진공증착방법으로 제작한 Ni_53-Fe_47 박막에 관한 신형전류자기 기전력효과의 전류와 자장 방향이 만드는 각 θ 의존성이, 자기저항효과의 cos 2θ, Hall 1 효과의 경우 sin 2θ로 관측되고, 이 효과의 자장에 의존하는 전압변화율이 자기저항효과와 비교할 때 차수가 다르게 큰 것이 조사된다. 이 효과가 2 Carrier형 모델로 이해할 수 있음을 이론적으로 확인된다. A new Galvanomagnetic electromotive force effect of Ni_53-Fe_47 thin films is studied. The dependence of this effect on θ, angle between the current and the magnetic field, is found to be the form of sin 2θ, in contrast with that of the magnetoresistance effect cos 2θ and that of the Hall effect sin θ. Property of this effect is that the rate of the voltage variation depending on the magnetic field is extremely large as compared with the magnetiresistance effect. It is theoretically confirmed that this effect is well understood on the basis of the two carrier types model.

위장의 Helicobacter Pylori 감염에 따른 위 점막상피세포의 Nucleolar Organizer Regions : 장형의 위선암종과 비교

장태정,김동훈,배한익 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

1995년 3월부터 1995년 12월까지 동의의료원에서 위내시경 검사로 채취된 위 생검 조지절편에서 위염과 소화성 궤양 및 장형(intestinal type) 위선암종으로 진단된 증례 69예를 대상으로 Helicobacter Pylori(H. pylori)감염에 따른 세포증식능을 조사하고 장형 위선암종의 세포증식증과 비교하였다. 세포증식증은 은염색을 시행하여 AgNORs의수로 표시하였다. 이 중 위선암조은 16예, H. pylori감염 양성은 35예, 감염 음성은 18예 였다. H. pylori감염의 판정은 rapid urease 검사 ( CLO검사), hematoxylin-eosin염색 또는 Giemsa염색으로 하였고, H. pylori감염에 따른 염증반응은 H. pylori의 감염 양성군에서 중등도 이상의 중성구 침윤과 만성 염증세포의 침윤이 각각 82.9%(29/35),65.7%(23/35)였다.(P<0.05). 위 점막상피세포의 지저부 및 협부의 AgNORs갯수는 위선암종에서 4.01±0.50, H. pylori 감염 양성군에서 2.84±0.25, H. pylori의 감염 음성군에서 2.49±0.29 였다(P<0.05).H.pylori의 감염 양성군 및 음성군에서 중성구의 침윤에 따른 AgNORs갯수는 중성구의 침윤이 중등도이상인 경우가 2.80±0.24로써 중성구의 침윤이 없거나 미약한 경우(2.60±0.35) 보다 의의있게 높았지만(P<0.05) 만성염증세포의 침윤에 따른 AgNORs갯수는 유의한 차이가 없었다. 위염의 등급과 위염의 활동성 및 집락의 등급을 합친 위염점수가 높을수록 AgNORs갯수는 증가하는 경향을보였다(r=0.38, P<0.005). 그러므로 H. pylori의 감염이 있으면 위 점막에 염증반응이 생기고 이로 인하여 위 점막 상피세포의 세포증식능이 증가하는데 세포증식의 주 원인은 H. pylori자체일 수도 있고 H. pylori감염에 속발된 중성구 침윤일 수도 있다고 추측된다. The number of silver-staining nucleolar organizer regions(AgNORs) per nucleus has been correlated with proliferative rate and ploidy. The mean AgNOR counts of gastic mucosal epithelium in isthmus or base of nonmetaplastic area were examined in 18 Helicobacter pylori (H.pylori) negative cases, 35 H. pylori positive cases and 16 gastric adenocarcinoma of intestinal type. Acute and chronic inflammation of H. pylori positive cases were more serious than that of H.pylori negative cases(P<O.05). The mean number of AgNORs was 2.49±O.29 for H. pylori negative cases, 2.84±0.25 for H. pylori positive cases, and 4.01±0.50 for gastric adenocarcinoma. The difference among the groups was signiftcant(P<0.05). The mean number of AgNORs for those who showed moderate or severe infiltrate of neutrophil(2.80±0.24) was significantly different from that of patients with absent or mild infiltrate of neutrophi1(2.60±O.35)(P<O.O5). There was no difference of mean AgNORs counts according to chronic inflammatory cell infiltrate. A positive association between mean AgNORs counts and gastritis score was prescnt(r=0.38, P<O.OO5). The alteration of replication cycle of gastric mucosal epithelium may be caused by H. pylori infection or neutrophil.

