In Seok Kim, Sang Chul Ryu, Yong Hyun Kim, Young Jun Kwon
Korean Journal of Occupational and Environmental Medicine 2012;24(2):158-166.   Published online June 30, 2012
DOI: https://doi.org/10.35371/kjoem.2012.24.2.158
AbstractAbstract PDF
OBJECTIVES
This study was performed to analyze the factors that have been meaningful in recognizing cerebrovascular and cardiovascular diseases in manufacturing sector workers as work-related diseases, since amendment of Industrial Accident Compensation Insurance Act on July 1st, 2008, and provide information to establish an objective standard.
METHODS
We examined 359 claims of cerebrovascular and cardiovascular diseases which were presented as occupational diseases from January 1st, to December 31th, 2010, collecting Industrial Accident Compensation data from the six Provincial Committees for work-related disease decision. We analyzed the approval rate and odds ratio of the general characteristics, past medical history and work-related information, by using univariate logistic regression. In addition, we confirmed the factors that have effects on when approving work-related diseases by using multivariate logistic regression.
RESULTS
Overall, 92 claims out of the 359 claims were recognized as worked-related diseases with an approval rate of 25.6%. Because of accidental situations such as altercation, cold environments, fire etc., only 12 cases were approved. In addition, due to short-term overwork such as outdoor work in cold environments, only 18 cases were approved. Sixty-two cases were approved for chronic overwork. On chronic overwork, the approval rate was not significantly different in univariate logistic regression in gender, age, claimed disease, survival or death, smoker or non-smoker, or associated disease. However, factory size and, average working time for last one week and average working time for last four weeks were significantly. In the multivariate logistic regression analyzed, adjusted for age and sex, we found that the factors in approving cerebrovascular and cardiovascular disease as work-related disease were average working time for the last four weeks and factory size.
CONCLUSION
We concluded that there has been a great deal of subjective judgements when approving cerebrovascular and cardiovascular diseases to be occupational diseases. Therefore, objective criteria should be established, especially with regard to the approval of work-related cerebrovascular and cardiovascular diseases and working hours.

A Case of Amyotrophic Lateral Sclerosis in an Equipment Maintenance Worker Exposed to Lead
In Ki Yoon, Hyoung Jun Lim, Young Su Ju, Se Jin An, Young Jun Kwon
Korean Journal of Occupational and Environmental Medicine 2012;24(2):195-205.   Published online June 30, 2012
DOI: https://doi.org/10.35371/kjoem.2012.24.2.195
AbstractAbstract PDF
OBJECTIVES
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease involving the upper and lower motor neuron of the brain and spinal cord, leading ultimately to death due to respiratory failure in most cases. The etiology of ALS is currently unknown, but several studies show that lead exposure might be one of the potential environmental causes of ALS. In this perspective, we introduce a case involving an ALS patient exposed to lead while maintaining mechanical equipment in a waste treatment plant.
METHODS
The patient was interviewed and his medical records were investigated to confirm the final diagnosis of ALS. The results of his health examination and working environment measurement were reviewed in order to evaluate the relation of his work with ALS. We also performed an analysis of lead concentration from samples taken from his workplace when we visited the plant to survey the work environment.
RESULTS
Based on the patient's clinical information, work environment, relatively high level of blood lead concentration, and several studies proposing the occupational relationship between lead and ALS, his ALS may possibly have been caused by lead exposure at his workplace.
CONCLUSIONS
Given the recent situation where the causal association between lead exposure and ALS is still unclear, this case report could be used as a basis to support the relevance of lead exposure with ALS, and to help improve the health and work environment of other workers who are likely to be exposed to lead.

