세포막하 선상구조 - 중배엽 기원세포의 미세구조적 표지로서의 의의 -
권태정,Kwon, Tae-Jung 한국현미경학회 1989 Applied microscopy Vol.19 No.1
Subplamalemmal linear densities (SLD) consist of a thin layer of electron dense material immediately subjacent to the inner leaflet of the palsma membrane. Short segments of extracellualr basal lamina-like material or collagen fibers usually overlie them. SLD has been considered to be a possible morphologic maker of cells of mesodermal origin. The present study confirms the fact that SLD may be of value in the diagnosis of mesodermal or mesenchymal tumor.
전자현미경 검사에 의해 확진된 균상식 육종(Mycosis fungoides) 1예
권태정,김정숙,이유복,Kwon, T.J.,Kim, C.S.,Lee, Y. B. 한국현미경학회 1982 Applied microscopy Vol.12 No.1
Mycosis fungoides is an uncommon, chronic fatal disease of lymphoreticular system associated with primary ski3 involvement for many years and terminating as a malignant lymphoma with involvement of lymph nodes and viscerae. On occasion it simulates numerous other nonspecific benign skin lesions, thus it may be impossible to decide whether the infiltrate represents early mycosis fungoides or nonspecific on the histopathologic ground alone. A case of mycosis fungoides was confirmed by electron microscopy and reported here. The patient was 69-years-old male who had suffered from erythematous scaly eruption on the whole body since 10 years. Skin biopsies of 4 times showed focal ulceration with chronic nonspecific inflammation and polymorphic cell infiltration in lower dermis, thus possibility of mycosis fungoides could not be completely ruled out. Electron microscopically several atypical lymphoid cells, which had a large cerebriform nucleus with peripheral condensation of dense chromatin and scant cytoplasm, were noted in the upper dermis. Intraepidermal infiltration of these atypical cells was also seen. It was thought that the electron microscopic study may be very helpful to differentiate equivocal mycosis fungoides from the nonspecific dermatosis.
기후변화시대 자연재해를 고려한 지속가능개발 개념의 재정립: 미국 방재동향 및 사례 분석을 중심으로

본 연구는 기후변화로 인하여 심각해져가고 있는 자연재해에 보다 효율적인 대응방안을 마련하기 위한 이론적 토대를 확립하고자 도시계획분야의 지속가능성 개념을 재정립하였다. 과거 지속가능성 개념에 대한 고찰과 최근 미국 방재학계의 동향을 분석하여 마련한 새로운 지속가능개발은 기존 환경분야 주요 목표인 환경보호와 더불어 이상기후로부터 도시 사회 안전성 확보가 포함되어야 함을 인식하였다. 그리고 도시 사회 안전성 확보는 저탄소녹색도시 관련요소와의 연계 속에서 이뤄져야 함을 강조하였다. 또한 환경, 경제, 사회분야의 목표를 동시에 추구함으로써 야기되는 갈등을 인식하고 대형화된 자연재해에 효과적으로 대응하기 위하여 기존 공학 시설중심의 구조적 방재대책과 더불어 비구조적 대책의 적극적 도입 필요성을 제시하였다. 본 연구에서 제시한 이론적 틀을 바탕으로 도시계획분야의 향후 연구는 갈등 조정 중재를 위한 새로운 제도적 틀 마련과 함께 APFM(the Associated Programme on Flood Management)에서 제시한 '노출(Exposure)'과 '취약성(Vulnerability)' 요인을 바탕으로 환경보호와 안전성 확보는 물론 관련 갈등해소에 기여할 수 있는 세부 요소 목표설정, 구체적 관련 기술개발 등에 노력해야 할 것으로 판단된다. The main purpose of this study is to reframe sustainability or sustainable development concept in the field of planning in consideration of climate change and natural hazards. The new concept is expected to provide a theoretical foundation for upcoming hazard mitigation measures addressing climate change. The first and main argument of the new concept is that environmental protection should be inclusive enough to address urban (or community) security from current natural hazards. The second is that the balance between structural and nonstructural mitigation measures is critical to cope more effectively with extreme natural hazards in the era of climate change and also with conflicts driven by three goals of sustainability--environmental protection, economic development, and social justice. The following studies, based on this new concept of sustainablity, are expected (1) to address new participation methods for the conflict resolution, (2) to explore detailed and substantive planning strategies and creative technical and institutional solutions for environmental protection, natural hazard mitigation, and conflict resolution. Two of APFM(the Associated Programme on Flood Management)'s three natural hazard risk criteria, Exposure and Vulnerability, may guide the exploration.

Gastric xanthoma which is not a true neoplasm and clinically insignificant consists of the small yellowish lesion of the gastric mucosa, frequently of multiple occurrence. Histologically the lesion shows chronic superficial gastritis with intestinal metaplasia and occasional collections of foam cells within the lamina propria. Electron microscopically. the xanthoma, cells are composed of. lipid-laden histiocytes with. many autophagocytic Iysosomes surrounding the cytoplasmic lipid vacuoles. Many residual bodies are also noted. The pathogenesis of the gastric xanthoma is obscure, however it is thought that a previous focal lesion of the gastric mucosa may have been a factor. One case of gastric xanthoma is reported here and a brief review of literature is also made.
폐조직내 Pneumocystis carinii의 전자현미경적 관찰
권태정,서영훈,김정숙,Kwon, T.J.,Seo, Y.H.,Kim, C.S. 한국현미경학회 1982 Applied microscopy Vol.12 No.1
P. carinii is a protozoan which induces an often fatal pneumonitis in a variety of compromised patients. The ultrastructure of P. carinii was studied in a male infant with pneumocystitis pneumonia associated with hypogammaglobulinemia. Four principal structural varieties-small trophozoites, large trophozoites, mature cyst and empty cyst were identified. The ultrastructure of these organisms was similar to the cases previously reported. Relevance of the morphologic findings to the functional aspect were discussed.
부산시티버스 태종대노선 경관유형 및 차량주행속도를 고려한 경관개선방안

The main purpose of this study is to lay a foundation for streetscape improvement along the Taejungdae line of Busan City Tour Bus. The Taejongdae Line is divided into thirty segments in consideration of the locations of tour bus stops and major intersections. Average travelling steed of the tour bus is measured for each segment. Nine types of streetscape and three driving speed categories are employed to form the foundation matrix. Streetscape improvement strategies are, then, proposed for each cell of the matrix. The matrix and the strategies are developed based on human visual perception and streetscape categories in the literature review, being expected to act as the catalyst for improving streetscape along the Taejongdae line and also the impression of the city of Busan. Further research is, however, needed to address pedestrian or passenger visual perception rather than driver.
