부산지역 무균성 뇌막염 원인 바이러스의 분리 및 동정 : 1998년을 중심으로
김영희,정영기,김기순,지영미,윤재득,김병준,구평태,민상기,정구영,김만수,조경순 동의대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.10 No.1
The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Resistance of Free-living Stages of Soil-transmitted Parasites of Pesticides
Soh, Chin-Thack,Lee, Keun-Tae,Cho, Kee-Mok,Ahn, Yung-Kyum,Kim, Sang-June,Chung, Pyung-Rim,Im, Kyung-Il,Min, Hong-Ki INSTITUTE OF TROPICAL MEDICINE YONSEI UNIVERSITY 1975 YONSEI REPORTS ON TROPICAL MEDICINE Vol.6 No.1
消化器系寄生蟲 卵子, 幼蟲, 및 씨스트의 數種農藥에 對한 抵抗力을 調査하였다. 寄生蟲은 犬鈞蟲, 東洋毛樣線蟲의 卵子 및 幼蟲, 蛔蟲, 鞭蟲의 卵子, 痢疾아메바「씨스트」였고, 農藥은 現在 韓國에서 가장 널리 使用되고 있는 殺菌劑(Captan, Polyramcombi), 殺蟲劑 (Diazinon, B.T.C., Hepta) 및 除草劑(Simazin, P.C.P.)等 數種을 採擇하였으며 使用農藥의 濃度는 實際 農村에서 適用되고 있는 用量을 參酌하였다. 寄生蟲 幼蟲에 對한 農藥 露出時間은 24時間까지로 하였으나 必要에 따라 48時間까지도 延長하였다. 農藥別 殺蟲效果는 다음과 같다. Captan : 鈞蟲卵子는 2培稀釋量(2:400)에서 2時間內에 死滅하였고, 其他 蟲卵에 對하여는 殺卵效果가 없었다. 痢疾아메바「씨스트」는 6時間內에 完全死滅하였다. 鈞蟲 및 東洋毛樣線 幼蟲에 對해서는 24時間內에 뚜렷한 殺蟲效果를 볼 수 없었다. Polyramcombi (1 : 800) : 모든 實驗 線蟲類 卵子 및 幼蟲 그리고 痢疾아메바「씨스트」에 對한 顯著한 殺蟲效果를 볼 수 없었다. Diazinon (1 : 800) : 鈞蟲卵子 만이 2培稀釋量(2 :800)에서24時間內에 死滅되었으며 其他 蟲卵에 對한 殺蟲效果를 없었다. 鈞蟲 rhabditoid 幼 은 12時間內에, 痢疾아메바「씨스트」는 1時間內에 死滅되었다. B.T.C. (30mg/50cm²) : 蟲卵 및 痢疾아메바「씨스트」에 對한 殺滅效果는 없었고, 鈞蟲卵子는 2培 稀釋量 (2×30mg/50cm²)에서 24時間內에 死滅하였다. 鈞蟲 rhabditoid 幼蟲은 12時間內에 完全死滅하였으나 被襄幼蟲은 그 50%가 生存하였다. Hepta (30mg/50cm²) : 實驗蟲卵 및 痢疾아메바「씨스트」에 對해서는 殺滅效果가 없었고東洋毛樣線蟲 rhabditoid 幼蟲만이 露出 12時間에 死滅되었다. Simazin (0.5mg/50cm²) : 蟲卵 및 痢疾아메바「씨스트」에 對한 殺滅效果는 없었고, 東洋毛樣線蟲 被襄幼蟲만이 露出 12時間에 死滅되었다. P.C.P. (5mg/50cm²) : 鈞蟲卵子만이 2培稀釋量 (2×5mg/50cm²)에서 24時間內에 殺卵되었을 뿐 其他 試供蟲卵에 對한 殺卵效果는 없었다. 鈞蟲 rhabditoid 幼蟲은 24時間內에, 被襄幼蟲은 48時間內에 死滅되었고, 東洋毛樣線蟲 rhabditoid 幼蟲 및 被襄幼蟲은 露出 6時間內에 死滅되었다. 痢疾아메바「씨스트」는 露出 3時間以內에 完全 死滅되었다. 以上의 結果로 보아 常用農藥은 犬鈞蟲, 東洋毛樣線蟲, 蛔蟲, 鞭蟲卵에 對한 殺蟲效果는 없었고 Diazinon, B.T.C., P.C.P., Simazin等의 農藥은 鈞蟲 및 東洋毛樣線蟲의 幼蟲, 特히 第1期 幼蟲 즉 rhabditoid幼蟲의 경우 그 實際適用濃度에서 顯著한 殺蟲效果를 나타내었으며 痢疾아메바「씨스트」는 Captan, Diazinon, P.C.P.와 같은 常用農藥에 對하여 露出 1∼6時間內에 完全死滅됨을 알 수 있었다. Lethal action of pesticides, which are used in present day Korea, to free living stages of hookworm, Trichostrongylus, Ascaris, Tricharis and cyst of Entamoeba histolytica was examined. The pesticides were bactericides (Captan, Polyramcombi), insecticides (Diazinon, B.T.C. and Hepta), and herbicides (Simazin, P.C.P.). The concentration of the pesticides was prepared on the basis of practical application in field. The routine period of exposure was 24 hours, and the results are briefly summarized as below ; Captan (1 : 400) : No lethal action to the eggs tested was destroyed within 24 hours at the 2-fold concentration. Entamoeba histolytica cysts were destroyed within 6 hours. Polyramcombi (1 : 800) : No significant lethal action was appeared to eggs and larave, and cysts of E. histolytica. Diazinon (1 : 800) : No lethal action to the eggs tested was destroyed within 24 hours at the 2-fold concentration. The rhabditoid larvae of hookworm were killed within 12 hours, and cysts of E. histolytica within one hour. B.T.C. (30mg/50cm²) : No lethal effect was confirmed to eggs, and cysts of E. histolytica tested. Hookworm eggs were destroyed at the 2-fold concentration within 24 hours. Hookworm rhabditoid larvae were killed within 12 hours, but the filariform larve survived 56% at the same period. Hepta (30mg/50cm²) : No lethal effect was proved to eggs, and cysts of E. histolytica tested. Rhabditoid larvae of Trichostrongylus were destroyed within 12 hours. Simazin (0.5mg/50cm²) : No lethal effect was proved to eggs, and cysts of E. histolytica tested. Filariform larve of trichostrongylus only were destroyed within 12 hours. P.C.P. (5mg/50cm²) : No lethal effect was proved to eggs, but hookworm eggs were destroyed within 24 hours at the 2-fold concentration. The rhabditoid larvae of hookworm were destroyed within 24 hours, and the filariform larvae within 48 hours. The rhabditoid and filariform larvae of Trichostrongylus were killed within 6 hours. Cysts of E. histolytica were destroyed within 3 hours. The overall results indicate that the conventional pesticides show no significant lethal effect to the eggs of hookworm, Trichostrongylus, Ascaris and Trichuris. But the larval forms specially the rhabditoid forms of hookworm and Trichostrongylus, will be destroyed either by Diazinon, B.T.C., P.C.P. and Simazin at the ordinary concentrations of the field application. Entamoeba histolytica cysts also will be destroyed by Captan, Diazinon and P.C.P. within 1-6 hours.

In this paper we have developed an image security system based on Internet Web in order to overcome the problem of existing systems that use the dedicated network. The developed system resolves the safety problem of the centralized control model by adapting the distributed control model based on Web, and has the functions of remote control and automatic monitoring for grouped multiple sites on remote Web browser. And the system can operate various computers or operating system because it' s operating software was designed by the concepts of Java Virtual Machine and Virtual Instrument. Also, our system has not need of additional cost for network construction by using Internet and can greatly improve the managemental efficiency of system because the maintenance and publishing of software updates can be performed through Web Server.
