This study was performed to investigate the knowledge and attitude of workers in small scale industries on health management, and to provide the basic data for more effective service by the group occupational health service system. The knowledge and attitude of 247 workers and 46 health personnel in the industries scattered around Incheon were investigated from December 1992 to February 1993. The results were summarized as follows; 1. There were significant differences between the workers and the health personnel by age, sex, marriage status, job-position and education level. 2. The recognition level of the workers to contract work related disease was significantly higher than that of health personnel, and recognition level of the workers on environmental hazards and on the utility of measuring hazards were lower than that of health personnel. 3. The recognition level on the content of the group occupational health service system was significantly different between workers and health personnel, 72.6% of the responses from the workers answered that they did not know what the group occupational health service system was, but 82.2% of the responses from the health personnel answered that they knew well what it was. And 79.0% of all respondents thought it was necessary for worker's health. 4. seventy three percent of the respondents from the workers indicated that they had never taken health education. However, 93.0% of all respondents answered positively for the need of health education to promote their health. 5. current health service system was judged to be insufficient for the demand of workers for better health. Most of the respondents prefered a formal but flexible health service system and they wanted the periodic health examination to be followed up. It was revealed that despite of poor knowledge, the demand of workers for health service was higher than the current supply. Therefore, this study suggests that educating both health personnel and workers to obtain correct knowledge on the hazards to work environment and health management is needed for effective occupational health service.

An Analysis of Determinants of Elderly Medical Costs Inflation Using Deterministic Model.
Korean Journal of Preventive Medicine.1994;27(1):135-144.
The purpose of this study compares determinants of eldery medical cost inflation with those of other age groups by analysing aggregated data with a deterministic model. The deterministic model of per capita medical cost inflation consists of increases in price, intensity of services, and medical utilization. We used a time series data (1985-1991) from National Medical Insurance and analyzed by age groups. In total population, the average increase rates of inpatient and outpatient medical costs were respectively 9.5% and 8.8% during 6 years and the major cause of inflation was the increase in service intensity in both of inpatient and outpatient cases. But in the population of 65 years old and over, the average increase rates of inpatient and outpatient medical costs were respectively 13.8% and 14.8% and the major cause of inflation was the increase in per-capita medical utilization in both of inpatient and outpatient cases. Also, the increase in service intensity of 65 years old and over was the highest of other age groups. This pattern was similar during study periods. we concluded that the level of medical cost inflation and the determinants in elderly was the highest-especially in per capita medical utilization, therefore, the inflation of medical costs in elderly will be higher than other age groups for the further in Korea.

Effects of Regional Medical Insurance on Utilization of Medical Care in Urban Population.
Korean Journal of Preventive Medicine.1994;27(1):117-134.
The effects of regional medical insurance on utilization of medical care in urban population was examined in this study. The data was collected in a 2-year follow-up household survey conducted at Taegu city before and after implementation of the regional medical insurance. The study population was divided into 2 groups. Cohort I was the uninsured in 1989 and cohort II was the insured in 1989. After the coverage of medical insurance, physician visit rate per 1,000 population, use-disability ratio and use-restricted activity ratio in cohort I were increased compared to cohort II in both of acute and chronically ill people. The use-disability ratio and use-restricted activity ratio of the insured poor were lower than those of the insured nonpoor in both of cohort I and cohort II. The major reasons for pharmacy use were accessibility and affordability before the coverage of medical insurance in cohort I, however, after the coverage of medical insurance, the important reason was accessibility rather than affordabifity. In logistic regression analysis of physician visit, the significant independent variables were acute illness episode(+), chronic illness episode(+) and income(+) in both of cohort I and cohort II. In cohort I, after the coverage of medical insurance, more people replied that the medical cost of hospital and clinic was reasonable. The people who covered by the regional medical insurance were more dissatisfied with the imposed premium than those who covered by other types of medical insurance in both of cohort I and cohort II. More people in cohort II than cohort I were dissatisfied with the services from hospitals and clinics after implementation of the regional medical insurance. In conclusion. after the coverage of medical insurance, the gap between the poor and the nonpoor still exists in terms of medical care utilization.

