The case was described of a 43 year old male who developed burns of the both shins as a result of handling wet cement. After wet cement was spilled into the rubber boots he was wearing, he experienced painful erythema of both lower legs. Several weeks later, medical examination revealed dirty and granulated ulceration of the both shins. The largest ulcer, about 18 by 10 centimeters, was located on the anterior aspect of left lower leg. We coneluded that this skin problem resulted from the ertreme alkalinity of calcium hydroxide in wet cement, combined with the effects of pressure and occlusion against the skin.

Concepts of Occupational Exposure Limit and Their International Comparisons: Kyung Sim Koh, Soo Hun Cho; Korean Journal of Occupational and Environmental Medicine 1995;7(1):152-168. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.152

Abstract PDF: This paper focuses on the origin of the concepts of occupational exposure limit, and traces the history and development of thoughts and regislations of various countries and organizations concerning the founding principles upon which it is based. The concepts of establishing standards for occupational chemicals in workplace air constitute a social consensus or agreement about acceptable levels of occupational hygiene. The level of scientific development of a country and the discussion of experts in the field of occupational health play an important role. The physician in occurational health has to be especially concerned to discover and estimate the risks to anyone particularly susceptible to exposures within the hygienically acceptable conditions.

Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.139

Abstract PDF: Five items among neurobehavioral core test battery of World Health Organization, including Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention, were administered to the workers occupationally non-exposed to neurotoxic agents by operational guide for the WHO neurobehavioral core test battery. Subjects were volunteers from the industrial workers (117) and clerks (40). Detailed occupational history such as exposed agents including noise or vibration, educational level, residence, smoking and drinking habit were recorded. Most of the neurobehavioral tests were correlated with age and educational level. Smoking was correlated with pursuit aiming and digit symbol. Vibration affected pursuit aiming. Job type (industrial workers vs. clerks) and noise exposure did not affected among tested items. Multiple regression analysis was done for establishing predict equation to estimate normal ranges of the tests for male workers. Age was shown to be main independent variable affected for all tests except wrong dot of pursuit aiming. Educational level was also shown to affected most of the tests except Santa ana dexterity and wrong dot of pursuit aiming. Alcohol consumption affected Santa Ana dexterity, non-preferred hand, and smoking affected only wrong dot of pursuit aiming after multiple regression analysis.

Urinary beta-Galactosidase Activity as an Early Indicator of Renal Dysfunction in Workers Exposed to Mercury Vapor: Yon Hee Oh, Kwang Jong Kim, Byung Chul Chon, Jong Tae Park; Korean Journal of Occupational and Environmental Medicine 1995;7(1):128-138. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.128

Abstract PDF: The objective of this study was to evaluate the relationship between beta-galactosidase activity in urine, in serum and urinary N-acetyl-beta-glucosarminidase activity as an early indicator of renal effect and mercurT concentration in urine and blood, reflecting the intensity of exposure to or the amount of body burden of mercury. This study was carried out among 70 workers exposed to mercury vapor and 63 non-exposed workers as a reference. The results were as follows ; 1. The mean concentration of urinary mercury (43.5 microgram/1) in exposed subjects was about nine times higher than that of non-exposed subjects, but the mean values of blood mercury were not different from each other 2. The mean values of beta-galactosidase activity in urine (119.7micromoleMU/h/g creatinine) and in blood (73.7 moIMU/H/l) of mercury-exposed subjects were significantly higher than those of non-exposed subjects. 3. In mercury-exposed subjects, beta-galactosidase activities in urine (r=0.38, p<0.01) and in serum (r=0.26, p<0.05) were correlated to urinary mercury concentration, but not to blood mercury concentration. The urinary excretion of beta-galactosidase activity was closely associated with urinary mercury concentration in the result of the multiple regression analysis. 4. The urinary beta-galactosidase activity in exposed subjects increased as the urinary mercury increased, and in the exposed subjects with more than 50microgram/1 of urinary mercury was highly related to urinary beta-galactosidase activity(r=0.47, p<0.05). 5. Among exposed subjects with more than 50microgram/l of urinary mercury, 20.0% of them showed abnormal value of urinary beta-galactosidase activity.

