          Diagostic imaging can help in management of toxicologic emergencies. We report a patient who presented to the emergency department with coma and suppressed respiration after ingestion of unknown substance. We documented chloroform with radiopaque material in bowel on abdominal radiograph. We used activated charcoal and laxative to decontaminate bowel. Hepatotoxicity occurred on 3rd admission day and elevation of liver enzyme reached peak level on 5th admission day. The patient received hemoperfusion, N-acetylsystein and supportive cares. The patient was improved from hepatic dysfunction and discharged without complication on 11th admission day. Radiograph in toxicology may confirm a diagnosis and assist in therapeutic intervention.

          心巖 金志洙의 思想과 自決殉國

          이성우(Lee, Sung-woo) 호서사학회 2015 역사와 담론 Vol.0 No.76

          자결순국은 가장 적극적이고 극단적인 항일투쟁이었다. 유학자들은 일제의 침략에 맞서 자결로써 항거했다. 김지수는 일제의 은사금을 거부하고 자결한 순국지사이다. 김지수는 충남 연산출신으로 사계 김장생의 11대손이었다. 김장생은 조선 예학의 종장으로 당대 최고의 山林으로 존숭받았으며, 그의 사상은 김집, 송시열, 한원진으로 계승되었다. 따라서 김지수는 가문에 대한 자부심이 강했다. 김장생, 김집으로 이어지는 예학의 종장을 배출한 가문 출신이라는 점이다. 따라서 그의 학문은 家學인 禮學에 기반을 두고 있었다. 김지수는 族親 金永膺으로부터 많은 영향을 받았으며, 그와의 관계로 杞菊亭 講會와 亦樂齋契에 참여하면서 宋近洙ㆍ宋秉璿ㆍ宋秉珣 등과 교류하게 되었고 송시열의 사상을 습득했다. 그는 지역 유학자들과 교유하기 시작하면서 연산지역에서 학계를 조직해 유림들을 결속하고 가문의 위상을 정립하는 활동을 벌여나갔다. 이러한 활동을 기반으로 관계에 진출했으나 곧바로 사임하고 은둔자정의 길을 선택했다. 김지수는 1911년 일제가 소위 은사금을 보내오자 절명시를 남기고 자결했다. 일제에게 욕을 당하느니 차라리 정도를 지키겠다는 것이었다. 그는 김장생의 예학을 계승했고 유학의 효용성과 절대적 진리를 신봉하고 있었다. 그에게는 의리와 대의명분을 지키는 것이 바로 ‘禮’였다. 그는 자결순국으로 자신의 학문인 예학의 義理를 실천한 것이었다. 이러한 특징은 그의 문인들도 같았다. 송병선․송병순․이학순은 일제의 침략에 맞서 자결순국한 대표적 유학자이다. 송병선은 을사늑약에 항거해 자결했고 이학순과 송병순은 은사금을 거부하고 자결했다. 이들은 ‘金長生-金集-宋時烈-權尙夏-韓元震-宋能相-宋煥箕-宋穉圭’로 이어지는 기호학통을 계승하고 있었다. 따라서 자결순국을 통해 학문적 전통과 신념, 문인에 대한 의리, 유학적 가치와 질서를 지키기 위해 자결의 길을 선택했던 것이다. Kim Ji Su sacrificed his life for the country and rejected to receive the Japanese Empire’s royal bounty. He was born at Yeonsan, Chungnam Province, and a great grandson of Kim, Jang Sang. Kim, Jang Sang was a master of 예학 in Chosun and respected as a San-lim of the day. His thought was succeeded to Kim, Jip, Song, si Yeol and Han, Won Jin. Thus, Kim, Ji Su had much pride in his family and his studies was based on the Yehak Kim, Ji Su was influenced by one of his relatives, Kim, Young Woon, and interchanged experience and learned the thought of Song, Si Yeol at the Kigookjeong and Yeoklackjaekae. Interchanging experience with Confucian scholars at Yeonsan area, he was very active at organizing Confucian scholars and set up his family’s status. Through these activities, he became a government official, but resigned immediately and lived in seclusion. In 1911, when the Japanese Empire gave a royal bounty, he committed suicide leaving a poet. He succeeded Kim, Jang Sang’s Yehak, and believed in the usefulness of the Confucianism and absolute truth. For him, Ye was the fidelity, and just and great cause. He put his thought and theory into practice by committing suicide. With him, Song, Byong Sun, Song, Byong Soon, and Lee Hank Soon who succeeded Kiho School, also committed suicide against Japanese invasion. Song, Byong Sun committed suicide against the Protectorate Treaty between Korea and Japan concluded in 1905. Song, Byong Soon and Lee Hank Soon committed suicide rejecting the Japanese Empire’s royal bounty. They chose to commit suicide for their academic tradition and beliefs, fidelity to scholars, the Confucian values and order

