CRM is often seen as a key element in delivering customer-centric services. Today CRM solutions are often implemented as a cloud computing service. Cloud computing refers to providing and using computational resources via the Internet. It enables the access to technology in the form of service on demand. Services and data coexist in shared and dynamically scaled set of resources. E-government is the organic combination of information technology and government management function. With the development of information technology, government has been upgrading from management-oriented mode to service-oriented one. Therefore, government CRM is a business strategy to provide comprehensive service from all public organizations. This paper presents a model of CRM in e-government system. Model includes process specification, metrics for evaluation of the system performance and recommendations for implementation. 1 Marko Vulić was born in 1985, in Belgrade, Serbia.

As teaching associate he is involved in teaching courses covering the area of E-business, Internet marketing and E-education.

The specific goal is to design a smart environment for enhancing the teaching and learning processes at universities. The environment should integrate adequate concepts of smart buildings and smart classrooms with e-learning systems, in order to provide students with advanced e-learning services and services that improve the overall quality of students' experience. In addition, the model is based on the concept of crowdsourcing, where students actively participate in gathering the information, designing and implementing the e-services. Finally, the paper describes a prototype of the designed smart environment implemented at the Department for e-Business, at University of Belgrade.

The application is based on web services and it is integrated with an existing e-learning system. Main users of the applications are teachers and students and the application consists of two main parts which are web application and mobile application. The application is successfully implemented at the e-Business Laboratory of the Faculty of Organizational Sciences in Belgrade.

Social media can be described as Web 2.0 technologies and practices that are used for sharing content, opinions and experiences. The application of social networks, wikis and blogs enables improvement relations between the participants of the educational process. In this paper we present a model for application of social media in e-learning, developed in scope of Laboratory for e-business, Faculty of organizational sciences, University of Belgrade. The practical part of the paper describes the use of wikis, blogs and social networks, as a complement to the existing elearning process, in a higher education institution. Integration of an edutainment Facebook application with Moodle learning management system is shown. The main goal of this paper is the improvement of quality of e-learning process through application of social media in higher education.

In this paper, a workshop for organizing a lab in academic environment for the subject Internet of Things is described. The architecture of the platform, scenario and a description of components used for creating the environment for learning Internet of things are also given in the paper. Students use their knowledge related to creating Android mobile applications and SMS services, as well as given sensors, microcontrollers and microcomputers to create an application for smart home automation.

The goal of the designed model is to provide university students with knowledge about IoT concepts, possibilities, and business models, and allow them to develop basic system prototypes using general-purpose microdevices and a cloud and service infrastructure. The model was based on a cloud infrastructure deployed at the E-Business Department at the Belgrade University, and some implementation details are given. The model was tested and evaluated

The primary goal is to improve the performance of the existing e-learning system where group adaptation is applied. The proposed method includes an integration of information, processes, applications and human resources in the e-learning system. Integration is based on a web application we developed for managing the learning environment. The application enables an integration of the Moodle, the OpenLDAP directory for managing user accounts, and the OpenNebula toolkit for managing a cloud computing infrastructure. The major advantage of the suggested approach is that the existing system for adaptive e-learning does not need any changes, while it becomes more available and suitable for ubiquitous learning. We evaluated the implemented environment in an undergraduate course at the E-Business Lab, University of Belgrade.

One of the main challenges in developing e-government services is a huge number of users (citizens and enterprises). Thus, a highly scalable infrastructure is required for developing these services. Cloud Computing is one approach for creating a scalable infrastructure. Cloud Computing is a part of computer science and it enables providing Internet services to external customers via very scalable computing capacities. It is abstracted, high-scalable and controlled computer infrastructure which hosts applications for end-users. Data and services are located in shared, dynamic and scalable set of resources based on technologies of virtualization and scalable application environments. For enhancing egovernment services, there is a need for deploying virtual servers and storing data in Cloud Computing environment. Dat...

The affordance of mobile technology can be exploited to make e-government more pervasive and equitable. The advances of mobile technology have empowered citizens with means to access information and use e-government services from anyplace and anytime. Mgovernment stands for the use of mobile technologies within the government administration to deliver public services to citizens and companies. Main subject of this paper is analysis of potentials and benefits that mobile technologies can bring to e-government services. We analyze the need and possibilities for implementing mgovernment services. We provide a model for implementing mobile government services through cloud computing infrastructure. We present a generic framework to encourage e-government practitioners to be easily involved in the design and development process to generate more m-government services, document 1 Konstantin Simić was born in 1985, in Belgrade, Serbia.

However, this can reduce system security and lead to insufficient usage of the services by end-users. This chapter investigates various approaches for identity management, particulary in a cloud computing environment. Several complex issues are discussed, such as cross-domain authentication, provisioning, multi-tenancy, delegation, and security. The main goal of the research is to provide a highly effective, scalable identity management for end-users in an educational private cloud. A federated identity concept was introduced as a solution that enables organizations to implement secure identity management and to share information on the identities of users in the cloud environment. As a proof of concept, the identity management system was implemented in the e-learning system of Faculty of Organizational Sciences, University of Belgrade.
