CALL FOR PAPERS, SPECIAL ISSUE, INTERNET OF THINGS

Nowadays, Internet has evolved into a platform that reshapes modern life and removes borders between real, social and cyber worlds. Internet of Things (IoT) is an emerging paradigm and a cutting edge technology that harnesses a network of embedded, interconnected objects (sensors, actuators, tags or mobile devices) in order to collect various types of information at anytime and anywhere. These devices can be used for building different complex smart environments, such as smart homes, smart classrooms, smart offices, smart factories, smart cities, smart power grids or smart e-government. Further, the networks of devices are based on advanced Internet standards. IoT implies seamless integration of numerous types of devices into existing Internet infrastructure. Smart environments can be customized according to users’ needs and preferences which are suitable for automating these environments

Enhancing the customer relationship management in public libraries: findings from three developing countries

Purpose – The purpose of this paper is to investigate the possibilities of implementing the customer relationship management (CRM) concept and smart technologies in public libraries in developing countries. The goal was to explore the level of librarians’ awareness about CRM concept and their willingness to accept the CRM concept in libraries. Also, patrons’ satisfaction with the quality of services and relationships in public libraries is explored. Design/methodology/approach – The authors obtained data for this research through two online surveys. The first survey measures librarians’ level of awareness about CRM concept and their perception about CRM and smart technologies concept in public libraries in three developing countries: Serbia, Montenegro and Bosnia and Herzegovina. The second survey measures patrons’ satisfaction with services and relationship in public libraries in these three countries. Findings – The research results revealed that most surveyed librarians are familiar with the CRM concept. However, libraries in these three developing countries barely use CRM or smart technologies to improve the relationship with stakeholders. Also, most patrons are satisfied with relationships and services. The analysis of data indicates no significant difference in the satisfaction level among patrons between these three developing countries. Research limitations/implications – Not all libraries participated in this research. Therefore, the sample is not distributed evenly across different types of libraries or user groups. Future research should include different types of libraries. Practical implications – The results can be used by public libraries in developing countries to improve the relationship with stakeholders harnessing CRM concept and smart technologies. Social implications – The use of CRM in combination with the smart technologies can help leverage the quality of the relationship between public libraries and stakeholders which in turn would secure their support and loyalty in the future. Originality/value – The integration of CRM concept as a component of library business automation process is an idea that has not been discussed widely in the library community and could initiate a positive trend in public libraries in developing countrie

Creating Adaptive Environment for e-Learning Courses

In this paper we provide an approach to creating adaptive environment for e-learning courses. In the context of e-education, successful adaptation has to be performed upon learners’ characteristics. Currently, modeling and discovering users’ needs, goals, knowledge preferences and motivations is one of the most challenging tasks in e-learning systems that deal with large volumes of information. Primary goal of the research is to perform personalizing of distance education system, according to students’ learning styles. Main steps and requirements in applying business intelligence techniques in process of personalization are identified. In addition, we propose generic model and architecture of an adaptive e-learning system by describing the structure of an adaptive course and exemplify correlations among e-learning course content and different learning styles. Moreover, research that dealt with application of data mining technique in a real e-learning system was carried out. We performed adaptation of our e-learning courses using the results from the research

GUEST EDITORIAL

Nowadays, Internet has evolved into a platform that reshapes modern life and removes borders between real, social and cyber worlds. Internet of Things (IoT) is an emerging paradigm and a cutting edge technology that harnesses a network of embedded, interconnected objects (sensors, actuators, tags or mobile devices) in order to collect various types of information at anytime and anywhere. These devices can be used for building different complex smart environments [1], such as smart homes [2][3], smart classrooms [4], smart offices [5], smart factories [6], smart cities [7], intelligent transportation systems [8], smart power grids [9] or smart e-government. Further, the networks of devices are based on advanced Internet standards. IoT implies seamless integration of numerous types of devices into existing Internet infrastructure. Smart environments can be customized according to users’ needs and preferences which are suitable for automating these environments. Internet of things solutions often encompass integration with cloud-based systems and services [7]: Infrastructure as a service (IaaS), Platform as a service (PaaS) and Software as a service (SaaS)

DEVELOPMENT OF AN IOT SYSTEM FOR STUDENTS' STRESS MANAGEMENT

This paper shows the development of an IoT system for students' stress management. The IoT system is developed in an open architecture and is an integral part of the educational ecosystem. The system is composed of two elements: the one that enables measurement of vital parameters for identifying stress in students, and the other for stress control. The system for stress control consists of a mobile health application featuring relaxation content. Such system should minimize the excitement and have an impact on reducing future stress. The IoT system for stress management was evaluated in a real environment, during students’ thesis defense on Faculty of Organizational Sciences, University of Belgrade. The results show that time spent using mobile health application with relaxing content can reduce students’ physiological arousal and excitement during thesis defense
