분무열분해를 이용한 경희토류 산화물 입자의 제조

강동준,김선수,이승호 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.2

희토류 금속 및 화합물들은 최근 산업이 발전함에 따라 전기, 전자, 촉매광학, 연마제, 영구자석, 특수합금 및 형광체 등의 첨단소재로서 다양한 용도로 수요가 급증하고 있으며, 첨단산업의 발달에 따라 희토류 관련 소재화 연구도 활발해 지고 있으며, 그 동안 불모지나 다름없었던 희토류금속의 제조와 고순도화 기술개발에 대한 필요성도 점차 증대하고 있다. 희토류를 원소군 별로 분류하면 크게 경희토류 와 중희토류로 분류하는데 이 중에서도 경희토류를 대표하는 산화세륨은 광학용 유리, 촉매, 연마제, 유리용 첨가제 등으로 다양하게 이용되어 지며, 국내에서는 산업의 발전과 더불어 TV 브라운관, 고급 판유리, 렌즈 등 광학부품의 생산이 늘고 있어 이에 필수적인 고급 연마제의 국내수요 또한 증가일로에 있다. 분무열분해 또는 aerosol-toparticle conversion 기술은 주로 다양한 산화물 또는 금속입자 들의 제조에 이용되었다. 제조된 입자들은 일반적으로 micron 또는 submicron 크기에 상대적으로 좁은 입도분포를 가지는 구형입자들이나, 종종 중공입자 또는 다공성입자들을 얻는데, 이는 높은 반응속도 조건하에서 solvent의 증발이 지연되기 때문이다. 게다가 제조된 입자는 반응의 복합성 때문에 언제나 좁은 분포를 가지지 않는다. 따라서 제조된 입자의 특성을 조절하는 것이 이 연구에서 주된 관심사이다. 본 연구에서는 산화세륨 입자를 여러 변수(전구체 농도, 반응온도, 염 종류, carrier gas) 에 따라 분무 열분해법으로 제조해 보았다.

近代 韓國私學의 起源과 그 發展方向에 關한 硏究 : 政治文化的 側面을 中心으로

康東俊 건국대학교 1979 論文集 Vol.9 No.1

This study has relations with the history of the Yi dynasty, and of the modern education in Korea. But, it is neither the history of the Yi dynasty itself nor the history of the modern education in Korea. This study makes use the present results of the above·mentioned two disciplines, tries, to find out the aspect of political culture of the modern private schools, in terms of it's initial stage. In the first place, we understand the ertablishment of modern private schools in Korea, as the fourth attempt for the modernization of the Old Korea, The first attempt, before the open door policy of Korea, was taken by the progressive doctrinal movement within the framework of the confucian scholars based on the empiricism and pragmatism (the Sil-hak). The second, after the open door to the Japan, was the movement for the modernization of the Old Korea. The third attempt was the Revolt of Korean farmers (the Dong-hak) in 1894, before the war between China and Japan. Therefore, we consider the above-mentioned three movements as ideological background of the Korean modern private schools in terms of it's initial stage. In regard to the origins of the Korea modern private schools, Koreans have founded the schools, by their own fortunes, to fight in defense of their country, against the Japanese aggression by means of educating the people, whereas the mission schools have faunded by foreign missionary funds for the missionary works, based on the Christianism. In the meanwhile, the government of the Empire o Korea promulgated the Ordinance of the private schools in order to limit and control the private schools, while the students who learned the Japanese was increased, in the public schools, in great number. As for the development-orientation, reflected in the contents of teaching, the text books, the students' activities and, the popular songs for students, the major characteristics are as follows; First, such feeling as "I am the master of the country" is advocated intensively, but previously the king or the noble was the master, not the people; this is the radical change of idea. We find here a very sincere reflection of the relation between the individuals and the state. Second, the teachers and the students reproached openly the Japan for it's aggression and the government for it's powerlessness. Therefore, the Japaneses blamed the Korean private schools for being confused. the education with the politics and for the penetration of the "seditious idea" into the private schools. Hereafter, this anti-Japan orientation, changed in the anti-government orientation, became the resistance-orientation against the political power. Third, the establishment of the girls schools proved the break down of the traditional inequality of two sexes, the children of the noble and the common people learn together to approve the abolishment of the carte system. Moreover, the school for deaf and mute was founded. Here, we find the orientation for the equality among people. These political orientations, without a doubt, are found to be the efforts of criticing and overcoming the confucian tradition by which the Korean political tradition can be characterizel by it's authoritarian political culture, in which people were made subservient to the state through the requirement of loyalty. Certainly, the activities of the Korean modern private schools belong to the same category of the efforts put out by Sil-hak philosophy, Dong-hak philosophy, Modernization Movement and Independence Association Movement, and these efforts are considered to be the movements by the people to establish national identity and to promote equality within the society. In spite of the political and social visissitude, it is to be remembered that the originality of the aspect of the political culture, in the Korean modern private schools, consists in it's institutional continuity, that is, the continual development of the Korean private schools.

韓國私學의 그 政治性 : 民族運動을 中心으로 from the View Point of National Movement

康東俊 건국대학교 1979 論文集 Vol.10 No.1

This study is aimed at what the Korean private schools established at the end of nineteenth century accomplished about the Korean politics. From this study we find out as follows. (1) The establishment of the Korean private 7ch7ols was oriented from national crisis, and it was methods in order to resort these. (2) The Korean private schools have made education's purpose to inspire "patriotism" (3) "The save-the-nation movement of education" was "anti-Japan Movement" with passivity at an early stage. (4) In 1st March, 1919 there was the "Independence Movement" that was performed by the Korean private schools: chiefly the founders and students. (5) "The Korean Exciled Government" in China and the other independence bodies had comported founders and students graduating, of the Korean private schools. (6) "The Student Revolution" of Korea at 19th April, 1960 could achived the goals by the students of the Korean private schools. In conclusion the Korean private schools played the roll to lead the anti-Japan Movement, the National Sulvation Movement, the Demoracy Movement, and we shall consider to infuluence to Korean polities more than any others.

Relationship between Calcium/Inorganic Phosphorus and Parathyroid Hormone Concentrations in Dogs with Renal Failure

강동준,이수한,박희명,정병현 한국임상수의학회 2008 한국임상수의학회지 Vol.25 No.4

Parathyroid hormone (PTH) regulates calcium (Ca) and phosphate transport. Secondary hyperparathyroidism usually occur in chronic renal failure (CRF), and it is a common complication of CRF in dogs and cats. Twenty one dogs with renal failure were enrolled in this study. Plasma Ca, inorganic phosphorus (iP) and PTH concentrations were measured. Dogs were divided into two groups by the ratio of Ca to iP (Ca/iP≤1; Group I, Ca/iP≥1.5; Group II). The PTH level between sexes ages were not significantly different. The PTH level and Ca/iP between two groups were significantly different (p < 0.0001). In conclusion, The ratio of Ca to iP may be considered as useful surrogator to predict PTH level of dogs with renal failure.
