A social phobia is an anxiety disorder characterized by extreme fear and phobic avoidance of social and performance situations. Medications or cognitive-behavior methods have been mainly used in treating it. These methods have some shortcomings such as being inefficient and difficult to apply to treatment. Lately the virtual rcality technology has been applied to dcal with the anxiety disorders in order to compcnsate for these defects. A virtual environment provides a patient with stimuli which cvokes a phobia. and the patient's exposure to the virtual phobic situation make him be able to overcome it. In this study, we suggested the public speaking simulator based on a personal computer for the treatment of social phobia. The public speaking simulator was composed of a position sensor. head mount display and audio system. And a virtual environment for the treatment was suggested to be a seminar room where 8 avatars are sitting. The virtual environment includes a tracking system the trace a participant's head-movement using a HMD with position sensor and 3D sound is added to the virtual environment so that he might fcel it realistic. We also made avatars' motion and facial expression change in reaction to a participant's speech. The goal of developing public speaking simulator is to apply to treat fear of public speaking efficiently and economically. In a future study. we should get more information about immergence and treatment efficiency by clinical test and apply it to this simulator.

35 children(17 boys, 18 girls) with Recurrent Abdominal pain(RAP) without apparent organic causes, referrd from pediatric department of Seoul National University Children's Hospital were studied during 1988. 7. 1 ${\sim}$ 1989. 2. 28. The aims of this study are to examine clinical characteristics of the patients with RAP, to find possible factors influencing the onset and the course of the disorder, to evaluate the psychological status and the relationship with psychiatric diagnoses. The study subjects were compared with the age and sex matched control subjects on measures of social and school functioning, family-environment, behavior traits by CBCL and parent-environment rating scale. All patients and their mothers were interviewed by a child psychiatrist. The results were as follows ; 1) Abdominal pain was found to be more frequent when with a care taker, and related with traumatic life stresses such as separation from parents, death of family members. 2) Family members of the patients with RAP also had a high rate of a history of gastrointestinal dysfunctions with could not be attributed to organic etiologies. 3) Among 35 patients with RAP, 16 were diagnosed as psychiatric disorders. They were adjustment disorders (4), overanxious disorders (4), depression (2), tic disorders (2), attention deficit disorders (2), separation anxiety disorders (1), enuresis (1). 4) On CBCL, the patients with RAP were more internalized, socially less competent and less active compared with the control subjects. 5) According to the parent-environment rating scale, the patients with RAP had more conflicts with their parents about control issues. Family members of the patients with RAP were socially less competent and less abjustable. The parents of the patients with RAP were more affectionate and spent more time with their children but they were unfair and vague on instruction and discipline.

We reviewed existing studies and proposed future research on the sustainability of short-term effects, and of the Yongin Emotion Management Training program (Y-EMT). In this study, we conducted Y-EMT to verify its effectiveness in relation to affective disorders associated with chronic schizophrenia. Thirty-five patients were assigned to the experimental group, and 35 to the control group. First, results of repeated-measures analysis supported the effectiveness of Y-EMT. Comparisons of the results on the pre-test with those for the 5-month and 1-year post-training tests showed significant differences in mean scores between the experimental and control groups. Furthermore, these differences persisted at the 2-year follow-up. Second, in the experimental group, interactions between emotional behavior and expression, self-efficacy, and changes in interpersonal relationships showed significant effects at 5 months after the program ended, and these effects continued to increase up to 1 year post-training. Taken together, the findings indicate that, to maintain the effects of therapy in patients with chronic schizophrenia, patients should undergo Y-EMT along with cognitive rehabilitation training and social skills training. Human relations training such as Y-EMT is most helpful for rehabilitation when it is paired with high levels of medication.

Objectives : The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). Methods : A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. Results : Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.05). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.05). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. Conclusion : Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.

This study examined for which socio-economic difference effects on brain function and Problem behavior syndrome in children. About a children with no disorders, diseases or cognitive dysfunction-30 were from LIC children and another 30, from MC ones, the study was conducted by measuring and analyzing the data using brain function analysis and K-CBCL from January to April, 2013. The results of the study are as follows. First, it was found that the ratio of LIC's theta(${\Theta}$) and SMR waves and that of delta(${\delta}$), high beta(${\beta}h$), alpha(${\alpha}$) and low beta(${\beta}l$) waves showed significantly higher values than MC children. Second, concerning the symptoms of child behavioral problems, LIC showed significantly higher values than MC children in symptoms of the body, depression and anxiety, social immaturity, thinking problems, attention problems, aggression, internalization, externalization, overall behavioral problems, and emotional instability. MC children showed significantly higher values than LIC chidren in symptoms of social, academic-performance, total social skills. In conclusion, the significant difference of the brain functions and the symptoms of child behavioral problems between LIC and MC children showed that the socio-ecnomic difference has an influence on the same functions and symptoms above.

