- A man who worked in the synthetic leather manufacturing plant for 3 months died at November 3. Author review the medical record, the death certificate, and interviewed his wife and the doctor who treated him. His major job was DMF handling. At the working place, he felt severe health problem, and admitted to the hospital via emergency clinic. He complained severe abdominal pain and showed jaundice and ascites, He suffered hepatic coma and respiratory insufficiency from fulminant hepatitis from 19th days after admission. Drug abuse, hepatitis (A, B, C), and alcoholic hepatitis were rule out with his history and serological study data, As a result, author couldn't find any cause of death, but fuIminant hepatitis from DMF toxicity.

Abstract

- Twenty-four factories registered at the Ministry of Labor as factories using or producing cadmium in 1991 were investigated to know the present state of occupational exposure to cadmium in 1992.
Nine factories among 24 stopped using or changed to other substances and 1 factory didn't produce any more, but delivered it to other factories through imports. Therefore, only 14 factories were producing or using cadmium. But, alloying materials were uspplied to about 20 and more factories, however, they couldn't be investigated because of limited information.
Three factories had less than 50 workers were 3, 6 had 50-300 and 5 had more than 300. About 167 workers were exposed to cadmium.
According to the classification by process, there were 4 alloy processes, 2 refinary, 2 elctroplating, 2 dry cell making, 1 industrial battery and 1 copper refinary. 8 factories used metal cadmium, 3 cadmium oxide, 2 cadmium sulfide, and 1 cadmium hyroxide. One factory was importing cadmium stearates only and supplying them to the PVC making factories. The amount of metal cadmium producing in 2 refinary factories was about 50-65 ton per month. The other cadmium compounds were imported.
According to exposure level of cadmium in air of the 10 factories examined, each factory could be divided into high, moderate and low exposure groups. 1 battery recycling factory and 3 alloy factories were in the high exposure group and their mean air concentrations were 0.06679, 0.05481, 0.02492, and 0.003mg/m3, respectively. Refinary and industrial battery making factories were in the middle exposure group and their mean air concentrations were 0.00773 and 0.00613 mg/m3, respectively. Finally, low exposure group were copper smelting, dry cell case making, duplicator drum making and electroplating factory and their mean air concentrations were 0.00096, 0.00071, 0.00057 and 0.00054 mg/m3 respectively.

Abstract

- Lung Function test results can be influenced by race, socioeconomic status, and physical fitness. The choice of the most appropriate predictive equations should be based upon these considerations as well as age, sex, and body size. About 70% of Korean males smoke, and non-smokers can be a selective group in Korea.
In this study, lung function test results of 683 healthy Korean male workers were analyzed to get the predictive equations of Forced Vital Capacity(FVC), Forced Expiratory Volume in 1 second(FEV(1)), and FEV(1)/FVC (FEV(1)%). The age of studied workers ranged from 18to 60, and most of those finished high school or less. Healthy smokers without any respiratory symptoms or disease history were included in the study, while the effect of smoking on the test results were examined in the analysis. FVC, FEV(1), and FEV(1)% were regressed against age, height, weight and smoking status or smoking amount.
Age and height explained FVC and FVC(1) most efficiently and the contribution of other variables were not significant. Whereas, smoking was significantly associated with a decrease in FEV(1)% even among healthy un-symptomatic workers. For FEV(1)%, age, height, and smoking amount were significant variables, constituting the most efficient prediction model. The lower limit of normal for percent predicted values was calculated from lower 95 percentile as well as 95% confidence interval.
When the results of this study was compared to those from studies of white Caucasians, the predicted FVC and FEV(1) were lower for the given age and height but the differences were less than 10%. The slopes of regression equation for height and age were, however, not significantly different when the social backgrounds of the studied subjects were similar.
