The evaluation of academic electronic bulletin boards for communication and training : HCI factors in the UK and Saudi Arabia

Electronic networks services have become essential tools for the academic community. One of the services provided has been academic electronic bulletin boards (EBBs), and the use of EBBs has increased dramatically during the last decade. One question concerns the possible application of EBBs as a means both for communication and for remote training. A series of experiments were conducted during 1991, 1992, and 1993 with the aim of examining the use of EBBs for these purposes. The first experiment was carried out to investigate whether users experience problems in using EBBs. The next extended this to see how students evaluated EBBs for communication and training purposes. The main focus of the work was BUBL. After this second experiment, modifications were made to the BUBL data and a further experiment was carried out. A different group of students looked at the modified material, and also compared it with US data using different software. The fourth experiment compared the usability of a menu-based interface (dBase III +) and a hypertext interface (HyperCard) from a student's viewpoint. It was followed by an investigation of icons to find out how well different icons could be recognised and the possibility of using them for language-independent instructions. Finally, the characteristics and problems of GULFNET users were examined. The evaluation has demonstrated the general acceptability of EBBs and their likely value for training purposes. This leads to a discussion of how an EBB might best be developed for use in communication and training on GULFNET

Study on Pre-Occupancy Purging of Air for a Low Occupancy Office in a Tropical Country

AbstractPreoccupancy purging of air-conditioned rooms is practiced in buildings in order to remove air contaminants so that acceptable indoor air quality can exist at the start of occupancy, in accordance to standards such as ASHRAE Standard 62-2001. During a typical daily exercise, the fresh intake and exhaust air dampers are fully opened to allow adequate ventilation with the outdoors. In the present work the effectiveness of preoccupancy purging in an office building of a university in a tropical climate is studied. Observations of indoor CO2 levels, relative humidity and temperature around the time of preoccupancy purging are made. The duration of purging is varied so as to assess the optimum period. Preliminary results indicate that that preoccupancy purging may not be required for the building of study. It is also found that the current practice of preoccupancy purging promotes the growth of mold

Cost-Effectiveness of Clinical Pharmacy Education on Infection Management among Patients with Chronic Kidney Disease in an Indonesian Hospital

AbstractObjectivesThis study evaluated the clinical and economic impacts of clinical pharmacy education (CPE) on infection management among patients with chronic kidney disease (CKD) stages 4 and 5 in Haji Adam Malik Hospital, Indonesia.MethodsA quasi-experimental economic evaluation comparing CPE impact on 6-month CKD mortality was conducted on the basis of payer perspective. The experimental group (n = 63) received care by health care providers who were given CPE on drug-related problems and dose adjustment. The control group (n = 80) was based on the historical cohort of patients who received care before the CPE. Measure of clinical outcome applied in this study was number of lives saved/100 patients treated. Cost-effectiveness ratios for CKD stages 4 and 5 patients without CPE and with CPE and incremental cost-effectiveness ratios (ICERs) for CKD stages 4 and 5 patients were analyzed.ResultsLives saved (%) in the treatment of CKD without CPE: CKD stage 4, 78.57; CKD stage 5, 57.58. Lives saved (%) in the treatment of CKD with CPE: CKD stage 4, 88.89; CKD stage 5, 65.45. Cost-effectiveness ratios for stage 4 with and without CPEs were Rp3,348,733.27 and Rp3,519,931.009, respectively. Cost-effectiveness ratios for stage 5 with and without CPEs were Rp7,137,874.93 and Rp7,871,822.27, respectively. ICERs were Rp2,045,341.22 for CKD stage 4 and Rp1,767,585.60 for CKD stage 5.ConclusionsTreatment of CKD stages 4 and 5 with CPE was more effective and cost-effective compared with treatment of CKD stages 4 and 5 without CPE. The ICERs indicated that extra costs were required to increase life saved in both stages

The effect of rutin on lipid profile and liver function enzymes on alloxan induced hyperglycaemic wistar rats

The aim of this research was to investigate the effects of rutin on lipid profile and liver function enzymes on alloxan induced hyperglycaemia in Wistar rats. Hyperglycaemic was induced by intraperitoneal injection of 150 mg/kg alloxan monohydrate. The rats were grouped into five groups of five rats each. Group 1 served as the diabetic negative control, Group 2 served as positive control and was treated with 2 mg/kg glibenclamide, while Groups 3, 4 and 5 were treated with 50, 100 and 200 mg/kg body weight of rutin respectively. Rutin was administered to the animals orally for a period of four weeks. At the end of the experimental period, the rats from each experimental group were sacrificed using light chloroform and sera were collected for the determination of lipid profile and liver function enzymes. There was a significant (p<0.05) decreased in the total cholesterol, triglyceride and low density lipoprotein as compared to control. However, there was a significant (p<0.05) increased in the level of high density lipoprotein when compared to diabetic control. Furthermore, there was a significant (p<0.05) decreased in the serum liver enzymes; Aspartate transaminase (AST) Alanine transaminase (ALT) and Alkaline phosphates (ALP) as compared to control. As regards to the reference drug 2mg/kg glibenclamide there was a significant (p<0.05) increased in the liver enzymes function as compared to control. Conclusion, rutin has hypolipidemic effect and also decreased liver function enzymes activity on alloxan induced hyperglycaemic rats.Keywords: Rutin, Hyperglycaemia, Alloxan, Lipid profile, Liver enzyme

Denture marking: a mandatory procedure to aid forensic identification

Purpose - The purpose of this paper is to highlight the significance of placing identification marks on dentures. Design/methodology/approach - This paper reviews the legislation with regard to denture marking in certain countries, various methods of denture marking and describes a simple, inexpensive, paper-based labelling system. Findings - Various methods have been proposed for denture marking but it is important to use a method that is simple, practical, affordable and universally acceptable. Practical implications - The identification of unknown or missing persons by means of denture marking is a very successful method of identification in forensic investigation. It is also useful for patients residing in hospitals and community homes where dentures could be misplaced, particularly during cleaning by personnel where there is a chance of loss or mix-up. The importance of denture marking should be emphasized by all law-enforcing authorities and should be promoted among all dentists, towards making it a compulsory routine dental procedure throughout the world. Originality/value - In Malaysia, denture marking, as recommended by its Ministry of Health, uses a unique coding system which can readily provide information about the wearer in whichever part of the world the person is found. The method applied is simple, practical and affordable and can easily be adapted by others. It can be of great value during times of crisis
