( Seong¸ Shin Hyung ) 한국윤리학회(구 한국국민윤리학회) 2020 倫理硏究 Vol.131 No.1

Based on Emmanuel Levinas and Simone Weil, this examines moral agency the relation between self and outside of self. Levinas criticizes the Heideggerian ontology that is limited to the subject-centered relationship, resulting in the collapse of human relationship. He argues that humanity focus on the existential and phenomenological condition that there are others outside of self makes people act ethically. Second, Simone Weil begins her thoughts from her experience of affliction and develops into thoughts of morality acknowledge as she acknowledges her acceptance of affliction from a distance, the gravity of the world and grace of God and the love of neighbor. Thus, this study demonstrates that humanity can become a moral agency through the new relationship among people, the world and God.

Myelodysplastic syndrome(MDS) is a group of acquired conditions characterized by progressive bone marrow failure associated with normocellular or hypercellular bone marrow that cannot be attributed to nutritional deficiency, chronic infection, or other chronic systemic illness, and cannot be reversed by the successful treatment of those conditions. Whereas the cases of secondary MDS occur at all ages, primary MDS is essentially a disease of elderly, though no age group is exempt and predomonant in men. The MDS is fundamentally clonal disorders at the level of the haemopoietic totipotent stem cell. Clinically, they are characterized by varing degrees of peripheral cytopenia(s) with morphological and functional abnormalities of blood elements. We have experienced two unrelated pediatric cases, who showed pancytopenia on admission and the characteristic marrow findings of MDS. The first case, a 12 months-old girl, showed increased reticulin with abnormal localization of immature precursor cells(ALIP) in her bone marrow, in addition to dysplastic features such as bi-and multi-nucleation of late normoblasts and internuclear bridging. She also showed 22% of blasts in her bone marrow cells thus classified in the category of RAEB-t after FAB classification. Also found were a chromosomal abnormality namely 46 XX t(14q21q), which was an unusual one. Her family brought her home and, 4 month later, she deceased. The second case, a 12 year-old boy, showed pancytopenia with Pseudo-Pelger-Huet anomaly in neutrophils but no blasts in the peripheral blood. Bone marrow of this case also showed the picture of dyserythropoiesis with binuclearity, internuclear bridging, nuclear fragments, multinuclearity of late normoblasts, in addition to megaloblastoid change in the normoblasts and increased mitosis in granulocytic series. No chromosomal abnormality was found. Classified as RA after FAB classification of MDS. Showed good response to conservative management for anemia for more than one year.

This study was performed to investigate the possibility of acetaldehyde oxidation on Co/carbon black catalyst. The experiment was conducted at the reaction temperature of 200~440℃, the acetaldehyde concentration of 0.94mole% in air and the cobalt loading amounts of 2~60wt%. The characterization of the carbon black and Co/carbon black catalyst was carried out by TGA and XRD analysis. The thermal characteristics of the carbon black was stable to the high temperature(600℃). XRD result showed that Co/carbon black were destroyed and new metal oxide were formed such as Co_(3)O_(4). Co_(3)O_(4) crystallite addition on the catalysts surface provided the greatest enhancement of the catalytic activity. The order of activity on acetaldehyde oxidation was summarized as follow: SiO_(2)<TiO_(2)<carbon black<SiO_(2)-Al_(2)O_(3). It was found from the experimental results and the economic consideration that carbon black could effectively be utilized as a support for acetaldehyde oxidation. The activity of Co/carbon black catalyst were varied with the cobalt loading amount and the optimum loading content of cobalt was found 10wt%.

Recently, a variety of stimuli including convulsion, ischemia and noxious stimuli have been shown to induce the expression of c-fos mRNA in central nervous system (CNS). In this study, c-fos expression in both mRNA and protein (Fos) levels is examined up to 72 hr in brain regions, including hippocampus, piriform cortex, neostriatum, amygdala, dentate gyrus, cerebral cortex, and thalamus during lidocaine-inducced convulsion. Intraperitoneal administration of lidocaine (120 mg/kg) induces generalized convulsion of rats within 10 min and subsequent increase of c-fos expression in both mRNA and Fos protein levels in dentate gyrus, piriform cortex, amygdala, neostriatum, cerebral cortex, hippocampus, and thalamus. A prominent induction of c-fos mRNA and Fos protein in dentate gyrus suggests that dentate gyrus plays an important role in the process of lidocaine-induced convulsion. These results suggest that c-fos may participate in plastic changes of central nervous system associated with stimuli such as seizure activity.

