Abstract

The fundamental concerns of this paper are to analyze the effects of some characteristics on the employment of new college graduated students in viewpoint of data visualization. We use individual and department characteristic data of K-university graduated students in 2010. We apply multiple correspondence analysis, decision tree analysis, association rules and social network analysis for data visualization. The results of the analysis are summarized as follows. First, an analysis of the determinants of employment shows that GPA, department category, age and number of majors, recruiting time affect the employment rate. Second, higher GPA and natural category of department positively affect the employment rate. Finally, low age, single major and early recruiting time also positively affect the employment rate.

대졸 취업자들의 특성을 분석하기 위해 주로 모수적인 접근방법을 사용해 온 기존의 연구와는 달리, 본 연구에서는 R 프로그램을 이용하여 데이터 시각화에 초점을 맞추어 분석하였다. 이를 위해 취업여부에 미치는 개인특성 변수들의 유사성 분석을 위해 다중대응분석을 실시하였다. 또한 취업여부에 영향을 미치는 개인특성 변수들의 고차 상호작용효과를 분석하기 위해 의사결정나무분석을 실시하였다. 그리고 연관성분석을 이용한 연관성 규칙을 계산하여 개인특성 변수들이 취업여부에 미치는 효과를 분석하고, 연관성규칙의 결과를 사회연결망분석의 연결망 구조로 시각화 하였다. 분석결과 다음과 같은 주요 결과를 얻었다. 첫째, 취업여부에 영향을 미치는 변수들로는 평균평점, 계열, 강의평가 점수, 성별 등으로 나타났다. 둘째, 평균평점과 강의평가점수가 보통이상으로 높고 자연계열인 경우 취업 가능성이 높음을 알 수 있다. 또한 수시모집으로 입학한 연령이 낮은 졸업생이 취업가능성이 높게 나타났다. 셋째, 평균평점이 낮고 예체능 계열이며 연령이 높은 대졸자들이 취업가능성이 낮음을 알 수 있다. 또한 예체능 계열의 단일전공을 한 여학생들의 경우도 취업가능성이 높지 않음을 알 수 있다.
