By examining the relationship between physiological character of stomach and true viscera pulse(眞臟脈) with "Huangdinejing(黃帝內經)", the study shows these fallowing results. Stomach is not only one of the six bowels(六腑), it represents them. It is called as yang brightness of foot(足陽明) because it has relation with function of earth among five phases(五行), great storage(倉廩) and root of five visceras and six bowels(五臟六腑), has close relationship with triple energizers(三焦). Stomach is an important organ that feeds acquired qi(後天之氣) based on food and stomach qi (胃氣) which is a transformed form by going through digestion, is significant for life conservation. In human body, the activation of stomach qi can be known by pulse. The true viscera pulse is a pulse which predicts the period of death. If stomach qi exsits, viscera qi can be led to greater yin of hand(手太陰), however, when it does not exist, five viscera qi can not be led to greater yin of hand and this kind of situation appears the true viscera pulse. Hence, by knowing the relation between stomach qi and five viscera qi, the condition of normality, disease, and death can be known. In "Hwangdineijing" it says, stomach qi, shortly string like pulse(微弦), shortly surging pulse(微鉤), shortly floating pulse(微毛), and shortly sunken pulse(微毛) shown in four seasons are normal pulse. And also it emphasizes, normal pulse is made when four seasons, five viscera pulse, and stomach qi are in harmony. In conclusion, stomach qi is based on food for well being, and a standard of judging people whether they are living in a healthy life or not.

This study investigated the effect of artificially enhanced mesozooplankton on the phytoplankton dynamics during fall blooming period using a mesocosm in Jangmok bay located in the Southern Sea of Korea in 2001. The four bags with 2,500 liter seawater containment were directly filled with the ambient water. And then, abundances of mesozooplankton in two experimental bags were treated 6 times higher than those in control bags by towing with net($300{\mu}m$) through the ambient water. Phytoplankton community between control and experimental bags were not significantly different in terms of chlorophyll-a(chl-a) concentration and standing crop (one-way ANOVA, p>0.05) during the study period. Initial high standing crop and chl-a concentration of phytoplankton drastically decreased and remained low until the end of the experiment in all bags. Diatoms, accounting for most of the phytoplankton community, consisted of Skeletonema costatum, Pseudo-nitzschia seriata, Chaetoceros curvisetus, Ch. debilis, Cerataulina pelagica, Thalassiosira pacifica, Cylindrotheca closterium, and Leptocylindrus danicus. Noctiluca scintillans dominated the temporal variation of mesozooplankton abundances, which peaked on Day 10 in the control and experimental bags, while the next dominant copepods showed their peak on Day 7. Shortly after mesozooplankton addition, copepod abundance in the experimental bags was obviously higher than that in the control bags on Day 1, however, it became similar to that in the control bags during the remnant period. It was supported by the higher abundance and length of both ctenophores and hydromedusae in experimental bags relative to the control bags. However, the cascading trophic effect, commonly leading to re-increase of phytoplankton abundance, was not found in the experimental bags, indicating that copepods were not able to control the phytoplankton in the bags based on the low grazing rate of Acartia erythraea. Besides that, rapidly sunken diatoms in the absence of natural turbulence as well as N-limited condition likely contributed the no occurrence of re-increased phytoplankton in the experimental bags.
