This paper deals with fast competitive learning using classified learning rates. The basic idea of the proposed method is to assign a classified learning rate to each weight vector. The weight vector associated with an output node is updated using its own learning rate. Each learning rate is changed only when its corresponding output node wins the competition, and the learning rates of the losing nodes are not changed. The experimental results obtained with image vector quantization show that the proposed method learns more rapidly and yields better quality that conventional competitive learning. 본 논문은 분류된 학습률을 이용한 고속 경쟁 학습에 대한 연구이다. 이연구의 기본 개념은 각 출력 노우드의 연결강도 벡터에 분류된 학습률을 할당하는 것이다. 출력 노우드의 각 연결강도 벡터는 자기 자신의 학습률에 의하여 갱신된다. 각 학습률은 관련되는 출력 노우드가 경쟁에서 승리할 때에만 변화되며, 승리하지 못한 노우드들의 학습률은 변화되지 않는다. 영상 벡터 양자화에 대하여 실험한 결과는 제안한 방법이 기존 경쟁 학습 방법에 비하여 더 빠르게 학습되고 더 좋은 화질을 갖게 됨을 보였다.

Epidermodysplasia verruciformis(EV) is a rare, sometimes familial disorder characterized by chronic infection with EV-specific HPV types. It manifests itself as numerous flat warts, red and brownish macules, and pityrias:s versicolor-like lesions. Immunodeficient staies such as AIDS renal transplantation, Hodgkins dis ase, and systemic lupus erythematosus, have been associated with EV. We report a case of a 42-year old female with EV, with lesions on the chest, shoulders, and back, For about the past 2, years, she had been treated with prednisolone for systemic lupus erythematosus. Histopathological findings revealed loose basket-weave-like hyperkeratosis and there were clear large cells arranged in nests in the granular and spinous layers. Their nuclei were shrunken and pyknotic, and the clear cytoplasm was dotted with dispersed keratohyaline granules of different sizes anr shapes. Electron microscopic findings showed aggregates of many viral particles in the nuclei of displastic epidermal keratinocytes. Pan papilloma virus monoclonal Antibody positive nuclei were;hown by immunoperoxidase staining. She has been treated with CO, laser and Tretinoin(0.1% ) oin ment. The patient is being monitored for any signs of recurrence for a period of 5months (Korean J Dermatol 1997;35(6): 1203-1207)

Hepatic encephalopathy, one of the major complications of cirrhosis, is a neuropsychiatric syndrome caused by accumulation of toxins in the central nervous system following dysfunction in liver detoxification. Various manifestations makes it difficulty to diagnose and categorize hepatic encephalopathy. For the consistency in diagnosis and staging of hepatic encephalopathy, standardized nomenclature regarding forms of hepatic encephalopathy was proposed recently. Due to the poor understanding of pathophysiology, effective prevention or treatment options are limited. Based on the theory that intestinal-derived ammonia plays major role in the development of hepatic encephalopathy, therapeutic approaches are directed at reducing intestinal bacterial production of ammonia and facilitating its elimination. Non-absorbable disaccharides, antibiotics such as rifaximin and L-ornithine-L-aspartate are main therapies for hepatic encephalopathy. Alternative therapies such as benzodiazepine receptor antagonists, branched-chain amino acids, sodium benzoate and acarbose have limited data supporting their use. Precipitating factors must be looked into carefully and corrected immediately because most patients are usually present with precipitating factors. Hepatic encephalopathy without precipitating factors shows poor prognosis and could be candidate of liver transplantation. (Korean J Med 75:27-36, 2008)
