OBJECTIVE: This study aimed to examine the relationship between specific physical and psychosocial factors and/or ergonomic conditions on MSD symptoms among dentists in Malaysia.
METHODS: A group of 85 dentists was asked to complete a questionnaire to determine whether their complaints were related to physical and psychosocial factors and/or ergonomic conditions in their practices.
RESULTS: Among the nine reviewed body areas, the shoulders were most often affected by symptoms of MSDs (92.7%). Moreover, MSDs of the neck and upper back were most likely to prevent these practitioners from engaging in normal activities (32.9%). In general, no significant differences were found in the prevalence of MSD symptoms in relation to gender, age, body mass index, years in practice, number of patients, and frequency of breaks.
CONCLUSIONS: Our results were consistent with those reported in other studies that focused on MSD problems among dentists in other countries. To reduce the prevalence of MSDs, more attention should be paid to instituting ergonomically sensible approaches in the dental practice setting.
OBJECTIVE: The broad objective of this study was to investigate the direct and indirect effects of behavioral factors on the psychological and physiological health of workers.
METHODS: The latest, second generation technique, which is structural equation modeling, is used to identify the relationships between behavioral antecedents and health outcomes. A total of 277 technical workers participated, aged between 20 and 49 and were healthy in all aspects.
RESULTS: The study results showed quantitative demands, emotional demands, work-family conflict, and job insecurity were significantly associated with both psychological (stress) and physiological (Body Mass Index) factors. The social support of colleagues produced mixed findings with direct and indirect paths. Stress also significantly mediates the psychosocial factors and burnout of the workers.
CONCLUSION: The study concluded that workers were physically available, but they experienced distractions as members of social systems, affecting their physiological and psychological health.
OBJECTIVE: To evaluate the psychometrics properties of the Malay version of M-JCQ among nurses in Malaysia.
METHODS: This cross-sectional study was carried out on nurses working in 4 public hospitals in Klang Valley area, Malaysia. M-JCQ was used to assess the perceived psychosocial stressors and physical demands of nurses at their workplaces. Construct validity of the questionnaire was examined using exploratory factor analysis (EFA). Cronbach's α values were used to estimate the reliability (internal consistency) of the M-JCQ.
RESULTS: EFA showed that 34 selected items were loaded in 4 factors. Except for psychological job demand (Cronbach's α 0.51), the remaining 3 α values for 3 subscales (job control, social support, and physical demand) were greater than 0.70, indicating acceptable internal consistency. However, an item was excluded due to poor item-total correlation (r<0.3). The final M-JCQ was consisted of 33 items.
CONCLUSION: The M-JCQ is a reliable and valid instrument to measure psychosocial and physical stressors in the workplace of public hospital nurses in Malaysia.
Methods: A descriptive cross-sectional study was carried out at the Kubang Kerian Nursing College, Kelantan which involved 346 respondents using simple random sampling method. The inclusion criteria were year one, two and three of nursing students who have clinical posting and voluntarily joining the study. Perceived Stress Scale (PSS) and Brief COPE inventory were utilised in the data collection. Higher mean score indicates higher degree of stress.
Results: Clinical assignments and workload were the main stressor (mean = 3.19, SD = 1.09). Religion approach was the most coping strategy applied (mean = 3.30, SD = 0.71). Pearson's correlation coefficient test found that six domains of stressors during clinical practices (taking care of patients; clinical educators/instructors and ward staff; clinical assignments and workload; peers and nursing students from other college; lack of professional knowledge and skills and clinical environment) were statistically significant correlation with coping strategies, where P-value < 0.05.
Conclusion: Clinical assignment was the main stressor among nursing students; therefore, successful activities should be promoted to help them in managing clinical assignment and enhancing knowledge in religion.
PURPOSE: The purpose of this simulation study was to establish a reference percentage value that can be used to effectively reduce the size and polygons of the 3D mesh without drastically affecting the dimensions of the prosthesis itself.
MATERIAL AND METHODS: Fifteen different maxillary palatal defects were simulated on a dental cast and scanned to create 3D casts. Digital bulbs were fabricated from the casts. Conventional bulbs for the defects were fabricated, scanned, and compared with the digital bulb to serve as a control. The polygon parameters of digital bulbs were then reduced by different percentages (75%, 50%, 25%, 10%, 5%, and 1% of the original mesh) which created a total of 105 meshes across 7 mesh groups. The reduced mesh files were compared individually with the original design in an open-source point cloud comparison software program. The parameters of comparison used in this study were Hausdorff distance (HD), Dice similarity coefficient (DSC), and volume.
RESULTS: The reduction in file size was directly proportional to the amount of mesh reduction. There were minute yet insignificant differences in volume (P>.05) across all mesh groups, with significant differences (P
METHODS: This was an observational, cross-sectional survey using a convenience sampling method conducted at the University Malaya Medical Centre (UMMC) In-Patient Pharmacy. A validated online questionnaire assessed user satisfaction and task duration.
RESULTS: A total of 21 pharmacists and 18 pharmacy assistants participated in the survey. Most pharmacists (n = 17/21) were confident in the system, and both pharmacists and pharmacy assistants perceived it to be beneficial for patients (n = 33/39) and for reducing medication errors (n = 32/39). Pharmacy assistants spent approximately 5.34 hours on traditional work including filling medication orders (1.44 hours) after automated tablet dispensing and packaging system (ATDPS) implementation. Pharmacists spent 1.19 hours filling medication orders and 1.71 hours checking/verifying them, in contrast.
CONCLUSION: Pharmacists focused mainly on clinical duties with healthcare colleagues, while pharmacy assistants handled various medication orders. Nevertheless, ATDPS reduced pharmacy staff workload in medication handling, achieving user satisfaction.
