AbstractAbstract PDF
OBJECTIVES
This study was carried to investigate the prevalence and odds ratio of work related musculoskeletal disorders according to the job classification in small-to-medium-sized enterprises(<300 employee).
METHODS
A questionnaire survey was given to 746 workers in 8 workplaces. 501 workers (67.2%) were finally selected in this study. The workers in the 8 workplaces was divided into 7 jobs. Those were manufacturers(metal), assemblers(appliances), cashiers, packers(cosmetics), garbage collectors, and VDT workers. Multiple logistic regression was used to estimate the odds ratios of the musculoskeletal symptoms according to the job classification.
RESULTS
Univariate analysis showed that the significantly related risk factors for musculoskeletal symptoms are as follows; age, marital status, gender, work load change, work duration, hours worked per day, job demand, decision latitude, type of job. According to the type of job, the prevalence of musculoskeletal symptoms were 7.7%(clerks), 24.3%(manufacturers), 30.0%(assemblers), 23.0%(cashiers), 30.4%(packers), 11.9%(garbage collectors), 29.2%(VDT workers). Multiple logistic regression showed that the following significant odds ratios (referenceclerks): 7.32(packers), 5.63(assemblers), 5.11(cashiers), 4.79(VDT workers), 3.11(manufacturers).
CONCLUSION
In small-to-medium-sized enterprises, the job classification was major risk factor for work related musculoskeletal disorders. According to the job classification, the odds ratios of the work related musculoskeletal disorders were different. Considering the odds ratios, the establishment of a prevention program of work related mus-culoskeletal disorders is recommended.

Incidence and related factors of fatty liver among male workers
Jin Seok Kim, Jong Young Lee, Kuck Hyun Woo, Jay Young Ryu
Korean Journal of Occupational and Environmental Medicine 2003;15(3):310-322.   Published online September 30, 2003
DOI: https://doi.org/10.35371/kjoem.2003.15.3.310
AbstractAbstract PDF
OBJECTIVE: This study was conducted to investigate the incidence rate of fatty liver and it's related factors based on a three year follow up of multiphasic health screening participants.
METHODS
671 male workers who had participated in both initial and second multiphasic health screening were selected. Initial screening was performed during the year of 1996 to 1997 and second screening was performed during the year of 1999 to 2000. Among them, four hundred and thirty workers who didn't initially have a fatty liver were selected as the final study subjects. They were classified into 2 categories according to the initial and second hepatic ultrasonographic findings; stationary normal(307, 71.4%), and fatty liver incident(123, 28.6%). The incidence rate was calculated using the incidence density method.
RESULTS
The incidence rate of fatty liver among the male workers was 9.73 per 100 person-years. The white collar workers had a higher incidence rate(10.66) than the blue collar workers(8.14). The incidence density ratio of alcohol drinking to fatty liver incidence was 1.41, and the incidence density ratio of low vegetable diet was 1.63. The incidence density ratio of obesity was 1.78 for the 100-109% obesity index group, 2.83 for the 110-119% obesity index group, 4.25 for the >or=120% obesity index group over <100%. Smoking, regular exercise, salty food preference, and taking food supplement had no significant effect on the incidence of fatty liver. The fatty liver incident group had higher initial blood pressure, GPT, gamma GTP, fasting blood sugar, HbA1c, uric acid, total cholesterol and triglyceride levels than the stationary normal group. However, there were no differences in the GOT, HDL-cholesterol or LDL-cholesterol levels. In the multiple logistic regression analysis, obesity index and serum triglyceride were found to be major factors in the incidence of fatty liver after controlling age, alcohol drinking, vegetable diet, daily coffee intake, blood pressure, HbA1c, total cholesterol, and uric acid levels.
CONCLUSION
The incidence rate of fatty liver among the male workers was 9.73 per 100 person-years. The lifestyles which gave rise to an increasing incidence of fatty liver were those involving excessive alcohol drinking, obesity, and low vegetable diet. Moreover, many cardiovascular disorder related health indices such as blood pressure, and the blood sugar, blood lipid and uric acid levels, were related to the incidence of fatty liver.

