Inter-subjective relationship of higher-order among spatial-temporal wavy environmental factors - a methodological trial based on a standpoint of "relationism-first"

In this paper, first, partly is noted the suggestions by well-known philosophical emphasis of Herakleitos, Hegel etc. (i.e., several of famous other philosophers) based on their original standpoint that the truth exists not in fragmentarily individual things but only in their relational fact or process (i.e., event) itself through some concrete self-exercise of existing contradiction. That is, it is stated that a central core and/or primary existence is not in only mutual intermediation of time series type among past, present and future, but also mutual intermediation and/or relationship among different environmental factors in especially dynamic styles (more explicitly, some temporal) harmony and/or objectively latent (severe or hierarchical) contradiction. It seems true even if apparently it has no connection according to only our individual professional sense. After all, such a viewpoint of "Relationism(us)-First" seems to be exceedingly important to all things including our human being evolving after the beginning of only material nature with Big Bang. Two kinds of actual example of the above (hierarchical type) mutual correlation in the time series and mutual correlation distributed in the space among different environmental factors are considered. More concretely, the proposed method is applied especially to the acoustic environment in the actual indoor living surroundings. Then, the mutual intermediation among sound and light waves (served for utility) and leaked EM waves (served for risk) around personal computer under playing a game is investigated through some principle experiment. As the result, some effectiveness of the proposed methodology is experimentally confirmed by taking the mutual intermediation among only physical environmental factors as an example.