LEISURE 로서의 自由學藝敎育에 관한 考察

김성룡,김형준 群山大學校 1995 論文集 Vol.22 No.-

It is said that the identity of American and Europian culture is based on the Ancient Greeks. In Ancient Greeks, the liberal arts were valued highly as the most important and the basic way to make human value, the existence of human beings and the universal values noble and honorable, which were the basis of the indivisual's happiness, the stability of democracy and the democratic society. That's way where the American and the Europian society face to the politician, social and humanistic crisis, they tend to come to life again the spirit of Ancient Greeks culture. The aim of this paper is to think about the relationships of leisure and liberal arts, referring to the work of M. J. Alder, who has seek the policy of the learning society and the way of liberal arts education in USA.

오형식,성정섭 木浦大學校基礎科學硏究所 1985 基礎科學硏究誌 Vol.3 No.-

TiO₂/water suspension에 UV광을 조사하여 생성되는 H₂와 H₂O₂를 연구했다. H₂와 H₂O₂의 생성속도는 GC와 요오드 적정법으로 측정했다. 여기서는 반도체의 양을 세가지로 나누어 실험한 결과 H₂의 극한속도는 조사시간이 약 2시간일때 였고 H₂O₂의 극한농도는 3시간 이후 일때 였으며 시간이 증가 할 수록 점차로 O 에 접근함을 알 수 있었다. H₂와 H₂O₂의 생성에 대한 양자효율은 각각??과 ??이었다. Photosynthetic generation of H₂and H₂O₂is demonstrated on UV-irradiated TiO₂/water suspensions. The rate of H₂and H₂O₂generation were monitored by a combined analytical-gas chromatographic procedure as a function of irradiation time and solid content. The rate of H₂evolution of TiO₂for three levels of solid content in the reaction mixture. A limiting rate of H₂generation is attained after∼2h of illuminations. This limiting rate is directly proportional to the concentration of TiO₂. A limiting concentration of H₂O₂is attained after ∼3th of illumination, and concomitantly the rate drops gradually to zero. The apparent quantum yields for generation of H₂and H₂O₂on TiO₂were calculated to be ?? and ??, respectively.

흰쥐 뇌의 선조체로부터 catecholamine, indoleamine 및 대사산물을 동시분석할 수 있는 간편한 방법을 제시하였다. 기기는 ECD를 장착한 HPCL를 사용하였고, 고정상인 C_18 컬럼에서, 이동상은 10mM citric acid, 0.13mM Na_4EDTA, 0.58mM SOS를 함유하는 35mM sodium acetate buffer(pH 3.4) : MeOH=85:15가 최적이었다. 이 때 컬럼온도는 30℃였다. 이 조건으로 dopamine(DA), 3, 4 -dihydroxyphenyl acetic acid(DOPAC), homovanilic acid(HVA), 5-hydroxyindole acetic acid(5-HIAA), serotonin(5-HT) 및 noradrenaline(NA)을 미량까지 분석할 수 있었고, 검출한계는 각 성분에 대해 1회 주입당 2~10pg이었다. 이 방법으로 흰쥐의 주령 및 성별에 따른 선조체내 생체아민과 대사산물의 함량을 비교하였다. 7주령 쥐에서 암컷은 수컷보다 DA와 5-HT의 함량이 유의성 있게 높은 것으로 나타났으며, 주령이 증가함에 따라 암컷에서 DOPAC의 함량이 유의적으로 증가하였다. A simple, efficient and sensitive method was described for the simultaneous determination of catecholamine, indoleamine and related metabolites from the homogenates of the rat brain striatum by HPLC-ECD. The optimum mobile phase on a reverse phase C_18 column was 35mM sodium acetate buffer(included 10mM citric acid, 0.13mM Na_4EDTA, 0.58mM SOS, pH 3·4):MeOH=85:15. The column temperature was 30℃. Dopamine(DA), 3, 4-dihydroxyphenyl acetic acid(DOPAC), homovanilic acid(HVA), 5-hydroxyindole acetic acid(5-HIAA), serotonin(5-HT) and noradrenaline(NA) could be separated and analysed to very small amount. The detection limits of this method were 2~10pg per injection for all components. The effects of age and sex of rat on the contents of the catecholamines and their metabolites in rat brain striatum were studied. The levels of DA and 5-HT contents of the 7 week old female rats were higher than those of the 7 week old male rats. As the age of rat increases, the contents of DOPAC increased significantly.
