Modeling the prediction of business intelligence system effectiveness.

Although business intelligence (BI) technologies are continually evolving, the capability to apply BI technologies has become an indispensable resource for enterprises running in today's complex, uncertain and dynamic business environment. This study performed pioneering work by constructing models and rules for the prediction of business intelligence system effectiveness (BISE) in relation to the implementation of BI solutions. For enterprises, effectively managing critical attributes that determine BISE to develop prediction models with a set of rules for self-evaluation of the effectiveness of BI solutions is necessary to improve BI implementation and ensure its success. The main study findings identified the critical prediction indicators of BISE that are important to forecasting BI performance and highlighted five classification and prediction rules of BISE derived from decision tree structures, as well as a refined regression prediction model with four critical prediction indicators constructed by logistic regression analysis that can enable enterprises to improve BISE while effectively managing BI solution implementation and catering to academics to whom theory is important.

Community-acquired Pseudomonas aeruginosa pneumonia complicated with loculated empyema in an infant with selective IgA deficiency.

Pseudomonas aeruginosa is widely prevalent in the hospital environment, especially in intensive care units. Selective IgA deficiency is characterized by a serum IgA level less than 5 mg/dl with no deficiency of other immunoglobulins. The occurrence of community-acquired P. aeruginosa pneumonia with empyema is rare in pediatric patients. We present a 10-month-old male infant who was referred due to persistent fever and progressive respiratory distress for 1 week. A chest radiograph revealed a right lobar pneumonia with pleural effusion. P. aeruginosa that was subsequently isolated from both blood and pleural effusion cultures. The patient received treatment with ceftazidime and intrapleural instillation of urokinase to promote drainage of empyema. Subsequent immunological screening revealed a very low serum IgA level (<5 mg/dl). We present our experience in successfully treating a loculated empyema with intrapleural instillation of urokinase in an infant. It is also important for pediatricians to be aware that they should be alert for the patient who present with respiratory infections due to unusual organisms. An advanced immunological study to investigate the underlying disorders in these patients is mandatory.
