AbstractAbstract PDF
Since 1964, when the official statistics on occupational injury rates had been produced for the first time, the rates have showed a steady decline until 2000. However, the injury rate has been stagnant since 2000 although the fatal injury rate has decreased 40% in the same period. The non-fatal injury rate per 100 employees was 0.63 while the fatal injury rate per 100,000 employees was 9.74 in 2010. Traumatic injuries accounted for 86.8% of all injuries, followed by non-traumatic injuries at 8.4% and injuries by traffic accidents at 4.6%. Injuries caused by being caught in objects, hit by flying or falling objects and collisions have decreased while those caused by slip and fall on same level and fall from the height have increased. The decrease in injuries caused by being caught in objects may be the result of prevention efforts because 68.6% of them occurred in the manufacturing industry where most efforts for prevention have been invested. The increase in injuries involving slips and falls on same level may be caused by the growing number of employees in the service industry where 51% of the cases occurred. The construction industry accounted for 40.2% of all fatal injuries, and falls from the height caused 54.3% of the fatality. The non-fatal injury rate of Korea is lower than that of industrialized countries while its fatal injury rate is comparatively higher. It is probably caused by many unclaimed cases of mild non-fatal injuries whereas most fatal injuries were filed. Another problem is that the injury rate does not include injuries that occur to workers who are not eligible for the compensation scheme. This information can be obtained through a surveillance system or the national survey. Therefore, the attention of occupational physicians should focus on injuries as well as diseases occurring at work, and also on all working population whose injuries and diseases are not covered by the compensation scheme.

Exposure Level of Trichloroethylene in Stevens-Johnson Syndrome Due to Occupational Exposure: 3 Case Reports and a Review of Other Cases
Sun Wung Lee, Eun A Kim, Dae Sung Kim, Dong hee Koh, Seong Kyu Kang, Byung Kyu Kim, Min Ki Kim
Korean Journal of Occupational and Environmental Medicine 2008;20(2):132-146.   Published online June 30, 2008
DOI: https://doi.org/10.35371/kjoem.2008.20.2.132
AbstractAbstract PDF
BACKGROUND
Trichloroethylene (TCE) has been reported to be related to severe generalized exfoliative dermatitis frequently accompanied by toxic hepatitis. The measurements of environmental exposure were limited in the previous case reports and the reported exposure values were also diverse. We reviewed three cases of Stevens-Johnson syndrome associated with TCE. The work environment was measured by the Korea Occupational Safety and Health Agency (KOSHA) after the cases occurred. From the study results, we intended to clarify the relationship between TCE exposure level and Stevens- Johnson syndrome.
CASE
REPORT: Case 1. A 24-year-old Filipino female worker developed a skin rash 35 days after starting to use TCE for degreasing. The skin rash developed into a bullous eruption and the liver function findings were abnormal. She was diagnosed with Stevens-Johnson syndrome and toxic hepatitis. She died of hepatic failure 39 days after the onset of the first symptom. She had no previous history of taking medicine or viral infection. The work environment measured 22.0 to 32.3 ppm (personal exposure level) with TWA. Case 2. A 47-year-old Korean male worker developed a skin rash, 20 days after starting to use TCE for degreasing. The skin rash developed into a bullous eruption and the liver function findings were abnormal. He was diagnosed with Stevens-Johnson syndrome, toxic hepatitis and sepsis. He died of hepatic failure and sepsis 42 days after the onset of the first symptom. He had no previous history of taking medicine or viral infection. The work environment measured 30.1 ppm (personal exposure level) and 116.5~229.7 ppm (area exposure level close to the degreasing machine) with TWA. Case 3. A 22-yearold Vietnamese female worker developed a skin rash 30 days after starting to use TCE for degreasing. The skin rash developed into a bullous eruption and the liver function findings were abnormal. She was diagnosed with Stevens-Johnson syndrome and toxic hepatitis. Her symptoms improved and she was discharged 37 days after the onset of the first symptom. She had no previous history of taking medicine or viral infection. The work environment measured 107.2 ppm (personal exposure level) with TWA.
DISCUSSION
These three case reports and the previously reported cases indicated that the majority of people susceptible to TCE develops Stevens-Johnson syndrome after high-level TCE exposure (above the TWA occupational exposure limit of 50 ppm). Therefore, work environmental survey and improvements to the TCE degreasing process are essential to prevent high exposure. Furthermore, considering the consistency of the latency period in symptoms and the possibility of sensitization in low-level exposure, we recommend that the first specific health examination also should be conducted 1 month after workers have commenced working.