A Study on the Change of the Bone Density among Workers Exposed to Hydrofluoric Acid: Ji Yong Kim, Hyun Sul Lim, Hoe Kyeong Cheong, Hyeon Kyeong Lee, Heung Sik Kang; Korean Journal of Occupational and Environmental Medicine 1995;7(1):120-127. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.120

Abstract PDF

Hydrofluoric acid is one of the strongest irritating, corrosive and poisonous inorganic chemicals. The most significant chronic consequence of excessive fluoride exposure is the disorder of skeletal system and connective tissue. The first stage of osteofluorosis consists of an increase in the density of flatbone such as pelvic bone and vertebral bones, with coarseness and blurring of bone trabecular. Therefore we wanted to observe the change of the bone density among workers exposed to hydrofluoric acid. Questionnaires and radiological investigations were performed for 39 hydrofluoric acid manufacturing factory worker sexposed to hydrofluoric acid. And then authors checked urinary fluoride level by fluoride ion method. the radiographs were doubly read by two radiologists for reliability. The results were as follows; 1. There was a significant difference in urinary fluoride level (p<0.01), but not in age, in tenure(p>0.05) among workers by the job title. 2. By the two radiologists, eight cases were read as bone fluorosis. The prevalence rate of bone fluorosis was 20.5%. 3. There was not a significant difference in general characteristic such as age, tenure and in muculoskeletal signs and symptoms between the fluorosis group and the normal group. 4. However, a close relationship between the occurence of the change of bone density and the degree of fluorde exposure such as burn was found. The difficulties in diagnosing fluorosis result from the questionable sensitively of x-ray techniques and from the non-specific associated signs and symptoms. A quantitative method such as densitometry to assessosteosclerosis and bone structure alteration and a follow-up study are needed.

Brain Stem Auditory Evoked Potential and R-R interval Analysis of the Workers Exposed to Trichloroethylene: Seong Kyu Kang, Young Sook Cho, Young Hahn Moon; Korean Journal of Occupational and Environmental Medicine 1995;7(1):111-119. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.111

Abstract PDF

In order to evaluate the effects of trichloroethylene (TCE) on the central and autonomic nervous system, the brain stem auditory evoked potentials (BAEPs) and the electrocardiographic R-R interval variability (CV(rr)) were measured in three groups of workers (11) working in TCE degreasing process, workers (4) exposed to lead and two groups of workers (12) not exposed to any kinds of neurotoxicants. Two components of the CVrr reflecting parasympathetic activity (C-CV(rsa)) and sympathetic and parasympathetic activities (CCV(mwsa)) were examined. The TCE workers were exposed to TCE at the level of less than 1 hour per week while the degreasing material was changed. There were no differences in the latencies of BAEPS and CV(rr) and the components of the CV(rr) between control and TCE and lead groups. However, two lead workers had the blood lead level of less than 60 g/dl recommended as present biological guideline by the Ministry of Labor, showed the delayed latencies of V5 and I-V in BAEP. This results suggested that intermittent TCE erposure didn't affect the auditory nervous pathway and the autonomic nervous system, however, lead exposure might affect the central nervous system at the level of less than 60 g/dl in blood lead.

Assessment of Cadmium in Blood and Urine of Occupationally Exposed Workers and Renal Dysfunction by Cumulative Exposure Estimate: Seong Kyu Kang, Jeong Sun Yang, Ki Woong Kim, Jae Yeon Jang, Ho Keum Chung; Korean Journal of Occupational and Environmental Medicine 1995;7(1):101-110. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.101

Abstract PDF

88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3,8 and 7.6 microgram/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2,6) and 7.9 microgram/L(6.1 microgram/g creatinine) , resrectively. However, there was no relationship between Urinary cadmium and beta(2)-microglobulin. Cumulative exposure estimate (CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to beta(2)-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 microgram. year/m(3), which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.