Sang Chul Ryu, In Suk Kim, Jong Heon Lee, Jong Uk Won, Tae Won Jang, Young Jun Kwon
Korean Journal of Occupational and Environmental Medicine 2011;23(4):379-386.   Published online December 31, 2011
DOI: https://doi.org/10.35371/kjoem.2011.23.4.379
AbstractAbstract PDF
OBJECTIVES
This study was conducted to analyze the factors that affected the decision of claims for cerebrovascular disorders and cardiovascular diseases in chronically overworked workers, that submitted their claims after the reformation of approval standards in the Industrial Accident Compensation Insurance Act on 1 July 2008.
METHODS
Of 2909 cases, who claimed between January 1. and December 31. 2009, 1046 cases were selected based on their worker's compensation record and investigated following 6 provincial committees for work-related diseases. The approval rate and odds ratio were analyzed with respect to the general characteristics, past medical history and work-related information using a logistical regression and Student t-test.
RESULTS
Of the 1046 selected cases, the approval rate was 18.5%(194 cases). In the multivariate logistical regression analysis, the factors for approving cerebrovascular disorders and cardiovascular diseases as work-related diseases were found to be the average working time over the last 1 week, occupational category, gender, age, death or survival, the presence of an associated disease, claimed province, and smoking.
CONCLUSION
Factors for approving claims of cerebrovascular disorders and cardiovascular diseases as work-related diseases were the average working time over last 1 week, gender, age, death or survival, claimed disease, presence of associated disease, claimed province, smoking.

The Effect of Socio-Economic Factors on Occupational Injuries in Korea: A Time Series Analysis
Ye Won Bang, Hyoung June Im, Young Jun Kwon, Seong Sik Cho, Tae Kyung Lee, In Ki Yoon, Young Su Ju
Korean Journal of Occupational and Environmental Medicine 2011;23(4):397-406.   Published online December 31, 2011
DOI: https://doi.org/10.35371/kjoem.2011.23.4.397
AbstractAbstract PDF
OBJECTIVES
We performed a time series analysis in order to identify the relationship between the occupational injury rate and socio-economic factors, and through this predict the occupational injury occurrence rate.
METHODS
We reviewed 168 sets of monthly data. For the statistical analysis, we used the economic index data provided by Statics Korea and the occupational injury index provided by the Workers' Compensation & Welfare Service gathered from 1994 to 2007. We performed a correlation analysis to find relationship between the occupation injury rate and economic factors. Using the correlation analysis result, we used time series analysis for the data in order to find out the association between occupational injuries and socio-economic indicators. We performed time series analysis to find out association occupation injury rate with socio-economic factors. In addition we ran a prediction occupational injury rate for 2008 and compared the result to the actual value.
RESULTS
The factors associated with occupational injuries were the daily worker index (b=0.394, p<0.0001), the mechanical index (b=-0.023, p=0.0043), the manufacturing operation index (b=0.152, p<0.0001), the workers compensation coverage expansion (b=1.189, p=0.015), the IMF index (b=-2.05, p<0.0001), and the after IMF index (b=-1.565, p=0.01). The daily worker index, manufacturing operation index, and workers compensation coverage expansion had an effect that increased the occupational injury rate. Conversely, the mechanical index and IMF variable tended to decrease the occupational injury rate.
CONCLUSIONS
This study suggests that the daily worker index, manufacturing operation index, workers compensation coverage expansion, and IMF variables are related factors in regards to occupational injury.

The Relationship between Job Stress and hsCRP
Jong Heon Lee, Tae Won Chang, Young Jun Kwon, Yong Kyu Kim, Sang Chul Ryu, In Suk Kim
Korean Journal of Occupational and Environmental Medicine 2011;23(3):261-269.   Published online September 30, 2011
DOI: https://doi.org/10.35371/kjoem.2011.23.3.261
AbstractAbstract PDF
OBJECTIVES
We wanted to investigate the relationship between job stress and high-sensitivity C-reactive proteins (hsCRP) with a view to using them as a predictor of future cardiovascular events.
METHODS
The study subjects were 155 male bank workers. A structured, self-assesment questionnaire was used to analyze the sociodemographic characteristics and job stress of the participants. Seven levels of job stress, as described in the Korean Occupational Stress Scale-Short Form (KOSS-SF), were used to categorized the participants. We included tests for blood pressure, fasting blood sugar, blood lipid level (total cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides), and hsCRP in our analysis. Multiple logistic regression modeling was used to determine an association between job stress and cardiovascular risk factors including hsCRP.
RESULTS
In the multiple logistic regression analyses adjusted for general and job characteristics and cardiovascular risk factors, interpersonal conflict (adjusted OR 1.69, 95% CI=1.11~2.57), job insecurity (adjusted OR 1.94, 95% CI=1.24~3.03) and, occupational climate (adjusted OR 1.89, 95% CI=1.19~3.01) were associated with hsCRP.
CONCLUSION
This study suggests that job stress is associated with hsCRP which is a predictor of future cardiovascular events.

