Progettazione e sviluppo di un sistema software per la gestione del call e del ticket system del processo customer care

Lo scopo del lavoro di questa tesi è la progettazione e lo sviluppo di un sistema software ad-hoc per la gestione del sistema (inbound) di chiamate e di ticketing del processo di customer care di un’azienda, rendendo così più efficaci ed efficienti le risposte alle richieste di assistenza da parte di un cliente e consentendo un migliore utilizzo delle risorse aziendali. Gli obiettivi del software sono: - permettere l’utilizzo del sistema ai diversi operatori dislocati nelle diverse nazioni del modo; - fornire a tali operatori funzionalità aggiuntive rispetto al sistema precedente; - generare report automatici, in relazione al periodo di riferimento scelto, permettendo una più corretta analisi dei dati. Tale sistema software verrà integrato nel sistema back-end di amministrazione e gestione dell’azienda AvMap Satellite Navigation . L’attività di tesi è iniziato dopo uno stage svolto all’interno dell’azienda. Questo elaborato ha lo scopo di illustrare la progettazione e lo sviluppo del sistema ReQuest Support (RQS), per la gestione integrata delle chiamate (e-mail, telefonate in ingresso) e la generazione di report automatici e personalizzati di un azienda. Parte integrate del lavoro è la progettazione di un database che raccolga informazioni derivanti da fonti diverse e consenta di risolvere le interrogazioni più frequenti in modo ottimizzato

High Compression Pressure over the Calf is More Effective than Graduated Compression in Enhancing Venous Pump Function

AbstractBackgroundGraduated compression is routinely employed as standard therapy for chronic venous insufficiency.AimThe study aims to compare the haemodynamic efficiency of a multi-component graduated compression bandage (GCB) versus a negative graduated compression bandage (NGCB) applied with higher pressure over the calf.MethodsIn 20 patients, all affected by greater saphenous vein (GSV) incompetence and candidates for surgery (Clinical, etiologic, anatomic and pathophysiologic data, CEAP C2-C5), the ejection fraction of the venous calf pump was measured using a plethysmographic method during a standardised walking test without compression, with GCB and NGCB, all composed of the same short-stretch material. Sub-bandage pressures were measured simultaneously over the distal leg and over the calf.ResultsNGCBs with median pressures higher at the calf (62 mmHg) than at the distal leg (50 mmHg) achieved a significantly higher increase of ejection fraction (median +157%) compared with GCB, (+115%) with a distal pressure of 54 mmHg and a calf pressure of 28 mmHg (P < 0.001).ConclusionsPatients with severe venous incompetence have a greater haemodynamic benefit from NGCB, especially during standing and walking, than from GCB

Compression Stockings with a Negative Pressure Gradient Have a More Pronounced Effect on Venous Pumping Function than Graduated Elastic Compression Stockings

AbstractObjectivesTo measure the effect on the venous pumping function of a stocking providing a negative pressure gradient with higher pressures over the calf in comparison to a conventional graduated elastic compression stocking (GECS) in patients with advanced venous insufficiency.DesignExperimental study.Material30 patients with severe superficial chronic venous insufficiency were enrolled. Two elastic stocking designs exerting a pressure at ankle between 15 and 25 mm Hg were compared; a conventional GECS and a stocking exerting a higher pressure over the calf than over the ankle producing a “progressive” increase in compression (PECS).Methodthe venous calf pumping function was assessed by measuring the ejection fraction (EF) from the lower leg by a plethysmographic method during a standardised exercise. Interface pressure of the 2 compression devices was simultaneously recorded both at B1 = 12 cm above ankle, C = just above widest part of calf.ResultsThe mean increase of EF produced by PECS was +75% (95 CI 48,7-101,3) compared with +32% (95%CI 16,8-48,6) with GECS (P < 0.001). There was a significant correlation between EF and the stocking pressure measured at calf level during standing and walking.ConclusionStockings exerting a higher pressure on the calf than on the ankle show a greater efficacy in increasing the venous ejection fraction from the leg
