The hunting tourism product is based on various hunting game and other types of services (accommodation, food, transport, educational services, cultural and recreational activities). This study reveals four factors that influence choosing a hunting destination and satisfaction with consuming tourism services. The study aimed to analyze the relationship between hunting tourism products quality and overall tourist satisfaction and to examine the measurement model for hunting tourists’ satisfaction. This scale focuses on specific elements of hunting tourism products and contributes to a better understanding of the quality of hunting tourism offers. Using the CFA, the reliability and validity of the hunting tourism satisfaction scale (HUNTSS) were confirmed on the sample in Serbia, and this scale was validated as a reliable four-factor model which could be assessed for future research improvements. Results of SEM showed the influences of four factors of hunting tourism products on overall satisfaction.

Examination of radioactivity in edible liquids is very important because large amounts are taken into the body during the day. This scientific paper presents a comprehensive study on the gamma spectrometry analysis and health risk assessment of edible liquids. The study involved samples of various liquid products such as alcoholic beverages, juices, and milk. Milk is an important part of our regular diet for everyone, from newborns to adults, so we determined the active concentrations of radionuclides for both milk from farms directly and milk bought in a supermarket. The gamma spectrometry analysis was performed using a high-purity germanium detector to determine the concentration of natural and artificial radionuclides. The radioactivity of each sample is presented as the mean value of the measured sample from five different manufacturers. In conclusion, the gamma spectrometry analysis and health risk assessment of edible liquids demonstrated that the concentration of radionuclides in the selected liquid food products was not a major health concern. However, continuous monitoring and evaluation are recommended to ensure that the safety of the products is maintained within the permissible limits.

As mobile phones have become a necessity in modern society, and there is an increasing number of users of various ages, it is imperative to investigate the impact of mobile phone radiofrequency electromagnetic radiation (RF) on humans. Because the human head is one of the most exposed and sensitive organs in the body, this paper investigated the propagation of the electromagnetic (EM) field through it. Additionally, the Specific absorption rate (SAR) was examined to study how RF radiation affects the human head. A program code using the finite-difference time-domain (FDTD) method was created to simulate the propagation of RF radiation through the six layers that make up the human head (skin, fat, bone, dura mater, CSF, and brain). RF radiation at the following frequencies was investigated: 0.9 GHz, 1.8 GHz, 2.4 GHz, 3.35 GHz, and 4.5 GHz. Values of the thickness and parameters of the layers can also be changed in the program. It was discovered that the majority of the EM energy is absorbed in the skin of the human head.

Successful development of hunting tourism requires the support of a local community and positive attitudes of residents. This research aims to explore the population in the Vojvodina region (Serbia) which was well known hunting tourism destination in Europe during the '70s and '80s. The survey included a final sample of 206 respondents. This study showed that residents mostly approve of and support hunting tourism revitalization. However, they find that it needs to be implemented sustainably, according to the law, without threatening the habitat and game funds. This study also explored different predictors that shape attitudes towards hunting tourism. Results show that being a hunter, having a higher level of education, frequently having outdoor activities in nature, being interested in the topic of hunting and hunting tourism, and having a dominant meat diet lead to a more positive attitude towards hunting tourism.

The temporomandibular joint (TMJ) represents a biomechanically and morphologically complex structure, tightly connected with the development and growth of mandible and craniofacial complex. The aim of this article is to comprehensively present contemporary diagnostic modalities and clinical implications for imaging of the TMJ. Contemporary imaging modalities, if used properly and according to adequate clinical implications and criteria, are able to depict different pathological processes and play a crucial role in establishing the right diagnosis and monitoring therapeutic effect. The key to right diagnosis, however, still lies in good knowledge of the TMJ developmental and functional anatomy, as well as the TMJ dysfunction related to the jaws, surrounding muscles, teeth, and cranial base.

