A study was conducted to ascertain the efficiency and effectiveness of an air filtration system (Electromedia Model 100C, Clean Air UK, UK) in the hospital ward. The sampling was conducted using a portable Surface Air Sampler (Cherwell Laboratories, Bicester, UK) in conjunction with settle plates. Samples were taken two days before and two days following activation of the filtration system and results compared. A clear, demonstrable, statistically significant reduction in microbial organisms following the activation of the filtration systems is evident (81% settle plates; 24% Surface Air Sampler). This study has implications for the improved health and welfare of patients and healthcare workers who may benefit through the implementation of such a system.

This study examined the role that dissimilar bare footprint collection and measurement processes have on the Reel method of measurement in forensic podiatry and its use in the Criminal Justice System. Previous research indicated the Reel method was a valid and reliable measurement system for bare footprint analysis but various collection systems had been used to collect footprint data and both manual and digital measurement processes were utilized in forensic podiatry and other disciplines. This study contributes to the debate about collecting bare footprints; the techniques employed to quantify various Reel measurements and considered whether there was asymmetry between footprints of the same person. An inductive, quantitative paradigm used two gathering procedures for footprint collection and the subsequent dynamic footprints subjected to Adobe© Photoshop© measurement of a truncated version of the Reel variables. The findings from the research suggested there were no statically significant differences in the footprint measurements using dissimilar collection devices, that Adobe© Photoshop© technique for measurement offers a reasonably easy method for measurements and offers alternative findings to that of Reel using a comparative digital measuring arrangement. Standard Error of Mean showed variation between feet/footprints and between collection systems and the findings provide support for the Reel study.
