韓國 理念敎育의 變遷過程과 方向 : 大學의 理念敎育을 中心으로 On the Ideology Education in the University

趙成大 상명대학교 논문집 1984 상명대학교논문집 Vol.13 No.-

1. The ideological strife and split which were caused by the division of the national land, the nation ideology in 1945 when our fatherland was liberated have been deepened since the Korean war lasted between 1950-1953. The prospect is that these thorny problems will be solved only by the unification of the fatherland. 2. The national situation and the viewpoint of the nation made the ideology education indispensable to us. That is the reason why it has been carried out since the liberation of this land. For Examples: The Citizenly education of the democracy since the liberation, the anti-communist education since the Korean war broken out on June 25, 1950, the national security education since the May 16 military coup, the ethic education for the nation under the rule of the yu-shin renovation political system and the critical education of ideology during the past decade of the I980. 3. The two kinds of problems follow the education of ideology today namely the outward problem of university campus and inward problem of the campus. The former problem is that the unsebect rush publication of books conlerning ideology by virture of the disbandment measures of the books forbidden publication during the past 35 years brought about profound confusion in the field of ideology education. Mean while, the latter problem is that contents, methods, assessment of ideology education are in the vague, and professors as well as students lack the understanding of ideology education. 4. For the present, ideology education limits to the criticism of communism. However, it is desirous to include criticism of ideology of our part as well. Because in view of education it will be more fruitful to compare ideology of the apposite side with that of ours. 5. Generally speaking, in the field of ideology education in the university, carrying out the national ethic education in wise harmony with the critical education of ideology will attain to such high level of perfection as wished. 6. In order to win north Korean puppet regime in war of ideology it is necessary for us to arm with stronger ideology not only to overcome ideological challenge but also to defeat it. Only the persistent and stead fast ideology education can get it. Fo us the way to win the commuist north Korean puppet regime which pursues cruel and threat-cutting ideology education policy is to have better structure of ideology education ourselves. 7. The Ideology Education aims at winning the communist planting faithfulness for the fatherland, the nation for younger generation, and giving them conviction on the righteousness, superiority of our political, social system. It also aims at providing them with vision of society, politics, nation history, of enjoying splendid life, exact understanding on present political situation, and convition in the prospect of the bright future and the will to fullfill them with patriotism as well. That is the reason why ideology education must be continued as long as the nation and country exist.

韓國 國民精神敎育의 現況과 改善方案에 관한 硏究

The national ehics education which is now teaching in school, has a lot of problems to be solved. They are misunderstanding and lack of recognition for it, lack of teachers and professors to teach it, insincerity and lack of support, and defects lying in the management, methods and contents etc... Therefore I think we should improve the national ethics education by means of emphasizing the necessities of it, and having excellent teachers and professors, and supporting of school managers(masters) and developing the books of good references, and changing the imperfections into perfections. In the unification security education, we have to educate people, not attaching importance to the South-North relations, but the contents which are able to have a better view of our security and unification under the international situation and relations, and we also have to set up a new synthetic learning place everywhere throughout the country, where we should help students be able to see, feel vividly the actual circumstances of North Korea and our serious unification problems. AT the same time, we should not only educate the students through on-the-spot study of Tunnel which was built by North-Korea and of a hard-fought field of the Korean War, but also we should educate students to have a firm consciousness for the unification and security, by means of holding discussion, seminar and a public hearing, and it is also necessary that we should go on amplifying of the unification-security education by using of mass medium-the improvement of new teaching material and instruments, TV, radio, newspaper and magazines, etc, ... In the national economic education, we should educate students the contents which are closely connected with everyday life of people and should educate them to have abilities to cope with changes of economical situation, and we can expert that our national economic education will be successful realization if we solve these problems above by strengthening of the economic education through everybody's participating and school education. In the New Community education, we should educate students with contents and methods which can act up to the consciousness level, the standard of living and desire of the people. On the other hand, we have also many difficult problems that we should keep to have excellent professors, to improve the educational facilities, and to develop the teaching materials and to make people recognize correctly the real meaning of the New Community education. At the same time, the New Community education should strengthen its basic meaning as a kind of social movement that all the people in our country take part in it with pleasure. To be frankly with you, it has depended on the governmental support and help this while, but now it should be one that is living and moving in the people by giving up its former self.

