Purpose: To describe the characteristics and investigate the differences of higher-order aberrations (HOAs) between the eyes with a natural, uncorrected visual acuity (UCVA) of 20/12 and eyes with highly myopic eyes in Korean adults. Methods: Thirty-one eyes of 20 subjects with UCVA of 20/12 (Group 1) and 54 eyes of 36 myopic patients with greater than -6 diopters (Group 2) were analyzed for type and magnitude of HOAs across a 6.0 mm pupil. HOAs were measured by Wavescan (VISX, Santa Clara, CA, USA) in natural scotopic conditions and were presented as root-mean-square (RMS:μm) in Belle aberration maps. Results: The mean spherical equivalent (SE) of manifest refraction was -0.15±0.25 D (range: +0.37 to -0.50 D) in Group 1 and -7.25±0.78 D (range: -6.00 to -9.25 D) in Group 2. The total root-mean-square (RMS) values of HOAs for Group 1 and Group 2 were 0.28±0.09 μm and 0.27±0.087 μm, respectively (P>0.05). The mean values of coma, trefoil, and spherical aberration were 0.14±0.091 μm, 0.14±0.089 μm, 0.091±0.059 μm in Group 1 and 0.16±0.077 μm, 0.14±0.073 μm, 0.082±0.059 μm in Group 2, respectively. Conclusions: This study helped establish ocular aberration standards for those with natural supervision and those with highly myopic eyes among Koreans. Individuals with natural supervision had significant amounts of HOAs, and there was no significant difference in the amount of HOAs between the two groups. The index of higher-order aberrations may not be a perfect predictor of the amount of refractive error. Korean Journal of Ophthalmology 21(2):79-84, 2007

The purpose of this study, undertaken from May to August 2016, was to investigate oral health behavior and preventive language literacy in 220 workers active in a variety of industries. Data was collected from a subject group comprising 37.7% women and 62.3% men, with an average age of 32.7 years. The group was relatively well educated, 75.9% having graduated university, and the average monthly household income was 32.3%. Over half the subjects, 56.8%, were single rather than married. In terms of oral health behavior, 65.5% who did not undergo regular checkups with regular checkups. Among the subjects, 63.2% were regularly had their teeth scaled. 60.5% of the subjects did not have oral health education, and 35.9% expressed difficulty understanding the termi-nology used in dental treatment. The dental practitioners were 56.8%. Oral health behavior and lan-guage comprehension related to prevention were significant in the presence of periodic screening, periodic scaling, oral health education experience, dental treatment and oral health education.
