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.

In order to reduce a depth and slope of edge of ablation, the technique using 2 or 3 ablaiton zones has been applied to excimer laser photorefracitve keratectomy (PRK) for high myopic patients. In this study, excimer PRK using 2 zones (5.0mm; 100%, 6.0mm; 70%) or 3 zone (5.0mm; 100%, 5.5mm; 70%, 6.0mm; 50%) were used to each 10 patients having a range of refractive power between -8D and -9.5D randomly and divided into group 1 and group 2, respectively. corneal epithelial healing was delayed in group 2 comparaed to group 1 and the diference of that between group 1 and group 2 were statistical significant (P<0.05). However, the difference of spherical equivalent between group 1 and group 2 was not statistically significant at each follow-up (p>0.05). Uncorrected visual acuities of 20/40 or better were achieved in all patients of both groups at the last postoperrative visit (mean+/-SD, 22+/-3.4 weeks). Spherical equivalent less than 1.0 diopter was achieved in 60% of group 1 and 80% of group 2. As a complication 3 eyes (30%) in group 1 and 1 eye (10%) in group 2 lost 2 lines of best corrected visual acuity and thee was no statistically significant difference in both corneal haziness and patients' complaints between group 1 and group 2. With these results we could find a similar clinical results between excimer PRK using 2 zones and 3 zones by 6 months.
