Purpose: The purpose of this study was to compare subjective symptoms of VDT between computer-addicted and non-addicted adolescents. Method: A descriptive survey design was used and 646 students in one middle and two high schools were selected as participants. Result: The VDT subjective symptoms and degree of severity differed according to whether the students were computer-addicted or not, and in all symptoms, general, musculoskeletal, eye and mental, the mean score for subjective symptoms was higher in the addicted group than in the non-addicted group. The score for VDT subjective symptoms was highest in the addicted group for girls and students who were not healthy. The most frequent physical symptom reported by students who visited the school health room for a health problem after using the computer was headache. The most frequent type of treatment at the school health room was treatment of the symptom. Conclusions: This study suggests that students must acquire correct habits in computer use and be careful not to be addicted to the computer in order to avoid VDT syndrome. For this, educational authorities should develop computer-related health education programs and start the programs from the lower grades of elementary school.

The purpose of this study was to confirm the relationship between the subjective symptoms of smartphone addiction and visual display terminal syndrome in nursing college students and learning flow in the COVID-19 pandemic. For the collection of materials, the materials of the final 134 people were analyzed by collecting the students at the nursing colleges located in S city and M city for convenience. The collected materials were subjected to descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficients using the SPSS / WIN 26 program. As a result of this study, the learning flow of nursing college students was negative correlated to the tendency of smartphone addiction and the subjective symptoms of visual display terminal syndrome. Therefore, to improve the learning flow of nursing college students, it is necessary to reduce the symptoms of smartphone addictive use and visual display terminal syndrome.

The purpose of this study was to identify the relation between mobile phone use and visual display terminal syndrome symptom experience in female students from middle school and high school. The convenience sample consisted of 349 female students in four schools. The data were collected from May to June in 2013 using VDTS Subjective Symptom Questionnaire. Descriptive statistics, Kruskal-Wallis test, and Mann-Whitney U test were used to analyze the data using SPSS 21.0. Almost all (96.3%) female students use mobile phone. Among them, 87.7% of the subjects experienced more than one VDTS symptom and the average score was $.39{\pm}.41$ in VDTS symptom experience. Eye related symptom was most experienced and musculoskeletal symptom was the highest in severity among five subdomain of VDTS symptoms. There were significant differences in VDTS symptom scores in accordance with posture, hours of use, and break type during mobile phone use. These findings suggest that the education program for adolescents would be necessary, and the development of checklist would be useful for adolescents to check themselves.
