This study aimed to find the prevalence and occupational risk factors for major psychiatric disorders among subway drivers in South Korea. MethodsOf all 998 current subway drivers, 995 participated in this study. The Korean version of the Composite International Diagnostic Interview (K-CIDI 2.1) was administered by trained interviewers to diagnose psychiatric disorders in all participants. The questions on socio-demographic characteristics and working conditions included some questions related to a person under train (PUT) experience and work-related problems. One-year prevalence and lifetime prevalence of major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and panic disorder were diagnosed through the interview. The standardized prevalence ratios (SPRs) of these three disorders were calculated in the sample of subway drivers using the 2011 Korean National Epidemiologic Survey data as a basis. Multiple logistic regressions were performed to determine the association between work-related factors and the prevalence of the psychiatric disorders. ResultsThe standardized prevalence ratios (SPRs) for a 1-year prevalence of MDD and PTSD among subway drivers were 1.1 (95% CI 0.7-1.7) and 5.6 (95% CI 3.1-8.8), respectively. Conflict with passengers was significantly associated with an increased risk for both MDD and PTSD in 1-year and in lifetime prevalence. Experiencing a sudden stop due to an emergency bell increased the risk of the lifetime prevalence of MDD (OR 2.61, 95% CI 1.14-6.97) and PTSD (OR 7.53, 95% CI 1.77-32.02). The risk of PTSD significantly increased among drivers who once experienced a near accident in terms of both the 1-year prevalence (OR 8.81, 95% CI 1.96-39.3) and the lifetime prevalence (OR 6.36, 95% CI 2.40-16.90). ConclusionsPTSD and panic disorder were more prevalent among subway drivers than in the general population. We found that having a conflict with passengers, a near accident, and a breakdown while driving can be risk factors for psychiatric disorders among subway drivers. Therefore, a prompt and sensitive approach should be introduced for these high risk groups within the subway company.

- OBJECTIVES
Nurses' turnover has a negative influence on the nursing staff, as well as on the hospital organization as a whole. In an effort to reduce the turnover of nurses, the conditions causing turnover intentions can be identified and managed. The research is conducted to identify the association among verbal abuse, social support, and turnover intentions for special unit nurses. METHODS A survey was conducted in 105 registered nurses who worked in the following areas at Kyonggi province hospital: operating room, intensive care unit, and anesthesia department. The questionnaires included questions in the following areas: verbal abuse by doctors, supervisors, and colleagues social supports by supervisors and colleagues and turnover intention. The survey was distributed and analyzed based on nurses' responses. RESULTS Operating room nurses had the highest turn over intentions. The verbal abuse by doctors and supervisors were highest in the operating room. Verbal abuse by supervisors had a significantly positive association with turnover intentions. Verbal abuse by doctors and by colleagues was not associated with the intention to leave. Finally, the social support by supervisors had a significant negative association with turnover intentions. Social supports by colleagues did not affect turnover intentions. CONCLUSIONS For nurses working at special units, verbal abuse and social support by supervisors had a significant association with turnover intentions. It is important for supervisors to make an effort to reduce nurses' turnover intentions by reducing verbal abuse and by increasing social support.

- OBJECTIVES
The purpose of this study was to examine the influence of self-esteem and social support on the depression stati of some clinical nurses, and propose basic data for a depression care program. METHODS Between March 31 and April 5 at 2006, a self-reporting questionnaire survey was administered to 200 nurses at a general hospital located in Gyeonggi-do. The Beck's Depression Inventory (BDI) was used to assess the subjects'depression stati. RESULTS The average BDI score of the clinical nurses was 8.9+/-7.5, with 59% belonging to the normal category, 28% having mild depressive symptoms, and 13% with a moderate degree of depressive symptoms. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. According to a multivariate regression analysis, a significant association was found between self-esteem and social support in relation to the depression of clinical nurses. The effect of social support was found to not be significant in cases where the self-esteem was high: however, depression was significantly influenced by social support in cases where the self-esteem was low. CONCLUSION Self-esteem and social support were observed to influence the depression stati of clinical nurses. Therefore, it is suggested that an increase in depression management programs is required to create systematic management to maintain an atmosphere of high self-esteem and close relationships to manage the depression of clinical nurses.

