This study introduces a potential technique for Japanese kana characters on tactile information display device (tactile display) that allows the user effectively perceived. Currently tactile display has not been developed for the purpose of character information transmission due to poor performance of recognition rates in terms of characters. The purpose of this study is to evaluate a novel technique, flick motion based display, for presenting Japanese kana characters on the tactile display (FMR tactile display). Flick motion is normally used as an input scheme for mobile devices, as one of touch screen gestures. In Japan, a set of flick motions on 10 isolated areas on the touch screen is especially assigned as Japanese kana character entry. Many Japanese mobile phone users have its mental model, which was applied to present character information as an output scheme into tactile display. Experiments were conducted to evaluate how the implemented presentation system can perform well to let the user perceive kana characters. A total of 10 subjects, including users unfamiliar to FMR, participated in the study. The subjects located their right hand on the tactile display and a kana character by using FMR was given on the display. They responded the characters as soon as they perceived. Number of correct recognition of the characters were obtained throughout the set of trials consisted of 20 character presentations. The results showed that the average correct recognition rates were 41.5 percent and the average reaction time was 6.8 seconds, which were faster than conventional trace-based character representations. The results suggested that fine adjustment of the palm to the tactile display and changing stimulus duration would improve the performance of recognition rates.

Objectives: The purpose of this study is to evaluate the effects of teriparatide (TPTD) on bone mineral density (BMD), bone strength, and bone quality in Akita mouse models of diabetes mellitus. Methods: Twelve-week-old female Akita mice and control mice (C57/BL/6NCrSlc) were divided into 4 groups: control mice treated with vehicle (n ¼ 7) or TPTD (n ¼ 6); and Akita mice treated with vehicle (n ¼ 6) or TPTD (n ¼ 7). TPTD or vehicle was administered subcutaneously 3 times a week for 8 weeks. Blood glucose, serum sclerostin, total tibial BMD, femoral shaft bone strength, and bone quality using Fourier-transform infrared spectroscopy imaging were evaluated. Results: No significant differences in serum sclerostin levels were evident among these groups after 8 weeks of treatment. TPTD significantly increased BMD in control mice (þ12.7%, P ¼ 0.02) and Akita mice (þ29.2%, P ¼ 0.001) compared with vehicle. Maximum load and stiffness were significantly higher in Akita mice treated with TPTD than in Akita mice treated with vehicle (þ56.6%, P ¼ 0.03 and þ 90.5%, P ¼ 0.02, respectively). On Fourier-transform infrared spectroscopy imaging, the mineral/matrix ratio was significantly lower in Akita mice treated with vehicle than in control mice (12.2%, P ¼ 0.02), and TPTD treatment significantly increased the mineral/matrix ratio (P ¼ 0.003). Conclusions: TPTD thus improved BMD and bone strength in both control mice and Akita mice, with improvements in the mineral/matrix ratio among Akita mice.

Peroxisome proliferator activated receptor (PPAR) is a nuclear receptor that is one of the transcription factors regulating lipid and glucose metabolism. Fermented ginseng (FG) is a ginseng fermented by Lactobacillus paracasei A221 containing minor ginsenosides and metabolites of fermentation. DNA microarray analysis of rat liver treated with FG indicated that FG affects on lipid metabolism are mediated by PPAR-α. To identify a PPAR-α agonist in FG, PPAR-α transcription reporter assay-guided fractionation was performed. The fraction obtained from the MeOH extract of FG, which showed potent transcription activity of PPAR-α, was fractionated by silica gel column chromatography into 16 subfractions, and further separation and crystallization gave compound 1 together with four known constituents of ginseng, including 20(R)-and 20(S)-protopanaxadiol, and 20(R)- and 20(S)-ginsenoside Rh1. The structure of compound 1 was identified as 10-hydroxy-octadecanoic acid by 1H- and 13C-NMR spectra and by EI-MS analysis of the methyl ester of 1. Compound 1 demonstrated much higher transcription activity of PPAR-α than the other isolated compounds. In addition, compound 1 also showed 5.5-fold higher transcription activity of PPAR-γ than vehicle at the dose of 20 μg/mL. In the present study, we identified 10-hydroxy-octadecanoic acid as a dual PPAR-α/γ agonist in FG. Our study suggested that metabolites of fermentation, in addition to ginsenosides, contribute to the health benefits of FG.

This article proposes a novel wireless channel estimation method suited for fast fading environment. Generally, forward error correction (FEC) requires long block code length to raise error correction capability while it deteriorates the channel tracking accuracy in pilot-aided estimation. To meet these trade-off demands, we propose a frame splitting and decision directed channel estimation (DDCE). It splits information data in half and estimate channel state information (CSI) of the former part. That of latter is simply extrapolated using the former CSI. Computer simulation result shows that the proposed method can improve bit error rate performance even at fast fading environment.
