In the present study, a lipopeptide (named AXLP14) antagonistic to Xanthomonas oryzae pv. oryzae (Xoo) was obtained from the culture supernatant of Bacillus amyloliquefaciens B014. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis demonstrated that AXLP14 consisted of surfactin homologs. The minimum inhibition concentration and minimum bactericidal concentration of AXLP14 against Xoo were determined to be 1.25 and 2.50 mg/ml, respectively. At a concentration of 0.613 mg/ml, AXLP14 strongly inhibited the formation of Xoo biofilm. AXLP14 also inhibited the motility of Xoo in a concentration-dependent manner. Applying AXLP14 to rice seedlings significantly reduced the incidence and severity of disease caused by Xoo. In Xoo-infected rice seedlings, AXLP14 strongly and continuously up-regulated the expression of both OsNPR1 and OsWRKY45. In addition, AXLP14 effectively inhibited the Xoo-induced up-regulation of the expression of the abscisic acid biosynthesis gene OsNECD3 and the abscisic acid signalingresponsive gene OsLip9, indicating that AXLP14 may protect rice against Xoo-induced disease by enhancing salicylic acid defense and interfering with the abscisic acid response to virulence.

Salmonellosis is commonly associated with meat and poultry products, but an increasing number of Salmonella outbreaks have been attributed to contaminated vegetables and fruits. Enteric pathogens including Salmonella enterica spp. can colonize diverse produce and persist for a long time. Considering that fresh vegetables and fruits are usually consumed raw without heat treatments, Salmonella contamination may subsequently lead to serious human infections. In order to understand the underlying mechanism of Salmonella adaptation to produce, we investigated the transcriptomics of Salmonella in contact with green vegetables, namely cabbage and napa cabbage. Interestingly, Salmonella pathogenicity island (SPI)-1 genes, which are required for Salmonella invasion into host cells, were up-regulated upon contact with vegetables, suggesting that SPI-1 may be implicated in Salmonella colonization of plant tissues as well as animal tissues. Furthermore, Salmonella transcriptomic profiling revealed several genetic loci that showed significant changes in their expression in response to vegetables and were associated with bacterial adaptation to unfavorable niches, including STM14_0818 and STM14_0817 (speF/potE), STM14_0880 (nadA), STM14_1894 to STM14_1892 (fdnGHI), STM14_2006 (ogt), STM14_2269, and STM14_2513 to STM14_2523 (cbi operon). Here, we show that nadA was required for bacterial growth under nutrient-restricted conditions, while the other genes were required for bacterial invasion into host cells. The transcriptomes of Salmonella in contact with cabbage and napa cabbage provided insights into the comprehensive bacterial transcriptional response to produce and also suggested diverse virulence determinants relevant to Salmonella survival and adaptation.

Marine reservoir correction $({\Delta}R)$ values are measured using two species of mollusk tests collected by NFRDI in 1942 before nuclear bomb testing to convert the radiocarbon age to calendar age in Korean coastal waters more accurately. The ${\Delta}R$ values are calculated to be $-117\pm45\;^{14}C\;yr$ in the southwestern coast of Korea and $-160\pm35\;^{14}C\;yr$ in southeastern coast. These values are similar to those in Chinese coast of the Yellow Sea $(-81\pm60\~-178\pm50\;^{14}C\;yr$, indicating that regional reservoir $^{14}C$ ages of these areas are lower than mean global reservoir $^{14}C$ age. The lower ${\Delta}R$ values in these areas are presumed to be mainly caused by influence of fresh-water inflow. The ${\Delta}R$ values presented In this study enhance the accuracy in converting radiocarbon age to calendar age in Korean coastal waters.

