The cranial CT is a new radiological technique with which, for the first time, minimal differences anattenuation by intracranial soft tissue can be measured exactly. Th basic physical principles of CT have beenextensively presented by Hounsfield (1973). It is well established that the attenuation of extravasated blood measures between 35 and 45 houns field units. Therefore no difficulty should be encoutered in the recognition anddiagnosis of extra-axial hematoma and cerebral contusion since the density of the brain parenchyma never measures more than 25 units. As the constant increase in high velocity accidents and violence, the problem of acute headinjury is one of the matters of great importance in today's medical practice. Therfore it is very important to figure out the method that would allow us to diagnose easily and precisely the effects of trauma upon the brain inorder to institute the proper treatment at the earliest possible moment . CT allows us to make a diagnosis quickly and in a non-invasive manner. The CT scan was carried out on 310 head trauma cases in the department of radiology, St. Mary's and Kang Nam St. Mary's Hospital, Catholic Medical College, for 16 months from June 1979 to Oct. 1980.All the scans were obtained with the Hitachi CT-H2 scanner and the scans were repeated following intravenous injection of high dose of contrast media(roughly 1.8cc per kg body weight of 60% Conray). We have reviewed the CTscans of 310 patients got acute head injury in order to assess the location of brain lesions, the relationshipbetween the CT scans of 310 patients got acute head injury in order to assess the location of brain lesions, the relationship between the CT densities of hematomas and their stage, the shape mass effect of the extra-axialhematomas, and the effect of contrast enhancement. The resuls were as follows; 1. Of all 310 cases of the headinjuries, epidural hematoma was 13.5%, subdural hematoma was 8.7%, subdural hygroma was 10%, cerebral contusion was 39%. hydrocephalus and atrophy was 3.9% and negative finding was 24.9%. 2. The extra-axial hematoma waslocated on the right side in 49.3% and the left side in 39.1% and bilaterally in 11.6%. Therfore unilateral lesion was much more than bilateral one. 3. The extra-axial hematoma was getting decreased in density as time gone by. 4. The shape of epidural hematoma was biconvex in 88.1% and planoconvex in 11.9%. 5. The shape of subdural hematoma was crescent in 88.9% and biconvex in 11.9% in chronic stage. 6. The mass effect of extra-axial hematoma was getting slowly decreased as time gone by. 7. The extra-axial hematoma was enhanced by the contrast media in allacute, subacute and chronic stages as well as in the cerebral contusion, but there was a tedency that the contrast enhancement of hematoma was getting increased as time gone by.

Decentralization to local governments and amending of Health center Law are to promote the efforts of health planning at the level of local agencies. In the health facility planning, it is important to take into account that what to be built, where to be located, how far should be service area and so forth, because health facilities are immovable, and require capital as well as personnel and consumable supplies. The aim of our study, answering to the question of 'where to be located?`, is to determine the best location of urban health sub-center. At the local level, planning is the matter of finding the best location of specific facility, in relation to population needs. We confine the accessibility, which is basic to location planning, to geographic one. Location-Allocation Model is used to solve the problem where the location is to maximize geographic accessibility. To minimize the weighted travel distance, objective function, Rk= aijwidij is used. Distances are measured indirectly by map measure-meter with l:25,000 Suwon map, and each potential sites, 10 administrative Dongs in Kwonson Gu, Suwon, are weighted by each number of households, total population, maternal age group, child age group, old age group, Relief for the livelihood, and population/primary health clinics. we find that Kuwoon-Dong, Seodun-Dong, Seryu3-Dong, according the descending orders, are best sites which can minimize the weighted distance, and conclude that it is reasonable to determine the location of urban health sub-center among those sites.

OBJECTIVE: To evaluate the degree of streptococcal colonization in Korean pregnant women. METHODS: The study comprised of 153 singleton pregnant women who visited Severance Hospital for delivery, and their neonates. Specimens for GBS culture were collected by a sterile cotton swab from lower vagina and cervix of pregnant women, and from ear canal and throat of neonates. They were first cultured for 48 hours in Todd-Hewitt broth and then subcultured onto Tryptose blood agar plates(Difco). Group B streptococci were confirmed by the presence of beta-hemolysis and a positive reaction with Phadebact group B Streptococci reagent(Karo Biodiagnostics AB, Huddinge, Sweden). RESULTS: The prevalence of positive cultures in pregnant women and neonates were 2.61%(4/153) and 0%(0/4), respectively. In the study population there was a case of suspicious group B streptococcual sepsis in an infant whose mother was colonized. CONCLUSIONS: In our study the GBS colonization rate in Korean pregnant women was significantly lower than that of other countries. The reason for this difference may be associated with a racial differences, or social factors such as socio-economic status or a life style.

PURPOSE: Puberty is a rapid changing periods of body composition and endocrine system. Already leptin was known to be closely related to body composition and was known to change according to Tanner stage. Ghrelin, a natural GH secretagogue, was also known to be related with weight change, fat utilization, insulin secretion, and influenced by sex steroid. But the relationship between ghrelin and other parameter according to pubertal development is not established yet. METHODS: Cross-sectional study of 101 peripubertal children (54 males and 47 females) aged 8.5 to 17.0 years. We examined body composition (free fat mass, fat mass, % body fat) by bioelectric impendence measurements. Total ghrelin, leptin, insulin was measured by radioimmunoassay (RIA). Relationship between ghrelin, leptin, insulin and body composition data was analysed according to Tanner stage controlling gender using SPSS ver 11.0. RESULTS: Ghrelin concentration is only correlated with Tanner stage (r=-0.21, P<0.05) and GIR (r=0.29, P<0.01). When we divided subjects by sex, even though there was no difference of ghrelin level between both sex, only male is correlated with Tanner stage (r=-0.28, P<0.05) and GIR (r=0.36, P<0.01). There was no difference of ghrelin level between each Tanner stage and no correlation was observed with other body composition and endocrine parameter including leptin. CONCLUSION: These data suggest that Ghrelin levels decrease during puberty at least in boys as pubertal development proceeds but it is minimal. During puberty, ghrelin levels are stable. Ghrelin may have no relationship with other pubertal change. The relation of ghrelin and insulin sensitivity need to be further investigated.
