본 연구는 청년 발달장애인과 중고령 발달장애인의 자립과 삶의 만족도 차이, 그리고 이들 간의 인과관계를 규명하기 위해 2022년 ‘발달장애인 일과 삶 실태조사’ 데이터를 활용하였다. 만 19세 이상 성인 2,518명이 추출되었고, 청년 발달장애인 1,681명 중고령 발달장애인 827명이 포함되었다. 분석결과는 다음과 같다. 첫째, 독립집단 t검정 결과 청년 발달장애인 집단은 중고령 발달장애인 집단보다 삶의 만족도, 자립의 구성요인인 인지능력, 자기결정능력, 사회참여 수준이 높은 것으로 나타났다. 둘째, 집단별 삶의 만족에 자립의 어떤 요인이 영향을 미치는지 회귀분석을 실시한 결과 청년 발달장애인의 삶의 만족도에는 일상생활수행능력, 자기결정능력, 언어이해능력, 사회참여가, 중고령 발달장애인의 삶의 만족도에는 자기결정능력과 사회참여가 영향을 미치는 것으로 나타났다. 즉 집단별 삶의 만족도에 영향을 미치는 자립의 요인은 동일하지 않았다. 이에 대한 함의가 결론에 제시되었다. This study aimed to investigate differences in independence and life satisfaction between young adults with developmental disabilities and middle-aged and older adults with developmental disabilities, and the causation between them by using data from the 2022 ‘Survey on the Work & Life of Persons with Developmentally Disabilities’. A total of 2,518 adults aged 19 years and older were extracted, including 1,681 young adults with developmental disabilities and 827 middle-aged and older adults with developmental disabilities. The results are following. It was, first, found that the group of young people with developmental disabilities had a higher level of life satisfaction, cognitive ability, self-determination, and social participation, which are the components of independence than those of older people with developmental disabilities. Second, activities of daily living, self-determination, language comprehension, and social participation were significant indicators of life satisfaction of young people with developmental disabilities, and the life satisfaction of middle-aged and elderly people with developmental disabilities was affected by self- determination and social participation. Therefore, the factors of independence influencing life satisfaction in each group were not the same. The implications of these results were presented in the conclusion.

We present a power-efficient driving scheme that consists of piezoelectric actuator and driver IC for AF (Auto-Focus) on ISM (Image Sensor Module). The piezoelectric actuator is more power-efficient than conventional voice coil motor actuator. And high power-efficiency driver IC is designed. So the proposed driving scheme using designed piezoelectric actuator and driver IC is more close to recent trend of green IT. The diver IC should guarantee fast and accurate performance. So, the optimum driving method and high accurate frequency synthesizer are proposed. The die area of designed driver IC is $2.0{\times}1.6mm^2$ and power consumption is 2.8mW.