An Outbreak of Acute Beryllium Disease in a Compound Metal Alloy Factory
Hyunjoo Kim, Woo Chul Jeong, Young Koo Jee, Dae Seong Kim, Seong Kyu Kang, Sangchul Roh, Kyutag Cho, Donghyun Kim
Korean Journal of Occupational and Environmental Medicine 2008;20(1):1-8.   Published online March 31, 2008
DOI: https://doi.org/10.35371/kjoem.2008.20.1.1
AbstractAbstract PDF
OBJECTIVES
We conducted an epidemiological survey to inquire into an outbreak of acute pneumonitis after two reported cases of interstitial lung disease.
METHODS
The study subjects were 45 workers from a compound metal alloy factory. We reviewed the factory's industrial hygiene data along with the results of a special health examination, including pulmonary function tests, simple chest X-rays, and high resolution computed tomography.
RESULTS
The air concentrations of beryllium ranged from 0.42 microgram/m3 to 112.3 microgram/m3, and the mean concentration of urinary beryllium were 1.53+/-0.79 microgram/g of creatinine in the molding workers, 1.41+/- 0.50 microgram/g of creatinine in the casting workers, and 1.16+/-0.53 microgram/g of creatinine in the sorting workers. The rates for cough (p=0.054), dyspnea (p=0.030), and the use of medical services (p=0.018) were higher in the molding workers than in the non-molding workers. The incidence rate of acute interstitial lung disease was higher for the molding process (32.0%) than for the non-molding process (5.0%) (p=0.012). The time of employment for all patients was prior to December 1st, 2002.
CONCLUSIONS
Since most of the patients were molding workers, and all of the patients had worked without a ventilation system, this outbreak of acute interstitial lung disease was regarded as acute beryllium disease. Although the direct cause of the epidemic was the beryllium fumes, the fundamental cause was improper control of the work environment. Therefore, the means for preventing avoidable epidemics of occupational diseases are discussed.

Prevalence of Occupational Asthma and Exposure Level of Pharmaceutical Dust of Workers in a Pharmaceutical Company
Sung Soo Oh, Yong Hyu Choi, Eun A Kim, Young Mok Lee, Jae Kil Jang, Jang Jin Yoo, Seung Hyun Park, Soo Young Jung, Tae Kyun Kim, Kyoo Sang Kim, Seong Kyu Kang
Korean Journal of Occupational and Environmental Medicine 2006;18(2):94-102.   Published online June 30, 2006
DOI: https://doi.org/10.35371/kjoem.2006.18.2.94
AbstractAbstract PDF
OBJECTIVES
After the investigation of one worker with occupational asthma, we surveyed the prevalence of occupational asthma and the exposure level of pharmaceutical dust of 32 workers in a pharmaceutical company.
METHODS
Thirty-two of the 90 employees participated in the survey which consisted of questionnaire, blood sampling, spirometry and skin prick tests with 8 common allergens as well as 9 antibiotics and 2 enzymes. Various indices of the working environment were also measured. Subjects who had a symptom suggestive of work-related asthma or positive skin prick test were further investigated by PC20 methacholine. Nine subjects who had a PC20 result of 16 mg/ml or less (n=7) or had work-related symptoms and positive skin prick test (n=2) were referred to undergo a specific bronchial provocation test to pharmaceutical dust in an academic allergic disease center.
RESULTS
Eleven of 32 workers (34.4%) had a work-related symptom suggestive of occupational asthma. Ten (31.2%) showed positive skin prick test. 8 (25.0%) had a PC20 result of 16 mg/ml or less (indicative of significant bronchial hyperresponsiveness), and 5 (15.6%) had a positive result on the specific bronchial provocation test. Exposure levels of stuffing, input of raw materials and screening process were relatively high.
CONCLUSIONS
This survey showed that pharmaceutical workers have an increased risk of occupational asthma. Although pharmaceutical factories maintain a relatively good working environment, careful control of respiratory tract exposures, especially during stuffing, input of raw materials and screening process, is important to prevent occupational asthma. Pharmaceutical workers need to undergo regular skin prick and methacholine bronchial provocation tests, as well as asthmatic symptom survey, to ensure the early detection and prevention of occupational asthma.

