V. parahaemolyticus causes waterborne and foodborne disease such as acute diarrhea. In this study, V. parahaemolyticus isolates from seawater, fish tanks, and distributed fishery products in Jeju were investigated for potential toxin or species-specific genes (tdh, trh, tlh, and toxR) using RT-PCR and their genetic characteristics were analyzed using Pulsed-field gel electrophoresis (PFGE). Overall, V. parahaemolyticus of 90 strains (36.7%), including 33 strains from seawater, 8 strains from fish tanks, and 50 strains from fishery products, were isolated from 245 samples. All V. parahaemolyticus strains did not detect the tdh gene, whereas all strains detected tlh or toxR genes. In addition, trh genes were detected in 3 strains from seawater and 1 strain from fishery products. Monthly quantitative testing of seawater revealed that V. parahaemolyticus was positively correlated with water temperature. The 90 strains of V. parahemolyticus obtained in this study showed by gene homology between types, ranging from 64.0-97.3%. Among these, thirteen types showed 100% homology between genes. These results indicate that continuous monitoring is needed to facilitate food poisoning epidemiological investigations because some isolated V. parahaemolyticus strains harbored toxin genes and V. parahaemolyticus strains isolated from seawater, fish tanks, and distributed fishery products showed genetic similarity.

Purpose: The purpose of this study is to compare the efficacy of the current evidence based practice on peripheral venous catheter replacement. Methods: After ethics approval, 140 patients (480 intravenous devices) were enrolled in our survey. Data were analyzed by statistical methods such as t-test, frequency analysis, χ2 square, Fisher’s exact test, Kaplan-Meier survival analysis using SPSS 21 program. Results: First, the average number of inserted peripheral venous catheters in the experimental group was 2.7 (3.0 in the control group), the number of days of maintenance of the peripheral venous catheters was 3.0 days (1.8 in the control group), and the maximum maintenance day of the peripheral venous catheter was 8 days. Second, there were no differences in the incidence of phlebitis and bloodstream infection between the two groups. Third, the risk of phlebitis in the experimental group increased sharply from the 6th day after insertion of peripheral venous catheter. Conclusion: As a result of this study, peripheral venous catheter replacement by clinical signs is recommended, and after 6 days, side effects should be carefully observed. We propose an iterative study on the effect of clinical signs on peripheral venous catheter replacement by expanding the number of patients.
웹과 Text BBS의 데이터베이스 연동을 위한 자바게이트(JAVA GATEway)의 설계에 대한 연구

In this paper, the model JAVAGATE to connect WWW and the Database at the Text BBS is suggested. JAVAGATE can reduce the overhead of server that can be generated during the processor creation at the CGI(Common Gateway Interface) method to connect WWW and a database, and by using User Status Monitor can solve the problems; connectionless and stateless, user proof, user time management, and transaction status management. Also, this paper proposes a new production method of web pages by adding Form Table to the Text BBS database.
