천연색소에 의한 생화의 염색가능성을 조사하기 위해 치자황색소로부터 생물변환 된 청색소의 특성과 나팔나리 ‘죠지아’와 숙근안개초 ‘브리스톨 페어리’ 꽃에 대한 치자 청색소의 염색성을 조사하였다. 치자 황색소에 Streptococcus mutans 균주를 72시간 배양시킨 결과 Hunter b*값은 1이하, pH는 5.5, 색가는 10.9를 나타냈으며, 흡광도는 588㎚에서 흡수극대를 나타내어 청색소로 변환된 것이 확인되었다. 나팔나리와 숙근안개초는 치자 청색소 희석용액 1.0%액에서는 48시간, 2.0% 및 4.0%액에서는 24시간 이상 꽂아두었을때 꽃잎이 청색으로 염색되었다. 치자청색소를 흡수시킨 나팔나리 절화 수명은 4.0% 희석 용액을 24시간 흡수시킨 것만이 1~2일 정도 단축되었다. This study was conducted to examine the characteristics of blue pigment bioconversed from the yellow pigment of common gardenia (Gardenia jasminoides for. grandiflora), and its dyeing with Lilium longiflorum cv. Georgia and Gypsophila paniculata. cv. Bristol Fairy. Hunter b* value, pH, and color value for the yellow pigment of Gardenia jasminoides as affected by the incubation of Streptococcus mutans for seventy two hours were below 1, 5.5, and 10.9. Maximum absorbance of that at 588 nm was obtained immediately after the incubation of strains. And it was also confirmed that yellow pigment was bioconversed into blue pigment. Petals of trumpet lily and baby’s breath were completely dyed blue when those were immersed in 1.0% diluted solution for forty eight hours, and 2.0% and 4.0% for twenty four hours dipping in the solution of common gardenia blue pigment. Vase life of trumpet lily immersed in 4.0% diluted solution of common gardenia blue pigment for twenty four hours was only shortened by one to two days.

This study was conducted to investigate into the kinds and characteristics of main plant materials for press flower which was marketed in Korea. Special shops for press flower were surveyed twice from August, 2005 to April, 2006. Plant materials for press flower were thirty seven woody materials, and one hundred and eleven herbaceous materials. The region of woody materials used were in the order of flowers (53.3%), leaves (37.8%), the others (20.0%), and stems (17.8%). And that of herbaceous materials were in the order of flowers (68.6%), stems (52.9%), leaves (33.9%), and the others (14.0%). The main standard length of plant materials were 5 to 8㎝, and those width were below 3.1㎝. Over ninety five percentage of woody and herbaceous materials were produced in Korea. Various colors were shown in the plant materials of press flower in Korea, however, white woody and green herbaceous materials were surveyed significantly in this study. Woody and herbaceous materials which were dyed were shown by 34% and 23%. Over 50% of woody and herbaceous materials were discolored and sold well.

Urban railway can be divided into ground and underground sections. In particular, the center of the metropolitan has been built mostly underground stations and tunnels. Underground section is difficult to measure the position because GPS signal is unavailable, so it is necessary to apply the indoor positioning technology. For this purpose, we analyzed the positioning technologies which are based on Wi-Fi and mobile base stations. The positing technology for smart phone which uses mobile base station’ information is developed in the underground area of urban railway where the core technique is to implement base station ID into the positing technology by considering hand-off point. 도시철도는 지상과 지하 구간으로 분류할 수 있으며, 특히 수도권 중심부는 대부분이 지하 역사 및 터널로 구축되어 있다. 지하 구간은 지상과 달리 GPS 수신이 불가능하여 위치 측정이 힘들기 때문에 실내 측위 기술적용이 필요하다. 이를 위하여 본 연구에서는 Wi-Fi 기반과 이동통신 기지국 기반의 측위 기술에 대하여 분석하였다. 특히 도시철도 지하구간에는 핸드폰 통신을 위한 이동통신 기지국 정보를 활용한 기술을 연구하였으며, 핵심적인 기술로 터널 구간에서의 Hand-off 지점 간 변화되는 기지국 ID정보를 측위 기술에 적용하는 방안을 연구하였다.
