Objectives : The purpose of this study was to analyze the factors related to the disclosure patterns of sexual abuse in children and adolescent victims. Methods : A sample of 153 children and adolescents who visited the Sunflower children's Center (Incheon) between January 1, 2011 and December 31, 2012 were analyzed. The medical records of the victims were reviewed retrospectively. Results : Ninety (58.8%) subjects made a disclosure of sexual abuse voluntarily. The revelation was most commonly made to a parent. The severity and duration of sexual abuse were related to the disclosure patterns. In addition, the group that displayed below average intelligence, particularly subjects in the group with borderline intellectual functioning, tended to disclose their history of abuse less voluntarily than the subjects with normal intelligence. Conclusion : The current study provides insight into the factors that affect disclosure patterns in children and adolescent sexual abuse victims. To prevent sexual abuse, we suggest that special legal assistance and social concern be required for children and adolescents with borderline intellectual functioning.

Objectives: This study aimed to investigate the trajectory of change of diverse attention and working memory in Koreans from 4 to 40 years of age. Methods: The data of 912 subjects from 4 to 15 years of age obtained from a previous standardization study of the computerized comprehensive attention test were merged with the newly obtained data of 150 subjects aged 16 to 40 years from this study. We evaluated the various kinds of attention, in which each subtest had five indicators. Working memory, with parameters such as number of correct responses and span, was also measured. Results: Our findings indicated that attention developed as age increased, and it decreased or was maintained after a certain age. Selective and sustained attention developed rapidly in children and adolescents, until mid-teens or 20 s when it ceased development. Divided attention, however, developed up to approximately age 20. In addition, working memory developed until mid-teens or 20 s. Conclusion: We presented the standardized data on diverse kinds of attention and working memory in children, adolescents, and adults in Korea. We could recognize any patterns of change in attention and working memory with increasing age.

The study classifies and analyzes the lower-body-shape types of female adolescents aged 14 to 16 years to provide meaningful information for making ready-to-wear patterns that are suitable for various female adolescent body types. The body-size data of 830 females aged 14 to 16 years were analyzed from 6th Size Korea anthropometric study. A factor analysis of 27 measurement items related to the lower body extracted 3 factors: waist/upper legs, height of the lower body, and hip area. A cluster analysis classified the female adolescent lower-body types into four clusters: the skinny body type with the shortest lower-body length, the most obese body type with the largest girth, the normal body type with the longest hip length, and the slender body type with the longest lower-body length. The discriminant analysis determined that nine measurement items had the most influence on classifying lower-body-shape types, and discriminant functions were derived. These results are meaningful because they provide more precise information about lower-body-shape types.

Purpose : This study was conducted to improve cognitive oral healthcare care by analyzing the correlation between oral health behavior and oral health status Korean adolescents. The subjects were 65,528 youths in 798 schools monitored in the Twelfth Korea Youth Risk Behavior Web-based Survey in 2016. Methods : The general characteristics consisted of 9 items including sex, grade, and academic performance. The academic performance and economic status were restructured into "upper, middle, lower". Subjective health perception and subjective oral health perception were reorganized as "health", "normal", "no health". The sub-areas of oral health behavior include five times of daily brushing during the day yesterday. The number of brushing times was "0", "1-2", "3", "more than 4" After lunch at school, brushing was restructured as "always," "sometimes," "not." The oral health status subscale consisted of 6 items including tooth breakage and toothache at the time of eating. Result : Tooth fracture(43.7 %), pain in mastication(43.7 %), tooth tingling(47.4 %), gum pain and bleeding(45 %), pain in buccal mucosa(43.8 %) and halitosis(46.6 %) were rare in adolescent having healthy oral health status cognitively(P<.001). Nosymptom adolescents without dental sealant showed low tooth fracture(0.64 times), pain in mastication(0.67 times), tooth tingling(0.59 times), gum pain and bleeding(0.84 times), pain in buccal mucosa(0.76 times), and halitosis(0.90 times). Nosymptom adolescents without scaling showed low tooth fracture(0.88 times), pain in mastication(1.03 times), tooth tingling(0.82 times), gum pain and bleeding(0.64 times), pain in buccal mucosa(0.70 times) and halitosis(0.82 times). Conclusion : This study revealed that oral health status is correlated with oral health behavior. Development of educational media and program, and aggressive promotion required to establish oral health Korean adolescent.

