The objective of the research work, was to analyze the curriculum of the programs from “Universidad Francisco de Paula Santander” in San José de Cucuta, Colombia. The sample was participatory non-probability, with the participation of 200 students from Catatumbo and university student’s, both from the different semesters and documents curriculums. A mixed study of sequential explanatory design was applied. In the first quantitative phase, the results were obtained by applying a digital questionnaire to the students. The data were analyzed using the observation guide for their respective analysis. The results of both phases were merged by the contrasting method. The conclusions demonstrate the importance of curriculum for training in research and innovation and critical thinking, curriculum for the creation, adaptation and/or use of communication and information technologies, curriculum for social inclusion in the university.

El pimentón (Capsicum annuum L) es uno de los cultivos de hortalizas más importantes y ampliamente cultivados a nivel mundial. Este estudio determinó la eficacia del test tetrazolio para obtener la viabilidad de semillas de C. annuum. De manera que, semillas de C. annuum se expusieron a dos concentraciones (1% y 0.5%) de tetrazolio y dos tiempos de exposición (24 y 48horas). Ulteriormente, utilizando un microscopio estereoscopio se valoró la tinción de las semillas, estimando como semillas viables las que presentaron coloración roja en el embrión. Por consiguiente, se obtuvieron diferencias estadísticamente significativas (P ≤ 0,05: Tukey HSD) en  el tratamiento T4 (0.5 %, 48h) con un 99% de viabilidad. Así mismo, los tratamientos T1 (1 %, 24h) y T2 (0.5 %, 24h) no presentaron diferencias entre sí, siendo el porcentaje de viabilidad 89% y 91% respectivamente. Para la prueba de germinación real, se obtuvo un 84.4% (promedio) de germinación para las 5 repeticiones. Se concluye que mediante el ensayo de tetrazolio la evaluación de la viabilidad en semillas de pimentón es eficiente para las concentraciones de 1% y 0.5 %, durante 24 horas.

Se empleó ceniza volante de una central termoeléctrica, como sustituto parcial de material arcilloso, para la elaboración de cerámicos de construcción. Las probetas se realizaron con sustituciones del 5, 10, 15 y 20% (peso), mediante conformado por extrusión, se emplearon varias temperaturas de cocción (900 a 1200ºC). Esto para establecer correlaciones entre la microestructura, la topografía y las propiedades tecnológicas del cerámico tales como la resistencia mecánica a la flexión, la resistencia a la abrasión profunda, el porcentaje de absorción de agua, la conductividad térmica y la contracción lineal de secado/cocción. El análisis microestructural y de topografía dejó en evidencia que la ceniza volante es rica en fase amorfa y con presencia de elementos de carácter fundente (K y Fe). Los fenómenos de recristalización de sílice presente y el aumento de porosidad parecen explicar el comportamiento obtenido. Sustituciones hasta del 10% de CV permite obtener cerámicos con aplicabilidad en el sector de la construcción.

The objective of the research was to analyse the influence of the Lean Six Sigma management strategy on the process management of the master in mathematical education of the Universidad Francisco de Paula Santander, San José de Cúcuta, Colombia. The research follows a quantitative approach of field type correlational level. For the analysis and interpretation of the information, tools of diagramming, process mapping, descriptive and multivariate analysis, hierarchical, capacity studies, analysis of measurement systems, design of experiments, error tests and control charts were used. Once the lean six sigma philosophy is implemented, continuous improvement is observed, improvements in process capacity, 99.9% effectiveness in measurement variables, improvement in perceptions of the academic and administrative community, and process standardization, the impact of the application of Lean six sigma in a program is evaluated, demonstrating an efficient flow of its products and processes.

The excess of both private and public vehicles has hindered the mobility of large cities and, likewise, has begun to affect small cities, increasing environmental pollution, accidents, mortality, among others. The following research work includes the diagnosis and projection to the year 2021 of the traffic generated in the road corridor for future constructions in the adjacent area of the tennis club of the city of “San José de Cúcuta, Colombia”, through the collection of data by capacity of vehicles, traffic counts, surveys and vehicle registration, determining the present and future annual average daily traffic, within the main findings it was found that this sector is mostly traveled by cars, trucks and taxis. It was determined that the flow of vehicles will increase in the year 2021 by 24.62%, the constructions of shopping centers will be executed within the sector.

The design and operation of sanitary sewerage systems are based on the knowledge of peak and the average daily wastewater flows. The maximum peak factor is obtained through the ratio of the maximum flow and the average discharge flow of wastewater generated in a system. In this sense, the maximum peak factor was estimated by monitoring wastewater flow in an urban sector of the city of San José de Cúcuta, Colombia. This urban sector represents 45.6% of the sanitary sewerage of the city. Stochastic modeling of the peak flow was performed, and a mathematical model was constructed to estimate the maximum peak factor using a correlational study using statistical methodology. Through linear regression analysis, a model was obtained that estimates the value of the maximum peaking factor based on knowledge of the average daily wastewater flow. The results indicate that the model is potential, and the expression is statistically significant and satisfies the assumptions established for the classical linear regression model.