Acoustic Calibration of Clinical Audiometers Used for Special Periodic Health Examination
Kyoo Sang Kim, Yong Lim Won, Soo Young Chung, Seong Kyu Kang
Korean Journal of Occupational and Environmental Medicine 2004;16(4):381-390.   Published online December 31, 2004
DOI: https://doi.org/10.35371/kjoem.2004.16.4.381
AbstractAbstract PDF
OBJECTIVES
Various problems are encountered during audiometric testing. Deviation from reference threshold levels for supra-aural earphones is often a serious problem when hearing levels are measured. This paper reports the acoustic calibration of clinical audiometers used for special periodic health examination.
METHODS
ANSI S3.6-1996 Specification for Audiometers represents our most current and best resource for information regarding audiometers. The acoustic calibration was measured in 211 clinical audiometers and compared with the ANSI S3.6-1996 reference threshold levels for supra-aural earphones.
RESULTS
Among 211 clinical audiometers, 56 (26.5%) exceeded the permitted deviation from reference threshold levels at any test frequency in ANSI S3.6-1996 for left supra-aural earphones, and 54 (25.6%) for right. An exhaustive calibration was required for 16 audiometers (7.6%) in both supra-aural earphones. The absolute difference in dB deviation from reference threshold levels by performed acoustic calibration at least annually were statistically significant at any test frequency (p<.05).
CONCLUSIONS
The results of this study strongly indicate that clinical audiometry is being conducted with pure-tone audiometers having unallowable sound pressure levels deviations for supra-aural earphones. The validity of audiometric hearing thresholds are significantly affected by these deviations from the acoustic calibration levels of audiometers. Therefore audiometer calibration need to be checked functionally daily and acoustically at least annually.

Ambient Noise Levels in the Audiometric Test Rooms Used for Special Periodic Health Examination
Kyoo Sang Kim, Yong Hyu Choi, Yong Lim Won, Seong Kyu Kang
Korean Journal of Occupational and Environmental Medicine 2004;16(3):316-328.   Published online September 30, 2004
DOI: https://doi.org/10.35371/kjoem.2004.16.3.316
AbstractAbstract PDF
OBJECTIVES
The ambient noise levels in the test rooms affect the workers's hearing threshold. The present study was designed to assess the ambient noise levels in the test rooms to determine if valid hearing tests, both pure-tone air conduction and bone-conduction, could be performed in these environments.
METHODS
In the present study, third octave band ambient noise sound pressure levels were measured in 124 audiometric test rooms used for clinical audiometry, and the results were compared with the ANSI third octave band maximum permissible ambient noise levels (MPANLs) for each test condition and frequency range.
RESULTS
The ambient noise SPLs were highest in the lower frequencies, and this decreased as the frequency increased. For the "ears covered"condition, about 24.2% of the rooms were in compliance (pass) with the MPANLs for the 125-8000 Hz, 35.5% were in compliance for the 250-8000 Hz range and 55.6% were in compliance for the 500-8000 Hz range. For the "ears not covered"condition, only about 8.1% of the rooms passed for the 125-8000 Hz, 13.7% of the rooms passed for the 250-8000 Hz range and 34.7% of the rooms passed for the 500-8000 Hz range. All 124 rooms met the OSHA MPANLs.
CONCLUSIONS
The results of this study strongly indicate that clinical audiometry is being conducted in test rooms having unacceptable or excessive ambient noise levels.

Assessment of Neurobehavioral Performance Among Rotogravure Printing Workers Exposed to Toluene
Soo Young Chung, Seong Kyu Kang, Dae seong Kim, Se Hoon Lee
Korean Journal of Occupational and Environmental Medicine 2004;16(2):115-128.   Published online June 30, 2004
DOI: https://doi.org/10.35371/kjoem.2004.16.2.115
AbstractAbstract PDF
OBJECTIVES
The aims of this study were to investigate the occupational exposure level to toluene among rotogravure printers and neurobehavioral effects among them.
METHODS
Fifty rotogravure printers and 147 controls participated in this study. Environmental and biological monitoring was performed for the investigation of toluene exposure level, and neurobehavioral performance test were performed by using the Behavioral Assessment and Research System with Korean language instructions(BARS-K).
RESULTS
The major results were as follows; 1. Geometric mean toluene concentrations in the ambient air of 5 rotogravure printing workplaces were 10.5 (GSD 5.9)~181.9 (GSD 17.7), with a grand total of 56.7 (GSD60.9) ppm. 2. The geometric mean urinary hippuric acid level for rotogravure printers of 5 workplaces were 0.31 (GSD 0.11)~5.14 (GSD 0.55), with the grand total of 1.87 (GSD 2.06) g/g creatinine. 3. There was a linear correlation between hippuric acid levels in urine and the exposed toluene in air: urine hippuric acid (g/g creatinine)=0.03 toluene (ppm) + 0.15 (r=0.899, p<0.01, n=50). 4. After adjustment for confounders, significant associations were found between toluene exposure and Digit span forwards, Digit span backwards, Tapping preferred hand, Symbol digit and Selective attention trials.
CONCLUSIONS
1. Rotogravure printers were occupationally exposed to relatively high concentration to toluene, and their neurobehavioral performances were decreased. 2. The BARS neurobehavioral testing program, which minimizes the use of text in the instructions, was very effective in overcoming the cultural barriers in neurobehavioral testing.

