  • A study was done to compare the properties of artificially deteriorated silk with ultraviolets for reinforcing of loss area of paintings on silk. Deteriorated surface of raw silk irradiated by long-wavelength ultraviolet(UV-A) than short-wavelength ultraviolet(UV-C) was similar to naturally aged raw silk. UV-A irradiation raw silk was slowly decreased in tensile tenacity and elongation and lowered in yellowness index than that of UV-C. Water content of UV-A irradiation raw silk than that of UV-C was higher. UV-A irradiation raw silk had no problem in dyeing and inpainting for conservation because of low yellowness index. UV-C irradiation raw silk was brittle, but UV-A irradiation raw silk was seemed to tough and similar to naturally aged raw silk. Korean painting conservator estimated that UV-A irradiation raw silk was more proper for reinforcing of loss area of paintings on silk than that of UV-C.

During the COVID-19 pandemic, Relationship between smart device usage time, eye health status, and eye health awareness among health college students (COVID-19 판데믹 시기에 보건계열대학생의 스마트기기 사용시간, 눈건강 실태, 눈건강 의식 간의 관계)

  • This study was conducted to confirm the relationship between smart device usage time, eye health status, and eye management consciousness during the COVID-19 Pandemic period for college students in the health field. The study participants were 188 health-related university students, and data analysis was performed using descriptive statistics, independent t-test, Chi-square test, one-way ANOVA, and Pearson's correlation coefficients using the SPSS 26.0 program. As a result of the study, the average of the subjects' eye fatigue score was 15.23±13.71, the dry eye subjective symptom score was 21.87±12.02, and the eye health management consciousness score was 3.48±1.09. Eye care awareness, dry eye symptoms (r=.152, p=.005) and eye fatigue, dry eye symptoms (r=.650, p<.001) were statistically significant positive correlation in the group using smartphones for 2 hours or more per day on average. Based on the results of this study, it is necessary to find a way to prevent eye health due to the use of smart devices by college students, and repeated studies are needed to confirm the factors affecting eye health.