韓國의 國民精神敎育과 外國의 國民精神敎育

趙成大 상명대학교 교육문제연구소 1987 敎育硏究 Vol.8 No.-

I have come to a conclusion as fallowing from looking into the meaning of the civics education of Korea and that of other countries. 1. Every country in the world, in order to keep its own country's security and properity, is educating its own civics education which is suitable to its own natural, geographical circumstances, its own historical and cultural backgrounds, and its political and social situations. 2. Comparing the civics education of Korea with that of other countries, the civics education of has Korea a synthetical character and it also includes the political education, civic education and moral education of foreign countries. Korea is now education it synthetically-the subject of morality in primary and middle school, ethics in high school and college, the ideologyxriticism education, in university, and civics education in every circle of society, and even for the governmental officials. From these various education of Korea, we can find out that the civics education of Korea has more lager scope of it then that of other countries. But to make it more effective, more and more research and efforts and needed for it. 3. We can infer from spirit educations of foreign countries that the informal education being realized by informal groups-home, friends, church, mass-media and human-relations is more effective than it depends upon the formal education being done by school education. 4. In general every country in the world is civics now doing its national through school and social education more effectively in developed countries which has made political stability and economical progress than in underdeveloped countries. Because of lack of fullconfidence for their political system, the discord and friction caused by economical unbalance and because of being weak in communal society, underdeveloped countries are not educating it more effectively. 5. West Germany and the Republic of China, in general as divided countries like Korea, are now doing the communism criticizing education and the things which contain the warning of danger of communism, but America and Japan, undivided countries, don't emphasize on them. 6. The Soviet Union, a suzerain state of communism, has been educating the spirit education by using its own special method to cultivate communists themselves. They have been using the methods one is early-training method that is called Freud style, and the other is mechanical, passive method and a conditioned reflex method called Pavlor Skinner style, at the same time, they are educating their people by using the methods that follow the self-criticism, group-pressure, isolation way, and pratical acquisition(a method that follows the principle which consciousness can be changed in action or practive- "we can learn while we works and work while we learn.") After all, I think it is rather correct expression that the civics education of Soviet Union is not the education to cultivate man, but to make only a communistic person. 7. Whether the civics education of one country will succeed or not, it depends upon how many interests and efforts the country can be paid for it and how much governmental and financial support can be concentrate on it, and it also depend on the strong sense of duty and the earnest efforts of teachers who are in charge of the education itself, and at the same time it also depends on how much effort the standents pay for it and how they accept it. On the country, if we look slightly upon it and the persons who are in charge of it, and regard it as only a subject of policy, it is very hard to make success. It is not for any special political party or any political power and any individuals or group but it is for dominating the fate of a country and for the existence and prosperity of on nation. Therefore everyone who is in high social level as a leader and all the people should pay all attention to the national education with a lot of interests and should give full support to it.

