One hundred fifty-seven patients wha underwent radical hysterectomy and pelvic lymphadenectomy for FIGO stage IB and IIA carcinoma of the cervix between February l975 and May 1987 were retros-pectively analysed to identify specific risk factors associsted with treatment failures. Prognostic factors inciuded clinical stage, histologic cell type, degree of differentiation, size of primary tumor, depth of stromal invasian, lymph-vaseular space invasion, and lymph node metastasis. Treatment results were evaluated according to the recurrence rate and 2-year absolute recurrence-free survival(NED) rate by the prognostie faetors and treatment modalities. Patients with lymph node me tases had a significantly higher incidence of bulky primary(-> 4cm), depth of stromal invasion(> 60% thickness), and lymph-vascular invasion(P<0.005). There was significant difference in the recurrence rate and 2-year, NED rate between cervical carcinoma stage IB and I1A(P <0.005). The pat,ients who had bulky primary tum~or(>4cm) and/or depth of stromal invasion (>60% thickness) had a higher recurrence and lower 2-year NKD rate(P<0.025, P<0.005), Unfortunately, it was not possible to demonstrate that these detrimentel effects could be overeorne by postoperetive radiation. When adjoined for these risk group, traditionally reported poor prognostic factors such as nodal metatasis, cell type and differentiation, lyrnphi-vascular mvasion assume less importance in our studies. In this study, prognosis is most inf1ueneed by clinical stage, depth of stromal invasion, and size of primary tumor,

Ultrasonography is most commonly utillized diagnostic tool in obstetric and gynecology for the evaluation ofpatient with a pelvic mass or pregancy. For it is characterized by no radiation hazard, noninvasive examinationand high diagnoastic accuracy. Also it affords an accurate assessment of the presence, size, location and internalconsistency of a pelvic mass. The recent availability and improved resolution of realtime scanning have afforded amore flexible and complete approach to evaluation of normal and abnormal structures in the pelvis. We analyzedultrasonographic findings in 154 pathologically proven cases of pelvic mass examined at Korea General hospitalfrom Jan. 1983 to Apr. 1984. The results were as follows; 1. The age distribution was from 12 years to 66 yearsand the majority of patients were between the ages of 21 and 50 yeasrs (91.4%). 2. The incidence of pelvic masswas 27.9% in uterine leiomyoma, 22.7% in ovarian cyst, 13.0% in addenomyosis and 8.4% in serous cystadenoma. 3. Mild to moderately echogenic nodular uterine enlargement with some cystic change(81.5%) of leiomyoma and multiplesmall vesicular pattern of intrauterine contents with uterine enlargement of Homole were the most common ultrasonographic findings. The location and type of leiomyoma were most common in the fundus and body (95.3%), and intramural myoma(53.5%). The most frequent finding of ovarian teratoma was cystic mass with echogenic focus(41.7%) but the echogenic appearance of the lesions was extremely variable. The ultrasonographic findings ofectopic pregnancy were cystic or complelx adnexal mass(80.0%), with or without fluid in cul-de-sac and deviationof uterus by adenxal mass. 4. Accuracy of ultrasonography in detemining the overall correct diagnosis of thepelvic masses compared with proven diagnosis was approximately 61.7%. The diagnostic accuracy was 90.7% inluterine leiomyoma, 100% in H-mole nad 80.0% in ectopic pregnancy.

OBJECTIVE: This study was performed to evaluate the effects of mutiple indications and age on the likelihood of finding cervical lesion in large loop excision of transformation zone(LLETZ). METHOD: We reviewed the medical records of 471 evaluable LLETZ of cervix for cervical neoplasia at the Yonsei University College of Medicine, from April 1996 to August l998. The indications for the LLETZ were grouped as being for treatment(biopsy-proven disease)(indication A), significant discrepancy among cytologic and histologic results(indication B), unsatisfactory colposcopic finding(transformation zone not fully visualized)(indication C), possible microinva- sion(indication D), and combinations of the above. RESULTS: The prevalence rates of cervical lesion in performed LLETZ for indication A alone, for indication B alone, for a combination of indication A and C, for a combination B and C, and for indication D alone were 85.7%, 56.5%, 82.3%, 42.6%, 95%, respectively. The data were then reanalyzed to determine the likelihood of finding high-grade disease on LLETZ specimen. Overall, those with preoperative high-grade cytologic or histologic characteristics were much more likely to have high grade disease(78.1%) than were those with preoperative low-grade cytologic or histologic characteristics(27.2%)(p<0.001). The influence of age on the likelihood of identifying diasease on the LLETZ is undertermined. CONCLUSION: Neither age nor the preoperative grade of disease are good discriminators of the likelihood that disease will be found on a LLETZ specimen, However, patients with preoperative high-grade disease are much more likely than those with preoperative low-grade disease to have high-grade dysplasia or invasive cancer on LLETZ.

Corneal epithelial wound healing is followed by cellular migration and proliferation. Hyaluronic acid and EGF have been used to promote corneal wound healing. We investigated the effect and action mechanism of Hyaluronic acid and EGF using agarose explant method and organ culture. In the agarose explant method, we studied the promoting effect of different concentration of Hyaluronic acid and EGF, combined effects and mitotic inhibitory effect of colchicine on cultured corneal epithelial cells in the rabbit. And we studied the result of the organ culture with same agents using round epithelial defect by the trephine. Hyaluronic acid and EGF showed significant promoting effect on corneal wound healing, and the combined effect was also significant. The effect of Hyaluronic acid and EGF was inhibited in colchicine combined culture. Therefore, the effect of hyaluronic acid and EGF is seemed to be on the cell proliferation rather than cell motility.

The factors determining refractory power are axial length, corneal power and lens power. The author investigated the correlation between axial length and refractory power by research for growing process of axial length in Korean children. The mean values of axial length are obtained by ultrasonography (A-scan) after cycloplegic refraction. The subjects of study were 245 children, 483 eyes, from 4 to 14 years old. The study revealed that axial length increased by aging and axial length change to refractory power tends to lengthen with increasing degrees of myopia, shorten with increasing degrees of hyperopia. Statistical analysis of the research show that the phenomenon is presented remarkably in patients of over-4 diopter.

PURPOSE: The purpose of this study was to develop a system dynamics model for adolescent obesity in Korea that could be used for obesity policy analysis. METHODS: On the basis of the casual loop diagram, a model was developed by converting to stock and flow diagram. The Vensim DSS 5.0 program was used in the model development. We simulated method of moments to the calibration of this model with data from The Korea Youth Risk Behavior Web-based Survey 2005 to 2013. We ran the scenario simulation. RESULTS: This model can be used to understand the current adolescent obesity rate, predict the future obesity rate, and be utilized as a tool for controlling the risk factors. The results of the model simulation match well with the data. It was identified that a proper model, able to predict obesity probability, was established. CONCLUSION: These results of stock and flow diagram modeling in adolescent obesity can be helpful in development of obesity by policy planners and other stakeholders to better anticipate the multiple effects of interventions in both the short and the long term. In the future we suggest the development of an expanded model based on this adolescent obesity model.
