19C was a chaotic time of Chosun dynasty, in order to make society stable, the scholas of Chosun wanted to define themselves as a little China on the east", to understand themselves as part of China and somehow they thought it will help for Koreans to understand who they really are. This "Chosun as a little China" idea is their spritual foundation and also the to understand who they are. From 16 C, Chosun had idea of "being a little China, so when Hwaseo talked about this idea, it was not new to the people and scholars in Chosun, however in Hwaseo's theory, the idea was more defined and realistic. In 19 C Chosun dynasty, the chaos caused by absece of fundimental principle was great, the scholars agreed Hwaseo's "Chosun as a little China" theory should be the foundational principle. Therefore, the problem of understanding and communicating about the west has to be reconcidered, because that was what they wanted to have as foundation before the comunication with west. Scholas of Chosun wanted to set their foundation before they often up their country to the west so they needed time to discuss this. In 19 C Japan on the other hand, they faced same chaos that Chosun experienced, however they went totally different way, because Japan unerstood the reallity and accepted western civilization. Specially, the latter period Mito study influenced to make that decision by changing the west from what they have to defeat to what they have to respect and copy. Both Chosun and Japan focused on making thier countries stronger, but Chosun found the answer in focusing on orthodox confucianism and Japan found the answer in making the military stronger. That is why these two countries went totally different ways in the history of 19-20 C North-east Asia.

The modern political scientist Liang, qi-chao (1873-1929), who insisted on the richness of China, was a major axis of Korean intellectuals in the nineteenth century. His patriotism for Chinese reconstruction oppressed by Western powers has greatly influenced Korea 's will to build a modern nation. There was military power and physical education at the center of Liang, qi-chao thought. He emphasized military strength through military strength with a strong stamina, so he mentioned the necessity of military and physical education. Based on the idea of this kind of Liang, qi-chao, the korean intellectuals believed that the Korean people should be born healthy through physical education. The initial introduction of physical education in Korea was integrated with the Military Sports. For the first time, Being introduced Western Sports in 1895, The fact that the army athletic gymnastics was first introduced into school education in 1896 proves this oneness. Moreover, Ethnic scholars continued to focus on fostering strong nationality through physical education based on the spirit of Liang, qi-chao, and was emphasizing the gymnastics of the military sportsman at the central idea.

This study investigated torque characteristics for Couette flow experimentally under circumstaces that ferrofluids were between two coaxial spheres. Torque measurement was obtained for the situation where the inner sphere was rotating while the outer sphere was kept stationary. The magnetic field was imposed on the fluid, using a bar magnet which was inserted in the inner sphere. In the laminar flow region the torque increase when the magnetic field is applied and the critical Reynolds number is increased. However, in the transition regime, the effect of the magnetic field on the torque characteristics decrease as Reynolds number increases. The value of torque were the same as those of glycerine solution beyond the cirtical Reynolds number. We also made experimental equation which could obtain coefficient of torque within critical Reynolds number in terms of sphere spacing Reynolds number and magnetic properties of ferrofluid.

In this paper, the SH mode of elastic surface waves which are used for delay lines of elastic surface wave is the cretically analysed. It is shown that the SH mode has very large electromechanical coupling factor and propagates on the surface with very small decaying coefficient into the medium. In the case of P2T-4, the depth cf piezoelectric medium that contains 80% of energy is 190 wavelengths. An elastic surface wave delay line is discussed from the view point of 2-port network. Center frequency is shifted by the ratio of transducer electrode width to gap between transducer ellcerodes when electromechanical coupling factor is large. Tempera _ore coefficients for bulk waves of LiNbO3 and LiTaO3 are also calculated and the minimum temperature coefficient value of delay time is 5.4X 10-6/$^{\circ}C$ ia the case of transverse wave propagating along Z axis on LiTaO3. Experimental data are in good agreement with theoretical values of the temperature coefficients of delay time for elastic surface waves propagating along X axis of 130$^{\circ}$ and 64$^{\circ}$ rotated Y cut planes of the LiNbO3.