Objects : This study was attempted to evaluate the body image and the self concept in high risk adolescents for eating disorders. Methods 589 middle school students were investigated with EAT(Eating Attitude Test) and BITE(Bulimic Investigatory Test Edinburgh) and Schematic Figures(Child/Adolescent Version) and Piers-Harris Self-Concept Scale. According to the score of EAT and BITE, three high risk groups(high EAT group, high BITE group, high EAT & BITE group) were identified. Three groups were examined in terms of sex, weight, self concept and body image. Each group was EAT group, BITE group, EAT & BITE group Results: The results of the study were as follows : 1) EAT & BITE group showed greatest body image distortion. 2) BITE group and EAT & BITE group showed lower score in self concept scale. 3) The majority of EAT group were boys, BITE group and EAT & BITE group were mostly girls. 4) All three high risk groups, especially Bin group, revealed overweight compared with normal control group. Conclusions : High BITE group and high EAT & BITE group could be considered as significantly high risk groups for eating disorders, showing overweight, severe body image distortion, and poor self concept. EAT score alone seemed not to discriminate high risk adolescents for eating disorders.

Purpose: This study was to assess the association of internet addiction and depression, stress and suicidal ideation among adolescents. Methods: The authors have surveyed 2 middle schools and 2 high schools located in Seoul and analyzed 525 questionnaires. The questionnaire included the Internet Addiction Self Diagnosis Index (K-index), Child Depression Index (CDI), Stress Index and Reynold's Suicidal Ideation Index. Structural equational model analysis was done to explore the association between internet addiction and suicidal ideation. Results: The adolescent internet addiction groups were classified as the high risk group 12 (2.3%), the potential risk group 64 (12.2%) and the normal group 449 (85.5%). When classified according to sex, the high risk group is consisted of 8 (3.9%) boys, 4 (1.3%) girls and the potential risk group is consisted of 41 (64.1%) boys and 23 (35.9%) girls which leads to the conclusion that boys are relatively more addicted compared with girls. The group with more addiction showed higher depression scores, stress scores and suicidal ideation scores. The correlation analysis showed the significant relations between internet addiction and depression (r=0.263), stress (r=0.265) and suicidal ideation (r=0.284). According to the structural equation model analysis, internet addiction had direct effects on the depression and indirect effects on suicidal ideation. Stress had the significant direct effects on both internet addiction and depression. Depression had a significant direct effect on suicidal ideation. Conclusion: Internet addiction affects directly and indirectly an depression and suicidal ideation among adolescent.

Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.

Recently, there has been an increasing social concern over the use of random reward game items. In this paper, we try to understand the effect of using random reward game on adolescents based on the survey data over a year. In addition, regression analysis was conducted to examine how socio-psychological variables affect the game addiction of adolescents according to use of random reward games. As a result of analysis, it was found that the random reward game use group had lower self esteem and higher material value than the normal game use group. Also, self esteem and material value have a significant effect on game addiction. And finally, the results and implications were discussed.

Objective: This study aimed to analyze the effects of computer game exposure on pathological musculoskeletal symptoms in adolescents. Method: This study included 10 male junior high school students who used computers less than 3 times a week for 1 hr per day. The subjects were asked to play computer games for 4 hr. Magnetic resonance imaging of the hand and wrist, from the distal radius and ulnar head to the distal phalanges, and radiography of the cervical vertebrae were performed before and after playing computer games. For each dependent variable, a paired t-test was performed to identify significant changes before and after a 4-hr active computer game (p<.05). Results: The horizontal diameters of the flexor tendons in the index and middle fingers were significantly reduced after playing computer games. The horizontal diameters of the flexor tendons of other fingers did not show any significant differences, but there was a tendency toward a decrease after playing computer games. There was no significant change in the cervical lordosis angle before and after playing computer games. However, the cervical lordosis angle was relatively decreased. Conclusion: The results of this study showed that computer game exposure had direct and indirect effects on morphological changes of flexor tendons. In addition, playing computer games for long periods of time can have a negative effect on normal functioning of the musculoskeletal system, with the possible development of abnormalities. However, computer game exposure in adolescents cannot be decisively identified as a factor causing pathological symptoms, based on the results of this study alone. Thus, longterm longitudinal studies on the overall musculoskeletal system are necessary.
