The purpose of this study is to identify which factors of medical service quality were considered important by patients based on survey on eight hospitals located in Seoul. We analyzed the difference in impact of health service quality factors between the two groups with short and long inpatient days. In addition, we analyzed which service factors affected the customer satisfaction more differently across the inpatient groups. We found that patient satisfaction was not different between the two groups with short and long inpatient days. But the two groups showed different priority orders of medical service factors that affect patient satisfaction. In the group with long inpatient days, the order of medical service factors are cleanness, speciality, process. In the group with short stay, important factors are speciality, cleanness and convenience of facilities. These findings imply that hospitals should set up different marketing strategies across the different inpatients groups.

Plastics are consistently produced owing to their practicality and convenience. Unmanaged plastics enter the oceans, where they adversely impact marine life, and their degradation into nano-plastics due to sunlight and weathering is of concern for all living beings. Nano-plastics affect humans via the food chain, emphasizing the necessity for effective solutions. Microbial biodegradation has been suggested as a solution, offering the advantages of minimal environmental impact and the utilization of decomposition byproducts in microbial metabolic pathways. In this study, fifty-seven bacterial strains were isolated and identified from a waste-treatment facility. Cultivation in a minimum medium with low-density polyethylene (LDPE) beads as the sole carbon source resulted in the selection of the LDPE-degrading strain Acinetobacter guillouiae PL211. The selected strain was cultured at high cell density with LDPE as a carbon source, and Fourier transform infrared (FT-IR) analysis confirmed chemical changes on the LDPE bead's surface. Field-emission scanning electron microscopy (FE-SEM) analysis revealed substantial biodegradation of the LDPE surface. These results demonstrated the capability of A. guillouiae PL211 to biodegrade LDPE beads. This discovery demonstrates the potential of an environmentally friendly process to addressing polyethylene waste issues.

A lot of research on the application of GIS has been conducted in the field of water quality management. The function of a geometric data acquisition for reservoir and river models, however, is not enough to satisfy multiuser' convenience. CE-QUAL-W2 is a two-dimensional(2D) longitudinal/vertical hydrodynamic and water quality model for surface water bodies, modeling eutrophication processes such as temperature-nutrient-algae and sediment relationships. The purpose of this study is to analyzing which bathymetry information affects hydraulic results. There are consisted of three scenarios under consideration. The first scenario takes into account only tribatary type data such as Heoin and Okchen river. The second scenario, Heoin river constructs to tributary and Okchen river constructs by branch. Last scenario constructs Heoin and Okchen river by branch. The RMSE error results for the first, second and third scenarios are 0.61, 0.36 and 0.28 respectively.
