The first purpose of this study is the verification of hypothesis on Abies holophylla planted as a guardian for Japanese. Second, the purpose of this study is on Abies holophylla planted in the historic sites for anti-Japan fighter. Japan planted Abies holophylla to honor the god of Suwataisha that took care of the Jingu-Kogo's Conquest of Samhan(Three Kingdoms). The fact that Abies holophylla was planted in the historic sites for anti-Japan fighter such as General Gwon Yul, Yi Sun-Shin was investigated. The hypothesis that Abies holophylla was planted as a guardian for Japanese was verified through survey on the pictures of Abies holophylla in Japanese temple, public sites, company of nursing the saplings, commemorative tree of governor and the judgment of Abies holophylla damage incident. Further studies should focus on the intention of planting Abies holophylla by Japan. Researcher should discuss Abies holophylla planted in the historic sites for anti-Japan fighter because old big trees will be respected.

As sustainability of fashion brands is becoming more important in the prolonged depression, the fashion market is also seeking ways to create new value through convergence with various fields. In the fashion market, convergence marketing is engaged with diverse technologies combined with advanced technologies and strategies. This study established the conceptual characteristics of convergence and divergence from a market perspective. Convergence can be summarized as Borderless, Compounding, Diversification, Recombination and Affiliation. The conceptual characteristics of the divergence can be summarized as de-fusion, individualization, differentiation, specialization, and segmentation. The characteristics of convergence revealed through the case of fashion market include the expandability of the new category, the expandability of the consumer, the brand experience, and the expandability of time and space. Divergence is the differentiation of brand value, target customer, and product nature. Through this study, we could understand the differentiation of the fashion market and the direction of the marketing strategy by looking at the characteristic of the convergence marketing - oriented research that has the contrary conceptual characteristics from the extended viewpoint. Based on this, it is possible to see the changes and patterns of brand marketing strategies and techniques in recent fashion market. In the future, it is expected that the systematic study of the marketing strategy of the domestic fashion brand based on the convergence and change characteristics of the fashion market proposed in this study will continue.

Described in this paper is a design of hardware accelerator for implementing public-key cryptographic protocols (PKCPs) based on Elliptic Curve Cryptography (ECC) and RSA. It supports five elliptic curves (ECs) over GF(p) and three key lengths of RSA that are defined by NIST standard. It was designed to support four point operations over ECs and six modular arithmetic operations, making it suitable for hardware implementation of ECC- and RSA-based PKCPs. In order to achieve small-area implementation, a finite field arithmetic circuit was designed with 32-bit data-path, and it adopted word-based Montgomery multiplication algorithm, the Jacobian coordinate system for EC point operations, and the Fermat's little theorem for modular multiplicative inverse. The hardware operation was verified with FPGA device by implementing EC-DH key exchange protocol and RSA operations. It occupied 20,800 gate equivalents and 28 kbits of RAM at 50 MHz clock frequency with 180-nm CMOS cell library, and 1,503 slices and 2 BRAMs in Virtex-5 FPGA device.

This study was carried out to investigate a radial distribution of moisture contents(MCs) within a log cross section(LC) during oven-drying of circumferential slices cut from some of domestic hardwoods LCs. For zelkova, the slices from sapwood and from transition part already reached to below hygroscopic range at 30% in average MC, whereas the innermost slice represented about 40% MC. A moisture gradient between the innermost slice and the adjacent slice from a cherry LC became severer with drying times. For castor aralia, the green MC for heartwood slices was approximately 23% higher than that for sapwood slices, and the similar moisture gradient still lasted until average 15% MC during oven-drying. For Chinese mahogany, the MCs of the mixed slices and the innermost slice were lower than those of the slices cut from the other parts during all over drying stage.

The purpose of this study is to determine the aesthetic identity of modern eroticism fashion in which the energy of desire is maximized through the 'jouissance' and 'gaze' of the unconscious theory of Jacques Lacan. The research method derived aesthetic identity after examining jouissance and gaze deeply related to eroticism in Lacan's theory of the unconscious by analyzing data of domestic and foreign monographs and prior research. Case analysis was limited to 2000 S/S to 2022 F/W. Based on prior research, it was analyzed mainly on clothing with eroticism characteristics of 'exposure, close contact, see-through, the conversion of underclothes into outer garments'. Results of the study are as follows. First, eroticism, which can be linked to Lacan's type of 'jouissance' with multiple meanings as the generating point of eroticism, has manifested itself in voyeuristic eroticism, fatale eroticism, masochistic eroticism, surplus eroticism, and sacred eroticism. Second, as eyes of unconscious desire, visual expression characteristics of 'gaze' appeared as anamorphosis, trompe l'oeil, and dépaysement. The identity of eroticism derived from Lacan's jouissance and the perspective of the desire gaze was divided into voyeuristic desire to gaze, fatal desire to gaze, masochistic desire to gaze, surplus desire to gaze, and sacred desire to gaze. Results of this study will expand theoretical horizons of eroticist fashion with a new interpretation of eroticism by combining Lacan's desire as a repressed and alienated subject within the human unconscious with the art that expands it.

