Objective : Social anxiety disorder (SAD) is characterized by fear of social threat and exhibits limbic hyper-reactivity toward social stimuli such as emotional faces. A previous study identified the uncinate fasciculus (UF) sub-tract as particularly related to facial memory. To explore the white matter tract relating to face-specific brain regions, we investigated the UF sub-tract in SAD. Methods : The diffusion tensor images of 22 patients with SAD and 20 healthy controls were analyzed with tractography. The UF sub-tract was delineated using the regions of interest of face patches in the anterior temporal lobe and the orbitofrontal cortex, and fractional anisotrophy (FA) and total number of streamlines (ST) were analyzed. We examined the group comparison of FA and ST of the UF sub-tract and correlations of FA and ST with the social anxiety symptoms such as the Liebowitz Social Anxiety Scale (LSAS), the Social Interaction Anxiety Scale (SIAS), the Social Phobia Scale (SPS) and the Fear of Negative Evaluation scale (FNE) in SAD. Results : There were no group differences in FA and ST of the UF sub-tract. However, negative correlations were observed between ST of the right UF sub-tract and severity of social anxiety symptoms (LSAS, r_s=-0.480, p=0.024; SIAS, r_s=-0.580, p=0.005; SPS, r_s=-0.590, p=0.004; FNE, r_s=-0.675, p=0.001) in patients with SAD. Conclusion : Although patients with SAD did not show quantitative abnormalities in the UF sub-tact connecting face-specific brain regions, this structure seems to play a role in the symptom severity of SAD.

Purpose: This study aims to identify the relationship between nursing students' social anxiety and communication ability, and in particular, to determine the mediating effect of self-efficacy. Methods: A total of 187 nursing students enrolled at four universities in Korea completed surveys between August and September 2020. The measurements included the Global Interpersonal Communication Competence Scale, self-efficacy scales, and interaction anxiousness scales. Data were analyzed using descriptive statistics, an independent t-test, one-way ANOVA, Pearson's correlation, multiple regression following the Baron and Kenny method, and bootstrapping for mediation. Results: Communication ability was significantly negatively correlated with social anxiety (r=-.61, p<.001) and significantly positively correlated with self-efficacy (r=.77, p<.001). Furthermore, self-efficacy had a partial mediating effect on the relationship between social anxiety and communication ability. Conclusion: The findings of this study suggest that communication ability can be improved if individual characteristics such as social anxiety and self-efficacy are considered. Therefore, when developing communication ability improvement programs for nursing students in the future, it is considered important to actively consider these personal characteristics.

Background: A chronic social defeat stress (CSDS) model has been proposed as relevant to stress-induced behavioral change in humans. In this study, we examined the effect of Korean Red Ginseng (KRG) on CSDS-induced mood disorders and protein expression in an animal model. Methods: To evaluate the effect of KRG on social defeat stress, test mice were exposed in the resident aggressor's home cage compartment for 14 days beginning 1 h after KRG treatment (10, 20, and 40 mg/kg, per oral (p.o.)). After the exposure, behavioral tests to measure anxiety, social interaction, and depression-like behavior were performed. To investigate the underlying mechanism, N-methyl-D-aspartate receptor expression levels in CSDS-induced mice were evaluated using Western blot analysis. Results: CSDS induced anxiety-like behaviors by decreasing central activity in the open-field test and open-arm approach in the elevated plus maze test and led to social avoidance behavior in the social interaction test. CSDS mice showed upregulated NR1, NR2A, and NR2B expression in the hippocampus. KRG 20 and 40 mg/kg ameliorated anxiety-like activities and KRG 20 mg/kg alleviated social avoidance by decreasing time in the corner zone. KRG treatment recovered CSDS-induced NR1, NR2A, and NR2B protein levels in the hippocampus. Conclusion: These results indicate that KRG has a therapeutic effect on CSDS-induced mood disorder by alleviating N-methyl-D-aspartate receptor overexpression in the hippocampus.

