전기화재방지를 위한 도체의 최소 굵기와 단락전류, 온도특성 모델링
신동열(Dong-Yeol Shin),조종은(Chong-eun Cho),정종만(Jong-Man Joung) 대한전기학회 2021 대한전기학회 학술대회 논문집 Vol.2021 No.7
전력 설비의 용량과 수명은 주로 도체와 절연체의 온도와 지속시간에 의해 의하여 결정된다. 전기화재는 절연물의 열화, 도체의 용량 부족에 의한 발열 등에 의해 발생 된다. 전기화재방지를 위해서는 용량과 온도, 수명과 열량에 대한 이해가 필요하다. 눈에 보이지 않는 전기 에너지[J]와 눈에 보이는 설비 열량[J]은 발열과 방열에너지로 상호 연결되어 있다. 전력 설비를 안정적으로 관리하기 위해 전선의 굵기, 허용전류, 허용시간, 절연물의 허용온도에 대해 이론적 개념과 3가지 유형별 사례를 모델링하고 결과를 검증하였다.

Objectives : This study was designed to evaluate the effects of traditional oriental therapies(TOT) on advanced gastric cancer(AGC) patient with metastasis to liver. Methods : We retrospectively analyzed the medical record of a case of AGC patient in stage IV with metastasis to liver who had been treated with TOT for 5 months continuously in East-West Cancer Center of Oriental Hospital of Daejeon University from 5 March 2003 through 22 July 2003. Results : After treated with TOT for the 5 months, most of symptoms were disappeared or improved and tumor size was decreased on abdominal CT compared with the previous result. The hematological results and tumor markers were not increased. Conclusions : From the above results, it could be suggested that TOT have effects on improving symptoms and quality of life as a supportive or curative therapy for AGC patients.
Pentazocine과 Morphine에 依한 組織內 Catecholamine 含量 및 血漿 Corticosterone變動에 對한 Naloxone의 影響

Opioids-induced analgesia is due to actions at several sites within the CNS and involves several systems of neurotransmitters. In this paper, the influences of naloxone on the changes of brain and cardiac norepinephrine(NE) contents and plasma corticosterone induced by pentazocine and morphine in mice were studied. The results obtained were summarized as follows: 1. Brain and cardiac NE contents were markedly decreased by 60㎎/㎏ of pentazocine given intraperitoneally, but not affected by 30㎎/㎏ and 60㎎/㎏ of pentazocine given. 2. Brain and cardiac NE contents were markedly decreased by 20㎎/㎏ of morphine given intraperitoneally, but not affected by 10㎎/㎏. And plasma corticosterone levels were markedly increased by 10㎎/㎏ and 20㎎/㎏ of morphine given. 3. Naloxone antagonized the decreases of brain and cardiac NE contents induced by pentazocine, but not antagonized the increases of plasma corticosterone levels. 4. Naloxone completely antagonized the decreases of brain and cardiac NE contents and increases of plasma corticosterone levels induced by morphine. 5. Brain and cardiac NE contents were markedly decreased and plasma corticosterone levels were markedly increased by intraperitoneal injection twice daily for 7days of pentazocine in increasing doses from 30 to 60㎎/㎏ per injection, and naloxone did not antagonized, the changes of tissue NE contents and plasma corticosterone levels induced by pentazocine. 6. These changes in tissue NE contents and plasma corticosterone levels were no longer seen by intraperitoneal injection twice daily for 7days of morphine in increasing doses from 10 to 20㎎/㎏ per injection.
