승화방법으로 광전도체의 CdS 단결정을 성장하였고 외삽법으로 구한 a_o와 c_o 의 격자상수 값은 각각 4.1318Å과 6.7122Å임을 알았다. Hall 측정값으로 부터 상온에서의 CdS 단결정의 운반자 농도와 이동도는 각각∼10^23m^-3과 2.93×10 exp (-2)㎡/V sec 이였으며 온도에 따른 이동도 변화는 33 K에서 150 K까지는 T^1/2 에 따라 증가하는 경향이 있고 180 K 에서 상온까지는 T^-2에 따라 감소한 경향이 나타났다. 광전류 측정으로 부터 나타난 단파장대의 봉우리는 진성전이에 기인하는 봉우리였으며 이 봉우리의 에너지값은 CdS 광전도체에 에너지 밴드 갭과 동일한 값을 나타냄을 알았다. A CdS single crystal was grown by using sublimation method. Lattice constants, a_o and c_o , obtained by using extrapolation were 4.1318 Å and 6.7122 Å, respectively. The carrier density was∼10^23m^-3 and the mobility was 2.93×10 exp (-2)㎡/V-sec from measured Hall data at room temperature. The mobility has a increasing tendency in proportion to T^1/2 from 33 K to 150 K and a decreasing tendency in proportion to T^-2 from 180 K to room temperature. The short wavelength band peak measured from photocurrent was due to intrinsic transition, and the energy value of this peak was equal to the energy band gap of CdS photoconductor.

