Spatio-temporal 방법을 이용한 우리말 모음 인식에 관한 연구
송도선,김선일,김석동,이행세 한국음향학회 1993 韓國音響學會誌 Vol.12 No.4
본 논문은 신경망을 이용한 우리말 모음에 대한 인식 연구이다. 음성을 나누거나. 음소별 인식이나, 시간 신축 방법을 사용하지 않고 모음을 인식하였다. 식나의 변화에 따른 음성의 변화를 정적인 음성으로 취급하였다. 10개로 균등히 나눈 프레임에 각 프레임마다 10차의 PARCOR계수를 추출하였다. 신경망의 구조를 간단히 하기 위해서 단모음과 복모음을 구분하여 학습시켰으며, 출력 노드의 수를 감소시키기 위해 이진 코드 형태로 구성하였다.

Alcoholic liver disease is a major cause of liver disease that results in significant morbidity and mortality in Korea. Abstinence is the most important strategy to prevent disease progression. Corticosteroids improve the one-month survival in patients with severe alcoholic hepatitis, but it was not effective on long-term survival. An N-acetylcysteine treatment combined with corticosteroids may provide a short-term survival benefit than corticosteroids alone. Pentoxifylline is unlikely to affect short-term survival. Hence, studies on new therapies, such as granulocyte colony-stimulating factor and fecal microbiota transplantation, are ongoing. This paper briefly reviews the current knowledge of the medical treatment of alcoholic liver disease.
Treatments Other than Sorafenib for Patients with Advanced Hepatocellular Carcinoma
송도선,배시현 대한간암학회 2016 대한간암학회지 Vol.16 No.1
Sorafenib is the standard treatment for advanced hepatocellular carcinoma according to the Barcelona Clinic Liver Cancer staging system. However, because of its unsatisfactory efficacy, adverse effects, and high cost, the use of sorafenib is limited, and other treatment modalities are required. Recent studies reported that treatment modalities other than sorafenib, such as hepatic arterial infusion chemotherapy and transarterial radioembolization, showed comparable or better response rates and survival rates than sorafenib. In this review, treatment modalities that could be used as alternatives to sorafenib will be discussed.

A modified Hybrid learning rule(MHLR) is proposed, which is derived from combining the Back Propagation algorithm that is known as an excellent classifier with modified Hebbian by changing the orginal Hebbian which is a good feature extractor. The network architecture of MHLR is multi-layered neural network. The weights of MHLR are calculated from sum of the weight of BP and the weight of modified Hebbian between input layer and higgen layer and from the weight of BP between gidden layer and output layer. To evaluate the performance, BP, MHLR and the proposed Hybrid learning rule (HLR) are simulated by Monte Carlo method. As the result, MHLR is the best in recognition rate and HLR is the second. In learning speed, HLR and MHLR are much the same, while BP is relatively slow.
한국의 Acute-on-chronic Liver failure (ACLF)에 관한 후향적 다기관 코호트 연구
송도선 대한간학회 2015 간학회 싱글토픽 심포지움 Vol.2015 No.1
The concept of acute-on-chronic liver failure (ACLF) has emerged to account for the rapidly deteriorating liver function in the patients with underlying chronic liver disease (CLD). Even though the definitions of ACLF were proposed by Asian Pacific Association for the Study of the Liver (APASL) and European Association for the Study of the Liver-Chronic Liver Failure Consortium (EASL-CLIF Consortium), the differences between the 2 definitions have resulted in confusion rather than clarification. Korean Multicenter cohort study of ACLF (Korean Acute-on Chronic Liver Failure study, KACLiF) were performed from 2013. This study aimed to investigate the prevalence and prognosis of ACLF patients according to two different definitions and bridge the difference between two definitions. The ACLF was frequent in the patients with acute decompensation of CLD, and the prognosis was poor. We suggest that CLD other than liver cirrhosis as underlying liver disease and previous acute decompensation should be included as ACLF definition, and extra-hepatic organ failure should be considered significantly. Chronic liver failure sequential organ failure assessment (CLIF-SOFA) score was useful scoring system to provide accurate information on prognosis in the patients who admitted for AD, especially in the patients with ACLF. Prospective cohort study planning to start soon is likely to help to understand and better define ACLF.

본 논문은 영재성의 중요한 요소 가운데 하나인 지력(知力)에 초점을 두어, 이에 대한 생득설과 경험설의 입장과 그에 대한 영향력에 대한 다양한 연구들을 종합·분석하고, 이와 관련된 몇 가지 논의를 함으로써 영재성을 이해하는 데에 목적을 두고 있다. 다양한 연구 내용들을 검토한 결과, 인간의 지력은 절반 정도는 타고난다는 것이 보편적인 입장이었다. 하지만 중요한 것은 그것이 평생 고정되는 것이 아니라 후천적 경험에 의해 변하고 발달한다는 점이다. 결국 지력이 중요한 요소인 영재성 자체는 잠재력으로 타고나는 것이지만, 그것은 여러 가지 환경 요인에 따라 그 발현의 여부나 정도가 결정된다는 것이다. 따라서 영재교육에 관한 오늘날의 주요 관심은 생득 요인과 후천 요인의 정도에 대한 논쟁보다는, 그 영재성을 후천적으로 어떻게 최대로 발현시킬 것인가에 있다. 영재성은 뛰어난 유전 요인과 특별한 환경 요인이 역동적으로 상호작용하여 쌍방향의 절묘한 증폭현상이 일어날 때 비로소 촉발되고 발달한다는 점에서, 그것을 도식적으로 설명하는 데에 깊은 난관이 있음을 이해할 수 있다. The purpose of this study is to investigate the two assertions of hereditarianism and environmentalism in the intellectual abilities, which is one of the most important factors of giftedness, and thus to discuss and understand giftedness. As the result of various investigations about the two opposing opinions, it is general view that about 50% of the intellectual abilities are endowed by genetic factors, but they are not fixed life long but changed and developed by posterior experiences. In other word, it is said that giftedness itself of which an important factor is intellectual abilities is determined by heredity, but the degree of revelation of the potential faculty is determined by environmental factors. Therefore, the recent major concerns in this field seem to be on how to make unfold most the children's giftedness rather than arguments about the degree of genetic and environmental factors. It can be said that giftedness is sprung up and accelerated only when an excellent genetic factor and a special environmental factor are transacted dynamically and amplified exquisitely.
