In this paper, a target extraction using stochastic image models is proposed. The observed images are considered to be made up of three stochastic models. The first model is in charge of the noise component and is assumed to be independent identically distributed Gaussian. The labelling of two regions (i.e., the object and the background) in the second model is to obey Gibbs Random Field (GRF). Finally, we adopt a population parameter to represent the ratio of the size of the object to that of the background. The population parameter is to ease the tendency of producing similar-sized segmentations. Establishing the stochastic models, we incorporate the maximum a posteriori (MAP) estimation to determine the region labels. The optimization of the MAP creiterion is achieved by a deterministic relaxation method to converge quickly to a local maximum.

In this study, to utilize domestic fly-ash of bituminous briquette order, on the basis of the elementary experiment value, early strength and long term strength of high performance lightweight mortar was experimented by comparison method. The results are as follows : 1. As a result of mix proportion change as 1:1, 1:2 and 1:3, it showed better result than the case that fly-ash is not inputted, in long term strength. 2. If fly-ash is used as a admixture of mortar and concrete, early strength gain is difficult, but in case of mix proportion control which amount of fine aggregate is decreased and same amount of unit cement content is inputted, improvement of early strength and long term age strength is shown in compressive strength appraisement by age. 3. As a result of long term strength gain improvement and fly-ash is substituted for 3types by grade classification method, the best strength ratio is appeared in type 1.

Actinomycin D가 흰쥐 원생식세포 이동에 미치는 영향에 관한 조직화학적 미세구조 관찰

최치용,최춘근 연세대학교 자연과학연구소 1984 學術論文集 Vol.13 No.-

본 연구에서는 임신한 쥐에 Actinomycin D를 투여하여 원생식세포의 분포로써 이동경로와 시간을 조사하였으며, 각 이동경로에 따르는 형태학적 차이와 미세구조의 변화를 alkaline phosphatase로 조직화학적 방법으로 처리하여 전자현미경으로 관찰하였다. 그 결과 흰쥐 발생과정에서 원생식세포는 수태 9일째 난황낭의 내배엽 세포에서 유래하여 수태 11일째 후장을 지나며 수태 13일째에는 배측장간막을 경유하며 수태 14일째 생식융기에 도달하였다. 또한 원생식세포가 후장과 생식융기에 있을때 alkaline phosphatase 에 대한 양성반응이 크게 나타났으며, Actinomycin D를 투여하였을 때에는 이에 대한 반응이 현저히 줄어들었다. 원생식세포의 형태학적 변화로 pseudopodia 와 tail process는 후장과 배측장간막을 지날때에 가장 잘 나타났으며, 이때에는 trailing cytoplasm도 잘 볼 수 있다. 그리고 특수한 세포소기관인 nuage는 발생 초에는 나타나지 않고 이동함에 따라서 많이 나타났다. 본 실험의 결과를 통하여 원생식세포의 이동은 세포형태의 변형에 의하여 진행되며, 이러한 특징이 Actinomycin D에 의하여 손상을 입었을 때에 원생식세포의 이동이 억제되었다. 따라서 이와 같은 현상이 원생식세포가 이동할 수 있는 형태학적 특징임을 확인할 수 있다. In this study, pregnant rats were injected with Actinomycin D and the reaction of Alkaline phosphatase was used for identifying the Primordial germ cells (PGCs). So the pathway and date of migrating PGCs were observed light microscopically as the distribution of PGCs, and ultrastructural changes were observed electron microscopically during migration of PGCs. At the 9th gestation day, PGCs were observed among the endodermal cells of yolk sac, at the 11th gestation day, PGCs were seen in the hindgut and then entered the dorsal mesentery by the 13th gestation day, and at the 14th gestation day, the genital ridges were populated with them. When PGCs located in the hindgut and genital ridges, the positive reactions of Alkaline phosphatase were dominated, in the case of Actinomycin D treatment these reaction were lessened. It appeared such as pseudopodia, tail process, trailing cytoplasm and nuage as the ultrastructural characteristics of PGCs. In addition, these morphological features were damaged by Actinomycin D treatment. In these results, it was convinced that migration of Primordial germ cells went through these morphological features.

企業公開論 : 5·29措置를 中心으로 relative to the 5·29 executive measures in particular

金址郁 건국대학교 1974 樂圓誌 Vol.9 No.1

In view of the fact that the corporations of our country are now being compeled to disclose themselves to the public, the writer tried to define the meaning of disclosure of corporations as being disclosure of accounts along with dispersing or disclosing their stocks to the public. I emphasized that the disclosure of accounts would contribute to protecting the interested parties around the corporations and simultaneously expediting the rationalization of management through the introduction of external audit system. On the other hand, I suggested that through dispersing the stocks of close corporations to the general investors and also financing themselves directly from the stock investors instead of private money lenders, they could not only attain their object of rationalizing their management but also enlarge themselves. I urged, however, that this problem should be solved by the disclosure of accounts prior to the dispersing of stocks and that the disclosure of accounts must be done step by step and not in a hurry from the view point of Korean economic stage. As for the dispersing of stocks, I foresee that it would be achieved by the development of the stock market where stocks will be transacted smoothly under the adequate appraisals of the general investors for the stocks. Thus, I appreciate very highly the current 5.29 executive measures as being a most reasonable policy which will expedite a long stride development of Korean enterprise. However, I consider that it would be more advisable to adopt the method of step-by-step rather than that of a hurry. By C.W.Kim

