The purpose of this dissertation is to examine background of creation, composing method, and character of contents. was created by Kwon, Seop to reconfirm moral range of the Kiho-scholarship school and admire Kwon. Sang-ha (Kwon. Seop's uncle) through transmission of Kugok-ga when a custom handed down by Kwon, Sang-ha waned. This work, therefore, was composed of recollecting method describing each place of superb view relating to trace of life of Kwon, Sang-ha. In this work, the moralistic life of Kwon, Sang-ha don't appear directly. Hwangkangkugok, a fairyland where Kwon, Sang-ha lived in retirement. proves the moralistic life of Kwon, Sang-ha indirectly by describing his life as hermitian taste. Through this composing method and recognizant attitude, We know that was created for K won, Sang-ha, but it reveals Kwon, Seop' thought in life and it can be placed on prolongation with his work world.

This article aims to investigate the change of theories of reading and its historical meaning in the later Joseon period. Three scholar who left major theories of reading are mainly analyzed for the sake of it. Park, Se-chae(1631-1695) was a Neo-Confucianist who had the theory of reading named Dokseo-Gungliron(讀書窮理論). It was totally based on the scheme of Neo-Confucianist instruction and concentrated on mastering the moral principles with relishing the sentences of the Confucian Canons. Jeong, Yak-yong(1762-1836) was a Practical learning scholar and then criticized the moral-centric theory of reading of Neo-Confucianism. He valued much of the Confucian Canons but also focused on erudite reading so as to enlarge practical knowledge. Hong, Gil-ju(1786-1841) was a stylist and presented a severe criticism against Neo-Confucianist theory of reading as much. He thought that what we could realize with reading are the principles of the individual, not of the whole. The change of theories of reading in the later Joseon period as above reveals us the fact that the intellectual history of that period was in the process of dynamical change.

After Four-Seven debate in late 16C, Korean Neo-Confucian scholars had developed their theories on human nature and morality such as Insimdosimsoel (theories on the moral emotion and desire), Inmulsoengron(theories on human nature and animal nature), Mibalsimcheron(theories on the calm mind as the embodiment of morality). Confucian scholars had been active member of society since acceptance of Neo-Confucianism. They had the plans of social reforms on the basis of moral self cultivation from the elite Confucians to commoners. So the Confucian scholar took part in the foundation of new Confucian kingdom, the Joseon Dynasty(1392). Kwon gun(1352~1409), the famous Neo-Confucian scholar wrote Iphakdosoel(pictogram for beginer of Neo-Confucianism) which emphasized the importance of moral self cultivation and that the mandate of heaven in human nature is identical with Li, the moral principle which the origin of the human intrinsic moral ability as the basis of unity with man and heaven. He thought that ethical life is identical with mandate of heaven, so he insisted all the member of society should follow Li, the moral principle which the origin of human morality and social goodness. Also he emphasized the morality was the intrinsic and most important value of human being. Therefore ethical life became essential part of self cultivation. Joeng Ji-un(1509~1561) wrote the Chunmyongdosoel (pictogram of mandate of Heaven), the start point of Four-Seven debate in mid 16C. Joeng followed Kwon's theoretical line. He emphasized the importance of moral self cultivation and the human intrinsic moral ability. He wrote that the Four moral emotions arise from Li, the moral principle of mind, while Seven emotions arise from Ki, vital force of body. He insisted that human being should control Ki, the vital force to follow the Li, the moral principle of mind. This Korean Confucian scholars developed theories of morality and self cultivation. This theories not only show the philosophical speculation of Korean Confucian scholars but also show the social idealism and moral utopianism which grounded on the human morality. So they had trust in human morality which can guide human being into the right track to the good and peaceful society. These tendencies are main characteristics of Korean Neo-Confucianism which has seen from the begining of acceptance of Neo-Confucianism. Some modern philosophical criticism which insist the Korean Neo-Confucian theories such as Four-Senven theories was indulged in academic discussion are not only neglect the historical realty but also ignore the potential of Korean Neo-Confucian heritage.

This is a dimensionless analysis of interior ballistics for the design of gun tube. One of the characteristics of this analysis is to ues the .ETA.$_{j}$ number which means a relative quantity of virtual work to the kimetic energy of projectile at the muzzle. In order to apply the concept of virtual work, it is assumed that the projectile is moved from the beginning to the end of bore under constant pressure of the certain travel distance of projectile. The principle of the analysis is induced from the Le Duc equation, which expresses velocity as a function of projectile travel and is based on the translation of a hyperbolic curve. From this non-dimensional analysis, the optimum design parameters of pressure in the bore, velocity and acceleration of projectile can be obtained from the table of figure without computation. This method was verified by the experimental work.k.

