Klasinc (Vertex projekt, Zagreb, Croatia) Distributed Governance of Life Care Agreements via Public Databases  The issue of life care agreements or permanent life support contracts for elderly citizens is highly controversial in many countries, including Croatia. The problem of the increasing number of elderly citizens without sufficient retirement savings and no relatives or children that are able to care for them may be resolved by tapping into the equity of the property they live in, such as a house or an appartment. However, in some countries, such as the US, the model used is essentially based on insurance policies, financial institutions and - which is not always immedialtely apparent - loans, which means that it includes interest rates, and if the person happens to live longer than the loan provided by the bank, it may foreclose and terminate the contract while the occupant is still alive in order to preserve its interests. In Croatia this legal situation is regulated by so called permanent life support contracts 'until death' or 'during lifetime', by which the provider of support may become the legal owner upon signature of the contract or after the death of the other parties to the contract (such as husband and wife). Monitoring of such contracts is very difficult due to incapacity and old age of one party to the contract and lack of close persons and relatives involved; thus, different unethical situations may arise, such as people not receiving the support and nevertheless being evicted or moved away from their homes. The Ombudsman of the Republic of Croatia proposed, therefore, in 2015, that an electronic database of such contracts should be maintained in order to increase transparency and monitor certain situations, such as when a single support provider takes care of several - 10 or even more - receivers of support, going after the property of the other parties to such contracts. Such database is, indeed, maintained by the City of Zagreb, but not many other local government units. As the issue has its economic, legal, as well as human rights side, it is analysed from all those perspectives in order to arrive to the optimum solution to the problem, that can satisfy both the support providers and receivers, and in our opinion such a solution makes use of ICTs and distributed public governance, allowing better control of the execution of all permanent life support contracts by interested parties, as well as better adjustment and resolution of controversial situations that may arise during the execution of the contracts (such as caretakers not providing services or insufficient amount of compensation due to low value of the property or the longevity of the support receiver(s)). 2.

Vojković (Fakultet prometnih znanosti, Zagreb, Croatia) Using Public Private Partnership Models in Smart Cities– Proposal for Croatia  How smart is a ''smart city''? According to Asian examples of newly growing smart cities, usage of technology can improve life standard and reduce cost of living, improve operational efficiency, environmental sustainability, eco-friendly infrastructure, smart technology (IoT), smart living and direct citizen participation in decision making process. Learning, adaptation and innovation could be the future for Croatian cities by using all mentioned which will improve social, regulatory and safety indicators for designing a better living environment for Croatian citizens. While using Public Private Partnership (PPP) models, crowdfunding, crowdsourcing and democratic ecologies which provide better and more efficient public services by taking advantage of private sector's ''know-how'', cities will create long-term investment opportunities and sustain real time optimization strategies by providing safe and reliable place to invest. The intention of this paper is to show and demonstrate how the (local) government's role in PPP projects is to evaluate and approve detailed execution plans of the concessionaire while the private partner’s role is to design, build, finance, and operate the facilities. In futuro, digital technologies offer numerous possibilities for citizen participation in decision making at local and regional government level. 3. M. Sretenović (MI&DA d.o.o., Karlovac, Croatia), B. Kovačić ( Department of Informatics, University of Rijeka, Rijeka, Croatia), A. Skendžić ( Polytechnic Nikola Tesla, Gospić, Croatia) The Platform for the Content Exchange between Internet Music Streaming Services and Discographers  Internet streaming is the type of technology that allows simultaneous reception of multimedia content and its simultaneous playback through a computer network. Global development of the Internet leads to growing demand for multimedia content. Discographers deal in distribution and sale of rights to play audio recordings (tracks), adapting their business to new technologies and modern ways of selling their products and services in order to survive in the market impacted by a large drop in demand and sales of CDs and DVDs. In the process of rationalization and automation of business processes, new standards in the electronic exchange of data are set between discographers and Internet streaming services with the goal to increase efficiency and economy. This paper describes a platform for the exchange of data and content, presents the concept and the basic methods used in the development of an automated system for the exchange of data and content between discographers and Internet streaming services and offers guidelines for future development. 