Dear authors, readers and future authors,it is my pleasure to present you the 1st number of the 38th volume of the Journal of Information and Organizational Sciences – JIOS.Please allow me one personal note. This is my last issue as an editor. I started in 2008. and it is time to make some changes. I’ll continue to act as a member of editorial board but I am handling over my editorial duty to new editor Alen Lovrenčić. It was pleasure to work with all authors, reviewers and collaborators and please continue partnership with JIOS because we have high aims which cannot be achieved without dedicated scientific community. I would also like to thank the publishing team of JIOS who helped with many operational issues especially: Bernarda Kos, Goran Hajdin and Darko Grabar. In this issue a selection of 3 original scientific papers, 1 survey paper and 1 preliminary communications has been included, all of which have undergone a rigorous double-blind review process in some cases in several rounds.The constant mission of JIOS is to cover scientific publications from broad area of information sciences and related disciplines and we continuously receive many articles in which authors strive to achieve scientific merit. Our review procedure is very strict but even when we decline papers we try to encourage authors in their future work and motivate them to give better results. That is why we maintain very good relations with our authors and we invite all of you to extend cooperation with JIOS.We hope that the variety of themes will draw the attention of researchers in different fields of information sciences and motivate potential authors to expand the Journal’s thematic scope by other themes that may be of interest to the wider ICT research community. These themes motivate us to continue our work of delivering research results to interested audience. The ICT field is changing rapidly and we are constantly searching for cutting edge articles that open perspective and motivate further research. We have to notice that future of ICT related research is in interdisciplinary approach and relations with other research domains which is highly emphasized in Horizon 2020 directions and all related project lines. That is why we encourage and promote scientific collaboration across scientific areas that will bring us new interesting articles. We hope that many of you who will read the Journal will join us as authors, readers and reviewers and help us to fulfill our mission. The number of submitted papers increases every year giving us opportunity to increase the quality and visibility of JIOS.I would like to use this opportunity to encourage prospective authors among you, dear readers, to submit papers at http://jios.foi.hr. You are also invited to share with us your comments or critical remarks regarding the papers previously published in the Journal. Further, we would appreciate your willingness to become a reviewer for submitted papers and thus contribute significantly to the rising quality of JIOS.So far JIOS has been indexed in ten well known databases. We are continuously investing a lot of effort to extend the list of databases where JIOS would be cited, in order to make the published papers available to a larger readers’ audience, and give your research a greater impact factor.So please be with us in the future, support new editorial team and help us build JIOS together.Neven VrčekEditor

Biometric systems play an important role in digital investigation process as a important factor of authentication and verification applications, since they are strongly linked to the holder of a biometric  traits  and  possible  suspect.  Thus  it  is  important  that  biometric  systems  can  be designed  to  withstand  attacks  when  employed  in  security-critical  applications,  especially  in unattended  remote  applications  such  as  energy  plants,  access  to  borders  at  airports,  ecommerce  etc.  Biometric  recognition  either  raises  important  legal  issues  of  remediation, authority,  and  reliability,  and,  of  course,  privacy.  The  standard  assumptions  of  the technologists  who  design  new  techniques,  capabilities,  and  systems  are  very  different  from those embedded in the legal  system.  Legal precedent on the  use of biometric technology is growing, with some key cases going back decades and other more recent cases having raised serious questions about the admissibility of biometric evidence in court. In this paper authors is about to explain influence of reliability of biometric system on general acceptance of digital evidence  in  Court  of  Justice  process.  Through  paper  authors  are  also  about  to  propose vulnerability assessment of biometric system as improvementfactor of reliability of existing methodology  for  preserving  chain  of  custody  of  digital  evidence  called  DEMF  (Digital Evidence Management Framework).

Each organization should be aiming at higher efficiency. Government institutions should not make  an exception.Business  processes of  today’s  government  institutions  are extremely influenced  by  modern  ICT and  user  acceptance  plays  a  pivotal  role  in  success  of  all ICT projects. As  government  tends  to  design  and  launch  online  services  without  actually measuring citizens’ needs, understanding citizens’ (taxpayers’) needs is becoming crucial for government institutions.In this paper, a range of earlier studies have been critically analyzed and comparedto provide anintegrated model that can identify factors which could influence adoption of e-government services. The  goal of this article is to  study citizens’ demand for different  levels  of  electronic  government  service and to find  factors  which  influence  the adoption ofthese same services.This study integrates variables from technology acceptance model  (TAM)  and  trustworthiness  model.Analysis  of  the  results  indicates  that  there  is a significant  positive  relationship  between  Trust  in  Internet,  Perceived  usefulness, Perceived ease of use andtheIntentionto use. Implications for further research are discussed.