The united states adopted DRG based prospective payment system (PPS) in order to control the inflation of health care costs. No study used statistical test while many studies reported the cost containing effect of the PPS. To study impacts of the PPS on the Medicare expenditure, this study set the following three hypotheses: (l) The PPS decelerated the increase in the hospital expenditure (part A), (2) the PPS accelerated the increase in the expenditure of outpatients and physicians (part B), (3) the increase in total expenditure was decelerated inspite of the spill over (substitution) effect because saving in the part A expenditure were greater than losses in the part B expenditure. The dependent variables are per capita hospital expenditure, per capita part B expenditure, and per capita total expenditure for the Medicare beneficiaries. An intervention analysis, which added intervention effect to the time series variation on the Box-Jenkins model, was used. The observations included 120 months from 1978 to 1987. The results are as follows: (l) The annual increase in the per capita part A expenditure was $5.11 after the implementation of DRG where as that before the PPS had been $11.1. The effect of the reduction ($5.99) was statistically significant (t=-3.9). (2) The spill over (substitution) effect existed because the annual increase in the per capita part B expenditure was accelerated by $l.73 (t=l.91) after the implementation of the PPS. (3) The increase in the total Medicine expenditure per capita was reduced by $4.26(t=-2.19) because the spill over effect was less than cost savings in the Part A expenditure.

Effects of Hyperoxia on 8-Hydroxydeoxyguanosine Formation in Carbon Monoxide Exposed Rats.
Korean Journal of Preventive Medicine.1994;27(1):84-106.
Hyperbaric oxygen(HBO) therapy for carbon monoxide(CO) poisoning eventually inducing the hypoxia-reoxygenation condition, may produce oxygen free radicals, which forms 8-hydroxydeoxyguanosine(8-OH-dG) by attacking C-8 position of deoxy-guanosine (dG) in DNA. Effects of oxygen partial pressure or duration of HBO therapy with or without CO poisoning on the tissue 8-OH-dG formation were investigated. Male Sprague-Dawley rats were grouped and exposed to air(control group), 4000ppm of CO for 10 to 30 minutes(CO only group), air for 30 minutes after 30 minute exposure to 4000ppm of CO(CO-air exposure group), HBO after 30 minute exposure to 4000ppm of CO(CO-HBO group), or HBO therapy for 10-120 minutes (HBO only group). The 8-OH-dG concentrations in the brain and the lung tissues were measured with high performance liquid chromatography and electrochemical detector (ECD). Average concentrations of the 8-OH-dG of each group were statistically compared. In the brain tissues, 8-OH-dG concentrations of the CO only group, the CO-air exposure group, and the CO-HBO group did not significantly differ from those of the control group. Similar insignificance was also found between the CO-HBO group and the HBO only groups. No appreciable dose-response relationship was observed between the 8-OH-dG concentration and the oxygen partial pressure or the duration of HBO. However, the 8-OH-dG concentrations of the 30 minute CO only group were higher than those of the CO-air exposure group (p-value<0.05). In the lung tissues, there were no significant differences between the 8-OH-dG concentrations of the control group and those of the CO only group, the CO-air exposure group, and the CO-HBO group. However, mean 8-OH-dG concentration of the CO-air exposure group was significantly higher than that of the CO only group under the same CO exposure condition(p-value<0.05). With the duration of CO exposure, the 8-OH-dG concentrations of the lung tissues decreased significantly (p-value<0.05). The concentrations of 8-OH-dG in the lung tissues proportionally increased with the duration of HBO, but no such relation was observed with the oxygen partial pressure. These results suggest that the brain may be more resistant to oxygen free radicals as compared with the lungs, and that oxygen toxicity following HBO may be affected by factors other than oxygen free radicals.

To investigate the sleeping patterns and gastrointestinal disorders of shift workers, the auther studied 434 female workers who worked at textile industry ill Taejon city from september 1 ,1992 to september 31 ,1992. Shift pattern were divided into 3 categories; 3 shift (shifts per 8 hours), 2 shift (day and night shift) and day work. The results obtained were as follows: 1. The average sleeping hours when adjusted for the education level of the total study subjects was 6.1 hours. That of 3 shift workers was 6.1 hours, 2 shift workers was 6.0hours, but that of day workers was 6.5 hours. There were no significant difference among the shift workers. 2. For the 3 shift workers, the average physiologic adjusted duration in day shirt(2.2 days) was shorter than that or night shift(2.7 days) and there were significant difference among the rotating shift works (P<0.001). The sleeping problems in day shift was less than those of night shift (P<0.001). 3. 44.9% of 3 shift workers, 39.3% of 2 shift workers and 33.1% of day workers complained gastrointestinal symptoms when adjusted for the age, education level, job tenure, work post. And the rates of gastrointestinal symptoms complained increase with job tenures (P<0.001). 4. The most frequent gastrointestinal diseases were gastitis and gastric ulcer with 14.2 %, Irritable bowel syndrome with 3.1%, duodenitis and duodenal ulcer with 2.1% and combined gastrointestinal disease with 2.1%. Age, eating habit, amount of coffee per day, job tenure, work post and shift pattern showed no significant difference with the gastrointestinal diseases when adjusted for the age. According to the above results, the auther suggested that the shift pattern and job tenure can affect to the sleeping problem and gastrointestinal symptoms.