- OBJECTIVES
This study was conducted to provide data for the establishment of a practical and the effective exercise program for managing the musculoskeletal symptoms of workers who are employed in small and medium sized enterprises. METHODS The risk factors related to musculoskeletal disease management were chosen according to the relevant literatures, and were based on advise from experts on the Delphi method. Questionnaires on selected risk factors (with a 5-point Likert scale) were given to 785 subjects who worked in small and medium sized enterprises. The subjects were then classified in the risk group when they had the symptoms and recorded at least 3 points. From those subjects in the risk group, those who had both work-related factors and general characteristics factors (with an average of at least 3 points) were further classified as the high risk group. We performed a 12-week musculoskeletal exercise program for the low and high risk groups to analyze their changes in symptoms and complaints in order to estimate the effectiveness of the exercise program. RESULTS Out of 785 subjects, 454(57.8%) were in the risk group of musculoskeletal diseases and 121(15.4%) were in the high risk group. According to multiple logistic regression analysis of the factors for the musculoskeletal symptoms in the low risk group, the significant risk factors were sex and personal disease related with musculoskeletal disease, while the risk factors in the high risk group were age, sex, and personal disease related with musculoskeletal disease. After the 12-week exercise program was performed by the low risk group, the number of musculoskeletal symptom complaints in the control group did not significantly changed, whereas for the intervention group, the number of musculoskeletal symptom complaints significantly declined for all parts of the body. After the 12-week exercise program performed by the high risk group, the number of musculoskeletal symptom complaints in the control group was significantly enhanced for the arm and elbow parts. In the intervention group, the complaint rate for musculoskeletal symptoms significantly declined only for the low back. CONCLUSION The musculoskeletal symptoms were significantly improved by the exercise program in the low risk group, but not in the high risk group. It is suggested that control measures on administrative and/or work related factors, in addition to the exercise program should be considered simultaneously for the control of musculoskeletal symptoms in groups at high risk of musculoskeletal disease.

This study was conducted to evaluate the ventilatory function in shipyard welders using the lifetime cumulative exposure to welding fumes. METHODS Ventilatory function tests were performed on 241 male welders at one large shipyard,exposed to welding fumes for over five years,and was compared to 80 male control subjects. Ventilatory function indices, such as forced vital capacity(FVC), one-second forced expiratory volume(FEV 1), ratio of FEV 1 to FVC(FEV 1%), maximal mid-expiratory flow(MMF), peak expiratory flow rate(PEFR)and maximal expiratory flow at 50 and 75% of expired FVC(FEF50 and FEF75), were obtained by analyzing forced expiratory spirograms and maximal expiratory flow-volume curves that were simultaneously measured by an Impulse ocillometry(IOS)program in the standing position. RESULTS FEF50 and FEF75 expressed as a percentage of the predicted values were significantly lower in the exposure group than in the controls, and the MMF tended to decrease.The means of all the ventilatory indices,expressed as percentage of the predicted values, were not significantly increased at the current exposure levels. The MMF, FEF50 and FEF75, expressed as a percentage of the predicted values, were significantly decreased with an increase in exposure duration.Only the FEF75 , expressed as a percentage of the predicted value, was significantly decreased with an increase in the cumulativeexposure to welding fumes(C1). The FEF75, expressed as a percentage of the predicted value, was significantly decreased with an increase in the cumulative exposure to welding fumes(C2). The above parameters were calculated to consider the current exposure level, exposure duration, application of the ventilatory system, production rate, personal protection evice, electrode and welding wire. The MMF and FEF50, expressed as a percentage of the predicted value, tended to decrease. The proportion of workers with abnormal MMF, FEF50 and FEF75 were significantly increased with an increase in the cumulative exposure to welding fumes(C2). CONCLUSIONS These findings suggested that the MMF, FEF50 and FEF75 are sensitive and practical indices for the evaluation of the ventilatory function of workers exposed to welding fumes, when the lifetime cumulative exposure(C2) is considered as a factor affecting exposure.