Deforestation could influence land cover ecological significance in hunting grounds on a big scale. This research examines changes of forest and shrub patches in the Vojvodina region by a set of landscape metrics. The study area includes 154 hunting grounds from which hunting organizations are managing with 134 hunting grounds, PC "Vojvodinasume" with 17, Serbian Armed Forces with two, and National Park "Fruska gora" with one hunting ground. The results show that in the National Park and Serbian Armed Forces hunting grounds the broad-leaved forest areas occurred on the surfaces that were under the transitional woodland-shrub and vice versa. A similar situation is in the hunting grounds managed by PC ''Vojvodinasume'' where there is not only the most intensive logging of broad-leaved and coniferous forests but also the most intensive afforestation of mixed forests and transitional woodland-shrub. On the other hand, in the hunting grounds managed by hunting organizations, there is the highest area growth under the broad-leaved forest.

Decrease of grey partridge population is a global process that has been catastrophic in recent decades. In England, the number of this species declined by 80% in the period from the beginning of the fifties to the mid-eighties of the last century (Potts, 1986). In the Czech Republic from 1965 to the end of the eighties by as much as 95% (Štasny et al. 1997), and the situation is similar in Poland (Panek, 2005). The status of grey partridge in Serbia follows the same pattern as mentioned, with drastic decline (Ristić and Puzović, 2015). The reasons for such trend are numerous, directly conditioned and are often difficult to eliminate. It has been found that culling has no significant effect on the population (Ristić, 1992), but changes in its habitat in order to increase the yield of agricultural crops and chemical protection have very negative effect on partridge number. In order to study each type of game, it is necessary to know the basic elements of the population: density, growth, birth rate, mortality, migration movements and gender and age structure. Migration has no effect on changes in the partridge populations. Period of assessment 2010-2013: Serbia: 20,000-28,000 breeding pairs (bp), Vojvodina: 900-1,000 bp. Long-term population trend 1980-2003: MD (mean decrease in number), short-term population trend 2000-2013: MD (mean decrease in number). The number generally decreases, especially in Vojvodina, where it is endangered by intensive agriculture and the application of harmful biocides. It is necessary to improve the monitoring and develop the national action plan.

The necessity of economic life and economic development of every economy is the free movement of capital. The international movement of capital has its balance of payment when capital export represents economic surplus in relation to consumption of the national economy and the import of capital represents an increase of consumption in regard to the output of a national economy. Analysis of the influence of foreign direct investment (FDI) on economic growth of the host country, among other things, is emphasized in the function of the achieved phase of its economic development. Taking all this into consideration, the aim of this paper refers to an attempt to indicate the significance and the role of FDI as well as the importance of attracting foreign direct investment in B&H and the determination of the effects of FDI on the economy of B&H. In this regard, we will try to determine the level of FDI’s impact on some macroeconomic indicators in B&H (GDP, import, export, unemployment) by using contemporary SPSS statistical analysis program (model) and applying the methods (calculating coefficients) of correlation and regression analysis. In other words, we will determine the analytical expression used to describe a statistical relationship of these macroeconomic categories.

Radon problem has a special attention in many countries in the world and the most of them have established national radon programmes. The radon issues in Serbia have not been approached in a systematic and organized way. Currently, there are many research groups and institutions working in radon field, and it is a good basis to integrate all these activities into a comprehensive national programme to define the strategic objectives and action plan for the next few years. Also, Serbia as a candidate for membership in the EU is obliged to harmonize its legislation, including the field of radiation protection in which the radon issues has an important role. In this report, a brief history of radon research, present status and plans for the future activity on radon issues in Serbia are presented. Regarding the long-term plans, the establishment and implementation of the Radon Action Plan with the primary goal of raising awareness about the harmful effects of public exposure to radon and implementing a set of measures for its reduction. In that sense, the synergy between the national, regional and local organizations responsible for public health and radiation protection must be achieved.

