    Clima organizacional y satisfacción laboral del personal administrativo de la Municipalidad Distrital de Vilquechico - 2024
    (Universidad Nacional de Juliaca, 2025) Chuquimamani Quispe, Rut Noemi; Tito Humpiri, Juan Manuel
    El clima organizacional y la satisfacción laboral son factores clave para la eficiencia de los gobiernos locales. Sin embargo, en distritos rurales como Vilquechico, región Puno, escasean diagnósticos sistemáticos que orienten intervenciones de mejora institucional. Ante ello, se determinó la relación entre el clima organizacional y la satisfacción laboral del personal administrativo de la Municipalidad Distrital de Vilquechico - 2024 mediante un enfoque cuantitativo con diseño descriptivo-correlacional y corte transversal. Se encuestó a la totalidad de trabajadores administrativos (N = 45) con instrumentos previamente validados (α ≥ 0.80), incluyendo estadística descriptiva y la prueba de correlación de Spearman. Los resultados revelaron que tanto el clima organizacional (73.3%) como la satisfacción laboral (75.6%) se sitúan predominantemente en un nivel medio. A pesar de este equilibrio intermedio, la asociación entre ambas variables fue significativa y alta (ρ = 0.876; p < 0.001). Entre las dimensiones del clima organizacional, la estabilidad laboral (ρ = 0.703) y el sentido de pertenencia (ρ = 0.694) mostraron mayor fuerza de asociación con la satisfacción global y con la satisfacción con los compañeros, respectivamente. Por el contrario, las mayores debilidades se concentraron en el estilo de dirección, la equidad retributiva y la disponibilidad de recursos, lo que sugiere la necesidad de intervenciones estratégicas en estos componentes. Se concluyó que mejorar la calidad del liderazgo, fortalecer la justicia retributiva y garantizar la provisión de recursos son condiciones clave para elevar tanto el bienestar del personal como el rendimiento institucional.

    Phenolic compounds versus SARS-CoV-2: An update on the main findings against COVID-19
    (Elsevier, 2022-09-19) Tirado Kulieva, Vicente Amirpasha; Hernández Martínez, Ernesto; Choque Rivera, Tania Jakeline
    Phenolic compounds are essential due to their antioxidant activity and high antiviral potential. In this context, this review reports the main findings on the effect of phenolic compounds (PCs) against SARS-CoV-2 virus. First, the proven activity of PCs against different human viruses is briefly detailed, which serves as a starting point to study their anti-COVID-19 potential. SARS-CoV-2 targets (its proteins) are defined. Findings from in silico, in vitro and in vivo studies of a wide variety of phenolic compounds are shown, emphasizing their mechanism of action, which is fundamental for drug design. Furthermore, clinical trials have demonstrated the effectiveness of PCs in the prevention and as a possible therapeutic management against COVID-19.

    Analysis of the ultraviolet Index in the region of Puno, Peru
    (LACCEI, 2023) Taipe Huaman, Ciro William; Mendoza Mamani, Eva Genoveva; Gallegos Ramos, Julio Rumualdo; Flores Laime, Hugo Hernan; Enriquez Mamani, Vitaliano; Laura Huanca, Julio Cesar; Choque Rivera, Tania Jakeline
    The work had the objective of analyzing the values of the ultraviolet index in the Puno region, for which it has been considered a point of reference in the thirteen provinces. To obtain ultraviolet index values, data from the weather station of the city of Puno for the period 2016-2021 has been considered and with this obtain a correction equation for the data obtained from the Giovanni NASA website and thus obtain maximum daily values for the Puno region. A theoretical model has been considered to obtain the ultraviolet index, which is for clear sky conditions. The evaluation statistics used are the standard error and the linear correlation coefficient between the estimated data and values measured by the weather station. It is concluded that it is possible to obtain UV index values for the city of Puno with a reliability of 95% and an error of 0.8, and for the Puno region it is possible to obtain UV index values by means of the correction equation, where the very high and extreme UV index values occur in the summer season.

    Conversion of Lignocellulose Biomass to Bioenergy Through Nanobiotechnology
    (Journal of Sustainable Development of Energy, Water and Environment Systems, 2023) Al Zubi, Mohammad Ahmed; Ore Areche, Franklin; Morales Alberto, Manuel Nicolás; Cotrina Cabello, Guillermo Gomer; Sobrado Gomez, Angel; Legua Cárdenas, José Antonio; Llanos Zevallos, Manuel; Lijarza Llanos, Yaseth Yohely; Morsy, Kareem; Quincho Astete, Jhon Adolfo; Castañeda Chirre, Elvira Teófila; Choque Rivera, Tania Jakeline; Vivanco Aguilar, Salomón; Sánchez Araujo, Víctor Guillermo; Quispe Vidalon, Daniel
    The growing global demand for energy, particularly petroleum-based fuels, has stimulated a long-term quest for an optimal source of sustainable energy. Lignocellulosic biomass has shown to be an effective source of renewable bioenergy due to the high chemical energy it contains and the 75 percent carbohydrate content of cellulose and hemicellulose. This review examines how nanotechnology can transform biomass into energy through novel, environmentally sustainable approaches. It discusses various conversion techniques, nanoparticle applications, and enzyme immobilization strategies while addressing both opportunities and constraints in lignocellulose biomass conversion for bioenergy production.

    Predictors of Food Handling Practices of Massive Food Catering Establishment in Ethiopia: Systematic Review and Meta-Analysis
    (Current Research in Nutrition and Food Science, 2023) Ketema, Sisay; Ore Areche, Franklin; Pacovilca-Alejo, Olga Vicentina; Zea Montesinos, Cesar Cipriano; Choque Rivera, Tania Jakeline; Taipe Huaman, Ciro William; Corilla Flores, Denis Dante; Camayo-Lapa, Becquer Frauberth; Porras-Roque, María Soledad; Sumarriva-Bustinza, Liliana Asunción; Zela Payi, Nelly Olga; Sobrado Gómez, Angel; Llanos Zevallos, Manuel; Yaulilahua-Huacho, Russbelt
    Food borne disease is one among a series of public health problems globally due to poor food handling practices from production to service. This study aimed to find out the predictors of food handling practice among massive food catering establishments in Ethiopia. Different search engines were used and extraction of the data was done. Random-effects meta-analysis model was used to analyze the pooled value. DerSimonian – Laird method was used to estimate the study variance. The Cochrane's Q test (chi-square) and I2(%) were used to identify the heterogeneity of the studies. The overall pooled prevalence of good food handling practice was 50 (95% CI:43%, 57%). Predictors such as good Knowledge (AOR: 2.6(95% CI: 1.90, 3.18), Training (AOR: 3.16(95% CI: 2.2, 4.44), Medical cheek up (AOR: 6.76(95% CI: 4.49, 10.18), Supervision (AOR: 3.76(95% CI:2.12, 6.66), Experience (AOR: 2.00(95% CI: 1.52, 2.79) and Water basin availability (AOR: 2.06(95% CI:1.94, 3.83) were significant factors of food handling practice in massive food catering establishment in Ethiopia. Food handling practice was low and predictors of food handling including, knowledge, Training, Medical checkup, Supervision, Experience, and water availability were statistically significant. Therefore, Policymakers and facilities owners, give better or higher prominence to improving the status of food handling practices with design intervention strategies. In conclusion, comparatively low levels of good food handling practice were found among Ethiopian food handlers working in public food establishment.
