Objective : The purpose of this study was to examine the correlation between handwriting skills and praxis. Method : Participants consisted of 50 normal children who were the second-grade students at an A elementary school in Kim-hae. They didn't have a visual dysfunction, an auditory dysfunction, and a disease or an injury in arms and hands. They could follow examiners' directions properly. They were administered the Postural Praxis and the Praxis on Verbal Command of the Sensory Integration and Praxis Tests(SIPT)(Ayres, 2000) and the handwriting skill test which was made with reference to foreign literatures. It was conducted from October 19, 2004 to December 17, 2004. The data were analyzed with non-paired t-test, ANOVA, and Pearson correlation coefficient. Results : 1. Total handwriting score and praxis according to gender of children showed the statistically significant differences(p<0.05). 2. Total handwriting score correlated with praxis(p<0.05) and handwriting speed did not correlate with praxis. 3. Postural Praxis and Praxis on Verbal Command according to handwriting groups showed the statistically significant differences(p<0.05). 4. Among the standards of the handwriting skill test, accuracy of letter form, identity of letter size, spacing between letters and words, placing text on lines, error existence, and letter out of regular square correlated with the Postural Praxis(p<0.05), and accuracy of letter form, identity of letter size, and placing text on lines correlated with the Praxis on Verbal Command(p<0.05). Conclusions : The correlation between handwriting skills and praxis will help occupational therapists to provide fundamental and various treatment programs for children who are referred for the poor handwriting. But more studies in handwriting skills and praxis are necessary to decide which component of handwriting skills is related to praxis.

자연광은 시시각각 변화하며 광 특성의 변화는 계절별 시간별 일주기리듬을 갖는다. 이러한 자연광의 리듬은 인간의 감성 또는 수면-각성 패턴과 같은 생체리듬에 영향을 미친다. 인간의 생체리듬은 멜라토닌에 의해 조절되며 특히, 수면-각성주기를 일정한 수면패턴으로 유지하게 한다. 이에 본 논문에서는 자연광의 하루 주기변화에 따라 조명의 단파장 영역 중 446nm~477nm의 비율을 제어하여 심부 체온의 변화를 통해 수면패턴을 분석한다. 분석결과, 자연광의 일몰시간과 유사한 시점에서 446nm~477nm의 비율을 최소로 제어 하였을 때 수면에 긍정적인 영향을 미치는 것을 확인하였다.

The purpose of this study was to examine the relationship between the regular selling price and nutrient contents of foods used for special medical purposes in Korea. This study investigated the regular selling price and nutritional composition of 114 enteral nutrition (EN) foods on the manufacturer's internet homepage. The average price of the total products was 1,156.0 won/100 mL. The price of foods used for calorie and nutrient supplementation (CNS) was significantly higher compared to that of the other EN food types (p<0.01). With respect to the nutritional content per 100 mL of the product, EN foods for CNS had significantly higher contents of energy, protein, 5 minerals, and 7 vitamins than the other EN food types. On comparing the nutritional contents of foods according to the price, the balanced nutrition foods showed significantly higher contents of energy, carbohydrate, protein, 3 minerals, and 7 vitamins in high-priced products than in low-priced foods. Summarizing these results, foods for CNS were approximately twice as expensive as the other EN foods, and the energy, protein, mineral, and vitamin contents were also high. Balanced nutrition foods had higher nutrient contents in high-priced products, which showed the relationship between the product price and nutrient content.
