The so-called borderline children are characterised by disturbances in the sense of reality and interpersonal relationships, lack of control, fluctuation of functioning, uneven development and excessive anxiety. But the concept of borderline disorder of childhood is very difficult to define and diagnose in current classification system. The present study adapted the consensus symptoms in borderline children by Bemporad and Vera eight cases aged 7-11 were examined in 37 variables. Results are as follows 1) All subjects are boys and girl hardly be diagnosis n current diagnostic system and have many concurrent diagnoses. Common chief complaints in the sense of reality. 2) In KEDI-WISC test, the borderline children showed average intelligence, but performance IQ tends to be higher than verbal IQ. In Rorscharch test, they showed high thought disorder index, emotional instabilities and aggressive impulses. The results of TOVA suggested attentional deficit in half of the subjects. The organicity is not prominent. 3) Many of the borderline children were unwanted baby. Although primary care takers of all the subjects were their mothers there were moderate problems in caring attitude of their children and marital relationship with their husband. Sccioeconomic status was generally below middle class. Most of all subjects have delayed language development, but have overcome subsequently. Many subjects were rejected by peers because of their aggression. 4) The first visit of the subjects was about 6 years of age. Average duration of treatment was 2 years. All of them were treated in the outpatient basis except one. The effect of pharmacotherapy was doubtful and the necessity of long term play therapy was suggested. Although there were many limitations of method in present study, it was suggested that further research is needed for diagnostic criteria, epidemiology and treatment.

In this thesis, we investigate the psychosocial variables within the family environments of Attention Deficit Hyperactivity Disorder with (ADHD+CD/ODD) or without (ADHD) externalizing symptoms. The subjects in this research were 86 boys and girls(aged range 6 to 14 years) consisted of 20 ADHD, 22 comorbid ADHD(ADHD+CD/ODD) and 44 normal control group(NC). We have collected data on children and their mothers. The psychosocial variables included in the analysis are socioeconomic status, parent's educational level, life stress event, and the rate of psychiatric disorders in relatives. The self-reported questionnaires marital discord(MAS), parenting stress(PSI), and parenting attitute(MBRI) completed by mothers. The results indicated that ADHD+CD/ODD is supposed to have higher level of family adversity suggested by the lower SES, lower parental educational level, higher life stress events, and more psychic disorders in relatives compared with ADHD or normal control group. In MAS, ADHD+CD/ODD group has significantly the lowest scores on each factor of the measure of marital adjustment. Parents of ADHD+CD/ODD are much more likely to have positive parenting stress when compared with the parents of ADHD. Especially, mothers of ADHD+CD/ODD have the lowest tendency in the mean score on affective, accepted attitudd. In an inapropriate parenting attitude perceived by children, father of ADHD+CD/ODD have the most negative, contradictory attitude and mothers of ADHD+CD/ODD have the most restrictive, negative and contradictory attitude.

Objective：This study was designed to evaluate effects of methylphenidate(MPH) on event-related potentials(ERP) and continuous performance test(CPT) in attention-deficit hyperactivity disorder (ADHD) and to see the correlation between changes in ERP and changes in performance. Method：ERP and CPT were used to examine the acute effects of MPH(0.5mg/kg) in eleven ADHD boys(89-103 months old). Results：1) After MPH administration, P3 latency to nontarget stimuli at Fz was significantly decreased (p<0.01) and P2 amplitudes to target stimuli at Pz and at Oz and P3 amplitude to target stimuli at Cz were significantly increased(p<0.05). 2) Commission error and omission error in the CPT-X and commission error in the CPT-AX were decreased(p<0.01), and hits and perceptual sensitivity(d') in the CPT-X and d′ in the CPT-AX were increased(p<0.01). 3) The change of P3 latency to nontarget stimuli at Fz and the change of d′ in the CPT-X were negatively correlated(p<0.05), and the change of P2 amplitude to target stimuli at Pz and d′ in the CPT-AX were positively correlated(p<0.05). Conclusion：MPH improves change orienting reaction, the delivery of task relevant information, accuracy and perceptual sensitivity in ADHD. And the increase of ability to discriminate targets from non-targets reflects reduced evaluation time in large memory component task and enhanced change orienting reaction in simple task.

