Propuesta de sistema de gestión del servicio de control de tránsito aéreo de aeronaves de carga internacional del aeropuerto Jorge Chavez Lima 2024
Este trabajo de suficiencia profesional se centra en mejorar el control de tránsito aéreo para la carga internacional en el Aeropuerto Jorge Chávez de Lima, que está bajo la gestión de la Empresa Estatal de Servicios de Navegación Aérea. La ineficiencia del servicio de control de tráfico aéreo, que afecta la competitividad del aeropuerto, es el principal problema. El enfoque cualitativo del estudio incluye entrevistas con expertos de la empresa, análisis de literatura y revisión de datos operativos. Ante ello, se presentan tres propuestas de solución: una torre de control remoto, el Sistema de Información Operativa (OIS) de CADENA y el Sistema de Información de Gestión de Datos Aéreos Globales (GADM) de IATA. El análisis comparativo señala que el OIS de CADENA es la mejor opción porque puede mejorar la coordinación y la eficiencia en la gestión del tráfico aéreo Internacional al compartir datos en tiempo real. Esta solución es económica e inmediata. El objetivo de implementar OIS es mejorar las operaciones de carga aérea y mejorar la posición competitiva de la empresa. La conclusión del estudio es que se debe avanzar con OIS para mejorar la eficiencia operativa del Aeropuerto Jorge Chávez, el cual registró un movimiento de 211,288 toneladas en volumen de carga aérea a nivel internacional.This professional sufficiency work focuses on improving air traffic control for international cargo at Jorge Chávez Airport in Lima, which is under the management of the State-Owned Air Navigation Services Company. The inefficiency of the air traffic control service, which affects the airport's competitiveness, is the main problem. The qualitative approach of the study includes interviews with company's experts, literature analysis and review of operational data. Three proposed solutions are presented: a remote-control tower, CADENA's Operational Information System (OIS) and IATA's Global Air Data Management Information System (GADM). The comparative analysis indicates that CADENA's OIS is the best option because it can improve coordination and efficiency in international air traffic management by sharing data in real time. This solution is cost-effective and immediate. The objective of implementing OIS is to improve air cargo operations and enhance company's competitive position. The conclusion of the study is to move forward with OIS to improve the operational efficiency of Jorge Chavez Airport, which recorded a movement of 211,288 tons in international air cargo volume.Trabajo de Suficiencia ProfesionalODS 9: Industria, Innovación e InfraestructuraODS 11: Ciudades y Comunidades SosteniblesODS 8: Trabajo Decente y Crecimiento Económic
Aislamiento e identificación de bacterias proteolíticas, amilolíticas, lipolíticas y quitinolíticas de residuos de langostinos
Bacteria and microbial enzymes are biocatalysts and can be used as an alternative to industrial chemical processes. The present study focused on isolating and identifying bacterial strains from shrimp waste, that produce amylases, lipases, proteases and chitinases with potential use on shrimp waste treatment. Thirty-two bacterial strains were isolated, phenotypically characterized, and identified by the API system and the molecular analysis of the 16S rDNA. It was found that 28.13% of the isolated bacterial strains had amylolytic capacity, 87.50% lipolytic, 96.88% proteolytic and 28.13% chitinolytic capacity on agar plates with specific substrates. The genera Bacillus, Burkholderia, Ochrobactrum, Vibrio, Pseudomonas and Shewanella were identified. Bacteria with enzymatic capacities isolated in the present study, could be used to obtain by-products from shrimp waste as well as other industrial applications.Las bacterias y enzimas microbianas son biocatalizadores y pueden ser usadas como alternativa en los procesos químicos industriales. El presente estudio se centró en aislar e identificar cepas bacterianas a partir de desechos de langostinos, capaces de producir amilasas, lipasas, proteasas y quitinasas, que tuvieran potencial aplicación en el tratamiento de residuos de langostinos. Se aisló treinta y dos cepas bacterianas, caracterizadas fenotípicamente e identificadas mediante el sistema API 20 y mediante análisis molecular basado en el ADNr 16S. Se encontró que el 28.13% de las cepas bacterianas aisladas tenían capacidad amilolítica, 87.50% lipolítica, 96.88% proteolítica y 28.13% capacidad quitinolítica en placas de agar con sustratos específicos. Los géneros identificados fueron Bacillus, Burkholderia, Ochrobactrum, Vibrio, Pseudomonas y Shewanella. Las bacterias con capacidades enzimáticas aisladas en el presente estudio, podrían ser usadas para obtener subproductos de los desechos de langostinos, así como en otras aplicaciones industriales
Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries
Background
Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks.
Methods
The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned.
Results
A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31).
Conclusion
Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
