The purpose of this study is to analyze the correlation between the stature and the muscle performance ratings and the subjective discomfort rations at performing lower arm's pronation and supination according to change sin the height of working table for more efficient performance at designing a working table and performing a work. For the purpose, this study conducted an experiment targeting 40 people in their 20s, who were classified into 4 groups each group composing 10 people at intervals of 5cm from the standard stature of 166.5cm. The experiment measured the maximum isometric pronation and the supination muscular power, and at measuring the factors, the heights of working tables were set as 800mm, 850mm, and 900mm. From the measurement results, it was found that the stature and the maximum muscular power was correlated. That is, as the experiment groups's average stature is higher, the maximum muscular power was higher. For the correlation between the motion patterns(pronation and supination) and the maximum muscular power, it was seen that the maximum muscular power was higher at performing the pronation than the supination. In the correlation between motion patterns and the subjective discomfort ratings, it was seen that the subjective discomfort rating was higher at performing the supination than the pronation. For the correlation between height adjustment and the subjective discomfort ratings, as the height of working table was lower, the subject discomfort rating was lower. Therefore there was no difference in the maximum muscular power according to the height changes of working table, but it was found that as the working table was higher, the user felt more comfortable.

Aquaporin5 (AQP5), a water channel plays an important role in the fluid homeostasis and cell volume control in epithelial cells. In an effort to understand fluid homeostasis in the oviduct, tissue specific expression of AQP 5 was examined together with hormonal regulation of AQP5 in the mouse oviduct. To understand the oviductal fluid homeostasis and its regulation by sex steroids, We examined AQP5 expression in mouse oviduct during developmental stage and estrous cycle, and in estrogen receptor α (ERα) knockout mice oviduct. In immature mouse oviduct, expression of AQP5 expression was examined after stimulation with gonadotropins. The effect of ERα agonist (PPT) and ERβ agonist (DPN) on the oviductal expression of AQP5 was examined in ovariectomized mouse. All samples were subjected to realtime-PCR and immunohistochemistry analysis. In oviduct epithelium, AQP5 was largely found in the apicolateral membrane and cytoplasm of ERα-positive non-ciliated cells but weakly expressed in the ciliated cells. Interstitial cells, muscle cells and blood vessels were also weakly positive for AQP5 immunoreactivity. In cyclic female mice oviductal AQP5 mRNA levels were the highest at estrous. In immature mouse oviduct AQP5 mRNA and epithelial immunoreactivity were increased by PMSG, and followed by a decrease after hCG. In ERα KO mice oviduct, AQP5 mRNA levels were significantly lower than those of WT females at diestrous stage. In immature and OVX mouse oviducts, AQP5 mRNA and epithelial immunoreactivity were significantly increased by E2 and PPT. Together, our results suggest the pivotal role of AQP5 in fluid secretion and absorption of water in non-ciliated cells in oviduct. AQP5 gene is tightly activated by estrogen – ERα signaling in non-ciliated cells in oviductal epithelium, mediating the effect of estrogen on gamete transport, fertilization and early embryo development via regulating the fluid homeostasis in oviduct.

Cryopreservation has been known as an efficient method for long-term preservation of clonally propagated plants, and several cryopreservation methods have been developed. Among them, a droplet-vitrification method for potato using axillary shoot tips in vitro has been established previously. In this study, we have optimized the procedure in which explants were submitted to a step-wise pre-culture in liquid sucrose-enriched medium (0.3 and 0.7 M for 7 and 17 h, respectively). The pre-cultured explants were dehydrated with PVS3 (w/v, 50% glycerol + 50% sucrose) for 90 min or modified PVS2 vitrification solution (w/v, 37.5% glycerol + 15% DMSO + 15.0% ethylene glycol + 22.5% sucrose) for 30 min. This two dehydration solutions produced post-cryopreservation regeneration percentages of 57.2% and 80.9%, respectively. We also compared a new post-culture medium (0.1 mg L ･ -1 GA3, 0.1 mg L ･ -1 kinetin) with the conventional one (0.15 mg L ･ -1 IAA, 0.2 mg L ･ -1 zeatin, 0.05 mg L ･ -1 GA3); the shooting initiation rates were 80.9% and 43.5%, respectively. The results suggest that the modified droplet-vitrification protocol described in this study is more effective, easier to implement, and more economical than the droplet-vitrification protocols currently used for potato.
