Demographic changes and processes in Negotin municipality settlement network
ivkoviLjiljana,ivkovi? Nenad
Glasnik Srpskog Geografskog Dru?tva , 2006, DOI: 10.2298/gsgd0601105z
Abstract: The analysis of demographic factors of the studied area points to the different demographic development models. Uneven economic and regional development of industry caused the regional demographic polarization of the population of Negotin municipality. In relatively short period, the transition has caused spontaneous urbanization and deagrarization. All that influenced the faster tempo of social and demographic processes, especially the migrations towards Negotin, which led to the developmental unevenness and regional polarization to the zone of population concentration (town and the suburban areas). Contrary to the town center, there are depopulation rural areas, with outstanding economic undevelopment.
About the high flow regime of the rivers of Kosovo and Metohia
ivkovi? Nenad,Gavrilovi? Ljiljana
Glasnik Srpskog Geografskog Dru?tva , 2009, DOI: 10.2298/gsgd0904225z
Abstract: The examples from Kosovo and Metohia attempted to point to some problems in the domain of hydrogeographic regionalization. The river water regime, especially the phase of high flows which marks this regime, has been the topic of almost all researches which treat water resources of drainage basins. However, the thing that has not been achieved till now is the unique solution by which the classification of rivers would be made according to this feature. On this example it has been shown that even some older methods, based on genetic analysis of hydrograms and of global type, as well as some recent ones, with lot of quantitative entry and regional approaches, cannot with certainty answer all the challenges which river regimes bring with themselves. This work shows that apart from climate, orographic and physiognomic features of drainage basins, the periods of data processing and the analysis of individual intra-annual series of discharges are very important as well. Discretization on time periods shorter than one month, as well as elimination of the extreme values of discharges in the longtime series is recommended for the future research.
The role of rural population in agricultural development in the P inja district
Jovanovi? Slavoljub,ivkoviLjiljana
Glasnik Srpskog Geografskog Dru?tva , 2011, DOI: 10.2298/gsgd1101065j
Abstract: Research results presented in this paper refer to changes in the structure of the agricultural population of the P inja District in the period from 1971 to 2002. They point to markedly decrease in the agricultural population, the share of agricultural population in total population, the share of rural population in total population, as well as the share of active agricultural population in total active population. The process of deagrarianization in this area is a constraining factor for the development of agriculture and causes spontaneous abandonment by working-age population who is employing in other sectors. Transfer of agricultural population in non-agricultural activities takes place either by moving into the city centre or by remaining in agricultural households and employing in non-agricultural activities (which causes daily rural-urban migration). The process of depopulation and deruralization caused ageing population to be involved in agriculture in many rural settlements so that the effects of agricultural production have become significantly decreasing. To eliminate the negative effects of the regional development of the P inja District, it is necessary to establish and implement a functional demographic policy and concept of the revitalization of rural area.
Possibilities for the development of ecotourism in protected areas of Western Serbia
Miljkovi? Olgica,ivkoviLjiljana
Journal of the Geographical Institute Jovan Cvijic, SASA , 2012, DOI: 10.2298/ijgi1203065m
Abstract: Sustainable tourism is an important element of modern tourism, which are strictly controlled by the impact of tourism on the environment. Balanced ecological, economic and sociocultural components of tourism are therefore more frequently mentioned in the programs and strategies of tourism development. Sustainable tourism is particularly applicable to the development of tourism in the category of protected natural areas. These natural systems (national parks, nature parks, nature reserves and natural monuments) are all interesting areas for various segments of the tourist. Typically, this is ecotourism - a modern form of tourism in which through education, volunteering, learning about nature, we help protect and preserve nature. Tourism development in protected natural areas is particularly sensitive, and as such it involves the determination of carrying capacity, limits of acceptable changes, environmental impact assessment, tourism zoning and designing codes of ethics that would help tourists to coordinate their activities with the values of the environment.

Thermal regime of Negotinska Krajina
ivkoviLjiljana,ivkovi? Nenad,Jani?-Sirid?anski Marina
Glasnik Srpskog Geografskog Dru?tva , 2005, DOI: 10.2298/gsgd0501039z
Abstract: Negotin Krajina geographically belongs to Mezian tablet that means it is widely open to the influences from the East but main air influences come from the West and North-West causes specific thermal characteristics. Meteorological station "Negotin" is the only one respectable station in the Krajina then we analyze results from various periods since 1901. It is important to emphasize that station "Negotin" doesn't have work continuity since the beginning of the century, thus for analyzing certain climate elements we have had to use method of analogy with station "Zaje ar". A part of that, observations were not done by the same methodology so there is lack of some important indicators for this first period. To determine air thermo-regime of Negotin Krajina during 20 century, standard periods (1901-1930., 1931-1960. and 1961-1990) for analyzing climate elements suggested by WMO, were compared. Also, periods from 1925. to 1940. and from 1990. to 2000. were added to this analysis (according to data we had).
