Abstract

Abstract: The use of smartphones in the digital era like today is increasingly intense in daily life. Not only teenagers and adults, smartphones are also widely used by children, toddlers, and even babies.  Blue light filters on smartphones are believed to reduce visual disturbances that occur due to long-term smartphone use. The purpose of this study is to analyze the effect of a blue light filter on the level of eye fatigue of students of the Faculty of Medicine, University of Muhammadiyah North Sumatra (FK UMSU). This research is quasi-experimental with a pre-posttest design. A total of 154 FK UMSU students were divided into 2 groups, the Blue Light Filter Group (BLF) and the Non-Blue Light Filter Group (Non-BLF) with the same number (n1 = n2 = 77). Each group filled out a VFS (Visual Fatigue Scale) questionnaire before and after working on the visual task. The data were analyzed using the Mann-Whitney and Wilcoxon tests. The results showed that the post-test score of the level of eye fatigue in the Non-BLF group was significantly higher than that of the BLF group (P 0.001). There was a significant difference between the pre-test and post-test results of the Non-BLF Group (P 0.001), while the pre-test and post-test results of the BLF Group showed a difference but not significant (P = 0.860). This study shows that the use of blue light filters affects the level of eye fatigue.

Abstract

Abstract: The shape of the pedis arcus affects the way of walking. Abnormal pedis arcus results in an unstable position of the legs as a body support when walking. This can cause several complaints such as imbalance, fatigue during long walks, pain and injury. Walking is one way to measure a person's fitness level. This study analyzes the relationship between the shape of the pedis arcus based on the foot print test and the VO2 Max value of FK UMSU students. This research is observational and analytical with a cross-sectional approach. The footprint test was carried out on 67 respondents followed by Clarke's angle measurement to determine the type of arcus pedis for each respondent. The body weight was then measured, followed by a six-minute walking test (6MWT) to obtain a VO2 Max value. The results obtained were that 36 (53.7%) respondents had a normal pedis arcus shape (normal foot), 13 (19.4%) high pedis arcus shape (cavus foot), and 18 (26.9%) flat foot arcus pedis shape. The results of the Somers'd test were symmetrical (P = 0.353), arcus pedis dependent (P = 0.353), and VO2 Max dependent (P = 0.353). A P-value 0.05 means that the variable of the shape of the arcus pedis and the fitness level (Vo2max value) is not proven to affect each other, so it can be concluded that the shape of the arcus pedis is not related to a person's fitness level.