This review focuses on identifying how the literature studies the existing problems in the Resource Representation (RR) of Institutional Repositories (IR). RR is a process of recording in a persistent manner a set of data (metadata) as a synthesis and replacement of the "real" object, to allow its identification, retrieval and dissemination. RR is defined by certain elements: resources, metadata schema, storage and cataloging. On the other hand, IRs are based on functional processes according to the material that is deposited and the ISO 14.721 standard: ingest, storage, cataloging,indexing, search engine and browsing. The results of this review show that identifying the problems found in these elements and functional processes is not a subject of study for the researchers, which leads to a vacant area in this field, and in this way to solve some of the problems present in the RI, from the point of view of functional elements and processes.

Nowadays, there has been an increasing application of pruning robots for planted forests due to the growing concern on the efficiency and safety issues. Power consumption and working time of agricultural machines have become important issues due to the high value of energy in modern world. In this study, different multi-layer back-propagation networks were utilized for mapping the complex and highly interactive of pruning process parameters and to predict power consumption and cutting time of a force control equipped robotic pruning machine by knowing input parameters such as: rotation speed, stalk diameter, and sensitivity coefficient. Results showed significant effects of all input parameters on output parameters except rotational speed on cutting time. Therefore, for reducing the wear of cutting system, a less rotational speed in every sensitivity coefficient should be selected.

In this paper we describe possible interpretation and reduction of fuzzy attributes in GeneralizedOne-sided Concept Lattices (GOSCL). This type of concept lattices represent generalization ofFormal Concept Analysis (FCA) suitable for analysis of datatables with different types of attributes. FCA as well as generalized one-sided concept lattices represent conceptual data miningmethods. With growing number of attributes the interpretation of fuzzy subsets may become unclear, hence another interpretation of this fuzzy attribute subsets can be valuable. The originalityof the presented method is based on the usage of one-sided concept lattices derived from submodels of former object-attribute model by grouping attributes with the same truth value structure.This leads to new method for attribute reduction in GOSCL environment.

The issue of natural and social science courses in high schools, as well as in grammar schools, is  very important not only on a global level. Therefore, the aim of this study is to address the issue of improving the process of learning with an emphasis on those subjects which students of a certain program find difficult.By means of its application in teaching, multimedia – being a combination of various media – has enabled the introduction of new channels in the information transfer process, i.e. the reception of information through multiple sensors. At the same time the mentioned fact represents the advantage of multimedia materials over classical textual materials.The research was conducted on the sample of 121 students, namely two social science classes (62 students) and two natural science classes (59 students). Ultimately, the result of the study is the quantification of the effect of multimedia on various student groups, as well as the recognition of differences when it comes to subject preferences, learning styles and attitudes towards learning.

Dear authors, readers and future authors,it is my pleasure to present you the 1st number of the 37th volume of the Journal of Information and Organizational Sciences – JIOS.In this issue a selection of 3 original scientific papers, 1 preliminary communication and 1 survey paper has been included, all of which have undergone a rigorous double-blind review process in some cases in several rounds.As in prior issues of the Journal, this one also comprises papers that cover broad themes from various ICT fields and related areas: software engineering, strategic planning of information systems, knowledge management and quantum computing. We hope that the variety of themes will draw the attention of researchers in different fields of information sciences and motivate potential authors to expand the Journal’s thematic scope by other themes that may be of interest to the wider ICT research community. These themes motivate us to continue our work of delivering research results to interested audience. The ICT field is changing rapidly and we are constantly searching for cutting edge articles that open perspective and motivate further research. We have to notice that future of ICT related research is in interdisciplinary approach and relations with other research domains which is highly emphasized in Horizon 2020 directions. That is why we encourage and promote scientific collaboration across scientific areas that will bring us new interesting articles. We hope that many of you who will read the Journal will join us as authors, readers and reviewers and help us to fulfill our mission. The number of submitted papers increases every year giving us opportunity to increase the quality and visibility of JIOS.I would like to use this opportunity to encourage prospective authors among you, dear readers, to submit papers at http://jios.foi.hr. You are also invited to share with us your comments or critical remarks regarding the papers previously published in the Journal. Further, we would appreciate your willingness to become a reviewer for submitted papers and thus contribute significantly to the rising quality of JIOS.So far JIOS has been indexed in nine well known databases. We are continuously investing a lot of effort to extend the list of databases where JIOS would be cited, in order to make the published papers available to a larger readers’ audience, and give your research a greater impact factor.