Concept of filter-adsorber type integrated air purifier
Raos Miomir,ivkoviLjiljana,?or?evi? Amelija,ivkovi? Nenad
Facta Universitatis Series : Physics, Chemistry and Technology , 2010, DOI: 10.2298/fupct1001057r
Abstract: In order to prove flow-thermal and operating parameters of air purifiers in a filter-adsorber system, the authors conducted comprehensive experimental examination in the laboratory for air quality control at the Faculty of Occupational Safety in Ni . Experimental examination was carried out on original experimental equipment with the concept of integrated air purifier which includes simultaneous activity of two different filter screens on separating mechanical and chemical test contaminants from a gas mixture. For that purpose, in cooperation with several companies, we designed and produced original filter screens and provided certain conceptual solutions for purifiers. Experimental data were recorded with suitable acquisition equipment in order to identify the processes.
Map as a tool for independent learning in geography teaching
ivkoviLjiljana,Jovanovi? Slavoljub,Ivanovi? Marko
Glasnik Srpskog Geografskog Dru?tva , 2012, DOI: 10.2298/gsgd1203035z
Abstract: There are different views on self-regulation in the learning process, how it has to be monitored, controlled, which are the circumstances and external factors that affect independent learning. Dominant are the opinions in which the self-regulation is treated as interaction of processes related to the personality, behavioural and contextual processes. Special attention has been given to motivational strategies and students’ desire to focus on goals. By enabling students to make decisions, set their own goals, make a choice, plan and organize activities, the development of self-learning and student autonomy is being encouraged. If students are given the opportunity of independent activities, effect of self-control in the process of learning and self-regulation becomes more pronounced. The paper will explain the factors that influence the process of self-learning that takes place in regular teaching with the help of map as the basic geographic media.

Functional connection of didactical elements in teaching geography
ivkoviLjiljana,Jovanovi? Slavoljub,Ivanovi? Marko
Glasnik Srpskog Geografskog Dru?tva , 2010, DOI: 10.2298/gsgd1002247z
Abstract: The aim of this work is to present complex relations within didactical triangle as well as review of the practical usage of relations of didactical polygon. Importance of subject of this work is, certainly, its constant actualization and irrepressible change which is happening within elements and in their mutual interaction. This kind of relation brings innovations and suffers changes from modern times. Starting from immediate ways of communication to closer and further perceive of their development, the subject gets dimension of expected and somewhat exciting. The theme ensued because of the need for logical separation of didactical elements and also to connect them through complex system of communication. Their imbues are coming to express daily while interaction is developing not only in historical period but in instantaneous stages. The media, today, gives grade to development of society and represent degree of progress. As such an important factor, the role of the media must be taken into consideration. Geographical achievement is represented by teaching methods of geography and in that way it represents significant media. Complicatedness of this theme also reflects in universality; geography has advanced as science and there is great expectation for methodical science to catch up with geography and to present new manners, ways of transferring knowledge. .
Contents on the environmental protection in the geography textbooks for primary and secondary schools
Jovanovi? Slavoljub,ivkoviLjiljana,An?elkovi? Sla?ana
Glasnik Srpskog Geografskog Dru?tva , 2010, DOI: 10.2298/gsgd1001347j
Abstract: The paper analysis the contents of Geography textbooks which refer to the problems of the protection of the environment. The last publications of Geography textbooks for primary and secondary schools of the Zavod za ud benike i nastavna sredstva (Belgrade) were used as a sample. With this study we wanted to check at what extent the contents of the environmental protection are present in the contemporary Geography textbooks and how much they contribute to the formation of the system of ecologic knowledge and ecologic conscience of students with their structure. The analysis has showed that the problems of the environmental protection in the analyzed textbooks are not present enough, that they are mostly covered in integrative way, sporadically and declaratively. Undefined ecologic concepts are twice as much presented as defined. The explanations of notions are more often supported by examples than by factographic data, although the number of examples is insufficient. Especially, the examples from close surroundings are missing. With their structure, the present contents do not provide knowledge on numerous problems on the protection of the environment and they do not influence the development of ecologic attitudes, emotions and habits in students. Practical implications of the study are shown in the way that the results and conclusions can stimulate the authors of textbooks to change the approach in planning the contents of the future Geography textbooks... .
Theoretical framework of individual learning process in geography tuitition in elementary school
Jovanovi? Slavoljub,Jani?-Sirid?anski Marina,ivkoviLjiljana
Glasnik Srpskog Geografskog Dru?tva , 2005, DOI: 10.2298/gsgd0501291j
Abstract: Individual learning is the process that pupils use their own activities (intellectual and practical). The school primarily has to develop pupils' skills and habits for individual learning, i.e. to enable them for active learning using their own capacities. This program has to be applied in the earlier stages to produce growth of children's autonomy and independence in coming stages. Individual learning, above all, demands flexibility of thoughts, critic opinion, individual work and intellectual independence creativity, motivation and interest and pupils' participation during the tuitition.
