Gifu Shotoku Gakuen University is a private university in the city of Gifu, Gifu Prefecture, Japan. Named after the 7th-century Prince Shōtoku, the school was founded in 1972 as the Gifu College of Education and adopted the present name in 1998. Its name is sometimes abbreviated to Shōtoku or Gishōdai . It has main campuses in both Gifu and nearby Hashima, as well as a junior college campus in Gifu. Wikipedia.

This paper proposes a method for low resolution QR-code recognition. A QR-code is a two-dimensional binary symbol that can embed various information such as characters and numbers. To recognize a QR-code correctly and stably, the resolution of an input image should be high. In practice, however, recognition of a QR-code is usually difficult due to low resolution when it is captured from a distance. In this paper, we propose a method to improve the performance of low resolution QR-code recognition by using the super-resolution technique that generates a high resolution image from multiple low-resolution images. Although a QR-code is a binary pattern, it is observed as a grayscale image due to the degradation through the capturing process. Especially the pixels around the borders between white and black regions become ambiguous. To overcome this problem, the proposed method introduces a binary pattern constraint to generate super-resolved images appropriate for recognition. Experimental results showed that a recognition rate of 98% can be achieved by the proposed method, which is a 15.7% improvement in comparison with a method using a conventional super-resolution method. © 2011 IEEE.

Licorice extracts are used worldwide in foods and medicines, and glycyrrhetinic acid (GA) is a licorice component that has been reported to induce various important biological activities. In the present study, we show that GA induces actin disruption and has tumor cell-selective toxic properties, and that its selectivity is superior to those of all the clinically available antitumor agents tested. The cytotoxic activity of GA and the tested antitumor agents showed better correlation with the partition coefficient (log P) values rather than the polar surface area (PSA) values. For selective toxicity against tumor cells, GA was most effective at 10 μM that was the same concentration as the previously reported maximum plasma GA level reached in humans ingesting licorice. These results suggest that GA could be utilized as a promising chemopreventive and therapeutic antitumor agent. The underlying mechanisms involved in the selective toxicity to tumor cells by GA are also preliminarily discussed. © 2010 Elsevier Masson SAS. Source

We propose a novel sequence alignment algorithm for recognizing handwriting gestures by a camera. In the proposed method, an input image sequence is aligned to the reference sequences by phase-synchronization of analytic signals which are transformed from original feature values. A cumulative distance is calculated simultaneously with the alignment process, and then used for the classification. A major benefit of this method is that over-fitting to sequences of incorrect categories is restricted. The proposed method exhibited higher recognition accuracy in handwriting gesture recognition, compared with the conventional dynamic time warping method which explores optimal alignment results for all categories. © 2010 Elsevier Ltd.

Background: This study aimed to examine age-related, interindividual, and right/left differences in anterior-posterior foot pressure ratio in 764 preschool children (364 boys and 400 girls) aged 3.5-6.5 years.Methods: Subjects maintained an upright standing posture for 10 seconds on the Footview Clinic, an instrument designed to calculate the anterior-posterior foot pressure ratio. The ratio of anterior foot pressure in each subject's right and left feet was selected as a variable, and the mean of a 10 s measurement was used for analysis.Results: The ratio of anterior foot pressure was significantly larger in the right foot than in the left foot. With regard to age, the ratio of anterior foot pressure was significantly larger in children aged over 4.5 years than in children aged 3.5 years. It was also larger in children aged 6 and 6.5 years than in children aged 4 years. Interindividual differences in variables were large, and coefficients of variance were highest in children aged 3.5 years and lowest in children aged 6.5 years.Conclusions: In conclusion, anterior foot pressure increases with age in preschool children. Interindividual differences in anterior foot pressure are large and tend to decrease with age. Furthermore, the anterior foot pressure is slightly higher in the right foot than in the left foot. These results will be useful for various studies, such as examining relationships between the anterior-posterior foot pressure ratio and factors, such as untouched toes, physical fitness, and level of exercise. © 2013 Matsuda and Demura; licensee BioMed Central Ltd.

In this paper, we analyze changes in determinants of internal long-distance elderly migration using 1960, 1970, 1980, 1990 and 2000 National Censuses. First, we show the characteristics of elderly migration. Percent of elderly migrants has risen gradually from 3.0% (1960) to 10.3% (2000). Upheaval in migration rate at elderly ages with more aged people having higher migration rates, confirmed for 1970 and clearly seen in 1990 and 2000. Migration of young old has changed from concentration toward major metropolitan areas to that toward to rural areas. On the other hand, migration of old old continues to concentrate to major metropolitan areas. The adjusted gravity model and net migration model were used in this paper. Regression analysis were used for all cases. Dependent variables were numbers of migrants (AG model) and net migration rates (NM model). Explanatory variables were (1) index of potential migration living together with/near children's household (CHI), (2) index of potential return migration to 1940 living place (RMI), (3) index of amenity (average temperature: AT), (4) number of doctors per area (DA), (5) consumer price index (PI), (6) index of potential return migration to birth places (BPI), (7) number of inmates of nursing home per population (NH). Area divisions were 10 areas and 46 prefectures. The main results of our paper are summarized as follows. Only CHI had strong explanatory power from 1960 to 2000 for both young old and old old. DA had strong explanatory power in 1960 for young old and from 1980 to 2000 for old old. For young old RMI, DA, AT and CHI had strong explanatory power in 1960, and the determinants of migration for young old changed to AT, PI, BPI and CHI in 1990 and to PI, BPI, NH and CHI in 2000. For old old the same determinant of migration for forty years was only CHI, but AT and DA had explanatory power from 1980 to 2000. Source
