This is a feasibility study for the application of the Micro- and Nano-bubbles in Thailand. In Japan, these fine-bubbles are widely used for various purposes such as products cleaning, medical treatments, food processing, fishery operations, and etc. There are several ways to produce smaller bubbles such as utilizing cavitation, a pressure discharge, an ultrasonic wave, a venturi tube nozzle and swirl flow. In this paper, these bubble Applications are concentrated to the fishery such as a catfish, fog, shrimp and etc. in Thailand, the origin place. It is the reason for concerns of the ecosystem destruction issues. Hereby, the technical, marketing, economical, business and systematical aspects are discussed.
This study examined the correct answer rate of visuospatial working memory tests between a group whose members belonged to athletic clubs to have daily exercises and a group whose members do not have daily exercises. An “n-back test” was used to assess their visuospatial working memory.
No difference was found in the correct answer rate of the whole “n-back test” between the two groups. However, as the number of memory (1back, 2back, 4back) increased, the correct answer rate decreased in both groups. Additionally, a difference was found between the two groups in only the “2back” condition. In conclusion, it was revealed that daily exercise habits could affect visuospatial working memory only in a moderate difficult condition.
