  • In this paper, we proposed a robust watermark scheme for image based on the discrete wavelet transform. In the first, we use the triplet method for embedding and extraction of watermark. Triplet method uses relationship among the discrete wavelet coefficients at the same position in the three detail subband of image. In the second, we use barcode Pattern Image for watermark scheme. By using barcode Pattern Images, a user is able to make many kinds of own watermark. In the third, the proposed method for image watermark provides the invisiblility which the other user can not discriminate watermark from watermarked image. The advantage of the proposed method is visibility when we extracted watermark from the image. The corresponding experimental results show that the proposed method has performance of a robustness from the noise attack.

  • In this paper, we proposed a robust watermark scheme for image based on SVD(Singular Value Transform) and Triplet. First, the original image is decomposed by using 3-level DWT, and then used the singular values changed for embedding and extracting of the watermark sequence in LL3 band. Since the matrix of singular values is not easily altered with various signal processing noises, the embedded watermark sequence has the ability to withstand various signal processing noise attacks. Nevertheless, this method does not guarantee geometric transformation(such as rotation, cropping, etc.) because the geometric transformation changes the matrix size. In this case, the watermark sequence cannot be extracted. To compensate for the above weaknesses, a method which uses the triplet for embedding a barcode image watermark in the middle of frequency band is proposed. In order to generate the barcode image watermark, the pattern of the watermark sequence embedded in a LL3 band is used. According to this method, the watermark information can be extracted from attacked images.

  • We determined the cytochrome c oxidase subunit 1 (CO1) sequences of Nebalia koreana Song, Moreira & Min, 2012 (Leptostraca) collected from five locations in South Korea, and this represents the first genetic data of this species. The maximum intra-species variation was 1.2% within Nebalia hessleri Martin, Vetter & Cash-Clark, 1996, while inter-species variation ranged from 9.0% (N. hessleri and Nebalia gerkenae Haney & Martin, 2000) to 34.8% (N. hessleri and Nebalia pseudotroncosoi Song, Moreira & Min, 2013). This result is well agreed with the interspecific relationships among Nebalia species based on morphological characteristics. In conclusion, this study showed the usefulness of CO1 sequences as a DNA barcode within the genus Nebalia Leach, 1814.

  • A eunicid polychaete, Marphysa victori Lavesque, Daffe, Bonifácio & Hutchings, 2017 is described for the first time from the intertidal zones of the Korean coasts. It is characterized by having three types of pectinate chaetae (INS, isodont-narrow-slender; AWS, anodont-wide-slender; and AWT, anodont-wide-thick), appearance of pectinate chaetae from chaetiger 2, the chaetae consisted of pectinate and compound spinigers, and pygidium with one pair of pygidial cirri. In genetic analysis based on cytochrome c oxidase subunit I (COI), intra-specific genetic distance between the specimens of M. victori from its type locality, France and Korea are in the range of 0.000-0.013. This paper includes the morphological description and photographs of M. victori new to Korean fauna, with partial sequences of the mitochondrial COI as DNA barcode data on this species.

  • Objectives : Due to the morphological similarity of the pericarp and description of multi-species in National Pharmacopoeia of Korea and China, the Zanthoxylum Pericarpium is difficult to authenticate adulterant in species levels. Therefore, we introduced the sequence analysis of DNA barcode and identification of single nucleotide polymorphism(SNP) to establish a reliable tool for the distinction of Zanthoxylum Pericarpium from its adulterants. Methods : To analyze DNA barcode region, genomic DNA was extracted from twenty-four specimens of authentic Zanthoxylum species and inauthentic adulterant and the individual internal transcribed spacer regions (rDNA-ITS and ITS2) of nuclear ribosomal RNA gene were amplified using ITS1, ITS2-S2F, and ITS4 primer. For identification of species-specific sequences, a comparative analysis was performed using entire DNA barcode sequences. Results : In comparison of four Zanthoxylum ITS2 sequences, we identified 16, 4, 6, and 4 distinct species-specific nucleotides enough to distinguish Z. schinifolium, Z. bungeanum, Z. piperitum, and Z. simulans, respectively. The sequence differences were available genetic marker to discriminate four species. Futhermore, phylogenetic relationship revealed a clear classification between different Zanthoxylum species showing 4 different clusters. These results indicated that comparative analysis of ITS2 DNA barcode was an useful genetic marker to authenticate Zanthoxylum Pericarpium in species levels. Conclusions : The marker nucleotides, enough to distinguish Z. schinifolium, Z. piperitum, Z. bungeanum, and Z. simulans, were obtained at 30 SNP marker nucleotides from ITS2 sequences. These differences could be used to authenticate official Zanthoxylum Pericarpium from its adulterants as well as discriminating each four species.

  • Most Araliaceae plant species distributed in Korea are economically important because of their high medicinal values. This study was conducted to develop barcode markers from sequence analysis of chloroplast DNA in 14 taxa of Araliaceae species grown in South Korea. Sequencing of seven chloroplast DNA regions was performed to establish the DNA barcode markers, as suggested by the Consortium for the Barcode of Life (CBOL). From the sequence analysis of chloroplast DNA, we identified specific sequences and nucleotides that allowed us to discriminate among each other 14 Korean Araliaceae species. The sequence in the region of psbA-trnH revealed the most frequent DNA indels and substitutions of all 7 regions studied. This psbA-trnH marker alone can discriminate among all 14 species. There are no differences between Korean and Chinese Panax ginseng in all seven sequenced chloroplast DNA regions. A phylogenetic tree constructed using the seven chloroplast DNA regions revealed that Tetrapanax papyriferus should be classified as an independent clade. The Aralia and Panax genera showed a close phylogenetic relationship. Five species in the Eleutherococcus genus were more closely related to Kalopanax septemlobus than to any Panax species.
