This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern and marker orientation using woman's Jacket and Slacks. Research Method intended to compare the marking efficiency of Jacket and Slacks, check-less and check- patterned materials with the intervals of 1.5×1.5cm and 5×5cm were selected. First, in the comparison of marking efficiency depending on check-pattern interval, regardless of the direction of marker position, single-item makers and set-item makers, the efficiency of check-less materials was higher than those of check-patterned materials and increasing the intervals decreased marking efficiency and vice versa. Marking efficiency of Slacks was less influenced than marking efficiency of Jacket by check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and number of maker pieces, the efficiency of nap-up-and-down position was higher than those of nap-one-way position. Third, the marking efficiency of single-item was more effective than one of set-item in all working condition except nap-one-way position in checkless materials.

많은 수의 기존구조물의 내진보강 여부를 효율적으로 판단하기 위해서는 다단계로 구성되는 평가시스템을 도입하는 것이 바람직하다 본 연구에서는 지진피해를 입은 입체라멘 구조물의 피해원인을 지반 및 구조물의 특성에 따라 조사 검토하였으며 부재의 전단-휨 강도 여유도가 구조물의 내진성능에 밀접한 관계가 있음을 보여주고 있다 전단-휨 강도여유를 이용하여 대상구조물의 내진성능보강여부를 1차적으로 평가할 수 있는 1차 평각법을 제시하였으며 그 유효성을 구조물의 패해도와 비교하여 확인하였다.
