Fe(C) nanocapsules were prepared by the chemical vapor condensation(CVC) process using the pyrolysis of iron pentacarbonyl $(Fe(CO)_5)$. Their characterizations were studied by means of X-ray diffraction, X-ray photoelectron spectrometer and transmission electron microscopy. The long-chained Fe(C) nanocapsules hav-ing the mean size of under 70 nm could be obtained below $1100^{\circ}C$ in different gas flow rates. The particle size of the powders was increased with increasing decomposition temperature, but it was decreased with increasing CO gas flow rate. The Fe powders produced at $500^{\circ}C$ consisted of three layers of ${\alpha}$-Fe/$Fe_3C$/amorphous phases, but it had two phase core-shell structure which consited of $Fe_3C$ phase of core and graphite of shell at $1100^{\circ}C$.

"Res iudicata"(Latin for "matter already judged") happens in principle only at person concerned and does not influence on a third party. Also, because joint litigant in the essential joint action or plaintiff․ defendant․ participation litigant in the independence person concerned participation lawsuit are the parties to a lawsuit, res iudicata reaches even in these people. Namely, that is the principle that res iudicata reaches only a person who has an opportunity submitting attack and defense method as a person concerned in litigation. Because enforcing litigation sequence on third party who don't have an opportunity that can claim and defend oneself's right is not improper in third party's viewpoint of formality guarantee as the purpose of litigation is clarification of right relation beween dispute person concerned. Consequently res iudicata does not reach to counsel, assistance participa tion or ordinary joinder mutually as well as third party of intervention. Accordingly, res iudicata that is full to legal principle of own responsibility which follows disposition principle by the person concerned has hard times relativity while res iudicata is reconciled with target of litigation that solve dispute beween person concerned in efficacy though that has public law character. But res iudicata reaches power in the third party who is the close relation with the person concerned in order to secure effectiveness of troubleshooting between the person concerned. Successors who is concluded argument, presumed successors, requisition right reversion subject from third person lawsuit charge, lawsuit secession person etc. are them. In particular, it can secure the troubleshooting effect in compliance with a judgement by doing so that successor receives pace of res iudicata in relation with counterpart after couclusion of argument. By the way, there is confrontation of opinion about that board power includes in extended successor's extent in this case though there is occasion that position of individual substantial law, that is, unique protest rights (Unique margin) that this successor can oppose against about other person's claim of right own bring. Also, when there is peculiar defense method along with extension of res iudicata, there is a problem whether executive power reaches. Hereupon, in this paper we search the confrontation and the meaning of realism · formalism referred res iudicata expansion and execution power extension when successor has the unique rights of defense regarding successors' extent after argument conclusion. Also, we wish to examine about the policy of presumed successor etc. that make as theoretical basis in formalism.

연 재배연못에서 발견된 큰물개구리밥에 R. solani AHL1에 의해 국지적으로 말라 고사하는 것을 관찰하였다. 병원균을 분리하여 형태적 특징을 조사한 결과 균사는 두께가 5−6 μm이고 둔각분지를 하고 있었으며 핵형은 다핵형이었다. 배양적 특성으로 균사생육은 25℃에서 가장 왕성하였으며 30℃에서 가장 많은 균핵이 형성되었다. 온도에 따른 병원성과 발병정도를 조사한 결과 20℃, 25℃와 30℃에서 모두 병원성이 나타났으며 발병정도는 30℃에서 가장 높게 나타났다. 병원균을 유전자 수준에서 동정하기 위해 ITS 영역을 Neighbor-Joining 방법을 이용하여 계통분류분석을 수행한 결과 R. solani로 동정되었다. 본 연구에서 분리된 R. solani AHL1은 벼잎집무늬마름병을 유발하는 병원균과 유사하여 벼에 대한 병 발생 여부는 추가적으로 연구가 필요하다. 현재 농업은 화학비료의 사용을 억제하는 추세로 녹비를 이용한 유기농업으로, 주요 녹비인 Azolla 안정적인 사용을 위하여 Azolla에 발생하는 병에 대한 연구가 더 이루어져야 된다고 사료된다.

Background: This study was designed to compare the effect of dexmedetomidine and remifentanil used in anesthetic induction on hemodynamic change after direct laryngoscopy and tracheal intubation. Methods: A total of 90 ASA class 1 or 2 patients were randomly assigned to one of 3 groups to receive one of the following treatments in a double-blind manner: normal saline (Group C, n = 30), dexmedetomidine 1 μg/kg (Group D, n = 30), remifentanil 1 μg/kg (Group R, n= 30). Anesthesia was induced with propofol 2 mg/kg and rocuronium 0.6 mg/kg and maintained with 2 vol% sevoflurane and 50% nitrous oxide in oxygen. In group D, dexmedetomidine 1 μg/kg was infused for 10 min before tracheal intubation. Patients in group R was received 1 μg/kg of remifentanil 1 minute before tracheal intubation. The systolic blood pressure, diastolic blood pressure and heart rate were recorded from entrance to operation room to 5 min after tracheal intubation. Results: The percent increase in systolic and diastolic blood pressure due to tracheal intubation in group D and R were significantly lower than that of group C (P < 0.05). The heart rate 1 min after tracheal intubation was lower in groups R and D than in the group C (P < 0.05). Conclusions: In healthy normotensive patients, the use of dexmedetomidine during anesthetic induction suppressed a decrease in blood pressure due to anesthetic induction and blunted the hemodynamic responses to endotracheal intubation.

The purpose of this study was to review the clinical features, histological types and the mode of treatment of malignant gynecologic tumors. Retrospective reviews of the medical recordings for 75 cases with malignant gynecologic tumors in department of Obstetrics and Gynecology, Kuri hospital Hanyang University from July. 1, 1995 to Jun. 30. 2000. We analysed clinical characteristics, stage, histopathologic type and treatment modality. Of 75 cases, 44 cases were carcinoma of the uterine cervix, 21 cases were ovarian cancer and 10 cases were uterine cancer. The mean age of cervix cancer is 53.3 years, ovarian cancer is 50.9 years and uterine cancer is 49.5 years old. The main treatment modality of cervix and uterine cancer were surgery followed radiotherapy and ovary cancer was surgery plus adjuvant chemotherapy. However, as the number of patients were small in our study, further study with large number of patients are warranted.
