Aim: In addition to clinical knowledge, communication skills and sovereign decision making, a good doctor is also expected to posses Aim: In addition to clinical knowledge, communication skills and sovereign decision making, a good doctor is also expected to posses professional values, including the ability to establish empathic relationships with patients.The purpose of the study was to identify the reasons that lead students to choose the study of dental medicine/medicine, and determine the level of emphaty in relation to the choice of study in the first year students of the Faculty of Medicine in Ljubljana.Methods: For the needs of the research we developed a questionnaire, which included basic data on students, their reasons for choosing the study of medicine or dental medicine and the Jefferson scale of empathy–version for students (JSE-S version with a modified scale with 16 arguments). The questionnaire was forwarded to all 227 first-year students in the academic year 2014/15 at the completion of the Communication course.Results: The study involved a total of 216 (response 95.2 %) students; 158 medical students and 58 students of dental medicine. Among the reasons for enrollment to the Medical Faculty, the highest proportion of medical students indicated a desire to help people (85.3 %), a desire to improve human health (78.8 %) and a desire to work with people (64.7 %); 28.8 % of the medical students chose the argument „because employment is guarantee”, while 14.1 % of medical students believed the argument „because it is well paid“ was the reason to choose the study of medicine.The students of dental medicine most often choose the following answers: a desire to help people (87.9 %), a desire to improve human health (74.1 %), followed by a desire to work with people (65.5 %). The argument “because employment is guaranteed” convinced 50 % of the students, and the argument “because the pay is good” convinced 46.6 %.Three claims were significantly associated with self-assessment of empathic stance: the arguments “because I want to help people” (91.08 ± 10.65 vs. 86.61 ± 12.56; p = 0.037) and »because I want to work with people” (91.82 ± 10.18 vs. 87.90 ± 12.11; p = 0.012) were associated with a greater self-assessmentwhile the argument “because the pay is good” (91.36 ± 11.41 vs. 87.29 ± 9.01; p = 0.023) was associated with a lower self-assessment of empathic stance.Conclusion: Students who want to help people have higher level of self-assessment of empathic stance. The task of a medical faculty is to ensure that students whose choice of study is based on their humanist values are encouraged to have those values further developed and put into practice during their study.

Published: November 2017

Background: Antibiotics are among the most common drugs prescribed in outpatient settings. It is estimated that up to 50 % are prescribed unnecessarily or inappropriately. To plan the actions for optimizing the use of antibiotics, we conducted a national antibiotic consumption study in children aged 0–18 years in the period between 2003 and 2015.Methods: In this national retrospective research we analyzed outpatient antibiotic consumption using ATC/DDD classification. The use of antibiotics was recorded in relation to the pattern of prescription, age, gender and health region.Results: The total consumption of antibiotics decreased by 35 % from 979 to 636 prescriptions per 1000 children/year (PTY) during the whole study period. Te use of all antibiotic classes decreased (except for quinolones and nitrofuran derivatives) by 12.5 %–81 %. In all those years we recorded the highest consumption in children aged 1 to 4 years (2184–1160 PTY). Amoxicillin was the most commonly prescribed antibiotic in children aged 0 to 4 years, penicillin V among 5 to 14 years and co-amoxiclav among adolescents aged 15 to 19 years. In health regions in the northeastern part of Slovenia much more antibiotics were prescribed than in other regions. In 2015, 65 % of prescriptions were prescribed by pediatricians and school medicine specialists, 16 % by physicians without specialization, 14 % by GPs/family doctors and 5 % by other specialists.Conclusions: Despite the decrease in outpatient antibiotic use in children and adolescents in Slovenia, the overall and especially broad-spectrum antibiotic consumption (amoxicillin with clavulanic acid, azithromycin and second/third generation cephalosporins) is still too high. It is necessary to strengthen activities to reduce prescribing, particularly for acute (upper) respiratory tract infections.
Vloga reber pri nastanku in napredovanju idiopatske skolioze
Authors: Gogala Andrej
Published: November 2017

