본 논문은 다구간 등분할법과 퍼지추론으로 단어인식을 행하는 패턴매칭법을 제안한다. 패턴매칭시 발생되는 시간변동은 발성순서에 따라 등간격으로 다구간 분할함으로써 해결하고, 주파수변동은 구간의 차수별로 정해진 퍼지관계로부터 패턴간의 퍼지추론이 행해짐으로써 흡수한다. 추론에 사용된 삼각형 맴버쉽 함수의 중심값과 변동폭은 패턴의 평균값과 분산값으로 대응되도록 작성한다. 20대 남성 2인이 발성한 데이터를 사용하여, 제안된 방법으로 DDD지역명 28개를 구간수와 변동폭을 달리하여 인식실험한 결과, 8구간과 4배의 변동폭을 가질 때 92%의 인식을 얻었다.

목소리를 많이 사용하는 사람들에서 발생되는 음성장애는 대부분 잘못된 발성방법으로 인한 후두의 과긴장으로 인해 야기되는 것으로, 흡기 및 호기를 자발적으로 조절할 수 있는 호흡방법과 성대 및 주변 근육의 긴장을 줄이도록 하는 훈련하는 음성치료가 주된 치료 방법으로 대두되고 있다. 지금까지 음성치료의 효과는 주로 청음인지적(perceptual) 측면에서 많이 논의되어 왔으며 객관적인 자료는 아직까지 별로 없는 상태이다. 더욱이 호흡 및 발성 방법에 따른 음성 분석은 미진한 상황이다. (중략)

재즈음악이나 재즈콘서트는 근래에 들어서 가장 접하기 쉬운 문화예술의 한 장르이다. 재즈 공연을 보기 위해 많은 관객들이 찾고 있으며 이러한 공연은 현재의 대표적인 공연 문화로 자리 매김하고 있다. 그에 반하여 음악연주 자체에 대한 평가나 관객의 반응에 대한 평론이 비전문가적인 부분이 많아서 좀 더 전문성을 갖춘 보컬연주의 이해와 중요성에 대한 교육이 필요하게 되었다. 본 논문은 재즈를 노래하는 사람이 표현하고자 하는 모든 부분을 자유롭고 말하듯이 편안하게 노래하는(지성으로 노래하기) 발성방법과 호흡에 대한 연구이다.

최근 컴퓨터와 인간간의 대화 수단으로 음성을 활용하는 기술인 음성정보기술이 발달함에 따라 대어휘 연속 음성 인식 및 무제한 어휘 음성 합성의 고도화를 위한 연구가 진행되고 있다. 음성 인식의 경우 HMM으로 대표되는 통계적 수법의 발달에 따라 시스템의 학습을 위해 대량의 음성데이터가 필요하며, 음성 합성의 경우에도 최근 대형의 음성 데이터 베이스로부터 임의 길이의 음성 부분을 골라내어 접속함으로써 좋은 합성 품질을 얻고 있다. 본 논문에서는 이러한 음성 인식 및 합성을 위해 공동으로 사용하기 위한 음성 데이터베이스의 발성 목록을 설계하고 설계된 결과에 대하여 논의한다.

Whether respiratory muscle training is of benefit to the singing students is controversial. The purpose of the study is to investigate pulmonary function and the maximal inspiratory(MIP) and expiratory pressure(MET), and maximum phonation time in five female singing students before and after the specially programmed respiratory muscle training during 2 months. All singing students had average 4.8 years of formal classical voice training. Respiratory muscle training machine (Ultrabreath) was used to train respiratory muscle. Pulmonary function test data on simple pulmonary function, flow volume curve, static lung volumes are obtained from Vmax 6200. The MIP and MEP were measured using Spirovis, and the MPT were measured using hand-held stopwatch. Any pulmonary function test variables are not changed after respiratory muscle training. However, MIP and MEP were significantly increased between before and after respiratory muscle training. MPT increased significantly after training, compared to the pre-trained. MIP, MEP, and MPT after training in female singing students were 26%, 25% and 33% higher than those before training. The result indicated that the specially programmed respiratory muscle training is beneficial to improve respiratory muscle strength and vocal function without an increment in pulmonary function.

Autoimmune hepatitis (AIH), primary sclerosing cholangitis (PSC), and primary biliary cirrhosis (PBC) are chronic autoimmune liver diseases. Overlap syndrome is defined as a condition in which the clinical, biochemical, and histological features of these autoimmune diseases are overlapped. Thus, it is difficult to appreciate overlap syndrome as an actual diagnostic entity. Only a few cases of the overlap syndrome of AIH and PSC have been reported, especially in children. Moreover, PSC is known to be the most frequent liver disorder associated with inflammatory bowel diseases such as ulcerative colitis. We report one case of AIH-PSC overlap syndrome in a child who was diagnosed as having ulcerative colitis.

Primary cardiac tumors are rare disease and they present nonspecific symptom. They are divided in benign and malignant tumors and require surgical therapy and/or additional therapy. From March 1995 to March 2003, twenty one patients were diagnosed as having primary cardiac tumors. We analysed them retrospectively in terms of various perioperative factors and early and late results. 6 men and 15 women and their average age was 45.44$\pm$18.76. Pathology revealed eighteen benign (fourteen myxoma, two fibroelastoma, one hemangioma and one paraganglioma) disease and three malignant (one angiosarcoma, one mesothelioma and one myxofibrosarcoma) disease. There was one (myxoma) operative mortality and three late death (hemangioma, angiosarcoma and mesothelioma) during additional therapy and follow up. Surgical treatment of primary cardiac tumor is important and sometimes additional therapy is required but the prognosis of malignant cardiac tumor is still very poor.

A multiple primary malignant tumor is a disease mainly encountered in the of the older age groups. Attempts should be made to rule out a second primary malignant neoplasm in the elderly patients with unusual signs and symptoms. We encountered a case of a 67-year-old male with triple primary malignant tumors of the stomach, larynx, and lung. The patient had been treated with a subtotal gastrectomy for early gastric cancer in 1991 and a Laser laryngectomy for the laryngeal squamous cell carcinoma in 2003. In 2005, lung cancer was found with the biopsy revealing an adenosquamous carcinoma. Systemic chemotherapy was performed.

A 5-year-old male Cocker spaniel was presented with an abrupt seizure episode. The dog was moderately dehydrated, hypersalivation and loss of consciousness at the presentation. Tentative diagnosis was made through history taking, clinical signs, physical examination, neurologic examination, basic laboratory examinations, radiological examination and cytologic examination. In addition, serum alpha-fetoprotein (AFP) value was measured to diagnose in this case. The serum AFP concentration was marked elevated (1513.5 ng/ml). The patient was suspected as HCC and medical therapy was initiated to control hypoglycemic-associated seizure. However, the dog was euthanized because of the owner's request. It was diagnosed as hepatocellular carcinoma (HCC) based on the histopathologic examination. This case indicates that AFP measurement might be valuable to diagnose HCC in dogs.

Chest wall metastases from malignant tumors are rare and the majority of them are from adjacent structures such as the breast, lung, pleura, and mediastinum. Paticularly, chest wall metastases from distant organs are an even rarer event. There are few reports of chest wall metastasis with obscure or absent primary tumor. A 51-year-old man was diagnosed with metastatic hepatocellular carcinoma after an operation for a palpable mass on his left upper chest wall, At that time, there was no evidence of primary hepatocellular carcinoma in the liver after various examinations. We report a case of chest wall metastasis from unknown primary hepatocellular carcinoma.
