The subject of the research is the analysis of services that should be offered by public administration toward legal entities and natural persons. We will suggest that it uses real-time intelligent IT systems based on data storage based on the data warehouse. Our opinion is that such systems implemented in the public administration of Bosnia and Herzegovina could offer an appropriate service to each user at a time when they need the service in a form that suits them, on the spot where he is in the moment of delivery and in the quantity that he needs. In order for a public administration to be able to offer an appropriate service, it must know its users much better and know which service they need at what time. In this paper, we analyze self-service as well as the necessary activities for all that. These are all activities that should be carried out in the future, and this work could contribute to the implementation of these processes.

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.

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.

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.

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.

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 goal of this article is to inform the reader of three distinct types of biomedical materials applied in the production of dental implants, focusing on characteristics and categorizations of biomaterials based on: titanium (Ti + its alloys), commercially manufactured synthetic polymers (polyetheretherketone) and ceramic materials (zirconium dioxide). Considering the development and construction of implants, specific material requirements are named (mechanical properties), corrosion resistance, compatibility, morphology, etc. Each of these materials represents a specific group of biomedical materials and has a number of advantages. However, in relation to the differences in their nature (metal, plastic, ceramic base), it is necessary to approach the choice of material for dental implants with respect to the specific implant design and the patient’s health limitations.

An administrative contract is a specific contract with a special legal regime, subjects and characteristics that classify it as an institute between private and public law. The paper presents a comparative analysis of the general principles of contract law, and above all civil (private) law and administrative contract. This analysis should answer the questions of the basis of the contractual obligation, ie the basic elements that create a contractual obligation. The paper presents the most important principles, as well as general elements of the contract on the one hand and basic characteristics of the administrative contract on the other, in order to better understand their legal nature, similarities and differences, especially the legal nature of the administrative contract and its place in contract law.

As a potential candidate for membership in the European Union and Bosnia and Herzegovina, a country committed to the Euro-Atlantic integration process has committed itself to strengthening the rule of law and strengthening institutions in the field of justice and home affairs. One of the important activities in this process is the adoption and implementation of public policies in the field of combating money laundering, bearing in mind that this social scourge in its manifestations is the greatest threat to the stability and smooth functioning of a country. Money laundering is a global problem of the twenty-first century. As a form of economic crime, the money laundering process is represented both nationally and internationally. 
Although there are a large number of definitions of money laundering, it can be said that it consists of shorter or longer movements of funds acquired through illegal activities, in order to obtain seemingly legal means through the cycle of transformation. The complexity of the fight against money laundering and the problems of combating various forms of money laundering go beyond the possibilities and efforts undertaken by the competent authorities and government institutions. All countries should go ahead of money launderers, that is, they should go ahead in designing and prescribing methods and ways of fighting, but they should also not allow criminals to use a corrupt and unregulated institutional framework and gain lucrative money laundering income.

Village – Owned Enterprises (BUMDes) was developed to increase the village revenue and drive the people’s economy through resource and village asset management. The existence of BUMDes is expected to improve village potential and become a pillar of the community’s economy. Not only oriented on increasing the village local revenue, but BUMDes must also have a social mission to help the villagers, especially during the COVID-19 pandemic. The study method employed was descriptive qualitative, and the data were collected through interviews, observations, and documentation. Informants were selected through purposive sampling out of the various parties related to BUMDes in the Polanharjo Sub-district, Klaten District. The results of the study showed that the mass development of BUMDes as a top-down policy without any consideration of the local potential of each village has caused a lack of support from the community and has led to the lack of development of BUMDes, making many lapses into a stasis. However, there are a few BUMDes that were able to develop well, making them a motor for the village economy during the COVID-19 pandemic through their various business enterprises. The BUMDes units that have succeeded to grow and develop are those that could identify the local potentials and resources through various innovations, receive social support through their people’s participation and build partnerships with many parties such as the village government, private sector, and the community in the form of collaborative governance.