The pathogenesis of idiopathic scoliosis is still a matter of debate as its common cause has not been found. But some basic principles of its onset and progression do exist. The curvature of the spine is always accompanied by rotation of the vertebrae and rib cage. If we want to explain the principles governing scoliosis onset and progression, we should answer some questions. First, why is side curvature of the spine always accompanied by rotation of the rib cage and vertebrae and vertebral rotation is maximal at the curve apex? Second, is structural scoliosis fixed by primary bone growth in growth plates of the vertebrae or by bone remodeling by which bones adapt to external loads? Third, why most of the curvatures are right thoracic? And fourth, what drives the progression of scoliosis? In the theory presented here, attention is given to the role of the ribs. Symmetrical rib cage fixes vertebrae in the midline of the body and prevents rotation of the vertebrae with dual articulating surfaces on each side of the vertebrae. The ribs are connected with intercostal muscles and cannot spread apart on the convex side when the spine bends. Curvature of the spine in the thoracic region is not possible without rotation of the vertebrae and deformation of the ribs. The ribs at the apex of the curve are pulled inwards towards the vertebrae because they are shifted further from the midline than other ribs. With rotation of the vertebrae at the apex of the curve, which are compressed between the ribs, the thoracic circumference diminishes and the tension in the wall is alleviated. The deformation becomes irreversible if new bone growth or resorption and remodeling change shape of the ribs and vertebrae or if ligaments are not firm enough. Bone remodeling is probably more important than primary bone growth in fixing the structural scoliosis. When the rib cage and vertebrae become structurally rotated, vertebrae lose balanced support from the ribs from both sides. Shear forces from the ribs turn vertebrae further and push vertebral bodies toward the convexity. Thus, continuous progression of scoliosis starts.
Characteristics of health behaviours and health status indicators among pregnant women in Slovenia

Published: November 2017

Background: Pregnancy is a period when women reconsider their own health and health related behaviour for the sake of their future child. Along with their health providers, they are faced with a number of risk assessments and decisions, which become far more complex as their effect on two organisms rather than one is at play. This paper provides an overview of possible associations between self-reported health status, health behaviours and socio-demographics during pregnancy.Methods: Study data were obtained from the case-control research project “Analysis of folate metabolism biomarkers in the risk assessment for neural tube defects, orofacial clefts and congenital heart defects”, which recruited participants from May 2013 to September 2015. Questionnaires about maternal health, health related behaviour and socio-demographic characteristics were completed by 450 women. The data include pregnancies from the 1980s to 2015.Results: We observed that younger and less educated women more frequently reported positive smoking status during pregnancy, while higher prevalence of folate/multivitamin supplementation was found among more educated, older and nulliparous women. There was a U-shaped distribution of medication intake (over-the-counter and prescribed) with respect to educational level, with the highest intake in mothers with a masters/PhD degree and among those that completed elementary school. Higher medication usage was also reported among older women. With increasing maternal age there was an increase in medication intake, folate/multivitamin intake, as well as incidence of gestational diabetes over the studied time period, with the highest frequencies occurring in later decades. A higher incidence of chronic diseases was observed in a group of multiparous women than among monoparous women.Conclusions: Considerable socio-demographic disparities exist in health-related behaviour among pregnant women. Improved public health campaigns and individual health care counselling are needed to address specific requirements of socio-demographic groups at higher risks of adverse pregnancy outcomes.

Fermer la parenthèse régionale : retour au municipal !
Authors: Chiasson Guy , Fournis Yann , Mévellec Anne
Published: November 2017