Technology parks provide infrastructure for the creation and developmentof knowledge-based organizations, which are associated with centers oftechnological excellence, mainly universities. This research addresses thequestion of management and skills acquisition in member organizations oftechnology parks in Slovenia. As means and lever for development organizations,we recognize the values and organizational culture, which cannot be achievedwithout employees who possess good knowledge. We associated knowledgemanagement with employee turnover factor. The central purpose of this researchis to focus on exploring the impact of movements in knowledge management on theturnover in organizations, which are members of technology parks. By usingmultivariate regression methods we confirmed that the required skills,knowledge acquisition and knowledge transfer channels, have a statisticallysignificant effect on employee turnover in technology parks.

Aspect-oriented programming has been introduced in order to increase the modularity of object-oriented programs and is claimed to improve software quality. Although there are various researches on this claim, the question to what extent aspect-oriented programming improves the quality of programs depending on a developer’s experience still remains. The purpose of this study is to investigate whether aspect-oriented programming used by novice programmers improves the quality of programs, in terms of software flexibility and readability (consequently reusability and maintainability as well). As a part of an undergraduate course in programming paradigms and languages, a systematic comparison between students’ object-oriented and aspect-oriented solutions of the same problem was driven. In order to drive this comparison we have established the basis for the development of the new quality assessment model consisting of software metrics for an objective evaluation and student survey for subjective evaluation. The results show that the use of aspect-oriented programming lead to novices’ programs that are easier to change and read (flexible and readable) compared to object-oriented programs. What is more, administered survey showed that students perceive their programs as more flexible and readable.

The SPIS methodology provides methods and techniques of developing an information system (IS) that would correspond with the requirements of an organization. The result of its application is the strategic plan of IS development that would meet the future needs. As is the case in the methodology of the strategic planning in general, the primary drawback to the strategic planning of the information system is the lack of efficient control of implementation of the strategic plan, and this is precisely what this research paper deals with. One of the procedures in the measuring of results of an organization, which is also recommended by the SPIS, is the Balanced Scorecard methodology (BSC). However, the BSC concept which the classic SPIS methodology recommends as suitable for the evaluation of performance of the information technology (IT) on the business system and the performance of that new business system, does not take into account the constraint that may lead to non-implementation of the planned activities. Furthermore, the BSC has been criticised for the oversimplified modelling of the cause-consequence relations that do not take into account the time delay and the feedback.This paper provides results of the research that resulted in identification of two types of constraints that need to be included when determining the optimal IS/IT strategy. Within the context of the system dynamics (SD) approach, the broadening of the problem with the analysis of the strategy implementation dynamics results in the new practical knowledge about the control over the time-dependant values and, consequently, with a proposal that would eliminate the reasons for the abovementioned criticism.

The Quantum game theory is an extension of the classical game theory which describes games in which players share quantum information during the game. The use of the quantum mechanical effects enables players’ better results than they would achieve in the classical game without sharing any information at all. In this paper I would like to describe a new two player cooperative game which is based on the well known CHSH game. A quantum strategy for a new game will be introduced and it will be compared to the classical strategy and CHSH game strategy.

Testing of a software product is the key activity before deploying it in the real-time environment. Therefore testing should be introduced into the product development process as early as possible in order to decrease the costs of repairing the damage in later phases. In this paper we use Coloured Petri Nets (CPN) for the system specification and also as a system to be tested instead of its implementation. This specification also serves as the basis for the test suite generation. Test cases are provided in the language of Testing and Test Control Notation version 3 (TTCN-3) due to its general application area and platform independence.

Comparing structure of graphical process models can reveal different variations of processes. Since most contemporary norms for process modeling lean on directed connectivity of objects in the model, their connections structure form sequences which can be translated into performing scenarios. While the sequences can be tested for completeness in performing process activities using simulation methods, the similarity or difference of static characteristics of sequences in different model variants is difficult to explore. The goal of the paper is to test the appliance of a method for comparison of graphical models by analyzing and comparing the static characteristics of process models. Therefore a metamodel of process models is developed and a comparison procedure conducted using a graphical model comparison algorithm.

