The study of the possibility of eliminating franchise in selected medical centers under insurance contract affiliated to medical sciences universities and other centers regarding service grading

Competitive atmosphere of organizations is struggling against major challenges in the present decade. Due to increasingly developments in activity environments of organizations, rapid changes in markets, and promotion of competitiveness culture, it is felt the need using the patterns which not only have the ability of evaluating the current condition of the organization, recognizing the deeply-rooted issues and organizational harms (disadvantages), and identifying improvable areas, but also building an accurate basis in order to plan strategic planning. The present study aimed to investigate the possibility of eliminating franchise in selected Medical Centers under insurance contract in Social Security, and it is done in collaboration with managers and experts of healthcare managements of Social Security of Elam, Ardabil, South Khorasan province, Khuzestan, Semnan, Kurdistan, Kohkilooyeh and Boyer Ahmad cities, and Tehran. The results indicated that, in present conditions, the elimination of franchise cannot meet the interests of insurer. Because the management method of franchise as a major and efficient tool in the field of health economy reduces indiscriminate increase of unnecessary costs, therefore its elimination is not on the benefit of Healthcare Services providers of the country

Survival Analysis: An Investigation of Covid-19 Patient Data

Ziel dieser Arbeit ist es die Realisierbarkeit einer Cox-Regression (CPH-Modell) für Covid-19 Patienten zu prüfen. Dafür wird das konstruierte Modell anhand von eingeführten Diagnostik-Methoden ausgewertet und mittels vorgestellter Erweiterungen modifiziert. Weiterhin wurde eine stichprobenartige Analyse der relevanten Literatur durchgeführt. Die Literaturanalyse hat aufgezeigt, dass die zugrundeliegenden Modell-Annahmen in lediglich 40% der untersuchten Artikel nachvollziehbar geprüft wurden. Der Neuigkeitswert dieser Arbeit begründet sich darin, dass gezeigt werden konnte, dass ein konventionelles CPHModell für den untersuchten Covid-19 Datensatz unangemessen ist. Um das CPH-Modell anwenden zu können war es notwendig die funktionale Form einer Variable anzupassen, Ausreißer zu entfernen, Zeitinteraktionsterme aufzunehmen und den Datensatz aufzuteilen. Schließlich konnte so ein finales Modell erstellt werden, welches alle Annahmen erfüllt. Allerdings erscheinen vier der geschätzten Koeffizienten fragwürdig. Daher ist die Angemessenheit des erweiterten Modells zweifelhaft. Dies impliziert, dass bei Anwendung des CPH-Modells auf Covid-19 Datensätzen die Erfüllung der Modell-Annahmen genauesten überprüft und bei Nichterfüllung robustere Schätzmethoden verwendet werden sollten. Keywords: Covid-19; Cox-Regression; CPH-Model; Proportional Hazards Model; Survival Analysis.The aim of this work is to test the feasibility of a model based on survival analysis for Covid- 19 patients. To investigate the feasibility, a Cox regression (CPH-Model) was constructed and evaluated using introduced diagnostic methods and modified using presented extensions. It is shown that disregarding the model assumptions can lead to biased estimation results. Furthermore, a sample analysis of the current literature in which CPH-Model was used revealed that the underlying model assumptions were comprehensibly tested in 40% of the articles reviewed. The novelty value of this work is based on the data analysis showing that the conventional CPH-Model is inappropriate for the Covid-19 dataset studied. In order to apply CPH-Model, the model had to be extended. It was necessary to adjust the functional form of a variable, remove outliers, include time interactions and stratify the data set. Finally, this allowed the creation of a final model that met all assumptions. However, four of the estimated coefficients appear questionable. Therefore, the adequacy of the extended model is doubtful. This implies that when CPH-Model is applied, the fulfillment of the model assumptions should be checked most carefully, and more robust estimation methods should be used in case of nonfulfillment.

Evaluación de esquemas de microfísica WRF en la simulación de una línea de turbonada sobre IRAN utilizando datos de radar y de reanálisis

Se registró una línea de turbonada en el puerto de Dayyer, al suroeste de Irán, el 19 de marzo de 2017. En el presente documento, hemos simulado los rasgos característicos asociados con la línea de turbonada mediante el modelo de investigación y pronóstico meteorológico (WRF) utilizando cinco microfísicas diferentes (MP) esquemas. Para validar las características simuladas de la línea de turbonada, la reflectividad de la sección transversal de latitud-altura y longitud-altura y el valor de precipitación derivado de la reflectividad observada recopilada por el radar meteorológico Doppler en Bushehr, datos de la estación meteorológica sinóptica en el puerto de Dayyer junto con NCEP-NCAR y ERA -Se utilizaron datos de reanálisisINTERIM. Para verificar la precipitación simulada, se calculó la curva Fractions Skill Score (FSS). El examen de los resultados de la simulación de la presión geopotencial y al nivel del mar muestra que las simulaciones del modelo que utilizan diferentes esquemas de MP concuerdan bien con los reanálisis de verificación. Además, la distribución espacial de las precipitaciones de las simulaciones y las observaciones de verificación no mostraron grandes diferencias. Sin embargo, existen diferencias significativas en los detalles de las simulaciones, como la reflectividad máxima de las celdas convectivas, la extensión vertical de las celdas de tormenta, la velocidad y dirección del viento, los valores de precipitación y las curvas FSS. Sin embargo, todas las simulaciones han mostrado celdas convectivas sobre el puerto de Dayyer en el momento de la aparición de la línea de turbonada, pero solo la simulación del modelo que usa el esquema Lin MP es consistente con la reflectividad del radar y la extensión vertical correspondientes. El gráfico FSS mostró que la habilidad cambia con la escala espacial. Los resultados utilizando el esquema de microfísica Lin cruzaron la línea FSSuniform a escalas más bajas en comparación con otros esquemas de M