Ce texte interroge la portée d’une série de réformes en matière de développement local et régional annoncées par le gouvernement du Québec depuis l’automne 2014. Ces réformes, hautement critiquées pour avoir supprimé les institutions régionales, impliquent aussi une redéfinition des rôles des municipalités dans le développement des territoires. En s’appuyant sur la littérature sur le monde municipal au Canada, nous testons une double hypothèse voulant que 1) le Québec se soit doté dans les années 1990 et 2000 d’une politique régionale qui s’appuie sur un rôle plus politique des élus, se démarquant ainsi de la fonction traditionnelle des municipalités canadiennes comme pourvoyeuses de services locaux de base et 2) que la série de récentes réformes en matière de développement régional correspond à la fois à une « municipalisation du développement » ainsi qu’à un retour au traditionnel modèle municipal canadien. En conclusion, nous discutons ce triple déplacement du centre de gravité du pouvoir territorial (au profit des municipalités, des élus et des grandes villes) au regard de la restructuration de l’État.
Vers de nouveaux modèles d’action en développement territorial : l’expérimentation à l’échelle locale de la transition vers le « buen vivir »

Published: November 2017

Ce texte porte sur le renouvellement des modèles d’action en développement des territoires en réponse à l’incapacité des politiques publiques de donner une réponse satisfaisante aux besoins et aux aspirations des citoyens et des communautés. Il explore les pistes d’un modèle alternatif au modèle néolibéral à partir de l’analyse de deux expérimentations, celles deParole d’excluEsà Montréal et de Saint-Camille, en Estrie. Ces deux expérimentations mettent en oeuvre un leadership partagé, une gouvernance inclusive et le développement de capacités réflexives basées sur le croisement de savoirs et sur la collaboration entre la recherche et l’action. À travers les expériences menées, nous voyons émerger un modèle qui met en exergue le milieu de vie et non pas la croissance, dans une perspective convergente avec celle de l’approche du bien-vivre (buen vivir).
Numérique, télétravail, développement des territoires ruraux. Analyse et résultats des politiques publiques québécoises
Authors: Scaillerez Arnaud , Tremblay Diane-Gabrielle
Published: November 2017

La situation économique mondiale crée des inégalités territoriales et sociales. En parallèle, le numérique ne cesse de prendre de l’ampleur et peut contribuer à créer de l’emploi, à réduire les écarts sociaux et même territoriaux. Au Québec, de nombreux dispositifs destinés à développer le numérique dans tout le territoire ont été mis en place. Le but est de stimuler l’activité économique et de réduire le chômage. Certains secteurs territoriaux, majoritairement urbains, voire périurbains, tirent leur épingle du jeu. En revanche, les secteurs ruraux les plus éloignés ou les plus proches de grands pôles économiques qui aspirent toute l’activité se retrouvent exclus de cette dynamique. C’est afin de réduire ces écarts territoriaux que le gouvernement québécois a développé différents dispositifs favorisant le déploiement du numérique, y compris dans les zones rurales dévitalisées. Grâce à ce développement technologique, les façons de travailler se diversifient en réponse à la fois au contexte économique (qui incite à une plus grande productivité) et aux attentes des employés désireux de voir s’améliorer la conciliation entre leur travail et leur vie privée. Le travail à distance prend de plus en plus d’importance au Québec et il obtient déjà des résultats significatifs dans certaines régions rurales caractérisées par une perte démographique et une baisse d’attractivité économique. La recherche porte sur neuf municipalités régionales de comté (MRC) québécoises (Les Appalaches, Argenteuil, Arthabaska, Brome-Missisquoi, Charlevoix, Papineau, Les Sources, Témiscamingue et Vaudreuil-Soulanges). Nous avons interrogé des professionnels chargés de l’introduction du numérique ainsi que des professionnels des ressources humaines responsables de l’intégration du télétravail et des nouvelles technologies au sein de ces territoires. L’objet de notre étude est de présenter le dispositif mis en place par le Québec en matière de numérique et de télétravail afin d’en exposer les résultats obtenus au sein de la ruralité.
Identité(s), gouvernance villageoise et développement territorial viable en Kabylie : enquête auprès de la diaspora
Authors: Perret Cécile , Gagnon Christiane
Published: November 2017

