In July 1997 at 7 pm , 49 members 0f the public complained of dizziness, sore throat, eyes irritation and tightness of chest after exposed to sulphur dioxide while traveling on the road about 100 meter 90m the sulphuric acid factory in Teluk Kalong Kemaman. The incident was caused by leaking sulfur dioxide from return pipe of scrubber circulation. tank in the factory. The problem had occurred due to carelessness of the operator to inspect the level of water in the scrubber circulation tank during the operation.
An investigation was undertaken 0f a malaria outbreak in Felda Neram 1 in the district of Kemaman,
Terengganu. Thirty-eight malaria cases of Plasmodium falciparum with one death were reported from that locality. The outbreak peaked between the epidemiological week of 42 and 44. A total of 2300 persons were surveyed with population coverage of 90%. Overall Slide Positive Rate was 1.5%. Out of 38 cases, 19 were Malays and the rest were Indonesian workers. Seventy-nine percent (30/38) had a history of fever within nine weeks prior to the survey. Thirty persons were found to be febrile on the.date of the survey of which 42% (14/30) were smears positive. Blood smears showed 65.7% (25/38) had an asexual parasitemia and 34.2% (13/38) cases were gametocytaemic. The males0”emales ratio was 1:7. Younger age groups were more ajfected. All patients were given radical malaria treatment. F orty-three percent (16/38) had a second course of radical treatment. The outbreak was caused by the re-entry of an Indonesian worker with malaria to the locality. Factors such as delayed detection and notyication and inadequate surveillance were instrumental for the outbreak.
The aim of this study was to identify the problems of stress and health effect among the office computer users. A total of 41 office workers whose job required the use of computers. A set of constructed questionnaire were use to measure the work stress and health problems among workers. The data was analyzed by using of descriptive and inference statistic. The result showed that subjects who use computer for more than 2 hours would experienced work stress such as fatigue 29(70.7%), eye and visual symptoms such as blurring of vision 27(65.9%) and musculoskeletal pain at neck 32( 78.6%). However most of symptoms were moderate. There were a significant relationship between the time spent of using computer with problem of stress (r= 0.440, p<0.05) and eyes and visual problem (r=0.319, p<0.05). However there was no significant relationship between the work station design with stress, musculoskeletal, eye and visual problems. Therefore the longer time spent using computer will lead to health problems. Using the safety operating procedure will reduce the work stress problems.