The design concepts using vibration reduction techniques, or structural control, have been proposed recently to protect infrastructure against earthquakes. The magnetorheological(MR) fluid damper is one of the most promising new devices for structural vibration reduction because of its mechanical simplicity, high dynamic range, low power requirement, large force capacity and robustness. In this study, the seismic performance of MR devices are compared with that of NZ systems as an attempt to provide some data for improving seismic design techniques applied to structures. For nonlinear time domain analysis of a base isolation system, a six-story building model is considered as a numerical example. The ground acceleration data of El Centre 1940, Mexico City 1985 and Kobe 1995 earthquakes are used as seismic excitations. The results show that MR damper systems for outperform NZ systems in wide-ranging seismic excitations with respect to intensity and period characteristics.

As the use of computer has become popular it is now essential also in designing tools that the common design tools we have been using are now disappearing. The educational institutions have long started using computers as teaching materials to help students adjust to the real world. Let us introduce a new educational method in drawing, one of the basic courses, using imputer application softwares together with application of the conventional drawing instruments.

What I wish to show in this paper is the moral educational implication on "The Minor Annotations of Elementary Learning(小學枝言)" in a position to consider the alternatives about personality education problems by searching viewpoints on moral training theory on the book. "The Minor Annotations of Elementary Learning(小學枝言)" was written by Dasan Jeong-yakyong(茶山 丁若鏞, 1762-1836). In the oriental philosophy, a moral training theory is built on the base of human nature theory. Dasan's moral training theory was also built on his human nature theory. Undoubtedly we could consider that his difference from the moral training theory of Confucianism is reflected in his moral training theory putting stress on practice. Dasan criticized the moral training theory of Confucianism because of its static aspect contemplating mind internally. He stands on the position that the virtue can be come true by the concrete practice. The establishment ground of Dasan's moral training theory is on his theory of human nature's preference(性嗜好說). Dasan didn't consider benevolence, righteousness, propriety, and wisdom(仁義禮智) as human nature. He considered that the human nature prefers goodness. So there is no perfect human nature or principle originally to human beings but also directionality to be displayed. We can say that the virtue building by cultivation of directionality get connected to moral training theory. Dasan considered ?The Minor Annotations of Elementary Learning(小學枝言)? as a practice book for moral training which develops individuals' personality through practice in the reality. He thought that the book cause individuals to follow 'the elementary way(小道)' and to learn 'the elementary art(小藝)' more than academic pursuit. From this viewpoint he showed the practice(行事) of judgment(權衡) by keeping the attitude for the scripture interpretation to pursue the right principles(義理) based on Chinese exegetics(訓?) and the historical evidences(考證) through the whole book. And in the book he suggested the standard of the whole-person education to develop the human nature based on his theory of human nature's preference(性嗜好說), to cognize relationship as an ethical existence, and to pursue the harmony with graphonomy(字學) and Ethics(道學). So we can regard that he realized his practice centered moral education philosophy in the book.

The Purpose of this paper is, through the character-figuration aspect of existing Yeoheon Jang Hyungwang(旅軒 張顯光, 1554~1637)-related folk tales, to determine the relation between the people's awareness on Yeoheon and the change in the folk tales. Only 4 pieces of Yeoheon-related folk tales are existed ; ; Forgiving a rude son of the provincial governor generously. ; Predicting 'the frost of May' and Preventing the cold-weather damage, when he served as Euiseong governor, and ; The folk tales of origins of the place name - Chimabawi Rockand Yeoheondae. shows the great scholar's liberal-hearted and generous personality. One day Jang Hyungwang looked shabby and a young person was quite rude to him. But Jang Hyungwang forgive him generously. Also Yeoheon teach him the thrift and modesty. described him as a governor filled with a love for the people. He tried to edify the people with the Confucian ethics and improve the life's work of the people. embodied him as a government official of high integrity. When his wife received the silk slip from the people, as farewell gift, he ordered his wife return that. and show the images of the Predicting the future and an extraordinary moralizer. Generally These folk tales are based on his personality, whereabouts and the real case. So we could find his images in the folk tales are close to his actual feature - thrift, modest, noble-minded, well-versed in Iching and practicing moral statesmanship.
