The purpose of this review was to investigate the neurophysiological and neuroimaging characteristics of patients with depression and anxiety reported in previous studies. A literature search was conducted using Medline and psychiatric textbooks. "Electroencephalography (EEG)", "Event Related Potentials (ERP)", "functional neuroimaging", "heart rate variability (HRV)" and "depression or anxiety" were used as key words. A physiological finding indicated that there was a higher degree of relativity with regards to prefrontal dysfunction in patients with depression. Right prefrontal lobe hyperactivity and left prefrontal hypoactivity were consistently observed, and abnormalities were observed in other regions (ACC, hippocampus, amygdala, etc.). Therefore, dysfunctions in these areas are related to depressive symptoms. In patients with anxiety disorder, each emotional condition showed specific activation patterns in different brain regions, such as the prefrontal cortex, occipital lobe, temporal lobe, hippocampus, and limbic system, including the amygdala. However, in the majority of patients with anxiety disorder, the degree of activation was higher in the right hemisphere than in the left hemisphere. The current data supports that there is a difference in brain dysfunction characteristics between depression and anxiety and that the different activations of various brain regions would play a significant role in the pathophysiology of depression and anxiety disorder.

Objectives : The purpose of this study is to investigate whether the ability of facial affect perception is associated with schizotypal personality traits in healthy normal controls. Methods : 241 normal subjects were recruited in this study. The age range of all subjects was from 19 to 63 years. The schizotypal personality questionnaire(SPQ) and facial affect identification test(FAIT), which were developed and standardized in Korea, were applied. Subjects from high 1 standard deviation(H group, N=40) and low 1 standard deviation(L group, N=26) on SPQ score were compared. Results : We found that the H group showed significantly reduced ability on the correctness of sadness and neutral compared with the L group. But, no significant association between SPQ and intensity or reaction point was observed in all subjects. Conclusion : This study suggests the individuals with high schizotypal personality trait have impairments on the facial affect identification. Also, these findings may provide the reasonable explanation of social cognition deficit of schizotypal personality disorder.

Objective:We investigated the characteristics of cellular phone use and its association with psychological problems among adolescents. Methods:A total of 332 adolescent students were recruited for this study. The participants’ self-reported characteristics of cellular phone use and the psychological problems caused by this were tested by using the Excessive Cellular Phone Use Survey (ECPUS), the Children’s Depression Inventory (CDI), Spielberger’s State-Trait Anxiety Inventory for Children (STAIC) and the Korea-Youth Self Report (K-YSR). Results:The excessive user group made more use of text messages and they spent more time and paid higher fees than the comparison group. They expressed severer depression and anxiety and they had more behavior problems and lower school performance than the comparison group. The ECPUS score was positively correlated with score of the CDI, STAIC and the behavior problem scales of the K-YSR, and the ECPUS score was negatively correlated with the school performance scale of the K-YSR. Conclusion:Our findings suggest that excessive cellular phone use by adolescents may be related to psychological problems. Careful education about the use of cellular phones and intervention are recommended for adolescents who excessively use cellular phones.
