: This paper presents the authentication method using the Delaunay triangulation incremental algorithm and the Catalan objects. The proposed method is a combination of computational geometry and cryptography. This method presents a new step towards encoding the triangle coordinates using the Catalan-key. We provided specific suggestions for the application of this method in the authentication for bank clients by the image encryption. Client authentication verification is performed by asking the client to enter the (x,y) coordinate values of randomly selected indices of an array. If the entered coordinates match the index values in the banking system array, then the transaction or other operation is approved. If the matching fails, it means that we have an unidentified person who has followed the whole process and wants to break into the banking system. There are many advantages arising from a scenario for the user authentication by the assigned Catalan object and the stack permutation method. Also, we provided concrete examples for the Delaunay encryption of image with an authentication scenario and experimental results for the proposed method.

The article presents research about the use of genetic algorithms in the analysis of the interrelation among curriculum courses in higher education. The authors used genetic algorithms as a method to analyse the influence that achieved grades in predictors' courses have on achieved grades in dependent courses as well as to observe whether the genetic algorithms can contribute to improving the curriculum. The research was based on a set of data related to the success of students from the Faculty of Information Technologies at the University 'Džemal Bijediae' in Mostar, Bosnia and Herzegovina. The aim was to anticipate students' grades based on the grades they obtained in previous semester's courses. This research should help educational institutions to evaluate the suitability of the sequence of courses within the curriculum in order to enable personalized learning paths, make the teaching processes more efficient, and promote a balanced curriculum. Namely, a good curriculum can attract new students, improve the success rate of enrolled students, and increase the quality and visibility of the institution. Since the genetic algorithm is search techniques for handling complex spaces, we can use it for the research at each stage of the educational process. Analyses of quantitative data using a genetic algorithm can help educational institutions improve the quality of teaching.

Even though the Enterprise Resource Planning (ERP) technologies have been significantly addressed in managerial literature, few studies investigated the effects of digital literacy. This study aims to explore the relationship between digital literacy and ERP technology adoption in Bosnia and Herzegovina (BiH), as well as the mediating effects of business innovativeness within that relationship. A valid and reliable structured survey has been prepared and delivered to companies in BiH which use ERP technologies. Based on the recent literature, first order structural equation model has been proposed and tested. The empirical data was based on 82 questionnaire responses from companies in BiH which use ERP technologies. Once the data has been collected, factory data analysis has been performed to purify scales through items' loadings and Cronbach's Alpha values. The resultant scales have been tested for convergent validity through partial least-square path modelling using Smart PLS 3 software. The results indicated that effects of digital literacy on actual system use are significant and positive, and that business innovativeness partially mediates the relationship.

The security of each system is essential for its use. In order to make this process as successful as possible, it is advisable to develop a threat model for the system under consideration at the design stage. The purpose of the threat model is to enable the identification of security threats, by whose further analysis we can conclude which are the greatest vulnerabilities of the system and which pose the greatest risk. There exist many different approaches to threat modeling in terms of methods, methodologies, and tools. In this paper, we give an overview of those approaches and apply one of them, i.e., the most represented and mature to a specific system. A STRIDE-based methodology, software-centric method, and Microsoft Threat Modeling Tool (MTMT) mixture has been used to threat model the Web of Things (WoT)-based temperature management system which is in the design phase.

The aim of this paper is to analyze the safety of forklift brakes. The research methodology used to analyze forklift brake safety is presented using the checklist descriptive method. The study was conducted on 127 forklifts with an average age of 15 years, where it was found that about 10% of the forklifts did not have a proper parking brake and that about 2% of the forklifts had defective service brakes. Finally, the results obtained from the research on brake safety have been discussed and further research has been proposed.

UDK 94(497.16) "1924" 341.458(=163.4*3)(497.16)"1924" Dana 9 novembra 1924. godine, naoružani Crnogorci pravoslavci su izvrsili napad na selo Sahovici u Crnoj Gori. Povod za ovaj napad bilo je ubistvo Boska Boskovic, nacelnika Kolasinskog okruga 7 novembra 1924. godine. Na njegovi sprovodu iznesena je tvrdnja da su ze njegovo ubistvo odgovorni Bosnjaci muslimani te da je potrebno njega osvetiti. Masakar pocinjen u selu Sahovici 1924. u Crnoj Gori bio je najveci zlocin pocinjen u Kraljevini Jugoslaviji u mirnodopskom periodu. Iako najveci i najbrutaliniji o ovom zlocinu ne postoji puno podataka i svjedocanstva. U ovom clanku navode se, do sad, ne objavljeni dijelovi tekstova iz casopisa „Pravda“ koje govore o zlocinu u Sahovicima i brutalnosti sa kojom je pocinjen. Summary On November the 9th, 1924, armed Montenegrins of the Orthodox Christian faith attacked the village Sahovici in Montenegro. The motive behind this attack was the revenge for the murder of Bosko Boskovic, the Mayor of Kolasin county, on November the 7th 1924. At his funeral the allegations were made stating that Bosniak Muslims were responsible for this murder and that it must be revenged for. The massacre of Sahovici village is the most horrible crime committed in the Kingdom of Yugoslavia in its peacetime period.  Despite this and despite the fact that it was also the most atrocious massive killing we do not have much data or testimonies related to it. In this article we present, until now unpublished pieces of texts from the magazine “Pravda” that relate about this crime and reveal the brutality of the massacre committed in Sahovici village.
