    ("Universo Sur", de la Universidad de Cienfuegos, publica la Revista Conrado , 06-2023) Sucari León, Reynaldo; Aroquipa Durán, Yolanda; Ponce Pardo, John Eloy; Chiri Saravia, Paulo Cesar
    El estudio tuvo como objetivo, determinar la influencia de la actitud, motivación y la ansiedad en el rendimiento académico de los estudiantes. Se siguió una metodología cuantitativa, se tuvo un diseño no experimental, correlacional causal y de corte transversal. Se contó con una muestra de 221 estudiantes, a quienes se aplicaron tres cuestionarios y se tomó en cuenta los promedios de notas del último trimestre, en el análisis estadístico se usó el descriptivo e inferencial con tablas de contingencias y el análisis de regresión logística ordinal. En los resultados se encontró que el 42.5% de los estudiantes presentaron una actitud regular hacia el estudio, un 52.9% de estudiantes presentan una motivación media hacia el estudio, así mismo un 52.9% de estudiantes presentaron una ansiedad moderada para el estudio, y respecto al rendimiento académico el 56.6% de estudiantes alcanzaron un nivel regular. Finalmente se concluye, que existe una influencia significativa de la actitud, motivación y la ansiedad en el rendimiento académico de los estudiantes, presentando una dependencia de hasta un 63.1% según el coeficiente de Nagelkerke.

    Bioactive Compounds and Sensory Quality in Chips of Native Potato Clones (Solanum tuberosum spp. andigena) Grown in the High Andean Region of PERU
    (Multidisciplinary Digital Publishing Institute. Food, 2023-06-28) Gutiérrez Gómez, Edgar; Ligarda Samanez, Carlos A.; Palomino Rincón, Henry; Choque Quispe, David; Moscoso Moscoso, Elibet; Arévalo Quijano, José C.; Huamán Carrión, Mary L.; Quispe Quezada, Uriel Rigoberto; Muñoz Saenz, Jenny C.; Cabel Moscoso, Domingo J.; Sucari León, Reynaldo; Aroquipa Durán, Yolanda; García Espinoza, Antonina J.
    Native potatoes (Solanum tuberosum spp. andigena) have diverse pigments and are cultivated in Peru’s high Andean regions; they are characterized by containing bioactive compounds that prevent various degenerative diseases. The study aimed to evaluate the physicochemical and sensory quality in chips of native potato clones grown at 3496 m altitude, for which the potatoes were cut into slices and fried in extra virgin olive oil at 180 °C for 200 s. This was determined by proximal analysis, reducing sugars, minerals, color, antioxidant capacity (AC), total phenolic compounds (TPC), and anthocyanins in fresh and chips; an instrumental characterization by FTIR and SEM and sensory tests were also performed. The native potatoes presented low moisture and reduced sugar contents; when frying, their bioactive properties improved, increasing AC, TPC, and trace elements, such as K, Mg, Ca, P, Fe, and Zn. To conclude, fresh clones have high yields in the field and are an essential source of nutrients and bioactive; the salt-free chips of clone B presented better physicochemical properties and greater sensory acceptance, closely followed by clone A. Both clones could be used as raw material by food companies that produce snacks to benefit high Andean agricultural producers.

    Physicochemical and Sensory Evaluation of Gummy Candies Fortified with Microcapsules of Guinea Pig (Cavia porcellus) Blood Erythrocytes and Tumbo (Passiflora tarminiana) Juice
    (Multidisciplinary Digital Publishing Institute. Applied sciences, 2025-06-17) Sucari León, Reynaldo; Ligarda Samanez, Carlos A.; Villano Limache, Eliana; Pichihua Oscco, Williams; Choque Quispe, David; Calderón Huamaní, Dante Fermín; De la Cruz, Germán; Luciano Alipio, Rober; Calsina Ponce, Wilber Cesar; Aroquipa Durán, Yolanda; Campos Huamaní, María José Victoria
    Recently, interest in developing functional foods that promote health has grown significantly. This study aimed to evaluate the feasibility of microencapsulating guinea pig blood erythrocytes by vacuum drying and incorporating them into gummies fortified with tumbo juice. Physicochemical analysis (proximate analysis, iron content, color, pH, soluble solids, and particle size) and functional group analysis by Fourier transform infrared spectrophotometry were performed on three formulations of gummy candy ith added encapsulated erythrocytes from guinea pig blood (EEGPB): F1 (4% EEGPB), F2 (5% EEGPB), and F3 (6% EEGPB). The results showed a significant decrease in the moisture content (52.02% in F1 to 43.27% in F3) and increases in protein (11.44% in F3) and iron (2.63 mg Fe/g in F3) contents when higher EEGPB levels were used. Sensory evaluation revealed that F3 was the most acceptable formulation in terms of taste, aroma, and texture, with no significant differences in color. FTIR analysis confirmed physical incorporation with no chemical interactions between ingredients. These results demonstrate that the encapsulation of erythrocytes by vacuum drying not only preserves the bioactive compounds but also improves the organoleptic properties of the gummies, making them an attractive product for consumers. In conclusion, this technique is effective for fortifying functional foods and has potential application in other food products. This approach represents a significant advance in the development of innovative functional foods.

