Abstract In this chapter, we present a new method of steganography using decomposition of Catalan numbers. The proposed steganographic method consists of two segments: the first segment refers to the process of embedding data and generation of a complex stego key, whereas the second segment refers to the process of extracting a hidden message based on the generated stego key. Both segments consist of several phases. The proposed method provides that the data carrier retains its original shape. At the end of the chapter, security testing and steganalysis of the proposed method are conducted. Implementation in Java programming language successfully proves the work of the proposed method.

The goal of psychometric scaling is the quantification of perceptual experiences, understanding the relationship between an external stimulus, the internal representation and the response. In this paper, we propose a probabilistic framework to fuse the outcome of different psychophysical experimental protocols, namely rating and pairwise comparisons experiments. Such a method can be used for merging existing datasets of subjective nature and for experiments in which both measurements are collected. We analyze and compare the outcomes of both types of experimental protocols in terms of time and accuracy in a set of simulations and experiments with benchmark and real-world image quality assessment datasets, showing the necessity of scaling and the advantages of each protocol and mixing. Although most of our examples focus on image quality assessment, our findings generalize to any other subjective quality-of-experience task.

Bihaćka krajina je, kao sjeverozapadna regija Bosne i Hercegovine, tokom 20. stoljeća bila zahvaćena krupnim historijskim kretanjima koja su u većoj ili manjoj mjeri odredila njenu prošlost. Dio promjena se reflektirao iz ukupnih društveno-političkih, vojnih privrednih i kulturnih tokova bosanskohercegovačke zbilje, dok su neke od njih lokalnog karaktera i ukazuju na osobenosti krajine. Historiografska literatura, nastala u posljednje gotovo dvije decenije, pokazatelj je istraženosti ovog područja u pojedinim bitnim segmentima. U radu je cilj ukazati na historiografsku literaturu i objavljene izvore o Bihaćkoj krajini, s fokusom na periode prijelomnih događaja i procesa koji su obilježili prošlost ovog kraja u 20. stoljeću. U tom smislu je riječ o interesu naučnih i stručnih krugova koji su svoja istraživanja usmjerili na početak 20. stoljeća, odnosno austrougarski period, zatim Drugi svjetski rat i događaje iz socijalističkog razdoblja koji su regiju sjeverozapadne Bosne i Hercegovine doveli u središte pažnje šire javnosti ili zainteresirali historičare. Izdvojena su djela i radovi čiji su autori primarni tematski okvir istraživanja usmjerili na prošlost ovog geografskog područja i istraživanja koja tretiraju širi kontekst bosanskohercegovačke prošlosti, ali u svojim okvirima sadrže značajne podatke za sjeverozapadnu Bosnu. Za ratni period 1992–1995. ukazuje se na dostupne objavljene historijske izvore i memoarske zapise. Razlog izostavljanja literature je pojačan interes za ratnom prošlošću nakon 1990-ih, gdje je došlo do produkcije literature većeg obima koja bi zahtijevala detaljniju historiografsku analizu, što bi činilo zaseban istraživački rad na tu temu.

The inhibition of copper corrosion by Helichrysum italicum extract (HI) in simulated acid rain was investigated using electrochemical techniques. Results indicate an increase in corrosion inhibition efficiency with the HI extract concentration. The inhibitive process was assumed to occur via adsorption of the extract on the metal surface. The thermodynamic data indicated physical adsorption and followed the Freundlich isotherm. The effect of temperature on the copper corrosion was studied. The value of the activation energy confirmed physisorption of extract molecules on the copper surface. The concentration of Cu ions released into solution, measured by atomic absorption spectrometry, was in accordance with the electrochemical results.

Metabolic derangements in Type 2 diabetes mellitus (T2D) are associated primarily with the carbohydrate and lipid levels disturbances. Increased flow of free fatty acids (FFAs) into the blood that is coming from the adipocytes as well as an elevated flux of FFAs from de novo lipid synthesis in the liver contribute to these metabolic disturbances. Previous studies suggested a strong association of the hepatic activity of certain enzymes, such as aspartate and alanine transferase (AST, ALT), gamma glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP) with the progression of T2D. In this study, the potential association of the hepatic activities of the liver enzymes and FFAs levels in T2D was examined. Analysis of the activities of ALT, AST, GGT and AP, as well levels of FFAs, fasting plasma glucose (FPG), and lipid profile was performed in 40 healthy control and 71 diabetic subjects. All participants were free of hepatitis, viral infections or active liver damage. The results showed a positive association between levels of palmitic and oleic acids with ALT activity (p<0.05), while the activity of GGT was significantly associated with the levels of palmitic, stearic, and oleic fatty acids (p<0.01). Interestingly, in control group, a positive correlation was found between palmitoleic acid levels with ALT activity (p<0.05), and a negative correlation palmitoleic acid with ALP activity (p<0.05) was observed. Obtained data suggest that an elevation of free fatty acid levels and the hepatic fat accumulation in insulin-resistant conditions affect the hepatic enzymes activities, which might contribute further to the progression of Type 2 diabetes and its complications.

