To characterize plasmids in Xanthomonu axonopodis pv. glycines, we isolated plasmids pAG1 from the strain AG1 and pXAG81 and PXAG82 from the strain Bra, respectively, and sequenced three plasmids. The size of plasmids, pAG1, pXAG81, and pXAG82 was 15,149-base pairs (bp), 26,727-bp, and 1,496-bp, respectively Fifteen and twenty six possible open reading frames (ORFs) were present in pAG1 and pXAG81, respectively. Only one ORF homologous to a rep gene of Xylella fastidiosa was present in pXAG82. pAG1 contained genes homologous to avrBs3, tnpA, tnpR, repA, htrA, three parA genes, M.XmaI, R.XmaI, and six hypothetical proteins. pXAG81 contained genes homologous to avrBs3, tnpA, tnpR, repA, htrA, two parA genes, pemI, pemK, mobA, mobB, mobC, mobD, mobE, trwB, traF, traH, ISxac2, and eleven hypothetical proteins. Based on DNA sequence analysis, we presume that pXAG81 is a conjugal plasmid. Interestingly, we found 0.5-kb truncated avirulence gene similar to aurXacE3 on the right border of avrBs3 homolgs of pAG1 and pXAG81. Two hundred twenty five isolates were analyzed to find aurBS3 or tra gene homologs by Southern hybridization. The numbers of avrBs3 homolog varied from 3 in AG1 to 8 in AG166. Two hundred seventeen isolates appeared to can conjugative plasmids (pXAG81 type), and thirty eight isolates appeared to carry non-conjugative plamids (pAGl type). This indicated that aurBs3 gene homologs might be spread by conjugation in X. axonopodis pv. glycines.

Within the past decade, TCP/IP network environment has been explosively widespread all over the world. As the internet and the WWW expand their boundaries, the network traffic caused by data transfers over the internet has also increased. In this paper, we present the design and implementation of a WebTraMAS (Web-based Traffic Monitoring and Analysis System) which can resolve the shortcomings of current management approaches, particularly on the network traffic monitoring and analysis. The WebTraMAS presented in this paper performs the network management activities based on the parameters related to the MIB-II of SNMP and the parameters related to the QoS such as network performance and fault. The proposed WebTraMAS, implemented using the WWW technology, is able for the network manager to manage the network easily and platform independently with the performance analysis of internet traffic.

The structural model of midship section is within the scope of STEP AP218. It supports to represent the ship structure, but most of shipyards and classification societies exchange the information using 2D drawings at the present. To translate the 2D information into the ship structure model of STEP AP218, we analyze the 2D midship section information of KR-TRAS of Korean Register of shipping, and include the transverse members information with the 3D model. We also define the mapping table and the mapping relationships between two data structures. With this mapping table we develop the translator for the midship section, and visualize the translated ship structure model using a STEP viewer. The ship structure model can be used to exchange information between design departments, and through the lifecycle of design, analysis, and maintenance.

The quorum sensing (QS) inhibitors that antagonize TraR, a receptor protein for N-3-oxo-octanoyl-L-homoserine lactones (3-oxo-C8-HSL), a QS signal of Agrobacterium tumefaciens were developed. The structural analogues of 3-oxo-C8-HSL were designed by in silico molecular modeling using SYBYL packages, and synthesized by the solid phase organic synthesis (SPOS) method, where the carboxamide bond of 3-oxo-C8-HSL was replaced with a nicotinamide or a sulfonamide bond to make derivatives of N-nicotinyl-L-homoserine lactones or N-sulfonyl-L-homoserine lactones. The in vivo inhibitory activities of these compounds against QS signaling were assayed using reporter systems and compared with the estimated binding energies from the modeling study. This comparison showed fairly good correlation, suggesting that the in silico interpretation of ligand-receptor structures can be a valuable tool for the pre-design of better competitive inhibitors. In addition, these inhibitors also showed anti-biofilm activities against Pseudomonas aeruginosa.

