Objective: To learn correlation and linear relation between Perceptual Quotient (PQ) and Intelligence Quotient (IQ) by evaluating visual perception and IQ of the children with cerebral palsy and normal children, to compare the difference of the subject groups, and to use it as the preliminary study on the correlation between the visual perception and the IQ. Method: The assessment for the visual perception has been performed by Motor Free Visual Perception Test-revised (MVPT-R) twice and for the IQ by Leiter International Performance Scale (LIPS). Subjects have been 11 children with the cerebral palsy and 9 normal children, at the age of between 5 and 11. Results: Regarding the scores of the MVPT-R and the IQ of LIPS, the normal children’s scores have been higher than the one with the cerebral palsy, with meaningful statistics. There has been very high correlation between mental age and perceptual age, the IQ and the PQ, and the IQ has increased as the PQ has increased. When it comes to linear regression, the cerebral palsy has fit 65.9% while the other with the normal children has fit just 34.2%. Conclusions: There is a possibility of predicting the PQ and the IQ owing to the high correlation and the linear relation showed between the PQ and the IQ. There is a need for the activated study on the linear relation collecting the data about enough subjects through further research.

Physiological Cost Index (PCI) of walking has been widely used to predict oxygen consumption in healthy subjects or patients. The purpose of this study was to evaluate the predictability of physiological cost index of walking for the amount of exercise and cardiac function. Walking exercise was conducted in 67 healthy children (age 4-12) with a self-selected comfortable walking speed on the level surface. Walking speed was calculated, and heart rate was measured before and immediately after the walking. PCI was calculated for statistical analysis. The results were as follows; 1) The walking speed tends to increase and PCI of walking tends to decrease with age. There was significant difference in walking speed and PCI of walking among three age groups (p<.05). The change of walking heart rate tends to decrease with age, however, there was no significant difference among three age groups. 2) Linear regression equation between walking speed and age was 'Y (walking speed) = 2.124X (age) + 48.286' (=.337), (p=.00). 3) The walking heart rate tends to decrease with age. Linear regression equation between walking heart rate and age was 'Y (walking heart rate) = 143.346 - 2.63X (age)' (=.3425), (p=.00). 4) The walking heart rate decreased as body surface area (BSA) increased. Linear regression equation between walking heart rate and BSA was 'Y (walking heart rate) = 149.830 - 27.115X (BSA)' (=.3066), (p=.00). In conclusion, these equations and PCI could be useful to quantify the variation of energy expenditure of children with pathological gait when compared with age-matched healthy children.

Physiological Cost Index (PCI) of walking has been widely used to predict oxygen consumption in healthy subjects or patients. The purposes of this study were to evaluate the predictability of physiological cost index of upper extremity exercise with a sander for the amount of exercise and cardiac function and to find out most efficient speed of exercise. Upper extremity exercise was conducted in 67 healthy children (age 4 -12) for 2 minutes with a sander in two different speeds, such as self selected comfortable and self selected fast speeds. Speed of sander was calculated, and heart rate were measured before and immediately after the exercise. Physiological Cost Index (PCI) of upper extremity exercise was calculated for statistical analysis. The result were as follows; 1.　Comfortable and fast speeds of the sander went up according to the increase of age, sander PCI during exercise by it, decreased as the age increased with significant difference in each group (p=0.00). The heart rate change during exercising by it, there was no significant difference. 2.　The heart rate change during the exercise by sander increased as the speed of sander increased. Linear regression equation between the heart rate change during the exercise by sander and the speed of sander were 'Y (the heart rate change by sander) = 0.332X (the speed of sander) + 12.731' (R²= 0.154). Stepwise regression showed the speed of sander affected the change of heart rate positively, and the age affected negatively (R²= 0.242, p = 0.00). 3.　The PCI during the exercise by sander decreased as the speed of sander increased. Linear regression equation between the PCI during the exercise by the sander and the speed of sander were 'Y (the PCI by sander) = -0.00495X (the speed of sander) + 2.091'(R²= 0.267), and statistic significant was recognized (p = 0.00). 4.　The speed of exercise by sander it increased as the age increased. Linear regression equation between the speed of the sander and the age were 'Y (the speed of sander) = 2.481X (the age) -0.893(R²= 0.452), and statistic significant was recognized(p = 0.00). 5.　The reliability analysis for the method of examining each PCI, showed high reliability coefficients and the value of alpha was 0.9337. In conclusion, PCI of the upper extremity exercise with a sander could be thought to predict the energy consumption from the speed of sander as there was a linear relationship between the speed of sander exercise and heart rate change with exercise. PCI of the upper extremity exercise with the self selected fast speed was most efficient. Further study with oxygen consumption analysis is recommended to apply PCI in upper extremities in patients with different pathologies in motion.

최근 영양 생리적으로 중요성이 인정된 식이섬유가 인체내에서 나타내는 생리기능은 식이섬유의 각 구성성분들의 함량과 특성에 의해 영향을 받으므로 각 성분들을 분별 측정할 필요가 있으나 국내에서는 식이섬유의 함량을 측정한 연구가 미흡한 실정이며 특히 가열조리시 조리 전후에 있어서 식이섬유 함량이 어떻게 변화하는가에 대해서는 검토된 바 없다. 그러므로 본연구에서는 한국인이 상용하는 채소 15종(근채류 3종, 과채류 3종, 경채류 2종, 엽채류 7종)에 대해, 식이섬유 각 구성성분의 함량을 측정 비교하였으며, 각종 조리방법과 김치발효에 따른 식이섬유의 함량 변화를 조사하였다. 이 상의 결과를 요약하면 다음과 같다. 각종 채소의 불용성 식이섬유 함량은 건물 기준으로 총 불용성 식이섬유인 Neutral detergent fiber(NDF)는 11.8 ∼ 31.9 %, acid detergent fiber(ADF)는 10.9 ∼ 25.4 %, cellulose는 8.8 ∼ 23.8%, hemicellulose는 0.6 ∼ 10.6 %, lignin은 1.0 ∼ 5.2 % 범위였으며 특히 고추류에서 총 불용성 식이섬유함량이 높았다. Cellulose는 총불용성 식이섬유인 NDF의 63%정도를 차지하여 본 실험에 사용된 채소들의 경우 불용성 식이섬유의 대부분이 cellulose로 구성되어 있음을 알 수 있었다 조리시 NDF, ADF, cellulose 함량은 원료시료보다 증가했으며 이들 성분들의 변화는 cellulose의 함량변화에 기인했다. 그러나 hemicellulose와 lignin 함량은 일정한 경향을 보이지 않았다. 발효 시 NDF, ADF, cellulose 함량은 원료시료보다 약간 증가했으나, hemicellulose와 lignin은 일정한 경향을 보이지 않았다. 조리나 발효와 같은 처리에 의해 불용성 식이섬유 분획 중 cellulose만이 크게 영향을 받는 것으로 나타났다.
