Due to the lack of judgement in an information processing on road sign, older drivers usually are having a hard time driving than young group. Furthermore, according to increasing in aging population, older drivers in Korea have been growing much faster. That means research for older drivers' characteristics and the number of guide name for road sign should be needed. In accordance with suggestions, this study was carried out the number of guide names for road sign with a variety of ages from the twenties to the seventies. For the sake of this study, statistical verification was conducted to confirm a change of speed, a reading time and a misreading rate with Driving Simulator and Electrooculogram tool. As the results of study, change of speed in the age range has shown that the higher the proportion of age, the lower the rate of velocity. Also reading time in the age range with regression analysis found that the higher the proportion of age, the higher the rate of reading time by 0.106sec. Finally, a binary logistic model was used to find the main factors. As the results, 4 number of guide names for road sign have been the best of them for older driver. The result of this study verified the importance of ideal guide numbers on road sign for older driver and proved itself to be an effective method to determine the road safety for the road signs.

The purpose of this study is to determine the economical standard for road signs by verifying the difference in driver's legibility time with respect to the spacing of letters on the toad signs. Laboratory simulations were conducted to confirm the difference in legibility time for six target signs of different spacing. Also. a binary logit model was used to find the main factors, which could lower the rate if misreading. This model involves not only a simple enlargement of signs but also a suitable match of letters and signs along with the optimal spacing of the text letters on the road signs to increase the legibility of the sign. The result of this study verified the importance of spacing in road signs and Proved itself to be an effective method to determine the future standard for the road signs.

본 연구에서는 사람이 한글을 읽는 동안에 문자인식에 영향을 미치는 문장구조의 여러 요소 중 글자크기와 줄간간격에 대한 주시시간과 오독률을 분석함으로써 한글 인식에 있어서 사람에게 적합한 문장구조를 제시하는 데 그 목적이 있다고 할 수 있다. 실험에서는 남녀 각 5명씩의 피실험자에게 아이카메라를 착용시킨 후, 40cm 거리에서 문장중심과 피실험자의 시선이 일치되게 하여, 각기 다른 문장구조를 가 지는 9개의 실험예문(B5용지)을 소리내어 읽게 하였다. 실험결과로 부터 글자크기 와 줄간간격은 읽기수행도(reading performance)에 영향을 미치는 것으로 나타났다. 이를 이용하여 인쇄물의 제작시에 적용시켜 읽기수행도를 제고시킬 수 있다.

본 논문은 인식된 컨테이너 식별자 문자열과 컨테이너 작업리스트를 비교하여 작업리스트와 인식된 컨테이너 식별자 문자열을 매칭하는 효율적인 방법을 소개하고자 한다. Dynamic Time Warping 기법을 이용하여 오인식되거나 인식이 되지 않은 문자에 대하여 오독률을 최소화할 수 있는 효율적인 방법을 제안한다. 기존의 문자열 비교방식에 비하여 제안하는 방법을 사용하였을 경우 더 나은 성능을 보였다.
