원추리속은 백합과에 속하고 약 30종으로 구성된 원예학적으로 중요한 속이며 동북아시아 특산이다. 19종류의 형태학적 개화학적인 형질을 대상으로 주성분 분석 결과 4종의 한반도 자생 원추리가 인지되고 있다; 백운산원추리(=함양원추리, 중부, 남부지방 및 한반도 북서 지방에 자생) ; 노랑원추리(=H. coreana는 한반도 남서지방 및 중부지방에 자생) ; 들원추리 (한반도 북동부 및 중부 고산지대 자생) ; 홍도원추리(홍도, 대흑산도 및 소흑산도에 자생), 각 종에 대한 형태학 및 생물학적 특질이 본 논문에 기재되고 있으며 앞으로 경제적으로 유용한 원예품종을 작출하기 위해서 형질의 원예학적 유용성에 대해서 제시하고 있다. Hemerocallis L. (Liliaceae) is an horticulturally important genus of approximately 30 species of herbaceous perennial restricted to East Asia. Based on the principal components analyses using 19 morphological and phenological traits in this study, four Korean species have been recognized : H hakuunensis Nakai (=H. micrantha Nakai, growing on the southern, cental, and northwestern Korea) ; H. thunbergii Baker (=H. coreana Nakai, found on the southwestern and central Korea) ; H. middendorffii Tr. et Mey. (the central and northeastern Korea) ; and H. hongdoensis M. Chung & S. Kang (Hong. Taehuksan, and Sohuksan Islands). The morphological and ecological traits for each species and the horticultural usefulness of these characters to produce economically important cultivars are described.

In this paper, we presents a new disparity map refinement algorithm using statistical characteristics of disparity map and Edge information. The proposed algorithm generate a refined disparity map using disparity maps which are obtained from area and feature-based stereo matching by selecting a disparity value of edge point based on the statistics of both disparity maps. Experimental results on aerial stereo image show the better results than conventional fusion algorithms in the disparity error. This algorithm can be applied to the reconstruction of building image from the high resolution remote sensing data.

<P><B>Abstract</B></P> <P>If a multi-component monosugar mixture including fucose was used as the substrates for the <I>Klebsiella oxytoca</I> fermentation, it could offer the following two benefits simultaneously; (i) the removal of all monosugars other than fucose, and (ii) the acquisition of 2,3-butanediol (BD). To utilize such two benefits in favor of the economical efficiency of the fucose production process, it is essential to accomplish a high-purity separation between fucose and BD on the basis of a highly-economical mode. To address this issue, we aimed to develop a simulated moving bed (SMB) process for continuous-mode separation of fucose and BD with high purities. It was first found that an Amberchrom-CG71C resin could become a suitable adsorbent for the separation of interest. The intrinsic parameters of fucose and BD on such proven adsorbent were determined, and then applied to the optimal design of the fucose-BD separation SMB. The capability of the designed SMB in ensuring high purities and high yields was experimentally verified. Finally, we devised two potential strategies to make a further improvement in product concentrations and/or desorbent usage while keeping the purities and yields of fucose and BD almost unchanged. The first strategy was based on partial extract-collection and partial extract-discard, which was found to result in 33% higher BD product concentration. The second strategy was based on partial extract-collection, partial extract-recycle, and partial desorbent-port closing, which could lead to 25% lower desorbent usage, 33% higher BD product concentration, and 7% higher fucose product concentration.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We developed the SMB for continuous separation of fucose and 2,3-butanediol (BD). </LI> <LI> Intrinsic parameters of fucose and BD on Ambercrhom-CG71C adsorbent were determined. </LI> <LI> They were used to optimize the SMB and its performances were verified experimentally. </LI> <LI> The SMB performances were improved further by using the following strategies. </LI> <LI> Partial collection and partial recycle of extract with partial desorbent-port closing. </LI> </UL> </P>
