The paper presents an early prototype of an online tool named SpeeD, which is aimed at conversion of a recorded speech into the corresponding conceptual database model. SpeeD is the first tool that provides such functionality. The tool is currently able to process English speech and generate the model represented by the corresponding UML class diagram.
Detection of atrial fibrillation (AF) presents one of the main tasks of modern cardiology. In the last few years, the deep learning (DL) emerges as the most frequent approach for accomplishing the task. When deciding to apply DL model for AF detection researchers are facing different choices bringing specific advantages but also imposing specific restrictions. The expansion of publishing, and advancements in this field, demand frequent review of the state of the art. The initial set of 370 papers filtered by keywords of interest, were systematically narrowed to 32 papers in focus. The objective of the paper is to present a comprehensive overview of commonly used ECG databases, signal preprocessing techniques, inputs formatting, DL models used, choice of output classes, and performance metrics achieved.
The end of the 17th and the beginning of the 18th century was marked by radical changes on the demographic map of the Bosnian Eyalet as a serhat of the Ottoman state. In addition to mass migrations of the Muslim population from the lost Ottoman territories towards the interior of the Bosnian Eyalet, there were also continuous movements of the Christian population in the opposite direction. The paper follows the movements of some groups of Christians, mainly those who respond to the bishop's call to settle the desolate areas around Pécs, Szeged, Baja and the surrounding area, but also the migration of other non-Muslim populations towards the Venetian territory, as well as migrations to the „Imperial lands“ due to various political, economic and other factors. While the Venetian government encouraged, with money and investiture, the people to bring families to Dalmatia, and the Austrian government received petitions from the priests of Bosnian monasteries about the difficult situation of Catholics, the Ottoman government throughout that time undertook activities to stop defections, therefore, the paper describes some of the procedures and the situations themselves. Some authors exaggerate when they say that, for example, between 100 and 200 thousand Catholics left Bosnia. The paper shows that according to some reports, 74 thousand Catholics lived in Bosnia before 1683, and 25 thousand half a century later. This is an acceptable number of emigrant Catholics compared to the exaggerations of some chroniclers. An important part of the work is the knowledge obtained from sources, who actually are the non-Muslims that go across the border from the interior and from the borders of the Bosnian Eyalet. Ottoman sources usually refer to both Catholics and Orthodox by the name „kefere“ (a collective noun denoting the non-Muslim population in general). For the Ottoman administration, the most important thing is that it is a category of non-Muslims in order to tax them according to that category. Due to such a situation, it is difficult to give a definitive number of Catholics or Orthodox in a certain period according to Ottoman sources. In the paper, we provide a limited analysis of the case according to some unpublished sources, so it can be seen how many Christians, heads of the household, remained in a certain area. Often, however, it is not possible to know whether they are Orthodox or Catholics, because there are no priests among them. Names are often a problem, too, because patronymics are rare, and names can be tied to a nomenclature common to both Catholicism and Orthodoxy. From the episcopal and friar reports, it can be seen that in that period, the conversion of Muslims also took place, so among the migrants to the north, for example, there were thousands of new Christians. The cities of Požega, Osijek and Brod also lost their Muslim population and hundreds of Catholics from Sarajevo, Kreševo, Modriča and Vrhbosna are coming to them. Registry books record their origin, especially in the first years of the 18th century. The Orthodox and Catholic population from the Herzegovina Sandžak settles mainly in the Boka Kotorska area. An extensive cadastral census from 1701 shows that among the people there are many who come from places that are not affected by war activities. The Orthodox population from Backa and Baranja goes to Slavonia and Srijem, but also to Ottoman territory. On the territory of the Republic of Dubrovnik, war refugees from the Bosnian ejalet are most often Vlachs, especially during the periods of the Moravian War (1684-1699) and the Venetian-Ottoman War (1714-1718). The Ottoman authorities demanded that these people be delivered to them, and the Dubrovnik authorities formally agreed, but they often helped the people to stay there or to go further by sea.

Image segmentation has an important role in image processing and computer vision and it is widely used in numerous applications, including feature extraction, pattern recognition, scene analysis, object tracking. Due to its simplicity and effectiveness, multilevel thresholding approach to image segmentation has gained increased research attention in recent years. In this paper, the ability of two recently proposed metaheuristic algorithms, Honey badger algorithm and Chef-based optimization algorithm to ascertain the optimal threshold values based on Kapur’s entropy is systematically examined. The performance of the two multilevel thresholding image segmentation methods are assessed on a dataset of nine standard benchmark images. Based on a fixed number of independent runs, for each test image and a given number of thresholds, the multilevel thresholding performance is reported using the mean and standard deviation of Kapur’s entropy as well as the best objective function value and the associated threshold values.
