This thesis is the study of the effects of Korea and China to Japan's moxibutsion formation historically and the process of Japan accepting and systemizing these effects. The method to the study is to organize the features and developments of Korea, China and especially Japan periodically by focusing on literature. Japan had traveled through China and Korea to resolve the medical problems in Japan and established a traditional medical system by interacting medical technology and publications. Korea had made a tremendous role in developing Japan's traditional medical development by accepting and making a system to China's advanced medical knowledge and books to spread these to Japan. However, Japan is the most developed from those three country for moxibustion. Through the studies of Japan's moxibustion culture and the process of the development, this thesis will present methods of development and recognition to our own traditional medicine of moxibustion.

Typical integrated service digital network(ISDN) switching systems have several shortcomings including cumulated long call set-up delay and difficulty in higher speed packet communication. The problems come from the nature of X.25 packet swiching technique used in the systems. In this thesis, to solve the above problems, the use of frame relay service within the TDX-10 ISDN switching system is proposed and a frame handling susbsystem(FHS) is designed in order to support the high speed frame relay service in the TDX-10 switching systems. In the proposed TDX-10 architecture, the 64 Kbps packet communication can be executed more ef- ficiently and high speed packet communication is allowed. To measure theperformance characteristics of the proposed systemand to compare the performance with that of the proposed system is superior to that of the existion system and to compare the performance with that of the proposed system is superior to that of the existing system. The proposed switching system offers a seamless evolutionalry path from Narrowband-ISDNto Broadband-ISDNsince itallows anefficient channelutilization and speed packet communication.

This paper aims to examine the meaning of 'Xuan(玄)' in the cosmogony, especially in the view of Yang-xiong(揚雄) and Ge-hong(葛洪). The concept 'Xuan' is thought to have originated in the XianQin text Laozi & Zhouyi. After the XianQin period, this concept has been defined as philosophical concept, and it has a variety of meanings. This paper discussed about the cause of creation, the differentiation process, and the existence principle, within the cosmogony of Yang-xiong & Ge-hong. First, the cause of creation in the Yang-xiong is efficient cause in the state of the elementary substance, but also is the principle that is applied to the phase of the creation. While the cause of creation in the Ge-hong is comprised of the cause of the creation and the existence principle. Thus, the meaning of the concept 'Xuan' in the both scholar is different from the matter monism. Second, the concept 'Xuan' in the both scholar contains the tendency of cosmogony and ontology. Yang-xiong maintains the cosmogony, but he also hold on the rudimentary view of ontology. While Ge-hong display a tendency of ontology. Third, Ge-hong accepted the view of Yang-xiong and he developed the meaning of the existence principle. And finally, the concept 'Xuan' in the both scholar forms a philosophical system. Yang-xiong insisted that the concept 'Xuan' is the basis of the universe, the human-being and the society. While through realizing the concept 'Xuan', Ge-hong tried to pursue the human-being's agelessness and the eternal life.

In the newly encountered economy caused by the Corona virus Disease-19, remote transaction becomes a new normal that disrupt traditional economic order. In the middle of the disruption, mobile tech is placed and remote finance on mobile is highly noticed and considered as an infra-tech to support the new ecology, In mobile finance. remote payment is becoming the most common service and personal identification on it is critical to operate the new service. There are various means of remotely identifying a person. Recently the use of biometric information is increasing. In this study, a correlation analysis was conducted on factors that effects to biometrics usage and the intention to use in remote personal identification. Variables for critical factor in the remote identification were classified into 4 groups such as Performance expectancy, Effort expectancy, Social influence, and Security. The empirical analysis based on the Unified Theory of Acceptance and Use of Technology (UTAUT) was conducted. The relationship between variables and the intention to use is also analyzed. In the study, stepwise regression analysis was conducted four times in which variables were adjusted in individual stage. As a result, the analysis suggests that performance expectancy, effort expectancy, social influence, security have positive effects for intention to use. Additionally, effort expectancy and security have moderating effects to intention to use depends on biometric authentication experience. The analysis has shown positive effect of variables grouped on the intention to use them. It also suggests that the intention to use biometric authentication will quickly grow. This study is expected to make a contribution to utilize and improve the use of biometric information in mobile payment.
