Abstract

The purpose of this study was to examine demographic, human capital and service factors affecting employment outcomes of people with hearing impairments. The total of 422 individuals (age from 20 years to 65 years) with hearing impairments were collected from the Panel Survey of Employment for the Disabled from Korea Employment Agency for the Disabled. The dependent variable is employment outcomes. The predictor variables include a set of personal history, human capital and rehabilitation service variables. The chi-squared automatic interaction detector (CHAID) analysis revealed that the status of the national basic livelihood security played a determining role in predicting the employment of people with hearing impairments. Also, it was found that the three factors of the status on the national basic livelihood security, needed help about activities of dailey living, licenses & employment service factors created bigger synergy effect when they inter-complemented one another.

본 연구의 목적은 청각장애인의 취업결정요인을 데이터마이닝 기법을 적용하여 분석 제공함으로서, 장애인의 취업 성공률을 높임과 동시에 직업재활 개입의 효율성을 극대화할 수 있는 방안을 제시하는데 있다. 자료 분석을 위해 2013년 장애인고용패널조사의 제6차년도 자료를 이용하여, 전체 패널 데이터 중 청각장애인이면서 전체연령 20세 이상 65세 미만의 422명을 의사결정나무 기법의 하나인 Exhaustive CHAID 알고리즘을 적용하여 분석하였다. 본 연구를 통해서 얻어진 주요한 사실의 하나는 국민기초생활수급여부, 일상생활 도움필요 여부, 그리고 자격증 고용서비스 요인간의 상호작용(interaction)에 관한 패턴 분석이 청각장애인의 취업 예측에 주요한 역할을 할 수 있다는 것으로, 향후 직업재활 개입의 효과성을 높이기 위해 효과적인 취업결정요인, 즉 높은 학력 수준, 자격증 보유, 높은 일상생활 독립성을 가지고 있는 장애인을 적극적으로 발굴하여 집중적인 재활 서비스를 제공할 필요가 있을 것으로 사료된다.