- OBJECTIVES
This research attempts to investigate the relationship between health risk factors and workers'behavioral changes based on individual worker's characteristics to allow the development of more effective health promotion programs in businesses places. METHODS A questionnaire survey was conducted with 282 workers employed in small to medium sized enterprises in the Kyong-in area of Korea. The questionnaire was composed of general characteristics, a health risk assessment and an evaluation of the stage of behavior change for health promotion strategy in the workplace. RESULTS The health risk assessment revealed that 65.7 % of male workers smoke, 70.5% of male workers do not exercise on a regular basis, 86.1 % of female workers do not exercise at all, and 78.6 % of male workers and 50 % of female workers drink alcohol. In addition, the survey identified that 29.5% of male workers are addicted to excessive drinking, as are 11.1% of female workers. Based on the four stages of behavioral changes that lead to health, the pre-contemplation stage, contemplation stage, action stage, and maintenance stage, 40.5 %, 23.7 %, 12.1 % and 23.7 % of workers are in these stages, respectively, with regards to quitting smoking. As for regular exercises, 18.4 %, 37.6 %, 17.7 %, and 26.3 % of workers belong to each stage, respectively. As for moderation in drinking, 20.9 %, 15.4 %, 10.0 %, and 53.7 % are in each stage, respectively. The rate of health managers in the active stage of quitting smoking is significantly higher than that of general workers. Among the workers who do not exercise on a regular basis, workers over 50 years-old and blue color workers are more common in the precontemplation stage than any other worker groups. CONCLUSIONS The results of this study suggest that the stages of behavioral change vary with worker characteristics. An awareness of the effects of the high risk factors is essential for promoting workers'attendance in health promotion programs.

- OBJECTIVES
This study was conducted to assess the concentration of xylene exposure and exposure variability of a similar exposure group(SEG) in accordance with job title and confined space. METHOD The study subjects included 28 workers working in the painting process in the ship-building industry. Measurement of subjects were repeated three times. Within and between-worker exposure variance components were estimated from log-transformed exposure concentrations employing a one-way nested random effects analysis of variance model. A uniformly exposed group was defined as one where the between-worker variance(sigmaB2) was less than or equal to 0.031 or bwR95 RESULT The results indicated that, contrary to popular belief, similar exposed groups based on job title were heterogeneous. The between-worker variance(sigmaB 2) is large(>or=0.031) and the ratios of the 97.5th and 2.5th percentile workers of the log normally distributed exposures of each group of workers was more than 2. However dividing job title into confined space(in-block, out-block, in/out-block) decreased the between-worker exposure variability. CONCLUSION This study focused on the quantitative aspects of exposure in painters in the ship-building industry. We cannot accept the assumption that SEG are uniformly exposed, as a major component of variation in exposure relates to differences in tasks or other factors. Therefore, the observational schemes can be improved by investigating jobspecific task and practice.

- OBJECTIVES
This study was carried out in order to raise workers'recognition of the effects of respirator use by providing concrete and practical data. METHODS Twenty-six workers who dealt with toluene based ink and diluents at a gravure printing office in Seoul were investigated. The toluene exposure level and urinary hippuric acid level were monitored under respirator non-wearing(RNW) and under respiratory wearing(RW) conditions. RESULTS The mean concentrations of toluene exposed to each worker through the air of gravure printing office were 147.52+/-57.34 and 134.55+/-52.44 ppm on respirator non-wearing day and respirator wearing day, respectively. There was no significant difference in toluene exposure concentration for the two days. The mean concentration of urinary hippuric acid in RNW and RW groups were 1.51 (0.53) g/L and 0.49 (0.14) g/L, respectively, as measured at the end of the workday. There was a significant difference seen in urinary hippuric acid concentration between the two days. The urinary hippuric acid concentration began to increase at 4 hours after the start of the workday(13:00) in RNW. However, there was no significant increase until the end of the workday in the case of RW. The urinary hippuric acid concentration in RW reduced 89.3% as compared with the concentration seen in RNW. There was a significant correlation between the toluene concentration and the urinary hippuric acid concentration in RNW. The regression equation was Y (urinary hippuric acid concentration, g/L) = 0.007 X x(toluene concentration in the air, ppm) + 0.665. CONCLUSIONS Our results indicate that the respirator intercepted most toluene that may have been absorbed into the respiratory organs, and suggested that properly wearing a respiratory such as wearing the respirator during the entire workday and performing a proper fit test played an important role in the protection from toluene exposure