Objective: To assess the diagnostic performance of the Liver Imaging Reporting and Data System (LI-RADS) version 2018 treatment response algorithm (TRA) for the evaluation of hepatocellular carcinoma (HCC) treated with transarterial radioembolization. Materials and Methods: This retrospective study included patients who underwent transarterial radioembolization for HCC followed by hepatic surgery between January 2011 and December 2019. The resected lesions were determined to have either complete (100%) or incomplete (< 100%) necrosis based on histopathology. Three radiologists independently reviewed the CT or MR images of pre- and post-treatment lesions and assigned categories based on the LI-RADS version 2018 and the TRA, respectively. Diagnostic performances of LI-RADS treatment response (LR-TR) viable and nonviable categories were assessed for each reader, using histopathology from hepatic surgeries as a reference standard. Inter-reader agreements were evaluated using Fleiss κ. Results: A total of 27 patients (mean age ± standard deviation, 55.9 ± 9.1 years; 24 male) with 34 lesions (15 with complete necrosis and 19 with incomplete necrosis on histopathology) were included. To predict complete necrosis, the LR-TR nonviable category had a sensitivity of 73.3-80.0% and a specificity of 78.9-89.5%. For predicting incomplete necrosis, the LR-TR viable category had a sensitivity of 73.7-79.0% and a specificity of 93.3-100%. Five (14.7%) of 34 treated lesions were categorized as LR-TR equivocal by consensus, with two of the five lesions demonstrating incomplete necrosis. Interreader agreement for the LR-TR category was 0.81 (95% confidence interval: 0.66-0.96). Conclusion: The LI-RADS version 2018 TRA can be used to predict the histopathologic viability of HCCs treated with transarterial radioembolization.

This paper presents an investigation into cross-cultural transfiguration of Buddhist faith in Goryeo Dynasty, with a focus on $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra that used to be in vogue in East Asia. There are three major types of $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra faith in Goryeo: the first one was concerned about the scripture itself including its citation and publication and the compilation of its annotation books; the second one involved establishing Buddhist rituals related to the scripture; and the final one was to create Dh$\bar{a}$ran$\bar{i}$ stone poles with Dafoding Dh$\bar{a}$ran$\bar{i}$ in Volume 7 of the scripture engraved in stone. While it was the common practice to engrave Zunsheng Dh$\bar{a}$ran$\bar{i}$ in China, the number of stone poles on which Dafoding Dh$\bar{a}$ran$\bar{i}$ was engraved was overwhelmingly large. There are a couple of reasons behind the difference: first, there was a tendency of Zunsheng Dh$\bar{a}$ran$\bar{i}$ being worshiped at the national level in Goryeo, which probably explains why the percentage of Zunsheng Dh$\bar{a}$ran$\bar{i}$ stone poles designed to pray for a personal mass for the dead by engraving Dh$\bar{a}$ran$\bar{i}$ on a stone pole was considerably low. In addition, there were esoteric sects in Goryeo, and it is estimated that they must have got involved in the establishment of Dafoding Dh$\bar{a}$ran$\bar{i}$ stone poles in the former half of Goryeo. Furthermore, the Zen sects had a deep non-Zen understanding of Esoteric Buddhism and tended to practice Dh$\bar{a}$ran$\bar{i}$ in Goryeo. It is estimated that Dafoding Dh$\bar{a}$ran$\bar{i}$ stone poles were set up in large numbers in Goryeo as the prevalence of $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra faith that continued on since the former half of Goryeo was combined with the Zen sects' active position about Dh$\bar{a}$ran$\bar{i}$.

This study seeks to understand the effects of information search activities and brand image on the hotel patronage intention based on the theory of reasoned action. First, it investigates the influence of attitude formed about hotel on the patronage intention. Second, it seeks to develope an alternative to TRA by looking into the effects of hotel image variable on hotel-specific attitude and patronage intention and attempts to substantiate the role of brand image as a substitute to subjective norm to increase the TRA's explanatory power. The main finding of this study are as follow; First, out of the three components of cognitive evaluation of hotel (human service, physical service and information service), human and physicial services were found to have significant influence on patronage intention. Brand image was found to exert notable influence on attitude toward hotel as well as patronage intention. Remarkably, the finding that brand image positively enhanced the TRA model sheds new strategic insight as to the usefulness of brand image as an alternative to overcome the TRA's limitation stemming from subjective norm. Third, it was learned that study subjects gave more weight to external information sources such as TV, radio, newspaper, magazine, and internet than to internal sources such as individual knowledge, experience or self image.

Purpose To evaluate the effectiveness of the transradial artery approach (TRA) for treating malfunctioning arteriovenous fistulas (AVFs) in patients on hemodialysis. Materials and Methods A retrospective analysis was conducted in this single-center study of TRA endovascular procedures in 73 patients (43 male and 30 female; mean age of 67.4 years (range, 42-92 years) with malfunctioning AVFs, between January 2008 and April 2019. Patients' baseline and lesion characteristics, technical and clinical success, and complications were evaluated, and functional patency was analyzed using the Kaplan-Meier method. Results Radial artery approaches were successful in all patients. Angioplasty performed using the TRA achieved technical and clinical success rates of 98.6%(72/73) and 91.7%(67/73), respectively. The median primary patency time was 18.8 ± 15.9 months. The primary functional patency rates at 3, 6, and 12 months were 82.1%, 68.6%, and 63.9%, respectively. There were no major complications or adverse events, such as hand ischemia, related to the radial artery approach. Conclusion In selected cases, the TRA can be used complementary to the transvenous approach to treat malfunctioning AVFs.