In conditions of accelerated pace of life, reduced financial capacities and free time, modern hunters give a high priority to breeds of hunting dogs characterized by versatility or multiple usability in hunting. Accordingly, German Wirehaired Pointer is a kind of hunting dog which breeding is based on the principle of versatility. The objective of this work was to assess the quality of innate i.e. hereditary working properties of German Wirehaired Pointer in Serbia, in order to get an insight into their versatile usability in hunting and hunting tourism in Serbia. After analyzing the working results of 211 dogs, which had passed the spring breeding exams in the period from 2006. to 2013., the obtained data indicate that the quality of work, that is, the quality of innate working characteristics of German Wirehaired Pointer in Serbia, is increasing.

This paper presents development and implementation of an automated urban climate monitoring system in mid-sized European city Novi Sad (Vojvodina, Serbia). The urban climate monitoring network contains 27 stations (25 in urban area and 2 in non-urbanized environment). To determine the representativeness station cites we used Stewart-Oke Local Climate Zones (LCZ) classification, authors' local knowledge and field surveys to delineate urban area and surrounding environments. For LCZ determination we used Lelovics-Gál automated GIS (Geographic Information System) method. Stations measure the values and every 10 minutes send the readings related to air temperature, relative humidity, battery voltage, status value and other technical information to the main server. In order for the data stored in database server to be ready for usage in urban climate studies and for analyzing entire systems' work, we created Urban Path System tool (UP-SYS_tool) and URBAN-PATH Portal. Furthermore, the automatic data procession system visualizes the measured values from urban climate monitoring network in Novi Sad and informs the citizens about the most recent temperature, relative humidity and thermal comfort measurements. These, in situ measurements should provide long-term time series in order to highlight the thermal differences among different urban structures in city/es (intra-urban and inter-urban comparisons), and contribute to better understanding of urban climate in the urban canopy layer.

Total number and angular albedo were calculated for commonly used shielding materials, water, concrete, and iron, for photons with initial energies from 10 keV up to 10 MeV and normal incident angle. Influence of material thickness on total number albedo was also investigated. Double differential albedo was determined from simulation of photon transport through materials by using PENELOPE and MCNP software. Backscattered photons were scored and grouped in equal intervals of energy and angle. Analytical expressions for angular and total number albedo as a function of initial energy were obtained. It was shown that angular albedo can be determined with the same formula for three examined materials. Corresponding analytical expressions for number albedo as a function of material thickness were presented in this paper. [Projekat Ministarstva nauke Republike Srbije, br. 171021]

Conventional approach in the investigation of urban climate of Novi Sad has been done through simple urban-rural air temperature differences. These inter-urban air temperature differences showed how much is city warmer than its surroundings, so-called urban heat island (UHI) effect. Temperature differences exist inside the city as well. To get to know the intensity of these intra-urban temperature differences, installation of meteorological stations in different parts of the city or mobile measurements are needed. In 2012 started IPA HUSRB project made by Department of Climatology and Landscape Ecology (University of Szeged) and Faculty of Sciences (University of Novi Sad). The main goal of this project is the development and installation of wireless urban meteorological network (temperature and relative humidity sensors) in Szeged and Novi Sad. Before the deployment of sensors, necessary metadata about each potential urban meteorological station site needs to be collected. Field work, collected metadata and Stewart and Oke climate-based classification system from 2012 were used for defining the potential urban meteorological stations sites on the territory of the city of Novi Sad (Serbia) and its surroundings.

Within urban zones land cover, being the expression of human activities, could be greatly modificated by changes in urban surfaces. Land cover modifications can be measured with mathematical metrics that quantify different aspects of landscape pattern. This research examines land cover patches by a set of landscape metrics for area and size. (Number of patches - NP, CA - Class area, Mean patch size - MPS, % - class ratio). The classification of land cover patches was based on Corine Land Cover 2006 (CLC2006) seamless vector data. The main goal of the research is to investigate the impact of artificial surfaces on Urban Heat Island (UHI) in the City of Novi Sad. The methodology is based on crossing of landscape and geographical approach to UHI research. UHI metrics of Novi Sad reveal strong human impact indicating direct proportional relation between presence of artificial surface areas and increased air temperatures.