- OBJECTIVES
The main purpose of this study was to investigate relationship between cumulative trauma disorders(CTDs) and the types of workstation and chair in workers with repetitive motion tasks. METHODS The study subjects were 77 repetitive motion tasks workers at small manufacturing industries in Seoul and Gyung-gi district area. A questionnaire was used to obtain about health practice for prevention and prevalence of CTDs by worker. The type of Workstations and chairs in workers were measured and analyzed with prevalence of CTDs by logistic regression. RESULTS Eighty-six percent of workers recognized that work posture was related to workstation and chair. Most employers and employees didn't follow the work practice guidelines for workers with repetitive motion tasks. The prevalence of CTDs was 64% by questionnaire. The prevalence of pain in shoulder, neck, back, and arm were 38%, 15%, 6%, and 5%, respectively, and the pain started after working an average duration of 16.5 months. The CTDs symptoms were significantly related to thickness of workstation, height of workstation, length of knee depth under workstation, height of back rest, height of seat pan, depth of sitting surface, width of sitting surface, and length from workstation surface edge to shoulder. By multiple regression analysis of each risk factor, prevalence of CTDs was highly correlated with height of back rest, height of seat pan, and depth of sitting surface. CONCLUSIONS This study suggests that workstations should be made adjustable for height and chairs should be equipped with seat pan height control, enough sitting surface for depth and width, back rest height and angle control. The workers should use the right working postures, exercise for health, occupational health education, and rest breaks and the manager of company should be educated for the preventing of CTDs.

- OBJECTIVES
This study was carried out to determine the knowledge(K), attitude(A) and practice(P) on major industrial safety and health problems among on-the-job training students. METHODS We used self-administered questionnaire regarding rules or regulations, the management of hazardous materials, the work place hygiene, the use of protective device, arrangement and improvement job site, ventilation, safety and health education, and inspection and management of equipment. RESULTS In general, the mean score of KAP in educated group compared with non-educated group was significantly higher. As increasing the frequency of education, the mean scores of KAP were increased. There were not significant differences among 'work duration' groups on total mean scores of knowledge and practice. But on that of the attitude, there was significant differences among 'work duration'groups. There were significant differences among 'size of enterprise'groups on total mean scores of knowledge and attitude. But on that of the practice, there was no significant differences among'size of enterprise' groups. In stepwise multiple regression analysis, education frequency and method were significantly attributed to KAP, but the coefficient of determination were low. CONCLUSIONS it is suggested that the increase of education time was the most important thing for improving the knowledge, attitude and practice on industrial safety and health in technical high school students.

- OBJECTIVES
The purpose was to investigate the distributions and the effects of genetic polymorphism of aldehyde dehydrogenase 2(ALDH2), cytochrome P450 1A1(CYP1A1), and cytochrome P450 2E1(CYP2E1) on the toluene metabolism. METHODS The subjects consisted of 160 workers who were exposed to toluene in different industries such as paint manufacturing, painting on steel and wood products, printing, bonding, and coating. The exposed toluene level was monitored by passive air sampler, and the questionnaire variables were age, sex, smoking, drinking, previous nights drinking, use of personal protective equipment, work duration, and taking benzoic acid containing food. The urinary hippurric acid collected in the end of shift was corrected by urinary creatinine concentration. The genotypes of ALDH2, CYP1A1, and CYP2E1 were investigated using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) methods with DNA extracted from venous blood. RESULTS The geometric mean and the geometric standard deviation of urinary hippuric acid concentration were 0. 44 g/g creatinine and 2. 80. The urinary hippuric acid concentration was significantly related to personal exposed toluene level among personal exposed toluene level, use of personal protective equipment, and benzoic acid containing food diet. The slope differences of the regression for ALDH2, CYP1A1, and CYP2El genetic polymorphism, age, smoking, and work duration tended to be significant. In multiple regression analysis, the regression coefficient of toluene, ALDH2, CYP1A1, CYP2E1 genetic polymorphism were significant. CONCLUSIONS Prom the above results, urinary hippuric acid level after toluene exposure was significantly affected by the genetic polymorphism of ALDH2, CYP1A1, CYP2E1. It is needed further investigation of the urinary hippuric acid level considering the effect of genetic polymorphism.

