Prevalence autism spectrum disorders (ASD) has been on rise, but many studies suggests over-diagnosed. Currently, children have more access to electronic media on the daily basis than those of previous generation. Some studies suggest that increases screen time is associated with melanopsin-expressing neurons and decreasing gamma-aminobutyric acid (GABA) neurotransmitter, and thus results aberrant behavior, decreased cognitive, and language development. Early exposure of electronic media in early life (< 2 years old) gives an impact on language, but it still inconclusive. We made a study aiming at revealing the impact of early exposure of electronic screen on language development and autistic-like behavior. Results showed that children who spent viewing ≤ 3 hours per day had language delay and short attention span, while children who spent viewing ≥ 3 hours per day had language delay, short attention span, and hyperactivity. While, we found that more than a half of children (66.6%) had no parents-child interaction during the exposure, speech delayed and short attention had been reported in all cases, and hyperactivity was found in 66.6% children.

Samples (n=18 male=7 and female=11) were taken from five and six grader and conducted in Tembalang and Pedalangan Elementary School, Semarang. Pretest were administered, followed by brain gym, and post test administered in the end of study. The measurement of Intelligence Quotient pre and post test using Culture Fair Intelligence Test Scale 2. Among the 18 subjects (male=7 and female=11) the average of academic performance and IQ score after brain gym showed improvement. The Improvement of IQ score with Culture Fair Test Scale 2 was analyzed by Dependent T test showed significant results (p=0,000). The improvement of Bahasa score was analyzed by Wilcoxon test showed significant results (p=0,001), an unsignificant result were shown in Mathematics p=0,079 and natural sciences p=0,306.

Data were collected at Diponegoro University using online questionnaire through the Google form platform regarding knowledge, actions to maintain oral health, and subjective complaints of oral health problems. Data were analyzed by using the chi-square test. The results showed that the majority of students had a high level of knowledge about dental and oral health, meanwhile, their action to maintain oral health was in moderate level. The levels of knowledge and action to maintain oral health of medical students were better than of the non-medical students. Dental and oral health problems most frequently complained were recurrent aphtous ulcers (RAU) and dental caries. The chi-square test showed a p-value of 0.023 between the action to maintain oral health and subjective complaints of oral health problems.