Analysis of Occupational Diseases Compensated with the Industrial Accident Compensation Insurance from 2001 to 2003
Yeon Soon Ahn, Seong Kyu Kang, Kwang Jong Kim
Korean Journal of Occupational and Environmental Medicine 2004;16(2):139-154.   Published online June 30, 2004
DOI: https://doi.org/10.35371/kjoem.2004.16.2.139
AbstractAbstract PDF
AIMS: The purpose of this study is to analyze the characteristics of the occupational diseases compensated with the Industrial Accident Compensation Insurance that is operated by the Korea Labor Welfare Corporation (KLWC).
METHODS
Using the KLWC database, we collected 4,240 cases of compensated occupational disease occurring between 1 January 2001 and 31 December 2003. We analyzed the characteristics (sex, age, type of occupational disease, exposure material, type of industry and occupation, etc.) of occupational diseases using the KLWC electronic data and compensated with the data of claimed cases investigated by the Korea Occupational Safety and Health Agency (KOSHA).
RESULTS
KLWC approved 4,240 cases, including 1,199 deaths (28.3%). Men accounted for 92.6% (3,925 cases) of the approved cases. The most common age group was 50-59 years of age (n=1,433, 33.8%). The majority of diseases were respiratory diseases (2,906 cases, 68.5%), occupational hearing loss (687 cases, 16.2%), infectious disease (238 cases, 5.6%), intoxication (117 cases, 2.8%), skin diseases (111 cases, 2.6%) and cancer (41 cases, 1.0%). The causal hazardous agents were dust (2,870 cases, 67.7%), physical agents (770 cases, 18.2%), biological agents (301 cases, 7.1%), chemical agents (242 cases, 5.7%), and heavy metals (51 cases, 1.2%). The major types of industry were mining and quarrying (2,708 cases, 63.9%), manufacturing (1,112 cases, 26.2%), health and social work (159 cases, 3.8%) and construction (63 cases, 1.5%). The type of occupation included craft and related trades workers (2,622 cases, 61.8%), elementary occupations (730 cases, 17.2%), senior officials and managers (327 cases, 7.7%) and plant and machine operators and assemblers (225 cases, 5.3%).
CONCLUSIONS
We were able to elucidate the kinds of occupational disease and the characteristics of workers through this study. Many compensation cases occurred among non-manufacturing and non-mining workers, especially health care workers, and there were various kinds of disease. This suggests that a management policy must be established to prevent occupational diseases occurring among workers in the above types of industry.

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
AbstractAbstract PDF
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.

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
AbstractAbstract 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.

Analysis of Work-Related Musculoskeletal Disease by Approved Korea Labor Welfare Corporation in 1999
Yeon Soon Ahn, Yong Hyu Choi, Seong Kyu Kang, Ho Keun Chung
Korean Journal of Occupational and Environmental Medicine 2002;14(2):154-168.   Published online June 30, 2002
DOI: https://doi.org/10.35371/kjoem.2002.14.2.154
AbstractAbstract PDF
OBJECTIVES
The purpose of this study was to analyze the characteristics of workrelated musculoskeletal diseases, as listed by the Korea Labor Welfare Corporation (KLWC).
METHODS
Using the database of the KLWC, we collected information from 410 approved occupational musculoskeletal disease cases, which occurred between 1 January and 31 December 1999 and were approved by 30 June in 2000. We investigated the characteristics of the disease using a mail survey and telephone interviews. The characteristics we investigated included : sex, age, disease-related working duration, process of disease occurrence, type of enterprises, etc.
RESULTS
Men accounted for 75.6 % (310 workers) of the approved cases. The most common age group was 30-39 years (n=143, 34.9 %). The mean disease-related working duration was 5.7 years, and the most commonly had a work-duration of 1-5 years (n=108, 36.0 %). The major industrial types of enterprise were manufacturing (235 workers, 57.3 %), transportation (46 workers, 11.2 %), and construction (25 workers, 6.1 %). Within the manufacturing industry, the most common was motor vehicles and trailers manufacturing. Within the group, the most common jobs were plant or machine operators and assemblers (129 workers, 36.5 %), elementary occupations (90 workers, 25.5 %), and craft and related trades workers (63 workers, 17.8 %). The majority of the diseases involved lumbar problems (232 cases, 54.7 %), neck and upper extremity diseases (183 cases, 43.2 %) and lower extremity diseases (9 cases, 2.1 %). In the cases of lumbar disease, the mean age and working duration was 36.5 years and 4.7 years, respectively. Fifty-four cases of lumbar diseases were due to repetitive work and 89 due to non-repetitive work. Bad posture at work was the most common cause for those doing repetitive work(23 cases), and lifting the most common cause of problems in the non-repetitive work cases (27).
CONCLUSIONS
We were able to elucidate the characteristics of workers with approved occupational musculoskeletal disease through this study. Many approved cases occurred in women, and workers performing repetitive work, of these herniated nucleus pulposus occurred in many workers performing simple repetitive works without serious external forces. This suggests that a prevention policy for occupational musculoskeletal disease must be established, to focusing on the above-mentioned high-risk groups.