In this paper the stopping power was calculated, representing the electrons of the target atom as an assembly of quantum oscillators. It was considered that the electrons in the atoms have some velocity before interaction with the projectile, which is the main contribution of this paper. The influence of electron velocity on stopping power for different projectiles and targets was investigated. It was found that the velocity of the electron stopping power has the greatest influence at low energies of the projectile.

Standard Normal Homogeneity Test (SNHT) was applied for the detection of inhomogeneities in the time series of mean monthly air temperature data for 7 stations in Vojvodina Province (North Serbia) for the period 1949-2010. In time series of two stations missing data have been found, but gaps do not exceed 5% of dataset. These gaps have been filled in with values from the three best correlated neighbouring stations. Seven series of the moving average multi-annual air temperature (48-month and 72-month span) have been investigated. For inhomogeneity detection of these time series AnClim software package has been used, while further analysis used various statistical and cartography methods. Reference series have been chosen from 4 to 6 stations, based on distance, similar altitudes and squared correlation coefficient higher than 0.9. SNHT has been applied for detecting abrupt homogeneity breaks. The critical level of the test was 95%. Detected break points were compared to metadata records in order to diagnose causes of featured inhomogeneities. That type of information was crucial for applying calculated corrections of investigated series. After the homogenization process, the adjustment values have been analysed. The breaks which are explained in metadata are related to the relocations of the stations and show mostly low correction values. Differences between average values of raw and homogenised monthly time series are mostly within range from 0 to 0.12°C. According to low difference data, the results present very similar linear trends of original and homogenised time series for all stations. Still, there are a substantial changes of spatial distribution patterns. The patterns for homogenised series seem more regular, due to successful application of homogenisation process, making the image of climate variations in Vojvodina more reliable.

The aim of this paper is to determine the weakest point of Serbian destination competitiveness as a tourist destination in comparation with its main competitors. The paper is organized as follows. The short introduction of the previous research on the destination competitiveness is followed by description of the Integrated model of destination competitiveness (Dwyer et al, 2003) that was used as the main reference framework. Section three is devoted to the description of the previous studies on competitiveness of Serbian tourism, while section four outlines the statistical methodology employed in this study and presents and interprets the empirical results. The results showed that Serbia is more competitive in its natural, cultural and created resources than in destination management while, according to the Integrated model, Serbia is less competitive in demand conditions that refer to the image and awareness of the destination itself.

During the history, the Danube valley was often devastated the northwest part of Bačka. However, the Danube river created also one of the most rich full wetland complexes in Serbia, Special Nature Reserve 'Gornje Pondunavlje' (Upper Danube). Hunting-ground 'Apatinski rit' is located within borders of SNR 'Gornje Podunavlje'. The people from this region constructed river embankments and other fortification objects to protect themselves from the floods, but still there are spacious areas that are not protected. In those areas, many floral and animal species (including game) face floods every year. High water level of the Danube River is the most dominant factor of change of habitat conditions in hunting ground 'Apatinski rit'. About 60% of the territory of 'Apatinski rit' are in the zone of floods. During the extreme high water level, game animals suffer serious losses. The purpose of this paper is to present possible application of geographic information system (GIS) in flood prediction in hunting-ground 'Apatinski rit' in order to reduce negative flood impacts. GIS technologies are used in many aspects of flood identification, prediction, and hazard mitigation. In this paper a 3D model is introduced to realize the flooded areas. The flooded areas are estimated based on the Danube water levels and topography of the surrounding terrain. The estimated flooded areas based on several water levels are shown in the paper. During the flood some parts of hunting ground are under water, and some higher courts remain dry. By using 3D model, all the isolated 'islands' with trapped game can be located during the floods, which is crucial for rescue intervention priorities and decision making during the flood.
