Wavelet transform and its inverse processing provide the effective framework for data fusion. The purpose of this study is to investigate applicability of wavelet transform using texture images for the urban remote sensing application. We tried several experiments regarding image fusion by wavelet transform and texture imaging using high resolution images such as IKONOS and KOMPSAT EOC. As for texture images, we used homogeneity and ASM (Angular Second Moment) images according that these two types of texture images reveal detailed information of complex features of urban environment well. To find out the useful combination scheme for further applications, we performed DWT(Discrete Wavelet Transform) and IDWT(Inverse Discrete Wavelet Transform) using texture images and original images, with adding edge information on the fused images to display texture-wavelet information within edge boundaries. The edge images were obtained by the LoG (Laplacian of Gaussian) processing of original image. As the qualitative result by the visual interpretation of these experiments, the resultant image by each fusion scheme will be utilized to extract unique details of surface characterization on urban features around edge boundaries.

The purpose of this study was to development of the 'convergence motive' scale for interdisciplinary knowledge fusion. Based on results from literature review, this study clarifies a theoretical ground for 'convergence motive'. Initial items to measure this concept were verified by content analysis and then finalized. After a pilot test done with 568 college students, gathered data were analyzed by item selection and exploratory factor analysis to verify their validity. Next, the main test implemented with 1,211 college students was analyzed with exploratory factor analysis using the method for rotation based on maximum likelihood analysis and direct oblimin for validating the final items to measure 'convergence motive'. As a result, the scale for 'convergence motive' consists of 43 items to measure the following four factors: collaboration to identifying and solving problems, challenge of a new perspective, communication for convergence, cohesion for convergence. Construct validity and criterion-related validity were performed at last to check this scale's theoretical construct. In conclusion, this study concluded that the scales for convergence motive could be generalized and applicable to other samples.

Hagfish which belongs to the chordate contact cyclostomata, is important phylogenetic relationship between vertebrate and invertebrate. Cathepsins of the cysteine protease family have traditionally been thought to play a major role in intracellular protein degradation and turnover in lysosomes. In this study, Catepsin L was cloned from Inshore hagfish (Eptatretus burgeri), the cDNA encoding ORF of the Eptatretus burgeri Cathepsin L (EbCtL) is 978 bp. The cDNA encoding proEbCtL was expressed in Escherichia coli strain BL21(DE3) using the pGEX-4T-1 expression vector system. The recombinant proEbCtL protein was overexpressed as a approximately 55 kDa fusion protein. The overproduced soluble GST-fusion protein was then applied to glutathione-Sepharose 4B column chromatography; the sample harboring the fusion protein evidenced a high degree of purity when analyzed via SDS-PAGE and Western blot analysis. Its activity was quantied by cleaving the synthetic peptide Z-FR-AMC, Z-LLE-AMC, and Suc-AAF-AMC, and the optimal pH for the protease activity was 8, 9.5, and 9, respectively.