眉叟許穆의 경북지역 篆書懸板연구

정태수 동방문화대학원대학교 문화와예술연구 2015 문화와예술연구 Vol.5 No.-

허목許穆(1595(선조 28)∼1682(숙종 8)은 본관이 양천陽川, 자는 문보文甫·화보和甫등이고, 호는 미수眉叟〮.태령노인台嶺老人이 다. 허목은 당시 보기 드문 개성적인 자가풍의 전서를 활용해 많은 작품을 남김으로써 후인들이 그의 이런 전서를 두고 ‘미 전眉篆’이라고 칭하였으며, 전서로는 ‘동방제일’이라는 평가를 얻었다. 그의 학문은 고학古學이고, 문장은 고문古文이며, 서예 는 고서古書라고 할 수 있다. 허목은 삼대치도三代治道의 이상향을 미전眉篆으로 표현하였 고, 삼대三代를 동경하며 그 때와 같은 태평성대가 실현되기를 기대하였다. 특히 자신이 만든 미전眉篆을 고집한 이유도 여기 에 있었다. 그러나 당색에 따라 그의 전서를 위전僞篆으로 폄 하하기도 하고, 가치를 높이 평가하기도 하였다. 특히 경북지역 에 산재되어 있는 허목의 전서현판은 빼어난 조형성과 역사성 을 지니고 있음에도 불구하고 서예사적으로 제대로 평가받지 못하고 있는 실정이고 지금까지 상세히 연구된 적이 없었다. 따라서 이 논문에서는 경상북도에 산재되어 있는 허목의 미전 으로 걸린 현판을 살펴봄으로써 한국서예사 자료보강에 일조하 고 ‘미전眉篆’의 예술적 가치를 되짚어 보는데 의미를 두었다. 허목의 경북지역 전서를 다루기에 앞서 우선 허목의 생애와 학 통을 검토하였다. 왜냐하면 삶과 학통은 한 사람의 학문성향과 예술환경을 좌우하기 때문이다. 그 결과 한강 정구와 퇴계에 이르는 학통에 따라 경북지역 성리학자들과 교류가 있었고, 그 들의 서원이나 별당 혹은 사랑채에 허목의 미전이 걸리게 되었 다는 것을 밝혀내었다. 아울러 당색에 따라 호불호가 나뉘었던 17세기 시대환경에 따라 동색同色의 선비들의 거소居所에 다수 의 미전이 걸렸다는 것도 파악할 수 있었다. 이를 통해 경북지 역 명가들의 서원, 사랑채, 별당에 걸린 허목의 전서현판의 내 용과 예술적 격조를 살펴봄으로써 그 동안 가려졌던 그의 예술 적 위상을 가늠해 볼 수 있었다. 봉화의 충재 권벌의 별당에 걸린 <청암수석>현판은 미수의 절필작絶筆作으로 밝혀졌고, 미전의 최종예술성을 지닌 작품으 로 천진한 품격을 보여주어 주목되었다. 영천의 완귀 안증의 정자인 완귀정에 걸린 <완귀정>현판은 주변의 정경과 어울리 게 문자의 편방을 재구성하였고, 각 문자에 맞으면서 전체 장 법을 고려한 예술성을 지니고 있다. 안동 하회마을 서애 류성 룡의 종택에 걸린 <충효당>현판은 이 건물의 당호이며, 서애 의 유시遺詩[후세에 전하다]에서 강조한 충忠자와 효孝자를 넣 어서 만든 현판이다. 충과 효를 강조한 내용을 살리면서도 경 직되지 않고 변화를 모색한 필획미를 느낄 수 있다, 성주의 회 연서원은 미수의 스승을 기리기 위해 지어진 건물이다. 스승을 대하듯이 운필에서 멋과 변화를 줄여 절제되고 정제된 분위기 를 드러낸다. <옥설헌>현판의 옥[귀하게 여김]玉자에 좌우로 길게 드리워진 대칭획이 일품이며, 장법에 있어서도 안정과 대 칭을 중시한 점이 살펴진다. 이와 같이 미전眉篆이 유독 많이 남아있는 경북지역 허목의 전서현판을 통해 한국서예사의 자료발굴에 일조하고, 미전眉篆 의 예술성에 대해서도 접근해 보았다. 아울러 자신만의 독특한 작품을 통해 한국서예의 새로운 면모를 개척한 허목에 대한 재 평가와 후속연구가 이어져야 할 것으로 사료된다. Heomok (1595 (Seonjo 28) ~1682 (Sukjong 8)) had a family clan name Yangcheon, eponyms such as Munbo and Hwabo , and pen name Misu, Elderly Taeryong and others. Heomok left a number of works that were singularly individual and Jaga-style utilizing seal script (one of ancient Chinese script style, Geonseo) to be later called ‘Migeon’, and got a rating of “the best in the east”. His area of the study was Gohak (A kind of primitive Confusianism), and his sentence was Gomun (prose style Chinese character), and his calligraphy can be said to be Goseo. Heomok represented a utopia of Samdai Chidori (ways of governing for three generations), and was expecting a reign of peace would be realized with a yearning for such three generations. In particular, this was the very reason that he was sticking to Migeon (signboard of Heomok) he himself made. However, according to the political party trend of his time, his seal script was either disparaged as a fake or praised highly. Especially, despite Heomok’s compendium signboards, that were scattered throughout in Gyeongsangbuk-do region, have superb formativeness and historicity, the present situation is that his work has not been evaluated properly in the history of calligraphy until now and has never been studied in detail. Therefore, this paper tried to find a meaning in contributing to reinforcing data on Korean history of calligraphy, and in revisiting the artistic value of Migeon by investigating the signboards hanging as Migeons of Heomok scattered in Gyeongsangbuk-do. Prior to dealing with seal script of Heomok in Gyeongsangbuk-do, this paper first examined his life and his scholastic mantle as life and scholastic mantle govern the academic propensity and the environment of arts. As a result, this paper revealed that there was interaction with scholars in Gyeongsnagbuk-do Confucianism party in accordance with a scholastic mantle from Hangang Jeonggu to Toegye, and the Migeons of Heomok were hanging in their Seowon (Confucius memorial hall), annex, or a detached house. In addition, it was revealed that a number of Migeon was hanging from the residences of scholars of the same color in accordance with the 17th century environment that was divided into the likes and dislikes depending on the colors of the parties. Through these, this paper could grasp his artistic status that had been overshadowed by looking at the content and artistic tones of Heomok’s compendium signboards hanging in Seowon, annex, or a detached house. <Cheongamsuseok> signboard hung in the annex of Chungjai Gwonbeol of Bonghwa turned out to be his last work, and was noted as a work with his final artistry showing innocent character. <Wangwijeong> signboard hanging in the pavillion of Wangwi Anjeung’s pavillion in Yeongcheon reconstructed its character’s radicals to go well with the surrounding scenery, and has the artistry fitting each character with the consideration on the overall calligraphic method (Jangbeop) in mind. <Chunghyodang> signboard in Seoae Seongryong Ryu’s Head House in Andong Hahoe Village is a byname of this building and is a signboard made of fidelity and filial piety that were stressed in Seoae’s poems for the future generations (Yusi). While highlighting fidelity and filial piety, it made one feel the beauty of calligraphy that was not rigid seeking changes. Hoeyeon Seowon is a building built to honor a teacher of Misu. It revealed the abstinence from smartness and changes in calligraphy stroke to reveal the reduced and refined atmosphere as if to meet a great mentor. A caligraphy of a character ‘Ok’ (玉) drawn long in <Okseolheon> signboard showed peerless symmetrical strokes fringed long with an emphasis on stability and symmetry in calligraphic method. Like this, this paper contributed to the data excavation of Korean calligraphic history through compendium signboard of Heomok that are especially found in abundance only in Geongsangbuk-do, and approached the artistry of Migeon. In addition, it is considered that the revaluation and subsequent research on new aspects of Heomok who pioneered new aspect of calligraphy through his own characteristic work should be followed.

