成台慶,李永根,宋鎭彦 中央醫學社 1974 中央醫學 Vol.27 No.6

Supratentorial hemangioblastomas are extremely rare since almost all of the hemangioblastomas of the central nervous system were occurred in the cerebellum. We have experienced a case of the right parieto-occipital hemangioblastoma which was removed successfully and confirmed histologically. A 64-year-old woman was admitted to St. Mary's Hospital, Catholic Medical College in October, 1973, because of headache, vomiting, left hemiparesis and mental confusion. She had had severe headache since 6 months prior to admission and associated with frequent nausea and vomiting. Mental confusion and progressive left hemiparesis were detected by family since 2 months prior to admission. On admission, neurological examination revealed drowsiness and disorientation. Ophthalmological examination disclosed visual impairment, papilledema and left inferior quadrantanopsia. There was left face supranuclear type weakness and left hemiparesis with positive pathological reflex. Right carotid angiogram showed a well demarcated homogenous round tumor stain at paramedian area of the right parieto-occipital Iobe. Brain scan with 99'Tc pertechnetate showed a round uptake at the right parieto-occipital region. Through the right temporo-parieto-occipital craniotomy we found a brownish red solid mass which was embedded into medial aspect of the occipital lobe adjacent to falx. The tumor was not attached to the meninges or falx. The tumor was successfully removed en bloc, and it was measured 5. 5cm X4. 5cm X2. 5cm in size. Postoperative course was uneventful and follow-up observation noted improvement of previous symptoms and signs except visual defect. Histological features of the tumor showed numerous delicate vascular channels primarily of capillary type with blood in the lumina of the large vessels. Histological diagnosis was hemangioblatoma.

Suprasellar Germinoma : Ectopic Pinealoma So Called Ectopic Pinealoma 1例 報告

成台慶,李永根,宋鎭彦,李秀南,李鍾武 中央醫學社 1975 中央醫學 Vol.28 No.1

Tumors histologically identical to the seminomas and dysgerminomas of the gonads occur intracranially and are commonly known as "atypical teratoma" or germinoma. The suprasellar germinomas or so called "ectopic pinealomas" were first separated from pineal germinomas as a distinct clinical entity by Kageyama and Belsky in 1961. We have experienced a case of suprasellar tumor which was confirmed as germinoma histologically after biopsy of the tumor. A 21-year-old man was admitted to St. Mary's Hospital in October 1974, because of headache, vomiting and progressive visual impairment for about 3 months. Clinical examination revealed bilateral visual impairment and papilledema without visual field defect. The urinary specific gravity was fluctuating with tendency of lower level. Plain skull showed an erosion of the dorsum sellae. Pneumocisternogram showed a filling defect between interpeduncular cistern and prechiasmatic cistern and Conray ventriculogram showed a filling defect of anterior-inferior portion of the 3rd ventricle with dilatation of the lateral ventricle but posterior portion of the 3rd ventricl- showed normal contour without blocking of c. s. f. pathway to the aqueduct of sylviu& Biopsy of the suprachiasma mass was performed through right frontal craniotomy, and microscopic examination of the specimen showed two cell types, one large and epitheloid, the other small round lymphocytic cells, with the characteristic microscopic patterns of germinoma. A transient mental confusion was manifested postoperatively but subsided later and discharged without complications. Patient is receiving irradiation therady.

한국의 제3세대 과학기술도시에 관한 연구

성태경,이상규 경기대학교 1999 論文集 Vol.43 No.1

Technopoleis development in Korea can be categorized into three distinctive generations. The first generation was in the 1970s and the 1980s when Taedok Science Town, the first technopolis, was being built. The second generation occurred in late 1980s and early 1990s when the objective of technopoleis development was to vitalize the local economy. The third generation of technopoleis development started mid 1990s when the local governments began to get actively involved in the establishment of technopoleis to boost their regional economies in the era of local autonomy. The central government has thus established six strict criteria to govern technopolis development. They are: (1) clarity of roles of all participating sectors, (2) clarity of objectives, (3) specialization, (4) openness, (5) creating synergistic connections among participants, and (6) healthy state of competition to exist. The current central government policy on new technopoleis development clearly dictates that the financial support for the technopolis development of the local government will be made only if the local or the provincial government surpasses criteria set by the central government. For the year of 1998, a total number of thirteen technopoleis, representing each province, have applied for central government financial support. Each technopolis passed the pre-screening process from the provincial government prior to the evaluation of the central government. To impartially evaluate submitted proposals for the technopolis development from local governments, the central government has devised the following judgment scheme. This scheme consists of five categories, twelve major items, and thirty-eight detailed items. The categories are (1) appropriateness of proposal, (2) initiating sector characteristics, (3) site conditions, (4) funding and investment options, and (5) success potential. The final six nominated technopoleis that received the financial support are Taegu-Kyungbuk, Kwangju-Chunnam, Songdo, Chungnam, Ansan, and Kyungsan. It is expected that the future development policy of technopoleis in Korea will not be dramatically changed from that of current policy and will fine-tune the current policy as socio-economic environment dictates.

차량 항법을 위한 지도 정합법 개발

성태경,표종선,Sung Tae-Kyung,Pyo Jong-Sun 대한전자공학회 2005 電子工學會論文誌-SC (System and control) Vol.42 No.4

본 논문에서는 다중 가설 기법을 이용한 차량 항법용 지도 정합법을 제안하였다. 다중가설기법을 지도 정합에 도입하기 위하여 GPS/DR 센서 출력 부근의 도로에 대하여 의사 측정치를 정의하였으며, 이를 이용하여 단일 표적문제로 다중 가설 기법을 유도하였다. 가설에 대한 확률식을 유도할 때 GPS/DR 센서 출력뿐만 아니라 디지털 지도의 위상정보가 포함되도록 하였다. 또한 지도 정합 성능의 향상을 위하여 디지털 지도의 바이어스 오차를 보상하기 위한 바이어스 칼만 필터를 제안하였다. 주행 실험결과 제안한 지도 정합법은 도로 밀집지역, 입체도로지역 등 지도 정합이 어려운 지역에서도 우수한 성능을 보였다. This paper presents a map matching method using multiple hypothesis technique(MHT) to identify the road that a land vehicle is located on. To realize a map matching method using MHT, Pseudo-measurements are generated utilizing adjacent roads of GPS/DR position and the MHT is reformulated as a single target problem. Since pseudo-measurements are generated using digital map, topological properties such as road connection, direction, and road facility information are considered in calculating probabilities of hypotheses. In order to improve the map matching performance under when bias errors exist in digital road map data, a Kalman filter is employed to estimate the biases. Field experimental results show that the proposed map matching method provides the consistent performance even in complex downtown areas, overpass/underpass areas, and in the areas where roads are adjacent in parallel.

유백피 추출물의 항세균 작용에 대한 전자현미경적 연구

성태경,이홍용,김치경,Sung, Tae-Kyung,Lee, Heung-Yong,Kim, Chi-Kyung 한국현미경학회 1992 Applied microscopy Vol.22 No.1

Antibacterial effects of the water-soluble extract of Ulmus pumila L. on Staphylococcus aureus and Escherichia coli were studied by cylinder plate dilution method. The cells of S. aureus and E. coli treated with the extract were comparatively examined by scanning and transmission electron microscopies for their morphological features. The normal cells of S. aureus and E. coli showed thypical coccus and rod shapes, respectively, but the cells of S. aureus treated with the extract showed rough surface structures with many granular protrusions and were destroyed to form ghost cells by liberating their cytoplasmic components. E. coli cells treated with the extract were destoryed without enlarging in size and producing granules on their surfaces.
