One of the essential activities for sustainable local economic development is continuous improvement of business environment which can be carried out through the business-friendly certification as objective benchmarking process, which is influenced by many factors - criteria that could be analyzed using multi-criteria decision-making methods. Determining criteria weights is the most important task regarding these methods for which a number of methodologies based on different approaches were developed. These methodologies could be generally divided into two groups: subjective and objective. Shortly, these methodologies quantify given preferences using knowledge of experts if they are subjective or using calculations from available data if they are objective. Methodologies from these two groups give different results in a wide range of values. Therefore, it is useful to create composite indicators using aggregation of both approaches in order to reduce the influence of their bad individual characteristics and, therefore, achieve a balanced symmetrical approach. The purpose of this paper is constructing one efficient model that solves a problem of the planning of sustainable local economic development in the Republic of Serbia. Our approach uses the aggregation of the entropy method, as one objective approach, and the analytical hierarchy process, as a subjective approach, in executing business-friendly certification process. The implementation of the proposed approach has been demonstrated as a part of a business-to-government (B2G) platform called “Multi-Criteria Support System for Analysis of the Local Economic Environment” in the City of Niš.

Local self-government has the task of enabling stable economic development, in addition to enabling a normal quality of life for citizens. This is why the state government should provide guidelines that will improve the local business climate, and by doing so enable local economic development. This can be done through the introduction of a business-friendly certification procedure, which is influenced by uncertain inputs and influences many output factors. Each local government has the important task of determining its rank of efficiency in this process. A number of methodologies developed to solve this problem are generally divided into two groups: Parametric and non-parametric. These two groups of methodologies could provide quite different results. Therefore, the purpose of this paper was to create a model using both approaches to achieve a balanced symmetrical approach that produces better results than each approach individually. For this purpose, the paper describes a multicriteria decision aid-based model of optimization to evaluate the effectiveness of this process, integrating classification, data envelopment analysis, and stochastic frontier analysis, as well as its application in a case study of business-friendly certification in the Republic of Serbia.

The main motivation to conduct the study presented in this paper was the fact that due to the development of improved solutions for prediction risk of bleeding and thus a faster and more accurate diagnosis of complications in cirrhotic patients, mortality of cirrhosis patients caused by bleeding of varices fell at the turn in the 21th century. Due to this fact, an additional research in this field is needed. The objective of this paper is to develop one prediction model that determines most important factors for bleeding in liver cirrhosis, which is useful for diagnosis and future treatment of patients. To achieve this goal, authors proposed one ensemble data mining methodology, as the most modern in the field of prediction, for integrating on one new way the two most commonly used techniques in prediction, classification with precede attribute number reduction and multiple logistic regression for calibration. Method was evaluated in the study, which analyzed the occurrence of variceal bleeding for 96 patients from the Clinical Center of Nis, Serbia, using 29 data from clinical to the color Doppler. Obtained results showed that proposed method with such big number and different types of data demonstrates better characteristics than individual technique integrated into it.

* ajber pretnje predstavljaju jednu od najvećih pretnji u modernim sukobima, jer relativno male snage i tzv. nepoznati napadači mogu naneti ogroman gubitak moćnijima, posebno u domenu upotrebe informacione tehnologije. Stoga, sve zemlje sveta poklanjaju izuzetnu pažnju zaštiti (odbrani) od sajber napada (pretnji). Evropska unija prednjači u nastojanju da se odbrana od sajber pretnji reguliše u normativno-pravnoj i strategijsko-doktrinarnoj sferi. Za tu svrhu posebno je značajna Strategija EU, koja ima značaj i za Republiku Srbiju.Ključne reči: EU, Evropska strategija bezbednosti, sajber pretnje Uvod trategija nacionalne bezbednosti predstavlja opšte programsko stanovište države u oblasti bezbednosti, čijom realizacijom se štite nacionalni interesi od rizika i pretnji. Izradi strategije treba pristupiti kroz više oblasti (sudstvo, politika, ekonomija, postojeće institucije...), kako bi se predvidele pretnje koje potencijalno ugrožavaju sigurnost države i građana koji u njoj žive.Savremeni bezbednosni izazovi, koji se javljaju u oblastima politike, ekonomije, finansija, energetike, ekologije, religije, kulture, informatike i drugih oblasti društvenog života, nameću potrebu uključivanja većeg broja državnih i društvenih organizacija u poslove kojima se osigurava nacionalna bezbednost. Pored povećanja broja organizacija koje se bave pitanjima nacionalne bezbednosti, postoji potreba da se na bezbednosne izazove i pretnje odgovori na jedinstven i usklađen način.Republika Srbija u svojoj nacionalnoj strategiji ističe vrednosti kao što su zaštita bezbednosti građana, izgradnja poverenja, unapređenje stabilnosti u regionu, saradnja i partnerstvo sa međunarodnim bezbednosnim organizacijama i institucijama demokratskih država, ali joj je primarna potreba za očuvanjem suverenosti i integriteta države. Ovakav pristup suočava se sa novim izazovima, koji se javljaju sa ubrzanim razvojem informacionih tehnologija. Shodno tome, neophodno je da i u toj sferi Republika Srbija uskladi svoje zvanične bezbednosne stavove sa evropskim, kako bi u budućnosti svojim rešenjima predupredila i odgovorila na nove izazove.Strategija nacionalne bezbednosti Republike Srbije se u svom uvodnom delu bavi bezbednosnim okruženjem, te detaljnije razrađuje globalno i regionalno okruženje, kao i bezbednost Republike Srbije. U okviru globalnog okruženja ističu se nova bezbednosna kretanja u