4. N. Gumzej ( Faculty of Law, Zagreb, Croatia) Law and Technology in Modern Data Processing Systems: Risk-Based Approach to Data Protection and Implementation Challenges  Recently adopted General Data Protection Regulation (GDPR) will apply EU-wide already as of mid-2018 while many of its segments require clarification. Critically important are new requirements that need to be implemented into technological and organizational processes and assessed in order to ensure adequate security of processing and risk management. Fulfilling the duty to ensure levels of security in data processing systems that are appropriate to underlying risks requires a proper methodological approach toward identification of risks for individuals’ rights and freedoms and their levels of likelihood and severity. The same applies for data protection impact assessment procedures that will become mandatory whenever types of personal data processing, especially using new technologies, and taking into account the nature, scope, context and purposes of processing, are likely to result in a high risk to individuals’ rights and freedoms. In light of aforementioned concerns the author will critically assess GDPR solutions toward risk management and impact assessments, while focusing on questions such as risk definition, impact of technology-enabled surveillance on a wider group or rights and freedoms, role of public participation, and challenges towards a harmonized methodology. The local perspective, i.e., assessment of Croatian legislation and practice will contribute to the deeper understanding of the challenges in incorporating an overall risk-based mentality in data protection EU-wide, towards the timely harmonized legal protection under the GDPR. 5. S. Vojvodić (Ericsson Nikola Tesla d.d., Zagreb, Croatia), S. Čegar (Ekonomski fakultet Rijeka, Rijeka, Croatia), D. Medved (Ericsson Nikola Tesla d.d., Zagreb, Croatia) Social and Economic Effects of Investments in Primorsko-goranska County Broadband Network  The paper deals with the methodology applied to data collection, as well as social, economic, and financial analysis of broadband investments’ effects related to the planning of broadband infrastructure development of the Primorsko-goranska County (PGC), with the City of Rijeka in focus. The analysis of the collected data and derived indicators has yielded results which can be significant for local and regional policy makers. It has been shown that investments in broadband infrastructure have a relatively high social return on investment and produce multiple socioeconomic benefits that can not only accelerate the development of cities and municipalities in PGC, but also contribute to inhibiting or turning negative demographic trends around. 6. Đ. Bunja, G. Pavelin (University of Zadar, Zadar, Croatia), F. Mlinac (Sutivan Public Library, Sutivan, Croatia) Mobile Applications in Communication of Local Government with Citizens in Croatia  Based on perceived practices in developed countries of the world, this paper deals with the theory of the mobile applications implementation in local self-government. The development of corresponding mobile applications reduces ICT expenses and the expenses of contacts with clients. The share of resources among the bodies of local self- government is facilitated and services offered to local community are modified. By providing self-service applications to their users, local self-government responds to their needs and demands while creating a platform on which other public services, profit and non-profit organisations can be upgraded with the goal of providing their services to everyone who needs them. This paper provides an explanation of most frequently used types of applications and it examines the use of mobile applications in bigger Croatian local governments. 7. S. Hyrynsalmi, P. Linna (Tampere University of Technology, Pori, Finland) The Role of Applications and Their Vendors in Evolution of Software Ecosystems   The most recent trends in the electronic commerce research have suggested that forming an ecosystem around a platform would create a winning solution. The ecosystem, consisting of vendors and external actors, would create competitive advantage for the platform owner. Furthermore, the sheer number of the actors has been used as the measure of the ecosystem’s well-being against competing ecosystems. Whereas a number of studies has been devoted to analyse the well-being indicators or structures of software ecosystems and the importance of complementors and complements are acknowledged, there is lack of studies addressing how the complementors affect into the evolution of ecosystems. This conceptual analysis aims to open discussion on this topic by using the mobile application ecosystems—such as Google Play or Apple’s iOS—as the case subject. While the results suggest some implications for the platform owners and complementors, more work is needed. 