A Case of Kienbock's Disease from Repetitive Contact Stress
Chul Ju Kim, Young Su Ju, Hyoung June Im, Yae Won Bang, Young Jun Kwon
Korean Journal of Occupational and Environmental Medicine 2011;23(3):343-349.   Published online September 30, 2011
DOI: https://doi.org/10.35371/kjoem.2011.23.3.343
AbstractAbstract PDF
OBJECTIVES
Kienbock's disease, which is characterized by osteonecrosis of the lunate bone, causes progressive chronic pain and dysfunction of the hand and wrist. Even though occurrence of the disease was reported approximately 100 years ago and it is suspected to be work-related to some degree, the etiology has not been clearly discribed and the disease has rarely been considered as an occupation-related disease. As such, we submit this case as the first report of Kienbock's disease in Korea, with clinical findings, x-ray, MRI (magnetic resonance imaging) and strain index results along with a literature review.
METHODS
The patient was carefully interviewed and her medical records were properly reviewed by the authors with her consent. The authors also visited her factory work site to inspect and videotape the working environment and to conduct an ergonomic evaluation with a strain index.
RESULTS
Excessively repeated contact stress was found to be concentrated on her right hand and the environment was discovered to be hazardous from an ergonomic standpoint. The literature review revealed that heavy loads on the hand might be related to the cause or deterioration associated with Kienbock's disease. ; therefore, it is very likely that her disease is related to her work.
CONCLUSIONS
There is much evidence to suggest that heavy workloads involving hand and wrist intensive tasks may cause and worsen Kienbock's disease. However, to date epidemiologic studies clarifying the etiology of the disease have not been sufficiently reported. Therefore, further research focusing on the etiology and prevention of the disease are required. In addition, practical guidelines for hand and wrist intensive tasks are needed to prevent disease development and worsening.

Worker's Compensation Claims and Approval Status for Occupational Cancers in Korea from 2000 to 2009
Won Cheol Lee, Dong Il Kim, Young Jun Kwon, Hyoung Ryoul Kim, In Ah Kim, Jae Hong Ryoo, Soo Geun Kim
Korean Journal of Occupational and Environmental Medicine 2011;23(2):112-121.   Published online June 30, 2011
DOI: https://doi.org/10.35371/kjoem.2011.23.2.112
AbstractAbstract PDF
OBJECTIVES
The purpose of this study is to analyze the characteristics of the occupational cancer claims compensated by the Industrial Accident Compensation Insurance that is operated by the Korea Workers' Compensation and Welfare Service (COMWEL).
METHODS
Using the COMWEL electronic database, we collected 1,933 claims for occupational cancer based on the worker's compensation records in the COMWEL from 1 January 2000 to 31 December 2009. We analyzed the characteristics of the claims.
RESULTS
The average number of claims per year for occupational cancer was 193 and the approval rate was 13.1% from 2000 to 2009. Men accounted for 93.7% of the approved cases and had a higher approval rate. Approval rates increased with age. Among claims for occupational cancer, the most common was digestive cancer. On the other hand, the highest approval rate was for mesothelioma claims, followed by respiratory cancer, lymphoid or hematopoietic cancer. By industry, claims were most common in manufacturing, but the approval rate was highest in mining and quarrying. By occupation, claims most commonly came from legislators, senior officials & managers, but the approval rate was highest for craft & related trades workers. The average of tenure period was 15.5 years for approved cases, but 10.3 years for non-approved cases, respectively.
CONCLUSIONS
We analyzed the characteristics of the occupational cancer claims which were compensated for the last 10 years accrording to the approved results. For the purpose of long-term understanding and management of worker's compensation status for occupational cancer, we should gather accurate information of the carcinogenic factors involved in order to achieve the systematic improvement that is needed.

