Examiners for such a screening often wear white radiation hazmat suits. However, it has been reported that examinees tend to feel tension or anxiety. In this study, we focus on the color of the radiation hazmat suit as one measure to reduce residents’ tension or anxiety. This study aims to determine the common conceptions of radiation hazmat suits based on color. Methods: An anonymous self-administered questionnaire survey was conducted with a total of 262 participants consisting of nursing students, administrative staff of a university, general citizens, and mothers raising their children in the Tohoku region in Japan. The common impressions of radiation hazmat suits, which are typically white, were measured using the Multiple Affective States Scale. This scale can measure the affective state brought about by clothing. The color of white (W) was defined as a standard color commonly used for hazmat suits;in order to determine the common impressions of radiation hazmat suits based on color, the following additional colors were shown to the participants: salmon pink (P), ivory (I), and light green (G). Results: There were no sex differences regarding common impressions of radiation hazmat suits. For white radiation hazmat suits, a high score reflecting the characteristic of “capable” was obtained, while the scores for “cheerful” and “calm” were low, and those for “depressed” and “tense” were high. The colors that showed the highest score for “calm” as a positive affirmative state were I and P. W and P reflected a high “ashamed” score, and the “tense” score for G was higher for the participants in their 20s than for those in their 30s and older. Conclusions: Results show that the color of hazmat suits provokes far greater feelings of anxiety and tension on participants than previously thought. Radiation hazmat suits may be further improved based on the results of this study.展开更多

Positive relative energy PRE can be generated between quarks in protons in cold hydrogen gas in outskirts of the universe. The mechanisms for such creation of dark matter and PRE are reviewed and updated in greater detail and clearer manner. The so-generated dark matter in a galaxy can account for the galaxy’s rotation curve. Star formation in this galaxy uses up the hydrogen atoms and thereby reduces its dark matter content. Dark matter created in intergalactic hydrogen gas can form filaments. In a hypothetical model of the universe, a hydrogen atom with a small amount of negative relative energy or dark matter at the outskirts of this universe can via collisions with other atoms turn into one with a small positive relative energy PRE. Once such a sign change takes place, gravitational attraction switches to anti-gravity repulsion unopposed by any pressure gradient. This leads to a “run away” hydrogen atom moving away from the mass center of the universe and provides a basic mechanism for the accelerating expansion of the universe. This theoretical expansion and the measured redshift data are both compatible with the conception of an acceleratingly expanding universe and complement each other. But they cannot verify each other directly because the present model has been constructed for purposes different from those of the measurements. But it can be shown that both approaches do support each other qualitatively under certain circumstances for small velocities. Dark matter and PRE in the present model are not foreign objects like WIMPs and dark energy-cosmological constant but can only be created in cold hydrogen gas in gravitational field. To achieve this, infrequent collisions among the hydrogen atoms must take place. Dark matter was created first and can eventually later evolve into PRE in the outskirts of the universe and in the intergalactic void. Dark matter and PRE will disappear if the hydrogen atom carrying them becomes ionized as in stars.展开更多

Through nine times tries of marking two suits with the CAD marking module, the fabric length and rates are derived. The formulas of the marking fabric length, the length total, and the girth total are obtained by using SPSS software. Moreover, by comparing the two incorporation methods of cutting in which one in the arithmetic sequence and the other in the geometric sequence, it is found that the one in the arithmetic sequence is better than the one in the geometric sequence.展开更多
