A survey of the biting midges of the Genus Culicoides was conducted by a joint effort of numerous U.S. and Korean personnel throughout South Korea for seven years from 1965 through 1973 (except 1968, 1971) using New Jersey light traps set up at fifty-nine (59) different locations, to find out the seasonal succession and geographical distribution of the said insects both on an individual species basis and as a whole, and to evaluate the medical significance and epidemiology of these insects. This provides some of the basic knowledge needed for prevention of filarial and virus transmission of diseases owing to these insects. As a result the following results were obtained: Sixteen (16) species hitherto unrecorded were added to the fauna of biting midges known from South Korea. Together with the already recorded fourteen (14) species, this makes the total number of species of these insects in South Korea thirty (30).Through the monthly tabulation of the collected specimens it was possible to find out the general seasonal succession of these insects as well as their sex ratio. Based on the data obtained the geographical distributions of the biting midges of the Genus Culicoides so far recorded in Korea were classified into the following four (4) types: The species which are very widely spread throughout south Korea. The species which are spread in central South Korea and supposed to occur in North Korea. The species which were collected from coastal areas and southern island. The species which were collected from Cheju-do.

The femoral neck fracture in children is rare and occurred by severe trauma and the treatment method and prognosis are different from adult, and it is difficult to treat due to frequent complication, which is so called “unsolved fracture”. Twelve cases of children's femoral neck fracture were treated at Chon Buk National University Hospital from July, 1981 to May, 1988 were analysed clinically and radiologically and following results were obtained 1. The commonest age group was between the age of 14 and 16 years and the ratio of boys and girls was 2:l. 2. The main cause of fracture was traffic accident(6 cases) and fall down was 5 cases and slip down was 1 case. 3. According to the Delbet and Colona's classification, the transcervical fracture was most common type and displaced fracture was 8 cases. 4. Associated injuries were extremity fracture(3 cases) and pelvic bone fracture(2 cases) and head injury(2 cases), etc. 5. Seven cases were treated by open reduction and internal fixation and five cases by cast immobilization after skin or skeletal traction. 6. The commonest complication was coxa vara(5 cases) and other complication was avascular necrosis of femoral head(3 cases) premature epiphyseal closure(3 cases), nonunion (2 cases). 7. According to Ratliff's assessment of results, eight cases were good result and two fair results and two poor results. 8. Secondary operation (muscle pedicle bone graft, corrective subtrochanteric valgus osteotomy) was done in three cases and showed one good result, one fair result and one poor result.

A study was made on the two cases of congenital adrenogenital syndrome. Cliteroplasty wag performed on the two cases in addition to adrenalectomy in one case. Good results were obtained following the treatment.

Additional two cases of Klinefelter's syndrome with a literatural review was presented Two cases were revealed characteristics of Klinefelter's syndrome such as small testes, hyalinization of seminiferous tubules, azoospermia, increased FSH, normal 17-ketogteroid and positive sex chromatin. One case was associated with left inguinal crytorchidism.

Simple posterior hip dislocations requiring open reduction is very few and reported approximately 3% of all posterior hip dislocations and we have little comments of the various causes preventing or blocking a concentric reduction following traumatic posterior hip dislocation. In a review of eleven cases of posterior dislocation requiring open reduction, we divided two groups, one is a failed closed reduction group, the other is a nonconcentric reduction group. A concentric reduction was prevented from an inverted limbus or an osteocartilagenous loose body from acetabulum or femoral head.

This study was conducted on 342 patients(male 157, female 185)aged 8 to 15 years old, who visited Dankook University Dental Hospital. Pre-orthodontic treatment orthopantomograms were used to assess the dental calcification stages of mandibular 3rd molar, 2nd molar, 2nd premolar and 1st premolar by 8 stages.(by Demirjian) Hand-wrist radiogrms were used to evaluate the skeletal maturity in 11 stages.(by Fishman) Following results were obtained after investigating the correlationship between dental calcification and skeletal maturity. 1. Chronologic age showed high correlation to dental calcification and skeletal maturity. 2. Dental calcification and skeletal maturity showed high correlation and no statistical difference was observed between male and female. 3. SMI stages 1 to 4 showed high statiscal significance to mandibular 2nd molar, 2nd premolar and 1st premolar. SMI stages 5 to 8 showed high stastical significance to mandibular 2nd molar, 2nd premolar. SMI stages 9 to 11 showed high statistical significance to mandibular 3rd molar.

Hyperextension injury in the thoracic spine is uncommon with only a few cases documented in the literature. The mechanism of these injuries is hyperextension combined with axial or shearing force. These types of injuries are associated with a high risk of dural tears and paraplegia. A 91-year-old female presented with acute back pain from a hyperextension injury in thoracic spine with no neurological deficit. Lumbar magnetic resonance imaging showed a intervertebral disc rupture. On day 20 of hospitalization, the herniated intervertebral disc compressed the spinal cord with incomplete paraplegia. Hyperextension injuries involving the three columns are very unstable and we recommend surgical treatment as soon as possible, not only because of the initial trauma, but a ruptured disc herniation can damage the spinal cord.
