近年南アジア諸国では、多様な供給主体による教育の普及がみられる。本プロジェクトでは現地調査と統計分析に基づき、多様な教育供給が広範な人々の教育への期待を活性化させているものの、教育格差はむしろ再生産される傾向があり、雇用市場の制約のもとでとくに中等教育~非エリート高等教育のモビリティ拡大機能は限定的であること、教育改革では市場原理の導入とともに格差是正や子どもの権利が重要課題となっていること、を明らかにした。

Appearance of the dominant peak-frequency in body sways during standing was retrospectively investigated in patients with spinocerebellar degeneration (SCD). Subjects tested were 25 patients with SCD (16 men and 9 women, ranging in age from 25 to 80; mean 55.8±15.4 yr). The disease types comprised SCA3 (n=5), SCA 6 (n=3), MSA-C (n=12), and an unknown type (n=5). Stabilometry was performed in each patient, who was asked to stand upright with a closed stance, with eyes open and eyes closed, using Anima's stabilometer G6100. The sampling time was 50 ms (20Hz) and the correcting time was 60 s. The peak-frequency was measured based on the power spectrum using the maximum entropy method (MEM). Total locus length, envelope area and velocity-vector of movement of the center of foot-pressure were also measured.The first or main peak appeared in a low frequency range between 0.10 and 0.59Hz in most of the cases with eyes open and eyes closed. It was detected in the lateral direction in 24 patients of the total number (96.0%) and in the anterior-posterior direction in 22 patients of the total (88.0%).The body sway of a frequency of 3Hz was detected in 4 patients (16.0%). Among them, the peak in the lateral direction was observed in 2 (8.0%) with eyes open or closed (one with SCA 6 and one with an unknown disease type). The peak in the anterior-posterior direction was detected in 3 (12.0%) with eyes open or closed (one each with SCA 6, MSA-C and an unknown disease type); in these subjects, the values of the total locus length divided by envelope area were more than 40.The dominant peak-frequency of 3Hz in body sways during standing did not frequently appear in patients with SCD, but it is suggested to be one of characteristic balance disorders in the disease.