- OBJECTIVES
Work-related upper extremity disorders of the tendons, nerves, and musdes associated with. repetitive motion represent an increasing proportion of occupational illnesses, medical services, and workers' compensation costs. Severe local muscle fatigue may be a precursor of repetition strain injuries. The demand for objective and quantitative assessment of local muscle fatigue is now increasing. The purpose of this study is to determine the usefulness of power spectral analysis of individual muscle as one of the objective spectral parameters in quantification of local muscle fatigue. METHODS From 10 normal male without neuromuscular dysfuction, motor unit action potentials (MUAPs) of three muscles (upper trapezius, infraspinatus, and anterior deltoid) of left shoulder girdle were obtained. The surface electrodes were used and the changes of power spectrum according to frequency components were calculated per minute during the keyboard task for 30-minute period by power spectral analysis of MUAPs signal. RESULTS There was a linear relationship between median frequency (MF) and time flow in the upper trapezius muscle, however the same was not observed in other muscles. The MF slope of the upper trapezius muscle showed a decline of the MF over time and reflected the fatigue rate. Other spectral parameters, such as mean frequency and total power were not significantly correlated to time flow during the keyboard task in all three muscles. And no significant correlation was observed between keying rate and slope of median frequency of upper trapezius muscle. CONCLUSIONS Above results suggested that the power spectral analysis on median frequency in upper trapezius muscle would be useful in quantification of local muscle fatigue during the keyboard task and local muscle fatigue of shoulder was affected by static posture, not by keying rate.

- OBJECTIVES
In order to evaluate the stage of behavior change for health promotion strategy in workplace METHODS: Questionnaire survey was carried out for 309 workers who employed in H Electronics company in Kyongin area from September to October 1998. RESULTS According to need assessment of four step such as precontemplation stage, contemplation stage, action stage, maintenance stage which were to change of behavior for health promotion, the percent for quitting smoking were observed 48.8%, 43.1%, 8.1%. 0 %, and for the restriction of drinking were 29.8%, 10.6%, 9.3%, 5.3%; for fitness 11.1%, 31.0%, 37.3%, 20.6% in male 26.6%, 27.8%, 26.6%, 19.0% in female, for regular diet 26.1%, 19.8%, 38.7%, 15.3% in male, 27.8%, 22.2%, 40.0%, 10.0 % in female and for stress management 5.8%, 10.6%, 8.7%, 75.0% in male, 13.6%. 22.7%, 19.7%, 44.0% in female. In heavy smoker (p=0.017) and heavy drinker, (p=0.021) the percent of precontemplation stage was significantly higher than in lower drinker and light smoker. CONCLUSIONS This study suggested that company support for health promotion in workplace was weak and workers of high risk group for smoking and drinking were in precontemplation stage. So before conducting the health promotion program, health risk appraisal and need assessment for stage of behavior change should be taken for the efficient heath promotion strategy.