Cette recherche tente de problématiser les rapports entre identité(s) – dont l’identité territoriale conçue comme l’une des composantes d’un développement territorial viable –, capital social, territoire, gouvernance et État en Kabylie. À cette fin, 1) nous mettons en évidence les liens entre identité(s) et formes diverses de capital social et 2) nous analysons l’action de l’État et l’action des comités de villages kabyles – qui sont une survivance du mode de gouvernance traditionnel des villages –, pour voir si ces actions, qui représentent deux formes de capital social, sont complémentaires ou substituables. Les résultats d’une enquête originale permettent de proposer un schéma global qui souligne la place de l’identité dans le développement territorial.
Les paradoxes de la transformation d’une association en coopérative de solidarité : le cas de l’Accorderie de Québec
Authors: Michaud Myriam , Audebrand Luc K.
Published: November 2017

Cet article vise à approfondir les connaissances sur les défis et les enjeux complexes des coopératives de solidarité, une configuration multisociétaire qui doit compter au moins deux catégories de membres parmi les suivantes : consommateurs, producteurs, travailleurs et membres de soutien. Bien qu’il s’agisse d’une innovation sociale qui répond aux besoins d’acteurs du développement socioéconomique communautaire, la coopérative de solidarité reste, à ce jour, peu étudiée. Afin d’améliorer notre compréhension de ce modèle d’entreprise, nous étudions le cas de l’Accorderie de Québec, qui a entrepris un processus de transformation, passant d’une structure associative (OBNL) à une structure de coopérative multisociétaire (coopérative de solidarité). Notre étude de cas nous conduit à mettre en évidence certains paradoxes vécus dans cette coopérative de solidarité, contribuant ainsi à enrichir les connaissances des enjeux entourant cette nouvelle forme organisationnelle.
Quand les religieuses vieillissent en territoire séculier : la vie communautaire à l’épreuve de l’âge
Authors: Amiotte-Suchet Laurent , Anchisi Annick
Published: November 2017

En Suisse comme en France, les communautés catholiques apostoliques de religieuses vieillissent. Lorsque le grand âge affecte l’autonomie des membres des congrégations, le recours à des professionnelles des soins est indispensable. Notre article se base sur une étude sociologique menée en Suisse et en France qui analyse la transformation de couvents de religieuses catholiques en maisons de retraite. Ces transformations nécessitent des arrangements quotidiens entre les religieuses et les équipes de soins. Mais ce pragmatisme des acteurs en présence, visant à maintenir entre eux des bonnes relations, implique une renégociation du niveau d’exigence de la vie religieuse communautaire.
Le vieillissement des électeurs communistes à l’épreuve des vicissitudes du communisme municipal
Authors: Gouard David
Published: November 2017

Le comportement électoral des anciens électeurs communistes au sein des quartiers populaires a souvent fait l’objet de controverses. Si une partie des recherches insistent sur la fidélité électorale qui continue de caractériser les générations ouvrières, d’autres recherches pointent au contraire la croissance de l’abstention et la progression du vote d’extrême-droite au sein de ces groupes sociaux. Cet article se donne précisément pour objectif d’interroger la diversité des trajectoires sociopolitiques des personnes âgées qui apportaient autrefois régulièrement leur soutien électoral en faveur des candidats communistes. Cette étude se fonde sur une enquête monographique et comparative de deux anciens quartiers ouvriéro-communistes de la région parisienne qui ont, depuis les années 80, connu des trajectoires sociales et politiques nettement contrastées. L’essentiel des matériaux d’enquête repose sur des questionnaires recueillis à la sortie des bureaux de vote, des entretiens et des observations. La comparaison des deux quartiers fait apparaître deux grands modèles de vieillissement. Dans le premier quartier, là où le fait communiste s’est largement émoussé, les populations âgées évoluent dans une forme d’anomie sociale et politique qui tend à nourrir la désaffiliation électorale à l’égard de l’ancien ordre politique local. À l’inverse, la revalorisation symbolique de l’autre quartier, là où les descendants de l’ancienne « aristocratie politique » locale se sont majoritairement installés, participe au maintien d’une cohésion intergénérationnelle et intragénérationnelle favorable à la fois à l’exercice de la citoyenneté à l’échelle locale, mais également au maintien d’une loyauté aux candidats communistes.
L’Église et l’État, de Taschereau à Duplessis : mythes et constructions historiques
Authors: Dumas Alexandre
Published: November 2017

