1.The Relationship between Noise Exposure Level in Worksite and Workers' Stress symptoms.
Korean Journal of Preventive Medicine 1996;29(2):239-254
Health services on industrial noisy environment have been provided only for noise-induced hearing loss management until now. But gradually, modern diseases and death have come to be related to stress and mental health deeply, therefore noise-induced mental disorder, like a stress became very important. In this point, the purpose of this study was to analyze the relationship between noise exposure level in worksite and workers' stress symptoms. This study included a survey of 786 manual workers selected from 89 worksites in 21 factories in Puchon. The results were as follows: 1. For demographic characteristics, most of the workers were males(80.8%), the 20~29 years old were 34.5% and those who graduated from high school were 65.3%. The workers whose monthly income ranged from 500,000 to 800,000 won were 37.5% and who have a religion were 47.9%. 2. For occupational characteristics, workers who had worked 1~5 years in the factories were 33.0%. Those who felt much for them workload were 43.9% and who worked more than 8 hours a day were 73.9 %. Those who were dissatisfied with their job and pay were 31.9% and 50.6%. The workers who responded ventilation condition of their worksites were bad were 51.9% and the dissatisfied with working environment of their wofksites were 45.9%. 3. Workers who were suffering from tinnitus were 53.3% and those who perceived hearing loss were 50.l%. Persons who reported they always wore earplugs at work were 35.4%. Those who felt earplugs bigger than their ears were 30.6% and those who experienced eardiseases caused by earplugs were 25.6%. 4. For the noise exposure level in worksite, workers who were exposed to 80-90dB were 30.3%, 90-100dB were 26.4% and 50~70dB were 19.2%. 5. workers' stress symptoms were significantly related to marital status and their monthly income p< 0.05). Workers who were single and had lower monthly income showed higher PSl (Psychiatric symptom Index) scores than those who were married and had higher monthly income. Higher PSl scores were also significantly related to l~2 days night-work per week, much for them workload, dissatisfaction with their job, and bad relationship with their bosses and coworkers. 6. Higher PSl scores were significantly related to severe tinnitus and perceived hearing loss p<0.001). Workers who felt the earplugs they use did not fit their ears showed significantly higher PSl scores(p<0.01). Workers who reported that they did not feel they need earplugs showed significantly higher PSl scores(p<0.05). Increased experience of eardisease caused by earplugs that did not fit were also significantly related to higher PSl scores(p<0.001). 7. The higher noise exposure level in worksite from 80dB was, the more severe stress symptoms including PSl subparts were reported; Anxiety, Anger, Depression, and cognitive disorder(p<0.001). 8. According to the results of stepwise multiple regression analysis, factors affecting workers' PSl scores were perceived hearing loss(R2=0.160), noise exposure level jn worksite(R2=0.110), relationship with coworkers, amount of workload, monthly income and relationship with bosses orderly and the total R2 of this 6 factors was 0.371. 9. The most significant factors that have impact on manual workers' stress symptoms were perceived hearing loss and noise exposure level in worksite, especially noise exposure level in the worksite was the most affective factor on the depression symptom.

PURPOSE: This study was to examine the effect of postpartum exercise on mental health. Mental health comprises a 9 symptom dimension of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid Ideation, and Psychoticism. METHOD: A non-equivalent pre-test, post-test control group study was conducted. Fifty-two puerperal women who were admitted to a postpartum ward of a mother-baby clinic in Pusan were recruited; 26 women were assigned to the experimental group and 26 women to the control group. Postpartum exercise was applied to the experimental group from postpartum day 3 for a period of 8 weeks while no exercise program was applied to the control group. Mental health with SCL-90-R was measured before and after exercise. Data was analyzed using mean, x2-test, t-test, and ANOVA by SPSS 10.0. RESULT: The mental health status in the exercise group did not show a statistically significant decrease when compared to that of the control group. CONCLUSION: There is no effect of postpartum exercise on women's mental health during the first 8 weeks of the postpartum period. Further studies are needed for randomized clinical trials with a larger sample size.