황성연,김영만,조대희 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.4

바켓반죽의 저온숙성이 바켓의 품질에 미치는 영향을 조사하였다. 글루텐을 완전하게 발전시킨 반죽을 세등분하여 즉시 성형하여 구운 것과 1∼-1℃에서 각각 24, 48시간 저온숙성시키고 발효 및 저온숙성 중의 pH변화와 유기산 종류 및 그 함량을 분석하였다. 바켓 발효과정중 생성되는 유기산은 acetic acid가 가장 많았으며 다음은 lactic acid였으며 저온숙성 중 pH변화는 극히 적었다. 각각의 시료를 20℃에서 저장보관하면서 DSC를 사용하여 crumb의 enthalpy 변화로 바켓의 노화 정도를 측정한 결과 반죽의 저온숙성 기간의 차이는 제품의 노화에 영향을 거의 미치지 않았으며 종류별로 구워낸 바켓의 저장중에 enthalpy가 증가하여 노화도에 차이를 보였다. 한편 관능검사의 결과는 2시간 발효시킨 바켓의 외관이 가장 좋았다. 그러나 맛, 조직감, 향미 등은 24시간 저온숙성시킨 것이 다른 것에 비하여 높은 평점을 받았다. This study was conducted to investigate influences of cold aged dough on the quality of bagutte. After 2 hours fermenting, the dough was divided 2 parts and they were stored in the refrigirator adjusted 1∼-1℃. The cold aging time was 24, 48 hours respectively. After 2 hours fermentation, the dough's pH was 5.45 and 24, 48 hours cold aged dough were 4.99, 4.81. During cold aging, the difference of pH was not significant. The main organic acids in the baguette were lactic acid, acetic acid and malic acid. Among these organic acids, the acetic acid was the largest quantity regardlessly in different fermentation and the cold aging time. Right after baking, the enthalphy of all samples were almost same even though in different cold aging time, but during different storage periods they showed the difference of retrogradation by the increase of the enthalphy. 24 hours cold aging baguette had the best taste, aroma and texture in the bread's score sheet.

금속산화물들은 각종 산업재료로서 유용하며 더욱이 그것들의 결정형 나노입자를 경제적으로 제조하는 기술은 21세기 첨단산업에 매우 중요하다. 저자들은 前報에서 화학합성법에 의한 각종 금속산화물의 나노입자를 제조하는 표준공정법을 연구하여 보고하였다. 본 연구에서는 그 표준공정법을 이용하여, 가넷의 일종인 BiDy_(2)Fe_(5)O_(12) 결정 나노입자 분말을 제조하고 그것의 자성체로의 응용을 위해 제품특성을 조사하었다. 가네트 제조과정에 필요한 침전물은 제품설계에 의거 몰비로 계산된 Bi, Dy, Fe의 질산염들의 혼합수용액에 침전제로서 pH NH_(3)-NH_(4)CI 완충용액 일정량을 가하여 얻어졌다. 이렇게 제조된 침전은 열처리과정을 거처 BiDy_(2)Fe_(5)O_(12) 결정형 나노입자 분말로 만들어졌다. 얻어진 제품의 입자크기, 조성, 결정구조 및 광자기성 등 특성시험이 SEM, ICP, XRD, 그리고 VSM 등을 사용하여 실시되었다. 각종 분석법을 사용하여 제품의 특성을 조사한 결과, 최초에 설계한 대로의 자성체가 나노 크기의 분말로 얻어졌으며 이것을 통하여 전보에서 확립한 표준공정법의 유효성도 입증되었다. Metallic oxides are useful as various industrial materials. Futhermore, the cost-effective techniques of fabricating the crystalline nanopartides of metallic oxides are very important for the high-tech industries of the 21 century, In the previous study, the authors reported the standard process for the preparation of crystalline nanoparticles of metallic oxides by chemical synthesis, In this study, BiDyzFesOiz nanoparticles were prepared by using the reported standard process and the characteristics of the product were investigated for applicability as magnetic substance. The precipitation needed for manufacturing process of garnet was made by adding the NH_(3)-NH_(4)CI buffer solution of pH 10 to the mixed solution of bismuth (III) nitrate, dysprosium(III) nitrate and iron(III) nitrate. The amount of each nitrate was calculated by the designed mole ratios. The nano-size crystalline powders of BiDy_(2)Fe_(5)O_(12) were earned by heating the precipitation at 800℃ for 4 hours in air. The characterizations, such as particle size, composition, crystal structure and magneto-optical property of garnet were tested by SEM, ICP, XRD, and VSM analyses. The results of the analyses showed the following two facts. First, a good magnetic substance of BiDy_(2)Fe_(5)O_(12) was earned as crystalline nano-size powders according to the original design. Next, the established standard process for the fabrication of METALLIC oxides nanonartieles was approved as a very effective method.
