The purpose of this paper is to present the attitude of teachers from Romanian undergraduate education system towards digital solutions in the COVID-19 era and post COVID-19 era. Moreover, one of the main objectives is to analyze teachers' openness to the further integration of mobile solutions in Romanian undergraduate educational system. This paper relies on a case study about the way digital solutions were integrated in the teaching process during the pandemic and if and how they will be integrated in the post COVID-19 era. The data was collected through a questionnaire spread among teachers from all the levels of undergraduate educational system. After the analysis, it was identified that digital solutions were a great help to undergo the teaching process during the pandemic and, once discovering their benefits, the teachers are willing to further make use of them. Nevertheless, it is teachers' strong belief that the traditional educational system can never be totally replaced by an online/mobile-based system, but that the two can coexist for the improvement of the pupils' education and engagement. Overall, this paper contributes to the literature by offering an insight of the way digitalization of Romanian undergraduate education systems is viewed by one of the main actors of the learning process, the teachers. While digitalization in university context was highly discussed, the undergraduate context was not paid the same attention and this study aims to increase the awareness that the undergraduate educational system needs solutions for digitalization too.

The purpose of this paper is to examine the security vulnerabilities that may appear in an adaptive mobile learning system, as well as to present ways to prevent security breaches in this type of learning systems. Moreover, this paper has the objective to present a possible solution consisting of an adaptive ubiquitous learning system that can bypass the most frequent security issues that may appear in mobile learning systems. This paper relies on a study of the three most used mobile applications in learning foreign languages, considered also being the best on the market. Those applications were submitted to security scan in order to identify their vulnerabilities. After this analysis, several categories of vulnerabilities have been identified, in addition to their cause. Besides scanning against OWASP Mobile Top 10 vulnerabilities, the study determines that it may exist some security breaches in relation with the external communication the application has. Based on the results from the security scan, a new solution that has the objective to prevent as many discovered vulnerabilities as possible is to be implemented. Overall, this paper contributes to the literature by revealing security questions that appear in some of the most used mobile application for learning a foreign language at the moment. Moreover, it will describe a prototype of a possible first adaptive ubiquitous learning systems, free from security threats, that allow Romanian users to obtain basic knowledge for speaking Swedish.