The Association of the Serum Magnesium with Hearing Loss Among Noise Exposed Male Workers
Wan Seoup Park, Jong Young Lee, Sang Jae Jung, Jae Young Yoo, Tae Sung Choi, Sung Chul Hong, Sung Chan No
Korean Journal of Occupational and Environmental Medicine 2000;12(1):12-25.   Published online March 31, 2000
DOI: https://doi.org/10.35371/kjoem.2000.12.1.12
AbstractAbstract PDF
OBJECTIVES
This study was conducted to investigate that the chronic noise exposure is associated with decreased serum magnesium concentrations and evaluate whether decreased serum magnesium is associated with noise induced hearing loss.
METHODS
One hundred seventy-eight male workers exposed to noise were selected and classified three groups by the degree of hearing loss. Hearing threshold levels were less than 30 dB at 1,000 Hz or less than 40 dB at 4,000 Hz in group I, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and 15 dB and less of pure tone average(PTA: (500 Hz+1,000 Hz+2,000 Hz)/3) in group II, more than 30 dB at 1,000 Hz or more than 40 dB at 4, 000 Hz and over 15 dB of PTA in group III.
RESULTS
Serum magnesium concentrations were 2. 42+/-0. 26 nc/dt in group I, 2. 35+/-0.23 mg(dl in group II, 2.26+/-0.24 ne/dl in group III, respectively and significantly different between group I and group III (p<0. 01). It was negatively correlated with duration of the noise exposure as correlation coefficient(r) of -0.194 (p<0.05). Analysis of the multiple regression on hearing threshold levels showed that serum magnesium, diastolic blood pressure, duration of the noise exposure were statistically significant at 4,000 Hz(p<0.05). While only age was statistically significant at 1,000 Hz(p<0.05).
CONCLUSIONS
These results suggest that chronic noise exposure may induces decrease in serum magnesium concentrations and that its decreased concentration is related with noise induced hearing loss.

Young Yeon Jung, Jong Young Lee, Kuk Hyeun Woo
Korean Journal of Occupational and Environmental Medicine 1998;10(1):29-40.   Published online February 28, 1998
DOI: https://doi.org/10.35371/kjoem.1998.10.1.29
AbstractAbstract PDF
This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Jong Young Lee, Chae Yong Lee, Ji Suk Kim, Sang Jae Lee, Wan Seoup Park, Kuck Hyeun Woo
Korean Journal of Occupational and Environmental Medicine 1997;9(2):208-216.   Published online June 30, 1997
DOI: https://doi.org/10.35371/kjoem.1997.9.2.208
AbstractAbstract PDF
To assess neurobehavioral effects of 48 low level lead-exposed workers in CRT manufacturing factory, simple and choice reaction time test with NTOS (Neurobehavioral Tests for Occupational Screening), digit symbol and digit span with K-WAIS (Korean Wechsler Adult Intelligence Scale), and SCL-90-R (Symptom Check List 90 revised) was examined. These screening test battery reflect 3 psychological domain; psychomotor, short term memory, and symptom. Average blood lead level was 17.7 microgram/dl and mean exposure duration was 5.6 years. Nobody exceeded blood lead level over 40 microgram/dl, the guideline. We divided workers to two group, shorts-term exposed group(< or = 5 years) and long-term exposed groups 5 years) for analysis. ANCOVA model of simple reaction time, hostility, phobic anxiety, somatization were statistically significant and coefficient of independent variable of exposure duration was also significant. MANCOVA model of SCL-90-R was significant, too. The results of this study were consistent with previous study; symptoms were early neurobehavioral effects of low level lead exposure. And this study showed that current blood lead level as independent variable was able to mask the early neurobehavioral effects.

