Information and communication technology is very important both for teacher training and for delivering quality education. Therefore, university graduates must have a level of qualification in digital competencies suitable for their entry into the world of work. The research analyzes various aspects related to the use of technological resources by graduate students who were currently studying for a university master’s degree in compulsory secondary education, and the relationship between their use based on gender and/or age. A descriptive cross-sectional survey is carried out. We use an ad hoc questionnaire that shows acceptable reliability. The results show that graduate students make traditional use of ICT—both for searching for information and using digital resources for teaching. Moreover, differences were found based on gender and age regarding participants’ perception of their digital competence.

The circumstances arising from the exceptional situation caused by the COVID-19 pandemic have affected all socioeconomic areas in the last two years. The field of Education has not been an exception, and the management of the situation seems to have caused an increase in the level of perceived stress of university students. On this basis, this research that aims, first, to analyze the student’s level of perceived stress during the de-escalation and return to normality period, secondly, to evaluate its relationship with life satisfaction and, finally, to detect the students’ needs in stress management, has been developed. An exploratory-descriptive study of quantitative and cross-sectional nature has been carried out. A total of 222 university students of the Childhood and Primary Education Degrees of the University of Jaén (Spain) have participated. The instruments, Perceived Stress Scale (PSS) and Satisfaction with Life Scale (SWLS) have been used. The results show a moderate and partial relationship among the dimensions of the used instruments. The obtained coefficients of determination are, Academic Performance (r² = 0.019) and Life Satisfaction (r² = 0.402), with a mean square error (SRMR) of 0.079. These findings show the need to develop actions within the university training program in effective stress management strategies.

The main objective of this paper is to obtain extra virgin olive oils (EVOOs) which are balanced in volatile and phenolic compounds. An experimental design was performed and response surface methodology was applied. The factors for malaxation were: temperature 20-40 °C, time 30-90 min, and hole diameter of hammer-crusher 4.5-6.5 mm. The results show that high temperatures and small hole diameter must be used in order to obtain a higher content in phenolic compounds, while for volatile compounds a low temperature and large hole diameter must be used. The models predict that the best and more balanced EVOO are obtained with the hole diameter of greater size and a medium-low temperature. Thus, for a hammer-crusher hole diameter of 6.5 mm 337 and 356 mg/kg total HPLC phenols were obtained for malaxation temperature of 20 and 25 °C, respectively and, likewise, 12.7 and 11.5 mg/kg total LOX volatiles.

This work is part of a broader investigation whose main objective is to determine the domain and preferences of the students of the Childhood Education Degree of the University of Jaén regarding digital competence. The research was focused on the “use of digital resources” dimension and was developed under a quantitative and descriptive methodology, of basic type and non-experimental cross-sectional design. We worked with a sample of 135 students from the four courses of the Childhood Education Degree of the University of Jaén, who answered a developed questionnaire voluntarily and anonymously. Data collection was carried out using a virtual questionnaire on the Google Form platform. In addition, the measurement instrument was considered valid and reliable, having obtained a Cronbach’s alpha coefficient (α) of 0.925 and a Kaiser–Meyer–Olkin sampling adequacy index (KMO) of 7.741. The results show that there are no significant differences based on the independent variables studied among most of the analyzed items. The use of ICT is beneficial for students’ participation in research.