To detect anxiolytic activity from Sanguisorbae Radix we used various animal models of fear or anxiety that are sensitive to known anxiolytic drugs. While diazepam showed significant anxiolytic activities in all five animal models empolyed in this study, $5-HT_3$ antagonist ondansetron and ethylacetate fraction of Sanguisorbae Radix did show anti-anxiety effects in social interaction and two compartment exploration tests. Ethylacetate fraction of Sanguisorbae Radix and 5-HT related drugs like ondansetron and buspirone, however, seem to have merit over diazepam in terms of not causing drowsiness. Among ten subfractions obtained from ethylacetate fraction of Sanguisorbae Radix by silica gel chromatography, subfraction I showed higher anxiolytic activities than subfraction DEF in two animal models, social interaction and two compartment exploration tests. There is growing evidence for the role of 5-HT in the control of anxiety. We hope that new compound(s) will be found from the active fractions of Sanguisorbae Radix as a potential anxiolytic agent in the future.

Objective : The amygdala has been considered to be a critical region in the pathophysiology of social anxiety disorder, but subregional connectivity pattern has not been examined yet despite lots of previous functional neuroimaging studies. Methods : Resting-state functional magnetic resonance imaging data was obtained in 19 patients with social anxiety disorder and 20 normal controls, and default mode functional connectivity with each of basolateral, centromedial and superficial areas of the amygdala was measured and compared between the two groups. Results : Differential amygdala-based networks between the two groups were distributed to all over the brain. In particular, however, a bias on the amygdala-cingulate pathway was observed in the superficial amygdala only. Connectivity strengths between the superficial amygdala and perigenual anterior cingulate cortex were correlated with scores of social interaction and avoidance. Conclusion : Our findings provide new insights into understanding of the intrinsic cognitive bias model of social anxiety disorder. An abnormality in superficial amygdala-anterior cingulate connectivity may influence on cognitive processing of socially-relevant information in social anxiety disorder.

The purpose of this study is to identify factors that improve psychological health of Korean navies who are dispatched overseas. Specifically, we examined the effects of the navies' occupational calling, perceived social support, and their interaction on anxiety. One hundred thirty-eight dispatched navies were recruited, and they completed the Korean calling scale, multifaceted social support scale, and anxiety scale-Y form. Results showed that after controlling for gender, marital status, and the previous experiences of dispatch, those who had a higher level of occupational calling and social support experienced a lower level of anxiety respectively before they were dispatched overseas. Furthermore, the significant interaction effect between occupational calling and social support on anxiety confirms that the effect of social support on anxiety is more prominent for those who have lower level of occupational calling. We discussed the implications of these results, study limitations, and directions for future research.

The purpose of this study was to investigate the differences in social anxiety and stress coping style by the college students' levels of self-efficacy. The convenience sample consisted of 400 college students in six universities. The data were collected from May to June in 2013 using the following instruments: the Self-Efficacy Scale, the Interaction Anxiousness Scale and the Ways of Coping Questionnaire. Descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient were used to analyze the data using SPSS 21.0. Self-efficacy was found to have negative relation with social anxiety and positive relation with active coping style while social anxiety was negatively related to active coping style and positively to passive coping style. There were differences in social anxiety and stress coping style in accordance with the level of self-efficacy. The higher group in self-efficacy used more active coping than the lower group. The support and intervention program to increase self-efficacy would be effective in decreasing social anxiety and increasing active coping style among college students.

An increase of the interaction speed can lead to the problem of over-relations. Due to psychological and temporal burdens caused by the excessive relationship, users feel fatigue and users are avoiding using SNS. SNS fatigue and SNS anxiety is regarded as SNS stress related to the side effects caused by the SNS use. This study is to approach negative view which is SNS stress and find out causes of stress from the over-relation of interaction. This study used total of 261 samples from Facebook users. As a results, all hypothesis are accepted using SEM(Structural Equation Model). Information sharing and communication have positive effect on social interaction overload and it causes technostress. The results of this study show that SNS characteristics occurs technostress. This study is significant in that it examines that the features of SNS have negative results.