문명의 발전과정에서 도시구조는 급격한 변화를 맞이하게 되었다. 그로 인해 자연공간이 손실되었고 이는 인간의 쾌적한 정주환경을 위협하는 요소로 대두되었다. 공원은 깨끗한 공기와 푸른 녹지의 중요성을 인식시키고 대도시의 시민에게 쾌적한 환경과 심신의 휴양공간을 제공하는 중요한 공공 녹지시설이다. 현재 도시에서의 공원은 수가 매우 부족하며 공원 본래의 개념을 간직하고 있는 곳이 드문 것이 현실이다. 본 연구에서는 급속한 산업화와 도시화의 과정으로 잠식되어진 도시의 녹지공간을 활성화시키기 위하여 도시공원의 실태를 분석·파악하고 문제점을 도출하여 이들 문제점을 개선하는데 그 목적이 있다. 따라서 도시속의 녹지공간과 친수공간의 중요성을 다시 한번 재검토한 후, 공원의 활성화를 통한 공원정비방안을 살펴보고 주변지역과의 연계를 통하여 도시와 자연이 어우러지는 도시환경정비방안을 제시하고자 한다. At development process of civilization, city structure met sudden change. Nature space lost thereby and this rose on constituent that threaten agreeable domiciliation environment of human being. The park is important public green area equipment that recognize the importance of clean air and blue green area and offer great environment and rest space of mind and body to metropolitan citizens. Scarce thing of place that the park in existing city is taking a little longevity and keep park original concept is actuality. To activate green area space of city that is encroached by process of fast industrialization and urbanization in this research actual conditions of city park analyze and grasp and is purposeful to improve these drawing problem. Recognize green area space of present city inside and the importance of receiving in person space again and search park full equipment way for park's activation and grope city and natural environment that nature gets put together through link with ambit.

Se/CS₂용액으로 처리한 n-GaAs 표면의 Photoreflectance 특성에 관한 연구

장광수,김인수,배인호,한병국,이정열 嶺南大學校 基礎科學硏究所 1997 基礎科學硏究 Vol.17 No.-

The surface of of n-GaAs(100) was treated using 1.5㎎/100ml solution of Se/CS₂. The passivation of the surface of this sample was investigated by photoreflectance(PR) experiment. After the surface treatment, the samples were annealed between 300 to 700 ℃ in a N₂atmosphere for 10 min. From the obtained Franz-Keldysh oscillations, we have evaluated the surface electric field(E?) and built-in voltage(V??). The density of surface states(Q??) and surface Fermi level(E??) of n-GaAs treated with CS₂and Se/CS₂solution were determined 1.78 ×10??㎝?? , 1.81×10?㎝? and 0.734 eV, 0.737 eV, respectively. After annealed at 600 ℃, These values were about 45% and 13% smaller than those in unannealed samples. It has found that the passivation of surface occured when the surface of the sample had been treated with Se/CS₂ solution and annealed from 400 to 600 ℃. This is ascribed to effects due to activation of elemental Se on the surface.

장지규,정한종 진주산업대학교 1992 論文集 Vol.31 No.-

The purpose of this study is to analysis the consequences of his Physical Education philosophy on Physical Education from the perspective of Dewey's Mind and Body-Monism. In conclusion, this study has examined his Physical Education Philisophy through Dewey's Mind and Body-Monism, though he did not refer directly to Physical education the importance of Schooling, and what is more, he did tile importance of Physical Education on Schooling. Besides, he emphasized that Man can make the healthy development of Body and Mind, through Physical Education of Mind and Body-Monism, and not only can help children whth Intellectual growth, but also cultivate the civic quality. Therefore, it is certain that Dewey's Physical Education Philosophy is very suggestive to Physical Education.