We studied the clinical characteristics of 45 children with tic symptoms, and a comparison was made according to their birth order patterns. The results were as follows. Sex ration was 14:1 higher for boys. The eldest children were 46.7%, single children, 15.6%, the youngest children, 33.3%, and twins 4.4% of all Organicity was suggested in 37.8%, early developmental problems in 71.1%, and family problems were in 89.9%. Among the co-existing problems, ADHD 46.7%, OCD 17.7%, Separation anxiety disorder 24.4%, GAD or anxiety dreams 17.8%, somatization disorder and enuresis 13.3% each, stuttering 8.9%, and other conditions. Overall, 84.4% of the patients have one or more co-existing conditions other than tic symptoms. When compared according to birth order patterns, the most significant difference was the time of onset The youngests have more incidences around the entrance period for elementary school(p<0.01). Among the twins, the lower birth-weight child was the patient. Summing up these findings, we concluded there were significant environmental factors working on the manifestation of tic and tourette disorders.

This Study has an aim to offer the basic materials to teach the establishment and practice of Hyo consciousness to teenagers after finding the degree of accomplishment about their filial piety as the changes of related variables for the subject of this study, the Middle school boys and girls. The results of this research were followings. 1. The objects of research's Hyo consciousness and filial piety was totally high. 2. The teenagers' Hyo consciousness was showed significant difference according to adolescent's sea school's place, parents' job, the level of parents' education, income level, religion, family composition, and the place people who were educated Hyo live. 3. The teenagers' filial piety was showed significant difference according to adolescent's sea mother's job, the level of father's education, religion, and the place people who were educated Hyo live. 4. The teenagers' filial piety was showed significant difference according to Hyo consciousness. 5. In the relative influence of changes of having influence on filial piety, the better relative changes for filial piety were expressed as sex, religion, the place people who were educated Hyo a lot live, and Hyo consciousness. That is, the more they had Hyo consciousness the more they practiced filial piety. and girl students was expressed higher than boy students in practicing.

Objectives: The objective of this study was to investigate the effect of pharmacological treatments for attention-deficit hyperactivity disorder (ADHD) on motor coordination, using the Developmental Coordination Disorder Questionnaire (DCDQ). Methods: The participants were recruited from April 2015 to November 2016 from the Department of Psychiatry of Asan Medical Center and were treated for 3 months with methylphenidate or atomoxetine. The illness severity at baseline and 3 months were scored using the ADHD Rating Scale (ARS), Clinical Global Impression-Severity Scale (CGI-S) and/or Clinical Global Impression-Improvement Scale (CGI-I). A total of 39 children with ADHD (age $8.0{\pm}1.4years$, 36 boys) completed the Advanced Test of Attention (ATA) and their parents completed the DCDQ at baseline and 3 months. The paired t-test, mixed between-within analysis of variance and correlation analysis were used. Results: The CGI-S (p<0.001), ARS (p<0.001), and fine motor/hand writing (p=0.005) on the DCDQ were significantly changed between pre-treatment and post-treatment. When the participants were divided into those who were suspected of having developmental coordination disorder (DCD) (n=23) and those who probably did not (n=16), the control during movement, fine motor/hand writing and general coordination scores on the DCDQ showed the main effects for group (p<0.001, p<0.001 and p<0.001, respectively). The fine motor/hand writing on the DCDQ has a significant main effect for time [F(1,37)=7.31, p=0.010, ${\eta}^2=0.405$] and the interaction effect between group and time was also significant [F(1,37)=4.63, p=0.038, ${\eta}^2=0.111$]. The baseline visual commission error on the ATA is significantly correlated with the changes in the DCDQ total scores (r=0.330, p=0.040). Conclusion: Our results provide preliminary evidence that pharmacological treatment for ADHD improves not only the core symptoms of ADHD, but also the motor coordination. Further studies are needed to confirm the effect of the pharmacological treatment for ADHD on the motor coordination.

In order to investigate the adolescent's beverage drinking pattern and its related ecological factors, a questionnaire survey was conducted with the subjects of 920 middle and high-school students,450 boys and 470 girls, residing in 4 cities of the Chungnam area. Of the subjects 65% liked, or liked very much, beverages and only 3.7% did not like beverages. They drank beverages 4.3 $\pm$ 4.0 times a week on average, but 10.4% of them drank beverages more than twice a day. Male students drank more frequently than the females. The intake frequency of carbonated drinks was 1.7 $\pm$ 2.3 a week which was about 40% of the total beverages. However, more students drank mainly ion beverages (33.6%) than carbonated drinks (28.7%). As the students took more balanced food and ate more regularly, their beverage drinking frequency decreased and those taking carbonated drinks also tended to decrease. The more frequent the students took fast food, the more frequent they drank carbonated beverages. The drinking frequencies for beverages or carbonated beverages were also less in students eating cooked rice with sidedishes as breakfast than in students eating others. The drinking frequency for carbonated drinks showed significant correlations with the students' activities such as the time spent using computers and watching TV got longer, the drinking frequency for soft drinks was also higher. When nutritional knowledge was higher, drinking frequency for carbonated drinks got lower. In conclusion, to make the adolescents improve their attitudes toward drinking beverages and to prevent excessive drinking of carbonated drinks, they should be educated not only on the nutritional knowledge and the proper intake of beverages, but also on good dietary habits including balance, regularity, and types of meals. Proper snacking and fast food consumption also should be taught. Since ion beverages were taken more frequently than carbonated drinks among adolescents, further study is recommended on the impact of excessive intake of ion beverages.