Debate whether legal persons can be criminally liable has been subject of academic interest and discussions for a long time. Led by Latin phrase “societas delinquere non potest”, the vast majority of legal systems did not accept criminal liability of legal persons for a long time. The key argument for this viewpoint was the lack of „mens rea” element (the “guilty mind” or intention of an individual). Yet, it would be unfair to say that legal persons were not responsible for breach of law in any other way. Legislation of the Former Republic of Yugoslavia recognized economic transgressions as a separate category of criminal offence. After the dissolution of the Former Republic of Yugoslavia, all member states showed commitment to European integration. In order to join the European Union, candidates for future membership had to harmonize national law with “acquis communautaire” and consequently introduced criminal liability of legal persons in criminal and criminal procedure codes. In the paper, besides the historical background, the author analyzes differences and similarities between criminal liability of legal persons in Bosnia and Herzegovina and Croatia, focusing on specific features of criminal proceedings against legal persons. Both countries adopted a model of derived, subjective and cumulative liability. Author compares differences between specific matters of criminal procedure against legal persons. The issue that deserves special attention in the context of derived liability of legal persons is whether a natural person and a legal person can have joint defense. Besides specific features of a criminal procedure against legal persons, the paper also elaborates different regulation of sanctions, security measures and consequences of conviction for against a legal person. Finally, in the conclusion, the author advocates intervention in B&H legislation, following the solutions prescribed by the Law on the Liability of Legal Persons for Criminal Offenses regarding joint and mandatory defense, and, especially, for establishing of a public criminal register of convictions against legal persons.

This paper is the result of a mini empirical research on the duration of judicial and public prosecutorial investigations before the High Court in Novi Sad. A total of 100 cases were analyzed, of which 50 cases from 2008 and 50 cases from 2015 and 2016. The first 50 cases were conducted during the validity of the Criminal Procedure code from 2001, while the other 50 cases were conducted during the validity of the Criminal Procedure Code from 2011. In order for the result to be as comparable as possible, we tried to have the same structure of criminal acts represented in both groupes. The author came to the conclusion that a prosecutorial investigation is not faster than a judicial investigation. The search for the suspect, the search for the injured party, the impediment of the lawer, the strike of the lawers, the preoccupation of the public prosecutor, etc. contributed to the somewhat longer duration of the public prosecutorial investigation.

The paper highlights some of the deterioration of the defendant, s position in the 2011 Code of criminal procedure of Serbia. On the other hand, it points to some relatively new institutions that go behind the traditional role of the defendant, which is reflected in the opposition to the charges. These are three types of defendant, s agreement with the public prosecution. The first form is a diversionary model, which is applied in the pre-trial procedure. The second is the plea agreement. Both forms were introduced before the confluence to relieve criminal justice, but the defendant himself benefits. The third form is the conclusion of an agreement between the defendant and the sentenced person on testimony in other to successfully detect, prove or prevent the criminal acts referred to in article 162, paragraph 1, item 1 of the Code of criminal procedure.

Reason(s) for writing and research problem(s): Bosnia and Herzegovina offers a unique opportunity to examine how education is evolving and adapting in the context of state-building and the extent of efforts made in a still ethnically divided society. It seems very important to examine the role that politics have played in education in Bosnia and Herzegovina throughout history, and the consequences that certain attitudes have had on the current security situation in the country. Aims of the paper (scientific and/or social): This paper aims to determine the consequences of fostering the dominance of politics over education on current relations among citizens in post-conflict Bosnia and Herzegovina, and unveil the impacts of such relations on national security. Methodology/Design: The following methods were used: analytical-synthetic methods, hypothetical-deductive methods, and also axiomatic and comparative methods and, from the data collection perspective, the method of document content analysis, as well as the case study method. Research/paper limitations: The main limitation of this paper is the impossibility to provide a more detailed analysis for the period of 1992-1995. Namely, there are very few available materials that testify to the topic of education in this period. Results/Findings: The results show that all authorities in the observed periods were aware that the ease of their rule and the repetition and maintenance of the ruling relationship depend to a small extent on the character of education. As a result, they carefully selected and prepared curricula and designed educational programs according to their preferences, thus proving the direct impact of politics on education. General conclusion: The impact of politics on education in all three analysed periods of development of education in Bosnia and Herzegovina was confirmed. Given the persistent ethnic polarization, all countries in the region could make fair use of the Council of Europe's expertise, primarily in the areas of human rights, democratic citizenship and cultural diversity. 58 Criminal Justice Issues Year XX, Issue 5, 2020. Halilović-Kibrić – Security Aspects of Fostering the Dominance of Politics Over Education in Bosnia and Herzegovina Research/paper validity: In scientific terms, the research is justified by the need to point out the consequences that the politicized, segregated, fragmented and decentralized education system in Bosnia and Herzegovina has on security issues.
