"Diseño del manual de funciones, procesos y procedimientos para el control de inventarios de materia prima de la Sección herrajes, empresa Créditos Rodríguez".

El presente trabajo de investigación tiene como objetivo, diseñar el manual de funciones, procesos y procedimientos para el control de inventarios de materia prima de la sección de herrajes, de la empresa Créditos Rodríguez, como resultado de un diagnóstico del proceso que actualmente desarrolla la empresa con respecto al manejo del área de inventario de herrajes y una aplicación de teorías existentes que soportan el presente estudio. El diagnóstico se desarrolla a través de un diseño metodológico deductivo con un enfoque cualitativo, donde se aplican instrumentos de recolección de datos como: observación directa, cuestionarios y entrevistas, aplicados al personal involucrado en el manejo de esta área. En el resultado del diagnóstico se evidencia que la empresa no cuenta con un adecuado manejo, ni control de inventarios y presenta diversas variables de riesgo, que marcan una alta vulnerabilidad en esta área, adicional no se encuentra definido los niveles de responsabilidad y segregación de funciones, ni cuenta con información actualizada de cantidades existentes en bodega. Por lo cual se recomienda la implementación de los manuales de funciones y procedimientos diseñados, que sirva como aporte al control interno, un desarrollo de una cultura de control y supervisión en esta área, que ayude al seguimiento de actividades que se deben de realizar con el fin de actualizar las políticas y procedimientos que permitan el desarrollo de los objetivos de la empresa.PregradoCONTADOR(A) PÚBLIC

Visualization of urban floodplains in the Amazon foothill using the geo-inspired model of natural vector multi-agents (AVNG)

In the specialized literature, there are different ways to calculate and display flooded areas by geographical entities (rivers or streams), using mathematical and physical models in 1D and 2D areas; also, the use of tools such as Geographic Information Systems (GIS), the diffuse logic, the neural networks, and the genetic algorithms, among others, has been reported. This article describes the use of Geo-inspired Natural Vectors Agents (AVNG). The AVNG is founded on the agent concept, by integrating the GIS vector model to achieve the construction of an element capable of dynamically representing a geographical entity (vector) from two behaviors: the natural and the induced (Natural Agent); thus, generating an approximation to environmental management. In order to implement the AVNG conceptual model, we studied the Colombian Amazon foothills, where flash floods in urban areas cause material disasters and loss of human lives

Association rules extraction for customer segmentation in the SMEs sector using the apriori algorithm

Data Mining applied to the field of commercialization allows, among other aspects, to discover patterns of behavior in clients, which companies can use to create marketing strategies addressed to their different types of clients. This research focused on a database, the CRISP-DM methodology was applied for the Data Mining process. The database used was that corresponding to the sector of SMEs and referring to customers and sales, the analysis was made based on the PFM model (Presence, Frequency, Monetary Value), and on this model the grouping algorithms were applied: k -means, k-medoids, and SelfOrganizing Maps (SOM). To validate the result of the grouping algorithms and select the one that provides the best quality groups, the cascade evaluation technique has been used applying a classification algorithm. Finally, the Apriori algorithm was used to find associations between products for each group of customers

Importancia de la gestión de inventario en empresa de Manufacura

Inventories in an organization are of high importance whether it is an SME or a large company, having control in a sophisticated way implies having greater supervision of the stock, reducing costs and accelerating the fulfillment of demand.  Well, companies  daily have new challenges and new competences, which is why it encourages them not only to be good but also excellent, therefore, the excessive growth of competition requires companies to have a higher level of response and efficiency in its processes in order to be able to have a reception in the market in which it is moving. Planning of the expected demand must be carried out at a certain time according to the rotation of the inventory, it is important not to make mistakes such as not to consider the supplier resupply times. The problem of quantifying inventory can be as large or as small depending on the product range, over time many companies have suffered with this due to the costs and productivity it represents, having a large inventory without rotation denotes a great loss since, the stock of a company is one of the most important points that must be taken into account, because the level of stock is generally the largest investment of an organization, which can cover more than 50% of the total assets of a companydistributorLos inventarios en una organización son de alta importancia, ya sea una empresa PYME o de gran tamaño. Tener el control de una manera sofisticada, implica poseer una mayor supervisión del stock, a reducir costos y acelerar el cumplimiento de la demanda. Pues bien, las empresas diariamente tienen nuevos retos y nuevas competencias, por lo cual las impulsa a no solo ser buenas si no excelente, por ende, el crecimiento excesivo de la competencia exige a las compañías tener un mayor nivel de respuesta y de eficiencia en sus procesos para de esa manera poder tener una acogida en el mercado en el que se esté moviendo. En el presente artículo, se tiene como objetivo realizar un análisis de alguno de los métodos implementados por empresas de manufactura, con el fin de demostrar la importancia de la gestión de inventarios. Es importante no incurrir en errores tales como, no considerar los tiempos de reabastecimiento de los proveedores. La problemática de cuantificar el inventario puede ser tan grande o tan pequeño según la gama del producto, en el tiempo muchas  compañías  han sufrido con esto por los costos y la productividad que representa, el tener mucho inventario sin rotación denota una gran pérdida ya que, el stock de una empresa es uno de los puntos más importantes a tener en cuenta porque representa uno de los activos más grandes, y a su vez, supone generalmente la mayor inversión de una organización, la cual puede abarcar una cantidad superior al 50% del total de activos de una empresa distribuidora

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
