In recent years, some experts have shown that urban competitiveness is more important than national competitiveness. They have also argued that innovation will make cities more competitive. The purpose of this paper is to create Korean urban competitiveness index, and to also highlight strategic aspects for enhancement of urban competitiveness of metropolitan cities based on innovation in Korea. First, we will present various factors and indicators of urban competitiveness based on three components for innovation: formation of cluster, human capital, creative economy. Available literature and statistical analyses will be used. Second, scores of urban competitiveness will be developed based on Analytic Hierarchy Process (AHP). Evaluation of scores with weights will be used for this purpose. The resulting weights are 0.3672 for the formation of cluster, 0.3318 for human capital, and 0.3010 for creative economy, respectively. Finally, we present urban competitiveness using the standardized T-score. The most competitive city based on innovation is Daejeon(1st), followed by Gwangju(2nd) and Daegu(3rd). Three least competitive cities are Incheon (6th), Busan(5th) and Ulsan(4th).

The purpose of this study was to investigate the prevalence, toxin gene profiles, and enterotoxin producing ability of Bacillus cereus isolated from environment-friendly vegetables and good agricultural practices (GAP) vegetables. A total of 49 vegetables including 40 environment-friendly vegetables and 9 GAP vegetables were tested. The Vitek 2 system was used to identify B. cereus and the PCR was used to detect 6 toxin genes, respectively. B. cereus was detected in 34 (69.3%) of 49 vegetables and the prevalence of B. cereus in GAP vegetables (44.4%) was lower than in the environment-friendly vegetables (75.0%). The detection rates of entFM, nheA, hblC, and cytK enterotoxin genes, respectively, among all isolates were 100%, 97.0%, 88.2%, and 73.5%, respectively. All of the isolates had at least one or more enterotoxin gene and 20 isolates (58.8%) had hemolysin BL enterotoxin producing ability. The risk of food poisoning from the environment-friendly vegetables and the GAP vegetables has been shown as constant. Thus, it is necessary to expand the supply of GAP vegetables showing lower B. cereus contamination than the environment-friendly vegetables. The characteristics of the environment-friendly vegetables and the GAP vegetables that must be consumed after cleaning should be disseminated to consumers regarding food poisoning prevention.