Bandgap Modulation of BeZnO Layers Grown by using Hybrid Plasma-Assisted Molecular-Beam Epitaxy/Electron-Beam Deposition

정태수,김정현,D. S. Park,J. H. Yu,김택성,윤창주,홍광준 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.6

Alloyed BeZnO layers were grown by using hybrid plasma-assisted molecular-beam epitaxy/electron-beam deposition. From the X-ray measurements, we certified that the x composition of the BexZn1−xO layers increases with increasing temperature of the Be effusion cell. With increasing x, the optical bandgap energy ranges from 3.236 to 4.122 eV, and a large bowing parameter of 6.32 eV is measured. Therefore, this finding may open up new possibilities for wide bandgap materials by conducting bandgap engineering using bandgap bowing. This indicates that the BexZn1−xO layer through bandgap tuning can be utilized as a barrier layer in active layers consisting of the ZnO/ BexZn1−xO quantum well structure.

Impeller의 類型이 高粘度 液體의 混合에 미치는 影響

鄭泰秀,尹雲榮 成均館大學校 1982 論文集 Vol.32 No.-

Effectiveness of six types of rotating agitator in the batch mixing of high viscous liquid was studied in a vessel of 125mm diameter by measuring power input, mixing time and energy which is the product of power input and mixng time. The mixing time was measured by electrical conductivity of sodium chloride solution which was added as a tracer. The six types of agitators used were a four-blade paddle, a four-layer two-blade paddle, a six-blade turbine, a helical screw, a helical ribbon and an anchor agitator. The results are as follows: 1. For a helical ribbon, an anchor and a helical screw agitator, the mixing time was inversely proportional to stirrer speed and decreased in the order of a helical ribbon, an anchor and a helical screw agitator in the most range of rotational speed. 2. The power consumed for all agitators was proportional to the rotational speed and increased in the order of a helical ribbon, an anchor and a helical screw agitator in the most range of stirrer speed. 3. The anchor agitator consumed the least energy for stirrer speed in the range of 30-7-rpm, and beyond 70rpm the helical ribbon agitator consumed less energy than the anchor and helical screw agitators. 4. The two types of paddle agitators and the turbine agitator have been found not good enough to be used in the mixing of high viscous liquid in comparison with the other three impellers mentioned above.

The 500,000 Russian Koreans who have lived in the old U.S.S.R. are the desendants of Koreans moved from Priamurski around Vladivostok. Although their ancestors have lived for about 130 years under the old Soviet regime, being separated from their mother land, they created their own culture combining Korean's with Soviet's. After the Stalin's policy of 1937, The Mandatory Move of Russian Koreans, 200,000 of Russian Koreans in the Farthest east of Russia had to find new places separately in the western parts where they live now and became the minority of the ethinc groups. As the old Soviet was collapsed in 1980s, they formed new ethnic groups as Russian Korean, Uzebeckstan Korean, and Kazakstan Korean. I name them Russian Korean here. Related to Russian Koreans, the followings are examind in this paper : First, The use of the educational policies that Soviet employed for Russian Koreans after 1860s ; Second , the use of the educational policy that Japanese adopted from the old colonial days of Korea ; Third, the educational policy for the ethnic group after the Revolution of 1917 ; Fourth, the suggestion of the educational policy for Russianization VS the Right of the ethnic education in future.

