consuming agritourism activities. Understanding the many components of agritourism is essential for future planning, management, business decisions and strategies. For success in agritourism, knowledge is necessary in many economic fields, including organization, management and marketing, among others. In addition, this article emphasizes products and services in agritourism and provides insight into the facilities and opportunities that are offered to tourists in rural areas. The research findings represent a useful tool for obtaining information about many elements of agritourism development and can serve as a relevant instrument in travel industry research or in academic investigation
ANALYSIS OF TOURIST MOTIFS IN THE FUNCTION OF DEVELOPMENT OF CULTURAL TOURISM IN THE SETTLEMENTS SURROUNDED BY PROTECTED NATURAL RESOURCES
Get PDFThe paper deals with the presence of anthropogenic tourist motifs in the area of the Special Nature Reserve “Carska bara” in the north of Serbia with the following rural settlements taken into consideration: Belo Blato, Ečka, Knićanin, Lukino Selo, Perlez and Stajićevo. The presence of cultural heritage from a group of archaeological sites, works of monumental and artistic features, spatial cultural and historical units, famous places and memorials, folklore heritage, religion and beliefs, language and manifestation values has been recorded in the studied area. The area is well connected with the city centers of this part of Serbia and for the current level of tourism development, it has a satisfactory number of accommodation capacities. After analyzing literature and local cultural offer, it is concluded that for the purpose of attracting more tourists, cultural, that is anthropogenic tourist motifs must be united in the offer with the natural phenomenon Carska bara and its near environment. Together, they can lead to the development of an increasingly popular type of cultural tourism — creative tourism, enchanting tourists the life of the local population, their culture and customs
DETERMINATION OF WATER RESOURCES IN RIVERS IN THE BULGARIAN BASINS OF THE LOWER DANUBE
Get PDFObject of the study is surface water bodies from category “rivers” according to Water Framework Directive 2000/60/ЕС. Surface water assessment is important for number of activities such as: water management in the country, making reports to international agencies, determining the change of the resources in the light of upcoming climate changes. The determination of water resources is based on information of hydrometric stations from the monitoring network system in the National Institute of Meteorology and Hydrology — Bulgarian Academy of Sciences (NIMH-BAS) in which real ongoing and available water flows that are subject of management are registered. In the study a technology for surface water bodies in the Bulgarian basins of the lower Danube is applied which has been developed in the frame of cooperative project together with the Ministry of Environment and Water. This is absolutely true for the Bulgarian section of the Danube River basin which is expressed in big number and variety of hydrological homogeneous sections. The river flow is characterized with annual and inter-annual variability determined by climatic factors and anthropogenic influences. The main obtained results of the present hydrologic studies are the usage of transferred information from gauged to ungauged watersheds and the estimation of the surface water bodies’ resources using original regression relationships based on multiannual hydrological information from the NIMH-BAS monitoring network. The relationships delineate the hydrological homogeneous areas with similar conditions of flow formation. The estimated resources have significant usefulness for all State institutions managing the water in the Danube basin and have already been introduced in the operative and management practice
THE EVALUATION OF THE ROLE OF TEACHING AIDS IN STIMULATING PUPILS’ ACTIVATION IN GEOGRAPHY
Get PDFThis paper discusses the methodological procedures of application of teaching aids through the subjects: World around us, Nature and Society and Geography, as well as an adequate choice of teaching resources that encourage students to earn a permanent knowledge. The idea is to use teaching aids in active teaching and to turn it into the practical use of the material, in order to efficiently adopt the fundamental knowledge about the nature of science in the classroom teaching. The procedures are identified, which are especially important from the point of maximum achievements in teaching the use of teaching aids, and especially significant for subjects the World around us, Nature and Society and Geography. The aim of this study was to determine the importance of teaching aids in active teaching, as well as whether the student becomes mentally active participant in the educational process using teaching aids. The study involved class teachers (154) who evaluated the importance of teaching resources for permanent adoption of knowledge of students. In addition, the survey was analyzed and different types of learning resources in terms of their values in the activation of thinking in students were analyzed as well. This survey has confirmed the hypothesis about the importance of teaching aids for thoughtful activation of the students
ELECTRONS OR PROTONS: WHAT IS THE CAUSE OF FOREST FIRES IN WESTERN EUROPE ON JUNE 18, 2017?
Get PDFForest fires in Portugal (June 17–24, 2017) destroyed 64 lives and caused considerable material damage. The coronal hole CH807 and the energy region S5710 were in the geoeffective position on the Sun immediately before the outbreak of fires. In the period that preceded it, as well as at the time of the fires, increased values of the solar wind (SW) parameters (temperature, speed and density of particles) were recorded. In addition, a geomagnetic disorder was recorded. The shape and size of the burning areas, as well as the low air pressure over Portugal indicate the possibility of the effect of positively charged particles that came from the area south, i.e. southwest of Portugal. Nevertheless, it is a specific case that would have to be investigated in more detail
DOES SMALL TOWN WITH TOURISTIC FUNCTION HAVE DEMOGRAPHIC POTENTIAL?
Get PDFThis research is conducted to determine impacts of tourism development on the demographic image of selected small towns in Serbia. Analyzing the following indicators – tourism potential, the share of inhabitants employed in the tourism industry, tourist turnover, and tradition in tourism, the group of 23 small towns is singled out. Further, the selected small towns with dominant tourism function are observed within four tourism clusters. Demographic characteristics of these urban settlements are analyzed through population indicators: total population increase/decrease, age and sex structure, economic activity, education structure, etc., according to the latest available data. The level of local population involvement in tourism is examined, as well as the influence of these small towns on the immediate rural surroundings. The results of conducted analysis show that tourism has an important impact on demographic development in several observed small towns. In the case of other selected small towns, the tourism influence on population increase or migration is stagnating. Despite that, increasing number of employed in the tourism industry is recorded, which implies that tourism is recognized within local community as an activity that could contribute to the development of small towns in Serbia.