Occupational Cancer in Korea in the 1990s
Seong Kyu Kang, Yeon Soon Ahn, Ho Keun Chung
Korean Journal of Occupational and Environmental Medicine 2001;13(4):351-359.   Published online December 31, 2001

AbstractAbstract PDF
The proportion of cancer as a cause of death in Korean has been continuously increasing. In 2000, 24 %(59,020 of 247,346) of deaths were caused by cancer. Occupational exposure would have contributed to the development of some cancers. It would have accounted for more than 2,000 cancers in a year if 4% of all cancer or 10% of lung cancer was regarded as arising from the work environment. However, occupational cancer has not been reported as much as expected. The first case of occupational cancer reported officially was mesothelioma caused by asbestos exposure at an asbestos textile industry in 1992. Following the report, many cases of occupational cancers have been reported such as lung cancer due to exposure to asbestos, chromium, exhaust gases, coke oven emissions, and silica, as well as leukemia due to exposure to benzene or other solvent and bladder cancer arising from exposure to benzidine salts. The Health Examination for retirees has been conducted since 1992 in order to detect occupational cancer early in workers who have been exposed to 11 carcinogenic substances. However, to date no occupational cancer has been detected through the Retirees' Health Examination. The Korea Labor Welfare Corporation(KLWC) has referred 108 claims for occupational cancer to the Korea Occupational Safety and Health Agency(KOSHA) between 1992 and 2000. Thirty-three cases were accepted, including 14 cases of lung cancer, eight cases of hematopoietic cancer and six cases of mesothelioma. KLWC has accepted the claim for primary lung cancer developed with pneumoconiosis as an occupational cancer, of which there were 31 cases in 1999 and 61 cases in 2000. In conclusion, special attention is required to detect occupational cancer due to their long latency period and the fact they are usually found after retirement.

AbstractAbstract PDF
OBJECTIVES
The purpose of this study is to analyze the characteristics of occupational diseases listed by Korea Labor Welfare Corporation(KLWC).
METHODS
Using the database of the KLWC, we collected 575 approved occupational disease cases occurring between 1 January and 31 December 1999 and approved by the thirtieth June in 2000. We investigated the characteristics(sex, age, occupational history, kinds of occupational disease, exposure material, type of enterprises, etc.) of occupational disease using a mail survey and telephone interviews.
RESULTS
Men accounted for 88.9 %(511 workers) of the approved cases. 56 cases(9.7%) died of occupational disease. The most common age group was 50~59 years of age(n=217, 37.7 %). The proportion of workers with grater than ten years disease related working condition exposure were 195(49.0 %). The majority of diseases were respiratory problems(211 workers, 22.4 %), occupational hearing loss(149 workers, 25.9 %), infectious disease(69 workers, 12.0 %), intoxication(60 workers, 10.4 %), skin disease(29 workers, 5.0 %) and cancer(17 workers, 3.0 %). The causal hazardous agents were dusts(209 cases, 36.3 %), physical agents(157 cases, 27.3 %), chemical agents(89 cases, 16.3 %), biological agents(82 cases, 14.3 %) and workrelated agents(34 cases, 5.9 %). The major types of enterprise were manufacturing(262 workers, 45.6 %), mining and quarrying(174 workers, 30.3 %), public administration(42 workers, 7.3 %) and the health care industry(28 workers, 4.9 %). The kinds of job included craft and related trades workers(285 workers, 49.6 %), plant or machine operators and assemblers(139 workers, 24.2 %), elementary occupations(72 workers, 12.5 %) and professionals(28 workers, 4.9 %).
CONCLUSIONS
We were able to elucidate the kinds of occupational disease and the characteristics of workers through this study. Many approved cases occurred among nonmanufacturing and non-mining workers and the kinds of disease were varied. This suggests that management policy must be established to prevent occupational disease occurring among workers in the above type of industries.

