박영우 광주보건대학 1990 論文集 Vol.15 No.-
Their relations to the slow erythrocyte sedimentation rate (ESR) of the ruminants were investigated by treating the erythrocytes with proteinases such as trypsion, chymotrypsin and pronase, and glycosidases neuraminidase and galactosidase. Protein content in the erythrocyte membrane was 2.85 ± 0.28 in human, 3.60 ±0.41 in Korean cattle, 3.71 ± 0.36 in Holstein, 4.13 ± 0.83 in Korean native goat and 3.94 ± 0.56mg/ml in sheep, showing higher in ruminant animals than in human (p<0.01). In the erythrocyte treated with the enzymes, ruminants except sheep was better digested by proteinases than by glycosidases, showing remarkable increase ( p<0.01) of the ESR in accord by pronase, trypsin or chymotrypsin treatment of erythrecytes. In sheep, the ESRs were accelerated in erythrocytes treated with pronase, trypsin, chymotrypsin and neuraminidase. Erythrocyte osmotic fragility was ncreased in erythocytes treated with only pronase among five enzymes in all the human and ruminant animals used in this study.

Li^+이온이 주입된 D_2O 얼음의 열자극 발광 현상에 관한 연구
박영우,황정남,이철주 연세대학교 자연과학연구소 1987 學術論文集 Vol.19 No.-
저온에서 편극시킨 탈이온수 얼음의 열자극 편극 소거 전류(Thermally Stimulated Depolarization Current ; TSDC)를 77K∼250K 범위에서 측정하여 Li^+ 이온이 주입된 D_2O 얼음의 이온공간전하 열자극 전류(Ionic Space Charge Thermocurrent ; ITC)와 열자극 발광(Thermoluminescence ; TL)을 측정하였다. D_2O 얼음의 TSDC인 경우는 173K에서 heterocharge가 나오고 200K에서 homocharge가 나온다. 이 때 heterocharge는 1차 kinetic임을 알았고, initial rise법으로 구한 활성화에너지는 0.16eV이다. D_2O 얼음의 heterocharge는 bulk에 의한 효과이고, homocharge는 공간전하에 의한 TSDC임을 확인하기 위하여, 가속기를 이용해 Li^+이온을 주입시킨 D_2O 얼음의 TL을 조사해본 결과 114K(A-peak), 180K(C-peak)에서 3개의 TL peak가 형성되는데 각각의 활성화에너지는 0.03eV, 0.15eV 및 0.29eV이다. 이중에 B-peak의 활성화에너지 값과 거의 일치하여 그 결과로 부터 B-peak의 근원이 이온공간전하에 의한 쌍극자 재정렬임을 최초로 확인하였다. Thermally stimulated depolarization current(TSDC) has been measured in distilled and deionized water ice in the temperature range of 77∼250K at a constant heating rate, and the ionic space charge thermocurrent(ITC) and thermoluminescence(TL) has been measured from Li^+ion implanted D_2O ice. In the case of TSDC of D_2O ice, the heterocharge give rise to 173K, while the homocharge give rise to 200K TSDC peak. The heterocharge peak TSDC is found to be 1st kinetic and that the activation energy is o.16eV using the initial rise method. In order to investigate that the heterocharge is due to the polarization in the D_2O ice and the homocharge due to the ionic space charge, TL curve from Li^+ion implanted D_2O ice and the homocharge due to the ionic space charge, TL curve from Li^+ion implanted D_2O ice shows three peaks at 114K, 148K and 183K. The activation energy for these TL peaks are 0.03eV, 0.15eV and 0.29eV, respectively. The activation energy for B-peak(0.16eV) is coincide with that of ITC peak which means that both TL peak and ITC peak are caused by the dipole reorientation due to ionic space charge. This approach to clarifies for the first time to my knowledge.

朴寧雨 慶北大學校 醫科大學 1982 慶北醫大誌 Vol.23 No.2
Reye 症候群의 腦波所見을 硏究하기 위해 1979년 12월부터 1982년 12월까지 慶北醫大附屬病院 腦波檢査室에서 腦波檢査를 實施한 이 症候群 患兒 8名의 腦波記錄과 그들의 臨床資料를 調査分析했던바 그 結果를 要約하면 다음과 같다. 腦波檢査를 實施한 8名中 5名에서 異常腦波를 나타냈는데, mild abnormality가 2名, moderate abnormality가 2名, marked abnormality가 1名이 었다. 그리고 異常腦波의 異常程度가 marked abnormality 또는 이보다 좋게 분류됐던 모든 患兒들은 완쾌되거나 호전되어 생명을 건졌다. clinical seizure는 이 急性疾患의 경과중 아주 빈번했다. 그러나 독특하게도 clinical seizure는 있었지만 epileptiform discharge의 發顯은 없었다. 그외 암모니아혈중농도, 肝기능, 뇌척수액압등은 EEG 변화와 뚜렷한 상관관계가 없었다. 아울러 장차 EEG on-line monitoring과 콤퓨터分析을 施行한다면 강력한 치료를 이 症候群의 어느 시기에 시작하는 가를 결정하는데 상당한 도움이 될 것으로 사료된다. In order to study EEG findings in Reye's syndrome, the EEG records in relation with clincal data in 8 children who had been diagnosed as Reye's syndrome were analized. The selected examinee were those who had been taken EEG examination at Kyungpook National University Hospital during the hospitalization periods from Dec. 1979 to Dec. 1982. Out of total eight cases, five showed abnormal EEG; mild abnormality in two, and marked in one. All patient whose EEG was classified as marked abnormality or above survived. In seven cases, seizures were common during the courses of their illnesses. But, curiously, the athor could find little temporal correlation between clinical and electrographic seizures in seven cases. Blood ammonia, liver function, and CSF pressure were not closely correlated with the EEG changes. In the future, EEG on-line monitoring and computerized evaluation will likely be useful for aggressive therapeutic intervention.

인터넷상에서의 정보 검색을 위한 사용자 적응형 필터링 방법에 관한 연구
박영우,이은석 成均館大學校 科學技術硏究所 1998 論文集 Vol.49 No.2
It is very difficult for search engines to find the adequate information, which reflects user's interests that are changing with time on Internet. We need various learning techniques to know the user's interests with only given simple query, and to make adaptive Information Retrieval Agents. In this paper, we propose a learning mechanism that can be used in making it easier the user profile from accepted relevant documents' terms. These documents are proposed by the user's relevance feedback and we select key-terms in the documents for making profile. With using this profile, we can filter the retrieved information and represent more relevant information to user. This approach has applied to an autonomous information gathering and filtering system, named IGIMA (Intelligent Information Gathering and Filtering System based on Multi-Agent).
