The word rehabilitation is of Latin origin (sanacio) and means treatment, from the point of view of the economy of the company, rehabilitation means economic and technical-organizational measures that should contribute to the recovery of the company, in the sense of making it liquid and profitable again. A company is considered sick if, in the long run, it is unable to meet its obligations and operates at a loss. The causes of the disease can be external and internal. Financial difficulties, manifested in illiquidity and unprofitability, cause the need for rehabilitation. Initiation of remediation presupposes remediation eligibility, which exists if permanent recovery of the company is possible. Determining the suitability of rehabilitation involves examination and selection of measures, the implementation of which ensures the permanent recovery of the company, in the sense of re-establishing the financial balance and returning to the profit zone.

This paper explores the food industry business market as an example, highlighting the key role of market research in successful economic recovery. Through this example, market research becomes a fundamental framework for identifying the changes that a company needs to implement in its operations in order to become more competitive. The example will show the market research of companies from the food industry. There is no successful economic rehabilitation without market research. This example can serve as a framework for market research, which provides answers to the question of what the company needs to change in its business in order to be more successful than the competition. The research results have significant implications for managers, experts and political decision-makers, providing them with information necessary for effective management of financial crises and ensuring the stability of companies, as well as a faster understanding of the competitive business environment.

The laws in Bosnia and Herzegovina that partially regulate the subject areas are outdated, long since overcome and almost completely non-functional, which effectively prevents the introduction of new technologies, which are becoming more and more convergent day by day with the development of digital services that are based on various types of electronic communication infrastructure. This type of legislation in Bosnia and Herzegovina discourages investors from investing in the development of communication infrastructure, which ultimately leads to limited service or lowquality service for the citizens of Bosnia and Herzegovina. High-quality and modern regulation of the field of electronic communications is achieved first of all so that all legislative levels in Bosnia and Herzegovina, in accordance with their constitutional competences, pass complex and detailed laws that will regulate the field of electronic communications, following the example of the legislative achievements of the European Union in this areas. Bearing in mind the past experiences in Bosnia and Herzegovina, probably a more functional way is for all legislative levels in Bosnia and Herzegovina, in accordance with their constitutional competences, to pass laws that will regulate the field of electronic communications in such a way as to prescribe the basic principles and basic frameworks of regulation this area, again following the example of the legislative achievements of the European Union in this area.

This paper presents the binary symmetric channel as a common model of the communication channel used in theory of coding and theory of information. Since there is no noise in the channel, the data transmission delay is very small, which is why data can be transmitted quickly and in real time, without many errors, which greatly determines its practical application. Therefore, the theoretical basis of the functioning of the channel itself and its practical advantages will be presented in the text. The concept of binary coding will also be explained with the use of block codes that create the possibility of correcting eventual errors, as well as the application of a binary symmetric channel in improving signal interference when using a wireless network.

Understanding elliptic curves contributed to solving mathematical problems in number theory that had been unsolved for centuries. Elliptic curves were also used in solving one of the millennial problems, which is Fermat's last theorem. They are also connected with many hypotheses and problems in mathematics that have yet to be solved. Elliptic curves defined over finite fields are widely used in public key cryptography, since they have proven to be groups that have the best properties for implementing the Diffie-Hellman protocol. This article provides an overview of the theoretical assumptions that are necessary for the development of cryptographic algorithms based on elliptic curve cryptography, which includes defining elliptic curves, defining the properties of arithmetic operations on elliptic curves used in cryptography with reference to curves defined over finite fields.

In order to efficiently manage air quality at the location of Banja Luka city, a functional system for monitoring and controlling the degree of air pollution, that is to say air quality monitoring, has been established. Air quality monitoring is performed by the Mobile Ecological Laboratory (MEL) at three locations in the settlements of Paprikovac, Borik and the City Centre. The objectives of air quality monitoring can be divided into two groups: the first group consists of the objectives of the monitoring program for a medium-industrialised city with an existing or potential problem of air pollution. The second group consists of special air quality monitoring objectives, whose nature is such that their implementation is a matter of free choice, and usually more complex solutions are required. The basic air quality monitoring program should provide the essential data needed to develop air quality standards and enable the development of an acceptable air quality protection program. The goal of the basic air quality monitoring program is: to monitor long-term trends in air pollution in order to determine the degree of improvement or deterioration of air quality in urban and industrial environments. Measurements are usually performed at multiple measurement sites by collecting and analysing a 24-hour sample. Measurement data for at least five consecutive years are required to determine air pollution trends. Air quality is assessed based on the obtained data and on the basis of comparison with standards. In accordance with the above, this paper presents the air quality through the values of the following pollutants: SO₂, O₃, CO, NO₂, PM₁₀ and Soot. The air quality of Banja Luka (from the aspect of the presence of sulphur dioxide and soot) was analysed, before and after the war, based on the available literature.