Compared to conventional fire detection techniques, high-precision computer vision-based fire detection systems have a number of desirable characteristics, such as the ability to monitor large areas, provide a bountiful amount of information, and are easy to maintain. This paper extensively and systematically investigates the use of simple color-based rules for pixel-wise flame recognition in still images. The rules are evaluated on a hundred and nineteen test images that correspond to fires in urban environments. The performances of the considered flame recognition rules are reported in terms of Recall, Balanced accuracy, Accuracy, F1 score, and Matthews correlation coefficient. The best-performing rule is identified. More complex classifiers are formed by combining two or more simple rules. The experimental results show that simple color-based rules and some of their combinations can offer effective fire recognition performance.
Introduction: Scientists have long searched for the best way to evaluate scientific performance and have come up with numerous indices. Probably, the most famous index is the h-index, a metric that has been used widely in science metrics ever since it appeared. In this study, I evaluated the potential of the new metric Research Interest Score created by ResearchGate (RG). Methods: I analyzed the different metric indices for 88 most cited researchers at the University of Sarajevo. In particular, the number of citations and h-indexes were taken from the Web of Science, Scopus, and Google Scholar databases for these researchers and were correlated with their Research Interest Scores. As a measure of correlation, Pearson correlation coefficients was used. In addition, I conducted a regression analysis to examine how scientometric indices from the Web of Science, Scopus, and Google Scholar predict the Research Interest Score. Results: The Research Interest Score was most strongly correlated with the number of Google Scholar Citations, followed by the Web of Science citations. Interestingly, the Research Interest Score was not highly correlated with any of the h-indexes. The regression model was statistically significant and explained 90% of the variance in the Research Interest Scores predicted by the Web of Science, Scopus, and Google Scholar metric indices. The strongest predictor of the Research Interest Score was the number of Google Scholar citations. Conclusions: The Research Interest Score, a new scientometric measure created by ResearchGate, certainly has a potential to be used as a valid measure of scientific impact.
The aim of our study was to assess the values of hematological profile of Alpine goats in Bosnia and Herzegovina in order to monitor health status of goats; moreover, to determine the effect of age on hematological parameters of goats. A total of 40 apparently healthy Alpine goats included in this study were divided into four groups according to age: <1 year old (Group 1), 1 to 3 years old (Group 2), 3 to 5 years old (Group 3) and >5 years old (Group 4). The following hematological parameters were measured: Red Blood Cell count (RBC), hematocrit (HCT), hemoglobin (HGB), Mean Cell Volume (MCV), Mean Cell Hemoglobin (MCH), Mean Cell Hemoglobin Concentration (MCHC), Reticulocyte count (RETIC), White Blood Cell (WBC), as well as white blood cells differentiation and determination of absolute values white blood cells; platelet count (PLT), and Mean Platelet Volume (MPV). All values investigated in our study were within reference range, except MCHC, percentage of neutrophils and percentage of monocytes. For investigated hematologic parameters, significant (P < 0.05) age-related differences were found for HCT, MCV, MCHC, WBC, lymphocytes and platelet count. Recorded differences might be influenced by undetected infections, genetics, nutrition, fluctuations in the climate or management.
Food safety is a story that unites all civilizations, cultures, and nations, and it is interlaced with various methods for making food safer. Concern for nutritious and safe food is as ancient as humankind itself, and many of the food safety issues that persist today are not new. Diverse records from the ancient world, as well as the religious writings of the three monotheist religions, actually refer to food, its intake, and prohibitions, as well as pathological diseases that may follow from inappropriate intake. Over time, food safety has evolved into a scientific discipline concerned with the handling, preparation, transport, and distribution of food to avoid the transmission of illnesses. The current state of food safety knowledge is the result of past discoveries, innovations, and laws. In modern times, the right to consume safe food is a fundamental human right. It contributes to and promotes sustainable development while supporting the economy, trade, and tourism. Nevertheless, despite significant improvements, we still know relatively little about food-borne illnesses and how infections affect humans.