Objectives: The purpose of the study was to investigate factors affecting health risk behavior, oral health related quality of life (OHIP-14) and happiness in soldiers. Methods: Data were collected from Gangwon and Chungchong provinces from the first to the $15^{th}$ of October, 2016. Excluding five copies with incomplete answers, 203 copies of the questionnaire were were analyzed. Health risk behaviors (drinking and smoking), perceived oral health, OHIP-14 and happiness were measured. The data were analyzed with a t-test, one-way ANOVA, Pearson correlation coefficient and multiple regression using the SPSS 22.0 program. Results: The amount of daily cigarette consumption of soldiers (66 people) was an average of 10.11 cigarette. The mean of OHIP-14 and that of happiness were 4.43 and 4.05, respectively. The higher the quality perceived oral health, the better the OHIP-14 (r=0.234) and happiness (r=0.192) were. The higher the OHIP-14, the higher the happiness (r=0.357). OHIP-14 was related to army, perceived oral health and happiness. The explanatory power of the model was 17.0%. Conclusions: OHIP-14 is associated with happiness. These results suggest that oral health education programs and policies need to be developed to instill happiness in soldiers.

The methods for determining C-14 and tritium contents in the spent nuclear fuel sample were developed. The carbon-14($^{14}CO_2$) released during the dissolution of the spent fuel sample and $CaCO_3$ ($CO_2$ carrier) with 8 M $HNO_3$ at $90^{\circ}C$ was collected in trap containing 1.5 M NaOH. The volatile radioactive iodine evolved when the spent fuel was dissolved, was trapped on to Ag-silicagel (Ag-impregnated silicagel) adsorbent in column which is connected to two NaOH traps. The solutions which contain tritium as HTO after fuel dissolution were decontaminated by deionization with a mixture of cation and anion exchange resins and inorganic ionexchangers. The amount of C-14 in the trap solutions and the HTO concentration in the resulting deionization water were then determined by liquid scintillation counting.

Objectives : The aim of this study was to assess the quantitative characteristics of pressure pain threshold (PPT) and pressure depth (PD) at the abdominal conception vessel (CV) acupoints according to subjective digestive status and digestive discomfort levels, accomplished by comparing a large group of healthy men and women, using the modified digital algometer. Methods : A total of 1,504 healthy adults aged 19 years or older participated in this study. A questionnaire was administered to evaluate participants' digestive status and discomfort. PPT (kgf/cm²/s) and PD (mm) measurements were obtained at CV14, CV12, and CV4 acupoints using a modified digital algometer. General characteristics were analyzed using the chi-square test, and differences in PPT and PD were assessed using two-sample t-tests and ANCOVA. Results : Significant difference in PPT was found based on digestive status at CV14 and CV12 for both sexes, and in PD at CV14 for women. Women exhibited significant difference in PPT based on digestive discomfort at CV14, CV12, and CV4, while men showed significant difference at CV14 and CV12. Significant difference in PD was observed at CV14 and CV4 among women. Even after adjusting for age and body mass index, significant difference persisted in PPT based on digestive discomfort at CV14 and CV12 for both sexes. PD exhibited significant differences at CV14, CV12, and CV4 among women. Conclusions : Using the modified digital algometer, this study showed the significant difference of pressure pain threshold at the CV14 and CV12 acupoints for subjective digestive discomfort levels in healthy men and women.

Purpose: The purpose of this study was to verify the validity and reliability of the Type D Scale-14 (DS14). Methods: The participants were 288 patients who were diagnosed with angina pectoris, myocardial infarction, and hypertension. DS14 was developed by Denollet(2005) and consists of two domains, 7 items on negative affectivity (NA) and 7 items on social inhibition (SI). The Korean version of DS14 was developed through translation-reversed translation and a preliminary test. Data were collected using a self-report questionnaire. Cronbach $\alpha$ and Guttman split-half were used to test reliability and item analysis and factor analysis for validity. The SPSS program was used. Results: 35.8% of the participants were classified as Type D. Mean score for NA was 16.80 and for SI, 14.10 in Type D participants. For reliability of NA, Cronbach $\alpha$=0.771, and for SI, 0.707. Factor analysis on 12 items(numbers 1 & 3 were excluded as the corrected item-total correlations were below r=0.3) yielded two factors for NA (6 items) and SI (6 items). Number 7 in the NA domain was sorted into the SI domain. Conclusion: The results indicate, the cultural differences were between Europeans and Koreans. Repetition of the research is needed for generalization of DS14.