La recherche sur les relations entre l’Église catholique et l’État québécois à l’époque de Maurice Duplessis est, à ce jour, encore embryonnaire. Maintes perceptions contemporaines ont été élevées au rang de réalités historiques sans que des recherches aient d’abord été menées. À défaut d’avoir accès aux sources, nous avons accepté les récits contestés de Robert Rumilly et de Conrad Black lorsqu’ils présentaient une certaine vision de la réalité conforme à nos préjugés. C’est notamment le cas en ce qui concerne l’opposition du clergé à Louis-Alexandre Taschereau, son soutien à Maurice Duplessis et l’entente supposée entre l’Union nationale et l’épiscopat. Le présent article vise à faire le bilan historiographique de cette question.
L’« État français » sans la jeunesse : Lionel Groulx et la Révolution tranquille
Authors: Bédard Éric
Published: November 2017

Dès les années 1920, Lionel Groulx et l’équipe de L’Action française avaient espéré qu’un jour l’État du Québec travaillerait à l’émancipation économique et politique des Canadiens français. Au moment où ce programme semble prendre forme, grâce aux actions du gouvernement de Jean Lesage, le penseur du traditionalisme canadien-français se montre pourtant très critique. Les transformations culturelles en train de s’opérer le rendent en effet très pessimiste. Le regard désenchanté de Groulx ne tient pas seulement au processus de laïcisation, mais aussi à la représentation qu’il s’est toujours faite de la jeunesse. Or celle des années 1960 l’inquiète au plus haut point.

We describe the architecture and organization of ubiquitous health monitoring systems, Body Sensor Networks, and integration of wearable and environmental sensors. We also describe mainstream mobile health related applications in today’s mobile marketplaces such as Apple App Store and Google Android Marketplace. Finally, we present the development of UAHealth - our integrated mobile health monitoring system for wellness management, designed to monitor physical activity, weight, and heart activity.
The Usage of Information Technology in the Implementation of the Bologna Principle of the Student Mobility
Authors: Radić Gordana
Published: November 2017

In this paper, student mobility is observed as one of the steps in realization of the Digital Agenda of the European Union. Student mobility, as one of the main principles of the Bologna process, is the means of effectiveness increase and quality of the educational system in European Higher Education Area, EHEA, because it enables better exchange and flow of knowledge and ideas, as well as the adoption of good practices. Management Identity (IdM) system of the Higher Educational institution is a system which supports student mobility by using personal information when accessing data. The basic identity document in this system is a student smart card with the owner’s fingerprint. This biometrical data insures high level of data and identity protection. This paper proposes informational system which, in itself, contains standards for student mobility support as one of the modules of the IdM system of the Higher Educational institution.
Model for Managing Software Development Projects by Fixing Some of the Six Project Management Constraints
Authors: Todorović Boris , Matić Miroslav
Published: November 2017

This study is focused on the software development process, viewed from perspective of information technology project manager. Main goal of this research is to identify challenges in managing such projects and provide a model for delivering software solutions that satisfies client’s expectations. Project management theory describes six constraints or variables in every project, which project managers can use to better control the project and its outputs. Fixing some of the six project management constraints (scope, cost, time, risks, resources or quality) will allow project manager to focus on most important project aspects, rather than being drawn between all of the variables.This paper is aimed at information technology project managers and portfolio managers, as it describes the practical application of this model on a software development project. Findings of this research support the theory that, by applying good project management practice and focusing on project/business-critical requirements, will enable project managers to complete projects successfully and within tolerance limits. Results show that by identifying key business constraints, project managers can create good balance of six constraints and focus on the most important ones, while allowing other constraints to move between limits imposed by clients and stakeholders.

