ATTITUDES OF SERBIAN URBAN RESIDENTS TOWARD TOURISM DEVELOPMENT

Tourism is one of the main driving forces of economic development in modern era, offering new opportunities for employment, increase in living standard and improvement of quality of life in the cities. Over time, tourism has had influence on urban environment and its inhabitants, through reshaping their initial attitudes regarding benefits and deficiencies of its further development. Urban population is not homogeneous and as such is not uniform in perception related to tourism development, but some general conclusions can be drawn. This study aims to understand perception of residents about tourism development in city of Kragujevac, given that city authorities are keen to extend number of tourist visits and overnight stays within their tourism campaign efforts. The objective is to identify key factors related to the significance of tourism development based on attitudes of inhabitants of Kragujevac, as well as to determine whether there are differences in attitudes based on age and place of birth of the respondents. Through factor analysis seven factors surfaced, including: economic development, healthy and clean environment, development of local communities, sport and entertainment, preservation of environment, culture and real-estate. Results suggest that there is statistical difference in attitudes among respondents’ in terms of their age and place of birth.Key words: Attitudes, tourism development, urban residents, city of Kragujevac. 

Linear Diophantine Fuzzy Rough Sets: A New Rough Set Approach with Decision Making

In this article, a new hybrid model named linear Diophantine fuzzy rough set (LDFRS) is proposed to magnify the notion of rough set (RS) and linear Diophantine fuzzy set (LDFS). Concerning the proposed model of LDFRS, it is more efficient to discuss the fuzziness and roughness in terms of linear Diophantine fuzzy approximation spaces (LDFA spaces); it plays a vital role in information analysis, data analysis, and computational intelligence. The concept of (,)-indiscernibility of a linear Diophantine fuzzy relation (LDF relation) is used for the construction of an LDFRS. Certain properties of LDFA spaces are explored and related results are developed. Moreover, a decision-making technique is developed for modeling uncertainties in decision-making (DM) problems and a practical application of fuzziness and roughness of the proposed model is established for medical diagnosis

NEW SOCIAL CIRCUMSTANCES AND EDUCATION IN AGROBUSINES

In the article, author first of all underline interdependence between human resources and state and perspectives of agriculture in each country, including transitional countries. But, on other side, there are not necessery level of consciousness about importance of developement of human resources and developement of modern agroculture based on market competetion. Anyway, regardless of many obstacles, today ve have on global level process of trasformation from traditional agroculture production to modern market agrobusiness. Same process, but in specific forms we have today in countries of transition, including Serbia. Mentioned process has one of corner stones in one of most important characteristic of agroculture, same in contemporary and previous age – visible, open, dominant relationship between human been and nature. State of human resources in agroculture is so far of satisfied, and worse in comparison with state of human resources in industry, and other parts of national economy. It is one of strongest obstacles and limitations for faster and more eficient developement of agrobusiness in Serbia. In same time, process of developement of human rosources in agroculture always have specific forms. One of most important differences is in the field of vertical and horisontal social mobility. Finally, main question is – is possible to create and develop new social group – which will have all necesery capacities to bi social pillar of new concept and practice of agroculture in Serbia

Examination of the efficacy of various feed additives on the pathomorphological changes in broilers treated with T-2 toxin

A 21-day-long experiment was performed on 160 one-day-old 'Ross' broiler chicks. This research was done with the aim of investigating pathomorphological changes in broilers exposed to a relatively small amount of T-2 toxin (2 ppm) and the possibility of prevention and/or alleviating adverse effects of T-2 toxin using various feed additives. Pathohistological examination showed negative consequences of T-2 toxin in all examined organs as degenerative changes developed in small intestine mucosa, enterocites and hepatocites necroses, as well as lymphocites depletion in bursa of Fabricius. Disparately from inorganic (Minazel-plus, Mz) and organic (Mycosorb, Ms) adsorbents, which did not provoke protective effects, in liver, small intestine and bursa of Fabricius of broilers who were given feed with T-2 toxin and mixed adsorbent (Mycofix-plus, Mf), mostly preserved structure of these organs could be noted.Eksperiment je izveden na 160 jednodnevnih brojlerskih pilića provenijencije 'Ross', u trajanju od 21 dan. Istraživanja su bila usmerena na omogućavanje detaljnijeg uvida u patomorfološke promene kod brojlera izloženih dejstvu relativno niskih doza T-2 toksina (2 ppm), kao i mogućnosti prevencije ili ublažavanja štetnih efekata korišćenjem različitih adsorbenata. Patohistološkom analizom isečaka tankog creva, jetre i Fabricijeve burze, uočeni su efekti T-2 toksina u svim ispitivanim organima, u vidu degenerativnih promena na sluznici tankog creva, nekroze enterocita i hepatocita, kao i deplecije limfocita u Fabricijevoj burzi. Za razliku od neorganskog (Minazel-plus, Mz) i organskog (Mycosorb, Ms) adsorbenta čijom primenom nije došlo do zaštitnog efekta, u tkivnim isečcima jetre, creva i Fabricijeve burze kod brojlera koji su putem hrane dobijali T-2 toksin i mešoviti adsorbent (Mycofix, Mf), zapaža se uglavnom očuvana struktura ispitivanih organa

Robust Aggregation Operators for Intuitionistic Fuzzy Hypersoft Set with Their Application to Solve MCDM Problem

In this paper, we investigate the multi-criteria decision-making complications under intuitionistic fuzzy hypersoft set (IFHSS) information. The IFHSS is a proper extension of the intuitionistic fuzzy soft set (IFSS) which discusses the parametrization of multi-sub attributes of considered parameters, and accommodates more hesitation comparative to IFSS utilizing the multi sub-attributes of the considered parameters. The main objective of this research is to introduce operational laws for intuitionistic fuzzy hypersoft numbers (IFHSNs). Additionally, based on developed operational laws two aggregation operators (AOs), i.e., intuitionistic fuzzy hypersoft weighted average (IFHSWA) and intuitionistic fuzzy hypersoft weighted geometric (IFHSWG), operators have been presented with their fundamental properties. Furthermore, a decision-making approach has been established utilizing our developed aggregation operators (AOs). Through the established approach, a technique for solving decision-making (DM) complications is proposed to select sustainable suppliers in sustainable supply chain management (SSCM). Moreover, a numerical description is presented to ensure the validity and usability of the proposed technique in the DM process. The practicality, effectivity, and flexibility of the current approach are demonstrated through comparative analysis with the assistance of some prevailing studies
