Eun-Young Lee 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 14 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2011, Vol.5 No.2 5 93-106 (14 pages)
The purpose of this study was to investigate the mathematical experience while children roleplay in a spaceship and a fruit-store. The subjects were the children involved in the roleplaying area during their free-choice activity period. The kindergarten was located in Seoul, Korea and the class consisted of 15 five-year-olds. Data was collected three times a week for four weeks. Role-playing happened during the free-choice activity and it took about 50-60 minutes each time. I collected the data... -

Malva vein clearing virus (MVCV) is a member of the Potyvirus species, and has a negative impact on the aesthetic development of Alcea rosea. It was first reported in Germany in 1957, but its complete genome sequence data are still scarce. In the present work, A. rosea leaves with vein-clearing and mosaic symptoms were sampled and analyzed with small RNA deep sequencing. By denovo assembly the raw sequences of virus-derived small interfering RNAs (vsiRs) and whole genome amplification of malva... -
siRNAs Derived from Cymbidium Mosaic Virus and Odontoglossum Ringspot Virus Down-modulated the Expression Levels of Endogenous Genes in Phalaenopsis equestris

Interplay between Cymbidium mosaic virus (CymMV)/ Odontoglossum ringspot virus (ORSV) and its host plant Phalaenopsis equestris remain largely unknown, which led to deficiency of effective measures to control disease of P. equestris caused by infecting viruses. In this study, for the first time, we characterized viral small interfering RNAs (vsiRNAs) profiles in P. equestris co-infected with CymMV and ORSV through small RNA sequencing technology. CymMV and ORSV small interfering RNAs (siRNAs)... -
통계적 영상처리를 이용한 과일 선별시스템 개발
한국통계학회 응용통계연구 2003, Vol.16 No.1 129-140 (12 pages)
본 논문은 통계적 영상처리를 이용하여 과일 선별 시스템을 개발하고자 한다. 히스토그램으로부터 과일 영상의 색깔에 대한 분포를 파악하고 이 표본 위치문제에서 Wilcoxon 검정을 이용하여 에지를 검출한다. 체인코드로부터 과일 영상의 면적, 둘레, 장ㆍ단축의 길이와 원형도 등 기하학적 특성값을 얻는다. 우리는 과일에 대한 영상실험을 통하여 통계적 에지검출 방법에 토대를 둔 시스템과 기존의 Sobel 연산자에 토대를 둔 시스템과의 비교 분석한다.
