Purpose: To describe the chest radiographic findings of acute paraquat poisoning. Materials and Methods: 691 patients visited the emergency department of our hospital between January 2006 and October 2012 for paraquat poisoning. Of these 691, we identified 56 patients whose initial chest radiographs were normal but who developed radiographic abnormalities within one week. We evaluated their radiographic findings and the differences in imaging features based on mortality. Results: The most common finding was diffuse consolidation (29/56, 52%), followed by consolidation with linear and nodular opacities (18/56, 32%), and combined consolidation and pneumomediastinum (7/56, 13%). Pleural effusion was noted in 17 patients (30%). The two survivors (4%) showed peripheral consolidations, while the 54 patients (96%) who died demonstrated bilateral (42/54, 78%) or unilateral (12/54, 22%) diffuse consolidations. Conclusion: Rapidly progressing diffuse pulmonary consolidation was observed within one week on follow-up radiographs after paraquat ingestion in the deceased, but the survivors demonstrated peripheral consolidation. 목적: 급성 파라쿼트 중독증 환자에서 흉부 X-선 사진 소견을 기술하고자 한다. 대상과 방법: 2006년 1월에서 2012년 10월까지 파라쿼트 중독증으로 본원 응급실로 내원한 691명 중 흉부 X-선 사진에서 내원 당시에 정상 소견을 보였다가 1주 이내의 추적 검사에서 이상 소견을 보인 56명을 대상으로 흉부 X-선 사진 소견을 분석하였다. 흉부 X-선 사진의 이상 소견의 빈도 및 생존자와 사망자 간의 영상 소견의 차이가 있는지를 평가하였다. 결과: 미만성 경화의 형태가 가장 흔한 이상 소견이었으며(29/56, 52%), 미만성 경화와 동반하여 선음영, 결절성 음영을 보이는 경우(18/56, 32%)와 미만성 경화와 종격동기종의 동반 형태를 보이는 경우(7/56, 13%)가 그 다음으로 흔하였다. 흉막삼출은 17명(30%)에서 관찰되었다. 총 56명의 환자 중 생존자 2명(4%)은 흉부 X-선 사진에서 주변부 경화를 보였으나, 사망자 54명(96%)은 양측성(42/54, 78%) 또는 일측성(12/54, 22%) 미만성 경화를 보였다. 결론: 파라쿼트 음독 후 추적 관찰한 흉부 X-선 사진에서 사망자는 1주 이내에 급격하게 미만성으로 진행하는 이상 소견을 보였으며, 생존자는 주변부 경화의 형태를 보였다.

羅庚均 圓光大學校大學院 1990 論文集 Vol.5 No.-
Harmonized with the nature sharing in the benefic of it, human life has been developed within the providence and the order of nature. But in the process of economic growth and social development which is followed increasing the population and progressing the science, human being has taken the serious problems that original nature of environment is not recovered by its purification power over the pollution. So, the ervironmental pollution has become the threat to the individual health and the environmental destuction, and the menace to the existence of human being. In the past, environmental pollution was so small that it was not a matter owing to the self-purification power. But now it is common problem of all human being facing the danger in which we meet the destruction of environment and the pollution of non-existing degree. Therefore, human being are stated the sufferer who is injured by the environmental circulation law, not the mere environmental benefactor. I studied, in this thesis, the various problems or the environmental right of its meaning and generative background, its base, its qualities and effects, its injure and legal rescue, and so on.

조기 유방암에서 수술 전 유방초음파 및 유방 자기공명영상검사와 수술 후 병리학적 종양 크기에 대한 비교 연구

Purpose: Preoperative tumor size is associated with clinical stage, treatment plan and even survival rate of patient. We investigated the accuracy of tumor size estimation between magnetic resonance imaging (MRI) and ultrasonography (US) findings, comparing these with pathologic tumor size in the diagnosis of early breast carcinoma. Methods: Between 2011 and 2016, 136 patients with early breast cancer were analyzed and their tumor size on US and MRI findings were compared with their pathologic tumor size retrospectively. The background parenchymal enhancement of MRI was categorized as minimal, mild, moderate, and extreme. The patients who underwent neoadjuvant chemotherapy, had positive resection margins, underwent excisional biopsy for cancer diagnosis, and had non-mass lesions on MRI scans, were excluded. Results: In all, 83.1% of the cases showed concordance between MRI findings and pathologic tumor size within 0.5cm. MRI overestimated the findings by 10.3% and underestimated them by 6.6%; 78.7% showed concordance between US findings and pathologic tumor size within 0.5cm. US overestimated the findings by 5.9% and underestimated them by 15.4%. The tumor size on MRI (r=0.87) showed a stronger correlation to the pathologic tumor size than that on US (r=0.64) in early breast cancer patients. US had a tendency to underestimate the tumor size. The degree of breast parenchyma did not affect the accuracy of the measurement of preoperative tumor size. Conclusion: MRI is relatively more accurate than US for assessing preoperative tumor size in breast cancer patients. US tends to underestimate tumor size.
