      • GIS는 국가기간산업부문의 중추

        정진각,Jeong, Jin-Gak 한국정보통신집흥협회 1994 정보화사회 Vol.79 No.-

        태초이래 지도나 지리정보에 대한 관심은 컴퓨터 기술의 발전에 힘입어 GIS를 출현시켰다. 우리나라의 경우 GIS는 지난 78년 서울시 지적과의 지적도 전산화 추진을 시작으로 그 모습을 드러냈지만 지리정보의 전문성 등으로 인해 GIS에 대한 접근이 어려웠다. 이에 최근 쌍용컴퓨터가 성남시에 구축한 '상수도 시설관리전산화'사업을 통해 GIS가 펼치는 세계를 살펴본다.

        1901년 제주민란에 관한 일고 : 소위 신축교난의 발생 원인을 중심으로

        정진각 한양대학교 한국학연구소 1983 韓國學論集 Vol.3 No.-

        The Cheju Revolt at the advent of this century is distinct from other civil uprisings of the late Choson dynasty in that it brought out hundreds of Catholic casualties, raising an international dispute. This revolt has mainly been ascribed to the Japanese residents of that island who perportedly instigated the islanders against the upsurging Catholic influence. This article to be intended reassessing that traditional belief, which an outcome of misunderstandings of the overall international situation around the Korean Peninsula, geographical remoteness of the setting of the island and the misdeeds of the Catholic priests and laymen. Cheju Island, have been under revere had many unfavorable conditions. Its soil was not appropriate for farming and forced most of the islanders to turn to fishing for their living, which was unstable and often risky. Thus the islanders were infested with superstitions and shamanism. The remoteness of the island made it uneasy for the influence of the central government and promoted corruption of the local administrators. Moreover, the 19 th century saw the increasing piracies of the Japanese fisherman. These internal and external exploitation induced the islanders to form an organization to protect themselves and through which to secure their interests. Sangmusa(商務社) was one of them. By 1901, the exploitation of the tax officers (Bongsegwan 捧稅官): became even more relentless and French-supported Catholics added their pillage on the islanders, It was against these exploitation that the islanders, gatheineg around the Sangmusa, uprose. The uprising quickly expanded when the Catholic priests, upon misjudging the situation, invited the commitment of the French Fleet and their followers shot the revolting islanders. This again resulted the bloody mass revenges of the islanders on the Catholics, bringing the casualties from both sides counted over seven hundred. Through the course of the revolt, no evidence of the Japanese residents, involvement is found. Nor could the persistent effort of Lolant Cre´mazy, a French lawyer, prove their commitment. The fact that the Japanese fishermen deserted the already devastated Cheju fishing grounds toward the coast of the Korean Penensula in the end of the 19th century supports the conclusion that there was no involvement of the Japanese. Overshadowed by the name of Religious Ordeal, which emphasizes the victims on the side of Catholics, the reality of the revolt has not hitherto been made clear. Of course, there did exist an element of a Religious Ordeal, in that Catholics had many causalities (that is also a result of unreasonable propagation on their side). But a more important meaning of the revolt should be found in its character as a civil uprising showing the islanders' unity and their spirit of independence, which refuses any foreign power's influence.

      • Aflatoxin B₁多量投與群의 肝中毒發生에 關한 實驗的 硏究 : 組織化學的 所見에 關하여 In the Histochemical Aspect

