The author have performed and epidemiological study on the accidental deaths at industry from 1970 to 1975, in order to seek for the preventive measures of industrial accident with the understanding of its cause and characteristics of the accident deaths. The obtained results were as follows : 1. Total number of deaths for 6 years were 361 (350 males, 11 females) and the mean death rate was 33.8 per 100,000 industrial workers during 6 years. by the highest as 52.9 was in 1974 and the lowest as 13.7 in 1970. By the industry group., the death rate of Electricity, Gas and Water was 149.3, Construction 83.9 and the lowest was Manufacturing as 18.3. 2. Standardized mortality rate of the cases by the age group showed that 20-29 years old group was 43.0, 40-49 years old group 38.1, 30-39 years old group 32.0, and the lowest as 17.9 was under 19 years old group. 3. The cumulative percentage of the cases by years of service showed that under 6 months was 60.4%, under 1 year 72.9%, under 2 years 83.1%. 4. By the month of occurrence, the highest was 15.8% which occurred in August and the lowest was 5.8% in February. The highest as 19.1% was on Friday and the lowest as 11.9% on Monday by the day of a week. 5. By the causes of accident, car accidents was 28.3%, fall accidents 19.1%, accidents by a crash 9.1% in that order. By the location of injury, head was 44.6%, multiple injuries 33.0%, chest 10.5%, and back was the lowest as 1.9% was on Friday and the lowest as 11.9%. The distribution of the cases by nature of injury showed that cerebral contusion and hemorrhage was 39.4%, fracture and dislocation 33.2%, asphyxia 8.0% in that order. 6. The cumulative percentage of the cases by the duration from injury to death showed that the injuried day was 74.2%, within 3 days after injury 88.5%, within 7 days 96.1%. Therefore most of the cases were occurred within 7 days after injury. 7. By the daily mean wages, most of the cases as 91.7% were under 2,000won, and more 4,000won was 1.6% merely.

The authors attempted to examine the distribution of S-100 protein in the human fetal skin. Immunohistochemical staining(ABC rnethod) using anti-S-100 antibodies was carried out on skin specimens taken from 11 human fetuses ranging from 9 weeks to 27 weeks of estimated gestational age. At 9 weeks of estimated gestational age, the embryonic epidermis consisted of three cell layers,' the basal layer, intermediate layer and periderm, all of them being stained for S-100 protein. But after 18 weeks, the basal layer changed to be negative. Granular and cornified layer's, beginning their development at 22 weeks, were not stained for S-100 protein. Hair germ of 12 week-fetuses was recognized unstained as a bulge of basal cells. In fully differentiated structural components of the hair follicle after 18 weeks, the outer root sheath only was stained for S-100 protein whereas the inner root sheath, hair matrix cells and sebaceous glands were unstained. Eccrine gland germs developed at 12 weeks of embryonic life as undulation of the basal layer and were not, stained. And at 22 weeks, the secretory portion of the eccrine glands were formed in the dermis and stained for S-100 protein. Our present study suggests that the expression of S-100 protein can undergo considerable changes during ernbryonic differentiation in the epidermis and epidermal appendages.

The DNA ploidy using fresh tissues from 304 cervial cancer were analyzed by flow cytometry in order to evaluate the correlation between DNA ploidy patterns and prognostic factors of uterine cervical cancer. There were l67 diploid cases(55%) and 137 aneuploid(45%). No significant correlation was noted in stage, age and lymph node metastases between diploid and aneuploid tumor. But S-phase fraction and DNA index were higher slightly in cases of lymph node metastases cornpaired to non-metastases. This results suggest that the DNA ploidy cannot be used as an independent prognostic fac- tor, but further evaluation will be needed in order to conclude definite relationship between prognoseic factor and S-phase fraction or DNA index.

The purpose of the survey was to identify the degree and the relationship of sexual knowledge, sexual attitude. This information will provide useful data for a more systematic, desirable, and practical sex education. The data was collected from 187 first grade schoolchildren(95 boys and 92 girls) of two Junior high school in Chun-nam area. The data was gathered by questionnaire from Oct. 1 to 15, 1996. The questionnaire was modified by authors using the questionnaire developed by You-Jeong, Han(1996). Data was analyzed by using the statistical computer package, SAS to manipulate the data long with percentages, means, standard deviation, t-test, chi2-test, GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows : 1. Sex related knowledge. - The mean score of sex related knowledges showed significant differences between boys and girls(boys ; 22.3, girls ; 21.0, p<0.025), and in the area of pregnancy & delivery(boy ; 9.4, girls ; 7.9, P<0.000) showed significant difference between boys and girls, but in the area of physical differences of the others sex(boys ; 12.9, girls ; 13.1, p<0.551) showed no significant difference between boys and girls. 2. Sex related attitudes. - The mean score of sex related attitudes showed significant difference between boys and girls(boys ; 56.7, girls : 60.5, p<0.002) and in the area of psychological difference the other sex(boys : 28.9, girls : 32.5, p<0.000), but in the areas of form of friendship with the other sex(boys : 11.5, girls : 11.2, p<0.335), sexual delinquency & its prevention(boys : 16.3, girls : 16.9, p<0.171) showed no significant difference between boys and girls. 3. The relationships between sex related knowledges and sex related attitudes. - Those who had higher sex related knowledges showed more positive attitudes towards sex, and showed no statistical significance(r=0.08, p<0.286). 4. Differences of the sex related knowledges according to general characteristics. - The students had disease experience, health interest and more school performance had higher knowledge scores about sex. 5. Differences of the sex related attitudes according to general characteristics. - Those who were in high school performance had higher attitude scores about sex as well.. From the result of the study, it is recommended to develop systematic sex education through formal school education according to age.

