목적 : 성별 (sex)에 따른 태아의 차이는 고대로부터 현재에 이르기까지 많은 관심의 대상이 되어왔다. 본 연구는 선형 (linear) 및 비선형적인 (non-linear)분석 방법을 이용하여 태아심박동 (FHR)과 신생아 예후와 관련된 제 변수 등을 분석해 봄으로써 성별에 따른 태아의 행동습성의 차이를 알아보고자 시도되었다. 연구 방법 : 분만 전, 30~42주 사이에 nonstress test (NST)를 시행한 정상산모 중 분만후 태아의 성별을 Objective : The differences between two fetal sexes have been a matter of great concern from ancient times to present day. This study was initiated to research the varying fetal behaviors which would differ according to the fetal sex. Methods : With every

The Purpose of this study is to analyze the energy saving effect through green remodeling of deteriorated detached house in order to effectively reduce greenhouse gas in the building sector. In order to predict the energy saving effect through green remodeling of deteriorated detached house, the current status of detached house was surveyed in Nam-gu, Busan, and among them, Munhyeon-dong, which has the largest number of detached house, was selected as the target area. A standard model of an deteriorated detached house was selected by examining the total floor area, building area, wall material, roof material and shape, and u-value of the detached house. The heating and cooling energy according to the single element change of the passive system of the building was analyzed through the energy simulation Design Builder for the selected detached house standard model. In addition, the effect of green remodeling was analyzed through the primary energy consumption per unit area per year derived by improving the passive system and the active system, and the green building conversion was evaluated based on the result. In addition, the amount energy savings in the target area was predicted through the green remodeling effect of the derived standard model.

N/A Objective: Implantation is a complex process between developing embryo and maternal endometrium, especially decidua. Decidua is a specialized endometrium during pregnancy and decidua basalis is the real implantation site infiltrated directly by trophoblast cells. The decidua parietalis lines the uterine cavity away from the implantation site, not real implantation site. TGF- β1 and TGF-β2 have known as multipotential cytokines and expression of TGF- p and TGF-/3. increased in decidua during pregnancy than secretory phase of endometrium. However, there is little known about their expression in decidua parietalis, compared with decidua basalis. The purpose of this study was to compare the expression of TGF-β1 and TGF-β2 in the decidua basalis and decidua parietalis during early pregnancy. Methods: The early pregnant 26 samples were obtained at hysterectomy, which underwent surgery for cervical carcinoma, ovarian cancer, etc. Immunohistochemical staining of TGF- β1 and TGF-β2 was performed and staining intensity was semiquantified by using HSCORE. Results: TGF-β1 was slight]y expressed in the decidua basalis and decidua parietalis and there were no differences among them. But the expressions of TGF-β2 of stroma and glandular cells were higher in the decidua basalis than parietalis (p < 0.005). And the expressions of TGF-β2 were stronger than that of TGF-β1 in the both decidua of ear]y pregnancy (p < 0.005). Conclusion: In decidua basalis, especially stromal cells, the expression of TGF-β2 was increased than in the decidua parietalis. This suggests that TGF-β2 may play an important role in decidua basalis that is directly invasion site by embryo and can be regulated by embryonic derived local factor. TGF- 2, compared with TGF- β1, was increased in both implantation site and suggest it may regulate implantation process during early pregnancy.

Two surgically treated cases of spontaneous spinal epidural hematoma are reported. We compared the operative results between these cases, and could conclude without difficulty the early diagnosis and operation were improtant in prognosis. A patient who had endured shorter interval, around 24 hours, between the beginning of paraplegia and surgical decompression recovered earlier, not longer than one month, than the other patient who had been operated on with five days of interval. This patients did not recover well even two months after the operation.

Multiple meningiomas are a seldom encountered neoplasm. Most authors report an incidence ranging from 1 to 3% of all meningioma prior to the introduction of computerized tomography(CT). The routine use of CT has resolved diagnostic problems involved with multiple meningiomas and the incidence was 8% since the introduction of CT scan. In fact, it may be difficult to differentiate "true multiple meningioma" from simple recurrences or the special variant(forme fruste) of Von Recklinghausen's disease, and the pathogenetic factors related to true multiple meningioma is unknown, but various theroies of the etiology are explored by literature reports. We report the rare case of multiple meningiomas which diagnosed by CT scan and confirmed by operation.

Twenty six cases of borderline ovarian tumor(BOT) were treated between Jan. 1985 and Dec. 1997 at the Department of Obstetrics and Gynecology, Hanyang University. The clinical records were reviewed for all patients including histopathology, clinical features, and follow-up. The frequency of BOT was 12%(26/214) of epithelial ovarian malignancies, and patients with these tumors tend to present at a younger age(36 yrs) than those with invasive carcinomas. In terms of histologic type, mucinous type(21/26: 81%) were more prevalent than serous tumor(5/21: 19%) in this study. The positive rate of CA 125 was 20% in serous, and the positive rate of CA 19-9 was 24% in mucinous tumor. The size of mucinous was larger than that of serous tumors(17.1 cm vs 9,3 cm). Almost all of these tumor categorized as early stage(stage I: 96%), however, only one patient with serous tumor had advanced stage of disease(stage III: 4%), Therefore BOT tend to be diagnosed as earlier than invasive carcinoma. About 2/3 of patients were treated as conservative surgery(unilateral salpingooophorectomy or enuclation). Postoperative adjuvant chemotherapy was not given about half of cases(13/26). Median follow-up was 43 months and recurrent case was found only one in serous tumor. All patients in this study are still alive and free of disease except one, 5-year survival rate was 100%. But large number of study and long-term follow-up are needed to make a decision to treat and manage of BOT.