Jung Wook Lim, Young Jun Kwon, Tae Won Jang, Jong Heon Lee, In Seok Kim, Sang Cheol Ryu, Jae Hoon Roh, Jong Uk Won, Bong Suk Cha, Chul Ho Lee
Korean Journal of Occupational and Environmental Medicine 2010;22(4):307-315.   Published online December 31, 2010
DOI: https://doi.org/10.35371/kjoem.2010.22.4.307
AbstractAbstract PDF
OBJECTIVES
This study was conducted to identify the effect of a stretching exercise on myofascial pain syndrome patients that work in small and medium-sized industry.
METHODS
Questionnaires surveys including general characteristics, work-related characteristics, and musculoskeletal symptoms on neck and shoulder area was administered to 393 subjects who worked in small and medium sized industries. Symptomatic workers were examined to identify whether they had myofascial pain syndrome (MPS). Of the 393 subjects, 108 MPS patients performed 6 weeks stretching exercise program. Intensity of pain was estimated with visual analogue scales (VAS). All patients were interviewed to estimate their compliance to stretching exercise program.
RESULTS
Of the 393 workers, 119 workers were diagnosed with MPS of the neck and shoulder. Post-exercise VAS was significantly reduced compared to pre-exercise VAS (p<0.05). High compliance patients to stretching exercise were more effective to exercise therapy (OR 2.89, 95% CI 1.19~7.04), and overtime workers were less effective to exercise therapy (OR 0.41, 95% CI 0.17~0.95).
CONCLUSION
The Stretching exercise program was identified to be effective in MPS patients in small and medium-sized industries. It is recommended that workers with MPS in small and medium-sized industries practice a well-designed stretching exercise program, and avoid overtime work.

Influencing Factors in Approving Cerebrovascular and Cardiovascular Diseases as Occupational Disease in Seoul
Tae Kyung Lee, Soo Geun Kim, Jong Uk Won, Tae Won Jang, Seong Sik Cho, Young Su Ju, Young Jun Kwon, Hyoung June Im
Korean Journal of Occupational and Environmental Medicine 2010;22(3):262-270.   Published online September 30, 2010
DOI: https://doi.org/10.35371/kjoem.2010.22.3.262
AbstractAbstract PDF
OBJECTIVES
This study was performed to analyze the factors that affected the decision making process in approving workers' compensation claims for cerebrovascular and cardiovascular diseases cases that occurred just before refoming approval standards of Industrial Accident Compensation Insurance Act on 1 July 2008 and to provide fundamental information in preparing better standards.
METHODS
We examined 283 claims cases involving cerebrovascular and cardiovascular diseases that occurred between 1 January, 2006 and 31 December, 2007 and collected data based on the worker's compensation records from 3 Seoul Regional Centers of the Workers' Compensation & Welfare Service. We analyzed the approval rates and odds ratios according to the general characteristics, injury information, past medical histories, and work related information using chi-square or univariate logistic regression. In addition, we identified the factors affecting the approval using multivariate logistic regression.
RESULTS
Overall, 101 of the 283 cases were approved and approval rate was 35.7%. Approval rates differed significantly according to type of disease, survival, accident site, accident time, the presence of associated disease and overwork (p-value <0.05). In the multivariate logistic regression analysis with adjusted for age and sex, approval rate of death cases with associated disease was lower than cases without associated disease (OR 0.22, 95% CI 0.12~0.42). Approval rate of cases occurred in worksite was higher than others (OR 4.81, 95% CI 2.22~10.40). Cases of accepted overwork had a higher approval rate significantly than cases of not accepted (OR 28.53, 95% CI 9.74~83.52).
CONCLUSION
Factors in approving cases of cerebrovascular and cardiovascular disease as cases involving occupational disease included conditions of overwork, high rate of accidents in the workplace and the presence of associated disease. It is necessary to investigate further behaviors of work and chronic work-related stress.