Published: November 2017

In this paper we will give a literature review related to game-based education, in the first place at university, as well as the analysis of existing solutions which should enable this type of eLearning. The main topic of this research will be capacity for applying modern information technologies for developing game-based learning platform. When we chose this topic, we started form the fact that there are no applied game-based eLearning systems at universities. During analysis phase, we found that more research is needed in order to improve application of games in education. In the first place, these studies should cover listed problems: how to design educative games in order to achieve better learning effects; how to develop software tools to automate educative game development process; establish methods and techniques for knowledge and skills assessment utilizing educative games.

Published: November 2017

Users today expect email and instant messaging access, surf, video games and other services through mobile broadband access networks. In order to support this increasing data traffic, advanced resource management has to be implemented. As CAC (Call Admission Control) algorithm plays an important role in this resource management, comparing of two proposed call admission control algorithms has been done in this paper. Algorithms are tested in simulation environment, for two different periods of time. They showed expected characteristics in both 1000 and 10000 seconds periods, and newly proposed DG CAC algorithm showed better results than other algorithm, in number of handover requests, and in the way of returning resources to degraded connections.
Comparable Evaluation of Contemporary Corpus-Based and Knowledge-Based Semantic Similarity Measures of Short Texts
Authors: Furlan Bojan , Sivački Vladimir , Jovanović Davor , Nikolić Boško
Published: November 2017

This paper presents methods for measuring the semantic similarity of texts, where we evaluated different approaches based on existing similarity measures. On one side word similarity was calculated by processing large text corpuses and on the other, commonsense knowledgebase was used. Given that a large fraction of the information available today, on the Web and elsewhere, consists of short text snippets (e.g. abstracts of scientific documents, image captions or product descriptions), where commonsense knowledge has an important role, in this paper we focus on computing the similarity between two sentences or two short paragraphs by extending existing measures with information from the ConceptNet knowledgebase. On the other hand, an extensive research has been done in the field of corpus-based semantic similarity, so we also evaluated existing solutions by imposing some modifications. Through experiments performed on a paraphrase data set, we demonstrate that some of proposed approaches can improve the semantic similarity measurement of short text.
Digital Signal Processing Applications with Iterative Logarithmic Multipliers
Authors: Avramović Aleksej , Bulić Patricio , Babić Zdenka
Published: November 2017

Many digital signal processing applications demand a huge number of multiplications, which are time, power and area consuming. But input data is often corrupted with noise, which means that a few least significant bits do not carry usable information and do not need to be processed. Therefore, approximate multiplication does not affect application efficiency when approximation error is less than noise introduced during data acquisition. This fact enables usage of faster and less power-consuming algorithms that is important in many cases where processing includes convolution, integral transformations, distance computations etc. This paper discusses logarithm-based approximate multipliers and squarers, their characteristics and digital signal processing applications based on approximate multiplications. Our iterative multipliers and squarers contain arbitrary series of basic blocks that involves only adders and shifters; therefore, it is not power and time consuming and enables achieving arbitrary accuracy. It was shown that proposed approximate multipliers and squarers can be used in several signal processing applications without decreasing of application efficiency.
Functional Dependencies Analyse in Fuzzy Relational Database Models
Authors: Vučetić Miljan
Published: November 2017

This paper presents a literature overview of Fuzzy Relational Database Models with emphasis on the role of functional dependencies in logical designing and modeling. The aim is the analysis of recent results in this field. Fuzzy set theory is widely applied for the classical relational database extensions resulting in numerous contributions. This is because fuzzy sets and fuzzy logic are powerful tool for manilupating imprecise and uncertain information. A significant body of research in efficient designing FRDM has been developed over the last decades. Knowing the set of functional dependencies, database managers have a chance to normalize the same eliminating redundancy and data anomalies. In this paper we have considered the most important results in this field.
Mutation Testing: Object-Oriented Mutation and Testing Tools
Authors: Ivanković Z. , Markoski B. , Radosav D.
Published: November 2017

