미생물제제를 이용한 돈분뇨 처리시스템(3N-System, 속성발효시스템) 운영에 있어 돼지에 급여하는 생균제가 비육돈의 발육 및 질병발생에 미치는 효과와 분뇨처리효과를 구명하기 위하여 실시한 시험결과를 요약하면 다음과 같다. 생균제 혼합급여 시험은 사료에 0.1% 씩 생균제와 항생제를 각각 첨가하여 처리구별로 30두씩 3처리 평균체중이 21.4$\pm$0.54kg인 육성비육돈 90두를 공시하여 시험을 실시하였다. 0.1% 생균제 (Bacillus toyoi spore) 급여구는 육성돈에서 출하시까지 급여하였으며, 0.1% 항생제 (kitasamycin and sulfamethazine) 첨가 급여구는 출하 1개월전 부터는 항생제 첨가한 사료를 급여하지 않았다. 일당 증체량과 사료효율은 처리간에 유의적인 차이를 나타내지 않았다(P >0.05). 도체성적에 있어 출하시 체중과 도체중은 항생제 첨가급여구가 다소 높게 나타났으나 처리간에 유의적인 차이는 없었다(P>0.05). 등지방 두께는 생균제 첨가 급여구가 다른 처리구에 비하여 낮게 나타나는 경향이었다(P<0.05). 도체등급별 출현두수는 A등급 출현율에서 생균제 첨가 급여구가 다소 높은 비율을 보였다. 육안 병변에 대한 모니터링 결과에서는 생균제 급여구가 병변발생율이 적게 나타났다. 시험돈사의 환경조사에서 처리간에 온도의 차이는 없었으나 최저온도에서는 항생제첨가 급여구가 다른 처리구에 비하여 유의적으로 높게 나타났다(P<0.01). 습도는 생균제 첨가급여구가 84.34$\pm$6.03으로 다른 처리구에 비하여 높게 나타났다(P<0.01). 시험돈사내의 돈분뇨의 성상변화(BOD, COD, SS, T-N, T-P 및 암모니아 농도)도 생균제첨가 급여구가 낮은 수치를 보였다. A study was conducted to determine the effect of dietary probiotics or antibiotics on growth and pathological status in growing-finishing pigs. Ninety male pigs weaned at 24 days of age were divided into three groups of 30 pigs each on the basis of body weight and litter. Three groups of ten pigs(one pen) each were assigned to one of the following diets; a control diet or diets containing 0.1% probiotics or 0.1% antibiotics (1:1 mixture of kitasamycin and sulfamethazine). Average daily gain (ADG), feed efficiency(G/F) and the pathological status were monitored. ADG, feed efficiency and carcass quality were not different (P>0.05) among the three treatments. But pork quality in pigs fed probiotics tended to be improved, compared to other treatments. The pigs fed probiotics had lower pathological lesion in intestinal monitoring than that of other treatments pigs. The chemical composition of slurry(BOD, COD, SS, T-N, T-P and ammonia) in the probiotics treatments tended to be decreased, compared to other treatments. Results of this study suggest that dietary probiotics improve pigs' housing environment, and decrease the contents of polluting materials in slurry.