The discovery of the mirror neuron system (MNS) is one of the most important neuroscientific achievements in the 20th century. Some researchers had reported that MNS dysfunction was discovered in autism spectrum disorders (ASD). Finally, the 'broken mirror' theory of ASD was announced in the mid 2000's. According to this theory, ASD cannot simulate the mind and behavior of others due to MNS dysfunction; therefore, they cannot imitate the behaviors and empathized with the mind of others. However, ASD does not always show imitation problems. The researchers who have criticized the 'broken mirror' theory proposed the 'social top-down response modulation (STORM)' theory. On STORM theory, the medial prefrontal cortex or temporo-parietal junction, brain areas related with mentalising, might modulate MNS according to social context. We compared the strengths and weaknesses of each theory.

Objectives : It is known that adolescents with autism spectrum disorder (ASD) often concurrently exhibit attention-deficit hyperactivity disorder (ADHD). The objective of this study is to investigate how ADHD symptoms modify clinical characteristics in adolescents with ASD. Methods : Subjects were recruited from the Program for the Education Enrichment of Relational Skills program, which is a program for adolescents with ASD to promote and train social skills. The study participants and their parents completed the study questionnaires, such as the ADHD rating scale, Autism Diagnostic Observation Schedule, and Korean version of Child Behavior Checklist. Results : Adolescents with ASD and ADHD (N=19) were found to have more impaired sociality, less open communication with their parents, and more behavioral and emotional problems compared with adolescents with ASD, and without ADHD (N=28). Conclusion : Although further research is needed, the results of our study suggest that adolescents with ASD present different clinical characteristics when comorbid with ADHD.

The dysfunction of either or both noradrenaline and serotonin system are important in the pathophysiology of depression. Previous reports have suggested that there may be an important interaction between these two systems. Recently, some investigators have suggested that the combination of tricyclic antidepressants(TCAs) and selective serotonin reuptake inhibitors(SSRIs) would produce a rapid synergistic effect on down-regulation of either or both of these two systems and that this combination may produce a more rapid and absolute antidepressant effect. We compared the treatment efficacy, treatment associated side effects, treatment satisfaction, and the quality of life between the combination therapy of dothiepin-sertraline as well as the therapy of dothiepin alone in the treatment of major depressive disorder and dysthymic disorder. In our study, the combination therapy of dothiepin and sertraline produced a more rapid and absolute antidepressant effect than dothiepin alone. And the patients with combination therapy experienced relatively high treatment satisfaction than the patients with dothiepin therapy. The patients' quality of life improved more rapidly in the combination therapy, especially, in the health perception, social behavior, and life satisfaction, than dothiepin alone. These results support the hypothesis that the combination of TCA and SSRI may produce a rapid synergistic effect on either or both norepinephrine and serotonin system, and more rapid antidepressant effect and high treatment satisfaction.

Children above age of two are able to have sexual excitement, and they actively seek the pleasure actively or passively through touch and masturbation. In late $60_s$ and early $70_s$, Masters, obstetrician, and Johnson, social worker, illustrated four phases of human sexual responses, namely excitement, plateau, orgasmic and resolution phases in both sexes, and multiple orgasms in the female. Their treatment principles of sexual dysfunctions were largely based on behavioral model, introducing the concepts of sensate focus, dual therapy and sex education. Following Masters and Johnson, Kaplan, psychiatrist and psychoanalyst, in the early and mid-$70_s$ introduced new sex therapy which was based on the combination of analytically-oriented psychotherapy and behavior therapy, and classified sexual dysfunctions into three categories such as desire excitement and orgasmic phase disorders. Since $1980_s$ other medical fields joined the stream, putting the concentrated effort on the treatment of the impotence in the male. They have developed penile prosthesis, local injection therapy, and the administration of oral medications. Nowadays Sildenafil(Viagra) seems the best choice for the treatment of the impotence in the male.

Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator's note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.
