El presente trabajo tiene como objetivo principal determinar el impacto de un sistema de gestión logística en los costos logísticos en el área de logística de la empresa Bambú Retail E.I.R.L. Para ello, se desarrolló el diagnostico actual haciendo uso de las siguientes técnicas: Diagrama de Ishikawa, encuesta, Diagrama de Pareto, Matriz de priorización e indicadores, con esto se logró identificar las perdidas actuales en el área de logística. Luego se desarrolla la propuesta de mejora para cada causa, empezando por el sistema ABC para una mejor gestión de inventarios, después un Plan de Capacitación para un mejor control de calidad de productos y un mejor conocimiento sobre gestión logística y aplicación de las 5S para mejor orden y limpieza de su almacén. Finalmente se realizó un análisis económico financiero para comprobar si el estudio realizado es factible de aplicar, teniendo como resultado un VAN de S/ 52,274.78, TIR de 56.25% y B/C de S/2.80, lo cual señala que la propuesta de aplicación de herramientas es factible, lo cual redujo los costos logísticos de S/ 41,242.90 a S/ 14,114.71 obteniendo un beneficio significativo de S/ 27,128.19 anual, en el área de logística de la empresa Bambú Retail E.I.R.L

Hormonal Regulation in Different Varieties of Chenopodium quinoa Willd. Exposed to Short Acute UV-B Irradiation

Increased ultraviolet-B (UV-B) due to global change can affect plant development and metabolism. Quinoa tolerates extreme conditions including high UV levels. However, the physiological mechanisms behind its abiotic stress tolerance are unclear, especially those related to UV-B. We previously demonstrated that 9.12 kJ m−2 d−1 may induce UV-B-specific signaling while 18.24 kJ m−2 d−1 promotes a UV-B-independent response. Here, we explored the effects of these UV-B doses on hormonal regulation linked to plant morphology and defense among diverse varieties. Changes in fluorescence parameters of photosystem II, flavonoids and hormones (indoleacetic acid (IAA), jasmonic acid (JA), abscisic acid (ABA) and salicylic acid (SA)) were surveyed under controlled conditions. Here, we showed that the sensitivity to short acute UV-B doses in varieties from different habitats is influenced by their parental lines and breeding time. UV-B sensitivity does not necessarily correlate with quinoa’s geographical distribution. The role of flavonoids in the UV-B response seems to be different depending on varieties. Moreover, we found that the extent of changes in JA and SA correlate with UV-B tolerance, while the increase of ABA was mainly related to UV-B stress.Peer reviewe

Satisfacción laboral en los colaboradores del Centro Médico Villa María en el distrito de San Juan de Miraflores - 2022

La presente investigación tiene como objetivo general describir los factores más importantes en la satisfacción laboral en los colaboradores del Centro Médico Villa María en el distrito de San Juan de Miraflores – 2022. Para su desarrollo se utilizó la metodología de investigación tipo descriptiva cuantitativa, de diseño no experimental y de forma transversal. La población fue censal utilizando a los 40 colaboradores del Centro Médico. Se utilizó la técnica de encuesta y se aplicó como instrumento un cuestionario elaborado y validado por la Psicóloga Sonia Palma Carrillo (2005) en el que basa cuatro dimensiones Reconocimiento Personal y/o social, Significación de la Tarea, Condiciones de Trabajo y Beneficios Económicos. Se obtuvieron como resultados en la investigación que los factores que intervienen en la satisfacción con mayor impacto solo fue la dimensión Significación de la tarea con un 37,5%, en segundo lugar, con mediano impacto condiciones de trabajo con el 27,5%, para finalizar con menor efecto fueron las dimensiones reconocimiento personal y/o social con 25% en el nivel medio y otro 25% en el nivel bajo, beneficios económicos con un 22,5% encontrándose de la misma manera en el mismo nivel

Assessment of transrectal ultrasonography for detection of ovarian follicles in hair sheep

This study evaluated the accuracy of transrectal ultrasonography (US) for the determination of ovarian follicles in hair sheep. Number and size of follicles in 24 ovaries (n= 12 ewes) were determined using an ultrasound machine (Aloka SSD 500), fitted with a 7.5 MHz transrectal probe. The ovaries were collected just after US, for measurement of the number and size of follicles (postmortem findings; PM). There were no differences in the number of small (2 to 2.9 mm), medium (3 to 3.9 mm), large (≥ 4 mm) and total follicles/ovary as detected by US and PM (1.3 ± 0.3 vs 1.6 ± 0.3; 0.5 ± 0.2 vs 0.8 ± 0.2; 0.5 ± 0.2 vs 0.5 ± 0.2; and 2.3 ± 0.3 vs 2.9 ± 0.4; respectively). The sensitivity and predictive value of US for detection of follicles in each category were 71.1, and 87%; 68.4, and 100%; 91.7, and 100%; 73.9, and 92.7%, respectively; the correlation coefficiennts (r) for number of small, medium, large and total follicles being 0.75, 0.83, 0.96 and 0,75 (P<0.001), respectively. It was concluded that US is an efficient tool for detection and measurement of ovarian follicles in studies of the reproductive physiology in hair ewes
