The transient left ventricular apical ballooning syndrome, also known as takotsubo cardiomyopathy is a recently described novel cardiac syndrome. This syndrome is characterized by transient asynergy of the ventricular apex or mid-ventricle in the absence of obstructive epicardial coronay artery disease. This report concerns two types of morphologic difference about left ventricular apex and mid-ventricle. In this case, we report two types of stress-induced cardiomyopathy with review of literatures.

Purpose : We evaluated the usefulness of dynamic CT during portal phase with faster injection rate of contrast material in detecting hepatic metastases from gastric cancers. Subjects and Methods : We retrospectively analyzed two-phase dynamic CT findings (portal phase and equilibrium phase) in 17 patients with pathologically proven gastric cancers and hepatic metastases. In 13 patients, a total of 150ml of nonionic contrast material was administered with a power injector at a flow rate of 5ml/sec for 30 sec, and two-phase images were obtained at 45-70 sec (portal phase) and 2-4 min (equilibrium phase) after the start of bolus injection. In four patients, two-phase dynamic CT with spiral technique was performed with the same method. Results : In cases of metastases less than 1 cm in diameter, 65 lesions were detected in the portal phase that showed clearly defined hypodense lesions in highly enhanced hepatic parenchyma. Whereas, only nine (14%) lesions were detected in the equilibrium phase and the remaining 56(86%) lesions showed isoattenuation. In cases of metastases more than 1 cm in diameter, 37 lesions were detected in the portal phase that showed clearly defined hypoattenuations. whereas, the images of equilibrium phase showed isoattenuation in five (14%), mixed attenuation in three (8%), and hypoattenuation in 29 (78%). The lesions detected in the equilibrium phase showed poorly defined hypodense lesions and tended to decrease in size due to peripheral enhancement of lesions. Conclusion : Dynamic CT during portal phase with faster injection rate of IV contrast material is an useful technique in detecting hepatic metastases from gastric cancers, particularly small lesions less than 1 cm in diameter.

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 years of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth. We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.

A study on the recognition on the mushrooms by elementary school pupils, middle school students and school dietitians were-carried out. The ways of cooking mushrooms by school dietitians were also investigated. Most students and dietitians highly recognized mushrooms as good food. The most favorite mushroom was Flammulina velutipes, the cooking of mushrooms with meat and the hot mushroom soup with meat(Jungol) being the most preferred cooking methods. School ditetitians like to use mushrooms in school lunch and generally use medium or high quality mushrooms. Students, however, do not tend to prefer mushrooms compared to other vegetables. Mushroom dishes that can promote the consumption by students are mushroom bulgogi, mushroom pizza, sweet and sour mushroom in the order.

영역기반 피부영역검출을 위한 최소차원의 특징벡터공간 생성에 관한 연구

최종무,이준호 成均館大學校 科學技術硏究所 2001 論文集 Vol.52 No.1

본 논문에서는 효율적인 영역기반 피부 영역검출에의 적용을 위해 검출성능의 저하가 없이 최소차원의 특징벡터공간을 생성하는 방법을 제안하고 실험하였다. 제안한 방법은 입력 영상을 조각영상으로 분할하고, 각 조각영상의 Hue와 Saturation 값을 하나의 패턴으로 변환하여 고차원의 분류공간으로부터 최적으로 분류가 가능한 하위공간으로 사상하여 분류를 수행한다. 이러한 과정은 조각영상 내 화소들의 공간적 상관관계를 고려함으로써 분류 성능을 높이게 된다. 오프라인 학습단계에서는 조각영상의 패턴들에 LDA(linear discriminant analysis)를 적용하여 특징벡터들로 선형변환하고, 특징벡터의 각 원소 중에서 분별력이 가장 큰 두 개의 원소(element)만으로 2차원 LDA 인덱싱 테이블을 생성한다. 온라인 검출단계에서는 미리 생성된 2차원 LDA 인덱싱 테이블 룩업을 통하여 성능의 저하 없이 계산량을 상당히 줄일 수 있게 된다. 제안된 방법을 조명 및 손의 자세를 변화시킨 다양한 영상에 적용하여 실험한 결과 양호한 검출 결과를 얻을 수 있었다. This research presents a novel method for region based skin color segmentation. It considers spatial correlation of pixel values in a local region using a feature vector space of minimal dimensionality. We have employed a 2D feature vector space that is implemented as an indexing able. The input image is divided into patch images and each patch mage is converted to a pattern vector of which elements are hue and saturation values of the pixels in the patch. These pattern vectors are classified into skin color or non-skin color regions using 2D indexing table. We show that employing this 2D indexing table gives accurate classification of high dimensional pattern vectors. At off-line learning stage, we apply LDA(linear Discriminant Analysis) to the pattern vectors from the patch images and construct a 2D indexing table of which two axes are the most discriminant elements of feature vectors, At on-line detection stage, we can achieve fast skin color segmentation by 2D indexing table lookup. We have applied our method to various images under illumination changes and different poses. The experimental results show that the performance of our method is quite robust to illumination changes and different poses.