The topic of 21st century's culture is the appearance of digital media. It made changes as big as the industrial revolution, and our society is now ruled by the digital media. The main objective of this study is to forecast the direction of current visual design education by researching and analyzing how the introduction of digital media is influencing the evolution of visual design's identity, which is an ever changing and developing science. Also, since the rain target of digital media is the young generation, the change in the method of expressing visual language is inevitable In fact, there have been a lot of changes in the methods of creating and distributing visual communication due to the introduction of digital media. In the past, most educational institutions of design had similar objectives, curriculums and teaching methods to provide education that prepares students for practical business. However, in this digital media era, the application and utilization of visual design are uncomparably diversified, and it is generally classified as interaction. The purpose of this study is to find a wat to train visual design professionals in this digital era. For this purpose, this study will identify a new educational system that fulfills the demands of this society by fusing the traditional education and the new digital education, and will suggest what an design education institute that is ahead of the demands of society should be like.

Species composition, abundance, seasonality and age composition of the fish assemblage were studied in the coastal shallow water off Shinsudo, Samchonpo. The fishes were collected by gill net from February 1984 to January 1985. Of the 32 fish species collected, the common species throughout the year were Agrammus agrammus, Hexagrammos otakii, Sebastes inermis and Lateolabrax japonicus, which comprised $73.9\%$ in numbers and $73.1\%$ in weight. The mean monthly diversity index was 1.85. The diversity was the highest in October(H'=2.25) and the lowest in April(H'=1.34). In age composition of the four species, A. agrammus and S. inermis consisted of 5 age groups from 0 to 4, H otakii consisted of 4 age groups from 0 to 3 and 1. japonicus consisted of 3 age groups from 0 to 2.

This study was tried for a mathematical approaches related to daily fluctuations in the stomach fullness of Agrammus agrammus. The specimen was collected by angling and gill net from September 1984 to August 1985 off Shinsudo, Samchonpo. Fullness of the stomachs was increased in the early morning and the late afternoon, decreased in the late morning, at noon, and during the night. That is, feeding activity of the fish was more intense at sunrise and sunset. Daily feeding activity of the fish in a day was divided into the time period of gastric evacuation and both feeding and gastric evacuation. Stomach fullness with the lapse of time in the time period of gastric evacuation was geometrically decreased. Stomach fullness in the time period of both feeding and gastric evacuation was affected by gastric evacuation rates, feeding rates, and maximum fullness of the stomach. These parameters were able to estimate from the method estimating the regression coefficient in the relationship between the time(t) and the stomach fullness$(F_t)$, or between stomach fullness at the time t and $t+\Deltat$. The rates of feeding and gastric evacuation were the highest in spring and the lowest in winter. The relationships between time(t) and stomach fullness$(F_t)$ in the time period of gastric evacuation and both feeding and gastric evacuation induced from hypotheses were respectively as follows. $$F_t=F_{to}e^{-r(t-to)}$$, $$F_t=F\infty-(F\infty-F_{to})e^{-(p+r)(t-{to})}$$

This paper is to address the consonance between Confucianism and Christianity, focusing on the first-generation clergy in Andong, North Gyeongsang Province, Korea. Andong has turned out many Confucian scholars since Yi Hwang, and thus founded the school of Togye (Yi Hwang's nom de plume). Meanwhile, some of Confucians in Andong converted to Christianity after reading the Bible. Thus, their religious activities and their interpretation of the Bible Confucian factors smacked of Confucianism, which suggests a need to reestablish the relationship between Confucianism and Christianity. This study produced the following results: First, the converts did not aspire to Christianity itself but to saving their country. The first-generation clergy in Andong wanted to sublimate their patriotic and Confucian spirits into Christianity, which is backed up by the independence movement planned jointly by Confucians and Christians in Andong. As for Confucians in Andong, their devotion to their country was a cause of the conversion to Christianity. Second, it was small wonder that Christianity was harmonious with Confucianism at least for early Christianity in Andong. In those days, Confucians in Andong had to achieve their realistic goals and thus did not need to deny Christianity. To relieve the national suffering, they had more need of Christian religiosity than Confucian morality. Likewise, missionaries wanted to propagate Christianity, and therefore did not deny the worldliness of Confucianism. On this wise, the two kept their identities and at the same time could compensate for their shortcomings from each other. This study names such Korean Christianity a 'humanistic religion.'
