Job stress has now become one of the most significant health and safety issues in the workplace and one of the least understood areas of organizational cost. A cross-sectional study to assess job strain and dissatisfaction in lecturers of the School of Medical Sciences, Universiti Sains Malaysia (USM) was undertaken between August 2001 and May 2002. The original English version of the Job Content Questionnaire (JCQ) version 1.7 (revised 1997) by Robert Karasek was self-administered to 73 (response rate 58.4%) lecturers in School of Medical Sciences USM. The prevalence of job strain (defined by low decision latitude and high psychological demands) in USM was 23.3%. The risk factors of job strain in the lecturers were psychological stressors (adjusted OR 1.2, 95% CI 1.0, 1.4), created skill (adjusted OR 0.4, 95% CI 0.2, 0.8) and working in clinical-based departments (adjusted OR 18.7, 95% CI 1.6, 22.7). The prevalence of job dissatisfaction was 42.6%. Associated factors of job dissatisfaction in USM lecturers were decision authority (p < 0.001) and psychological job demand (p < 0.001). We conclude that psychological stressors and created skill were non-protective and protective, respectively, against job strain in USM lecturers. Clinical-based lecturers experienced higher job strain compared to non-clinical-based lecturers. Psychological job demand was strongly associated with job dissatisfaction, and decision authority was protective against job dissatisfaction.
A cross sectional study to determine the exposure of heat and its biological effects on the workers in a plastic factory located in the Shah Alam Industrial Estate, Selangor, Malaysia. Forty five respondents from the polymer section in the factory were selected as the respondents. Variables measured were the environmental temperature (WBGTin), air velocity, relative humidity, body temperature, average heart and recovery heart rate. QUESTEMP°34 Area Heat Stress Monitor was used to measure the environmental temperature in °C (WBGTin) and relative humidity (%). Velocicheck Model TSI 8830 was used to measure the air velocity in meter per second (m/s) while the OMRON Blood Pressure Monitor Model T3, was used to measure average heart rate and recovery heart rate. Body temperature (°C) was measured by the Instant Ear Thermometer-OMRON Gentle Temperature Model MC509. Interviews using questionnaires were used to determine respondents’ socioeconomic background, previous risk factors on heat exposure and other information related to heat stress. Results showed that the mean environmental temperature for the exposed group was 28.75°C, the mean air velocity was 0.15 m/s and the mean relative humidity was 58.1%. These production workers were exposed occasionally to heat when loading plastic powder into the molds as well as demolding the finished plastic products from the molds. The average time of monitoring was 2 hours for intermittent exposure and 8 hours duration for overall exposure. Maximum demand for work load was measured 1 minute after work activities were stopped at the demolding section. There was a significant difference between body temperature and average heart rate before work, after 2 hours of work and after 8 hours of work ( p < 0.001). The mean recovery heart rate after 1 min was 88.0 ± 12.0 beat per min. (bpm), indicating that there is no excessive physiological demand. Body temperature (36.8 ± 0.40°C) and average heart rate after 8 hours (78 ± 12 bpm) indicated a good body control of heat exposure. Five out of six workplaces monitored had temperatures of greater than 28°C (ACGIH TLV). The workers were exposed to moderate heat stress during the study period, however, body temperature and average heart rate measurement did not reach unacceptable level of physiologic strain.
As part of an organizational review of safety, interviews and questionnaire surveys were performed on over 700 commercial goods drivers and their managers within a series of related companies operating across 17 countries. The results examine the reported incidence of fatigue-related problems in drivers and their associations with near miss and accident experience as well as work and organizational factors. Experience of fatigue problems while driving was linked to time of day and rotation of shifts, though most associations were small. There were significant associations found between fatigue experiences and driver and management systems of break taking and route scheduling. The quantitative combined with qualitative information suggested that, where feasible, more flexible approaches to managing the scheduling and sequencing of deliveries assisted drivers in managing their own fatigue problems through appropriate break-taking. The results are interpreted within the overarching principles of risk assessment and risk control.