Demand for high quality medical care has recently been increasing in step with high level of income and education. Patients prefer the use of large general hospitals to small community hospitals. Large hospitals, usually located at urban area, expand their capacities to cope with the increasing demand, therefore, they easily secure revenue necessary for growth and development of hospitals. However, small community hospitals are facing with serious financial difficulties caused from the reduction of patients in one hand and the inflation of cost in another. If small rural hospitals were closed, the closure would have negative impacts on local economies in addition to the decrease in access to medical care. Community leaders should have an insight on the contribution of community hospitals to local economies. They could make a rational decision on the hospital closure only with the understanding of hospital's contribution to the community. This study is designed to develop an economic model to estimate the contribution of rural hospital to local economies, and also to apply this model with a specific hospital. The contribution of a hospital to local economies consists of two elements, direct effect and multiplier effects. The direct impacts include hospital's local purchasing power, employee's local purchasing power, and the consumption of patients coming from outside the community. The direct impact induces multiplication effect in the local economy. The seed money invested to other industries grows through economic activities in the economy. The seed money invested to other industries grows through economic activities in the region. This study estimated the direct effect with the data of expenditure of the case hospital. The total effect was calculated by multiplied the direct effect with a multiplier. The multiplier was drown from the ratio of marginal propensity of income and expenditure. Beside the estimation of the total impacts, the economic effect from the external resources was also analyzed by the use of the ratio of patients coming outside the region. The results are as follows. 1. The direct economic contribution of the hospital to the local economy is 1,104 million won. 2. The value of multiplier in the region is 2.976. 3. The total economic effect is 3,286 million won, and the multiplication effect is 2,182 million won. 4. The economic contribution from the external resources is 245 million won which is 7.5% of the total economic effect.

8.Effects of Postpartum Exercise on Pelvic Muscle Contraction, Body Composition, and Physical Fitness of the Postpartum Mother.
Korean Journal of Women Health Nursing 2004;10(3):244-251
PURPOSES: This study was to examine the effects of postpartum exercise on pressure of the pelvic muscle contraction, body composition and physical fitness of postpartum mothers. METHOD: A nonequivalent pre-test, post-test control group study was conducted. Fifty-two postpartum mothers (experimental group, 26; control group, 26) admitted to a postpartum ward in a Busan mother-baby clinic were recruited. Data was analyzed using mean, chi2-test, and t-test by SPSS 10.0. RESULT: Body fat mass (t=-3.196. p= .002), body fat rate (t=-3.831, p= .000), and fat distribution (t=-3.026, p= .004) of body composition increased significantly in the experimental group after the postpartum exercise as compared with the control group. After an 8 week exercise program, the pressure of the pelvic muscle contraction in the experimental group was significantly higher than in the control group (t=3.329, p=.002). In the change of physical fitness, grip strength of the hand, back muscle strength, and trunk flexion forward were not significantly changed, but trunk backward extension in the experimental group significantly increased (t=1.950, p=.050). CONCLUSION: Postpartum exercise affects pelvic muscle contraction, body composition, and physical fitness of the postpartum mother.

The technique of radial artery cannulation and its complications are well documented, but serious complications are rare. This is a report of one case of amputation of wrist due to finger necrosis developed from the radial artery cannulation in patient who had craniectomy surgery. This 52-year-old 79 kg male underwent subdural hematoma removal surgery. Right radial artery cannulation was carried out percutaneously using 22 gauge Teflon extracath needle after modified Allen's test appeared to be positive. It was intermittently flushed by heparinized solution. His arterial blood pressure was maintained 100/70-110/80 mmHg and 5 units of banked whole blood and 1 unit of fresh frozen plasma were transfused during 8-hours operation. Cannula was removed on the 9th hour after operation because that was obstructed. On the 12th hour after removal of cannula, his right hand noted to be cool and cyanotic. So, warm towel and hot bag applied continuously on the right hand and the right stellate ganglion block was carried out every day for 4 times. However, on the 10th day after removal of cannula, necrotic change of all fingers of the right hand became worse and skin of fingers were shrunken. Therefore, disarticulation of the right wrist carried out on the 71th day of his hospitalization.