8. P. Linna, T. Mäkinen, K. Yrjönkoski (Tampere University of Technology, Pori, Finland) Open Data Based Value Networks: Finnish Examples of Public Events and Agriculture  In recent years, several countries have placed strong emphasis on openness, especially open data, which can be shared and further processed into various applications. Based on studies, the majority of open data providers are government organizations. This study presents two cases in which the data providers are companies. The cases are analyzed using a framework for open data based business models derived from the literature and several case studies. The analysis focuses on the beginning of the data value chain. As a result, the study highlights the role of data producers in the ecosystem, which has not been the focus in current frameworks. 9. F. Gabela, A. Gabela, J. Gabela (BH Telecom, Sarajevo, Bosnia and Herzegovina) Elektronički dokazi s osvrtom na zakonska rješenja elektroničkih dokaza u Bosni i Hercegovini  Razlike između pravnih sustava država članica Ujedinjenih naroda nametnule su problem usklađivanja pravne regulative kao prioritet međunarodne zajednice. Problem prepoznavanja određenog ponašanja kao ilegalnog u jednoj državi i tretiranje istog tipa ponašanja kao legalnog u nekoj drugoj, pruža prostor za izbjegavanje krivične odgovornosti. Drugi problem koji se javlja je problem nadležnosti. Kod ove vrste problem nastaje korištenjem tehnologije koja omogućava rad s udaljenih lokacija, odnosno upotrebu resursa u jednoj državi za obavljanje aktivnosti u drugoj, dok se operativni rad obavlja u nekoj trećoj državi. Upravo iz razloga koordinacije i efikasne borbe protiv kriminala, neophodno je što više približiti zakonsku regulativu, odnosno uskladiti procese prikupljanja i analiziranja elektroničkih dokaza. Međunarodna je organizacija za računalnu registraciju, propisala opće principe i procedure koje se odnose na elektroničke dokaze, za usaglašavanje metoda i praktičnih rješenja među državama, koje garantiraju međunarodnu razmjenu elektroničkih dokaza. Bosna i Hercegovina je preuzela obaveze za krivična djela iz područja računalnog kriminala, a samim time i nova zakonska rješenja u području elektroničkih dokaza. 10. S. Aksentijević (Aksentijević Forensics and Consulting, Ltd., Viškovo, Croatia), E. Tijan, A. Jugović (Sveučilište u Rijeci, Pomorski fakultet, Rijeka, Croatia) Financial Impact of Forensic Proceedings in ICT  Application of scientific forensic methods in ICT has become a mainstream methodology not only in criminal and civil proceedings, but also in preventive maintenance of various aspects of ICT systems used by corporations, governmental and other institutions. However, despite efforts of solution providers to create forensic hardware, software and procedures that are purported to be easy to use even by those that are not forensic experts, in most cases forensic proceedings are connected with high utilization of financial and temporal resources. Accelerated changes in information technology and architecture also require additional regulation that will pre-emptively ensure adequate amount and form of forensic trail left for possible future investigations. This paper is an attempt to describe current state of affairs of forensic proceedings, the latest trends and to provide comment on their financial impact and consequential real-world feasibility. 11.

This paper discusses the quantitative indicators of the quality of the computer system supported by RFID technology applied in monitoring facilities (pallets, packages and people) marked with RFID tag. Results of analysis of quantitative indicators of quality computer system supported by RFID technology are presented in tables. 12. I. Pavić, N. Holjevac, M. Zidar, I. Kuzle (Faculty of Electrical Engineering and Computing, Zagreb, Croatia), A. Nešković (School of electrical Engineering, Belgrade, Serbia) Transportation and Power System Interdependency for Urban Fast Charging and Battery Swapping Stations in Croatia  An increasing penetration of electric vehicles in recent years has been driven by government and municipal subsidies, tax exemptions, parking access priority, as well as by the citizens’ increased environmental awareness. Electric vehicles indisputably bring benefits to their drivers and society in general, indirectly through global warming and greenhouse gas emissions mitigation and directly through financial savings and cleaner microclimate. However, integration of electric vehicle charging spots at home or work, especially fast charging stations and battery swapping stations, without prior analysis can have a negative effect on power system. In order to predict and eliminate power grid issues before they occur, a detailed analyses should be made through a common understanding of both transportation and recharging needs of electric vehicles’ users and of the power grid constraints. Power and transportation system interdependency becomes of high value for correct placement and sizing of charging stations and for overall increase of social welfare. This paper analyzes electric vehicles charging needs at the basic level, through both the power system and the transportation system. An urban transmission and power grid in the vicinity of the Croatian capital Zagreb is used as a study case. Driving and electricity consumption curves are compared, locations for charging infrastructure are selected (fast charging spots and battery swapping station) and power grid’s available capacity is defined. 