Interest in the rheology forming technology for fabrication of light weight materials and for
resolving environmental issues has been growing in industrial and academic society. In this study,
the helical shape stirrer was designed to produce rheological material. The experimental variables,
which were stirring time 0-1200 sec, stirring velocity 0-100 rpm and melt temperatures for semisolid
states, were established. The rheological materials were produced under established
experiment conditions, and then mechanical properties were measured. Sequence-production
equipments were appended to fabrication system of rheology material to make rheology materials
continuously. Therefore, the development of sequence-production system equipped with a specially
designed mechanical stirrer in spiral shape was necessary for fabricating fine grains and their
uniform globular rheology materials. The thixoforging was experimented with rheological A6061
wrought aluminum alloy fabricated by the spiral shape stirrer. Microstructural morphology of the
forged samples was investigated and their mechanical properties characterized.
The purpose of this study was to investigate the effects of senior lifestyle on health promotion behavior and to investigate the mediating effects of health control behavior on these relationships. For this purpose, an online survey (under Corona 19 Pendemic Situation) was conducted from July 18 to August 20, 2021 for seniors in their 50s, 60s and 70s, and finally 412 data were used for analysis. The collected data were analyzed by SPSS for Win 27.0 and the mediating effect was analyzed by hierarchical regression analysis. The main results of the study are as follows. First, it was confirmed that senior's lifestyle had a positive effect on health promotion behavior. Second, health control behavior had a positive effect on health promotion behavior. Third, it was confirmed that the mediating effect of internal and other dependent health control behavior was significant in the relationship between lifestyle and health promotion behavior. Fourth, it was confirmed that the mediating effect of accidental health control behavior was not significant in the relationship between lifestyle and health promotion behavior. Based on this, this study suggested the necessity of changing into internal and other dependent health control behaviors in order to maintain health when the health control behaviors of accidental tendencies are high. In this study, the degree of internal and other dependent health control behaviors and the degree of tendency of accidental health control behaviors were diagnosed and educated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