Software testing represents activity in detecting software failures. Mutation testing represents a way to test a test. The basic idea of mutation testing is to seed lots of artificial defects into the program, test all defects individually, focus on those mutations that are not detected, and, finally, improve the test suite until it finds all mutations. Mutants can be created by mutating the grammar and then generating strings, or by mutating values during a production. Object-oriented (OO) programming features changed the requirements for mutation testing. Non object-oriented mutation systems make mutations of expressions, variables and statements, but do not mutate type and component declarations. OO programs are composed of user-defined data types (classes) and references to the user-defined types. It is very likely that user-defined components contain many defects such as mutual dependency between members/classes, inconsistencies or conflicts between the components developed by different programmers. Class Mutation is a mutation technique for OO programs which particularly targets plausible faults that are likely to occur due to features in OO programming. Mutation testing requires automated testing tools, which is not a trivial tool to make. Automated mutation tools must be able to parse the program and know its language. When the program is run, mutant can be killed by one of two possible scenarios: if a mutant crashes, or if the mutant goes into an infinite loop.
Comparative Implementation Analysis of AES Algorithm
Authors: Damjanović Boris , Simić Dejan
Published: November 2017

Advanced Encryption Standard (AES) is the first cryptographic standard aroused as a result of public competition that was established by U.S. National Institute of Standards and Technology. Standard can theoretically be divided into three cryptographic algorithms: AES-128, AES-192 and AES-256. This paper represents a study which compares performance of well known cryptographic packages - Oracle/Sun and Bouncy Castle implementations in relation to our own small and specialized implementations of AES algorithm. The paper aims to determine advantages between the two well known implementations, if any, as well as to ascertain what benefits we could derive if our own implementation was developed. Having compared the well known implementations, our evaluation results show that Bouncy Castle and Oracle/SUN gave pretty equal performance results - Bouncy Castle has produced slightly better results than Oracle/Sun during encryption, while in decryption, the results prove that Oracle/Sun implementation has been slightly faster. It should be noted that the results presented in this study will show some advantages of our own specialized implementations related not only to algorithm speed, but also to possibilities for further analysis of the algorithm.

Authors: Milenković Ivan , Latinović Olja , Simić Dejan
Published: November 2017

Abstract: Today, identity management systems are widely used in different types of organizations, from academic and government institutions to large enterprises. An important feature of identity management systems is the Single Sign-On functionality. Single Sign-On allows users to authenticate once, and freely use all services and resources available to them afterwards. In this paper, we present the usage of Kerberos in identity management systems. An overview of Kerberos protocol, state of the art of identity management systems and different generic architectures for identity management is given in the paper. Also, we present a Single Sign-On identity management architecture proposal based on Kerberos protocol, and discuss its properties. Special attention was given to authentication, authorization and auditing.

Selection of Telecommunication Access Networks
Authors: Katanić Predrag
Published: November 2017

Abstract: The development of Internet technology and computer networks leads to the convergence of traditional systems voice, video and data into a unique IP-based TriplePlay system. Differences in implementing TriplePlay service basically come down to the choice of technology of data transmission from the last aggregation point (node) to a subscriber (Last Mile). Analyzing Internet market, the Organization for Economic Co-operation and Development (OECD) made trend in increasing demand for bandwidth during the period from 2007 to 2017. The analysis is based on SmartHome concept which includes broadband internet as well as multimedia services such as IPTV, cell phones and so on. The results of the analysis to a great extent confirm increasing trend of the consumers’ demand for bandwidth defined by Jakob Nielsen. His theory is based on the previous period and predicts that the need for bandwidth will rise by 50% every year. Nielsen’s diagram resembles that of Moore which predicts that CPU power will double every 18 months, that is 67% a year. The constant alterations in market and technology causes dilemma to operators in terms of investment. It is quite difficult to answer the question about the choice of technology of connecting the subscribers from the aspect of both technological and economic justification. Finding the answer to this question is the main goal of this paper.