A study on the repeat tests for diagnosis at a tertiary hospital in Taegu city.
Korean Journal of Preventive Medicine.1993;26(3):457-468.
This study was conducted to investigate the repeat test rate for diagnosis at a tertiary hospital for the outpatients who were referred themselves to the hospital by the clinics and other medical facilities. The study population consisted of 498 patients who visited outpatient department of internal medicine, general surgery, orthopedic surgery and neurosurgery in the hospital between March 16 and April 11, 1992. This study was surveyed by the questionnaire about the tests for diagnosis at first level medical facilities, and then, was investigated by the medical record about the tests for diagnosis at a tertiary hospital. The proportion of test among the patients who utilized the first level medical facilities was 20.9% for the X-ray test, 10.6% for the urinalysis, 9.0% for the electrocardiogram, 3.4% for the computer tomogram and 6.4% for the ultrasonogram. At the tertiary hospital, the X-ray test was 45.2%, the liver function test was 24.7%, the urinalysis was 19.1%, and the electrocardiogram was 15.7%. The proportion of patients who possessed results of test for diagnosis at the first level medical facilities was 76.5% for the computer tomogram, and 31.3% for the ultrasonogram. As the repeat test rate between the first level medical facilities and the tertiary hospital, the thyroid function test was the first rank as 71.4%, the second rank was the routine CBC as 67.9%, and the third rank was the X-ray test as 64.4%. But among the patients that brought the result for tests at the first level medical facilities, the repeat test rate was as follow ; the routine CBC was 75.0%, the liver function test was 72.7%, and the computer tomogram was 15.4%.

A study on the determinants of hospital profitability.
Korean Journal of Preventive Medicine.1993;26(3):442-456.
Financial stability is the foremost prerequisite for the continuous growth and development of hospitals. The present study aimed at developing a deterministic model using the factors which affect the hospitals profitability and at discovering which factor affected the hospital profitability. The study conducted questionnaire surveys on all general hospitals, with the exception of special hospitals, with over eighty hospital beds. Of the 274 subject hospitals, 136 of them, consituting 49.6% of the whole, were used in the study. The results are as follow. 1. In the deterministic model, outpatient revenue was affected more by the number of physician visits than by outpatient service intensity. Inpatient revenue was found to be affected more by the number of discharged patients than by inpatient service intensity. However, the increase rate of the service intensity not only contributed in stepping up the operating margin by 4~8% in outpatient and 3~6% in inpatient, but it was statistically significant. 2. Among the factors which determined the operating cost within the deterministic model, the number of patients had a greater impact on the operating cost than the resource consumption per patient. 3. The resource consumption per patient were proved to have the greatest effect on the profitability within the probabilistic model. The management cost per adjusted patient, in particular, was proven to have a statistically significant effect on the profitability in all hospitals.

Geographic variations in tonsillectomy and adnoidectomy (T & A) and appendectomy in Korea.
Korean Journal of Preventive Medicine.1993;26(3):430-441.
The objectives of this study are two-fold : to identify geographic variations in the rate of tonsillectomy and adenoidectomy(T and A) and appendectomy and analyze the socioeconomic variables and health resources which affect geographic variation in the rate. The nationwide three month's cases of the two surgical procedures in 1991 are obtained from the record of the National Federation of Medical Insurance. The analysis shows two to ten-fold variations in the regional rates for the performance of two common procedures such as T and A and appendectomy. T and A shows a bigger regional variations than appendectomy. As a result of multiple regression, the factor of bed supply has been found significant for the dependent variable of the rate of T and A. The findings of large variations in the rate of surgical procedures throughout the country would have important implications for allocating scarce resources and managing quality of care. Further analysis is needed for the elaboration of the above implications.