國恥 直後의 新韓村과 韓民學校 硏究(1910~1914)

鄭泰秀 대진대학교 1993 大眞論叢 Vol.1 No.-

In the history of Korean independence movement from Japanese rule, the five years from 1910, when the Yi Dynasty fell by the invasion of Japanese Army, to 1914, the year shortly before the end of the First World War, had been a first transition period from the struggle of righteous army to that of independence movement. During the five years, Vladivostok, a Russian port located in the Far East, formed a base for the movement. Some Koreans established a residential quarters, Shinhan Village, there, and organized an assembly called "Shinhan Village Association" and a corps of independence movement called "Kwonuphoe". These organizations established "Hanmin School", which inspired the spirt of the independence movement. This paper aims, firstly, to survey the processes of deportation of Koreans in Vladivostok from "Kaechukni" to a new residence which Russian government provided. Secondly, we look at the procession of organization of Shinhan Village Association, the first assembly of the migrants, and the regulations of the board and its decision. Then we consider the organization of "Kwonuphoe", its board, regulations and activities. Lastly, we examine the first newspapers and cultural activities in Shinhan Village. Most of the paper is dedicated to the background of Hanmin School as an educational institution for Korean immigrants to teach their children their native language, history and culture. It will be considered with regard to the Russian policy of Russianizing Korean on the one hand, and fervent national education on the other. We describe in detail the leading founders of Hanmin School, the managerial states of the School and its curriculum. In an appendix, nine pieces of "chang-ga (vocal music)" such as the national anthem and "Keongukka (the national foundation song)" are recorded which were taught at School to inspire the spirit of national independence. In addition, the list of 501 anti-Japan Koreans in the Russian territory of the Far East and their activities are printed, which Japanese spies of the consulate general at Vladivostok collected to report in February, 1911.

열처리한 ZnSe 박막의 defect 연구

정태수,유평렬,최용대,이기선,오병성,윤만영,윤창주 한국물리학회 2002 새물리 Vol.44 No.1

The defects of ZnSe/GaAs epilayers treated in vacuum and in Zn, and Seatmospheres, and grown by using hot wall epitaxy were investigated by means of photoluminescence measurements at 10 K. The dominant peaks at 2.7988 eV and 2.7937 eV obtained from the photoluminescence spectrum of the as-grown ZnSe epilayer were found to be consistent, respectirely with the upper and the lower polariton peaks of the exciton, I$_2$ (D$^\circ$, X), bounded to the neutral donor associated with the Sevacancy. The exciton peak, I$_1^d$, at 2.7812 eV was confirmed to be bound to the neutral acceptor corresponding to the Znvacancy. This acceptor-impurity binding energy was calculated to be 268 meV. The I$_1^d$ peak was dominantly observed in the ZnSe/GaAs:Se epilayer treated in the Seatmosphere. This Se-atmosphere treatment is thought to convert the ZnSe/GaAs:Se epilayer into a p-type and the SA peak was found to be related to complex defects such as (V$_{Se}$-V$_{Zn}$)-V$_{Zn}$. HWE 방법으로 성장된 ZnSe/GaAs 박막은 진공과 Zn, Se 분위기 등에서 열처리되었고 이들의 10 K에서의 광발광 측정을 통하여 막 성장된 ZnSe 박막에 대한 결함이 논의되었다. 막 성장된 ZnSe 박막의 광발광 측정으로부터 얻어진 2.7988 eV과 2.7937 eV에서 우세한 봉우리들은 각각 upper polariton I$_2^U$와 lower polariton I$_2^L$로 중성 주개 bound exciton I$_2$ (D$^\circ$,X)이며 그 기원은 V$_{Se}$로 연상된다. 또한 2.7812 eV에서 I$_1^d$의 exciton 봉우리는 V$_{Zn}$에 대응하는 중성 받개 bound exciton 발광으로 확인되었다. 중성 받개 bound exciton으로부터 얻어진 받개 불순물의 결합 에너지는 268 meV이였다. I$_1^d$ 봉우리는 Se 분위기 열처리를 한 ZnSe/GaAs:Se 박막에서 우세하게 관측되었는데 이것은 Se 분위기 열처리가 ZnSe/GaAs:Se 박막에서 p-형 반전이 일어나도록 한 것으로 여겨진다. 또한 SA 발광은 (V$_{Se}$-V$_{Zn}$)-V$_{Zn}$과 같은 복합적인 결함과 관련이 있음을 알았다.
