Background
: Currently, the head trauma is acknowledged as the prime cause to death in the getting increased traffic accidents and industrial injuries. Generally, the post-treatment physical and mental sequelae which head-trauma patients mostly suffered could be developed as the critical disabilities. In this investigation, major causes, occurances and associated injuries of head trauma that were treated in our emergency room by our medical residents was evaluated in order to develop the initial evaluations that could estimate the prognosis of patients accurately.

Methods : The 209 case which admitted in our neurosurgery through emergency room from 1, January 1993 to, 31, January 1994 was evaluated as the analyzed group. All of reviewed case was involved head trauma and experienced the computerized tomography diagnosis of brain.

Results : The major cause of admitted head trauma case was turned to be traffic accidents as 78.3%. Glasgrow Coma Scale score on arrival was 58.8% in 13-15, 29.7% in 9-12, 11.5%, in 3-8. The skull fracture was estimated 28.7%, and abnormal finding in computerized tomography was 37.7% The most common lesion in computerized tomography was found as the hemorrhagic contusion, subdural hematoma, and then epidural hematoma. And, degree of abnormal finding in computerized tomography accrding to Glasgrow Coma Scale was characterized as 100% in 3-5, 99.2% in 6-8, 80.2% in 9-12, 20.6% in 13-15. The 10.5% of 209 case underthrough the operations, and the mortality rate was 2.2%. The severe associated injuries were sequentialy developed as facial fractrue, extremity fracture and chest contusion.

Conclusion : The primary cause of head turama was observed as traffic accidents. Regarding to the degree of Glasgow Coma Scale, the low score generally inclined to the skull fracture, abnormal finding in computerized tomogaphy and sequale. Therefore, the on-arrival Glasgow Coma scale could be the critical estimate in prognosis of forward outcome and sequelae.

Background
: Health status is affected by various factors-dietary habits, life style, local difference etc. The prevalence of cardiovascular disorder is increasing in Korea. Serum cholesterol level, blood sugar level, body fatness are closely related to cardiovascular disorder. We performed comparative studies of the results of periodic health examinations in insured adults of different areas.

Methods : Of the results of periodic health examination of insured adults, 3,305 subjects were gathered. 935 subjects were residents of Seoul and 2,370 subjects were residents of Chungjoo. All the subjects' serum cholesterol level, fasting blood sugar level, arterial blood pressure, and body mass index were analyzed statistically.

Results : Serum cholesterol level(Seoul : 207.66mg/dL, Chungjoo : 202.60mg/dl ; P<0.01) and fasting blood sugar level(Seoul : 92.77mg/dL, Chungjoo : 90.16mg/dL ; P<0.01) were statistically different between two areas, but arterial blood pressure and body mass index had no statistical differences. The prevalence of abnormal findings was no statistically different between two areas.

Conclusion : Geographic differences affected above mentioned index values were noted. We did not consider specific environmental factors, such as diet habit, physical activity and individual concern about health. But this study will be a supportive data for future studies of health maintenance factors in Korean.