Factors Related to Occupational Injuries and Health Problems for Some Female Workers in Non-standard Employment
Woo Jin Park, Hyoung June Im, Jong Uk Won, Sang Baek Koh, Young Su Ju, Jae Hoon Roh, Sang Yong Oh, Young Jun Kwon, Chang Kook Hwang, Jung Wook Lim
Korean Journal of Occupational and Environmental Medicine 2009;21(4):301-313.   Published online December 31, 2009
DOI: https://doi.org/10.35371/kjoem.2009.21.4.301
AbstractAbstract PDF
OBJECTIVES
The purpose of this study was to examine certain factors associated with occupational injuries and health problems for some female workers in non-standard employment.
METHODS
We enrolled 754 female workers that were selected from 1,040 people who had agreed to be surveyed as part of a group or company in either the Seoul and the Kyonggi area. We performed univariate logistic regression on survey data and again performed multivariate logistic regression on those variables that were statistically significant.
RESULTS
In this study, the overall incidence of occupational injury for all workers was 12.5%. The incidence rates by position were as follows: 12.9%(insurance saleswoman), 7.4%(telemarketer), 9.2%(visiting teacher), 22%(golf caddy). The most frequent complaint was lower back pain(12.8%) in insurance saleswomen, voice symptoms(37%) in telemarketers, knee and ankle symptoms(33.8%) in golf caddies, and voice symptoms(14.4%) in visiting teachers. The factors related to occupational injuries included job type, and age. The factors related to health problems were job type, psychosocial stress, accident risk, and social support. The percentage of the cases that occurred without fringe benefits including social welfare was 30.4%, and the percentage of "paid out of the person's own pocket" of ways to arrange costs of accidents was 32.5%.
CONCLUSIONS
In this study, some female workers in non-standard employment had relatively high level of occupational injuries, accompanied by various health problems. In these occupational classes, the conditions for social insurance and social welfare were poor. It is necessary to expand the application of social insurances including industrial accident compensation insurance. Regardless of job category, psychosocial stress and social support were statistically significant for many symptoms. We believe that measurement of these factors is necessary. In the future, additional studies are required with the use of objective methods for additional job categories.

The PTSD Symptom and Related Factors among the Residents after Samsung-Hebei Spirits Oil Spill
Seongsik Cho, Tae Kyung Lee, Jeong Min Kim, Ye Won Bang, Narae Hong, Hyoung June Im, Young Jun Kwon, Yong Cho, Jae Yong Moon, Young Su Ju
Korean Journal of Occupational and Environmental Medicine 2009;21(3):235-245.   Published online September 30, 2009
DOI: https://doi.org/10.35371/kjoem.2009.21.3.235
AbstractAbstract PDF
BACKGROUND
The purpose of the study was to estimate the mental health problems and other related factors in residents that experienced the Samsung-Hebei spirits oil spill by surveying PTSD symptoms.
METHOD
Trained interviewers performed direct interviews of the residents approximately 70 days after the oil spill. We investigated PTSD symptoms through PTSD Symptom Scale Interview Version (PSS-I). To determine those factors related to PTSD symptoms, the following factors were determined as part of the survey: gender, age, occupation, duration of cleanup activity, monthly income and amount of debt. Logistic regression analysis was used to analyze all factors.
RESULTS
Of the 318 residents investigated, 56.6% of the subjects had PTSD symptoms related to the spirits oil spill (about 70 days post spill). With regard to occupation, those subjects answering fishery (POR:3.05) and commerce (POR:4.24) as their occupations experienced higher PTSD symptoms than residents answering farming as their occupation. Residents who answered that they had debt over 10 million KRW (POR:2.61) were more vulnerable to PTSD symptoms compared to residents without debt; residents with acute physical symptoms were vulnerable (POR:5.11) to PTSD symptom compared to residents without acute physical symptoms. The results of multiple logistic analysis, including the cleanup activity, age, gender, occupation, acute physical symptoms and amount of debt in the model suggest that only cleanup activity increased PTSD symptoms. The subjects who had engaged in cleanup activities for longer periods of time had more PTSD symptoms and an additional dose-response relationship.
CONCLUSION
Many residents in Samsung-Hebei spirits oil spill area had PTSD symptoms. This suggests that there were serious mental health problems among the residents, who might require specific social supports and psychiatric interventions as a result of the oil spill.

