The metabolism of ginseng saponins by human intestinal bacteria was studied using human feces under anaerobic culture conditions. $Ginsenoside-Rb_1$, $-Rb_2$ and -Rc(protopanaxadiol type) were mainly metabolized to compound-K(C-K), $20-O-[{\alpha}-L-arabinopyranosyl(1{\rightarrow}6)-{\beta}-{_D}-glucopyranosyl]-20(S)-protopanaxadiol(compound-Y,\;C-Y)$, $20-O-[{\alpha}-L-arabinopyranosyl(1{\rightarrow}6)-{\beta}-{_D}-glucopyranosyll-20(S)-protopanaxadiol(ginsenosied-MC,{\;}MC)$, respectively, and $ginsenoside-Rg_1$ and -Re(protopanaxatriol type) to their aglycon, 20(S)-protopanaxatriol, though the pathway and rate of the metabolism were affected by fermentation medium. C-K was not decomposed any more, while C-Y and Mc were both gradually hydrolyzed to C-K.

In the COVID-19 pandemic era, non-contact services were demanded and the use of extended reality and metaverse services increased rapidly in various applications. In this paper, we analyze Gather.town, ifland, Roblox, and ZEPETO metaverse platforms in terms of user interaction, avatar-based interaction, and virtual world authoring. Especially, we distinguish interactions among user input techniques that occur in the real world, avatar representation techniques to represent users in the virtual world, and interaction types that create a virtual world through user participation. Based on this work, we highlight the current trends and needs of human-metaverse interaction and forecast future opportunities and research directions.

Religions have the characteristics ultimately to solve the problems of human beings. These religions are externally expressed through the behaviors called rituals and contain substantially symbolic meanings. A ritual is a kind of transcendental experiences and infinite experience conducted in the reality and formalizes external behaviors in front of the presence of holy subject. Therefore, there is no religion without rituals. However, there are insignificant differences between religions or sects in performing rituals. The purpose of a ritual for human beings who have access to the holy world and this world is to keep their balances not to excessively indulge in this world. Moreover, a ritual plays the role to exercise strict control over the daily life of religious people who are in the holy world but easily tend to be accustomed to force of habit. These rituals are closely related to belief. Belief(Conviction) is one of core elements of religion. Belief as the unique activity among various behaviors of human beings illustrates another characteristics of human beings. The common efforts in the history of mankind to overcome cultural or geographical differences through existing religions can be represented by belief, that is, the faith. On the basis of background described above, this study aims to identify the meaning of rituals and dynamic structure of belief as examining the rituals of Daesoonjinrihoe.

This paper proposes a human action recognition scheme for Intelligent Web Browser. Based on the principle that a human action can be defined as a combination of multiple articulation movements, the inference of stochastic grammars is applied to recognize each action. Human actions in 3 dimensional (3D) world coordinate are measured, quantized and made into two sets of 4-chain-code for xy and zy projection planes, consequently they are appropriate for applying the stochastic grammar inference method. We confirm this method by experiments, that various physical actions can be classified correctly against a set of real world 3D temporal data. The result revealed a comparatively successful achievement of $93.8\%$ recognition rate through the experiments of 8 movements of human head and $84.9\%$ recognition rate of 60 movements of human upper body. We expect that this scheme can be used for human-machine interaction commands in a web browser.

Radical paradigm shift is being expected due to the coming of the so-called intelligent society. In the intelligent society, things or machines are able to use intelligence for the first time in history and this will bring about fundamental changes at every corner of human society. This article analyzes views of the world in order to figure out basic directions of this paradigm shift. A dualistic view of world mediated by technology is suggested for a new world view of the intelligent society, based on comparison of a traditional dualistic view of world between human-nature and a tripartite view of world between human-machine-nature. This article summarizes paradigms of the intelligent society into four ; externalization of intelligence, productivity explosion, platform society, and self-organizing society. These new paradigms will provide lots of benefits such as intelligence augmentation, production capacity increase, and self-organizing effect. But at the same time, it will increase risks of system failure because of loss of human control on technologies. In conclusion, it is argued that human choices and efforts will decide the future of the intelligent society becuase the paradigm shift is value neutral in essence.
