Based upon the first national sample of adult men and women, the study aims to examine the prevalence of chid sexual abuse in Korea and factors related to the incidence of child sexual abuse. The results of the study show that 20.8% of the sample experienced one or more types of sexual abuse in their childhood, which indicates that Korean society is not any longer immune to child sexual abuse. With regard to how to cope with sexual abuse, "not informed to anyone and did not get any help at all" is the most major one for all types of sexual abuse. Even those who got help were reported to depend heavily upon private routes such as parents, relatives, or friends, indicating the urgency of establishing systematic intervention schemes for the problem. The results of a logistic regression analysis show that gender of the child, involvement in delinquent behaviors, economic status of the family, number of siblings, and residence in high-crime region are significantly related to the incidence of child sexual abuse. These results of the study would be expected to provide a useful guideline for developing policies or intervention programs aimed to prevent or address child sexual abuse.

Background: Two-jaw surgery including mandibular and maxillary backward movement procedures are commonly performed to correct class III malocclusion. Bimaxillary surgery can reposition the maxillofacial bone together with soft tissue, such as the soft palate and the tongue base. We analyzed changes of pharyngeal airway narrowing to ascertain clinical correlations with the prevalence of snoring after two-jaw surgery. Methods: A prospective clinical study was designed including a survey on snoring and three-dimensional (3D) computed tomography (CT) in class III malocclusion subjects before and after bimaxillary surgery. We conducted an analysis on changes of the posterior pharyngeal space find out clinical correlations with the prevalence of snoring. Results: Among 67 subjects, 12 subjects complained about snoring 5 weeks after the surgical correction, and examining the 12 subjects after 6 months, 6 patients complained about the snoring. The current findings demonstrated the attenuation of the largest transverse width (LTW), anteroposterior length (APL), and cross-sectional area (CSA) following bimaxillary surgery given to class III malocclusion patients, particularly at the retropalatal level. The average distance of maxillary posterior movements were measured to be relatively higher (horizontal distance 3.9 mm, vertical distance 2.6 mm) in case of new snorers. Conclusions: This study found that bimaxillary surgery could lead to the narrowing of upper airway at the retropalatal or retroglossal level as well as triggering snoring in subjects with class III malocclusion. Based on the current clinical findings, we also found that upper airway narrowing at retropalatal level may contribute to increasing the probability of snoring and that polysonography may need to be performed before orthognathic surgery in subjects with class III malocclusion.
