The tower cranes are widely used in very useful construction machine the sites of constructing high-structure and have a structural sensitiveness. Therefore, the accidents have often happened due to the deficiency of laborer's understanding md lack of safety of structure. Till now, as we have research and studied above, we can properly protect accidents by construction equipments particularly crane as well as most disasters which occur frequently in construction site. The goal of this study is the safety inspection model of the tower crane a construction site, which preventible the collapse accident of tower crane which is constructed by using the correcting frame. In order to accomplish the goal of this study, the field survey, the reference investigation and the structure analysis were performed for the collapse accident of tower nine using the correcting data. This study will be proposed a build-up solutions about operating and release of safety constructions and researched about software safety estimation. Also, preventing safety problems of Tower Crane Construction site as applying safety estimation program and laws and regulations. As a result, The real time control of tower crane inspection system is implemented by to illustrate the application of the adopted optimal design model.

목적 : 문항반응이론에 기초한 Rasch모형을 적용하여 뇌졸중 입원환자의 일상생활수행 평가도구를 개발하는 것이다． 연구방법 : 2002년 8월 5일부터 2005년 4월 20일까지 전국 18개 재활기관에서 뇌졸중 입원환자 308명을 대상으로，작업치료사가 평가한 6개 영역의 23개 항목으로 구성된 설문지 결과를 수집하여 Winsteps 프로그램으로 라쉬분석하였다． 결과 : 3개 항목이 부적합한 항목으로 판정되었으며，남은 20개 항목의 난이도 순서를 배열하였다．뇌졸중 입원환자의 일상생활 수행능력은 -6.77~6.73 로짓으로 표시할 수 있으며，표준화점수로 표시하기 위한 변환식은 "점수 =（로짓점＋6.77)/ (6.77+6.73) 100" 이었다．평가항목의 난이도는 가장 어려운 항목은 보행영역의 ‘계단 오르내리기’ 항목이었으며，가장 쉬운 항목은 식사하기 영역의 ‘음료 마시기’ 항목 이었다． 결론 : 라쉬분석을 이용한 뇌졸중 입원환자의 일상생활수행 항목의 적합도와 난이도에 관한 결과제시로 개발되었으며，신뢰도와 타당도가 입증된 객관적인 평가도구이다．
