In this study, urban dispersion model was studied to predict dispersion of Hazardous Air Pollutants(HAPs) in the complex urban terrain. To obtain a wind field data of urban terrain various models were tested and characteristics of model variables were studied. As simulate dispersion in the complex urban terrain with obtained wind field data using morphological method, characteristics of the dispersion were investigated. On the morphological method, the geometry data of building is important. However, the wind field that plays a major role in the dispersion is not affected easily by existence of building on urban terrain.

N/A Objective: To evaluate the frequency and obstetric consequences of women with uterine anomalies and correlation between obstetric consequence and congenital uterine anomalies. Materials and Methods: A retrospective study was made on 65 patients with uterine anomalies in order to evaluate the obstetric consequence at department of obstetrics and gynecology, Soonchunhyang University Hospital from January 1994 to June 1997. The diagnosis of uterine anomalies was made with hysterosalpingogram or ultrasonogram, or at the time of cesarean section. The uterine anomalies were classified according to the classification of Buttram and Gibbons and compared the pregnancy outcome for each classification. The obstetric consequences were divided into preterm delivery, premature rupture of membranes, intrauterine growth restriction, and abnormal presentation of fetus. Statistical analysis was carried out using chi-square test, the significance was defined as P < 0.05. Results: 1. The incidence of uterine anomalies accounted for 1.04% (65/6,250 deliveries). 2. The most common uterine anomalies were class III (Uterine didelphys, 47.7%). 3. We noted preterm birth rate (16.9%), premature rupture of membranes rate (20%), intrauterine growth restriction rate (9.2%) in 65 patients. 4. The rate of breech presentation was 41.5% and the mean birth weight was 2,747 gram. 5. When uterine anormalies were present, the incidence of obstetric consequences was significantly increased. Conclusion: We concluded that congenital uterine anomalies were closely related to obstetric consequences, such as preterm, breech presentation, intrauterine growth retardation.
