Characteristics of relationship itself play an important role in determining well-being of individuals who participate in the relationship. We used efficacy expectations mutually shared between close friends or romantic partners as a characteristic of relationship and investigated its impact on their life satisfaction. In Study 1, we conducted a cross-sectional study among 137 pairs of close same-sex friends to test whether the efficacy expectations shared between friends are associated with levels of life satisfaction. In Study 2, we conducted a longitudinal study among 114 heterosexual romantic couples to test predictive validity of the efficacy expectations shared between couples predict levels of life satisfaction 2 month later. In both studies we found a consistent result that as degrees of the efficacy expectations shared between individuals in a relationship increased, the degree of their life satisfaction also increased. Underlying mechanisms that explain how characteristics of relationship itself increase life satisfaction are discussed. © 2016 Asano et al.

The liverwort Marchantia polymorpha is an emerging model plant suitable for addressing, using genetic approaches, various evolutionary questions in the land plant lineage. Haploid dominancy in its life cycle facilitates genetic analyses, but conversely limits the ability to isolate mutants of essential genes. To overcome this issue and to be employed in cell lineage, mosaic and cell autonomy analyses, we developed a system that allows conditional gene expression and deletion using a promoter of a heat-shock protein (HSP) gene and the Cre/loxP site-specific recombination system. Because the widely used promoter of the Arabidopsis HSP18.2 gene did not operate in M. polymorpha, we identified a promoter of an endogenous HSP gene, MpHSP17.8A1, which exhibited a highly inducible transient expression level upon heat shock with a low basal activity level. Reporter genes fused to this promoter were induced globally in thalli under whole-plant heat treatment and also locally using a laser-assisted targeted heating technique. By expressing Cre fused to the glucocorticoid receptor under the control of the MpHSP17.8A1 promoter, a low background, sufficiently inducible control for loxPmediated recombination could be achieved in M. polymorpha. Based on these findings, we developed a Gateway technology-based binary vector for the conditional induction of gene deletions. © The Author 2015.

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.

Visually induced illusory self-motion perception is termed vection. We measured vection strength in participants wearing either wooden or iron clogs together with or without a weight-jacket (four conditions). We hypothesized that the heavier items would inhibit vection more because they make locomotion difficult. Results partially showed that the iron clogs could inhibit vection. We concluded that cognition of the fact that the heavier iron clogs made locomotion difficult might function as an inhibitor of vection, suggesting that cognition can alter vection strength. © 2013 Koninklijke Brill NV, Leiden.

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.

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.

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.

We propose a method for detecting general obstacles on a road by subtracting present and past in-vehicle camera images. Compared to the existing learning-based methods that could detect only specific obstacles, the proposed method based on image-subtraction could detect any kind of obstacles. To achieve this, the proposed method first realizes a frame-by-frame correspondence between the present and the past in-vehicle camera image sequences, then performs a road surface registration between the corresponded frames. Obstacles are detected by using the difference of the road surface regions. To demonstrate the effectiveness of the proposed method, experiments were conducted using several image sequences captured by an actual in-vehicle camera. The experimental results showed that the proposed method could detect general obstacles accurately at a distance enough to safely avoid them.

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.

The study investigates the effects of foreign ownership of a domestic firm on the establishment of environmental policy under an oligopolistic market. We also compare two types of environmental policies: environmental standards and tax. We find that complete foreign ownership decreases welfare under both environmental regulations. In addition, the equilibrium environmental standards become more severe and environmental tax rates decrease as the number of domestic firms, which are solely owned by domestic investors, increases. Furthermore, if there are more than two domestic firms, the combination of foreign ownership restrictions and a lax environmental tax increases welfare. © 2010 Springer.
