예병호(Byung-Ho Yae),김해숙(Hae-Sook Kim),김우영(Woo-Young Kim),이성창(Sung-Chang Lee) 한국정보과학회 2000 정보과학회논문지 : 정보통신 Vol.27 No.3
본 논문은 무선 ATM 서비스의 핸드오버 처리를 위한 경로 재구성 방법에 대한 것으로써 경로 재구성을 위한 교차 스위치의 신속한 검색을 위하여 경로 연혁정보를 활용하는 방법을 제안하였다. 본 방법에서는 단말로부터 핸드오버가 요구되는 시점에서 현재의 연결에 대한 경로정보를 전달 받아 경로 연혁정보에서 일치되는 교차 스위치를 찾아 직접 경로 재구성을 위한 신호정보를 전달함으로써 경로 재구성 처리시간을 단축시킬 수 있다. 그리고 핸드오버 과정에서의 셀 순서 유지와 유실을 방지하기 위하여 기지국에서 관리하는 버퍼 사용방법을 사용하였다. A history-based path rerouting scheme is proposed to support fast crossover switch discovery and reduce handover processing time for the wireless ATM services. In this scheme, we can reduce crossover switch searching time by using already established connection path information kept in base station for the call duration. The old path information is compared to the current connection path information to find matched crossover switch. Also we use efficient buffering in base station to conserve cell sequence and avoid cell losses.

A Cymbidium variety 'Snow Bell' (C. kanran ${\times}$ C. Jack Frost) was developed at the National Institute of Horticultural & Herbal Science, Rural Development Administration in 2011. A cross between C. kanran with small-sized greenish colored flowers and C. Jack Frost with bright pink colored flowers, was conducted in 1999. Based on flower color, leaf shape, flower stalk, and vigor one line was selected. Evaluation and selection trials were conducted from 2006 to 2010. 'Snow Bell' has a light pink sepal (RHS, R56D), red lip (R56A) and a leaf length of 47.5 cm. The average number of flowers on each peduncle is 13.8 and the flower diameter is 6.2 cm. The characteristics of petals and sepals show some incurve and some spreading. 'Snow Bell' has a vigorous growth and a round flower. It has an adequate peduncle height of 50.7 cm compared with leaf length of 47.5 cm, and start blooming in December. In electronic nose analysis, the degree of fragrance between 'Snow Bell' and the C. kanran was similar and both of them showed strong scents, although they had different fragrance patterns.
