This paper addresses and evaluates approaches to incorporating personality data into a recommender system. Automatic personality recognition is enabled by the LIWC dictionary. Personality-aware pre-filtering techniques are developed and discussed, with the introduced non-targeted stratified personality sampling performing the best. A novel personality-aware model, FFM-SVD, is proposed and shown to outperform alternative models in prediction accuracy.

This paper presents geological characteristic of the deposit Kotezi of the Bugojno coal basin. Regional geological researches were conducted from 1983 to 1987, and detailed from 2014 to the end of 2018. After field research and laboratory tests, the analysis and interpretation of the obtained results was carried out. Based on the determined borders of surface distribution and the research results of the coal deposit Kotezi, proved are four coal layers: II bottom, I bottom, main and roof. Coal of the deposit Kotezi belong to the younger coals, soft to medium hard, no luster (matt), brown to black colored, and have brown streak. Their fracture is plate-like and particleboard. He do not have a distinct lignite structure, except in the lower layers. With their general habitus, they resemble younger brown coals, and belong to humic coals which are relatively low in carbonation. Coal deposit Kotezi is the most important deposit in the Bugojno basin, which is very important due to continuity of coal exploitation. Considering the raw material potential and the possibility of expanding the existing raw material base, the Bugojno coal basin has particular importance for the long-term development of lignite exploitation and its use for thermal energy purposes. Key words: the Bugojno coal basin, Kotezi, coal layers, raw material potential.

Background: Acute gastroenteritis remains an extremely common problem among the general population. In Western countries, an average person will probably face one or two episodes of gastrointestinal infections every year. Objective: The aim of this study was to compare the efficacy of nifuroxazide and probiotic preparation containing lactic acid bacteria in the treatment of acute diarrheal syndrome. Methods: The study was prospective, comparative study. Patients who suffered from acute infective diarrhoea for ≤72 hours and had ≥3 unformed stools per day, with no administration of antibiotics during 10 days before enrolment were divided into two groups: nifuroxazide group and the lactic acid probiotic group. All patients received therapies four times a day for three days. Data was collected at the baseline visit (before the initiation of the treatment) and two follow-up examinations on the third and seventh day from the treatment start. Results: The study included 61 patients, 36 in nifuroxazide group and 25 in probiotic group. Nifuroxazide group compared to probiotic group showed faster improvement of patients’ condition with lower number of stools three and seven days after therapy start (p=0.001 and p<0.001 respectively) and faster stool consistency normalization. On the seventh day from therapy start medium mushy stool consistency was observed in the majority of patients in nifuroxazide group (n=31, 86%) and only in small number of patients in probiotic group (n=5, 20%). Patients were feeling better and there was a trend of reporting better therapy efficacy in nifuroxazide group. Subjective assessment of therapy tolerability was also better in nifuroxazide group. Compliance to therapy and recommended dietary regime was similar between groups and there were no significant differences between groups regarding age, gender, elevated body temperature, abdominal pain, cramps, nausea and vomiting. Conclusion: Although probiotics are sometimes used in the treatment of acute diarrheal syndrome, nifuroxazide has better efficacy and greater patients’ satisfaction. Nifuroxazide can be recommended as the first choice empirical treatment in adult patients with the acute diarrheal syndrome.

The aim of this paper was to analyze the spelling errors of children with dyslexia, in order to determine whether they have a specific pattern of spelling errors or are simply late in acquiring spelling skills. The sample included 30 children with dyslexiaand 30 spelling-level-matched younger children. The research was conducted in the area of Sarajevo Canton and Tuzla Canton in the period from March to May 2022. The results showed that children with dyslexia make similar patterns of errors as spelling-level-matched group. The obtained results show that children with dyslexia in transparent orthography do not have a specific deficit in spelling, but rather delay in acquiring spelling skills. Key words:dyslexia, transparent orthography, spelling errors, specific deficit, delay.

Despite emails having been a standard technology since the 1970s, they are still indispensable in daily communication and the number of sent emails continues to rise year by year. This technology is not limited to business, it is also used in education, entertainment, or personal correspondence. Emails are also present in the everyday life of children: they are required to join websites, social networks or to participate in school -especially in homeschooling. However, emails are also associated with disadvantages such as spam, phishing, or malware. To engage children in security awareness we developed the DigiSkill platform, which provides interactive educational experiences. It consists of modules such as email or browser simulations, to increase the student’s digital skills. In this research, we evaluated the tool with 52 secondary school students to observe their knowledge on security awareness in the context of email usage and to help gain a better understanding. Therefore, we conducted an in-class evaluation with a tool intervention and related pre- and post-activities. We observed different characteristics in emails that students use for classification and identified common misconceptions. We found that students follow an intensely visual approach, which means the visual representation of an email has a strong impact on the level of suspicion students have. We aim to provide educators with a tool to improve the security awareness skills of their students and to discuss educational possibilities in this field with our research findings.

Ensuring safety is of paramount importance in physical human-robot interaction applications. This requires both adherence to safety constraints defined on the system state, as well as guaranteeing compliant behavior of the robot. If the underlying dynamical system is known exactly, the former can be addressed with the help of control barrier functions. The incorporation of elastic actuators in the robot's mechanical design can address the latter requirement. However, this elasticity can increase the complexity of the resulting system, leading to unmodeled dynamics, such that control barrier functions cannot directly ensure safety. In this paper, we mitigate this issue by learning the unknown dynamics using Gaussian process regression. By employing the model in a feedback linearizing control law, the safety conditions resulting from control barrier functions can be robustified to take into account model errors, while remaining feasible. In order to enforce them on-line, we formulate the derived safety conditions in the form of a second-order cone program. We demonstrate our proposed approach with simulations on a two-degree-of-freedom planar robot with elastic joints.

