The purpose of this study is to examine the impact of Serbian tourists’ risk perception on their intentions to travel during the COVID-19 pandemic with the control of socio-demographic characteristics. This research was conducted in the period from 18 May until 24 May 2020, on a sample of 348 respondents, through an online questionnaire. The principal component analysis identified five categories of the perceived risk affecting travel intentions during the COVID-19 pandemic: the health risk, the psychological risk, the financial risk, the destination risk and the travel risk. Logistic regression was used to examine the way in which risk perception affects the intentions and destinations of travel during the COVID-19 pandemic. The research findings indicate that the risk perception (health, psychological, financial and destination risks) among Serbian tourists negatively affects their travel intentions during the COVID-19 pandemic. In terms of travel destinations, the results indicate that the travel risk negatively affects travel abroad, while the health risk, being on the verge of significance, proved to be a predictor of travel abroad during the COVID-19 pandemic. Furthermore, the variable of monthly income of the respondents was singled out as a significant predictor of travel abroad during the pandemic. Finally, the implications, limitations and recommendations for future research are presented in the paper.
Агротуризам терминолошку употребу у етимолошком погледу налази у аграру, што значи да је осн ова развоја овог облика туризма пољопривреда. Али пољопривреда не подразумева само традиционалне и екстензивне форме, већ и напредне које су интензивног карактера, као на пример развијени комбинатски тип. Није спорно да се рурални туризам везује, између осталих и
Велики број термоминералних извора, дуга традиција бањских места и њихов значај за развој туризма учинили су да бањски туризам постане један од најразвијенијих облика туризма у Србији. Овај облик туризма је, током времена, испољавао бројне специфичности. Многе од њих су присутне и данас, а односе се на наглашену концентрацију промета у току летњих месеци, све краћи просечан боравак гостију, као и велико учешће комплементарних смештајних капацитета у односу на основне. Циљ овог рада је наглашавање еколошке компоненте у одрживом развоју бањског туризма у Србији.
The paper shows the microbiological activity of silver nanoparticles (AgNPs) stabilized with dextran derivatives with carbox-ymethyl dextran (CMD) and dextran sulfate (DS). Non-toxic, green procedures for the synthesis of AgNPs with CMD, DS were developed. The increasing application of silver nanoparticles in many areas, especially favors the so-called non-toxic, i.e. “green” synthesis procedures. Unlike physical and chemical synthetic methods, green synthesis has a number of advantages: lower energy consumption, simple execution, costs are reduced, use of non-toxic chemicals as reducing and stabilizing agents. Nanoparticles AgNPs-DS and AgNPs-CMD showed microbiological activity against the analyzed test microorgan-isms. Silver nanoparticles obtained in this way, due to their stability and preserved antimicrobial activity, can be widely used in various branches of industry. The results of testing the antimicrobial activity of synthesized nanoparticles from the technologi-cal aspects are important; these compounds have potential application in the biomedical field, and simple procedures have many advantages, such as low costs, compatibility for medical and pharmaceutical applications, as well as the production of other commercial products in the food industry.
