[Influence of Light Source and Paper Color on the Exhibiting Preference of Traditional Calligraphy].

The Chinese calligraphy is a unique art of traditional Chinese culture. The core of color preference for Chinese calligraphy is figural preference, which is a special kind of color combination preference. Currently, the exhibition of calligraphy is always lack of scientific basis in the aspect of color science. In this research, the influence of light sources and paper color on the preference of traditional calligraphy was analyzed based on subjective and objective experiments. The relative spectral power distribution of 5 typical light sources (correlated color temperature: 2 500, 3 500, 4 500, 5 500 and 6 500 K) and spectral reflectance of 5 typical Chinese rice papers (white, orange, light white, red, yellow-white) were firstly measured and then transformed into CIEXYZ and CIECAM02 color space, respectively. Subsequently, the correlation between those colors attributes and 1 000 series of psychophysical experiment data from 40 observers on calligraphy exhibiting preference was analyzed. At last, the influence factors of the correlation were discussed form a multiple statistical point of view, such as normal distribution, correlation analysis and multiple regression. The experimental results indicated that the exhibiting preference of Chinese calligraphy is obviously different with that of ordinary color preference cases, for it is mainly affected by the attributes of lighting sources instead of the contrast of hue and lightness. The authors believe that the finding of the research will provided effective support for the development of calligraphy exhibiting in near future for museums and gallaries.

The effect of adding a home program to weekly institutional-based therapy for children with undefined developmental delay: a pilot randomized clinical trial.

BACKGROUND: Early rehabilitation for children with developmental delay without a defined etiology have included home and clinic programs, but no comparisons have been made and efficacy is uncertain. We compared a weekly visit for institutional-based therapy (IT) to IT plus a structured home activity program (HAP). METHODS: Seventy children who were diagnosed with motor or global developmental delay (ages 6-48 months and mean developmental age 12.5 months) without defined etiology were recruited (including 45 males and 23 females). The outcomes included the comprehensive developmental inventory for infants and toddlers test and the pediatric evaluation of disability inventory. RESULTS: Children who received only IT improved in developmental level by 2.11 months compared with 3.11 months for those who received a combination of IT and HAP (p = 0.000). On all domains of the comprehensive developmental inventory for infants and toddlers test, except for self-help, children who participated in HAP showed greater improvements, including in cognition (p = 0.015), language (p = 0.010), motor (p = 0.000), and social (p = 0.038) domains. Except on the subdomain of self-care with caregiver assistance, the HAP group showed greater improvement in all the pediatric evaluation of disability inventory subdomains (p < 0.05). CONCLUSION: Early intervention programs are helpful for these children, and the addition of structured home activity programs may augment the effects on developmental progression.
