수중 Plasma 공정을 이용한 Ralstonia Solanacearum 불활성화
백상은 ( Sang Eun Back ),김동석 ( Dong Seog Kim ),박영식 ( Young Seek Park ) 한국환경과학회 2012 한국환경과학회지 Vol.21 No.7
A dielectric barrier discharge (DBD) plasma reactor was investigated for the inactivation of Ralstonia Solanacearum which causes bacterial wilt in aquiculture. The DBD plasma reactor of this study was divided into power supply unit, gas supply unit and plasma reactor. The plasma reactor consisted of a quartz dielectric tube, discharge electrode (inner) and ground electrode (outer). The experimental results showed that the optimum 1st voltage, 2nd voltage, air flow rate and pH were for 100 V (1st voltage), 15 kV (2nd voltage), 4 L/min, and pH 3, respectively. At a low 1st voltage, shoulder and tailing off phenomena was observed. The shoulder phenomenon was decreased as the increase of 1st voltage. R. Solanacearum disinfection in the lower air flow rate was showed shoulder and tailing off phenomenon because the active species generated less. Under optimum condition, shoulder and tailing off phenomenon was reduced. When the 2nd voltage was less than 7.5 kV, tailing off phenomenon was observed and this was not vanishes even though the increase of the disinfection time. The inactivation efficiency increased as the increase of air flow rate, however, the efficiency decreased when the air flow rate was above 4 L/min. R. Solanacearum disinfection at pH 3 showed somewhat higher than in pH 11. The pH effect of R. Solanacearum deactivation is less than the impact on other factor.

Up to now, after I had examined the relation between the origin of Fung(風) and Gi(氣) and the mean of Fung in medical science, I obtained the conclusion being as follows. The first, Fung(風) means a flux of Gi(氣) and Gi shows the process by virtue of the form of Fung, namely, Fung means motion of Gi. In order words, it is flow of power. Accordingly, the process of all power can give a name Fung. The second, Samul(事物) ceaselessly interchange with the external world to sustain the existence and life of themselves. And they make a adequate confrontation against the pressure of the outside. This the motive power of life action(生命活動) is Gi and shows its the process on the strength of Fung. The third, Samul(事物) incessantly releases power which it has to the outside. Power released to the outside forms the territory of the established power in the environment of them and keep up their substance(實體) in the space time(時空). It can be name Fung because the field(場) of this power incessantly flows. The fourth, man operates life on the ground of the creation of his own vigor(生氣) for himself as the life body(生命體) of the independence and self-support. The occurrence of this vigor and the adjustment process(調節作用) is supervised by Gan(肝). That is to say, Gan plays a role to regulate and manage the process of Fung or the action of vigor with Fung-Zang(風臟). The fifth, because the Gi-Gi adjustment process(氣機調節作用) of Gan is the same as the process of Fung, Fung that operates the cause of a disease is attributed to the disharmony of the process of the human body Gi-Gi. Therefore, the generating pathological change is attributed to the extraordinary of the function by the incongruity of Gi-Gi(氣機) or the disorder of the direct motion of Gi-Hyul(氣血). Because the incongruity of this Gi-Gi of the human body gives rise to the abnormal fo Zung-Gi(正氣) in the human body properly cannot cope with the invasiong of 'Oi-Sa(外邪). Furthermore, Fung serves as the mediation body of the invasion of other Sa-Gi(邪氣) because of its dynamics. By virtue of this reason, Fung is named the head of all disease. And because the incongruity of the Gi-Gi has each other form according to Zang-Bu(臟腑), Kyung-Lak(經絡), and a region, the symptoms of a disease appear differently in line with them as well. The sixth, Fung-byung(風病) is approximately separted Zung-Fung(中風) and Fung-byung(狹義의 風病). Zung-fung and Fung-byung is to be attributed to the major invasion of each Jung-gi and Fung-sa(正氣와 風邪). But these two kinds stir up the problem to the direct motion of Gi-hyul(氣血) and the harmony of Gi-Gi in the human body. When one cures it, therefore, Zung-fung has to rectify Gi-Gi and the circulation of Gi-hyul on the basis of the supplement of Jung-gi(正氣) and Fung-byung must make the harmony of Gi-Gi with the Gu-fung(驅風). -Go-gi(調氣), Sun-Gi(順氣), Hang-Gi(行氣) - All existing living things as well as man maintain life on the ground of the pertinent harmony between the soul(精神) and the body(肉體). As soon as the harmony falls down, simultaneously life disappears as well. And Fung which means the outside process between Gi(氣) and Gi(氣) makes the action of their life cooperative and unified. Accordingy, the understanding of Fung, first, has to start with the whole thought that not only all Samul(事物) but also the soul and the body are one.
통합유치원 장애 유아의 또래 관계 변화와 또래 관계 유능성과 장애 유아 수용도가 또래 관계에 미치는 영향

본 연구는 약 5개월간 3차례에 걸쳐 통합유치원 재원 중인 특수교육대상 유아들의 또래 관계 변화를 또래 지명법과 사회연결망 분석 통해 알아보았다. 또한, 또래 관계 유능성과 장애 유아 수용도이 또래 관계에 영향을 미치는지를 알아보았다. 통합거점 유치원 5곳의 만4세, 5세 학급 각 2학급씩 총 10학급의 19명의 특수교육대상 유아와 241명의 통합학급 유아들을 대상으로 연구를 진행하였다. 연구결과, 특수교육대상 유아들의 또래 관계는 독립된 소그룹형태의 제한된 형태가 지속되고 있었고 이들의 또래 관계는 시간이 지나도 통계적으로 유의미한 변화가 없었다. 한편 유아들의 또래 관계 유능성과 장애 수용도는 또래 관계를 나타내는 연결중앙성과 유의미한 상관관계를 보였고 유의미한 영향력을 나타냈다. 특수교육대상 유아를 놀이에 초대한 통합반 유아들과 이들을 초대하지 않겠다고 지명한 통합반 유아들의 장애수용도 전체 및 그 하위 범주인 장애 유아와의 상호작용 의도가 유의미하게 높았다. 본 연구의 시사점 및 제한점과 후속 연구에 대한 제안을 논의하였다.
