ABSTRACT
This study examined and verified the level of e-health literacy (e-HL) and infection preventive behaviors related to COVID-19 among undergraduate students majoring in healthcare. An online survey was conducted with 274 university students majoring in nursing, clinical pathology, and occupational therapy in South Korea. The e-HL consisted of functional, communicational, and critical literacy, and preventive behaviors were based on the Prevention Guideline on Droplet Infection. The mean score for e-HL was 3.62, with nursing students obtaining the highest scores. The overall e-HL score and the scores on its three sub-dimensions were related to infection-preventive behaviors. Moreover, e-HL affected infection-preventive behaviors (p < 0.001). Findings from this study highlight the necessity of education for improving the e-HL of undergraduate students majoring in healthcare to strengthen infection-preventive behaviors and protect patients from infectious diseases.
ABSTRACT
A Gram-staining-negative, strictly aerobic, rod-shaped bacterium, designated CBA3202(T), was isolated from seashore sand on Jeju Island, Republic of Korea. Based on the 16S rRNA gene sequence analysis, strain CBA3202(T) was allocated to the genus Gillisia (family Flavobacteriaceae) and was most closely related to the type strain of Gillisia mitskevichiae (99.0â% 16S rRNA gene sequence similarity). Optimal growth occurred at 25 °C and with 3â% NaCl. The only isoprenoid quinone was menaquinone-6 (MK-6), the predominant fatty acids were C16â:â0, iso-C15â:â1 G, iso-C16â:â0 and summed feature 3 (comprising C16â:â1ω6c and/or C16â:â1ω7c), and the DNA G+C content was 34.9 mol%. The polar lipids were phosphatidylethanolamine, two unidentified aminolipids and several unidentified polar lipids. Based on phylogenetic inference and phenotypic data, we conclude that strain CBA3202(T) represents a novel species of the genus Gillisia, for which the name Gillisia marina sp. nov. is proposed. The type strain is CBA3202(T) (â=âKACC 16693(T)â=âKCTC 32030(T)â=âJCM 18402(T)). An emended description of the genus Gillisia is also provided.

The hexagonally arranged close-packed concave nanotexture of the master surface of nanoporous alumina has been imprinted several times on aluminum films and gold films by thermal evaporation and on polystyrene films by spin coating. The degradation of the nanotextures with replica pattern transfer has been monitored by measuring the topology and the wettability of duplicated films. The trough-to-crest height of the topography decreases while the wettability of the nanotexture increases significantly as replication goes on. Air fractions calculated with measured water contact angles decrease substantially with replication although they also depend strongly on the materials and the shapes of duplicating nanotextures.
