No full textThe Journal of Information and Organizational Sciences – JIOS – is an interdisciplinary scientific journal with a focus on the application of information sciences and advances in organizational sciences, as well as on theoretical contemplations in the fields that impact information sciences, computer sciences and organizational sciences. JIOS is published twice a year, and is managed by a team of professionals, all of whom are employed at the Faculty of Organization and Informatics, University of Zagreb.The Journal’s name and layout have already undergone several changes. As you can see, we have transformed our visual identity, and the format of the published papers has been changed as well. However, it is not only the visual identity of the Journal that we have been working on, as we have also aimed to enhance its visibility, accessibility and referencing. As a result, we are proud to say that the number of databases the Journal is cited in has grown from one to seven, and we are putting a lot of our e. orts into broadening this number in future.As you already know, the Journal’s web address has been changed to www.jios.foi.hr and it is currently being managed by the Open Journal System, in which the entire communication from submitting the paper to its reviewing and publishing is conducted on-line. In this issue of JIOS a selection of five original scientific papers and one review paper has been included covering the following topics: modern production management, fuzzy data, software and information systems development, online privacy and security, and fraud management. We hope you will find the papers interesting and challenging for your own research.Finally, we encourage you to submit your papers and also share with us your recommendations, comments or observations about papers already published. In that respect, we would very much appreciate your willingness to become a peer-reviewer for submitted papers, and thus contribute to the rising quality of JIOS
Method for Estimating the Complexity of Designing Business Information Systems
No full textThe most used method for determining the complexity of information systems is the function point method. This paper illustrates the new method, Data on Document (DOD) for estimating the complexity of designing business information systems. Similar methods are shown in brief. The objective is to explain the reasons for using the newly defined DOD method instead of the function point method. The new method is easier to use while the usage of function point method takes a lot of time and effort, and is more complex. The DOD method is compared to the function point method. A high degree of correlation was determined in observed information systems. The DOD method helps in early stages of the development of information systems, when it is not possible to apply the function point method
FINGERPRINTS PREPROCESSING USING WALSH FUNCTIONS
No full textoai:jios.foi.hr:article/4Minutiae classification and fingerprint classification in fingerprint evaluating process are very important. Fingerprint image contains about 150 minutiae’s. When we compare two fingerprint images, we compare latent and non latent fingerprint and we try to find 12 minutiae’s placed on the same position on latent and non latent fingerprint images. After fingerprint image pre-processing we can perform classification or we can try to find minutiae. In this paper we describe the process of minutiae classification for comparison purposes. For that purpose we use Walsh function and Walsh transforms. Paper describes minutiae classification which is relatively new in recognition systems and gives contribution for development of practical fingerprint recognition systems. Paper also gives contribution in the theoretical part due to the fact that Walsh functions were not implemented in fingerprint pre-processing systems so far. The new symbolic database model for fingerprint storage gives multifunctional foundations for future research
PREDICTING THE INTENTION TO USE INTERNET – A COMPARATIVE STUDY
No full textThis article focuses on an application of the Triandis Model in researching Internet usage and the intention to use Internet. Unlike other TAM-based studies undertaken to date, the Triandis Model offers a sociological account of interaction between the various factors, particularly attitude, intention, and behavior. The technique of Structural Equation Modeling was used to assess the impact those factors have on intention to use the Internet in accordance with the relationships posited by the Triandis Model. The survey was administered to Croatian undergraduate students at and employed individuals. The survey results are compared to the results of a similar survey that was carried out by two universities in Hong Kong
Evaluation Framework for Quality Management Software
No full textIdentifying and specifying user requirements is an integral part of information systems design and is critical for the project success. More than 50% of the reasons for the project failure presented in the CHAOS report [36] and study of a US Air Force project by Sheldon et al. [33] are related to requirements. The goal of this paper is to assess the relevant user and software requirements which are the basis for an electronic quality management system selection in medical device companies. This paper describes the structured evaluation and selection process of different quality management software tools that shall support business processes. The purpose of this paper is to help the small to medium size medical device companies to choose the right quality management software which meets the company's business needs
Shot Boundary Detection in Soccer Video using Twin-comparison Algorithm and Dominant Color Region
