Software para la automatización de formatos académicos de prácticas profesionales y vinculación de la Universidad Católica de Cuenca
(Universidad Católica de Cuenca., 2025) León Beltrán, Marlon Santiago; Cuenca, Juan Pablo; 0107356511
The Catholic University of Cuenca is undergoing an era of technological innovation and process automation. Currently, it faces a significant challenge in managing the forms related to pre-professional internships, community service, and internal internships, which are still managed manually. This involves a large amount of paperwork and administrative processes, which causes delays both in the preparation of the forms by the students and in their review and approval by the teaching staff. This situation significantly affects operational efficiency, increases the administrative burden, and complicates the timely monitoring of student progress in these key curricular components. Therefore, it is evident that an advanced digital solution is required for the comprehensive management of these documents. This need is justified by the limitations of the current manual handling system, which is not only prone to errors but also lacks agility and traceability in dynamic educational environments. The development of software based on digital technologies, process automation, and cloud storage would enable a substantial improvement in work efficiency, ensuring greater transparency, security, and accessibility in document management. This digital transformation would not only optimize the time of students and teachers, but also raise the quality of academic and administrative processes, aligning with the requirements of modern and efficient higher education.

Evaluación del Efecto Combinado de la menaquinona-4 y L-carnitina sobre la Crioconservación del Semen Ovino
(Universidad Católica de Cuenca., 2025) Lema Guamán, María Flor; Moscoso Piedra, Andrés Leonardo; 0302305750
This biological research was conducted at the Reproduction Laboratory of the Universidad Católica de Cuenca, Ecuador, and focused on the cryopreservation of ram genetics, a process that negatively affects sperm functionality and viability due primarily to oxidative stress (OS) generated during freezing and thawing, as a consequence of the biochemical properties of the sperm plasma membrane. The study evaluated the post-thaw effect of L-Carnitine (1 mM) and Menaquinone-4 (1 mM), individually and in combination (1 mM × 1 mM), on ovine semen collected from a single ram, assessing vitality, viability, plasma membrane integrity, mitochondrial activity, and sperm kinetics using the Computer Assisted Sperm Analysis (CASA) system. Significant differences (p<0.05) were detected in several parameters, where the membrane integrity (%HOST, p=0.002) indicated a negative effect associated with ionic imbalance, the high immotile index (p=0.047) reflected excess additives in the extender, and the reduced linearity (%LIN, p=0.005) was related to the absence of cofactors supporting antioxidant activity. The high variability among internal and external factors (replicates) affecting sperm performance suggests that antioxidant dosage and exposure times must be considered to better understand their synergistic or antagonistic biological effects under oxidative stress conditions.

Evaluación del efecto combinado de Coenzima Q10 y L-Carnitina sobre la crioconservación de semen ovino
(Universidad Católica de Cuenca., 2025) Guamarringra Sánchez, Ibel Carolina; Moscoso Piedra, Andrés Leonardo; 0925224958
One of the main limitations for cryopreservation of ram semen as part of veterinary science is its high sensitivity to reactive oxygen species (ROS). Spermatozoa are constantly exposed to this damage due to changes in temperature, light, and their own biochemical nature, which affects their viability, motility, and functionality. This highlights the need to use additives with antioxidant properties, given their apparent positive impact on the preservation of animal genetics. The objective of this study was to evaluate the combined effect of adding Coenzyme Q10 (0.05 mM), a widely used antioxidant in reproductive supplementation, and L-Carnitine (1 mM), an amino acid derivative with functions in fatty acid transport and antioxidant activity, to the freezing medium. For this purpose, eight semen samples were collected from a single ram, and the treatments included CoQ10 (0.05 mM), L-Carnitine (1 mM), both molecules combined at the same doses, and a control (Tryladil). Motility, viability, membrane integrity and functionality, as well as mitochondrial activity, sperm progressivity, and kinematics were assessed using the C.A.S.A. (Computer Assisted Sperm Analysis System). The results showed negative effects (p<0.05) of the combined solution on all sperm quality parameters compared to the control and L-Carnitine alone, while no significant differences (p>0.05) were observed in sperm kinematics. It is therefore concluded that the combined addition of L-Carnitine and CoQ10 to the freezing medium alters the redox balance at the sperm level and reduces fertility potential.

Sufrimiento fetal agudo: PH fetal del cuero cabelludo intraparto
(Universidad Católica de Cuenca., 2025) Almestar Japon, Katherine Fernanda; Duran Vega , Oswaldo Jair; 0107149585
Introduction: Acute fetal distress involves a series of obstetric complications, altering the normal course of a eutocic delivery. Fetal scalp pH testing is of utmost importance to determine if the fetus is receiving enough oxygen, which could be useful for the early detection of acute fetal distress. Literature Review: Examination of the fetal scalp is very important to corroborate fetal well-being. It helps us with the early diagnosis of acute fetal distress, thereby preventing irreversible neurological damage. Conclusions: Intrapartum fetal scalp sampling is performed as a complementary method, being a great indicator of fetal hypoxia. With proper intervention, it plays a crucial role in the early diagnosis of fetal distress.

La ludoteca como estrategia didáctica en el desarrollo de la creatividad en niños de educación inicial
(Universidad Católica de Cuenca., 2025) Borga López , Ana María; Salinas Salinas , Diego Armando; 0106322555
The toy library, as an innovative didactic strategy, enhances children's creativity through free play, promoting divergent thinking, emotional expression, and active learning in early childhood education. This research was conducted to determine the implementation of the toy library as a didactic strategy to enhance the development of creativity in early childhood education, in order to understand its impact on the cognitive, emotional, and social aspects of children. The methodology used was qualitative, based on a bibliographic-documentary design using digital databases of the Catholic University of Cuenca. The analyzed studies highlight how toy libraries and playrooms stimulate children's creativity, socialization, and autonomy. Through play, they favor integral development in diverse educational and community contexts. It is concluded that the toy library enhances divergent thinking, empathy, and children's self-esteem. Through free and guided play, it fosters creativity, socialization, and emotional development, highlighting the essential role of the mediator.
