For 63 soil series distributed in Jeju Island, natural uncultivated soils in each soil series were collected, and their physicochemical properties and their concentrations of 19 heavy metals including 8 heavy metals which are regulated by Korean Soil Environment Conservation Law, were analyzed. Moreover, the correlations between physicochemical properties and heavy metal concentrations, and between heavy metal concentrations were analyzed. The heavy metals distributed in the higher concentrations and the lower concentrations with arithmetric mean value, were Mn(730 mg/kg) and Ba(493 mg/kg), and Hg(0.146 mg/kg) and Tl(0.096 mg/kg), respectively. The correlations between pH(H2O) and heavy metals(Hg, Ni, Co, Se), between pH(NaF) and heavy metals(Hg, Ba, Se, Tl), and between organic matter content and heavy metals(Hg, Tl) were significant at the 0.01 level. From the correlations between heavy metal concentrations, there were 22 where there were significant at the 0.01 level and they showed positive correlation. Among those, the heavy metals showing the correlation higher than r=0.5, were Sb-V(0.878), Mo-Sn(0.867), Co-V(0.654), Co-Sb(0.648), Be-Sn(0.546), and Sn-Tl(0.528).

Objective: A Clinical Study of Placenta P#revia done by cesarean section and the study of preterm delivery that is major cause of premature motality even thought expected managment of placente previa. Methods: This study was evaluated for the clinical analysis on the 641 patients with placenta previa among total deliveries of 56,120 cases at the St. Mary and Holy Family hospital of Catholic University from Jan. 1,1989 to Dec.31,1997. Results: The following results were obtained: 1. The total incidence of placenta previa was 1.14%. 2. The incidence of placenta previa increases with age. 3. Placenta previa has occurred more often in multipara(60.2%) than primipara(39.8%), and placenta previa has occurred more often in women who had experienced abortion(71.8%) than women who hadnt(28.2%). 4. The types of placenta previa distributed 326 cases of totalis(50.9%), 110 cases of partialis(17.2%), 99 cases of marginal(15.4%) and 106 cases of low lying placenta(16.4%). 5. The fetal presentation distributed 557 cases of vertex(86.9%), 49 cases of breech(7.6%), 28 cases of transverse lie(4.4%). 6. The types of uterine incision included 543 cases of low sepnent transverse incision(84.7%), 46 cases of classical incision(7.2%), 9 cases of inverted T incision and 43 cases of cesarean hysterectomy(6.7%). 7. Premature delivery of placenta previa prior to completion of 37 weeks was 186 cases(29.0%) and low birth infant less than 2,500gm was 128 cases(20.0%).and perinatal mortality rate was 28.0 per 1,000. 8. During delivery, 278 cases of placenta previa(43.4%) were transfused with mean 3.6 pints. Incidence of vaginal bleeding was 49.3% of placenta previa,mean admission day until delivery was about 5 day. Conclusion: there is a strong association between advancing age and incidence of placenta previa, and then. the risk increases with parity & the number of abortion. Considering the mean volume of blood loss more than 3 pints of blood should be prepared befor delivery.

The purpose of the present experiment was to investigate the micronuclei(MN) frequency in cytokinesis-blocked(CB) cells after various doses of gamma-rays in pig (Landrace, male, 3-month-old) and so to contribute to the clarification of the question whether these species are suitable as a target organism in the test system. The frequencies of binucleated cells, and gamma-ray-induced MN in CB cells at several doses were measured in three donors. The peaks of binucleated lymphocyte formation(22%) were found at a concentration of 2% phytohaemagglutinin(PHA) and $4{\mu}g/ml$ Cytochalasin B(Cyt-B) in pig at 72 hours after incubation. Measurements performed after irradiation showed a dose-related increases in MN frequency in each of the donors studied. When analysed by linear-quadratic model the line of best fit was $y=0.0183D+0.0124D^2+0.0133$(y = number of MN/CB cells and D=irradiation dose in Gy). In conclusion, the results demonstrate that it appears feasible to use pig as target organisms in the micronucleus test to estimate the cytogenetic damage caused by ionizing radiations or, potentially, chemical compounds.

Cloacal anomalies are very rare congenital malformations with the incidence of 1/50,000-250,000 births. Hydrocolpos involves the dilatation of the vagina due to obstruction of the genital tract, leading to accumulation of secretions. Because of wide spectrum of abnormal anatomy involving urogenital and gastrointestinal systems, prenatal diagnosis is difficult. As ultrasound becomes more and more reliable, prenatal diagnosis is possible as early as in the second trimester. The presence of prenatally detected hydro (metro) colpos warrants a systematic evaluation of fetal and neonatal anatomy to rule out a large variety of possibly associated malformations or syndromes. We present a case of urogenital sinus maldevelopment which was initially presented as a fetal ascites.

Starting from April, 2003, new pre-review system has been introduced and implemented to reduce unnecessary conflict with medical care organizations caused by current retrospective claim review system and to enhance efficiency of review system. The main purpose of pre-review system is to educate doctors to contrive adequacy of medical services. This research mainly focuses on effectiveness of pre-review system`s influence on physicians` behavior changes. The analysis-participants were drawn from 1,449 clinics which implemented pre-review system, since April of 2003. The research results are as followings. First, the amount per claim has reduced by \3,154, days of visit per claim by 0.1 day, and amount per visit by \412, which were statistically significant. Second, anesthesiologists have decreased in three indicators the most, and the internists had least of changes. Third, the amount per claim and days of visit per claims has dropped significantly on physicians with less periods of practice and physicians with more ages. Fourth, the clinics without the expensive medical equipments, the city clinics showed significant decrease on days of visit per claim. Fifth, in intervention methods, the one-to-one education showed more significant decrease on amount per visit rather than information feedback by paper. In conclusion, the pre-review system have an impact on self-imposed physician behavioral change. The outcome of this research may be utilized for future extension implementation of pre-review system. Furthermore, it is showed that ability of transitions in medical services review system according to the future transition of payment system and context of health service policy.

We performed this study to determine the effect of Korean favorite teas (green tea, ginseng tea, coffee and barley tea) on jejunal crypt survival, endogenous spleen colony formation and apoptosis in jejunal crypt cells of mice irradiated with high and low dose of ${\gamma}$-radiation. Jejunal crypts were protected by pretreatment of green tea (P.O.: 1.25% water extract, for 7 days before irradiation., I.P.: 50 mg/kg of body weight, at 12 and 36 hours before irradiation, p<0.01) or ginseng (I.P.: 50 mg/kg of body weight, at 12 and 36 hours before irradiation, p<0.05). Green tea (p<0.05) or ginseng (p<0.05) administration before irradiation (I.P. at 12 and 36 hours before irradiation) resulted in an increase of t formation of endogenous spleen colony. The frequency of radiation-induced apoptosis was also reduced by pretreatment of green tea (P.O.: p<0.005, I.P.: p<0.05), pretreatment of ginseng (P.O.: p<0.005, I.P.: p<0.005) or posttreatment of ginseng (I.P.: 50 mg/kg of body weight, at 30 minutes after irradiation, p<0.05). Treatment with coffee or barley tea showed no significant modifying effects on the radiation-induced damages. These results indicated that green tea and ginseng might be a useful radioprotector, especially since it is a relatively nontoxic natural product. Further studies are needed to characterize better the promotion nature of green tea, ginseng and its components.