Banks are important financial intermediaries of any national economy, and corporate governance has an important role in banking sector; especially due to processes of the globalization and the internationalization, and also because of the sensitivity of the activities between the interest groups. The objective of this paper is to examine the relationship between ownership structure, concentration, owners’ type and bank performance. The authors made a research of banks' ownership structure using publicly available data. Using statistical tools authors discovered relationships between bank ownership structure and bank performance indicators (average asset, total asset, average equity, profit (loss) before taxes, profit (loss) after taxes, ROAA, ROAE). Further they discuss the relationships between ownership structure and a number of consequences for the bank performance. The authors discovered significant correlation between bank ownership structure and performance indicators variables that are described in the paper.

The article aims to show that the classical document paradigm in information science has the greatest potential to grasp the issues related to the providing information to persons with visual disabilities and it aims to check whether the FRBR study is usable in this area. The article is divided into two parts. In the first part, the paradigmatic turns in information science are briefly presented and there is examined their impact on the issues connected with users with visual disabilities. The second part briefly describes the structure of the bibliographic universe and there is examined how it is possible to create a model of documents for users with visual impairment and of associated processes. The model of the bibliographic universe is applied to the situation of the really existing documents for visually impaired users. Methodologically, the article is based on the information system analysis. There is used an entity-relationship approach to a model of the bibliographic universe.

Considering a global importance of small and medium sized enterprises (SMEs) they are in the spotlight of ERP implementation retail stores. Many of the relevant studies indicate the importance and diversity of the ERP implementation process.  This paper presents results of the authors' research of the implementation success factors from the point of view of implementation participants. Based on the experience of a number of ERP implementations, authors compare the Croatian and international implementing practice of ERP solutions, taking into account the same critical success and the same ERP solution. Te emphasisis is put specifically on the three key participants in an implementation process: CEOs, project managers and successful-advanced users. Regardless of the relatively limited number of end users who took part in this study, it indicates a significant coincidence of Croatian and international practices in the part of perception of the critical success factors for ERP implementation, but also different views of key participants in the successful implementation.

Teachers are considered to be principal actors in the teaching process as well as one of its major constituents when quality and equity are concerned. Over the last decade a lot of papers have been published that deal with the quality of the teaching process and teachers. Most of them focus on students as the main subjects in evaluation of the teaching process and teachers. In this paper we analyze freshmen and senior students’ ability to differentiate between the evaluation of teacher and evaluation of teaching. In a lot of questionnaires used in research into this topic there is no difference in the approach to these two diverse aspects of the educational process quality. Since students are commonly the main target group of such questionnaires, in this paper we present the results of the study aimed at determining which elements, from the students’ perspective, are recognized and associated with teaching, and which ones with teachers.

The following article presents the possibilities of job optimization on a maritime container terminal, in order to increase the system productivity and optimize the terminal capacity. Automated guided vehicles (AGVs) are now becoming popular mode of container transport in seaport terminals. The moving of vehicles can be described as the set of discrete events and states. Some of these states can be undesirable such as conflicts and deadlocks. It is necessary to apply adequate control policy to avoid deadlocks and block the vehicles’ moving only in the case of dangerous situation.This paper addresses the use a Petri net as modeling and scheduling tool in this context. The aim of AGV scheduling is to dispatch a set of AGVs to improve the productivity of a system and reduce delay in a batch of pickup/drop-off jobs under certain constraints such as deadlines, priority, etc. The final goals are related to optimization of processing time and minimization of the number of AGVs involved while maintaining the system throughput.To find better solutions, the authors propose the integration MRF1 class of Petri net (MRF1PN) with a genetic algorithm. Also, the use of a matrix based formal method is proposed to analyze discrete event dynamic system (DEDS). The algorithm is described to deal with multi-project, multi-constrained scheduling problem with shared resources. The developed model was tested and validated by simulation of typical scenarios of the container terminal of Port Koper. Modularity and simplicity of the approach allow using the model to monitor and test the efficiency of the processes, and also to propose future alternative solutions to optimize the schedule of operations and the employment of AGV at the terminal.

The maximum clique in an undirected graph is the largest subset of  a set of graph's vertices where each pair of elements in the subset is connected. In this paper I would like to propose an algorithm for quantum computers that finds a maximum clique in an arbitrary undirected graph. An algorithm has O(|V|2|V|/2) worst case time complexity and O(2|V|/2) best case time complexity. Algorithm's space complexity for each case is O(|V|). An algorithm is based on a version of Grover's  quantum algorithm for finding element in an unsorted list in which there can be an unknown number of solutions.
