실험가토의 악관절원판 변위시 후방부착조직의 변화 : A NEW MODEL OF INTERNAL DERANGEMENT IN RABBITS

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 Evolutionary Structural Optimization (ESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic Topology Optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, RBTO involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance measure approach (PMA). Limit state function is approximated using Monte Carlo Simulation and Central Composite Design for reliability analysis. ESO, one of the topology optimization techniques, is adopted for topology optimization. Numerical examples are presented to compare the DTO with RBTO.

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.

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.

대용량 저장장치의 출현, 컴퓨터 성능 및 초고속 망의 급속한 성장, 디지털 필름스캐너의 성능 향상 및 비용 감소 덕분에 디지털 형태로 영상을 다루기 위한 요구가 점차 증대되는 추세이다. 디지털 영상은 항상 고품질을 유지해야 하므로 화소 당 비트를 높게 할당하는데 이때 소요되는 방대한 비트 수를 효과적으로 감소시켜 저장용량 및 대역폭을 줄이기 위해서는 효율적인 영상 압축이 요구된다. 본 눈문은 디지털 영상의 압축을 위한 새로운 이진적응 방식을 제안한다. 먼저 변환된 예측오류를 얻기 위해 적응예측을 하고, 모델 템플리트로부터 적당한 예측오류 값 영역을 하나의 context영역이 되도록 하는 방식으로 부호화에 적절한 수의 context 영역을 결정한다. 그리고 부호화 효율을 개선하기 위해 개별적인 context 영역에서 부호화 될 예측오류가 나타날 확률을 근접하게 추정한 후, 고 빈도 예측 심볼 집합을 이진적응에 적용하여 부호화의 효율을 개선한다.