- OBJECTIVES
This study was planned to compare the epidemiological features such as radiological and clinical features between coal worker's pneumoconiosis and manufacturing pneumoconiosis in connection with their age and dust exposure duration. METHODS For the study, detailed examination records of those workers who had been confirmed to have pneumoconiosis in coal mining and manufacturing industries by the Ministry of Labour during two year period of 1991 and 1992. Total number of study subjects was 895 pneumoconiosis cases; 504 from coal mining and 391 from manufacturing industries. Information variables for the data analysis were sex, age, dust exposure duration, work position as the independent variables and radiological pneumoconiosis category, pulmonary function test results and pulmonary tuberculosis complication status as the dependent study variables. RESULTS There was a significant difference in distribution of radiological categories of both pneumoconiosis groups. The proportion of suspicious and category 1 pneumoconiosis was higher in manufacturing pneumoconiosis group than in coal mine pneumoconiosis group whereas category 2 and large opacity pneumoconiosis was higher in coal mine pneumoconiosis group than in manufacturing pneumoconiosis group. Major ventilatory indices such as FVC and FEV1 were significantly lower in coal mine pneumoconiosis group than in manufacturing pneumoconiosis group even after other variables such as age and smoking history were statistically adjusted for. CONCLUSIONS: It is suggested that some selected outcome variables such as radiological category of pneumoconiosis, ventilatory impairment, and pulmonary tuberculosis complication rate were significantly different between coal mine pneumoconiosis and manufacturing pneumoconiosis.

- This study was conducted to investigate knowledge and attitude factor related to hearing conservation and to evaluate the effect of knowledge and attitude about noise on hearing conservation behavior and hearing loss among workers exposed to noise. We investigated the questionnaires of knowledge and attitude about noise and hearing conservation behavior and hearing loss among 355 study subjects from March, 1998 to June, 1998. The results were as follows; We extracted following 5 factors from 26 questionnaire items of knowledge and attitude about noise; knowledge of noise and concern to the control noise (factor 1), general perceived susceptibility (factor 2), relative perceived susceptibility compared with colleagues(factor 3), concern to the hearing protective devices(factor 4), concern to the hearing and noise assessment (factor 5). Knowledge and attitude factors affecting the hearing conservation behavior were general perceived susceptibility in the case of wearing hearing protective devices and knowledge of noise and concern to the control noise in the case of suggestion for hearing conservation. But, in the case of intentional avoiding noise exposure, concern to the hearing protective devices was a significant factor with concern to the hearing and noise assessment. Knowledge and attitude factors affecting hearing loss in 1 kHz were relative perceived susceptibility compared with colleagues and concern to the hearing protective devices, and in 4 KHz were relative perceived susceptibility compared with colleagues and general perceived susceptibility.

- Executing detailed examination for cumulative trauma disorders(CTD) for all the workers with repetitive operators is not desirable considering the cost-effectiveness. Screening test with subjective symptoms, physical examination and hand strength test to detect the proper subject for secondary detailed examination is needed. The purpose of this study was to determine normal values for grip and pinch(tip, lateral and palmar) strength to be used as a screening tool for CTD. Total of 1,018 healthy subjects without related past occupational or medical history were examined with Jamar dynamometer and pinch gage. Each hand was checked twice in a posture recommended by American Society of Hand Therapists, and higher value was accepted. The results were as follows, 1. The mean grip strength of right hand in right-handed man was 47.7 kg, and 27.2 kg in woman. The mean tip pinch strength of right hand in right-handed man was 6.2 kg, and 3.9 kg in woman. The mean lateral pinch strength was 9.0 kg in man, and 5.5 kg in woman. And the mean palmar pinch strength was 9.3 kg in man, and 6.9 kg in woman. There was no significant differences in dominant hand power according to the right or the left hand dominances. 2. Selecting 10 percentile value for screening criteria for CTD, 10 percentile value of trip strength was 38 kg in man and 20 kg in woman. And that of tip pinch strength was 4 kg in man and 2 kg in woman, lateral pinch strength was 6 kg and 4 kg each, palmar pinch strength was 6 kg and 5 kg each. 3. Grip and all three pinch strengths of man showed positive correlation with age, height and weight, but in the cases of woman, only grip strength showed positive correlation with height and weight. 4. In cases of right-handed persons, dominant hand showed higher grip strength compared to the contralateral hand in 70.9% of males, and 72.9% of females. And the mean differences of bilateral grip strength was 2.7 kg(5.2%) in male, and 1.7 kg(5.7%) in female. But in the cases of left-handed persons, dominant hand did not show the significant difference in strength compared to the contralateral hand.