13. Ž. Kovačević, M. Mauher, M. Slamić (Tehničko veleučilište u Zagrebu, Zagreb, Croatia) Croatian Qualification Framework – Data Model and Software Implementation in Higher Education  Project „Politehnika 2025“ was started by Tehničko veleučilište u Zagrebu in cooperation with APIS IT, IN2 GRUPA and SPAN companies. The goal was to analyze future market needs until year 2025 and to upgrade existing and to develop new study programs that would modernize polytechnic studies. Project success depended on collecting and analyzing a large amount of data, and to do that it was required to develop appropriate information system. That included to create a conceptual database model and later to write applications that would allow all project participants to work with data. The goal of this paper is to describe database model and its parts, all applications used in the process of gathering and reviewing data and their features. Information system was one of the key elements of the project since without it the project would not be able to complete in desired period and its results may be prone to errors. 14. B. Knežević (Faculty of Economics Zagreb, Zagreb, Croatia), Z. Pavlić Šipek (Faculty of Economics Zagreb (postgraduate student), Zagreb, Croatia), B. Jaković (Faculty of Economics Zagreb, Zagreb, Croatia) Internet as a Purchasing Information Source in Children’s Products Retailing in Croatia  The intensive development of technology, the global availability of the Internet, the overall network coverage and increasing of computer literacy within the population, are growth factors that contribute to popularization and importance of electronic commerce. Moreover, electronic commerce is described as an effective way of communication with consumers in terms of money and time expenditures, and, therefore, in recent decades its role is growing rapidly both in general and specialized retailing. There are numerous research studies that describe and analyze the growth and general potentials of e-commerce. However, the level of development and potential in the field of special commodity groups are not yet sufficiently explained nor practically explored. The aim of this paper is to fill this gap through explanation of Internet as a purchasing source in a particular field of children’s products retailing. 15. Z. Prohaska, I. Uroda (University of Rijeka, Faculty of Economics, Rijeka, Croatia), A. Radman Peša (University of Zadar, Department of Economics, Zadar, Croatia) Valuation of Common Stocks Using the Dividend Valuation Approach and Excel  The valuation of common stocks using the dividend valuation method is useful for stocks in so called no-growth or constant-growth situations. In the case of constant-growth the stock price should be equal to the discounted present value of all future dividends, but in the case of non-constant growth the case becomes more complicated. In both cases the use of Excel is a straightforward method for solving such calculations efficiently. 16. M. Boban (Pravni fakultet Split, Split, Croatia), T. Šušak (Ekonomski fakultet Split; Sveučilišni odjel za stručne studije, Split, Croatia) The Interconnection between Investment in Software and Financial Performance – The Case of Republic of Croatia  Nowadays, information technology is condition sine qua non of every successful business. The implementation of daily tasks is aggravated or impossible without use of IT. In this sense, many questions emerge – can companies use information technology as their competitive advantage? Is IT potentially the generator of increasing the financial result of a company? Specifically, the object of consideration in this paper is software, which is indispensable in terms of giving functionality to company’s assets – hardware. In terms of finance and accounting, software is considered as intangible fixed asset which will be used for period longer than one year. The era of companies mainly focused on tangible assets has passed, which implies that the average intangible assets to total assets ratio is rapidly increasing nowadays. At the same time, there is also a growth of industries which are greatly dependent on this category of assets. Bearing in mind that software is developed by the programmers, its quality can vary significantly. When developing specialized business software, it is not only important to have skilled programmers, but also to include experts who have the knowledge of certain business processes. If we take into consideration abovementioned facts, it is evident that the quality of software is inherent to successfully established business process that could potentially lead to optimal use of resources, i.e. save time and money. Statistically, the main aim of this paper is to examine the relationship between investment in software and financial performance of a company. In other words, determine if investment in information technology is significant stimulus in terms of improving financial performance of a company. The research sample was formed using companies listed on Zagreb Stock Exchange (ZSE). The data used in the statistical analysis was gathered from the financial statements publicly available at ZSE’s official website.
