Chae, Jong-Moon 대한치과교정학회 발행 2005 대한치과교정학회지 Vol.35 No.6

Maxillary anterior teeth were intruded and lingually root torqued with two maxillary anterior microimplants between the lateral incisors and canines. Overerupted maxillary canines were intruded with two other microimplants between the maxillary canines and first premolars. Maxillary posterior teeth and canines were distalized, then the maxillary incisors were retracted with two maxillary posterior microimplants between the first and second molars. The mandibular anterior teeth were intruded and the mandibular posterior teeth were extruded with conventional method such as anterior bite plane, intrustion arch and Class Ⅱ elastics. The mandible moved slightly forward after the correction of deep bite and retroclination of the upper incisors. Consequently, microimplant anchorage (MIA) provided absolute anchorage for simultaneous correction of Class Ⅱ canine and molar relationships and deep overbite. 상악 측절치와 견치의 치근 사이에 식립한 microimplant를 이용하여 상악 전치의 함입과 설측으로의 치근 이동을 얻을 수가 있었으며, 상악 견치와 제1소구치의 치근 사이에 식립한 microimplant를 이용하여 과맹출된 상악 견치를 함입시켰다. 또한 상악 제1,2대구치의 치근 사이에 식립한 microimplant를 이용하여 상악 견치 및 구치의 후방 이동 및 상악 전치의 후방 견인을 시행하였다. Anterior bite plane과 intrusion arch, 그리고 Ⅱ급 고무 등과 같은 전통적인 방법을 사용하여 하악 전치의 함입 및 구치부의 정출을 얻얼 수가 잇었으며, 과개 교합 및 상악 전치의 설측 경사가 해소 되면서 하악골이 전방으로 약간 이동하였다. 이와 같이 MIA는 Ⅱ급 2류 부정교합 환자에 있어서 Ⅱ급 견치 및 구치 관계 그리고 과개교합을 동시에 해소 하는데 절대적인 고정원을 제공하였다.

Background and Objectives: Breast carcinoma is a heterogenous disease. The prognosis of this carcinoma correlates with various prognostic factors. The aim of this study was to assess the prognostic significance of expression of p53, cyclin Dl and cathepsin D protiens in association with various prognostic factors in invasive breast carcinoma. Materials and Methods: The relationship is presented between expression of p53, cyclin D1 and cathepsin D by immunohistochemistry and various established prognostic factors such as tumor size, histologic grade, lymph node status and extensive intraductal component in 55 cases of invasive breast carcinoma. Results: No significant correlations were observed between expression of p53, cyclin Dl and cathepsin D and tumor size. The expression of p53 correlated with high histologic grade. The expression of p53 and cyclin Dl correlated with lymph node metastasis. Conclusion: These results indicate that expression of p53 and cyclin Dl in invasive ductal carcinoma may be an important prognostic factor, closely related to the high histologic grade and lymph node metastasis.

This paper is to analyse electromagnetic fields on a 154kV substation system and induced voltages on the substation fence when the network is operating in a normal condition or a fault condition in which one phase is shorted with the ground wire using HIFREQ software. Also, the changing trend of scalar potential and electromagnetic fields that are changed in accordance with the value of resistivity and relative permeability of ground are showed and discussed. A finding of the study is that the scalar potential and electro-magnetic fields are raised near the tower, and the values of electric field on the comer of substation fence and at the edge of the ground grid are higher than other locations. And the trends of electric fields under normal condition and fault condition are similar to each other, the trends of magnetic fields are showed the peak value at the inflow point of current. The induced currents of substation fence have the peak value at the bottom outside of transmission line under normal condition and at the bottom of fault line under fault condition.

뇌사의 법적 의미와 장기등이식에관한법률

문채규 한국비교형사법학회 2003 비교형사법연구 Vol.5 No.2

Die jahrzentelange rechtspolitische Diskussion um die Organtransplantation bei Hirntoten wird mit dem Transplantationsgesetz vom 8. Februar 1999 vermutlich kein Ende finden. Sie begegnet eine Reihe von Rechtsfragen, deren Losung bislang noch nicht befriedigend ist: Zum einen bleibt noch immer eine wisswnschaftliche Streitfrage, ob wir den Hirntod als den Tod des Menschen anerkennen durfen, zum andern bleibt auch eine andere Frage, ob Angehorige, wenn der Hirntote die Entscheidung uber eine Organspende zu Lebzeiten noch offen ließ, diese Entschedung treffen konnen. Die bisherigen Auffassungen haben deutlich werden lassen, daß der Hirntod unterschiedlich, ja gegensetzlich gewertet wird: Fur die einen ist er ein sicheres Kriterium fur die Todesfeststellung; fur die anderen markiert er zwar einen bedeutsamen Punkt im Sterbeprozeß, doch er bedeutet noch nicht den endgultigen Todeseintritt. Auch wenn man alle rein medizinischen Argumente fur die Gleichsetzung des Hirntodes mit dem Tod des Menschen als unbestritten ansahe, blieben immer noch Fragen innerhalb des rechtlichen Bereichs offen, die geeignet sind, Zweifel an der Richtigkeit der Gleichsetzung zu begrunden. Was medizinisch machbar ist, ist nicht stets auch rechtlich vertretbar. Weiter ist problematisch, ob die Angehorigen aus eigenem Recht in die Organentnahme einwilligen konnen oder ob man sagen muß, das Personlichkeitsrecht des Hirntotes verlange, daß sie sich nach seinem mutmaßlichen Willen richten. Es spricht mehr dafur, die Angehori- genseinwilligung im letztgenannten Sinne zu verstehen, da es der Konzeption der Selbstbestimmung und -verfugung des Hirntotes am besten entspricht. Das Recht auf ein naturliches Sterben und die Gewahrleistung einer ungestorten Endphase dieses Sterbens ist, sofern der Sterbende wirklich oder vermutlich nicht zuvor in eine Organentnahme eingewilligt hat, ein integraler Teil des grundgesetzlich verburgten Lebensschutzes. Dieses Grundrecht kann niemandem genommen werden. Eine medizinwissen- schaftliche Mehrheitsmeinung kann die Reichweite der Grundrechte nicht einschranken. So durfte das Transplantationsgesetz ab dem Zeitpunkt der Unumkehr- barkeit des Sterbeprozesses nur noch eine vom Spender selbst konsentierte Organentnahme zulassen und keiner dritten Person, auch nicht einem nahen Angehorigen, das eigenen Recht einraumen, einer Organentnahme zuzu- stimmen. Die Erkenntnisumwandlung ist erforderlich. Es gilt, die Voraussetzungen dafur zu schaffen, daß die Bevolkerung optimal daruber informiert wird, was es mit der Entnahme blutfrischer Organe nach dem Hirntod auf sich hat. Erfolgreich kann auf lange Sicht nur im Verein mit einer umfassenden und ehrlichen Information fur Organspenden geworben werden.

적응 알고리즘을 이용한 DS/CDMA 간섭제거

문병현,손준일,이채욱 대구대학교 과학기술연구소 1998 科學技術硏究 Vol.5 No.2

A DS/CDMA receiver with adaptive filter has more benefit than conventional DS receiver, such as near-far problem, multiuser interference rejection and artificial jamming. Usually in the CDMA receiver, filter length is same as spreading sequence length. So the more PN sequence length, the more number of calculation is needed for convergence. Recently, partial update algorithm like SNLMS or SBNLMS is proposed to resolve this problem. But these algorithms have defect that convergence is slow because of partial updating. We propose the effective adaptive algorithm for DS/CDMA multiuser interference rejection and show the correlation between the number of block and convergence in selective coefficient update algorithm.
