Abstract

Necessity of adjustment in level of difficulty of national examination for radiological technologists is being brought up. However, objective reasons are required to make those arguments more valid. Therefore in this research, result of national examination for radiological technologists under present system was analyzed in more convergence perspective via statistical analysis. This will provide basic data which is applicable when system of national examination for radiological technologists undergo improvements. For this, statistical analysis such as descriptive statistics and correlation analysis was conducted using SPSS program. Results are as follow. First, ratio of successful applicants for radiological technologists was highly fluctuant relative to other national examinations like doctor, nurse, physical therapist, etc. Second, level of difficulty and discernment of national examination for radiological technologists were differentiated from other examinations like doctor, nurse, physical therapist. Third, the 43th examination for radiological technologists conducted in 2015 had the highest discernment as 0.41, despite of lowest level of difficulty as 89.2, for radiologic applications. The results of this research is expected to be used as basic data when system of national examination for radiological technologists undergo improvements, in accordance with increased supplying plan of work-forces in medical radiological technologists.

방사선사 국가시험에 대한 난이도 조정의 필요성 등이 제기되고 있다. 이러한 주장들이 타당성을 갖기 위해서는 객관적인 근거가 요구된다. 이에 본 연구는 현행 제도 하에서 실시된 방사선사 국가시험 결과를 통계분석을 통하여 융합적인 관점에서 분석하였다. 이는 향후 방사선사 국가시험제도 개선 시 활용 가능한 기초자료를 제공하고자 함이다. 이를 위하여 SPSS 통계분석 프로그램을 이용하여 기술통계 및 상관분석 등의 통계분석을 실시하였다. 그 결과 다음을 알 수 있었다. 첫째, 방사선사 국가시험은 의사, 간호사, 물리치료사 등의 국가시험에 비하여 합격률의 변동이 매우 심했다. 둘째, 방사선사 국가시험의 전체 문항에 대한 난이도와 분별도는 의사, 간호사, 물리치료사 등의 다른 시험에 비하여 차별화됨을 알 수 있었다. 셋째, 2015년도 치러진 제43회 방사선사 시험의 경우 방사선응용은 난이도가 79.2점으로 가장 쉬움에도 불구하고 변별도는 0.41로 가장 높았다. 본 연구의 결과는 향후 방사선사 의료 인력의 수급계획에 맞추어 방사선사 시험제도가 개선될 때 기초자료로서 활용될 것으로 기대해 본다.