Abstract PDF

This study was conducted to find out the characteristics, type of the duty and job satisfaction of health care managers at the worksite. The subjects of this study were 306 health care managers serving at worksite situated in Kyungin presently in 1994, concerning their job. Major depedent variables were health management, environmental management, and health planning related with health care managers' job; these variables were measured by nominal scale consisted of 9 items respectively. The collected data were analysed and some major results are as follows; 1. It appeared that according to the qualification of health care managers, nurses showed high performing rate in duty of health managerment and health planning, Industrial hygienist showed high performing rate relating to working environmemt managemant, and regarding their holding an additional post, the number of environmental managers held more an additionnal post than other qualified managers, thereby showing significant relatively, and however, no relation with qualification was there in decision making. 2. The performing rate relatiag to health management was significantly correlate with female, youth, unmarried, higher education, general affairs in post of duty, general employee in position, only duty of health, low monthly income and nurse. But, the performing rate relating to environmental management was significantly correlate with manufacturing industries, industrial health and safety committee, male, old age, married, long work duration, additional post, high monthly income, and hygienist and environmental managers. The performing rate relating to health planning was significantly correlate with the performing rate relating to health and environmental management, but the performing rate relating to health management was not significantly correlate with the performing rate relating to environmental management. 3. In multiple regression analysis, common major determinants of the performing duty relating to health management, environmental management and health planning were industrial health and safety committee, type of industry, education, and qualification of industry's health care managers. Additionally, age was selected as highly correlated with the performing duty relating to environmental management, and work duration and post of duty of health care managers in industry were selected as highly correlated with the performing duty relating to health planning, Based on the results indicated above, it could be understood that characteristics of the worksite-industrial health and safety committee, scale and types of industry, and characteristics of health care managers-age, education, post of duty, work duration and qualification had relations with their type of the duty. Therefore, it is required that the reference to the above-showing results such as guiding for them to precisely grasp their performing duty according to their qualification, heightening their participation in decision-making, extending the industrial health service, etc., operation and management of health care managers at the worksite should be made into being more efficient.

Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.63

Abstract PDF: For the purpose of determining the reference value of erythrocyte pyrimidine 5'-nucleotidase (P5N) activity as a biological indicator to lead exposure, this study was conducted on the total of 225 healthy men who had not been exposed to lead occupationally, in July, 1994. The parameters selected in this study were age, hemoglobin, hematocrit, number of red blood cell, mean corpuscular hemoglobin (MCH), mean corpuscular herloglobin concentration (MCHC), blood lead, and erythrocyte P5N activity. The blood lead concentrations were measured using a flameless atomic absorption spectrophotometer, and erythrocyte P5N activities by Sakai's simple method using a HPLC(1986). The results were obtaina as follows; 1. The distribution of blood lead concentrations revealed log-normal distribution, and geometric mean and standard deviation of blood lead were 4.09 microgram/dl and 1.55 microgram/dl, respectively. 2. The erythrocyte P5N activity showed normal distribution, and the mean and standard deviation of the erythroeyte P5N activity were 12.34 umole uridine/h/g Hb and 2.21 umole uridine/h/g Hb, respectively. 3. All of the selected variables including blood lead concentration did not affect the erythrocyte P5N activity. Although the erythrocyte P5N activities were negatively associated with blood lead level, the correlation coefficient was not statistically significant. 4. From the result of this study, 8.7 micromole uridine/h/g Hb was obtained as a reference value of erythrocyte pyrimidine 5'-nucleotidase activity for the healthy adult male who had not been exposed to lead occupationally.

Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.58

Abstract PDF

Urinary hippuric acid was analyzed by gas chromatography/mass spectrometry method. A simple and economical derivatization procedure using excessive methanol in acidic condition was adopted to esterify hippuric acid. Quantitative analysis was performed with two internal standards, heptadecanoic acid and hydrocinnamic acid, to evaluate the derivatization procedure as an analytical method. Using the standard addition method, linear and reproducible calibration curves were obtained for both internal standards. Calibration experiment showed that good quantitative result could also be obtained with the calibration curve obtained without urine matrix. Recovery rates for the urine samples were in the range of 95.6~111.4%. Using hydrocinnamic acid as internal standard, analysis time could be reduced.

Prevalence of Asbestosis in Korean Asbestos Industry: Do myung Paek, Nam Won Paik, Jung Deun Choi, Mi A Son, Jung Gi Im, Won Jin Lee, Young Hahn Moon, Jung Sun Park, Byung Soon Choi; Korean Journal of Occupational and Environmental Medicine 1995;7(1):46-57. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.46

Abstract PDF

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two exports familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further checked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NI0SH method 7400. The air-borno asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7~l.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 sutjects, there were 4 (3%) definite asbeatosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.

