Capacity planning is a critical task in network management. It identifies how much capacity is needed to match future traffic demand. It directly affects customer satisfaction and revenues. In this work we present a network usage analysis tool called Dynamic Netvalue Analyzer (DNA), which helps alleviate a big problem that network engineers and marketing executives face– making optimal resource...

The role of finger usage upon learning arithmetic has received increasing interest from various disciplines. In this opinion paper, we would like to emphasize that finger usage in calculation is not a unitary phenomenon. Rather, we propose two different types of finger usage: First, in many countries and independent of the number system in use, typically developing children use fingers as impor...

Every approach to interaction design reflects an implicit metaphor held by designers of relationships between the system and user. In the case of interactive research prototypes, as found in ubiquitous computing applications, these implicit metaphors can be inappropriate to real usage scenarios. We propose a novel metaphor of tangible interfaces as being a solid diagram to which we can apply ab...

It has been demonstrated that the use of suitable metaphors in the user service interface can have a dramatic effect on the way in which the user perceives the services, depending on the category of metaphor chosen. An earlier paper by the authors postulated that interactional metaphors might lead to greater long term usage of services, as they direct the user to thinking about what the service...

INTRODUCTION Antibiotic resistance is a rapidly emerging problem. A major concern is methicillin-resistant Staphylococcus aureus (MRSA), especially in developing countries where cost-effectiveness is imperative. Restriction of vancomycin usage is necessary to reduce the emergence of vancomycin-resistant organisms. The aim of this study was to look into the appropriate use of vancomycin based on...

INTRODUCTION The resistance to antibacterial drugs is an emerging worldwide problem. Numbers of inappropriate ways to use antibiotics contribute to this issue. Self-medication is one of them. This study seeks to find out how prevalent the self-medication with antibiotics, their storage at home and the inappropriate acquisition of antibacterial drugs are among medical specialists in Vilnius, Lit...

OBJECTIVES The aim of this study was to evaluate the appropriateness of piperacillin/tazobactam (Tazocin(®); Pfizer, New York, NY) usage in our hospital. SUBJECTS AND METHODS This retrospective study was designed to involve all patients admitted to Hamad General Hospital and prescribed piperacillin/tazobactam as an empiric therapy from January 1 to March 31, 2008. The medical records of such ...

ICD shocks can result from a variety of etiologies; determining the proper etiology of the inappropriate shock is essential for correction of the problem. Electromagnetic interference (EMI) can mimic cardiac signals and cause inappropriate defibrillator shocks. We present two cases of inappropriate ICD shocks due to EMI and reversal of the proximal and distal DF-1 lead terminals of the ICD lead...

Although DeLone, McLean and others insist that system usage is a key variable in information systems research, the system usage construct has received little theoretical scrutiny, boasts no widely accepted definition, and has been operationalized by a diverse set of unsystematized measures. In this article, we present a systematic approach for reconceptualizing the system usage construct in par...