. We obtain a meromorphic continuation of the generalized Tribonacci zeta function to the whole complex plane. The residues of the generalized Tribonacci zeta functions associated to the third-order Jacobsthal, Tribonacci and Narayana sequence at negative inte-ger poles are computed.

The asphalt layer is an important financial part of the total cost of road infrastructure, so it is necessary to analyze and consider all the elements that may affect the quality of the same. One of them is certainly the influence of temperature during the installation of asphalt mass. Namely, neither high nor low temperature of asphalt and the environment are favorable for its installation, so it is necessary to find optimal conditions for the installation of asphalt in order to achieve the best possible results of compaction and cavities in the asphalt layer. The aim of this research is to find the optimal conditions for its installation by comparative analyzes of different temperatures of the asphalt mixture and the environment, in order to obtain the lowest percentage of cavities in the asphalt layer. The legal regulations, ie technical conditions, define the minimum temperature of the asphalt mixture as well as the limit air temperature during the installation of asphalt, but special emphasis is placed on the impact of the temperature of the asphalt installation on the cavities in the asphalt layer. Therefore, the paper observes the optimal temperature of the asphalt mixture so that the smallest possible percentage of cavities in the asphalt layer is obtained. Keywords: asphalt mixture temperature, installation, cavities

In this paper, it was necessary to prove that Semberija is in the geomorphological sense, the southern part of the Pannonian Basin, which is in contact with the Dinaric mountain system. Its done on the basis of the geo- morphological analysis of the terrain, primarily morphotectonic, morphological and morphogenetic similarities with the plain terrain of Pannonia. This was the basis for a complex geomorphological regionalization which included added similarities and connections with the Pannonian Basin in climate, pedogeography and biogeog- raphy sense. Thus, after the complex geomorphological regionalization, it was determined that Semberija is a meso-entity, a subunit of the geomorphological macroregion Sava Basin, ie the southernmost part of the geo- morphological megaregion Pannonian Basin. Key words: Complexed geomorphological regionalization, geomorphological meso-entity Semberija lowland plain, Pannonian Basin, Bosnia and Herzegovina.

Abstract The subject of this paper are the diary no- tes of the Bavarian botanist Otto Sendtner published in the German magazine "Das Ausland" regarding the medieval fortress of Srebrenik and the tradition about its fall under the Ottoman rule, which were completely unknown in the literature. This Munich university professor stayed in the Bosnian ejalet/Province in 1847, and on that occasion, he visited a significant number of cities, starting with Split, Livno and Travnik as the main destination. From the vizier's city and the seat of Ejalet, he went to Bosanska Posavina due to his botanical research, and on that occasion he passed through Srebrenik. Sendtner wrote in detail about the fortress, inspired by its features, and also left a note of local folklore tradition regarding its fall under the Ottomans, which deserves special attention. Also, in Send- tner's exposition, romantic narratives and orientalism ele-ments can be observed in the descriptions of the Srebrenik fortress and the landscape surrounding it, which can be attributed to the features of the imagi- nation about the Middle Ages presented in the European intellectual circles during the middle of the 19th century. Keywords Srebrenik, Bosnia, Middle Ages, oral tradition, travelogue, Otto Sendtner

In the present study, vortex-assisted matrix solid-phase dispersion (VA-MSPD) extraction was used to isolate the major bioactive compounds from H. arenarium. To reduce the negative environmental impact of the conventionally used organic solvents, four different choline chloride-based natural deep eutectic solvents (NADES) were investigated as possible eluents. The most influential VA-MSPD extraction parameters: stationary phase (adsorbent), adsorbent/sample ratio, vortex time, and volume of extraction solvent were systematically optimized. Ultrasound-assisted extraction with 80% MeOH was used as the standard method for the comparison of results. The stability of the obtained extracts was studied over a period of 0 to 60 days at three different temperatures (−18 °C, 4 °C, and 25 °C). All extracts were evaluated both spectrophotometrically (determination of total phenolic content (TPC) and antioxidant activity by ABTS and FRAP assay) and chromatographically (HPLC-UV). NADES based on choline chloride and lactic acid (ChCl-LA) was selected as the most effective extractant, with a determined TPC value of its extract of 38.34 ± 0.09 mg GA/g DW (27% higher than the methanolic VA-MSPD extract) and high antioxidant activity. The content of individual phenolic compounds (chlorogenic acid, dicaffeoylquinic acid isomers, naringenin isomers, and chalcones) in the ChCl-LA extract, determined by HPLC-UV, was comparable to that of the conventionally obtained one. Moreover, the stabilization effect of ChCl-LA was confirmed for the studied compounds: chlorogenic acid, naringenin-4′-O-glucoside, tomoroside A, naringenin-5-O-glucoside, isosalipurposide, and naringenin. The optimum VA-MSPD conditions for the extraction of H. arenarium polyphenols were: florisil/sample ratio of 0.5/1, a vortex time of 2 min, and an elution volume of ChCl-LA of 10 mL.