        鄭鎭恪,崔宗相,白承龍 고려대학교 의과대학 1979 고려대 의대 잡지 Vol.16 No.3

        Aflatoxin is one of the mycotoxins, which can be extractable from some species of Aspergillus flavus, and it may cause acute hepatic periportal necrosis, bile duct proliferation and hepatoma in some animals. The author performed histochemical studies to clarify the effect of Aflatoxin B₁ on the livers of male albino rats weighing about 200 gm. Aflatoxin B₁ dissolved with dimethyl sulfoxide was injected singly into the peritoneum 1㎎/㎏ and 6 ㎎/㎏ to 70 rats. Each experimental group was made of 5 rats and sacrified at 1 day intervals from the first to sixth day after injection. Hematoxylin-eosin, periodic acid schiff, Best's carmine, oil red O, alkaline phosphatase and succinic dehydrogenase stains were performed on frozen and formalin-fixed liver tissues. The results obtained were as follows: 1. The single injectim of Aflatoxin B₁ caused degenerative changes, such as acidophilic degeneration, nuclear pyknosis, vacuolar changes, and focal and periportal necrosis on hematoxylin-eosin stain. 2. The coarse intracytoplasmic granules were diffusely observed in PAS and Best's carmine stains with periportal sparing. 3. The variable sized fat positive granules were noted at the periportal region and extended to mid and central zone of the lobules gradually. 4. The coarse granules which were noted around the periportal area in alkaline phosphatase stain were gradually increased and fine diffuse intracytoplasmic granules were also found. 5. The cells around the periportal areas were positively stained in succinic dehydrogenase staining of the liver of control rats and more deeply stained at the same area of the experimental groups. 6. Those changes were earlier and more prominent in 5 ㎎/㎏ injection group than 1 ㎎/㎏ group, and they seemed to be dose-dependent. In summary, the author considered that aflatoxicosis of rat liver decreases glycogen metabolism, and increases lipid accumulation and the activities of alkaline phosphatase and succinic dehydrogenase.

      • 식물혈구응집소 Ephedra Sinica Stapt가 실혈가토의 조혈기능에 미치는 영향

        정진각,백승룡 최신의학사 1975 最新醫學 Vol.18 No.3

        ESS has been known to possess phytohemagglutinin activity. This study was undertaken to evaluate whether ESS has an effect on hematopoietic activity in rabbit. Every rabbit of experimental group was injected 1.Oml of ESS extract intravenously immediated after bleeding and studied peripheral blood in R. B. C count, hematocrit, hemoglobin, reticulocyte count, total leukocyte count, lymphocyte and granulocyte count. The results obtained are as follow 1. It was noted that R. B. C count, hemoglobin and hematocrit were markedly decreased on the 1st and 2nd day after injection. 2. Previously decreased hematologic data showed tendency to increase from 6th day after injection but it's recovery was delayed. 3. Higher level of peripheral leukocyte count in early stage was noted. 4. Increase of total leukocyte count was due to mainly increased number of lymphocytes and granulocyte in peripheral blood. 5. As the result of those observation, it can be stated that ESS seems to delay the erythropoietic activity but it seems to have potency to inerease in peripheral lymphocyte at earlier stage.

      • Sick Sinus症候群 6例에 關한 考察

        曺局泫,鄭鎭珏,吳鉉觀 順天鄕大學校 1979 의대논문집 Vol.4 No.-

        Six cases of sick sinus syndrome were presented and relevent literature were reviewed. Their electrocardiographic findings were revealed Tachycardia-Bradycardia syndrome (l patient), chronic persistent atrial fibrillation(2 patients), chronic persistent bradycardia (2 patients), and A-V junctional bradycardia, Above abnormal electrocardiographic findings were no changed after medical provocation test with atropine and isoproterenol. Prominent clinical symptoms were dizziness, syncope and their underlying diseases were hypertension, valvular heart disease, myocardiopathy and chest trau'na. Prognosis of presented cases was favorable in 4 cases with medical therapv but 2 cases were not controlled. 1912年 Cohn等은 發作性 心房細動과 一時 心停止로 因한 Stokes-Adams 症候가 있는 患者에서 Sick sinus 症候群을 처음 報告란 이래 臨未心傳導學, 心導子法 및 His束電圖의 發達로 從來에는 單純한 慢生 徐脈 또는 心房細動等으로 看過하기 쉬웠던 本 疾患이 臨床的으로 重要視되게 되었다. 特히 最近에는 心筋內의 電氣生理學的現象 및 刺戟傳導에 對한 새로운 槪念이 導入되면서는 本症의 原因이 되는 洞房結節의 機能異常에 對한 病因, 病態生理 等이 밝혀짐으로 해서 診斷과 治療 및 患者管理面에서 큰 進展을 가져오게 되었다. 著者等은 最近 本病院 內科 心電圖室에서 Sick Sinus症候群로 思料되는 患者 6例를 經驗하고 各 症例들의 基底疾患 및 臨床經過等을 觀察하였기에 報告하는 바이다.
