Objectives: Problem behaviors pose a great obstacle to daily functioning in children with neurodevelopmental deficits and are an important target for treatment. In this study, we translated the Behavior Problems Inventory (BPI)-01 into Korean language and tested its psychometric properties. Methods: We attained the approval of the BPI author and performed standard translation-back translation. Then, professional caregivers examined appropriateness according to cultural and situational contexts in order to make necessary modifications of the Korean version of the BPI. Results: The BPI-01, Korea-Scales of Independent Behavior-Revised (K-SIB-R), and Child Behavior Checklist were completed for 98 autistic spectrum disorder or intellectual development disorder participants (mean age=28.3, standard deviation=7.3, range=10.1-51.7). The inter-rater reliability of the BPI-01 was found to be high (r=0.992-1.000). As for the results for concurrent validity for subscale items of BPI-01 and scales of SIB, correlations between SIB and BPI-01 subscales were statistically significant (r=0.357-0.672). Discussion: The Korean version of the BPI-01 showed good psychometric properties with high reliability and sufficient convergent validity. Further examination of the validity of BPI-01 should be carried out with inclusion of younger aged children and a closer look at less frequently occurring symptoms.

Objectives: REM sleep behavior disorder (RBD) has received little attention in epidemiologic studies. This study aimed to determine the prevalence of probable REM sleep behavior disorder (pRBD) in the elderly population and its clinical features. Methods: A random sample of 1,588 was selected from a roster of 14,050 elderly population living in Osan city. The subjects were asked to fill out the REM sleep behavior disorder screening questionnaire (RBDSQ). Subjects whose score were 5 or higher on RBDSQ underwent a diagnostic phase of person-to-person assessment by experts in RBD. Results: Among 1,588 subjects, 886 elderly subjects participated in the screening phase and 123 subjects were assessed in the diagnostic phase. Eleven subjects were diagnosed as having pRBD, so prevalence was 1.5% (95% CI=0.70-2.30%). The frequency of depression and cognitive decline was significantly increased in patients with pRBD compared to subjects without pRBD, and there was no difference in sleep disturbances between two groups. Conclusions: Probable REM sleep behavior disorder is not rare in the elderly but frequently under-recognized. More attention should be paid to evaluation and treatment of RBD.

Objectives : Recurrence of mood episodes associated with a specific season has been described in various mood disorders. Seasonal change in mood and behavior as a lifetime trait is also observed in healthy individuals. This study aimed at comparing the lifetime trait of seasonal variations of mood and behavior between bipolar disorder patients and controls as well as investigating associated factors of seasonality. Methods : Subjects were ninety-four clinically stable patients with bipolar disorder and 188 age- and sex-matched healthy controls. Seasonality of mood and behavior was assessed retrospectively on lifetime basis using Seasonal Pattern Assessment Questionnaire(SPAQ). Results : The patient group showed a higher median global seasonality score(GSS) of SPAQ and a higher rate of seasonal affective disorder(SAD) compared to the control group(p < 0.0001). For subjects showing prominent seasonality, the seasonal symptom profile and seasonal pattern was similar in both patient and control groups. In addition to the diagnosis, female gender was shown to be a predictor of seasonality in the multiple linear regression analysis(p = 0.045). Conclusion : This study suggests that lifetime trait of seasonality may be related to the susceptibility of bipolar disorder.

Objectives: Externalized behavioral problems are prevalent in adolescents, due to the difficulties associated with this developmental stage. Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD), as well as other psychiatric disorders, such as major depressive disorder, result in the manifestation of many behavioral problems during adolescence. Methods: For this report, we analyzed a sample of 31 adolescents, each of whom had presented with CD or ODD at Chosun University Hospital between 2002 and 2010. We separated subjects into depressed and non-depressed groups according to their Beck Depression Inventory scores (BDI<10, non-depressed ; BDI${\geq}$10, depressed). Then we analyzed for neuropsychological differences between the depressed and non-depressed groups. Results: In our sample, adolescents in the depressed group showed less of a stealing (deceitfulness and/or theft) behavioral pattern and presented with more anxiety symptoms, lower self-esteem, and greater sensitivity in interpersonal relationships, as compared to the non-depressed group. Conclusion: When adolescents exhibit disruptive behavior, clinicians should consider the underlying causes of the behavior.