Jee Sung Kim, Sung Ah Kim, Chae Yong Lee, Soon Woo Park, Si Hyun Nam, Jong Young Lee, Ji Yeon Son
Korean Journal of Occupational and Environmental Medicine 1996;8(3):477-489.   Published online December 31, 1996
DOI: https://doi.org/10.35371/kjoem.1996.8.3.477
AbstractAbstract PDF
In. order to evaluate the effects of number and method of visual stimuli on simple reaction time and determine the proper number of trials, simple reaction time of the computerized test of NTOS (Neurobehavioral Test for Occupational Screening) was carried out on 240 medical students. The prominent difference was found between male and female on simple reaction time. Regarding the effect of number based on the parameters of measures and the purpose of test itself, 64 trials was considered as proper number. The mean reaction time was different according to the methods of visual stimuli, such as color and size(p<0.05). The larger and more intence visual stimuli were, the faster sim-ple reaction time was. In respect to sex, that difference was similar. But, there was no difference depending upon whether the each result of each trial was showed on the monitor. The subjects, however, showed much interest when the result showed. Further studies, including the various variables on visual stimuli, are required to compare among various studies.

Jong Young Lee, Sang Soong Nam, Chae Yong Lee, Sung Ah Kim, Ju Young Lee, Soon Woo Park, Ji Yeon Son
Korean Journal of Occupational and Environmental Medicine 1996;8(3):546-559.   Published online December 31, 1996
DOI: https://doi.org/10.35371/kjoem.1996.8.3.546
AbstractAbstract PDF
We tried to develop Korean computerized neurobehavioral tests to promote neurobehavioral research and screening in occupational setting in Korea. This program was designated Neurobehavioral Tests for Occupational Screening (NTOS). NTOS consisted of 3 test items, choice reaction time (2 choice and 4 choice), simple reaction time (visual and auditory stimulus), finger tapping test (both hands). NTOS was administered to 120 students of medical school and to evaluate applicability. The results of reaction time tests was positively skewed but finger tapping test was negatively skewed. The only data that was not skewed was the mean frequency of finger tapping of dominant hand. The means and standard deviations of choice reaction time were 429.7 msec and 109.8 msec (2 choice), 493. 6 msec and 92.0 msec (4 choice). The results of simple reaction time were 254 msec (mean) and 55 msec (standard deviation). The mean frequency of finger tapping of dominant hand was 77.2 and that of nondominant hand was 64.9. The results of 2 choice reaction time test and finger tapping of dominant hand showed statistically significant sex difference. Factor analysis showed 2 factors, 1st reaction tests and 2nd tapping. The mean frequency of finger tapping had negative weak correlation with other reaction time test results. This computerized neurobehavioral tests may be widely applied in the other future studies, and is to be improved for the practical purpose of the occupational neurotoxico-logical area.

DOI: https://doi.org/10.35371/kjoem.1996.8.2.249
AbstractAbstract PDF
A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried :out from January; to October 1995 :among male workers of a .major iron and steel manufacturing company, located,,in Pohang. The results were as follows; 1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs (-), HBsAg(-)/Anti-HBs (+) 'and HBsAg(+)/Anti-HBs (+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2% whereas that of anti-HBs was 60.6%. 2. The proportions of HBsAg(+)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type. 3. The proportion of drinkers in HBsAg (+)/Anti-HBs (-) (73; 9%) was significantly lower than those of HBsAg (-)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (+) (84.6% and 85.7% respectively). The proportions of smoking for the three groups of HBsAg (-)/Anti-HBs(+),-HBsAg (+)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (-) were 54.3%, 53.7% and 53.0%, respectively (p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg (+)/Anti-HBs (-) was 40.1%, whereas those in HBsAg (-)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) were 21.9% and 18.4%, respectively. 4. The distribution of e Ag markers among HBsAg (+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg (+) subjects was 32.9%. In conclusion, as a screening method, EIA is. recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.