    Technological Innovations and Circular Economy in the Valorization of Agri-Food By-Products: Advances, Challenges and Perspectives
    (Multidisciplinary Digital Publishing Institute. Food, 2025-05-30) Sucari León, Reynaldo; Ligarda Samanez, Carlos A.; Huamán Carrión, Mary L.; Calsina Ponce, Wilber Cesar; Germán De la Cruz; Calderón Huamaní, Dante Fermín; Cabel Moscoso, Domingo J.; Garcia Espinoza, Antonina J.; Aroquipa Durán, Yolanda; Muñoz Saenz, Jenny C.; Muñoz Melgarejo, Mauricio; Jilaja Carita, Enoc E.
    The valorization of agri-food by-products is a critical pathway toward building sustainable food systems, reducing waste, and advancing the circular economy. This review aims to identify recent advances, key challenges, and future perspectives in this field. We conducted a critical and systematic synthesis of 159 peer-reviewed studies (2019–2025) selected based on quality and thematic relevance from leading international databases. The analysis focuses on emerging technologies such as ultrasound-assisted extraction, microencapsulation, spray drying, lyophilization, deep eutectic solvents, and colloidal systems, emphasizing their efficiency in recovering bioactive compounds from agro-industrial by-products. Significant challenges include industrial scalability, economic feasibility, regulatory compliance, and consumer acceptance. This paper also discusses current applications in functional foods and nutraceuticals, outlining promising directions for the sector. Although challenges remain, the findings offer valuable insights for researchers, industry, and policymakers aiming to foster sustainable innovation and implement strategies aligned with circular economy principles.

    Technological Innovations in Sustainable Civil Engineering: Advanced Materials, Resilient Design, and Digital Tools
    (Multidisciplinary Digital Publishing Institute. Sustainability, 2025-09-29) Sucari León, Reynaldo; Huamán Carrión, Mary L.; Cabel Moscoso, Domingo J.; Muñoz Sáenz, Doris Marlene; Martinez Hernandez, Jaime Antonio; Garcia Espinoza, Antonina J.; Calderón Huamaní, Dante Fermín; Carrasco Badajoz, Carlos; Darwin Pino Cordero; Aroquipa Durán, Yolanda
    Civil engineering today faces the challenge of responding to climate change, rapid urbanization, and the need to reduce environmental impacts. These factors drive the search for more sustainable approaches and the adoption of digital technologies. This article addresses three principal dimensions: advanced low-impact materials, resilient structural designs, and digital tools applied throughout the infrastructure life cycle. To this end, a systematic search was conducted considering studies published between 2020 and 2025, including both experimental and review works. The results show that materials such as geopolymers, biopolymers, natural fibers, and nanocomposites can significantly reduce the carbon footprint; however, they still face regulatory, cost, and adoption barriers. Likewise, modular, adaptable, and performance-based design proposals enhance infrastructure resilience against extreme climate events. Finally, digital tools such as Building Information Modeling, digital twins, artificial intelligence, the Internet of Things, and 3D printing provide improvements in planning, construction, and maintenance, though with limitations related to interoperability, investment, and training. In conclusion, the integration of materials, design, and digitalization presents a promising pathway toward safer, more resilient, and sustainable infrastructure, aligning with the Sustainable Development Goals and the concept of smart cities.
