Atypical Noise-induced Hearing Loss As a Workers'Impairment Criteria: Kyoo Sang Kim, Moon Suh Park, Seong Kyu Kang; Korean Journal of Occupational and Environmental Medicine 2002;14(3):334-345. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.334

Abstract PDF: OBJECTIVES
The problem of noise-induced hearing loss (NIHL) was objectively and systematically investigated by diagnosing three workers who complained of tinnitus and hearing disturbance.
METHODS
Atypical hearing loss is diagnosed as a work-related disease by using general medical methods, such as environmental survey, neurological examination, otoscopy, pure-tone audiometry, speech audiometry, otoacoustic emissions (OAE), auditory-evoked potentials, and interview on the history of past disease, family and occupation.
RESULTS
Three results were found according to the work-related hearing loss as follows; (1) hearing loss that is caused by exposure to continuous noise of less than 85 dB(A) or impact noise of greater than 135 dB peak, (2) mixed hearing loss that has progressed due to noise with past otitis media, and (3) atypical hearing loss that showed remarkable differences between air and bone conduction due to tinnitus.
CONCLUSIONS
The criteria for work-related hearing loss should be carefully investigated by considering exposure to impact noise, the effect of continuous noise on mixed hearing loss patients, and the hearing loss caused by tinnitus.

A Case of Reactive Dye Induced Asthma in an Exposed Worker near a Dye Factory: Kyoo Sang Kim, Jung Won Park, Chein Soo Hong, Seong Kyu Kang; Korean Journal of Occupational and Environmental Medicine 2002;14(3):326-333. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.326

OBJECTIVES
Reactive dye (RD) induced bronchial asthma is a well known form of occupational asthma. We report a case of occupational asthma due to RD in an exposed worker near a dye factory.
METHODS
To evaluate the work-relatedness of bronchial asthma, we examined all possibilities by considering the working environment and performing a personal clinical survey, such as interview on the previous history of allergic diseases, clinical and immunological investigation including skin prick tests, bronchoprovocation tests, and serial peak expiratory flow rates (PEFR).
RESULTS
Occupational asthma of internal origin was excluded by the characteristics of asthma, absence of occupational allergens, and negative PEFR result in the worker's own workplace. However, specific IgE and skin prick tests with reactive dye allergens were all strongly positive. RD challenge test showed maximal 34 % fall of FEV1 at 10 minutes of exposure (PD2 0: 2.11 mg/ml).
CONCLUSIONS
We concluded that this case was an example of bronchial asthma by external occupational allergens. This case suggests that RD induced asthma may also occur in workers and inhabitants who have lived near a reactive dye manufacturing factory.

Factors Associated With the Personal Protective Equipments(PPEs) Wearing of Workers in Small Scale Industries: Yong Kyu Kim, Hyun Joo Kim, Soo Jin Lee, Eun Chul Jang, Sang Cheol Rho, Jae Chul Song; Korean Journal of Occupational and Environmental Medicine 2002;14(3):315-325. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.315

Abstract PDF

OBJECTIVE: The aim of this study was to identify the factors associated with the wearing of Personal Protective Equipment (PPE) in small scale industries.
METHODS
In a cross-sectional study, the data were obtained from self-administered questionnaires, a special health examination and the industrial hygiene records. The study included 230 workers in small-scale industries (the print industry and automobile repair shops), which were provided with a subsidiary occupational health program funded by government in 1998. The authors used the Precede-Proceed model.
RESULTS
Among the subjects who were recommended to wear a PPE, 32.7% (35/107) wore the gas/vapor respirators, 43.9 % (101/230) wore the particulate respirators, and 44.3 % (102/230) wore hearing aids. Among them, 64.3 % (148/230) wore one of the above PPE. The wearing of PPE wearing was associated with knowledge (OR=2.34), the value of prevention (OR=3.46), social support (OR=2.78), the type of task (OR=2.18-4.47), and income level (OR=7.64).
CONCLUSIONS
In small scale industries, the proportion workers wearing PPE was low. To increase this proportion, the reinforcing, enabling, and environmental factors as well as the predisposing factors need to be modified.

