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.

Throughout Europe agriculture intensification during the last decades has dramatically changed the structure of the farmland landscape with an intensive impact on ecosystem stability. Changes in the production led to decreased habitat heterogeneity and to decline in biodiversity, including the European hare (Lepus europaeus), especially in the lowland regions. Even though European hare mostly adapted to intensive agricultural habitats, the population densities have decreased throughout Europe since the 1960s. Previous research reported field size to be one of the most important predictors of the hare population. We aimed to assess the effect of habitat heterogeneity and structure on hare habitat selection i.e. population density. Using hunting organization census data we explored the population density and habitat preference of the European hare in spring 2020 in the hunting ground, Bačka - Bački Petrovac. The average population density of European hare significantly differed between four fractions of the hunting ground - Bački Petrovac, Kulpin, Gložan, and Maglić. Density varied from 27 in Bački Petrovac to 50 individuals per 100 ha in Maglić. The population was negatively affected by mean patch size and by the area under no vegetation during the winter period. Conservation measures should focus on enhancing habitat heterogeneity by reducing field size, and fostering sowing during the late autumn period. [ABSTRACT FROM AUTHOR]

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.

Let χ∈H1(Σh,Q)$\chi \in H^1(\Sigma _h,\mathbb {Q})$ denote a rational cohomology class, and let Hχ$\operatorname{H}_\chi$ denote its Hodge norm. We recover the result that Hχ$\operatorname{H}_\chi$ is a plurisubharmonic function on the Teichmüller space Th${\mathcal {T}}_h$, and characterize complex directions along which the complex Hessian of Hχ$\operatorname{H}_\chi$ vanishes. Moreover, we find examples of χ∈H1(Σh,Q)$\chi \in H^1(\Sigma _{h},\mathbb {Q})$ such that Hχ$\operatorname{H}_\chi$ is not strictly plurisubharmonic. As part of this construction, we find an unbranched covering π:Σh→Σ2$\pi:\Sigma _{h}\rightarrow \Sigma _2$ such that the subgroup of H1(Σh,Q)$H_1(\Sigma _{h},\mathbb {Q})$ generated by lifts of simple curves from Σ2$\Sigma _2$ is strictly contained in H1(Σh,Q)$H_1(\Sigma _{h},\mathbb {Q})$. Finally, combining the characterization theorem with the Riemann–Roch, and the Li–Yau [Invent. Math. 69 (1982), no. 2, 269–291] gonality estimate, we show that geometrically uniform covers of Σg$\Sigma _g$ satisfy the Putman–Wieland Conjecture about the induced Higher Prym representations.
