Analysis of Mental Health and Accelerated Use of Technologies: A Psychological Study among Chilean Workers

Victor Felipe Castillo Riquelme — 2026-07-09

Technostress is an emerging psychosocial risk associated with the accelerated adoption of technologies in the workplace. Although its impact on mental health has been documented in the educational sector, there is limited evidence in Chile regarding other occupational sectors. This study examined the relationship between technostress and mental health, specifically anxiety, depression, and stress, in 178 Chilean workers, using a cross-sectional correlational-predictive design. The Technostress Creators Scale, RED-TIC, and DASS-21 were administered, and mean comparisons, correlations, network analysis, and multiple regressions were performed. Sociodemographic differences were limited, with higher techno-insecurity observed in men and higher techno-intrusion among young workers and fee-based workers. Technostress manifestations showed moderate associations with mental health, exceeding those observed for technostress creators. Techno-intrusion predicted distress, while technological skepticism predicted depression. The findings suggest the need to incorporate technostress as a psychosocial risk and to further explore the mediation mechanisms among the variables.

Concentrate of Omega-3 Fatty Acids EPA and DHA Obtained by Winterization of Crude Anchovy Oil (Engraulis ringen)

Pascual Alejandro Martinez Alban — 2026-07-11

This study evaluated the production of a concentrate of omega-3 fatty acids EPA and DHA through the winterization of crude anchovy oil (Engraulis ringens). Two samples obtained from processing plants in Chimbote and Callao, Peru, were subjected to temperatures of 22, 10, 5, 0, and −5 °C for 96 h. Free acidity and iodine value were determined according to Peruvian technical standards, while the fatty acid profile was analyzed by gas chromatography. The samples treated at 0 and −5 °C crystallized completely and were therefore excluded from further analysis. The treatment at 5 °C produced the highest enrichment of EPA and DHA, reaching combined contents of 39.99% and 40.19% in the Chimbote and Callao samples, respectively. In addition, free acidity remained within regulatory limits, and the iodine value increased, confirming that winterization is an efficient alternative for concentrating omega-3 fatty acids while preserving oil quality.
