Diseño e implementación de software guía para el modelado de dinámica de sistemas

83 p.Los sistemas de información proveen de información vital a las organizaciones y suponen un gran apoyo a sus operaciones. En el ámbito de la dinámica de sistemas, el profesor Martin Schaffernicht ha trabajado hace años en mejorar la enseñanza de dicha disciplina a pesar de los contratiempos que supusieron la pandemia, la educación en línea y las limitaciones de una guía en formato Word. En un ánimo de continuar innovando en su propuesta docente, el profesor Schaffernicht plantea la idea de implementar un sistema de información, en forma de plataforma web, que sirva como guía para el aprendizaje del modelado conceptual de dinámica de sistema. El objetivo de esta plataforma es solventar las brechas que ha detectado en las versiones anteriores de su guía de modelado conceptual. Esto es, a través de una interfaz amigable con los alumnos, que ofrezca una experiencia intuitiva para obtener los conocimientos del curso. Al mismo tiempo, se busca obtener retroalimentación de los avances de los alumnos, lo que le permite tanto a ellos como a los profesores del módulo conocer cómo progresan en los aprendizajes. Este proyecto se centra en el desarrollo de la plataforma web antes mencionada, así como en el modo en el que se abordan los desafíos que conllevan la adaptación de los contenidos de la guía de modelado conceptual a un formato de web interactiva, apoyándolo desde el punto de vista de la experiencia de usuario (UX) y la gamificación. // ABSTRACT: Information systems provide vital information to organizations and support their operations. In the field of system dynamics, Professor Martin Schaffernicht has been working for years to improve the teaching of this discipline despite the setbacks of the pandemic, online education, and the limitations of a Word guide. In an effort to continue innovating his teaching proposals, Professor Schaffernicht suggests the idea of implementing an information system, in the form of a web platform, to serve as a guide for learning the conceptual modeling of system dynamics. The objective of this platform is to overcome the gaps that have been detected in previous versions of its conceptual modeling guide. That is, through a student-friendly interface that offers an intuitive experience to obtain the knowledge of the course. At the same time, it seeks to obtain feedback on the progress of the students, which allows them as well as the teachers of the module to know how they are progressing in their learning. This project focuses on the development of the previously mentioned web platform, as well as the way in which the challenges involved in adapting the contents of the conceptual modeling guide to an interactive web format are addressed, supporting it from a user experience (UX) and gamification point of view

Análisis de los factores de riesgo de la hipertensión arterial en Colima, México Analysis of risk factors for hypertension in Colima, Mexico

OBJETIVO: Evaluar la posible asociación de la edad, el sexo, el sobrepeso, los antecedentes familiares de hipertensión arterial (HTA), el alcoholismo y el sedentarismo con la HTA en la población adulta de la ciudad de Colima, México. MÉTODOS: Estudio transversal analítico de base poblacional. Se aplicó una encuesta estructurada a 280 adultos mayores de 30 años que residían en la ciudad mexicana de Colima en 2001 y 2002. Las variables estudiadas fueron el sexo, la edad, el peso, la talla, los antecedentes familiares de HTA, la práctica de ejercicio físico, el tabaquismo y el consumo de alcohol. La presión arterial (PA) se midió por el método auscultatorio. Las mediciones limítrofes o dudosas se repitieron cuatro o cinco días después. Se consideró que había HTA cuando la PA sistólica era >140 mm Hg y la presión arterial diastólica era > 90 mm Hg, o la persona estaba bajo tratamiento antihipertensivo. Se calcularon las razones de posibilidades (odds ratios, RP) de las variables estudiadas y sus intervalos de confianza de 95% (IC95%). La asociación entre las variables y la HTA se estimó mediante regresión logística y la interacción mediante el coeficiente de productos de interacción. RESULTADOS: La prevalencia bruta de HTA fue de 28,6%. La prevalencia fue mayor en hombres que en mujeres (42,1% frente a 19,2%, respectivamente; RP = 3,04; IC95%: 1,8 a 5,2) y en personas mayores de 49 años que en personas de 30 a 49 años (36,8% frente a 21,9%, respectivamente; RP = 2,07; IC95%: 1,22 a 3,50). Los antecedentes familiares de HTA y el sobrepeso mostraron asociación con la HTA, mientras que la práctica de ejercicio físico tuvo un efecto protector (RP = 0,45; 0,23 a 0,86). Se encontró interacción entre la HTA y la edad (> 50 años), los antecedentes familiares de HTA, el sobrepeso y la práctica de ejercicio físico, particularmente en mujeres. CONCLUSIONES: La prevalencia de HTA en Colima es muy semejante a la encontrada a nivel nacional en México. Su fuerte asociación con el sexo masculino, independientemente de las otras variables, resalta la necesidad de promover campañas preventivas más enfocadas en los hombres.OBJECTIVE: To evaluate the possible association that age, sex, excess weight, family history of hypertension, alcoholism, and sedentary lifestyle have with hypertension in the adult population of the city of Colima, Mexico. METHODS: This was a population-based analytic cross-sectional study. A structured survey was used with 280 adults older than 30 years of age who were living in the city of Colima in 2001 and 2002. The variables studied were sex, age, weight, height, family history of hypertension, engaging in physical exercise, smoking, and consuming alcohol. Blood pressure (BP) was measured with the auscultatory method. Borderline or doubtful measurements were checked again four or five days later. Hypertension was defined as systolic BP > 140 mm Hg and diastolic blood pressure > 90 mm Hg, or as the person being under antihypertensive treatment. The odds ratios (ORs) of the variables studied were calculated, along with their 95% confidence intervals (95% CIs). The association between the variables and hypertension was estimated through logistic regression, and their interaction through the coefficient of the interaction products. RESULTS: The overall prevalence of hypertension was 28.6%. The prevalence was higher in men than in women (42.1% vs. 19.2%; OR = 3.04, 95% CI: 1.8 to 5.2) and in people older than 49 years than in people 30 to 49 years old (36.8% vs. 21.9%; OR = 2.07, 95% CI: 1.22 to 3.50). A family history of hypertension and excess weight were associated with hypertension, while physical exercise had a protective effect (OR = 0.45; 95% CI: 0.23 to 0.86). There was interaction between hypertension and age > 50 years, a family history of hypertension, overweight, and physical exercise, especially among women. CONCLUSIONS: The prevalence of hypertension in Colima is very similar to that for Mexico as a whole. The strong association that hypertension had with male gender, regardless of the other variables, emphasizes the need for promoting prevention campaigns that focus more on men