The purpose of this study was to investigate the effects of an increase in self - determination experience on the behavior of young children with autism spectrum disorder by telepresence robot. As for research method, the study used AB design, two selected children engaged in activities with a telepresence robot in free play time in the morning. The activities were conducted in 19 sessions, twice a week, 15 to 40 minutes each. To investigate the effect of the activity on the child's behavior was observed using the behaviors of free play time and work time in the afternoon. All the process was recorded by a camera and then analyzed by frequency recording. The results of the study are as follows. First, the participation of young children with autism spectrum disorder in free play time increased. Second, choice-making or preference behavior of young children with autistic spectrum disorder were increased. This study suggests that increasing the self-determination experience of young children with autism spectrum disorders using telepresence robots increases their participation and increases their choice-making or preference behavior.

REM sleep behavior disorder is parasomnia characterized by unpleasant dreams and dream-enactment behaviors associated with excessive electromyography activity in REM sleep. This may appear idiopathic or secondary to other neurological or medical conditions. REM sleep behavior disorder, which appears to be idiopathic, most often implies the possibility of later neurodegenerative diseases due to synucleinopathy, so accurate diagnosis is important in predicting prognosis. For the diagnosis of REM sleep behavioral disorder, REM sleep without atonia, which appears in the polysomnography, is essential. Obstructive sleep apnea, trauma-related sleep disorders, and vigorous periodic leg movements during sleep are known as diseases that show dream enactment behavior in elderly patients. Considering that it may be accompanied by other sleep disorders that can mimic REM sleep behavioral disorders, it is important to differentiate sleep

Block copolymer (BCP) self-assembly in a film geometry has recently been the focus of increased research interest due to their potential use as templates and scaffolds for the fabrication of nanostructured materials. The phase behavior in a thin film geometry that confines polymer chains to the interfaces will be influenced by the interfacial interactions at substrate/polymer and polymer/air and the commensurability between the equilibrium period (L0) of the BCP and the total film thickness. We investigated the phase transitions for the films of block copolymers (BCPs) on the modified surface, like the order-to-disorder transition (ODT) by in-situ grazing incidence small angle x-ray scattering (GISAXS) and transmission electron microscopy (TEM). The selective interactions on the surface by a PS-grafted substrate provide the preferential interactions with the PS component of the block, while a random copolymer (PS-r-PMMA) grafted substrate do the balanced interfacial interactions on the surface. The thickness dependence of order-to-disorder behavior for BCP films will be discussed in terms of the surface interactions.

This study examined the effectiveness of the Filial Therapy program for children with Separation Anxiety Disorder (SAD). Subjects were 8 mother-child dyads each in the experimental and comparison groups. Mann-Whitney U-test and the Wilcoxon Matched-Pairs Signed-Ranks Test were performed following the therapeutic program. After application of the Filial Therapy program, results showed that, compared to the control group, (1) parents of SAD children in the experimental group significantly increased their level of empathic interactions with their children. AND (2) the experimental group children significantly reduced level of somatic complaints, anxious/depressed, and social problems. Conclusions were that Filial Therapy is an effective program for improvement of parent-child relationship of SAD children but not for changing problem behavior of SAD children.

Conversion disorder is a psychologically produced alteration or loss of physical functioning suggestive of a physical disorder. Conversion symptoms are often superimposed on organic disease and can be overlooked. Psychological techniques are central to the management include the following: avoiding confrontation with the patients; avoiding reinforcement or trivializing the symptoms; reviewing results of tests and exams and creating an expectation of recovery; educating the patient before a treatment is begun; evaluating the patient's emotional adjustment and considering it at a treatment; using caution in labeling the condition; considering referral for psychotherapy; establishing particularly a treatment plan and making a definite treatment program; adjusting patient' s environment; letting participate a family at appropriate time; developing a reinforcement program for a treatment of chronic symptoms; developing a home program for outpatients. Use behavior therapy reinforcement may be helpful with more chronic or resistant symptoms, especially when there is a history of vague or excessive somatic complaints or significant secondary gain.