The Effect of Day and Night Shift on Risk Factors of Cardiovascular Disease in Automobile: Manufacturing Plant Workers: Jae Haek Shin, Jung Jeung Lee, Kyeong Soo Lee, Joon Sakong, Chang Yoon Kim, Jong Hak Chung; Korean Journal of Occupational and Environmental Medicine 1995;7(1):28-45. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.28

Abstract PDF: An investigation of effects of shift work on cardiovascular risk factors has been carried out on workers of a motor company in Ulsan, for 2 months from 20 April to 20 June,1993. This cross-sectional survey was designed to compare the shift workers (n=420) with day workers (n=88). The study subjects were drawn from workers who were employed in twelve hour shift system. A control group who never experienced shift work was drawn from different sections of the factory. Each worker completed a medical and occupational questionnaire and cardiovascular risk factors such as blood pressure, total cholesterol, triglyceride, apolipoprotein A-1 and B were measured. In univariate analysis, apolipoprotein B and the ratio of apolipoprotein B to apolipoprotem A-1 increased in shift workers. In multiple regression analysis for the systolic blood pressure, shift work was significant independent variable (p=0.059). In multiple regression analysis for the cholesterol, age and body mass index were significant independent variables(p<0.01), but shift work was not a statistically significant independent variable. In multiple regression analysis for the ratio of apolipoprotein B to apolipoprotein A-1, shift work was significant independent variable (p<0.05). Shift workers who have engaged in shift work more than 5 years have an excess of total cholesterol, apolipoprotein B and ratio of apolipoprotein B to apolipoprotein A-1 than those who have engaged in shift work less than 5 years (p<0.05). In multiple regression analysis for the cholesterol, duration of shift work was a significant independent variable (p=0.012). In multiple regression analysis for the apolipoprotein B and ratio of apolipoprotein B to apolipoprotein A-1, duration of shift work was not a significant independent variable.

Validity and Reliability of Data Derived from Questionnaire on Neurobehavioral Symptoms: Ho Jang Kwon, Soo Hun Cho, Hyun Sul Lim; Korean Journal of Occupational and Environmental Medicine 1995;7(1):21-27. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.21

Abstract PDF

There are many studies on the neurobehavioral symptoms due to organic solvent exposure using questionnaire. However there is little published evidence on validity and reliability of the questionnaire on the neurobehavioral symptoms. In present study, the authors tested the validity and reliability of our questionnaire, which was designed for screening neurobehavioral disturbance in organic solvent exposer. Questionnaire was administered to the workers of one paint manufacturing plant and one coil manufacturing plant. In order to evaluate validity of the questionnaire, the average questionnaire scores of two plants were compared. The average score of paint manufacturing plant were higher than that of coil manufacturing plant and the difference was statistically significant. After adjustment of age, duration of employment, education, smoking history and alcohol consumption, significance was maintained. Test-retest reliability was evaluated by kappa statistics. More than 50% of question items showed values of kappa above 0.4, Cronbach coefficient alpha whoch reflects internal consistency of the questionnaire was 0.86. Overall the data showed that validity and reliability of the questionnaire were generally acceptable.

The Relationship between Occupational Lead Exposure and Minor Hearing Impairment: Nam Hee Lee, Jong Tae Lee, Hae Lim Shin, In Guen Park, Chae Un Lee; Korean Journal of Occupational and Environmental Medicine 1995;7(1):10-20. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.10

Abstract PDF

In this study the relationship between occupational lead exposure and minor hearing impairment was investigated in a cross-sectional design with 50 lead exposed workers from January to April 1994, The data were collected from the interview with the structured questionnaire which included sociodemographic variables and medical histories especially ear disease and occupational histories. Lead exposure indices which were blood lead, urine lead, zinc protoporphyrin in urine, and delta-aminolevulinic acid in urine were analyzed, Also study subjects were examined pure-tone hearing test. The results were as follows ; 1. There were significant differences in lead indices between lead-exposed workers and non-exposed workers. 2. The duration of lead exposure did not affect the hearing impairment among lead exposed workers. 3. Minor hearing impairment were higher in lead-exposed workers than non-exposed workers, but there were not statisticatly significant. The result from this study indicated that lead exposed workers should be monitored to prevent hearing impairment and would be needed health education.

Follow up Lower Back Pain Management Method in Lower Back Pain Complaining Workers of Kyungin Area: Yong Hee Cheon; Korean Journal of Occupational and Environmental Medicine 1995;7(1):3-9. Published online February 28, 1995; DOI: https://doi.org/10.35371/kjoem.1995.7.1.3

Abstract PDF: Nine hundred and twelve workers who complained low back pain(LBP) were interviewed. After one year, 483 workers were followed showed improvement of LBP symptom. In the case of job change, it showed improvement rate of 91.2%. In case of exercise theraphy, 82.8% of workers showed improved symptom. Medical care(Clinical medication, physical theraphy and folk medicine) group showed 63.2% of improvement rate. In the presence of sciatic pain on the time of first interview, the improvement rate of LBP was lower than the absent group.
