The purpose of this research is to investigate appropriate usage of pansori's method of breathing, sound making, and resonance in order to develop actor's aesthetic voice. Today's theatre no longer see inter-cultural approach as new or experimental, but see it as a part of global current. Actors are required to integrate some global-ness into their acting. It's not enough, however, for actors to equip some cosmopolitan sensibility. More important thing is that they should be able to integrate one's own culture and aesthetic into their performance. Only after acquiring one's own cultural identity, it is possible to step into inter-cultural work. It is fundamental, therefore, for actors to assimilate traditional movement and aesthetic voice. It's been known that traditional Korean voice traits are well preserved in Pansori. In this paper, based upon well-known theories and practices of western voice training, pansori's principles and practices are utilized to bring a new aesthetic voice.

사람의 발성 기관은 공기를 짜내어 주는 역할을 하는 호흡기관(breathing apparatus)과 소리의 원음을 만들어 내는 성대(vocal folds) 그리고 성대로부터 만들어진 원음을 공명 (resonance) 시키고 여과(filtering) 시킴으로써 특징적인 소리의 모양을 갖추는 역할을 하는 성도(vocal tract)로 크게 나누어 볼 수 있다.

음성은 단순히 성대에서 만들어지는 것이 아니다. 호흡을 시작으로 성대의 접촉과 점막 진동에 의해 만들어진 소리가 공명강을 거쳐 입술, 혀의 움직임을 거쳐 최종적으로 의미를 전달하는 소리로 완성된다. 기능성 음성 질환은 이러한 과정 중에서 발성 방법과 같은 기능적 문제에 의하여 발생하게 된다. 따라서 기능성 음성 질환이 있을 때 이러한 과정의 움직임에 대한 조사가 필요하다. (중략)

Primary neuroendocrine carcinomas of the breast are a rare, distinct category of breast carcinomas that require immunohistochemical staining for diagnosis. Currently, there is not enough evidence on the clinical pattern, prognosis, and proper management of the disease. Only few case series have described the imaging findings of neuroendocrine carcinomas of the breast. We herein present a case of a primary neuroendocrine carcinoma of the breast (small cell) presenting as a locally aggressive tumor with metastatic disease, and describe the radiologic findings.

Primary angiitis of the central nervous system (PACNS) is a rare vasculitis in the central nervous system. Herein, we report a case of diagnosis and treatment of necrotic pattern PACNS, which was difficult to differentiate from a brain abscess. A 19-year-old male presented with blurred vision and a headache. Brain MRI revealed irregular rim-enhancing necrotic masses with central diffusion-high signal intensity in the corpus callosum and peripheral diffusion-high signal intensity in the left parietotemporal periventricular area. Susceptibility-weighted imaging revealed multiple punctate hemorrhages in the lesions. The patient was diagnosed with unusual abscess or tumefactive PACNS. Therefore, we initially treated the patient with antibiotics to rule out brain abscess. However, the brain lesions did not improve on follow-up MRI after the antibiotic treatment. Surgical biopsy was performed, and the histopathological diagnosis was PACNS with a necrotic pattern. The necrotic lesions became smaller on follow-up MRI after high-dose corticosteroid treatment.

Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.

Primar99y cardiac tumors are rare and about 25% of primary cardiac tumors are malignant. A primary undifferentiated cardiac sarcoma, which very rare, is presented as follows: A 28-year old woman at the 32th week of pregnancy was admitted to the hospital because of dyspnea. A large intracardiac (left atrium) tumor was found with cardiac echocardiography and MRI. Emergency operation was performed under the diagnosis of left atrial myxoma. After Cesarean section, LA-tomy was done under the cardiopulmonary bypass. Tumor removal including endocardium of left atrium was done and final pathologic diagnosis was primary undifferentiated laft atrial sarcoma. After adjuvant radiotherapy, she has been followed up in out patient bases without problems up to now.

Primary malignant melanoma in breast parenchyma (PMB) is an extremely rare disease, and the most common presentation is a palpable breast lump. To the best of our knowledge, a case of PMB presenting as a breast abscess has not been reported in English literatures. We present a case of PMB that manifested as a recurrent breast abscess in a 71-year-old woman. On MRI, an enhancing solid mass with a cystic or necrotic portion was revealed with some high signal intensities on precontrast-enhanced T1-weighted images and a dark rim on T2-weighed images. The MRI features played a pivotal role in identifying the underlying malignant condition and making an accurate diagnosis of this rare case of PMB with unusual clinical presentation.

Primary cardiac lymphoma is an extranodal malignant lymphoma of any cell type involving only heart and pericardium without dissemination. Patients usually present symptoms of heart failure, arrhythmias, pericardial effusion and cardiac tamponade. Diagnosis of primary cardiac lymphoma can be performed by echocardiogram, CT and MRI and cytologic examination of pericardial effusion or transvenously biopsied cardiac tissue. Prognosis of primary cardiac lymphoma is poor. Because of poor prognosis, early diagnosis and complete surgical excision is essential and postoperative systemic chemotherapy or radiotherapy is useful. In this case extensive tumor infiltration on the right ventricle and atrioventricular groove preclude surgical excision. Tissue biopsy revealed primary cardiac lymphoma. After postoperative chemotherapy and radiotherapy, the size of intracardiac mass is decreased in follow up chest CT scan and echocardiogram and symptoms of patient are relieved. Therefore, we report a case of primary cardiac lymphoma with review of literatures.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.
