Abstract PDF: OBJECTIVE: A cross-sectional study was conducted to evaluate the relationships between autonomic nerve activity (i.e., heart rate variability and urinary catecholamines) and job stress.
METHODS
The study was conducted on 134 workers from a company producing consumer goods (i.e., diaper, paper towel) located in Cheonan, Korea. Job stress was assessed by Karasek's Job Content Questionnaire (JCQ). Autonomic function was assessed by heart rate variability (HRV) and urinary catecholamines (epinephrine, norepinephrine, and dopamine). Urine samplings, and measurings of HRV, were repeated three times for each shift. Information on demographic characteristics, previous job histories, past medical history, smoking and drinking were also collected.
RESULTS
No statistically significant differences were observed in any HRV and urinary catecholamines among the four groups, which were categorized by the Job Strain Model. When data were stratified by work duration, low field HRV was borderline significantly higher in the high strain group in individuals with a shorter work duration (<48.5 months, N=28, p-value of 0.92 by analysis of variance).
CONCLUSIONS
Neither HRV nor urinary catecholamines are significantly associated with job stress, as assessed by the Karasek's JCQ. However, HRV seems to be a potential physiological indicator of job stress only in the workers with a shorter work duration.

The Association of Workplace Cumulative Noise Exposure and Blood Pressure: Sang Yun Lee, Jai Young Kim, Hyoung June Im, Ki Jung Yoon, Hong Ryul Choi, Sang Baek Koh, Dae Hee Kang, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 2001;13(2):200-208. Published online June 30, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.2.200

Abstract PDF

OBJECTIVES
The association of workplace cumulative noise exposure and blood pressure was investigated in this study using cross-sectional design.
METHODS
The study population comprised 852 manufacturing male workers of whom occupational health examination data, questionnaire and personnel records were available. Workplace ambient noise monitoring data was used for calculating individual cumulative noise exposure level. Mean of each systolic and diastolic blood pressure of occupational health examination data was used for individual systolic and diastolic blood pressure level. Possible confounding variables including family history of hypertension, smoking habit, alcohol drinking habit were collected by questionnaire. On the basis of job location and duration of work at the location, a cumulative time-weighted average noise level was calculated for each workers. According to this cumulative noise exposure level, each study subject was categorized as low noise exposure group, moderate noise exposure group, high noise exposure group, very high noise exposure group. Among noise exposure groups, mean of systolic and diastolic blood pressure was compared after adjusting possible confounding variables such as age, body mass index, serum cholesterol level, family history of hypertension, smoking history, alcohol drinking habit.
RESULTS
After adjusting possible confounding variables, noise exposure group was significant explanatory variables for both systolic and diastolic blood pressure, and mean of both systolic and diastolic blood pressure of very high exposure group was higher than that of low exposure group.
CONCLUSIONS
These findings suggested that the high cumulative noise exposure might elevate the blood pressure.

A case-crossover study between air pollution and hospital emergency room visits by asthma attack: Hyoung June Im, Sang Yun Lee, Ki Jung Yun, Young Su Ju, Dae Hee Kang, Soo Hon Cho; Korean Journal of Occupational and Environmental Medicine 2000;12(2):249-257. Published online June 30, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.2.249

Abstract PDF

OBJECTIVES
This study, using case-crossover design, search a relationship between changing levels of air pollutants and asthma attack in asthma patients.
METHODS
We searched the daily total number of asthmatic patients at hospital' s emergency room in Seoul, Korea by investigating total 49 general hospitals emergency room records. Otherwise, We investigated medical records of asthmatic patients at one of the 49 hospitals we have searched. We investigated addresses that they are living, diagnosis, smoking history, whether respiratory infection or not, medications. We analyzed the data by 1:m conditional logistic regression used when matched case-control study is analyzed. Control periods were chosen by bidirectional paired matching technique 7, 14 days before and after case periods.
RESULTS
the relative risk of asthmatic attack by 100 ppm ozone increase between June and September were 1.348(95 % CI = 1.010~1.619). Between November and February, the relative risk by 100 /m TSP increase, 100ppb sulfur dioxide and nitrogen dioxide were respectively 1.278(1.010~1.619), 1.237(1.019~1.502), 1.285(1.006~1.640). In stratified analysis, the relative risk were significant when the asthmatic patients were children aged 15 years or below, when there were respiratory infection, and when the patients took medications irregularly CONCLUSIONS: There was statistically significant association between ambient levels of air pollutants and asthmatic attack. So, we have to exert our efforts to minimize the air pollution effectively, to protect public health from air pollution.

Biomarkers of Susceptibility in Bladder Carcinogenesis: Sue Kyung Park, Hae Won Jung, Dae Hee Kang, Keun Young Yoo, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 1997;9(2):341-356. Published online June 30, 1997; DOI: https://doi.org/10.35371/kjoem.1997.9.2.341

Abstract PDF: Owing to the development of molecular biological techniques to identify new biomarkers of bladder cancer, the information obtained from the studios in which newly developed biomarkers are applied potentially useful in screening of general population, diagnosis of patients, predicting biological behavior and prognosis, and exposure assessments. Despite of rapid development there are a few review about the biomarkers in bladder cancer from which grogs summary of results as well as their optimal function can be considered. This study was carried out in biomarkers of bladder cancer by reviewing the literature to assess the usefulness and stapes of researches for biomarkers of bladder cancer on high risk groups, general population and patients. The biomarkers of bladder cancer were classified by Weinstein's model of carcinogenesis, simple classification of exposure-discase in classical epidemiology, classification by conception of exposure-disease continuum on molecular epidemiology, and application of biomarkers. Two biomarkers, N-acetylation enzyme and Glutathion S-transferase, which had been studied extensively in molecular epidemiology were selected and reviewed. Although the generalization, prediction and diagnosis of bladder cancer based on a single biomarker give rise to trouble due to intravariation of bladder tumor and heterogeneity of biomarkers variation, searching for more specific tumor markers may accurately lead better prediction of prognosis and better estimation of treatment response. The usefulness of both N-acetylation enzyme and glutathion 5-transferase in high-risk groups who have exposes to carcinogen may be more valuable. However more informations are neede in order to apply these biomarkers in clinical practices in further studies.