Jeong Min Kim, Young Jun Kwon, Young Su Ju, Hyoung June Im, Tae Kyung Lee, Hye Ryun Kang, Do Myung Paek
Korean Journal of Occupational and Environmental Medicine 2008;20(3):245-259.   Published online September 30, 2008
DOI: https://doi.org/10.35371/kjoem.2008.20.3.245
AbstractAbstract PDF
OBJECTIVES
To determine the prevalence of baker's asthma due to flour dust in an industrial bakery in Korea.
METHODS
Of the 596 active workers, 380 were allocated to a category of either direct exposure (DE) or indirect exposure (IE) to flour dust and completed a modified ISAAC questionnaire. Of the 380 participants, 233 were screened by an occupational physician interview, a skin prick test, and an ELISA for serum-specific IgE antibodies to wheat flour extracts. Selected workers received serial monitoring of peak expiratory flow rate (PEFR), and positive PEFR respondents received a methacholine challenge test. The diagnosis of baker's asthma was confirmed by a specific inhalation challenge with wheat flour extracts.
RESULTS
The prevalence of sensitization to wheat flour and baker's asthma was 21.0% (25.9% DE, 13.3% IE) and 3.2% (5.1% DE, 1.8% IE), respectively. DE had an increased risk of sensitization to wheat flour (OR 2.15, 95% CI = 1.03~4.51). Sensitization to wheat flour and the prevalence of baker's asthma correlated significantly (PR 38.63, 95% CI = 6.14~243.22).
CONCLUSIONS
These findings indicate a considerable prevalence of baker's asthma among flourexposed workers in Korea. Future studies will be required to survey the situation in flour mill companies and seek ways to protect the health and socioeconomic position of flour industry workers.

Hwa Pyung Lee, Hyoung June Im, Young Su Ju, Young Jun Kwon, Hee Tae Kang, Jeong Min Kim, Sung Sik Cho, Tae Kyung Lee, Jongwan Yoon
Korean Journal of Occupational and Environmental Medicine 2007;19(3):204-214.   Published online September 30, 2007
DOI: https://doi.org/10.35371/kjoem.2007.19.3.204
AbstractAbstract PDF
OBJECTIVES
To evaluate the patient satisfaction and its influencing factors after medical care for workrelated injuries.
METHODS
A self-reported questionnaire was mailed to 921 workers who had experienced workers' compensation medical care. The data from 335 respondents (response rate was 36.4%) were merged and analysed with the data from the Korea Labor Welfare Corporation (KLWC) which contain other general information of the respondents.
RESULTS
Dissatisfaction with their medical care was reported by 17.3% of the respondents. Overall patient satisfaction (OPS) was highly correlated with the medical treatment process such as hospital facility, medical therapy, surgical therapy, doctor's explanation and physical therapy. However, OPS was negatively influenced by three factors: 1) unsatisfactory hospital care during waiting period before the approval of workers' compensation, 2) forced end of the hospital care by the workers' compensation, and 3) end of the hospital care with no further improvement.
CONCLUSIONS
To improve the satisfaction of patients with work-related injuries, both the practice of medical treatment and also the administrative process of workers' compensation must be reformed. These reforms are needed to improve the quality of workers' compensation medical care and prevent abnormal illness behavior such as inappropriate treatment seeking.