- This study was carried out to investigate the relationship between brain magnetic resonance imaging (MRI) and neurological findings in welders exposed to manganese fume. Thirty five welders from a bus manufacturing factory who were occupationally exposed to low dose manganese fume were examined. We collected the information on the demo graphic factors and welding careers. Laboratory investigations included blood and urine manganese concentration and blood chemistry. Brain MRI was checked, and high signal intensity of the globus pallidus was graded from 0 to 3 compared to the white matter of the frontal lobe. Neurologic examination wart carried out. The results were as follows ; 1. The mean age of workers was 48.3+/-5.7 years, mean duration of welding was 21.4 +/-5.6 Years. 2. On brain MRI, high signal intensity in the globes pallidus was observed in 27 workers (77.1%) Among them, 18 cases (66.7%) showed remarkably high signal intensity (grade 2) Mean concentration of blood manganese was higher in those with high signal intensity and correlated to the grade of high signal intensity (p=0.02) 3. On neurologic examination, no workers showed the finding of typical parkinsonism. But 11 workers (31.4%) showed subtle neurological abnormalities such as gait without associated arm movement, postural instability, intention tremor, and so on. Blood manganese concentration of neurologically abnormal group was 2.4+/-0.7 microgram/dL, which was significantly higher, compared to 1.8+/-0.7 microgram/dL of neurologically normal group (p=0.03). 4. Among 27 workers who showed high signal intensity on brain MRI, 10 workers (37%) were neurologically abnormal. Higher grade of signal intensity on globus pallidus showed higher rate of neurologic abnormality (p<0.05) Especially postural instability and gait without associated arm movement were prominent findings. These bindings suggest that high signal intensity on brain MRI might be associated with a prodromal sign of manganese intoxication. Careful neurologic examination should be tool lowed up on welders showing high signal intensity in the golbus pallidus of brain MRI.

- Before and after conducting the health promotion program by group occupational health service during 5 years, we surveyed knowledge, attitude and practice about general health(30 items) and occupational health (30 items) among 25 small and medium scale industry workers (before : 355 workers, after : 279 workers) for evaluation of effectiveness. The scores of knowledge for smoking, drinking, cholesterol, mental stress, management of hypertension, and risks in younger or women workers were significantly increased after conducting group occupational health service. The scorers of attitude for controlling of fatty food consumption and cleaning workplace and bathing for health and that of practice for taking the periodic health examination and choking blood pressure were significantly increased but most of items in attitude and practice didn't be changed after services. According to sex, the scorers of men were significantly increased in knowledge of general health, but there were not significant differences in age, job status and work duration group. In conclusion, through the group occupational health service during 5 years, only the scores of knowledge in general health were increased. It suggested that the effective program which can change workers' attitude and practice for health promotion, should be developed and conducted in small and medium scale industry workers.

Abstract
PDF
- The number of foreign workers, which has increased since 1989, can be classified into industrial trainees and illegal migratory workers. As of January 1995, the official number of foreign workers reached 49,805 according to the Ministry of Labor. But the real number is estimated to be around 100,000 and industrial trainees are 22,583 among them. The stress induced by the culture shock, 3D (dirty, difficult and dangerous) working conditions, and illegal status of the foreign workers is greater than that of regular Korean workers. By using a psychological well-being index (PWI) measuring stress on 144 foreign workers, it was revealed that 68 people experienced "high risk stress", 76 "latent stress", and the average score was 62.8. The overall stress level was very high. Considering the distribution of high risk stress group and latent stress group by socio-demographic factors, the percentage of high risk stress group was higher among workers whose contract periods are less than 2 years than among workers whose contract periods are longer than 2 years. And the percentage of high risk stress group was higher when the number of workers at factory becoming larger, and also higher among workers who can not communicate well than among workers communicate well. After having a multiple stepwise regression analysis to find the socio-demographic factors which influence the PWI score, we found that the PWI score goes higher when the contract period is becoming shorter and the work hours is becoming longer, and these two factors are able to explain the score to the level 16.3%.