Corporate culture can simply be defined as “The way we do things around here". It comprise of assumptions, values, norms and tangible signs. Ministry of Health has started its culture building in 1991. Prior to this study, there have been two studies to evaluate its implementation. There were two types of respondents, where administered questionnaires were sent to all head of departments and all U3 medical ojjicers in public services in Malaysia, About 50% (n=126) of head of departments and only 18% (n=1321) of medical ojjicers responded. The study shows that at least 83% of head of departments perceived that the three core value of corporate culture has been implemented in their departments. However for rites and rituals, less than habf of them have implemented it. Singing of corporate song is done more in hospital as compared to health. As for medical officer, only 28% of them have received training on corporate culture. Among those who have received training, only a quarter understood the meaning of corporate culture. Doctors were also asked to give opinion on how to generate a caring doctor. About one-third suggested to reduce the workload of doctors. Apart from increasing manpower, workload can also be reduced by reengineering the system and upgrading the doctors’ competency.
The author tested for the 3 possible pathways (i.e., direct, moderator, and mediator effects) in which locus of control can influence the relationship between work-family conflict and well-being. The author predicted that work-family conflict would be negatively correlated with well-being. In a sample of 310 Malaysian employed women with families, work-family conflict was a significant predictor of both job satisfaction and distress--negatively related to job satisfaction and positively related to symptoms of distress. More important, the results provided support for the effects of all 3 pathways of control on the relationship between work-family conflict and well-being, depending on the outcome measure: For job satisfaction, locus of control had direct effects, acted as a partial mediator, and played a significant moderating role. In contrast, only the direct effect of locus of control predicted distress. The author discusses those findings with reference to the literature on work-family conflict, locus of control, and the issue of stress-distress specificity.
With the increasing ease of travel and the passage of peoples between counkies there is a need to ensure that the recipient country is not burdened by the need for care of ilniiiigrant with health problems as well as the increased risk posed to the local population froni exposure to conun~unicabled isease. To assess the chest radiographs of a selected group of inun~igrantsto ascertain the presence of abnormalities especially the presence of tuberculosis. A total of 250 imniigrants were prospectively evaluated by a PA chest radiograph. The chest radiograph was evaluated by two radiologists for the presence of abnormalities of the heart, lungs, mediastinum and bony rib cage. There were 112 Indonesians, 133 Bangladeshis, one Myanmar, three Pakistanis and one others. Males made-up 222 while there were 28 females. The chest radiograph was diagnostic in all cases. There were 13 cases with enlarged hearts but with no evidence of heart failure. There was only a single inlmigrant who had evidence of active TB though there were 6 others who had evidence of old disease. There was evidence of other infections in five. With regard to the mediastinuni there was a single case with enlarged hila probably secondary to increased cardiac output. There were 21 patients with scoliosis of the spine and two with abnormaIities of the ribs. Even though there was a single case with evidence of TB from this pilot study, from unreported data from the UMMC, there were 15,16 and 23 immigrants treated for TB for 1994,1995 and 1996 respectively. This was mainly seen in the Indonesians followed by the Bangladeshis and Myanmar. We attribute this discrepancy to the biased salnpie in this study where probably only the healthy were seen while those who were not well did not want to participate in this study. In addition, this may also be due to the small sample used in this study. We feel that screening of the immigrants out in the field may be able to detect cases of active TB. As for the large hearts we feel that in the absence of any cardiac symptoms and other radiological changes these are probably due to the increased workload on the heart from physical activities. This is a recognised presentation. The changes in the mediastinum and bony rib cage are probably not very significant.
Eight general practitioners participated in a survey of content of general practice. This is useful as an indicator or morbidity in the community as well as of workload of general practice. A total of 3164 consultations were recorded, of which 2764 (87%) were because of an illness and the rest (13%) for other reasons like medical examinations, antenatal check, family planning advice, pregnancy tests, pap smear and vaccination. The old and the young have high consultation rates for an illness, men consulted as often as women. The most common illness seen was upper respiratory tract infections, accounting for 37% of all illnesses. Other common minor illnesses were skin infections (6%), genito-urinary infections (5%), minor musculoskeletal (6%) and gastrointestinal (6%) complaints as well as minor injuries and cuts (4%). Major disorders form an unusually low proportion (18%) of all illnesses seen, in comparison with figures from United Kingdom. The common major disorders seen were hypertension, asthma, chronic rheumatic disorders and diabetes. Circulatory disorders were remarkably rare, accounting for only 1% of illnesses. Psychological disorders, both major and minor, were also rarely seen, accounting for only 1% of illnesses which is in marked contrast with figures from the United Kingdom. Factors contributing to these notable findings are discussed.