Predictors of Return to Work and Job Retention after Work-Related Injury or Illness
Hee Tae Kang, Hyoung June Im, Yong Kyu Kim, Young Su Ju, Hwa Pyung Lee, Jeong Min Kim, Young Jun Kwon
Korean Journal of Occupational and Environmental Medicine 2006;18(3):221-231.   Published online September 30, 2006
DOI: https://doi.org/10.35371/kjoem.2006.18.3.221
AbstractAbstract PDF
OBJECTIVES
This research was conducted to investigate workers'return to work rate after work-related injury or illness and to determine which factors could predict return to work and job retention.
METHODS
From the documents held by the six local branches of the Korea Labor Welfare Corporation(KLWP), 2,464 cases of work-related injury or illness which had telephone numbers were identified from September to December, 2003. Data about the employment status was gained from 921 occupationally injured workers through telephone questionnaire and was merged with the electronic data obtained from KLWP with included information of the workers whose worker's compensation period was ended from 2002 to 2004. Finally the data for 516 workers was analysed by logistic regression using SAS 9.0.
RESULTS
The return to work rate was 50.3% and the job retention rate was 28.3%. Decreased return to work rate was associated with old age, shorter employment duration, longer treatment duration, higher disability grade, lower average wage and manual worker. Decreased job retention rate was associated with a smaller number of employees, shorter employment duration and work in the construction industry.
CONCLUSIONS
This research highlighted the numerous occupationally injured workers who couldn't return to work and the multiple factors that were associated with the return to work or job retention. Based on this and related research, rehabilitation programs which consider the issues of return to work and job retention have to be implemented.

DOI: https://doi.org/10.35371/kjoem.2004.16.4.436
AbstractAbstract PDF
OBJECTIVES
To examine the complaint proportion and characteristics of musculoskeletal symptoms and to find risk factors of musculoskeletal symptoms among caterers for school lunch services.
METHODS
The study subjects were 385 caterers who were working for school lunch services in 71 elementary schools and 114 housewives who had visited a hospital for routine health check-up. A self-recording questionnaire was used to investigate the general characteristics, labor conditions, job stress and nature of musculoskeletal symptom. Caterers were surveyed from September to October in 2003 and the housewives during September by post. The ergonomic risk factors were examined for the caterers of an elementary school in Kyonggi Province in November, 2003.
RESULTS
The complaint proportion of self-reported positive musculoskeletal symptoms was 52.0% and that of severe musculoskeletal symptoms was 24.9%. Ergonomic assessment revealed that washing the dishes, carrying the soup containers and cleaning the sewage drain were highly risky activities in terms of repetitive and heavy weight-bearing motions. As for personal factors, the caterers having severe musculoskeletal symptoms had high psychological job demand. As for the workplace factors, the proportion of schools having severe musculoskeletal symptoms was significant higher where each caterer prepared more than 150 lunches. Among schools without school lunchroom, more schools had caterers having severe musculoskeletal symptoms. Using multilevel analysis, we found that the number of lunches to be prepared per caterer was a significant risk factor of severe musculoskeletal symptoms (O.R. 4.67).
CONCLUSIONS
This study showed that the number of lunches prepared per caterer has a significant influence on the development of musculoskeletal disorder and that caterers work in an ergonomically highly risky job environment. The study results suggest that the number of caterers be increased to decrease the number of lunches prepared per caterer and the ergonomic environment be improved.

