稀薄磁性合金에 있어서의 Spin 相關效果

太正學 梨花女子大學校 韓國生活科學硏究院 1983 韓國生活科學硏究院 論叢 Vol.31 No.-

Kondo 效果에 관하여 Takano와 Ogawa가 超傳導理論에 適用한 Gorkov의 方式을 利用하여 세운 運動方程式에 特別한 條件을 주면서 간단한 형식으로 변경함으로써 稀薄磁性物質과 傳導電子사이의 spin 相關函數를 計算하였다. 그리고 兩者間의 相關效果는 두 種類의 電子사이의 距離 γ이 γ≪γ_0(=vf/2Δ)일때 크고 γ≫γ_0일때 작아진다. The spin correlation function between a magnetic impurity in dilute alloys and conduction electron is investigated. Here, we use the Gorkov's equation which was applied to the theory of superconductivity and transformed it into a more simplifiel form under a certain special condition without changing essential property. The correlation effect is large when the distance between these two kinds of electrons γ is much smaller than γ_0 (=vf/2Δ) and it is small when the distance is larger thant γ_0 (=vf/2Δ).

低溫카륨의 電氣抵抗에 對한 Phonon 效果의 影響

太正學 梨花女子大學校 韓國生活科學硏究院 1977 韓國生活科學硏究院 論叢 Vol.19 No.-

電子에 영향을 주는 카륨 이온 全體에 의한 pseudopotential을 이용하여 電子-phonon의 相互作用을 一般的으로 計算하고 여기에 單一平面波 近似를 취하여 行列要素의 自乘形을 구했다. 電子와 phonon의 分布狀態의 可能한 여러 경우를 考察하여 Boltzman-Bloch 式에서의 衝突項을 計算하고 電場이 附加되지 않았을 때와 附加되었을 때의 電子와 phonon에 관한 方程式을 수립하였다. Phonon drag를 고려하여 試行函數 ^→k·^→u 에 비례하는 그 비례상수를 溫度의 函數로 前提하여 表現하였다. 이렇게 해서 決定된 試行函數를 Ziman의 變分法에 의한 電氣抵抗의 式에 代入하여 計算을 實施하였다. 그 결과 2˚~20˚K의 溫度 範圍內에서 Ekin과 Maxfield의 實驗과 비교해 볼 때 phonon drag 효과는 Kaveh와 Wiser의 결과와는 달리 그다지 重要하지 않다는 결론을 얻었다. 이에 대한 該細한 檢討를 하였다. A whole process of calculations is presented for the temperature dependuce of the electrical resistivity of potassium at temperature range(2˚~ 20˚K). In calculating the collision term, we take the trial function proportional to ^→k·^→u and the rate coefficient to be a function of temperature. Thus the phonon drag effect is considered. Comparing with the results of Ekin and Maxfield’s experiment, we find that phonon drag effect is not so much important in contrast to Kaveh and Wiser.

Cds Single Crystals were prepared from luminescent grade powder by the vapor transport method using high purity Argon gas as carrier gas. The temperature of inner furnace was kept from 900°C to 1050°C and the flow rate of Ar gas within the range of 20cc/m in.∼85cc/m in. We maintained this state for 2,5hr∼10hr. The longer the time of growth, the more irreguler the crystalforms, so that thickness and diameters of individual crystals could not growth further. Nweedle, rod, and platelet crystals were obtained. The mixing ratio of Crystal forms mainly depend upon the temperature of growing and flowing part and flowing rate of Ar gas. According to Laue Method, the crystals grown were judged as hexagonal. Espeicially, we recognized that many branches of platelet were obtained at the crystal planes (12 10), and crystal planes (2130) were predominant at the first experiment.

太正學 梨花女子大學校 韓國生活科學硏究院 1984 韓國生活科學硏究院 論叢 Vol.34 No.-

觀測의 問題를 量子力學의 基礎가 되는 波動函數의 解釋과 結付시켜서 檢討하고 Ginzburg-Landau 理論에 根據하여 超傳導體 안에서의 秩序狀態를 위치에 의존하는 秩序 parameter와 量子力學에서의 波動函數와 連關시켰다. 超傳導體 狀態가 巨視的인 規模로 나타나는 Josephson 效果의 特性을 利用하여 cooper pair가 2개 超傳導體 사이의 位相差에 의하여 이동하는 것을 前提로 하여 對象系의 徵視現象과 觀測裝置하는 巨視現象간의 關係를 다리놓기 위한 基礎昨業을 檢討하였고 兩者간의 分離不可能性을 土臺로 量子力學에 固有한 一貫性 있는 관측이론을 追求하였다. A quantumn mechanical problem of measurements was examined by inter-preting the meaning of wave function, which is correlated to the order parameter. The parameter can be a applied to the theory of superconductivity in ordered states by Ginzburg-Landau. Josephson effects were proved to be a phenomenon of superconductivity in a large scale. It was attempted that two phenomenological regions, microscopic object system and macroscopic apparatus, are bridged by using the characteristic properties of the effects and movement of cooper pair due to phase difference between two pieces of superconductive metals. The author pursued to construct the proper and consistent theory of measurement in quantum mechanics on the basis of inseparability of regions.