The paper analyzes the position of national minorities in the Western Balkans region, with an emphasis on the countries created through former SFR Yugoslavia’s dissolution, which are characterized as new national states. It has been pointed to the specificities of this form of national state, primarily nationalism as the basis in all the domains of functionality, which is the main reason for the negative relation toward minorities. The accession to the European Union is the main motivation factor toward solving the issues of the minorities in this region. The situation in Bosnia and Herzegovina is especially complicated considering that the specific solution of national minorities’ status is one of the causes of stagnation of this country in European integration process.

The subject of this paper is models of consociational democracy in Austria and Bosnia and Herzegovina. The aim is to define in a comparative analysis the similarities and differences between consociational systems of government in these two countries, their practice and scope. Based on these conclusions, we draw new knowledge in the field of activities and possibilities of consociational arrangements in the divided societies of modern Europe. The scientific justification of this paper is that through the analysis of different consociational democracies and their practical experiences, the scope of this form of democratic rule is assessed, and the conclusions are theoretically added to the existing fund of scientific knowledge about this phenomenon. The social contribution of the paper is in the fact that consociational democracy is an increasingly common solution for many divided societies and therefore the analysis of existing consociational democracies is a socially justified topic.

Foreign direct investments in the Republic of Croatia has been systematically monitored since 1993. During the war years, the inflow of foreign capital, both in the form of direct and portfolio foreign investments, was insignificant. Significant foreign investment activity has been present since 1996. Aware of the importance that FDI (Foreign Direct Investment) can have on the recipient country, both as a factor in accelerated economic development, and as a source for financing the deficit on the current account of the balance of payments, Croatia has declaratively promoted a policy of attracting foreign capital. Although in the first few years after the war this promotion was mostly aimed at the Croatian diaspora, under the pressure of the international community, privatization began in the banking and telecommunications sector, and since the post-war years, the largest amount of foreign capital has been directed there. Thus, in the second part of the 1990s, after the normalization of the situation in the country, Croatia collected a total of nominally around USD 4.5 billion in foreign direct investment, mostly through privatization, and the largest inflow of foreign currency was realized in 1999, in the amount of 1, 2 billion USD (first round of privatization of HT). This paper analyses the factors affecting foreign direct investment and the strengths, weaknesses, threats and opportunities for encouraging the inflow of foreign direct investment into the economic framework of the Republic of Croatia and presents the competitiveness index of the structures and activities of foreign direct investment in the Republic of Croatia. In conclusion, it can be emphasized that since independence, the Republic of Croatia has been making efforts to attract as many foreign investments as possible, while achieving limited results.

In order to determine the most effective method of advertising on Instagram and attract users of the application to become permanent followers of the site, for the purposes of this paper, we used primarily collected data through weekly testing of seven selected methods. Five organic (increasing the number of followers and interactions – removing inactive followers, tracking posting time, changing the number of “tags”, “liking” other users’ content and a combination of 4 “likes” and 1 comment) and two paid directly from the Instagram application (foreign advertising and advertising for the domestic market). The results of the research were processed by descriptive statistics. The paper represents the synergy of theoretical and empirical work. The first part will theoretically describe facts related to the second, empirical, part of the paper and the case study, which was designed and researched. The idea stemmed from the need to select the most successful methods from the large number of the ones used to organically increase the number of followers and the number of interactions on the site. There was also a need to check whether these methods were as good for advertising as they were paid for. Also, it was necessary to determine whether they bring results in relation to the invested engagement. Comparing the achieved results of organic and paid advertising methods, it was found that certain organic advertising methods give better results in some parameters than paid ones, while paid ones give better results in other parameters.

Semarang, as the capital city of Central Java province, Indonesia, has been exercising its own diplomacy in pursuit of its interests related to economy and disaster. Under the leadership of mayor named Mr. Hendrar “Hendi” Prihadi, the city administration has been practicing city diplomacy as a means to attract both domestic and foreign investors by convening a business forum, called Semarang Business Forum (Sembiz), and to explore partnership in building the city’s disaster resilience by joining a city network, called 100 Resilient Cities (100RC). According to the argument by Keating (1999) in explaining Para diplomacy, this paper argues that Hendi administration’s strategies in exercising city diplomacy were shaped by its motives, as reflected in Regional Long Term Development Plan (RPJMD), and the opportunity structure in terms of existing regimes where the city could observe suitable cooperation. This paper finds that Hendi administration benefited from city diplomacy in solving local urban issues, such as the tidal and flash flooding problem in the coastal area of Semarang.