The advanced medical information systems usually consist of loosely-coupled interaction of independent systems, such as HIS/RIS and PACS. To support easier information exchange between these systems and between hospitals, and to support new types of medical service such as teleradiology, it becomes essential to integrate separated medical information and allow them to be exchanged and retrieved through internet. This thesis proposes an integrated medical information system using XML. We analyzed HL7 and DICOM standard formats, and designed an integrated XML DTD. We extracted information from HL7 messages and DICOM files and generated XML document instances and XSL stylesheets based on the proposed XML DTD. We implemented the web interface for the integrated medical information system, which supports data sharing, information exchange and retrieval between two different standard formats. The proposed XML-based integrated medical information system will contribute to solve the problems of current medical information systems, by enabling integration of separated medical informations and by allowing data exchange and sharing through internet. The proposed system with XML is more robust than web-based medical information systems developed by using HTML, because XML itself provides more flexibility and extensibility than HTML.

These days, as digital producing technique has been developed, 3D imaging technique is used in high-tech computer and T.V. Also study for 3D producing technique is actively in progress. Moreover, as James Cameron's movie, 'Avatar' released in 2009 was a box office hit, the issue about 3D image came to the fore again. At this point, I decided to study the effect of the visual depth caused by the color correction during the post-production stage. The purpose of this study is to offer information about processing effective images through data about the effect of the visual depth that applies the color correction during the post-production stage. Basically, I supposed that color and contract would have effects on depth of 3D image. As a result, I could find out the changes of visual depth, space perception and sense of depth throughout the experiment. Applying this result,, I produced the 15 minutes of 3D advertisement movie and I found out that the color correction during the post-production stage was very effective for 3D depth. The left image and the right image by beam splitter based rig and parallel rig were used for this study. Also I adjusted the strong contrast by the color correction during the post-production stage after correcting convergence and visual depth during editing. As a result, I could produce images which had strong sense of space and sense of depth.

Endophytic bacterial strains from root tissue of strawberry were screened for their efficacy in growth improvement and control of Phytophthora blight disease of chili pepper plant under greenhouse condition. Plants treated with the strain EP103, identified as Pseudomonas fluorescens, showed growth improvement in terms of fresh weight and root length compared to the untreated control and other endophytic strains. When challenged with Phytophthora capsici, there was significant reduction of disease in EP103 treated plants with an efficacy of 78.7%. There was no direct inhibition of the target pathogen by EP103 when tested under in vitro antibiosis assay. Analysis of differential expression of selected marker genes for induced systemic resistance (ISR) in plants treated with EP103 and challenged with P. capsici showed up-regulation of PR1 and PR10 pathogenesis-related (PR) proteins. PCR analysis showed that EP103 produced secondary metabolites such as pyoluteorin, pyrrolnitrin, hydrogen cyanide and orfamide A. This study indicated the potential of endophytic P. fluorescens strain EP103 as an efficient biocontrol agent against P. capsici in chili pepper plant.

This paper proposes an efficient approach for hardware implementation of moving object detection (MOD) processor using effective Gaussian mixture learning (EGML)-based background subtraction method. Arithmetic units used in background generation were implemented using LUT-based approximation to reduce hardware complexity. Hardware resources used for both background subtraction and Gaussian probability density calculation were shared. The MOD processor was verified by FPGA-in-the-loop simulation using MATLAB/Simulink. The MOD performance was evaluated by using six types of video defined in IEEE CDW-2014 dataset, which resulted the average of recall value of 0.7700, the average of precision value of 0.7170, and the average of F-measure value of 0.7293. The MOD processor was implemented with 882 slices and block RAM of $146{\times}36kbits$ on Virtex5 FPGA, resulting in 60% hardware reduction compared to conventional design based on EGML. It was estimated that the MOD processor could operate with 75 MHz clock, resulting in real-time processing of $800{\times}600$ video with a frame rate of 39 fps.