Relationship between Manufacturing Workers'Job Conditions and Stress: Young A Oh, Myung Sun Lee, Kyung Yong Rhee; Korean Journal of Occupational and Environmental Medicine 2002;14(3):301-314. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.301

Abstract PDF

OBJECTIVES
In this study we performed an analysis of the stress associated with the working conditions of 6,764 workers based on 'A survey of healthy condition of workers on 1999'by the Korean Occupational Safety and Health Agency. The Purpose of this study was to provide basic data for health education and management for industrial workers'health promotion.
METHODS
Collected data were analyzed using the t-test, ANOVA and multiple regression analysis, using the SPSS 10.0 program.
RESULTS
When the degrees of stress were analyzed according to demographic characteristics, females were found to have higher levels of stress than males (p<0.001). Furthermore, as age was lowered and as the work space became larger, the degrees of a stress were also found to be higher (p<0.001 and p<0.01, respectively). When the degrees of stress were analyzed according to working conditions, longer working hours (p<0.001) and reduced break times (p<0.05), gave rise to higher degrees of stress. Also, as the work space was reduced in size and as the work intensity was augmented, the degrees of a stress were made higher (p<0.01). In terms of physical working conditions, humidity and a lack of sense of security resulted in higher degrees of stress (p<0.01). When the workers sense that their environment is noisy or dusty has poor lighting or ventilation or that the rest room and cafeteria facilities are inadequate, the degrees of stress are found to be higher. As regards the social environment, when the workers sensed that the degree of job demand or job control was higher or that the degree of social support was lower, the degrees of stress were increased (p<0.001). Among those factors which influenced physical stress in the stepwise multiple regression analysis, the primary factor was found to be the safety of the working place (5.1 %). Other factors which influenced physical stress were degree of job demand, age, work intensity, humidity, sexual discrimination, length of working hours, size of work space and the existence or not of a regular break time in this order. Total R2 due to these factors was 12%. Among those factors which influenced mental stress in the stepwise multiple regression analysis, the primary factor was the degree of job demand (4.8 %). Other factors which influenced mental stress were humidity, age, sexual discrimination, the degree of a job control, safety of the working place, degree of social support, a working site, size of the work space, quality of lighting, the existence or not of a regular break time and length of working hours in this order. Total R2 due to these factors was 13.1 %.
CONCLUSIONS
The above results shows that working conditions are strongly related to stress. Furthermore, when both physical and social working conditions are continuously managed and improved, workers may not only reduce their levels of stress but also maximize their working efficiency.

Cost of Work-related Cerebrovascular and Cardiac Disease: Hyeong Su Kim, Soung Hoon Chang, Jae Wook Choi, Kun Sei Lee, Cheong Sik Kim, Jun Young Lee, Ji Young Oh; Korean Journal of Occupational and Environmental Medicine 2002;14(3):288-300. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.288

Abstract PDF: OBJECTIVES
The purpose of this study was to estimate the cost, with a focus on forecasting the expenditure on industrial accident compensation insurance, arising from workrelated cerebrovascular and cardiac disease.
METHODS
We used a total of 4,480 work-related cerebrovascular and cardiac disease data points, collected between 1995 and 2000, based on the year of occurrence, and which had been approved by industrial accident compensation insurance. Firstly, we calculated the number of approved cases per 100,000 workers benefiting from industrial accident compensation insurance between 1995 and 2000. We then forecasted the numbers of work-related cases of cerebrovascular and cardiac disease for the period from 2001 through 2005 using a linear regression equation. Secondly, we analysed the expenditure on industrial accident compensation insurance due to work-related cerebrovascular and cardiac disease, and estimated the expenditure per capita for the former period. Thirdly, we estimated the expenditure on industrial accident compensation insurance due to work-related cerebrovascular and cardiac disease for the latter period based on the cohort of occurrence year.
RESULTS
Approved cases per 100,000 workers for work-related cerebrovascular and cardiac disease were 3.36 in 1995 and 13.16 in 2000. It is expected that the approved cases would be 1,336 (95 % CI 1,211-1,460) in 2001 and 1,769 (95 % CI 1,610-1,931) in 2005, based on the year of occurrence. The mean expenditure per capita was estimated to be 75 million won, which comprised of 19 million won for medical care benefits and 56 million won for other benefits. It was anticipated that the claims for the 2001 cohort would be 107.9 billion won and 192.4 billion won for the 2005 cohort.
CONCLUSIONS
The magnitude of the economic burden of work-related cerebrovascular and cardiac disease is substantial. From an economic perspective, this study proves the importance and need for the management of work-related cerebrovascular and cardiac disease.

