It is diffidult to distinguish benign from malignant, ulmonary nodule by conventional roentgenologic examination. But CT makes it easier to evaluate adjacent parenchymal invasion, pleural or mediastinal extension, or early metastasis to intra- or extrathoracic lymph node as well s distant organs, although only a solitary peripheral pulmonary nodule is seen on plain radiograph. Authors reviewed CT of 22 cases of histopathologically confirmed primary lung cancer seen as a solitary peripheral pulmonary mass from May 1980 to September 1984 at Dongsan Medical Center, Keimyung University. The results are as follows: 1. The incedence was most common in the 6th decade(36%). Male to female ratio was 10:1 and 2 females all had bronchioloalveolar cell carcinoma. 2. The distributions of histologic cell type were as follows: squamous cell carcinoma 40%, adenocarcinoma, small cell carcinoma, bronchioloalveolar cell carcinoma and unclassified carcinoma 14% in each cases, and adenoid cystic c rcinoma 4%. 3. The computed tomographic findings were as follows: a) Superior and posterior basal segments of both lower lobes were most frequently involved(68%). b) The mean diameter of the mass was 48mm, and most common in the range of 30-49mm in the greatest dimension(46%). c) The mean CT attenuation value was 57 H.U., and most common in the group of 41-70 H.U.(64%). d) Lymph node metastasis was found in 13(59%) of 22 cases, and the involved nodes were as follows: hilar nodes 10 cases, paratracheal nodes 8 cases, subcarinal nodes 7 cases and extrathoracic nodes 3 cases. In 2 of 3 cases with small cell carcinoma, diffuse multiple lymph nodes were involved. e) Distant metastasis was seen relatively early in 3 cases: cerebral metastasis in 1 case of squamous cell carcinoma, right adrenal metastasis without intrathoracic lymph node metastasis or invasion of adjacent structures in 1 case of bronchioloalveolar cell carcinoma, and liver and bone metastases in 1 case of unclassified carci oma. f) Adjacent pleural or mediastinal invasion was found in 7 cases(32%): pleural invasion alsong chest wall in 4 cases, and invasion of adjacent mediastinal pleura in 3 caes of 2 squmous cell carcinoma and 1 unclassified carcinoma. g) Calcifications within the mass were found in 5 caes(23%), and most common in squamous cell carcinoma(3 caes). In all cases, a few granular calcifications were seen along the peripheral margin of the mass. h) Tumor necrosis was seen in 4 cases(18%), and 3 cases were squamous cell carcinoma, and one of them showed irregular central cavitation. i) The margins of tumor were irregularly lobulated with radiating spiculations in all except one of adenoid cystic carcinoma, which revealed oval shaped, smooth clear margin. j) In 9(41%) of 22 cases, some enlargement of pulmonary vessels with perivascular linear infiltrations were found in the adjacent lung parenchymes of the mass, which were thought to be retrograde perivascular lymphangitic spread along pulmon ry vessels.

While the concept of applied art can be as a type of art works expressing the thoughts and feelings of the creator from the viewpoint of copyright law, it can be regarded as a practical design that expresses a form of useful article through industrial processes from the view point of design protection law. Such conceptual ambivalence of applied art causes various legal problems because it causes overlap of protection scope between copyright law and design protection law. Korea is taking attitude to alleviate the protection conflict of applied arts by actively accepting the interpretation theory of the copyright law which called "separability theory” in the United States through the revision of the copyright law in 2000. However, there are many differences from the United States in terms of the structure and system of legal regulations as well as general legal principals in the copyright law. So Korea is still in the imitation stage of the theory despite the need for a careful review process. As such, just relying on foreign interpretation which has not ended the controversy over the establishment of concrete criteria is hard to expect as a stable solution to the conflict problem between two laws. This study will play a role to search for improvement measures review the problems caused by protection scope of the two laws By analyzing the protection system based on the applied art revision of copyright law and the concept of design on design protection law of legal protection of applied art. In addition, this study will suggest redefining legal concept of applied art, way for reestablishment of intellectual property eligibility criteria and adjustment of protection scope and period for being duplicated protection problem of applied arts.

The localized intraabdominal bile collection or biloma has recently been diagnosed in increased frequency due to the wide spread use of US, CT, DISIDA scintigram, and radiologically guided percutaneous needle aspiration with or without subsequent catheter drainage. The underlying cause of biloma is trauma or iatrogenic injury which includes abdominal surgery, percutaneous drainage or PTC. We experienced 20 patients with 22 biloma diagnostically confirmed by DISIDA scan, image-guided needle aspiration, percutaneous catheter drainage and/or operation. Of the 22 biloma, 7 were intrahepatic and 15 were extrahepatic, Of the 15 extrahepatic biloma, 7 were in partially hepatectomized bed, 3 were subhepatic, 3 were right subphrenic and 1 was subcapsular. We were able to determine the infectivity in 16 biloma and of these 12 biloma were found to be infected. Percutaneous drainage was performed on 20 biloma in 18 patients : by a needle aspiration with irrigation on 2 patient and by perc taneous catheter drainage on 18bilomas. Overall success rate of the drainage was 90%. Cause of the two failures were CHD stone with choledochoduodenal fistula and recurrent hemobilia with acute cholecystitis. We describe the processes in reaching the diagnosis of biloma, propensity of biloma to purulent intrahepatic or perihepatic abscess formation, and the necessity of percutaneous radiologic catheter drainage as an optimal management.