AbstractAbstract PDF
OBJECTIVES
Pneumoconisis and noise-induced hearing loss(NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardiocerebrovascular accident(CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA).
METHODS
The local office of the Korea Labor Welfare Corporation(KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999.
RESULTS
Male was 80. 7 % of the requested cases. Their mean age was 42 years old and 75. 5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50. 7 %. The majority of requested cases were respiratory diseases(22.4 %), cancers(18.5 %), Neuropsychiatric problems (14. 5 %), and musculoskeletal problems (13. 5 %). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73. 6 % of them were caused by chemical agents, especially 28. 5 % were by organic solvents. 67 % of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country.
CONCLUSIONS
A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

AbstractAbstract PDF
OBJECTIVE: The accuracy of analytical results of blood and urine heavy metals came out to the main issue on occupational health from late eighties. The discrepancy of the results for same samples from different laboratories made the diagnosis for occupational diseases be unreliable. Therefore, a quality control program for analysis of samples taken from workplace had been introduced in Korea since 1992. This study aims to show the quality control program f'or analysis of blood and urine samples and its proficient rates from 1992 to 1999 and to know how they have been being used in occupational health.
METHODS
The quality control program runs twice a year with mandatory items of blood lead and urine hippuvic acid and voluntary items of blood cadmium and manganese and urine mandellic acid and methyl hippuric acid. Participant laboratories are receiving three levels for each items and two out of three samples have to be qualified for being a proficient laboratory for the item. The acceptable range of blood lead and urine hippuric acid is +/-15% and that of the others is within 3 SD(standard deviation) from the reference values.
RESULTS
The proficient rates of blood lead and urine hippuric acid was 89%, 90%, repectively, however those of the other voluntary items have been from 51% to 62%. The proficient rates of urine mercury and urine N-methylformamide(NMF), which are introduced since 1999, were very poor. Urine hippuric acid and blood lead were analyzed frequently for the purpose of biological monitoring conducting by special health examination organizations. Urine and blood manganese and urine metabolites of trichloroethylene, urine phenol, methylhippuric acid and cadmium were followed.
CONCLUSIONS
In conclusion, the quality control program for biological monitoring has dramatically improve the ability of analysing blood and urine samples and eventually contributes to diagnose occupational diseases and to prevent occupational poisoning. However, some biological monitoring data, such as urine manganese, mercury and NMF, have been still reported from laboratories that were not accepted as a proficient laboratory.

AbstractAbstract PDF
OBJECTIVES
The study was carried out to evaluate the work-relatedness and the occupational distribution in 147 carpal tunnel syndrome(CTS) cases diagnosed at a university hospital from May 1996 to May 1998.
METHODS
We obtained the information on disease appearance, occupational history including job content and other life style by medical records and telephone interviews.
RESULTS
Of the 147 patients with carpal tunnel syndrome, 51 patients(34.7 %) were shown to be work-related. Work-related CTS were most frequent in elementary workers (21 case, 41.2%). The other eases were 15(29.4%) workers in service and shop and market sales, 9(17.6%) workers in craft and related traders, 4(7.8%) workers in skilled agriculture and fishery. Only two workers had claimed to the Industrial Accident Compensation Insurance, but no one has been admitted as an occupational CTS yet.
CONCLUSIONS
It is suggested that arrangements of surveillance system for adequate control of occupational CTD is neccessity.

AbstractAbstract PDF
Bronchial Asthma could be developed by occupational origin. 4-16% of bronchial asthmas are known to be related to occupational exposure. However, occupational asthma has not been reported from the periodic occupational health examination, but reported through case report from clinicians. The authors analysed hospital records to find out work-related bronchial asthma and their occupational characteristics at a university hospital in Jnchon. All records which were confirmed as bronchial asthma in adult by an allergist from June, 1996 to May, 1998 were selected. Through record reviewing, any suspected work related asthma was selected and the interview was done by phone or at the out-patient clinic. The possible cases were confirmed by additional tests including specific bronchial provocation test. Sixteen(3. 9%) out of 411 bronchial asthma were confirmed as work-related asthma. Eight cases out of 16 worked at furniture industry, three worked at dye manufacturing and two worked at musical instrument manufacturing industry. Others worked at farm and machinary industry. The confirmed asthmogen were toluene diisocyante(8), reactive dye(3), and grain dust(1). None of the cases was detected as work-related asthma in the periodic health examination. Twelve out of sixteen occupational asthma patients discontinued their work. The results suggested that many patients with occupational asthma were not reported and the periodic health examination was not an effective system for detecting the workrelated asthma. Thus, setting up the surveillance system involving allergist or pulmonologist would be important to detect and prevent occupational asthma.