現代中立主義 小考 : Its Relation to the Reunification of Korea 韓國의 統一과 關聯하여

高文錫 漢陽大學校 1974 論文集 Vol.8 No.-

Neutralism, newly formed and manifested phenomenon after the World War Ⅱ, was nothing but a sort of political expedient to assume a neutral sttitude allying neither in the cold war between two Super Powers, the U.S. and the Soviet Union, and it has been mainly sponsored and carried out by India, Indonesia, Egypt and Yugolavia. It is not a passive desposition like traditional neutrality, which aimed at application in the war time, but a policy of non-alignment with the positive purpose of maintaining peace by preventing the collision of the two Blocs in peace time. The policy was gradually adopted by newly born countries in the South East Asia, the Middle Ease and Africa. Since the U.S. was enthuastic about the collective defence systemat at the time, this neutralism, characterized by nor alliance to any of military bloc, was encouraged by Soviet Union and Red China. In the 1960's, the international atmosphere of the peaceful coexistence prevailing, the rapid expansion of Red China's influence and the struggle between the Red China and the Soviet Union made this neutralism losing its direction for a while. However, the number of these non-alignment nations steadily increased and, thus, they have been exercising a great influence in the international politics. The peaceful coexistence between the United States and the Soviet Union was achieved by the balance of power based on their monopoly of predominant atomic weapons. But, the possession of atomic weapons by the United Kingdom, and France, and Itately by Red China altered the international politics into a multipolar system from the previous bipolar system, And it brought about a change in characteristics of the neutralism. In spite of such an international political appearance, the two Super Powers and their allies of the West and the East still hold the key to the international order and their balance of power is the main factor for the world peace which is the ultimate goal of the neutralism. These neutral nations are cautiously making their efforts to maintain the balance of power and they are eager th ashieve their economic and social development on a peaceful earth. Moreover, as relation between the U.S. and Red China was improved on the basis of agreement on the status quo in the1970's and current of alleviation of tense come to prevail all around the world, these neutral powers had to rearrange their courses appopriately with this situation and in the direction of accelerating this tendency. It might be apparent that the neutralism has nothing to do with the Republic of Korea who chose a collective defence system in an alliance with the U.S., by which she has successfully been preventing the attack from the aggressive North Korean Communists. Inspiring the neutralimn to the Republic of Korea would almost mean the plotting the subversion. However, its attitude toward the neutral powers shoud be reconsidered, and its passive approach to them should be changed to a positive approach so that friendship can be maintained with them. Therefore, one can reach the conclusion that the Korean people should make a great effort to maintain the peace in the Far East and the balance of power among the four Powers of the U.S., U.S.S.R., China and Japan as well as the East and the West, regardless to their domestic political system and structure, for their security and reunfication, and should also realize that a neutrally uni/fed Korea might be in due course.

The purposes of this study were to analyze materials for middle school chemistry gifted, used at Chonnam National University Science Education Center for Gifted. The analysis framework designed consisted of 4 factors: educational objective domains, contents of the program, emphasis of scientific thinking, and steps of inquiry process between basic course andenriched course. The results showed that all chemistry contents and concepts were not covered by the activities, and the contents of the materials contained advanced learning of the subject. The most activities were basic inquiry type, and required convergent thinking rather than divergent thinking. Therefore higher inquiry experiments and creative activities should be contained and the contents for divergent thinking should be reflected more on the materials. Regarding the openness of inquiry, 94.1 % of activities were classified to lower openness , level 1. Regarding the level of activities, only 10.4% of activities classified to creative activities, most of them came under a category of inquiry activities. The study suggests that activities need to be more student-centered to have students to think and do creatively, that we should develop the materials contained the contents required the divergent thinking and the various creativity-activities for middle school chemistry gifted. 학적 사고력, 탐구단계에 따른 과학 탐구과정 요소 등을 분석하였다 프로그램의 내용 분석은 프로그램의 단원별, 활동형태, 활동 수준, 활동의 특징, 활동의 개방도 등으로 나누어 분석하였으며, 과학적 사고력 분석은 발산적 사고, 수렴적 사고, 연관적 사고, 비 관습적 사고 등으로 나누어 분석하였다. 또, 과학 탐구과정 요소 분석에서는 탐구주제 선정, 탐구 설계, 탐구 수행, 자료 해석, 결론 도출 등으로 나누어 분석하였다.

美國의 極東政策과 韓美關係 : 舊韓末 韓美修交前後를 中心으로 American Relations in t`e bdginning of 20th century

高文錫 漢陽大學校 行政問題硏究所 1983 行政問題論集 Vol.4 No.-

Hisotrically, the foreign policy of U.S. had been based on the traditional tendencies, namely the principles of isolationism, the Monroe doctrine and Pan-Americanism. However, the United States that emerged from the war of 1898 which ended with the acquisition of the Philippine had manifested an interest in the Far East Perhaps the interest in China stemmed from somewhat romantic ideas as to the vast market that the China offered to the trade of the West, and John Hay tried to commit the powers to freedom of commercial opportunity in china and to respect for the territorial integrity of this state. And then in the fifties of nineteenth century a new phase of U.S. relations began with Japan. It was the American government which had opened Japan to the trade of the world for the first time, and it was also the United States which came to the first western power that opened official relationship with korea in 1882. American policy in korea began with economic interest and politically it pursued neutral and non-intervention policy. This means that though the U.S. insisted on the independence of korea and opposed Chinese sovereignty in korea, American-korea policy was political neutrality. Therefor the U.S. did not respond to korea's request for the American intervention in the Sino-Japanese and Russo-Japanese Wars recognized Japanese control over korea in 1905. America's national interest then was to get security of the Philippines, to maintain a balance of power for peace and stability in Asia, and to increase its economic interest to the U.S., and the two nations did not have political and economic interests. We may say that it was quite natural that the United States who believed its involvement in korea would be embarassing rather than helpful, recognized Japanese control over Korea in the Taft-Katsura Agreement and abandoned Korea for good.
