Regionalization of high-risk perinatal care has been advocated because intensive care for small and ill newborn infants lowers mortality and morbidity. This report is based on analysis of admissions to the Neonatal Intensive Care unit (NICU) at the Wonju christian Hospital during the 4-year period from January, 1988 to December, 1991. There were 786 inborn infants and 1155 outborn infants admitted to the NICU. The results of our study follow; 1) Mean gestational ages were 36.8 weeks in inborn infants and 39.0 weeks in outborn infants. Mean birth weight was 2.5kg in inborn and 3.0kg in outborn infants. 2) The high-risk maternal factors, such as cesarian section delivery, eclampsia, preeclampsia, multiple pregnancy and placental anomaly were significantly more frequent in inborn infants than in outborn infants. 3) Perinatal sphyxia, HMD and transient tachypnea of newborn (TTN) were more common in inborn than in outborn infants, but pneumonia, meconium aspiration syndrome, and seizure were more common in outborn infants. 4) The positivity of bacterial cultures in blood and urine was higher in outborn infants than in inborn infants. The most frequently isolated microorganism was staphylococcus species in both inborn and outborn infants. 5) Hospital days, duration of TPN, duration of mechanical ventilation, frequency of seizure, and frequency of transfusion were longer or more frequent in inborn than in outborn infants. 6) Mortality rate was higher in inborn infants than in outborn infants. 7) In outborn infants, mortality rate was higher in infants whose transporting time was longer than 2 hours than for infants within 2 hour distances. However, this difference was not statistically significant. 8) These findings suggest that many lower birth weight and severly ill infants were not transported to the NICU of Wonju Christian Hospital perhaps due to poor transport systems, distance or socio-economic status. In conclusion, the improvement of transporting systems and socio-economic conditions will be required within this region.

BACKGROUND: A lots of fires were happened every years. And then, the many peoples have died because of foe. It is important to plane for initial field emergency management that the major cause of death and injury type is analysed by large scaled fire. METHOD: We have analysed the fire victims by large scaled fire from Jan. 1995 to Dec. 1995 in Korea. We analysed systemic factors, environmental factors, patient factors which was acquired from medical records and interviews with victims, victim's famaly, rescuer. RESULT: The total number of victims are 130 and the mortality rate is 61.5% (80 patients). The major injury and cause of death were inhalation injury and trauma. The injury type of fire victims are 19 cases of inhalation injury, 13 cases of laceration,5 cases of burn,5 cases of contusion,4 cases of blephaloconjunctivitis. In fire deaths, the 78 victims (97.5%) were death associated with the gas inhalation, and the only 2 fire deaths were due to trauma. This result of the cause of death was higher inhalation injury than previously reported literature because most fires of our study was happened at the closed-maze area. CONCLUSION: When the fee was happened at closed-maze area, many victims foiled to escape the space because of smoke, toxic inhalants from combustible interior decoration, and then were death.

The objects of this study were to analyze the crown angulation, crown inclination, molar offset angle, and crown in and out of the Korean adults having normal occlusion. 14 subjects (7 male, 7 female) were chosen in the 80 subjects who had ideal occlusion and beautiful profile we thought. The casts were obtained from the subjects, and then they were scanned with 3-dimensional scanner machine. We analyzed them with computer program based upon Andrews methods and the following results were obtained. 1. We got the norm of the crown angulation, crown inclination, molar offset angle, and crown in and out in the Korean adults. 2. The analysis using 3 dimensional scanner and computer program was more fast and accurate than the manual methods.

Bone is a dynamic tissue which is constantly remodelled by subsequent cycles of bone resorption and formation. Glucocorticoid and vitamine D3 are known as regulating substances in bone metabolism. In vitro experiments using bone tissue, it was suggested that glucoccorticoid inhibits bone resorption, whereas the effect of glucocorticoid on bone formation are complex- increasing or decreasing effect. The active form of vitamin D3, 1,25-dihydroxycholecalciferol [1.25-(OH)2D3], has been reported to stimulate osteoblastic activities including the production of ALP, type I collagen, and osteoclacin. The purpose of this study was to evaluate the effect of admixture of vitamin D3 and dexamethasone, one of glucocorticoids, on osteblastic cell line(MC3T#-E1). Alkaline phosphatase(ALP) and MTT assay were conducted in the cultivated cells with 1, 10, 100nm/ml of 1,25-(OH)2D3 and/or 10nM/ml, 100nM/ml, 1micrometer/ml of dexamethasone. The observed results were as follows. 1. The activity of osteoblastic cells with 1micrometer/ml of dexamethasone was significantly increased at 1-day cultivation with comparison to control group, but was decreased afterwards. But the activity of ALP was greatest in 1micrometer/ml of dexamethasone and increased with time lapsed. 2. The activity of osteoblastic cells with vitamin D3 was significantly increased dose-dependently at 1-day cultivation, but was significantly decreased in 10nM/ml or 100nM/ml at 2-day or 3-day cultivation, and was greatest in 100nM/ml at 3-day cultivation. 3. In case of admixture of dexamethasone and vitamin D3 at 2-day cultivation, but was increased again at 3-day cultivation, which was greater than that in control or dexamethasone only group. The activity of ALP was decreased at 1-day cultivation, but was increased in the admixture of 10nM/ml or 100nM/ml of dexamethasone with 100nM/ml of vitamin D3 at 2-day cultivation, and was again decreased at 3-day cultivation.