Young Mann Baak, Yong Hyu Choi, Seong Kyu Kang, Ji Hong Kim, Kyoung Ah Kim, Young Lim, Joung Wook Lee
Korean Journal of Occupational and Environmental Medicine 1999;11(2):287-292.   Published online June 30, 1999
DOI: https://doi.org/10.35371/kjoem.1999.11.2.287
AbstractAbstract PDF
Aplastic anemia is characterized by pancytopenia with hypocellular bone marrow. Fifty percent of the cases are idiopathic and the rest are caused by various agents including drugs, chemicals, radiation and viruses. It is difficult to link specific etiologic agents, especially chemicals to the development of aplastic anemia because multiple or unknown exposures may be involved in. Benzene, a common industrial chemical and a component of gasoline, may lead progressively to pancytopenia, aplastic anemia and leukemia when exposed. A petrochemical worker with aplastic anemia was referred to our hospital to evaluate a relationship between the job history and the disease. He worked in the petrochemical plant for .21 years and was exposed to low-level benzene. There was not any other etiologic agent except benzene and this is the case report of aplastic anemia which possibly due to benzene exposure.

DOI: https://doi.org/10.35371/kjoem.1999.11.1.106
AbstractAbstract PDF
This study was conducted to examine the excretion rate of dimethylformamide (DMF) from the workers exposed to DMF. The study was done at two synthetic leather factories located in Kyeonggi-do from the period of May 2 to 30, 1996. N-methyl- formamide (NMF) concentrations in urine were measured and compared by the three exposure level of DMF in air. The mean concentration of the Low (dry and winder part). Moderate (rinsing part) and High (mixing and coating part) exposure group were 3.99+/-3.54. 10.19 +/-5.69 and 32.10+/-7.87 mg/m3 during workshift of 8 hours, respectively. The mean concentration of urinary N-methylforinamide (NMF) were 2.13+/-2.58, 11.16+/-4.98 and 26.24 +/-7.35 mg/g creatinine, respectively. The concentration of NMIF in urine could reach to maximum in 3 hours and was reduced nearly to zero in about 18 hours after exposure to DMF.

AbstractAbstract PDF
Authors report a first Korean case of polyneuropathy in an acrylamide producing factory together with an environmental and epidemiologic survey for the ten workers of the same workplace and 46 workers in the production and manufacturing acrylamide in Ulsan, Korea. The case is 30 years old man who worked in the prcduction of the acrylamide for two years. In August, 1997, he had a weakness of the lower extremity with loss of body weight of 15 Kg which progressed to paresthesia of the limbs, the loss of vibration sense, difficulty in walking, speech disturbance, dysuria, constipation, difficulty in erection and swallowing difficulty. Neurologic examination showed a complete loss of vibration and position sense, and loss of deep tendon reflex in all the limbs. There was a contact dermatitis-like skin lesion on the feet. Electrodiagnostic test showed a generalized polyneuropathy of moderate degree involving motor and sensory component of peripheral and cranial nerves. After 8 months' cessation from exposure and supportive care, his symptoms were completely resolved, but abnormality in electrodiagnostic test and vibrotactile perception threshold still persisted, although much improved than before. There were 11 workers in the same workplace of the case, producing acrylamide by microorganism as a catalyst. Environmental monitoring of the workplace revealed air-borne concentration of the acrylamide to be from 0.05 to 0.23 mg/m(3) by personal sampling and from 7.65 to 11.65 mg/m(3) by area sampling during filter exchanging process, which far exceeds TLV-TWA of 0.03 mg/m(3). However acrylamide was not detected from the plasma of the workers. Symptom questionnaire showed a markedly higher complain of neurologic symptoms, compared to the workers of the other acrylamide producing companies. Electrodiagnostic test showed a several workers are in the lower normal range without definite abnormality. Vibrotactile perception threshold by Vibratron II showed a significantly increased threshold in the workers of the same workplace compared to the other acrylamide workers and significantly decreased test score of color vision compared to normal controls. After improvement of the production process and strict wearing of the protective device, most workers reported the improvement of clinical symptoms, but vibrotactile perception threshold was not improved. These result suggests the need for the effective environmental monitoring together with a periodic biological monitoring. Development of effective screening test is urgently needed to control and assess the skin absorption of acrylamide.