Abstract: An increasing number of services and facilities that are of interest to users is based on video streaming. Technical characteristics of video have a strong impact on the quality of a video streaming service and its perception by users. The most important measure of quality, which focuses on the user, is the Quality of Experience (QoE). Given that video advertising is a typical video streaming application, it is necessary to analyze the effect of the change of video characteristics on the QoE. This paper examines the impact of resolution and frame rate change on the QoE level by using objective and subjective QoE metrics. It also looks at the possibility of mapping the objective QoE metrics into subjective ones, if the QoE in Internet video advertising is analyzed. It was demonstrated that the values obtained by the objective assessment of quality can be mapped to the results obtained by subjective assessment of quality when the quality of experience of linear in- stream video ads is analyzed. The results indicate that temporal aspects of video quality assessment, e.g. influence of resolution and frame rate change to the level of the QoE, can be achieved by implementation of objective methods. Therefore, quality of experience can be improved by the proper selection of video characteristics values.

Published: November 2017

Chief Executive Officer (CEO) selection as a subset of personnel selection asks for different characteristic compared to a selection of other personnel. The reason for this is the polymorphic nature of the CEO role. The complexity and importance of the selection problem, call for analytical methods rather than decisions based on intuition. The multi-criteria nature and the presence of both qualitative and quantitative factors make the entire selection more complex. As such, the CEO selection is a multi-criteria decision making problem decision making problem, affected by several qualitative and quantitative, often conflicting criteria which are usually uncertain. This paper proposes a CEO selection approach based on the fuzzy decision support system developed by using JAVA technology and extent analysis method. This system is applied in a real-life case study to evaluate the most suitable person for a CEO position in information and communication (ICT) company dealing with the rating of both qualitative and quantitative criteria, and testing appropriate consistency to ensure quality of selection.

Published: November 2017

This paper presents the time complexity analysis of the Binary Tree Roll algorithm. The time complexity is analyzed theoretically and the results are then confirmed empirically. The theoretical analysis consists of finding recurrence relations for the time complexity, and solving them using various methods. The empirical analysis consists of exhaustively testing all trees with given numbers of nodes  and counting the minimum and maximum steps necessary to complete the roll algorithm. The time complexity is shown, both theoretically and empirically, to be linear in the best case and quadratic in the worst case, whereas its average case is shown to be dominantly linear for trees with a relatively small number of nodes and dominantly quadratic otherwise.

Published: November 2017

The IT function became the backbone of the company and the central driving force of the entire operations of an organization. Modern electronic commerce is very dependent on the quality of information system supported with information technology. Safety aspects of business and electronic transactions transfer (Internet-supported), particularly in the banking sector, require a more complex audit of the organization, both financial and the information system audit. This paper presents the basic and in practice most frequently applied standards and guidelines for checking of security controls in information systems. The work presents the COBIT and ITIL as the two most prevalent methodologies for quality audit of information systems with the presentation of two ISO 27000 series of standards on information security.
Comparison of Perceived Interactivity Measures of Actual Websites Interactivity
Authors: Štavljanin Velimir , Jevremović Milica
Published: November 2017

Interactivity is a concept of enormous importance for digital marketing. It was recognized as a key feature of website, a hub of all digital marketing activities. But, almost all interactivity measures were conceptualized one or two decades ago. In the meantime, technological novelties changed the face of websites. Also, a number of interactivity features increased exponentially. Those changes had a huge impact on practice and could influence user’s perception of interactivity. Aim of this paper is to explore whether several selected existing measures of perceived interactivity could cope with those changes. Paper reports a study in which two websites of low and high interactivity were developed and in an experimental setting as stimuli used to test three perceived interactivity measures. Results show that all measures estimated perceived interactivity of a high interactivity website better than of a low interactivity website. Also, results show that particular dimensions of a model could be used to estimate overall interactivity.

Authors are continuing to analyze factors which influence on three food essential elements: food safety, food security and food quality. There are discus about innovation in food technology, nanotechnologies, and food packaging. Novel sensing technologies using bio or nano materials can be used to detect quality and safety attributes in packaged foods. These sensing technologies range from rapid non-destructive and non-contact to highly specialized micro and nano-biosensing structures. In addition, the authors analyze the latest research on the application of biosensors to measure parameters that affect the safety and quality of products.Future priorities for research in food science should build on the existing knowledge base and extend the impact of basic and strategic research in delivering high quality foods and food products and improving human health.
