    In the 2009 amendment to the course of study for schools for special needs education, the new teaching guideline "independent activities" was introduced to teach skills that ease difficulties in learning and daily living. The present study aimed to clarify compatibility between the independent activities and ICF categories by conducting a survey of teaching staff in schools for special needs education. The independent activities consist of 6 major items accompanied by a total of 26 sub-items. The ICF involves 4 components: body functions and structures, activities and participation, environmental factors and personal factors. Thirty items at the first level of classification were employed for the present investigation, excluding personal factors. The independent activities were linked not only to activities and participation in the ICF, but also body functions and structures and environmental factors. Amongst the independent activities "psychological stability" had the largest degree of compatibility with ICF items (15 items); while "health care" and "understanding situations" had the smallest number (6 items). The results suggest that a combined use of independent activities and ICF categories provides a more useful and quantitative foundation to assess the independent activities and to facilitate individual teaching plans

    Higgs potential in a minimal S3 invariant extension of the standard model

    金沢大学大学院自然科学研究科物理学金沢大学理学部Minimal S3 invariant Higgs potential with real soft S 3 breaking masses is investigated. It is required that without having a problem with triviality, all physical Higgs bosons, except one neutral one, become heavy ≳ 10 TeV in order to sufficiently suppress flavor-changing neutral currents. There exist three nonequivalent soft mass terms that can be characterized according to their discrete symmetries, and the one that breaks S3 completely. The S2′ invariant vacuum expectation values (VEVs) of the Higgs fields are the most economic VEVs in the sense that the freedom of VEVs can be completely absorbed into the Yukawa couplings so that it is possible to derive, without referring to the details of the VEVs, the most general form for the fermion mass matrices in minimal S3 extension of the standard model. We find that except for the completely broken case of the soft terms, the S2′ invariant VEVs are unique VEVs that satisfy the requirement of heavy Higgs bosons. It is found that they also correspond to a local minimum in the completely broken case. ©2004 The American Physical Society

    Associations between Mobility Restriction and Motor and Intellectual Impairments, and the Impact of Environmental Factors in Children with Disabilities

    The present study was conducted to clarify associations between motor and intellectual impairments and mobility restriction, and the impact of environmental factors on the mobility of children in residential institutions for children with motor impairments. Mobility restriction was assessed using the 1^st and 4^th qualifiers defined in the International Classification of Functioning, Disability and Health (ICF). Motor and intellectual impairments were characterized by gross motor function and intelligent quotient, respectively. The relationship between mobility restriction and the two impairments was examined using Spearman\u27s rank correlation analysis. The 1^st and 4^th qualifiers in mobility were moderately correlated to both motor and intellectual impairments. The correlation coefficient for the 1^st qualifier was somewhat smaller than that for the 4^th qualifier. The Wilcoxon signed-rank test indicated that the 1^st qualifier was significantly smaller than the 4^th qualifier in mobility (p<0.001). The present results suggest that mobility restriction is influenced not only by motor impairments, but also by intellectual impairments. The contextual assistances are considered to play an important role in reducing the impact of motor and intellectual impairments and improving mobility

    Cosmic shear statistics in the Suprime-Cam 2.1 sq deg field: Constraints on Omega_m and sigma_8

    We present measurements of the cosmic shear correlation in the shapes of galaxies in the Suprime-Cam 2.1 deg^2 R_c-band imaging data. As an estimator of the shear correlation originated from the gravitational lensing, we adopt the aperture mass variance. We detect a non-zero E mode variance on scales between 2 and 40arcmin. We also detect a small but non-zero B mode variance on scales larger than 5arcmin. We compare the measured E mode variance to the model predictions in CDM cosmologies using maximum likelihood analysis. A four-dimensional space is explored, which examines sigma_8, Omega_m, Gamma and zs (a mean redshift of galaxies). We include three possible sources of error: statistical noise, the cosmic variance estimated using numerical experiments, and a residual systematic effect estimated from the B mode variance. We derive joint constraints on two parameters by marginalizing over the two remaining parameters. We obtain an upper limit of Gamma0.9 (68% confidence). For a prior Gamma\in[0.1,0.4] and zs\in[0.6,1.4], we find sigma_8=(0.50_{-0.16}^{+0.35})Omega_m^{-0.37} for flat cosmologies and sigma_8=(0.51_{-0.16}^{+0.29})Omega_m^{-0.34}$ for open cosmologies (95% confidence). If we take the currently popular LCDM model, we obtain a one-dimensional confidence interval on sigma_8 for the 95.4% level, 0.62<\sigma_8<1.32 for zs\in[0.6,1.4]. Information on the redshift distribution of galaxies is key to obtaining a correct cosmological constraint. An independent constraint on Gamma from other observations is useful to tighten the constraint.Comment: 12 pages, 12 figures, accepted for publication in Ap

