Most screening instruments for autism spectrum disorder (ASD) have been developed and evaluated in western countries. Therefore, difficulties are often experienced when using these instruments because of the cultural differences in the symptoms of ASD. This paper reviews the screening instruments for ASD used in South Korea and explores a new direction in the screening of ASD in South Korea. Among the many published screening instruments for ASD, the screening instruments with a validated Korean version were chosen and reviewed. A total of nine autism-screening instruments met the criteria for the inclusion criteria. Nine screening instruments were summarized and the direction for the Korean version of screening instruments was discussed.

A 43-year-old female was admitted for a laparoscopic surgical procedure. Her past history included two uneventful general anesthesias, but anaphylactic shock due to an unknown drug occurred during her third surgery. Induction was performed with thiopental sodium, but an immediate anaphylactic reaction developed with cardiovascular collapse. We resuscitated the patient and she recovered without any complication.

OBJECTIVES:
In rural areas of Korea, where public transportation infrastructure is lacking and alternative systems are poor, the elderly experience inconveniences in using healthcare, although their need is high. This study aimed to analyze the association between the convenience of transportation and unmet healthcare needs among the rural elderly.
METHODS:
The data used were collected in the 2016 Community Health Survey among rural elderly individuals aged 65 or older. Dependent variable was the unmet healthcare needs, explanatory variable was the convenience of transportation. The elderly were divided into 3 groups: with no driver in the household, with a driver, and the elderly individual was the driver (the self-driving group). Covariates were classified into predisposing, enabling, and need factors. They included gender, age, education, income, economic activity, household type, motor ability, subjective health level, number of chronic diseases, anxiety/depression, and pain/discomfort. The data were analyzed using logistic regression and stratification.
RESULTS:
A significant association was found between the convenience of transportation and unmet healthcare needs. When examined unadjusted odds ratio of the group with a driver in the household, using the group with no driver as a reference, was 0.61 (95% confidence interval [CI], 0.54 to 0.68), while that of the self-driving group was 0.34 (95% CI, 0.30 to 0.38). The odds ratios adjusted for all factors were 0.69 (95% CI, 0.59 to 0.80) and 0.79 (95% CI, 0.67 to 0.91).
CONCLUSIONS
We confirmed a significant association between inconvenient transportation and unmet healthcare needs among the rural elderly even after adjustment for existing known factors. This implies that policies aimed at improving healthcare accessibility must consider the means of transportation available.

Objective:
This study aimed to evaluate the utility of the Korean version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT) in hospital settings and to identify items sensitive for detecting autism spectrum disorder (ASD) trait.
Methods:
The Q-CHAT was administered to a clinical sample of children presenting with developmental delays with a high probability of ASD in a hospital setting (n=37), as well as to typically developing community children (n=67), aged 12 to 54 months.
Results:
The mean Q-CHAT total score in the hospital sample (42.0±13.6) was significantly higher than in the community sample (29.9±7.8), with maximized sensitivity and adequate specificity at 32.5 (sensitivity=0.811, specificity=0.687). The internal consistency of Q-CHAT was 0.764 for the overall sample and 0.825 for the hospital sample. Q-CHAT total scores and item scores in the hospital sample remained stable across age groups, indicating age-invariant properties. The hospital sample showed higher endorsement of less favorable development in social interaction and reciprocity items compared to community sample. No difference in the Q-CHAT item scores was present among age groups in the hospital samples. In the community samples, item scores, such as comprehending a child’s speech, using the hand of others as a tool, adapting to a change in routine, repeating the same action, and making unusual finger movements, decreased with the advance of age.
Conclusion
The Korean version of the Q-CHAT demonstrates good validity and reliability and is effective in discriminating autistic traits even in children older than 24 months. The items endorsed for hospital samples varied from community samples, implying item-specific sensitivity for hospital samples.

This study compared and evaluated the color change and fracture resistance of reattached tooth fragments stored in different media after trauma. Sixty extracted permanent incisors were examined. Tap water, saline solution, milk, artificial saliva, and casein phosphopeptide-amorphous calcium and phosphate (CPP-ACP) were used as storage media. The control group used no storage media. Color changes were calculated using CIE L*a*b* values measured by a spectrophotometer at seven time points: just before reproducing the tooth fracture (T0); after drying the fractured crown for 24 hours following fracture (T1); immediately after rehydration in the storage medium for 20 minutes (T2); and 12 hours (T3), 24 hours (T4), 1 week (T5), and 3 weeks (T6) after reattaching the fractured crown. Fracture resistance was uniformly measured 3 weeks after reattachment. The results showed that the CPPACP group showed significantly more effective color recovery than the other storage media groups, with the color returning to natural levels by T2. Color recovery was observed in all groups at T6. Fracture resistance did not differ significantly between the six groups. No significant difference was observed between the storage media regarding color recovery and fracture resistance three weeks after reattachment.