圓筒形 Fermi 面에서 Galvano 磁氣敎果에 關한 理論的 硏究

太正學 梨花女子大學校 韓國生活科學硏究院 1971 韓國生活科學硏究院 論叢 Vol.6 No.-

In order to understand theortically in a better way the striking experimental behavior of the galvanomagnetin effect common to most of metals, a study is presnted for a model of circularly cylindrical fermi-surface on the basis of the SchocKley-Chambers tube iutegral of electrical conductivity tensor. Two kinds of orits,ie closed and open orbits are possible for this model. The concrete function-forms of the magnetoresistance tensor are found for both low and high magneric fields,and also both closed and open orbits. The behavior of the fiuntions is quite to those experimentally observed in most of metals.

大學의 硏究機能

太正學 梨花女子大學校 韓國生活科學硏究院 1980 韓國生活科學硏究院 論叢 Vol.26 No.-

本 論文은 世界 特히 西獨, 英國, 美國, 日本의 여러 大學의 硏究機能을 比較 檢討하였다. 그래서 硏究機能이 大學에서 그 正常的인 活動을 하려고 하면 어떻게 하여야 하는 것을 考察하였다. 大學의 硏究機能은 다음의 세 가지 1) 學究的 硏究 2) 敎育을 위한 硏究 3) 技術開發이나 市民生活의 改善에 應用하기 위한 硏究로 分類된다. 硏究의 類型이 어떤 것이든 간에, 硏究 機能은 大學의 다른 機能과 密接不可離한 관계를 가지고 있고 서로 活性化시키는 데 중요한 役割을 하고 있다. 大學이 存續하는 限 硏究는 그 核心이고 따라서 不可避한 일이다. The author has compared the resarch function of universities around world, especially in Germany, England, America and Japan. In doing so, the author discussed how the normal research function should be realized. He also classified the types of research function into three according to their purposes, 1) academic research 2) research for education 3) research for application both to technology and citizen life. No matter how the types of research may be, research function activates the other part of university function. Reseach, therefore, is a core and inevitable matter at universities so long as it continues to act and to be alive.

This is a brief study for getting suggestions of the functional roles of woman university students in rural community development in Korea. For this purpose, the study activities carried out with two major methodological channels; one was the survey type including questionnaire, interview and documental analysis and the other was experimental service activities by professors and students of Ewha Womans University. The experimental service activities were executed three times from 1968 to 1969 at about 20 villages of Kangwon and Kyungi provinces. And expecially, this study carried out from the following five aspects; (1) mental (2) sociocultural ()3) educational (4) food and nutrition (5) health and medical. The major findings and suggestions for the role which students have to mention and act in practice in helping the rural community development are as follows: 1. Mental and philosophical aspect (1) Woman students have to try to get real report with deep understanding and enrich their mind through dialogue, communication, dramatic play with rural dwellers, reading newspaper, etc. (2) To make them keep their own good tradition (3) to make them have new and higher religious and ethical attitudes. 2. Socio-cultural aspect (1) Rural dwellers have been influenced very much by urban residents, and so it is very difficult to make them follow students teaching and direction. (2) Therefore, students have to try to discuss, eat, live, play and work with them in the same living conditions and standards in rural area. 3. Educational aspect (1) Students are also students, and so they have limit in time and work in helping rural dwellers. (2) Rural parents are very eager to educate their children at much better ad higher level of schools. However, their short economic conditions could not satisfy their own desire. (3) And so students must emphasize childrens care, teaching and hygiene. (4) Rural parents have, sometimes, irrational thinking and attitude and so they have to be enlightened to have more rational thinking and attitude. And at the same time, they must be directed to self-helping philosophy and attitude. 4. Food and nutrition aspect (1) The pork, chicken and cuttle fish were (shown as inclined to show) the most preferable meats. On the other and organ meats such as liver and intestines showed unexpectedly less desirable to include in their meal. On their reflection to other meats, they hope not only take them at the annual festival days but at other occasions, which area few probably once or twice a year, to get the meats. (2) Intake of carbohydrate was too high and that of fat too low in the diet. This fact caused the unbalanced condition of caloric intake. The level of calcium, vitamin A and vitamin B₂intake revealed subnormal condition in comparison to the recommended dietary allowances. The good quality of protein intake from the animal sources was the weakest part in the diet. 5. Health and Medical aspect, (1) Rural people had 1,756 symptoms per 1,000 population during the 1 year period, averaging 1.8 symptoms. Male 1.3 symptoms per capita a year and female 2.3 symptoms. The highest incident occurred among 45-64 age group, 3.5 symptoms per capita a year. (2) The main symptoms are 40 and their incidence rate is very high. (3) Only 20% of their symptoms did rural people regard as being illness, so 633 cases required medical are among 1,000 population.

鄭重鉉,尹玄佑,姜鉉植,太正學 연세대학교 대학원 1976 延世論叢 Vol.13 No.2

The nature of the green euminescence center in N-ion implanted ZnSe has been investigated. The N-ion were implanted with energy of 60 keV at dose of 1015 ions/cm2. The photoluminescence excited by UV lamp always exhibits edge emission, intense green and weak red at 77˚k, peaked at 4630Å (2.68 eV), 5300Å (2.34 eV) and 6300Å (1.98 eV), respectively, The edge emission and green band completely quenched out at above 210˚K, but the red band did not. By observing the temperature dependence of the peak energy shift and the variation of the half-width of the photoluminescence spectra the green center can be assumed to be the localized one and the transition type classified into Scho‥n-Klasen's model. The activation energy estimated from the above measurement was 0.11 eV.
