本発表は,集団がある課題を解決していく上で,個々の学習過程の違いが結果にどのような影響をもたらすかについて,数理的なモデルにより調べることを目的とする。学習過程としては,従来の個人主義的学習方法と,アクティブ・ラーニングに代表される構成主義的な学習方法(分人主義的学習方法)とを比較検討する。また集団が解決すべき課題としては,協調性の発展(協調関係の形成)を取り上げる。協調性は,幼児教育に関する種々の研究によって,最近特にその重要性が明らかになりつつある非認知的スキルのひとつだからである。個人主義的学習においては集団が一様になる傾向があるのに対して,構成主義的学習においては,集団に多様性がもたらされることが明らかとなる。

Although several self-administered dietary assessment questionnaires have been developed for Japanese subjects, they have seldom been validated with objective mea-sures. We validated a recently developed self administered diet history questionnaire (DHQ) with fatty acids in serum phospholipid fractions, alpha- and beta-carotenes and alpha-toco-pherol in serum as a gold standard using 86 university workers (42 men and 44 women, age-range=24-67 y). The age-adjusted Pearson partial correlation coefficients between the intakes of marine origin <i>n</i>-3 polyunsaturated fatty acids (PUPA) (crude values, energy-ad-justed values by residual method, energy density, and fat density) and the serum phospho-lipid concentrations (percentage of total fatty acids) were 0.49, 0.51, 0.52, 0.48, and 0.58, 0.69, 0.66, 0.69 in men and women respectively. The correlation coefficients between in-takes (μg/d) and the corresponding serum concentrations (μmol/L) were 0.43 and 0.40 in men and 0.42 and 0.60 in women for alpha- and beta-carotene respectively. It was -0.23 in men and -0.22 in women for alpha-tocopherol. The intakes of major foods (g/d) of ma-rine origin <i>n</i>-3 PUPA, alpha- and beta-carotenes showed a relatively high level of correlation with the corresponding serum concentrations, whereas the level was generally lower than those observed in the analysis with the nutrient intakes. The results suggest that DHO ranks individual adequately for marine origin n-3 PUPA, alpha- and beta-carotene intakes.

http://dx.doi.org/10.1007/s12199-009-0131-8Objectives : We explored the relationship between bone mineral density (BMD) and lifestyle in juveniles to identify factors leading to higher peak bone mass and prevention of osteoporosis in later life. Methods : Juveniles (1,364 students: 770 boys and 594 girls, aged 6–18 years) attending school in Hokkaido prefecture, Japan, were asked to complete a brief self-administered diet history questionnaire for 10-year-olds (BDHQ10y) providing information about personal history, lifestyle, and intake of nutritional elements. In addition, BMD and grip strength were measured. We analyzed the relationship between BMD and lifestyle factors. Results : The difference in BMD for boys was larger among the junior and senior high school groups. The difference in BMD for girls was larger among older elementary and later school children. Anthropometric variables and grip strength were strongly correlated with BMD. Having a nap-time routine was significantly correlated with BMD, but sleep time and sports club activities were not. BMD among juveniles who attained secondary sexual characteristics was significantly higher than that of juveniles of the same age who had not attained these characteristics. Calcium intake was significantly lower in senior high school students compared with other grades. Consumption of milk by senior high school boys and junior high school girls was weakly correlated with BMD. Conclusions : Our findings encourage educational interventions to counsel students to avoid weight loss and calcium deficiency. This effective intervention should begin before the higher elementary school, when juveniles have the greatest likelihood for preventing lower peak bone mass and osteoporosis.