    Flame retardance-donated lignocellulose nanofibers (LCNFs) by the Mannich reaction with (amino-1,3,5-triazinyl)phosphoramidates and their properties

    Nitrogen/phosphorus-containing melamines (NPCM), a durable flame-retardant, were prepared by the successive treatment of ArOH (Ar = BrnC6H5−n, n = 0, 1, 2, and 3) with POCl3 and melamine monomer. The prepared flame-retardants were grafted through the CH2 unit to lignocellulose nanofibers (LCNFs) by the Mannich reaction. The resulting three-component products were characterized using FT-IR (ATR) and EA. The thermal behavior of the NPCM-treated LCNF fabric samples was determined using TGA and DSC analyses, and their flammability resistances were evaluated by measuring their Limited Oxygen Index (LOI) and the UL-94V test. A multitude of flame retardant elements in the fabric samples increased the LOI values as much as 45 from 20 of the untreated LCNFs. Moreover, the morphology of both the NPCM-treated LCNFs and their burnt fabrics was studied with a scanning electron microscope (SEM). The heat release lowering effect of the LCNF fabric against the water-based paint was observed with a cone calorimeter. Furthermore, the mechanical properties represented as the tensile strength of the NPCM-treated LCNF fabrics revealed that the increase of the NPCM content in the PP-composites led to an increased bending strength with enhancing the flame-retardance

    Defective function of GABA-containing synaptic vesicles in mice lacking the AP-3B clathrin adaptor

    Get PDF
    AP-3 is a member of the adaptor protein (AP) complex family that regulates the vesicular transport of cargo proteins in the secretory and endocytic pathways. There are two isoforms of AP-3: the ubiquitously expressed AP-3A and the neuron-specific AP-3B. Although the physiological role of AP-3A has recently been elucidated, that of AP-3B remains unsolved. To address this question, we generated mice lacking μ3B, a subunit of AP-3B. μ3B−/− mice suffered from spontaneous epileptic seizures. Morphological abnormalities were observed at synapses in these mice. Biochemical studies demonstrated the impairment of γ-aminobutyric acid (GABA) release because of, at least in part, the reduction of vesicular GABA transporter in μ3B−/− mice. This facilitated the induction of long-term potentiation in the hippocampus and the abnormal propagation of neuronal excitability via the temporoammonic pathway. Thus, AP-3B plays a critical role in the normal formation and function of a subset of synaptic vesicles. This work adds a new aspect to the pathogenesis of epilepsy

    Searching for dark matter halos in the Suprime-Cam 2 sq deg field

    We report the first result of weak gravitational lensing survey on a 2.1 sq deg Rc-band image taken with a wide field camera (Suprime-Cam) on the prime focus of 8.2 m Subaru Telescope. The weak lensing mass reconstruction is applied to the data to search for dark matter halos of cluster scale; M >= 10^14 solar mass. The reconstructed convergence field is divided by 1-sigma noise to obtain the signal-to-noise ratio map (S/N-map) of the detection. Local maxima and minima are searched on the S/N-map and the probability distribution function (PDF) of the peaks are created to compare with model predictions. We found excess over noise PDF created from the randomized realization on both positive and negative sides. Negative peaks imply the presence of voids in the dark matter distribution and this is the first report of the detection. Positive peaks, on the other hand, represent the dark matter halos and the number count of the halos on the 2.1 sq deg image is 4.9 +- 2.3 for S/N > 5 where the Gaussian smoothing radius of the convergence map is 1'. The result is consistent with the prediction assuming the Press-Schechter mass function and the NFW halo profile under the cluster normalized CDM cosmology. Although the present statistics is not enough due to the limited field of view, this work demonstrates that dark matter halo count via weak lensing is a promising way to test the paradigm of structure formation and cosmological model.Comment: 4 pages, 3 figures, Accepted for publication in ApJ
