During times when remote or hybrid teaching is inevitable, many instructors record their class sessions for greater student accessibility. Recordings allow students to follow classes at their own pace, when it suits them, to watch class sessions they missed due to unexpected circumstances, review complex concepts, and fill in gaps in their lecture notes when studying for exams. At the same time, class recordings can result in waning attendance or student engagement. The objective of the empirical study presented in this paper is to determine which factors contribute to the acceptance of class recordings and how often they have been effectively consumed by information and computer science students of one higher education institution in Croatia. Reported findings uncovered that students are willing to learn course topics from class recordings because they have met students' expectations and can therefore serve as an equal replacement for in-class attendance.

The complexity of the process control systems within the industrial environment increases rapidly over the years. This may not be the critical issue for the design of the control system itself, but human limitations place operators in a difficult position facing an increasing level of complexity of the Human- Machine Interface (HMI) with growing amounts of data and control parameters. This paper proposes a lightweight web-based software solution in the form of the addition to the existing control system that monitors desired segments of the controlled process in real-time and aids the operator in timely detection of the recurring critical situation based on the initial operator's observation. The proposed solution does not rely on machine learning or any demanding computational task and therefore can coexist with existing control systems without the need for additional computational power. Furthermore, there is no need for additional client software on any working station used for process control as it is accessed via the web browser.

A deductive system for database normalization is implemented by using a Flora-2 reasoning engine. The system allows for checking a relational schema up to Boyce- Codd normal form (BCNF) and functional independent normal form (FINF). Examples of system usage are presented and discussed.

Quality and usability of Web applications are considered to be key aspects of their success. If these aspects are not adequately represented in a Web application, or if they are not appropriately combined, there will be little to prevent the users from browsing further in search of an application that will more effectively satisfy their needs. However, the main challenge is to identify key attributes that will retain users on a Web application longer or influence their decision to visit it again. There are many frameworks and methodologies that deal with this issue but very few of them have an emphasis on assessing the quality and usability of Web 2.0 applications. This paper contains a critical review of previous research in the field of Web quality assessment. It provides the theoretical basis for the development of a set of attributes that should be considered when measuring the quality of Web 2.0 applications.

Analysis and design of algorithms is a great challenge for both computer and information science students. Fear of programming, lack of interest, and the abstract nature of the programming concepts are the main cause of the high drop out and failure rates in introductory programming courses. With an aim to motivate and help students, many researchers have proposed different kinds of tools. Although it has been reported that some of these tools have a positive impact on gaining programming skills, the problem still remains mostly unsolved. This paper describes ViSA, a tool for the visualization of sorting algorithms. ViSA is an easy-to-setup and fully automatic visualization system with step-by-step explanations and comparison of sorting algorithms. Design principles and technical structure of the visualization system as well as its practical implications and educational benefits are presented and discussed.
