Abstract
OBJECTIVES
We wanted to investigate the marital state and job satisfaction of female office workers.
METHODS
The data was analyzed from a cross-sectional survey of 995 female office workers. Information was obtained about the job satisfaction, sociodemographics, health behaviors, and job-related characteristics. Multiple regression analysis was used to test for the related factors of job satisfaction by marital state among female office workers.
RESULTS
The mean score of individual items on job satisfaction was significantly higher in married than in unmarried women(p=0.014). Job satisfaction was associated with stress, employment type in unmarried women, whereas it was related with employment type in married women on a multiple regression analysis (p<0.001; p=0.006; p=0.026, respectively).
CONCLUSIONS
Our findings suggest that job satisfaction is significantly higher in married than in unmarried women and it may be affected by job-related factor like employment type. Further research is needed to establish proper strategies for improving job satisfaction of female office workers.

Abstract
OBJECTIVES
To investigate the related factors on fatigue symptoms among married working women.
METHODS
Data was analyzed from a cross-sectional survey of 902 married working women. Information was obtained about fatigue symptoms, sociodemographics, health behaviors, and job-related characteristics. Multiple regression tested the related factors on fatigue symptoms in married working women.
RESULTS
Fatigue was more common in office working women than in manufacture working women. Mean fatigue symptom was significantly higher in office working than in manufacture working women(p=0.002). In a multiple regression analysis, fatigue was associated with educational level, alcohol drinking state, stress, and overtime work in a multiple regression analysis(p<0.001).
CONCLUSIONS
Our findings suggest that fatigue is affected by job-related factor like overtime work with educational level, alcohol drinking state, or stress. Further research will be needed to establish preventive strategies for controlling the negative effects of fatigue on health stats of married working women.

Abstract
Pneumoconiosis was the first reported occupational disease in Korea and was the most common one until 1990. In the past, most pneumoconiosis patients were found among underground workers in various mines. Recently this occupational disease has increasingly affected workers in manufacturing industries such as ship building, briquette, glass, foundry industries, and so on. In order to investigate the scale of pneumoconiosis in manufacturing industries, we evaluated the detailed medical examination records and insurance deliberation data from 1989 until 1994. Information about work history, medical history, and exposure dust type were collected for each member of the study population. All chest X-rays were interpreted and classified using the International Labor Organization(ILO) scale by three radiologist who have had extensive experience evaluation pneumoconiosis. For the calculation of the incidence rate of manufacturing pneumoconiosis, we analyzed the Specific Health Examination data and estimated the population at risk as a denominator of the incidence rate. We divided manufacturing industry into 9 subclasses by industrial classification and estimated the incidence rate of pneumoconiosis per 100,000 workers at risk respectively. The results were as follows, 1. 485 workers were newly diagnosed with pneumoconiosis during 6 years from 1989 to 1994. 482 workers had radiographs consistent with simple pneumoconiosis and three with progressive massive fibrosis. Among those with radiographs consistent with simple pneumoconiosis, 395 workers(81.4%) had category 1 profusion, 76 workers(15.7%) had category 2 profusion and 11 workers(2.3%) had category 3 profusion. 2. Almost all of them were male(97.9%) and their average age was 48.3 uears. Manufacturing pneumoconiosis patients were more common in their forties and fifties. 3. The average duration of dust exposure required for the occurrence of pneumoconiosis was 13.5 years. In the case of metal products manufacturing which is mostly related to welding, the average duration of dust exposure was 12.0 years. It was slightly shorter than other manufacturing industries. The average duration of dust exposure required for the occurrence of pneumoconiosis seemed to be shorter in welding operators, even though the welders lung has a weak tissue reaction and the condition is reversible. 4. According to the Industrial classification, 299 cases(61.6%) were found in workers of non-metal mineral products manufacturing, and 56 cases(11.5%) in basic metals industry. 5. The average annual incidence rate of pneumoconiosis in manufacturing industries from 1990 to 1994 was 56.6 per 100,000 workers at risk. On sub-classification, the average annual incidence rate of pneumoconiosis in non-metal mineral products manufacturing industry was the highest among them, showing 479 per 100,000 workers at risk. 6. Radiologic prevalence rate of tuberculosis in these cases was 6.6%. 7. X-ray category profusion in newly diagnosed manufacturing pneumoconiosis varied according to sub-classification. The proportion of category 1 profusion in metal products manufacturing is higher than that in non-metal mineral products manufacturing. 8. The type pattern of small round opacities varied according to sub-classification in manufacturing industry. In non-metal mineral products manufacturing, the small round opacity were observed 25.9% cases with p type, 72.1% with q type and 2.0% with r type respectively. But in metal products manufacturing, the small round opacity were observed 51.4% cases with p type and 48.6% with q type respectively. The cause might be that the exposed dust is different according to job. 9. The type pattern of small round opacities varied according to dust type. Metal dusts showed similar radiologic shape to the coal dusts, but welding fume showed more frequent p type(60.3%) and less frequent q type(377%). rock dust showed less frequent p types(18.3%) and more frequent q types(75.3%). Since the incidence rate of non-metal manufacturing workers showed higher rate than other manufacturing industry, Preventive measures and health care education should be carefully carried out in these workers.

Abstract
The possible association of colorectal adenomatous polyps, a precursor lesion for colorectal cancer, with risk factors including cigarette smoking, alcohol consumption, coffee consumption, family history and dietary factors was investigated in a case-control study. Between January 1993 and March 1995, 143 cases of patients with pathologically confirmed incident colorectal adenomatous polyps and 301 control subjects were collected from Our Lady of Mercy Hospital. Information on exposure was obtained by structured interviews. After adjustment for age and sex, statistically significant odds ratio (highest-lowest tercile) were found for cigarette smoking(5.53; 95% confidence interval CI, 3.26 9.38), coffee consumption (2.01 ; 95% CI 1. 15-3.53). For dietary factors, significant odds ratio were found for yogurt consumption (0.35 ; 95% CI 0.14-0.85) and milk consumption (0.34; 95% CI 0.17-0.70). No significant associations were observed for total fat intake and total fiber intake after adjustment for age, sex and total calorie. Odds ratio of family history of colorectal cancer and/or polyp was 3.05(95% CI 0.84-11.05). Cigarette smoking, coffee consumption, appears to be a significant risk factor, and milk consumption, yogurt consumption appears to be a significant protective factor for colorectal adenomatous polyps.