Abstract The purpose of the paper is to analyse the effects of interpersonal trust in business relations (proxied by trade credit) and institutional trust (proxied by firms’ trust in courts) on firms’ performance. The analysis is performed on a specific sample of 1298 firms in Western Balkan countries which are usually characterized by negative social capital that is considered to hinder economic and social development at all levels. The methodological approach is based on the propensity score matching method and the obtained results show that firms’ perception of courts as fair, impartial and uncorrupted, is connected with lower costs and with positive expectations of an increase in sales in the upcoming period. On the other side, trade credit as a trust variable has a statistically significant and positive effect on firm productivity measured as sales per employee and on expectations of an increase in sales in the upcoming period. The paper contributes to the existing literature in terms of the choice of the post-socialist groups of countries for the analysis, the method that is used (treatment-effects estimation), and in terms of performing firm-level analysis of the effects of two types of trust on selected variables of firm performance.
Purpose. The aim of the paper is to examine whether – and to what extent – the concept of Media and Information Literacy (hereinafter: MIL) can be understood as a possible approach to critical pedagogy in practice by examining the adequacy and comprehensibility of the content of its curriculum, previously adapted to the BiH (Bosnian and Herzegovinian) context and its fragmented education system. Approach/methodology. The first part of the paper presents a brief framework of the concept of critical pedagogy, its relationship with media and information literacy, together with the specifics of the education system of Bosnia and Herzegovina. In the second part, the paper focuses on the case study of pilot training conducted at the Sarajevo Hasan Kikić elementary school, aiming to acquaint teachers and librarians with the concept and curriculum of MIL. Results. Although teachers and librarians have adopted skills to teach about MIL, the results point to a lack of emancipatory pedagogical practices in the existing education system which could counter various, primarily systemically produced forms of oppression. Originality/value. The value of this paper reflects the efforts to read the concept of MIL through the theoretical lenses of critical pedagogy. Although based on the 2011 UNESCO’s understanding of MIL, the originality of this approach also lies in the fact that the conducted workshops were set down on its curriculum adapted to the Bosnian and Herzegovinian context. Practical implications. The practical implications of this research could be seen through the further processes of researching and promoting collaborative teaching and learning, encouraging thus the development of critical thinking, and thinking individuals capable of combating domination and transforming reality through pedagogy. Social implications. Incorporating critical pedagogy while reading the adapted MIL curriculum can be used for promoting a comprehensive and active role of re-creating knowledge, enabling practices of critical attitude towards the existing social reality, and promoting and strengthening democratic practices.
The experience of Eastern European countries indicates that a country cannot simultaneously give up autonomy of monetary and fiscal policy and control of labour mobility without all three causing a reduction in potential GDP at the same time. Namely, if a country opts to peg its currency to the currency of a larger (more developed) country and pursues a restrictive fiscal policy, it will probably 2 lead the workforce to emigrate. This universal rule applies to both developing and developed countries. Nevertheless, the specificity of the developing countries' position is that once the labour force leaves the country, it will almost certainly never return. Therefore, labour mobility should be regarded as entirely different when it takes place between countries at distinct levels of development and when it serves as a mechanism for achieving an external balance between countries at similar income levels. As far as we understand, the just described experience of Eastern European developing countries has not yet been formalized anywhere as economic legality, i.e. trilemma. Thus, this paper can be an introduction to the theory of the impossible trinity of developing countries, explaining the basic concepts, connections between them and open questions.
A hallmark of the development of solid and hematological malignancies is the dysregulation of apoptosis, which leads to an imbalance between cell proliferation, cell survival and death. Halogenated boroxine [K2(B3O3F4OH)] (HB) is a derivative of cyclic anhydride of boronic acid, with reproducible anti‐tumor and anti‐proliferative effects in different cell models. Notably, these changes are observed to be more profound in tumor cells than in normal cells. Here, we investigated the underlying mechanisms through an extensive evaluation of (a) deregulated target genes and (b) their interactions and links with main apoptotic pathway genes upon treatment with an optimized concentration of HB. To provide deeper insights into the mechanism of action of HB, we performed identification, visualization, and pathway association of differentially expressed genes (DEGs) involved in regulation of apoptosis among tumor and non‐tumor cells upon HB treatment. We report that HB at a concentration of 0.2 mg·mL−1 drives tumor cells to apoptosis, whereas non‐tumor cells are not affected. Comparison of DEG profiles, gene interactions and pathway associations suggests that the HB effect and tumor‐‘selectivity’ can be explained by Bax/Bak‐independent mitochondrial depolarization by ROS generation and TRAIL‐like activation, followed by permanent inhibition of NFκB signaling pathway specifically in tumor cells.
