No full textDear 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.

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 VrčekEdito
An Artificial Neural Network Modeling for Force Control System of a Robotic Pruning Machine
No full textNowadays, 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
Using Coevolution Genetic Algorithm with Pareto Principles to Solve Project Scheduling Problem under Duration and Cost Constraints
No full textThis article considers the multicriteria optimization approach using the modified genetic algorithm to solve the project-scheduling problem under duration and cost constraints. The work contains the list of choices for solving this problem. The multicriteria optimization approach is justified here. The study describes the Pareto principles, which are used in the modified genetic algorithm. We identify the mathematical model of the project-scheduling problem. We introduced the modified genetic algorithm, the ranking strategies, the elitism approaches. The article includes the example
Information Technology and Accounting Information Systems’ Quality in Croatian Middle and Large Companies
No full textAn accounting information system is of a great importance for preparing quality accounting information for a wide range of users. The study elaborates the impact of information technology on accounting process and as a consequence on accounting information systems quality. This paper analyzes the basic characteristics of accounting information systems quality, discussing the model of AIS’s quality measurement. The perception of the quality of accounting information systems by accountants in medium and large companies in Croatia is also presented. The paper presents the historical overview of AIS’s quality based on three empirical studies conducted in 2001, 2008 and 2012
The Application of Multimedia Aimed at Improving the Acquisition of Typical Topics in Natural and Social Science Programs in High Schools
No full textThe 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.

Dynamic Aspects of the Strategic Planning of Information Systems
No full textThe 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
Interpretation of Fuzzy Attribute Subsets in Generalized One-Sided Concept Lattices
No full textIn 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
Impact of Aspect-Oriented Programming on the Quality of Novices’ Programs: A Comparative Study
No full textAspect-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
Creating TTCN-3 Test Suite from CPN Specification
No full textTesting 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
