There is no doubt that modern society depends heavily on information technology in nearly every facet of human activity. Organizations of all kinds are increasingly exposed to various kinds of risks, including information technology risks. There are many security standards and frameworks available to help organizations manage these risks. The question which one is best and can address the information security risks adequately warrants further investigation and research. The purpose of this research work is to highlight the challenges facing enterprises in their efforts to properly manage information security risks when adopting international standards and frameworks. To assist in selecting the best framework to use in risk management, the article presents an overview of the most popular and widely used standards. It then identifies some selection criteria and suggests an approach to proper implementation. A case study is used to prove the usefulness of the new model for selecting an appropriate security model to manage information security risks.

The iPad as a learning tool has made its way into many elementary school classrooms worldwide. It holds a promise to be a game changer in elementary school education supporting more constructivist learning practices. This paper offers an insight into what happened when, in two elementary school classrooms, the students were enabled to generate both content and context for their own learning. One of the cases describes how the 5th grade children influenced their teacher and obtained permission to use one of the iPad’s creativity apps over a two-week period in order to learn about writing. The second case is about 6th graders involvement in a participatory design process aiming to design an application for the iPad. The application was to support learning about media production by enabling students to publish a weekly newsletter describing their school week in words, pictures and video. The children participating in the studies evaluated the projects as truly successful. The children’s criteria of success were how cool, fun and enjoyable it was to use the iPad. The teachers did not find the projects to be successful. The main criterion they used was the learning outcome. Both teachers found the learning outcome to be inferior to what they usually obtain using traditional teaching methods. Both teachers preferred to use the iPad as a plug-on to traditional ways of teaching. Although our study is small, the results point towards important issues, such as the evaluation process and the decision making process, that may have large influence on the use of technology in the classroom.

This paper is centered on the implementation problems of learning activities for better education in a global and information society. Modern education must respect dynamic changes in society based on preferences of business and need for competitive advantages; therefore, education seeks optimal ways to obtain the necessary knowledge and skills. Communication has an important place in education. The presented analysis is dedicated to Forum activity, with links to other learning activities like Database, Survey, or Wiki from the Moodle platform. The Forum activity is difficult for creation. Teacher must use on-line help or a specialist on the Moodle for optimal Forum creation via eighteen items. Other analyzed activities need smaller volume of work, but prompt implementation requires simplification using ideas of computational intelligence, and e- learning for knowledge society.

This paper describes modern software based flexible measuring systems for analysis of digitally modulated systems. The latest methods for evaluation of modulation parameters using new generation test systems based on PXI modular platform and graphical programming in LabVIEW are demonstrated. Authors concentrate on the most widely used modulation technique used in radio communication systems - QPSK. On the real measurement of the QPSK modulation parameters, authors attempt to make the readers acquainted with not very widespread synthetic measuring instruments in the application area of wireless transfer systems. The basic idea of functionality of these instruments comes from the definition of the software radio. Experiments themselves demonstrate the fundamental differences in the conception of traditional and synthetic instrumentation. The focus is mainly on the different understanding of the key component in the form of software and hardware for both investigated platforms.

In this paper, we present first experiences with the use of a lightweight, media-supporting quiz application for mobile devices. The idea is to use the students’ own smartphones and laptops as voting devices and provide a quiz administration module which is integrated into the existing university’s e-learning platform. For establishing the link between the devices and the platform we use dynamically generated Quick Response (QR) codes. The quiz is implemented as a web application, also providing the use of media content such as pictures and videos. We evaluate our approach with respect to usability, limitations of the mobile browser technology, the QR code, and the impact on the university’s network infrastructure. Furthermore, we discuss the usefulness and usability of the quiz tool on the base of students’ evaluations and our experiences while working with the lecturers.