The Effects of Job Stress on the Autonomic Nerve Activity of Workers in Manufacturing Industry: Ki Jung Yoon, Mi Na Ha, Jai Young Kim, Sang Yun Lee, Hyoung June Im, Ae Sun Shin, Seung Sik Hwang, Jeong Soo Kim, Dae Hee Kang, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 2002;14(3):280-287. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.280

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.

A Study on Liver Function Indices in Male Lead Workers: Young Hwangbo, Yong Bae Kim, Gap Soo Lee, Sung Soo Lee, Kyu Dong Ahn, Byung Kook Lee; Korean Journal of Occupational and Environmental Medicine 2002;14(3):270-279. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.270

Abstract PDF

OBJECTIVES
To evaluate the effects of lead on the liver function indices in male lead workers.
METHODS
The study comprised of 274 lead workers and 113 non-lead workers who were confirmed not to have HBsAg (Hepatitis B surface Antigen). Blood lead (PbB), blood zinc protoporphyrin (ZPP) and urinary delta-aminolevulinic acid (ALAU) were selected as parameters for monitoring exposure to lead while aspartate aminotransferase (SGOT), alanine aminotransferase (SGPT) and gamma-glutamyltransferase (gamma-GTP) were chosen as parameters for monitoring liver function. Demographic information, such as age, smoking and drinking histories were collected. The duration of work for the lead workers, and their BMI(body mass index), were also obtained.
RESULTS
After adjusting for possible confounders {age, BMI, work duration, smoking (pack-year) and drinking (bottles of Soju consumed per week)}, blood lead was observed to be a significant variable from the logistic regression analysis of the abnormalities of SGOT( >35 IU/L), with an odds ratio of 1.04 (95 % CI, 1.008-1.066). The amount of alcohol drunk (odds ratio 1.28: 95 % CI, 1.054-1.549) and BMI (odds ratio 1.24: 95 % CI, 1.075-1.421) were also significant variables. From the multiple linear regression analyses, blood lead was significantly, and positively, associated with SGOT (p<0.05).
CONCLUSIONS
These findings suggest that exposure to lead may have an effect on SGOT in male lead workers.

The Effects of Diethyldithiocarbamate on the Metabolism and Hepatotoxicity of Trichloroethylene: Byung Sun Choi, Jung Duck Park, Yeon Pyo Hong; Korean Journal of Occupational and Environmental Medicine 2002;14(3):257-269. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.257

Abstract PDF

OBJECTIVES
The purpose of this study was to evaluate the trichloroethylene (TCE) metabolism, acute toxicity, and the effects of diethyldithiocarbamate (DDTC) on the acute toxicity in TCE-intoxicated rats.
METHODS
TCE was administered orally at doses of 600, 1,200 and 2,400 mg/kg of body weight following pretreatment with either saline or 500 mg/kg of DDTC. 12 hours after administration of TCE, the concentrations of TCE, trichloroacetic acid (TCA) and trichloroethanol (TCEOH) in the blood and solid organs, and the histopathological changes in each organ were examined.
RESULTS
The level of CYP2E1 markedly decreased in the DDTC-pretreated groups. The CYP2E1 content in the TCE-treated rats increased in a dose-dependent manner. The concentrations of TCE and TCEOH were highest in the liver, and the level of TCA was highest in the blood. The DDTC-pretreated rats had a markedly increased level of TCE and decreased levels of TCA and TCEOH, than the rats pretreated with saline. These findings indicated that CYP2E1 was important in the metabolism of TCE. From the histopathological findings, centrilobular necrosis was observed in the livers of the TCE-treated rats, but no significant change was found in those rats pretreated with DDTC.
CONCLUSIONS
DDTC is considered to be effective in protecting TCE-induced hepatic damage because it inhibits the TCE metabolism.