AbstractAbstract PDF
OBJECTIVES
Although there is increasing concern about job stress, no published reports have addressed the basic characteristics of job stress (i.e. on various job stress domains), according to the Korean Standard of Job Categories. Therefore, this study was conducted to present epidemiologic data of common Korean workers on job stress domains, by using the self-reported Karasek's Job Content Questionnaire(JCQ.) METHODS: Data were gathered from many workers at various industries for 2 years, as a part of the workers'periodic health examinations, in Kyong-Gi and Kyong-Nam provinces, Korea.
RESULTS
The total respondents were 1,866, male 1,658(88.9%) and female 208(11.1%), from 117 companies. The mean age was 35.05 years old, 1,315(70.4%) were married, 1,578(84.5%) were graduated from high school or above, and 380(20.4%) were managers at workplace. The mean scores of decision latitude, psychological job demand, social support, and job insecurity were 62.56(std 8.28, median 62), 31.45(std 3.83, median 32), 22.49(std 2.58, median 23) and 6.16(std 1.90, median 6), respectively. Construction workers belonged to the high strain group, and administrative managers and computer related experts belonged to the active group.
CONCLUSIONS
To more precisely evaluate job stress according to job categories, data could be gathered from a larger sample and detailed job categories should be adopted. Such a study would form an important foundation for research into job stress in Korea.

AbstractAbstract PDF
Objectives
The prevalence of cumulative trauma disorders of upper extremities mons watch assembly workers in small-scaled industry was studied.
Methods
In 83 workers at five watch assembly factories, symptoms and psychosocial questionnaire, ergonomic Interview, physical examination were conducted.
Results
Prevalence of self-reported symptoms was 54.2% and neck 34.9%, wrist/hand 31.3%, shoulder 30.1%, elbow/arm 18.0% by anatomical site. Prevalence of cumulative trauma disorders was 45.8%. Most common disease was myofascial pain syndrome (31.3%). The other diseases were De Quervain disease (9.6%), tenosynovitis/tendinitis at wrist/hand (9.6%), bicipital tendinitis(6.0%), fat. epicondylitis(4.8%), meIn. epicondylitis(2.4%), and cervical disc disease(2.4%). As result of ergonomic interview, repetitiveness was 79(98.8%). There were no differences in the prevalence of self-reported symptoms and cumulative trauma disorders for age, sex, marital status, duration of work In the study, The significant factors of cumulative trauma disorders were occupational task and psychosocial stress in the study. The prevalence of cumulative trauma disorders in high strain group was hlgher (68.4%) than other three groups. The prevalence of self-reported symptoms and cumulative trauma disorders in assembly task was higher (70.0%, 64.0%) than other two tasks.
Conclusions
Prevalence of self-reported symptoms was 54.2%, prevalence of cumulative trauma disorders was 45.8% in watch assembly workers. In this study, factor related to self-reported symptoms was occupational task and factors relaxed to cumulative trauma disorders were occupational task and psychosocial stress. This results suggest that differences of ergonomics and environment in occupational task cause differences of prevalence of self-reported symptoms and cumulatlve trauma disorders.

AbstractAbstract PDF
A study was conducted to assess the association between musculoskeletal subjective symptoms and the MMPI(Minnesota Multiphasic Personality Inventory) profile. The study subjects were 539 female operators of telecommunication company in Seoul, and were interviewed with subjective symptom questionnaire and MMPI. Results were as follows 1. 77.5% of the study subjects complained subjective symptoms on the shoulder, 73.8% on the neck, 71.8% on the lower back, 67.5% on the arm, 67.2% on the hand, 39.8% on the elbow, respectively. According to NIOSH symptom criteria, 63% complained on the shoulder, 57.4%, 54.6% on the lower back, 53.2% on the hand, 45.9% on the arm, 29.8% on the elbow, respectively. 2. Among the MMPI clinical scales, Hs(Hypochondriasis), Hy(Hystria) and Dep (Depression) scales showed significant differences according to the numbers of subjective symptom(NIOSH criteria), VAS(Visual Analogue Scale), and the experience of sick leave (each by ANOVA, p<0.05). 3. The association between the numbers of subjective symptom site for NIOSH symptom criteria, the personal history of sick leave and the MMPI profile that has more than 70 points in anything of Hs, Dep and Hy scales was showed significantly (each by x(2)-test, p<0.05).
