김태우,고재승,장영일 대한치과교정학회 1993 대한치과교정학회지 Vol.23 No.4

This paper describes a new method to create an animal model for TMJ internal derangement in the New Zealand white rabbits and the light and electron microscopical changes of posterior attachment of them. Twenty six rabbits(2.5-3.0㎏), four normal and twenty two experimental, were used. The right disc of experimental animal was displaced anteriorly without sectioning the posterior attachment and tied to the zygomatic arch with nylon not to be reduced to the original position. The left TMJ was sham-operated to be compared with its right experimental one. Normal animals were sacrificed one day and eight weeks after experiment. Experimental animals were sacrificed one day, ten days, three weeks, five weeks and eight weeks after surgery respectively. They were fixed intravenously with 2% glutaldehyde under general anesthesia and the samples of them were processed for light and electron microscopic examination. The purpose of this experiment is to make a suitable animal model of disc displacement without reduction for studying and understanding the cellular and morphologic events in posterior attachment of TMJ including early changes which were difficult to be observed in human TMJs. The results of this investigation suggest the following conclusions : 1. Authors induced anterior disc displacement surgically in rabbits with new method to examine histologic changes of posterior attachment. Tissue reactions of this model seem to be similar to those observed in human disc displacement. We think this animal model for anterior disc displacement may be used to explore and evaluate objectively the efects of many treatment modalities in disc displacements. 2. The animal disease model showed inflammation at early stage(one and ten days). At this stage there were mild-to-severe mononuclear inflammatory cell infiltration, numerous newly formed vessels, vessel dilatation and engormement and many fibroblasts. 3. At middle stage(three weeks), fibrosis occurred, where fibroblasts decreased in number, but their cytoplasm was profuse indicating high activity. Collagen fibers increased in number and the tissue looked more dense. 4. At late stage(five weeks and eight weeks) showed degenerative changes including perforation of posterior attachment, disintegration of collagen fiber bundles, degeneration of fibroblasts, metastatic ossification, and dystrophic calcification.

This paper presents a Reliability-Based Topology Optimization (RBTO) using the Evolutionary Structural Optimization (ESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. The Deterministic Topology Optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, the RBTO can consider the uncertainty variables because it has the probabilistic constraints, In order to determine whether the probabilistic constraint is satisfied or not, simulation techniques and approximation methods are developed, In this paper, the reliability index approach (RIA) is adopted to evaluate the probabilistic constraint, In order to apply the ESO method to the RBTO, a sensitivity number is defined as the change in the reliability index due to the removal of ith element. Numerical examples are presented to compare the DTO with the RBTO.

본 연구의 목적은 비파괴 평가방법인 공명초음파분광법(RUS)을 사용하여 세라믹제 페롤과 볼렌즈의 결함과 형상오차를 평가하는 것이다. RUS시스템은 스펙트럼에너라이저,파워 엠플리파이어,압전진동자센서와 지지프레임으로 구성되어진다. RUS 시스템에 의한 페롤과 볼렌즈의 비파괴평가를 위해 본 연구에서는 각 시험편에 대한 공진주파수를 측정하였으며,측정된 공진 주파수의 비교분석에 의해 결함의 유 · 무를 판별하였다. 그 결과 페롤의 경우,크랙을 갖는 페롤의 공진주파수 대역이 양품페롤의 공진 주파수 대역보다 고주파대역으로 이동함을 알 수 있었으며,볼렌즈의 경우,시험편 질량이 감소함에 따라 공진주파수 대역이 고주파 대역으로 이동함을 알 수 있었다. 또한 볼렌즈의 공진주파수가 측정되는 대역을 예측할 수 있는 파라메타인 β를 설정하여 그 결과를 고찰하였다. The objective of this paper is to evaluate the defect and shape error of a ceramic ferrule and ball lens by Resonant Ultrasound Spectroscopy(RUS) method. RUS system is consisted of spectrum analyzer, power amplifier, PZT sensor, and support frame. For nondestructive evaluate by using RUS system, first of all, we measured the natural frequency of each specimen, and we decided on the shape and size of flaw by measured natural ferquencies. And then, in the case of ferrule, natural frequency bandwidth of ferrule with crack was higher than acceptable ferrule. As mass of ball lens decreased, natural frequency bandwidth was shifting to high-frequency range. Thus, we discussed on the relationship between β and mass of ball lens, which β is parameter that we can predict measurable natural frequency bandwidth of ball lens.

예전 인구에 근거하여 연구된 논문들은 편두통이 뇌졸중의 위험성을 높일 수 있다는 보고를 하였으며, 전조증상을 동반한 편두통은 중추신경계와 연관된 병인론적 과정을 통하여 뇌졸중과의 관련성이 있다는 보고가 있다. 그러나, 편두통성 뇌졸중의 병태생리는 아직 정확히 밝혀지지 않았다. 편두통의 발생 원인에서 혈관성 이론은 편두통을 혈관수축으로 발생하는 전조증상과 함께 대뇌 조절 장애로 발생한다는 이론으로 뇌허혈증상은 일으킬 수 있다. 전조증상을 동반한 편두통성 뇌경색은 허혈성 뇌졸중의 드문 원인이며, 또한 편두통과 허혈성 뇌졸중사이의 관련성은 아직 논란으로 남아 있다. 우리는 혈관경련 수축으로 나타날 수 있는 전조성 편두통과 관련된 뇌경색에서의 가역적 후뇌 동맥 폐색 1례를 보고한다. Several previous population-based studies reported an increase risk of stroke in association with migraine. Migraine with aura increased stroke risk with pathogenetic process in the central nervous system. However, the pathologic mechanism of migrainous infarction remains elusive. The vasogenic theory ascribes migraine to cerebral dysregulation with aura resulting from vasoconstriction. Migrainous infarction with aura is a rare cause of cerebral ischemic stroke. Also, the relationship between migraine and ischemic stroke remains controversial. We report a case of cerebral infarction associated with migraine with aura that shows reversible arterial narrowing which might be caused by vasospasm.