Effects of Health on Shift-Work: General and Psychological health, Sleep, Stress, Quality of life: Yoon Gyu Kim, Dong Young Yoon, Jung Il Kim, Chang Ho Chae, Young Seoub Hong, Chang Guk Yang, Jung Man Kim, Kap Yeol Jung, Joon Youn Kim; Korean Journal of Occupational and Environmental Medicine 2002;14(3):247-256. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.247

Abstract PDF

OBJECTIVES
This study was performed to investigate the effects of shift-work, in terms of general health concepts, insomnia, stress, quality of life and psychological health, at several manufacturing plants.
METHODS
Questionnaires were distributed to 850 shift-workers (study group), and to 550 non-shift workers (as a control group). The questionnaires included questions on ; general health concepts, insomnia, stress, quality of life and psychological health. 455 shift-workers and 372 non-shift workers completed the questionnaires, and the factors influencing the health status and quality of life in workers estimated by multiple iogistic regression analysis.
RESULTS
From the general health questionnaires, the mental health and health perception were significantly different between the shift and non-shift workers, with the better being former than the latter (p<0.05). Shift-workers complained of more insomnia when adjusted for age, working period, education and job satisfaction. Greater job satisfaction, was coupled with less complaints of insomnia (p<0.05). There were 200(43.96 %) shift workers classified as insomniac, whereas with the non-shift workers this figure was 84 (25.15 %), showing a significant difference between the two groups (p<0.05). Shift-workers were more stressed than the non-shift workers in their daily lives, which also showed significant difference (p<0.05). Less job satisfaction, was coupled with more complaints of stress (p<0.05). The quality of life of the shift-workers was lower than that of the nonshift workers (p<0.05). With the shift-workers complaining of more anxiety than the nonshift workers (p<0.05).
CONCLUSIONS
Our results suggest that shift-workers suffer from physical and psychological distresses, sleep problems and stress than non-shift workers. Furthermore, it is presumed that these factors might negatively affect the quality of life of shift-workers. Accordingly, interventional methods for shift-worker's health and quality of life as a result of adverse effects of shift-work are needed.

Age-dependent Effect of Metabolism and Testicular Toxicity to di(2-ethylhexyl) Phthalate: Yeong Ju Park, Byung Sun Choi, Jung Duck Park, Yeon Pyo Hong; Korean Journal of Occupational and Environmental Medicine 2002;14(3):236-246. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.236

Abstract PDF

OBJECTIVES
The purpose of this study was to evaluate the age-dependent response of testicular toxicity and the mechanism of di(2-ethylhexyl) phthalate (DEHP) induced testicular toxicity.
METHODS
DEHP was administered orally in doses of 0, 1.0 and 2.0 g/kg/day, for 7 days, to 3, 6 and 9 week-old Sprague-Dawley rats. Testicular weight and sperm head counts, plasma level of DEHP, mono(2-ethylhexyl) phthalate (MEHP) and testicular lipid peroxidation were measured. Histopathological changes in the testis were observed.
RESULTS
Reductions in weight gains, and relative testis weights, were observed in the 3 week-old rats in a dose-dependent manner, but not in the 6 and 9 week-old rats, compared to those of the control rats. Sperm head counts were decreased in the 6 week-old rats exposed to 2.0 g/kg/day, but not in the 9 week-old rats. Testicular atrophy and significant size reduction of the seminiferous tubule were observed in a dose-dependent manner in the 3 week-old rats. The plasma concentrations of MEHP were higher than those of DEHP, with these levels being most elevated in the younger rats. Lipid peroxidation, following exposed to DEHP, was increased in a dose-dependent manner in the 3 week-old, but with no changes in the 6 and 9 week-old rats.
CONCLUSIONS
Our results suggest the age related difference observed in the testicular response to the oral administration of DEHP may be due to the metabolism, and that oxidative stress may be related to the mechanism of DEHP induced testicular toxicity.