          Daehoji Samil Movement was a large scale Manse{Hurrah]demonstration in which about 1,000 people participated. This demonstration was thoroughly prepared by the townspeople living at Daehoji, and they staged a Manse demonstration marching to Cheonui marketplace at Jeonngmi-myeon on April 4, using Oiljang[market held every five days]. Such data that can prove the Samil Movement at Daehoji is mostly from the imperialist Japan and this research look into these data centering on telegrams, reports, written judgements, one's personal records collected at the Seodemun Prison. There are some cases where the contents of the imperialist Japan's telegrams transmitted at the time of a demonstration are different from those of the reports written up after a demonstration and also the statistics about a demonstration vary according to reporting agencies and a point of time. However, the imperialist Japan oppressed a demonstration by force of arms immediately after it happened by dispatching 8 police officers and 5 guards, arresting 21 participants in the demonstration until the 6th day, or two days after the demonstration. In addition, this research could make certain of the imperialist Japan's harsh suppression on the basis of the fact that on April 8 demonstration, where only 70 people from Jokeum-ri, and 80 people from Songjeon-ri rose against the imperialist Japan, they perpetrated firing guns at the demonstrators, causing patriotic deaths on the spot. There still remain written judgments for those who were indicted for participating in the demonstration while staging a court struggle, and personal records for those at the Seodaemun Prison where they were imprisoned. Through the written judgment for Min, ]ae-bong which was newly discovered, this research could find out new facts on the preparatory process for the demonstration centering on the Daehoji-myeon office. In addition, through the personal records for Lee, In-jeong, Nam, Sung-wu, Kim, Yang-chil, and Song, Jae-man who were imprisoned at the Seodaemun Prison, this research looked into the date for the court decision, releas from prison, and the beginning of sentence execution, etc.

          이성우,정태화,최강원,임정기,이덕형,Lee, Sung-Woo,Chung, Tae-Wha,Choe, Kang-Won,Lim, Jung-Ki,Lee, Duk-Hyoung 대한예방의학회 1989 Journal of Preventive Medicine and Public Health Vol.22 No.4

          In a small island community with a population of less than 100 residents, nine persons died and five experienced severe illnesses during the period from November 1986 to May 1988. Their initial symptoms were sore throat and fever. Renal failure and hepatitis developed within one week after the onset. Oral mucosal ulcer developed in some cases. After one week, progressive respiratory failure and dyspnea developed evidently and severe respiratory distress and hypoxia preceded those fatal cases. Chest X-ray findings revealed bilateral diffuse multiple cystic lesion with occasional multiple large emphysematous bullae. Based on these features paraquat poisoning was diagnosed and route of poisoning was investigated. In three sources of drinking water, trace amount of paraquat was detected in November 1988, six months after the incidence of recent fatal case. In November 1988, soybean sauces and soybean pastes from 12 households were found contaminated with high concentration of paraquat, the cause could not be identified. The possibility of the contamination of drinking water as the cause of this mass poisoning has been suggested.

          유한요소법(有限要素法)을 이용한 철근(鐵筋)콘크리트 슬래브의 설계(設計)모멘트 산정에 관한 소고(小考)

          이성우,Lee, Sung Woo 대한토목학회 1988 대한토목학회논문집 Vol.8 No.3

          철근(鐵筋)콘크리트 슬래브를 설계(設計)하기 위해서는 우선 정확한 2방향(方向) 설계(設計) 모멘트가 산정되어야 한다. 이를 위해 본(本) 연구(硏究)에서는 등매개(等媒介) 평판요소(平板要素)를 사용하는 유한요소법(有限要素法)을 제안하였다. 사면 단순지지 슬래브에서 이 요소(要素)를 이용한 해(解)를 탄성평판(彈性平板) 이론치(理論値)와 비교한 결과 전지간에 걸쳐 좋은 결과를 얻었다. 또한 flat plate 에서 종래의 방법(方法)인 등가뼈대법(法)으로 해석(解析)한 결과와 한 방향(方向)에 대해 비교검토 하였다. 특히 등가뼈대법(法)에서 총모멘트를 시방서(示方書)의 계수(係數)를 써서 설계(設計)폭에 분배한 결과가 불합리한 것으로 지적되었다. 반면 같은 정확한 2 방향(方向)모멘트를 구할 수 있었다. 제시된 방법(方法)은 슬래브 시스템의 어떠한 기하학적 구조(構造)에도 적용할 수 있어서 종래의 방법(方法)보다 훨씬 유리한 개선된 설계방법(設計方法)임을 알 수 있었다. Evaluation of accurate design moments in two directions is a primary concern in designing R/C Slab. For this purpose, the use of finite element method utilizing isoparametric plate element is proposed. An example of the simply supported slab shows that the results agree well wth those from elastic plate theory throughout the span. The finite element solutions are also compared with those from equivalent frame method in a flat plate example. It is indicated that the distribution of total moment through the width of design strip using the ACI coefficients is unreasonable. In contrary to this, for the same strip model, the finite element method gives accurate moments in two directions. The proposed method can be applied to any geometric configuration of the slab system, thus the approach is considered to be much advantageous and improved one compared with existing methods.
