“…Table 6 illustrates that for the first task, the Receptionist will have to be observed 5 times on day 1; 6 times on day 2; 9 times on day 3; 8 times on day 4; 6 times on day 5; 10 times on day 6; 7 times on day 7; and 7 times on day 8. Summary of the Results: According to the summary of the pilot study for each worker, a number of idle times were discovered and less productivity was measured which identified factors of non productivity at the Tourism Company [8]. Table 7 shows the summary of pilot study for three workers.…”

This paper discusses the application of activity sampling in work and performance analysis in a tourist services company. Abnormal job delays were observed based on mainly employee observation studies at the tourist company in South Africa. A detailed account of the data collected is presented, assessed and analysed for three departments, the administration department, marketing department and the reception. The importance of activity sampling in organizations was demonstrated by its use in identifying idle and ineffective time in these departments. A large number of observations were made over a period of time to afford the results and findings the necessary statistical significance. Observations enabled recording of what was happening at given instances to determine activities undertaken and to capture delays. The study shows the importance of activity sampling in diagnosing problems and supporting decision making and taking in a service organisation.

“…Various techniques were proposed to overcome the shortcomings of standard clinical routines. These recent techniques include laser Doppler flowmetry [1], laser speckle contrast imaging [12], photoacoustic imaging [13], and enhanced image processing algorithms [14], all of which were reported able to measure cutaneous blood flow and tissue perfusion. This is to identify the effectiveness of the standard medical treatment towards diabetic wound healing rate with minimal evaluation time, and hence reducing the feeling of anxiety amongst the affected patients.…”

This paper aims to demonstrate the feasibility of using a low cost laser speckle imaging built for the detection of changes of tissue blood flow with different experimental conditions. Images of anterior portion of the wrist of four healthy adult volunteers illuminated by a laser source of wavelength 650 nm were collected via a monochromatic charge-coupled device (CCD) imager. The mean and standard deviation (SD) of blood flow perfusion was predicted as 3.92 ± 1.47 and 2.90 ± 1.39, respectively, for measurements at rest condition and during blood flow occlusion. This work showed the ability of the developed system to detect changes in blood flow perfusion with differences in the experimental conditions. However, further works are required to further confirm the suitability of the system before it is used for different clinical applications such as monitoring of blood flow during diabetic foot ulcers healing following standard medical treatment.
