목적 : 본 연구는 편마비성 뇌성마비 환아들의 편마비측 상지길이 단축의 정도를 평가하고, 길이 단축과 근경직도 및 운동기능과의 연관성을 알아보고자 하였다. 연구방법 : 30명의 편마비성 뇌성마비 환아(남아 13명, 여아 17명, 평균연령 6세 4개월)와 17명의 대조군(남아 9명, 여아 8명, 평균연령 6세 2개월)을 대상으로 하였다. 상지의 상완골,척골, 요골, 두 번째와 다섯 번째 중수골의 길이를 단순방사선 촬영을 통하여 길이 측정을 하였고, 건측(대조군에서는 우성측) 대비 편마비측(대조군에서는 비우성측)의 단축의 정도는 백분율로 나타내었다. 근경직도는 Modified Ashworth Scale (MAS)를 이용하였고, 상지의 운동기능은 Quality of Upper Extremity Skills Test (QUEST)를 사용하였다. 결과 : 대조군에 비하여 환자군에서는 편마비측 상지길이의 백분율이 의미있게 단축되어 있었다(p<.05). 이러한 상지길이의 단축 정도와 근경직도의 증가 및 운동기능의 저하는 의미있는 연관성을 보였다(p<.05). 결론 : 편마비성 뇌성마비 환아에서 보이는 편마비측 상지길이의 단축은 근경직 및 운동기능과 의미있게 연관되어 있다. 추후 이러한 환아들에게서 근경직도의 완화 및 운동기능의 향상을 도모하는 재활치료 후 변화되는 상지길이의 단축 정도를 연구한다면 재활치료의 효과를 좀더 객관적으로 증명하고, 치료의 방법과 정도를 정립하는데 도움이 될 것이다.

The purposes of this study are to evaluate the development of disabled children us- ing LAP(Learning Accomplishment Profile) and to investigate the correlation between subtest scores of LAP. The development scores were obtained using 244 items in 5 su-btests (gross motor, fine motor, cognitive, language/cognitive, and self help) of LAP in 34 children with delayed development from February, 1998 to March, 1999. The birth history and risk factors for developmental disablilty such as prematurity, hyperbilirubi-nemia, low birth weight, and seizure were evaluated. Collected data were analized by Pearson's correla tion coefficient and Mann-Whitney U test. The results were as follow : 1) Among the subtests of LAP scores, fine motor, language/cognitive, and self-help were signi ficantly correlated with the cognitive subtests scores (p > 0.001) 2) On the other hand, gross motor subtest scores were independent to cognitive sub-test scores. 3) The children who had history of seizure during neonatal period showed significantly low scores in language-naming, fine motor-writing, and self help-eating. The LAP is considered as a useful tool to evaluate the cognitive development disab- led children. Cognitive function significantly influence on other developmental areas es-pecially on fine motor development.

Surface complexation models(SCMs) have been performed to predict metal ion adsorption behavior onto the mineral surface. Application of SCMs, however, requires a self-consistent approach to determine model parameter values. In this paper, in order to determine the metal ion adsorption parameters for the triple layer model(TLM) version of the SCM, we used the zeta potential data for Zeolite and Kaolinite, and the metal ion adsorption data for Pb(Ⅱ) and Cd(Ⅱ). Fitting parameters determined for the modeling were as follows ; total site concentration, site density, specific surface area, surface acidity constants, etc. Zeta potential as a new approach other than the acidic-alkalimetric titration method was adopted for simulation of adsorption phenomena. Some fitting parameters were determined by the trial and error method. Modeling approach was successful in quantitatively simulating adsorption behavior under various geochemical conditions.