The anatomic and physiologic changes of the anopthalmic orbit affect cosmetic appearance of the patient and function of the socket and the prosthesis. During the past three years, the authors studied 13 cases of dermis-fat graft and 27 cases of posterior Tenon's capsule suturing with a plastic implant, and compared the post'operative effects of the two procedures. Dermis-fat graft produced good fornix formation with no remarkable fat atrophy after both primary and secondary proceddure. Posterior Tenon's capsule suture technique showes good effect to keep implant from migration or extrusion. Size of the plastic implant and fixation of the extraocular muscles were important factors also for good cosmesis and implant motility. There revealed no significant difference between the two procedures in EOM motility, enophthalmos, deep superior sulcus deformity, implant migration or prolapse etc.

Ectopic pregnancies are unsuccessful pregnancies that result from implantation of fertilized ovum occurring inan aberrant area. Aside from an emergency case, the early diagnosis of ectopic pregnancy is very difficultparticularly in a case with insidious onset and mild clinical manifestations. Early diagnosis not only reduces thedanger, but also simplifies the management of ectopic pregnancy. Ultrasonography has been an indispensablediagnostic tool in obstetrics and Gynecology. In the authors' experience, clinical suspected ectopic pregnancy wasone of the common indications for performing ultrasonography. Since Kobayashi et al. reported the appearances ofextopic preganancy utilizing bistable B-scan ultrasonography, the ultrasonic findings of ectopic pregnancy havebeen reported by many authors. But, its accuracy and reliablity in the diagnosis of ectopic pregancy are stillopen to controversy. The authors studied 65 cases of clinically suspected ectopic pregnancy with Picker 80 L grayscale ultrasonography from Aug. 1982 to Jun. 1983. There were 29 confirmed cases, of which 15 were proved to haveextopic pregnancy and 14 were proved to have disease other than ectopic pregnancy by surgical andhistopathological study or by laparoscopy and histopatholoigcal study or by laparoscopy and follow up study. 29confirmed cases were reviewed. The resuls were as follows; 1. Among 15 ectopic pregnancies, there were 12ampullary pregnancies, 2 isthmic pregnancies and 1 interstitial pregancy. Among 14 cases of no ectopic pregnancy,there were 5 intrauterine pregnancies, 3 myoma uteri, 2 P.I.D., and 1 case of dermoid cyst, cystic teratoma,h-mole and tubal hematoma due to previous tubal ligation, respectively. 2. The age distribution of ectopicpregnancy was from 22 to 41 years. The common clinical manifestations of extopic pregnancy were lower abdominalpain (73.3%), vaginal spotting or bleeding (73.3%) and amenorrhea(66.7%). 3. Positive results of urine immunologicpregnancy test was 28.6% in ectopic pregnancy. 4. Ultrasonic findings of ectopic preganncy were as follows; 1) Nointrauterine gestational sac was observed in all cases except 1 interstitial pregnancy. Intrauterine fluidcollection was observed in 3 cases. Uterine displacement was observed in 10 cases. 2) Among 5 cases of rupturedtubal pregnancy, we observed predominantly cystic adnexal mass in 3 cases, mixed echogenic adnexal mass in 2cases, and cul-de-sac fluid in all cases. Among 9 cases of unruptured tubal pregnancy, we observed predominantlycystic adnexal mass in 2 cases, mixed echogenic adnexal mass in 7 cases, and cul-de- sac fluid in 3 cases. 3) Anechodense ring like structure was observed outside the uterus in 9 cases of tubal pregnancy. 4) In the case ofinterstitial pregnancy, eccentrically located gestational sac with overlying thin myometrium was observed withinthe uterus. 5) Fetal heart activity was noted outside the uterus with real time scanning in only 1 case of ectoicpregnancy. 5. Of 19 sonographically ectopic pregnancies, a correct positive ultrasonic diagnosis was made n 14cases (73.7%). Of 29 confirmed cases, overall diagnostic accuracy of ultrasound was 79.3%. 6. By demonstrationintrauterine pregnancy or disease other than ectopic pregnancy such as myoma uteri, homole or ovarian cyst,ectopic pregnancy was ultrasonically excluded in 10 cases. Among above 10 cases, 1 case of ultasonically bilateralovarian cyst was proved to have ruptured tubal pregnancy combined with ovarian cyst. The accuracy of ultrasonicexclusion of ectopic pregnancy was 90%. In the authors'experience, ultrasonography was very helpful in theexclusion of extopic pregnancy.
