  • Acidovorax citrulli is a causal agent for bacterial fruit blotch on watermelon. Here, we report the complete genome sequence of A. citrulli strain KACC17005. The genome contains 5,349,924 bp with G + C contents of 68.54%, including 4,520 protein coding genes in a circular chromosome. It also possesses at least 15 genes encoding putative type III effector proteins, which may contribute to promoting virulence in susceptible hosts or triggering immune responses in resistant hosts.

  • As the compact and easily accessible handheld devices, such as cellular phones and MP3 players equipped with image acquisition functionality, are becoming widely available among common users, various applications of images are rapidly increasing. Image related services and software such as web-based image presentation and image manipulation for personal or commercial purpose enable users to view contents of remote image archive and to manipulate enormous amount of images in local or network based storage as well. It is necessary for users to identify the images efficiently so that the same images are perceived as one physical entity instead of recognizing them as different images as the trends are getting stronger. In order to support this environment, we propose a method that generates image identifiers or indexing for images within a solid and efficient manner. The proposed image identifier utilizes multiple index values. The integration of component index values creates a unique composite value that can be used as a file name, file system identifier, or database index. Our experimental results on generation of constituent index values have shown favorable results.

  • Garlic is one of the most popular seasoning bulb vegetables in Korea and is the most commonly used food ingredient. However, the cultivation areas are decreasing every year as the price drops due to imported garlic, and labor is insufficient to produce garlic by conventional methods. Cultivation requires various tasks until garlic is harvested. Seeding is one of the important and laborious tasks; thus, mechanization is necessary. When seeding garlic, the sprout should face upwards; otherwise, it may rot or produce poor quality garlic. This study investigated the extent of growth of northern- and southern-type garlic in eight different positions. The results show when the roots were not planted properly, the stems were weak, and the garlic bulbs were small. A simple garlic planter was manufactured with a crank-press mechanism to plant garlic in an upright position. Using this machine, a three-fold experiment was carried out with 100 strips of garlic. The test results showed that 99.4% of the planted garlic strips were positioned upright or close to being upright, and 0.6% failed to take root. An image processing algorithm was developed to locate the root part of the garlic, and the result showed a success rate of 81%. A future study will develop an automatic garlic upright planting system with a viewing system.

  • The methanol extracts of flowers obtained from 67 plant species were screened for their inhibitory activity on aldose reductase (AR). Alnus japonica, Aster spathulifolius, Chionanthus retusus, Morus bombycis, Crysanthemum boreale, Persicaria tinctoria, Platycarya strobilacea, and Serratula coronata var. insularis exhibited potent aldose reductase inhibitory (ARI) activity. HPLC-UV analysis of quercetin, an AR inhibitory flavonoid, was performed on extracts showing strong ARI activity. Quercetin was detected in C. retusus, C. boreale, P. tinctoria, and S. coronata var. insularis at concentrations of 1.33, 1.56, 0.82, and $3.37mg\;g^{-1}$ extract, respectively, indicating that quercetin contributed to the ARI activity of these extracts. In the samples in which quercetin was absent, other compounds may be responsible for their potent ARI activity. These results serve as a basis for further studies regarding the bioactive components responsible for the inhibitory effects of various flower extracts on AR activity.

  • Objective: The aim of this study was to provide a systematic review of the Korean literature on the influence of herbal medicine on liver function. Additionally, we tried to estimate the change in the data on liver function tests (LFTs) and the incidence of liver injury (LI) after taking herbal medicine. Methods: Systematic literature searches were performed on 6 major Korean databases (Research Information Sharing Service (RISS), Korea Institute of Science and Technology information (KISTI), National Assembly Electronic Library, Korean Medical database (KMBASE), Korean Traditional Portal, and Dongui University Electronic Library) from January 2010 to June 2020. No restrictions were placed on the types of publications, which included grey literature. Results: The data indicate that herbal medicine might be a minor cause of LI in Korea. However the results are not supported strongly enough to verify the safety issues because of the limitations of the original studies. Conclusions: Additional well-planned studies are still needed that can overcome the heterogeneity and the considerable methodological flaws in the analyzed studies.

  • On the research for constructing secure group-oriented proxy signature schemes, there are several proposals of threshold proxy signature schemes which combine the notions of proxy signature with threshold signature. Recently, Hsu and Wu proposed a threshold proxy signature scheme which uses a self-certified public key based on discrete logarithm problem. In this paper, we show that this scheme is vulnerable to original signer's forgery attack. So our attack provides the evidence that this scheme does not satisfy nonrepudiation property.

  • In the process of creating drawings based on Building Information Modeling (BIM), automatically generated annotations can cause interference issues depending on the drawing type. This study aims to develop an algorithm for repositioning annotations using genetic algorithms to minimize such interferences. To achieve this, the Application Programming Interface (API) of BIM software was used to analyze data extractable from BIM drawing files. The process involved defining drawing data related to annotation repositioning, preprocessing this data, and deriving optimal placement coordinates for the annotations. Furthermore, applying the developed algorithm to the preliminary design drawings of small and medium-sized neighborhood facilities resulted in approximately a 95.37% decrease in annotation interference, indicating that the proposed algorithm can significantly enhance productivity in BIM-based drawing tasks.

  • Purpose:Hypopharyngeal carcinoma is usually diagnosed as an advanced disease after an asymptomatic beginning, and it is related to a high frequency of lymph node metastases. An eventual negative outcome may occur not only because of possible locoregional failures but also for frequent distant metastases. Thus, the efficacy of induction chemotherapy followed by radiation therapy, with regards to the response, survival rate and complications for locally advanced hypopharyngeal carcinoma patients, was examined. Methods and Materials:Since July 1998 to February 2001, 18 patients having locally advanced hypopharyngeal carcinoma were treated with induction chemotherapy followed by radiation therapy, and the results were retrospectively analyzed. The regimen of the induction chemotherapy was the 5-flurouracil(5-FU, 1,000mg/$m^2$ daily for 5 consecutive days) and cisplatin(100mg/$m^2$ on day 1) combination at 3-week intervals for 2 cycles. The total radiation dose for the primary tumor and metastatic lymph nodes was 68.4-72.0Gy(median:70.2Gy) Results:The 3-year overall survival rate and disease free survival rate were 31.3% and 22.2%, respectively. In 6 patients(33.3%), preservation of the larynx for over 3 years was possible. After the induction chemotherapy and radiotherapy, a complete response was noted in 14 patients(77.8%), and a partial response in 4 patients (22.2%), with an overall response rate of 100%. Conclusion:Induction chemotherapy followed by radiation therapy is an effective treatment and larynx preservation rate was 33% in patients with locally advanced hypopharyngeal carcinoma in our report.
