What Kind of Information and Communication Technologies Do Patients with Type 2 Diabetes Mellitus Prefer? An Ecuadorian Cross-Sectional Study.

PURPOSE: The purpose of this study is to assess the frequency of use of information and communication technologies and patterns of preference among Ecuadorian patients with diabetes. METHODS: We conducted an anonymous cross-sectional survey on type 2 diabetes mellitus. A chi-square test for association and adjusted regression analyses were performed. RESULTS: 248 patients were enrolled, with a mean sample age of 57.7 years. SMS was the most used ICT (66.0%). The Internet was used by 45.2% of patients to obtain information about diabetes. SMS and email were rated as the most useful ICTs for receiving information (64.5% and 28.1%, resp.) and asking physicians about diabetes (63.8% and 26.1%, resp.). Patients were also interested in receiving disease information (82.4%) and asking physicians about diabetes (84.7%) through WhatsApp. Adjusted logistic regressions revealed that individuals aged 55 years or younger, those with superior degree level, and those with long diabetes history preferred email for receiving information and asking physicians about diabetes compared to those above 55 years, those with low education level, and those with short diabetes history, respectively. CONCLUSION: Understanding preferences of ICTs among patients with diabetes could facilitate application development targeted towards specific requirements from patients.

Balance energetico del sistema de refrigeracion por amoniaco Cerveceria Boliviana Nacional S.A. Planta La Paz

El presente proyecto consta de cinco capitulos, se realiza una introduccion general, relacionado al incremento de la demanda de frio, en los centros de almacenamiento de producto de la Cerveceria Boliviana Nacional S.A.(Planta La Paz), la misma que la implica la necesidad de utilizar en mayor escala los componentes de la cadena de frio.Como objetivos, el proyecto pretende dar respuesta a la situacion actual y futura del consumo de frio mediante un marco teorico y practico.Asimismo evaluaremos los componentes de la cadena de frio y ofrecer alternativas para la disminucion de su consumo en sus diferentes puntos. Se da una base introductoria teorica, que trata acerca de los principios fundamentales de la fisica y termodinamica, que son esenciales para comprender el estudio de refrigeracion por compresion mecanica.Asimismo, se hace hincapie en la elaboracion del diagrama del ciclo de refrigeracion industrial por bombeo (presion-entalpia), el cual responde al ciclo de refrigeracion de la empresa.