A Study on the Relationship between Emotional Labor and Depressive Symptoms among Korean Industrial Service Employees: Soo Youn Kim, Sei Jin Chang, Hyoung Ryoul Kim, Jae Hoon Roh; Korean Journal of Occupational and Environmental Medicine 2002;14(3):227-235. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.227

Abstract PDF

OBJECTIVES
This study was designed to identify the relationship between emotional labor and depressive symptoms among Korean industrial service employees.
METHODS
The case group consisted of 331 employees who were performing emotional labor at department stores, hotels, and family restaurants in Seoul. The control group in this study consisted of 150 employees (90 officers in Seoul and 60 manufacturing workers in Incheon) who were not expected to perform emotional labor. A structured questionnaire was used to estimate each participants level of emotional labor, general characteristics, job content, job satisfaction, and any depressive symptoms. The measurements for emotional labor were performed only on the case group and not the control group.
RESULTS
While the mean values of job satisfaction, job insecurity, and the level of depressive symptoms of the employees who were working in the area of emotional labor were higher than the others, the mean values of job demand, and job control in the same group were lower than those who were not performing emotional labor. Overall, it was found that performing emotional labor and having high levels of job insecurity were related to increased depressive symptoms, and conversely, job satisfaction played a role in reducing depressive symptoms. Similarly, in the sub-sample of the emotional labor group, high levels of job insecurity, and performing high degrees of emotional labor, and low job satisfaction were associated with depressive symptoms.
CONCLUSIONS
These results suggest that performing emotional labor is related to an increase in depressive symptoms. In other words, involuntary emotional expression and low job satisfaction in the workplace may influence the level of depressive symptoms in workers. It is, therefore, imperative that further research be undertaken, which considers the importance of emotional labor, and its adverse effect on the mental health of service workers.

Carpal Tunnel Configuration Measured by Ultrasonography as a Risk Factor of Carpal Tunnel Syndrome in Motor Part Manufacturing Workers: Duck Soo Kim, Hae Kwan Cheong, Hyun Sul Lim, Yong Wook Kwon, Jong Min Lee, Dae Hyun Cho, Dae Seob Choi; Korean Journal of Occupational and Environmental Medicine 2002;14(3):213-226. Published online September 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.3.213

Abstract PDF

OBJECTIVES
This study was conducted to evaluate individual susceptibility to carpal tunnel syndrome (CTS) by ultrasonographic measurement of the carpal tunnel configuration in workers doing repetitive work.
METHODS
The study subjects consisted of 24 male and 11 female workers in a soundproof material manufacturing company in Gyeongju. We conducted a self-reported questionnaire survey, a physical examination and an electrodiagnostic study (EDS) in April 2000. After the examination, jobs were rearranged for workers with CTS. A follow up physical examination, EDS, and measurement of the carpal tunnel by ultrasonography was done six months later.
RESULTS
Of those studied, prevalence of CTS was 63.6/100 persons among women and 29.2/100 persons among men. Mean depth and width of wrist was shorter in those with CTS compareal to the controls (p<0.05). The risk of CTS was higher in workers whose carpal tunnel ratio (displacement/width) was 0.17 or higher (OR 7.13, 95 % confidence interval 1.18-43.1), and in workers whose carpal tunnel area was less than 300 mm2 (OR 8.00, 95 % confidence interval 1.18-68.5). Carpal tunnel depth and depth/width ratio had a positive correlation with motor latency of the median nerve and median-ulnar sensory latency difference (p<0.05), whereas the carpal tunnel width, displacement/depth ratio, and area (width X displacement) had a negative correlation with median nerve latencies after adjusting for gender. Workers who showed an improvement in the clinical stage of CTS after job rearrangement had a significantly lower carpal tunnel displacement/width ratio and displacement/depth ratio. They also had smaller upper carpal tunnel area ( width X displacement) and larger upper carpal tunnel area [(depth-displacement) X width] than the controls (p< 0.05 ).
CONCLUSIONS
Ultrasonographic measurement of the carpal tunnel is a good predictor of susceptibility and prognosis of CTS in workers doing repetivive work.