Korean Journal of Occupational and Environmental Medicine 1995;7(2):219-229.   Published online October 31, 1995
DOI: https://doi.org/10.35371/kjoem.1995.7.2.219
AbstractAbstract PDF
The relationship between occupation and risk of lung cancer was analyzed in hospital based case-control study conducted in Taegu on 168 patients with histologicatly confirmed lung cancer and age group (30-39, 40-49, etc) and sex frequency-matched 168 controls admitted into hospitals for other internal medicine problems. A self administered questionnaire was used to obtain occupation, resident environment, smoking histories and specific agent exposure histoy. The conditional logistic regression was used to estimate odds ratio for age group and sex frequency matched, after controlling for smoking status (non smoker, exsmoker, current smoker) Significant association was observed for farmer[odds ratio(OR), 1.84 , 95% confidence interval(CI), 1.16-2.94], briquette stove users(OR, 3.0 , 95% CI, 1.06-8.25), agricultural chemicals users[0R, 2.14 , 95% CI, 1.35-3.37], and welding/fume exposures[0R, 10.56 ;95% CI, 1.07~103.90]. Although there were elevated risks associated with production, home industry, transportation/storage/communication, lodgement/food worker and construction, none were statistically significant.The effect of smoking was showed significantly increased risk for exsmoker [0R, 4.50 ,95% CI, 1.99-10.16] and current smoker [OR, 3.98 , 95% Cl, 1.88-8.45] As results, although smoking is important risk of lung cancer, occupation and resident environment are showing association of lung cancer. So further evaluation is necessary for occupation risk and take preventive measures.

AbstractAbstract PDF
This study was conducted to figure out the prevalence of symptomatic peripheral arterial disease among teachers. The data used in the analysis were based on 831 questionnaires, filled out by elementary, middle and high school teachers in Taegu, between September 5, 1994 and October, 4 in 1994. The prevalence of symptomatic peripheral arterial disease was 1.7% among teachers, 1.2% for definite claudication, 0.5% for atypical claudication, 1.7% for serious illness grade I, and 0% for the walk pain grade II. The prevalence was 1.9% for the male and 1.4% for the female. The prevalence by age group was 1.3% for less than 39, 1.6% for the forties, and 2.9% for the over fifties. The results shows that the prevalence increases as the age. The prevalence was 1.8% for the smoking group, 1.6% for the non-smoking group, 2.0% for the alcohol drinking group, and 1.5% for the non-alcohol drinking group. The prevalence for the lean group based on Body Mass Index(BMI) was 1.3%, 1.8% for the normal group, 2.1% for the obese group, 2.2% for the behavior pattern A, and 1.4% for the behavior pattern B. This study shows that the peripheral arterial disease may be considered as an important health problem among teachers.

AbstractAbstract PDF
To assess the relationship of pinprick sensory threshold with height and weight, Ninety seven healthy young (age 19 to 28) males were tested on their anatomical snuff box of both Hands. Their WPT was measured by device holding and moving weighted needle sensory threshold apparatus. Mean of the WPT was 0.43(+/-0.24) g in left and, 0.53( 0.30) g in right hand. Difference of WPT between the right and left hand appeared statistically significant (p<0.01) . Correlation coefficient of WPT with height was 0.26461 (p<0.01) in left and, 0.31856 (p<0.01) in right hand. Weight was statistically significantly correlated with WPT in left hand (r=0.24932, p<0.01) The study shows that the left-right difference and influence of height in pinprick sense may exist in normal healthy male adults.

AbstractAbstract PDF
Both to determine testing frequency in bone vibrator of audiometer for measurement of vibration perception threshold(VPT) and to evaluate factors influencing VPT, ninty seven healthy adults were tested on their second metacarpal head of both hands, at 250Hz, 500Hz, 1,000Hz and so on. Measures of the VPTs at 1,000Hz were excluded in analysis because frequency 1,000Hz was not recognized as a vibration sense. Mean and standard deviation(S.D.) of the VPTs in the both hands measured at 250Hz were 19.9+/-6.7dB, 21.0+/-7.3dB, respectively and at 500Hz were 33.6+/-8.3dB, 34.9+/-8.1dB, respectively. Both mean and S.D. tended to be lower at 250Hz than 500Hz, and mean differences of VPTs between the left and the right hand at the both frequencies appeared statistically significant (p<0.01). VPTs were significantly correlated with each other (p<0.01). Age was positively correlated(p<0.001) with VPTs and education was negatively(p<0.01). Multiple regression analysis showed that age was the only factor influenced on VPT. These results suggest that, when using the bone vibrator of audiometer for measurement of VPT, the frequency 250Hz as a testing frequency may be more useful than frequency 500Hz, and VPT should be measured on both hands.