孫文의 民主主義 理論에 關한 小考

安致淳 淑明女子大學校 1973 論文集 Vol.13 No.-

The primary purpose of this paper is to expose the ideological backgrounds of Sun Yat-sen's(孫逸仙) theory of democracy, and to discuss the distinctive characteristics of his theory mainly on the basis of his lectures on San Min Chu I (三民主義) (1) Brought up in the Confucian tradition, Sun Yat-sen always took pride in China's intellectual heritage and wanted to use it as a basis to develop a doctrine to meet the demands of modern times. For this reason, his theory of democracy was heavily influenced by the traditional Chinese political thought. First, Sun justified the necessity of practice of democracy in China not only in terms of the world-wide tendency toward democracy, but also in terms of democratic ideals cherished by the old Chinese saints such as Confucius and Mencius. Second, Sun's idea of inherent inequality of men, which is one of the unique aspects of his theory of democracy, in the main coincident with Confucius teaching. Chinese tradition was not, however, the only influence which was brought to bear on Sun's thinking. In terms of studies, contacts and foreign experiences it cannot be denied that he was at the same time profoundly affected by the Western political philosophy. Thus, he did not hesitate to say that China's tide of revolutionary ideas came from Europe and America, and suggested that China learn from the experiences of Western democracies, such as the United States and Great Britain. This does not mean, however, that Sun was uncritical of Western democracies. In fact he found fault with the machinery of Western democratic government as well as some of the ideas of Western political thinkers such as Jean Jacques Rousseau. All in all, his intention was to use Western experiences as materials for study, and to work out a program to make “China into a nation under complete pepular rule, ahead of Europe and America.” (2) The unique aspects of Sun's theory can be treated, roughly speaking, under the headings of individual v. national liberty; inequality of men in ability; Ch an(權) and Neng(能) and political tutelage. (a) Individual v. National Liberty. Far from advocating democracy as a means of securing greater freedom for the individual, he laid his stress upon China's need to secure a collective freedom for the people. Sun had himself defined liberty as follows: "Liverty, to put it simply, means the freedom to move about as one wishes within an organized group." China, disorganized, had no problem of individual liberty, There was, as a matter of fact, too much liberty. In Sun's view, what the chinese had to do was to sacrifice some of their individual liberty for the sake of the organized nation. (b) Inequality of Men in Ability. Sun presented two bases for a class of ideologues: one, theoretical, and derived from the Chinese tradition; the other, applied, which is either of his own invention or derived from Western sources. The class of ideological reformers proposed in what may be called the applied aspect of his theory was to be organized by means of the party dictatorship of the Kuomintang(國民黨). His other basis for finding a class of persons whose influence over the ideology was to be paramount was more theoretical, and deserves consideration among the abstract aspects of his doctrine. He divided men into three classes "the geniuses," "the followers," and "the unthinking" according to their innate ability. The harmony of this conception with the views of Confucius is evident. Sun, although bitterly opposed to the mandarinate, could not rid himself of the ago-old Chinese idea of class organization on a basis of intellect. The aristocracy of intellect is not to be judged, however, by the old criteria. Unlike the serene, conservative scholar-rulers of China in the past, the genius leader in the theory of Sun Yat sen was the discover or social engineer akin to the romantic Western pioneers and inventors. To those accusomed to the Western concept of democracy, Sun's division of men into three classes would seem to invalidate any future advocacy of democracy. But Sun displayed a sort of creativeness in his effort to reconcile the leadership of the intellectual class with democracy on the basis of his theory of Chu"an(權)and Neng(能). (c) Chuan(權)and Neng(能). Applied to the individual, contrast between Ch an and Neng is between the ability to have political rights in a democracy and the ability to administer public affairs. Applied to the nation, the contrast is between sovereignty and administration. According to Sun, Chuan would be given to the people, while Neng should be put entively in the government organs which comprise men of ability. But how should the unthinking, who would possess Chuan, be granted that right without attempting to usurp Neng? This was to be accomplished by two means. First, the Four powers-election, recall, initiative, referendum were to be given to the people, in order to assure their possession of Chuan Second, the Five Rights-legislative, executive, judicial, examining, and controlling are to be given to the government so that the government might be protected in its right to Neng. In Sun's view, such governmental system would make it possible that the people who rule will not necessarily govern, and the benefits of aristocracy will be obtained without its cost. (d) Political Tutelage. As the means of bringing the Chinese people to the point where they could exercise sovereignty effectively, Sun prescribed a period of political tutelage by the Kuomintang. According to his practical programs of democracy, tutelage was to lead, hsien by hsien into democracy. When more than one half of the provinces in the country reached the stage of local self-government, constituional government was to be inaugurated and the expedient of party dictatorship dispensed with. In conclusion, the democracy which Sun Yat-sen advocated is, roughly, a modernization of the old Imperial system with the Emperor removed, and the majority placed in his stead. In other words, the rule of the son of Heaven (sofar as it was government at all) was to be replaced by the rule of the whole people. To Sun Yat-sen, therefore, the essential continuity of Chinese civilization was not to be broken; democracy in China had to be not only democracy, but Chinese as well. It is not, therefore, strange to find the ancient institutions of the Empire surviving by the side of the most extreme methods of popular government. Sun's theory of democracy as such sunk into obscurity without having a chance for a full trial due, among other things, to the power-blind struggle among the warlords from 1916 to 1925 and the lack of democratic zeal on the part of the Chinese leadership in the ensuing period.