Evaluation of the novel antichagasic activity of [1,2,3]triazolo[1,5-a]triazolo[1,5-apyridine derivatives

© 2017 Bentham Science Publishers. Trypanosoma cruzi is the causative agent of Chagas disease. This parasite is vulnerable to the effects of ROS as its main defense mechanism against exogenous agents trypanothione is also another weakness of the parasite that investigated related to the inhibition of enzymes belonging P450 system, mainly CYP51. In our group we have synthesized a series of triazoles known as [1,2,3]triazolo[1,5-a]pyridyl ketones, and pyridyl ketones. These families have shown interesting structural features due to the presence of electron withdrawing moieties attached to the main heterocycle (triazoles and/or pyridines) and are proposed as potential target in the parasite, by the presence of the carbonyl group being able to be reduced and form a free radical that could interact with molecular oxygen generating ROS in the parasite. Furthermore, the triazole ring and pyridines have been considered as potent inhibitors of sterol biosynthesis, the lock being part CYP51. Ou

Three-dimensional analysis of the physiological foramen geometry of maxillary and mandibular molars by means of micro-CT

The aim of this study was to investigate the physiological foramen diameter, shape and distance between physiological and anatomical apex of maxillary and mandibular first and second molars. Accurate knowledge of the physiological foramina morphology; thus, inherent mechanical shaping technical hindrances, is decisive when taking the corresponding root canal final preparation decision. The morphological dimensions of a total of 1727 physiological foramina were investigated by means of micro-computed tomography. Mean narrow and wide (to a high number, oval) diameters of the physiological foramen were 0.24, 0.22 and 0.33 mm and 0.33, 0.31 and 0.42 mm in mesiobuccal (MB), distobuccal (DB) and palatal (P) roots in maxillary first molars; 0.24, 0.22 and 0.33 mm and 0.41, 0.33 and 0.44 in MB, DB, and P roots in maxillary second molars. Mandibular first molars showed mean narrow and wide diameters of 0.24 and 0.30 mm and of 0.39 and 0.46 mm in mesial (M) and distal (D) roots; second mandibular molars showed 0.25 and 0.31 mm and 0.47 mm in M and D roots. The mean distance between the physiological foramina and anatomical apex was 0.82, 0.81 and 1.02 mm and 0.54, 0.43 and 0.63 mm in MB, DB and P roots of the maxillary first and second molars, respectively. A mean distance of 0.95 mm (M) and 1.05 mm (D) in the first and 0.78 mm (M) and 0.81 mm (D) in the second mandibular molars was observed. Based on the results obtained, assumable recommendations for final preparation size of the physiological foramen were calculated. However, when taking into consideration, the resulting standard deviations of marginal errors must be cautiously considered when taking a final decision in clinical endodontic treatment
