The objective of this study is to allow a better understanding of the role of industry 4.0 technologies, especially filament extrusion technology in the reduction of costs, environmental impact, energy consumption, and the possibility to expand the range of printable materials. The study focuses on the desktop Filament Extruders available in the market now, where these machines are assessed and future possible modifications for these apparatuses are presented. The research leading to the publication of this study consists of a review of the existing literature, in addition, information from different extruders manufacturers’ websites has been used.  The study has demonstrated that the extrusion of material at home is still not an exact science, and the process ends up costing the user large sums of money over time. However, there are still limitations to the use of this technology such as the lack of standardized extrusion settings, the necessity of pre-drying the pellets, and the complexity of the extruder cleaning process after each use.

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.

Corruption is undoubtedly present everywhere in Bosnia and Herzegovina, in all pores of society and on an increasing scale. The fight against corruption is a great challenge for the most developed countries in the world. Therefore, it is not surprising that Bosnia and Herzegovina, burdened by political problems and poverty, finds it difficult to find effective mechanisms to combat this extremely negative phenomenon. The reasons for poor results in the prosecution of corrupt crimes range from the very nature of the phenomenon of corruption, which is shrouded in secrecy due to the interests of participants, which makes it difficult to disclose, to insufficiently good institutional and legal solutions. The aim of this paper is to determine the awareness of B&H citizens about corruption in the workplace and the way they relate to corruption in everyday life, but also to analyze the performance of state institutions in preventing and combating corruption. Based on the defined problem to be investigated and the set goals, the methodology used during the research was determined. The scientific-research character of this paper is based on the analysis of relevant scientific literature and modern sources using the methods of examination, methods of analysis, methods of comparison, methods of description and methods of deduction.

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.

Istraživanjem se nastojalo utvrditi uticaj afektivne vezanosti u djetinjstvu kao prediktora stresa, anksioznosti, depresije i adverzivnih iskustava kod mladih. Uzorak istraživanja činilo je 202 ispitanika, ujednačeni po polu (Nm=102; Nž=100), koji dolaze sa područja grada Bihać i okoline. Za potrebe istraživanja korišteni su upitnik depresivnosti, anksioznosti i stresa (DASS skala), upitnik adverzivnih iskustava iz djetinjstva (ACE) i upitnik porodične afektivne vezanosti (PAVb). Nepotpunost porodice narušava porodičnu strukturu i remeti njeno prirodno stanje što može dovesti do patologije afektivne vezanosti koja se u našem istraživanju pokazala kao značajan prediktor internalizirajućih (simptomi anksioznosti i depresije) promjena u ponašanja kod mladih (p.01). Nekonzistentnost odnosa u porodici dovodi i do potencijalno traumatskih, adverzivnih, iskustva koja je osoba mogla da doživi u periodu od rođenja do 18 godine života a čija simptomatologija je pokazana na statistički značajnom nivou (p.01) u ovom istraživanju. Istraživanja ukazuju na konzistentne spolne razlike u kojima žene imaju intezivnije internalizirajuće simptome od muškaraca što u ovom istraživanju nije pokazano kroz statističku značajnost. Naime, zbog razlika u adolescenciji koje postoje u stilu suočavanja sa stresnim situacijama između muškaraca i žena, rezultati ovog istraživanja ukazuju da postoje razlike u kojima muškarci pokazuju statistički značajnije (p.01) ispoljvanje depresivnosti i u prosjeku izraženije simptome anksioznosti i adverzivnih iskustava, a žene samo statistički značajno (p.01) ispoljavanje simptoma stresa.

Every organization is made up of employees who can be its great strength but also a weakness, and the results, quality of work and achievement of organizational goals are largely determined by the behavior of the people who make it up. One of the key factors that influence the behavior of people in general, as well as the behavior in the work organization and attitude towards work are motives. Starting from the fact that human behavior is driven by different motives, that different people have different structure of motives and needs, the aim of this research is aimed at conducting the segmentation of employees in selected businesses in Bosnia and Herzegovina, engaged in different types of activities and of different structures of equity, according to socio-demographic factors – gender, age of respondents, years of service, marital status, type of education, the amount of monthly income of employees and the amount of family monthly income of employees. Also, the goal is to determine whether there are significant differences in the motives of individual groups (segments) of employees and how such indicators can contribute to the creation of an adequate motivational strategy within the work organization

It is the fact that sexual deviations and delicts are present in all cultures and within all peoples during the whole history of mankind and this have always caused the attention of theoreticians in their quest for its roots. Having on mind this fact, we have analysed the family dynamics during early childhood of sexual delinquents through the search for the differences in perceived parental acceptance or rejection, family affective attachment and accepted script injunctions – in relation to healthy examinees. The research is based on sample of 42 examinees categorised in two groups: a group of sexual delinquents and a group of examinees from general population without psychological disorder diagnosis. The analyses of perceived index of parental acceptance is carried out by Rohner PAR-Q questionnaire, for the determination of affective attachment patterns we use modified Brennan questionnaire for the estimation of family affective attachment, while level and the nature of acquired script injunctions have been asnalysed by the Scale of script injunctions. The results show that there are statistically significant differences between the two groups regarding dominating patterns of family affective attachment with more dominant insecure attachment in the group of sexual offenders. Too, one of the characteristics of this group is above average exposure to the existence injunction, value injunction, Don`t be a child injunction, and health injunction, while differences regarding perceived index of parental acceptance/rejection are not statistically significant

The aim of this paper is to get acquainted with the process of integration of Bosnia and Herzegovina into the European Union. On May 26, 1999, the Commission presented a proposal to initiate the so-called Stabilization and Association Process. This was approved at the meeting of the Council of the European Union in Luxembourg on June 21, 1999. The Stabilization and Association Process was formalized at the Zagreb Summit in 2000, at which the Union reaffirmed its desire to contribute to the consolidation of democracy and to give decisive support to the process of reconciliation and cooperation between the countries of the Western Balkans. The term Western Balkans is political and is used to distinguish this group of countries from previous ones that have already established relations with the European Union. Methods of analysis, synthesis, induction, deduction, abstraction, description, compilation and content analysis were used in the research. The research shows that Bosnia and Herzegovina still does not sufficiently meet the criteria relating to the stability of institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities, set by the Copenhagen European Council in 1993. Bosnia and Herzegovina must align its constitutional framework with European standards and ensure the functionality of its institutions in order to be able to take on the Union’s obligations. In this regard, it is necessary to reform the institutions so that they can effectively participate in decisionmaking at EU level and implement and enforce the acquis.
