남경우,예윤해 경희대학교 레이저공학연구소 2000 레이저공학 Vol.11 No.-

The configuration for a new fiber Fabry-Perot(FFP) interference filter is analyzed to correct the previous analysis. In the previous analysis the calculations were based on the convolution of the transfer function with optical beam, but it is replaced by the multiplication of the two. With the Gaussian beam approximation of the guiding mode in the step-index single mode fiber and a 15㎛-long planar-concave fiber cavity as in the previous analysis, it was confirmed that the coupling loss could be maintained below 0.5% even with mirror tilt, lateral offset and curvature radius of less than 0.4 degrees, 35㎛ and 20㎛ respectively.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

Background: Vitronectin is one of major cell- adhesive glycoprotein in mammalian serum and plasma ; the other is fibronectin. It is a mixture of 65 and 75kDa protein in plasma which promotes spreading of a variety of cultured cells ,inhibits the cytotoxicity of membrane attacks complex C5b-7 and modulates thrombin-antithrombin III activity. Human plasma and serum contain 10-40mg of vitronectin per 100ml,but only a few mg or less of vitronectin can be isolated with a 0.5-20% recovery efficiency through very long processes or with expensive,commercially available monoclonal antibody. In this study, we purified the vitronectin from human plasma and produced anti-vitronectin polyclonal antibody using purified vitronectin. Methods: Vitronectin was purified from the human plasma by heparin-sepharose column and its efficacy was measured by cell spreading assay. Anti-vitronectin polyclonal antibody produced and confirmed by ELISA and immunoblotting. Results: This procedures produced about 0.8mg vitronectin from 100ml human plasma within 2 days. 1) Purified vitronectin promoted spreading of HepG2 hepatoma cells on substrates with a half maximal activity at 0.lug/ml. 2) In SDS-PAGE analysis of purified protein, 2 bands were found and their molecular weights were 75kDa and 65kDa,respectively. 3) The immunoblotting assay showed that the bands of molecular were same site as SDSPAGE analysis. Conclusion: Simple,rapid purified vitronectin by heparin-sepharose column and anti-vitronectin antibody may facilitate the elucidation of vitronectin function and action mechanism in human body.

UML is able to visualize and specialize the output of the system center of the software, and able to connect to various languages and is constructed by engineering/re-engineering. Also, UML is a standard Modeling Language that aims at the documentation. Recently Web Application System is quickly popular and gigantic, it's possible to do modeling using UML which is the method of Object-Oriented analysis and design and simplify the complex developing course of software. In this paper, we suggest the 『Post Seminar System』 model for instance Object-Oriented Web Application which can increase the efficiency of businesses through of exchanging information with members. We constitute web application by separating it into 3 steps such as View class which takes full charge of Screen Presentation, controller which plays the role of connecting ring and divergence of View class and Model class, and Model class that takes charge in the gear with the Application Logic and DB applying MVC model which has considerable merit in developing and maintaining the web application.

The purpose of the study was to develop the curriculum of medical welfare based on the perspectives from the disciplines of medicine, nursing and social welfare. The final goal of the study is to enhance the clinical competency of the graduates to effectively deal with the situations required for skills and approaches from both disciplines. The study has been designed to conduct in 3 phases; the first phase to explore the potential employment for the graduates of medical welfare by describing the specific areas which their clinical competency would fit in, the second phase to identify the level of recognition made by students regarding the medical welfare program, the third phase to develop the curriculum of medical welfare according to the student classification. In the first phase of the study, total of 115 questionnaires were sent to the institutions and hospitals specifically selected for their relevancy to the medical welfare program and 53 responses (reply rate 46.1%) were included in the analysis. Most respondents (87%) were familiar to the definition of medical welfare and 77.4% reported that they believe this program would be helpful to do their job. More than 90% of respondents assessed the future of the medical welfare program is rather good. In the second phase of the study, 301 students from the first and second year of Soonchunhyang University received a questionnaire regarding the medical welfare program that has been recently listed in their option for secondary major. Thirty percent of the respondents were aware of the program, and 65% expressed their interests in this program. Majority of the students (86%) considered this program would be helpful to find a job after their graduation, assessing the future of the program as promising. Most respondents (83%) were willing to refer this program to their family and friends. In the third phase, the specific curriculums of medical welfare program were developed according to the background of the potential participants. The first module is for those from social welfare discipline (14 subjects, 35 credits), the second is for those in medicine and nursing disciplines (14 subjects, 40 credits), and the third module is for those with other major (15 subjects, 41 credits). At the completion of each module, the students are allowed to take the exam for Advanced certificate of care worker. The study findings confirmed the need to develop the new approach combined in medicine and social welfare to accomplish the required role of social welfare related to the medical situation. Further studies would be required to evaluate the pilot application of each curriculum module of the medical welfare program as an evidence of practice-oriented education in university setting.

목적 : Rat2 섬유모세포에서 α-quartz에 의해 유도된 NOS의 조절기전을 알아보기 위하여 본 연구가시도 되었다. 방법 : Rat2 세포에 있어서 α-quartz 자극에 의한 NO와 H₂O₂의 분비 및 iNOS의 발현을 관찰하였고, iNOS 억제제인 L-NIL과 H₂O₂ 억제제인Catalase를 전처리하고 마찬가지로 NO와 H₂O₂분비 그리고 iNOS의 단백발현 정도를 western blot-ting을 이용하여 관찰하였다. 결과 : o-quartz는 Rat2 세포에서 iNOS에 의한NO와 H₂O₂의 분비를 유도하였다. L-NIL은 R3t2세포에서 D-quartz에 의한 H₂O₂의 분비와 iNOS발현을 완전히 억제하였다. Catalase로 전처리 하였을 때 o-quartz로 유도된 iNOS에 의하여 생산증가된 H2Oa가 iNOS를 억제하는 autoinhibitorypathway가 차단되어 결과적으로 H₂O₂의 분비와 iNOS의 발현이 증가하였다. 결론 : Rat2 세포에서 α-quartz에 의하여 유도된iNOS는 H₂O₂의 분비를 촉진하고 이 H₂O₂는 iNOS기능을 조절하는 자가조절기전에 중요한 역할을 하는 것으로 생각된다. Objectives : This study was performed in order to investigate the molecular mechanism regulating nitric oxide synthase (NOS) induced by α-quartz in Rat2 fibroblast. Methods : α-quartz-induced nitric Oxide (NO) anti H₂O₂ formation anti α-quarts-induced iNOS protein expression in Rat2 fibroblast were monitored. With iNOS inhibitor (L-N6- (1-iminoethyl) lysine hydrochloride, L-NIL) or antioxidant (catalase), we observed NO and H₂O₂ formation and iNOS protein expression in Rat2 fibroblast stimulated with α-quartz. Results : α-quartz stimulated iNOS-induced NO and H₂O₂ formation in Rat2 fibroblast. L-NIL inhibited H₂O₂ formation and iNOS protein expression by α-quartz in Rat2 fibroblast. Pretreatment with catalase blocked the autoinhibitory pathway of iNOS by iNOS-induced H₂O₂ therefore H₂O₂ and NO production and iNOS protein expression were increased in Rat2 fibrobalst stimulated with α-quartz Conclusion : α-quartz-induced iNOS Stimulated H₂O₂ formation in Rat2 fibroblast. INOS-induced H₂O₂ by α-quartz plays an important role in the autoinhibition pathway for regulating the iNOS function in Rat2 fibroblast

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.
