The structural stability of the recycled concrete disposal container was evaluated and compared the applicability of the current design standards for recycled concrete of nuclear power plant. The structural stability requirement for concrete disposal containers is 37.7 MPa or more. As a result of the compressive strength test on recycled concrete, 50% of coarse aggregates of recycled concrete was 42.1 MPa. In addition, it was found that the bending strength and shear strength of recycled reinforced concrete beam exceeded the current design standard. Therefore, it is judged that recycled concrete containing coarse aggregates can be sufficiently utilized. It was possible to ensure the structural stability of the concrete container without changing the design specifications and reinforcing bars when recycled concrete is applied.

Compared to the early 2000s, the number of tourists in Korea has increased significantly. Approximately 40 million tourists visit Korea each year. In line with this trend, various technologies for developing tourism content have reached a very high level. Therefore, adding experience-oriented AR (Augmented Reality) game based on LBS (Location-Based System) to existing tourist contents will create a new tourism content platform that can give new experience to tourists . This paper proposes a tourism contents platform based on Suwon Hwaseong Fortress which can give such a new experience.

This study examines the role of visual merchandising (VMD) in creating effective interior displays for fashion “select shops”(shops that carry a wide selection of brands) amid the recent changes in consumption trends, with consumer needs becoming increasingly individualized and diversified. Fashion select shop interior displays can be categorized as self-service, showcase, counter, and environmental display spaces. Regarding the VMD elements that contribute to effective interior displays, we reached the following conclusions. First, in self-service displays, in order to heighten sales efficacy, display elements should be presented in such a way as to enable customers to select products with ease by themselves. Second, the mere presence of showcase displays was found to be insufficient; if, however, select shops use showcase displays to arrange products according to the flow of customer traffic, enabling the creation of a gentrified atmosphere for products, this may contribute to a differentiated image of brands, heightening perceived product value. Third, in counter displays, having a harmonious arrangement of display and presentation elements promotes sales by inspiring customer confidence. Fourth, regarding environmental displays, it is important for stores to have attractive interior designs and decorations in order to reproduce settings in which products are actually used, as this can inspire interest in products and promote customers’ purchasing intention.

Antibiotic resistance in animal isolates of enterococci is a public health concern, because of the risk of transmission of antibiotic-resistant strains or resistance genes to humans through the food chain. This study investigated phenotypic and genotypic resistances profile of tetracycline in 245 Enterococcus isolates from bovine milk. A total of 245 enterococci were isolated from 950 milk samples. The predominant strain was E. faecalis (n = 199, 81.2%) and E. faecium (n = 25, 10.2%). E. avium (n = 7, 2.9%), E. durans (n = 6, 2.5%), E. gallinarum (n = 4, 1.6%), and E. raffinosus (n = 4, 1.6%) were also isolated. Of the 245 enterococcal isolates 76.3% (n = 187) displayed tetracycline resistance (≥ 16 μg/ml). Of the 187 tetracycline-resistant isolates, 83.4% (n = 156), 16.1% (n = 30), and 26.7% (n = 50) possessed the genes tet(M), tet(L), tet(S) respectively. While 3.2% (n = 6) of the tetracycline- resistant isolates possessed all three genes tet(M) + tet(L) + tet(S), 8.6% (n = 16), 16.0% (n = 30), and 2.7% (n = 5) of them possessed two genes tet(M) + tet(L), tet(M) + tet(S), and tet(L) + tet(S) respectively. The tetracycline resistance pattern investigated in this study was attributable mainly to the presence of tet(M).
