  • The experiment on study of ambient nose generated by large-amplitude internal waves in Luzon Strait is analyzed. Simultaneous observations of internal waves and characteristics of ambient noise generated by them were carried out. Fast 50-m solitary internal wave propagated to the northwest direction with speed more than 3 m/s was observed. It was revealed an enhancing of ambient noise level (at frequency range 1-2 kHz) at a time of passing the face side of the solitary wave.

  • Solitary fibrous tumor is a spindle cell neoplasm that can arise in any place of the body. Intracranial solitary fibrous tumors are rare. To our knowledge, only 57 cases with intracranial lesion have been reported. In Korea three cases have been reported. Our case was a 23-year-old woman who presented with morning headache. MRI showed a large intra-axial mass involving falx with typically isointense and heterogeneous strong enhancement on T1 weighted image in the right parieto-occipital region. Histologically the tumor showed spindle shaped cells within matrix with thick collagen deposition, hypercellularity, focal necrosis, and pleomorphism. Immunohistochemical study demonstrated diffuse positivity for CD34, Vimentin, Reticulin. In case of the intracranial tumors involving the meninges, we also should consider the solitary fibrous tumor with immunohistochemical staining for accurate diagnosis.

  • 고립성 섬유성 종양은 주로 흉막에서 발생하는 드문 종양으로 중피하 중간엽에서 기원하며 드물게 흉막 외에서 발생하기도 한다. 많은 경우에서 증상이 없이 우연히 발견되나 다른 중요 장기를 침범하거나 종양의 크기가 커질 경우 증상이 나타나기도 한다. 일반적으로 진단은 영상의학적 검사와 세침흡인을 통한 생검으로 하며 면역조직화학검사를 시행하여 더 정확히 판별할 수 있다 대부분의 경우 양성의 경과를 보이며 병변의 완전한 제거 여부가 가장 중요한 예후 인자가 된다고 알려져 있다. 저자들은 우하엽에 발생한 폐실질 내에 생긴 고립성 섬유성 종양을 채기 절제술로 치험하여 이에 보고하는 바이다

  • The experience with operative treatment for peripheral situated solitary circumscribed lesions of the lung at the Department of Thorac. & Cardiovasc. Surg., Korea University Hospital during 8 years from March 1974, through April, 1982 was reviewed. Our criteria for Solitary pulmonary nodule were 1. Round or Ovoid shape 2. Surrounded by normal lung Parenchyme 3. Well circumscribed peripheral location 4. No other visible pulmonary diseases on chest X-ray except minimal atelectasis or pneumonitis 5. Largest diameter less than 8 cm Of the 55 patients reviewed, there were 69% of malignancy and 31% of benign pulmonary diseases. In malignancy 38 patients, there were 18 patients with squamous cell carcinoma, 8 patients with undifferentiated large cell carcinoma, 2 patients with undifferentiated small cell carcinoma, 10 patients with adenocarcinoma and patient with metastatic carcinoma. In benign pulmonary nodule 17 patients, here were 5 patients with tuberculoma, 5 patients with aspergilloma, 2 patients with A-V fistula, 1 patient with pulmonary blastoma, 1 patient with paragonimiasis, and 1 patient with lung abscess. Overall male to female occurrence ratio was 39:16, and most prevalent age incidence was 7th decades. Most frequent size distribution was 4-6 cm in diameter. All of benign diseases were cured by resection and 66% of malignancy performed operation and has 75% resectability.

  • Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

  • The 2019 novel coronavirus (2019-nCoV) outbreak in Wuhan, Hubei Province, China in 2019 led to large numbers of people being infected and developing atypical pneumonia (coronavirus disease 2019, COVID-19). Typical imaging manifestations of patients infected with 2019-nCoV has been reported, but we encountered an atypical radiological manifestation on baseline computed tomography (CT) images in three patients from Wuhan, China infected with the 2019-nCoV. Surprisingly, the only similar CT finding was a solitary sub-centimeter ground-glass nodule adjacent to bronchovascular bundles, which could be easily overlooked. In addition, the follow-up images in these patients showed how COVID-19 pneumonia evolved from these small nodules. The radiologic manifestation of the three cases will expand contemporary understanding of COVID-19.

  • Solitary plasmacytomas are rare and account for 5-10% of all plasma cell disorders. These tumors are categorized as solitary plasmacytomas of bone(osseous) or extramedullary plasmacytomas(non-osseous). About a half of solitary plasmacytomas of bone occur in the spine but rarely in the skull. We report a case of solitary plasmacytoma of the skull presented with a painless palpable left parietal calvarial mass in an otherwise asymptomatic 38- year-old man. Skull radiographs showed a large radiolucent lesion with well defined non-sclerotic margins. Computed tomograph scan demonstrated a markedly enhancing mass extending from the epidural to the subcutaneous space. The patient underwent surgery and tumor was completely excised. Pathological examination showed tumor to be a plasmacytoma synthesizing IgG. Postoperatively, the patient received radiotherapy. There was no evidence of systemic involvement on postoperative laboratory wokups. Our recommended treatment is a complete surgical excision combined with postoperative radiation therapy. The patient should be follwed carefully for more than 10 years because of either local recurrence or possible progression to multiple myeloma.

  • 흉막에 발생한 고릴성 섬유종은 비교적 회귀한 질환으로 알려져 있으며, 대부분 장측 흉막에서 발생하고 벽측 홍막에서 발생되는 경우는 매우 드물다. 저자들은 48세 여자환자에서 우흉곽내 벽측 흉막에서 발생한 거대 고립성 섬유종 1례를 수술 치험하였다. 환자는 10개월전 부터 발생한 호흡곤란이 주증상이었고, 술전 흉부전산화 단층될영상 우측 폐실질을 주변으로 밀어내는 이종의 종괴형태를 보였다. 수술 소견상 종괴는 피낭에 싸여 있었고, 벽측 흉막에서 기 시하였다. 절제된 종괴의 크기는 20cmX15cmX11cm였고, 무게는 2200gm에 이르렀다. 환자는 합병증없이 퇴원하였으며 술후 6개월 간 추적 관찰하였으나 재발의 소견없이 양호한 상태를 보이고 있다.

  • A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

  • This research is about shared living facilities for the solitary elderly in Gyeonggi province (so called "Carnation House"), which was opened after 2013. These facilities aim to help solving the social problems of the growing number of the solitary elderly. The research was conducted from April 2014 to October 2014 by using observation, measurement, photography, and interview methods. This research reviewed floor plan, area, accessibility, visual openness, and furniture and equipments. The results are as follows: First, considering the need for rest area and the protection of privacy, livingroom should at least be equipped with a variable wall or have a separate room. Secondly, for the kitchen plan, considering the fact that large number of people move simultaneously, kitchen entrance should be widened or LDK type is preferable. Thirdly, the bathroom entrance should be widened to at least 800mm and should have barrier free design. Fourthly, porch entrance should be planned to secure enough space and shoe cabinets for multiple users. Fifthly, to allow the users to enjoy outside view, the windows of living spaces should be placed no higher than 800mm from the floor level. Finally, for the location of the facility, people prefer the location be at the center of the village or near home. In addition, location with easy accessibility for the elderly is advisable. Therefore, establishing local guidelines for shared living facilities for the solitary elderly is advisable. When establishing local guidelines, local characters, culture and usage patterns should be considered.