AbstractAbstract PDF
Six cases of nasal septum perforation were found among welders during periodic physical checkup in 1997. Considering the size, shape and margin, the perforations were assumed to have been occurred several years before of which the diameter were 8~15 mm. To investigate the cause of perforation, we reviewed the past history of preemployment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt, and analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we presupposed that the nasal septum perforations of welders were due to chronic exposure to low level hexavalent chromium and/or nickel, and report these cases with literatures review.

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
AbstractAbstract 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.

AbstractAbstract 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.

AbstractAbstract PDF
Twenty-four factories registered at the Ministry of Labor as factories using or producing cadmium in 1991 were investigated to know the present state of occupational exposure to cadmium in 1992. Nine factories among 24 stopped using or changed to other substances and 1 factory didn't produce any more, but delivered it to other factories through imports. Therefore, only 14 factories were producing or using cadmium. But, alloying materials were uspplied to about 20 and more factories, however, they couldn't be investigated because of limited information. Three factories had less than 50 workers were 3, 6 had 50-300 and 5 had more than 300. About 167 workers were exposed to cadmium. According to the classification by process, there were 4 alloy processes, 2 refinary, 2 elctroplating, 2 dry cell making, 1 industrial battery and 1 copper refinary. 8 factories used metal cadmium, 3 cadmium oxide, 2 cadmium sulfide, and 1 cadmium hyroxide. One factory was importing cadmium stearates only and supplying them to the PVC making factories. The amount of metal cadmium producing in 2 refinary factories was about 50-65 ton per month. The other cadmium compounds were imported. According to exposure level of cadmium in air of the 10 factories examined, each factory could be divided into high, moderate and low exposure groups. 1 battery recycling factory and 3 alloy factories were in the high exposure group and their mean air concentrations were 0.06679, 0.05481, 0.02492, and 0.003mg/m3, respectively. Refinary and industrial battery making factories were in the middle exposure group and their mean air concentrations were 0.00773 and 0.00613 mg/m3, respectively. Finally, low exposure group were copper smelting, dry cell case making, duplicator drum making and electroplating factory and their mean air concentrations were 0.00096, 0.00071, 0.00057 and 0.00054 mg/m3 respectively.

AbstractAbstract PDF
Trichloroethylene (TRI) is one of the most widely used organic solvent in many industries. It is used a degreasing agent, extract and dillution solvents. TRI is metabolized by liver microsomal cytochrome P4SO to reactive intermediates, which are considered responsible for its hepatotoxicity. Cytochrome P450 is a key enzyme in the first step of TRI metabolism resulting in chloral hydrate (CH) formation, which is a rate-limiting step in TRI metabolism. This study was perfomed to find out the change of hepatic cytochrome P450 levels and of electron transport system for P-450 dependent reaction. Intraperitoneal injections of TRI were done to the male Sprague Dawley rats(mean body wights,170+/-10g) in corn oil at the dosage of 150,300,600 mg/kg for 2 days. The results of experiments are following : 1. The contents of microsomal protein, cytochrome P450 and b(5) are tended to be decreased with increasing amount of TRI, but not significantly (p>0.05) . 2. The activity of NADPH-cytochrome P450 reductase is slowly decreased by increasing amount of TRI, but not slgnificantly (p>0.05) . On the other hand, the activity of NADH-b(5) reductase is increased with increasing amount of TRI (p<0.05) 3. The activity of 7-ethoxyresolufin 0-deethylase did not show any critical changes (P>0.05) . This result suggests that the inductive pattern of TRI may not be related to P 450IAl and P450IIB.

AbstractAbstract PDF
The concentration of styrene in air and in blood and mandelic acid in urine were checked for the 60 workers with normal liver function, exposed to styrene. Styrene in air were sampled with personal air sampler at least 4 hours and analyzed by gas chromatography. Blood and spot urine were collected at the end of shift with a vacuum tube and a plyethylene bottle and analyzed by has chromatography and high performance liquid chromatography. Means of air and blood styrene and urine mandelic acid were 8.16 ppm (geometric mean), 0.199 mg/L, and 0.519 g/g creatinine, respectively. The concentration of styrene in air and mandelic acid in urine were high in the FRP factories and low in polymerization factory. Styrene in blood showed large difference by the working process. Styrene in air showed a good correlation with mandelic acid in urine(r=0.6369) and styrene in blood(r=0.6371). The mandelic acid in urine and styrene in blood corresponded to exposure of 50 ppm styrene were 0.890 g/g creatinine and 0.434 mg/L. However, hippuric acid in urine did not show any correlation with styrene in air. Urine mandelic acid excretion expected ratio showed a tendency to decrease according to obesity index and to increase with alcohol consumption.