Purpose: The purpose of this study was to estimate dietary flavonoids intake of Korean adolescents. Methods: Using data from the 2007-2012 Korean National Health and Nutrition Examination Survey, a total of 3,957 subjects aged 12-18 were included in this study. We estimated individual daily intake of total flavonoid and six flavonoid classes including flavonols, flavones, flavanones, flavan-3-ols, anthocyanidins, and isoflavones by linking food consumption data with the flavonoids in the commonly consumed food database. The distribution of sociodemographic, health-related, and dietary factors according to flavonoids intake was examined. Results: Average dietary flavonoids intake of the study subjects was 195.6 mg/d in girls, and 189.4 mg/d in boys. The highest flavonoids intake group consumed significantly more fiber, vitamin C, legumes, fruits, and vegetables (p < 0.01) and less fat, grains, meats and dairy foods than other lower consumption groups (p < 0.001). Dietary flavonoid intake showed negative correlation with waist circumference and systolic blood pressure (p < 0.05). Conclusion: This study provided basic data for estimation of flavonoids intake of Korean adolescents. Further research will be required for analysis of the association of flavonoids intake and health-related factors such as cardiovascular risk factors.

The present study was designed to investigate variables associated with mother-child interaction patterns of Attention Deficit Hyperactivity Disorder(ADHD), and also to evaluate short-term effects of stimulant medication on the behaviors of ADHD children and their mothers during interaction. 15 ADHD boys(ages 5${\sim}$10 years) were treated with metylphenidate(0.5mg/kg per day) for 1 month, and their behaviors as well as their mothers for the 10 minute free play and 20 minute task performance period were videotaped through one-way mirror. The childrens attention was also evaluated using the Continuous Performance Task(CPT) and ratings of their hyperactive behaviors were obtained from their mother prior to the treatment. The videotaped interaction were rated according to the Response Class Matrix developed by Mash, Terdal & Anderson(1973). Results indicated that percentage of behavior of the mother and child during interaction was highly correlated with each other, which, in turn, was highly correlated with the symptom severity of the ADHD child. That is the more severe the cognitive and behavioral symptoms of ADHD, the more negative the interaction behavior pattern was. After 4 weeks of stimulant medication the mothers as well as the ADHD children showed a significant decrease in the percentage of negative-aggressive behavior during the task performance period. The results indicated that negative interaction behavior of the mothers was in large part a response to the negative behavior of their ADHD children.

Objectives: The objective of this study was to examine the effects of osmotic-controlled release oral delivery system methylphenidate on changes in regional cerebral blood flow (rCBF) in children with attention-deficit hyperactivity disorder (ADHD) using single photon emission computed tomography (SPECT). Methods: A total of 26 children with ADHD (21 boys, mean age: $9.2{\pm}2.05$ years old) were recruited. Each ADHD participant was examined for changes in rCBF using technetium-99m-hexamethylpropylene amine oxime brain SPECT before and after 8 weeks methylphenidate medication. Brain SPECT images of pediatric normal controls were selected retrospectively. SPECT images of ADHD children taken before medication were compared with those of pediatric normal controls and those taken after medication using statistical parametric mapping analysis on a voxel-wise basis. Results: Before methylphenidate medication, significantly decreased rCBF in the cerebellum and increased rCBF in the right precuneus, left anterior cingulate, right postcentral gyrus, right inferior parietal lobule and right precentral gyrus were observed in ADHD children compared to pediatric normal controls (p-value<.0005, uncorrected). After medication, we observed significant hypoperfusion in the left thalamus and left cerebellum compared to pediatric normal controls (p-value<.0005, uncorrected). In the comparison between before medication and after medication, there was significant hyperperfusion in the superior frontal gyrus and middle frontal gyrus and significant hypoperfusion in the right insula, right caudate, right middle frontal gyrus, left subcallosal gyrus, left claustrum, and left superior temporal gyrus after methylphenidate medication (p-value<.0005, uncorrected). Conclusion: This study supports dysfunctions of fronto-striatal structures and cerebellum in ADHD. We suggest that methylphenidate may have some effects on the frontal lobe, parietal lobe, and cerebellum in children with ADHD.