CT is useful for the elderly patient in whom the diagnosis of periappendiceal abscess has not been suspected clinically due to an atypical clinical presentation. CT findings and its clinical applicability of periappendiceal abscesses were reviewed retros-pectively in 11 patients older than 40 years. The correct diagnosis was possible clinically in 4 patients(36%) The CT findings were mainly cystic (45%) of mixed (36%) masses which were located inferomedially to cecum(55%) or medially to right-sided colon (27%) The common associ-ated findings were adjacent peritoneal and intestinal thickenings mesenteric and/or omental ated findings were adjacent peritoneal and intestinal thickenings. mesenteric and/or omental infiltrations in most of the cases and retroperitoneal extensin of the inflammatory process(55%) . However there we five false-positive diagnoses in patients with a fluid-filled cecum a noncomplicated acue appendicitis and three chronic inflammatory diseases of the pericecal area. CT has the potential advantage of directly imaging the periappendiceal inflammation with a full assessment of the nature localization and extension of the abscesses and may guide percutaneous drainage of abscesses as an alternative to surgical drainage.

신세포암의 조직기원을 형태학적으로 규명하고자 외과적 수술로 적출된 5례의 신세포암조직에 대해 전자현미경 및 광학현미경적 관찰을 실시하였다. 광학현미경적으로는 clear cell 및 granular cell의 두 종류의 세포 형태가 나타났으며 이들은 분포비율은 다양하나 5례 모두에서 혼합되어 나타났다. 배열상은 충실형, 관형 및 소주형이 서로 섞여 나타났으며 심한 조직괴사를 동반하였다. 전자현미경적 소견에서 신세포암과 신근위뇨세관 상피세포와의 공통점이 발견되었으며 이는 주로 원형질막에서 관찰되었다. 이를 요약하면 첫째, microvilli 및 brush border 유사한 구조 형성, 둘째, microvilli 주변의 원형질막의 함몰 및 이와 유관한 것으로 보여지는 세포질내 coated vesicle 형성, 셋째, membrane coating, 넷째, intercellular junction을 들 수 있으며 관상 mitochondria 및 지방적, glycogen particle의 존재는 신세포암에 특징적으로 나타나는 소견이기는 하나 그 세포의 기원과는 관련성은 미약한 것으로 사료된다. 이상의 관찰로 신세포암은 clear cell과 granular cell이 같은 세포인 신근위곡뇨세관 상피세포에서 발생하였으며 그 형태학적 근거는 원형질막 구조의 특징적인 양상에서 볼 수 있었다. 이상 기저막의 형성 및 세포질내 filament 구조물에 대해서는 앞으로 더 많은 연구가 필요한 것으로 사료된다. The author studied five cases of surgically extracted renal cell carcinoma to investigate morphologic histogenesis. Obtained specimens are exmained under the light and electron microscopes. The results obtained were summarized as follow: Light microscopically, two types of tumor cells-clear cells and glandular cells-are present in mixed pattern of different proportions. They are arranged in mixed pattern of solid, tubular and trabecular type. Marked necrosis is combined. Electron microscopilly, related morphologic characteristics between the cells of renal cell carcinoma and normal proximal tubular cells are observed, especially in the plasma membrane. These are summarized as follow: 1) microvilli and brush-border like structure, 2) membrane invaginations associated with coated vesicle formation around microvilli, 3) membrane coating, 4) intercellular junctions. Other intracytoplasmic organelles such as tubular mitochondria, lipid droplets and glycogen particles are revealed as nonspecific findings of renal cell carcinoma. In conclusion, both clear and granular cells have common origin of proximal convoluted tubular cells. The specialized morphologic evidences are observed in the plasma membrane. More investigations are required about the abnormal basement memarane and intracytoplasmic filamentous structure.

김홍,강영구,유호석 한국산업안전학회 1997 한국안전학회지 Vol.12 No.3

본질적인 난연 및 내열성의 PQXS, PIQS, PQS 3종류의 폴리머를 2, 3-dichloroquinoxaline, 1, 3-dichloroisoquinoline, 4, 7-dichloroquinoline을 각각 출발 물질로 하여 합성하였다. 이들을 FT-IR, UV/Vis 분광분석, DTA, 원소분석 등에 따라 특성분석을 행하였다. 이들 폴리머소재는 내열 및 난연특성 시험에서 녹는점 기준 350℃ 이상의 높은 내열성과 LOI값 기준으로 41∼42의 높은 수치의 난연특성을 나타내었으며 또한 수직연소시험에서 UL 94 V-O 등급의 높은 난연특성을 나타내었다. The intrinsic flame retardant and heat resistant polymers such as PQXS[poly(quinoxaline)sulfide], PIQS[poly(isoquinoline)sulfide] and PQS[poly(quinoline)sulfide] were synthesized from 2, 3-dichloroquinoxaline, 1, 3-dichloroisoquinoline and 4, 7-dichloroquinoline. They were characterized by FT-IR, UV/Vis spectroscopy, DTA and elemental analysis. The melting point above 350℃ of the polymers show higher than that of the heat resistant PPS polymer(mp. 295℃). In the LOI test, the polymers exhibit an intrinsically high flame retardant property having the LOI values in the range of 41∼42. The vertical burning test for the polymers also show an UL 94 V-O performance.
