The impacts of environmental pollution are potentially irreversible and have become a major concern for society. Faced with this reality, the purpose of this study is to identify what type of flexible packaging material used in the food industry creates less pollution. The Leopold Matrix was employed to quantitatively assess the life cycle of plastic and paper packaging, using information from various scientific articles and peer-reviewed indexed journals. The interactions between physical, biological, and socioeconomic elements were established for each action in the life cycle of the packages. The results showed that flexible plastic packaging pollutes 16 percent more in the physical aspect concerning soil and water pollution than paper packaging, which has a more significant impact on air pollution. Regarding the biological aspect, plastic pollutes 63 percent more than paper in terms ...

“The impacts of environmental pollution are potentially irreversible and have become a major concern for society. Faced with this reality, the purpose of this research is to identify which type of flexible packaging material used in the food industry creates less pollution. The Leopold Matrix was applied to assess in quantitative terms the life cycle of plastic and paper packaging, using information from various scientific articles and peer-reviewed indexed journals. The interactions between physical, biological, and socioeconomic elements were established for each action in the life cycle of the packages. The results showed evidence that flexible plastic packaging pollutes 16% more in the physical aspect concerning soil and water pollution than paper packaging, which has a more significant impact on air pollution. Regarding the biological aspect, plastic pollutes 63% more than paper w...

Se realizó una investigación de tipo aplicada, de nivel descriptivo y de diseño cuasi experimental con el objetivo de reducir el tiempo del servicio de mantenimiento automotriz en el Taller Soluciones MAU 93 S.A.C., el cual se encarga de brindar servicio preventivo y correctivo en general. También, se procedió a realizar un diagnóstico inicial en donde se determinaron las causas principales de la demora en el servicio de mantenimiento. Luego, se desarrolló la implementación de la metodología 5S que consistió en el ordenamiento del taller, la clasificación de las herramientas e insumos, la limpieza del lugar de trabajo, la estandarización del proceso de mantenimiento automotriz y la implementación de un código de disciplina y capacitación para los trabajadores. Como indicadores, se tomaron los porcentajes del área recuperada, la reducción del tiempo de búsqueda de la her...

Objectives: to determine the relationship between obesity and the TG / HDL index in patients treated at the endocrinology outpatient service of the Sergio Bernales national hospital in 2018. Methods: the study was observational, analytical, case-control type not matched to ratio of 4: 1, with a total of 288 study subjects, 230 controls and 58 cases who met the selection criteria, involved the patients treated in the endocrinology outpatient service. The sample was simple random, the variables were included: Sex, age, Body mass index, Total cholesterol, Total triglycerides, HDL-c, LDL-c, TG / HDL index. A logistic regression model was used to obtain an Odds Ratio for the strength of association. Results: The relative frequency of obesity was 65.52% and 29.13%, for cases and controls respectively, in turn a statistical significance with Fisher's exact test, P-value 0.000. A bivariate logis...
