LiCl-KCl 공융염 (450 ℃) 내에서 Armco 철의 부식에 대한 산소의 영향
박녕우,윤승열 대한금속재료학회(대한금속학회) 1981 대한금속·재료학회지 Vol.19 No.7
Effect of oxygen on the corrosion of Armco iron in molten LiCl-KCl eutectic salt at 450℃ was studied by electrochemical techniques. All the experimental work was carried out in an inert atmosphere glove box, equipped with a specially designed electrolysis cell system. Results clearly showed the existence of active-passive transition for Armco iron corrosion in the melt and also the dependence of corrosion rate and potential upon the oxygen limiting diffusion current. Above 0.25V of electrode potential refered to Ni/Ni₃S₂/S^(--) reference electrode, main partial anodic reaction appeared to be Fe →Fe^(+3)+3e and showed clear Tafel linearity with slope of about 80 mV/dec. Corrosion rate was increased in proportion to 1/5 power of oxygen partial pressure. Other electrochemical parameters related to the corrosion reaction were also discussed based on the mixed potential theory and electrode kinetics.

小兒癎疾 患者에서 몇 가지의 臨床的 要因과 腦波所見과의 關係를 알아 보기 위해 1973年 2月부터 1976年 12月까지 慶北醫大附屬病院 腦波檢査室에서 原因 不明의 痙攣發作 때문에 腦波檢査를 실시한 15歲以下의 小兒患者 267名의 腦波記錄과 그들의 臨床資料를 調査分析했던 바 그 結果를 要約하면 아래와 같다. 267名의 全腦波記錄中 175名(65.5%)의 腦波記錄이 異常腦波 所見을 보였다. 異常腦波의 發顯率은 3-6歲의 年齡群에서 71%로 가장 높았고 3歲 以下의 年齡群이 55%로서 제일 낮았다. 男兒에 비해 女兒의 異常腦波 發顯率이 有意하게 높았고 年齡別로는 7-9歲群에서 女兒가 男兒에 비해 有意하게 높은 發顯率을 보였다. 異常腦波의 波形은 徐波 單獨만 볼 수 있는 것이 가장 많았고 다음으로 여러 가지 波形이 混在하는 것, isolated spike만 있는 것, spike & wave만 보이는 것 等의 順으로 많았다. 異常腦波를 보인 全對象中 異常波의 發顯部位가 局所性인 것이 43%, 全般性인 것이 역시 43%, 焦點性인 것은 14%였으며, 6歲以下의 低年齡群에서는 全般性인 것이 많고 7歲 以上의 高年齡群에서는 局所性인 것이 有意하게 많았다. 異常腦波의 出現部位는 前頭部가 57%로서 단연히 많았고 側頭部와 頭頂部가 各各 16% 後頭部가 11%의 順으로 많았다. 低年齡群에서는 程度가 심한 異常腦波가 많았고, 高年齡群에서는 輕度의 異常腦波가 有意하게 많았다. 發作의 頻度, 마지막 發作後 腦波檢査施 까지의 時間 經過의 長短, 抗痙攣劑의 服用 如否等은 異常腦波의 發顯率, 發顯範圍, 異常程度 等에 그다지 예민하게 反映된다고 볼 수 없었다. In order to determine the factors affecting EEG findings in childhood epileptics, the EEG records and clinical data in 267 children who had the episodes of convulsive seizure of unknown causes were analysed. The selected examinees were those who had been taken EEG examination at Kyungpook National University Hospital during the period of 1973-1976. Out of the total 267 cases 175(65.5%) showed abnormal EEG. The incidence of abnormal EEG stood highest in the age group under 3years (55%). The incidence of abnormal EEG in females was significantly higher than that in males, especially in the age group of 7-9 years. In the wave patterns of abnormal EEG, the most frequently encountered was slow waves, and followed by the mixture of various wave patterns, isolted spikes, spike and wave in the order of lesser frequency. The extent of abnormal waves was 43% for generalized, 43% for localized, and 14% of focal; the proportion of generalized abnormalities was significantly higher in the younger age group than in the older group, whereas in the older age group localized abnormalities were conspicuously greater in proportion. The frontal area was most frequent site of localization (57%), and next came temporal, parietal, occipital area in the order of decreasing frequency. In the degree of EEG abnormality with regard to age group, the proportion of severe abnormality in the younger group was prominently higher than that in older group. It seems likely that the frequency of seizure, the time elapsed from last seizure to EEG tracing, and anticonvulsant medication failed to have a sensitive influence on the degree, extent and incidence of abnormal EEG.