No full textThe first step in generic video processing is temporal segmentation, i.e. shot boundary detection. Camera shot transitions can be either abrupt (e.g. cuts) or gradual (e.g. fades, dissolves, wipes). Sports video is one of the most challenging domains for robust shot boundary detection. We proposed a shot boundary detection algorithm for soccer video based on the twin-comparison method and the absolute difference between frames in their ratios of dominant colored pixels to total number of pixels. With this approach the detection of gradual transitions is improved by decreasing the number of false positives caused by some camera operations. We also compared performances of our algorithm and the standard twin-comparison method
Holistic approach to fraud management in health insurance
No full textFraud present an immense problem for health insurance companies and the only way to fight fraud is by using specialized fraud management systems. The current research community focussed great efforts on different fraud detection techniques while neglecting other also important activities of fraud management. We propose a holistic approach that focuses on all 6 activities of fraud management, namely, (1) deterrence, (2) prevention, (3) detection, (4) investigation, (5) sanction and redress, and (6) monitoring. The main contribution of the paper are 15 key characteristics of a fraud management system, which enable construction of a fraud management system that provides effective and efficient support to all fraud management activities. We base our research on literature review, interviews with experts from different fields, and a case study. The case study provides additional confirmation to expert opinions, as it puts our holistic framework into practice
Conceptual Modelling of Complex Production Systems
No full textComplex system dynamics, structure and behaviour performances call for a wide range of methods, algorithms and tools to reach a model capable of finding optimal performing parameters. In the modelling process, it is up to the analyst to select the appropriate combination of methods, algorithms and tools to express significant system performances. Such a methodology for designing complex systems should be based upon conceptual modelling to perform a sensitive analysis of different system levels and views, allowing system representations for developing computer models.Complex systems, such as business systems with a continuous-discrete production process, require a well organised supply chain highly reactive to production assortment changes. Aligning two different production components distinctive in their behaviour is especially delicate at the production parameters transition point. Such system performances require distinctive designing methods that can follow the double nature of the production process behaviour in accordance with their entities dynamics caused by assortment changes. Consequently, such systems need different conceptual presentations for their purpose to be realized from different views and aspects
Theory of Microcrediting in Transitional Economies
No full textIn the early 1970s, Bangladeshi banker and economist Dr. Muhammad Yunus designed microcrediting – a socially sensitive and rightful system of fighting poverty and high unemployment rates. His Grameen Bank for the poorest of the poor in Bangladesh has so far lifted more than 3.2 million of individuals and their families out of poverty. After initial successes at home, microcredit was put into service for reducing unemployment and alleviating poverty in numerous countries throughout the world.
This paper explores specific problems that a typical transitional country (like Croatia), is likely to face, with unemployment – the source of a vast number of related problems in a transitional society – as the focal point. The authors have attempted to incorporate particularities of a transitional economy into the original microcrediting principles. As a solution to problems afflicting the domestic economy, the authors define a global microcrediting system framework on the macroeconomic level, assuming at the same time that microcrediting of socially vulnerable groups can resolve many problems of modern transitional societies. Arising from the authors' primary intention – to consider in depth the functionality of microcrediting in general transition conditions – a transitional microcrediting system has been defined in general terms, and a corresponding financial and mathematical model developed
Factors and Predictors of Online Security and Privacy Behavior
No full textAssumptions and habits regarding computer and Internet use are among the major factors which influence online privacy and security of Internet users. In our study a survey was performed on 312 subjects (college students who are Internet users with IT skills) that investigated how assumptions and habits of Internet users are related to their online security and privacy. The following four factors of online security and privacy related behaviors were revealed in factor analysis: F1 – conscientiousness in the maintenance of the operating system, upgrading of the Internet browser and use of antivirus and antispyware programs; F2 –engagement in risky and careless online activities with lack of concern for personal online privacy; F3 – disbelief that privacy violations and security threats represent possible problems; F4 – lack of fear regarding potential privacy and security threats with no need for change in personal online behavior. Statistically significant correlations were found between some of the discovered factors on the one side, and criteria variables occurrence of malicious code (C1) and data loss on the home computer (C2) on the other. In addition, a regression analysis was performed which revealed that the potentially risky online behaviors of Internet users were associated with the two criteria variables. To properly interpret the results of correlation and regression analyses a conceptual model was developed of the potential causal relationships between the behavior of Internet users and their experiences with online security threats. An additional study was also performed which partly confirmed the conceptual model, as well as the factors of online security and privacy related behaviors
