This study was conducted to assess the effects of noise exposure and psychosocial factor on blood pressure in manufacturing workers. The study subjects are 414 workers (243 males, 171 females) employed at the noisy department. The mean age of low exposed group (<85dB) was 34.65+/-9.53 years, and that of high exposed group (> or =85dB) was 36.37+/-11.15 years. The difference in mean age wart not significant. The mean and distribution of working duration, smoking status, drinking status were not significantly different between two groups. The mean systolic blood pressure of the low exposed groups was 120.01+/-12.06 mmHg, and that of high exposed group wart 126.27+/-13.84 mmHg. The mean diastolic blood pressure of the low exposed and the high exposed group were 77.18+/-10.83 mmHg, and 83.46+/-11.22 mmHg respectively. These differences of blood pressure were statistically significant(p<0.05). The workers in noisy department have significantly less work environmental satisfaction, higher job demand, and higher social support. The mean values of psychosocial distress were higher in the workers of the noisy department, but the difference was not statistically significant. This study was to speculate whether the work environmental satisfaction and social supports modify the association between the noise exposure level and the blood pressure. The results showed that work environmental satisfaction could not modify the association between the blood pressure and the noise exposure. Social support at work did not modify the association. Furthermore, we evaluated the high job strain from a combination of high job demand and low job control at work. Compared to the low strain group, the olds ratio of the high job strain group for hypertension in diastolic blood pressure were statistically significant, but not in systolic blood pressure. Hierarchical multiple regression analysis was used to determine whether the independent variables contributed to explaining the blood pressure. After controlling for possible confounders, we found that the noise exposure level was a correlate of the diastolic blood pressure. But no association between the noise exposure level and the systolic blood pressure. No significant result was found for psychosocial factor.

Although stroke is a great public health challenge in Korea, there have have been few epidemiologic studies of the risk factors stroke. A case-control study was performed to evaluate the risk factors for hemorrhagic stroke in Wonju, Korea. Ninety-five subarachnoid hemorrhage (SAH) and 102 intracerebral hemorrhage (ICH) patients aged 21-86 years, and 267 controls were recruited among the inpatients of Wonju Christian Hospital during 1994-1995. Information was gathered through interview and examinations. After adjustment for age and sex, family and past history of hypertension, drinking habits, age of menarche, height, weight, body mass index, waist and hip circumference, earlobe crease, prothrombin time, white blood cell count, hemoglobin, and total cholesterol were all found to be significantly associated with both SAH and ICH. The risk factor significantly associated only with ICH was smoking habits. In multiple logistics analyses, the independent risk factors for SAH and ICH were the same. Those included family and past history of hypertension, age of menarche, earlobe crease, prothrombin time, white blood cell count, hemoglobin and total cholesterol. In general, the risk factors for SAH and ICH were similar with each other, except smoking habits. Risk factors found in this study congruent with previous studies were family and past history of hypertension, drinking habits, body mass index, prothrombin time, white blood cell count, and hemoglobin. Those incongruent or rather newly found were age of menarche, a big physique, earlobe crease, and total cholesterol.

OBJECTIVES: The Korean version of the Oswestry Disability Index (ODI) is the most widely used tool validated instrument for measuring and the level of disability associated with low back disorders. We wanted to validate use of the Korean version of the ODI in Korean farmers with low back pain. METHODS: The object of this study was to examine the reliability and validity of the Korean version of the ODI. The Korean version was tested on 53 farmers (62.3+/-10.3 years of age) with low back-related disorders. We investigated the Test-retest reliability, internal consistency, and construct validity of the ODI. The Test-retest reliability was assessed in 30 farmers within a time interval of approximately 14 to 18 days. Differences between the Korean version of the ODI and the Short Form 12 (SF-12), which includes 8 domains (general health, physical functioning, role-physical limitation, bodily pain, role-emotional limitation, mental health, vitality, social functioning) were analyzed for construct validity. The correlation of the Korean version of the ODI with the SF-12 was analyzed, as well. RESULTS: The intra-class correlation coefficient of test-retest reliability was 0.854. Reliability estimated by the internal consistency reached a Cronbach's alpha of 0.879. The correlation between 7 domains of the SF-12 except for the mental health domain and the Korean version of the ODI was statistically significant (p<0.05). Four domains (general health, physical functioning, role-physical limitation, bodily pain) that measured physical status all showed high correlations (p<0.01), as did a domain that measured mental status (role-emotional limitation) (p<0.01). CONCLUSIONS: The results showed that the Korean version of the ODI is a reliable and valid instrument to measure the level of disability in Korean farmers with low back-related disorders. The use of this instrument is recommended for future clinical trials in Korea.

OBJECTIVES: To evaluate both the psychosocial and physical effects of muscle strengthening exercise on farmers, and in so doing evaluate their effect on musculoskeletal disorders in farmers. METHODS: 28 subjects participated in our muscle strengthening exercise program. Mean age of subjects was 63+/-13 years. The exercise program was performed 3 times a week during the 8 week studys period. Before and after training various measurements were made: self esteem scale (SES), psychosocial wellbeing index short form (PWI-SF), static and dynamic balance ability, grip strength, arm curl, time up and go (TUG), functional reach, and oswestry disability index. RESULTS: The muscle strengthening exercise program increased the self-esteem, grip strength and static and dynamic balance of subjects, while psychosocial stress and low back pain levels were decreased significantly (p<0.05). CONCLUSIONS: The muscle strengthening exercise improved psychosocial and physical status of test subjects. Thus, exercise may be an effective strategy for enhancing the psychosocial and physical health of farmers.

Retrospective analysis of survival rates was undertaken in the patients of 58 cases treated with conventional radiation therapy for malignant salivary gland tumors between January 1975 and December 1984 in Korea Cancer Center Hospital (KCCH). They were patients whose long-term follow-up was possible and who had refused surgery or had had recurrences postoperatively. Out of 58 patients, 25 patients (43.1%) had mucoepidermoid carcinomas and 24 patients (41.3%) adenoid cystic carcinoma. Total actuarial survival rates at 5 years and 10 years were 68.2% and 31.8% respectively, but disease-free survival rates, 43.2% and 13.0%, respectively. According to TNM stage, the survival rates at 5 years were 86.5% in T1, 40.0% in T2 + T3, and 0% in T4. In terms of histologic types, 5 years disease-free survival rate of adenoid cystic carcinomas (40.1%) was lower than that of mucoepidermoid carcinomas (49.8%) but overall survival rate (77.3%) was much higher than that of mucoepidermoid carcinomas (51.5%). Therefore, we concluded that the patients, who had had disease after failure of treatment, could survive during a certain period of time and their alive times were 2 years on the average. There was a difference in survival rates in the mucoepidermoid carcinomas in terms of histological grade of differentiation and it was a arbiter in prognosis: 5 YSR of low-grade was 78.8% and higher 2 times than that of high-grade. There was no difference in survival rates according to location and sex. The number of patients having minor salivary gland tumors was 6 cases and their actuarial 5 YSR was 32.3%. Consequently, prognostic factors which influence the survival rates of patients with malignant salivary gland tumors are thought to be 1) histological ubtypes 2) T and N staging (AJCC) 3) histological grade, especially in mucoepidermoids.
