A QKD network provides an additional security layer for IT-secure cryptographic key distribution that is added to existing conventional networks. Thus, QKD network components must be resilient to security challenges from conventional network environments. This paper provided a novel solution for designing a Key Management System resistant to DoS attacks. Our solution allows applications to function securely in environments with fewer keys. In addition, we have provided approaches for allocating and managing QKD resources to avoid malicious key reservations. Simulation experiments verified the proposed solutions.

Changes in the market, caused by globalization, have led to the fact that many companies needed to adapt their operations. In response to these changes, the concept of supply chain was developed to help companies from procurement to sales of products. This paper examines the effects of supply chains on competitiveness using the example of agro-food companies from the Republic of Croatia. The research was conducted through a questionnaire which included 188 agribusiness companies. The responses were systematized and statistically processed using descriptive statistics, correlation analysis and multivariate regression analysis. The results showed that the effects of supply chains play a major role in determining the competitiveness of agro-food companies. Therefore, it is necessary to improve the effects of the supply chain in these companies in order to improve competitiveness and achieve better results of these companies on the market.

The purpose of this paper is to examine the current state of rural tourism in Republic of Srpska as well as to provide guidance and recommendations for the development of this form of tourism. The used model approach expert opinion and, on this occasion, the DEX method of multicriteria decision-making was used. With this model, an assessment of rural tourist capacities is carried out on a random sample of four tourist facilities. The reason for the results obtained in this way is that the observed facilities have adequately used the natural resources available to Republic of Srpska. In addition, recommendations and guidelines are given in order to further develop this type of tourism in Republic of Srpska. The presented model offers an innovative approach in the assessment of current and potential tourist facilities. For this reason, it should be used in future research.

The aim of the research in the paper is to evaluate the state of rural settlements in Brčko District with regard to the development of rural tourism. Together with the Tourism Department of the Brčko District, five experts from the field of tourism were selected and they evaluated the current state of rural settlements in this part of Bosnia and Herzegovina. The evaluations were processed using the fuzzy approach with the SWARA (Stepwise Weight Assessment Ratio Analysis) multi-criteria decision-making method. Using this method, the weights of the used criteria were determined, representing the degree of development of conditions in rural settlements. The results showed that "rural facilities and services" are the best developed in rural settlements, while the criteria related to feelings and experiences are the least developed. Based on this research, it is possible to implement measures to strengthen certain criteria that have not been adequately developed in order to further improve rural tourism in Brčko District.

Widening case law of the European Court of Human Rights (ECtHR) interpreting the notion of discrimination, especially the ambit of discrimination based on “other status” offers important elements in the understanding of the legal definition of discrimination. More specifically, it offers elements in understanding of the scope of discrimination grounds listed under “other status”, such as the place of residence. Discrimination cases before the ECtHR against Bosnia and Herzegovina relate primarily to the discriminatory nature of Bosnia and Herzegovina’s election system, focusing on ethnicity as the main basis for discrimination. However, often overlooked is the place of residence as the discriminatory ground, identified in numerous cases alongside ethnicity (such as the cases of Pilav, Zornic and recently Pudaric), or as a stand-alone basis as in the case of Baralija. The ECtHR’s positions expressed in judgements to these cases offer certain interpretations important for Bosnia and Herzegovina’s election system, legal and constitutional order and showcase the potential power and influence which the ECtHR’s judgements may have in the strengthening of rule of law and overcoming political stalemates. Outside Bosnia and Herzegovina, the cases may offer some new insights in defining and reinterpreting the legal notion of discrimination and the legal ambit of the prohibition of discrimination on the grounds of place of residence, such as discriminatory effects of legal void and the discriminatory treatment between persons having a place of residence within the same respondent country.

We present an open-source web tool for quality control of distributed imaging studies. To minimize the amount of human time and attention spent reviewing the images, we created a neural network to provide an automatic assessment. This steers reviewers’ attention to potentially problematic cases, reducing the likelihood of missing image quality issues. We test our approach using 5-fold cross validation on a set of 5217 magnetic resonance images.

Various plants have been used in traditional medicine for thousands of years as natural medicines with therapeutic and other pharmacologic effects. Bioactive compounds found in plants, such as flavonoids, trace minerals, essential oils, phenols, glycosides, alkaloids, and tannins, can affect microbial growth, reproduction, and essential cell functions. Plants of the Amaranthaceae family have a broad range of bioactive phytochemical constituents, which provide a variety of medicinal benefits. This review article discusses the characteristics of Amaranthaceae plants that may indicate their use as medicinal plants, especially against infectious diseases. According to the literature, Amaranthaceae plants contain considerable levels of bioactive compounds that make them effective in traditional medicine, even though their impact on numerous microbes has yet to be examined.

Background: Alternative The topic of this article is the development of pharmacy in the Middle Ages. Objective: The aim of this paper is to bring readers closer to the development and importance of pharmacy and health activities in general of this century. Methods: This is sistematic review of the published papers about historical facts about development pharmacy in Bosnia and Herzegovina in the past. Results and Discusion: There are few documents that speak and testify about health and hygiene data and opportunities in Bosnia and Herzegovina from the Middle Ages and the time of the independent Bosnian state, because very little was written and mostly knowledge was transmitted by narrative. Bosnia, as an independent state, was first mentioned in the Charter of Kulin Ban in the 12th century. The Charter was sent to the Republic of Dubrovnik and provided safe passage for merchants through Bosnia and tax exemption. The Republic of Dubrovnik also had many influences on the development of all social conditions, including medicine and pharmacy. Doctors and pharmacists were able to come to Bosnia unhindered and engage in treatment and the sale of medicines, without having to fear whether they would pay taxes to the state or be robbed. Conclusion: Until Bosnia came under Ottoman influence, treatment in Bosnia was rather primitive, the number of pharmacies and health facilities was minimal, and hygienic conditions were rather poor. Folk medicine and spells were mainly practiced, which were passed down from generation to generation, by narrative tradition. Only with the arrival of the Ottomans, hospitals and pharmacies began to open, and the health care system was better regulated.
