Background: Previous studies have indicated that people with social anxiety disorder (SAD) often experience spontaneous, recurrent images (SRI). It was assumed that Koreans with interdependent self-views may contain more features related to social contexts in their self-images than those reported in Western cultures. Aims: In the present study, we aimed to explore the prevalence and content of SRIs in individuals with SAD in Korea. Furthermore, we investigated the relationship between features of SRIs and variables of SAD. Method: Sixty-four individuals with SAD (27.00 ± 7.42 years, 64.1% female), diagnosed with SAD, completed self-report questionnaires related to social anxiety. Afterwards, a semi-structured interview was used to assess features and content of the individuals' SRI. Results: Thirty (47%) of the participants reported experiencing SRIs in social situations. The content of the SRIs were classified under three themes: negative self-images, negative images of others, and abstract images. The distress level of SRIs was positively associated with social phobia scales (r =.385, p <.05) and physical anxiety symptoms (r =.478, p <.05). Frequency of SRIs was positively associated with avoidance scores (r =.402, p <.05). Conclusions: The results demonstrated differences in the prevalence and content of the SRIs between Western and non-Western cultures. Fewer individuals with SAD in Korea reported having SRIs, and the content of these SRIs involved people other than the self. Some features of SRIs were associated with variables of SAD.

A three-tiered approach was used to assess erosion risks within the Nakdong River Basin in South Korea and included: (1) a screening based on topography and land use; (2) a lumped parameter analysis using RUSLE; and (3) a detailed analysis using TREX, a fully distributed watershed model. These tiers span a range of spatial and temporal scales, with each tier providing increasing detail and resolution. The first two tiers were applied to the entire Nakdong River Basin and the Naesung Stream watershed was identified as having the highest soil erosion risk and potential for sedimentation problems. For the third tier, the TREX watershed model simulated runoff, channel flow, soil erosion, and stream sediment transport in the Naesung Stream watershed at very high resolution. TREX was calibrated for surface flows and sediment transport, and was used to simulate conditions for a large design storm. Highly erosive areas were identified along ridgelines in several headwater areas, with the northeast area of Songriwon having a particularly high erosion potential. Design storm simulations also indicated that sediment deposition of up to 55 cm could occur. [Copyright &y& Elsevier]
