The Prevalence of Work Related Sickness Absences According to the Second Korean Working Condition Survey: Ki Hun Hong, Dae Seong Kim, Oh Jun Kwon, Eun A Kim; Korean Journal of Occupational and Environmental Medicine 2011;23(4):428-438. Published online December 31, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.4.428

OBJECTIVES
Worker's health is an important index used to evaluate working conditions and to prioritize prevention policies. However, this index has never before been calculated in Korea. The purpose of this study was to calculate the prevalence of health problems caused by work related sickness absences using the second Korean Working Condition Survey (KWCS) conducted in 2010.
METHODS
The second KWCS was conducted from June to October 2010 as a household survey for employed workers. The work related sickness absence rate was estimated using gender, age, business size, occupational status, level of education, and level of income. A logistic regression was performed in order to evaluate the relationship of the work related sickness absence with general characteristics and work-related conditions.
RESULTS
The rate of work related sickness absence was 1.8(+/-0.2)% for all workers, with 6.0(+/-0.3)% of it being in agriculture, forestry, and fishing, and 2.2(+/-0.5)% in manufacturing. Musculoskeletal disorders (MSD) were the most common work related disorder [1.01(+/-0.12)%], followed by psychiatric disorders [0.18(+/-0.05)%], and respiratory disorders [0.14(+/-0.04)%]. The highest odds ratio (OR) for the work related sickness absence rate was in self-employed workers with employees (OR=2.23, 95%CI=1.05~4.74).
CONCLUSIONS
The work related sickness absence rate for all workers, both self-employed and employed, including agriculture, forestry and fishing workers, and wholesale and retail trade workers was 1.8(+/-0.2)%. Because the KWCS was based on a self-reported questionnaire survey, this figure might be overestimated. In addition, it might omit chronic occupational disease and death cases.

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

Abstract 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.

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

Abstract 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.

Assessment of Neurobehavioral Performance among Welders Exposed to Manganese: Nak Jung Sung, Joon Sakong, Jong Hak Chung, Dae Seong Kim, Joong Jung Lee, Jong Tae Park; Korean Journal of Occupational and Environmental Medicine 2000;12(3):327-337. Published online September 30, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.3.327

Abstract PDF

OBJECTIVES
A cross sectional study was carried out in the welders exposed to manganese and control group. The aim of this study was to assess the adverse effects of manganese on central nervous system of welders.
METHODS
The study group consisted of 49 welders and the reference group, 49 workers matched with welders for age and educational level in automobile manufacturing company. Concentration of manganese in welding hume, in blood, and cumulative exposure index(CEI) were determined for each subject. For each group, computerized neurobehavioral test including Simple Reaction Time, Digit Symbol, Digit Span, and Finger Tapping Speed of Swedish Performance Evaluation System were applied.
RESULTS
Exposure level of manganese in welders were very low(mean CEI 0.069). Welders exposed to manganese had slower response speed, slower motor steadiness, and shorter memory span than control group. But these differences were not statistically significant. The performance of Finger Tapping Speed tended to lower as environmental and biological exposure index got higher. Other neurobehavioral tests were found to have a little association with the exposure indices.
CONCLUSIONS
There was no significant difference of neurobehavioral performance between welders and control group. This study indicates that Finger Tapping Speed measuring motor steadiness might be a one of useful tests for early detection of adverse effects of welding on central nervous system.

Analysis of Claimed Cases as an Occupational Disease at Korea Occupational Safety and Health Agency from 1992 to 1999: Seong Kyu Kang, Kyoo Sang Kim, Yangho Kim, Jung Keun Choi, Yeon Soon Ahn, Yeong Woo Jin, Byong Soon Choi, Jeong Sun Yang, Euna Kim, Chang Ho Chae, Yong Hue Choi, Dae Seong Kim, Jung Sun Park, Ho Keun Chung; Korean Journal of Occupational and Environmental Medicine 2000;12(2):292-301. Published online June 30, 2000; DOI: https://doi.org/10.35371/kjoem.2000.12.2.292

Abstract 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.

A Study on Thyroid Function among Male Workers Occupationally Exposed to Inorganic Lead: Hyeong Su Kim, Yun Cheol Park, Jae Wook Choi, Woo Whan Rho, Dae Seong Kim, Jong Tae Park; Korean Journal of Occupational and Environmental Medicine 1999;11(2):153-160. Published online June 30, 1999; DOI: https://doi.org/10.35371/kjoem.1999.11.2.153

Abstract PDF

This study was performed to evaluate the relationship between biological markers of lead exposure and thyroid functions among male workers occupationally exposed to inorganic lead. 30 male workers exposed to inorganic lead at smelting and battery factories were investigated, and 30 male control workers who were not exposed to inorganic lead occupationally were chosen for this study. The data were obtained using direct interview and assessment of biological markers of lead exposure and thyroid indices. As biological markers for lead exposure, blood ZPP. blood lead, urine lead and hemoglobin were measured. As thyroid indices. TSH and FT4were determined. The results of the study were summarized as follows 1. Levels of ZPP, blood lead, and urine lead were significantly higher in lead-exposed group than in nonexposed control group(p<0.01 all). Hemoglobin level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 2. Study subjects had normal values of TSH and FT4 But TSH level was insignificantly lower in lead-exposed group than in nonexposed control group(p=0.11) and FT4 level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 3. As the result of simple regression analysis in lead-exposed group. FT4 level was negatively correlated with the amount of smoke, blood ZPP, and blood lead(p < 0.05 all). 4. In lead-exposed group, FT4 was used as a independent variable and age, the amount of smoke, blood ZPP, and blood lead were entered as a dependent variables in the model. As the result of multiple regression analysis with stepwise selection method, the amount of smoke and blood ZPP were negative predictors of FT4(p=0. 04, p=0.09, respectively). In conclusion, levels of TSH and FT4were lower in lead-exposed group than in nonexposed control group. In lead-exposed group, FT4 level was negatively correlated with amount of smoke, blood ZPP, and blood lead in simple regression analysis. To clarify this relation, further research between lead exposure and thyroid function may be required for worker with long-term lead exposure or high lead exposure.

Sister Chromatid Exchanges in Workers Occupationally Exposed to Ethylene Oxide: Soung Hoon Chang, Won Jin Lee, Cheong Sik Kim, Cheong Hyun Hwang, Jong Tae Park, Dae Seong Kim, Young Whan Kim; Korean Journal of Occupational and Environmental Medicine 1998;10(4):428-437. Published online December 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.4.428

Abstract PDF

Operators of hospital sterilizers who use ethylene oxide (EtO) were studied to determine the exposure of EtO level and the frequency of sister chromatid exchanges (SCEs) from June 12 to July 20, 1997. To evaluate SCEs in the peripheral blood cells, we selected 22 workers at the central supply room of 4 university hospitals and 22 unexposed workers at the same hospitals according to match sex, age, and smoking habit and also did questionnaires. The mean air concentrations (8-hr TWA) of EtO at 4 university hospitals were less than 1 ppm. The SCE frequencies in exposed workers to EtO and controls were normally distributed. The SCE frequencies in exposed workers to EtO and controls were 6.42+/-.63, 5.86+/-.69, respectively and their differences were statistically significant (p=0.0093). But there were no statistically significant differences in smoking, alcohol intake, coffee drinking. Especially smokers who exposed to EtO were increased SCE statistically significant than the exposed group who did not smoke.
